    Obesity is a condition in which the body fat stores are increased to an extent which impairs health and leads to serious health consequences. The amount of body fat is difficult to measure directly, and is usually determined from an indirect measure - the body mass index (BMI). Increased BMI in obese persons is directly associated with an increase in metabolic disease, such as type 2 diabetes mellitus. This Analytical cross sectional study was undertaken to assess the relation between obesity and glycemic control of body by measuring fasting serum glucose and glycosylated hemoglobin. This study was carried out in the Department of Physiology, Mymensingh Medical College, Mymensingh from 1st July 2011 to 30th June 2012 on 120 equally divided male and female persons within the age range of 25 to 55 years. Age more than 55 years and less than 25 years and diagnosed case of Hypothyroidism, Cushing's syndrome, polycystic ovary, Antipsychotic drug user and regular steroid users were excluded. Non probability purposive type of sampling technique was used for selecting the study subjects. Measurement of body mass index was done as per procedure. Fasting serum glucose was estimated by glucose oxidase method and Glycosylated hemoglobin by Boronate Affinity method. Statistical analysis was done by SPSS (version 17.0). Data were expressed as Mean±SE and statistical significance of difference among the groups were calculated by unpaired student's 't' test and Pearson's correlation coefficient tests were done as applicable. The Mean±SE of fasting serum glucose was significant at 1% level (P value obese group of BMI. There was no significant difference of glycosylated hemoglobin level between control and study groups. But there was positive correlation within each group. Fasting serum glucose also showed a bit stronger positive correlation with BMI. Both obese male and female persons showed higher levels of fasting serum glucose and glycosylated hemoglobin. The observed positive

    The poor correlation between serum and urine glucose measurements has led to the development of new techniques for monitoring the blood glucose level in diabetic patients. Either a nurse or the patient can perform these tests, which involve spreading a single drop of blood onto a reagent strip. A colour change that is proportional to the serum glucose level can be read visually or with a reflectance meter. Evaluated against simultaneous serum glucose levels determined by the hospital biochemi...

    Differences in small solutes transport rate (SSTR) during peritoneal dialysis (PD) may affect water and solutes removal. Patients with high SSTR must rely on shorter dwell times and increased dialysate glucose concentrations to keep fluid balance. Glucose absorption during peritoneal dialysis (PD), besides affecting glucose and insulin metabolism, may induce weight gain. The study aimed at examining acute glucose and insulin serum level changes and other potential relationships in PD patients with diverse SSTR. This cross-sectional study used a modified peritoneal equilibration test (PET) that enrolled 34 prevalent PD patients. Zero, 15, 30, 60, 120, 180, and 240-minute glucose and insulin serum levels were measured. Insulin resistance index was assessed by the homeostasis model assessment (HOMA-IR) formula. SSTR categories were classified by quartiles of the four-hour dialysate/serum creatinine ratio (D(4)/P(Cr)). Demographic and clinical variables were evaluated, and the body mass index (BMI) was estimated. Correlations among variables of interest and categories of SSTR were explored. Glucose serum levels were significantly different at 15, 30, and 60 minutes between high and low SSTR categories (p = 0.014, 0.009, and 0.022). Increased BMI (25.5 +/- 5.1) and insulin resistance [HOMA-IR = 2.60 (1.40-4.23)] were evidenced overall. Very strong to moderate correlations between insulin levels along the PET and HOMA-IR (r = 0.973, 0.834, 0.766, 0.728, 0.843, 0.857, 0.882) and BMI (r = 0.562, 0.459, 0.417, 0.370, 0.508, 0.514, 0.483) were disclosed. CONCLUSIONS; Early glucose serum levels were associated with SSTR during a PET. Overweight or obesity and insulin resistance were prevalent. An association between insulin serum levels and BMI was demonstrated.

    Full Text Available Growth hormone exerts several metabolic effects, including effects on proteins, fats and carbohydrates. Among the many metabolic activities of GH, two contradictory actions were described: acute and early insulin-like activity and chronic and late anti-insulin like activity also called diabetogenic activity. A dramatic increase in plasma concentration of GH was found during endurance exercise, but its role during exercise is not well known. According to its metabolic effects a possible role of growth hormone may be in maintenance of glucose level during exercise. The aim of this study was to analyze dynamics of changes in GH and glucose levels during acute workload and in the recovery period, in a group of well trained athletes. All the subjects exercised for 30 minutes on cycle ergometer in sitting position (work intensity 50% of VO2 max, RPM 60/min. Serum GH concentrations were measured by IRMA (immunoradiometric assays method in blood samples obtained at rest and 6-min intervals during exercise, and 15-min intervals during recovery period. Serum glucose levels were determined by standard enzymatic method glucose oxidase (GOD PAP at the same intervals. There were no correlations between serum GH and glucose levels either during exercise or in the recovery period. There were no differences between glucose levels during exercise, so we can not exclude possible role of GH in glucose concentration maintenance.

    The effect of neutral detergent fiber (NDF) from coconut kernel (Cocos nucifera L) in rats fed 5%, 15% and 30% level on the concentration of blood glucose, serum insulin and excretion of minerals was studied. Increase in the intake of fiber resulted in significant decrease in the level of blood glucose and serum insulin. Faecal excretion of Cu, Cr, Mn, Mg, Zn and Ca was found to increase in rats fed different levels of coconut fiber when compared to fiber free group. The result of the present investigation suggest that inclusion of coconut fiber in the diet results in significant hypoglycemic action.

    Full Text Available Introduction: The effect of Tribulus terrestris (TT on serum glucose and lipid levels was investigated in an experimental model of diabetes mellitus in rats. Methods: Female Wistar rats were divided into control, TT-treated control, diabetic, glibenclamide-treated, and TT-treated diabetic groups. For induction of diabetes, streptozotcin (STZ was administered (60 mg/Kg. Meanwhile, TT-treated groups received TT mixed with standard pelleted food at a weight ratio of 6.25% for 6 weeks. Serum glucose and lipid levels were determined before the study and at the 3rd and 4th week after the study. Results: Serum glucose was significantly lower in TT-treated diabetic rats at 3rd and 6th weeks as compared to untreated diabetics (p<0.01 and p<0.005, respectively. In addition, serum total cholesterol, triglyceride, and LDL-cholesterol showed a significant reduction in TT-treated diabetic rats as compared to untreated diabetics (p<0.05. On the other hand, HDL-cholesterol level did not change significantly in TT-treated diabetic group as compared to untreated diabetic group. Conclusions: Oral administration of TT has a significant hypoglycemic effect and in long term leads to appropriate changes in serum LDL-cholesterol, total cholesterol, and triglyceride levels, but does not affect HDL-cholesterol levels in diabetic rats.

    Objective: To investigate the changes of serum leptin, insulin levels and blood sugar contents in pregnant women with gestational glucose metabolism disturbances. Methods: Fasting and 3h after oral 50g glucose serum levels of leptin were measured with RIA in 36 pregnant women with glucose metabolism disturbances (gestational diabetes mellitus or gestational impaired glucose tolerance) and 34 controls. Also, fasting serum insulin levels (with CLIA) and blood sugar contents 1h after oral 50 glucose (with glucose oxidase method) were determined in all these subjects. Results: 1. Serum levels of leptin in pregnant women with glucose metabolism disturbances were 14.9 ± 4.3 μg/L (vs controls 9.8 ± 1.7 μg/L, P<0.01). 2. The serum levels of insulin and 1 h post - 50g glucose blood sugar contents in pregnant women with glucose metabolism disturbances were 12.9±4.3mU/L and 11.0±1.4mmol/L respectively, which were both significantly positively correlated with the serum leptin levels (r=0.835, r=0.758 respectively) (vs levels in controls: 8.45±3.0mU/L and 7.84±1.3mmol/L). Conclusion: Elevation of fasting serum levels of leptin was demonstrated in pregnant women with glucose metabolism disturbances and the level of leptin was positively correlated with that of insulin and blood sugar.

    Objective: To explore the relation of local cerebral FDG uptake value of glucose to the changes of prolactin (PRL), growth hormone (GH) and cortisol levels in serum during epilepsy. Methods: 76 epileptic patients with solitary epileptic focus were examined by 2-deoxy-2-[ 18 F] fluoro-D-glucose ( 18 F-FDG) positron emission tomography (PET) imaging and the FDG uptake value of epileptic foci were measured. Serum PRL, GH and cortisol levels of the patients were determined by radioimmunoassay (RIA) before and after seizures. Results: During ictal studies, all patients showed increased FDG uptake of epileptic foci compared with that in interictal phase. The serum PRL, GH and cortisol levels were significant higher after seizures. The changes of hormone levels correlated significantly with the lengths of seizure free intervals (SFIs) and with the types of seizures. But the variations of hormone levels had no relation with the site and FDG uptake of epileptic foci. In patients with absentia seizures, no significant increase was observed in serum PRL and cortisol levels. The changes of GH were not related with the types of seizures. Also, it was found that changes of hormone levels had significant relations to the lengths of SFIs. Conclusions: Serum PRL, GH and cortisol levels were significantly different before and after seizures. This study suggests that changes of postictal hormone levels correlated significantly with the types of seizures and lengths of SFIs, but the changes of hormone levels are not related with the site and FDG uptake of epileptic foci

  11. Decreased serum glucose and glycosylated hemoglobin levels in patients with Chuvash polycythemia: a role for HIF in glucose metabolism

    McClain, Donald A.; Abuelgasim, Khadega A.; Nouraie, Mehdi; Salomon-Andonie, Juan; Niu, Xiaomei; Miasnikova, Galina; Polyakova, Lydia A.; Sergueeva, Adelina; Okhotin, Daniel J.; Cherqaoui, Rabia; Okhotin, David; Cox, James E.; Swierczek, Sabina; Song, Jihyun; Simon, M.Celeste; Huang, Jingyu; Simcox, Judith A.; Yoon, Donghoon; Prchal, Josef T.; Gordeuk, Victor R.

    2012-01-01

    In Chuvash polycythemia, a homozygous 598C>T mutation in the von Hippel-Lindau gene (VHL) leads to an R200W substitution in VHL protein, impaired degradation of α-subunits of hypoxia inducible factor (HIF)-1 and HIF-2, and augmented hypoxic responses during normoxia. Chronic hypoxia of high altitude is associated with decreased serum glucose and insulin concentrations. Other investigators reported that HIF-1 promotes cellular glucose uptake by increased expression of GLUT1 and increased glycolysis by increased expression of enzymes such as PDK. On the other hand, inactivation of Vhl in murine liver leads to hypoglycemia associated with a HIF-2-related decrease in the expression of the gluconeogenic enzymes genes Pepck, G6pc, and Glut2. We therefore hypothesized that glucose concentrations are decreased in individuals with Chuvash polycythemia. We found that 88 Chuvash VHLR200W homozygotes had lower random glucose and glycosylated hemoglobin A1c levels than 52 Chuvash subjects with wildtype VHL alleles. Serum metabolomics revealed higher glycerol and citrate levels in the VHLR200W homozygotes. We expanded these observations in VHLR200W homozygote mice and found that they had lower fasting glucose values and lower glucose excursions than wild-type control mice but no change in fasting insulin concentrations. Hepatic expression of Glut2 and G6pc but not Pdk2 was decreased and skeletal muscle expression of Glut1, Pdk1 and Pdk4 was increased. These results suggest that both decreased hepatic gluconeogenesis and increased skeletal uptake and glycolysis contribute to the decreased glucose concentrations. Further study is needed to determine whether pharmacologically manipulating HIF expression might be beneficial for treatment of diabetic patients. PMID:23015148

  12. Ghrelin Alleviates MDMA-Induced Disturbance of Serum Glucose and Lipids Levels in the Rat

    Full Text Available Hepatotoxicity is one of the clinically adverse effects of ecstasy (3, 4-methylenedioxymethamphetamine; MDMA consumption. The detoxification tissue, liver, plays a central role in maintaining circulating levels of glucose and lipid. Hypoglycemia and hypotriglyceridemia have been reported due to ecstasy abuse. Ghrelin is a 28-amino-acid peptide secreted predominantly from the stomach. It has been demonstrated that ghrelin has hepatoprotective effects and is able to increase blood glucose concentration. In the current study, we explored the effect of hepatotoxic dose of MDMA and therapeutic use of exogenous ghrelin on the serum levels of glucose and lipids in four groups of rats. MDMA caused a severe and transient reduction in circulating levels of glucose and triglyceride and increased serum LDL. However, cholesterol and HDL levels remained unchanged. Meanwhile, altered hepatic architecture was observed with intracellular vacuolation that may indicate intracellular accumulation of lipid droplets. In addition, following ghrelin administration, the blood sugar levels improved and LDL levels returned to the baseline value, and ghrelin treatment did not improve triglycerides levels. These results showed that MDMA causes hypoglycemia, hypotriglyceridemia, and hyper LDL-cholesterolemia. To our knowledge, this is the first report showing ghrelin administration could improve hypoglycemia and normalize LDL levels induced by MDMA and partially restore hepatic architecture.

    Full Text Available Negative energy balance can impair the metabolism of high producing dairy cows and supplying the glucose, as an energy source; can prevent the metabolic disorders in these animals. Hence, we hypothesized that bolus intravenous glucose administration may change the concentrations of metabolic hormones in order to prevent and control of metabolic dysfunctions of dairy cows. Twenty five multiparous Holstein dairy cows were divided to 5 equal groups containing early, mid and late lactations, far-off and close-up dry periods. All cows were received dextrose 50% intravenously at 500 mg/kg, 10 mL/kg/h. Blood samples were collected from all animals prior to and 1, 2, 3 and 4 after dextrose 50% infusion and sera were separated to determine glucose, triiodothyronine (T3, thyroxine (T4, serum free T3 (fT3, free T4 (fT4, cortisol and insulin like growth factor-1 (IGF-1. The decreasing pattern of T3 concentration was detected in all studied animals following intravenous glucose infusion (P<0.05. The significant increasing pattern of T4 levels was seen in early and mid lactation cows after glucose administration (P<0.05. The significant decreasing pattern of IGF-1 was detected in mid and late lactations and far-off dry groups (P<0.05. There were no significant alterations in fT3, fT4 and cortisol concentrations following glucose infusion in all experimental groups. In conclusion, bolus intravenous glucose infusion could influence the metabolic hormones in high producing Holstein dairy cows. Alterations of metabolic hormones following bolus intravenous glucose administration indicated that glucose is an important direct controller of metabolic interactions and responses in dairy cows during different physiological states.

    The purpose of this study was to evaluate predictors of reduction in ammonia levels by occlusion of portosystemic shunts (PSS) in patients with cirrhosis. Forty-eight patients with cirrhosis (21 women, 27 men; mean age, 67.8 years) with PSS underwent balloon-occluded retrograde transvenous obliteration (BRTO) at one institution between February 2008 and June 2014. The causes of cirrhosis were hepatitis B in one case, hepatitis C in 20 cases, alcohol in 15 cases, nonalcoholic steatohepatitis in eight cases, and other conditions in four cases. The Child-Pugh classes were A in 24 cases, B in 23 cases, and C in one case. The indication for BRTO was gastric varices in 40 cases and hepatic encephalopathy in eight cases. Testing was conducted before and 1 month after the procedure. Statistical analyses were performed to identify predictors of a clinically significant decline in ammonia levels after BRTO. Occlusion of PSS resulted in a clinically significant decrease in ammonia levels accompanied by increased portal venous flow and improved Child-Pugh score. Univariate analyses showed that a reduction in ammonia levels due to BRTO was significantly related to lower plasma glucose levels, higher RBC counts, and higher hemoglobin concentration before the treatment. Furthermore, multivariate logistic regression identified preoperative plasma glucose level as the strongest independent predictor of a significant ammonia reduction in response to BRTO. In addition, although BRTO resulted in significantly declined ammonia levels in patients with normal glucose tolerance before the procedure, ammonia levels were not significantly decreased after shunt occlusion in patients with diabetes mellitus or impaired glucose tolerance before BRTO, according to 75-g oral glucose tolerance test results. Preoperative plasma glucose level is a useful predictor of clinically significant ammonia reduction resulting from occlusion of PSS in patients with cirrhosis. Even if PSS are present, control

    Insulin and leptin resistance are important risk factors for non-alcoholic fatty liver disease (NAFLD). There is limited evidence regarding the effects of turmeric on NAFLD. The aim of this study was to investigate the effects of turmeric supplementation on glycemic status and serum leptin levels in patients with NAFLD. This double-blind randomized controlled clinical trial was conducted on 46 patients with NAFLD (21males and 25 females) aged 20-60 years old and body mass index (BMI) between 24.9 and 40 kg/m2. The turmeric group (n = 23) was given six turmeric capsules daily for 12 weeks. Each capsule contained 500 mg turmeric powder (6×500 mg). The placebo group (n = 23) was given six placebo capsules daily for the same period. Fasting blood samples, anthropometric measurements, and physical activity levels were collected at the baseline and at the end of the study. Daily dietary intakes also were obtained throughout the study. Data were analyzed by independent t test, paired t test and analysis of covariance. Turmeric consumption decreased serum levels of glucose, insulin, HOMA-IR and leptin (by 1.22, 17.69, 19.48 and 21.33% respectively, p Turmeric supplementation improved glucose indexes and serum leptin levels and may be useful in the control of NAFLD complications.

    The effects of guar gum derived from the endosperm of Cyamopsis tetragonoloba (75% soluble fiber, 7.6% insoluble fiber, 2.16% crude protein, 0.78% total lipids, 0.54% ash and 9.55% moisture) on food intake, levels of blood serum cholesterol, triacylglycerols, glucose and LDL and HDL-cholesterol were studied. The effects of guar gum on indices of protein absorption and utilization were also investigated. Diets containing 0%, 10% and 20% (w/w) guar gum or 10% and 20% cellulose powder (reference) were fed to normal rats for 60 days. The rats fed the guar gum diets showed significantly (p Guar gum decreased blood serum glucose only during the first month of the experiment, and no changes in the indices of protein absorption and utilization were found. The guar gum caused a 10% increase in the small intestine length and a 25% retardation in the intestinal transit. The results of this research suggested that guar gum could potentially be effective in the treatment of hypercholesterolemia and obesity in humans.

    In our previous study, fish protein was proven to reduce serum lipids and body fat accumulation by skeletal muscle hypertrophy and enhancing basal energy expenditure in rats. In the present study, we examined the precise effects of fish protein intake on different skeletal muscle fiber types and metabolic gene expression of the muscle. Fish protein increased fast-twitch muscle weight, reduced liver triglycerides and serum glucose levels, compared with the casein diet after 6 or 8 weeks of feeding. Furthermore, fish protein upregulated the gene expressions of a fast-twitch muscle-type marker and a glucose transporter in the muscle. These results suggest that fish protein induces fast-muscle hypertrophy, and the enhancement of basal energy expenditure by muscle hypertrophy and the increase in muscle glucose uptake reduced liver lipids and serum glucose levels. The present results also imply that fish protein intake causes a slow-to-fast shift in muscle fiber type.

    Full Text Available Diabetes mellitus is an important problem amongst human and animals. In veterinary medicine too, diabetes mellitus occurs in many animals particularly household pets. This study was conducted in order to evaluate the effect of date consumption on serumic levels of glucose, triglyceride, cholesterol, LDL, VLDL and HDL in rats suffering from experimental diabetes mellitus. Thirty male wistar rats with the age of 8 weeks and mean body weight of 200±20 gr were selected and divided into 5 groups so that there were 6 rats per group. The groups consisted of day one healthy control, final day healthy control, healthy treatment consuming date, diabetic treatment consuming date and diabetic control group. Diabetic treatment and control groups received 100 mg/kg of alloxan subcutaneously to create experimental diabetes. The two healthy control groups also received equal amounts of normal saline solution subcutaneously. The injections were repeated a week later in all groups. After observing the diabetes symptoms including polydipsia, polyuria, glucosuria and hyperglycemia in groups that were given alloxan, feeding of healthy and diabetic treatment groups with equal ratio of date and pellet was initiated. Final day healthy control group and diabetic control group were fed only with pellet. The groups were fed for 10 days following the start of diabetes symptoms. Blood samples were collected from all groups on day 10. Evaluation of the serumic levels of glucose, cholesterol and LDL revealed statistically significant increase in diabetic control group in comparison with the healthy control groups and also in healthy and  diabetic treatment groups consuming date as compared with diabetic control and healthy groups (p

  20. Fasting plasma glucose and serum uric acid levels in a general Chinese population with normal glucose tolerance: A U-shaped curve.

    Yunyang Wang

    Full Text Available Although several epidemiological studies assessed the relationship between fasting plasma glucose (FPG and serum uric acid (SUA levels, the results were inconsistent. A cross-sectional study was conducted to investigate this relationship in Chinese individuals with normal glucose tolerance.A total of 5,726 women and 5,457 men with normal glucose tolerance were enrolled in the study. All subjects underwent a 75-g oral glucose tolerance test. Generalized additive models and two-piecewise linear regression models were applied to assess the relationship.A U-shaped relationship between FPG and SUA was observed. After adjusting for potential confounders, the inflection points of FPG levels in the curves were 4.6 mmol/L in women and 4.7 mmol/L in men respectively. SUA levels decreased with increasing fasting plasma glucose concentrations before the inflection points (regression coefficient [β] = -36.4, P < 0.001 for women; β = -33.5, P < 0.001 for men, then SUA levels increased (β = 17.8, P < 0.001 for women; β = 13.9, P < 0.001 for men. Additionally, serum insulin levels were positively associated with FPG and SUA (P < 0.05.A U-shaped relationship between FPG and SUA levels existed in Chinese individuals with normal glucose tolerance. The association is partly mediated through serum insulin levels.

  2. Comparison of serum leptin, glucose, total cholesterol and total protein levels in fertile and repeat breeder cows

    Saime Guzel

    2014-12-01

    Full Text Available In the present study we measured serum glucose, leptin, total cholesterol and total protein concentrations in repeat breeder cows and compared them with fertile cows. For this aim, 20 repeat breeder cows and 20 fertile cows were used as material. Repeat breeder cows were found to have lower levels of leptin and glucose as compared with fertile ones. No significant differences in total cholesterol and total protein levels were observed between the two groups. No significant correlation of leptin with glucose, total cholesterol and total protein was observed in fertile and repeat breeder cows. Low concentrations of glucose and leptin can have some effects on reproductive problems as repeat breeder and help to understand potential mechanisms impairing fertility in repeat breeder cows.

    Statin therapy is associated with a slightly increased risk of developing diabetes mellitus and insulin resistance in patients without diabetes. Ezetimibe combined with statins may be considered for high-risk patients who do not achieve optimal low-density lipoprotein cholesterol lowering on statin monotherapy or who are statin intolerant. Changes in fasting serum glucose (FSG) levels during ezetimibe, ezetimibe/statin, and statin treatments were assessed using data pooled from clinical trials in hypercholesterolemic and heterozygous familial hypercholesterolemic patients, who were or were not receiving statin therapy. Study types included first-line trials in statin-naive/wash-out patients and second-line add-on and uptitration studies in patients on stable statin therapy. Similar analyses of FSG changes were performed separately for each study type in patients who were nondiabetic at baseline. Across all study types and treatments, mean FSG increases from baseline were small (0.5 to 3.7 mg/dl with ezetimibe/statin; 0.2 to 4.6 mg/dl with statins) and decreased over time; between-treatment differences (0.3 to 1.4 mg/dl) were nonsignificant for all comparisons. Proportions of patients with elevated FSG ≥126 mg/dl during therapy were low and similar for all treatments in the overall cohort (1.2% to 4.3%). Elevations were highest (3.3% to 25.7%) among patients with baseline factors characteristic of metabolic syndrome and prediabetes, including higher FSG, body mass index, and triglyceride levels, and numerically lower baseline high-density lipoprotein cholesterol; however, these factors were not related to FSG increases. Changes in low-density lipoprotein cholesterol, body mass index, high-density lipoprotein cholesterol, triglycerides, and apolipoprotein B were not significantly correlated with FSG increases. In conclusion, statin therapy was associated with small FSG increases, and the addition of ezetimibe did not further increase FSG levels beyond those of

  4. Study of the Effect of Garlic on Serum Lipids and Blood Glucose Levels in Type 2 Diabetic Patients

    2005-04-01

    Full Text Available Introduction: Hyperlipidemia and diabetes are common risk factors for ischemic heart disease, which is the main cause of mortality in diabetic patients. Strict control of blood glucose and other risk factors in diabetics has led to prevention of complications. Garlic has received particular attention for control of blood glucose and decrease in blood lipid levels. At present, several studies have been carried out in order to prove advantages of garlic. Methods: In this study, effects of garsin (a derivative of garlic present in our country on serum lipids and blood glucose levels in diabetes mellitus type 2 patients was observed. Forty-five type 2 diabetics who had hyperlipidemia were selected. These patients were kept on treatment with 3 tablets of Garsin / day for 4 weeks. Serum lipids and blood glucose levels were measured prior to and at the end of treatment. Results: Relationship between sex and response to treatment in this study was meaningful, such that Gsarsin led to decrease in LDL-C and increase in HDL in females. Conclusion: Therefore, Garsin can be used as an adjunct to treatment in diabetes type 2 patients with hyperlipidemia.

    Galectin-1, a recently identified peptide, is primarily released from the adipose tissue. Although galectin-1 was shown to have an anti-inflammatory effect, its specific function is not clearly understood. We aimed to evaluate the relationship of serum galectin-1 levels with clinical and laboratory parameters in childhood obesity. A total of 45 obese children (mean age: 12.1±3.1years) and 35 normal-weight children (mean age: 11.8±2.2years) were enrolled. Clinical [body mass index (BMI), waist circumference (WC), percentage of body fat and blood pressure] and biochemical [glucose, insulin, lipids, galectin-1, high-sensitive C-reactive protein (hsCRP) and leptin levels] parameters were assessed. Serum galectin-1, hsCRP and leptin levels were significantly higher in obese children than those in normal-weight children (12.4 vs 10.2ng/mL, pobese children, galectin-1 levels correlated negatively with fasting glucose (r=-0.346, p=0.020) and positively with fat mass (r=0.326, p=0.026) and WC standard deviation score (SDS) (r=0.451, p=0.002). The multivariate regression analysis demonstrated that serum galectin-1 levels were significantly associated with fasting glucose and WC SDS. This study showed that obese children had significantly higher galectin-1 levels in proportion to fat mass in obese cases than those in healthy children, which may be interpreted as a compensatory increase in an attempt to improve glucose metabolism.

    Full Text Available Serum concentrations of glucose and Cortisol were measured in five adult captive reindeer (Rangifer tarandus tarandus at 24 h and 10 min before, and at 0.5, 1,2,4, 8, 12 and 24 h after, treatment with 60 p.g/kg of medetomidine i.v. followed by 300 jig/kg of atipamezole i.v. 60 min later. The experiments were performed in January and repeated in July-August. The animals were used as their own controls and treated with saline in July-August. The wash-out period between experiments in summer was 2 weeks or more. No obvious seasonal differences were observed. Mederomidine induced a 2.5-fold increase in glucose (mean ± standard error of the mean being 15.4 ± 0.6 mmol/1 at 1 h and a 3.5-fold increase Cortisol (349 ± 28 nmol/1 at 0.5 h. Serum glucose reached control levels within 12 h, and Cortisol declined to baseline levels within 4 h after injection og medetomidine. The use of blood concentrations of glucose and Cortisol to assess nutritonal status, body condition and stress may be significantly biased in animals chemically immobilized with medetomidine or other alpha-2 adrenoceptor agonists.

    Red palm oil (RPO) is a rich natural source of antioxidant vitamins, namely carotenes, tocopherols and tocotrienols. However, it contains approximately 50 % saturated fatty acids the regular consumption of which could negatively modify lipid profile. The aim of our study was to test whether 7 weeks of RPO supplementation (1 g/kg body weight/day) would affect blood glucose and lipid metabolism in adult male Wistar rats with altered thyroid status. We induced hypothyroidism and hyperthyroidism in rats by oral administration of either methimazole or mixture of thyroid hormones. Different thyroid status (EU - euthyroid, HY - hypothyroid and HT - hyperthyroid) was characterized by different serum thyroid hormones levels (total and free thyroxine and triiodothyronine), changes in the activity of a marker enzyme of thyroid status - liver mitochondrial glycerol-3-phosphate dehydrogenase, and altered absolute and relative heart weights. Fasting blood glucose levels were higher in HT rats in comparison with EU and HY rats, but the changes caused by RPO supplementation were not significant. The achievement of the HY status significantly increased serum levels of total cholesterol, as well as with high-density lipoprotein-cholesterol and low-density lipoprotein-cholesterol: 2.43+/-0.15, 1.48+/-0.09, 0.89+/-0.08 mmol/l, compared to EU: 1.14+/-0.06, 0.77+/-0.06, 0.34+/-0.05 mmol/l and HT: 1.01+/-0.06, 0.69+/-0.04, 0.20+/-0.03 mmol/l, respectively. RPO supplementation did not increase significantly levels of blood lipids but tended to increase glutathione levels in the liver. In conclusion, RPO supplementation did not induce the presumed deterioration of glucose and lipid metabolism in rats with three well-characterized alterations in thyroid status.

    Objective: To study the effect of short-term diabetes on the changes of sexual organ weights and serum levels of testosterone in male rats. Methods: All rats were divided into control (C) and diabetes (D). Diabetes group was observed on 1 day, 3 days, 5 days, 7 days, 14 days after injection of streptozotocin. All rats were killed for measurement of serum levels of glucose, glycosyl protein, testosterone and weights of sexual organs (testis, epididymis, seminal vesicle and prostate). Results: The serum levels of glucose, glycosyl protein of diabetes group decreased significantly, compared with those of control group; the serum levels of T lowered remarkably compared with control levels after three days of injection of STZ. The weight of epididymis, seminal vesicle and prostate reduced remarkably, compared with control group. The weights of seminal vesicle, prostate negatively correlated with serum levels of glucose and glycosyl protein, and they positively correlated with serum levels of testosterone. Conclusion: The sexual organs (testis, epididymis, seminal vesicle and prostate) of male rats with short-term diabetes were damaged, and the changes of sexual organs closely related with the serum levels of testosterone besides irregular metabolism in diabetes

    Current evidence suggests heredity and metabolic syndrome contributes to gout progression. Specifically, the WDR1 and CLNK genes may play a role in gout progression in European ancestry populations. However, no studies have focused on Chinese populations, especially Tibetan individuals. This study aims to determine whether variations in these two genes correlate with gout-related indices in Chinese-Tibetan gout patients. Eleven single-nucleotide polymorphisms in the WDR1 and CLNK genes were detected in 319 Chinese-Tibetan gout patients and 318 controls. We used one-way analysis of variance to evaluate the polymorphisms' effects on gout based on mean serum levels of metabolism indicators, such as albumin, glucose (GLU), triglycerides, cholesterol, high-density lipoproteins (HDL-C), creatinine, and uric acid, from fasting venous blood samples. All p values were Bonferroni corrected. Polymorphisms of the WDR1 and CLNK genes affected multiple risk factors for gout development. Significant differences in serum GLU levels were detected between different genotypic groups with WDRI polymorphisms rs4604059 (p = 0.005) and rs12498927 (p = 0.005). In addition, significant differences in serum HDL-C levels were detected between different genotypic groups with the CLNK polymorphism rs2041215 (p = 0.001). Polymorphisms of CLNK also affected levels of albumin, triglycerides, and creatinine. This study is the first to investigate and identify positive correlations between WDR1 and CLNK gene polymorphisms in Chinese-Tibetan populations. Our findings provide significant evidence for the effect of genetic polymorphisms on gout-related factors in Chinese-Tibetan populations.

    Evidence of characteristics of Japanese patients with diabetes from a large-scale population is necessary. Few studies have compared glycaemic controls, complications and comorbidities between type 1 and 2 diabetic patients. This paper focuses on illustrating a clinical picture of Japanese diabetic patients and comparing glycaemic control and prognoses between type 1 and 2 diabetes using multi-institutional data. The BioBank Japan Project enrolled adult type 1 and 2 diabetic patients between fiscal years 2003 and 2007. We have presented characteristics, controls of serum glucose, cholesterol and blood pressure, prevalence of complications and comorbidities and survival curves. We have also shown glycaemic controls according to various individual profiles of diabetic patients. A total of 558 type 1 diabetic patients and 30,834 type 2 diabetic patients participated in this study. The mean glycated haemoglobin A1c was higher in type 1 diabetes than in type 2 diabetes. In the type 1 diabetic patients, the glycated haemoglobin A1c had no consistent trend according to age and body mass index. The Kaplan-Meier estimates represented a longer survival time from baseline with type 1 diabetes than with type 2 diabetes. Compared with type 1 diabetic patients, type 2 diabetic patients had double the prevalence of macrovascular complications. This work has revealed detailed plasma glucose levels of type 1 and 2 diabetic patients according to age, body mass index, blood pressure, serum cholesterol levels and smoking and drinking habits. Our data have also shown that the prognosis is worse for type 2 diabetes than for type 1 diabetes in Japan. Copyright © 2017 The Authors. Production and hosting by Elsevier B.V. All rights reserved.

    A growing body of evidence suggests that beta-glucan derived from oats or barley can reduce cardiovascular disease risk through reductions in serum lipids. However, the effects of beta-glucan on lipid changes in hypercholesterolemic patient groups are inconsistent. The objective of this study was to identify and quantify the effect of beta-glucan, a marker of water-soluble fiber, on various lipid parameters and glucose level in hypercholesterolemic subjects. We performed a comprehensive literature search to identify the relevant randomized controlled trials (RCTs) that investigated the effects of beta-glucan consumption in hypercholesterolemic subjects. Mean differences (MDs) and 95% confidence intervals (CIs) were calculated for net changes in lipid concentrations by using fixed-effects or random-effects models according to heterogeneity. Publication bias, sensitivity analysis and subgroup analyses were also performed. Seventeen eligible RCTs with 916 subjects were included in the meta-analysis. The pooled result showed that beta-glucan consumption in hypercholesterolemic population significantly lowered the total cholesterol (TC) (MD, -0.26 mmol/L; 95% CI, -0.33 to -0.18; P consumption significantly decreased TC and LDL-cholesterol concentrations but did not affect TG, HDL-cholesterol, and glucose concentrations in hypercholesterolemic subjects.

    Full Text Available Background: Regarding the antioxidant property of Otostegia persica extract and the role of antioxidants in Diabetes mellitus treatment, in this study the effect of extract on serum glucose level and renal function indicators was determined in diabetic male rats. Materials and Methods: Diabetes mellitus (type I was inducted in male rats using intraperitoneal injection of streptozotocin (STZ (65 mg/kg. To determine blood glucose, urea, and creatinine serum levels; fasting blood samples were collected twice (before STZ injection and 5 days later. The rats with their serum glucose level exceeding 250 mg/dl were considered diabetic and divided into 10 groups separately received Otostegia persica alcoholic extract (100, 200, and 300 mg/kg/day doses, glibenclamide with 600 µg/kg dose and 0.5 ml distilled water for 3 and 6 days using gavage. After 3 and 6 days, blood samples were collected again and glucose, urea, and creatinine serum levels were assessed using spectrophotometry technique by respective kits.Results: Treating diabetic rats by Otostegia persica extract (100, 200, and 300 mg/kg/day doses for 6 days results in a significant decrease of glucose and creatinine, yet an increase of serum urea with 200 mg/kg dose. Also, administration of the extract for 3 days (300 mg/kg reduced glucose, and (in various doses urea and creatinine serum levels. Conclusion: Otostegia persica extract has hypoglycemic effect and administering it in diabetes mellitus not only had no undesirable renal side effects, but also improved renal function to some extent.

  15. LX4211 increases serum glucagon-like peptide 1 and peptide YY levels by reducing sodium/glucose cotransporter 1 (SGLT1)-mediated absorption of intestinal glucose.

    LX4211 [(2S,3R,4R,5S,6R)-2-(4-chloro-3-(4-ethoxybenzyl)phenyl)-6-(methylthio)tetrahydro-2H-pyran-3,4,5-triol], a dual sodium/glucose cotransporter 1 (SGLT1) and SGLT2 inhibitor, is thought to decrease both renal glucose reabsorption by inhibiting SGLT2 and intestinal glucose absorption by inhibiting SGLT1. In clinical trials in patients with type 2 diabetes mellitus (T2DM), LX4211 treatment improved glycemic control while increasing circulating levels of glucagon-like peptide 1 (GLP-1) and peptide YY (PYY). To better understand how LX4211 increases GLP-1 and PYY levels, we challenged SGLT1 knockout (-/-) mice, SGLT2-/- mice, and LX4211-treated mice with oral glucose. LX4211-treated mice and SGLT1-/- mice had increased levels of plasma GLP-1, plasma PYY, and intestinal glucose during the 6 hours after a glucose-containing meal, as reflected by area under the curve (AUC) values, whereas SGLT2-/- mice showed no response. LX4211-treated mice and SGLT1-/- mice also had increased GLP-1 AUC values, decreased glucose-dependent insulinotropic polypeptide (GIP) AUC values, and decreased blood glucose excursions during the 6 hours after a challenge with oral glucose alone. However, GLP-1 and GIP levels were not increased in LX4211-treated mice and were decreased in SGLT1-/- mice, 5 minutes after oral glucose, consistent with studies linking decreased intestinal SGLT1 activity with reduced GLP-1 and GIP levels 5 minutes after oral glucose. These data suggest that LX4211 reduces intestinal glucose absorption by inhibiting SGLT1, resulting in net increases in GLP-1 and PYY release and decreases in GIP release and blood glucose excursions. The ability to inhibit both intestinal SGLT1 and renal SGLT2 provides LX4211 with a novel dual mechanism of action for improving glycemic control in patients with T2DM.

    To determine the associations between apolipoprotein E (APOE) genotypes and serum levels of glucose, total cholesterol, and triglycerides in a cognitively normal aging Han Chinese population. There were 1,003 cognitively normal aging subjects included in this study. APOE genotypes were analyzed and biochemical parameters were tested. All the subjects were divided into three groups according to APOE genotypes: (1) E2/2 or E2/3 (APOE E2); (2) E3/3 (APOE E3); and (3) E2/4, E3/4, or E4/4 (APOE E4). Correlations of serum levels of glucose, total cholesterol, and triglycerides with APOE genotypes were assessed. E2, E3, and E4 allele frequencies were found to be 6.2%, 82.1%, and 11.7%, respectively. Serum levels of total cholesterol were higher in the APOE E4 group (Ptriglycerides (adjusted odds ratio 1.042, 95% confidence interval 0.759-1.429, P=0.800). A higher serum level of total cholesterol was significantly correlated with APOE E4 status in a cognitively normal, nondiabetic aging population. However, there was no correlation between APOE genotypes and serum levels of glucose or total triglycerides.

  17. Uric Acid or 1-Methyl Uric Acid in the Urinary Bladder Increases Serum Glucose, Insulin, True Triglyceride, and Total Cholesterol Levels in Wistar Rats

    T. Balasubramanian

    2003-01-01

    Full Text Available In animals deprived of food for a long period, a drop in the fat mass below 5% of the total body mass results in an increase in blood glucocorticoids and uric acid levels, followed by foraging activity. Since the glucocorticoids increase the uric acid excretion, an increase in the level of uric acid in the bladder urine could be the signal for this feeding behaviour and subsequent fat storage. Accumulation of fat is associated with hyperglycaemia, hyperinsulinaemia, hyperlipidaemia, and hypercholesterolaemia as seen in the metabolic syndrome or hibernation. It is hypothesized that uric acid or its structurally related compound, 1-methyl uric acid (one of the metabolites of the methyl xanthines namely caffeine, theophylline, and theobromine present in coffee, tea, cocoa, and some drugs, can act on the urinary bladder mucosa and increases the blood glucose, insulin, triglyceride, and cholesterol levels. In rats, perfusion of the urinary bladder with saturated aqueous solution of uric acid or 1-methyl uric acid results in a significant increase in the serum levels of glucose, insulin, true triglyceride, and total cholesterol in comparison with perfusion of the bladder with distilled water at 20, 40, and 80 min. The uric acid or the 1-methyl uric acid acts on the urinary bladder mucosa and increases the serum glucose, insulin, true triglyceride, and total cholesterol levels.

    The aim of this study was to test whether lower urinary tract symptoms (LUTS) and urinary incontinence are associated with the metabolic syndrome (MetS). The association between LUTS and benign prostatic enlargement (BPE) was also investigated. A cross-sectional, representative risk factor analysis of LUTS, as measured by the International Prostate Symptom Score (IPSS), and urinary incontinence was conducted. Among 950 representative individuals, aged 69-81 years, the association between clinical, anthropometric, endocrine, metabolic and inflammatory factors on the one hand, as both major and minor aspects of MetS, and LUTS and urinary incontinence, on the other hand, was analysed. The prostate gland volume was measured in a subgroup of 155 randomly selected individuals and the association between LUTS and BPE was estimated. No significant association was found between LUTS or urinary incontinence and the major aspects of the MetS. However, in a multivariate analysis, serum serotonin showed an independent negative correlation with LUTS and with urinary incontinence while fasting serum glucose and serum adiponectin showed a positive correlation with LUTS. Furthermore, in a subgroup of 155 individuals, the prostate gland volume correlated positively with LUTS. The study did not show an association between LUTS or urinary incontinence and the major components of the MetS. However, serum serotonin showed an independent negative correlation with LUTS and with urinary incontinence while fasting serum glucose and serum adiponectin showed a positive correlation with LUTS. The data confirm the general knowledge that BPE may be one of the causative factors of LUTS.

    The aim of this study was to investigate the possible correlation between levels of serum liver enzymes and impaired fasting glucose (IFG) in Chinese adults and to provide a new perspective for the prevention of pre-diabetes. Serum liver enzymes of the samples including alanine aminotransferase (ALT), aspartate aminotransferase (AST), and g-glutamyl transferase (GGT), as well as plasma glucose, blood lipids, and insulin, were measured. The cumulative incidences of IFG between different quartiles of liver enzymes were compared by the chi-square test. A logistic regression model (binary regression) was used to calculate the odds ratio (OR) of IFG with 95% confidence interval (95% CI). The total incidence of IFG was 20.3% and the cumulative incidence of IFG was higher in men compared to women. In both sexes, IFG is more prevalent in higher quartiles of liver enzymes. After adjusting for age, BMI, blood pressure, triglycerides (TG), high-density lipoprotein cholesterol (HDL-C), low-density lipoprotein cholesterol (LDL-C), and total cholesterol (TC), the cumulative incidences of IFG were significantly higher in the highest quartiles of liver enzymes than in the lowest quartiles. A significantly higher cumulative incidence of IFG was found in the highest GGT quartile than in the lowest quartile for woman. The results of this study suggest that serum liver enzymes are related to the risk of IFG in Chinese adults. We infer that preserving the hepatic function may be an efficient way to prevent the development of IFG, especially in males.

  20. Glucagon-Like Peptide-1 Secreting Cell Function as well as Production of Inflammatory Reactive Oxygen Species Is Differently Regulated by Glycated Serum and High Levels of Glucose

    Alessandra Puddu

    2014-01-01

    Full Text Available Glucagon-like peptide-1 (GLP-1, an intestinal hormone contributing to glucose homeostasis, is synthesized by proglucagon and secreted from intestinal neuroendocrine cells in response to nutrients. GLP-1 secretion is impaired in type 2 diabetes patients. Here, we aimed at investigating whether diabetic toxic products (glycated serum (GS or high levels of glucose (HG may affect viability, function, and insulin sensitivity of the GLP-1 secreting cell line GLUTag. Cells were cultured for 5 days in presence or absence of different dilutions of GS or HG. GS and HG (alone or in combination increased reactive oxygen species (ROS production and upregulated proglucagon mRNA expression as compared to control medium. Only HG increased total production and release of active GLP-1, while GS alone abrogated secretion of active GLP-1. HG-mediated effects were associated with the increased cell content of the prohormone convertase 1/3 (PC 1/3, while GS alone downregulated this enzyme. HG upregulated Glucokinase (GK and downregulated SYNTHAXIN-1. GS abrogated SYNTHAXIN-1 and SNAP-25. Finally, high doses of GS alone or in combination with HG reduced insulin-mediated IRS-1 phosphorylation. In conclusion, we showed that GS and HG might regulate different pathways of GLP-1 production in diabetes, directly altering the function of neuroendocrine cells secreting this hormone.

    Full Text Available Background: The aim of this study was to determine the effect of two different regimes, containing different carbohydrate to protein ratios on performance, serum glucose and insulin after exercise in soccer players in Tehran; Iran. Methods: Nineteen male soccer players under training [age = 17/5 +/- 1.5 (SE yr] were selected and completed two sequential trials separated by 1 week, in a paired cross-over study design. In each trial, subjects after running to fatigue; received one of three regimes, using a random- order design as follows: HPRO ( CHO 56%, PRO 19% & fat 25% of total energy; HCHO ( CHO 64%, PRO 11% & fat 25% of total energy or control ( CHO 60%, PRO 15% & fat 25% of total energy. The calorie of 3 regimes were equal. After consumption of meal up to120 min, blood was obtained before and at intervals. After 3 hours athlete performance was measured. Results: The study indicates no significant difference in the serum insulin and glucose response among three regimes (P > 0.05. There was no difference in performance between three regimes after 3 h (p > 0.05. Conclusion: The results suggest that post exercise regimes have no influence on performance, serum glucose and serum insulin. Thus total energy content and carbohydrate content may be important in recovery after exercise.

  4. Adiposity associated changes in serum glucose and adiponectin levels modulate ovarian steroidogenesis during delayed embryonic development in the fruit bat, Cynopterus sphinx.

    The aim of the present study was to evaluate the mechanism by which embryonic development in Cynopterus sphinx is impaired during the period of increased accumulation of white adipose tissue during winter scarcity of food. The change in the mass of white adipose tissue during adipogenesis showed significant positive correlation with the circulating glucose level. But increase in circulating glucose level during the adipogenesis showed negative correlation with circulating progesterone and adiponectin levels. The in vivo study showed increased glucose uptake by the adipose tissue during adipogenesis due to increased expression of insulin receptor (IR) and glucose transporter (GLUT) 4 proteins. This study showed decline in the adiponectin level during fat accumulation. In the in vitro study, ovary treated with high doses of glucose showed impaired progesterone synthesis. This is due to decreased glucose uptake mediated decrease in the expression of luteinizing hormone-receptor, steroidogenic acute regulatory protein, IR, GLUT4 and AdipoR1 proteins. But the ovary treated with adiponectin either alone or with higher concentration of glucose showed improvement in progesterone synthesis due to increased expression of IR, GLUT4 and AdipoR1 mediated increased glucose uptake. In conclusion, increased circulating glucose level prior to winter dormancy preferably transported to white adipose tissue for fat accumulation diverting glucose away from the ovary. Consequently the decreased availability of adiponectin and glucose to the ovary and utero-embryonic unit may be responsible for impaired progesterone synthesis and delayed embryonic development. The delayed embryonic development in Cynopterus sphinx may have evolved, in part, as a mechanism to prevent pregnancy loss during the period of decreased energy availability.

    Objectives: To evaluate the hypoglycaemic and anti-platelet aggregation effect of aqueous methanol extract of Acacia Nilotica (AN) leaves compared with glyburide on streptozotocin induced diabetic rats. Methods: Diabetes mellitus was induced in 90 out of 120 albino rats by administering 50 mg/kg body weight (b.w) streptozotocin and was confirmed by measuring fasting blood glucose level >200 mg/dL on fourth post-induction day. The rats were equally divided into 4 groups, A (normal control), B (diabetic control), C (diabetic rats treated with AN extract) and group D (diabetic rats treated with glyburide). The rats of group C and D were given 300 mg/kg b.w AN extract and 900 mu gm/kg b.w glyburide respectively for 3 weeks. Blood glucose was measured by gluco meter, platelet aggregation by Dia-Med method and insulin and b-thrombo globulin by ELISA technique. Results: A significant increase (p<0.05) in fasting blood glucose, b-thrombo globulin and platelet aggregation and a significant decrease (p<0.05) in insulin levels was observed in streptozotocin induced diabetic rats than the normal controls. The rats treated with AN extract and glyburide showed a significant decrease (p<0.05) in fasting blood glucose and increase (p<0.05) in insulin levels than the diabetic control rats. However, the levels in both the treatment groups remained significantly different than the normal controls. A significant decrease (p<0.05) in b-thrombo globulin levels was seen in diabetic rats treated with glyburide than the diabetic control rats and diabetic rats treated with AN extract. Conclusions: AN leaves extract result into hypoglycaemic and anti-platelet aggregation activity in diabetic rats as that of glyburide. (author)

    The brain is dependent on glucose to meet its energy demands. We sought to evaluate the potential importance of impaired glucose transport by assessing the relationship between brain/serum glucose ratios, cerebral metabolic distress, and mortality after severe brain injury. We studied 46 consecutive comatose patients with subarachnoid or intracerebral hemorrhage, traumatic brain injury, or cardiac arrest who underwent cerebral microdialysis and intracranial pressure monitoring. Continuous insulin infusion was used to maintain target serum glucose levels of 80-120 mg/dL (4.4-6.7 mmol/L). General linear models of logistic function utilizing generalized estimating equations were used to relate predictors of cerebral metabolic distress (defined as a lactate/pyruvate ratio [LPR] ≥ 40) and mortality. A total of 5,187 neuromonitoring hours over 300 days were analyzed. Mean serum glucose was 133 mg/dL (7.4 mmol/L). The median brain/serum glucose ratio, calculated hourly, was substantially lower (0.12) than the expected normal ratio of 0.40 (brain 2.0 and serum 5.0 mmol/L). In addition to low cerebral perfusion pressure (P = 0.05) and baseline Glasgow Coma Scale score (P brain/serum glucose ratios below the median of 0.12 were independently associated with an increased risk of metabolic distress (adjusted OR = 1.4 [1.2-1.7], P brain/serum glucose ratios were also independently associated with in-hospital mortality (adjusted OR = 6.7 [1.2-38.9], P brain/serum glucose ratios, consistent with impaired glucose transport across the blood brain barrier, are associated with cerebral metabolic distress and increased mortality after severe brain injury.

    An experimental study was carried out to compare physiological effects (serum glucose level) of medetomidine in Red Sindhi cattle calves at three different doses i.e. 8, 10 and 12µg/kg body weight intravenously. Medetomidine produced a dose dependent significant (P<0.01) increase in serum glucose level with a maximum increase observed at 30 minutes with 8µg/kg, 10μg/kg and 12μg/kg body weight respectively. Start of sedation, degree of sedation and total duration of sedation were all dose dependent and the values obtained were significantly (P<0.01) different from each other. It was observed that the sedation was rapid, deep and longer with the higher doses of medetomidine i.e. 12μg/kg. The results of the present study shows that medetomidine is a very effective and safest drug use as sedative for calves which in lower doses (8μg/kg) can be used as a pre-anesthetic and for restraining of the animal, while higher calculated doses (10μg/kg, 12μg/kg) can be used to execute the minor surgical procedures.

    Cardiovascular, respiratory, and cerebrovascular diseases and malignancies are responsible for morbidity and mortality in acromegaly. Also these diseases are associated with chronic inflammation. The neutrophil to lymphocyte ratio (NLR) and platelet to lymphocyte ratio (PLR) are currently gaining interest as new markers of inflammation. Moreover, increased morbidity and mortality are positively correlated with the presence of diabetes and levels of insulin-like growth factor 1 (IGF-1) in acromegaly. The objective of the present study was to investigate the relationship between these markers and acromegaly according to plasma glucose status and serum IGF-1 levels. We retrospectively analyzed data from 61 acromegaly patients who were in a newly diagnosed period (35 male, 26 female; mean age 38.13 ± 13.98). Patients with normal plasma glucose (n = 27), impaired fasting glucose (n = 18), and diabetes mellitus (n = 16) were categorized into three different groups. NLR and PLR were compared between the study groups and were evaluated according to IGF-1 levels. There were no statistically significant differences in NLR and PLR measurements among the study groups (p > 0.05). However, there were significant positive correlations between NLR and IGF-1 levels and between PLR and IGF-1 levels when all patients were evaluated (r = 0.334, p = 0.011 and r = 0.277, p = 0.035, respectively). This is the first report studying the relationship of NLR and PLR with glucose status and IGF-1 levels in acromegaly patients. Our study results suggest that subclinical inflammation may play a role in increased incidence of mortality and morbidity, which depends on uncontrolled IGF-1 levels in patients with acromegaly. © The Author(s) 2015.

    The inverse relationship between 25-hydroxyvitamin D [25(OH)D] status and insulin resistance (IR) has been reported, but many interventional studies failed to reduce IR with 25(OH)D supplementation. In addition, there has been a paucity of literature on the interaction between 25(OH)D status and IR according to the degree of obesity in Asian subjects. We therefore evaluated the association between 25(OH)D status and IR according to the degree of obesity. Data from the Korea National Health and Nutrition Examination Survey in 2008-2010 were analyzed. The study subjects comprised 10,629 participants aged ≥20 years with fasting glucoseobesity in an adult Korean population without increased fasting glucose levels. We suggest that proper supplementation of vitamin D might be beneficial in obese Korean adults.

    2015-11-01

    Full Text Available Objective(s: Leptin exerts various effects on appetite and body weight. Disruption of the obesitygene is precedent to fatness. Insulin or glucose elevates leptin, but streptozotocin reduces it. However, controversial data exist for the effects of leptin on diabetes and leptin level in each gender. Leptin can damage the kidney function but little evidence exists for its hepatic effects. The aim of this study was to investigate the probable sex-dependent differences in blood sugar levels, lipid profile, and renal and hepatic biochemical factors in the obesity and streptozotocin-induced diabetic rats after leptin administration. Materials and Methods: Wistar rats of both sexes were randomly divided into two groups, namely obese and diabetic rats. Each group was further divided into male and female subgroups. Extra fat and carbohydrate was added to the diet to induce obesity. Furthermore, streptozotocin (55 mg/kg, IP was injected to induce diabetes. The treatment groups received leptin (0.1 mg/kg SC for 10 days, and then, blood samples were taken from the orbital sinus for laboratory evaluations. Results: Leptin resulted in a significant weight loss in both sexes (P

  17. Why control blood glucose levels?

    Rossini, A A

    1976-03-01

    The controversy as to the relationship between the degree of control of diabetes and the progression of the complications of the disease has not been solved. However, in this review, various studies suggesting a relationship between the metabolic abnormality and the diabetic complications are examined. The disadvantages of the uncontrolled diabetes mellitus can be divided into two major categories-short-term and long-term. The short-term disadvantages of controlled diabetes mellitus include the following: (1) ketoacidosis and hyperosmolar coma; (2) intracellular dehydration; (3) electrolyte imbalance; (4) decreased phagocytosis; (5) immunologic and lymphocyte activity; (6) impairment of wound healing; and (7) abnormality of lipids. The long-term disadvantages of uncontrolled diabetes melitus include the following: (1) nephropathy; (2) neuropathy; (3) retinopathy; (4) cataract formation; (5) effect on perinatal mortality; (6) complications of vascular disease; and (7) the evaluation of various clinical studies suggesting the relationship of elevated blood glucose levels and complications of diabetes mellitus. It is suggested that until the question of control can absolutely be resolved, the recommendation is that the blood glucose levels should be controlled as close to the normal as possible.

    2010-01-01

    To compare serum zinc level between Thalassemia Major (TM) patients and normal population at Shafa Hospital in South West of Iran. A total of 25 male and 36 female of TM patients were enrolled in this study. Out of 61 patients thirty were treated by deferroxamine (DFO) and 31 were on the combination of DFO and deferiprone (DEF) protocol therapy. Sixty normal subjects of the matching age and gender were recruited as controls. From each patient and control group 2 ml of blood was taken in fasting condition. Cell blood count and serum zinc were carried out for both thalassemia patients and normal subjects. The mean age of patients and control group was 15+- 5 years. Mean serum zinc level was 68.97+- 21.12 mu g/dl, 78.10-28.50 mu g/dl, and 80.16+- 26.54 mu g/dl in the TM with DFO, TM with DFO + DEF combination protocol and control group respectively. There was no significant correlation between patients and control group. However 50 percent of TM with DFO, 38.7 percent of TM with DFO + DEF and 32.8 percent of control group had hypozincemia. Nearly 40 to 50 percent of TM patients and one third of normal subjects are suffering from hypozincemia. This study shows that low level of serum zinc is a health problem in both thalassemia patients and normal population in South West of Iran. (author)

    Objectives To quantitate and compare the associations of various body composition measurements with serum metabolites and to what degree genetic or environmental factors affect obesity-metabolite relation. Methods Body mass index (BMI), waist circumference (WC), lean body mass (LBM), percent body fat (PBF), fasting serum high density lipoprotein cholesterol (HDL-C), low density lipoprotein cholesterol (LDL-C), triglycerides (TG), total cholesterol (TC), glucose, insulin and lifestyle factors were assessed in 903 twins from Chinese National Twin Registry (CNTR). Homeostasis model assessment of insulin resistance (HOMA-IR) was calculated from fasting serum glucose and insulin. Linear regression models and bivariate structural equation models were used to examine the relation of various body composition measurements with serum metabolite levels and genetic/environmental influences on these associations, respectively. Results At individual level, adiposity measurements (BMI, WC and PBF) showed significant associations with serum metabolite concentrations in both sexes and the associations still existed in male twins when using within-MZ twin pair comparison analyses. Associations of BMI with TG, insulin and HOMA-IR were significantly stronger in male twins compared to female twins (BMI-by-sex interaction p = 0.043, 0.020 and 0.019, respectively). Comparison of various adiposity measurements with levels of serum metabolites revealed that WC explained the largest fraction of variance in serum LDL-C, TG, TC and glucose concentrations while BMI performed best in explaining variance in serum HDL-C, insulin and HOMA-IR levels. Of these phenotypic correlations, 64–81% were attributed to genetic factors, whereas 19–36% were attributed to unique environmental factors. Conclusions We observed different associations between adiposity and serum metabolite profile and demonstrated that WC and BMI explained the largest fraction of variance in serum lipid profile and insulin

    Inflammatory markers are elevated in insulin resistance (IR) and diabetes. We tested whether serum orosomucoid (ORM) is associated with postload glucose, β-cell dysfunction and IR inferred from plasma insulin kinetics during a 75 g oral glucose tolerance test (OGTT). 75 g OGTTs were performed with multiple postload glucose and insulin measurements over a 30-120 min period in 168 non-obese Japanese women (aged 18-24 years). OGTT responses, serum adiponectin and high-sensitivity C reactive protein (hsCRP) were cross-sectionally analyzed by analysis of variance and then Bonferroni's multiple comparison procedure. Stepwise multivariate linear regression analyses were used to identify most important determinants of ORM. Of 168 women, 161 had normal glucose tolerance. Postload glucose levels and the area under the glucose curve (AUCg) increased in a stepwise fashion from the first through the third ORM tertile. In contrast, there was no or modest, if any, association with fat mass index, trunk/leg fat ratio, adiponectin, hsCRP, postload insulinemia, the Matsuda index and homeostasis model assessment IR. In multivariable models, which incorporated the insulinogenic index, the Matsuda index and HOMA-IR, 30 min glucose (standardized β: 0.517) and AUCg (standardized β: 0.495) explained 92.8% of ORM variations. Elevated circulating orosomucoid was associated with elevated 30 min glucose and glucose excursion in non-obese young Japanese women independently of adiposity, IR, insulin secretion, adiponectin and other investigated markers of inflammation. Although further research is needed, these results may suggest a clue to identify novel pathways that may have utility in monitoring dysglycemia within normal glucose tolerance.

    2016-01-01

    Full Text Available Introduction: Gestational diabetes mellitus (GDM is defined as any degree of glucose intolerance with onset or first recognition during pregnancy.[1] Pregnancy is a unique situation in which there is a physiological temporary increase in insulin resistance (IR. The mechanisms responsible for the gestational-induced IR are not completely understood. The current study was undertaken to compare adiponectin levels during 24–28 weeks period of gestation in drug-naive newly diagnosed GDM women with a cohort of normoglycemic pregnant women. Subjects and Methods: A total of 47 pregnant women in the age group of 18–40 years were included in this cross-sectional study, of which 13 were GDM cases and 34 were normoglycemic controls. Serum adiponectin level was analyzed by enzyme-linked immunosorbent assay. Results: The mean adiponectin level was 16.92 ng/ml (standard deviation [SD] = 2.78 and 19.38 ng/ml (SD = 2.71 in case and control groups, respectively, and the difference was found to be statistically significant (P = 0.008. Conclusion: Our study demonstrated decreased serum adiponectin levels in women with GDM when compared with age- and body mass index-matched euglycemic pregnant women.

  5. Serum zinc levels in gestational diabetes

    Full Text Available "nBackground: Maternal zinc deficiency during pregnancy has been related to adverse pregnancy outcomes. Most studies in which pregnant women have been supplemented with zinc to examine its effects on the outcome of the pregnancy have been carried out in industrialized countries and the results have been inconclusive. It has been shown that women with gestational diabetes (GDM have lower serum zinc levels than healthy pregnant women, and higher rates of macrosomia. Zinc is required for normal glucose metabolism, and strengthens the insulin-induced transportation of glucose into cells by its effect on the insulin signaling pathway. The purpose of this study was to assess the serum zinc levels of GDM patients and evaluate the effect of zinc supplementation. "nMethods: In the first stage of this prospective controlled study, we enrolled 70 women who were 24-28 weeks pregnant at the Prenatal Care Center of Mirza Kochak Khan Hospital, Tehran, Iran. The serum zinc level of each subject was determined. In the second stage, among these 70 subjects, the diabetics receiving insulin were divided into two groups, only one of which received a zinc supplement and the other group was the control group. Birth weight of neonates and insulin dosages were recorded. "nResults: The mean serum zinc level in the GDM group was lower than that of the control group (94.83 vs. 103.49mg/dl, respectively and the mean birth weight of neonates from the GDM women who received the zinc supplement was lower than that of the control group (3849g vs. 4136g. The rate of macrosomia was lower in the zinc supplemented group (20% vs. 53%. The mean of increase of insulin after receiving the zinc supplement was lower (8.4u vs. 13.53.

    Full Text Available Abstract   Background & aim: Lipid metabolism disorder plays an important role in insulin resistance in skeletal muscle and lipid drop proteins such as perlipine 2 (PLIN2 are effective in regulating intracellular fat metabolism. One of the suggested pathways for the effects of endurance activity in metabolic diseases is the effect of physical activity on intramuscular. Therefore, the purpose of this study was compare the intensity of aerobic exercise intensity (low intensity and high intensity on expression of PLIN2 skeletal muscle, serum glucose and insulin levels in streptozotocin-diabetic rats.   Methods: In this experimental study, 24 male Wistar rats were randomly divided into three groups of 8, including two intervention groups (low intensity endurance training group and high intensity continuous exercise group and one control group. After induction of diabetic rats by injection streptozotocin (55 mg / kg body weight, Intraperitoneally, endurance training was applied for eight weeks, three sessions per week in diabetic rats. Exercise intensity in the low-intensity group was equal to 5-8 m / min (equivalent to 50-60% Vo2max, the intensity of training in a high intensity training group was equivalent to a speed of 22-25 m / min (equivalent to 80% Vo2max and the control group did not receive intervene in this time. Relative protein expression of PLIN2 was performed using western blot technique. Data were analyzed by one-way ANOVA and Tukey's post hoc test.   Results: The results of the intergroup comparison revealed a significant difference among three groups in the PLIN2 variables (p = 0.037. The results of post hoc test showed a significant increase in PLIN2 in high intensity training diabetic group compared to the control group (p = 0.033 However, there was no significant difference in PLIN2 level in the low exercise group compared to the control group (p = 0.18. Also, there was no significant difference between the low intensity and

    The complex changes in serum LH and FSH levels from infancy to adulthood are diversely evaluated by radioimmunoassays or bioassays. The relative lack of sensitivity and specificity of radioimmunoassay, using polyclonal antibodies, could possibly be overcome by new immunoradiometric assays, using specific antibodies to LH and FSH. Significant differences were indeed observed between radioimmunoassays and immunoradiometric assays. During the prepubertal period, LH levels, measured by the immunoradiometric assays, were below the sensitivity of the method in the majority of the samples. LH levels were, however, well detectable when measured with radioimmunoassay, showing the heterogeneity of circulating LH structures. At the onset of puberty, LH levels increased at least 3 to 4 times in both sexes, when measured with immunoradiometric assays, whereas their increase was only 20 to 60% with the radioimmunoassays. FSH levels remained well detectable in the prepubertal period whether measured by immunoradiometric or radioimmunoassays. At pubertal onset, FSH increase in both sexes was more important in the immunoradiometric assays. The results obtained with immunoradiometric assays give a better insight into the quantitative and qualitative function of the gonadotropes during childhood. The almost complete absence of LH during the prepubertal period and the steep increase at the onset of puberty better reflects the reported data obtained with bioassays. The persistance of significant levels of FSH in the prepubertal ages, and the lesser increase at the onset of puberty, when compared with LH, illustrates that the individual regulation of LH and FSH secretion vary over time and is influenced by developmental factors.

    2016-06-01

    Full Text Available Diabetes Mellitus (DM is a syndrome in metabolism of carbohydrates which indicated by the increased level of blood glucose and also may increase salivary glucose levels. Oral ulcer has been frequently recognized in diabetic patients, which can be due to increased glucose in oral fluids and immune dysfunction. This study aimed to determine the correlation of blood glucose levels and salivary glucose levels with oral ulcer in diabetic patients. Analytic observational study was carried out through the determination of blood glucose levels just by way of strip using a glucometer and salivary glucose levels with the method "GOD-PAP test enzymatic colorimetric". Oral ulcer was determined in presenting ulcer on 30 patients with DM. The results showed r = 0.228, which is higher salivary glucose levels followed by high levels of blood glucose, and intraoral examination of oral ulcer found in the whole sample and the most location commonly found in buccal mucosa and lingual. It was concluded that there is a correlation between blood glucose levels and salivary glucose levels, and glucose levels affect the occurrence of oral ulcer in patients with DM

    This study aimed to investigate whether the previously described differentiating islet-like aggregates of human pancreatic adenocarcinoma cells (PANC-1) develop glucose response and exhibit intercellular communication. Fura 2-loaded PANC-1 cells in serum-free medium were assayed for changes in cytosolic free calcium ([Ca]i) induced by depolarization, tolbutamide inhibition of K(ATP) channels, or glucose. Dye transfer, assayed by confocal microscopy or by FACS, was used to detect intercellular communication. Changes in messenger RNA (mRNA) expression of genes of interest were assessed by quantitative real-time polymerase chain reaction. Proliferation was assayed by the MTT method. Serum-deprived PANC-1 cell aggregates developed [Ca]i response to KCl, tolbutamide, or glucose. These responses were accompanied by 5-fold increase in glucokinase mRNA level and, to a lesser extent, of mRNAs for K(ATP) and L-type calcium channels, as well as increase in mRNA levels of glucagon and somatostatin. Trypsin, a proteinase-activated receptor 2 agonist previously shown to enhance aggregation, modestly improved [Ca]i response to glucose. Glucose-induced coordinated [Ca]i oscillations and dye transfer demonstrated the emergence of intercellular communication. These findings suggest that PANC-1 cells, a pancreatic adenocarcinoma cell line, can be induced to express a differentiated phenotype in which cells exhibit response to glucose and form a functional syncytium similar to those observed in pancreatic islets.

    2017-10-01

    Background: Although insulin may increase the risk of some cancers, few studies have examined fasting serum insulin and lung cancer risk. Methods: We examined serum insulin, glucose, and indices of insulin resistance [insulin:glucose molar ratio and homeostasis model assessment of insulin resistance (HOMA-IR)] and lung cancer risk using a case-cohort study within the Alpha-Tocopherol, Beta-Carotene Cancer Prevention Study of Finnish men. A total of 196 cases and 395 subcohort members were included. Insulin and glucose were measured in fasting serum collected 5 to 12 years before diagnosis. Cox proportional hazards models were utilized to estimate the relative risk of lung cancer. Results: The average time between blood collection and lung cancer was 9.6 years. Fasting serum insulin levels were 8.7% higher in subcohort members than cases. After multivariable adjustment, men in the fourth quartile of insulin had a significantly higher risk of lung cancer than those in the first quartile [HR = 2.10; 95% confidence interval (CI), 1.12-3.94]. A similar relationship was seen with HOMA-IR (HR = 1.83; 95% CI, 0.99-3.38). Risk was not strongly associated with glucose or the insulin:glucose molar ratio ( P trend = 0.55 and P trend = 0.27, respectively). Conclusions: Higher fasting serum insulin concentrations, as well as the presence of insulin resistance, appear to be associated with an elevated risk of lung cancer development. Impact: Although insulin is hypothesized to increase risk of some cancers, insulin and lung cancer remain understudied. Higher insulin levels and insulin resistance were associated with increased lung cancer risk. Although smoking cessation is the best method of lung cancer prevention, other lifestyle changes that affect insulin concentrations and sensitivity may reduce lung cancer risk.

    Overnight fasted male rats of Wistar strain were irradiated with single whole-body doses of 4.78-7.17-9.57 and 14.35 Gy of gamma rays. After decapitation at intervals 1-28 d (4.78 and 7.17 Gy), 1-7 d (9.57 Gy) and 1-3 d (14.35 Gy) glucose concentration in serum and glycogen concentration in liver of irradiated and non-irradiated animals were determined. The higher was radiation dose the more expressive extent and depth of changes (hyperglycemia, accumulation of glycogen) occured. Blood glucose and liver glycogen may serve as a reliable and dose-dependent biological indicators of metabolic changes in irradiated rats. (author)

    Androgens and insulin may contribute to increased sebum production in the pathogenesis of acne vulgaris. We investigated the association between serum desnutrin levels and acne vulgaris in the pathogenesis of insulin resistance. 25 patients presenting with acne vulgaris and 25 control subjects participated in this study. Fasting blood glucose, triglycerides, LDL, VLDL, HDL, total cholesterol, insulin, C-peptide and thyroid function tests were measured. The homeostasis model assessment of insulin resistance (HOMA-IR) was used to calculate insulin resistance. Desnutrin levels were determined by enzyme-linked immunosorbent assay (ELISA) according to the manufacturer's protocol. Patients with acne vulgaris had a mean serum desnutrin level of (8.83 ± 1.13 μIU/mL), which was statistically significantly lower in the control group (10:58 ± 3.43 μIU/mL). In patients with acne vulgaris the serum glucose levels, insulin levels and HOMA-IR values (87.92 ± 7:46 mg/dL, 11.33 ± 5.93 μIU/mL, 2.49 ± 1.40, respectively) were significantly higher than the control group (77.36 ± 9.83 mg/dL, 5.82 ± 2.68 μIU/mL, 1.11 ± 0.51, respectively) (p = 0.01, pacne vulgaris, as a result of increased levels of serum glucose and insulin, the function of desnutrin was suppressed, perhaps contributing to insulin resistance.

    Abstract Follistatin is a glycoprotein with various biologic functions that plays a role in adipocyte differentiation, muscle stimulation, anti-inflammation, and energy homeostasis. Thyroid hormones influence energy expenditure, glucose, and lipid metabolism. The association between serum follistatin level and thyroid function statuses has seldom been evaluated. The objectives of this study were to compare serum follistatin concentrations in different thyroid function statuses and to evaluate the associations between serum follistatin and free thyroxine (fT4) levels. In this study, 30 patients with hyperthyroidism (HY group) and 30 euthyroid individuals (EU group) were recruited. The patients of HY group were treated with antithyroid regimens as clinically indicated, whereas no medication was given to EU group. The demographic and anthropometric characteristics, biochemical data, serum levels of follistatin, and thyroid function of both groups at baseline and at the 6th month were compared. Data of all patients were pooled for the analysis of the associations between the levels of follistatin and fT4. At baseline, the HY group had significantly higher serum follistatin levels than the EU group (median [Q1, Q3]: 1.81 [1.33, 2.78] vs 1.13 [0.39, 1.45] ng/mL, P hyperthyroidism had higher serum follistatin levels, which decreased after receiving antithyroid treatment. In addition, the serum follistatin concentrations were positively associated with serum fT4 levels in patients with hyperthyroidism or euthyroidism. PMID:26844494

    2010-01-01

    Full Text Available OBJECTIVE: The level of hemoglobin A1c (HbA1c, also known as glycated hemoglobin, determines how well a patient's blood glucose level has been controlled over the previous 8-12 weeks. HbA1c levels help patients and doctors understand whether a particular diabetes treatment is working and whether adjustments need to be made to the treatment. Because the HbA1c level is a marker of blood glucose for the previous 120 days, average blood glucose levels can be estimated using HbA1c levels. Our aim in the present study was to investigate the relationship between estimated average glucose levels, as calculated by HbA1c levels, and fasting plasma glucose levels. METHODS: The fasting plasma glucose levels of 3891 diabetic patient samples (1497 male, 2394 female were obtained from the laboratory information system used for HbA1c testing by the Department of Internal Medicine at the Izmir Bozyaka Training and Research Hospital in Turkey. These samples were selected from patient samples that had hemoglobin levels between 12 and 16 g/dL. The estimated glucose levels were calculated using the following formula: 28.7 x HbA1c - 46.7. Glucose and HbA1c levels were determined using hexokinase and high performance liquid chromatography (HPLC methods, respectively. RESULTS: A strong positive correlation between fasting plasma glucose levels and estimated average blood glucose levels (r=0.757, p<0.05 was observed. The difference was statistically significant. CONCLUSION: Reporting the estimated average glucose level together with the HbA1c level is believed to assist patients and doctors determine the effectiveness of blood glucose control measures.

    Preferential expression of oncofetal extra domain-B fibronectin (EDB + FN), a proposed angiogenic marker, has been shown in proliferative diabetic retinopathy. High levels of glucose also increase EDB + FN expression in endothelial cells (ECs) via transforming growth factor-β1 (TGF-β1) and endothelin-1 (ET-1). The present study was aimed at elucidating the role of serum- and glucocorticoid-regulated kinase (SGK-1) in glucose-induced EDB + FN expression. Using human macro- and microvascular ECs, we show that high levels of glucose, TGF-β1, and ET-1 increase the EDB + FN expression via SGK-1 alteration at the mRNA, protein, and activity levels. Inhibition of TGF-β1 and ET-1 prevented glucose-induced SGK-1 activation and the EDB + FN expression. Furthermore, using siRNA-mediated SGK-1 gene silencing, we show that glucose-induced EDB + FN expression can be completely prevented. These findings provide first evidence of glucose-induced SGK-1 activation in altered EDB + FN expression and provide novel avenues for therapeutic modalities

    Full Text Available Objectives: There is alarming rise in number of people with diabetes mellitus over these years. If glucose in saliva is linked to glucose in blood it can be used to detect diabetes mellitus at an early stage. The present study is undertaken with the aim to assess the correlation of salivary glucose level with blood glucose level in people with diabetes mellitus. Material and Methods: For investigations, 2 sets of samples of people with diabetes and the age and sex matched non-diabetic subjects were recruited. The salivary glucose was analyzed in unstimulated whole saliva samples using glucose oxidase method. Pearson’s correlation coefficient test was applied to assess the correlation between salivary glucose level and blood glucose level. Results: The significant (P < 0.05 positive correlation of salivary glucose level and fasting blood glucose level was observed in people with uncontrolled diabetes in both the sets of samples.Conclusions: Although study suggests some potential for saliva as a marker in monitoring of diabetes mellitus, there are many aspects that need clarification before we reach to a conclusion.

    Glycated hemoglobin (HbA1c) is widely used as a marker of glycemic control. Translation of the HbA1c level to an average blood glucose level is useful because the latter figure is easily understood by patients. We studied the association between blood glucose levels revealed by the oral glucose tolerance test (OGTT) and HbA1c levels in a Korean population. A total of 1,000 subjects aged 30 to 64 years from the Cardiovascular and Metabolic Diseases Etiology Research Center cohort were included. Fasting glucose levels, post-load glucose levels at 30, 60, and 120 minutes into the OGTT, and HbA1c levels were measured. Linear regression of HbA1c with mean blood glucose levels derived using the OGTT revealed a significant correlation between these measures (predicted mean glucose [mg/dL] = 49.4 × HbA1c [%] - 149.6; R (2) = 0.54, p Glucose (ADAG) study and Diabetes Control and Complications Trial (DCCT) cohort. Discrepancies between our results and those of the ADAG study and DCCT cohort may be attributable to differences in the test methods used and the extent of insulin secretion. More studies are needed to evaluate the association between HbA1c and self monitoring blood glucose levels.

    Full Text Available The purpose of the investigation was to determine the umbilical cord venous blood level of glucose in full-term newborns and its relationship to the mode of delivery. The investigation included 102 full-term newborn infants, including 33 and 69 babies born via cesar-ean and vaginal delivery, respectively. Umbilical cord serum glucose levels were determined by the glucose oxidase test using a Sap-phire-400 biochemical analyzer. In healthy full-term newborns, the mean umbilical cord blood glucose levels were 4,29±0,88 mmol/1 (minimum, 2,9 mmol/1 and maximum, 5,9 mmol/1. In the babies born via cesarean delivery, the umbilical cord blood concentration of glucose was ascertained to be significantly lower than in those born vaginally (3,84+0,71 mmol/1 versus 4,51+0,87 mmol/1; /><0,0001. Abdominal delivery can be apparently considered to be a risk factor for hypoglycemia in neonatal infants.

    Objective: To explore the regulation of changes in serum leptin level in patients with diabetic retinopathy. Methods: The 120 participating subjects were of four groups: healthy controls, diabetic patients without retinopathy, patients with NPDR and patients with PDR, each group consisted of 18 males and 12 females with comparable BMI. The levels of serum leptin, IVC, insulin and blood glucose of these patients were measured and the correlation between serum leptin level and other parameters was analysed. Results: The level of serum leptin in controls, diabetic patients without retinopathy, patients with NPDR and patients with PDR were 6.91 ± 1.87 μg/L, 7,83 ±2.11 μg/L, 9.56 ± 2.43 μg/L and 11.69 ± 2.57 μg/L respectively. The patients with PDR had higher serum leptin levels than patients with NPDR (t=2.15, p < 0.05), diabetic patients without retinopathy (t = 2.71, p < 0.01), and controls (t = 3.50, p < 0.001), the patients with NPDR had higher serum leptin levels than diabetic patients without retinopathy (t = 2.23, p < 0.05) and controls (t = 2.75, p < 0.01), while the difference in serum leptin was not significant between diabetic patients without retinopathy and controls. The serum level was positively correlated to BMI (r = 0.22, p < 0.05) and FINS (r = 0.28, p < 0.01). Conclusion: Serum leptin level is elevated in patients with diabetic retinopathy and is positively correlated to the severity of the disease

    Systemic Sclerosis (SSc) is a systemic connective tissue disease. In this study, we compared the serum Homocystein (Hcy) level between patients with SSc and normal control group. The current study was conducted to determine whether serum Hcy levels are elevated in SSc patients and whether there is any correlation between Hcy levels and RP, Gastro intestinal and lung involvement. Forty one patients who fulfilled the diagnostic criteria for SSc (39 females and 5 males) and Forty four community-based healthy individuals (sex and age matched) were enrolled in to the study. Serum Hcy, vitamin B12, and folate levels were determined. Thirty three patients (70.45%) had GI involvement, twenty two patients (50%) had lung involvement and twenty seven patients (61.36%) had Raynaud's phenomena. Mean serum Hcy level in control group was 22.78 ± 6.018 μmol/L and in case group was 19.43 ± 7.205 μmol/L, shows that the serum Hcy level in control group was significantly higher than patients (P = 0.020). Serum Hcy level is significantly lower in SSc patients than in control group. There is no statistically significant correlation between serum Hcy level and organ involvements.

    Full Text Available Adipokines and ghrelin play role in insulin resistance, the key pathophysiological abnormality in patients with nonalcoholic fatty liver diseases. In the present study, relationship between nonalcoholic steatohepatitis (NASH and serum adipokine and ghrelin levels was investigated. Thirty seven patients with biopsy-proven NASH and 25 age- and sex-matched controls were enrolled. Ten of NASH patients (27% had diabetes mellitus (n=5 or impaired glucose tolerance (n=5. Body mass index (BMI was less than 30 kg/m2 in 67.6% of patients, while in the remaining 32.4% it was more than 30 kg/m2. Serum adiponectin, leptin, TNF-α, and ghrelin were determined. Serum leptin (15.49±4.84 vs 10.31±2.53 and TNF-α (12.1±2.7 vs 10.31±2.56 levels were significantly higher in the NASH group compared to in the control group (P30 or glucose tolerance was impaired or not (P>.05. Additionally, neither adipokines nor ghrelin was correlated with histopathological grade and stage (P>.05. In conclusion; there is a significant relationship between NASH and adipokines and ghrelin independent from BMI and status of the glucose metabolism. These cytokines that appear to have role in the pathogenesis of NASH, however, do not have any effect upon the severity of the histopathology.

  5. Possible Increase in Serum FABP4 Level Despite Adiposity Reduction by Canagliflozin, an SGLT2 Inhibitor.

    Masato Furuhashi

    Full Text Available Fatty acid-binding protein 4 (FABP4/A-FABP/aP2 is secreted from adipocytes in association with catecholamine-induced lipolysis, and elevated serum FABP4 level is associated with obesity, insulin resistance and atherosclerosis. Secreted FABP4 as a novel adipokine leads to insulin resistance via increased hepatic glucose production (HGP. Sodium-glucose cotransporter 2 (SGLT2 inhibitors decrease blood glucose level via increased urinary glucose excretion, though HGP is enhanced. Here we investigated whether canagliflozin, an SGLT2 inhibitor, modulates serum FABP4 level.Canagliflozin (100 mg/day was administered to type 2 diabetic patients (n = 39 for 12 weeks. Serum FABP4 level was measured before and after treatment.At baseline, serum FABP4 level was correlated with adiposity, renal dysfunction and noradrenaline level. Treatment with canagliflozin significantly decreased adiposity and levels of fasting glucose and HbA1c but increased average serum FABP4 level by 10.3% (18.0 ± 1.0 vs. 19.8 ± 1.2 ng/ml, P = 0.008, though elevation of FABP4 level after treatment was observed in 26 (66.7% out of 39 patients. Change in FABP4 level was positively correlated with change in levels of fasting glucose (r = 0.329, P = 0.044, HbA1c (r = 0.329, P = 0.044 and noradrenaline (r = 0.329, P = 0.041 but was not significantly correlated with change in adiposity or other variables.Canagliflozin paradoxically increases serum FABP4 level in some diabetic patients despite amelioration of glucose metabolism and adiposity reduction, possibly via induction of catecholamine-induced lipolysis in adipocytes. Increased FABP4 level by canagliflozin may undermine the improvement of glucose metabolism and might be a possible mechanism of increased HGP by inhibition of SGLT2.UMIN-CTR Clinical Trial UMIN000018151.

    2017-04-01

    To clarify the alterations in serum adropin and preptin concentrations in preeclampsia, we determined serum adropin and preptin levels in 29 women with normal pregnancy and 32 women with preeclampsia. We found that maternal age, body mass index and fetal gender were not significantly different between two groups; however, blood pressure, gestational age and neonatal birth weight were significantly different. Serum adropin levels were significantly increased in women with preeclampsia compared with those with normal pregnancy but there were no significant differences in preptin levels. An increase in maternal serum adropin level was found in preeclampsia, and this may be a compensation for pregnancy complicated with preeclampsia.

  7. Blood glucose level reconstruction as a function of transcapillary glucose transport.

    Koutny, Tomas

    2014-10-01

    A diabetic patient occasionally undergoes a detailed monitoring of their glucose levels. Over the course of a few days, a monitoring system provides a detailed track of their interstitial fluid glucose levels measured in their subcutaneous tissue. A discrepancy in the blood and interstitial fluid glucose levels is unimportant because the blood glucose levels are not measured continuously. Approximately five blood glucose level samples are taken per day, and the interstitial fluid glucose level is usually measured every 5min. An increased frequency of blood glucose level sampling would cause discomfort for the patient; thus, there is a need for methods to estimate blood glucose levels from the glucose levels measured in subcutaneous tissue. The Steil-Rebrin model is widely used to describe the relationship between blood and interstitial fluid glucose dynamics. However, we measured glucose level patterns for which the Steil-Rebrin model does not hold. Therefore, we based our research on a different model that relates present blood and interstitial fluid glucose levels to future interstitial fluid glucose levels. Using this model, we derived an improved model for calculating blood glucose levels. In the experiments conducted, this model outperformed the Steil-Rebrin model while introducing no additional requirements for glucose sample collection. In subcutaneous tissue, 26.71% of the calculated blood glucose levels had absolute values of relative differences from smoothed measured blood glucose levels less than or equal to 5% using the Steil-Rebrin model. However, the same difference interval was encountered in 63.01% of the calculated blood glucose levels using the proposed model. In addition, 79.45% of the levels calculated with the Steil-Rebrin model compared with 95.21% of the levels calculated with the proposed model had 20% difference intervals.

    Khosrowbeygi, A.; Ahmadvand, H.

    2009-01-01

    The results of the serum levels of adiponectin in pre eclamptic patients are conflicting. Objective: The aim of the present study was to assess serum levels of adiponectin in women with pre eclampsia compared with healthy pregnant women. Methods: A cross-sectional study was designed. The case group consisted of women with pre eclampsia (n=30). The control group consisted of 30 matched normal pregnant women. Serum levels of adiponectin were assessed using enzyme-linked immunosorbent assay method. Results: Serum levels of adiponectin were significantly higher in the pre eclamptic group than those in the normal control group. In the pre eclamptic patients serum levels of adiponectin showed a significant negative correlation with body mass index while no correlation was found in the normal pregnant women. In women with pre eclampsia, levels of adiponectin were decreased significantly in the overweight women compared with normal weight women, while in the control group no significant difference was observed. Conclusion: In conclusion, elevation of adiponectin levels might be a physiological feedback response to minimize endothelial dysfunction in pre eclamptic patients. (author)

    Nikolova, K.; Vassileva, D.

    2003-01-01

    Erythropoietin (Epo) is the first well studied hemopoietic growth factor. The pathological levels of its serum concentration show deviations in the specific mechanisms for some diseases such as polycythemia. Objective of this work is the assessment of the diagnostic value of the Epo in the serum for the differentiation of the main form of polycythemia - true and symptomatic. Material and methods: 47 patients are studied (21 women and 26 men), 23 of them are with polycythemia vera and 24 with polycythemia symptomatica. The following has been determined: the serum level of Erythropoietin, hemoglobin, the number of erythrocytes, leukocytes, thrombocytes, myelogram. The serum level of Epo is quantitatively determined b using of radioimmunological method, through Epo-Trac kit. Results: The diagnosis is also confirmed in all patients by other laboratory tests. The normal values of Epo in healthy persons are 17.0±7.0 mU/ml. The average Epo level in patients with polycythemia vera is 20.4±3.0 mU/ml. In one patient the Epo level is supposedly connected with an accompanying kidney disease. Conclusions: The obtained data show that the Epo serum level is an accurate criterion in the diagnosing of true and symptomatic polycythemia. The true polycythemia is connected with an independent erythrocyte production. In the symptomatic polycythemia the tissue hypoxia stimulated the Epo production

    Saliva is a unique fluid, which is important for normal functioning of the oral cavity. Diabetes mellitus (DM) is a disease of absolute or relative insulin deficiency characterized by insufficient secretion of insulin by pancreatic beta-cells. The diagnosis of diabetes through blood is difficult in children, older adults, debilitated and chronically ill patients, so diagnosis by analysis of saliva can be potentially valuable as collection of saliva is noninvasive, easier and technically insensitive, unlike blood. The aim of the study was to correlate blood glucose level (BGL) and salivary glucose level (SGL) in DM patients. A cross-sectional study was conducted in 120 patients, who were categorized as 40 controlled diabetics, 40 uncontrolled diabetics and 40 healthy, age- and sex-matched individuals constituted the controls. The blood and unstimulated saliva samples were collected from the patients at the different intervals for fasting, random and postprandial levels. These samples were then subjected for analysis of glucose in blood and saliva using glucose oxidase/peroxidase reagent in HITACHI 902 (R) Automatic analyzer, and the results were recorded. The mean SGLs were higher in uncontrolled and controlled diabetic groups than in nondiabetic group. A highly statistically significant correlation was found between fasting saliva glucose and fasting blood glucose in all the groups. With increase in BGL, increase in SGL was observed in patients with diabetes suggesting that SGL can be used for monitoring glycemic level in DM.

    The aim of the study is to evaluate work-related subjective stress in a group of workers on a major Italian company in the field of healthcare through the administration of a valid "questionnaire-tool indicator" (HSE Indicator Tool), and to analyze any correlation between stress levels taken from questionnaire scores and blood glucose values. We studied a final sample consisting of 241 subjects with different tasks. The HSE questionnaire - made up of 35 items (divided into 7 organizational dimensions) with 5 possible answers - has been distributed to all the subjects in occasion of the health surveillance examinations provided by law. The questionnaire was then analyzed using its specific software to process the results related to the 7 dimensions. These results were compared using the Pearson correlation and multiple linear regression with the blood glucose values obtained from each subject. From the analysis of the data the following areas resulted critical, in other words linked to an intermediate (yellow area) or high (red area) condition of stress: sustain from managers, sustain from colleagues, quality of relationships and professional changes. A significant positive correlation (p work stress can be statistically associated with increased levels of blood glucose.

    Serum zinc level amongst children with protein energy malnutrition (PEM) was evaluated in a control study conducted in the Department of Paediatrics, Allama Iqbal Medical College and Jinnah Hospital, Lahore. Twenty-five children with PEM and 25 healthy children as control from the community were screened. Mean serum zinc level was found to be 54.48 -+ 18.91 mg/dl in children with PEM while it was 72.72 -+ 8.21 mg/dl in control group (P < 0.001). No significant difference in zinc level was noted between both sexes in each group. Marasmic 16 children revealed mean serum zinc level of 57.55 -+ 18.16 mg/dl while in Kwashiorkor it was 44.57 -+ 13.66 mg/dl. Serum zinc was significantly low in Kwashiorkor than in marasmus (P < 0.001). It was also significantly low in children with acute or chronic diarrhea associated with malnutrition (44.66 -+ 16.0 mg/dl). Acute respiratory infections in these children were not associated with low serum zinc level (71.66 -+ 16.51 mg/dl). (author)

    Sun Shuhong; Yu Hua; Niu Airong; Wu Yuqing

    2006-01-01

    To evaluate changes of serum leptin levels in patients with viral hepatitis C(HCV), serum leptin levels were determined by RIA in 65 patients with viral chronic hepatitis C and in 80 control subjects ,liver function (ALT, AST) , glucose (Glu) , and total cholesterol (TC) were evaluated too. Campared with controls, the levels of serum leptin were significantly increased in patients with HCV (P 0.05). The levels of serum leptin increased in patients with HCV, which correlates positively with the severity of liver inflammation, so that leptin can be regarded as an index which reflects the severity of liver inflammation.

  18. Serum erythropoietin levels by radioimmunoassay in polycythaemia

    Birgegaard, G.; Miller, O.; Caro, J.; Erslev, A. (Cardeza Foundation for Hematological Research, Jefferson University, Philadelphia, Pa.)

    1982-01-01

    A radioimmunoassay (RIA) method for erythropoietin (Epo) was developed and validated against the polycythaemic mouse assay. The correlation was good, with a r=0.94. Several other criteria of specificity were also filled by the RIA, which had a lower detection limit of 5 mU/ml. The mean serum-Epo level in 6 patients with secondary polycythaemia, 50.2 +- 26.2 mU/ml, was significantly higher than in a group of 11 normal subjects, 28.7 +- 7.2 mU/ml (P<0.0002). However, the Epo level in 31 polycythaemia vera (PV) patients, M = 21.9 +- 6.6 mU/ml, was not significantly different from normal (P = 0.006). Since previous studies with bioassay of heat-treated and concentrated plasma samples have shown a decreased serum-Epo level in PV, Epo levels were measured before and after heat treatment and concentration of samples from normals and polycythaemics. It was found that the levels of immunoreactive material increased after heat treatment and 40 times concentration in samples from normals and patients with secondary polycythaemias, but decreased in PV. We conclude that the Epo levels in serum in the low range measured by our and previous RIA:s probably are not true Epo levels but are partly due to an unspecific serum effect, that was removed by heat treatment.

  20. Serum prolactin level in patients taking olanzapine

    Diganta Das

    2015-01-01

    Full Text Available Introduction: Olanzapine is a commonly used antipsychotic. Prolactin elevation is a common adverse effect of anstipsychotics, and serum prolactin elevation is seen in about 30% patients treated with olanzapine. There are confounding results about dose dependency of olanzapine and prolactin elevation, and also the duration of treatment. Method: Fifty six patients, 36 male and 20 female, who were taking olanzapine for any condition for more than a month at a constant dose were enrolled in the study. Patients’ age, weight, body mass index (BMI, serum prolactin levels, and some biochemical values were recorded. Patients were taken from the review outpatient department (OPD after due consent. Results: Five each in male and female groups showed elevation of serum prolactin (estimated to be high if >20 ng/dl for males, and >25 ng/dl for females. In females, the elevation was found at lesser dose of olanzapine (13 mg/day, in males 18 mg/day and early in the treatment (2.4 months vs. 9.7 months in males. Males tended to show raised prolactin with higher doses of olanzapine (mean 18 mg/day. Females (26.31% also showed higher prevalence of prolactin elevation compared to males (13.51%. No other parameter was found to modify the prolactin levels. Conclusion: Olanzapine causes elevation of serum prolactin, though lesser degree than some other antipsychotics. Females are more prone to have raised serum prolactin with olanzapine compared to males. However, the elevation seems to be transient. Higher doses of olanzapine tend to cause elevation of serum prolactin. Serum prolactin estimation in patients taking olanzapine may be undertaken to maintain quality life, particularly in females.

  2. Effects of xylitol on blood glucose, glucose tolerance, serum insulin and lipid profile in a type 2 diabetes model of rats.

    Islam, Md Shahidul; Indrajit, Mitesh

    2012-01-01

    The present study was conducted to examine the antidiabetic effects of xylitol in a type 2 diabetes rat model. Six-week-old male Sprague-Dawley rats were randomly divided into 3 groups: normal control (NC), diabetic control (DBC) and xylitol (XYL). Diabetes was induced only in the DBC and XYL animal groups by feeding them a 10% fructose solution for 2 weeks followed by an injection (i.p.) of streptozotocin (40 mg/kg body weight). One week after the streptozotocin injection, the animals with a nonfasting blood glucose level of >300 mg/dl were considered to be diabetic. The XYL group was fed further with a 10% xylitol solution, whereas the NC and DBC groups were supplied with normal drinking water. After 5 weeks of intervention, food and fluid intake, body weight, blood glucose, serum fructosamine and most of the serum lipids were significantly decreased, and serum insulin concentration and glucose tolerance ability was significantly increased in the XYL group compared to the DBC group. Liver weight, liver glycogen and serum triglycerides were not influenced by feeding with xylitol. The data of this study suggest that xylitol can be used not only as a sugar substitute but also as a supplement to antidiabetic food and other food products. Copyright © 2012 S. Karger AG, Basel.

    Irisin has been proposed to regulate metabolic diseases such as obesity, diabetes or metabolic syndrome which are common comorbidities in psoriasis. The aim of this study was to evaluate the serum irisin level in psoriasis and elucidate possible associations with disease activity, inflammatory or metabolic parameters and topical treatment. Thirty-seven individuals with active plaque-type psoriasis and 15 healthy controls were enrolled. Blood samples were collected before and after two weeks of therapy. Serum irisin concentrations were examined by enzyme-linked immunosorbent assay (ELISA). The results were correlated with psoriasis area and severity index (PASI), body mass index (BMI), inflammatory and biochemical markers, lipid profile and effectiveness of topical treatment. Irisin serum levels were insignificantly increased in psoriatic patients in comparison to the controls (p = 0.38). No significant correlations between investigated adipokine and several indicators of metabolic disorders, nor BMI (p = 0.37) or PASI (p = 0.5) were found. Significant positive correlations with C-reactive protein (CRP) (0.009), lipocalin-2 (p = 0.02), age (p = 0.02) and disease duration (p = 0.008) were noted. After topical treatment, serum irisin level did not significantly change (p = 0.31), despite clinical improvement. Irisin might be a marker of inflammation in psoriatic patients, but may not be a reliable indicator of metabolic conditions, severity of psoriasis nor efficacy of antipsoriatic treatment.

    Myking, O.; Kjoesen, B.; Bassoee, H.H.

    1980-01-01

    The influence of pooled serum from either obese or normal weight males on glucose metabolism in human leucocytes has been studied. Leucocytes from normal weight males were incubated with 10-90% pooled serum and either [U- 14 C], or [1- 14 C]glucose. Compared to serum from the normal weight males, serum from the obese group had a more stimulating effect on the 14 CO 2 and [ 14 C]lactate production from [U- 14 C]glucose and on the 14 CO 2 production from [1- 14 C]glucose. The two serum pools had the same stimulating effect on the Embden-Meyerhof pathway as indicated by the formation of [ 14 C]lactate from [l- 14 C]glucose. Calculations revealed that the activity in the pentose phosphate pathway was stimulated more by serum from obese, than from normal weight males. It is a possibility that increased stimulation of the pentose phosphate pathway may contribute to the development of overweight. (author)

    Objective: To determine the serum 25-hydroxycalciferol levels [25(OH)D] in adults with pre-diabetes and normoglycaemia to examine a possible association of vitamin D deficiency with pre-diabetes. Study Design: Case control study. Place and Duration of Study: Armed Forces Institute of Pathology, Rawalpindi, from November 2012 to July 2013. Methodology: A total of 272 adults including 136 pre-diabetics and 136 normoglycaemics of either gender aged 20 years and above were consecutively inducted. Patients with diabetes mellitus, pregnancy, rickets and osteomalacia, ischemic heart disease, chronic kidney disease and chronic liver disease were excluded. Fasting Plasma Glucose (FPG) was estimated with hexokinase method on Modular p800 Roche chemistry analyzer while serum 25(OH)D was measured on Diasorin Liaison immunoassay analyzer using the chemiluminescent technique. Mean 25(OH)D levels in pre-diabetic and normoglycaemic groups were compared using Mann-Whitney U test. Spearman's correlation coefficient 'rs' was determined between serum 25(OH)D and FPG. Odds ratio for vitamin D deficiency was also calculated. Results: Mean serum 25(OH)D level was low in pre-diabetics (23.2 nmol/L) as compared to normoglycaemics (29 nmol/L; p=0.001). Serum 25(OH)D level had inverse correlation with FPG (rs = -0.448, p=0.000). There was also significant association of vitamin D deficiency with pre-diabetes compared with normoglycaemia (OR: 2.21, p= 0.016; 95 percentage CI: 1.15-4.27). Conclusion: Vitamin D deficiency with pre-diabetes suggested that vitamin D may have an important role in pathogenesis of pre-diabetes. (author)

  9. Effect of body mass index on serum leptin levels

    Paul, R.F.; Hassan, M.; Nazar, H.S.

    2012-01-01

    Background: Leptin is product of ob gene, an adipose tissue derived hormone that plays a key role in the regulation of body fat mass by regulating appetite and metabolism while balancing energy intake and energy expenditure. The objective of the study was to evaluate possible association between serum leptin levels and Body Mass Index (BMI) of gender in adult age group. Methods: Two-hundred-seventy subjects aged 20-50 years were randomly selected from general population of Abbottabad. The subjects were grouped on the basis on BMI (89 normal, 92 overweight, and 89 obese). After complete evaluation, demographic data was recorded and BMI. Non-fasting venous blood samples were drawn to measure serum leptin and serum glucose levels. The data were analysed using SPSS-15 calculating mean, percentage, independent t-test and chi-square test. Correlation and regression curve analysis were obtained, and p and r values were calculated. Results: Serum leptin levels and differences between genders were significant in all body mass indices. For normal BMI group the mean values for leptin were 2.6+-1.5 gamma g/ml in men, and 17.3+9-10.2 gamma g/ml for women. For Group-2 mean leptin levels in men were 9.9+-6.8 gamma g/ml and in women were 34.8+-13.6 gamma g/ml. For Group-3 BMI comprising obese subjects mean values for men were 21.3+-14.2 gamma g/ml and for women were 48.21+-21.2 gamma g/ml (p<0.001). Conclusion: A progressive increase in serum leptin concentration was observed with an increase in BMI. Significant difference between leptin concentrations in either gender was found in normal, overweight and obese subjects. (author)

    1983-01-01

    It is already well known that many factors are involved in maintaining normal blood glucose level. The amount and components of meal are also thought to be some of the factors which affect the blood glucose and insulin levels. It is reported that as for Koreans sugar takes up over 75% out of 2,098 kcal, the average daily calorie intake per adult. It implies that Koreans take a high-sugar diet compared with Westerners who take 40-50% of sugar out of their total average daily calorie. For the purpose of studying diurnal variations in serum glucose, insulin and C-peptide of normal Koreans adults based on ordinary Korean diet, we selected 13 normal Korean male adults and divided them into two groups, Group I (7 persons) and Group II (6 persons). We put Group I on 3,100 kcal and 75% sugar diet, and Group II on 2,100 kcal and 69% sugar diet per day for over 4 days. Serum glucose, insulin and C-peptide were checked every 30 minutes or every hour throughout 2 hour. Results are as follows: 1. As for serum glucose level, in the preprandial fasting state in the morning, mean±S.D. of Group I was 91.1±3.2 mg%, while that of Group II is 82.5±4.4 mg%. Both groups showed peaks of increased glucose level t postprandial 1 hour after each meal. The peak returned to the level shown during the fasting state at postprandial 1 hour after breakfast while the relatively high glucose levels were maintained respectively even for 2 or 3 hours after lunch and dinner. 2. As for serum insults level, Group I showed mean±S.D. of 14.7±3.0 μU/ml while Group II shows that of 7.0±2.6 μU/ml in the fasting state. Group I particularly showed the largest peak from preprandial a half or one and half an hour to postprandial one hour of lunch, and made relatively small peaks (47.7±10.8 μU/ml) at postprandial 1 hour after breakfast and dinner. No such large peak was marked in Group II, though it showed relatively similar patterns of peak after each meal. 3. As for C-peptide, in the fasting state

Group I particularly showed the largest peak from preprandial a half or one and half an hour to postprandial one hour of lunch, and made relatively small peaks (47.7+-10.8 muU/ml) at postprandial 1 hour after breakfast and dinner. No such large peak was marked in Group II, though it showed relatively similar patterns of peak after each meal. 3. As for C-peptide, in the fasting state

    Hyperhomocysteinemia has been considered an independent risk factor in the development of stroke. The present study was undertaken to evaluate serum homocysteine levels in patients with cerebrovascular accidents among the Manipuri population and to compare with the normal cases. Ninety-three cerebrovascular accident cases admitted in the hospital were enrolled for the study and twenty-seven age and sex matched individuals free from cerebrovascular diseases were taken as control group. Serum homocysteine levels were estimated by ELISA method using Axis homocysteine EIA kit manufactured by Ranbaxy Diagnostic Ltd. India. The finding suggests that hyperhomocysteinemia is associated with cerebrovascular accident with male preponderance, which increases with advancing age. However, whether hyperhomocysteinemia is the cause or the result of cerebrovascular accidents needs further investigations.

    OBJECTIVE Progranulin has recently been introduced as a novel adipokine inducing insulin resistance and obesity. In the current study, we investigated renal elimination, as well as association of the adipokine with markers of the metabolic syndrome. RESEARCH DESIGN AND METHODS Progranulin serum levels were quantified by enzyme-linked immunosorbent assay and correlated to anthropometric and biochemical parameters of renal function and glucose and lipid metabolism, as well as inflammation, in 532 patients with stages 1–5 of chronic kidney disease (CKD). RESULTS Median serum progranulin levels adjusted for age, sex, and BMI were significantly different between CKD stages with highest values detectable in stage 5 (stage 1, 58.3 µg/L; stage 2, 63.0 µg/L; stage 3, 65.4 µg/L; stage 4, 68.8 µg/L; and stage 5, 90.6 µg/L). Furthermore, CKD stage was the strongest independent predictor of circulating progranulin in our cohort. In addition, high-sensitivity interleukin-6 and adiponectin remained significantly and independently correlated with the adipokine. CONCLUSIONS We demonstrate that progranulin serum levels increase with deteriorating renal function. These findings are in accordance with the hypothesis that renal clearance is a major elimination route for circulating progranulin. Furthermore, the adipokine is positively and independently associated with markers of inflammation and adiponectin. PMID:23033238

    The aim of this study was to assess zinc levels in tinnitus patients, and to evaluate the effects of zinc deficiency on tinnitus and hearing loss. One-hundred patients, who presented to an outpatient clinic with tinnitus between June 2009 and 2014, were included in the study. Patients were divided into three groups according to age: Group I (patients between 18 and 30years of age); Group II (patients between 31 and 60years of age); and Group III (patients between 61 and 78years of age). Following a complete ear, nose and throat examination, serum zinc levels were measured and the severity of tinnitus was quantified using the Tinnitus Severity Index Questionnaire (TSIQ). Patients were subsequently asked to provide a subjective judgment regarding the loudness of their tinnitus. The hearing status of patients was evaluated by audiometry and high-frequency audiometry. An average hearing sensitivity was calculated as the mean value of hearing thresholds between 250 and 20,000Hz. Serum zinc levels between 70 and 120μg/dl were considered normal. The severity and loudness of tinnitus, and the hearing thresholds of the normal zinc level and zinc-deficient groups, were compared. Twelve of 100 (12%) patients exhibited low zinc levels. The mean age of the zinc-deficient group was 65.41±12.77years. Serum zinc levels were significantly lower in group III (p<0.01). The severity and loudness of tinnitus were greater in zinc-deficient patients (p=0.011 and p=0.015, respectively). Moreover, the mean thresholds of air conduction were significantly higher in zinc-deficient patients (p=0.000). We observed that zinc levels decrease as age increases. In addition, there was a significant correlation between zinc level and the severity and loudness of tinnitus. Zinc deficiency was also associated with impairments in hearing thresholds.

  15. Radioimmunoassay of serum digoxin levels. Clinical exploration

    Galland, F.; Geslin, P.; Kerjean, J.; Six, P.; Tadei, A.; Jallet, P.

    1982-01-01

    This work undertakes, in a second part, the clinical exploration of 947 serum digoxin levels of 281 hospitalized patients on a cardiology ward. Our results, which coincide with those of other researchers, have led us to draw certain practical conclusions: the posology is determined first of all according to kidney function, weight and age of the patient. When the treatment is insufficient or, on the other hand, poorly tolerated, a serum digoxin level is performed permitting thus: in the case of ineffective treatment: to be sure of the patient's cooperation, to increase the posology if the serum digoxin level is not in the toxic zone, to discover an eventual pharmacokinetic problem; to establish the responsability of digitalis (when there are signs of intolerance or of intoxication), in case of arrhythmia, in patients with pacemakers, when associated drugs are capable of causing similar adverse effects; to better manage a digitalis treatment in a high risk patient (unstable renal function, advanced myocardial disease, chronic obstructive disease) [fr

    Full Text Available This study evaluated the nutritional value of sesame and flaxseed oils and their effects on the lipid and glucose profile of rats fed diets containing different fat combinations. Fatty acid composition, refractive index, and iodine and saponification values were analyzed to characterize the oils. In the biological assay, Wistar rats were fed different diets, whose fat composition consisted of varying combinations of flaxseed oil, sesame oil, and animal fat. The primary constituents of the sesame oil were oleic (28.6%, linoleic (28.4%, and lauric acid (14.6%; for the flaxseed oil they were alpha-linolenic (39.90%, oleic (17.97% and linoleic acid (12.25%. The iodine and saponification values of the oils were within the reference range. Rats fed flaxseed oil-based diets had the lowest serum cholesterol values, whereas rats fed diets with flaxseed oil + sesame oil + animal fat had the highest glucose levels. HDL levels decreased significantly with flaxseed oil. Sesame and flaxseed oils are sources of polyunsaturated fatty acids (PUFA, and the flaxseed oil-based diet had a hypocholesterolemic effect, whereas sesame oil showed oxidative stability since it contains high levels of monounsaturated and saturated fatty acids.

  17. Effect of chromium chloride supplementation on glucose tolerance and serum lipids including high-density lipoprotein of adult men.

    Riales, R; Albrink, M J

    1981-12-01

    Chromium deficiency may cause insulin resistance, hyperinsulinemia, impaired glucose tolerance, and hyperlipidemia, recovered by chromium supplementation. The effect of chromium supplementation on serum lipids and glucose tolerance was tested in a double-blind 12-wk study of 23 healthy adult men aged 31 to 60 yr. Either 200 micrograms trivalent chromium in 5 ml water (Cr) or 5 ml plain water (W) was ingested daily 5 days each week. Half the subjects volunteered for glucose tolerance tests with insulin levels. At 12 wk high-density lipoprotein cholesterol increased in the Cr group from 35 to 39 mg/dl (p less than 0.05) but did not change in the water group (34 mg/dl). The largest increase in high-density lipoprotein cholesterol and decreases in insulin and glucose were found in those subjects having normal glucose levels together with elevated insulin levels at base-line. The data are thus consistent with the hypothesis that Cr supplementation raises high-density lipoprotein cholesterol and improves insulin sensitivity in those with evidence of insulin resistance but normal glucose tolerance.

    Creatine kinase (CK: adenosine-5-triphosphate-creatine phosphotransferase) is an important enzyme of muscle cells; the presence of a large amount of the enzyme in blood serum is a biomarker of muscular injuries, such as acute myocardial infarction. This work describes a bi-enzyme (glucose oxidase and hexokinase based) biosensor for rapid and convenient determination of CK activity by measuring the rate of ATP production by this enzyme. Simultaneously the biosensor determines glucose concentration in the sample. Platinum disk electrodes were used as amperometric transducers. Glucose oxidase and hexokinase were co-immobilized via cross-linking with BSA by glutaraldehyde and served as a biorecognition element of the biosensor. The biosensor work at different concentrations of CK substrates (ADP and creatine phosphate) was investigated; optimal concentration of ADP was 1mM, and creatine phosphate - 10 mM. The reproducibility of the biosensor responses to glucose, ATP and CK during a day was tested (relative standard deviation of 15 responses to glucose was 2%, to ATP - 6%, to CK - 7-18% depending on concentration of the CK). Total time of CK analysis was 10 min. The measurements of creatine kinase in blood serum samples were carried out (at 20-fold sample dilution). Twentyfold dilution of serum samples was chosen as optimal for CK determination. The biosensor could distinguish healthy and ill people and evaluate the level of CK increase. Thus, the biosensor can be used as a test-system for CK analysis in blood serum or serve as a component of multibiosensors for determination of important blood substances. Determination of activity of other kinases by the developed biosensor is also possible for research purposes. Copyright © 2015 Elsevier B.V. All rights reserved.

    2018-01-01

    In both humans and animals, chemosensory stimuli, including odors and tastes, induce a variety of physiologic and mental responses related to energy homeostasis, such as glucose kinetics. The present study examined the importance of olfactory function in glucose kinetics following ingestion behavior in a simplified experimental scenario. We applied a conventional glucose tolerance test to rats with and without olfactory function and analyzed subsequent blood glucose (BG) curves in detail. The loss of olfactory input due to experimental damage to the olfactory mucosa induced a marked decrease in the area under the BG curve. Exposure to grapefruit odor and its main component, limonene, both of which activate the sympathetic nerves, before glucose loading also greatly depressed the BG curve. Pre-loading exposure to lavender odor, a parasympathetic activator, stabilized the BG level. These results suggest that olfactory function is important for proper glucose kinetics after glucose intake and that certain fragrances could be utilized as tools for controlling BG levels.

    Gc-globulin scavenges actin released from necrotic hepatocytes to the extracellular space. In 77 patients with fulminant hepatic failure (FHF) (excluding patients treated with liver transplantation), admission levels of serum Gc-globulin and degree of complexing with monomeric actin (complex ratio...... in the same range as the KCH criteria. An advantage of Gc-globulin is that it gives an estimate of the outcome already on admission. Acute liver transplantation should be considered in FHF patients with Gc-globulin less than 100 mg/L....

    1981-01-01

    Experiments were carried out on male white rats divided into four groups. In group one the blood glucose level was determined immediately after immobilization. In the other three groups, two hours following immobilization, the blood glucose level was determined every 20 minutes for 3 hours 40 minutes by the glucose oxidase method. Preliminary immobilization for 2 hours removed the increase in the blood glucose caused by the stress reaction. By the 2nd hour of immobilization in the presence of continuing stress, the blood glucose level stabilized and varied within 42 + or - 5.5 and 47 + or - 8.1 mg %. Within 2 hours after the immobilization, the differences in the blood glucose level of the rats from the control groups were statistically insignificant.

  3. The association between estimated average glucose levels and fasting plasma glucose levels in a rural tertiary care centre

    Raja Reddy P

    2013-01-01

    Full Text Available The level of hemoglobin A1c (HbA1c, also known as glycated hemoglobin, determines how well a patient’s blood glucose level has been controlled over the previous 8-12 weeks. HbA1c levels help patients and doctors understand whether a particular diabetes treatment is working and whether adjustments need to be made to the treatment. Because the HbA1c level is a marker of blood glucose for the previous 60- 90 days, average blood glucose levels can be estimated using HbA1c levels. Aim in the present study was to investigate the relationship between estimated average glucose levels, as calculated by HbA1c levels, and fasting plasma glucose levels. Methods: Type 2 diabetes patients attending medicine outpatient department of RL Jalappa hospital, Kolar between March 2010 and July 2012 were taken. The estimated glucose levels (mg/dl were calculated using the following formula: 28.7 x HbA1c-46.7. Glucose levels were determined using the hexokinase method. HbA1c levels were determined using an HPLC method. Correlation and independent t- test was the test of significance for quantitative data. Results: A strong positive correlation between fasting plasma glucose level and estimated average blood glucose levels (r=0.54, p=0.0001 was observed. The difference was statistically significant. Conclusion: Reporting the estimated average glucose level together with the HbA1c level is believed to assist patients and doctors determine the effectiveness of blood glucose control measures.

  4. Lithium modulates the chronic stress-induced effect on blood glucose level of male rats

    Popović Nataša

    2010-01-01

    Full Text Available In the present study we examined gross changes in the mass of whole adrenal glands and that of the adrenal cortex, as well as the serum corticosterone and glucose level of mature male Wistar rats subjected to three different treatments: animals subjected to chronic restraint-stress, animals injected with lithium (Li and chronically stressed rats treated with Li. Under all three conditions we observed hypertrophy of whole adrenals, as well as the adrenal cortices. Chronic restraint stress, solely or in combination with Li treatment, significantly elevated the corticosterone level, but did not change the blood glucose level. Animals treated only with Li exhibited an elevated serum corticosterone level and blood glucose level. The aim of our study was to investigate the modulation of the chronic stress-induced effect on the blood glucose level by lithium, as a possible mechanism of avoiding the damage caused by chronic stress. Our results showed that lithium is an agent of choice which may help to reduce stress-elevated corticosterone and replenish exhausted glucose storages in an organism.

  5. Effect of cinnamon extract on blood glucose level and lipid profile in alloxan induced diabetic rats

    Mahmood, S.; Khurshid, R.

    2011-01-01

    Background: Cinnamon has been shown to potentiate the hypoglycaemic effect of insulin through up regulation of the glucose uptake in cultured adipocytes of rats. This study tried to find out the effect of Cinnamon alone or in combination with Insulin in diabetic albino rats. Methods: Thirty rats were divided into three groups, A and B. Group A were given cinnamon extract 200 mg/Kg body weight daily orally and group B rats were given cinnamon extract 400 mg/Kg body weight daily. After six weeks blood glucose and lipid profile levels were evaluated in all the groups. Results: Group of rats given 200 mg cinnamon extract showed significant decrease of blood glucose concentration but there was slight or no change in the level of lipid parameters including serum cholesterol, triglyceride and lipoproteins (HDL, LDL-chol). On the other hand group of rats given 400 mg extract of cinnamon showed a better but non significant change in level of lipid related parameter while blood glucose level was significantly decreased. Conclusion: The cinnamon at a dose of 400 mg showed same effects on blood glucose level but better effects on lipid profiles especially of serum cholesterol level of group of rats compared to 200 mg of cinnamon extract. Cinnamon may be recommended as hypoglycaemic herb but not as hypolipidaemic herb. (author)

    The aim of this study was to investigate the effects of ginger supplementation on serum glucose, advanced glycation end products, oxidative stress, and systemic and vascular inflammatory markers in patients on peritoneal dialysis (PD). In this randomized, double-blind, placebo-controlled trial, 36 patients on PD were randomly assigned to either the ginger or the placebo group. The patients in the ginger group received 1000 mg/d ginger for 10 wk, whereas the placebo group received corresponding placebos. At baseline and the end of week 10, serum concentrations of glucose, carboxymethyl lysine, pentosidine, malondialdehyde (MDA), high-sensitivity C-reactive protein (hs-CRP), soluble intercellular adhesion molecule type 1 (sICAM-1), soluble vascular cell adhesion molecule type 1 (sVCAM-1), and sE-selectin were measured after a 12- to 14-h fast. Serum fasting glucose decreased significantly up to 20% in the ginger group at the end of week 10 compared with baseline (P ginger reduces serum fasting glucose, which is a risk factor for hyperinsulinemia, dyslipidemia, peritoneal membrane fibrosis, and cardiovascular disease, in patients on PD.

    2005-06-01

    It is well established that total systemic adiponectin is reduced in type 2 diabetic subjects. To date most studies have been concerned with the singular full-length protein or proteolytically cleaved globular domain. It is, however, apparent that the native protein circulates in serum as a lower molecular weight hexamer and as larger multimeric structures of high molecular weight (HMW). In this study we address the clinical significance of each form of the protein with respect to glucose tolerance. Serum was obtained from 34 Indo-Asian male subjects (BMI 26.5+/-3.1; age 52.15+/-10.14 years) who had undertaken a 2-h oral glucose tolerance test. An aliquot of serum was fractionated using velocity sedimentation followed by reducing SDS-PAGE. Western blots were probed for adiponectin, and HMW adiponectin as a percentage of total adiponectin (percentage of higher molecular weight adiponectin [S(A)] index) was calculated from densitometry readings. Total adiponectin was measured using ELISA; leptin, insulin and IL-6 were determined using ELISA. Analysis of the cohort demonstrated that total adiponectin (r = 0.625, p = 0.0001), fasting insulin (r = -0.354, p = 0.040) and age (r = 0.567, p = 0.0001) correlated with S(A). S(A) showed a tighter, inverse correlation with 2-h glucose levels (r = -0.58, p = 0.0003) than total adiponectin (r = -0.38, p = 0.0001). This study demonstrates the importance of the S(A) index as a better determinant of glucose intolerance than measurements of total adiponectin. Our findings suggest that HMW adiponectin is the active form of the protein.

    Low brain tissue glucose levels after acute brain injury are associated with poor outcome. Whether enteral nutrition (EN) reliably increases cerebral glucose levels remains unclear. In this retrospective analysis of prospectively collected observational data, we investigate the effect of EN on brain metabolism in 17 poor-grade subarachnoid hemorrhage (SAH) patients undergoing cerebral microdialysis (CMD) monitoring. CMD-values were obtained hourly. A nutritional intervention was defined as the clinical routine administration of EN without supplemental parenteral nutrition. Sixty-three interventions were analyzed. The mean amount of EN per intervention was 472.4 ± 10.7 kcal. CMD-glucose levels significantly increased from 1.59 ± 0.13 mmol/l at baseline to a maximum of 2.03 ± 0.2 mmol/l after 5 h (p  40) and the microdialysis probe location. The increase in CMD-glucose was directly dependent on the magnitude of increase of serum glucose levels (p = 0.007). No change in CMD-lactate, CMD-pyruvate, CMD-LPR, or CMD-glutamate (p > 0.4) was observed. Routine EN also increased CMD-glucose even if baseline concentrations were critically low ( < 0.7 mmol/l, neuroglucopenia; p < 0.001). These results may have treatment implications regarding glucose management of poor-grade aneurysmal SAH patients.

    To investigate the correlation between glucose concentrations in serum, plasma, and whole blood measured by a point-of-care glucometer (POCG) and serum glucose concentration measured by a biochemical analyzer. Prospective clinical study. 96 blood samples from 80 dogs and 90 blood samples from 65 cats. Serum, plasma, and whole blood were obtained from each blood sample. The glucose concentrations in serum, plasma, and whole blood measured by a POCG were compared with the serum glucose concentration measured by a biochemical analyzer by use of the Lin concordance correlation coefficient (ρc) and Bland-Altman plots. For both canine and feline samples, glucose concentrations in serum and plasma measured by the POCG were more strongly correlated with the serum glucose concentration measured by the biochemical analyzer (ρc, 0.98 for both canine serum and plasma; ρc, 0.99 for both feline serum and plasma) than was that in whole blood (ρc, 0.62 for canine samples; ρc, 0.90 for feline samples). The mean difference between the glucose concentrations determined by the biochemical analyzer and the POCG in serum, plasma, and whole blood was 0.4, 0.3, and 31 mg/dL, respectively, for canine samples and 7, 6, and 32 mg/dL, respectively, for feline samples. Results indicated that use of a POCG to measure glucose concentrations in serum or plasma may increase the accuracy and reliability of diagnostic and treatment decisions associated with glucose homeostasis disorders in dogs and cats.

  12. High dose flaxseed oil supplementation may affect fasting blood serum glucose management in human type 2 diabetics.

    2008-01-01

    Type 2 diabetes is characterized partially by elevated fasting blood serum glucose and insulin concentrations and the percentage of hemoglobin as HbA1c. It was hypothesized that each of blood glucose and its co-factors insulin and HbA1c and would show a more favorable profile as the result of flaxseed oil supplementation. Patients were recruited at random from a population pool responding to a recruitment advertisement in the local newspaper and 2 area physicians. Completing the trial were 10 flaxseed oil males, 8 flaxseed oil females, 8 safflower (placebo) oil males and 6 safflower oil females. Patients visited on two pre-treatment occasions each three months apart (visits 1 and 2). At visit 2 subjects were randomly assigned in double blind fashion and in equal gender numbers to take flaxseed oil or safflower oil for three further months until visit 3. Oil consumption in both groups was approximately 10 g/d. ALA intake in the intervention group was approximately 5.5 g/d. Power was 0.80 to see a difference of 1 mmol of glucose /L using 12 subjects per group with a p < 0.05. Flaxseed oil had no impact on fasting blood serum glucose, insulin or HbA1c levels. It is concluded that high doses of flaxseed oil have no effect on glycemic control in type 2 diabetics.

    Stefansson, Hrafnkell; Sigvaldason, Kristinn; Kjartansson, Hilmar; Sigurjonsdottir, Helga Águsta

    2017-01-01

    Severe hypertriglyceridemia is a known, but uncommon complication of diabetic ketoacidosis. We discuss the case of a 23-year-old, previously healthy, woman who initially presented to the emergency department with abdominal pain. Grossly lipemic serum due to extremely high triglyceride (38.6 mmol/L) and cholesterol (23.2 mmol/L) levels were observed with a high blood glucose (23 mmol/L) and a low pH of 7.06 on a venous blood gas. She was treated successfully with fluids and insulin and had no sequale of pancreatitis or cerebral edema. Her triglycerides and cholesterol was normalized in three days and she was discharged home on insulin therapy after five days. Further history revealed a recent change in diet with no meat, fish or poultry consumption in the last 12 months and concomitantly an increase in carbohydrate intake which might have contributed to her extremely high serum lipid levels. This case demonstrates that clinicians should be mindful of the different presentations of diabetic ketoacidosis. Key words: diabetic ketoacidosis, hypertriglyceridemia, hyperlipidemia, vegan diet, carbohydrate diet. Correspondence: Hrafnkell Stefansson, hrafnkell.stefans@gmail.com.

    Chen, Ching-Chu; Li, Tsai-Chung; Li, Chia-Ing; Liu, Chiu-Shong; Wang, Hui-Ju; Lin, Cheng-Chieh

    2005-04-01

    Resistin is a novel adipocyte-secreted hormone that has been proposed to be the link between obesity and diabetes, although little appears to be known regarding the physiological role of resistin in human beings. We aimed to explore the relationship between serum resistin level and certain anthropometric and metabolic parameters. Seventy-one healthy subjects with a mean body mass index of 23 kg/m 2 or greater were recruited in this study. Anthropometric measurements including height, weight, body mass index, waist and hip circumferences, waist-to-hip ratio, and blood pressure were recorded. Insulin resistance was measured by homeostasis model assessment (HOMA). Fasting serum resistin, insulin and plasma glucose, lipid profiles, and uric acid levels were measured. The results revealed that serum resistin level did not correlate with any markers for adiposity, blood pressure, fasting plasma glucose, or uric acid level for either sex. Serum resistin level correlated negatively with fasting insulin level (gamma=-0.455, P=.006) and HOMA (gamma=-0.455, P=.006) in women but not in men. Serum resistin level only correlated negatively with high-density lipoprotein cholesterol (HDL-C) level in men (gamma=-0.347, P=.038); there was no correlation between serum resistin level and lipid profiles in women. Multiple linear regression analysis using the logarithm of resistin as a dependent variable revealed that only HDL-C level (beta=-.058, P=.019) was an independent significant predictor for resistin in men; however, the analysis revealed that HDL-C level (beta=-.044, P=.029) and HOMA (beta=-.719, P=.004) were independent significant predictors for resistin in women. In conclusion, resistin is not related to adiposity, blood pressure, insulin resistance, fasting plasma glucose level, and most lipid profiles. Resistin correlates negatively with HDL-C level for both sexes. The role of resistin in metabolic syndrome warrants further investigation.

    To investigate the association between chemerin level in the first trimester of pregnancy and the risk of gestational diabetes mellitus. The blood samples of 212 women at 8-12 weeks of gestation were collected. After screening for gestational diabetes mellitus (GDM), 19 women with GDM and 20 women randomly selected from 144 women with normal glucose tolerance (NGT) were included in the study. Blood samples were collected from these women. Triglycerides, glucose, total cholesterol, and HDL cholesterol, LDL cholesterol, insulin and chemerin were measured. Gestational weight gain and body mass index was assessed. Serum levels of chemerin were significantly elevated during late gestation, and the risk of GDM was positively associated with maternal serum chemerin in the first trimester. Serum chemerin level during the first trimester of pregnancy has the potential to predict risk of GDM.

    The normal fasting plasma glucose level was recently defined as less than 100 mg per deciliter (5.55 mmol per liter). Whether higher fasting plasma glucose levels within this range independently predict type 2 diabetes in young adults is unclear. We obtained blood measurements, data from physical examinations, and medical and lifestyle information from men in the Israel Defense Forces who were 26 to 45 years of age. A total of 208 incident cases of type 2 diabetes occurred during 74,309 person-years of follow-up (from 1992 through 2004) among 13,163 subjects who had baseline fasting plasma glucose levels of less than 100 mg per deciliter. A multivariate model, adjusted for age, family history of diabetes, body-mass index, physical-activity level, smoking status, and serum triglyceride levels, revealed a progressively increased risk of type 2 diabetes in men with fasting plasma glucose levels of 87 mg per deciliter (4.83 mmol per liter) or more, as compared with those whose levels were in the bottom quintile (less than 81 mg per deciliter [4.5 mmol per liter], P for trend <0.001). In multivariate models, men with serum triglyceride levels of 150 mg per deciliter (1.69 mmol per liter) or more, combined with fasting plasma glucose levels of 91 to 99 mg per deciliter (5.05 to 5.50 mmol per liter), had a hazard ratio of 8.23 (95 percent confidence interval, 3.6 to 19.0) for diabetes, as compared with men with a combined triglyceride level of less than 150 mg per deciliter and fasting glucose levels of less than 86 mg per deciliter (4.77 mmol per liter). The joint effect of a body-mass index (the weight in kilograms divided by the square of the height in meters) of 30 or more and a fasting plasma glucose level of 91 to 99 mg per deciliter resulted in a hazard ratio of 8.29 (95 percent confidence interval, 3.8 to 17.8), as compared with a body-mass index of less than 25 and a fasting plasma glucose level of less than 86 mg per deciliter. Higher fasting plasma glucose

    2014-06-01

    To determine the association of osteopenia with levels of serum 25-hydroxyvitamin D and HOMA-IR values in postmenopausal women. Methods One hundred healthy postmenopausal women were included in a cross-sectional study. Venous blood was collected after an overnight fast and 25-hydroxyvitamin D, glucose and insulin levels were measured. HOMA-IR was calculated. Bone mineral density was measured with a dual X-ray absorptiometer. There was no difference in serum 25-hydroxyvitamin D levels and HOMA-IR values between the two groups. A weak positive correlation between serum 25-hydroxyvitamin D levels and osteopenia was detected. Insulin resistance had a weak negative association with osteopenia. The correlations between osteopenia and serum 25-hydroxyvitamin D levels and HOMA-IR values were weak among early postmenopausal women.

    Recent evidence from animal studies indicates that fibroblast growth factor 21 (FGF21), an endocrine hormone that regulates glucose, lipid metabolism, and energy homeostasis, is regulated by T3. However, the role of FGF21 in hyperthyroid patients is unknown. The objective was to study serum FGF21 levels in hyperthyroid patients and the association of serum FGF21 levels with hyperthyroidism. This was a case-control study. A total of 119 hyperthyroid patients and 108 healthy subjects were recruited. Of them, 41 hyperthyroid patients received thionamide treatment for 3 months until euthyroidism was obtained. Serum FGF21 levels were determined using the ELISA method. Serum FGF21 levels were significantly elevated in hyperthyroid patients as compared with normal subjects [median 290.67 (interquartile range, 156.60-502.33) vs 228.10 (169.85.25-320.10) pg/mL; P treatment, serum FGF21 levels in hyperthyroid patients declined markedly from 249.10 (139.10-444.00) to 106.90 (38.70-196.15) pg/mL (P hyperthyroidism. With adjustment for potential confounders, serum FGF21 remained independently associated with hyperthyroidism, with an adjusted odds ratio of 3.123 (95% confidence interval, 1.306-7.468) (P = .010). Serum FGF21 levels were elevated in patients with hyperthyroidism and declined after thionamide treatment. And serum FGF21 level was independently associated with hyperthyroidism.

  19. An examination of the hexokinase method for serum glucose assay using external quality assessment data.

    Westwood, A; Bullock, D G; Whitehead, T P

    1986-01-01

    Hexokinase methods for serum glucose assay appeared to give slightly but consistently higher inter-laboratory coefficients of variation than all methods combined in the UK External Quality Assessment Scheme; their performance over a two-year period was therefore compared with that for three groups of glucose oxidase methods. This assessment showed no intrinsic inferiority in the hexokinase method. The greater variation may be due to the more heterogeneous group of instruments, particularly discrete analysers, on which the method is used. The Beckman Glucose Analyzer and Astra group (using a glucose oxidase method) showed the least inter-laboratory variability but also the lowest mean value. No comment is offered on the absolute accuracy of any of the methods.

    Ramadass, S; Basu, Sharbari; Srinivasan, A R

    2015-01-01

    Magnesium deficiency is commonly associated with endocrine and metabolic disorders, especially with Diabetes Mellitus type 2 though the mechanism of hypomagnesemia in Diabetes Mellitus is not completely known. There is a close association between metabolic control of Diabetes Mellitus and impaired magnesium balance. To estimate the serum levels of magnesium in patients of with Diabetes Mellitus type 2 and to find a correlation if any, with the duration and control (by estimating HbA1c) of Diabetes Mellitus type 2. Fifty patients of Diabetes Mellitus type 2 were included in the study. Blood samples were analyzed for fasting and post prandial glucose, HbA1c and magnesium. The patients were grouped into three categories based upon their HbA1c levels into those with good control, need intervention and poor control. The three groups were compared with reference to their mean levels of blood glucose and magnesium. Association of serum magnesium levels with HbA1c, Fasting and postprandial blood glucose and duration of Diabetes Mellitus was also done. Serum magnesium levels were found to decline with rise in HbA1c levels and with duration of Diabetes Mellitus type 2. Hypomagnesemia is linked to poor control of Diabetes Mellitus type 2 and depletion of serum magnesium occurs exponentially with duration of disease. Copyright © 2014 Diabetes India.

    Full Text Available Objectives: Adipose tissue, besides its main function as an energy storage depot, is currently considered an endocrine organ that secretes several self-produced cytokines. Leptin and resistin play an important role in energy homeostasis, glucose, lipid metabolism and regulation of body weight. The aim of the current study was to determine the concentration of leptin and resistin in pre-operational and post-operational periods of patients diagnosed as colorectal cancer.Materials and methods: The body mass index (BMI and values of leptin and resistin in blood at diagnosis were measured in 12 colorectal cancer patients in pre- and post-operational periods and in 12 age- and sex-matched controls. Serum leptin and resistin concentrations were measured by ELISA method.Results: Decreased leptin (1.95±0.62 ng/ml and resistin (4.32±1.83 ng/ml levels were found in pre-operational group compared with the control group (leptin: 6.12±0.82 ng/ml; resistin: 10.75±1.46 ng/ml (p0.05.Conclusion: We conclude that serum concentration of leptin and resistin may have a role in patients with colorectal cancers. Further studies are needed to investigate the possible prognostic value of leptin and resistin in clinical practice of patients with colorectal cancers.

    Full Text Available Diabetes Mellitus (DM is a chronic disease with high prevalence, associated with various debilitating complications and can decreases the quality of life in people with it. It is important for people with DM to doing exercise to control the stability of their blood glucose levels. The purpose of this study was to finding out the association between frequency, duration, and intensity of exercise with average blood glucose levels in people with DM. This was an observational study that used case control design. Data obtained from interview with 20 samples from case group and 20 samples from control group, that had been chosen with systematic random sampling technique. Dependent variable of this study was the average blood glucose levels and independents variables were frequency, duration, intensity, and the kind of exercise. This study used Chi Square test 3 × 2 contingency tables to finding out the association and risk of dependent variable with independent variables,. The results showed that exercise factors that associated to average blood glucose levels were duration of exercise (p = 0.022 and intensity of exercise (p = 0.021. The frequency of exercise does not associated to average blood glucose levels (p = 0.340. Diabetic patients who did not do any exercise have the risk of having uncontrolled blood glucose levels. The conclusion was duration and intensity of exercise related significantly to blood glucose levels. By doing exercise three times a week for 30 minutes or more can decreases the risk of uncontrolled blood glucose levels in people with DM.

    2007-01-01

    In order to find out the correlations between serum leptin levels and viral hepatitis, the serum leptin levels in 167 patients with viral chronic hepatitis, 87 patients with fatty liver, and 80 control subjects were determined by radioimmunoassay. The liver function (ALT, AST), glucose(Glu) and total cholesterol(TC) in these patients were also measured. Compared with controls and patients with fatty liver, the levels of serum leptin in patients with viral hepatitis were significantly increased (P 0.05). The increase of serum leptin levels in the patients with viral hepatitis was correlated positively with the severity of liver inflammation. Therefore, the leptin can be regarded as an indicator to reflect the severity of liver inflammation. (authors)

    1984-01-01

    The influence of the spleen homogenate injection as a curative substance against gamma irradiation effects has been investigated in male albino rats. The parameters tested were, life span, serum glucose level, liver glycogen content, serum protein fractions and A/G ratio. The results obtained are as follows: Irradiated group showed 100% mortality over 22 days, this percentage dropped to 60% over 30 days for irradiated group received spleen homogenate treatment. Irradiated animals, recorded initial hyperglycaemia which diminished by time, whereas the liver glycogen concentration showed first to initially increase then to decrease abruptly. Treatment with spleen homogenate after irradiation ameliorated the magnitude of radiation induced hyperglycaemia and liver glycogen depletion. The serum Albumin/Globulin ratio decreased by irradiation due to the decrease in the serum albumin accompanied by an increase in the serum globulin content. This ratio could be restored towards its normal level in irradiated animals received spleen homogenate treatment. The data obtained suggests the possibility of using spleen homogenate for the treatment of accidental radiation syndrome

    2006-01-01

    Full Text Available Secondary hyperparathyroidism (SHPT is a common, important, and treatable complication of end-stage renal disease. This study was conducted to investigate the role of serum magnesium (Mg in regulating the secretion of parathyroid hormone (PTH by the parathyroid gland in patients on maintenance hemodialysis (HD. Pre-dialysis serum levels of calcium (Ca, phosphorus (P, Mg, alkaline phosphatase (ALP, intact serum PTH (iPTH, serum 25-hydroxy Vitamin D (25-OH Vit D and plasma bicarbonate (HCO3 were measured. The Urea Reduction Rate as well as duration and dosage of HD treatment were noted. Our study did not show any significant correlation between serum Mg levels and duration of HD treatment, levels of serum ALP, and plasma HCO3, Ca and P. An inverse correlation, albeit insignificant, was found between the serum Mg levels and iPTH (r=-0.30 p=0.079; also, a significant positive correlation was found between serum Mg levels and serum 25-OH Vit D levels (r= 0.40 p= 0.009. Our findings are in agreement with previous data, which suggest that factors other than serum Mg are more important in the regulation of PTH secretion in HD patients. A positive and strong association between serum Mg with 25-OH Vit D needs to be studied in greater detail.

  11. Serum level of hormone and metabolites in pregnant rabbit does

    2010-01-01

    Full Text Available The aims of this study were to compare the hormones and metabolites serum levels and the reproductive performances of nulliparous (n=100 and primiparous pregnant does submitted to artificial insemination (AI 11 days post-partum. On the day of AI, all the does were weighed and the sexual receptivity was evaluated. The kits were weaned at 26 day. Blood samples were collect by punc- ture of the marginal ear vein from one day before AI until few days before the kindling and assayed for hormones and metabolites. The higher sexual receptivity and the fertility in nulliparous than in primiparous does confirmed the negative effect of lactation. Nulliparous does showed higher blood con- centration of leptine than primiparous, and in both the groups such level lowered during pregnancy, probably reflecting the reduction of the fat reserve. The insuline level increased during pregnancy in either groups as a consequence of the growing of the foetuses. In nulliparous does the cortisol, NEFA and T3 concentrations were higher than primiparous does. The glucose levels were similar in both the groups probably due to the homeostatic mechanisms controlling the glycemia. Hormonal and metabo- lite analyses represent a good tool for understanding the physiological mechanisms required to meet higher reproductive performance.

    2013-01-01

    Full Text Available The role of inflammation being minimal in the pathogenesis of type 2 diabetes mellitus (T2DM in nonobese patients; the aim of the study was to investigate the role of adenosine deaminase (ADA and see its association with diabetes mellitus. The preliminary case control study comprised of 56 cases and 45 healthy controls which were age and sex matched. 3 mL venous blood samples were obtained from the patients as well as controls after 8–10 hours of fasting. Serum ADA and routine biochemical parameters were analyzed. Serum ADA level was found significantly higher among nonobese T2DM subjects with respect to controls (38.77±14.29 versus 17.02±5.74 U/L; P<0.0001. Serum ADA level showed a significant positive correlation with fasting plasma glucose (r=0.657; P<0.0001 level among nonobese T2DM subjects, but no significant correlation was observed in controls (r=-0.203; P=0.180. However, no correlation was observed between serum ADA level compared to BMI and HbA1c levels. Our study shows higher serum ADA, triglycerides (TG and fasting plasma glucose (FPG levels in nonobese T2DM patients, and a strong correlation between ADA and FPG which suggests an association between ADA and nonobese T2DM subjects.

    2018-03-01

    Non-alcoholic fatty liver disease (NAFLD) is a form of clinical syndrome characterized by the fatty degeneration in liver histology and should be further investigated. The aim of the study was to investigate the effects of blood glucose, serum chemerin and insulin resistance on non-alcoholic fatty liver disease (NAFLD) in patients with type 2 diabetes mellitus to provide a basis for the prevention and treatment thereof. In total, 300 patients with type 2 diabetes mellitus treated and admitted into the Endocrinology Department of our hospital from June 2015 to June 2017 were enrolled and divided into the simple type 2 diabetes mellitus (group A) and concurrent NAFLD (group B) groups. The sex, age, body mass index (BMI), blood pressure, blood biochemical indexes and chemerin level were compared between the two groups. The patients in group B were further divided into the mild fatty liver (group B1), moderate fatty liver (group B2) and severe fatty liver (group B3) groups. The sex, age, BMI blood pressure, blood biochemical indexes and chemerin level were also compared among the three groups. Finally, the risk factors of type 2 diabetes mellitus complicated by NAFLD were analyzed via logistic regression. The BMI, fasting plasma glucose (FPG), 2 h post-prandial plasma glucose (2hPG), triglyceride (TG), total cholesterol (TC), low-density lipoprotein cholesterol (LDL-c), alanine aminotransferase (ALT), fasting insulin (FINS), homeostasis model assessment of insulin resistance (HOMA-IR) and HOMA-β indexes and serum chemerin level in group B were significantly higher than those in group A (Pdiabetes mellitus complicated by NAFLD is closely associated with severe glucose-lipid metabolism disorder and insulin resistance, and BMI, FPG, TC, LDL-c, FINS, HOMA-IR and chemerin constitute risk factors of concurrent NAFLD.

  16. The Effects of Capparis Spinosa Hydroalcoholic Extract on Blood Glucose and Lipids Serum in Diabetic and Normal Male Rats

    M Negahdarizadeh

    2011-06-01

    Full Text Available Introduction & Objective: Diabetes mellitus is one of the most common endocrine disorders in the world which affects glucose metabolism in the body. Diabetes mellitus is due to lack of insulin secretion and/or failure in insulin action. Researches conducted in the last few decades on plants have reported anti-diabetic properties for some herbs and their traditional use for diabetes treatment. Capparis spinosa is one of these herbs which are used as an anti-diabetic treatment in tribal medicine. The objective of the present study was to examine the anti-diabetic effects of Capparis spinosa on blood glucose and serum lipids in streptozotocin induced diabetes in male rats. Materials & Methods: In this experimental study conducted at Yasouj University of Medical Sciences in 2010, five groups of animals were selected. Three groups out of five were administered with intraperitoneal injection of streptozotocin to become diabetic. Group I were fed normal diet. Group II of animals received 20 mg/kg/day Capparis spinosa extract. Group III received no treatment (diabetic control and animals of groups IV and V were treated with capparis spinosa fruit extract 20 and 30 mg/kg body weight respectively for three weeks. Blood glucose, triglycerides, total cholesterol, LDL, HDL and body weight were measured in all animals. The collected data was analyzed by the SPSS software using one-way ANOVA. Results: Treatment with the 30 mg/kg/body weight of capparis spinosa fruit extract showed a significant decrease in blood glucose, triglycerides, total cholesterol and LDL, and a significant increase in HDL level. In addition, administration of 20 mg/kg/body weight of capparis spinosa extract decreased blood glucose and lipid levels in diabetic rats. Conclusion: It can be concluded that the oral administration of capparis spinosa extract at the dose of 30 mg/kg/body weight has glucose and lipids lowering activity in diabetic rats.

    2015-07-01

    The postprandial regulation of progranulin by oral uptake of lipids and carbohydrates in healthy individuals has not yet been investigated. The regulation of progranulin in 2 large cohorts of healthy volunteers during oral lipid tolerance test (OLTT; n=100) and oral glucose tolerance test (OGTT; n=100) was analyzed. One hundred healthy volunteers underwent OLTT and OGTT in an outpatient setting. Venous blood was drawn at 0 hours (h) (fasting) and at 2, 4, and 6 h in OLTT or 1 and 2 h in OGTT. A novel OLTT solution completely free of carbohydrates and protein was applied. Subjects were characterized by anthropometric and laboratory parameters. Serum concentrations of progranulin were measured by enzyme-linked immunosorbent assay (ELISA). Circulating progranulin levels remained unchanged during OLTT and OGTT. Fasting progranulin levels ranged between 31.3±8.7 and 40.6±7.7 ng/ml and were not different in subgroups addressing BMI, gender, family history, smoking habits, and hormonal contraception. There was a reciprocal correlation of progranulin with HDL (negative) and LDL cholesterol levels (positive). In healthy adults, fasting and postprandial circulating progranulin levels are not different in BMI subgroups. Oral uptake of carbohydrates and lipids does not influence circulating progranulin levels in a short-term manner. A postprandial and short-term regulation of this adipokine is absent, at least in healthy subjects. There is a negative correlation of progranulin with HDL cholesterol, but a positive correlation with LDL cholesterol. This reciprocal association might be of physiological importance for an individual's atherosclerotic risk. © Georg Thieme Verlag KG Stuttgart · New York.

    Full Text Available Serum enzyme levels were determined in goats of Marwari breed belonging to farmers’ stock of arid tract of Rajasthan state, India. The animals were grouped into healthy and stressed comprising of gastrointestinal parasiticised, pneumonia affected, and drought affected. The serum enzymes determined were sorbitol dehydrogenase, malate dehydrogenase, glucose-6-phosphate dehydrogenase, glutamate dehydrogenase, ornithine carbamoyl transferase, gamma-glutamayl transferase, 5’nucleotidase, glucose-6-phosphatase, arginase, and aldolase. In stressed group the mean values of all the enzymes increased significantly (p≤0.05 as compared to respective healthy mean value. All the enzymes showed highest values in the gastrointestinal parasiticised animals and least values in the animals having pneumonia. In gastrointestinal parasiticised animals maximum change was observed in G-6-Pase activity and minimum change was observed in malate dehydrogenase mean value. It was concluded that Increased activity of all the serum enzymes was due to modulation of liver functions directly or indirectly.

    The prevalence of obesity is increasing in dogs as well as in humans. C-reactive protein (CRP) is an important tool for the detection of inflammation and/or early tissue damage and is linked to obesity in humans. The objective of the present study was to determine if serum CRP levels are altered in obese dogs. Fifteen lean (control group) and 16 overweight (obese group) dogs were examined. Blood samples were collected under fasted conditions for serum determination of CRP, glucose, insulin, cholesterol, triglyceride, and fructosamine. Results indicated that obese dogs were insulin resistant because serum insulin and insulin/glucose ratios were higher than in lean dogs (P obese dogs than in controls (P obese group compared with the control group. Based on these results, it can be postulated that CRP production is inhibited by obesity and insulin resistance in dogs.

    Ghrelin is known as a regulator of the blood glucose homeostasis and food intake. In the present study, the possible roles of ghrelin located in the spinal cord in the regulation of the blood glucose level were investigated in ICR mice. We found that intrathecal (i.t.) injection with ghrelin (from 1 to 10 μg) caused an elevation of the blood glucose level. In addition, i.t. pretreatment with YIL781 (ghrelin receptor antagonist; from 0.1 to 5 μg) markedly attenuated ghrelin-induced hyperglycemic effect. The plasma insulin level was increased by ghrelin. The enhanced plasma insulin level by ghrelin was reduced by i.t. pretreatment with YIL781. However, i.t. pretreatment with glucagon-like peptide-1 (GLP-1; 5 μg) did not affect the ghrelin-induced hyperglycemia. Furthermore, i.t. administration with ghrelin also elevated the blood glucose level, but in an additive manner, in d-glucose-fed model. Our results suggest that the activation of ghrelin receptors located in the spinal cord plays important roles for the elevation of the blood glucose level. Copyright © 2014 Elsevier Inc.

  1. Emotionally arousing pictures increase blood glucose levels and enhance recall.

    Blake, T M; Varnhagen, C K; Parent, M B

    2001-05-01

    Arousal enhances memory in human participants and this enhancing effect is likely due to the release of peripheral epinephrine. As epinephrine does not readily enter the brain, one way that peripheral epinephrine may enhance memory is by increasing circulating blood glucose levels. The present study investigated the possibility that emotionally arousing color pictures would improve memory and elevate blood glucose levels in human participants. Blood glucose levels were measured before, 15 min, and 30 min after male university students viewed 60 emotionally arousing or relatively neutral pictures. Participants viewed each picture for 6 s and then had 10 s to rate the arousal (emotional intensity) and valence (pleasantness) of each picture. A free-recall memory test was given 30 min after the last picture was viewed. Although the emotionally arousing and neutral picture sets were given comparable valence ratings, participants who viewed the emotionally arousing pictures rated the pictures as being more arousing, recalled more pictures, and had higher blood glucose levels after viewing the pictures than did participants who viewed the neutral pictures. These findings indicate that emotionally arousing pictures increase blood glucose levels and enhance memory, and that this effect is not due to differences in the degree of pleasantness of the stimuli. These findings support the possibility that increases in circulating blood glucose levels in response to emotional arousal may be part of the biological mechanism that allows emotional arousal to enhance memory.

    Roomi, M.A.; Farooq, A.; Ullah, E.; Lone, K.P.

    2015-01-01

    The present study was planned to determine the serum vitamin D levels and its relation with the various components of metabolic syndrome (MetS) in MetS positive and MetS negative subjects. Methods: This analytical cross-sectional study on 88 subjects who were divided into two groups based on whether they fulfill the diagnostic criteria for MetS or not. Fasting serum glucose, lipid profile, insulin, HOMA-IR and vitamin D levels were measured. Two sample-t test and Mann-Whitney U tests were used to compare the differences. Pearson and Spearman correlation tests were used to observe the correlations. Results: BMI (p=0.001), waist/hip ratio (p=0.001), systolic blood pressure (p=0.010), diastolic blood pressure (p=0.010), fasting serum TGs (p = 0.001), TG/HDL ratio (p=0.001), fasting blood sugar (p=0.010), fasting serum insulin (p = 0.001) and HOMA-IR (p=0.001) were significantly high in MetS positive than MetS negative subjects. In MetS Positive subjects, serum vitamin D levels were found to have negative correlation with serum LDL (r= -0.485, p=0.001), total cholesterol (r= -0.408, p=0.007) and total cholesterol/HDL ratio (r= -0.355, p=0.019). Moreover, serum vitamin D levels were found to have positive correlation with HDL/LDL ratio (r= 0.443, p=0.003). Other components of MetS did not show significant correlation with serum vitamin D levels in MetS positive subjects. In MetS negative subjects, serum vitamin D levels did not show any significant correlation with any of the study parameters. Conclusions: Serum vitamin D levels were correlated with a number of MetS components which may be controlled by optimizing vitamin D levels. (author)

    Spexin is a newly identified neuropeptide that is involved in satiety control, glucose, and lipids metabolism. It has also been related to human diseases, such as obesity and type 2 diabetes. However, whether spexin changes with age or not is still unclear. The aim of this study is to investigate the relationship between circulating spexin levels and age and to study their interaction effects on body mass index (BMI), fasting glucose, and -lipids. This is a cross-sectional study, including 68 healthy adult women whose ages are in a wide range (minimum: 23; median: 38.5; maximum: 64). The serum spexin levels were measured by an enzyme-linked immunosorbent assay. Fasting glucose, total cholesterol, triglycerides (TG), alkaline phosphatase, alanine aminotransferase, aspartate aminotransferase, urea, and creatinine were measured by routine biochemical test. Shapiro-Wilk's test, Spearman and Pearson correlation analyses, χ 2 test, and two-way analysis of variance were used to interpret the data. Serum spexin levels are significantly correlated with age (Spearman r = -0.277, P = 0.022), BMI (Spearman r = -0.445, P glucose (Spearman r = -0.302, P = 0.014), and TG (Spearman r = -0.324, P = 0.008). Spexin levels independently predict the risk of high BMI and high fasting glucose. No interaction effects of spexin and age on BMI and fasting glucose were found. Circulating spexin levels decrease with age, suggesting a possible role of this peptide in aging-related functions and disorders. Further investigations are needed to expand the clinical significance of this finding.

  4. Effect of melatonin on serum glucose and body weights in streptozotocin induced diabetes in albino rats

    Hidayat, M.

    2015-01-01

    It has been demonstrated in experimental animal models that oxidative stress causes persistent and chronic hyperglycaemia, causing reduction in antioxidant defence system, ultimately leading to accumulation of free radicals.This study was performed to observe the effect of melatonin on serum glucose and body weights in streptozotocin induced diabetes in albino rats. Methods: Forty healthy adult male albino rats were included in the study and divided equally into 4 groups for 6 weeks. Group-A was taken as control. Group-B received streptozotocin I/P in a dose of 37 mg/kg body weight. Group-C received 10 mg/100 ml melatonin in drinking water and Group-D received only melatonin. Results: Streptozotocin significantly increased serum glucose and decreased weight in group B animals, whereas in group C, melatonin significantly restored serum glucose but could not restore the body weights reduced by streptozotocin. There was a significant reduction in body weight in melatonin treated group D animals. Conclusion: Melatonin decreases oxidative stress and hyperglycemia, but cannot restore the body weight reduced by streptozotocin. In fact, it further reduces body weight both in diabetic and normal state. (author)

    This study was designed to assess changes in glucose metabolism in rats administered single or repeated doses of MDMA. Two different experiments were performed: (1) A single-dose study with four groups receiving 20 mg/kg, 40 mg/kg, saline or heat, and (2) a repeated-dose study with two groups receiving three doses, at intervals of 2 h, of 5 mg/kg or saline. Rats were imaged using a dedicated small-animal PET scanner 1 h after single-dose administration or 7 days after repeated doses. Glucose metabolism was measured in 12 cerebral regions of interest. Rectal temperature and blood glucose were monitored. Peak body temperature was reached 1 h after MDMA administration. Blood glucose levels decreased significantly after MDMA administration. In the single-dose experiment, brain glucose metabolism showed hyperactivation in cerebellum and hypo-activation in the hippocampus, amygdala and auditory cortex. In the repeated-dose experiment, brain glucose metabolism did not show any significant change at day 7. These results are the first to indicate that MDMA has the potential to produce significant hypoglycaemia. In addition, they show that MDMA alters glucose metabolism in components of the motor, limbic and somatosensory systems acutely but not on a long-term basis. (orig.)

    2015-07-01

    Full Text Available Introduction & Objective: High levels of homocystein are a risk factor for insulin resistance, diabetes mellitus and cardio-vascular complications. This study was done to assess serum homocystein and folic acid levels and their relationship in women with gestational diabetes and compare them with normal pregnant women. Materials & Methods: This analytic epidemiologic case-control study was performed in Qazvin Kosar hospital in 2013-2015. 120 singleton pregnant women with 24-28 weeks of gestation according to 2-hour 75g oral glucose tolerance test were assigned to two groups; gestational diabetes (n=60, and normal pregnancy (n=60. Serum homocystein and folic acid levels were measured in two groups. Data were analyzed with statistical t-test and correlation method. Results: In gestational diabetes serum homocystein level was significantly higher (P<0.001 and folic acid was significantly lower (P<0.001 than normal pregnancy group .No relation-ship was observed between serum homocystein and serum folate. In both groups, serum folic acid was significantly related to fasting blood sugar. This relationship was inverse in gesta-tional diabetes group (P<0.001, r = - 0.512 and direct in normal pregnancy group (P=0.001 r =0.417. Conclusion: It seems folic acid has a role in regulation of serum homocystein level and blood sugar.(Sci J Hamadan Univ Med Sci 2015; 22 (2: 93-98

  10. Serum endocan levels in children with febrile neutropenia

    Full Text Available Endocan is an endotelial cell specific molecule; previous studies have shown that serum endocan levels increased in cancer and sepsis and are also related to the severity of sepsis. There are no clinical study about serum endocan levels in children with febrile neutropenia. The aim of this study was to evaluate serum endocan levels in pediatric leukemia patients with febrile neutropenia (n=33 and compare them with children with leukemia without fever (n=33 and also with healthy children (n=24. The median serum endocan level in the first group (children with febrile neutropenia was statistically significantly higher compared to the leukemic children without febrile neutropenia and also control group (P<0.01 for both. No difference was determined between the serum endocan levels of the leukaemia patients without febrile neutropenia and the healthy control group (P>0.05. Serum endocan levels were also similar with febrile neutropenia due to bacterial causes comparing with the idiopathic febril neutropenia. The results of this study showed increased serum endocan in children with leukemia during the febrile neutropenia episode, and no changes of serum endocan levels in children without leukemia without infection/fever. The monitoring of a series of serum endocan levels would be helpful for the course of febrile neutropenia.

    Concurrence of high glucose or diabetes in patients with dyslipidemia is presenting major challenges for clinicians. Although sporadically reported, a rational basis for the use of fibrates for the treatment of dyslipidemia with concurrent metabolic syndrome has not been established. In this study, wild-type (WT) and Ppara-null (KO) mice were fed a serial gemfibrozil- and fenofibrate-containing diet under the same experimental conditions for 14 days. Glucose level in the blood, glycogen storage in the liver tissues, and the potential toxic responses were assayed. Genes involved in glucose metabolism were determined by quantitative polymerase chain reaction analysis. Both the blood glucose level and the glycogen content in the liver were down-regulated by gemfibrozil but not by fenofibrate in WT mice, in a dose-dependent manner. This decrement did not occur in KO mice for either fibrate agent. Secondary regulation on the transcription of pyruvate kinase, and gluconolactonase were observed following gemfibrozil treatment, which was differential between WT mice and KO mice. Gemfibrozil, not fenofibrate, down-regulates systemic glucose level and glycogen storage in the liver dependent on PPARα, suggesting its potential value for treatment of dyslipidemia with concurrent diabetes or high glucose levels.

    Prediabetes is associated with an increased risk of cardiovascular disease (CVD). While the association of impaired glucose tolerance with CVD has been shown in many studies, the relationship between impaired fasting glucose (IFG) and CVD remains unclear. The purpose of this study was to compare the coronary artery calcium (CAC) scores of participants with normal fasting glucose versus those with IFG, according to fasting plasma glucose (FPG) levels, and to assess whether differences in CAC scores were independent of important confounders. Retrospective study. Health Promotion Center of the University Hospital (Gyeonggi-do, South Korea), during the period 2010-2014. Participants were enrolled from the general population who visited for a medical check-up. CAC was assessed in asymptomatic individuals by multidetector computed tomography. Anthropometric parameters and metabolic profiles were also recorded. Subjects were divided into four fasting glucose groups. Participants with a history of CVD or diabetes mellitus were excluded. Correlation between FPG and CAC scores, CAC score categories, and association between CAC score and FPG categories. Of 1112 participants, 346 (34.2%) had a CAC score > 0. FPG values in the IFG patients were positively but weakly correlated with CAC scores (r=0.099, P=.001). The incidence of CAC differed according to FPG level (P =110 mg/dL had a significantly higher risk of CAC than did subjects with normal fasting glucose (110.

    To comprehensively and exhaustively assess the relationship between serum ferritin levels and incidence of prediabetes in a prospective study. This prospective cohort study (n=7380) with a mean follow-up of 3.07 years (range: 1-7, 95% CI: 3.03-3.12) was conducted in Tianjin, China. Blood fasting glucose, oral glucose tolerance test, serum ferritin levels and other potentially confounding factors were measured at baseline and at each year of follow-up. Adjusted Cox proportional hazards regression models were used to assess the gender-specific relationship between baseline and mean serum ferritin quintiles and prediabetes. The incidence of prediabetes was 85 per 1000 person-years among men and 44 per 1000 person-years among women during follow-up (from 2007 to 2014). After adjusting for potential confounders, hazard ratios (95% CI) for prediabetes across baseline ferritin quintiles were: for men, 1.00, 1.13 (0.90-1.40), 1.20 (0.97-1.48), 1.41 (1.14-1.73) and 1.73 (1.41-2.11); and for women, 1.00, 1.01 (0.74-1.38), 0.68 (0.48-0.96), 0.84 (0.61-1.15) and 1.07 (0.80-1.45), respectively. Similar results were also observed for mean ferritin levels. Both baseline and mean serum ferritin levels were significantly and linearly related to prediabetes in men, whereas U-shaped relationships were observed between baseline and mean serum ferritin and prediabetes in women. The relationship between prediabetes risk and mean serum ferritin levels may be more stable than one with baseline serum ferritin levels. Copyright © 2016. Published by Elsevier Masson SAS.

  16. The effect of serum magnesium levels and serum endothelin-1 levels on bone mineral density in protein energy malnutrition.

    Ozturk, C F; Karakelleoglu, C; Orbak, Z; Yildiz, L

    2012-06-01

    An inadequate and imbalanced intake of protein and energy results in protein-energy malnutrition (PEM). It is known that bone mineral density and serum magnesium levels are low in malnourished children. However, the roles of serum magnesium and endothelin-1 (ET-1) levels in the pathophysiology of bone mineralization are obscure. Thus, the relationships between serum magnesium and ET-1 levels and the changes in bone mineral density were investigated in this study. There was a total of 32 subjects, 25 of them had PEM and seven were controls. While mean serum ET-1 levels of the children with kwashiorkor and marasmus showed no statistically significant difference, mean serum ET-1 levels of both groups were significantly higher than that of the control group. Serum magnesium levels were lower than normal value in 9 (36%) of 25 malnourished children. Malnourished children included in this study were divided into two subgroups according to their serum magnesium levels. While mean serum ET-1 levels in the group with low magnesium levels were significantly higher than that of the group with normal magnesium levels (p malnutrition. Our study suggested that lower magnesium levels and higher ET-1 levels might be important factors in changes of bone mineral density in malnutrition. We recommend that the malnourished patients, especially with hypomagnesaemia, should be treated with magnesium early.

  17. Association of Serum Ferritin Levels with Metabolic Syndrome and Insulin Resistance.

    The impact of CVDs and Type II DM is increasing over the last decade. It has been estimated that by 2025 their incidence will double. Ferritin is one of the key proteins regulating iron homeostasis and is a widely available clinical biomarker of iron status. Some studies suggest that prevalence of atherosclerosis and insulin resistance increases significantly with increasing serum ferritin. Metabolic syndrome is known to be associated with increased risk of atherosclerosis as well as insulin resistance. The present study was designed to explore the association of serum ferritin levels with metabolic syndrome and insulin resistance. The present study was prospective, cross sectional. The study protocol was approved by IEC. The study group consisted of 90 participants (50 cases of metabolic syndrome and 40 age and sex matched controls). Diagnosis of metabolic syndrome was done as per NCEP ATP III criteria. Estimation of serum Ferritin and Insulin was done by Chemiluminescence Immunoassay (CLIA) while Glucose by Glucose Oxidase and Peroxidase (GOD-POD) method. Insulin Resistance was calculated by HOMA IR score. Data obtained was statistically analysed by using student t-test. We found statistically significant rise in the levels of serum ferritin (p=syndrome as compared with controls. High serum ferritin levels though within normal range are significantly associated with both metabolic syndrome and insulin resistance.

    Objective: To compare serum leptin levels of diabetic and non-diabetic female subjects and also assess the relationship of hyperglycemia with serum insulin, C-peptide and leptin levels. Results: Serum leptin levels of obese diabetic and non-diabetic subjects were significantly higher as compared with lean diabetic patients and non-diabetic subjects (P<0.05). Leptin levels were positively correlated with serum insulin and C-peptide levels. Serum leptin increased with increase in body mass index and waist hip ratio was strongly related with insulin resistance in NIDDM. Conclusion: Leptin levels are increased in obesity and may play a role in development of insulin resistance and NIDDM. (author)

  20. Serum progranulin levels in relation to insulin resistance in childhood obesity.

    Alissa, Eman M; Sutaih, Rima H; Kamfar, Hayat Z; Alagha, Abdulmoeen E; Marzouki, Zuhair M

    2017-11-27

    Progranulin is an adipokine that is involved in the inflammatory response, glucose metabolism, insulin resistance, and may therefore be involved in chronic subclinical inflammation associated with the pathogenesis of childhood obesity. We aimed to investigate the association of circulating progranulin levels with metabolic parameters in children and to assess the importance of progranulin as a biomarker for metabolic diseases. A total of 150 children were consecutively recruited from the Pediatric Nutrition Clinics at King Abdulaziz University Hospital in Jeddah, Saudi Arabia. Children were classified into four groups based on quartile for serum progranulin. Anthropometric variables were measured in all study subjects. Fasting blood samples were collected for measurement of blood glucose, insulin and lipid profile. Children within the upper quartile for serum progranulin concentration were heavier, more insulin resistant and had higher concentrations of serum total cholesterol, triglycerides, insulin and high sensitivity C reactive protein compared to those in the lower quartile. On correlation analysis, serum progranulin concentrations were significantly related to general and central adiposity, metabolic parameters, markers of inflammation and insulin resistance. Stepwise multiple regression showed that 26.6% of the variability in serum progranulin could be explained by measures of adiposity. The increased serum progranulin concentrations were closely related to measures of adiposity, metabolic parameters, inflammatory marker and insulin resistance indices, suggesting that progranulin may be an excellent biomarker for obesity in childhood.

    2013-01-01

    The fact that bone mass density (BMD) is not useful for assessing fracture risk in diabetic patients (DM) seems problematic, because those populations are increasing in every country. Osteocalcin (OC) is synthesized by osteoblasts and is considered to be a marker of bone formation. The present study was carried out to evaluate the usefulness of OC as noninvasive biomarker of bone formation in diabetes mellitus type 2 (uncomplicated) and diabetic nephropathy. Immunoradiometric assay(IRMA) was used for the quantitative measurement of human intact OC both N-terminal and C-terminal fragments in the serum of the control and the studied groups. OC levels in the uncomplicated diabetic group were significantly lower while in the diabetic nephropathy group was significantly higher compared to control values . There was a weak negative correlation between OC and both fasting blood glucose and glycated Hb% in the diabetic group. In diabetic nephropathy patients, a weak positive correlation was observed between OC and protein creatinine ratio. The results concluded that changes in bone remodelling marker OC are present in both DM type 2 and diabetic nephropathy explaining osteopenia and osteoporosis observed in both cases.Therefore, an effective glycaemic control should be the hallmark of prevention and treatment of diabetes mellitus induced osteoporosis

    The authors present a radioimmunological method for determination of insulin (IRI) level in the human serum using magnesium silicate (talc) as adsorbent. The method is based on the phenomenon of selective adsorption of the free radioactive hormone. The optimal parameters for the method were determined. The serum level of IRI in clinically healthy subjects after oral glucose loading was established. The obtained results were compared with the results obtained by the radioimmunological method of double antibodies in stochastically grouped samples.

    Graphical abstract: In this paper, we reported a novel dual enzymatic-biosensor for simultaneous determination of glucose and cholesterol in serum and peritoneal macrophages (PMs) of diabetic mice to evaluate the diabetes-accelerated atherosclerosis risk. The biosensor was firstly modified with a poly-thionine (PTH) film as electron transfer mediator (ETM), then the gold nanoparticles (GNPs) were covered on the surface of PTH to act as tiny conduction centers for facilitating the electron transfer between enzymes and electrode. The schematic of the dual biosensor is shown in figure. The developed dual biosensor had good electrocatalytic activity toward the oxidations of glucose and cholesterol, exhibited a linear range from 0.008 mM to 6.0 mM for glucose with a detection limit of 2.0 {mu}M, and a linear range from 0.002 mM to 1.0 mM for cholesterol with a detection limit of 0.6 {mu}M. The results of the diabetic mice demonstrated that the cholesterol level was not changed obviously with the increase of glucose level in serum, while the cholesterol level was enhanced together with the increase of the glucose level in PMs. Previous studies have shown that the large accumulation of cholesterol in macrophage could lead to macrophage foam cell formation, the hallmark of early atherosclerosis. These findings indicated the possibility that high glucose induced by diabetes might increase the macrophage cholesterol level to further accelerate atherosclerosis development.

    Serum hyaluronan levels are increased in dialysis patients. We evaluated several factors that influence serum hyaluronan levels in 184 patients on chronic hemodialysis (duration 2.3 +/- 2.3 [SD] years). The levels were higher than normal in the whole group and in a subgroup of 133 patients without chronic infection, liver disease, or rheumatoid arthritis (215 +/- 19 and 205 +/- 22 microg/L, respectively). There was a tendency for the levels to be higher in a subgroup of patients with hepatitis c virus (HCV) infection. There was no correlation between hyaluronan levels, alanine aminotransferase (ALT), and duration or dose of dialysis. A weak but highly significant negative correlation between serum albumin levels and serum hyaluronan and ferritin levels was seen. The data suggest that chronic inflammation may explain, at least in part, the increased hyaluronan levels found in chronic dialysis patients.

    A nested, matched case-control study was conducted to assess the relationship between serum levels of copper and the subsequent risk of cancer. One hundred thirty-three cases of cancer were identified during 1974-1984 among 5000 members of a northwest Washington State employee cohort from whom serum specimens had been previously obtained and stored. Two hundred forty-one controls were selected at random from the cohort and were matched to the cases on the basis of age, sex, race, and date of blood draw. Serum copper levels were measured by atomic absorption spectrometry. Risk of a subsequent diagnosis of cancer was positively associated with serum copper levels, but only among those cases diagnosed within 4 years of the time the serum specimens were collected. Among cases diagnosed more than 4 years after specimen collection, there was no consistent association between serum copper levels and risk. Adjustment for age, sex, race, occupational status, cigarette smoking, family history of cancer, alcohol consumption, and, among females, use of exogenous hormones had no appreciable effect on these relationships. The findings suggest that the presence of cancer may increase serum copper levels several years prior to its diagnosis. They are less supportive of the hypothesis that serum copper levels affect cancer risk.

  14. Sodium serum levels in hypoalbuminemic adults at general medical wards

    Cunha Daniel Ferreira da

    1999-01-01

    Full Text Available Hypoalbuminemia may cause interstitial edema and hemodilution, which we hypothesized may influence serum sodium levels. Our purpose was to compare serum sodium levels of hospitalized adults with or without hypoalbuminemia. All sodium and albumin serum levels of 142 adults hospitalized at general medical wards over a six-month period were searched at a University Hospital mainframe computer. Relevant laboratory data and clinical details were also registered. Hypoalbuminemia was defined by serum albumin concentration < 3.3 g/dl Fisher, Mann-Whitney, and Student's t tests were applied to compare groups with or without hypoalbuminemia. Ninety-nine patients, classified as hypoalbuminemic, had lower blood hemoglobin (10.68 ± 2.62 vs. 13.54 ± 2.41, and sodium (135.1 ± 6.44 vs. 139.9 ± 4.76mEq/l and albumin (2.74 ± 0.35 vs. 3.58 ± 0.28g/dl serum levels than non-hypoalbuminemic (n=43. Pearson's coefficient showed a significant direct correlation between albumin and sodium serum levels (r=0.40 and between serum albumin and blood hemoglobin concentration (r=0.46. Our results suggest that hypoalbuminemic adults have lower serum sodium levels than those without hypoalbuminemia, a phenomenon that may be at least partially attributed to body water retention associated with acute phase response syndrome.

    Adipokines have been implicated in obesity, insulin resistance and sleep regulation. However, the role of chemerin and progranulin, two recently described adipokines, in the context of sleep remains unclear. The aim of this study was to compare nocturnal serum chemerin and progranulin levels between overweight/obese and normal-weight adolescents and to assess variations by sex, across different sleep stages and in relation to glucose metabolism. The study sample included 34 overweight/obese and 32 normal-weight adolescents from secondary schools and the Leipzig Research Center for Civilization Diseases (LIFE) Child study cohort. We obtained longitudinal serum adipokine levels during in-laboratory polysomnography followed by an oral glucose tolerance test. Overweight/obese adolescents had significantly higher mean nocturnal serum chemerin area under the curve (AUC) levels (348.2±133.3 vs. 241.7±67.7 vs. ng/mL×h, pprogranulin AUC was found between the groups. However, when assessing sex-specific levels, serum progranulin AUC levels were ~30% higher in overweight/obese males compared to overweight/obese females. Of note, nocturnal serum chemerin and progranulin AUC did not exhibit a correlation with markers of glucose metabolism or sleep stages. Collectively, we report a sexual dimorphism in nocturnal progranulin and chemerin levels, which may help explain underlying differences in energy balance and body composition between males and females in the context of obesity.

    2017-09-01

    Glycaemic control is recognized as one of the important aspects in managing critically ill patients. Both hyperglycaemia and hypoglycaemia independently increase the risk of patient mortality. Hence, the identification of optimal glycaemic control is of paramount importance in the management of critically ill patients. The aim of this literature review is to examine the current status of glycaemic control in critically ill adult patients. This literature review will focus on randomized controlled trials comparing intensive insulin therapy to conventional insulin therapy, with an objective to identify optimal blood glucose level targets for critically ill adult patients. A literature review was conducted to identify large randomized controlled trials for the optimal targeted blood glucose level for critically ill adult patients published since 2000. A total of eight studies fulfilled the selection criteria of this review. With current human and technology resources, the results of the studies support commencing glycaemic control once the blood glucose level of critically ill patients reaches 10 mmol/L and maintaining this level between 8 mmol/L and 10 mmol/L. This literature review provides a recommendation for targeting the optimal blood glucose level for critically ill patients within moderate blood glucose level target range (8-10 mmol/L). The need for uniformed glucometrics for unbiased reporting and further research for optimal blood glucose target is required, especially in light of new technological advancements in closed-loop insulin delivery and monitoring devices. This literature review has revealed a need to call for consensus in the measurement and reporting of glycaemic control using standardized glucometrics. © 2017 British Association of Critical Care Nurses.

    1985-01-01

    Measurements of the serum Vitamin B 12 concentrations of 49 black and 49 white healthy adults demonstrate a significantly higher mean serum Vitamin B 12 level in blacks when compared to whites. The reason for this difference appears to be genetic, although environmental factors may also be involved. It is suggested that clinical laboratories should establish their own separate reference values of serum Vitamin B 12 for blacks and whites in order to prevent misinterpretation of test results

    Full Text Available Osteoprotegerin (OPG wird in der entzündeten Synovialis bei chronischer Polyarthritis von Makrophagen, dendritischen Zellen und B-Zellen produziert. OPG hemmt die Differenzierung von Osteoklasten und ihre Aktivierung durch die Bindung an RANKL (receptor activator of NFkappaBbeta ligand. OPG könnte daher eine wichtige Rolle in der Verhinderung des Auftretens von Erosionen bei chronischer Polyarthritis spielen. In der vorliegenden Studie wurde untersucht, ob die Serumspiegel von Osteoprotegerin mit Entzündungsparametern oder der Gelenksdestruktion bei chronischer Polyarthritiskorrelieren. Patienten und Methoden: In 85 Sera von 68 Patienten mit chronischer Polyarthritis wurden die Serumspiegel von OPG untersucht und mit klinischen Parametern, Laborbefunden und dem Larsen-Score verglichen. Zur OPG-Bestimmung wurde ein Sandwich-ELISA (enzyme-linked-im-munosorbent-assay mit zwei spezifischen OPG-Antikörpern verwendet. Mit dem bindenden Antikörper wurde eine Mikrotiterplatte beladen, der zweite Biotin-konjugierte Antikörper wurde durch Streptavidin-Peroxidase und TMB gemessen. Der Immunoassay mißt sowohl freies als auch an RANKL gebundenes OPG. Zur statistischen Auswertung wurde ein SAS-Programm verwendet, als Tests wurden der Mann-Whitney-Test, die Spearman-Korrelation und die Varianzanalyse (ANOVA angewandt. Ergebnisse: Verglichen mit einer gesunden Kontrollgruppe (Alter 56-76 Jahre lagen die Mittelwerte von Serum-OPG bei chronischer Polyarthritis höher. Wenn man den Mittelwert der Gesunden für die Einteilung in höhere oder niedrigere Serum-OPG-Werte bei Patienten mit chronischer Polyarthritis verwendet, zeigt sich im Mann-Whitney-Test eine signifikante Korrelation nicht nur mit BSG und Rheumafaktor, sondern auch mit dem Larsen-Score. Die OPG-Spiegel korrelierten mit dem Rheumafaktor, der BSG und dem Serum-CRP (C-reaktives Protein signifikant positiv, der Larsen-Score zeigte nur einen statistischen Trend.

    Full Text Available Febrile convulsions (FC are the most common neurologic disorder in children 6-60 months of age. Zinc (Zn and copper (Cu play role as cofactors in more than 300 enzymatic activities significantly. The aim of this study was to evaluate the relationship serum levels of Zn and Cu with seizure occurrence in febrile children. In this case-control study, 270 children with 6 month to 6 years were evaluated. The patients were enrolled in three groups: a children with febrile convulsion, b febrile children without convulsion and c healthy ones. After recording of all patients’ characteristics, 5 mL blood was taken from peripheral vessels at the first 12 hours of hospitalization. Absorption of all samples was read by BRAIC (Rayleigh instrument company, WFX-130 model with calibration diagram, considering samples dilution levels. The mean of serum Zn levels in children with FC were significantly lower than other two groups. Mean serum Cu levels in children with FC and non-FC patients were significantly higher than healthy children. No meaningful differences were observed in serum levels of Zn and Cu among the girl or boy cases. This study showed significant lower serum zinc level in children with febrile seizure and meaningful higher serum copper level than control group cases. There was no significant difference in level of serum zinc and copper in term of sex.

  20. Evaluation of the serum zinc level in patients with vitiligo

    2017-04-01

    Full Text Available Introduction : Vitiligo is an acquired, idiopathic disorder characterized by circumscribed depigmented macules and patches, which affects approximately 0.1–2% of the general population worldwide. Zinc is an essential trace element that is necessary for growth and development at all stages of life. Some studies have reported an association between serum zinc levels and vitiligo. Aim : To measure the serum zinc level in patients with vitiligo compared to healthy subjects. Material and methods : One hundred patients with vitiligo and 100 healthy controls were referred to our clinic. The two groups were matched for age and sex. Atomic absorption spectrophotometry was used to measure serum zinc levels. The statistical analysis was performed using SPSS software. Results : The mean serum level of zinc in vitiligo patients and controls was 80.11 ±17.10 µg/dl and 96.10 ±16.16 µg/dl, respectively. The serum zinc level in patients with vitiligo was significantly lower than in healthy controls (p = 0.0001. Conclusions : The results of our study revealed a significant association between vitiligo and serum zinc levels. A relative decrease in the serum zinc level in vitiligo patients can highlight the role of zinc in the pathogenesis of vitiligo, and large-scale studies need to be conducted to confirm these findings and assess the effect of oral zinc supplements in patients with low zinc levels.

    High fluctuations in blood glucose are associated with various complications. The correlation between glycated hemoglobin (HbA1c) level and fluctuations in blood glucose level has not been studied in Japanese patients with type 2 diabetes. In the present study, blood glucose profile stratified by HbA1c level was evaluated by continuous glucose monitoring (CGM) in Japanese type 2 diabetes patients. Our retrospective study included 294 patients with type 2 diabetes who were divided by HbA1c level into five groups (≥6.0 to level and CGM data was analyzed. The primary end-point was the difference in blood glucose fluctuations among the HbA1c groups. The mean blood glucose level increased significantly with increasing HbA1c (P trend  levels of maximum blood glucose, minimum blood glucose, each preprandial blood glucose, each postprandial maximum blood glucose, range of increase in postprandial glucose from pre-meal to after breakfast, the area under the blood concentration-time curve >180 mg/dL and percentage of the area under the blood concentration-time curve >180 mg/dL were higher with higher HbA1c. Mean glucose level and pre-breakfast blood glucose level were significant and independent determinants of HbA1c. In Japanese patients treated for type 2 diabetes, the mean amplitude of glycemic excursions did not correlate with HbA1c, making it difficult to assess blood glucose fluctuations using HbA1c. Parameters other than HbA1c are required to evaluate fluctuations in blood glucose level in patients receiving treatment for type 2 diabetes. © 2017 The Authors.

    To compare plasma glucose levels and incidence of hyperglycaemia in the post-operative period after general surgery using fluids with different glucose. A randomised, open-label, non-blind, clinical trial was conducted on patients admitted to Paediatric Intensive Care Unit after elective surgery. The inclusion criteria were from 6 months to 14 years of age, with a weight greater than 6kg, onset glucose level >60mg/dL, and a signed informed consent, with no oral intake and maintenance intravenous fluid therapy using fluids with 3.3% or 5% glucose. Plasma glucose levels were measured before surgery, on admission, and 8, 24, and 48h, with the mean glucose levels and incidence of hyperglycaemia (glucose level >150mg/dL) in both groups being compared. A total of 60 patients received glucose/saline 1/3 (51mEq/L sodium and 33g/L glucose), and 70 glucose/saline 5/0.9% (154mEq/L sodium and 50g/L glucose). Mean glucose levels were higher in the group receiving glucose 5%, with no statistical difference. There was no significant difference in the incidence of hyperglycaemia; 8h: 26% in the 3.3% group vs. 21.3% in the 5% group (P=.63); 24h: 20% vs. 22.7% (P=.8); and 48h: 19% vs. 23.1% (P=.78). The use of fluids with 3.3% glucose in the post-operative period of general surgery maintains mean glucose levels in a similar range to that of patients receiving fluids with 5% glucose, with no difference in the incidence of hyperglycaemia.

  3. Serum adiponectin levels in patients with coronary artery disease

    Fayyaz, I.; Shah, S.I.; Ghani, M.

    2009-01-01

    Adiponectin is an adipocytokine secreted from white adipose tissue. Serum level of adiponectin has been shown to be reduced in several disease states like obesity and diabetes. Hypoadiponectinemia has also been included in the list of newer risk factors for Coronary Artery Disease (CAD). In this analytical cross-sectional study serum adiponectin level was measured by Enzyme Linked Immunosorbant Assay (ELISA) in 60 cases of coronary artery disease (CAD) (both sexes, aged 40-60 yrs) and 60 healthy controls. Low levels of adiponectin were seen in CAD patients as well as controls. These levels were lower as compared to western standards. Our study conforms to the previous observation of lower serum adiponectin levels in South Asians compared to the western standards. Serum adiponectin level should be considered in the laboratory work-up of CAD patients. (author)

    2015-01-01

    Full Text Available Objective. Progranulin (PGRN was recently introduced as a novel marker of chronic inflammatory response in obesity and type 2 diabetes capable of directly affecting the insulin signaling pathway. This study aimed to investigate the correlation between PGRN and type 2 diabetics with microvascular complications. Methods. PGRN serum levels and glucose metabolism related substance were measured in 84 type 2 diabetic patients with or without microangiopathies and 12 health persons. Further analyses of serum PGRN in different stages of diabetic microangiopathies were conducted. Results. Serum levels of PGRN were markedly higher in type 2 diabetic patients with microangiopathies. PGRN serum levels increased with the progress of diabetic microangiopathies with significantly highest values detectable in clinical diabetic nephropathy (CDN and proliferative diabetic retinopathy (PDR groups. Serum PGRN concentrations in all individuals positively and markedly correlated with systolic blood pressure (SBP, diastolic blood pressure (DBP, body mass index (BMI, triglyceride (TG, urinary albumin excretion rate (UAER, blood urea nitrogen (BUN, creatinine (CRE, white blood cell (WBC, disease duration, IL-6, and TNF-α, while correlating negatively and significantly with eGFR. Multiple linear regression analysis showed that only UAER and CRE were independently associated with serum PGRN. Conclusion. PGRN might be considered as a marker for diabetic microangiopathy and its severity.

  10. Modulation of memory with septal injections of morphine and glucose: effects on extracellular glucose levels in the hippocampus.

    McNay, Ewan C; Canal, Clinton E; Sherwin, Robert S; Gold, Paul E

    2006-02-28

    The concentration of glucose in the extracellular fluid (ECF) of the hippocampus decreases substantially during memory testing on a hippocampus-dependent memory task. Administration of exogenous glucose, which enhances task performance, prevents this decrease, suggesting a relationship between hippocampal glucose availability and memory performance. In the present experiment, spontaneous alternation performance and task-related changes in hippocampal ECF glucose were assessed in rats after intraseptal administration of morphine, which impairs memory on a spontaneous alternation task, and after co-administration of intraseptal glucose, which attenuates that impairment. Consistent with previous findings, spontaneous alternation testing resulted in a decrease in hippocampal ECF glucose levels in control rats. However, rats that received intraseptal morphine prior to testing showed memory impairments and an absence of the task-related decrease in hippocampal ECF glucose levels. Intraseptal co-administration of glucose with morphine attenuated the memory impairment, and ECF glucose levels in the hippocampus decreased in a manner comparable to that seen in control rats. These data suggest that fluctuations in hippocampal ECF glucose levels may be a marker of mnemonic processing and support the view that decreases in extracellular glucose during memory testing reflect increased glucose demand during memory processing.

    Apolipoprotein E (ApoE), which has been shown to influence serum lipid parameters, can bind to multiple types of lipids and plays an important role in the metabolism and homeostasis of lipids and lipoproteins. A previous study showed that ApoE concentration significantly affects serum lipid levels independently of ApoE polymorphism. The serum lipid levels were also closely correlated with dietary habits, and Shandong cuisine is famous for its high salt and oil contents, which widely differ among the different areas in China. Therefore, studying the effect of ApoE polymorphism on ApoE concentration and serum lipid levels in Shandong province is very important.A total of 815 subjects including 285 men and 530 women were randomly selected and studied from Jinan, Shandong province. In order to evaluate the association of ApoE polymorphism and serum level on lipid profiles, the ApoE genotypes, as well as levels of fasting serum ApoE and other lipid parameters, were detected in all subjects.The frequency of the ApoE E3 allele was highest (83.1%), while those of E2 and E4 were 9.4% and 7.5%, respectively, which are similar to those in other Asian populations. ApoE2 allele carriers showed significantly increased ApoE levels but lower levels of serum total cholesterol (TC), low-density lipoprotein cholesterol (LDL-C), and Apolipoprotein B (ApoB).We found that ApoE level is influenced by ApoE polymorphism in a gene-dependent manner. The ApoE polymorphism showed different influences on serum lipid parameters with increasing age and body mass index (BMI) in our Shandong Han population.

    The aim of this study is to quantitatively analyze the influence of risk factors on the blood glucose level, and to provide theory basis for understanding the characteristics of blood glucose change and confirming the intervention index for type 2 diabetes. The quantitative method is proposed to analyze the influence of risk factors on blood glucose using back propagation (BP) neural network. Ten risk factors are screened first. Then the cohort is divided into nine groups by gender and age. According to the minimum error principle, nine BP models are trained respectively. The quantitative values of the influence of different risk factors on the blood glucose change can be obtained by sensitivity calculation. The experiment results indicate that weight is the leading cause of blood glucose change (0.2449). The second factors are cholesterol, age and triglyceride. The total ratio of these four factors reaches to 77% of the nine screened risk factors. And the sensitivity sequences can provide judgment method for individual intervention. This method can be applied to risk factors quantitative analysis of other diseases and potentially used for clinical practitioners to identify high risk populations for type 2 diabetes as well as other disease.

    Thioredoxin (Trx) is one of significant antioxidative molecules to diminish oxidative stress. Current evidence suggests that Trx is a potent antioxidant with cytoprotective functions. The aim of our study was to investigate specifically the association between serum Trx levels and acute ischemic stroke (AIS) patients. 198 AIS patients and 75 controls were enrolled to the study. Serum Trx levels were measured using an enzyme-linked immunosorbent assay (ELISA). Stroke severity was assessed with the National Institutes of Health Stroke Scale (NIHSS) score on admission. Clinical endpoint was functional outcome measured by Barthel Index (BI) 3 months after admission. Multivariate binary logistic regression analyses were performed to identify predictors. We found that serum Trx levels were significantly increased in patients as compared to controls. Serum Trx was an independent biomarker to predict ischemic stroke (OR, 1.264; 95% CI, 1.04-1.537; P = 0.019). In addition, there was a negative correlation between NIHSS score at admission and serum Trx levels in cardioembolic stroke patients (r = -0.422; P = 0.013). Furthermore, higher serum Trx levels in AIS patients were associated with favorable functional outcome. Serum Trx was an independent predictor for the functional outcome (OR, 0.862; 95% CI, 0.75-0.991; P = 0.037). Serum Trx might be as a biomarker of cardioembolic stroke severity. Increased serum Trx levels could be a useful tool to predict good prognosis in patients with AIS.

    Full Text Available Objective This study measured serum and follicular fluid (FF levels of biopterin, neopterin, vascular endothelial growth factor (VEGF, and macrophage colony-stimulating factor (M-CSF in patients receiving mild ovarian stimulation for oocyte retrieval. Patients and Methods Infertile patients who underwent ovarian stimulation were divided into the following: Group 1, no oocyte retrieval ( n = 12, and Group 2, retrieval of more than four oocytes ( n = 13. Median total gonadotropin dose in both groups was 150 IU. Biopterin and neopterin levels were measured using high-performance liquid chromatography. VEGF and M-CSF levels were measured by enzyme-linked immunosorbent assay. Results Compared to Group 2, serum and FF levels of neopterin and VEGF and serum levels of M-CSF were significantly increased, and serum and FF levels of biopterin were significantly decreased in Group 1 ( P < 0.05 each. Conclusion Biopterin and neopterin levels showed similar differences in FF and serum of patients with empty follicles. Decreased biopterin and increased neopterin in serum could predict poor oocyte retrieval.

    Osteopontin a matricellular protein has pro-fibrotic effects and binds integrin such as αvβ1 and αvβ3. Vitronectin is one of the integrin αvβ3 ligands and is a multifunctional glycoprotein. The aim of the present study was to evaluate serum osteopontin and vitronectin levels in a cohort of patients with systemic sclerosis (SSc). Eighty-six patients with SSc, 46 patients with systemic lupus erythematosus (SLE), and 38 healthy controls (HC) were enrolled in the study. Serum osteopontin, vitronectin, IL-6, and TGF-β levels were analyzed. Serum osteopontin levels were higher in the SSc and SLE groups compared to the HC group (p < 0.01 and p < 0.001, respectively). However, it was not correlated with disease activity and severity scores in the SSc group. On the other hand, serum vitronectin levels were lower in the SSc group than in the SLE and HC groups (p < 0.001 for both). These results may suggest that osteopontin levels may be increased due to the inflammatory process and osteopontin has not a specific role on fibrosis in SSc. On the other hand, serum vitronectin levels decrease in SSc in contrast to SLE. It may be concluded that the one cause of decreased serum vitronectin levels in SSc may be its accumulation in fibrotic area.

    Inhibin B is a testicular peptide hormone that regulates FSH secretion in a negative feedback loop. In males serum levels of inhibin B are detectable throughout life with prominent changes in the first year of life and during puberty. Serum inhibin B is normally detectable throughout childhood...... normal or near-normal levels are seen in cryptorchidism and disorders with preserved Sertoli cell function in spite of absence of germ cells or impaired androgen biosynthesis or action. During puberty a developmental change in the regulation of serum inhibin B occurs. In contrast to childhood inhibin B...

  1. Serum Renalase Levels Correlate with Disease Activity in Lupus Nephritis.

    Chaojun Qi

    Full Text Available Lupus nephritis (LN is among the most serious complications of systemic lupus erythematosus (SLE, which causes significant morbidity and mortality. Renalase is a novel, kidney-secreted cytokine-like protein that promotes cell survival. Here, we aimed to investigate the relationship of serum renalase levels with LN and its role in the disease progression of LN.For this cross-sectional study, 67 LN patients and 35 healthy controls were enrolled. Seventeen active LN patients who received standard therapies were followed up for six months. Disease activity was determined by the SLE Disease Activity-2000 (SLEDAI-2K scoring system and serum renalase amounts were determined by ELISA. Predictive value of renalase for disease activity was assessed. Furthermore, the expression of renalase in the kidneys of patients and macrophage infiltration was assessed by immunohistochemistry.Serum renalase amounts were significantly higher in LN patients than in healthy controls. Moreover, patients with proliferative LN had more elevated serum renalase levels than Class V LN patients. In proliferative LN patients, serum renalase levels were significantly higher in patients with active LN than those with inactive LN. Serum renalase levels were positively correlated with SLEDAI-2K, 24-h urine protein excretion, ds-DNA and ESR but inversely correlated with serum albumin and C3. Renalase amounts decreased significantly after six-months of standard therapy. The performance of renalase as a marker for diagnosis of active LN was 0.906 with a cutoff value of 66.67 μg/ml. We also observed that the amount of renalase was significantly higher in glomerular of proliferative LN along with the co-expression of macrophages.Serum renalase levels were correlated with disease activity in LN. Serum renalase might serve as a potential indicator for disease activity in LN. The marked increase of glomerular renalase and its association with macrophages suggest that it might play an

    High blood pressure is very prevalent worldwide, as well as vitamin D deficiency. There are several observation data that support the concept that vitamin D is involved in the pathogenesis of hypertension. Also some clinical data demonstrate positive effect of vitamin D therapy on hypertension. We studied serum levels of vitamin D and its association with blood pressure in 30 hypertensive patients and 20 age and socioeconomic status matched healthy controls. There was no statistically significant difference in serum vitamin D levels in the group of patients compared with controls. In patients group, patients with body mass index (BMI) > 30 kg/m 2 showed statistically significant decrease in serum vitamin D levels as compared to those with BMI ≤ 30 kg/m 2 (P = 0.021). There was no significant association between serum vitamin D levels and age, systolic and diastolic blood pressure in the group of patients. A negative correlation between serum vitamin D levels and BMI was found in patients group (P = 0.045). In conclusion, no association between serum levels of vitamin D and blood pressure in hypertensive patients, but it is statistically associated with BMI. Further large scale studies are needed putting in consideration the effect of genetic factor

    Diabetic patients develop hand conditions that are managed with local corticosteroid injections. Injections can result in a transient elevation in serum glucose in diabetic patients. Hemoglobin A1c is the accepted measure of long-term plasma glucose control in diabetics (levels ≥7 percent reflect poor blood glucose control). The purpose of this study was to assess the relationship between hemoglobin A1c levels and increased blood glucose levels after corticosteroid injections. Twenty-five diabetic patients were evaluated prospectively. One milliliter containing 10 mg of triamcinolone acetonide was used. The most recent hemoglobin A1c level and normal average blood glucose levels were obtained. Glucose levels were obtained from patient recall of their daily blood glucose self- monitoring on the day of the injection. Postinjection blood glucose levels were recorded until levels returned to preinjection baseline. Twenty patients (80 percent) had elevation of their blood glucose level from baseline. No patient had elevated blood glucose levels after 5 days. Patients with hemoglobin A1c levels greater than or equal to 7 percent had a higher blood glucose elevation and maintained this for longer than those who had a lower hemoglobin A1c level. Patients in the higher hemoglobin A1c group also had a higher number of hyperglycemic events. There was a strong or moderate correlation between hemoglobin A1c and elevated blood glucose levels during days 1 to 4. Patients with hemoglobin A1c levels greater than or equal to 7 percent have elevations in blood glucose that are higher and last longer than patients with lower levels. Hemoglobin A1c levels can be used to roughly predict the degree of blood glucose elevation after corticosteroid injections into the hands of diabetic patients.

    Glycemic variability is known to induce oxidative stress. We investigated the relationships between glycemic variability and serum bilirubin levels, an endogenous anti-oxidant, in patients with diabetes. A cross-sectional study was carried out with 77 patients with type 2 diabetes who had been recruited to two clinical studies from 2008 to 2014. There were no participants with diseases of the pancreas, liver, biliary tract and chronic renal insufficiency. Glycemic variation was calculated by a continuous glucose monitoring system, and correlation analyses were carried out to evaluate their association with bilirubin levels. Multiple linear regression was carried out to identify independent factors influencing bilirubin levels and glycemic variation. Among the participants, 42.3% were men. The mean (standard deviation) age was 61.5 years (10.4 years), body mass index was 24.2 kg/m 2 (2.8 kg/m 2 ), diabetes duration was 17.7 years (9.5 years), hemoglobin A 1c was 60.7 mmol/mol (7.1 mmol/mol; 7.7 [0.7]%) and bilirubin was 11.8 μmol/L (4.10 μmol/L). Serum bilirubin levels were not different according to age, body mass index and hemoglobin A 1c . However, the mean amplitude of glucose excursion was positively associated with bilirubin levels in women (r = 0.588, P bilirubin and mean amplitude of glucose excursion remained significant (r = 0.566, P bilirubin was an independent determinant for the mean amplitude of glucose excursion in women. 1,5-Anhydroglucitol was also associated with bilirubin levels in women. Bilirubin level within the physiological range might be an independent predictor for glycemic variability in women with type 2 diabetes. © 2016 The Authors.

    The suppressive effect of rice albumin (RA) of 16 kDa on elevation of blood glucose level after oral loading of starch or glucose and its possible mechanism were examined. RA suppressed the increase in blood glucose levels in both the oral starch tolerance test and the oral glucose tolerance test. The blood glucose concentrations 15 min after the oral administration of starch were 144 ± 6 mg/dL for control group and 127 ± 4 mg/dL for RA 200 mg/kg BW group, while those after the oral administration of glucose were 157 ± 7 mg/dL for control group and 137 ± 4 mg/dL for RA 200 mg/kg BW group. However, in the intraperitoneal glucose tolerance test, no significant differences in blood glucose level were observed between RA and the control groups, indicating that RA suppresses the glucose absorption from the small intestine. However, RA did not inhibit the activity of mammalian α-amylase. RA was hydrolyzed to an indigestible high-molecular-weight peptide (HMP) of 14 kDa and low-molecular-weight peptides by pepsin and pancreatin. Furthermore, RA suppressed the glucose diffusion rate through a semipermeable membrane like dietary fibers in vitro. Therefore, the indigestible HMP may adsorb glucose and suppress its absorption from the small intestine.

    2006-09-01

    To examine whether serum adiponectin concentrations were associated with subclinical atherosclerosis assessed as intima media thickness (IMT) in the carotid arteries in Caucasian women with varying degrees of glucose tolerance. From a population-based cohort of 64-year-old Swedish women, 533 subjects with type 2 diabetes (DM2, n=177), impaired glucose tolerance (IGT; n=178) or normal glucose tolerance (NGT, n=178) were recruited. Anthropometrics, usual cardiovascular risk factors were examined and ultrasound examination of the carotid arteries was performed. Women with low adiponectin concentrations were characterized by thick IMT, higher prevalence of DM2, history of previous myocardial infarction, angina pectoris, anti-hypertensive treatment and high body mass index (BMI), waist circumference, plasma insulin, serum triglycerides, fasting glucose, HbA1c, and low serum HDL cholesterol levels. Carotid IMT correlated with HbA1c (r=0.24, PDM2 (r=0.16, P<0.001), systolic blood pressure (r=0.16, P<0.001), blood glucose (r=0.16, P<0.001), triglycerides (r=0.15, P<0.001), and reversely to adiponectin (r=-0.11, P=0.01), HDL cholesterol (r=-0.13, P=0.004), and alcohol intake (r=-0.087, P<0.05). A more detailed analysis of underlying associations was difficult due to a high co-linearity between these variable. Low serum adiponectin concentrations were associated with increased carotid artery IMT, and several risk factors for cardiovascular diseases, mainly those constituting the metabolic syndrome.

  11. Serum levels of FGF-21 are increased in coronary heart disease patients and are independently associated with adverse lipid profile.

    Full Text Available BACKGROUND: Fibroblast growth factor 21 (FGF-21 is a metabolic regulator with multiple beneficial effects on glucose homeostasis and lipid metabolism in animal models. The relationship between plasma levels of FGF-21 and coronary heart disease (CHD in unknown. METHODOLOGY/PRINCIPAL FINDINGS: This study aimed to investigate the correlation of serum FGF-21 levels and lipid metabolism in the patients with coronary heart disease. We performed a logistic regression analysis of the relation between serum levels of FGF-21 and CHD patients with and without diabetes and hypertension. This study was conducted in the Departments of Endocrinology and Cardiovascular Diseases at two University Hospitals. Participants consisted of one hundred and thirty-five patients who have been diagnosed to have CHD and sixty-one control subjects. Serum FGF-21 level and levels of fasting blood glucose; triglyceride; apolipoprotein B100; HOMA-IR; insulin; total cholesterol; HDL-cholesterol; LDL-cholesterol; and C-reactive protein were measured. We found that median serum FGF-21 levels were significantly higher in CHD than that of control subjects (P<0.0001. Serum FGF-21 levels in CHD patients with diabetes, hypertension, or both were higher than that of patients without these comorbidities. Serum FGF-21 levels correlated positively with triglycerides, fasting blood glucose, apolipoprotein B100, insulin and HOMA-IR but negatively with HDL-C and apolipoprotein A1 after adjusting for BMI, diabetes and hypertension. Logistic regression analysis demonstrated that FGF-21 showed an independent association with triglyceride and apolipoprotein A1. CONCLUSIONS/SIGNIFICANCE: High levels of FGF-21 are associated with adverse lipid profiles in CHD patients. The paradoxical increase of serum FGF-21 in CHD patients may indicate a compensatory response or resistance to FGF-21.

    Cao Huiling; Guo Dongmei

    2004-01-01

    Objective: To evaluate the relationship between serum levels of leptin and microangiopathy in patients with type 2 diabetes. Methods: Fasting serum leptin (with RIA), insulin (with RIA) and fasting blood glucose (with oxidase method) levels were measured in 30 controls, 30 diabetic patients without microangiopathy and 30 patients with diabetic microangiopathy. Correlations between levels of serum leptin and other parameters were analyzed. Results: The levels of serum leptin in controls, diabetic patients without microangiopathy and patients with diabetic microangiopathy were (7.20 ± 2.11) μg/L, (7.95 ± 3.78) μg/L and (19.26 ± 4.37) μg/L respectively. The patients with diabetic microangiopathy had higher serum leptin levels than those in the diabetic patients without microangiopathy (t=2.18, P<0.05) and controls (t = 2.71, P<0.01), while the serum leptin levels in diabetic patients without microangiopathy were not significantly different from those in controls. The serum leptin levels were positively correlated with BMI and FINS (r=0.29, P<0.05; r=0.34, P<0.01). Conclusion: Serum leptin levels were elevated in patients with diabetic microangiopathy and were closely related with the development of diabetic microangiopathy. (authors)

    Full Text Available Aim: Several epidemiological studies have shown an inverse correlation between allergy and brain cancer. The purpose of this study was to compare the serum IgE levels between patients with gliomas and nonglial tumors and their possible prognostic role. Methods: A total of 84 patients with intracranial tumors were included in this study. At clinical presentation, estimation of serum IgE levels was assessed by nephelometry. Detailed information regarding the history of allergies was collected by interview. Results: Of the 84 cases, 42 were gliomas, 23 were meningiomas, 16 were metastases and 3 were primary central nervous system lymphomas. Patients with high-grade glioma had lower IgE levels than patients with low-grade glioma. Patients with glioma and meningioma had statistical significant lower serum IgE levels than patients with metastases. Patients with glioblastoma with serum IgE levels greater than 24 U/mL had a better survival. Conclusion: Patients with glioma and meningioma had lower IgE levels than patients with metastatic lesions. A prognostic role of serum IgE levels was found in glioblastoma. Further studies in larger patient series are required in order to verify our preliminary observations.

    Full Text Available Introduction : Systemic sclerosis (SSc is achronic connective tissue disease characterized by microangiopathy with inadequate angiogenesis. Angiostatin (AS is a potent antiangiogenic factor specifically inhibiting proliferation and inducing apoptosis of vascular endothelial cells. Aim : To evaluate the level of angiostatin in the serum of patients with SSc. Material and methods : Serum levels of AS were measured in 20 SSc patients and 12 healthy controls. Results : A statistically significant difference in the serum levels of AS in SSc patients was observed compared to the control group (636.51 vs. 869.20 ng/ml; p = 0.012. Significant correlations between limited and disseminated SSc (lSSc/dSSc were not found, however, a difference between lSSc and the control group was demonstrated (620.00 vs. 869.20 ng/ml; p = 0.011. The serum level of AS was not associated positively with organ changes caused by SSc. However, a statistically significant lower serum level of AS was observed in patients with SSc and no esophageal (p = 0.008 or pulmonary changes (p = 0.007 compared to the control group. Conclusions : Our results reveal significant differences in AS level in SSc patients compared to the healthy controls, and suggest that a low level of AS may occur as a result of impaired angiogenesis.

    2001-01-01

    In order to study the serum osteocalcin (OC) level in hyperthyroidism, serum osteocalcin, FT 3 , FT 4 and TSH were measured by radioimmunoassay in 87 patients with hyperthyroidism and 52 healthy volunteers. The results indicated that the serum osteocalcin level was decreased with age increasing in healthy volunteers and there was no significant difference in sex (P > 0.05). Serum concentration of OC was significantly higher in untreated hyperthyroid patients than that in healthy volunteers (P 3 , FT 4 (FT 3 :r 0.84 - 0.27, P 4 :r = 0.58 - 0.29, P < 0.01), but not with TSH. Conclusion: Thyroid hormones might speed up bone turnover directly with increased bone resorption to induce bone mass loss. These results indicate that OC is a highly sensitive marker for altered bone metabolism in hyperthyroidism

    Serum Brain-Derived Neurotrophic Factor (BDNF) levels are associated with neurotransmission and cognitive functions. The goal of this study was to examine the effect of general anesthesia on BDNF levels. It was also to reveal whether this effect had a relationship with the surgical stress response or not. The study included 50 male patients, age 20-40, who were scheduled to have inguinoscrotal surgery, and who were in the ASA I-II risk group. The patients were divided into two groups according to the anesthesia techniques used: general (GA) and spinal (SA). In order to measure serum BDNF, cortisol, insulin and glucose levels, blood samples were taken at four different times: before and after anesthesia, end of the surgery, and before transferal from the recovery room. Serum BDNF levels were significantly low (p BDNF and the stress hormones. Our findings suggested that general anesthetics had an effect on serum BDNF levels independent of the stress response. In future, BDNF could be used as biochemical parameters of anesthesia levels, but studies with a greater scope should be carried out to present the relationship between anesthesia and neurotrophins.

  18. Intracerebroventricular Kainic Acid-Induced Damage Affects Blood Glucose Level in d-glucose-fed Mouse Model.

    Kim, Chea-Ha; Hong, Jae-Seung

    2015-03-01

    We have previously reported that the intracerebroventricular (i.c.v.) administration of kainic acid (KA) results in significant neuronal damage on the hippocampal CA3 region. In this study, we examined possible changes in the blood glucose level after i.c.v. pretreatment with KA. The blood glucose level was elevated at 30 min, began to decrease at 60 min and returned to normal at 120 min after D-glucose-feeding. We found that the blood glucose level in the KA-pretreated group was higher than in the saline-pretreated group. The up-regulation of the blood glucose level in the KA-pretreated group was still present even after 1~4 weeks. The plasma corticosterone and insulin levels were slightly higher in the KA-treated group. Corticosterone levels decreased whereas insulin levels were elevated when mice were fed with D-glucose. The i.c.v. pretreatment with KA for 24 hr caused a significant reversal of D-glucose-induced down-regulation of corticosterone level. However, the insulin level was enhanced in the KA-pretreated group compared to the vehicle-treated group when mice were fed with D-glucose. These results suggest that KA-induced alterations of the blood glucose level are related to cell death in the CA3 region whereas the up-regulation of blood glucose level in the KA-pretreated group appears to be due to a reversal of D-glucose feeding-induced down-regulation of corticosterone level.

    BACKGROUND/OBJECTIVES Curcumin, an active ingredient in turmeric, is highly consumed in South Asia. However, curry that contains turmeric as its main spice might be the major source of curcumin in most other countries. Although curcumin consumption is not as high in these countries as South Asia, the regular consumption of curcumin may provide a significant health-beneficial effect. This study evaluated whether the moderate consumption of curry can affect blood glucose and lipid levels that b...

  20. Reduced total serum bilirubin levels are associated with ulcerative colitis.

    Kathleen M Schieffer

    Full Text Available Chronic inflammation associated with inflammatory bowel disease (IBD results in increased oxidative stress that damages the colonic microenvironment. Low levels of serum bilirubin, an endogenous antioxidant, have been associated with increased risk for Crohn's disease (CD. Therefore, the aim of this study was to examine whether total serum bilirubin levels are associated with ulcerative colitis (UC. We identified a retrospective case-control population (n = 6,649 from a single tertiary care center, Penn State Hershey Medical Center (PSU and a validation cohort (n = 1,996 from Virginia Commonwealth University Medical Center (VCU. Cases were age- and sex-matched to controls (PSU: CD n = 254, UC n = 187; VCU: CD n = 233, UC n = 124. Total serum bilirubin levels were obtained from de-identified medical records and segregated into quartiles. Logistic regression analysis was performed on each quartile of total serum bilirubin compared to the last quartile (highest bilirubin levels to determine the association of total serum bilirubin with UC. Similar to CD patients, UC patients demonstrated reduced levels of total serum bilirubin compared to controls at PSU and VCU. The lowest quartile of total serum bilirubin was independently associated with UC for the PSU (OR: 1.98 [95% CI: 1.09-3.63] and VCU cohorts (OR: 6.07 [95% CI: 3.01-12.75]. Lower levels of the antioxidant bilirubin may reduce the capability of UC patients to remove reactive oxygen species leading to an increase in intestinal injury. Therapeutics that reduce oxidative stress may be beneficial for these patients.

    2002-01-01

    To study the change and the correlation of serum soluble vascular cell adhesion molecule-1 (sV-CAM-1) levels with diabetic retinopathy in type 2 diabetic patients, serum sVCAM-1 levels were measured in duplicate by ELISA in 85 type 2 diabetic patients; fundus examination was performed by an ophthalmologist using ophthalmoscope or fundus fluorescein angiography, and the findings were graded as: no signs of diabetic retinopathy (NDR), background diabetic retinopathy (BDR) and proliferative diabetic retinopathy (PDR). Serum sVCAM-1 levels were significantly higher in the PDR and BDR groups than those in the control and NDR groups respectively (P<0.01). NDR group showed significantly increased serum sVCAM-levels compared with control group (P<0.01). In contrast, serum sVCAM-1 levels were not related to the presence of blood glucose, serum insulin levels or known diabetic duration. Authors' results suggest that serum sVCAM-1 might be implicated in the development of the diabetic retinopathy, and could assess the severity of diabetic retinopathy. The measurement of serum sVCAM-1 levels in 2 type diabetic patients may be clinically useful for early diagnosis or treatment of diabetic retinopathy

    Full Text Available Introduction:The present study evaluated the hypoglycemic perspectives and weight loss significance of dietary fiber. Dietary fiber was supplemented in commercial wheat flour (atta for the preparation of chapaties, a staple diet of South Asia. Male Sprague Dawley rats (n = 100 were randomly divided into 4 diet groups (n = 25 per group. The control group was fed basal diet that included commercial wheat flour chapati, cornstarch, corn oil, salt and vitamin mixture in such a way that 10% of the protein was available from the final diet. To the basal diet of other 3 groups, chapaties supplemented with 2% guar gum (GG 2%, 3% guar gum (GG 3% and 5% chickpea + 1% guar gum (CP5%+GG1% were added, respectively. All diets were fed to the rats for a period of 8 weeks to perceive the impact of respective compositions. Rats fed on CP 5% + GG1%, showed maximum glucose reduction (14.57% followed by GG 3% (11.64% and GG 2% (9.60% as compared to control diet. Likewise, rats fed on 3% GG showed maximum decline (7.90% in body weight. It was concluded that chapaties prepared from selected treatments provide an additional dietary fiber that could be supportive for diabetic and obese individuals.Results:The results indicated that addition of dietary fiber influenced the physical characteristics of chapati non-significantly. Maximum glucose concentration was found to be 112.50 mg/dL in control group followed by 101.70 and 99.41 mg/dL in groups fed on guar gum 2% and guar gum 3%, respectively. Lowest glucose concentration (96.11 mg/dL was observed in rats fed on the combination of chickpea 5 %+ guar gum 1%. Maximum serum protein concentration was found to be 6.39 g/dL in rats fed on combination of chickpea 5 % + guar gum 1% whilst the remaining three groups showed non significant variations with respect to each other. Means for serum Functional Foods in Health and Disease 2011; 8:261-278 protein were 6.33, 6.30 and 6.32 g/dL for control, guar gum 3%, and guar gum 2

    2011-01-01

    Serum selenium has been implicated as a risk factor for lung cancer, but the issue remains unsettled. We tested in a cohort of 3,333 males aged 53 to 74 years the hypothesis that a low serum selenium would be associated with an increased risk of lung cancer mortality.During 16 years, 167 subjects(5.......1%) died from lung cancer; 48 males (5.0%) among males with low serum selenium, 0.4-1.0 μmol·l(-1), n=965, 57 males (5.1%) among males with medium serum selenium, 1.1-1.2 μmol·l(-1), n=1,141, and 62 males (5.1%) among males with high serum selenium, 1.3-3.0 μmol·l(-1), n=1,227. After adjustment for age...... (chronic bronchitis and peak flow), referencing the lowest level of serum selenium HRs were 1.17(0.79-1.75), and 1.43(0.96-2.14), respectively. Among heavy smokers a high serum selenium was associated with a significantly increased risk of lung cancer mortality after taking into account all potential...

    El-Mahdy, A.A.; El-Sherbiny, E.M.; Bayomi, M.M.

    2005-01-01

    The present study was undertaken to investigate the harmful effect of protein deficient diet on some biochemical activities in serum of female rats. Protein malnutrition is a well known socioeconomic problem in different parts of the world. Many studies were investigated on the biological parameters following protein malnutrition in human and experimental animals. Forty albino female rats were divided into 3 groups. The first group (10 rats) fed 18% protein diet and served as normal control and the other two groups, each contains 15 rats, fed 5% protein for 21 and 45 days, respectively, and served as malnourished groups. The results showed significant decrease in total body weight, serum glucose, insulin and estradiol levels in the third group as well as decrease in the total cholesterol, HDL-cholesterol, LDL-cholesterol and VLDL-cholesterol and triglycerides concentrations that compared to normal control rats

    2015-01-01

    Objectives: The aim of present study was to investigate serum homocysteine levels in apparently healthy vegetarians and ominvores in Mithi, district Tharparker, Sindh, Pakistan. Methods: This study was conducted in the Department of Biochemistry, Basic Medical Sciences Institute (BMSI), Jinnah Postgraduate Medical Center (JPMC), Karachi and blood samples were collected from Mithi, district Tharparker, Sindh, Pakistan, in 2012. One hundred vegetarian and one hundred omnivores (age ranging from 20-40 years) were enrolled for this study. Serum homocysteine levels were measured by the chemiluminescence enzyme immunoassay method. Results: Serum homocysteine (Hcy) level was considerably higher (p15µmol/L compared to omnivores 6%, (p15µmol/L serum Hcy level in vegetarian group and 6.9% male and 3.5% females had >15µmol/L serum Hcy level in omnivores group, but the difference was not significant in any group. Conclusion: Vegetarians are more prone to develop hyperhomocysteinemia, so they are at high risk to develop cardiovascular disease. PMID:25878628

    Jawed, S.; Khawaja, T.F.; Sultan, M.A.; Ahmad, S.

    2005-01-01

    Patient with arterial hypertension and no definable cause are said to have essential, primary or idiopathic hypertension. A total of 100 patients suffering from essential hypertension and 100 control subjects with almost same mean age and sex distribution were enrolled in this study. Levels of serum uric acid, total cholesterol, TG, and HDL-c were determined by enzymatic colorimetric method. Serum LDL-c and VLDL-c was calculated by using Friedewald and Wilson's formulae. The study was aimed to find out the levels of serum uric acid and lipid profile in patients with essential hypertension and to compare them with levels of normal healthy individuals. Results show increased level of serum uric acid and lipid parameters except for HDL-c, which was significantly, decreased in patients with essential hypertension as compared to the control subjects. Variations in aforementioned parameters were also observed on comparing the obese and the non-obese patients. It can be concluded from the present study that the essential hypertension is associated with abnormalities in the levels of serum uric acid and lipid profile. (author)

    samples from 275 high-risk melanoma patients enrolled in the Nordic Adjuvant IFN Melanoma trial were analyzed for circulating OPN concentrations and OPN promoter polymorphisms in position -443. The potential relation between serum OPN levels, the genotypes and survival in non-treated patients and patients...... receiving adjuvant IFN-α was investigated. Although slightly better survival was observed in the treated patients that had high levels of OPN, the difference was not statistically significant. In conclusion, serum OPN (its level or the genotype) cannot distinguish melanoma patients with poor prognosis...

  8. Thyroid iodine uptake and serum triiodothyronine level in eldery subjects

    Paradowski, L.; Dolinska, G.; Knapik, Z.; Rynowiecka, M.

    1980-01-01

    Iodine uptake by the thyroid and serum triiodothyronine (T 3 ) level in subjects aged from 65 to 93 years were determined. Low T 3 level and normal uptake of inorganic iodine by the thyroid were found. In the light of these results it is suggested that normal accumulation of inorganic iodine and low production of T 3 are characteristic features of euthyroidism in elderly subjects. It is believed that the function of the thyroid is expressed better by determination of the serum levels of thyroid hormones than determination of the uptake of radioactive iodine. Elaboration of standard normal values which would take into account abnormalities encountered in old age is postulated. (author)

    Taylor, C B; Allen, E S; Mikkelson, B; Kang-Jey, H

    1976-10-01

    Serum cholesterol levels and dietary habits were surveyed in 27 male and 34 female Seventh-day Adventist. All subjects studied were lacto-ovo-vegetarians and a few consumed some meat products. Their serum cholesterol levels, significantly lower than those of the United States general population, showed no sex difference but increased with age and were higher in overweight males. Their levels, however, were much higher than those of true vegetarians which was most likely attributable to their consumption, even though to a limited acount, of dairy foods.

    Seifi S, Mokhtari A

    2008-07-01

    Full Text Available "nBackground: The annual amount of mortality in ESRD exceeds the expectation and represents the recent evidences of the inflammation as its etiology. The etiology of inflammation is not clearly known. Chronic inflammation is a dominant occurrence of ESRD which increases the risk of atherosclerosis, malnutrition and peripheral vascular disease. Inflammatory responses are orchestrated by cytokines. Some of the proinflammatory cytokines like IL-6 have a crucial role in this phenomenon. The IL-6 and its receptor activity is up regulated in ESRD patients and the increased level of IL-6 predicts cardiovascular mortality and morbidity in normal and CRF patients. This study devotes itself to determining the serum level of IL-6 and factors affecting it in patients undergoing chronic hemodialysis in Imam Khomeini Hospital which can represent the Iranian Society. By identifying factors affecting the serum level of IL-6 and high-risk patients we can provide treatment possibilities, a decrease in mortality and an improvement in its prognosis. "n"nMethods: In this study 42 patients in Imam Dialysis Center were chosen and their serum IL-6 levels were measured at 2 times at three month interval and at the same time blood sample analysis were done for the following: Alb CPR, Ca, P, PTH, TIBC, Ferritin, TG, Chol, LDL, HDL, Uric Acid, Hb, WBC and urea."n"nResults: The mean serum level of IL-6 in hemodialysis patients was 6.35±4.47pg/ml (minimum: 0.55, maximum: 18.25 with the normal range of 1.3±3.2pg/ml."n"nConclusions: The IL-6 level was higher than normal range in the 52% of the patients. The serum IL-6 level had a significant correlations with CPR, Ferritin, TIBC, WBC and their serum IL-6 level was significantly higher in patients with hypertension, but no significant correlation was observed between other parameters and IL-6

    Background and Purpose Bronchial asthma (BA) is a chronic airway disease characterized by airway hyperresponsiveness and remodeling, which are intimately linked to chronic airway inflammation. Reactive oxygen species (ROS) such as hydrogen peroxide are generated by inflammatory cells that are involved in the pathogenesis of BA. However, the role of ROS in the management of BA patients is not yet clear. We attempted to determine the role of ROS as a biomarker in the clinical setting of BA. Subjects and Methods We enrolled patients with BA from 2013 through 2015 and studied the degrees of asthma control, anti-asthma treatment, pulmonary function test results, fractional exhaled nitric oxide (FeNO), serum reactive oxygen metabolite (ROM) levels, and serum levels of interleukin (IL)-6 and IL-8. Results We recruited 110 patients with BA. Serum ROM levels correlated with white blood cell (WBC) count (rs = 0.273, p = 0.004), neutrophil count (rs = 0.235, p = 0.014), CRP (rs = 0.403, p < 0.001), and IL-6 (rs = 0.339, p < 0.001). Serum ROM levels and IL-8 and CRP levels negatively correlated with %FEV1 (rs = -0.240, p = 0.012, rs = -0.362, p < 0.001, rs = -0.197, p = 0.039, respectively). Serum ROM levels were significantly higher in patients who experienced severe exacerbation within 3 months than in patients who did not (339 [302–381] vs. 376 [352–414] CARR U, p < 0.025). Receiver-operating characteristics analysis showed that ROM levels correlated significantly with the occurrence of severe exacerbation (area under the curve: 0.699, 95% CI: 0.597–0.801, p = 0.025). Conclusions Serum levels of ROM were significantly associated with the degrees of airway obstruction, WBC counts, neutrophil counts, IL-6, and severe exacerbations. This biomarker may be useful in predicting severe exacerbations of BA. PMID:27776186

  13. Shikonin increases glucose uptake in skeletal muscle cells and improves plasma glucose levels in diabetic Goto-Kakizaki rats.

    Anette I Öberg

    Full Text Available BACKGROUND: There is considerable interest in identifying compounds that can improve glucose homeostasis. Skeletal muscle, due to its large mass, is the principal organ for glucose disposal in the body and we have investigated here if shikonin, a naphthoquinone derived from the Chinese plant Lithospermum erythrorhizon, increases glucose uptake in skeletal muscle cells. METHODOLOGY/PRINCIPAL FINDINGS: Shikonin increases glucose uptake in L6 skeletal muscle myotubes, but does not phosphorylate Akt, indicating that in skeletal muscle cells its effect is medaited via a pathway distinct from that used for insulin-stimulated uptake. Furthermore we find no evidence for the involvement of AMP-activated protein kinase in shikonin induced glucose uptake. Shikonin increases the intracellular levels of calcium in these cells and this increase is necessary for shikonin-mediated glucose uptake. Furthermore, we found that shikonin stimulated the translocation of GLUT4 from intracellular vesicles to the cell surface in L6 myoblasts. The beneficial effect of shikonin on glucose uptake was investigated in vivo by measuring plasma glucose levels and insulin sensitivity in spontaneously diabetic Goto-Kakizaki rats. Treatment with shikonin (10 mg/kg intraperitoneally once daily for 4 days significantly decreased plasma glucose levels. In an insulin sensitivity test (s.c. injection of 0.5 U/kg insulin, plasma glucose levels were significantly lower in the shikonin-treated rats. In conclusion, shikonin increases glucose uptake in muscle cells via an insulin-independent pathway dependent on calcium. CONCLUSIONS/SIGNIFICANCE: Shikonin increases glucose uptake in skeletal muscle cells via an insulin-independent pathway dependent on calcium. The beneficial effects of shikonin on glucose metabolism, both in vitro and in vivo, show that the compound possesses properties that make it of considerable interest for developing novel treatment of type 2 diabetes.

    Duan Yangqiang; Wang Zuobing; Yu Hui

    2012-01-01

    Objective: To explore the relationship between serum C-reactive protein (CRP), adiponectin (APN), leptin (Leptin) levels, insulin resistance index (HOMA-IR) and type 2 diabetes mellitus (T2DM) disease susceptibility. Methods: The plasma leptin and insulin (FINS) levels in the DM patients were determined by RIA, and the serum ANP levels were determined by ELSIA. The CRP, conventional serum fasting plasma glucose (FPG) levels were determine by automatic biochemistry analyzer. The insulin resistance index (HOMA-IR, FPG x FINS/22.5) was calculated. The result was analyzed with normal healthy control group. Results: The serum CRP and leptin, HOMA-IR levels in T2DM group were significantly higher than that of in control group (P< 0.01), and the serum ANP was significantly lower than in control group (P<0.01). The HOMA-IR in T2DM was positively correlated with serum CRP (r= 0.36, P<0.05) and leptin(r= 0.39, P<0.05), and was negatively correlated with serum APN (r=0.32, P<0.05). Conclusion: The high serum CRP and leptin and low APN levels hyperlipidaemia might be factors for diabetes, and their metabolic disorders may be closely related with insulin resistance in patients with type 2 diabetes.

    2014-01-01

    Full Text Available Background. Serum ghrelin levels may be related to metabolic and clinical changes in patients with psoriasis. Objective. This study was performed to determine the possible effects of serum ghrelin in patients with psoriasis. Methods. The study population consisted of 25 patients with plaque psoriasis. The patients were questioned with regard to age, gender, age of onset, duration of disease, height, weight, and body mass index (BMI. In addition, fasting blood sugar, triglyceride, cholesterol levels, insulin, and ghrelin levels were measured. Results. The mean serum ghrelin level was 45.41 ± 22.41 in the psoriasis group and 29.92 ± 14.65 in the healthy control group. Serum ghrelin level was significantly higher in the psoriasis group compared with the controls (P=0.01. The mean ghrelin level in patients with a lower PASI score was significantly higher than in those with a higher PASI score (P=0.02. Conclusion. The present study was performed to determine the effects of ghrelin in psoriasis patients. We found a negative correlation between severity of psoriasis and ghrelin level. Larger and especially experimental studies focusing on correlation of immune system-ghrelin levels and severity of psoriasis may be valuable to clarify the etiopathogenesis of the disease.

  17. Serum Albumin Levels and Economic Status in Japanese Older Adults.

    Asami Ota

    Full Text Available Low serum albumin levels are associated with aging and medical conditions such as cancer, liver dysfunction, inflammation, and malnutrition and might be an independent predictor of long-term mortality in healthy older populations. We tested the hypothesis that economic status is associated with serum albumin levels and explained by nutritional and health status in Japanese older adults.We performed a cross-sectional analysis using data from the Japan Gerontological Evaluation study (JAGES. The study participants were 6528 functionally independent residents (3189 men and 3339 women aged ≥65 years living in four municipalities in Aichi prefecture. We used household income as an indicator of economic status. Multiple linear regression was used to compare serum albumin levels in relation to household income, which was classified as low, middle, and high. Additionally, mediation by nutritional and health-related factors was analyzed in multivariable models.With the middle-income group as reference, participants with low incomes had a significantly lower serum albumin level, even after adjustment for sex, age, residential area, education, marital status, and household structure. The estimated mean difference was -0.17 g/L (95% confidence interval, -0.33 to -0.01 g/L. The relation between serum albumin level and low income became statistically insignificant when "body mass index", "consumption of meat or fish", "self-rated health", "presence of medical conditions", "hyperlipidemia", or "respiratory disease "was included in the model.Serum albumin levels were lower in Japanese older adults with low economic status. The decrease in albumin levels appears to be mediated by nutrition and health-related factors with low household incomes. Future studies are needed to reveal the existence of other pathways.

    2005-09-01

    Full Text Available Background: The etiology of multiple sclerosis (MS, a chronic demyelinative disease-is unknown. The damage of blood–brain barrier (BBB vasculature is a characteristic of MS and Homocystein (Hcy can damage BBB, then increase in total Hcy may be important in MS pathogenesis. The aim of this study was to compare the serum level of total Hcy in MS patients with control group. Methods: In a case control study, serum level of total Hcy measured in 35 MS patient and compared with 30 healthy matched controls. All patients had definitive MS according to Poser criteria, without history of myocardial infarction, stroke, neuropathy, transient ischemic attack, homocystinuria or renal failure. Results: The serum concentration of total homocystein was significantly higher in multiple sclerosis patients than healthy controls. The mean total Hcy level was 17.92± 6.9 mmol/lit in cases and 14.6±2.92 mmol/lit in controls (P=0.013. Conclusion: Serum total Homocystein may have a role in MS pathogenesis and reduction of it should be studied moreover. Key words: Multiple Sclerosis, Homocystein, Serum level

  19. A multivariate analysis of serum nutrient levels and lung function

    Smit Henriette A

    2008-09-01

    Full Text Available Abstract Background There is mounting evidence that estimates of intakes of a range of dietary nutrients are related to both lung function level and rate of decline, but far less evidence on the relation between lung function and objective measures of serum levels of individual nutrients. The aim of this study was to conduct a comprehensive examination of the independent associations of a wide range of serum markers of nutritional status with lung function, measured as the one-second forced expiratory volume (FEV1. Methods Using data from the Third National Health and Nutrition Examination Survey, a US population-based cross-sectional study, we investigated the relation between 21 serum markers of potentially relevant nutrients and FEV1, with adjustment for potential confounding factors. Systematic approaches were used to guide the analysis. Results In a mutually adjusted model, higher serum levels of antioxidant vitamins (vitamin A, beta-cryptoxanthin, vitamin C, vitamin E, selenium, normalized calcium, chloride, and iron were independently associated with higher levels of FEV1. Higher concentrations of potassium and sodium were associated with lower FEV1. Conclusion Maintaining higher serum concentrations of dietary antioxidant vitamins and selenium is potentially beneficial to lung health. In addition other novel associations found in this study merit further investigation.

    Andries, Alin; Niemeier, Andreas; Støving, Rene K.; Abdallah, Basem M.; Wolf, Anna-Maria; Hørder, Kirsten; Kassem, Moustapha

    2012-01-01

    Objective. Recent data suggest that fetal antigen (FA1) is linked to disorders of body weight. Thus, we measured FA1 serum levels in two extreme nutritional states of morbid obesity (MO) and anorexia nervosa (AN) and monitored its response to weight changes. Design. FA1 and insulin serum concentrations were assessed in a cross-sectional study design at defined time points after gastric restrictive surgery for 25 MO patients and 15 women with AN. Results. Absolute FA1 serum levels were within the assay normal range and were not different between the groups at baseline. However, the ratio of FA1/BMI was significantly higher in AN. FA1 was inversely correlated with BMI before and after weight change in AN, but not in MO patients. In addition, MO patients displayed a significant concomitant decrease of FA1 and insulin with the first 25% of EWL, while in AN patients a significant increase of FA1 was observed in association with weight gain. Conclusion. FA1 is a sensitive indicator of metabolic adaptation during weight change. While FA1 serum levels in humans generally do not correlate with BMI, our results suggest that changes in FA1 serum levels reflect changes in adipose tissue turnover. PMID:22844611

    Bagni, B.; Feggi, L.M.; Prandini, N.; Pasini, S.; Mollica, G.

    1987-01-01

    The tumor marker CA-125 is an embrional glycoprotein detectable in tissues derived from celomatic epitelium. Serum Ca-125 was determined by RIA in 66 patients with various ovarian pathologies (16 malignant at stage III-IV and 50 benign). Six patients with ovarian carcinoma were monitored during the first week after surgery and chemiotherapy for a total of 150 days of treatment. It has been observed that CA-125 serum level is consistently above the normal range (>35 U/ml) in all malignant diseases. In benign pathology, levels above the normal were found to be represented almost exclusively by ovarian endometriosis. Furthermore, the results demonstrate that chemiotherapy alone is capable of lowering CA-125 serum levels. This tumor marker may be of great advantage in diagnosis and follow-up of ovarian malignancy

    Full Text Available Introduction: Endostatin is a C-­terminal proteolytic fragment of collagen XVIII and, as with angiostatin and thrombospondin, is known as an anti­angiogenic agent. The aim of this study was to assess the level of serum endostatin in patients with oral squamous cell carcinoma (SCC, and its association with the clinicopathological characteristics of the tumor.   Materials and Methods:  Using an enzyme-linked immunosorbent assay (ELISA kit, we investigated the circulating levels of endostatin in the blood serum of 45 patients with oral SCC and 45 healthy controls.   Results: The mean level of serum endostatin in patients was significantly lower (68.8±85 ng/ml than in healthy controls (175.6±73 ng/ml (P

  4. Serum Phthalate and Triclosan Levels Have Opposing Associations With Risk Factors for Gestational Diabetes Mellitus

    Benjamin G. Fisher

    2018-03-01

    Full Text Available Certain phthalates and bisphenol A (BPA have been associated with insulin resistance and type 2 diabetes in non-pregnant adults, but studies of gestational diabetes mellitus (GDM have reported conflicting results for phthalates and no associations with BPA. Our aim was to investigate the relationship between maternal serum levels of phthalate metabolites and phenols at 10–17 weeks of gestation and glucose homeostasis at 28 weeks of gestation. 232 women aged ≥16 years without type 1 or 2 diabetes with singleton male pregnancies were recruited from a single UK maternity centre between 2001 and 2009 as part of a prospective observational study (Cambridge Baby Growth Study. Serum levels of 16 phthalate metabolites and 9 phenols (including BPA were measured using liquid chromatography/tandem mass spectrometry. Oral glucose tolerance tests were performed at 28 weeks. 47/232 (20.3% women had GDM. First-trimester triclosan (TCS was inversely associated with incident GDM (adjusted odds ratio per log increase in concentration 0.54, 95% confidence interval 0.34–0.86, p = 0.010. Amongst women without GDM, first-trimester mono-(2-ethylhexyl phthalate and mono(carboxyisooctyl phthalate levels were positively associated with 120-min plasma glucose (adjusted β 0.268 and 0.183, p = 0.0002 and 0.010, respectively in mid-pregnancy. No other monotonic associations were detected between phthalate or phenol levels and fasting or stimulated plasma glucose, β-cell function, insulin resistance, or 60-min disposition index. Our results support a glycaemia-raising effect of phthalates during pregnancy, consistent with findings in non-pregnant populations and suggest a possible protective effect of exposure to TCS against GDM.

    Glycated albumin (GA) is an indicator of glycemic control, which has some specific characters in comparison with HbA1c. Since glucocorticoids (GC) promote protein catabolism including serum albumin, GC excess state would influence GA levels. We therefore investigated GA levels in patients with Cushing's syndrome. We studied 16 patients with Cushing's syndrome (8 patients had diabetes mellitus and the remaining 8 patients were non-diabetic). Thirty-two patients with type 2 diabetes mellitus and 32 non-diabetic subjects matched for age, sex and BMI were used as controls. In the patients with Cushing's syndrome, GA was significantly correlated with HbA1c, but the regression line shifted downwards as compared with the controls. The GA/HbA1c ratio in the patients with Cushing's syndrome was also significantly lower than the controls. HbA1c in the non-diabetic patients with Cushing's syndrome was not different from the non-diabetic controls, whereas GA was significantly lower. In 7 patients with Cushing's syndrome who performed self-monitoring of blood glucose, the measured HbA1c was matched with HbA1c estimated from mean blood glucose, whereas the measured GA was significantly lower than the estimated GA. We clarified that GA is set lower in relation to plasma glucose levels in patients with Cushing's syndrome. Copyright © 2013 Elsevier B.V. All rights reserved.

  7. The Effects of Reduction Mammaplasty on Serum Leptin Levels and Insulin Resistance

    Hakan Uzun

    2015-01-01

    Full Text Available Background. The reduction mammaplasty has been a well-executed and known procedure in which considerable amount of fatty tissue is removed from the body. The authors aimed to show the effects of the reduction mammaplasty on serum leptin levels and insulin resistance. Methods. 42 obese female patients who had gigantomastia were operated on. We recorded patients’ demographic and preoperative data, including age, weight, height, and body mass index. Fasting serum leptin, glucose, and insulin levels were noted. Homeostasis model assessment scores were calculated. At the postoperative 8th week, patients were reevaluated in terms of above parameters assessing the presence of any difference. Results. Serum leptin levels were decreased postoperatively and the decrease was statistically significant. We were able to show a decrease in homeostasis model assessment score, which indicated an increase in insulin sensitivity, and this change was statistically significant. A significant correlation between body mass index and leptin change was found postoperatively. Conclusion. Reduction mammaplasty is not solely an aesthetic procedure but it decreases serum leptin levels and increases insulin sensitivity, which may help obese women to reduce their cardiovascular risk.

  8. Influence of dexamethasone and weight loss on the regulation of serum leptin levels in obese individuals

    D.D.G. Lerario

    2001-04-01

    Full Text Available The adipocyte hormone leptin is thought to serve as a signal to the central nervous system reflecting the status of fat stores. Serum leptin levels and adipocyte leptin messenger RNA levels are clearly increased in obesity. Nevertheless, the factors regulating leptin production are not fully understood. The aim of this study was to determine the effects of in vivo administration of the synthetic glucocorticoid dexamethasone and weight loss on serum leptin levels in two independent protocols. Twenty-five obese subjects were studied (18 women and 7 men, mean age 26.6 ± 6 years, BMI 31.1 ± 2.5 kg/m², %fat 40.3 ± 8.3 and compared at baseline to 22 healthy individuals. Serum levels of leptin, insulin, proinsulin and glucose were assessed at baseline and after ingestion of dexamethasone, 4 mg per day (2 mg, twice daily for two consecutive days. To study the effects of weight loss on serum leptin, 17 of the obese subjects were submitted to a low-calorie dietary intervention trial for 8 weeks and again blood samples were collected. Serum leptin levels were significantly higher in the obese group compared to the control group and a high positive correlation between leptinemia and the magnitude of fat mass was found (r = 0.88, P<0.0001. After dexamethasone, there was a significant increase in serum leptin levels (22.9 ± 12.3 vs 51.4 ± 23.3 ng/ml, P<0.05. Weight loss (86.1 ± 15.1 vs 80.6 ± 14.2 kg, P<0.05 led to a reduction in leptin levels (25.13 ± 12.8 vs 15.9 ± 9.1 ng/ml, P<0.05. We conclude that serum leptin levels are primordially dependent on fat mass magnitude. Glucocorticoids at supraphysiologic levels are potent secretagogues of leptin in obese subjects and a mild fat mass reduction leads to a disproportionate decrease in serum leptin levels. This suggests that, in addition to the changes in fat mass, complex nutritional and hormonal interactions may also play an important role in the regulation of leptin levels.

  9. Serum homocyst(e)ine levels in women with preeclampsia.

    Endothelial dysfunction has been described as the final common pathophysiological pathway in the development of preeclampsia. Since it has been suggested that homocyst(e)ine damages endothelial cells, we measured serum homocyst(e)ine levels in women with preeclampsia and in healthy pregnant women in order to find a new prognostic parameter for women with preeclampsia. Forty-five women with preeclampsia and 45 healthy women with uncomplicated pregnancies, matched for age and parity, were entered into the study. Serum homocyst(e)ine levels were measured by gas chromatography-mass spectrometry analysis and correlated to clinical data. Logistic regression models were used to analyse the influence of serum homocyst(e)ine levels on the presence of preeclampsia versus healthy pregnant women and on the risk of premature termination of pregnancy due to preeclampsia. Median serum homocyst(e)ine levels in women with preeclampsia and healthy pregnant women were 14.2 (range 5.7-38.1) mumol/L and 15.1 (range 5.2-23.1) mumol/L, respectively (Mann-Whitney U-test, p = 0.8). In univariate logistic regression models, serum homocyst(e)ine levels had no significant influence on the odds of presenting with preeclampsia versus healthy pregnant women (univariate logistic regression model, p = 0.8) and on the odds of premature termination of pregnancy due to preeclampsia (univariate logistic regression model, p = 0.3). Serum homocyst(e)ine levels are not elevated in women with preeclampsia and are not associated with clinical outcome in women with preeclampsia.

  10. Effects of a fibre-enriched milk drink on insulin and glucose levels in healthy subjects

    Pilvi Taru K

    2009-10-01

    Full Text Available Abstract Background The glycaemic response to foods is dependent on the quality and content of carbohydrates. Carbohydrates in the form of dietary fibre have favourable effects on insulin and glucose metabolism and may help to control energy intake. Dairy products have a relatively low carbohydrate content, and most of the carbohydrate is in the form of lactose which causes gastrointestinal symptoms in part of the population. In order to avoid these symptoms, dairy products can be replaced with lactose-free dairy products which are on the market in many parts of the world. However, the effects of lactose-free products on insulin and glucose metabolism have not been studied. Methods In the present study, we investigated the effects of 1 a lactose-free milk drink, 2 a novel fibre-enriched, fat- and lactose-free milk drink and 3 normal fat-free milk on serum glucose and insulin levels and satiety using a randomized block design. Following an overnight fast, 26 healthy volunteers ingested 200 ml of one of these drinks on three non-consecutive days. Insulin and glucose levels and subjective satiety ratings were measured before the ingestion of the milk product and 20, 40, 60, 120 and 180 minutes after ingestion. The responses were calculated as the area under the curve subtracted by the baseline value (AUC minus baseline. Results The insulin response was significantly lower for the fibre-enriched milk drink than it was for the other milk products (AUC, P = 0.007. There were no differences in the response for glucose or in the AUC for the subjective satiety ratings between the studied milk products. Conclusion The present results suggest that this novel milk drink could have positive effects on insulin response.

    Vemula, Praveen; Abela, Oliver G; Narisetty, Keerthy; Rhine, David; Abela, George S

    2015-01-01

    Refeeding syndrome is a life-threatening condition occurring in severely malnourished patients after initiating feeding. Severe hypophosphatemia with reduced adenosine triphosphate production has been implicated, but little data are available regarding electrolyte abnormalities. In this case, we report electrocardiographic changes consistent with hyperkalemia during potassium replacement after a serum level increase from 1.9 to 2.9 mEq/L. This was reversed by lowering serum potassium back to 2.0 mEq/L. In conclusion, the patient with prolonged malnutrition became adapted to low potassium levels and developed potassium toxicity with replacement. Copyright © 2015 Elsevier Inc. All rights reserved.

  12. Serum thiamine level during the initiation term of hemodialysis

    2012-06-01

    Although water-soluble vitamins such as thiamine are lost during dialysis session, serum thiamine level tended to restore spontaneously during the hospitalization (25.47±10.07 vs. 27.44±11.37, pre HD value, p=0.09. A three months-follow up measurement after initiation of HD, which is now in progress (so far n=3, revealed increase of serum thiamine level in all patients (35.33±7.37 ng/ml. It may reflect the improvement of nutritional status after the initiation of HD, and suggests the loss of thiamine by HD procedure can be covered.

    2018-04-01

    Recent studies have shown that atherosclerosis is associated with erectile dysfunction and the serum bilirubin level. In this study, the serum total bilirubin levels of patients with erectile dysfunction were measured to investigate the relationship between the levels of erectile dysfunction and total bilirubin. A total of 94 patients with erectile dysfunction were divided into three groups; severe erectile dysfunction (33 patients), moderate erectile dysfunction (31 patients), and mild erectile dysfunction (30 patients). In addition, a control group was formed with 31 healthy men. The International Index of Erectile Function-5 Questionnaire was used to measure the quality of erection in all the groups. The body mass index was calculated for all the participants. The serum glucose, low-density lipoprotein and high-density lipoprotein, cholesterol, triglyceride, total bilirubin, and total testosterone levels were also determined. No statistically significant difference was observed between the groups in terms of the mean age, hypertension, smoking status, alcohol use, cardiovascular diseases, hepatobiliary disease, diabetes mellitus, and levels of total testosterone, low-density lipoprotein-cholesterol, and triglyceride. However, high-density lipoprotein, body mass index, and total bilirubin were significantly lower compared to the control group (p < 0.001). The serum total bilirubin level was found to be 0.41 ± 0.21 ng/dL in the severe erectile dysfunction, 0.43 ± 0.19 ng/dL in the moderate erectile dysfunction, and 0.48 ± 0.11 ng/dL in the mild erectile dysfunction groups (p < 0.001). Considering the significant differences between the erectile dysfunction and control groups in terms of serum total bilirubin levels, a low level of bilirubin may have a role in the etiology of erectile dysfunction.

    Inflammatory cytokines such as interleukin-6 (IL-6) and tumor necrosis factor-alpha (TNF-alpha) may have a direct effect on glucose and lipid metabolism. On the other hand, it is known that IL-6 and TNF-alpha are important pro-inflammatory cytokines in the pathogenesis of atherosclerosis. The goal of present study was to test whether sleep apnea contributes to the previously reported increases of IL-6 and TNF-alpha independent of obesity. Forty-three obese (body mass index, BMI>27 kg/m2) men with newly diagnosed obstructive sleep apnea syndrome (OSAS) (apnea-hypopnea index, AHI> or =5) and age- and BMI-matched 22 obese nonapneic male controls (AHI<5) were enrolled in this study. To confirm the diagnosis, all patients underwent standard polysomnography in the sleep disorders center. Serum samples were taken at 08:00 h in the morning after overnight fasting. Serum IL-6 and TNF-alpha levels were found significantly higher in OSAS patients than in controls (p=0.002, p=0.03). Serum IL-6 and TNF-alpha levels were significantly correlated with AHI in OSAS patients (r=0.03, p=0.046 and r=0.36, p=0.016). There was no significant correlation between serum IL-6, TNF-alpha levels and AHI in controls. Serum IL-6 and TNF-alpha levels were not correlated with BMI both in OSAS patients and controls. In conclusion, circulating IL-6 and TNF-alpha levels in patients with OSAS, as independent of BMI are significantly higher than levels in controls and there is a positive relationship between previously mentioned cytokines' levels and the severity of OSAS. According to these results, the link between cardiovascular morbidity and OSAS may be explained by the coexistence of other cardiovascular risk factors such as circulating IL-6 and TNF-alpha levels.

    Objective: To investigate a correlation between serum alkaline phosphatase level and body mass index in human subjects. Methods: The comparative cross-sectional study was carried out at the National Institute for Biotechnology and Genetic Engineering, Faisalabad, Pakistan, from April 2012 to June 2013. Blood serum alkaline phosphatase levels were estimated and the subjects were divided into three sub-groups on the basis of their body mass index: normal weight (<25kg/m2), overweight (25-27kg/m2) and obese (>27kg/m2) subjects. The serum samples were used for the estimation of clinically important biochemical parameters, using commercial kits on clinical chemistry analyser. Results: Of the 197 subjects, 97(49 percent) were obese and 100(51 percent) were non-obese. The serum alkaline phosphatase level increased in obese (214±6.4 IU/L) compared to the non-obese subjects (184.5±5 IU/L). Furthermore, a significant linear relationship (r=0.3;p-0.0001) was found between serum alkaline phosphatase and body mass index. Other biochemical variables were not correlated to the body mass index. Conclusion: Over activity and higher amounts of alkaline phosphatase were linked to the development of obesity. (author)

  16. Elevated Adiponectin Serum Levels in Women with Systemic Autoimmune Diseases

    Éric Toussirot

    2010-01-01

    Full Text Available Adipose tissue produces a wide range of proteins that may influence the immune system. In this study, we assessed the serum levels of leptin, adiponectin, and ghrelin, in association with the measurements of body composition, in 15 female patients with various autoimmune diseases (systemic lupus erythematosus, primary Sjögren's syndrome, sarcoidosis, mixed connective tissue disease, vasculitis, CREST syndrome, and polymyositis and in 15 healthy female controls. There were no statistically significant differences between the patients and controls with regard to serum leptin, serum ghrelin, global fat mass, adiposity, and fat mass in the android or gynoid regions, whereas serum adiponectin levels were higher in patients than controls (16.3±1.6 μg/mL versus 9.7±0.6 μg/mL; =.01. As adiponectin is known to exhibit potent anti-inflammatory properties, a high adiponectinemia in patients with systemic autoimmune disease may mitigate the inflammatory response. However, the precise consequences of these elevated serum adiponectin levels on the metabolic syndrome development and atherosclerotic cardiovascular risk in this patient population still needs to be determined.

    2009-02-01

    Serum carnitine is decreased in recurrent pulmonary infections. We aimed to evaluate serum carnitine levels in asthmatic children. Study group consisted of children with stable asthma and those with acute asthma attacks, while control group included healthy children. Attack severity was determined by the pulmonary score system. Total and free carnitine levels were studied in one blood sample from the control group and stable asthmatics and in two samples from children with acute asthma exacerbation during and after the attack. All the 40 patients in the study group had moderate asthma including 30 with acute attack (13 mild and 17 moderate) and 10 with stable asthma. Carnitine levels were significantly lower in acute attack asthmatics than in the stable asthmatics and controls, while there was no significant difference between the latter two groups. Carnitine levels were not different between asthmatics with mild and moderate attack, and were similar during and after an acute attack. Serum carnitine levels decrease in children with moderate asthma during exacerbation of asthma and shortly thereafter. Further studies are needed to evaluate the effect of carnitine treatment on serum carnitine level.

    2013-01-01

    Full Text Available Background. Few studies have shown that self-reported secondhand smoke exposure in never smokers is associated with high blood pressure. However, there are no studies investigating the relationship between secondhand smoke exposure, measured objectively by serum cotinine levels, and high blood pressure in never smokers. Methods. We examined never smokers (n=2027 from the National Health and Nutrition Examination Survey 2005–2008. Our exposure of interest was the secondhand smoke exposure estimated by serum cotinine level and our outcome was prehypertension (n=734, defined as a systolic blood pressure of 120–139 mmHg or diastolic blood pressure of 80–89 mmHg. Results. We found that, in never smokers, serum cotinine levels were positively associated with prehypertension. Compared to those with cotinine levels in the lowest quartile (≤0.024 ng/mL, the multivariable odds ratio (95% confidence interval of prehypertension among those with cotinine levels in the highest quartile (≥0.224 ng/mL was 1.45(1.00, 2.11; P trend =0.0451. In subsequent subgroup analyses, the positive association was found to be stronger among men, non-Whites, and non-obese subjects. Conclusion. Higher secondhand smoke exposure measured objectively by serum cotinine levels was found to be associated with prehypertension in certain subgroups of a representative sample of the US population.

    2001-11-01

    To assess the comparative efficacy of IVF medium (MediCult, with 5.2 mM glucose) and a glucose/phosphate-free medium, P1 (Irvine Scientific), and to investigate the influence of increasing the serum supplementation (synthetic serum substitute; SSS; Irvine Scientific) to P1 on embryo development and implantation. Patients were randomly assigned to IVF medium (Group 1, cycles n = 172) or P1 supplemented with 10% SSS (Group 2, cycles n = 229) according to the medium scheduled for use on the day of oocyte retrieval. Another 555 IVF consequent cycles (Group 3) were performed using increased SSS concentrations (20%) in P1 medium. In this large series of IVF cycles, we herein demonstrate that significantly higher pregnancy and implantation rates were found when embryos were cultured in glucose/phosphate-free medium P1 supplemented with 20% SSS compared to supplementation with the lower SSS concentration and with IVF medium.

    2003-01-01

    To explore the relationship between serum total homocysteine (Hcy) level and II diabetes mellitus (DM) with hyperinsulinism and insulin resistance, serum total Hcy level in 30 normal subjects and 78 type II DM (38 with hyperinsulinism) are detected. The results show: the mean serum Hcy level is 11.90 ± 3.90 μmo/L, 9.21 ± 2.83 μmol/L at oral glucose tolerance test (OGTT) 1 h and 10.43 ± 3.82 μmol/L at OGTT 2h in normal subjects (n=30); 21.80 ± 7.98 μmol/L, 17.98 ± 6.83 μmol/L at OGTT 1 h and 12.58 ± 6.73 μmol/L at OGTT 2 h in DM without hyperinsulinism and angiopathy (n=40); and 19.80 ± 7.98 μmol/L, 14.50 ± 7.69 μmol/L at OGTT 1 h and 11.07 ± 6.52 μmol/L at OGTT 2 h in DM with hyperinsulinism (n=38). The Hcy level is a significant difference among three groups (P<0.001, P<0.01). Hcy level of DM with hyperinsulinism is lower than that of DM with hyperinsulinism (P<0.01). The serum Hcy level in DM is higher than that in control group, the elevated level of serum Hcy may be related to the diabetic hyperinsulinism and insulin resistance

    2006-01-01

    Objective: To study the clinical meanings of changes of serum C-peptide levels and insulin/C-peptide ratio. Methods: Serum insulin and C-peptide levels were determined with RIA in 171 patients with DM-2 of all ages (31-50, n= 50, 51-60, n=60, over 60, n=61) and 50 patients with renal insufficiency. The insulin/C-peptide ratio were calculated. Results: The serum C-peptide and insulin levels in patients with renal insufficiency were significantly higher than those in diabetics of all age groups and the insulin/C-peptide ratio were significantly lower than those in diabetics (P 0.05), but the serum C-peptide levels increased as the age of patients increased with decrease of insulin/C-peptide ratio (P<0.01). Conclusion: Abnormal changes of C-peptide levels and insulin/C-peptide ratio in diabetics (the age-factor corrected) might reflect renal dysfunction. (authors)

    2012-01-01

    The current worldwide increases of type 2 diabetes mellitus (T2DM) in children coincide with increases in the prevalence of obesity. We investigated the insulin resistance and adiponectin levels of children and adolescents with a family history of T2DM (FHD). Our sample included 131 children and adolescents aged 8-15 years. Fasting plasma glucose, lipids, fasting insulin, adiponectin levels and HOMA-IR were analyzed according to FHD and obesity. Oral glucose tolerance tests were performed in all subjects except non-obese subjects without FHD. Adiponectin levels of subjects with FHD were significantly lower than those of subjects without FHD in both the obese and nonobese groups. HOMA-IR was significantly higher in obese subjects with FHD than in those without FHD. Adiponectin levels were found to be independently associated with FHD and Matsuda index. The frequency of impaired glucose tolerance in obese subjects with FHD was more than four times higher compared to obese subjects without FHD.

    The causes of late-onset Alzheimer disease (AD) are not yet understood but likely include a combination of genetic, environmental, and lifestyle factors. Limited epidemiological studies suggest that occupational pesticide exposures are associated with AD. Previously, we reported that serum levels of dichlorodiphenyldichloroethylene (DDE), the metabolite of the pesticide dichlorodiphenyltrichloroethane (DDT), were elevated in a small number of patients with AD (n=20). To evaluate the association between serum levels of DDE and AD and whether the apolipoprotein E (APOE) genotype modifies the association. A case-control study consisting of existing samples from patients with AD and control participants from the Emory University Alzheimer's Disease Research Center and the University of Texas Southwestern Medical School's Alzheimer's Disease Center. Serum levels of DDE were measured in 79 control and 86 AD cases. Serum DDE levels, AD diagnosis, severity of AD measured by the Mini-Mental State Examination score, and interaction with APOE4 status. Levels of DDE were 3.8-fold higher in the serum of those with AD (mean [SEM], 2.64 [0.35] ng/mg cholesterol) when compared with control participants (mean [SEM], 0.69 [0.1] ng/mg cholesterol; P risk for AD (95% CI, 2.54-5.82; P risk for AD and carriers of an APOE4 ε4 allele may be more susceptible to the effects of DDE. Both DDT and DDE increase amyloid precursor protein levels, providing mechanistic plausibility for the association of DDE exposure with AD. Identifying people who have elevated levels of DDE and carry an APOE ε4 allele may lead to early identification of some cases of AD.

    1972-01-01

    Serum immunoglobulins (SI) were determined in 803 survivors and matched controls. Each subject's age, sex, health, exposure, and medical record were evaluated with respect to serum IgG, IgA, IgM levels. The IgG and IgA levels tended to be higher for this Hiroshima population than for Americans. Past exposure to ionizing radiation showed no significant correlation to SI levels. However, age and sex did influence the SI. IgM was significantly higher in females. With advancing age IgG and IgA increased in males, and IgM decreased in females. Elevated sedimentation rate and increased lymphocytes were accompanied by increased SI levels. Radiographic TB was detected in 45% of the population; IgG and IgA levels were somewhat elevated in these individuals. (DLC)

    Full Text Available Aim To compare plasma IL-10 concentrations in patients with Acute Coronary Syndrome (ACS with those in Coronary Artery Disease (CAD.Methods ACS patients hospitalized in intensive coronary care unit (ICCU of Cipto Mangunkusumo Hospital/Faculty of Medicine University of Indonesia (CMH/FMUI, Persahabatan Hospital, MMC Hospital, and Medistra Hospital, Jakarta, between May 2005 and May 2006, were included in this study. The ambulatory CAD patients were taken as comparator. The serum IL-10 level was measured by immunoassay method, and compared by using Independent Student’s t-test. To investigate whether IL-10 serum level could predict ACS, the sensitivity and specificity of this parameter towards ACS in various IL-10 serum levels were calculated as well.Results In this observational study, as many as 146 subjects were analyzed, consisting of 84 ACS patients, and 62 coronary artery disease (CAD. The IL-10 level was higher in the group of ACS patients (7.37 pg/mL + 7.81, CI 95% 5.68-9.07 than that in CAD patients (1.59 pg/mL + 1.55, CI 95% 1.2-1.98. The optimal cut-off point for serum IL-10level is >1.95 pg/mL, with 79.76 % sensitivity and 77.42 % specificity.Conclusion The IL-10 level was higher in the ACS patients compared to that in CAD patients. Serum IL-10 measurement is a quite superior method to distinguish acute and stable condition, eventhough it is not as good as hsCRP for the same purpose.

    1984-01-01

    The diagnosis of borderline hyperthyroidism is difficult. A sensitive radioimmunoassay capable of detecting subnormal levels of serum TSH may be of value in confirming this diagnosis because of the suppressed pituitary function in this disease state. This sensitive assay may also be useful in monitoring the suppression of pituitary function in thyroid cancer patients receiving thyroid hormone therapy. A sensitive radioimmunoassay capable of detecting serum TSH levels as low as 0.25 μU/m1 with coefficients of variation less than 17.2% was used to measure serum TSH levels in 80 healthy subjects, 44 hyperthyroid patients, and 25 athyrotic thyroid cancer patients on daily suppressive doses of thyroxine. All healthy subjects had detectable TSH levels with a mean value of 1.17 and two standard deviation ranges of 0.41 - 2.70 μU/m1 (lognormal distribution). Although the mean +-1 SEM value of 0.63 +- 0.003 μUm1 for hyperthyroid patients and 0.76 +- 0.08 μU/ml for thyroid cancer patients were significantly lower than that of healthy subjects (t-test, p<0.05), subnormal levels of serum TSH were found in only 28.6% (12/42) and 24% (6/25) of hyperthyroid and thyroid cancer patients, respectively. TSH stimulation tests performed in 6 of the cancer patients all gave suppressed responses. Because of considerable overlap, serum TSH levels alone cannot distinguish hyperthyroidsm from euthyroidism. However, a sensitive TSH radioimmunoassay such as the one described here may be of value in evaluating the extent of pituitary suppression in thyroid cancer therapy

    Full Text Available Background/Aims: Hyperuricemia has been reported to affect renal hemodynamics in rat models. We evaluate the relationship between serum uric acid and intrarenal hemodynamic parameters in humans, utilizing the plasma clearance of para-aminohippurate (CPAH and inulin (Cin. Methods: Renal and glomerular hemodynamics were assessed by simultaneous measurement of CPAH and Cin in 58 subjects. Of these, 19 subjects were planned to provide a kidney for transplantation; 26 had diabetes without proteinuria; and 13 had mild proteinuria. Renal and glomerular hemodynamics were calculated using Gomez`s formulae. Results: Cin was more than 60 ml/min/1.73m2 in all subjects. Serum uric acid levels correlated significantly with vascular resistance at the afferent arteriole (Ra (r = 0.354, p = 0.006 but not with that of the efferent arteriole (Re. Serum uric acid levels (β = 0.581, p = a after adjustment for several confounders (R2 = 0.518, p = Conclusions: These findings suggest, for the first time in humans, that higher serum uric acid levels are associated significantly with Ra in subjects with Cin > 60 ml/min/1.73m2. The increase in Ra in subjects with higher uric acid levels may be related to dysfunction of glomerular perfusion.

    Malekahmadi, Mohammad; Farrahi, Fereydoun; Tajdini, Afshin

    2017-01-01

    Chalazion is a chronic, localized lipogranulomatous inflammation of the sebaceous glands of the lids. Chalazion occurs often secondary to blockage of the sebaceous gland ducts. Some studies have reported vitamin A deficiency as a risk factor for chalazion. In this study, we determined the serum levels of vitamin A in patients with chalazion. The study involved a total of 107 subjects (52 patients with chalazion and 55 control healthy subjects). The study was conducted at the Ophthalmology Clinics of Imam Khomeini Hospital, Ahwaz Jundishapur University of Medical Sciences, Ahwaz, Iran between September 2014 and February 2015. The subjects were divided into three groups according to age: 7-12 years old, 13-19 years old, and more than 19 years old. Patients were further divided into four subgroups based on the type of chalazion: single, multiple, primary, and recurrent. Blood samples were collected and the serum was tested for levels of vitamin A using high-performance liquid chromatography (HPLC). The average serum vitamin A levels in patients with chalazion in the age groups of 7-12 and 13-19 years were significantly lower than in their control counterparts. Serum vitamin A levels in patients with recurrent, multiple chalazia were significantly lower than in patients with primary, multiple chalazia (P = 0.026) and patients with a recurrent, single chalazion (P = 0.029). In conclusion, chalazion could be one of the ocular presentations of vitamin A deficiency.

    2016-02-01

    Our aim was to assess serum levels of the soluble receptor for advanced glycation end products (sRAGE) and to examine their association with anthropometric and metabolic parameters in patients with prediabetes and obese controls. The two study groups were composed of 42 patients with prediabetes and diabetic neuropathy and 42 age-, gender-, body weight (BW)-, and body mass index (BMI)-matched obese adults as the control group. Prediabetes was diagnosed by the following criteria issued by the American Diabetes Association: impaired fasting glucose [fasting plasma glucose (FPG) level of 100-125 mg/dL], impaired glucose tolerance (2 hr plasma glucose level of 140-199 mg/dL after a 75 grams oral glucose challenge), or a glycated hemoglobin (HbA1C) level of 5.7%-6.4%. There were no differences between the groups in terms of age, gender distribution, BW, or BMI. Despite these similarities, patients with prediabetes had higher FPG, HbA1c, and 2-hr postchallenge glucose levels, higher systolic and diastolic blood pressure, and larger waist and hip circumferences compared with the obese controls. Lipid measurements, complete blood counts, kidney and liver function tests, high-sensitivity C-reactive protein, and sRAGE levels were similar between the two groups. We found significant negative correlations between sRAGE levels and BW, BMI, waist and hip circumferences, waist-to-hip ratios, and low-density lipoprotein (LDL) cholesterol levels. There were no significant correlations with other parameters, including demographic, metabolic, and blood pressure measurements. In contrast to glycemic parameters, serum levels of sRAGE were negatively correlated with body measurements indicative of obesity in the prediabetic state. In addition, the negative correlation with LDL cholesterol levels suggests that sRAGE has a more robust association with metabolic syndrome than with prediabetes.

  3. Zero net flux estimates of septal extracellular glucose levels and the effects of glucose on septal extracellular GABA levels

    Krebs-Kraft, Desiree L.; Rauw, Gail; Baker, Glen B.; Parent, Marise B.

    2009-01-01

    Although hippocampal infusions of glucose enhance memory, we have found repeatedly that septal glucose infusions impair memory when γ-aminobutyric acid (GABA) receptors are activated. For instance, hippocampal glucose infusions reverse the memory-impairing effects of co-infusions of the GABA agonist muscimol, whereas septal glucose infusions exacerbate memory deficits produced by muscimol. One potential explanation for these deleterious effects of glucose in the septum is that there are highe...

    1997-01-01

    Aluminium is produced from the mineral bauxite. Occupational exposure is reported during the industrial processing of aluminium and is associated with pulmonary and neurotoxicity. However, data on exposure and toxicity of workers in the open bauxite mining industry do not exist. Therefore, a study was performed to explore aluminium exposure in employees involved in this bauxite mining process in a Surinam mine. A group of workers occupationally exposed to aluminium in an open bauxite mine were compared with a group of nonexposed wood processors. Serum aluminium was analyzed using atomic absorption spectrometry Data from the clinical chemistry of the blood and a questionnaire were used to explore determinants for aluminium exposure. No significant difference between serum aluminium in the exposed (4.4 +/- 2.0 micrograms/L, n = 27) and control group (5.1 +/- 1.5 micrograms/L, n = 27) was detected. For the serum concentration of the clinical chemical variables (calcium, citrate, and creatinine), a statistically significant difference was computed (p < or = 0.02) between the exposed and control group. All levels were slightly higher in the exposed group; no statistically significant correlations with serum aluminium were found. In this study, serum aluminium values were in the normal range, no significant difference between the groups could be detected despite long-term occupational exposure.

    To study the changes in concentrations of serum hyaluronic acid in uncomplicated human pregnancies. We determined the concentrations of serum hyaluronic acid, using a specific enzyme-linked immunosorbent assay, in 70 nonpregnant women, 250 women during their pregnancies, and 68 women at the time of parturition. Results were analyzed for statistical significance with Scheffé test for multiple comparisons. During pregnancy, mean (+/- standard deviation) serum hyaluronic acid levels were 11.4 +/- 4.5, 13.6 +/- 2.8, 20.6 +/- 1.5, and 46.9 +/- 7.9 ng/mL at 5-14 (n = 47), 15-26 (n = 46), 27-37 (n = 58), and 38-40 (n = 99) weeks' gestation, respectively. Pregnant women in labor (n = 68) had significantly higher levels (100.4 +/- 11.3 ng/mL) than did women at term but not in labor (P hyaluronic acid concentrations increase as pregnancy progresses and serum levels increase significantly at term. Hyaluronic acid may be associated with cervical ripening during parturition.

    2014-01-01

    Full Text Available Background: Excess serum uric acid (UA accumulation can lead to various diseases. Increasing evidences reveal that UA may have a key role in the pathogenesis of metabolic syndrome. Little is known about the associations of UA levels with cardiometabolic risk factors in prediabetic individuals. This study was designed to evaluate the association between UA and cardiometabolic risk factors in prediabetic subjects with family history of diabetes compared with those with normal glucose tolerance (NGT. Materials and Methods: In a cross-sectional setting, a sample containing 643 (302 prediabetic subjects and 341 normal of the first-degree relatives of diabetic patients aged 35-55-years old were investigated. Samples were assessed in prediabetic and normal groups using glucose tolerance categories. Prediabetes was defined based on American Diabetes Association (ADA criteria. Body weight and height, systolic and diastolic blood pressure (SBP and DBP, UA, creatinine (Cr, albumin (Alb, fasting blood glucose (FBG, hemoglobin A1c (HbA1c, and lipid profiles were measured and compared between two groups. Results: Prediabetic persons were older and obese than normal persons. Also, prediabetic persons (5.2 ± 1.3 mg/dl had significantly higher UA than normal persons (4.9 ± 1.4 mg/dl (P 1, P < 0.05 associated with glucose tolerance categories. This association remained statistically significant after adjusting the effects of age and BMI. Also, the association between glucose tolerance categories and UA were positively significant in both genders. Conclusion: High UA level was associated with some cardiometabolic risk factors in prediabetic individuals compared with normal person. UA level was also a significant predictor for prediabetes condition.

    In addition to tumors, normal tissues, such as the brain and myocardium can intake {sup 18}F-FDG, and the amount of {sup 18}F-FDG intake by normal tissues can be altered by the surrounding environment. Therefore, a process is necessary during which the contrasts of the tumor and normal tissues can be enhanced. Thus, this study examines the effects of glucose levels on FDG PET images of brain tissues, which features high glucose activity at all times, in small animals. Micro PET scan was performed on fourteen mice after injecting {sup 18}F-FDG. The images were compared in relation to fasting. The findings showed that the mean SUV value w as 0 .84 higher in fasted mice than in non-fasted mice. During observation, the images from non-fasted mice showed high accumulation in organs other than the brain with increased surrounding noise. In addition, compared to the non-fasted mice, the fasted mice showed higher early intake and curve increase. The findings of this study suggest that fasting is important in assessing brain functions in brain PET using {sup 18}F-FDG. Additional studies to investigate whether caffeine levels and other preprocessing items have an impact on the acquired images would contribute to reducing radiation exposure in patients.

    Full Text Available Objective: To determine the role of hepcidin hormone levels in iron accumulation in patients with thalassemia major (TM and thalassemia intermedia (TI. Materials and Methods: Serum prohepcidin and ferritin levels were determined in 34 patient with TM, 10 patient with TI, who attended the Department of Pediatric Hematology Adnan Menderes University Medical Faculty and the Department of Pediatrics at Aydın Atatürk State Hospital between 1 September 2006 and 30 September 2007 and 40 control patients without infection/inflammation, hepatitis or liver failure. Serum prohepcidin levels were measured using a commercial enzyme-linked immunosorbent assay kit (DRG International, Inc. Marburg, Germany; ferritin was studied with chemiluminescence method (Immulite 2000 DPC. Results: Mean serum ferritin levels in TM, TI and control groups were 2347.97±1724.81 ng/mL (range: 144-8015 ng/mL, 1352.40±918.94 ng/mL (range: 311-3109 ng/mL, and 33.35±12.03 ng/mL (range: 20-69.1 ng/mL, respectively. Serum prohepcidin levels in the same groups were 221.78±74.38 ng/mL (range: 7l.14-446.57 ng/mL, 173.31±52.14 ng/mL (range: 100.83-267.69 ng/mL, and 218.20±50.37 ng/mL (range: 116.18-330.43 ng/mL, respectively. There was a statistically significant difference in prohepcidin levels between patients with TI and control group only (p=0.016. No correlation was found between prohepcidin and ferritin levels in all groups (r=-0.023, p=0.839. Conclusion: Low levels of prohepcidin in patients with TI may be related to increased erythropoietic activity. Prohepcidin can be an indicator of active erythropoiesis.

    The primary aim of the research was to assess the level of trace elements and electrolytes in serum of postmenopausal diabetic women. Sixty-four postmenopausal women with type 2 diabetes mellitus (DM2) and 64 age- and body mass index-matched controls were examined. Serum trace elements were assessed using inductively coupled plasma dynamic reaction cell mass spectrometry (ICP-DRC-MS). Fasting plasma glucose (FPG) and glycated hemoglobin (HbA 1c ) levels were evaluated using Randox kits. The obtained data demonstrate that DM2 patients were characterized by 42 and 34 % higher FPG and HbA 1c levels, respectively (p women was increased by 10 and 15 % in comparison to the respective control values (p = 0.002 and DM2 pathogenesis. Further studies are required to assess the intimate mechanisms of the observed differences.

  11. Radioimmunoassay of serum digoxin levels in digitalis intoxication

    Arendt, G.

    1981-01-01

    For 101 hospitalized patients where clinical symptoms of a glucosidine intoxication as a consequence of oral digoxin treatment were noted, serum digoxin levels were determined using a RIA kit of the Boehringer company (I-125 tracer, solid phase tube separation technique) on a fasted stomach prior to oral drug administration. An ECG was performed simultaneously and in addition kidney function parameters and electrolyte levels were determined. An anamnesis and clinical examination of the patients were also conducted. Interferences in the RIA method and gastro-intestinal illness resulting in changes in resorption behaviour were excluded. The group of patients showed collectively an average serum digoxin level of 2.9 +- 0.9 ng/ml with a range from 1.8 to 6.8 ng/ml, which was statistically significantly higher than the average value for 101 patients receiving long-term oral medication but without symptoms of glycosidine intoxication. According to the manufacture's specifications for the RIA kit, values > 2.0 ng/ml are considered as toxic, with values between 1.6 and 2.0 ng/mg falling into a ''grey zone''. A correlation was found between toxic serum values with changes in ECG pattern and subjective clinical symptoms of intoxication. A limitation of kidney function was responsible for the high serum glycoside levels in 62% of the patients. It was shown that the differing response of patients towards digitalis medication, above all in the case of long-term therapy, warrants an RIA determination of serum glycoside values in order to adjust the digoxin dose to individual requirements.

  12. CORRELATION OF GALLSTONE FORMATION WITH SERUM IRON LEVELS

    Rohini Bipin Bhadre

    2016-07-01

    Full Text Available INTRODUCTION Gallstones are one of the most common problem associated with the gallbladder, affecting millions of people throughout the world. Bile is excreted from liver and gallbladder into Duodenum for digestion. After digestion, if the gallbladder is not emptied out completely, the Bile Juice that remains in the gallbladder can become too concentrated with cholesterol leading to gallstone formation. Cholesterol and calcium bilirubinate are the two main substances involved in gallstone formation. Gallstones derived from bile consists of mixture of cholesterol, bilirubin with or without calcium. Based on their chemical composition, gallstones found in the gallbladder are classified as cholesterol, pigmented or mixed stones. Iron deficiency has been shown to alter the activity of several hepatic enzymes, leading to increased gallbladder bile cholesterol saturation and promotion of cholesterol crystal formation. AIMS & OBJECTIVE Attempt to establish a correlation with gallstones and decreased serum iron levels. MATERIAL & METHODS This study was a prospective cohort study which included 100 consecutive patients with imaging studies suggestive of Cholelithiasis. The Gallstone surgically removed was crushed with mortar and pestle and then analysed for cholesterol, calcium, phosphate and bilirubin (pigment. Serum samples were analysed for Cholesterol, iron and iron binding capacity. RESULTS 86% patients had increased cholesterol levels (p=0.04 and 93% had decreased serum Iron levels (p=0.96. The most common type of gallstone was found to be Cholesterol type of gallstone followed by Mixed and Pigment gallstones. CONCLUSION Serum cholesterol levels were found to be raised in majority of the patients and serum iron was found to be low in these majority of the patients indicating iron deficiency may play a role in gallstone formation.

    We evaluated serum total bilirubin levels as a predictor for metabolic syndrome (MetS) and investigated the relationship between serum total bilirubin levels and MetS prevalence. This cross-sectional study included 1728 participants over 65 years of age from Eastern China. Anthropometric data, lifestyle information, and previous medical history were collected. We then measured serum levels of fasting blood-glucose, total cholesterol, triglycerides, and total bilirubin, as well as alanine aminotransferase activity. The prevalence of MetS and each of its individual component were calculated per quartile of total bilirubin level. Logistic regression was used to assess the correlation between serum total bilirubin levels and MetS. Total bilirubin level in the women who did not have MetS was significantly higher than in those who had MetS (Pbilirubin quartiles were linearly and negatively correlated with MetS prevalence and hypertriglyceridemia (HTG) in females (Pbilirubin was an independent predictor of MetS for females (OR: 0.910, 95%CI: 0.863-0.960; P=0.001). The present study suggests that physiological levels of serum total bilirubin might be an independent risk factor for aged Chinese women, and the prevalence of MetS and HTG are negatively correlated to serum total bilirubin levels.

    It was reported that Vitamin D deficiency was associated with a greater risk of cardiometabolic diseases, obesity, impaired glucose tolerance and diabetes mellitus type 2, arterial hypertension, and dyslipidemia. Apelin is an adipocytokine suspected to have a role in skeletal muscle glucose utilization and glycemic regulation which may be a promising treatment modality for diabetes. It was recently reported that increased mean platelet volume (MPV) was emerging as an independent risk factor for thromboembolism, stroke, and myocardial infarction. In patients with diabetes, MPV was higher compared with the normal glycemic controls; in addition, it has been proposed that an increase in MPV may play a role in the micro- and macro-vascular complications related to diabetes. We postulated that deficiency in Vitamin D levels might be associated with higher MPV and lower serum apelin levels leading a further increase in insulin resistance in diabetic patients. So, we aimed to investigate Vitamin D levels, MPV and serum apelin levels in diabetic patients and their correlations between each other. This is a cross-sectional study design. Seventy-eight patients with Diabetes Mellitus type 2, admitted to our outpatient clinic of internal medicine department at Bezmialem Vakif University, were included in our study. Forty-one patients were female; 37 patients were male. Serum apelin levels, fasting glucose levels, urea, creatinine, triglycerides, total cholesterol, low-density lipoprotein cholesterol (LDL-C), high-density lipoprotein cholesterol (HDL-C), fasting serum insulin level, HbA1c, free T3, free T4, TSH, vitamin D (25-OH Vitamin D) and complete blood counts were analyzed in all subjects. Each sex was analyzed separately. We found that a positive correlation existed between serum apelin levels and BMI in female patients. (r: 0.380, P: 0.014) There was also a significant positive correlation between MPV and HbA1c and fasting glucose levels and a negative correlation

    Full Text Available Aging is associated with a gradual impairment in cognitive function. The elderly also show a high prevalence of undernutrition, whereas nutrition plays an important role in the metabolism of neuronal cells and enzymes. Homocysteine is an amino acid resulting from methionine metabolism and is dependent on intake of vitamin B12, vitamin B6 and folic acid. Homocysteine is said to play a role in cognitive function. The objective of this study was to evaluate the effect of micronutrient supplementation for 6 months on serum homocysteine levels and cognitive function in older people. This study was an experimental study of pre-post test design, carried out in Mampang subdistrict, South Jakarta. A total of 94 elderly people was recruited for this study, consisting of 44 females and 50 males. Serum homocysteine level was assessed by fluorescent polarization immunoassay and cognitive function by means of the mini mental state examination (MMSE before and after micronutrient supplementation. Mean serum homocysteine concentration after supplementation decreased significantly to 14.8 ± 5.8 mmol/L, compared with mean serum homocysteine level of 15.9 ± 5.9 mmol/L before supplementation (p=0.000. Multiple regression analysis indicated that the factors influencing post-supplementation MMSE scores were gender (â=-0.350; p=0.000, education (â=0.510; p=0.000 and post-supplementation homocysteine levels (â=-0.201; p=0.000, while age, pre-supplementation homocysteine levels and BMI did not affect MMSE scores. Homocysteine concentration decreased significantly after 6 months of supplementation. The factors affecting post-supplementation MMSE scores were gender, level of education, and post-supplementation homocysteine level.

  17. Low serum cartonectin/CTRP3 concentrations in newly diagnosed type 2 diabetes mellitus: in vivo regulation of cartonectin by glucose.

    Bo Ban

    Full Text Available OBJECTIVES: Cartonectin is a novel adipokine of the C1q complement/TNF-related protein (CTRP superfamily, with glucose lowering effects, anti-inflammatory and cardio-protective properties. We sought to investigate circulating cartonectin concentrations in subjects with type 2 diabetes mellitus (T2DM as well as age and BMI matched control subjects. We also examined the effects of a 2 hour 75 g oral glucose tolerance test (OGTT on serum cartonectin concentrations in T2DM subjects. DESIGN: Cross-sectional study [newly diagnosed (first discovery, not on any treatments T2DM (n = 47 and control (n = 63 subjects]. Serum cartonectin was measured by ELISA. RESULTS: Serum cartonectin concentrations were significantly lower in patients with T2DM compared to controls (P0.05. There were no significant correlations in T2DM subjects (n = 47. In control subjects (n = 63, serum cartonectin was significantly negatively correlated with CRP, and significantly positively correlated with insulin, HOMA-IR and leptin. However, when subjected to multiple regression analysis, none of these variables were predictive of serum cartonectin (P>0.05. Finally, serum cartonectin concentrations were significantly lower in T2DM subjects after a 2 hour 75 g OGTT (P<0.01. CONCLUSIONS: Cartonectin may serve as a novel biomarker for the prediction and early diagnosis of T2DM patients. Furthermore, cartonectin and/or pharmacological agents that increase circulating cartonectin levels can represent a new therapeutic field in the treatment of T2DM patients. Further research is needed to clarify these points.

  18. Serum uric acid is more strongly associated with impaired fasting glucose in women than in men from a community-dwelling population.

    Full Text Available Serum uric acid (SUA levels are associated with metabolic syndrome (MetS and its components such as glucose intolerance and type 2 diabetes. It is unknown whether there are gender-specific differences regarding the relationship between SUA levels, impaired fasting glucose (IFG and newly detected diabetes. We recruited 1,209 men aged 60±15 (range, 19-89 years and 1,636 women aged 63±12 (range, 19-89 years during their annual health examination from a single community. We investigated the association between SUA levels and six categories according to fasting plasma glucose (FPG level {normal fasting glucose (NFG, <100 mg/dL; high NFG-WHO, 100 to 109 mg/dL; IFG-WHO, 110 to 125 mg/dL; IFG-ADA, 100 to 125 mg/dL; newly detected diabetes, ≥126 mg/dL; known diabetes} SUA levels were more strongly associated with the different FPG categories in women compared with men. In women, the associations remained significant for IFG-WHO (OR, 1.23, 95% CI, 1.00-1.50 and newly detected diabetes (OR, 1.33, 95% CI, 1.03-1.72 following multivariate adjustment. However, in men all the associations were not significant. Thus, there was a significant interaction between gender and SUA level for newly detected diabetes (P = 0.005. SUA levels are associated with different categories of impaired fasting glucose in participants from community-dwelling persons, particularly in women.

    In this study, we explored the effects of consumption of banana in thirty hypercholesterolemic and fifteen type 2 diabetic subjects. They were given a daily dose of 250 or 500 grams of banana for breakfast for 12 weeks. Fasting serum lipid, glucose and insulin levels were measured initially as well as every 4 weeks. Daily consumption of banana significantly lowered fasting blood glucose (from 99 ± 7.7 to 92 ± 6.9 and 102 ± 7.3 to 92 ± 5.7 mg x dL(-1) (p profile in diabetic patients were not statistically significant, but for plasma levels of adiponectin, there were significantly increased (from 37.5 ± 9.36 to 48.8 ± 7.38 ngnml1, p consumption of banana (@ 250 g/day) is harmless both in diabetic and hypercholesterolemic volunteers and marginally beneficial to the later.

  1. May maternal lifestyle have an impact on neonatal glucose levels?

    Hoirisch-Clapauch, Silvia; Porto, Maria Amelia S; Nardi, Antonio E

    2016-02-01

    Neonatal glucose levels correlate negatively with umbilical cord levels of C-peptide, a polypeptide secreted with insulin. In other words, neonatal hypoglycemia results from excessive insulin secretion from fetal/neonatal beta cells. Given that insulin causes fat to be stored rather than to be used for energy, one would expect that chronic hyperinsulinemia would result in large-for-gestational-age neonates. The finding that many small-for-gestational-age neonates have hypoglycemia suggests that the stimulus for insulin production occurs close to delivery. We postulated that a potent stimulation of maternal insulin production close to delivery would also provide a potent stimulus for fetal and neonatal insulin production, causing neonatal hypoglycemia. This study has evaluated 155 mothers with markers of excessive insulin production (such as acanthosis or grade III obesity), or with situations characterized by increased insulin requirements (such as an invasive bacterial infection or use of systemic corticosteroid within a week before delivery; or sedentariness or high-carbohydrate intake within 24h before delivery) and their 158 neonates who were screened for glycemic levels at 1, 2 and 4h after birth. The minimum glucose level was correlated to the maternal parameters, and to classical predictors of neonatal hypoglycemia, such as low-birth weight and preterm delivery. The only independent predictors were sedentariness and high-carbohydrate intake within 24h before delivery. The risk of neonatal hypoglycemia increased five-fold with sedentariness, 11-fold with high-carbohydrate intake, and 329-fold with both risk factors. The risk of neonatal hypoglycemia seems to be highly influenced by maternal lifestyle within 24h before delivery. Controlled randomized trials may help determine whether a controlled carbohydrate diet combined with regular physical activity close to delivery can prevent neonatal hypoglycemia and all its severe complications to the newborn

    This study investigated plasma carnitine levels in patients undergoing allogenic bone marrow transplantation. The patients received fat-based TPN (50% fat, 50% CHO; calorie: nitrogen ratio 125:1) for an average of 33 +/- 7.5 days. TPN was started before transplantation and stopped when patients were able to eat. Caloric needs were estimated using the Harris-Benedict equation; 150% of the estimated BEE was given for the first two weeks after transplantation. The amount of TPN was gradually decreased as patients resumed their oral intake. All patients had low-normal serum carnitine levels before transplantation. There was no significant change in total or free serum carnitine levels during the course of TPN. However, in patients who had symptoms of graft vs. host reaction (GVH), the highest carnitine values during GVH (total 72.3 +/- 6.5 and free 61.2 +/- 12.4 mumol/l) were significantly higher (p < 0.001) than the baseline values (total 27.1 +/- 9.3 and free 24.9 +/- 9.6 mumol/l) or the highest non GVH values after transplantation (total 32.0 +/- 10.7 and free 29.0 +/- 10.7 mumol/l, respectively). The serum triglyceride, total cholesterol, and HDL cholesterol remained within normal range. In conclusion, bone marrow transplant patients receiving fat-based TPN have normal circulating levels of carnitine. GVH reaction caused an increase in the carnitine levels, which was probably due to increased tissue catabolism.

    2016-08-01

    Full Text Available Introduction : Vitiligo is a common acquired pigmentary skin disorder. Vitamin D is responsible for skin pigmentation, increases tyrosinase activity and melanogenesis, and exhibits immunoregulatory functions. Low levels of vitamin D are associated with many autoimmune diseases, including systemic lupus, diabetes mellitus, rheumatoid arthritis, multiple sclerosis and alopecia areata. Few reports have evaluated serum vitamin D levels in vitiligo patients, and their results are conflicting. Aim : To evaluate serum vitamin D levels of vitiligo patients and compare the results with controls. Material and methods : In total, 50 vitiligo patients and 47 controls were enrolled in the study. Vitamin D levels were measured from blood samples. Group comparisons were performed using appropriate statistical methods. Results : The patients had lower serum vitamin D levels than the controls, but this difference was not significant (p = 0.570. Conclusions : It remains unknown whether vitamin D deficiency causes vitiligo. Larger controlled studies are required to prove whether low circulating vitamin D is a causative factor in vitiligo.

    During the past three decades, the incidence of hepatocellular carcinoma in the United States has tripled. The neuroendocrine character has been observed in some tumor cells within some hepatocellular carcinoma nodules and elevated serum chromogranin A also been reported in patients with hepatocellular carcinoma. The aim of this work was to investigate the role of serum concentration of chromogranin A in patients with hepatocellular carcinoma at different stages. The study population consisted of 96 patients (63 males and 33 females age range 52-84) at their first hospital admission for hepatocellular carcinoma. The control group consisted of 35 volunteers (20 males and 15 females age range 50-80). The hepatocellular carcinoma patients were stratified according the Barcelona-Clinic Liver Cancer classification. Venous blood samples were collected before treatment from each patients before surgery, centrifuged to obtain serum samples and stored at -80° C until assayed. The chromogranin A serum levels were elevated (> 100 ng/ml) in 72/96 patients with hepatocellular carcinoma. The serum levels of chromogranin A were significantly correlated (p<0.05) with alpha-fetoprotein. In comparison with controls, the hepatocellular carcinoma patients showed a significant increase (p<0.001) vs controls. The chromogranin A levels in the Barcelona staging of hepatocellular carcinoma was higher in stage D compared to stage C (p<0.01), to stage B (p<0.001), and to stage A (p<0.001). Molecular markers, such as chromogranin A, could be very useful tools for hepatocellular carcinoma diagnosis. However the molecular classification should be incorporated into a staging scheme, which effectively separated patients into groups with homogeneous prognosis and response to treatment, and thus serves to aid in the selection of appropriate therapy.

    Objective: To explore the dynamic of tumor necrosis factor-alpha (TNF-α)and its correlation with insulin resistance (IR)during different stages of gestational diabetes mellitus (GDM). Methods: Thirty-two subjects with GDM and 31 cases of normal pregnant women nonnal glucose tolerance, NGT were enrolled in the study, serum TNF-α and insulin were determined by radioimmunoassay. The plasma glucose was measured by using glucose oxidase. Tests repeated for each group according different stages of prenatal 25-28 weeks, 29-32 weeks, 37-38 weeks and postpartum 6-8 weeks. IR was assessed by the homeostasis model of assessment for insulin resistance index (HOMA-IR). Results: (1)Serum TNF-α levels in CDM and NGT group rose with gestational age, and both significantly decreased at postpartum. (2) Serum TNF-α levels in GDM of above-mentioned four stages respectively were (7.05±0.67) ng/L, (7.11± 0.75) ng/L, (7.36±0.79) ng/L, (5.46±0.37) ng/L respectively. All significantly increased than those in the same stage group (t=7.81, 7.05, 7.15, P<0.01). (3) Maternal serum TNF-α levels were in positive correlation with HOMA-IR in GDM (r=0.571, P<0.05). Conclusions: Serum TNF-α levels in GDM rose with gestational age, but significantly decreased at postpartum. The dynamic changes of serum TNF-α contribute to occurrence of insulin resistance.

    There is evidence that changes in branched-chain amino acid (BCAA) levels may correlate with the efficacy of therapeutic interventions for affecting improvement in metabolic control. The objective of this study was to evaluate whether serum concentrations of BCAAs (leucine, isoleucine, valine) could mediate in insulin sensitivity and glucose tolerance after continuous positive airway pressure (CPAP) treatment in patients with obstructive sleep apnea (OSA). A prospective randomized controlled trial of OSA patients with morbid obesity was conducted. Eighty patients were randomized into two groups: 38 received conservative treatment and 42 received CPAP treatment for 12 weeks. Plasma levels of BCAA, glucose tolerance and insulin resistance were evaluated at baseline and after treatment. After treatment, significant decreases of leucine levels were observed in both groups when compared with baseline levels (P fasting plasma glucose and glycosylated haemoglobin values only in the conservative group (P < 0.05). In summary, we found that the treatment with CPAP for 12 weeks caused similar changes in circulating BCAAs concentrations to conservative treatment and a differential metabolic response of CPAP and conservative treatment was observed between the relationship of BCAAs and glucose homeostasis. Additional studies are needed to determine the interplay between branched-chain amino acids and glucose metabolism in patients with sleep apnea. © 2017 European Sleep Research Society.

    2012-06-01

    Full Text Available Fetuin-A is a calcification inhibitor, negative acute phase response marker and cardiovascular mortality predictor in hemodialysis patients. Low levels of fetuin-A are associated with malnutrition, inflammation, decreased bone mass density, low-turnover bone and use of high calcium concentration dialysate. Hemodialysis procedure (HD has been shown to decrease fetuin-A levels by 20%, probably due to HD-induced inflammation or acute changes in calcium metabolism. The aim of our study was to investigate effects of HD on serum fetuin-A levels. Forty clinically and hemodynamically stable hemodialysis patients (21 females, 68 (38-85 years underwent routine bicarbonate hemodialysis or hemodiafiltration with polysulfone dialyzer. On consecutive HD dialysis solution with different calcium concentration with/without citric acid was used to assess influence of calcium shifts and parathyroid activity on fetuin-A changes during HD. All other parameters of HD were kept constant. Serum fetuin-A, calcium, phosphorus, iPTH, CRP and other biochemical parameters were measured before and after each HD. Our data show that predialysis serum fetuin-A levels have positive correlation with iPTH levels (p<0.05 and tendency to decrease with higher CRP levels. There was no change in fetuin-A levels during HD: 206 (167.1; 231.9 ug/ml before and 208.9 (170.3; 246.3 ug/ml after HD; respectively. When corrected for haemoconcentration, decrease in fetuin-A was only 2.8% (p<0.05. There was also no difference between effect of hemodialysis and hemodia-filtration procedure. The use of different calcium dialysate concentrations had distinct effect on iPTH levels during and after HD, however, we observed no associated changes in fetuin-A levels. The use of dialysate solution with citric acid had no effect on fetuin-A levels. In conclusion, standard bicarbonate HD with polysulfone dialyser and ultrapure dialysate induces only minor changes in fetuin-A and no changes in hsCRP levels

  10. Relationship between fluctuations in glucose levels measured by continuous glucose monitoring and vascular endothelial dysfunction in type 2 diabetes mellitus

    2013-01-01

    Full Text Available Abstract Background Fluctuations in blood glucose level cause endothelial dysfunction and play a critical role in onset and/or progression of atherosclerosis. We hypothesized that fluctuation in blood glucose levels correlate with vascular endothelial dysfunction and that this relationship can be assessed using common bedside medical devices. Methods Fluctuations in blood glucose levels were measured over 24 hours by continuous glucose monitoring (CGM on admission day 2 in 57 patients with type 2 diabetes mellitus. The reactive hyperemia index (RHI, an index of vascular endothelial function, was measured using peripheral arterial tonometry (EndoPAT on admission day 3. Results The natural logarithmic-scaled RHI (L_RHI correlated with SD (r=−0.504; PPP=0.001 and percentage of time ≥200 mg/dl (r=−0.292; P=0.028. In 12 patients with hypoglycemia, L_RHI also correlated with the percentage of time at hypoglycemia (r=−0.589; P=0.044. L_RHI did not correlate with HbA1c or fasting plasma glucose levels. Furthermore, L_RHI did not correlate with LDL cholesterol, HDL cholesterol, and triglyceride levels or with systolic and diastolic blood pressures. Finally, multivariate analysis identified MAGE as the only significant determinant of L_RHI. Conclusions Fluctuations in blood glucose levels play a significant role in vascular endothelial dysfunction in type 2 diabetes. Trial registration UMIN000007581

    Conclusion: Although FA supplementation decreased serum levels of Hcy in different MTHFR genotypes, serum Lp(a was not changed by FA supplements. Our data suggests that FA supplementation effects on serum Hcy is MTHFR genotype independent in pregnant women.

  13. Serum PSA levels in the Indian population: Is it different?

    Agrawal, Amit; Karan, Shailesh Chandra

    2017-04-01

    Serum prostate-specific antigen (PSA) is an important tumour, marker which is widely used to trigger trans-rectal ultrasound (TRUS)-guided prostate biopsy. However, the PSA levels vary with race and ethnicity. Therefore, there is a need to have an Indian reference range. All adult male patients meeting the inclusion and exclusion criteria were enrolled in this study. They were subjected to assessment of serum total PSA, digital rectal examination and trans-abdominal ultrasound. If any one or more of these were found abnormal, then a TRUS-guided 12-core prostate biopsy was done. Patients who were detected to have prostatic cancer were excluded from the final analysis. The data so obtained was grouped among the following three age groups: 40-49, 50-59 and 60-70 years, and the age-specific PSA values, prostatic volume and PSA density were found. A total of 1772 patients were analysed. The mean serum total PSA was 1.76 ng/ml with a standard deviation of 2.566 ng/ml. Group-wise age distribution of the mean serum total PSA was 1.22, 1.97 and 2.08 ng/ml in 40-49, 50-59 and 60-70 years age groups. The mean total PSA and the age-specific PSA range tend to be lower in the Indians than the Western population.

    The adipokine progranulin has metabolic proprieties, playing a role in obesity and insulin resistance. Its levels seems to be dependent of renal function, since higher progranulin concentration is observed in patients with end-stage kidney disease. However, the effect of kidney transplantation on progranulin remains unknown. To assess the serum progranulin levels in kidney transplant recipients before and after kidney transplantation. Forty-six prospective kidney transplant recipients were included in this longitudinal study. They were evaluated before transplantation and at three and twelve months after transplantation. Clinical, anthropometric and laboratorial measurements were assessed. Progranulin was determined with enzyme-linked immunosorbent assays. Serum progranulin significantly decreased in the early period after transplantation (from 72.78 ± 2.86 ng/mL before transplantation to 40.65 ± 1.49 ng/mL at three months; pProgranulin was associated with waist circumference and fasting plasma glucose after adjusted for age, gender, study period, glomerular filtration rate, interleukin-6, high sensitivity C reactive protein and adiponectin. Progranulin serum levels are increased before transplantation and a reduction is observed in the early period after transplantation, possibly attributed to an improvement in renal function. At one year after transplantation, an increment in progranulin is observed, seems to be independent of glomerular filtration, and remained significantly lower than before transplantation.

    Background There exist controversies about the health effects of coconut. Fresh coconut consumption on human health has not been studied substantially. Fresh coconut consumption is a regular part of the diet for many people in tropical countries like India, and thus there is an increasing need to understand the effects of fresh coconut on various aspects of health. Aim To compare the effects of increased saturated fatty acid (SFA) and fiber intake, provided by fresh coconut, versus monounsaturated fatty acid (MUFA) and fiber intake, provided by a combination of groundnut oil and groundnuts, on anthropometry, serum insulin, glucose levels and blood pressure in healthy adults. Materials Eighty healthy volunteers, randomized into two groups, were provided with a standardized diet along with either 100 g fresh coconut or an equivalent amount of groundnuts and groundnut oil for a period of 90 days. Assessments such as anthropometric measurements, blood pressure, blood sugar and insulin levels were performed before and after the supplementation period. Results Results of this study showed a significant reduction in fasting blood sugar (FBS) in both the groups. However, a significant reduction in body weight was observed in the coconut group, while a significant increase in diastolic pressure was observed in the groundnut group. Conclusions Results of this study suggest that fresh coconut-added diet helps reduce blood glucose levels and body weight in normal healthy individuals.

  16. Elevated serum angiotensin converting enzyme levels in metastatic ovarian dysgerminoma.

    Cotter, T P

    2012-02-03

    A case of a 32-year-old XY genotype female is described, presenting with mediastinal and abdominal lymphadenopathy and associated with an elevated serum angiotensin I converting enzyme (SACE) level. Lymph node histology showed a malignant dysgerminoma of ovarian origin. Combined chemotherapy led to a radiological regression of the lymphadenopathy and coincided with a decrease in SACE concentration. The authors suggest that SACE may be a marker for disseminated germinoma tumours and may be useful for monitoring treatment.

    Background Exposure to pesticides has been reported to increase the risk of Parkinson disease (PD), but identification of the specific pesticides is lacking. Three studies have found elevated levels of organochlorine pesticides in postmortem PD brains. Objective To determine whether elevated levels of organochlorine pesticides are present in the serum of patients with PD. Design Case-control study. Setting An academic medical center. Participants Fifty patients with PD, 43 controls, and 20 patients with Alzheimer disease. Main Outcome Measures Levels of 16 organochlorine pesticides in serum samples. Results β-Hexachlorocyclohexane (β-HCH) was more often detectable in patients with PD (76%) compared with controls (40%) and patients with Alzheimer disease (30%). The median level of β-HCH was higher in patients with PD compared with controls and patients with Alzheimer disease. There were no marked differences in detection between controls and patients with PD concerning any of the other 15 organochlorine pesticides. Finally, we observed a significant odds ratio for the presence of β-HCH in serum to predict a diagnosis of PD vs control (odds ratio, 4.39; 95% confidence interval, 1.67–11.6) and PD vs Alzheimer disease (odds ratio, 5.20), which provides further evidence for the apparent association between serum β-HCH and PD. Conclusions These data suggest that β-HCH is associated with a diagnosis of PD. Further research is warranted regarding the potential role of β-HCH as a etiologic agent for some cases of PD.

    2013-04-01

    In the present study, the effect of intrathecal (i.t.) or intracerebroventricular (i.c.v.) administration with cholera toxin (CTX) on the blood glucose level was examined in ICR mice. The i.t. treatment with CTX alone for 24 h dose-dependently increased the blood glucose level. However, i.c.v. treatment with CTX for 24 h did not affect the blood glucose level. When mice were orally fed with D-glucose (2 g/kg), the blood glucose level reached to a maximum level at 30 min and almost returned to the control level at 120 min after D-glucose feeding. I.c.v. pretreatment with CTX increased the blood glucose level in a potentiative manner, whereas i.t. pretreatment with CTX increased the blood glucose level in an additive manner in a D-glucose fed group. In addition, the blood glucose level was increased in formalin-induced pain animal model. I.c.v. pretreatment with CTX enhanced the blood glucose level in a potentiative manner in formalin-induced pain animal model. On the other hand, i.t. pretreatment with CTX increased the blood glucose level in an additive manner in formalin-induced pain animal model. Our results suggest that CTX administered supraspinally or spinally differentially modulates the regulation of the blood glucose level in D-glucose fed model as well as in formalin-induced pain model.

  19. Serum Bile Acids Are Higher in Humans With Prior Gastric Bypass: Potential Contribution to Improved Glucose and Lipid Metabolism

    Patti, Mary-Elizabeth; Houten, Sander M.; Bianco, Antonio C.; Bernier, Raquel; Larsen, P. Reed; Holst, Jens J.; Badman, Michael K.; Maratos-Flier, Eleftheria; Mun, Edward C.; Pihlajamaki, Jussi; Auwerx, Johan; Goldfine, Allison B.

    The multifactorial mechanisms promoting weight loss and improved metabolism following Roux-en-Y gastric bypass (GB) surgery remain incompletely understood. Recent rodent studies suggest that bile acids can mediate energy homeostasis by activating the G-protein coupled receptor TGR5 and the type 2 thyroid hormone deiodinase. Altered gastrointestinal anatomy following GB could affect enterohepatic recirculation of bile acids. We assessed whether circulating bile acid concentrations differ in patients who previously underwent GB, which might then contribute to improved metabolic homeostasis. We performed cross-sectional analysis of fasting serum bile acid composition and both fasting and post-meal metabolic variables, in three subject groups: (i) post-GB surgery (n = 9), (ii) without GB matched to preoperative BMI of the index cohort (n = 5), and (iii) without GB matched to current BMI of the index cohort (n = 10). Total serum bile acid concentrations were higher in GB (8.90 ± 4.84 µmol/l) than in both overweight (3.59 ± 1.95, P = 0.005, Ov) and severely obese (3.86 ± 1.51, P = 0.045, MOb). Bile acid subfractions taurochenodeoxycholic, taurodeoxycholic, glycocholic, glycochenodeoxycholic, and glycodeoxycholic acids were all significantly higher in GB compared to Ov (P fasting triglycerides (r = −0.40, P = 0.05), and positively correlated with adiponectin (r = −0.48, P < 0.02) and peak glucagon-like peptide-1 (GLP-1) (r = 0.58, P < 0.003). Total bile acids strongly correlated inversely with thyrotropic hormone (TSH) (r = −0.57, P = 0.004). Together, our data suggest that altered bile acid levels and composition may contribute to improved glucose and lipid metabolism in patients who have had GB. PMID:19360006

    2015-07-01

    The present study was conducted to compare serum leptin and insulin resistance levels between Korean postmenopausal long-term semi-vegetarians and non-vegetarians. Subjects of this study belonged to either a group of postmenopausal vegetarian women (n = 54), who maintained a semi-vegetarian diet for over 20 years or a group of non-vegetarian controls. Anthropometric characteristics, serum leptin, serum glucose, serum insulin, insulin resistance (HOMA-IR; Homeostasis Model Assessment of Insulin Resistance), and nutrient intake were compared between the two groups. The vegetarians showed significantly lower body weight (p vegetarians. The HOMA-IR of the vegetarians was significantly lower than that of the non-vegetarians (p vegetarian diet might be related to lower insulin resistance independent of the % of body fat in postmenopausal women.

    Among the pregnancy urinary tract infections, asymptomatic bacteriuria (ASB) is the most common one. Untreated ASB can progress to pyelonephritis in 30-50% of the patients and can also result in prematurity in 27% of the pregnancy so it needs immediate diagnosis and treatment. In this study, we wanted to evaluate procalcitonin levels, compared to other inflammatory in pregnant women with ASB. The study was designed between the period of January 2012 and February 2013 at Sakarya University School of Medicine, Department of Gynecology and Obstetrics. The study population included 30 pregnant patients with asymptomatic bacteriuria and 39 healthy pregnant controls. Mean age was 28 (SD, 5.5) of the study population; mean maternal weight was 70 (SD, 8) kilogram. There were no statically significant differences between the groups according to the routine biochemical parameters, but gestational age was significantly lower in the ASB group compared to the controls (20.4 vs 28.6, respectively; p 0.05 ng/ml and 21(70%) patients had negative procalcitonin levels (Chi-squrae, p treatment of the first ASB diagnosis. Procalcitonin levels were significantly higher in ASB group than the control group and serum procalcitonin levels were higher in pregnant women with recurrent ASB. This finding is an important result revealed that high procalcitonin level can predict the further urinary tract infection risk. Finally, serum procalcitonin levels were normal in healthy pregnant women while other inflammatory markers such as WBC, ESR and CRP levels were higher.

    Full Text Available Background / objectives. Hyaluronic acid (HA is rarely described in dermatomyositis (DM. Thus, we determined any clinical association of serum levels of hyaluronic acid (HA in patients with dermatomyositis (DM. Materials and Methods. This cross-sectional single-center analysis 75 DM and 75 healthy individuals, during the period from January 2012 to July 2013. An anti-HA antibody assay was performed using specific ELISA/EIA kits, according to the manufacturer’s protocol. Results. The patients with DM and control subjects had comparable demographic distributions (p>0.05. The median time duration between disease diagnosis and initial symptoms was 6.0 [3.0-12.0] months, with a median DM disease duration of 4.0 [1.0-7.0] years. The median level of serum HA was significantly increased in patients with DM compared to the control group [329.0 (80.0-958.0 vs. 133.0 (30.0-262.0 ng/mL, respectively; p0.05. Serum HA also did not correlate with gender, ethnicity, auto-antibodies or drug use (p>0.05, but did correlate with cutaneous features, such as photosensitivity (p=0.001, “shawl” sign (p=0.018, “V-neck” sign (p=0.005 and cuticular hypertrophy (p=0.014. Conclusions. A high level of serum AH was observed in DM compared to healthy individuals. In DM, HA did not correlate to demographic, auto-antibodies and therapy parameters. However, HA correlated specifically with some cutaneous features, suggesting that this glycosaminoglycan could be involved in modulating cutaneous inflammation in this population. More studies are necessary to understand the correlation between AH and patients with DM.

    To compare the serum AMH levels between women with and without insulin resistance (IR) in polycystic ovary syndrome (PCOS). 293 women with PCOS according to the Rotterdam criteria were enrolled into our study. Insulin resistance was diagnosed according to the Homeostatic model assessment insulin resistant (HOMA-IR) formula and the cut-off point was set to more than 2.5. Women were grouped according to the presence of insulin resistance (IR) (HOMA-IR ≥ 2.5). Serum AMH and other hormones were compared between the IR (+) and IR (-) groups. Additionally, AMH percentiles were (75) constructed; HOMA-IR and BMI values in women with/without IR were compared in different percentiles. Further, HOMA-IR, BMI and AMH values were measured across different PCOS phenotypes. The prevalence of IR was 45%. The prevalence of IR was 57% in women with BMI ≥ 25. Serum AMH levels were not significantly different among women with and without IR. Also, HOMA-IR values were not significant among different AMH percentiles. However, in each AMH percentile BMI were found to be higher in women with IR than in women without IR. The median HOMA-IR values were the highest in women with BMI ≥ 25 in both IR (+) and IR (-) groups. No significant difference was found among PCOS phenotypes in terms of HOMA-IR and BMI. Positive correlations were found between BMI, free testosterone and HOMA-IR. However, no correlation was found between AMH and HOMA-IR. The serum AMH levels between women with IR and without IR in PCOS were not significantly different. Also, we did not reveal a correlation between serum AMH levels and IR in women with PCOS. IR was not correlated with different PCOS phenotypes either. We found a positive correlation between BMI and IR. IR should be investigated in women with PCOS having a BMI ≥ 25, independent of their phenotype or AMH levels. Copyright © 2018 Elsevier B.V. All rights reserved.

    Conclusion:-Saliva can be used as a routine potential diagnostic tool in assessing diabetes mellitus, the most prevalent among Indian population. It is a simple and non invasive technique in screening and monitoring of this disease. Repeated painful pricks, hazard of getting infections, complications in hemophiliac patients and various other disadvantages that involve the blood tests currently used for diagnosis and monitoring of this widely prevalent Diabetes mellitus disease, can be replaced by non invasive tests involving Saliva, which is also a cost effective.

    2017-02-01

    We investigated, at diagnosis, the relationship between serum immunoglobulin G4 levels and the main characteristics of Graves' disease: hyperthyroidism severity, goiter size, presence of active Graves' ophthalmopathy, antithyroid antibodies status, and titer. This prospective study included 80 newly diagnosed Graves' disease patients. The main parameters measured at diagnosis: thyroid-stimulating hormone, free thyroxine, free triiodothyronine, total triiodothyronine, thyroglobulin, antithyroid peroxidase antibodies, anti-thyroglobulin antibodies, thyroid-stimulating hormone receptor antibodies, immunoglobulin G4. In Graves' disease patients, serum immunoglobulin G4 levels were higher than in general population (p = 0.028) and higher in men compared to women (p = 0.002). Only one female patient with intense hypoechoic goiter, high anti-thyroglobulin antibody, and antithyroid peroxidase antibody titers had an elevated serum immunoglobulin G4 level at diagnosis. Patients with immunoglobulin G4 levels above the 75th percentile (>237.52 mg/dl, N = 20) were younger at Graves' ophthalmopathy onset (p 286.28 mg/dl, N = 8) had lower total triiodothyronine values (p = 0.001) than patients with IgG below the 90th percentile. No significant correlations were found between smoking status (p = 0.58), goiter size (p = 0.50), the presence of ophthalmopathy (p = 0.42) or thyroid-stimulating hormone receptor antibody titers (p = 0.45) and the mean value of immunoglobulin G4 levels at diagnosis. Our data suggest that Graves' disease patients with elevated immunoglobulin G4 levels at diagnosis have a phenotype characterized by higher anti-thyroglobulin antibody and antithyroid peroxidase antibody titers, less severe T3 hyperthyroidism, younger age at ophthalmopathy onset and require a shorter duration of the first methimazole treatment cycle.

    Full Text Available Ischemic cerebrovascular disease is one of the most common causes of death in the world. Recent interests have been focused on natural antioxidants and anti-inflammatory agents as potentially useful neuroprotective agents. Diospyros kaki (persimmon has been shown to exert anti-inflammatory, antioxidant, and antineoplastic effects. However, its effects on ischemic damage have not been evaluated. Here, we used an in vitro model of cerebral ischemia and studied the effects of hydroalcoholic extract of peel (PeHE and fruit pulp (PuHE of persimmon on cell viability and markers of oxidative damage mainly intracellular reactive oxygen species (ROS induced by glucose-oxygen-serum deprivation (GOSD in PC12 cells. GOSD for 6 h produced significant cell death which was accompanied by increased levels of ROS. Pretreatment with different concentrations of PeHE and PuHE (0–500 μg/mL for 2 and 24 h markedly restored these changes only at high concentrations. However, no significant differences were seen in the protection against ischemic insult between different extracts and the time of exposure. The experimental results suggest that persimmon protects the PC12 cells from GOSD-induced injury via antioxidant mechanisms. Our findings might raise the possibility of potential therapeutic application of persimmon for managing cerebral ischemic and other neurodegenerative disorders.

    2014-11-01

    Full Text Available The aim of this study was to compare the kinetics of the glycoxidation of bovine serum albumin (BSA as a model protein by three sugars: glucose, fructose and ribose, using fluorometric measurements of the content of advanced glycation end products (AGEs, protein-bound fructosamine, dityrosine, N'-formylkynurenine, kynurenine, tryptophan, the content of advanced oxidation protein products (AOPP, protein carbonyl groups, as well as thiol groups. Moreover, the levels of glycoalbumin and AGEs were determined by using an enzyme-linked immunosorbent assay. Based on the kinetic results, the optimal incubation time for studies of the modification of the glycoxidation rate by additives was chosen, and the effects of 25 compounds of natural origin on the glycoxidation of BSA induced by various sugars were examined. The same compounds were found to have different effects on glycoxidation induced by various sugars, which suggests caution in extrapolation from experiments based on one sugar to other sugars. From among the compounds tested, the most effective inhibitors of glycoxidation were: polyphenols, pyridoxine and 1-cyano-4-hydroxycinnamic acid.

    2013-01-01

    Objective: To study serum levo-carnitine (l-carnitine) levels and isometric contraction, force frequency relationship and fatigue of rodent skeletal muscles in type 2 diabetes mellitus. Study Design: Randomized controlled trial. Place and Duration of Study: Physiology Department, Army Medical College, Rawalpindi, from January 2009 to January 2010. Methodology: Sixty Sprague-Dawley rats were randomly divided into two groups; group I (control), fed on normal diet ad libitum and Group II (diabetic), fed on high fat diet and administered streptozocin to induce type 2 diabetes mellitus (T2DM). At 21st day, plasma glucose and TG/HDL ratio were measured to confirm the development of T2DM in group II. At 28th day, blood was drawn by intracardiac puncture to estimate serum levo-carnitine levels. Contractile functions of skeletal muscles were assessed by using iWorx AHK/214 physiological data acquisition unit. Simple muscle twitches, maximum isometric twitch tension (MITT), time-to-peak twitch tension (TPTT) and time-to-relax to 50% of the peak twitch tension (1/2RT) of extensor digitorum muscles were recorded. Muscles were stimulated at higher frequencies to determine maximum fused tetanic tension (MFTT), maximum fused tetanic tension after fatigue protocol (TTFP) and recovery from fatigue (RF). Results: Serum levo-carnitine level decreased significantly in the diabetic group. Both groups had similar MITT, TPTT and 1/2RT but decline in MFTT, TTFP and RF was significant in the diabetic rats. Conclusion: T2DM adversely affected serum levo-carnitine levels and the contractile functions of rodent skeletal muscle at high frequency stimulation. (author)

    Objective: To explore the degree of insulin resistance and β-cell secretory function impairment in close (1st degree) relations of patients with type 2 diabetes (DMII). Methods: Serum true insulin (TI), pro-insulin (PI), immunoreactive insulin (IRI) levels at fasting and after oral 75g glucose loading were determined in: 1) patients with DM 2, n=65 2)relations of DM 2 patients with impaired glucose tolerance (IGT), n=34 3) relations of DM 2 patients with normal glucose tolerance (NGT), n=66 and 4) controls, n=48. HOMA-IR and HOMA-β cell secretory indices were calculated from the data. Results: Fasting serum PI levels were significantly higher in DM 2 patients, relations with IGT and NGT than those in the controls (t=2.38, t=2.16, t=1.95, P 1 C percentages were significantly higher in DM 2 patients and IGT, NGT groups than those in controls (t=3.67, t=2.45, t=1.97, P 1 C percentage, fasting TI and IRI levels. Conclusion: Insulin resistance was already obvious in those relations of DM 2 patients with normal glucose tolerance and β-cell secretory function impairment was also present. Early intervention in these subjects might be beneficial. (authors)

    The aim of the present study was to investigate the relationship between the blood IL-6 level, the blood glucose level, and glucose control in septic patients. This retrospective observational study in a general ICU of a university hospital included a total of 153 patients with sepsis, severe sepsis, or septic shock who were admitted to the ICU between 2005 and 2010, stayed in the ICU for 7 days or longer, and did not receive steroid therapy prior to or after ICU admission. The severity of stress hyperglycemia, status of glucose control, and correlation between those two factors in these patients were investigated using the blood IL-6 level as an index of hypercytokinemia. A significant positive correlation between blood IL-6 level and blood glucose level on ICU admission was observed in the overall study population (n = 153; r = 0.24, P = 0.01), and was stronger in the nondiabetic subgroup (n = 112; r = 0.42, P glucose control (blood glucose level blood IL-6 level on ICU admission (P blood IL-6 level after ICU admission remained significantly higher and the 60-day survival rate was significantly lower in the failed glucose control group than in the successful glucose control group (P blood IL-6 level was correlated with hyperglycemia and with difficulties in glucose control in septic patients. These results suggest the possibility that hypercytokinemia might be involved in the development of hyperglycemia in sepsis, and thereby might affect the success of glucose control.

  11. The effect of exercise training modality on serum brain derived neurotrophic factor levels in individuals with type 2 diabetes.

    Damon L Swift

    Full Text Available Brain derived neurotrophic factor (BDNF has been implicated in memory, learning, and neurodegenerative diseases. However, the relationship of BDNF with cardiometabolic risk factors is unclear, and the effect of exercise training on BDNF has not been previously explored in individuals with type 2 diabetes.Men and women (N = 150 with type 2 diabetes were randomized to an aerobic exercise (aerobic, resistance exercise (resistance, or a combination of both (combination for 9 months. Serum BDNF levels were evaluated at baseline and follow-up from archived blood samples.Baseline serum BDNF was not associated with fitness, body composition, anthropometry, glucose control, or strength measures (all, p>0.05. Similarly, no significant change in serum BDNF levels was observed following exercise training in the aerobic (-1649.4 pg/ml, CI: -4768.9 to 1470.2, resistance (-2351.2 pg/ml, CI:-5290.7 to 588.3, or combination groups (-827.4 pg/ml, CI: -3533.3 to 1878.5 compared to the control group (-2320.0 pg/ml, CI: -5750.8 to 1110.8. However, reductions in waist circumference were directly associated with changes in serum BDNF following training (r = 0.25, p = 0.005.Serum BDNF was not associated with fitness, body composition, anthropometry, glucose control, or strength measures at baseline. Likewise, serum BDNF measures were not altered by 9 months of aerobic, resistance, or combination training. However, reductions in waist circumference were associated with decreased serum BDNF levels. Future studies should investigate the relevance of BDNF with measures of cognitive function specifically in individuals with type-2 diabetes.

    2015-05-01

    Full Text Available background: This study aimed to determine serum Bisphenol A (BPA concentrations in patients with dilated cardiomyopathy (DCM as well as the association between serum BPA and several hormonal parameters in DCM patients compared with a healthy control group. Materials and methods: Eighty-eight DCM patients and 88 age- and gender-matched healthy controls were included. Serum BPA levels and several hormonal parameters (including total testosterone (T, sex hormone-binding globulin (SHBG and estradiol (E2 were measured by using corresponding ELISA Kits. The free androgen index (FAI was calculated by the formula: total T in nmol/L × 100/SHBG in nmol/L. Results: BPA levels in the total DCM group were significantly higher compared with that in the controls (6.9 ± 2.7 ng/mL vs. 3.8 ± 1.9 ng/mL, p < 0.001. Significant difference was also observed in SHBG and FAI between DCM patients and controls, (76.9 ± 30.9 nM/L vs. 41.0 ± 15.6 nM/L and 2.9 ± 3.5 vs.5.3 ± 2.6, respectively, both of p < 0.001. Similar trends were observed in the male and female subgroup. Mean T level was lower in DCM group than in control group (540.8 ± 186.0 pg/mL vs. 656.3 ± 112.9 pg/mL, p < 0.001. Linear regression analysis has shown that increasing serum BPA levels were statistically significantly associated with increased SHBG levels. However, no statistical difference was noted for E2. Conclusion: Our findings firstly demonstrated that BPA exposure increased in DCM patients compared with that in healthy controls, while FAI and T levels decreased. SHBG presented a positive association with BPA. It is concluded that hormone disorder induced by BPA exposure might be an environmental factor in the pathology of DCM.

  13. Tributyltin exposure alters cytokine levels in mouse serum.

    Lawrence, Shanieek; Pellom, Samuel T; Shanker, Anil; Whalen, Margaret M

    2016-11-01

    Tributyltin (TBT), a toxic environmental contaminant, has been widely utilized for various industrial, agricultural and household purposes. Its usage has led to a global contamination and its bioaccumulation in aquatic organisms and terrestrial mammals. Previous studies suggest that TBT has debilitating effects on the overall immune function of animals, rendering them more vulnerable to diseases. TBT (at concentrations that have been detected in human blood) alters secretion of inflammatory cytokines from human lymphocytes ex vivo. Thus, it is important to determine if specified levels of TBT can alter levels of cytokines in an in vivo system. Mice were exposed to biologically relevant concentrations of TBT (200, 100 or 25 nM final concentrations). The quantitative determination of interferon (IFN)-γ, tumor necrosis factor (TNF)-α, interleukin (IL)-1β, IL2, IL5, IL7, IL12βp40, IL13, IL15, keratinocyte chemoattractant (KC), macrophage inflammatory protein 1β (MIP), MIP2 and regulated on activation normal T-cell-expressed and secreted (RANTES) was performed in mouse sera by MAGPIX analysis and Western blot. Results indicated alterations (both decreases and increases) in several cytokines. The pro-inflammatory cytokines IFNγ, TNFα, IL-1β, IL-2, IL5, IL12βp40 and IL-15 were altered as were the chemokines MIP-1 and RANTES and the anti-inflammatory cytokine IL-13. Increases in IFNγ and TNFα were seen in the serum of mice exposed to TBT for less than 24 h. Levels of IL1β, IL-12 βp40, IL-5 and IL-15 were also modulated in mouse serum, depending on the specific experiment and exposure level. IL-2 was consistently decreased in mouse serum when animals were exposed to TBT. There were also TBT-induced increases in MIP-1β, RANTES and IL-13. These results from human and murine samples clearly suggest that TBT exposures modulate the secretion inflammatory cytokines.

    Elevated circulating ferritin has been reported to increase the risk of gestational diabetes mellitus (GDM). When high ferritin translates into high iron stores, iron excess is also a condition leading to free radical damage. We aimed to evaluate the relationship between oxidative stress (OS) induced by iron status and GDM risk in non iron-supplemented pregnant women. This was a pilot observational study conducted on 93 non-anemic pregnant women. Iron status was assessed at the first trimester of gestation. Blood sampling was done at 24-28 weeks' gestation for oral glucose tolerance test (OGTT), insulin and biological markers of oxidative damage tests. A significant increase in DNA damage was found in patients who developed GDM. Women with elevated DNA damage had a six-fold increased risk of developing GDM (Exp (B)=6.851, P=0.038; 95% CI [1.108-42.375]). The serum ferritin levels at first trimester were significantly correlated to lipid peroxidation (rho=0.24, p=0.012). The stratified analysis suggests that ferritin is a modifying factor for the correlation of oxidative stress (OS) and glucose intolerance. Moderate ferritin levels due to iron intake without iron-supplement, at early pregnancy is a modifying factor for the correlation of oxidative damage and glucose intolerance in pregnant women. Larger studies to evaluate the risk of food iron intake induced increased oxidative damage in offspring are warranted to propose nutrition advice regarding iron intake in women with a high risk of GDM.

    Khan, Kalyan; Saha, Ashis Ranjan

    2013-02-01

    The study of the biochemical parameters of cord blood acts as a mirror, which usually reflects the neonatal status. The widely used system for the evaluation of a neonate is the Apgar score. There is no comprehensive published data which has established the association between the cord blood glucose level and the Apgar score. Similarly, there is also no well accepted reference range of the cord blood glucose level. The main objectives of the present study was to ascertain any adverse effects of an abnormal cord blood glucose level on the neonatal status and to find out a standard reference level of glucose in cord blood. The cord blood glucose estimation was done by using the glucose oxidase peroxidase method and the statistical analysis was performed by using the SPSS, version 16 software. In the present study, the cord blood glucose level was found to have no correlation with the Apgar scores which were calculated at both one minute and five minutes after birth. It was also found that for the foetus to be free from any obvious complication, the cord blood glucose level had to be around 87 mg/dl. The fluctuations in the maternal glucose levels are weakly associated with the glucose level in the cord blood.

    Objectives: The aim of this study was to evaluate liver function in patients with type 2 diabetes mellitus (T2DM) with and without metabolic syndrome (MS) by determining serum levels of gamma glutamyltransferase (GGT), alanine aminotransferase (ALT) and aspartate aminotransferase (AST). We also investigated correlation between levels of liver enzymes and some components of MS in both groups of patients. Methods: This cross-sectional study included 96 patients (age 47–83 years) with T2DM. All patients were divided according to the criteria of the National Cholesterol Education Program (NCEP) in two groups: 50 patients with T2 DM and MS (T2DM-MS) and 46 patients with T2DM without MS (T2DM-Non MS). The analysis included blood pressure monitoring and laboratory tests: fasting blood glucose (FBG), total lipoprotein cholesterol (TC), high-density lipoprotein cholesterol (HDL-C), triglyceride (TG), fibrinogen and liver enzymes: GGT, ALT and AST. T2DM-MS group included patients which had FBG ≥ 6,1 mmol/L, TG ≥ 1,7 mmol/L and blood pressure ≥ 130/85 mm Hg. Results: T2DM-MS patients had significant higher values of systolic blood pressure, diastolic blood pressure and medium arterial pressure compared to T2DM-Non MS patients. Serum levels of TC, TG, LDL-C, VLDL-C and FBG were significantly higher in the T2DM-MS group compared to the T2DM-Non MS group. Serum fibrinogen level and GGT level were significantly higher in patients with T2DM-MS compared to the serum fibrinogen level and GGT level in T2DM-Non MS patients. Mean serum AST and ALT level were higher, but not significantly, in patients with T2DM and MS compared to the patients with T2DM without MS. Significant negative correlations were observed between TC and AST (r= -0,28, p<0,05), as well as between TC and ALT level (r= -0,29, p<0,05) in T2DM-MS group of patients. Conclusion: These results suggest that patients with T2DM and MS have markedly elevated liver enzymes. T2DM and MS probably play a role in

    Carcinoembryonic Antigen is one of most frequently checked tumor markers in cancer management. We performed statistical analysis with serum CEA data of 2626 persons who received regular health examination and were thought to be free of active disease to determine the cutoff values of serum CEA level in normal Korean adults and to study the factors influencing serum CEA levels in normal subjects. 1) The cutoff values of serum CEA in normal Korean adults in general were 9.28 ng/ml for men, 5.90 ng/ml for women. 2) Serum CEA level was influenced by age, present smoking history, sex, and abnormal findings in chest X ray. 3) Serum CEA level had no correlation with the history of amount of alcohol consumption or obesity. 4) Cutoff values of serum CEA in normal Korean adults were tabulated according to age, sex, and smoking history. Serum CEA level was influenced by age, sex, present smoking history and abnormal findings in chest X ray and cutoff values of serum CEA were tabulated according to age, sex, and smoking history.

    Stress has a considerable impact on welfare and productivity of fish, and blood glucose level of fish may be a factor modulating stress response. This study evaluated the effect of blood glucose level and handling on acute stress response of grass carp Ctenopharyngodon idella. Fish were intraperitoneally injected with glucose at 0, 0.2, 0.5, and 1.0 mg g -1 body mass (BM) and then were exposed to handling for 5 min. Glucose injection resulted in increase of plasma glucose level and liver glycogen content and decrease of plasma lactate level. Handling resulted in increase of plasma levels of cortisol, glucose, and lactate and plasma lactic dehydrogenase (LDH) activity and decrease of liver glycogen content. At 1 h post-stress, the plasma cortisol level was lower in the stressed fish injected with glucose at 0.5 mg g -1 BM than the stressed fish injected with glucose at 0, 0.2, and 1.0 mg g -1 BM. No significant differences were found in the activities of phosphoenolpyruvate carboxykinase (PEPCK) and pyruvate kinase (PK) in the liver between the stressed and unstressed fish, regardless of the dose of glucose injection. At 1 h post-stress, the liver glucose-6-phosphatase (G6Pase) activity was higher in the fish without glucose injection than in the fish injected with glucose. This study reveals that blood glucose level can affect stress response of grass carp by modulating cortisol release and glucose homeostasis through glycogen metabolism and gluconeogenesis in the liver.

  19. Serum glycated albumin is inversely influenced by fat mass and visceral adipose tissue in Chinese with normal glucose tolerance.

    Feifei Wang

    Full Text Available BACKGROUND: Recent studies have revealed that body mass index (BMI inversely influenced serum glycated albumin (GA, which may cause an underestimation of GA-monitored short-term hyperglycemic control. OBJECTIVE: This study was to investigate the association between anthropometric variables (BMI and waist circumference (W and accurate adiposity variables (percentage of body fat (%fat, fat mass, free fat mass (FFM, subcutaneous fat area (SFA, and visceral fat area (VFA with serum GA. DESIGN: A total of 2563 subjects (1037 men, 593 premenopausal women, and 933 postmenopausal women with normal glucose tolerance underwent bioelectrical impedance body fat content measurement and magnetic resonance imaging. Serum GA and absolute value of GA (aGA were measured by enzymatic assay. RESULTS: Compared to the BMI <25.0 kg/m(2 group, the BMI ≥25.0 kg/m(2 group had significantly higher fasting plasma glucose, glycated hemoglobin A1c, and body fat parameters including W, %fat, fat mass, FFM, SFA, and VFA, but significantly lower aGA, and GA in all the three sex- and menopause-stratified groups (all P<0.05. GA decreased with the increment of fat mass for all three groups (all P for trend <0.001. In the same BMI category, men and postmenopausal women with elevated %fat (men, ≥25%; women, ≥35% still had significantly lower GA than those with normal %fat (men, <25%; women, <35% (all P<0.05. Multiple stepwise regression showed that %fat, fat mass, and VFA were independently associated with GA. CONCLUSIONS: Serum GA was inversely influenced by fat mass and visceral adipose tissue in Chinese with normal glucose tolerance.

    Corticosteroid injections are used to treat a variety of orthopedic conditions with the goal of decreasing pain and inflammation. Administration of systemic or local corticosteroids risks temporarily increasing blood glucose levels, especially diabetic patients. The purpose of this study is to quantify the effects of corticosteroid injections on blood glucose levels in diabetic patients with shoulder pathology. Diabetic patients who regularly monitored their blood glucose levels and were indicated for a subacromial corticosteroid injection were included in this prospective investigation. The typical normal morning fasting glucose and most recent hemoglobin A1c level was recorded for each patient. After injection, patients were contacted daily to confirm their fasting morning glucose level for 10 days post-injection. Seventeen consecutive patients were enrolled. Patients with hemoglobin A1c of patients' glucose levels returned to near baseline levels around post-injection day 8, while poorly controlled patients levels remained elevated. Similarly, insulin-dependent diabetic patients had an average increase in fasting glucose level of 99 mg/dL versus 50 mg/dL in non-insulin-dependent diabetic patients ( P patients with well-controlled diabetes experience smaller elevations and faster return to baseline glucose levels than patients with poor control. Insulin dependent diabetics experienced similar findings as patients with poor control. Future studies are needed to evaluate dosing to optimize the risks of blood glucose elevation while maintaining therapeutic benefit.

    Cortisol measurement is indicated in suspected over or under production of cortisol by the adrenal cortex. The finding of low cortisol can create concern and initiate further investigations for the exclusion of adrenal insufficiency. Cushing's syndrome is frequently included in the differential diagnosis of obesity. Some literature describes reduced serum cortisol levels in obesity, however, this is not a well-recognized phenomenon. The aim of this study was to determine the relationship between body mass index (BMI) and serum cortisol levels. Seventy healthy participants agreed to take part in the study. The anthropometric measurements (weight, height, and waist and hip circumferences) were done. Exclusion criteria include those with a history of adrenal/pituitary disease or medications altering cortisol level. The basal cortisol (BC) sample was taken at 8 a.m. immediately before administration of an intravenous bolus injection of 250 μg adrenocorticotropic hormone (ACTH). BMI categories were defined as normal and high if BMI was 18.5-24.99 kg/m² and ≥ 25 kg/m², respectively. Forty (57.1%) participants had normal BMI while 30 (42.9%) participants had BMI ≥ 25 kg/m² (P0 = 0.053). The mean BC level was lower in participants with BMI ≥ 25 kg/m² but not significant. There was a negative correlation between BMI and BC level ( r = -0.205, P = 0.88) while a positive correlation existed between stimulated cortisol level and BMI (r = 0.009, P = 0.944). Persons with BMI above 25 kg/m² had lower BC level though not statistically significant, the trend was noticed. Subjecting people whose BMI is above 25 kg/m² to further stimulation with ACTH because of low BC is not advised because their response to ACTH stimulation was similar to those who have normal BMI.

    Full Text Available Objective: Although the diagnosis of patients with severemalnutrition is easy, it is very difficult to recognize patientswith mild and moderate malnutrition. A variety of methodsattempts to develop for early diagnosis of these cases.In this study, we evaluated the serum transferrin and albuminlevels in children with mild, moderate and severeprotein-energy malnutrition (PEM.Materials and methods: Children admitted to our policlinic,aged between 3 and 25 months, 45 subjects withPEM and 39 healthy subjects (control group were evaluated.According to the Gomez, Waterlow and Kanawatisubjects with PEM were divided in 3 subgroups mild,moderate and severe PEM. Anthropometric measurementsand biochemical results of 4 groups were compared.Results: For albumin levels in mild to moderate PEMgroups, 37.7% sensitivity, and 28.5% specificity, positivepredictive value 54%; negative predictive value 16.6%was found. For severe PEM sensitivity, specificity, positivepredictive value and negative predictive value were71%, 62.5%, 45%, and 83.3% respectively.With respect to the levels of transferrin, a significant differencewas found between mild PEM-control and moderatePEM-control groups (p0.05.Conclusion: Our study results showed that albumin isa weak indicator in mild-moderate PEM. In these cases,serum transferrin level reduces before decreasing of albuminlevel, thus it may be an early sensitive finding thatcan be used as a sensitive parameter in the diagnosis ofearly stages of malnutrition.Key words: Protein energy malnutrition, children, albumin,transferrin

    The serum gastrin level (SGL) is studied in dynamics during each lunar month of pregnancy in order to accumulate data which may serve the purpose of a tentative standard for serum gastrin level in this peculiar physiologic condition. A group of 110 pregnant women with a normal development of pregnancy, as documented by the clinical and paraclinical examination, are covered by the study. Blood samples are taken before meal, and a radioimmunologic method is used for SGL assessment. The number of women analyzed and the mean age by lunar months are shown. The normal value established in nonpregnant women of the same age group is 28+-7 mg/ml, relative to which the average values during the first five i.m. do not show statistically significant differences. During the 6th l.m. SGL increases to 68.5 mg/ml, while after the 7th l.m. values are recorded exceeding 1aa mg/ml with a maximum observed in the 8th and 9th l.m. The mechanisms eventually involved in the occurrence of gastrinemia during the second half of pregnancy are discussed, e.g. 1/mechanical compression of the stomach by the progressively growing uterus, 2/decreased breakdown, inhibition and elimimation of the hormone by the kidneys, and 3/possible correlative dependence between changes in SGL and changes in the level of hormones playing a predominant role in the hormonal status after the fifth month of pregnancy.

    The objective of the current study was to determine the relationship between serum vitamin D levels and the severity of atopic dermatitis (AD) in a Brazilian population. This was a cross-sectional study of patients younger than 14 years of age seen from April to November 2013. All patients fulfilled the Hanifin and Rajka Diagnostic Criteria for AD diagnosis. Disease severity was determined using the SCORing Atopic Dermatitis index and classified as mild (50). Serum vitamin D levels were classified as sufficient (≥30 ng/mL), insufficient (29-21 ng/mL), or deficient (≤20 ng/mL). A total of 105 patients met the inclusion criteria. Mild AD was diagnosed in 58 (55.2%) children, moderate in 24 (22.8%), and severe in 23 (21.9%). Vitamin D deficiency was observed in 45 individuals (42.9%). Of these, 24 (53.3%) had mild AD, 13 (28.9%) moderate, and 8 (17.7%) severe. Insufficient vitamin D levels were found in 45 (42.9%) individuals; 24 (53.3%) had mild AD, 9 (20.0%) moderate, and 12 (26.7%) severe. Of the 15 individuals (14.2%) with sufficient vitamin D levels, 10 (60.7%) had mild AD, 2 (13.3%) moderate, and 3 (20.0%) severe. The mean vitamin D level was 22.1 ± 7.3 ng/mL in individuals with mild AD, 20.8 ± 6.5 ng/mL in those with moderate AD, and 21.9 ± 9.3 ng/mL in those with severe AD. Variables such as sex, age, skin phototype, season of the year, and bacterial infection were not significantly associated with vitamin D levels. Levels of 25-hydroxyvitamin D were deficient or insufficient in 85% of the children, but serum vitamin D concentrations were not significantly related to AD severity. © 2016 Wiley Periodicals, Inc.

    It has been suggested that glucose levels ≥155 mg/dl at 1-h during an oral glucose tolerance test (OGTT) may predict development of type 2 diabetes and cardiovascular events among adults with normal glucose tolerance (NGT 1 h-high). Studies showed a link between increased blood viscosity and type 2 diabetes. However, whether blood viscosity is associated with dysglycemic conditions such as NGT 1 h-high, impaired glucose tolerance (IGT) or impaired fasting glucose (IFG) is unsettled. 1723 non-diabetic adults underwent biochemical evaluation and OGTT. A validated formula based on hematocrit and total plasma proteins was employed to estimate whole blood viscosity. Subjects were categorized into NGT with 1 h glucose h-low), NGT-1 h-high, IFG and/or IGT. Hematocrit and blood viscosity values appeared significantly higher in individuals with NGT 1 h-high, IFG and/or IGT as compared to NGT 1 h-low subjects. Blood viscosity was significantly correlated with age, waist circumference, blood pressure, HbA1c, fasting, 1- and 2-h post-challenge insulin levels, total cholesterol and low-density lipoprotein, triglycerides, fibrinogen, white blood cell, and inversely correlated with high-density lipoprotein and insulin sensitivity. Of the four glycemic parameters, 1-h post-challenge glucose showed the strongest correlation with blood viscosity (β = 0.158, P h post-challenge plasma glucose. They also suggest that a subgroup of NGT individuals with 1-h post-challenge plasma >155 mg/dl have increased blood viscosity comparable to that observed in subjects with IFG and/or IGT.

    Tributyltin (TBT), a toxic environmental contaminant, has been widely utilized for various industrial, agricultural and household purposes. Its usage has led to a global contamination and its bioaccumulation in aquatic organisms and terrestrial mammals. Previous studies suggest that TBT has debilitating effects on the overall immune function of animals, rendering them more vulnerable to diseases. TBT (at concentrations that have been detected in human blood) alters secretion of inflammatory cytokines from human lymphocytes ex vivo. Thus, it is important to determine if specified levels of TBT can alter levels of cytokines in an in vivo system. Mice were exposed to biologically relevant concentrations of TBT (200, 100 or 25 nM final concentrations). The quantitative determination of interferon (IFN)-γ, tumor necrosis factor (TNF)-α, interleukin (IL)-1β, IL2, IL5, IL7, IL12βp40, IL13, IL15, KC, MIP1β, MIP2 and RANTES was performed in mouse sera by MAGPIX analysis and Western blot. Results indicated alterations (both decreases and increases) in several cytokines. The pro-inflammatory cytokines IFNγ, TNFα, IL-1β, IL-2, IL5, IL12βp40, and IL-15 were altered as were the chemokines MIP-1 and RANTES and the anti-inflammatory cytokine IL-13. Increases in IFNγ and TNFα were seen in serum of mice exposed to TBT for less than 24 hr. IL1-β, IL-12βp40, IL-5 and IL-15 were also modulated in mouse serum depending on the specific experiment and the exposure concentration. IL-2 was consistently decreased in mouse serum when animals were exposed to TBT. There were also TBT-induced increases in MIP-1β, RANTES, and IL-13. These results from human and murine samples clearly suggest that TBT exposures modulate the secretion inflammatory cytokines. PMID:27602597

  8. Deconvolution of serum cortisol levels by using compressed sensing.

    Rose T Faghih

    Full Text Available The pulsatile release of cortisol from the adrenal glands is controlled by a hierarchical system that involves corticotropin releasing hormone (CRH from the hypothalamus, adrenocorticotropin hormone (ACTH from the pituitary, and cortisol from the adrenal glands. Determining the number, timing, and amplitude of the cortisol secretory events and recovering the infusion and clearance rates from serial measurements of serum cortisol levels is a challenging problem. Despite many years of work on this problem, a complete satisfactory solution has been elusive. We formulate this question as a non-convex optimization problem, and solve it using a coordinate descent algorithm that has a principled combination of (i compressed sensing for recovering the amplitude and timing of the secretory events, and (ii generalized cross validation for choosing the regularization parameter. Using only the observed serum cortisol levels, we model cortisol secretion from the adrenal glands using a second-order linear differential equation with pulsatile inputs that represent cortisol pulses released in response to pulses of ACTH. Using our algorithm and the assumption that the number of pulses is between 15 to 22 pulses over 24 hours, we successfully deconvolve both simulated datasets and actual 24-hr serum cortisol datasets sampled every 10 minutes from 10 healthy women. Assuming a one-minute resolution for the secretory events, we obtain physiologically plausible timings and amplitudes of each cortisol secretory event with R (2 above 0.92. Identification of the amplitude and timing of pulsatile hormone release allows (i quantifying of normal and abnormal secretion patterns towards the goal of understanding pathological neuroendocrine states, and (ii potentially designing optimal approaches for treating hormonal disorders.

The basic information, including age, sex, height, weight, waistline, hipline, menstrual cycle, and medical history, were collected by a questionnaire survey and physical examination. Serum lipid profiles, BG, postprandial blood glucose, and glycosylated hemoglobin were obtained after 12 hours fasting. BMD in lumbar spine was measured by dual-energy X-ray absorptiometry scanning.Results: The age-adjusted BMD in females was significantly lower than in males. With aging, greater differences of BMD distribution exist in elderly females than in males (P<0.001, and the fastigium of bone mass loss was in the age range from 51 to 55 in females and from 61 to 65 years in males. After adjustment for sex, there were significant differences in BMD among BMI-stratified groups in both males and females. The subjects with a BMI of <18.5 had a higher incidence of osteoporosis than BMI ≥18.5 in both sexes. BMD in type 2 diabetes mellitus with a BG of >7.0 mmol/L was lower than in people with BG of ≤7.0 mmol/L (P<0.001. People with serum high-density lipoprotein cholesterol levels of ≥1.56 mmol/L had a greater prevalence of osteoporosis compared with high-density lipoprotein cholesterol ≤1.55 mmol/L.

    Dietary therapy is an important treatment component for diabetes mellitus (DM). In this study, the impact of three different commercially available diet regiments (1 general use and 2 aimed for treating obesity and DM) on short-term post-prandial serum glucose and insulin concentrations of five healthy cats to better understand what impact each of these diets may have for diabetic cats. The diet regiments used in this study were as follows: C/D dry (General Use- Low protein, High fat, High carbohydrate, and Low fiber), M/D dry (DM- High protein, High fat, Low carbohydrate, and High Fiber), and W/D dry (DM- Low Protein, Low Fat, High Carbohydrate, and High Fiber). No significant difference in post-prandial serum glucose levels were observed with the C/D (84.6 +/- 1.5 mg/dl) and W/D (83.8 +/- 1.4 mg/dl) dry diets when compared to pre-prandial fasting levels (83.9 +/- 1.4 mg/dl). However, a significant reduction was observed with the M/D diet (78.9 +/- 0.8 mg/dl) which had 50-60% less carbohydrates than either C/D or W/D diet. Unlike what was observed with post-prandial glucose levels, an interesting pattern emerged with post-prandial insulin levels, which were increasing with W/D, C/D, and M/D diets in that order (1.1 +/- 0.2, 1.7 +/- 0.2, and 2.3 +/- 0.2 ng/ml respectively). Most surprising, though, was the fact that the W/D diet did not seem to stimulate insulin secretion as compared to pre-prandial levels (1.1 +/- 0.1 ng/ml) in healthy cats. Interestingly, the W/D diet had high levels of carbohydrate and low levels of protein. Coincidentally, the only diet (M/D) which had a significant reduction in post-prandial glucose also showed the highest increase in post-prandial insulin in healthy cats. Therefore, dietary amounts of carbohydrate, fat, protein and fiber can all have an individual impact on post-prandial glycemia and subsequent insulin requirement levels. Just as concepts regarding dietary management of people with DM are evolving, investigators are

  11. Blood Glucose Levels Following Intra-Articular Steroid Injections in Patients with Diabetes: A Systematic Review.

    Choudhry, M N; Malik, R A; Charalambous, Charalambos Panayiotou

    2016-03-22

    Parenterally administered steroids have been shown to affect the metabolism of glucose and to cause abnormal blood glucose levels in diabetic patients. These abnormal blood glucose levels in diabetic patients raise concerns that intra-articular steroid injections also may affect blood glucose levels. We performed a systematic review of studies examining the effect of intra-articular steroid injections on blood glucose levels in patients with diabetes mellitus. A literature search of the PubMed, EMBASE, AMED, and CINAHL databases using all relevant keywords and phrases revealed 532 manuscripts. After the application of inclusion criteria, seven studies with a total of seventy-two patients were analyzed. All studies showed a rise in blood glucose levels following intra-articular steroid injection. Four of the seven studies showed a substantial increase in blood glucose. Peak values reached as high as 500 mg/dL. The peak increase in blood glucose did not occur immediately following intra-articular steroid injection, and in some cases it took several days to occur. In many patients, post-injection hyperglycemia occurred within twenty-four to seventy-two hours. Intra-articular steroid injections may cause hyperglycemia in patients with diabetes mellitus, and patients should be warned of this complication. Diabetic patients should be advised to regularly monitor their blood glucose levels for up to a week after injection and should seek medical advice if safe thresholds are breached.

    Full Text Available The pulsed electric fields (PEF treatment is a novel method for obtaining glycated proteins by way of a Maillard reaction between proteins and polysaccharides but its effect on the preparation of protein–monosaccharide conjugate has not been explored. This study aimed to prepare bovine serum albumin (BSA–glucose and BSA–mannose conjugates using PEF in pH 10.0 at an intensity of 10 or 20 kV/cm, frequency of 1 kHz, pulse width of 20 μs and 73.5 pulses. The conjugates were evaluated for physicochemical properties. The results indicated that PEF not only promoted Maillard reaction between BSA and glucose or mannose but also alleviated the undesirable browning. PEF treatment favored the increased surface hydrophobicity and emulsifying activity in BSA but reduced surface hydrophobicity and foaming stability and improved foaming capacity in BSA–glucose and BSA–mannose conjugates. These findings provided useful considerations in the application of PEF treatment as a potential method to prepare BSA–monosaccharide conjugates by Maillard reaction.

    Screen-printed amperometric glucose biosensors have been fabricated using a water-based carbon ink. The enzyme glucose oxidase (GOD) and the electro-catalyst cobalt phthalocyanine were mixed with the carbon ink prior to the screen-printing process; therefore, biosensors are prepared in a one-step fabrication procedure. Optimisation of the biosensor performance was achieved by studying the effects of pH, buffer strength, and applied potential on the analytical response. Calibration studies were performed under optimum conditions, using amperometry in stirred solution, with an operating potential of +500 mV versus SCE. The sensitivity was found to be 1170 nA mM(-1), with a linear range of 0.025-2 mM; the former represents the detection limit. The disposable amperometric biosensor was evaluated by carrying out replicate determinations on a sample of bovine serum. This was achieved by the method of multiple standard additions and included a correction for background currents arising from oxidizable serum components. The mean serum concentration was calculated to be 8.63 mM and compared well with the supplier's value of 8.3 mM; the coefficient of variation was calculated to be 3.3% (n=6).

    2016-05-04

    DSP-4[N-(2-chloroethyl)-N-ethyl-2-bromobenzylamine hydrochloride] is a neurotoxin that depletes norepinephrine. The catecholaminergic system has been implicated in the regulation of blood glucose level. In the present study, the effect of DSP-4 administered intracerebroventricularly (i.c.v.) or intrathecally (i.t.) on blood glucose level was examined in d-glucose-fed and restraint stress mice models. Mice were pretreated once i.c.v. or i.t. with DSP-4 (10-40μg) for 3days, and d-glucose (2g/kg) was fed orally. Blood glucose level was measured 0 (prior to glucose feeding or restraint stress), 30, 60, and 120min after d-glucose feeding or restraint stress. The i.c.v. or i.t. pretreatment with DSP-4 attenuated blood glucose level in the d-glucose-fed model. Plasma corticosterone level was downregulated in the d-glucose-fed model, whereas plasma insulin level increased in the d-glucose-fed group. The i.c.v. or i.t. pretreatment with DSP-4 reversed the downregulation of plasma corticosterone induced by feeding d-glucose. In addition, the d-glucose-induced increase in plasma insulin was attenuated by the DSP-4 pretreatment. Furthermore, i.c.v. or i.t. pretreatment with DSP-4 reduced restraint stress-induced increases in blood glucose levels. Restraint stress increased plasma corticosterone and insulin levels. The i.c.v. pretreatment with DSP-4 attenuated restraint stress-induced plasma corticosterone and insulin levels. Our results suggest that depleting norepinephrine at the supraspinal and spinal levels appears to be responsible for downregulating blood glucose levels in both d-glucose-fed and restraint stress models.

    2017-09-01

    Full Text Available Introduction: This study aimed to investigate the relationship between serum adiponectin and metabolic syndrome in adults living in rural Malaysia. Methods: A total of 299 Malay adults (men=124; women = 175 with a mean age 48.8 (11.7 years were recruited. Measurements for waist circumference and blood pressure were taken before drawing an overnight fasting blood samples. Biochemical tests for triglycerides, HDL cholesterol, glucose and serum adiponectin concentration were measured. Results: Our results show that the adiponectin level in the subjects with metabolic syndrome was significantly lower than those without metabolic syndrome (p < 0.05. Among the metabolic syndrome risk factors, adiponectin level was significantly associated with hypertriglyceridemia and reduced HDL cholesterol (p < 0.001. Conclusion: The outcome from this study which highlights the association of hypoadiponectinemia with risk factors of metabolic syndrome in Malay adults, suggests that the reduced level of adiponectin may play a pivotal role in the development of metabolic syndrome in this ethnic group.

    2015-06-01

    Full Text Available Vitamin D deficiency (VDD is common in women with and without polycystic ovary syndrome (PCOS and may be associated with metabolic and endocrine disorders in PCOS. The aim of this meta-analysis is to assess the associations of serum vitamin D levels with metabolic and endocrine dysregulations in women with PCOS, and to determine effects of vitamin D supplementation on metabolic and hormonal functions in PCOS patients. The literature search was undertaken through five databases until 16 January 2015 for both observational and experimental studies concerning relationships between vitamin D and PCOS. A total of 366 citations were identified, of which 30 were selected (n = 3182. We found that lower serum vitamin D levels were related to metabolic and hormonal disorders in women with PCOS. Specifically, PCOS patients with VDD were more likely to have dysglycemia (e.g., increased levels of fasting glucose and homeostatic model assessment-insulin resistance index (HOMA-IR compared to those without VDD. This meta-analysis found no evidence that vitamin D supplementation reduced or mitigated metabolic and hormonal dysregulations in PCOS. VDD may be a comorbid manifestation of PCOS or a minor pathway in PCOS associated metabolic and hormonal dysregulation. Future prospective observational studies and randomized controlled trials with repeated VDD assessment and better characterization of PCOS disease severity at enrollment are needed to clarify whether VDD is a co-determinant of hormonal and metabolic dysregulations in PCOS, represents a consequence of hormonal and metabolic dysregulations in PCOS or both.

    2015-01-01

    Cognitive dysfunction due to higher blood glucose level has been reported previously. Genistein (GEN) is a phytoestrogen that we hypothesized might lead to improved memory, despite elevated blood glucose levels at the time of memory consolidation. To investigate this hypothesis, we compared the effects of orally administered GEN on the central nervous system in normal versus glucose-loaded adult male rats. A battery of behavioral assessments was carried out. In the MAZE test, which measured s...

    Harmayetty, Harmayetty; Krisnana, Ilya; Anisa, Faida

    2009-01-01

    Introduction: Type 2 diabetes mellitus is deficiency of insulin and caused by decreases of insulin receptor or bad quality of insulin. As a result, insulin hormone does not work effectively in blood glucose regulation. String bean juice contains thiamin and fiber may regulate blood glucose level. The aim of this study was to analyze the effect of string bean juice to decrease blood glucose level of patients with type 2 diabetes mellitus. Method: This study employed a quasy-experimental pre-po...

    2015-01-01

    measured by immunoassay, and potential determinants of the serum sortilin level were assessed by generalized linear models. Serum levels of brain-derived neurotrophic factor (BDNF) and vascular endothelial growth factor (VEGF) were measured in previous studies. We identified a significant increase of serum...... sortilin levels in depressed individuals compared with controls (P = 0.0002) and significant positive correlation between serum sortilin levels and the corresponding levels of BDNF and VEGF. None of the genotyped SNPs were associated with depression. Additional analyses showed that the serum sortilin level...... was influenced by several other factors. Alcohol intake and body mass index, as well as depression, serum BDNF and serum VEGF were identified as predictors of serum sortilin levels in our final multivariate model. In conclusion, the results suggest a role of circulating sortilin in depression which may relate...

    2010-07-01

    The objective of this study was to evaluate serum concentrations of nonesterified fatty acids, glucose, insulin, and progesterone in nonlactating dairy cows according to nutritional balance and glucose infusion. Ten nonlactating, ovariectomized Gir x Holstein cows were stratified by body weight (BW) and body condition score (BCS) on d -28 of the study, and randomly assigned to 1) negative nutrient balance (NB) or 2) positive nutrient balance (PB). From d -28 to d 0, cows were allocated according to nutritional treatment (5 cows/treatment) into 2 low-quality pastures with reduced forage availability. However, PB cows individually received, on average, 3 kg/cow per day (as-fed) of a concentrate during the study. All cows had an intravaginal progesterone releasing device inserted on d -14, which remained in cows until the end of the study. Cow BW and BCS were assessed again on d 0. On d 0, cows within nutritional treatment were randomly assigned to receive, in a crossover design containing 2 periods of 24h each, 1) intravenous glucose infusion (GLU; 0.5 g of glucose/kg of BW, as a 5% glucose solution administered, on average, at 32 mL/min over a 3-h period), or 2) intravenous saline infusion (SAL; 0.9% solution infused on average at 32 mL/min over a 3-h period). Prior to the beginning of each period, all cows were fasted for 12h. Blood samples were collected, relative to the beginning of the infusion, at -12 and -11.5h (beginning of fasting), and at -0.5, 0, 0.5, 1, 2, 3, 4, 5, and 6h. Following the last blood collection of period 1, cows received (PB) or not (NB) concentrate and were returned to their respective pastures. Changes in BCS and BW were greater in NB cows compared with PB cows (-0.60 and -0.25+/-0.090 for BCS, respectively; -22.4 and 1.2+/-6.58 kg for BW, respectively). Cows receiving GLUC had greater glucose concentrations from 0.5 to 3h relative to infusion compared with SAL cows. Insulin concentrations were greater in PB cows assigned to GLUC compared

    2017-01-01

    In early breast cancer patients, the effects of hormonal therapy (tamoxifen and aromatase inhibitors) on plasma fibroblast growth factor 21 (FGF-21), lipid levels and body composition have not yet been investigated. Therefore, we aimed to analyze the relationship between FGF-21 and body composition as well as the effects of tamoxifen and aromatase inhibitors on plasma lipid levels, FGF-21, and body composition. A total of 72 patients were treated with either tamoxifen or aromatase inhibitors due to their menopausal status after adjuvant radiotherapy. Each patient was followed-up over a period of 1 year. Changes in body composition and serum lipid profile, glucose and FGF-21 levels were evaluated. We recorded the type of hormonal therapy, body mass index, waist-to-hip ratio, lipid profile, and FGF-21 levels both at the beginning and after 12 months. There was a statistically significant decrease in serum FGF-21 levels after 12 months of adjuvant endocrine therapy (46 ± 19.21 pg/ml vs. 30.99 ± 13.81 pg/ml, pbody water (pbody composition, glucose, lipid profile and FGF-21 were similar in tamoxifen and aromatase inhibitor groups. A positive correlation was found between basal weight, fat mass, fat-free mass and serum FGF-21 levels; however, the correlation was maintained only for the fat-free mass at the 12th month. As part of the present study, we suggest that both tamoxifen and aromatase inhibitors can reduce FGF-21 levels independently of body compositions, and these drugs can provide antihyperlipidemic, antidiabetic and cardio-protective effects. We also recommend that serum FGF-21 level can be utilized as a tumor biomarker in early-stage breast cancer and for monitoring purposes. FGF-21 levels may help physicians estimate prognosis, too. Further studies with larger populations may shed light on the role of FGF-21 in breast cancer.

    Although the effects on prognosis of blood glucose level variability have gained increasing attention, it is unclear whether blood glucose level variability itself or the manifestation of pathological conditions that worsen prognosis. Then, previous reports have not been published on variability models of perioperative blood glucose levels. The aim of this study is to establish a novel variability model of blood glucose concentration using an artificial pancreas. We maintained six healthy, male beagles. After anesthesia induction, a 20-G venous catheter was inserted in the right femoral vein and an artificial pancreas (STG-22, Nikkiso Co. Ltd., Tokyo, Japan) was connected for continuous blood glucose monitoring and glucose management. After achieving muscle relaxation, total pancreatectomy was performed. After 1 h of stabilization, automatic blood glucose control was initiated using the artificial pancreas. Blood glucose level varied for 8 h, alternating between the target blood glucose values of 170 and 70 mg/dL. Eight hours later, the experiment was concluded. Total pancreatectomy was performed for 62 ± 13 min. Blood glucose swings were achieved 9.8 ± 2.3 times. The average blood glucose level was 128.1 ± 5.1 mg/dL with an SD of 44.6 ± 3.9 mg/dL. The potassium levels after stabilization and at the end of the experiment were 3.5 ± 0.3 and 3.1 ± 0.5 mmol/L, respectively. In conclusion, the results of the present study demonstrated that an artificial pancreas contributed to the establishment of a novel variability model of blood glucose levels in beagles.

    To establish the parsimonious model for blood glucose monitoring in patients with type 2 diabetes receiving oral hypoglycemic agent treatment. One hundred and fifty-nine adult Chinese type 2 diabetes patients were randomized to receive rapid-acting or sustained-release gliclazide therapy for 12 weeks. Their blood glucose levels were measured at 10 time points in a 24 h period before and after treatment, and the 24 h mean blood glucose levels were measured. Contribution of blood glucose levels to the mean blood glucose level and HbA1c was assessed by multiple regression analysis. The correlation coefficients of blood glucose level measured at 10 time points to the daily MBG were 0.58-0.74 and 0.59-0.79, respectively, before and after treatment (Pblood glucose levels measured at 6 of the 10 time points could explain 95% and 97% of the changes in MBG before and after treatment. The three blood glucose levels, which were measured at fasting, 2 h after breakfast and before dinner, of the 10 time points could explain 84% and 86% of the changes in MBG before and after treatment, but could only explain 36% and 26% of the changes in HbA1c before and after treatment, and they had a poorer correlation with the HbA1c than with the 24 h MBG. The blood glucose levels measured at fasting, 2 h after breakfast and before dinner truly reflected the change 24 h blood glucose level, suggesting that they are appropriate for the self-monitoring of blood glucose levels in diabetes patients receiving oral anti-diabetes therapy.

    We aimed to assess the predictive value of mean serum uric acid (SUA) levels for incident prediabetes. Normoglycemic adults (n=39,353) were followed for a median of 3.0years. Prediabetes is defined as impaired fasting glucose (IFG), impaired glucose tolerance (IGT), or impaired HbA1c (IA1c), based on the American Diabetes Association criteria. Serum SUA levels were measured annually. Four diagnostic strategies were used to detect prediabetes in four separate analyses (Analysis 1: IFG. Analysis 2: IFG+IGT. Analysis 3: IFG+IA1c. Analysis 4: IFG+IGT+IA1c). Cox proportional hazards regression models were used to assess the relationship between SUA quintiles and prediabetes. C-statistic was additionally used in the final analysis to assess the accuracy of predictions based upon baseline SUA and mean SUA, respectively. After adjustment for potential confounders, the hazard ratios (95% confidence interval) of prediabetes for the highest versus lowest quintile of mean SUA were 1.22 (1.10, 1.36) in analysis 1; 1.59 (1.23, 2.05) in analysis 2; 1.62 (1.34, 1.95) in analysis 3 and 1.67 (1.31, 2.13) in analysis 4. In contrast, for baseline SUA, significance was only reached in analyses 3 and 4. Moreover, compared with baseline SUA, mean SUA value was associated with a significant increase in the C-statistic (Pprediabetes risk, and showed better predictive ability for prediabetes than baseline SUA.

  15. Glucose and phosphate modulation of intracellular 45Ca incorporated into pancreatic islets during culture in the absence and presence of serum

    Bergsten, P.

    1985-01-01

    The effects of glucose and phosphate on the intracellular 45 Ca content were measured in β cell-rich pancreatic islets cultured in media containing or lacking serum. Irrespective of the glucose and serum concentrations there were no or very small increments of 45 Ca contents when phosphate was raised from 0.8 to 5.8 mM during culture for 1 day. However, after 7 days of culture in serum-free medium there was a massive accumulation of 45 Ca in the islets in response to the higher phosphate concentration. Glucose markedly reduced, and serum eliminated, the extensive accumulation probably due to increased cell viability. In the cells cultured in the presence of serum, raising the glucose concentration from 1.0 to 5.5 mM resulted in an increased incorporation of 45 Ca. This effect was particularly pronounced after culture for 7 days in 5.8 mM phosphate. A further increase of glucose to 20 mM reduced the 45 Ca content. The results are consistent with the concept that glucose both stimulates 45 Ca uptake into different β-cell pools and degranulates the cell with associated loss of intracellular calcium from the granular calcium pool.

    2012-01-01

    Full Text Available Background and Objectives: Low birth weight (LBW is a major public health problem. LBW is associated with increased neonatal morbidity and mortality. There is no consensus in the literature as to whether maternal copper nutrition is associated with pregnancy outcome or fetal growth. Methods: This case-control study was carried out at Alavi Hospital in Ardabil between August 2008 and August 2009. 56 women who had delivered low-birth- weight infants (<2500gr were taken as the case group, and from the mothers who had delivered normal birth weight infants (≥2500gr, 56 were selected at random as the control group. Venous blood samples were obtained from the mothers. Serum zinc level was determined by the Atomic Absorption Spectrophotometer method.Results: Mean of birth weight in infants, maternal age, body mass index in mothers and socioeconomic or demographic factors did not differ between cases and control groups. Maternal copper concentration (μg/dl differed between Cases and Controls; 231.75±38.12μg/dl vs. 204.42±31.30μg/dl respectively. There is a significant difference (p<0.001 in the serum copper concentration between the two groups.Conclusion: There is a negative relation between low infant birth weight and maternal copper concentration.

    Full Text Available Abstract Background Aspirin esterase (AE activity can account for part of aspirin pharmacokinetics in the circulation, possibly being associated with the impairment of aspirin effectiveness as an inhibitor of platelet aggregation. Aims The study was aimed at investigating the correlations of serum AE activity with cholinesterase (ChE and metabolic variables in healthy subjects in comparison to subjects with type 2 diabetes mellitus (T2DM. Methods In cardiovascular disease-free T2DM subjects and healthy controls, the AE activity levels and/or the correlation patterns between AE and the other variables were analyzed. Results Neither AE nor ChE activities were higher in the subjects with T2DM. Serum AE activity strongly correlated with ChE as well as glucose/lipids variables such as total cholesterol and triglyceride in healthy subjects, while the correlations between AE and glucose/lipids variables were not present in T2DM subjects. Conclusions These data may reflect the pathophysiological changes between healthy and T2DM subjects. Our data may thus provide the basis for future studies to unravel the mechanisms.

    Adiponectin regulates glucose and lipid metabolism, acting against metabolic syndrome and atherosclerosis. Accumulating evidence suggest that adiponectin acts on the brain including hypothalamic arcuate nucleus (ARC), where proopiomelanocortin (POMC) neurons play key roles in feeding regulation. Several studies have examined intracerebroventricular (ICV) injection of adiponectin and reported opposite effects, increase or decrease of food intake. These reports used different nutritional states. The present study aimed to clarify whether adiponectin exerts distinct effects on food intake and ARC POMC neurons depending on the glucose concentration. Adiponectin was ICV injected with or without glucose for feeding experiments and administered to ARC slices with high or low glucose for patch clamp experiments. We found that adiponectin at high glucose inhibited POMC neurons and increased food intake while at low glucose it exerted opposite effects. The results demonstrate that glucose level determines excitatory or inhibitory effects of adiponectin on arcuate POMC neuron activity and feeding.

    Altered progranulin levels play a major role in neurodegenerative diseases, like Alzheimer's dementia (AD), frontotemporal dementia (FTD) and amyotrophic lateral sclerosis (ALS), even in the absence of GRN mutations. Increasing progranulin levels could hereby provide a novel treatment strategy. However, knowledge on progranulin regulation in neurodegenerative diseases remains limited. We here demonstrate that cerebrospinal fluid progranulin levels do not correlate with its serum levels in AD, FTD and ALS, indicating a differential regulation of its central and peripheral levels in neurodegeneration. Blood progranulin levels thus do not reliably predict central nervous progranulin levels and their response to future progranulin-increasing therapeutics.

    2011-01-01

    Cardiovascular diseases (CVD) are the leading cause of morbidity, mortality and disability worldwide. Leptin, a 16kDa product of ob gene, is an endocrine hormone produced by white adipose tissue. It is primarily involved in the regulation of food intake and energy expenditure. Hyperleptinemia is one of the novel risk factors contributing in many ways to CVD. Objective: The objective of the study was to find the level of leptin in patients with coronary artery disease (CAD) and compare it with healthy people in our population. Methods: Our study was an analytical and cross-sectional study. Our study included 60 patients with a history of CAD and 60 healthy controls (aged 40-60 years, both sexes). Leptin levels were measured by ELISA. Results: Mean serum leptin level in patients was 11.48+-11.25 g/ml, while control group had a mean leptin level of 8.22+-8.01 g/ml (p=0.071). Conclusion: Leptin levels were higher in patients but the difference was non-significant. More studies are needed with larger sample size in our population. (author)

  3. Progranulin serum levels in human kidney transplant recipients: A longitudinal study.

    Bruna Bellincanta Nicoletto

    Full Text Available The adipokine progranulin has metabolic proprieties, playing a role in obesity and insulin resistance. Its levels seems to be dependent of renal function, since higher progranulin concentration is observed in patients with end-stage kidney disease. However, the effect of kidney transplantation on progranulin remains unknown.To assess the serum progranulin levels in kidney transplant recipients before and after kidney transplantation.Forty-six prospective kidney transplant recipients were included in this longitudinal study. They were evaluated before transplantation and at three and twelve months after transplantation. Clinical, anthropometric and laboratorial measurements were assessed. Progranulin was determined with enzyme-linked immunosorbent assays.Serum progranulin significantly decreased in the early period after transplantation (from 72.78 ± 2.86 ng/mL before transplantation to 40.65 ± 1.49 ng/mL at three months; p<0.01 and increased at one year (53.15 ± 2.55 ng/mL; p<0.01 vs. three months, remaining significantly lower than before transplantation (p<0.01 (pover time<0.01. At one year after transplantation, there was a significant increase in body mass index, trunk fat and waist circumference compared to immediate period after transplantation. Progranulin was associated with waist circumference and fasting plasma glucose after adjusted for age, gender, study period, glomerular filtration rate, interleukin-6, high sensitivity C reactive protein and adiponectin.Progranulin serum levels are increased before transplantation and a reduction is observed in the early period after transplantation, possibly attributed to an improvement in renal function. At one year after transplantation, an increment in progranulin is observed, seems to be independent of glomerular filtration, and remained significantly lower than before transplantation.

  4. Association between serum irisin levels and non-alcoholic fatty liver disease in health screen examinees.

    Eun Sung Choi

    Full Text Available Irisin is a recently found myokine that aids obesity control and improves glucose homeostasis by acting on white adipose tissue cells and increases total energy consumption. The aim of this study was to evaluate serum irisin levels in patients with non-alcoholic fatty liver disease (NAFLD and to compare these levels with those of normal controls. Among 595 health screen examinees who had visited our institute between January 2013 to March 2013, 355 patients (84 NAFLD patients and 271 normal controls were enrolled depending on whether they gave written informed consents and their history of alcohol intake, blood tests, and abdominal ultrasonographic findings. Age; sex; laboratory test parameters; homeostasis model assessment-insulin resistance; and levels of leptin, adiponectin, and irisin were assessed. Serum irisin levels (ng/ml were significantly higher in the NAFLD group than in normal controls (63.4 ± 32.6 vs. 43.0 ± 29.7, p<0.001 and higher in the mild fatty liver group than in the moderate-to-severe fatty liver group (68.3 ± 38.2 vs. 56.6 ± 21.2, p<0.001. Additionally, serum irisin levels were not different between the non-obese and obese groups (48.4 ± 34.2 vs. 45.8 ± 22.9, p = 0.492; however, the levels were significantly lowest in normal controls and highest in the mild fatty liver group in the non-obese (44.9 ± 31.7 vs. 73.1 ± 48.5 vs 59.7 ± 18.0, p<0.001 and obese groups (35.0 ± 17.0 vs. 62.9 ± 21.2 vs. 54.6 ± 23.3, p<0.001. Serum irisin levels were significantly higher in NAFLD patients, which is not consistent with the results of previously published studies. Therefore, more studies are needed to confirm the role of irisin in NAFLD.

  5. Lack of effect of dietary fiber on serum lipids, glucose, and insulin in healthy young men fed high starch diets.

    Ullrich, I H; Albrink, M J

    1982-07-01

    Eight healthy young men were fed a 72% carbohydrate high starch diet either high or low in dietary fiber for 4 days in a double cross-over design. Both groups showed a slight transient increase in plasma triglyceride level and a decrease in total and high-density lipoprotein cholesterol. There were few differences in glucose and insulin levels after glucose and meal tolerance tests after each diet. Fasting triglycerides and high-density lipoprotein cholesterol were inversely related at base-line; insulin response to oral glucose was inversely related to high-density lipoprotein cholesterol levels at the end of the study. We conclude that a high carbohydrate high starch diet, whether high or low in fiber, caused little increase in triglycerides, with little difference between the high and low fiber diets. Dietary fiber did not influence the fall in plasma cholesterol or high-density lipoprotein cholesterol concentrations over and above that seen after the low fiber diet.

    2014-08-01

    Alpha-melanocyte stimulating hormone (α-MSH) is known as a regulator of the blood glucose homeostasis and food intake. In the present study, the possible roles of α-MSH located in the spinal cord in the regulation of the blood glucose level were investigated in d-glucose-fed and immobilization stress (IMO) mouse models. We found in the present study that intrathecal (i.t.) injection with α-MSH alone did not affect the blood glucose level. However, i.t. administration with α-MSH reduced the blood glucose level in d-glucose-fed model. The plasma insulin level was increased in d-glucose-fed model and was further increased by α-MSH, whereas α-MSH did not affect plasma corticosterone level in d-glucose-fed model. In addition, i.t. administration with glucagon alone enhanced blood glucose level and, i.t. injection with glucagon also increased the blood glucose level in d-glucose-fed model. In contrasted to results observed in d-glucose-fed model, i.t. treatment with α-MSH caused enhancement of the blood glucose level in IMO model. The plasma insulin level was increased in IMO model. The increased plasma insulin level by IMO was reduced by i.t. treatment with α-MSH, whereas i.t. pretreatment with α-MSH did not affect plasma corticosterone level in IMO model. Taken together, although spinally located α-MSH itself does not alter the blood glucose level, our results suggest that the activation of α-MSH system located in the spinal cord play important modulatory roles for the reduction of the blood glucose level in d-glucose fed model whereas α-MSH is responsible for the up-regulation of the blood glucose level in IMO model. The enhancement of insulin release may be responsible for modulatory action of α-MSH in down-regulation of the blood glucose in d-glucose fed model whereas reduction of insulin release may be responsible for modulatory action of α-MSH in up-regulation of the blood glucose in IMO model.

    2016-10-01

    Considering traditional use of Tribulus terrestris in diabetes and proven antihyperglycemic and antihyperlipidemic effects of T terrestris in animal studies, we aimed to evaluate the efficacy of the hydroalcoholic extract of T terrestris on the serum glucose and lipid profile of women with non-insulin-dependent diabetes mellitus. Ninety-eight women with diabetes mellitus type 2 were randomly allocated to receive the T terrestris (1000 mg/d) or placebo for 3 months. The patients were evaluated in terms of the fasting blood glucose, 2-hour postprandial glucose, glycosylated hemoglobin, and lipid profile. Tribulus terrestris showed a significant blood glucose-lowering effect in diabetic women compared to placebo (P terrestris group was significantly reduced compared with placebo, while no significant effect was observed in the triglyceride and high-density lipoprotein levels. The study showed preliminary promising hypoglycemic effect of T terrestris in women with diabetes mellitus type 2. © The Author(s) 2016.

  8. The Importance of Serum Cytokine Levels in Febrile Neutropenia

    Nuray Buyukberber

    2003-02-01

    Full Text Available The most important evaluation of the neutropenic patients is to determine the risk group. The desired approach to patients with low risks should be either not to hospitalize or to hospitalize for a short period of time which both decreases the cost and exposure to the resistant flora. The early diagnosis of sepsis in patients with high risk may be life saving. Recently, the determination of low and high-risk groups only by the clinical variables is not found to be a reliable method. The laboratory parameters supported by the clinical variables may be more practical. The determination of serum cytokines levels in febrile neutropenia may be helpful for the early risk diagnosis, new treatment approaches, and prognosis.

    2018-07-01

    A nonenzymatic glucose electrochemical sensor was constructed based on Au nanoparticles (AuNPs) decorated Ni metal-organic-framework (MOF)/Ni/NiO nanocomposite. Ni-MOF/Ni/NiO nanocomposite was synthesized by one-step calcination of Ni-MOF. Then AuNPs were loaded onto the Ni-based nanocomposites' surface through electrostatic adsorption. Through characterization by transmission electron microscopy (TEM), high resolution TEM (HRTEM) and energy disperse spectroscopy (EDS) mapping, it is found that the AuNPs were well distributed on the surface of Ni-based nanocomposite. Cyclic voltammetric (CV) study showed the electrocatalytic activity of Au-Ni nanocomposite was highly improved after loading AuNPs onto it. Amperometric study demonstrated that the Au-Ni nanocomposites modified glassy carbon electrode (GCE) exhibited a high sensitivity of 2133.5 mA M -1 cm -2 and a wide linear range (0.4-900 μM) toward the oxidation of glucose with a detection limit as low as 0.1 μM. Moreover, the reproducibility, selectivity and stability of the sensor all exhibited outstanding performance. We applied the as-fabricated high performance sensor to measure the glucose levels in human serum and obtained satisfactory results. It is believed that AuNPs decorated Ni MOF/Ni/NiO nanocomposite provides a new platform for developing highly performance electrochemical sensors in practical applications.

    Benign paroxysmal positional vertigo (BPPV) is a frequently encountered condition that can severely affect the quality of life. In this study, we aimed to assess the possible relations between serum uric acid (SUA) levels and BPPV. Fifty patients with BPPV, and 40 age- and sex-matched control subjects were enrolled in the study. All the patients and controls underwent a complete audio-vestibular test battery including the Dix-Hallpike maneuver and supine roll test for posterior semicircular canal (PSC) and horizontal semicircular canal, respectively. Routine hematological and biochemical analyses were performed in both groups. In the BPPV group, measurements of SUA levels were repeated 1 month after the vertigo attack. The lipid profiles and SUA levels were higher in patients with BPPV than detected in controls (P multiple logistic regression models (P decrement in SUA level 1 month after the vertigo attack compared with the values obtained during the attack (P 0.05). Elevated SUA is positively correlated with BPPV, requiring further efforts to clarify the exact mechanism. © 2013 The Author(s) European Journal of Neurology © 2013 EFNS.

  11. Serum lipid levels in pregnancies complicated by preeclampsia

    Valmir Jose de Lima

    Full Text Available CONTEXT AND OBJECTIVE: Pre-eclampsia is a disorder that occurs only during pregnancy. Postpartum changes relating to lipid metabolism may contribute towards the endothelial lesions observed in preeclampsia. Thus, the aim of the present study was to evaluate the lipid profile among patients who present preeclampsia and correlate these parameters with 24-hour proteinuria. DESIGN AND SETTING: Cross-sectional analytical study including 77 pregnant patients seen at Hospital Dório Silva. METHODS: This study involved 42 women with preeclampsia and 35 healthy pregnant women in the third trimester of pregnancy as controls. Blood samples were obtained from all the patients, and the serum levels of triglycerides, total cholesterol, low-density lipoproteins (LDL, high-density lipoproteins (HDL and very low density lipoproteins (VLDL were determined. Cases and controls were matched for maternal age, gestational week and body mass index. RESULTS: The VLDL and triglyceride values from the women with preeclampsia were significantly higher than those of the healthy women. There was a positive correlation between increased proteinuria and higher VLDL and triglyceride levels in patients with preeclampsia. CONCLUSION: Among the patients with preeclampsia, higher VLDL and triglyceride levels were positively correlated with proteinuria. These observations indicate that the pregnant women who presented elevated lipid levels were more susceptible to cardiovascular disorders and, consequently, pre-eclampsia.

    Full Text Available Background and aims: We designed this study to assess the effect of Ramadan fasting on serum lipid profile among type 2 diabetic patients. Material and Methods: The study was carried out in July 2014 (Ramadan 1421. The total duration of fasting was 17 hours a day. The investigation involved 80 patients. The mean age of the patients was 56± 8 years. The dietary survey lasting three days was recorded. The anthropometric and the biochemical parameters were measured in all subjects before (T1 and during (T2 the fasting month of Ramadan and results were compared using student t-test. Results: There was a significant decrease in high density lipoprotein cholesterol (HDL-c levels during T2 (0.35±0,08 g/L compared to T1 (0.38±0,11 g/L. Apolipoprotein A1 (Apo A1 decreased significantly during fasting compared to pre-fasting days while apo B increased during T2 (p˂0.05. The dietary fat consumption increased during Ramadan; especially for the saturated one (p<0.05. Conclusion: The present study suggests that fasting month of Ramadan could be beneficial for some patients with type 2 diabetes who are well controlled and balanced. However, some of them may be at risk of cardiovascular complications in which dyslipidemia can be the leading cause.

    König, Daniel; Kookhan, Sadaf; Schaffner, Denise; Deibert, Peter; Berg, Aloys

    2014-01-01

    The aim of this study was to investigate the effect of a 6-wk intervention with either lifestyle intervention (increased physical activity and a low-calorie diet) or a meal replacement regimen on glycemic control in patients who are prediabetic and have impaired fasting glucose. Forty-two overweight or obese men and women (age 54 ± 8 y; weight 95.1 ± 11.9 kg; body mass index [BMI] 32.8 ± 2.89 kg/m(2)) were included in this randomized controlled clinical trial. Patients in the lifestyle group (LS; n = 14) received dietary counseling sessions (fat-restricted low-calorie diet) and instructions on how to increase physical activity. Patients in the meal replacement group (MR; n = 28) were instructed to replace two daily meals with a low-calorie, high soy-protein drink with a low glycemic index. Both interventions resulted in a significant decrease in body weight and BMI, although the reduction was more pronounced (P meal replacement is an effective intervention for rapid improvement of elevated fasting glucose and increased insulin concentrations, these being important biomarkers of the prediabetic state. The 6-wk intervention has shown that the effect of meal replacement on fasting blood glucose was comparable to the effect of lifestyle intervention. The alterations in BMI, insulin, and HOMA-IR were significantly more pronounced following the meal replacement regimen. Copyright © 2014 Elsevier Inc. All rights reserved.

  14. The Effects of Blood Glucose Levels on Cognitive Performance: A Review of the Literature

    Feldman, Jolene; Barshi, Immanuel

    2007-01-01

    The purpose of this review paper is to discuss the research literature on the effects of blood glucose levels on executive and non-executive functions in humans. The review begins with a brief description of blood glucose, how it has been studied, previous syntheses of prior studies, and basic results regarding the role of blood glucose on cognitive functioning. The following sections describe work that investigated the effect of blood glucose on both non-executive and executive functions (e.g., sensory processing, psychomotor functioning, attention, vigilance, memory, language and communication, judgement and decision-making, and complex task performance). Within each section, summaries of the findings and challenges to the literature are included. Measurement conversions of blood glucose levels, blood glucose values, and associated symptoms are depicted. References to the types of tests used to investigate blood glucose and cognitive performance are provided. For more detailed descriptions of references within (and in addition to) this paper, an annotated bibliography is also provided. Several moderator variables including individual differences and contextual variables related to the effects of blood glucose levels on performance (e.g., age, gender, time of day, familiarity with the task and symptom awareness, expectancy effects, dose dependent effects, time dependent effects, task specific effects, rising and falling blood glucose levels, and speed and/or accuracy trade-offs) are addressed later in the paper. Some suggestions for future experimental methodologies are also made.

    The effect of Oxytocin on energy metabolism is still question. The aim of the present study was to investigate the effect of exogenous oxytocin injection in different dose and timetable on blood glucose level in rat. In this study 16 adult female rats were divided into 2 groups (Treatment 1(T1) and Treatment 2(T2)). T1 with 8 adult female rats received 0.2 IU/Kg oxytocin via intrapleural (IP) and blood glucose level was tested at 0th, 20th, 40th and 60th min after injection by collecting the blood from jugular vein. In T2 eight female rats received 0.4 IU/kg oxytocin via IP taking blood glucose measure at the same minutes as T1. The experiment tested in three replicates. Blood glucose meter (Model: 3TMSO1G) was used with glucose smart blood glucose monitoring system to the measurement of blood glucose level in rats. Data were analyzed using the GLM procedure of SAS (SAS, version 9) PDIFF was used to compare least square means among treatments adjusting by tukey test. There were hypoglycemic tendency in the changes of the blood glucose level in both T1 and T2, 20th min after injection (88.79 ± 3.28, 68.58 ± 3.63, respectively), while in the remaining subjects (4th and 60th min) blood glucose level increased (115.54 ± 4, 79.7 ± 2.09 and 136.33 ± 5.8, 123.54 ± 0.9, respectively). These results showed that blood glucose level in T1 significantly higher than T2 (p blood glucose level very fast.

    2007-07-27

    The aim of this clinical study was to determine whether there is a relationship between total serum testosterone, free testosterone, FSH (Follicle-Stimulating Hormone), LH (Luteinizing Hormone) and serum prostate specific antigen (PSA) levels. We postulated that such a correlation existed then the use of hormone specific reference ranges might enhance the usefullness of PSA concentrations 40 years of age visiting our urology outpatient clinics. PSA was correlated to age (r = 0.23, p = 0.019), but there none between serum testosterone and age. No significant correlation was noted between testosterone or free testosterone and serum PSA levels, and none between serum FSH or LH and PSA. In age specific reference groups (41-49; 50-59; 60-69 years), we found no significant correlation between PSA and hormone concentrations. In this population of eugonadal men with serum PSA values less than 2.5 ng/ml, serum androgens and pituitary hormones do not appear to correlate with serum PSA.

  18. Effects of chicory inulin on serum metabolites of uric acid, lipids, glucose, and abdominal fat deposition in quails induced by purine-rich diets.

    Lin, Zhijian; Zhang, Bing; Liu, Xiaoqing; Jin, Rui; Zhu, Wenjing

    2014-11-01

    Inulin, a group of dietary fibers, is reported to improve the metabolic disorders. In the present study, we investigated the effects of chicory inulin on serum metabolites of uric acid (UA), lipids, glucose, and abdominal fat deposition in quail model induced by a purine-rich diet. In this study, 60 male French quails were randomly allocated to five groups: CON (control group), MOD (model group), BEN (benzbromarone-treated group), CHI-H (high-dosage chicory inulin-treated group), and CHI-L (low-dosage chicory inulin-treated group). The serum UA level was significantly increased in the model group from days 7 to 28, as well as triglyceride (TG) and free fatty acid (FFA) increased later in the experimental period. The abdominal fat ratio was increased on day 28. Benzbromarone can decrease UA levels on days 14 and 28. The high and low dosage of chicory inulin also decreased serum UA levels on days 7, 14, and 28. The abdominal fat ratio, activity, and protein of acetyl-CoA carboxylase (ACC) were decreased in chicory inulin-treated groups. The activities of xanthine oxidase (XOD) and fatty acid synthase (FAS) were increased in the model group and decreased in the benzbromarone and chicory inulin groups. This study evaluated a quail model of induced hyperuricemia with other metabolic disorders caused by a high-purine diet. The results indicated that a purine-rich diet might contribute to the development of hyperuricemia, hypertriglyceridemia, and abdominal obesity. Chicory inulin decreased serum UA, TG, and abdominal fat deposition in a quail model of hyperuricemia by altering the ACC protein expression and FAS and XOD activities.

    Pregnancy is related to change in glucose metabolism and insulin production. The aim of our study was to determine the association of serum IFN-γ and TGF- β levels with insulin resistance during normal pregnancy. This cross sectional study was carried out on 97 healthy pregnant (in different trimesters) and 28 healthy non-pregnant women. Serum TGF-β and IFN- γ level were measured by ELISA method. Pregnant women had high level TGF-β and low level IFN-γ as compared non-pregnant women. Maternal serum TGF-β concentration significantly increased in third trimester as compared first and second trimester of pregnancy. Maternal serum IFN-γ concentration significantly decreased in third trimester as compared first and second trimester of pregnancy. Pregnant women exhibited higher score of HOMA IR as compared non-pregnant women. There were association between gestational age with body mass index (r=0.28, P=0.005), TGF-β (r=0.45, PInsulin resistance and TGF-β (r=0.17, p=0.05). Our findings suggest that changes in maternal cytokine level in healthy pregnant women were anti-inflammatory. Furthermore, Tumor Growth Factor-β appears has a role in induction insulin resistance in healthy pregnant women. However, further studies needed to evaluate role of different cytokines on insulin resistance in normal pregnancy.

    The possible roles of spinal histamine receptors in the regulation of the blood glucose level were studied in ICR mice. Mice were intrathecally (i.t.) treated with histamine 1 (H1) receptor agonist (2-pyridylethylamine) or antagonist (cetirizine), histamine 2 (H2) receptor agonist (dimaprit) or antagonist (ranitidine), histamine 3 (H3) receptor agonist (α-methylhistamine) or antagonist (carcinine) and histamine 4 (H4) receptor agonist (VUF 8430) or antagonist (JNJ 7777120), and the blood glucose level was measured at 30, 60 and 120 min after i.t. administration. The i.t. injection with α-methylhistamine, but not carcinine slightly caused an elevation of the blood glucose level. In addition, histamine H1, H2, and H4 receptor agonists and antagonists did not affect the blood glucose level. In D-glucose-fed model, i.t. pretreatment with cetirizine enhanced the blood glucose level, whereas 2-pyridylethylamine did not affect. The i.t. pretreatment with dimaprit, but not ranitidine, enhanced the blood glucose level in D-glucose-fed model. In addition, α-methylhistamine, but not carcinine, slightly but significantly enhanced the blood glucose level D-glucose-fed model. Finally, i.t. pretreatment with JNJ 7777120, but not VUF 8430, slightly but significantly increased the blood glucose level. Although histamine receptors themselves located at the spinal cord do not exert any effect on the regulation of the blood glucose level, our results suggest that the activation of spinal histamine H2 receptors and the blockade of spinal histamine H1 or H3 receptors may play modulatory roles for up-regulation and down-regulation, respectively, of the blood glucose level in D-glucose fed model.

    The International Agency for Research on Cancer has classified diesel engine exhaust (DEE) as a human lung carcinogen. Given that inflammation is suspected to be an important underlying mechanism of lung carcinogenesis, we evaluated the relationship between DEE exposure and the inflammatory response using data from a cross-sectional molecular epidemiology study of 41 diesel engine testing workers and 46 unexposed controls. Repeated personal exposure measurements of PM 2.5 and other DEE constituents were taken for the diesel engine testing workers before blood collection. Serum levels of six inflammatory biomarkers including interleukin (IL)-1, IL-6, IL-8, tumor necrosis factor (TNF)-α, macrophage inflammatory protein (MIP)-1β, and monocyte chemotactic protein (MCP)-1 were analyzed in all subjects. Compared to unexposed controls, concentrations of MIP-1β were significantly reduced by ∼37% in DEE exposed workers (P 397 µg/m 3 ) compared to unexposed controls. Further, significant inverse exposure-response relationships for IL-8 and MCP-1 were also found in relation to increasing PM 2.5 levels among the DEE exposed workers. Given that IL-8, MIP-1β, and MCP-1 are chemokines that play important roles in recruitment of immunocompetent cells for immune defense and tumor cell clearance, the observed lower levels of these markers with increasing PM 2.5 exposure may provide insight into the mechanism by which DEE promotes lung cancer.

    Many patients with polycystic ovary syndrome (PCOS) have insulin resistance, obesity (mostly visceral) and glucose intolerance, conditions associated with abnormalities in the production of vaspin, a novel adipokine that appears to preserve insulin sensitivity and glucose tolerance. The aim of the study was to assess serum vaspin levels in PCOS and the effects on vaspin levels of metformin or of weight loss. We studied 79 patients with PCOS and 50 healthy female volunteers. Normal weight patients with PCOS (n=25) were treated with metformin 850 mg bid for 6 months. Overweight/obese patients with PCOS (n=54) were prescribed a normal-protein, energy-restricted diet for 6 months; half of them were also given orlistat 120 mg tid and the rest were given sibutramine 10 mg qd. At baseline and after 6 months, serum vaspin levels and anthropometric, metabolic and hormonal features of PCOS were determined. Overall, patients with PCOS had higher vaspin levels than controls (p=0.021). Normal weight patients with PCOS had higher vaspin levels than normal weight controls (p=0.043). Vaspin levels were non-significantly higher in overweight/obese patients with PCOS than in overweight/obese controls. In normal weight patients with PCOS, metformin reduced vaspin levels non-significantly. In overweight/obese patients with PCOS, diet plus orlistat or sibutramine did not affect vaspin levels. Vaspin levels were independently correlated with body mass index in women with PCOS (p=0.001) and with waist circumference in controls (p=0.015). In conclusion, serum vaspin levels are elevated in PCOS but neither a small weight loss nor metformin affect vaspin levels significantly.

    According to the hypothesis of Traub, also known as the 'formula of Traub', postmortem values of glucose and lactate found in the cerebrospinal fluid or vitreous humor are considered indicators of antemortem blood glucose levels. However, because the lactate concentration increases in the vitreous and cerebrospinal fluid after death, some authors postulated that using the sum value to estimate antemortem blood glucose levels could lead to an overestimation of the cases of glucose metabolic disorders with fatal outcomes, such as diabetic ketoacidosis. The aim of our study, performed on 470 consecutive forensic cases, was to ascertain the advantages of the sum value to estimate antemortem blood glucose concentrations and, consequently, to rule out fatal diabetic ketoacidosis as the cause of death. Other biochemical parameters, such as blood 3-beta-hydroxybutyrate, acetoacetate, acetone, glycated haemoglobin and urine glucose levels, were also determined. In addition, postmortem native CT scan, autopsy, histology, neuropathology and toxicology were performed to confirm diabetic ketoacidosis as the cause of death. According to our results, the sum value does not add any further information for the estimation of antemortem blood glucose concentration. The vitreous glucose concentration appears to be the most reliable marker to estimate antemortem hyperglycaemia and, along with the determination of other biochemical markers (such as blood acetone and 3-beta-hydroxybutyrate, urine glucose and glycated haemoglobin), to confirm diabetic ketoacidosis as the cause of death.

    It is generally believed that pregnancy is mediated by a Th2 response, which includes cytokines that promote placental growth and are involved in inducing tolerance to the foetus. If the balance between Th1/and Th2-mediated cytokines is disrupted, systemic and local changes could predispose the foetus to future disease. Therefore, a shift in the Th1/Th2 balance during pregnancy, possibly caused by underlying environmental factors, could be associated with post-partum autoimmune disease in the offspring. Based on this presumption, we used celiac disease as a model to investigate whether autoimmunity is triggered in the foetus during early pregnancy, observed as changes in the mother's cytokine profile. Ten cytokines were measured by electro-chemi-luminescent multiplex ELISA in serum samples obtained from mothers during early pregnancy. Cases included women with children who had developed verified celiac disease before the age of 5, who were compared with other women as matched controls. We observed that 7 out of 10 cytokine levels were significantly increased in our case mothers when compared to controls. Five of these belonged to what is generally known as a Th1-mediated response (TNFα, IFNγ, IL-2, IL-1β and IL-12) and two were Th2 cytokines (IL-13 and IL-10). However, the IL-10 cytokine is known to have features from both arms of the immune system. These results were confirmed in a logistic regression model where five out of the initial seven cytokines remained. This study suggests that increase in Th1 serum cytokines may be associated with celiac disease in offspring.

    The elucidation of the changes of fetuin-A in the context of bariatric surgery. Twenty obese patients (8 males, 12 females; body mass index = 42.5±3.4 kg/m2) were studied at baseline and 6 months after bariatric surgery. Serum fetuin-A levels did not differ with regard to the presence of each individual component of the Metabolic Syndrome (MetS) at baseline, except for hypertriglyceridaemia [increased serum fetuin-A levels (p=0.011)]. Circulating fetuin-A was positively correlated with serum triglycerides (TG) (r=0.461, p=0.047) and negatively correlated with serum globulins (r=-0.477, p=0.033) and C-reactive protein (CRP) (r=-0.604, p=0.010), while it independently predicted TG at baseline. Circulating fetuin-A did not change during the 6 months either in the whole population or in the subgroups of patients who were positive for each individual component of MetS at baseline and negative for this component at 6 months of follow-up, except for hypertriglyceridaemia [reduction of serum fetuin-A levels (p=0.046)]. The subgroup of patients with a decrease in circulating fetuin-A during the 6 months was characterized by a smaller reduction of serum globulins (p=0.003) and CRP (p=0.049). The change in serum fetuin-A levels over the 6 months was positively correlated with the change in TG (r=0.592, p=0.006) and negatively correlated with the change in serum globulins (r=-0.523, p=0.018) and CRP (r=-.494, p=0.037). Circulating fetuin-A predicted serum triglycerides before as well as 6 months after bariatric surgery.

    There is inconsistent evidence on a possible association of vitamin D and androgen levels in men. We therefore aim to investigate the association of 25-hydroxyvitamin D (25(OH)D) with androgen levels in a cohort of middle-aged men. This cross-sectional study included 225 men with a median (interquartile range) age of 35 (30-41) years. We measured 25(OH)D, total testosterone (TT) and SHBG concentrations. Hypogonadism was defined as TT hypogonadism was 21.5% and lowest in men within 25(OH)D quintile 4 (82-102 nmol/L). We found a significantly increased risk of hypogonadism in men within the highest 25(OH)D quintile (>102 nmol/L) compared to men in quintile 4 (reference) in crude (OR 5.10, 1.51-17.24, p = 0.009) as well as in multivariate adjusted analysis (OR 9.21, 2.27-37.35, p = 0.002). We found a trend towards increased risk of hypogonadism in men within the lowest 25(OH)D quintile (≤43.9 nmol/L). In conclusion, our data suggest that men with very high 25(OH)D levels (>102 nmol/L) might be at an increased risk of hypogonadism. Furthermore, we observed a trend towards increased risk of hypogonadism in men with very low vitamin D levels indicating a U-shaped association of vitamin D levels and hypogonadism. With respect to risk of male hypogonadism, our results suggest optimal serum 25(OH)D concentrations of 82-102 nmol/L. © 2014 American Society of Andrology and European Academy of Andrology.

    In the present study, we examined the effect of pertussis toxin (PTX) administered centrally in a variety of stress-induced blood glucose level. Mice were exposed to stress after the pretreatment of PTX (0.05 or 0.1 µg) i.c.v. or i.t. once for 6 days. Blood glucose level was measured at 0, 30, 60 and 120 min after stress stimulation. The blood glucose level was increased in all stress groups. The blood glucose level reached at maximum level after 30 min of stress stimulation and returned to a normal level after 2 h of stress stimulation in restraint stress, physical, and emotional stress groups. The blood glucose level induced by cold-water swimming stress was gradually increased up to 1 h and returned to the normal level. The intracerebroventricular (i.c.v.) or intrathecal (i.t.) pretreatment with PTX, a Gi inhibitor, alone produced a hypoglycemia and almost abolished the elevation of the blood level induced by stress stimulation. The central pretreatment with PTX caused a reduction of plasma insulin level, whereas plasma corticosterone level was further up-regulated in all stress models. Our results suggest that the hyperglycemia produced by physical stress, emotional stress, restraint stress, and the cold-water swimming stress appear to be mediated by activation of centrally located PTX-sensitive G proteins. The reduction of blood glucose level by PTX appears to due to the reduction of plasma insulin level. The reduction of blood glucose level by PTX was accompanied by the reduction of plasma insulin level. Plasma corticosterone level up-regulation by PTX in stress models may be due to a blood glucose homeostatic mechanism.

    Insulin resistance (IR) was recognized as a risk factor for the occurrence of abortion in patients with polycystic ovary syndrome (PCOS). Chemerin was an adipokine which could induce IR and associated with reproductive process closely. However, few studies have inquired the relativity between chemerin and the occurrence of abortion in patients with PCOS. The aim of this study was to evaluate the relationship between serum chemerin and the occurrence of abortion in women with PCOS. We recruited 198 women with PCOS to participate in our study. On the third day of menstrual cycle or a random day in women with amenorrhea, we obtained their venous blood and measured the fasting insulin, fasting plasma glucose, total cholesterol, high density lipoprotein cholesterol, triglyceride, chemerin, and hormones including FSH, E2, P, PRL, LH, and T. Additionally, BMI, HOMA-IR and LH/FSH of each subject were calculated. Finally, 58 of them were included in the study, in which 30 of them had normal pregnancy and the other 28 had an early miscarriage. We compared the biochemical characteristics between the normal pregnancy group and abortion group by independent-samples t test. In our study, those with a normal pregnancy had a lower level of BMI, FINs, HOMA-IR, and chemerin compared to abortion patients (p PCOS patients (p PCOS. Thus, serum chemerin may serve as a biomarker to identify pregnant women with PCOS who are at particular risk for later abortion, and who may benefit from prevention strategies.

  10. Common variants related to serum uric acid concentrations are associated with glucose metabolism and insulin secretion in a Chinese population.

    Full Text Available Elevated serum uric acid concentration is an independent risk factor and predictor of type 2 diabetes (T2D. Whether the uric acid-associated genes have an impact on T2D remains unclear. We aimed to investigate the effects of the uric acid-associated genes on the risk of T2D as well as glucose metabolism and insulin secretion.We recruited 2,199 normal glucose tolerance subjects from the Shanghai Diabetes Study I and II and 2,999 T2D patients from the inpatient database of Shanghai Diabetes Institute. Fifteen single nucleotide polymorphisms (SNPs mapped in or near 11 loci (PDZK1, GCKR, LRP2, SLC2A9, ABCG2, LRRC16A, SLC17A1, SLC17A3, SLC22A11, SLC22A12 and SF1 were genotyped and serum biochemical parameters related to uric acid and T2D were determined.SF1 rs606458 showed strong association to T2D in both males and females (p = 0.034 and 0.0008. In the males, LRRC16A was associated with 2-h insulin and insulin secretion (p = 0.009 and 0.009. SLC22A11 was correlated with HOMA-B and insulin secretion (p = 0.048 and 0.029. SLC2A9 rs3775948 was associated with 2-h glucose (p = 0.043. In the females, LRP2 rs2544390 and rs1333049 showed correlations with fasting insulin, HOMA-IR and insulin secretion (p = 0.028, 0.033 and 0.052 and p = 0.034, 0.047 and 0.038, respectively. SLC2A9 rs11722228 was correlated with 2-h glucose, 2-h insulin and insulin secretion (p = 0.024, 0.049 and 0.049, respectively.Our results indicated that the uric acid-associated genes have an impact on the risk of T2D, glucose metabolism and insulin secretion in a Chinese population.

    Full Text Available BackgroundMetabolic health is an emerging concept that is highly correlated with various metabolic complications, and adipocytokines have been causally linked to a wide range of metabolic diseases. Thus, this study compared serum adipocytokine levels according to metabolic health and obesity status.MethodsFour hundred and fifty-six nondiabetic subjects (mean age, 40.5 years were categorized into four groups according to metabolic health and obesity status: metabolically healthy nonobese (MHNO, metabolically healthy obese (MHO, metabolically unhealthy nonobese (MUHNO, and metabolically unhealthy obese (MUHO. Being metabolically healthy was defined as the presence of fewer than two of the following five metabolic abnormalities: high blood pressure, high fasting blood glucose, high triglyceride, low high density lipoprotein cholesterol, and being in the highest decile of the homeostatic model assessment of insulin resistance index. Obesity status was assessed using body mass index (BMI, with obesity defined as a BMI higher than 25 kg/m2. Levels of serum interleukin-6 (IL-6, monocyte chemoattractant protein-1 (MCP-1, tumor necrosis factor α (TNF-α, and adipocyte fatty acid binding protein (A-FABP were also evaluated.ResultsOf the 456 subjects, 247 (54.2% were in the MHNO group, 66 (14.5% were in the MHO group, 66 (14.5% were in the MUHNO group, and 77 (16.9% were in the MUHO group. There were no significant differences in IL-6 or MCP-1 levels among the groups, but levels of TNF-α and A-FABP were significantly higher in the MUHNO group compared to the MHNO group.ConclusionHigh TNF-α and A-FABP levels are significantly associated with metabolically unhealthiness in nonobese Korean individuals.

    High GH and IGF I levels increase tubular phosphate reabsorption in patients with acromegaly. We aimed to investigate the utility of serum phosphorus levels as an indicator for predicting chance of remission in acromegaly patients. Fifty-one patients (n: 51; F: 24, M: 27) with diagnosis of acromegaly were included in the study. Plasma IGF-1, Phosphorus (P) and nadir GH levels on oral glucose tolerance test (OGTT) at the time of diagnosis were analysed retrospectively. Patients were classified into two groups according to their plasma P levels; P ≤ 4.5 mg/dl (Group-1, n: 23, 45.1%), P > 4.5 mg/dl (Group-2, n: 28, 54.9%). Two groups were compared according to remission status; remission (n: 27) and non-remission (n: 24). Remission was defined with absence of clinical symptoms, normal plasma IGF-1 (adjusted for age and gender) and GH levels (acromegaly patients. Further studies with wider spectrum are needed to make specific suggestions.

    Objective: To study the significance of changes of serum soluble intercellular adhesion molecule-1 (sICAM-1) and hyaluronic acid (HA) levels in patients with type-2 diabetes complicated with angiopathy. Methods: Serum levels of sICAM-1 (by ELISA) and HA (by RIA) were measured in 66 cases of type-2 diabetes complicated with angiopathy and 35 controls. Contents of fasting blood glucose (FBG), glycosylated hemoglobin (HbAIC) and urine microalbumin (MAlb) were also measured for correlation analysis studies. Results: Serum sICAM-1 and HA levels in patients with type-2 diabetic angiopathy were significantly higher than those in controls (p<0.01) and were closely positively correlated to the contents of FBG, HbAIC and MAlb (p<0.01). Conclusion: Higher serum sICAM-1 and HA levels may play some role in the pathogenesis of type-2 diabetic angiopathy

    Primary dysmenorrhea effects the life-quality of women negatively. The aim of this study was to evaluate heme oxygenase-1 (HO1) activity together with malondialdehyde (MDA) and nitric oxide (NO) levels in patients with primary dysmenorrhea. A total of 28 nulliparous women with the diagnosis of primary dysmenorrhea and 26 healthy controls were included in this study. On the first day of menstruation, all patients underwent ultrasound examination to exclude pelvic pathology and the visual analogue scale was applied to patients. Patient's visual analogue scale (VAS) scores, age, body mass index (BMI), menstrual cycle length (day), length of bleeding (day) were recorded. In the same day, fasting blood samples were taken from each patient for biochemical analysis. Serum MDA, NO and HO1 levels were found to be higher in women with primary dysmenorrhea compared to healthy controls (p = 0.012, p = 0.009, p dysmenorrhea. Antioxidant support might be helpful to reduce pain severity in primary dysmenorrhea.

    As part of its research program to study the late effects of radiation in survivors of the atomic bombs, the Atomic Bomb Casualty Commission (ABCC) in conjunction with the Japanese National Institute of Health (JNIH), conducts biennial medical examinations on the selected population which comprises the ABCC-JHIN Adult Health Study sample. The patients herein described as Groups 1 and 2 were selected from among those examined in Nagasaki who had had a hemoglobin value of less than 11.0 g/100 ml at examination 2 years previously and who had responded to iron therapy sufficiently to justify a diagnosis of iron deficiency anemia. Almost all were women of child bearing age. The effect of iron therapy on the level of serum B/sub 12/ was investigated. Of 58 patients so studied, 46 showed some rise in post-treatment levels of B/sub 12/. This is evaluated as indicating that gastric secretion of intrinsic factor is depressed in the majority of iron deficient patients.

  16. The association of serum leptin levels with metabolic diseases

    Jen-Pi Tsai

    2017-01-01

    Full Text Available Leptin is a 167-amino-acid protein released by white adipose tissue and encoded by the obese gene. It has a role as a negative regulator of appetite control through sending a satiety signal to act on receptors within the hypothalamus. At normal levels, leptin can exert its effects on weight regulation according to white fat mass, induce sodium excretion, maintain vascular tone, and repair the myocardium. Beyond these effects, elevated serum leptin levels have been implicated in the pathogenesis of metabolic syndrome, diabetes mellitus, hypertension, and multiple cardiovascular diseases. In addition, hyperleptinemia had been reported to contribute to renal diseases through multiple mechanisms resulting in glomerulopathy presenting with a decreased glomerular filtration rate, increased albuminuria, and related clinical symptoms, which are pathophysiological features of chronic kidney disease. Because these cardiovascular and metabolic disorders are great challenges for physicians, understanding the related pathophysiological association with leptin might become a valuable aid in handling patients in daily clinical practice. This review will discuss the roles of leptin in the regulation of biological functions of multiple organs beyond the maintenance of feeding and metabolism.

    Interleukin-22 (IL-22) has beneficial effects on body weight, insulin resistance and inflammation in different mouse models, but its relevance for the development of type 2 diabetes in humans is unknown. We aimed to identify correlates of serum IL-22 levels and to test the hypothesis that higher IL-22 levels are associated with lower diabetes incidence. Cross-sectional associations between serum IL-22, cardiometabolic risk factors and glucose tolerance status were investigated in 1107 persons of the population-based KORA F4 study. The prospective association between serum IL-22 and incident type 2 diabetes was assessed in 504 initially non-diabetic study participants in both the KORA F4 study and its 7-year follow-up examination KORA FF4, 76 of whom developed diabetes. Male sex, current smoking, lower HDL cholesterol, lower estimated glomerular filtration rate and higher serum interleukin-1 receptor antagonist were associated with higher IL-22 levels after adjustment for confounders (all P < 0.05). Serum IL-22 showed no associations with glucose tolerance status, prediabetes or type 2 diabetes. Baseline serum IL-22 levels (median, 25th/75th percentiles) for incident type 2 diabetes cases and non-cases were 6.28 (1.95; 12.35) and 6.45 (1.95; 11.80) pg/ml, respectively (age and sex-adjusted P = 0.744). The age and sex-adjusted OR (95% CI) per doubling of IL-22 for incident type 2 diabetes of 1.02 (0.85; 1.23) was almost unchanged after consideration of further confounders. High serum levels of IL-22 were positively rather than inversely associated with several cardiometabolic risk factors. However, these associations did not translate into an increased risk for type 2 diabetes. Thus, our data argue against the utility of IL-22 as biomarker for prevalent or incident type 2 diabetes in humans, but identify potential determinants of IL-22 levels which merits further research in the context of cardiovascular diseases.

    Objective: To study the effects of Huang Qi and Huang Lian on serum P-selectin, tumor necrosis factor-α (TNF-α), glucose and glycosylated hemoglobin (HbAlc) levels in patients with type two diabetes mellitus (DM). Methods: Sixty DM2 patients were divided randomly into 2 equal numbered groups: one group were treated with routine hypoglycemic medicine, in other group, Jinqi hypoglycemic tablets were added besides western medicine. Fasting blood glucose, two hour postprandial glucose, HbAlc, P-SLT and TNF-α levels were measured detected before and after three months' treatment. Results: There were no significant differences between the plasma glucose, HbAlc, P-SLT and TNF-α levels (P>0.05) in the JinQi group and western medicine group before treatment. Fasting plasma glucose and postprandial glucose were decreased after treatment in both groups. HbAlc, P-SLT and TNF-α levels were significantly decreased after treatment (P<0.05, P<0.01, P<0.01) in JinQi group. Conclusion: On the basis of treatment with western medicine, additional Huang Lian and Huang Qi could further decrease HbAlc, P-SLT and TNF-α levels, stabilize blood glucose and provide better therapeutic results in patients with type 2 diabetes mellitus.

    The serum/glucose deprivation (SGD)-induced cell death in cultured PC12 cells represents a useful in vitro model for the study of brain ischemia and neurodegenerative disorders. Nigella sativa L. (family Ranunculaceae) and its active component thymoquinone (TQ) has been known as a source of antioxidants. In the present study, the protective effects of N. sativa and TQ on cell viability and reactive oxygen species (ROS) production in cultured PC12 cells were investigated under SGD conditions. PC12 cells were cultured in DMEM medium containing 10% (v/v) fetal bovine serum, 100 units/ml penicillin, and 100 microg/ml streptomycin. Cells were seeded overnight and then deprived of serum/glucose for 6 and 18 h. Cells were pretreated with different concentrations of N. sativa extract (15.62-250 microg/ml) and TQ (1.17-150 microM) for 2 h. Cell viability was quantitated by MTT assay. Intracellular ROS production was measured by flow cytometry using 2',7'-dichlorofluorescin diacetate (DCF-DA) as a probe. SGD induced significant cells toxicity after 6, 18, or 24 h (P < 0.001). Pretreatment with N. sativa (15.62-250 microg/ml) and TQ (1.17-37.5 microM) reduced SGD-induced cytotoxicity in PC12 cells after 6 and 18 h. A significant increase in intracellular ROS production was seen following SGD (P < 0.001). N. sativa (250 microg/ml, P < 0.01) and TQ (2.34, 4.68, 9.37 microM, P < 0.01) pretreatment reversed the increased ROS production following ischemic insult. The experimental results suggest that N. sativa extract and TQ protects the PC12 cells against SGD-induced cytotoxicity via antioxidant mechanisms. Our findings might raise the possibility of potential therapeutic application of N. sativa extract and TQ for managing cerebral ischemic and neurodegenerative disorders.

    2004-01-01

    Objective: To investigate the change of serum cortisol levels and its correlation to blood sugar and serum insulin levels in patients with type 2 diabetes mellitus. Methods: Blood sugar with oxidase method and serum cortisol insulin levels with RIA (8 AM fasting specimen) were measured in 26 patients with type 2 diabetes mellitus and 30 controls. Results: The serum cortisol levels in the diabetic patients were significantly higher than those in the controls (P<0.01). The cortisol levels were positively correlated to the blood sugar levels (r=0.32, p<0.01), but not correlated to insulin levels. Conclusion: There were cortisol secretion disturbances in patients with type 2 diabetes

    To investigate the correlation of the levels of interleukin-8 (IL-8) and IL-6 in the prostatic fluid with serum levels of serum prostate-specific antigen (PSA) in patients with benign prostatic hyperplasia (BPH) complicated by prostatitis. A series of 211 patients undergoing surgery of BPH were divided into BPH group (n=75) and BPH with prostatitis group (n=136) according to the white blood cell count in the prostatic fluid. The clinical and laboratory findings were compared between the two groups, and stepwise regression analysis was used to assess the association of IL-8 and IL-6 with serum PSA level. No significant differences were found in age, BMI, blood pressure, blood glucose, blood lipids, IPSS score, PSA-Ratio, or prostate volume between the two groups (Pprostatitis had significantly increased serum PSA and prostate fluid IL-8 and IL-6 levels compared with those without prostatitis (Pprostatic fluid were all positively correlated with serum PSA level. Prostatitis is an important risk factor for elevated serum PSA level in patients with BPH, and both IL-8 and IL-6 levels in the prostatic fluid are correlated with serum PSA level.

    Full Text Available Background. One of the mechanisms that has been suggested for obesity related metabolic disturbances is obesity-induced inflammation. Pro-inflammatory cytokines generated in adipose tissue can increase hepatic synthesis of inflammation-sensitive plasma proteins (ISPs including ceruloplasmin (Cp. In this study we aimed to investigate the relation between serum Cp level and obesity. Methods. 61 persons with body mass index (BMI ≥ 25 kg/m2 (case group and 61 persons with BMI < 25 kg/m2 (control group were included in this study with a case-control design. Serum Cp levels, triglyceride level, fating blood glucose, total cholesterol, LDL-cholesterol, HDL-cholesterol and hsCRP were measured in both groups. Results. We did not observe any significant association between serum Cp level and BMI in all subjects [OR: 1.02 (CI, 0.967 to 1.07] and in case (β=0.012, P=0.86 and control groups (β=0.49, P=0.07 separately. However, in control group, this positive association was marginally significant. We found a positive correlation between serum Cp level and serum triglyceride level. Conclusion. Serum Cp level was not related to obesity in this group of subjects. None of the baseline variables could predict obesity in this group of subjects, including serum Cp level, FBS, total cholesterol, LDL and HDL- cholesterols and hsCRP.

    Full Text Available The objective of this study was to comparatively evaluate the levels of beta hydroxy butyrate (BHB, glucose, protein and albumin in serum of healthy Holstein cows and those with subclinical ketosis. In this survey, blood samples were collected at two stages from cows selected at 7 dairy farms in Shahriar province of Tehran. Five to 7 ml of blood were taken from the coccygeal vein of 100 cows during the last week of pregnancy when the animals were dry and once again 2 months after parturition from the same cows, their sera separated and the amounts of BHB, glucose, protein and albumin determined by enzymatic techniques and commercially available kits. With the cut point of BHB at 1.2, 1.4 and 1.7 mmol/lit, the percentage of cows affected with subclinical ketosis were 18, 14 and 4 percent, respectively. Mean levels of BHB in ketotic cows was significantly higher than healthy cows before and after parturition while mean levels of glucose, protein and albumin was significantly lower during the same periods (P

    Primary hyperparathyroidism has been associated with increased incidence of morbidity and mortality of the cardiovascular system. The etiopathogenetic mechanisms underlying this association are still not completely clear. Accumulating evidence suggested that a disintegrin and metalloproteinase with thrombospondin-like motifs (ADAMTS) has a role in the development of inflammation and atherosclerosis. In this study, we aimed to determine whether there is a change in serum levels of ADAMTS1, ADAMTS4, carotid intima-media thickness, and cardiovascular risk score after the surgery and also whether there is a relationship between ADAMTS levels and cardiovascular risk score in hypercalcemic primary hyperparathyroidism patients. The study included the 48 consecutive newly diagnosed patients with primary hyperparathyroidism. The patients were evaluated before and six months after parathyroidectomy. The Framingham score is used to calculate cardiovascular risk. Serum ADAMTS levels were determined by a human enzyme-linked immunoassay in all subjects. The fasting glucose, fasting insulin levels and HOMA values were decreased significantly in all patients after surgery compared to the pretreatment values (p hyperparathyroidism compared to the preoperative values (p  0.05). There were statistically significant relationship between cardiovascular risk score and waist/hip ratio, calcium, LDL-cholesterol, carotid intima-media thickness, ADAMTS4 values. Based on the results of the present study, fasting glucose, fasting insulin levels, ADAMTS1, ADAMTS4, and carotid intima-media thickness might be an additional parameters during the management of patients with primary hyperparathyroidism, since these factors might improve after surgery.

    Glucose and creatinine are two of the most frequently measured substances in human blood/serum for assessing the health status of individuals. Because of their clinical significance, CCQM-K11 glucose in human serum and CCQM-K12 creatinine in human serum were the fourth and fifth key comparisons (KCs) performed by the Organic Analysis Working Group (OAWG). These KCs were conducted in parallel and were completed in 2001. The initial subsequent KCs for glucose, CCQM-K11.1, and creatinine, CCQM-K12.1, were completed in 2005. Measurements for the next KCs for these two measurands, CCQM-K11.2 and CCQM-K12.2, were completed in 2013. While designed as subsequent KCs, systematic discordances between the participants' and the anchor institution's results in both comparisons lead the OAWG to request reference results from two experienced laboratories that had participated in the 2001 comparisons. Based on the totality of the available information, the OAWG converted both CCQM-K11.2 and CCQM-K12.2 to 'Track C' KCs where the key comparison reference value is estimated by consensus. These comparisons highlighted that carrying out comparisons for complex chemical measurements and expecting to be able to treat them under the approaches used for formal CIPM subsequent comparisons is not an appropriate strategy. The approach used here is a compromise to gain the best value from the comparison; it is not an approach that will be used in the future. Instead, the OAWG will focus on Track A and Track C comparisons that are treated as stand-alone entities. Participation in CCQM-K11.2 demonstrates a laboratory's capabilities to measure a polar (pKow > 2), low molecular mass (100 g/mol to 500 g/mol) metabolite in human serum at relatively high concentrations (0.1 mg/g to 10 mg/g). Participation in CCQM-K12.2 demonstrates capabilities to measure similar classes of metabolites at relatively low concentrations (1 μg/g to 30 μg/g). The capabilities required for the analysis of complex

    Background It is not clear whether elevated uric acid is a risk factor for the onset of impaired fasting glucose after stratifying by baseline fasting plasma glucose levels. We conducted a community-based retrospective longitudinal cohort study to clarify the relationship between uric acid levels and the onset of impaired fasting glucose, according to baseline fasting plasma glucose levels. Methods We enrolled 6,403 persons (3,194 men and 3,209 women), each of whom was 18–80 years old and had >2 annual check-ups during 2003–2010. After excluding persons who had fasting plasma glucose levels ≥6.11 mM and/or were currently taking anti-diabetic agents, the remaining 5,924 subjects were classified into quartiles according to baseline fasting plasma glucose levels. The onset of impaired fasting glucose was defined as fasting plasma glucose ≥6.11 mM during the observation period. Results In the quartile groups, 0.9%, 2.1%, 3.4%, and 20.2% of the men developed impaired fasting glucose, respectively, and 0.1%, 0.3%, 0.5%, and 5.6% of the women developed impaired fasting glucose, respectively (P trend fasting glucose in men with highest-quartile fasting plasma glucose levels (adjusted hazard ratio, 1.003; 95% confidence interval, 1.0001–1.005, P = 0.041). Conclusions Among men with high fasting plasma glucose, hyperuricemia may be independently associated with an elevated risk of developing impaired fasting glucose. PMID:25237894

    Full Text Available The aim of this clinical study was to determine whether there is a relationship between total serum testosterone, free testosterone, FSH (Follicle-Stimulating Hormone, LH (Luteinizing Hormone and serum prostate specific antigen (PSA levels. We postulated that such a correlation existed then the use of hormone specific reference ranges might enhance the usefullness of PSA concentrations <2.5 ng/mL as a marker for prostate cancer.

  12. Serum ADEPONECTIN Level In Children And Adolescents With Type I Diabetes Mellitus And Its Association With Microvascular Complications

    MOAWAD, A.T.

    2010-01-01

    Adiponectin, an adipo cytokine, is secreted from the adipose tissue and plays an important role in obesity, type II diabetes and cardiovascular disease. This study aimed to determine the concentration of serum adiponectin in type I diabetic children and to establish its association with microvascular complications. For this reason, weight (kg), height (m), body mass index (BMI) (kg/m2), random blood sugar, HbAIc, kidney functions, urinary microalbuminuria, lipid profiles and serum adiponectin were assessed in 25 children (11 males, 14 females) with type I diabetes and twenty healthy control children. Careful history, clinical examination, acetomorphine and pirbuterol assessment were done for all patients and controls. The diabetic patients were stratified depending on the pubertal stage into pre-pubertal group and pubertal group, and according to gender into male group and female group. The results obtained displayed significant elevated values for random blood glucose (P<0.001), HbAIc (P<0.001), total cholesterol (P<0.05), low density lipoprotein (LDL) (P<0.05), BUN (P<0.001), creatinine (P<0.05), urinary microalbuminuria (P<0.001) and serum adiponectin (P<0.001) in diabetic children and control. In patients suffering from microvascular diabetic complications as retinopathy, nephropathy and neuropathy, serum adiponectin level showed high significant increase in patients with diabetic nephropathy and neuropathy than without. On the other hand, patients with retinopathy had no significant increase in serum adiponectin as compared with patients without retinopathy but this result may be due to small sample size. Positive significant correlation was detected between serum adiponectin and HbAIc, total cholesterol and urinary microalbuminuria in the same patients. Negative significant correlation was observed between serum adiponectin level and body mass index (BMI). It could be concluded that serum adiponectin which increased in diabetic children than healthy control

    Serum bilirubin level was negatively associated with the prevalence of metabolic syndrome (MetS) in previous cross-sectional studies. However, bilirubin variance preceding the development of MetS has yet to be investigated. We aimed to determine the effect of change in bilirubin concentration on the risk of incident MetS in healthy Korean adults. We conducted a retrospective longitudinal study of subjects who had undergone at least four yearly health check-ups between 2006 and 2012. Of 24,185 total individuals who received annual check-ups, 11,613 non-MetS participants with a baseline bilirubin level not exceeding 34.2 μmol/l were enrolled. We evaluated the association between percent change in bilirubin and risk of incident MetS. During 55,407 person-years of follow-up, 2,439 cases of incident MetS developed (21.0%). Baseline serum bilirubin level clearly showed no association with the development of MetS in men but an independent significant inverse association in women which attenuated (hence may be mediated) by elevated homeostatic model assessment index 2 for insulin resistance (HOMA2-IR). However, increased risk for incident MetS was observed in higher percent change in bilirubin quartiles, with hazard ratios of 2.415 (95% CI 2.094-2.785) in men and 2.156 (95% CI 1.738-2.675) in women in the fourth quartile, compared to the lowest quartile, after adjusting for age, smoking status, medication history, alanine aminotransferase, uric acid, estimated glomerular filtration rate, fasting glucose, baseline diabetes mellitus prevalence, systolic blood pressure, waist circumference, and body mass index. The hazard ratios per one standard deviation increase in percent change in bilirubin as a continuous variable were 1.277 (95% CI 1.229-1.326) in men and 1.366 (95% CI 1.288-1.447) in women. Increases in serum bilirubin concentration were positively associated with a higher risk of incident MetS. Serum bilirubin increment might be a sensitive marker for the development

    Over the past 50 years, dietary restriction (DR) has been shown to extend the life span of a wide variety of organisms. A hallmark feature of DR is improved glucose homeostasis resulting in increased glucose tolerance and insulin sensitivity of animals ranging from rodents to humans. In this study, we demonstrate the early effects of varying levels of DR on glucose tolerance. Within 10 days of 40% DR, glucose tolerance was significantly improved and by 120 days; 10 and 20% DR also showed enhanced glucose tolerance. All three levels of DR showed reduced adiposity, increased expression of genes involved in fat turnover, and a reduction in the expression for markers of inflammation. Studies have shown that mice fed a DR diet retained metabolic memory in terms of improved glucose tolerance even after DR is discontinued. We show that 40% DR not only has an early effect on glucose tolerance but also maintained it after DR was discontinued for 2 months. Therefore, improvement in glucose tolerance is brought about by all three levels of DR but the metabolic memory is not dose responsive.

    IL-10 expression limits inflammation and restricts the size of CNS damage from stroke. In this study, we examined the correlation between cerebral infarction (CI) and serum levels of interleukin-10 (IL-10) using a combination of case-control study and meta-analysis of published data, with an aim of understanding the relevance of serum IL-10 levels to CI development. This study enrolled a total of 169 CI patients admitted to the Second Hospital of Hebei Medical University between May 2011 and November 2014. During the same period, a group of 145 individuals were recruited at the same hospital as healthy controls after thorough physical examination. Serum IL-10 levels were measured by enzyme-linked immunosorbent assay (ELISA). SPSS 19.0 (IBM, 2010, Chicago, IL, USA) and Comprehensive Meta-Analysis 2.0 (CMA 2.0) software were used for data analysis. Serum levels of IL-10 (pg/mL) were significantly lower in CI patients when compared to healthy controls (15.36 ± 3.21 vs. 21.64 ± 5.17, t = 13.12, P 0.05). Logistic regression analysis indicated that, with the exception of triglyceride (TG) and uric acid (UA) levels (both P > 0.05), the other seven parameters, including fasting blood glucose (FPG), total cholesterol, low-density lipoprotein (LDL), high-density lipoprotein (HDL), creatinine (Cr), systolic blood pressure (SBP), and diastolic blood pressure (DBP), strongly correlated with CI development (all P analysis of pooled data from nine case-control studies revealed an inverse correlation between the serum IL-10 levels and CI (SMD = 1.797, 95% CI 0.785~2.810, P = 0.001). Subgroup analysis based on country showed that low serum levels of IL-10 may be the major risk factor for CI in Croatia (SMD = 2.961, 95% CI 2.480~3.443, P analysis based on ethnicity showed that IL-10 serum levels and CI displayed negative relationship in Asians (SMD = 2.522, 95% CI 0.468~4.576, P = 0.016) but not in Caucasians (P > 0.05). Our study provided convincing evidence that the patients

  16. Serum Biotin Levels in Women Complaining of Hair Loss.

    Trüeb, Ralph M

    2016-01-01

    Biotin is a coenzyme for carboxylase enzymes that assist various metabolic reactions involved in fatty acid synthesis, branched-chain amino acid catabolism, and gluconeogenesis important for maintenance of healthy skin and hair. Due to its availability, affordability, and effective marketing for this purpose, biotin is a popular nutritional supplement for treatment of hair loss. However, there are little data on the frequency of biotin deficiency in patients complaining of hair loss and on the value of oral biotin for treatment of hair loss that is not due to an inborn error of biotin metabolism or deficiency. The aim of this study was to determine the frequency and significance of biotin deficiency in women complaining of hair loss. Biotin deficiency was found in 38% of women complaining of hair loss. Of those showing diffuse telogen effluvium in trichograms (24%), 35% had evidence of associated seborrheic-like dermatitis. About 11% of patients with biotin deficiency had a positive personal history for risk factors for biotin deficiency. The custom of treating women complaining of hair loss in an indiscriminate manner with oral biotin supplementation is to be rejected, unless biotin deficiency and its significance for the complaint of hair loss in an individual has been demonstrated on the basis of a careful patient history, clinical examination, determination of serum biotin levels, and exclusion of alternative factors responsible for hair loss.

    The role played by the microenvironment in cancer induction, promotion and progression is crucial. Emerging evidence suggests that cytokines, chemokines and growth factors are major players in carcinogenesis. Therefore, a detailed understanding of factors and mechanisms associated with the processes leading from inflammation to cancer could improve the therapeutic strategies against this disease. We have used hepatocarcinoma as our model in this study. We evaluated the serum levels of 50 different cytokines, chemokines and growth factors in patients affected by HCC with chronic HCV-related hepatitis and liver cirrhosis using multiplex biometric ELISA-based immunoassay. Our data showed that some pro-inflammatory molecules were significantly up-regulated in these patients, and highlighted the complexity of the cytokine network in this disease. This work suggests the need to monitor these proteins in order to define a profile that could characterize patients with HCC or to help identify useful markers. This could lead to better definition of the disease state, and to an increased understanding of the relationships between chronic inflammation and cancer.

    2017-01-01

    Full Text Available Background. To investigate whether serum alanine aminotransferase (ALT levels within normal range were associated with augmentation index (AIx and cardiometabolic risk factors in nondrinkers and drinkers in Chinese community-dwelling population. Methods. There were 4165 participants with serum ALT levels within normal range. Results. Alcohol drinking was observed in 1173 participants (28.2%. In multivariate analysis, serum ALT levels of nondrinkers were independently associated with age, sex, body mass index (BMI, hypertension, diabetes mellitus, diastolic blood pressure, triglyceride, low-density lipoprotein-cholesterol (LDL-c, and AIx, while serum ALT levels of drinkers were independently associated with age, sex, BMI, triglyceride, and LDL-c (p<0.05 for all. Conclusions. Associations of serum ALT levels within normal range with age, sex, body height and weight, and blood lipid were simultaneously present in participants with and without alcohol drinking, while associations of serum ALT levels within normal range with AIx, blood pressure, and glucose were seen in nondrinkers rather than in drinkers. These findings not only provide the evidence that serum ALT levels, even within the normal range, have different associations with arteriosclerosis and cardiometabolic risk factors in nondrinkers and drinkers but also are helpful in understanding the underlying pathophysiologic mechanisms linking the hepatic function to arteriosclerosis and cardiometabolic risk factors.

    Zinc (Zn) is known to interact with lead (Pb) and cadmium (Cd) reversing their toxicity and reducing their concentrations. However, lactating women are at high risk of developing Zn deficiency, which may result in Pb and Cd intoxication or increased exposure of breast-fed infants to Pb and Cd from breast milk. The aim of this study was to determine Zn, Pb, and Cd concentrations and examine their relationship in serum and breast milk of lactating women in Ibadan, Nigeria. Ninety-two lactating women were recruited into this study. Anthropometric measurements were assessed by standard methods while serum and breast milk concentrations of Zn, Pb, and Cd were assessed by atomic absorption spectrophotometry. Data analyzed statistically by Student's t test, Pearson's correlation coefficient, and a multiple regression model were significant at p < 0.05. Zn deficiency was observed in 12 (17.1%) of lactating women. Breast milk levels of Zn, Pb, and Cd were significantly higher than their levels in serum, whereas the ratios Zn:Pb and Zn:Cd in milk were significantly less than serum ratios. Significant negative correlation was observed between milk Pb and serum Zn:Pb while milk Cd correlated positively with milk Zn. Significant positive correlations were observed between serum Zn and serum Zn:Pb, serum Zn and serum Zn:Cd, as well as serum Zn:Cd and serum Zn:Pb. Serum Cd and serum Zn were significantly negatively related. Significant negative correlations between serum Pb and serum Zn:Pb as well as milk Zn:Pb. Serum Cd and serum Zn:Pb as well as serum Zn:Cd correlated negatively. Milk Cd and Zn/Cd positively related with milk Pb while milk Zn was a negatively related with milk Pb in a multiple regression model ( R 2 = 0.333; p = 0.023). Breast milk may be contaminated by toxic metals. However, Zn supplementation in deficient mothers may protect maternal and infant health.

    Serum thymus and activation-regulated chemokine (TARC) levels are associated with the disease activity of patients with atopic dermatitis (AD) and sensitively reflect short-term changes in skin conditions. The main treatment for AD is topical agent application. This study investigated the relationship between serum TARC levels and the dosage of topical agents, including corticosteroids and/or tacrolimus, in patients with AD. The serum TARC levels of 56 AD patients and the amounts of topical agents prescribed to them were investigated retrospectively. The weekly reduction in serum TARC levels and weekly dosage of topical agents among AD patients were compared and their associations were evaluated. The dosage of topical agents was closely related to serum TARC levels. One gram of strong rank steroid or the equivalent amount of steroid/tacrolimus is required to reduce serum TARC levels by 9.94 pg/mL weekly in moderate to severe AD patients. Higher initial TARC levels require more topical agent, which results in a more rapid decrease in TARC levels. The serum TARC levels and eosinophil numbers in peripheral blood are significantly correlated. Serum TARC level improvement and topical agent dosage are strongly correlated. TARC and eosinophil numbers are significantly correlated, but the wider range of TARC levels seems to be clinically more useful for monitoring AD severity. The serum TARC level is a very sensitive biomarker for monitoring the severity and treatment response in AD.

    In FDG-PET for abdominal malignancy, the liver may be assumed as an internal standard for grading abnormal FDG uptake both in early images and in delayed images. However, physiological variables of FDG uptake by the liver, especially the effects of blood glucose level, have not yet been elucidated. Methods: FDG-PET studies of 70 patients examined at 50 to 70 min after injection (60{+-}10 min: early images) and of 68 patients examined at 80 to 100 min after injection (90{+-}10 min: delayed images) were analyzed for liver FDG uptake. Patients having lesions in the liver, spleen and pancreas; patients having bulk tumor in other areas; and patients early after chemotherapy or radiotherapy were excluded; also, patients with blood glucose level over 125 mg/dl were excluded. Results: Mean standardized uptake value (SUV) of the liver, blood glucose level and sex showed no significant differences between early images and delayed images. However, liver SUV in the delayed image showed a larger variation than that in the early image and showed significant correlation to blood glucose level. The partial correlation coefficient between liver SUV and blood glucose level in the delayed image with adjustment for sex and age was 0.73 (P<.0001). Multivariate regression coefficient (95% confidence interval) of blood glucose was 0.017 (0.013-0.021). Conclusion: Blood glucose level is an important factor affecting the normal liver FDG uptake in nondiabetic patients. In the case of higher glucose level, liver FDG uptake is elevated especially in the delayed image. This may be due to the fact that the liver is the key organ responsible for glucose metabolism through gluconeogenesis and glycogen storage.

    For this cross-sectional study, we aimed to elucidate whether higher glycosylated hemoglobin (HbA1c) and glucose levels exert a negative impact on memory performance and hippocampal volume and microstructure in a cohort of healthy, older, nondiabetic individuals without dementia. In 141 individuals (72 women, mean age 63.1 years ± 6.9 SD), memory was tested using the Rey Auditory Verbal Learning Test. Peripheral levels of fasting HbA1c, glucose, and insulin and 3-tesla MRI scans were acquired to assess hippocampal volume and microstructure, as indicated by gray matter barrier density. Linear regression and simple mediation models were calculated to examine associations among memory, glucose metabolism, and hippocampal parameters. Lower HbA1c and glucose levels were significantly associated with better scores in delayed recall, learning ability, and memory consolidation. In multiple regression models, HbA1c remained strongly associated with memory performance. Moreover, mediation analyses indicated that beneficial effects of lower HbA1c on memory are in part mediated by hippocampal volume and microstructure. Our results indicate that even in the absence of manifest type 2 diabetes mellitus or impaired glucose tolerance, chronically higher blood glucose levels exert a negative influence on cognition, possibly mediated by structural changes in learning-relevant brain areas. Therefore, strategies aimed at lowering glucose levels even in the normal range may beneficially influence cognition in the older population, a hypothesis to be examined in future interventional trials.

  3. Using meta-differential evolution to enhance a calculation of a continuous blood glucose level.

    Koutny, Tomas

    2016-09-01

    We developed a new model of glucose dynamics. The model calculates blood glucose level as a function of transcapillary glucose transport. In previous studies, we validated the model with animal experiments. We used analytical method to determine model parameters. In this study, we validate the model with subjects with type 1 diabetes. In addition, we combine the analytic method with meta-differential evolution. To validate the model with human patients, we obtained a data set of type 1 diabetes study that was coordinated by Jaeb Center for Health Research. We calculated a continuous blood glucose level from continuously measured interstitial fluid glucose level. We used 6 different scenarios to ensure robust validation of the calculation. Over 96% of calculated blood glucose levels fit A+B zones of the Clarke Error Grid. No data set required any correction of model parameters during the time course of measuring. We successfully verified the possibility of calculating a continuous blood glucose level of subjects with type 1 diabetes. This study signals a successful transition of our research from an animal experiment to a human patient. Researchers can test our model with their data on-line at https://diabetes.zcu.cz.

    2012-01-01

    Full Text Available Background/Aim. Periodontitis is a local inflammatory process mediating destruction of periodontal tissues triggered by bacterial insult. However, this disease is also characterized by systemic inflammatory host responses that may contrbute, in part, to the recently reported increased risk for systemic diseases, including an altered lipid metabolism. On the other hand, many people in the world are affected by hyperlipidemia, which is a known risk faktor for atherosclerosis. The aim of this study was to determine the relationship between periodontal disease and blood lipid levels. Methods. A total of 50 patients with periodontitis included in this study had no documented history of recent acute coronary events. The healthy, non-periodontal subjects (comparison group comprised 25 subjects. All the patients were periodontology examined and completed a medical history. Dental plaque index, probing depth, gingival index bleeding on probing and clinical attechment levels were recorded. Blood samples were taken on admission for measurements of serum total cholesterol, triglycerides, hight density lipoprotein cholesterol (HDL-cholesterol, and low density lipoprotein cholesterol (LDL-cholesterol. Results. The obtained results showed that mean levels of cholesterol (6.09 ± 1.61 mmol/L, triglycerdes (2.19+1.67mmol/l and LDL cholesterol (4.09 ± 1.40 mmol/L in individuals with periodontitis were higer, and levels od HDL (1.43 ± 0.51 mmol/L was lower than those of individuals without periodontitis (4.86 ± 1.37; 1.14 ± 0.71; 3.18 ± 0.64; 1.53 ± 0.32 mmol/L, respectively. Conclusion. This study confirms a significant relationship between periodontal disease, regardless its intensity, and blood lipid levels in the studied population. The results imply that periodontitis may be a risk factor and may contribute to the pathogenesis of atherosclerosis and cardiovascular diseases (CVD. However, future prospective randomized studies have to determine whether

  5. Dietary Fructose and Glucose Differentially Affect Lipid and Glucose Homeostasis1–3

    Schaefer, Ernst J.; Gleason, Joi A.; Dansinger, Michael L.

    2009-01-01

    Absorbed glucose and fructose differ in that glucose largely escapes first-pass removal by the liver, whereas fructose does not, resulting in different metabolic effects of these 2 monosaccharides. In short-term controlled feeding studies, dietary fructose significantly increases postprandial triglyceride (TG) levels and has little effect on serum glucose concentrations, whereas dietary glucose has the opposite effects. When dietary glucose and fructose have been directly compared at ∼20–25% ...

    Objective To evaluate some risk factors for cardiovascular diseases in feeding and eating disorders, the degree of lipid abnormalities was investigated in a large Japanese cohort of different groups of feeding and eating disorders, according to the Japan Atherosclerosis Society Guidelines for the Prevention of Atherosclerotic Cardiovascular Diseases 2012 (JAS Guidelines 2012). Methods Participants in the current study included 732 women divided into four groups of feeding and eating disorders: anorexia nervosa, restricting type (AN-R); anorexia nervosa, binge-eating/purging type; bulimia nervosa (BN); and binge-eating disorder (BED). We measured the serum levels of total cholesterol, high-density-lipoprotein (HDL) cholesterol, and triglyceride in these participants. Low-density-lipoprotein (LDL) cholesterol and non-HDL cholesterol levels were also calculated. Results The concentrations of LDL cholesterol and non-HDL cholesterol were widely distributed in all groups. When the LDL cholesterol risk was defined as ≥120 mg/dL and the non-HDL cholesterol risk as ≥150 mg/dL, according to the JAS Guidelines 2012, the proportion of LDL cholesterol risk ranged from 29.6% (BN) to 38.6% (AN-R), and the proportion of non-HDL cholesterol risk ranged from 17.8% (BN) to 30.1% (BED). Conclusion The present findings suggest the existence of LDL cholesterol risk and non-HDL cholesterol risk in all groups of eating disorders. Given the chronicity of this condition, the development of elevated concentrations of LDL cholesterol and non-HDL cholesterol at an early age may increase the risk of cardiovascular diseases.

    Objectives:To see the effects of age, gender and diabetes on serum lipid levels. Study type, settings and duration:Cross sectional analytical study conducted at PMRC Research Centre, Fatima Jinnah Medical College,Lahore from Jun-Dec 2011. Materials and Methods: One hundred type 2 diabetes mellitus and equal numbers of gender matched healthy controls were randomly selected for the study. After an overnight fasting, blood specimens were drawn for lipid profile where total cholesterol,high density lipoprotein cholesterol and triglycerides were measured by standard enzymatic endpoint methods and LDL-cholesterol by Friedweld's formula. Statistical analysis was done using SPSS-15. Results Odd ratios of age for total cholesterol (OR 1.198); high density lipoprotein cholesterol (OR 1.144); and low density lipoprotein cholesterol (OR 1.576) revealed that subjects aged 45 years or more had greater risk of having deranged lipid levels. Female gender had higher high density lipoprotein cholesterol (p 0.000); and triglycerides (p 0.001). Odd ratios of men for total cholesterol (OR 0.775); high density lipoprotein cholesterol(OR 0.183); and low density lipoprotein Cholesterol (OR 0.683) illustrated that men were significantly less prone to dyslipidemia than women. Odd ratio of diabetes for high density lipoprotein cholesterol (OR 1.802) suggested that diabetics had 1.8 times more risk of having low high density lipoprotein cholesterol. Conclusions: Diabetic females over 45 years of age have significantly high chances of having disturbed or high lipid profile. Policy message:All persons in general and diabetics in particular over the age of 45 years should be screened for dyslipidemia and informed using behavior change communication to prevent disease complications.

  10. Effects of high levels of glucose on the steroidogenesis and the expression of adiponectin receptors in rat ovarian cells

    Ramé Christelle

    2008-03-01

    Full Text Available Abstract Background Reproductive dysfunction in the diabetic female rat is associated with altered folliculogenesis and steroidogenesis. However, the molecular mechanisms involved in the reduction of steroid production have not been described. Adiponectin is an adipocytokine that has insulin-sensitizing actions including stimulation of glucose uptake in muscle and suppression of glucose production in liver. Adiponectin acts via two receptor isoforms – AdipoR1 and AdipoR2 – that are regulated by hyperglycaemia and hyperinsulinaemia in liver and muscle. We have recently identified AdipoR1 and AdipoR2 in rat ovary. However, their regulation in ovaries of diabetic female rat remains to be elucidated. Methods We incubated rat primary granulosa cells in vitro with high concentrations of glucose (5 or 10 g/l + or - FSH (10-8 M or IGF-1 (10-8 M, and we studied the ovaries of streptozotocin-induced diabetic rats (STZ in vivo. The levels of oestradiol and progesterone in culture medium and serum were measured by RIA. We used immunoblotting to assay key steroidogenesis factors (3beta HSD, p450scc, p450 aromatase, StAR, and adiponectin receptors and various elements of signalling pathways (MAPK ERK1/2 and AMPK in vivo and in vitro. We also determined cell proliferation by [3H] thymidine incorporation. Results Glucose (5 or 10 g/l impaired the in vitro production in rat granulosa cells of both progesterone and oestradiol in the basal state and in response to FSH and IGF-1 without affecting cell proliferation and viability. This was associated with substantial reductions in the amounts of 3beta HSD, p450scc, p450 aromatase and StAR proteins and MAPK ERK1/2 phosphorylation. In contrast, glucose did not affect the abundance of AdipoR1 or AdipoR2 proteins. In vivo, as expected, STZ treatment of rats caused hyperglycaemia and insulin, adiponectin and resistin deficiencies. Plasma progesterone and oestradiol levels were also reduced in STZ rats. However, the

    2005-01-01

    Objective: To study the changes of levels of serum cortisol and gastrin in dogs with vibration-induced injury for providing better treatment regimen. Methods: In this experiment, 8 or 10 domestic dogs were placed on each of four sites away from explosion center about 0, 100, 200, 300 meters respectively. The dogs were standing uncontrolled or lying right side down under anesthesia. Serum cortisol and gastrin levels were detected with RIA both before and after explosion. Results: The levels of serum cortisol and gastrin began to fall about 24 hours after explosion. The serum levels of cortisol were still decreased significantly after 9 days and 17 days. Conclusion: The levels of the serum cortisol declined when the animals were injured by vibration. Detection of serum cortisol levels might lead to definitive diagnosis and supplemental treatment with cortical hormones for vibration-induced injury. (authors)

    2001-01-01

    Objective: To measure the serum leptin concentration in simple obese children together with other four kinds of related hormones. Methods: Serum Leptin, Ins, T 3 , T 4 and GH levels were measured by radioimmunoassay in thirty-eight obese children and thirty healthy controls. Results: The levels of serum leptin, Ins and T 3 in obese group were dramatically higher than those in control group (all P 4 concentration between simple obese children and control group (P > 0.05), Serum GH levels was significantly decreased in simple obese children (P < 0.01). There was a positive correlation between serum leptin levels and lns levels (r = 0.46, P < 0.01). Conclusion: In simple obese children there were leptin resistance and endocrine metabolic disturbances, the later might be correlated with the increasing of serum leptin levels; It is suggested that Leptin resistance might play a key role in the development of obesity

    2004-01-01

    Objective: To investigate the clinical significance of the changes of serum cortisol and insulin levels in neonates with asphyxia. Methods: Serum cortisol levels were determined with CLIA and serum insulin levels with RIA in 38 neonates with asphyxia (mild degree 20, advanced 18) and 30 controls. Results: 1) In mild cases, serum insulin levels were significantly higher than those in controls (p<0.01) and serum cortisol levels were very significantly higher (p<0.001). 2) In advanced cases, both serum insulin and cortisol levels were very significantly higher than those in the controls (p<0.001). Conclusion: Hypoxia in the neonates with asphyxia is a very severe stress and will induce hypersecretion of cortisol and hyperglycemia which is detrimental to the patients. However hypersecretion of insulin will result in hypoglycemia, which is also very damaging. Physicians in charge should be aware of these possibilities and deal with them appropriately

    2005-01-01

    Objective: To evaluate the relationship between serum levels of leptin and thyroid functional status. Methods: Serum leptin (with RIA) and pituitary-thyroid axis hormones (with CLIA) were measured in 75 euthyroid controls, 44 hyperthyroid subjects and 27 hypothyroid subjects. Results: The levels of leptin in euthyroid controls, hyperthyroid subjects and hypothyroid subjects were (5.40 ± 3.78) ng/ml, (5.99 ± 5.24) ng/ml and (5.59 ± 4.23) ng/ml respectively with no significant differences among them. The serum leptin levels were positively correlated with serum TSH levels (r=0.27, P<0.01). Conclusion: Thyroid function has no effect on serum leptin levels and TSH levels correlates closely with those of serum leptin. (authors)
