    Early prediction of disease severity of acute pancreatitis (AP) would be helpful for triaging patients to the appropriate level of care and intervention. The aim of the study was to develop a model able to predict Severe Acute Pancreatitis (SAP). A total of 647 patients with AP were enrolled. The demographic data, hematocrit, High-Density Lipoprotein Cholesterol (HDL-C) determinant at time of admission, Blood Urea Nitrogen (BUN), and serum creatinine (Scr) determinant at time of admission and 24 hrs after hospitalization were collected and analyzed statistically. Multivariate logistic regression indicated that HDL-C at admission and BUN and Scr at 24 hours (hrs) were independently associated with SAP. A logistic regression function (LR model) was developed to predict SAP as follows: -2.25-0.06 HDL-C (mg/dl) at admission + 0.06 BUN (mg/dl) at 24 hours + 0.66 Scr (mg/dl) at 24 hours. The optimism-corrected c-index for LR model was 0.832 after bootstrap validation. The area under the receiver operating characteristic curve for LR model for the prediction of SAP was 0.84. The LR model consists of HDL-C at admission and BUN and Scr at 24 hours, representing an additional tool to stratify patients at risk of SAP.

    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.

    With the increase of people"s living standard and the changes of living form, the number of people who suffer from hypercholesterolemia is increasing. It is not only harmful to heart and blood vessel, but also leading to obstruction of cognition. The conventional blood detection technology has weakness such as complex operation, long detecting period, and bad visibility. In order to develop a new detection method that can checkout hypercholesterolemia conveniently, spectroscopy of cholesterol in hypercholesterolemia serum is obtained by the multifunctional grating spectrograph. The experiment results indicate that, under the excitation of light-emitting diode (LED) with the wavelength at 407 nm, the serum from normal human and the hypercholesterolemia serum emit different fluorescence spectra. The former can emit one fluorescence region with the peak locating at 516 nm while the latter can emit two more regions with peaks locating at 560 nm and 588 nm. Moreover, the fluorescence intensity of serum is non-linear increasing with the concentration of cholesterol increases when the concentration of cholesterol is lower than 13.8 mmol/L, and then, with the concentration of cholesterol increase, the fluorescence intensity decreases. However, the fluorescence intensity is still much higher than that of serum from normal human. Conclusions can be educed from the experiments: the intensity and the shape of fluorescence spectra of hypercholesterolemia serum are different of those of normal serum, from which the cholesterol abnormal in blood can be judged. The consequences in this paper may offer an experimental reference for the diagnosis of the hypercholesterolemia.

    Garlic has been shown to have cardiovascular protective and immunomodulatory properties. We updated a previous meta-analysis on the effect of garlic on blood pressure and reviewed the effect of garlic on cholesterol and immunity. We searched the Medline database for randomized controlled trials (RCTs) published between 1955 and December 2013 on the effect of garlic preparations on blood pressure. In addition, we reviewed the effect of garlic on cholesterol and immunity. Our updated meta-analysis on the effect of garlic on blood pressure, which included 20 trials with 970 participants, showed a mean ± SE decrease in systolic blood pressure (SBP) of 5.1 ± 2.2 mm Hg (P garlic on blood lipids, which included 39 primary RCTs and 2300 adults treated for a minimum of 2 wk, suggested garlic to be effective in reducing total and LDL cholesterol by 10% if taken for >2 mo by individuals with slightly elevated concentrations [e.g., total cholesterol >200 mg/dL (>5.5 mmol/L)]. Garlic has immunomodulating effects by increasing macrophage activity, natural killer cells, and the production of T and B cells. Clinical trials have shown garlic to significantly reduce the number, duration, and severity of upper respiratory infections. Our review suggests that garlic supplements have the potential to lower blood pressure in hypertensive individuals, to regulate slightly elevated cholesterol concentrations, and to stimulate the immune system. Garlic supplements are highly tolerated and may be considered as a complementary treatment option for hypertension, slightly elevated cholesterol, and stimulation of immunity. Future long-term trials are needed to elucidate the effect of garlic on cardiovascular morbidity and mortality. © 2016 American Society for Nutrition.

    Full Text Available Low concentration of plasma lipoproteins (hypolipoproteinemia presents decreasing concentrations of all or particular lipids components. Classification of hypolipoproteinemia (hypoLP divides them into: primary (hereditary and secondary. Primary hipoLP are rare diseases and their main characteristic is disorder of apolipoproteins synthesis, which leads to low serum cholesterol concentration. Secondary hipoLP are presented in many diseases. They have diagnostic, prognostic significance and present good therapeutic marker. However, modern therapeutic approaches for aggressive lipid lowering pointed out many questions about physiological limits for cholesterol lowering. These approaches, also, open many questions about consequences of low serum concentration of total cholesterol and triglicerides.

    The efficacy and safety of plant stanols added to food products as serum cholesterol lowering agents have been demonstrated convincingly, but their effects on cholesterol metabolism and on serum non-cholesterol sterols is less evaluated. The aim of this study was to assess the validity of serum non-cholesterol sterols and squalene as bioindices of cholesterol synthesis and absorption, and to examine how the individual serum non-cholesterol sterols respond to consumption of plant stanols. We collected all randomized, controlled plant stanol ester (STAEST) interventions in which serum cholestanol, plant sterols campesterol and sitosterol, and at least two serum cholesterol precursors had been analysed. According to these criteria, there was a total of 13 studies (total 868 subjects without lipid-lowering medication; plant stanol doses varied from 0.8 to 8.8 g/d added in esterified form; the duration of the studies varied from 4 to 52 weeks). Serum non-cholesterol sterols were assayed with gas-liquid chromatography, cholesterol synthesis with the sterol balance technique, and fractional cholesterol absorption with the dual continuous isotope feeding method. The results demonstrated that during the control and the STAEST periods, the serum plant sterol/cholesterol- and the cholestanol/cholesterol-ratios reflected fractional cholesterol absorption, and the precursor sterol/cholesterol-ratios reflected cholesterol synthesis. Plant sterol levels were dose-dependently reduced by STAEST so that 2 g of plant stanols reduced serum campesterol/cholesterol-ratio on average by 32%. Serum cholestanol/cholesterol-ratio was reduced less frequently than those of the plant sterols by STAEST, and the cholesterol precursor sterol ratios did not change consistently in the individual studies emphasizing the importance of monitoring more than one surrogate serum marker. Serum non-cholesterol sterols are valid markers of cholesterol absorption and synthesis even during cholesterol

    The importance of leisure time physical activity as a health indicator became more obvious after the results of large prospective studies were published. The validity of these results depends upon both the selection of the active individuals and to what extent self-reported physical activity reflects the individual's true activity. The purpose of this paper is to describe the changes in self-reported physical activity, and to assess the relation between this variable and other biological risk factors such as blood lipids, blood pressure and body mass index (BMI). This report also aims at corroborating the validity of self-reported physical activity by assessing the consistency of the associations between these biological risk factors and physical activity during a 25-years period. The basis for this analysis is a long lasting observational study with a questionnaire as the most important research instrument, in addition to physiological and biological factors such as BMI, blood pressure and blood lipids. The study population consists of 332,182 individuals, aged 40-42 from different counties in Norway who were invited to participate in health survey during 1974-1999. The objectives of this study are (1) to describe changes in self-reported physical activity from 1974 to 1999; (2) to assess the relation between physical activity and the biological variables; and (3) to corroborate the validity of the variable physical activity by assessing the consistency of the above analysis. The results of the analyses of association between decade of birth and self-reported physical activity show that physical activity among 40-aged individuals decreased during 1974-1999. This trend is stronger among the men. Multivariate analyses revealed differences in BMI and serum cholesterol between levels of self-reported physical activity, gender, smoking habits and decade of birth. The explained percentage of the total variance ranged from 6% for BMI to 7% for serum cholesterol. The

    Full Text Available Clinical cases of vitamin E deficiencies have been diagnosed in camelids and may indicate that these species are more sensitive to inadequate vitamin E in hay-based diets compared to other ruminant and equine species. In bovine, cholesterol has been reported to affect vitamin E concentrations. In order to evaluate vitamin E deficiencies in camelids, the effects of collection and storage of the blood samples prior to processing were necessary. Reports vary as to factors affecting vitamin E and cholesterol in blood samples, and diagnostic laboratories vary in instructions regarding sample handling. Blood was collected from healthy alpacas and processed under conditions including exposure to fluorescent light, serum and red blood cell contact, tube stopper contact, temperature, and hemolysis. Serum vitamin E and cholesterol concentrations were then measured. Statistical analyses found that the vitamin E concentrations decreased with prolonged contact with the tube stopper and with increasing hemolysis. Vitamin E concentration variations were seen with other factors but were not significant. Time prior to serum separation and individual animal variation was found to alter cholesterol concentrations within the sample, yet this finding was clinically unremarkable. No correlation was seen between vitamin E and cholesterol concentration, possibly due to lack of variation of cholesterol.

    Full Text Available Introduction: High plasma cholesterol levels, mainly LDL are a widely recognized major risk factor for Coronary Heart Disease (CHD. According to the epidemiologic studies findings, people from the Mediterranean countries, have lower CHD rats than other countries, in these countries usual diet is high in olive oil. The present study compares the effects of cholesterol enriched diet with or without adding olive oil on serum Lipoproteins, lipid per oxidation, and atherosclerosis development. Method: Twenty Dutch male rabbits were Categorized to four groups (one group as Control, and others as Experimental. They received one of standard, cholesterol - rich, olive oil rich and combined (cholesterol + olive oil diet for Twelve weeks. Fasting blood samples from heart were collected at the beginning, and the end of Experimental period. Means of total cholesterol, HDL-Ctriglycerides, MDA and antioxidant caperimental period, significant differences were showed in total cholesterol, HDL-C, triglyceride and MDA between groups. Results: The comparison of cholesterol rich diet with cholesterol + olive oil showed a higher mean of MDA in cholesterol rich group (P < 0.001. Biochemical factors and aortic lesion degree showed no significant difference between standard and olive oil group. Aortic lesions in cholesterol + olive oil showed nonsignificant lower degree than cholesterol group. Discussion: This findings showed preventive effect of olive oil against atherosclerosis which is independent of plasma lipoprotein effect, and suggested that probably olive oil acts on arteries directly.

    More than one-half of coronary artery disease (CAD) patients have low HDL cholesterol despite having well-managed LDL cholesterol. Almond supplementation has not been shown to elevate circulating HDL cholesterol concentrations in clinical trials, perhaps because the baseline HDL cholesterol of trial subjects was not low. This clinical trial was designed to test the effect of almond supplementation on low HDL cholesterol in CAD patients. A total of 150 CAD patients (50 per group), with serum LDL cholesterol ≤100 mg/dL and HDL cholesterol ≤40 mg/dL in men and ≤50 mg/dL in women, were recruited from the Aga Khan University Hospital. After recording vital signs and completing a dietary and physical activity questionnaire, patients were randomly assigned to 1 of the following 3 groups: the no-intervention group (NI), the Pakistani almonds group (PA), and the American almonds group (AA). The respective almond varieties (10 g/d) were given to patients with instructions to soak them overnight, remove the skin, and eat them before breakfast. Blood samples for lipid profiling, body weight, and blood pressure were collected, and assessment of dietary patterns was done at baseline, week 6, and week 12. Almonds significantly increased HDL cholesterol. At weeks 6 and 12, HDL cholesterol was 12-14% and 14-16% higher, respectively, in the PA and AA than their respective baselines. In line with previous reports, serum concentrations of total cholesterol, triglycerides, LDL cholesterol, and VLDL cholesterol; total-to-HDL and LDL-to-HDL cholesterol ratios, and the atherogenic index were reduced in both the PA and AA at weeks 6 and 12 compared with baseline (P almond groups. Dietary patterns, body weight, and blood pressure did not change in any of the 3 groups during the trial. A low dose of almonds (10 g/d) consumed before breakfast can increase HDL cholesterol, in addition to improving other markers of abnormal lipid metabolism in CAD patients with low initial HDL cholesterol

    Background: Perfluorooctane sulfonate (PFOS) and perfluorooctanoic acid (PFOA) have consistently been associated with higher cholesterol levels in cross sectional studies. Concerns have, however, been raised about potential confounding by diet and clinical relevance. Objective: To examine the association between concentrations of PFOS and PFOA and total cholesterol in serum during pregnancy taking into considerations confounding by diet. Methods: 854 Danish women who gave birth in 1988–89 and provided a blood sample and reported their diet in week 30 of gestation. Results: Mean serum PFOS, PFOA and total cholesterol concentrations were 22.3 ng/mL, 4.1 ng/mL and 7.3 mmol/L, respectively. Maternal diet was a significant predictor of serum PFOS and PFOA concentrations. In particular intake of meat and meat products was positively associated while intake of vegetables was inversely associated (P for trend <0.01) with relative difference between the highest and lowest quartile in PFOS and PFOA concentrations ranging between 6% and 25% of mean values. After adjustment for dietary factors both PFOA and PFOS were positively and similarly associated with serum cholesterol (P for trend ≤0.01). For example, the mean increase in serum cholesterol was 0.39 mmol/L (95%CI: 0.09, 0.68) when comparing women in the highest to lowest quintile of PFOA concentrations. In comparison the mean increase in serum cholesterol was 0.61 mmol/L (95%CI: 0.17, 1.05) when comparing women in the highest to lowest quintile of saturated fat intake. Conclusion: In this study associations between PFOS and PFOA with serum cholesterol appeared unrelated to dietary intake and were similar in magnitude as the associations between saturated fat intake and serum cholesterol. - Highlights: • PFOS and PFOA have consistently been linked with raised serum cholesterol • Clinical relevance remains uncertain and confounding by diet has been suggested • The aim of this study was to address these issues in

    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.

    Cholesterol metabolism in blood erythrocytes and lymphocytes of irradiated rats has been investigated. It has been found that at all terms and doses of irradiation, a suppression of the synthesis of erythrocyte cholesterol is observed. The increase of cholesterol quantiy in erythrocytes upon total gamma irradiation in the 10 Gr dose possibly is the result of growth of cholesterol transfer from plasma into erythrocyte cells. The study of the cholesterol synthesis in suspension of lymphocytes elminated from peripheral blood of control and irradiated rats has shown that at irradiation doses of 4 and 10 Gr in an hour acivation of cholesterol synthesis in vitro takes places

    This study investigated the effect of coconut flakes on serum cholesterol levels of humans with moderately raised serum cholesterol in 21 subjects. The serum total cholesterol of subjects differed and ranged from 259 to 283 mg/dL. The study was conducted in a double-blind randomized crossover design on a 14-week period, consisting of four 2-week experimental periods, with each experimental period separated by a 2-week washout period. The test foods were as follows: corn flakes as the control food, oat bran flakes as the reference food, and corn flakes with 15% and 25% dietary fiber from coconut flakes (made from coconut flour production). Results showed a significant percent reduction in serum total and low-density lipoprotein (LDL) cholesterol (in mg/dL) for all test foods, except for corn flakes, as follows: oat bran flakes, 8.4 +/- 1.4 and 8.8 +/- 6.0, respectively; 15% coconut flakes, 6.9 +/- 1.1 and 11.0 +/- 4.0, respectively; and 25% coconut flakes, 10.8 +/- 1.3 and 9.2 +/- 5.4, respectively. Serum triglycerides were significantly reduced for all test foods: corn flakes, 14.5 +/- 6.3%; oat bran flakes, 22.7 +/- 2.9%; 15% coconut flakes, 19.3 +/- 5.7%; and 25% coconut flakes, 21.8 +/- 6.0%. Only 60% of the subjects were considered for serum triglycerides reduction (serum triglycerides >170 mg/dL). In conclusion, both 15% and 25% coconut flakes reduced serum total and LDL cholesterol and serum triglycerides of humans with moderately raised serum cholesterol levels. Coconut flour is a good source of both soluble and insoluble dietary fiber, and both types of fiber may have significant role in the reduction of the above lipid biomarker. To our knowledge, this is the first study conducted to show a relationship between dietary fiber from a coconut by-product and a lipid biomarker. Results from this study serves as a good basis in the development of coconut flakes/flour as a functional food, justifying the increased production of coconut and coconut by-products.

    Risk factors for osteoporotic fractures were evaluated in 1,396 men and women for a period of 20 years. Serum total cholesterol was found to be an independent osteoporotic fracture risk factor whose predictive power improves with time. The purpose of this study was to evaluate long-term risk factors for osteoporotic fracture. A population random sample of men and women aged 25-64 years (the Gothenburg WHO MONICA project, N = 1,396, 53% women) was studied prospectively. The 1985 baseline examination recorded physical activity at work and during leisure time, psychological stress, smoking habits, coffee consumption, BMI, waist/hip ratio, blood pressure, total, HDL and LDL cholesterol, triglycerides, and fibrinogen. Osteoporotic fractures over a period of 20 years were retrieved from the Gothenburg hospital registers. Poisson regression was used to analyze the predictive power for osteoporotic fracture of each risk factor. A total number of 258 osteoporotic fractures occurred in 143 participants (10.2%). As expected, we found that previous fracture, smoking, coffee consumption, and lower BMI each increase the risk for osteoporotic fracture independently of age and sex. More unexpectedly, we found that the gradient of risk of serum total cholesterol to predict osteoporotic fracture significantly increases over time (p = 0.0377). Serum total cholesterol is an independent osteoporotic fracture risk factor whose predictive power improves with time. High serum total cholesterol is a long-term cause of osteoporotic fracture.

    To study the whole-body cholesterol metabolism in man, cholesterol synthesis and absorption need to be measured. Because of the complicated methods of the measurements, new approaches were developed including the analysis of serum non-cholesterol sterols. In current lipidologic papers and even in intervention studies, serum non-cholesterol sterols are frequently used as surrogate markers of cholesterol metabolism without any validation to the absolute metabolic variables. The present review compares serum non-cholesterol sterols with absolute measurements of cholesterol synthesis and absorption in published papers to find out whether the serum markers are valid indicators of cholesterol metabolism in various conditions. During statin treatment, during interventions of dietary fat, and in type 2 diabetes the relative and absolute variables of cholesterol synthesis and absorption were frequently but not constantly correlated with each other. In some occasions, especially in subjects with apolipoprotein E3/4 and E4/4 phenotypes, the relative metabolic markers were even more sensitive than the absolute ones to reflect changes in cholesterol metabolism during dietary interventions. Even in general population at very high absorption the homeostasis of cholesterol metabolism is disturbed damaging the validity of the serum markers. It is worth using several instead of only one precursor and absorption sterol marker for making conclusions of altered synthesis or absorption of cholesterol, and even then the presence of at least some absolute measurement is valuable. During consumption of plant sterol-enriched diets and in situations of interfered cholesterol homeostasis the relative markers do not adequately reflect cholesterol metabolism. Accordingly, the validity of the relative markers of cholesterol metabolism should not be considered as self-evident. Copyright © 2011 Elsevier B.V. All rights reserved.

    1987-01-01

    We describe a new gas-chromatographic/mass-spectrometric (GC/MS) isotope-dilution method for determination of serum cholesterol. The method has been fully optimized and documented to provide the high accuracy and precision expected for a Definitive Method. In the presence of [3,4- 13 C]cholesterol, cholesteryl esters in serum are hydrolyzed under optimum conditions and the entire cholesterol pool is extracted and derivatized to silyl ethers. The cholesterol derivatives are resolved from other sterols by gas-liquid chromatography on a fused silica column, and selected ions characteristic of cholesterol and the [3,4- 13 C]cholesterol are monitored with a GC/MS quandrupole system. We estimated the cholesterol content of samples by bracketing each sample with standards of comparable cholesterol concentration that also contained the [3,4- 13 C]cholesterol. The procedure was highly reproducible (CV less than 0.5%), better accuracy and precision being obtained with [3,4- 13 C]cholesterol than with heptadeuterated cholesterol. Mean values per gram of dry serum for one serum pool assayed by this method and that of the National Bureau of Standards differed by 0.5%. We conclude that the method satisfies the criteria for a Definitive Method

  12. Transition diseases in grazing dairy cows are related to serum cholesterol and other analytes.

    Full Text Available The objectives of this study were to describe the incidence of postpartum disease and to evaluate the association with serum cholesterol concentrations during the first 3 weeks after calving in grazing dairy cows. The association between non-esterified fatty acids (NEFA, β-hydroxybutyrate (BHBA, calcium and postpartum diseases was also evaluated. A total of 307 Holstein dairy cows from 6 commercial grazing herds in Osorno, Chile, were monitored from calving until 21 days in milk. Cases of retained placenta, clinical hypocalcemia and clinical mastitis were recorded by the farmer using established definitions. Twice weekly, cows were evaluated for metritis by the same veterinarian based on vaginal discharge and body temperature. Postpartum blood samples were collected weekly and analyzed for serum concentrations of cholesterol, NEFA, BHBA and calcium. Cows were considered as having subclinical ketosis if BHBA >1.2 mmol/L, and subclinical hypocalcemia if calcium <2.0 mmol/L in any of the 3 weekly samples. Overall, 56% of the cows studied developed at least one clinical or subclinical disease after calving. Incidence of individual diseases was 8.8% for retained placenta, 4.2% for clinical hypocalcemia, 11.7% for clinical mastitis, 41.1% for metritis, 19.9% for subclinical hypocalcemia and 16.6% for subclinical ketosis. Lower postpartum cholesterol in cows was associated with developing severe metritis or having more than one clinical disease after calving. For every 0.4 mmol/L decrease in serum cholesterol cows were nearly twice as likely to be diagnosed with multiple clinical diseases after calving. Higher BHBA concentrations and lower calcium concentrations during week 1 were associated with severe cases of metritis. Low serum calcium concentration during week 1 was also associated with developing more than one clinical disorder after calving. In conclusion, the incidence of postpartum diseases can be high even in grazing herds and lower serum

    Blood testing for endogenous small metabolites to determine physiological and biochemical states is routine for laboratory analysis. Here we demonstrate that by combining the commercial direct analysis in real time (DART) ion source with an ion trap mass spectrometer, native cholesterol in its free alcohol form is readily detected from a few hundred nanoliters of human serum loaded onto chromatography paper. Deuterium-labeled cholesterol was used as the internal standard to obtain the absolute quantity of the endogenous cholesterol. The amount of the cholesterol measured by this paper-loaded DART mass spectrometry (pDART-MS) is statistically comparable with that obtained by using commercially available fluorometric-enzymatic assay and liquid chromatography/mass spectrometry. Furthermore, sera from 21 participants at three different time points in an ultramarathon were collected to obtain their cholesterol levels. The test requires only very minimal sample preparation, and the concentrations of cholesterol in each sample were acquired within a minute.

    Full Text Available In order to compare cholesterol contents in cow and camel milk in similar farming conditions, milk and blood of seven cows and seven camels maintained at normal diet at the middle of lactation were sampled at morning and evening, then after two weeks of keeping them at low protein diet. The cholesterol content in camel milk (5.64 ± 3.18 mg/100 g, SD was not significantly lower than in cow milk (8.51 ± 9.07 mg/100 g, SD. Fat contents in cow milk were higher. Cholesterol/fat ratios were similar in the two species (camel: 225 ± 125 mg/100 g fat; cow: 211 ± 142 mg/100 g fat. The serum cholesterol concentration was significantly higher in cow (227.8 ± 60.5 mg/100 ml than in camel (106.4 ± 28.9 mg/100 ml. There was a significant difference between morning and evening milking in milk fat compositions and concentrations in cholesterol. Fat levels increased in cow after two-week low energy-protein diet.

    Detection of blood cholesterol is of great clinical significance. The amperometric detection technique was used for the enzymatic assay of total cholesterol. Multiwall carbon nanotubes (MWNTs), vertically aligned on a silicon platform, promote heterogeneous electron transfer between the enzyme and the working electrode. Surface modification of the MWNT with a biocompatible polymer, polyvinyl alcohol (PVA), converted the hydrophobic nanotube surface into a highly hydrophilic one, which facilitates efficient attachment of biomolecules. The fabricated working electrodes showed a linear relationship between cholesterol concentration and the output signal. The efficacy of the multiwall carbon nanotubes in promoting heterogeneous electron transfer was evident by distinct electrochemical peaks and higher signal-to-noise ratio as compared to the Au electrode with identical enzyme immobilization protocol. The selectivity of the cholesterol sensor in the presence of common interferents present in human blood, e.g. uric acid, ascorbic acid and glucose, is also reported.

    Full Text Available Chitosan treatment results in significantly lower serum low density lipoprotein (LDL cholesterol concentrations. To assess the working mechanisms of chitosan, we measured serum surrogate markers of cholesterol absorption (campesterol, sitosterol, cholestanol, synthesis (lathosterol, lanosterol, desmosterol, and degradation to bile acids (7α-hydroxy-cholesterol, 27-hydroxy-cholesterol, corrected for cholesterol concentration (R_sterols. Over 12 weeks, 116 obese subjects (Body Mass Index, BMI 31.7, range 28.1–38.9 kg/m2 were studied under chitosan (n = 61 and placebo treatments (n = 55. The participants were briefly educated regarding improvement of nutrition quality and energy expenditure. Daily chitosan intake was 3200 mg. Serum LDL cholesterol concentration decreased significantly more (p = 0.0252 under chitosan (−8.67 ± 18.18 mg/dL, 5.6% than under placebo treatment (−1.00 ± 24.22 mg/dL, 0.9%. This reduction was not associated with the expected greater decreases in markers of cholesterol absorption under chitosan treatment. Also, increases in markers of cholesterol synthesis and bile acid synthesis under chitosan treatment were not any greater than under placebo treatment. In conclusion, a significant selective reduction of serum LDL cholesterol under chitosan treatment is neither associated with a reduction of serum surrogate markers of cholesterol absorption, nor with increases of markers for cholesterol and bile acid synthesis.

    Evidence from clinical studies has suggested that cocoa may increase high-density lipoprotein (HDL)-cholesterol concentrations. However, it is unclear whether this effect is attributable to flavonoids or theobromine, both of which are major cocoa components. We investigated whether pure theobromine increases serum HDL cholesterol and whether there is an interaction effect between theobromine and cocoa. The study had a 2-center, double-blind, randomized, placebo-controlled, full factorial parallel design. After a 2-wk run-in period, 152 healthy men and women (aged 40-70 y) were randomly allocated to consume one 200-mL drink/d for 4 wk that contained 1) cocoa, which naturally provided 150 mg theobromine and 325 mg flavonoids [cocoa intervention (CC)], 2) 850 mg pure theobromine [theobromine intervention (TB)], 3) cocoa and added theobromine, which provided 1000 mg theobromine and 325 mg flavonoids [theobromine and cocoa intervention (TB+CC)], or 4) neither cocoa nor theobromine (placebo). Blood lipids and apolipoproteins were measured at the start and end of interventions. In a 2-factor analysis, there was a significant main effect of the TB (P cocoa and interaction effects suggested that theobromine may be the main ingredient responsible for the HDL cholesterol-raising effect. This trial was registered at clinicaltrials.gov as NCT01481389.

    1993-06-01

    An educational program for persons found to have high blood cholesterol during health examinations at the Nerima Public Health Center was begun in April, 1989. This program was differed from the usual program in two areas. First, new educational material was developed consisting of a check list of 30 items to assess eating patterns. By checking these items, participants could gain an understanding of what they should change in their eating behavior. Secondly, the table of restricted foods was not used. Participants were advised to achieve healthy eating patterns and followed up with a nutritional consultation that was held after three months, at which time they were interviewed regarding compliance and had their blood cholesterol levels measured. The effectiveness of the new educational program and the relationship between achievement of healthy eating patterns and reduction in blood cholesterol levels were analyzed. The main results were as follows: 1) In subjects (n = 79) who received the new education program in 1989-1990, serum cholesterol levels showed significant reduction, as compared with controls (n = 38) who received the usual education program in 1988-1989. 2) Subjects were divided into three groups according to their changes in serum cholesterol levels,--normalized, improved and unimproved--and the number of items complied with were counted for analysis. The mean score of compliance was highest in the normalized group with significant difference between the normalized and the unimproved groups. 3) The items of the high compliance score in the normalized group were in order of high score "to decrease high-fat meats", "to decrease cakes", "to choose lean meats and poultry without skin" and "to eat vegetables at every meal".

    We describe an accurate, precise method for determination of total serum cholesterol by isotope dilution/mass spectrometry (IDMS) with liquid chromatographic separation. After adding [3,4- 13 C] cholesterol to serum and hydrolyzing the cholesterol esters, we extract the total cholesterol. High-performance liquid chromatography (HPLC) is used to separate the extracted cholesterol for measurement by electron-impact mass spectrometry with use of a direct-insertion device. To evaluate the specificity and the accuracy of this method, we also studied the conventional IDMS method, which involves converting cholesterol to the trimethylsilyl ether and assay by gas chromatography-mass spectrometry with use of a capillary column. The coefficient of variation for the HPLC method was a little larger than for the conventional method, but mean values by each method agreed within 1% for all sera tested. (author)

    Background: Oral garlic supplementation may be effective in decreasing serum cholesterol levels as much as 15% to 20%. Garlic indirectly effect atherosclerosis by reduction of hyperlipidaemia, hypertension and probably diabetes mellitus and prevents thrombus formation. This study was undertaken to test the hypothesis that garlic powder with a prolonged mode of action promises potent biological effects into hypercholesterolaemia. Methods: Fifty albino rats were randomly divided into 5 equal groups (n=10). All rats were initially fed normal diet for at least 7 days. Then Group A was control and was fed a normal diet + 0.5% cholesterol, Group B was fed normal diet and 3 mg garlic per 10 g of feed and Group C was fed normal diet and 10 mg garlic per 10 g of feed. The experiment lasted for 12 weeks. Body weight and serum cholesterol were noted before and after giving garlic + cholesterol. Results: Effect of serum cholesterol level was significantly decreased after taking 3 and 10 mg of garlic. However it was observed that the body weight was increased after taking garlic. Conclusion: Garlic consumption although can decrease the level of serum cholesterol but it increases the body weight. Garlic consumption alone can decrease serum cholesterol level, but it cannot be used as the main therapeutic agent for hyperlipidaemia. (author)

    Coronary heart disease (CHD) is an abnormal narrowing of heart arteries associated with local accumulation of lipids, in the form of cholesterol and triglycerides. Periodontal disease is a chronic inflammatory that suggests link to the development of CHD. In periodontitis have been reported changes in lipid profile, include increased of cholesterol levels of blood. Objective: to analyse correlation between blood cholesterol level with periodontal status of CHD and non CHD subjects. Methods: Periodontal status and blood cholesterol level of 60 CHD and 40 non CHD subjects was measured. Result: Blood cholesterol level in CHD subjects differs from non CHD subjects (p=0.032). Blood cholesterol level correlates with pocket depth (p=0.003) and clinical attachment loss (CAL) (p=0.000) in CHD subjects. Blood cholesterol level correlates with pocket depth (p=0.010) in non CHD subjects. There is no significant correlation between blood cholesterol level and bleeding on probing (BOP) in CHD subjects. There is no significant correlation between blood cholesterol level with BOP and CAL in non CHD subjects. Conclusion: Blood cholesterol level in control group is higher than CHD patients. Blood cholesterol level positively associated with pocket depth (r=0.375) and CAL (r=0.450) in CHD patients. Blood cholesterol level is positively associated with pocket depth (r=0.404) in control group.

    Blood triacylglycerol (TG) and lipoproteins are important variables for evaluating nutritional status of wildlife, but measurements are often expensive and difficult. Performance of a small, portable blood analyzer intended for human medical diagnostics was evaluated in measuring these variables in plasma and serum from free-ranging polar bears (Ursus maritimus), which are experiencing nutritional stress related to sea ice loss. The analyzer accurately tracked changes in concentration of total cholesterol (Ctotal), cholesterol associated with high-density lipoprotein (CHDL), and TG during a validation protocol of diluting samples and spiking them with exogenous cholesterol and glycerol. Values of Ctotal and TG agreed well with values obtained by other methods (ultracentrifugation followed by colorimetric assays); agreement was variable for values of cholesterol associated with specific lipoproteins. Similar to a study of captive polar bears, ultracentrifugation methods revealed greater TG in very low-density lipoproteins than in low-density lipoprotein, which is unusual and merits additional study.

    Long-term exposure to di-(2-ethylhexyl) phthalate (DEHP) is highly associated with carcinogenicity, fetotoxicity, psychological disorders and metabolic diseases, but the detrimental effects and mechanisms are not fully understood. We investigated the effect of exposing mouse mothers to DEHP, and the underlying mechanism, on blood pressure, obesity and cholesterol metabolism as well as psychological and learning behaviors in offspring. Tail-cuff plethysmography was used for blood pressure measurement; Western blot used was for phosphorylation and expression of protein; hematoxylin and eosin staining, Nissl staining and Golgi staining were used for histological examination. The serum levels of cholesterol, triglycerides and glucose were measured by blood biochemical analysis. Hepatic cholesterol and triglyceride levels were assessed by colorimetric assay kits. Offspring behaviors were evaluated by open-field activity, elevated plus maze, social preference test and Morris water maze. Maternal DEHP exposure deregulated the phosphorylation of endothelial nitric oxide synthase and upregulated angiotensin type 1 receptor in offspring, which led to increased blood pressure. It led to obesity in offspring by increasing the size of adipocytes in white adipose tissue and number of adipocytes in brown adipose tissue. It increased the serum level of cholesterol in offspring by decreasing the hepatic capacity for cholesterol clearance. The impaired social interaction ability induced by maternal DEHP exposure might be due to abnormal neuronal development. Collectively, our findings provide new evidence that maternal exposure to DEHP has a lasting effect on the physiological functions of the vascular system, adipose tissue and nerve system in offspring.

    Full Text Available Indonesians have a high intake of saturated fats, a key contributing dietary factor to elevated blood cholesterol concentrations. We investigated the cholesterol lowering efficacy of a smoothie drink with 2 grams of plant stanols as esters to lower serum total and LDL-cholesterol concentrations in hypercholesterolemic Indonesian adults. The double-blind randomized placebo controlled parallel design study involved 99 subjects. Fifty subjects received control drink and dietary advice, and 49 subjects received intervention drink (Nutrive Benecol® and dietary advice. Baseline, midline (week 2, and endline (week 4 assessments were undertaken for clinical, anthropometric, and biochemical variables. Compared to control, the smoothie drink with plant stanols reduced serum LDL-cholesterol concentration by 7.6% (p<0.05 and 9.0% (p<0.05 in two and four weeks, respectively. Serum total cholesterol was reduced by 5.7% (p<0.05 compared to control in two weeks, and no further reduction was detected after four weeks (5.6%. Compared to baseline habitual diet, LDL-cholesterol was reduced by 9.3% (p<0.05 and 9.8% (p<0.05 in the plant stanol ester group in two and four weeks, respectively. We conclude that consumption of smoothie drink with added plant stanol esters effectively reduces serum total and LDL-cholesterol of hypercholesterolemic Indonesian subjects already in two weeks. Trial is registered as NCT02316808.

    Full Text Available Abstract Background Soluble fibers lower serum lipids, but are difficult to incorporate into products acceptable to consumers. We investigated the physiological effects of a concentrated oat β-glucan on cardiovascular disease (CVD endpoints in human subjects. We also compared the fermentability of concentrated oat β-glucan with inulin and guar gum in a model intestinal fermentation system. Methods Seventy-five hypercholesterolemic men and women were randomly assigned to one of two treatments: 6 grams/day concentrated oat β-glucan or 6 grams/day dextrose (control. Fasting blood samples were collected at baseline, week 3, and week 6 and analyzed for total cholesterol, HDL cholesterol, LDL cholesterol, triglycerides, glucose, insulin, homocysteine and C-reactive protein (CRP. To estimate colonic fermentability, 0.5 g concentrated oat β-glucan was incubated in a batch model intestinal fermentation system, using human fecal inoculum to provide representative microflora. Fecal donors were not involved with the β-glucan feeding trial. Inulin and guar gum were also incubated in separate serum bottles for comparison. Results Oat β-glucan produced significant reduction from baseline in total cholesterol (-0.3 ± 0.1 mmol/L and LDL cholesterol (-0.3 ± 0.1 mmol/L, and the reduction in LDL cholesterol were significantly greater than in the control group (p = 0.03. Concentrated oat β-glucan was a fermentable fiber and produced total SCFA and acetate concentrations similar to inulin and guar gum. Concentrated oat β-glucan produced the highest concentrations of butyrate at 4, 8, and 12 hours. Conclusion Six grams concentrated oat β-glucan per day for six weeks significantly reduced total and LDL cholesterol in subjects with elevated cholesterol, and the LDL cholesterol reduction was greater than the change in the control group. Based on a model intestinal fermentation, this oat β-glucan was fermentable, producing higher amounts of butyrate than other

    Cholesterol is one of the most frequently measured substances in human blood/serum to assist in assessing the health status of individuals. Because of its clinical significance, CCQM-K6 determination of cholesterol in serum was completed in 2000 as one of the first key comparison (KC) studies performed within the Organic Analysis Working Group (OAWG). The first subsequent KC for cholesterol, CCQM-K6.1, was completed in 2001. Measurements for this second subsequent, CCQM-K6.2, were completed in 2012. These subsequent comparisons were conducted to enable CCQM members that had not participated in earlier studies to demonstrate their capabilities to measure a nonpolar (pKow mass (100 g/mol to 500 g/mol) metabolite in human serum at relatively high concentrations (1 mg/g to 3 mg/g) found in normal populations. Successful participation in CCQM-K6.2 demonstrated capabilities in analysis of complex biological matrices including sample preparation (extraction, derivatization), LC or GC separation, and quantification using an isotope dilution mass spectrometry approach. Normally in a subsequent KC, no key comparison reference value (KCRV) would be established and assessment of performance would be via the deviation of participants' results to the anchor institute's results, adjusted to account for the anchor's performance in the original comparison versus its KCRV. Due to the very long-time period since the original key comparison, the OAWG decided that this did not represent the best approach to assess performance in what is a relatively complex measurement. Given the excellent agreement between the anchor institute's results and robust consensus summary of the participants' values, the reference value for this study was taken as the anchor institute's result and treated as a 'KCRV'. Seven of the nine participants demonstrated agreement with the reference value. Main text To reach the main text of this paper, click on Final Report. Note that this text is that which appears

    2011-09-01

    Full Text Available Introduction: High low-density lipoproteins (LDL cholesterol is one of the major risk factors for cardiovascular disease. In recent years, some evidence has been presented that periodontitis,an infectious inflammatory condition of the periodontium, is associated with an increased risk of cardiovascular disease. To further elucidate this association, we have studied the levels of LDL cholesterol, a known risk marker for cardiovascular disease, in a periodontally-diseased group. Methods: The levels of serum LDL cholesterol in 47 subjects with mild to severe (clinical attachment loss equal to or greater than 1 mm chronic generalized (at least 30% of teeth affected periodontitis with the mean age of 42.21 ± 1.46 years were measured and compared with those obtained from 42 age (39.83 ± 0.94 and sex matched controls. Both groups were free from systemic illnesses. Results: The mean serum LDL cholesterol in periodontitis patients was found to be signifi cantly higher (P < 0.001 as compared to that of the controls. The mean clinical attachment loss was positively correlated with serum LDL cholesterol (P < 0.01 and gingival index (P<0.05. The frequency of persons with pathologic values of LDL cholesterol was signifi cantly higher in periodontitis patients compared with that of the controls. Conclusions: These results showed that high serum LDL cholesterol may be associated with periodontitis in healthy people. However, it is unclear whether periodontitis causes an increase in the levels of serum LDL or an increased LDL is a risk factor for both periodontitis and cardiovascular disease. Keywords: Cardiovascular disease, LDL cholesterol, periodontitis.

    Full Text Available Depression is a state of sadness, hopelessness, and discouragement. Various studies have been conducted to uncover the etiological factors involved in depression. Serum folic acid is one such factor. Many researchers have reported an inverse association between serum folic acid and depression. We did an extensive computerized database searches on PubMed, Medline, and EBSCO and found that low serum folic acid are associated with depression, not only in adults, but also in elderly and diabetic patients. Further augmentation of folic acid with antidepressant treatment also improves the treatment outcome in depressed patients. Hence, considering the high benefits to the adverse effects ratio of serum folic acid, its supplementation should be done in "at risk" population whenever possible.

    To assess whether subclinical hypothyroidism is associated to elevations in serum cholesterol and triglyceride levels in patients with type 2 diabetes. From a total population of 1,112 patients with type 2 diabetes screened for thyroid dysfunction (thyrotropin measurement), a group of 325 patients with normal thyroid function and another group of 29 patients with subclinical hypothyroidism were selected. No patient had known dyslipidemia or was taking lipid lowering medication. Patients with subclinical hypothyroidism had serum levels of total cholesterol (4.88 ± 0.74 mmol/L), HDL cholesterol (1.37 ± 0.34 mmol/L), LDL cholesterol (2.94 ± 0.58 mmol/L), and triglycerides (1.05 [0.88-1.41] mmol/L) that did not significantly differ from those found in euthyroid patients (4.79 ± 0.83, 1.33 ± 0.36, 2.87 ± 0.76, and 1.11 [0.81-1.43] mmol/L, respectively). Multiple regression analysis showed no association between TSH and serum lipid levels. These results suggest that, in our population, there are no significant differences in serum cholesterol and triglyceride levels between diabetic patients with normal and reduced thyroid function.

    Full Text Available BACKGROUND: Soy milk (SM and its fermented products are identified as rich sources of bioactive compounds helping to manage and to reduce the risk of chronic disease. This study aimed to compare the effects of SM and probiotic SM (PSM consumption on serum low-density lipoprotein cholesterol (LDL-C and high-density lipoprotein cholesterol (HDL-C in diabetic Wistar rats. METHODS: Probiotic SM was prepared by fermentation of the plain SM with a native strain of Lactobacillus plantarum. 20 streptozotocin-nicotinamide-induced diabetic Wistar rats were divided into two groups based on the type of administered SM (SM group and PSM group. The animals were fed with 1 ml/day of either soy or PSM for 21 days. The serum lipoprotein levels were analyzed at baseline and the end of the intervention period. RESULTS: HDL-C increased significantly in PSM group. Furthermore, this group showed more percent of change in increased HDL-C in compression with SM group (P < 0.050. Regarding LDL-C level, rats fed with SM was not significantly different from the PSM group (P < 0.050; though, this biomarker was reduced in both group. CONCLUSION: Probiotic SM could modulate blood lipoprotein levels. Thus, it may be considered in managing diabetes complications and atherosclerotic risks.

    Full Text Available Abstract Background Reference data for plasma lipids and blood pressure are not available for Asian Indian adolescents. This study aimed to develop representative age- and sex- specific percentile reference data for serum lipids [total cholesterol (TC, triglycerides (TG, low density lipoprotein cholesterol (LDL-C, high density lipoprotein cholesterol (HDL-C, non-HDL cholesterol] and blood pressure for urban Asian Indian adolescents aged 14–18 years. The sample consisted of 680 boys and 521 girls aged 14–18 years from the cross-sectional population survey, Epidemiological Study of Adolescents and Young Adults (ESAY for whom the data for serum lipid levels and blood pressure were recorded. Smoothed age- and sex- specific 5th, 10th, 25th, 50th, 75th, 85th, 90th and 95th percentiles where derived using LMS regression. Results Percentile-based reference data for serum lipids and blood pressure are presented for adolescent Asian Indian boys and girls for the first time. Asian Indian adolescents had lower levels of serum TC, LDL-C and HDL-C and higher TG than their counterparts in the USA. Interesting trends in TC and HDL-C levels where observed, which might reflect changes in dietary pattern and physical activity in this age group in India. Conclusion These reference data could be used to identify adolescents with an elevated risk of developing dyslipidemia, hypertension and cardiovascular disorders, to plan and implement preventive policies, and to study temporal trends.

The activities of the enzymes gamma-glutamyl-transferase (GGT, aspartate aminotransferase (AST, creatine kinase (CK, alkaline phosphatase (ALP, and lactate dehydrogenase (LDH, serum levels of total calcium, calcium ion, phosphorus, sodium, potassium, magnesium, chlorides, creatinine, uric acid, triglycerides, cholesterol, total protein, albumin, total and indirect and direct bilirubin, and electrophoretic profile of serum proteins in acrylamide (SDS-PAGE and agarose gel were determined. There was no influence of age on total bilirubin and albumin levels. All the other evaluated parameters presented differences in at least one age group. Protein electrophoretic profile also changed as a function of age. The obtained results can be considered as normal for the studied ages, and therefore be used as references for the interpretation of laboratory exams of broilers of this genetic line in the evaluated ages.

    Cholesterol homeostasis is dependent upon the sterol regulatory element binding protein 2 (SREBP-2) regulatory system and the functioning of plasma proprotein convertase subtilisin/kexin type 9 (PCSK9). Many studies have also reported that low density lipoprotein receptor (LDLR) levels in cellular membranes are related to the functioning of these proteins. The aim of this study was to investigate the association of lipid profiles with circulating PCSK9 protein values and SREBP-2 expression levels in normal subjects. The study involved 120 randomly chosen healthy subjects. Their lipid profiles were measured using routine laboratory techniques, and the plasma PCSK9 protein and SREBP-2 expression levels were determined by ELISA and real time quantitative PCR methods, respectively. A statistical analysis was carried out using a statistical software package. Linear regression analyses showed a significant correlation between total cholesterol and PCSK9 (3.54 ± 1.31 ng/mL), as well as between total cholesterol and SREBP-2 (0.1-35.38) (p = 0.002 and p = 0.02, respectively). Furthermore, multiple regression analyses showed strict correlations between PCSK9 and cholesterol-related parameters especially the total cholesterol/HDL-C ratio (β = 3.53, p = 0.001). There was no significant correlation between circulating PCSK9 and SREBP-2 expression levels (r = 1.2, p = 0.3). The study results revealed that serum cholesterol-related parameters are strictly associated with plasma PCSK9 values, suggesting that PCSK9 function has a greater effect on serum total cholesterol levels than SREBP-2 expression does. Furthermore, the total cholesterol/HDL-C ratio was a better indicator for evaluating PCSK9 level than total cholesterol.

    Full Text Available Objectives. To compare the effects of moxibustion at two different temperatures (38°C and 46°C on the blood cholesterol level in a mice model of acute hyperlipidemia, to detect the different expression levels of transient receptor potential vanilloid subfamily 1 (TRPV1 in the dorsal root ganglions of the wild mice, and to explore the correlation between TRPV1 and moxibustion’s cholesterol-lowering effects. Method. Two different mice models were used: C57BL/6J wild type (WT and TRPV1 gene knockout (TRPV1−/−. Each model was randomly divided into control group and model group with three subgroups after acute hyperlipidemia was established: model control group, 38°C moxibustion group, and 46°C moxibustion group. The mice in 38°C group and 46°C group were subject to moxibustion. After the therapy, the cholesterol concentration in serum was measured, and the expression of TRPV1 was quantified. Results. In WT mice, moxibustion caused a decrease in blood cholesterol level and upregulation of TRPV1 at the mRNA level, which was significantly greater in the 46°C group. In contrast, in TRPV1−/− mice, the differences of cholesterol-lowering effects of moxibustion were lost. Conclusions. Temperature is one of the important factors affecting the effects of moxibustion, and the cholesterol -lowering effect of moxibustion is related to the activation of TRPV1.

    The effect of a single dose of whole body irradiation on the serum cholesterol content and fatty acid composition of serum lipids in rats was investigated. A change in the fatty acid composition of liver lipids was also observed. After 600 rad of irradiation, the cholesterol content increased, reached a maximum 3 days after irradiation, and then decreased. After irradiation, an increase in cholesterol content and a marked decrease in triglyceride content were observed, bringing about a change in the amount of total serum lipids. The fatty acid compositions of normal and irradiated rat sera were compared. The relative percentages of palmitic and oleic acids in total lipids decreased while those of stearic and arachidonic acids increased. Serum triglyceride had trace amounts of arachidonic acid and the unsaturated fatty acid component decreased after irradiation. On the other hand, unsaturated fatty acid in cholesterol ester increased after irradiation, while linoleic and arachidonic acids made up 29% and 22% in the controls and 17% and 61% after irradiation, respectively. The fatty acid composition of total liver lipids after irradiation showed a decrease in palmitic and oleic acids and an increase in stearic and arachidonic acids, the same trend as observed in serum lipid fatty acid. Liver cholesterol ester showed trace amounts of linoleic and arachidonic acids and an increase in short-chain fatty acid after irradiation. The major component of serum phospholipids was phosphatidylcholine while palmitostearyl lecithine and unsaturated fatty acid were minor components. Moreover, phosphatidylcholine and phosphatidylethanolamine were the major components of liver phospholipids, having highly unsaturated fatty acids. The changes in fatty acid composition were similar to the changes in total phospholipids. (J.P.N.)

    Background : Almonds may increase circulating HDL cholesterol when substituted for a high-carbohydrate snack in an isocaloric diet, yet little is known about the effects on HDL biology and function. Objective: The objective was to determine whether incorporating 43 g almonds/d in a cholesterol-lowering diet would improve HDL subspecies and function, which were secondary study outcomes. Methods: In a randomized, 2-period, crossover, controlled-feeding study, a diet with 43 g almonds/d (percentage of total energy: 51% carbohydrate, 16% protein, and 32% total and 8% saturated fat) was compared with a similar diet with an isocaloric muffin substitution (58% carbohydrate, 15% protein, and 26% total and 8% saturated fat) in men and women with elevated LDL cholesterol. Plasma HDL subspecies and cholesterol efflux from J774 macrophages to human serum were measured at baseline and after each diet period. Diet effects were examined in all participants ( n = 48) and in normal-weight (body mass index: almond diet, compared with the control diet, increased α-1 HDL [mean ± SEM: 26.7 ± 1.5 compared with 24.3 ± 1.3 mg apolipoprotein A-I (apoA-I)/dL; P = 0.001]. In normal-weight participants, the almond diet, relative to the control diet, increased α-1 HDL (33.7 ± 3.2 compared with 28.4 ± 2.6 mg apoA-I/dL), the α-1 to pre-β-1 ratio [geometric mean (95% CI): 4.3 (3.3, 5.7) compared with 3.1 (2.4, 4.0)], and non-ATP-binding cassette transporter A1 cholesterol efflux (8.3% ± 0.4% compared with 7.8% ± 0.3%) and decreased pre-β-2 (3.8 ± 0.4 compared with 4.6 ± 0.4 mg apoA-I/dL) and α-3 (23.5 ± 0.9 compared with 26.9 ± 1.1 mg apoA-I/dL) HDL ( P almonds for a carbohydrate-rich snack within a lower-saturated-fat diet may be a simple strategy to maintain a favorable circulating HDL subpopulation distribution and improve cholesterol efflux in normal-weight individuals with elevated LDL cholesterol.

    Two different concentrations (approx. 6 and 12%) and two presentations (raw and cooked) of dehydrated nopal were fed to laboratory rats and growth and serum total cholesterol, lipoprotein profile and glucose determined. Samples of raw and cooked nopal were chemically characterized for moisture, protein, ash, crude fiber, ether extract, total dietary fiber, reducing sugars, amino acids, minerals and gross energy. Cooking slightly affected some of the nutrients analyzed. After one month feeding, blood was withdrawn via intracardiac puncture and serum glucose, total cholesterol, HDL, LDL, and VLDL were determined. Rats fed 12% nopal had lower weight gains (P nopal or the control diet. Consumption of nopal did not affect (P > 0.05) glucose, total cholesterol and HDL cholesterol levels. However, rats fed raw nopal at the 12% concentration level had a 34% reduction in LDL cholesterol levels; thus, it was concluded that raw nopal had a potentially beneficial effect for hypercholesterolemic individuals.

    Defatted soybean flour (DSF) can sorb and concentrate blueberry anthocyanins and other polyphenols, but not sugars. In this study blueberry polyphenol-enriched DSF (BB-DSF) or DSF were incorporated into very high fat diet (VHFD) formulations and provided ad libitum to obese and hyperglycemic C57BL/6 mice for 13 weeks to investigate anti-diabetic effects. Compared to the VHFD containing DSF, the diet supplemented with BB-DSF reduced weight gain by 5.6%, improved glucose tolerance, and lowered fasting blood glucose levels in mice within 7 weeks of intervention. Serum cholesterol of mice consuming the BB-DSF-supplemented diet was 13.2% lower than mice on the diet containing DSF. Compounds were eluted from DSF and BB-DSF for in vitro assays of glucose production and uptake. Compared to untreated control, doses of BB-DSF eluate containing 0.05 – 10 μg/μL of blueberry anthocyanins significantly reduced glucose production by 24% - 74% in H4IIE rat hepatocytes, but did not increase glucose uptake in L6 myotubes. The results indicate that delivery of blueberry polyphenols stabilized in a high-protein food matrix may be useful for the dietary management of pre-diabetes and/or diabetes. PMID:23220243

    Full Text Available This experiment was conducted to determine the effects of enrichment housing design on performance, selected welfare indicators, chicken meat composition and serum cholesterol concentration of broiler chicken. For this purpose, 480 Ross-308 chicks were assigned to two groups, Control and Test, each with 4 replications. The pens of the Test Group were enriched with perches and sand bedding. At the end of the study, 8 males and 8 females whose live weights were close to the group average from each group were slaughtered. Their blood was collected and serum was separated. For chemical analysis of the chicken meat, whole carcasses of 4 males and 4 females, and half of the breast and left thigh from the remaining 4 males and 4 females were collected. In the carcass group, whole carcass with its bones was minced, whereas in the other groups breast and tight meat were separated from the bones and minced in a meat grinder, homogenized with an electronic mixer, then flash frozen (-40 °C, 8–10 h and stored (-20 °C, 3–4 weeks until analysed. There was no significant difference between the groups in body weight, daily weight gain, feed intake, feed conversion and survivability. Litter moisture of the sand bedding was lower than that of the wood shavings. Contact dermatitis of hocks was reduced in the Test Group (P P P P < 0.05. In conclusion, it was found that housing enriched with perches and sand bedding in addition to wood shavings bedding improved broiler welfare and meat quality.

    To determine if total serum cholesterol concentrations were altered in dogs with osteosarcoma. To evaluate association of total serum cholesterol concentration with clinical outcomes in dogs with appendicular osteosarcoma. Retrospective, multi-institutional study on 64 dogs with osteosarcoma. Control population consisted of dogs with traumatic bone fractures (n=30) and healthy patients of similar age and weight as those of the osteosarcoma cases (n=31). Survival analysis was done on 35 appendicular osteosarcoma patients that received the current standard of care. Statistical associations were assessed by univariable and multi-variable analysis. Information about age, sex, primary tumour location, total cholesterol concentration, monocytes and lymphocyte counts and alkaline phosphatase were also included. Total cholesterol was elevated above the reference interval (3·89 to 7·12 mmol/L) (150 to 275 mg/dL) in 29 of 64 (45·3%) osteosarcoma-bearing dogs, whereas similar elevations were found in only 3 of 30 (10%) fracture controls (Posteosarcoma. These results suggest that elevated total cholesterol is associated with canine osteosarcoma and may have prognostic significance. © 2017 British Small Animal Veterinary Association.

To examine the association between diet and circulating levels of blood lipid levels in a northern Swedish population. Study design . We compared a group with traditional lifestyle (TLS based on reindeer herding (TLS group with those from the same area with a non-traditional lifestyle (NTLS typical of more industrialized regions of Sweden (NTLS group. The analysis was based on self-reported intake of animal source food (i.e. non-game meat, game meat, fish, dairy products and eggs and the serum blood level of a number of lipids [total cholesterol (TC, low-density lipoprotein cholesterol (LDL, high-density lipoprotein cholesterol (HDL, triglycerides (TG, glycerophospholipids and sphingolipids]. Results . The TLS group had higher cholesterol, LDL and HDL levels than the reference group. Of the TLS group, 65% had cholesterol levels above the threshold for increased risk of coronary heart disease (≥240 mg/dl, as compared to 38% of the NTLS group. Self-reported consumption of game meat was positively associated with TC and LDL. Conclusions . The high game meat consumption of the TLS group is associated with increased cholesterol levels. High intake of animal protein and fat and low fibre is known to increase the risk of cardiovascular disease, but other studies of the TLS in northern Sweden have shown comparable incidences of cardiovascular disease to the reference (NTLS group from the same geographical area. This indicates that factors other than TC influence disease risk. One such possible factor is dietary phospholipids, which are also found in high amounts specifically in game meat and have been shown to inhibit cholesterol absorption.

    Precise evaluation of intracellular cholesterol distribution is crucial for improving diagnostics of diseased states associated with cholesterol alteration. Time-resolved fluorescence techniques are tested for non-invasive investigation of cholesterol in living cells. Fluorescent probe NBD attached to cholesterol was employed to evaluate cholesterol distribution in peripheral blood mononuclear cells (PBMC) isolated from the human blood. Fluorescence Lifetime Imaging Microscopy (FLIM) was successfully applied to simultaneously monitor the spatial distribution and the timeresolved characteristics of the NBD-cholesterol fluorescence in PBMC. Gathered data are the first step in the development of a new perspective non-invasive diagnostic method for evaluation of cholesterol modifications in diseases associated with disorders of lipid metabolism.

    Linseed oil has cardio-protective effects. However, its antihypertensive action has not yet been well characterized. The primary purpose of the study was to evaluate the effect of short-term dietary supplementation with linseed oil on blood pressure (BP) and lipid metabolism in patients with mild hypercholesterolemia. The secondary aim was to evaluate the effect of linseed oil on nitric oxide pathway and selected serum trace metals. 150 volunteers: 43 men (49.9±11.5 years) and 107 women (53.2±10.3 years), diagnosed with mild hypercholesterolemia, were assessed prospectively for BP and lipids' levels, before and after lipid-lowering diet plus linseed oil supplementation at a dose of 15 ml daily for 4 weeks (study groups) or 4-weekly lipid-lowering diet (control group). The multivariate logistic regression analysis model was used to determine the effect of linseed oil on BP after adjustment for age, gender, height, body weight, BMI, smoking and alcohol consumption. The supplementation with linseed oil significantly decreased LDL- and non-HDL cholesterol, and increased HDL- and HDL₃- cholesterol levels. Additionally, linseed oil decreased diastolic BP in men (CI:-6.0;-1.1, poil reduced (poil consumption was associated with a decrease in mean BP (aOR 3.85, 95%CI 1.32-11.33). Our findings confirm the benefit of short-term linseed oil use in mild hypercholesterolemia, in particular in patients with increased blood pressure.

    Berries are a particularly rich source of polyphenols. They also contain other bioactive substances, such as vitamin C. Previous studies indicated that the consumption of polyphenol-rich foods (eg, cocoa, tea, and red wine) may induce beneficial changes in pathways related to cardiovascular health. Whether the consumption of berries has similar effects is unknown. We aimed to investigate the effects of berry consumption on hemostatic function, serum lipids, and blood pressure (BP). Middle-aged unmedicated subjects (n = 72) with cardiovascular risk factors consumed moderate amounts of berry or control products for 8 wk in a single-blind, randomized, placebo-controlled intervention trial. Berry consumption inhibited platelet function as measured with a platelet function analyzer (using collagen and ADP as platelet activator) [changes: 11% and -1.4% in the berry and control groups, respectively; P = 0.018, analysis of covariance (ANCOVA)]. Plasma biomarkers of platelet activation, coagulation, and fibrinolysis did not change during the intervention. Serum HDL-cholesterol concentrations increased significantly more (P = 0.006, ANCOVA) in the berry than in the control group (5.2% and 0.6%, respectively), but total cholesterol and triacylglycerol remained unchanged. Systolic BP decreased significantly (P = 0.050, ANCOVA); the decrease mostly occurred in subjects with high baseline BP (7.3 mm Hg in highest tertile; P = 0.024, ANCOVA). Polyphenol and vitamin C concentrations in plasma increased, whereas other nutritional biomarkers (ie, folate, tocopherols, sodium, and potassium) were unaffected. The consumption of moderate amounts of berries resulted in favorable changes in platelet function, HDL cholesterol, and BP. The results indicate that regular consumption of berries may play a role in the prevention of cardiovascular disease.

    Inflammation is triggered after invasion or injury to restore homeostasis. Although the activation of Wnt/β-catenin signaling is one of the first molecular responses to cellular damage, its role in inflammation is still unclear. It was our hypothesis that the low-density lipoprotein (LDL) receptor-related protein 5 (LRP5) and the canonical Wnt signaling pathway are modulators of inflammatory mechanisms. Wild-type (WT) and LRP5(-/-) mice were fed a hypercholesterolemic (HC) diet to trigger dislipidemia and chronic inflammation. Diets were supplemented with plant sterol esters (PSEs) to induce LDL cholesterol lowering and the reduction of inflammation. HC WT mice showed increased serum cholesterol levels that correlated with increased Lrp5 and Wnt/β-catenin gene expression while in the HC LRP5(-/-) mice Wnt/β-catenin pathway was shut down. Functionally, HC induced pro-inflammatory gene expression in LRP5(-/-) mice, suggesting an inhibitory role of the Wnt pathway in inflammation. Dietary PSE administration downregulated serum cholesterol levels in WT and LRP5(-/-) mice. Furthermore, in WT mice PSE increased anti-inflammatory genes expression and inhibited Wnt/β-catenin activation. Hepatic gene expression of Vldlr, Lrp2 and Lrp6 was increased after HC feeding in WT mice but not in LRP5(-/-) mice, suggesting a role for these receptors in the clearance of plasmatic lipoproteins. Finally, an antiatherogenic role for LRP5 was demonstrated as HC LRP5(-/-) mice developed larger aortic atherosclerotic lesions than WT mice. Our results show an anti-inflammatory, pro-survival role for LRP5 and the Wnt signaling pathway in peripheral blood leukocytes.

    Lactic acid bacteria (LAB) are beneficial probiotic organisms that contribute to improved nutrition, microbial balance, and immuno-enhancement of the intestinal tract, as well as lower cholesterol. Although present in many foods, most trials have been in spreads or dairy products. Here we tested whether Bifidobacteria isolates could lower cholesterol, inhibit harmful enzyme activities, and control fecal water content. In vitro culture experiments were performed to evaluate the ability of Bifidobacterium spp. isolated from healthy Koreans (20 approximately 30 years old) to reduce cholesterol-levels in MRS broth containing polyoxyethanylcholesterol sebacate. Animal experiments were performed to investigate the effects on lowering cholesterol, inhibiting harmful enzyme activities, and controlling fecal water content. For animal studies, 0.2 ml of the selected strain cultures (108 approximately 109 CFU/ml) were orally administered to SD rats (fed a high-cholesterol diet) every day for 2 weeks. B. longum SPM1207 reduced serum total cholesterol and LDL levels significantly (p water content, and reduced body weight and harmful intestinal enzyme activities. Daily consumption of B. longum SPM1207 can help in managing mild to moderate hypercholesterolemia, with potential to improve human health by helping to prevent colon cancer and constipation.

    Obesity leads to increased ischemic heart disease (IHD) risk, but the risk is thought to be mediated through intermediate variables and may not be caused by increased weight per se. To test the hypothesis that the increased IHD risk because of obesity is mediated through lipoproteins, blood pressure, glucose, and C-reactive protein. Approximately 90 000 participants from Copenhagen were included in a Mendelian randomization design with mediation analyses. Associations were examined using conventional measurements of body mass index and intermediate variables and using genetic variants associated with these. During ≤22 years of follow-up 13 945 participants developed IHD. The increased IHD risk caused by obesity was partly mediated through elevated levels of nonfasting remnant cholesterol and low-density lipoprotein cholesterol, through elevated blood pressure, and possibly also through elevated nonfasting glucose levels; however, reduced high-density lipoprotein cholesterol and elevated C-reactive protein levels were not mediators in genetic analyses. The 3 intermediate variables that explained the highest excess risk of IHD from genetically determined obesity were low-density lipoprotein cholesterol with 8%, systolic blood pressure with 7%, and remnant cholesterol with 7% excess risk of IHD. Corresponding observational excess risks using conventional body mass index were 21%, 11%, and 20%, respectively. The increased IHD risk because of obesity was partly mediated through elevated levels of nonfasting remnant and low-density lipoprotein cholesterol and through elevated blood pressure. Our results suggest that there may be benefit to gain by reducing levels of these risk factors in obese individuals not able to achieve sustained weight loss. © 2014 American Heart Association, Inc.

    Cervical radiation therapy is often applied to patients with head and neck cancers because radiation has a high sensitivity to these cancers and permits the preservation of functions and physical form. However, it has been shown that various complications can result from radiation therapy. We have encountered some patients who showed hypercholesterolemia resulting from cervical radiation. Therefore, we have paid close attention to the relationship between hypercholesterolemia after cervical radiation and hypothyroidism. Thyroid hormone tests in these patients with hypercholesterolemia after cervical radiation showed high thyroid stimulating hormone (TSH) and low free thyroxine (fT 4 ), indicating the presence of hypothyroidism. After administration of levothyroxine Na, their fT 4 levels increased and both TSH levels and serum total cholesterol levels decreased. In conclusion, in patients who have received cervical radiation, we recommend monitoring serum total cholesterol periodically to detect hypothyroidism easily before the appearance of its symptoms.

    Chilean aboriginal populations (Mapuche) predominantly live in the region of Araucanía, in the southern part of the country. Their cardiovascular risk factors have not been systematically assessed. To study the prevalence of cardiovascular risk factors in the Mapuche population. Blood pressure, weight, height, dietary habits, fasting serum total cholesterol, HDL cholesterol and triglycerides were measured in 1.948 adults living in 28 Mapuche communities. Thirteen percent of males and 16% of females had high blood pressure. Body mass index was 25.5 kg/m2 in males and 28.1 kg/m2 in females. Forty five percent of women and 24% of men were classified as obese. Mean serum total cholesterol was 186.7 +/- 9.6 mg/dl, HDL cholesterol was 58.7 +/- 30.7 mg/dl, total cholesterol/HDL cholesterol was 3.4 +/- 2 and triglycerides were 155.2 +/- 91.2 mg/dl. Twenty eight percent of males and 9.6% of females smoked. Mapuche individuals have higher levels of HDL cholesterol a better total cholesterol/HDL cholesterol ratio and lower frequency of smoking than non aboriginal Chileans subjects.

    We examined how serum cholesterol, an established risk factor for cerebrovascular disease (CVD), relates to cognitive function in healthy middle-older aged individuals with no neurologic or CVD history. A complete lipid panel was obtained from a cohort of one hundred twenty individuals, ages 43-85, who also underwent a comprehensive neuropsychological examination. In order to reduce the number of variables and empirically identify broad cognitive domains, scores from neuropsychological tests were submitted into a factor analysis. This analysis revealed three explainable factors: Memory, Executive Function and Memory/Language. Three separate hierarchical multiple regression analyses were conducted using individual cholesterol metrics (total cholesterol, low density lipoprotein; LDL, high density lipoprotein; HDL, and triglycerides), as well as age, education, medication status (lipid lowering agents), ApoE status, and additional risk factors for CVD to predict neuropsychological function. The Memory Factor was predicted by a combination of age, LDL, and triglyceride levels; both age and triglycerides were negatively associated with factor score, while LDL levels revealed a positive relationship. Both the Executive and Memory/Language factor were only explained by education, whereby more years were associated with better performance. These results provide evidence that individual cholesterol lipoproteins and triglycerides may differentially impact cognitive function, over and above other common CVD risk factors and ApoE status. Our findings demonstrate the importance of consideration of vascular risk factors, such as cholesterol, in studies of cognitive aging.

    Two experiments were conducted in the rat to determine the relationships of serum cholesterol (SC, mg/dl), apparent digestibility of dry matter (DDM, %), and digested energy intake (DE, kcal/day) at suboptimal level of energy. The energies in diet and feces were determined by calorimetry. DE as percentage of the National Research Council requirement (DE%) was suboptimal (70 to 85%). The experiments had four to five isofibrous diets, and no fiber diets, supplemented with 0.2% crystalline cholesterol (CChol). Animals in experiment 1 were fed varying amounts of feed with 18% coconut oil in the diets where as these in experiment 2 were given fixed amounts of feed with either 6 or 18% oil. The following regressions (p less than 0.001) for SC were found: experiment 1: -1157.7 -5.97 DDM +105.5 CCI -1.48 CCI2 (r2 0.35), where CCI = CChol, mg/day; -1888.4 -2.66 DE +120.97 CCI -1.62 CCI2 (r2 0.37). Experiment 2: 762.99 -6.15 DDM -0.8 fat cal % -0.87DE% (r2 0.31), where fat cal % = fat calories % of DE. Data indicate that at suboptimal energy intake, SC was inversely related to (1) DDM, (2) fat cal, and (3) total energy intake. Liver cholesterol lowering effect of the dietary fiber was also observed. The above findings help to elucidate various conflicting reports related to diet and blood cholesterol.

    Many peripheral biomarkers, including low cholesterol and its fractions, have been examined to identify suicidal behavior. Herein, we assessed serum lipid profile and some proteins putatively associated with suicidal behavior in subjects with mood disorder (bipolar disorder or major depressive disorder) with a recent suicide attempt and with no lifetime history of suicide attempts. Fifty subjects had presented an episode of attempted suicide during the last 15 days, and 36 subjects had no history of any suicide attempt. We measured total cholesterol, HDL, LDL and triglycerides as well as serum leptin, brain-derived neurotrophic factor (BDNF), S100B and C-reactive protein (CRP). Individuals that had attempted suicide presented decreased body mass index (BMI) and waist circumference. After adjusting for these confounders, we found that triglycerides were decreased in attempted suicide subjects. We found no differences among total cholesterol, LDL, and HDL or leptin, S100B, CRP and BDNF. This is a cross-sectional study, and we cannot therefore assess whether a decrease in triglycerides caused a mood episode with suicidal ideation that led to a suicide attempt or if the presence of a mood episode originated a loss of appetite and consequent loss of weight, therefore decreasing triglyceride levels. These results do not support the hypothesis that lower levels of cholesterol are associated with suicidal behavior in a mood disorder sample. However, our data support the idea that adiposity is differentiated in these patients (reduced BMI, waist circumference and serum triglycerides), which could lead to an altered communication between the adipose tissue and brain.

    Consumption of a cholesterol lowering dietary portfolio including plant sterols (PS), viscous fibre, soy proteins and nuts for 6 months improves blood lipid profile. Plant sterols reduce blood cholesterol by inhibiting intestinal cholesterol absorption and concerns have been raised whether PS consumption reduces fat soluble vitamin absorption. The objective was to determine effects of consumption of a cholesterol lowering dietary portfolio on circulating concentrations of PS and fat soluble vitamins. Using a parallel design study, 351 hyperlipidemic participants from 4 centres across Canada were randomized to 1 of 3 groups. Participants followed dietary advice with control or portfolio diet. Participants on routine and intensive portfolio involved 2 and 7 clinic visits, respectively, over 6 months. No changes in plasma concentrations of α and γ tocopherol, lutein, lycopene and retinol, but decreased β-carotene concentrations were observed with intensive (week 12: p = 0.045; week 24: p = 0.039) and routine (week 12: p = 0.031; week 24: p = 0.078) portfolio groups compared to control. However, cholesterol adjusted β-carotene and fat soluble compound concentrations were not different compared to control. Plasma PS concentrations were increased with intensive (campesterol:p = 0.012; β-sitosterol:p = 0.035) and routine (campesterol: p = 0.034; β-sitosterol: p = 0.080) portfolio groups compared to control. Plasma cholesterol-adjusted campesterol and β-sitosterol concentrations were negatively correlated (p portfolio diet reduces serum total and LDL-C levels while increasing PS values, without altering fat soluble compounds concentrations. The extent of increments of PS with the current study are not deleterious and also maintaining optimum levels of fat soluble vitamins are of paramount necessity to maintain overall metabolism and health. Results indicate portfolio diet as one of the best options for CVD risk reduction

    Full Text Available Atherosclerosis is the excess of fat and stiffness of arteries sidewalls in which specific areas of the circulatory system are involved, causing specific signs based on the involved area, the characteristics of the lesion, and the severity of involvement. The only factor necessary to cause atherosclerosis is the high level of LDL cholesterol. Today, drugs such as lovastatin, clofibrate, and Klystramyn are applied to reduce LDL and increase HDL levels. Material and methods: The effect of fenugreek seeds without any drugs or with clofibrat on blood lipids profile and fatty streak forming were evaluated in 25 male healthy rabbits. The rabbits were divided into 5 group of 5 and received the following diets and drugs for 45 days: Group Ι, normal diet without any drugs Group Π, high cholesterol diet without any drugs Group ΙΙΙ, high cholesterol diet in addition to germinated fenugreek seeds powder (600 mg bid Group ΙV, high cholesterol diet in addition to clofibrat (50 mg bid and GroupV, high cholesterol diet in addition to clofibrat (50 mg bid and germinated fenugreek seeds powder (600 mg bid. The blood samples were collected after overnight fasting at the beginning and at the end of the test period and were estimated for lipids profile. Also autopsy and aortic cross-sectional sampling was conducted for microscopic study after the experiment. Result: The serum total cholesterol, LDL, and triglyceride levels of groups ΙΙΙ, ΙV,V increased less than those in group Π but HDL levels in groups ΙΙΙ, ΙV and V increased more than that in group Π (P<0.001. Furthermore, the intensity of fatty streak was less in group V. Conclusion: This result indicates the usefulness of fenugreek seeds in the management of hyperlipidemia and atherosclerosis (P<0.05

    A method based on Asymmetric Flow Field-Flow Fractionation (AF4) was developed to separate different types of lipoproteins from human serum. The emphasis in the method optimization was on the possibilities to characterize the largest lipoprotein fractions (LDL and VLDL), which is usually not possible with the size-exclusion chromatography methods applied in routine analysis. Different channel geometries and flow programs were tested and compared. The use of a short fractionation channel was shown to give less sample dilution at the same fractionation power compared to a conventional, long channel. Different size selectivities were obtained with an exponential decay and a linear cross flow program. The ratio of the UV absorption signal to the light scattering signal was used to validate the relation between retention time and size of the fractionated particles. An experimental setup was developed for the simultaneous determination of the cholesterol and triglycerides distribution over the lipoprotein fractions, based on enzymatic reactions followed by UV detection at 500 nm. Coiled and knitted PTFE tubing reactors were compared. An improved peak sharpness and sensitivity were observed with the knitted tubing reactor. After optimization of the experimental conditions a satisfactory linearity and precision (2-3% rsd for cholesterol and 5-6% rsd for triglycerides) were obtained. Finally, serum samples, a pooled sample from healthy volunteers and samples of sepsis patients, were analyzed with the method developed. Lipoprotein fractionation and cholesterol and triglyceride distributions could be correlated with the clinical background of the samples.

    In view to high incidence of thyroid dis function among Sudanese females, this study was conducted, essentially to study the effect of thyroid disorders on lipids metabolism, mainly on total cholesterol. In this study samples were collected from RIA laboratory in Sudan Atomic Energy Commission. 50 hyperthyroidism females were selected as a study group of age range (20-55) years. In addition 47 samples were collected with same age of study group used as control group. Thyroid related hormones thyroxine T4, triiodothyronine T3, thyroid stimulating hormone TSH using the sensitive radioimmunoassay method and cholesterol were measured for the two groups using enzymatic-calorimetric test. Statistical analysis were done with SPSS computer program to compare the cholesterol levels in the control subjects with the patients levels. The results showed significantly decreased cholesterol level of patient group when compared with the control group (p<0.01). At the end of this study the result was agreed well with previous results concerning cholesterol level as affected by thyroid disorder. (Author)

    Restricted sodium intake has been recommended for more than 1 century for the treatment of hypertension. However, restriction seems to increase blood cholesterol. In women with excess weight, blood cholesterol may increase even more because of insulin resistance and the high lipolytic activity of adipose tissue.The aim of this study was to assess the association between blood cholesterol and sodium intake in hypertensive women with and without excess weight.This was a cross-sectional study with hypertensive and nondiabetic women aged 20 to 59 years, recruited at the primary healthcare units of Maceio, Alagoas, Brazilian Northeast. Excess weight was defined as body mass index (BMI) ≥25.0 kg/m. Sodium intake was estimated by the 24-hour urinary excretion of sodium. Blood cholesterol was the primary outcome investigated by this study, and its relationship with sodium intake and other variables was assessed by Pearson correlation and multivariate linear regression using a significance level of 5%.This study included 165 hypertensive women. Of these, 135 (81.8%) were with excess weight. The mean sodium intake was 3.7 g (±1.9) and 3.4 g (±2.4) in hypertensive women with and without excess weight, respectively. The multiple normal linear regression models fitted to the "blood cholesterol" in the 2 groups reveal that for the group of hypertensive women without excess weight only 1 independent variable "age" is statistically significant to explain the variability of the blood cholesterol levels. However, for the group of hypertensive women with excess weight, 2 independent variables, age and sodium intake, can statistically explain variations of the blood cholesterol levels.Blood cholesterol is statistically inversely related to sodium intake for hypertensive women with excess weight, but it is not statistically related to sodium intake for hypertensive women without excess weight.

    It is known that deformation of red blood cells (RBCs) is linked to ATP release from the cells. Further, membrane cholesterol has been shown to alter properties of the cell membrane such as fluidity and bending stiffness. Membrane cholesterol content is increased in some cardiovascular diseases, for example, in individuals with acute coronary syndromes and chronic stable angina, and therefore, because of the potential clinical relevance, we investigated the influence of altered RBC membrane cholesterol levels on ATP release. Because of the correlation between statins and reduced membrane cholesterol in vivo, we also investigated the effects of simvastatin on RBC deformation and ATP release. We found that reducing membrane cholesterol increases cell deformability and ATP release. We also found that simvastatin increases deformability by acting directly on the membrane in the absence of the liver, and that ATP release was increased for cells with enriched cholesterol after treatment with simvastatin.

    Important public health problems worldwide such as obesity, diabetes, hyperlipidemia and coronary diseases are quite common. These problems arise from numerous factors, such as hyper-caloric diets, sedentary habits and other epigenetic factors. With respect to Mexico, the population reference values of total cholesterol in plasma are around 200 mg/dL. However, a large proportion has higher levels than this reference value. In this work, we analyze the rheological properties of human blood obtained from 20 donors, as a function of cholesterol and triglyceride levels, upon a protocol previously approved by the health authorities. Samples with high and low cholesterol and triglyceride levels were selected and analyzed by simple-continuous and linear-oscillatory shear flow. Rheometric properties were measured and related to the structure and composition of human blood. In addition, rheometric data were modeled by using several constitutive equations: Bautista-Manero-Puig (BMP) and the multimodal Maxwell equations to predict the flow behavior of human blood. Finally, a comparison was made among various models, namely, the BMP, Carreau and Quemada equations for simple shear rate flow. An important relationship was found between cholesterol, triglycerides and the structure of human blood. Results show that blood with high cholesterol levels (400 mg/dL) has flow properties fully different (higher viscosity and a more pseudo-plastic behavior) than blood with lower levels of cholesterol (tendency to Newtonian behavior or viscosity plateau at low shear rates).

    This study aimed to explore the activity of pericarp extract of mangosteen (Garcinia mangostana L.). Mangosteen pericarp contains various active compounds which are beneficial for human health. In-vivo antioxidant assay of pericarp extract was carried out using 3-4 month male mice of strain BALB/c weighed 30-40 g. The mice were divided into two groups: normal control (KN) group and STZ-induced diabetic group. STZ induction was performed using multiple low-dose method 30 mg/kg body weight treated daily for five consecutive days. Diabetic group was separated into two subgroups: diabetic control (KD), metformin control (KM), and crude extract treatment subgroups. The fasting blood glucose and the cholesterol level were measured before and after lard treatment, we also did it on the first, seventh, and fourteenth day of mangosteen pericarp crude extract treatment. The mice were treated with mangosteen pericarp crude extract for 14 days. The MDA level of the fasting blood serum was measured. The body weight and fasting blood cholesterol level before and after lard treatment were analyzed by t-test, whereas, the fasting blood cholesterol and the MDA level were analyzed using one-way variant analysis continued with Duncan test. The correlation between the increasing body weight and the fasting blood cholesterol level was determined by Pearson correlation test. The results of the study showed that the administration of mangosteen pericarp crude extract was able to reduce the fasting blood cholesterol and the malondialdehide level significantly.

    Full Text Available To investigate the effect of low dose amlodipine v/s nifedipine on serum cholesterol profile of rabbits receiving standard diet. Methods: Fourty Newzealand rabbits were selected for the study. Their cholesterol profile was estimated at the beginning of the study. Rabbits were grouped into 4 groups receiving standard diet (control group, standard diet + vehicle propylene glycol, standard diet + nifedipine dissolved in propylene glycol and standard diet + amlodipine dissolved in propylene glycol. Along with standard diet they were treated with respective drugs for ten weeks. At the end of ten weeks serum cholesterol profile was estimated. Results: The cholesterol profile was estimated at the beginning and at the end of ten weeks. Total cholesterol in the amlodipine group decreased from 97±4.06 mg/dl to 90±4.2 mg/dl and HDL-Cholesterol increased from 32.01±4.40 mg/dl to 37±4.60 mg/dl after 10 week treatment but these changes were not significant. LDL cholesterol decreased significantly in rabbits with low dose of amlodipine from 55.42±3.32 mg/dl to 32.40±3.22 mg/dl and. In the nifedipine group there was a slight increase in total cholesterol from 102.49±5.16 mg/dl to 106±5.39 mg/dl, HDL cholesterol from 34.10±2.80 to 35.16±2.82 mg/dl and LDL cholesterol also increased from 56.20±2.20 mg/dl to 59.00±2.20 mg/dl after 10 week treatment. Conclusion: The study shows amlodipine produces favorable alterations in serum cholesterol profile

    Underlying mechanisms responsible for the cholesterol-lowering effect of β-glucan have been proposed, yet have not been fully demonstrated. The primary aim of this study was to determine whether the consumption of barley β-glucan lowers cholesterol by affecting the cholesterol absorption, cholesterol synthesis or bile acid synthesis. In addition, this study was aimed to assess whether the underlying mechanisms are related to cholesterol 7α hydroxylase (CYP7A1) SNP rs3808607 as proposed by us earlier. In a controlled, randomised, cross-over study, participants with mild hypercholesterolaemia (n 30) were randomly assigned to receive breakfast containing 3 g high-molecular weight (HMW), 5 g low-molecular weight (LMW), 3 g LMW barley β-glucan or a control diet, each for 5 weeks. Cholesterol absorption was determined by assessing the enrichment of circulating 13C-cholesterol over 96 h following oral administration; fractional rate of synthesis for cholesterol was assessed by measuring the incorporation rate of 2H derived from deuterium oxide within the body water pool into the erythrocyte cholesterol pool over 24 h; bile acid synthesis was determined by measuring serum 7α-hydroxy-4-cholesten-3-one concentrations. Consumption of 3 g HMW β-glucan decreased total cholesterol (TC) levels (P=0·029), but did not affect cholesterol absorption (P=0·25) or cholesterol synthesis (P=0·14). Increased bile acid synthesis after consumption of 3 g HMW β-glucan was observed in all participants (P=0·049), and more pronounced in individuals carrying homozygous G of rs3808607 (P=0·033). In addition, a linear relationship between log (viscosity) of β-glucan and serum 7α-HC concentration was observed in homozygous G allele carriers. Results indicate that increased bile acid synthesis rather than inhibition of cholesterol absorption or synthesis may be responsible for the cholesterol-lowering effect of barley β-glucan. The pronounced TC reduction in G allele carriers of rs

    Full Text Available The present work reports the effect of aubergine extract on serum and hepatic cholesterol and triglycerides levels in adult rats. Fisher rats were divided into three groups: the first one received a normolipidic diet and water , serving as a control; the other two received a hypercholesterolaemic diet with 30% vegetable oil and 1% cholesterol, one of these being given water while the other was given an aubergine extract. After 28 days the animals were sacrificed and serum and hepatic cholesterol and triglycerides levels were assessed. The obtained results indicated that under the experimental conditions employed, the aubergine extract increased serum and decreased hepatic cholesterol and had little or no effect on both serum and hepatic triglycerides.A beringela (Solanum melongena tem sido apontada como possuidora da capacidade de reduzir o colesterol sérico. O chá do vegetal vem sendo utilizado com este propósito, devido ao interesse na descoberta de formas alternativas para o controle da hipercolesterolemia. No presente trabalho testou-se o efeito do chá de beringela nos níveis séricos e hepáticos de colesterol e triglicerídeos em ratos adultos. Ratos Fisher foram divididos em três grupos: o primeiro recebeu dieta normolipídica ad libitum e água para beber, funcionando como controle; os outros dois receberam dieta hipercolesterolêmica com 30% de óleo vegetal e 1% de colesterol, sendo dada a um destes grupos água para beber, enquanto que o outro recebeu apenas chá de beringela. Após 28 dias os animais foram sacrificados e dosaram-se os níveis de colesterol e triglicerídeos séricos e hepáticos. Os resultados obtidos indicam que, nas condições experimentais utilizadas, o chá de beringela eleva o colesterol sérico, reduz o hepático e tem pouco ou nenhum efeito sobre os triglicerídeos, tanto séricos quanto hepáticos.

    This double-blind, randomized, placebo-controlled, cross-over intervention-study was conducted in healthy volunteers to evaluate the effects of plant sterol ester supplemented margarine on cholesterol, non-cholesterol sterols and oxidative stress in serum and monocytes. Sixteen volunteers, average age 34 years, with no or mild hypercholesterolemia were subjected to a 4 week period of daily intake of 3g plant sterols per day supplied via a supplemented margarine on top of regular eating habits. After a wash-out period of one week, volunteers switched groups. Compared to placebo, a diet supplementation with plant sterols increased serum levels of plant sterols such as campesterol (+0.16±0.19mg/dL, p=0.005) and sitosterol (+0.27±0.18mg/dL, psynthesis such as desmosterol (+0.05±0.07mg/dL, p=0.006) as well as lathosterol (+0.11±0.16mg/dL, p=0.012). Cholesterol serum levels, however, were not changed significantly (+18.68±32.6mg/dL, p=0.052). These findings could not be verified in isolated circulating monocytes. Moreover, there was no effect on monocyte activation and no differences with regard to redox state after plant sterol supplemented diet. Therefore, in a population of healthy volunteers with no or mild hypercholesterolemia, consumption of plant sterol ester supplemented margarine results in increased concentrations of plant sterols and cholesterol synthesis markers without affecting total cholesterol in the serum, activation of circulating monocytes or redox state.

    Full Text Available This study’s aim was to test the low-density lipoprotein cholesterol- (LDL-c- lowering efficacy of biscuits containing 2 g of plant stanols, which corresponded to 3.4 g of plant stanol esters. The biscuit is a new food format that can be consumed as a snack. In a double-blind, placebo-controlled parallel design study, 119 mildly to moderately hypercholesterolemic volunteers were randomized to plant stanol or control groups. Subjects were comparable in age, gender, lipid profiles, and body mass index. They consumed a control biscuit once a day for a two-week period, followed by a four-week intervention period that either had a plant stanol ester biscuit or a control. During the habitual diet, one biscuit per day was consumed at any time that subjects wished. Serum lipid profiles were measured at the first day of run-in, at baseline, and at the study’s end. Compared to the control, the total cholesterol (TC, LDL-c, and the LDL-to-high-density lipoprotein (LDL/HDL ratio had serum reductions of 4.9%, 6.1%, and 4.3%, respectively, and were observed after 4 weeks of biscuit consumption with added plant stanols (P < 0.05. A significantly higher reduction in LDL-c (8.9% and LDL/HDL ratio (11.4% was measured in those taking a plant stanol biscuit with a meal compared to those who consumed a plant stanol biscuit without other food. In conclusion, incorporating plant stanols into a biscuit is an attractive, convenient, and acceptable way to modestly lower elevated cholesterol concentrations. For optimal efficacy, biscuits should be consumed with a meal as part of a healthy diet.

    Working outside daylight hours (7 am to 7 pm) is called shift work. Shift work is a common practice in many industries and factories such as steel industries, petroleum industries, power plants, and in some services such as medicine and nursing and police forces, in which professionals provide services during day and night. Considering the contradictory reports of different studies, we decided to evaluate the effect of shift work on cholesterol and triglyceride (TG) levels through a historical cohort on steel industry workers. This retrospective cohort study was performed on all the staff of Isfahan's Mobarakeh Steel Company between years 2002 and 2011. There were 5773 participants in this study. Data were collected from the medical records of the staff using the census method. For analysis of data, generalized estimating equation (GEE) regression was used. The results showed a significant difference in cholesterol levels between shift workers and day workers on the first observation (P work experience and BMI were not similar between shift workers and day workers. Therefore, to remove the effect of such variables, we used GEE regression. Despite the borderline difference of cholesterol between regular shift workers and day workers, this correlation was not statistically significant (P = 0.051). The results for TG also showed no correlation with shift work. According to the findings of this study, there is no relationship between shift work and changes in serum TG and cholesterol. The lack of relationship can be due to shift plans for shift workers, nutrition, or the "Healthy Heart project" at Isfahan Mobarakeh Steel Company.

    Aim: The present study was conducted to evaluate the serum triglycerides, serum cholesterol, total protein, and IgG levels in elderly patients who were affected by periodontal disease. Materials and Methods: This study was conducted at the Rajah Muthiah Dental College and Hospital in the periodontics division. The study was conducted for a period of 3 months. This study is a prospective analytical study. Sixty individuals who were systemically healthy in the age group of 50 and above were included in this study. Control and experimental groups of 30 participants each were included. Plaque index, gingival index, probing pocket depth, and clinical attachment loss were recorded. Biochemical parameters such as serum cholesterol, serum triglycerides, total protein, and IgG levels were also evaluated and correlated with the periodontal parameters. Data was analyzed using SPSS version 16.0 (IBM Corp., Armonk, NY). The relationship between periodontal status and the biochemical parameters such as serum cholesterol, serum triglycerides, total protein, and IgG levels were evaluated by Student's t-test. Results: There was no significant difference in the plaque and gingival scores between the experimental and control group. It was observed that serum cholesterol level and total protein level was lower in participants suffering from chronic periodontitis. Triglycerides level was significantly elevated in the experimental group. IgG, a level which is not significant, concluded that there is no difference in control and experimental group. Conclusion: It was concluded from the results obtained from the study that there is an association between serum triglycerides, serum cholesterol, total protein, and periodontal disease. However, further longitudinal and well-controlled studies are required to evaluate the relationship between these biochemical parameters and periodontal disease. PMID:28462181

This study was conducted at the Rajah Muthiah Dental College and Hospital in the periodontics division. The study was conducted for a period of 3 months. This study is a prospective analytical study. Sixty individuals who were systemically healthy in the age group of 50 and above were included in this study. Control and experimental groups of 30 participants each were included. Plaque index, gingival index, probing pocket depth, and clinical attachment loss were recorded. Biochemical parameters such as serum cholesterol, serum triglycerides, total protein, and IgG levels were also evaluated and correlated with the periodontal parameters. Data was analyzed using SPSS version 16.0 (IBM Corp., Armonk, NY). The relationship between periodontal status and the biochemical parameters such as serum cholesterol, serum triglycerides, total protein, and IgG levels were evaluated by Student's t-test. There was no significant difference in the plaque and gingival scores between the experimental and control group. It was observed that serum cholesterol level and total protein level was lower in participants suffering from chronic periodontitis. Triglycerides level was significantly elevated in the experimental group. IgG, a level which is not significant, concluded that there is no difference in control and experimental group. It was concluded from the results obtained from the study that there is an association between serum triglycerides, serum cholesterol, total protein, and periodontal disease. However, further longitudinal and well-controlled studies are required to evaluate the relationship between these biochemical parameters and periodontal disease.

    There are many indications that interaction of serum proteins with intravenously injected cationic lipoplexes disturbs lipofection in vitro and in vivo. However, transfection with certain lipid compositions such as N-[1- (2,3-dioleoyloxy)propyl]-N,N,N-trimethylammonium chloride (DOTAP)/cholesterol appears to be more resistant to serum and more efficacious. We investigated the mechanism of interaction between fluorescently labeled lipoplexes of the above composition and fluorescently labeled serum proteins. Fluorescence resonance energy transfer measurements in vitro indicate that serum proteins interact instantly and closely with the DOTAP/cholesterol lipoplexes. In accord with this, preinjection of fluorescently labeled serum into mice before injection of lipoplexes showed an immediate association of proteins with lipoplexes. Serum proteins colocalized with the lipoplexes in the lung vasculature; however, they dissociated from the cationic lipid as soon as 1 hr postinjection, probably because of displacement of serum proteins from lipoplexes by extracellular proteoglycans. Indeed, this displacement was imitated by heparin, a typical glycosaminoglycan, and could be explained by the inability of weakly acidic serum proteins to neutralize the DOTAP/cholesterol electrical surface potential psi0. The stability of the cationic lipid psi0 in serum could be a key reason for the high lung association and transfection efficiency with this formulation.

    Total reflection x-ray fluorescence was applied in the analysis of a pool human blood serum sample, which was collected out of 100 healthy individuals during an ordinary day at a hospital in Athens. Direct measurements of 4 1 quantities were performed in a standard TRXRF module, but with the addition of a Mo filter after the cut-off reflector. In this way the exciting beam was further monochromatized leading to an improved peak to background ratio. The elements S, Cl, K, Ca, Fe, Cu, Zn, Se, Br, Rb were detected, with detection limits in the low ppb region for the elements of interest. The determined trace elements concentrations were found to be in very good agreement with values already reported in literature. For intercomparison a quantity of the same sample was freeze dried and measured in a secondary target assembly, in the form of pellets, giving almost identical results. The trace elements concentrations obtained can be considered as representative values for healthy population of Athens and therefore can be used as a monitor in order to associate the lack or excess of certain trace elements with pathological cases.

    We tested whether serum total cholesterol levels might be associated with recent suicide attempts in subjects with major depressive disorder, after controlling for relevant individual characteristics. We conducted a comparative cross-sectional study including consecutive inpatients with major depressive disorder. We differentiated subjects admitted for a recent serious (violent or non-violent) suicide attempt and those without such recent history. Total cholesterol was measured from fasting blood tests. At univariate analyses, suicide attempters had levels of total cholesterol (174.0±45.7mg/dL) lower than non-attempters (193.9±42.6mg/dL) (p=0.004). This was confirmed among both violent (174.1±46.2mg/dL) and non-violent (173.8±46.1mg/dL) suicide attempters (p=0.035 and 0.016, respectively). However, logistic regression analyses, sequentially including demographic, clinical (comorbid alcohol and personality disorders), and biochemical factors, did not show any association between serum cholesterol and recent suicide attempts (p=0.172). Similar findings were observed in multinomial logistic regression analyses, for both violent (p=0.512) and non-violent (p=0.157) suicide attempts. Our findings do not support the hypothesis that serum cholesterol and suicide attempts are associated among subjects with major depressive disorder. The identification of valid and accessible biological markers of suicidal behaviors still represents a challenge for future research. Copyright © 2016 The Canadian Society of Clinical Chemists.

    The authors aimed to quantify the effects of current systolic blood pressure (SBP) and serum total cholesterol on the risk of mortality in comparison with SBP or serum cholesterol 25 years previously, taking measurement error into account. The authors reanalyzed 35-year follow-up data on mortality due to coronary heart disease and stroke among subjects aged 65 years or more from nine cohorts of the Seven Countries Study. The two-step method of Tsiatis et al. (J Am Stat Assoc 1995;90:27-37) was used to adjust for regression dilution bias, and results were compared with those obtained using more commonly applied methods of adjustment for regression dilution bias. It was found that the commonly used univariate adjustment for regression dilution bias overestimates the effects of both SBP and cholesterol compared with multivariate methods. Also, the two-step method makes better use of the information available, resulting in smaller confidence intervals. Results comparing recent and past exposure indicated that past SBP is more important than recent SBP in terms of its effect on coronary heart disease mortality, while both recent and past values seem to be important for effects of cholesterol on coronary heart disease mortality and effects of SBP on stroke mortality. Associations between serum cholesterol concentration and risk of stroke mortality are weak.

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

    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.

    Full Text Available The objectives of this study were to determine the effect of various fractions of mangosteen (Garcinia mangostana pericarp extract to the changes of the fasting blood cholesterol and serum malondialdehyde (MDA levels on diabetic mice (Mus musculus. Thirty 3-4 months old male mice strain BALB/c, weight 20-30 g were divided into six groups. The first group was KN as a non diabetic control group, KD as a diabetic control, KM as a group of diabetic mice treated with metformin, and NP, SP, and P as the treatment groups that were treated by using three different fractions from mangosteen pericarp extract, non polar, semi polar, and polar respectively. The induction of Diabetes mellitus was done by the injection of STZ, and the mice were given a high fat diet treatment to induce the hiperlipidemia condition using lard for three weeks. The blood cholesterol levels were measured in all groups before and after the injection of lard, and day 1, 7, and 14 of treatment as well. The serum MDA level as the indicator of lipid peroxidation were measured by using QuantiChrom TBARS Assay Kit (DTBA-100. The data of cholesterol levels were statistically analyzed by t-test, while the data of serum MDA levels were analyzed by variance analysis followed by Duncan test. The results showed that the polar fraction of mangosteen pericarp had effect to decrease the fasting blood cholesterol level in mice, however the non polar and semi polar fraction had no simmilar effect. All of the fractions has shown significant effect to decrease the serum MDA level in mice. Key words: cholesterol, diabetes mellitus, Garcinia mangostana, malondialdehyde (mda, obesity.

    Studies suggest that inflammation impairs reverse cholesterol transport (RCT). We investigated whether serum amyloid A (SAA) contributes to this impairment using an established macrophage-to-feces RCT model. Wild-type (WT) mice and mice deficient in SAA1.1 and SAA2.1 (SAAKO) were injected intraperitoneally with (3)H-cholesterol-labeled J774 macrophages 4 hr after administration of LPS or buffered saline. (3)H-cholesterol in plasma 4 hr after macrophage injection was significantly reduced in both WT and SAAKO mice injected with LPS, but this was not associated with a reduced capacity of serum from LPS-injected mice to promote macrophage cholesterol efflux in vitro. Hepatic accumulation of (3)H-cholesterol was unaltered in either WT or SAAKO mice by LPS treatment. Radioactivity present in bile and feces of LPS-injected WT mice 24 hr after macrophage injection was reduced by 36% (P < 0.05) and 80% (P < 0.001), respectively. In contrast, in SAAKO mice, LPS did not significantly reduce macrophage-derived (3)H-cholesterol in bile, and fecal excretion was reduced by only 45% (P < 0.05). Injection of cholesterol-loaded allogeneic J774 cells, but not syngeneic bone-marrow-derived macrophages, transiently induced SAA in C57BL/6 mice. Our study confirms reports that acute inflammation impairs steps in the RCT pathway and establishes that SAA plays only a minor role in this impairment.

    There is a lack of published work on RIs for newborn buffaloes. Establishing blood gas and serum biochemical RIs for newborn buffaloes is important for monitoring health. This study establishes blood gas and serum biochemical RIs of newborn buffaloes. Twenty-eight newborn buffaloes, 10-30 days old, were selected. Thirty blood biochemical variables were analyzed. The Anderson-Darling test was used to assess the normality of the distribution. The Dixon test and the Tukey test were used to identify outliers. The RI and 90% CI were determined using standard and robust methods and the Box-Cox transformation. A total of 30 RIs for healthy buffalo calves have been reported in this study. RIs for blood gas variables were reported for pH, partial pressure of oxygen (pO 2 ), partial pressure of carbon dioxide (pCO 2 ), saturation of O 2 (SO 2 ), bicarbonate (cHCO 3 - ), base excess (BE), total carbon dioxide (ctCO 2 ), and anion gap (AG). RIs for serum biochemical variables were reported for glucose (GLU), direct bilirubin (DB), total bilirubin (TB), AST, ALP, GGT, CK, LDH, creatinine (CREA), urea, cholesterol (CHOL), triglycerides (TG), Ca, P, Mg, Na, K, iCa, Cl, iron, total protein (TP), and albumin (ALB).

    Serum β 2 -microglobulin (β 2 -MG) was tested by radioimmunoassay in 149 donors' and 54 healthy volunteers' blood. The results were 203 +- 33.0 nmol/l and 176 +- 26.2 nmol/l, respectively. There was significant difference statistically between them (P 2 -MG content. In order to increase the quality of donated blood and to keep the health of blood donor, it is suggested that the high content of serum β 2 -MG is the indicator of too frequent blood donating. The results also showed that the content of β 2 -MG in donor's blood is not a normal reference value

    The aim of our research was the quantification of interfering properties of the haemostatic drug Dicynone (ethamsylate) in serum creatinine, uric acid, cholesterol, and triglyceride assays using the Trinder reaction. Blood from patients was collected before and 15 minutes after administration of 500 mg Dicynone dose i.v. and the above mentioned analytes were quantified using Roche assays (Cobas 8000). In our in vitro experiment, we measured concentrations of the analytes in pooled serum aliquots with final concentrations of Dicynone additions 0, 30, 60, 150, and 300 mg/L. Aliquots with 60 mg/L Dicynone were also measured at 2, 6, and 8 hours after initial measurement when stored in 22 degrees C and 4 degrees C for comparison. Concentrations of the measured analytes in samples from patients administered with a 500 mg dose of Dicynone were lower in all cases (n = 10) when compared to values in samples taken immediately before treatment. The in vitro samples showed that considerable negative interference occurred even with the low concentrations of Dicynone additions (30 and 60 mg/L), showing the strongest negative interference in creatinine values, followed by uric acid, triglycerides, and cholesterol. Using in vitro samples, we showed strong time and temperature dependence on Dicynone interference. We found and proved significant negative interference of the drug Dicynone (ethamsylate) in the clinical analysis of blood using in vivo and in vitro experiments. Furthermore, we observed a change of this effect in serum matrix over time and at different storage temperatures.

    Blood donation results in a substantial iron loss and subsequent mobilization from body stores. Chronic iron deficiency is a well-recognized complication of regular blood donation. The present study conducted to compare the level of serum ferritin, serum iron, total iron binding capacity (TIBC) and percentage transferrin saturation in different ABO and Rhesus type blood groups among the voluntary blood donors of Bangladesh. The present prospective study included 100 healthy voluntary donors attending at Department of Blood Transfusion, Dhaka Medical College, Dhaka between the periods of July 2013 to Jun 2014. From each donor 10mL venous blood sample was taken and divided into heparinized and non-heparinized tubes for determination of hemoglobin (Hb), hematocrit (Hct), serum iron (SI), total iron binding capacity (TIBC) and serum ferritin by standard laboratory methods. Percentage of transferrin saturation (TS) calculated from serum iron and TIBC. Data were analyzed with SPSS (version 16) software and comparisons between groups were made using student's t-test and one way ANOVA. In the present study mean±SD of age of the respondents was 27.2±6.5 years with a range of 18 to 49 years and 81.0% were male and 19.0% were female. Among the donors 18.0% had blood group A, 35.0% had blood group B, 14.0% had blood group AB and 33.0% had blood group O. Among the donors 91.0% had rhesus positive and 9.0% had rhesus negative. Donors with blood group O had lowest haemoglobin, serum iron and transferring saturation levels. Donors with blood group A had highest TIBC level. Donors with blood group B had lowest serum ferritin level. An independent samples 't' test showed statistically significant difference in serum ferritin and percentage transferrin saturation between blood group AB and blood group O and in percentage transferrin saturation between blood group B and blood group O. One way ANOVA showed that there is no significant difference in haemoglobin, serum iron, serum

    Isoniazid is the first-line medication in the prevention and treatment of tuberculosis. Isoniazid is known to have a biphasic effect on the inhibition–induction of CYP2E1 and is also considered to be involved in isoniazid-induced hepatotoxicity. However, the full extent and mechanism of involvement of CYP2E1 in isoniazid-induced hepatotoxicity remain to be thoroughly investigated. In the current study, isoniazid was administered to wild-type and Cyp2e1-null mice to investigate the potential toxicity of isoniazid in vivo. The results revealed that isoniazid caused no hepatotoxicity in wild-type and Cyp2e1-null mice, but produced elevated serum cholesterol and triglycerides, and hepatic bile acids in wild-type mice, as well as decreased abundance of free fatty acids in wild-type mice and not in Cyp2e1-null mice. Metabolomic analysis demonstrated that production of isoniazid metabolites was elevated in wild-type mice along with a higher abundance of bile acids, bile acid metabolites, carnitine and carnitine derivatives; these were not observed in Cyp2e1-null mice. In addition, the enzymes responsible for bile acid synthesis were decreased and proteins involved in bile acid transport were significantly increased in wild-type mice. Lastly, treatment of targeted isoniazid metabolites to wild-type mice led to similar changes in cholesterol, triglycerides and free fatty acids. These findings suggest that while CYP2E1 is not involved in isoniazid-induced hepatotoxicity, while an isoniazid metabolite might play a role in isoniazid-induced cholestasis through enhancement of bile acid accumulation and mitochondria β-oxidation. -- Highlights: ► Isoniazid metabolites were elevated only in wild-type mice. ► Isoniazid caused no hepatotoxicity in wild-type and Cyp2e1-null mice. ► Isoniazid elevated serum cholesterol and triglycerides, and hepatic bile acids. ► Bile acid transporters were significantly decreased in isoniazid-treated mice.

    A chart review covering the first 5 years of clinical experience with a combined dietary and exercise intervention program for the reduction of hypercholesterolemia at the National Aeronautics and Space Administration headquarters demonstrated the program's success in maintaining high-density lipoprotein cholesterol (HDL-C) levels while significantly lowering total serum cholesterol levels. This combined program also resulted in improved ratios of total serum cholesterol to HDL-C and lowered levels of low-density lipoprotein cholesterol, thus further reducing the risk for cardiovascular disease. The National Aeronautics and Space Administration Cardiovascular Risk Reduction Program was developed after it was determined that although dietary intervention alone improved total cholesterol levels, it often resulted in a more than proportionate decrease in HDL-C and a worsening of the ratio of cholesterol to HDL-C. An approach was needed that would positively affect all factors of the lipid profile. The findings from the program indicate that reduction of cardiovascular risk can be accomplished easily and effectively at the worksite through dietary intervention, personal monitoring, and a reasonable exercise program.

    A lower serum cholesterol level was recently shown to be one of the causes of stroke in an epidemiological study. Spontaneously hypertensive rats stroke-prone (SHRSP) have lower serum cholesterol levels than normotensive Wistar-Kyoto rats (WKY). To elucidate the mechanisms responsible for the lower serum cholesterol levels in SHRSP, we determined whether the amounts of cholesterol biosynthetic enzymes or the receptor and transporter involved in cholesterol uptake and efflux in the liver were altered in SHRSP. When the mRNA levels of seven cholesterol biosynthetic enzymes were measured using real-time polymerase chain reaction (PCR), farnesyl pyrophosphate synthase and squalene epoxidase (SQE) levels in the liver of SHRSP were significantly lower than those in WKY. SQE protein levels were significantly reduced in tissues other than the brain of SHRSP. No significant differences were observed in low-density lipoprotein (LDL) receptor (uptake of serum LDL-cholesterol) or ATP-binding cassette transporter A1 (efflux of cholesterol from the liver/formation of high-density lipoprotein (HDL)) protein levels in the liver and testis between SHRSP and WKY, whereas scavenger receptor class B type 1 (SRB1: uptake of serum HDL-cholesterol) protein levels were higher in the livers of SHRSP. These results indicated that the lower protein levels of SQE and higher protein levels of SRB1 in the liver were involved in the reduced serum cholesterol levels in SHRSP.

    2013-01-01

    Background Previous data suggested that intake of sodas and other acid beverages might be associated with increased levels of serum triglycerides, lowered HDL cholesterol, and increased formation of mono unsaturated fatty acids, which are the preferred ones for triglyceride synthesis. The present work is an extension of these studies. Methods Thirty male rats were divided into 3 groups. All groups were given the same food, but various beverages: water (W), ammonium chloride, 200 mmol/L (AC), or sodium bicarbonate, 200 mmol/L (SB). Serum triglycerides, HDL cholesterol, and the fatty acid distribution in total serum lipids were determined. Delta9-desaturase in serum lipids was estimated by the ratio of palmitoleic to palmitic acid, and by the oleic/stearic acid ratio. Correlation and ANOVA were used to study associations and group differences. Results After 3 weeks, the AC group had higher triglyceride concentration and higher Delta9 desaturase indexes, but lower serum HDL and body weight as compared with the SB and W groups. In each of the groups, the oleic acid/stearic acid ratio correlated positively with serum triglycerides; in the pooled group the correlation coefficient was r = 0.963, ptriglycerides, and lowered HDL cholesterol concentration, thereby possibly contributing to explain the increased triglyceride concentration previously observed in subjects with a frequent intake of acid beverages, such as sodas containing carbonic acid, citric acid, and phosphoric acid.

    A simple sensitive method for the determination of the initial rate of the reaction of lecithin-cholesterol acyltransferase by equilibrating [ 3 H]cholesterol with unesterified cholesterol of human serum is described. The resulting serum is incubated for various time periods at 37 degrees C and the increase of the label in the cholesterol ester fraction is measured. The labeling is effected by a fids at 37 degrees C and the increase of the label in the cholesterol ester fraction is measured. The labeling is effected by a filter paper method in which a paper strip containing the labeled cholesterol is placed in serum at 4 degrees C, thereby preventing the formation of labeled cholesterol esters by the action of the enzyme. The rate of the reaction was linear up to 30 min

    Low-density lipoprotein cholesterol (LDL-c) and high-density lipoprotein cholesterol (HDL-c), which are components of total cholesterol, have each been suggested to be linked to the risk of sudden cardiac death (SCD). However, the relationship between LDL-c/HDL-c ratio and the risk of SCD has not been previously investigated. We aimed to assess the associations of LDL-c, HDL-c, and the ratio of LDL-c/HDL-c with the risk of SCD. Serum lipoprotein concentrations were assessed at baseline in the Finnish Kuopio Ischemic Heart Disease prospective cohort study of 2,616 men aged 42-61 years at recruitment. Hazard ratios (HRs) (95% confidence intervals [CI]) were assessed. During a median follow-up of 23.0 years, a total of 228 SCDs occurred. There was no significant evidence of an association of LDL-c or HDL-c with the risk of SCD. In analyses adjusted for age, examination year, body mass index, systolic blood pressure, smoking, alcohol consumption, physical activity, years of education, diabetes, previous myocardial infarction, family history of coronary heart disease, and serum high sensitivity C-reactive protein, there was approximately a two-fold increase in the risk of SCD (HR 1.94, 95% CI 1.21-3.11; p=0.006), comparing the top (>4.22) versus bottom (≤2.30) quintile of serum LDL-c/HDL-c ratio. In this middle-aged male population, LDL-c or HDL-c was not associated with the risk of SCD. However, a high serum LDL-c/HDL-c ratio was found to be independently associated with an increased risk of SCD. Further research is warranted to understand the mechanistic pathways underlying this association.

  6. Blood cholesterol and vascular mortality by age, sex, and blood pressure: a meta-analysis of individual data from 61 prospective studies with 55,000 vascular deaths

    BACKGROUND: Age, sex, and blood pressure could modify the associations of total cholesterol (and its main two fractions, HDL and LDL cholesterol) with vascular mortality. This meta-analysis combined prospective studies of vascular mortality that recorded both blood pressure and total cholesterol.......65-0.68]), and a sixth (0.83 [0.81-0.85]) lower IHD mortality in both sexes at ages 40-49, 50-69, and 70-89 years, respectively, throughout the main range of cholesterol in most developed countries, with no apparent threshold. The proportional risk reduction decreased with increasing blood pressure, since the absolute......). Total cholesterol was weakly positively related to ischaemic and total stroke mortality in early middle age (40-59 years), but this finding could be largely or wholly accounted for by the association of cholesterol with blood pressure. Moreover, a positive relation was seen only in middle age and only...

    Previous research on serum total cholesterol and suicidality has yielded conflicting results. Several studies have reported a link between low serum total cholesterol and suicidality, whereas others have failed to replicate these findings, particularly in patients with major affective disorders. These discordant findings may reflect the fact that studies often do not distinguish between patients with bipolar and unipolar depression; moreover, definitions and classification schemes for suicide attempts in the literature vary widely. Subjects were patients with one of the three major psychiatric disorders commonly associated with suicide: schizophrenia, bipolar affective disorder, and major depressive disorder (MDD). We compared serum lipid levels in patients who died by suicide (82 schizophrenia, 23 bipolar affective disorder, and 67 MDD) and non-suicide controls (200 schizophrenia, 49 bipolar affective disorder, and 175 MDD). Serum lipid profiles did not differ between patients who died by suicide and control patients in any diagnostic group. Our results do not support the use of biological indicators such as serum total cholesterol to predict suicide risk among patients with a major psychiatric disorder.

    Cholesterol oxidation products (COPs) have been considered as specific in vivo markers of oxidative stress. In this study, an increased oxidative status was induced in Wistar rats by feeding them a high-fat diet (cafeteria diet). Another group of animals received the same diet supplemented with a combination of two different antioxidants, ascorbic acid (100 mg/kg rat/day) and sodium selenite (200 microg/kg rat/day) and a third group fed on a control diet. Total and individual COPs analysis of the different diets showed no differences among them. At the end of the experimental trial, rats were sacrificed and serum cholesterol, triglycerides and COPs were measured. None of the diets induced changes in rats body weight, total cholesterol and triglycerides levels. Serum total COPs in rats fed on the high-fat diet were 1.01 microg/ml, two times the amount of the control rats (0.47 microg/ml). When dietary antioxidant supplementation was given, serum total COPs concentration (0.44 microg/ml) showed the same levels than those of the rats on control diet. 7beta-hydroxycholesterol, formed non-enzymatically via cholesterol peroxidation in the presence of reactive oxygen species, showed slightly lower values in the antioxidant-supplemented animals compared to the control ones. This study confirms the importance of dietary antioxidants as protective factors against the formation of oxysterols.

    Full Text Available Studies suggest that inflammation impairs reverse cholesterol transport (RCT. We investigated whether serum amyloid A (SAA contributes to this impairment using an established macrophage-to-feces RCT model. Wild-type (WT mice and mice deficient in SAA1.1 and SAA2.1 (SAAKO were injected intraperitoneally with 3H-cholesterol-labeled J774 macrophages 4 hr after administration of LPS or buffered saline. 3H-cholesterol in plasma 4 hr after macrophage injection was significantly reduced in both WT and SAAKO mice injected with LPS, but this was not associated with a reduced capacity of serum from LPS-injected mice to promote macrophage cholesterol efflux in vitro. Hepatic accumulation of 3H-cholesterol was unaltered in either WT or SAAKO mice by LPS treatment. Radioactivity present in bile and feces of LPS-injected WT mice 24 hr after macrophage injection was reduced by 36%   (P<0.05 and 80%   (P<0.001, respectively. In contrast, in SAAKO mice, LPS did not significantly reduce macrophage-derived 3H-cholesterol in bile, and fecal excretion was reduced by only 45%   (P<0.05. Injection of cholesterol-loaded allogeneic J774 cells, but not syngeneic bone-marrow-derived macrophages, transiently induced SAA in C57BL/6 mice. Our study confirms reports that acute inflammation impairs steps in the RCT pathway and establishes that SAA plays only a minor role in this impairment.

    Nutrient levels in buckwheats that were maximized in day 8 sprouts (D8SP) included total phenolics, quercetin, and l-ascorbic acid, whereas those of oxalic, malic, tartaric, and citric acids, rutin, and gamma-aminobutyric acid (GABA) were found to reach maximum levels on day 10. Ethanolic extract of D8SP (2.5 mg/mL) revealed potent free-radical scavenging (FRS) and antioxidative (ANO) capabilities. However, its Fe2+-chelating capability was only moderate. To further study the hypolipidemic activity of D8SP, 36 Syrian hamsters were grouped into six groups and fed for 28 days, respectively, with (i) control meal, (ii) high fat plus high cholesterol meal, (iii) high fat plus high cholesterol plus 2.5% of buckwheat seeds, (iv) high fat plus high cholesterol plus 25% of buckwheat seeds, (v) high fat plus high cholesterol plus 2.5% of D8SP, and (vi) high fat plus high cholesterol plus 25% of D8SP. High seed meal prominently enhanced body weight gain, whereas high sprout meal exhibited the highest feed efficiency. Ratios of liver/body weight (L/B) were significantly lowered by all BS meals. Although low seed meal reduced serum total cholesterol (TC) levels (pcholesterol (LDL-C) were significantly suppressed by all buckwheat meals (pcholesterol (HDL-C) levels were increased, however, insignificantly. Nutraceutically more meaningful is that both LDL-C/HDL-C and TC/HDL-C ratios were significantly lowered (p<0.01). Apparently, hepatic TC levels were significantly reduced, whereas hepatic TG levels were totally unaffected. Conclusively, sprouting triggers a variety of nutritional changes in buckwheats. Day 8 sprouts, consisting of high polyphenolic and moderate quercetin contents, are nutraceutically maximized when hypocholesterolemic, hypotriglyceridemic, and antioxidative activities are concerned.

    Full Text Available Background and Aims: Studies in South Asian population show that low maternal vitamin B12 associates with insulin resistance and small for gestational age in the offspring. Low vitamin B12 status is attributed to vegetarianism in these populations. It is not known whether low B12 status is associated with metabolic risk of the offspring in whites, where the childhood metabolic disorders are increasing rapidly. Here, we studied whether maternal B12 levels associate with metabolic risk of the offspring at birth. Methods: This is a cross-sectional study of 91 mother-infant pairs (n = 182, of white Caucasian origin living in the UK. Blood samples were collected from white pregnant women at delivery and their newborns (cord blood. Serum vitamin B12, folate, homocysteine as well as the relevant metabolic risk factors were measured. Results: The prevalence of low serum vitamin B12 (<191 ng/L and folate (<4.6 μg/L were 40% and 11%, respectively. Maternal B12 was inversely associated with offspring’s Homeostasis Model Assessment 2-Insulin Resistance (HOMA-IR, triglycerides, homocysteine and positively with HDL-cholesterol after adjusting for age and BMI. In regression analysis, after adjusting for likely confounders, maternal B12 is independently associated with neonatal HDL-cholesterol and homocysteine but not triglycerides or HOMA-IR. Conclusions: Our study shows that low B12 status is common in white women and is independently associated with adverse cord blood cholesterol.

    Our aim was to assess the effects of dietary iron, and the compound capsaicin, on hemoglobin as well as metabolic indicators including blood glucose, cholesterol, triglycerides, insulin, and glucose tolerance. Our animal model was the Wistar rat, fed a chow diet, with or without experimentally induced diabetes. Diabetic males were fed control, low, or high-iron diets, the latter, with or without capsaicin. Healthy rats were fed identical diets, but without the capsaicin supplement. We then measured the parameters listed above, using the Student t-test and ANOVA, to compare groups. Healthy rats fed a low-iron diet exhibited significantly reduced total cholesterol and triglyceride levels, compared with rats fed a control diet. Significantly reduced blood lipid was also provoked by low dietary iron in diabetic rats, compared with those fed a control diet. Insulin, and glucose tolerance was only improved in healthy rats fed the low-iron diet. Significant increases in total cholesterol were found in diabetic rats fed a high-iron diet, compared with healthy rats fed the same diet, although no statistical differences were found for triglycerides. Hemoglobin levels, which were not statistically different in diabetic versus healthy rats fed the high-iron diet, fell when capsaicin was added. Capsaicin also provoked a fall in the level of cholesterol and triglycerides in diabetic animals, versus diabetics fed with the high iron diet alone. In conclusion, low levels of dietary iron reduced levels of serum triglycerides, hemoglobin, and cholesterol, and significantly improved insulin, and glucose tolerance in healthy rats. In contrast, a high-iron diet increased cholesterol significantly, with no significant changes to triglyceride concentrations. The addition of capsaicin to the high-iron diet (for diabetic rats) further reduced levels of hemoglobin, cholesterol, and triglycerides. These results suggest that capsaicin, may be suitable for the treatment of elevated hemoglobin

    Background: Hyperuricemia can cause serious health problems including renal insufficiency. Hyperuricemia is associated with many diseases including Hypertension, Diabetes Mellitus, Hypertriglyceridemia and Obesity. Objective of the present study was to study the Association of Serum Uric Acid with Blood Urea and Serum Creatinine. Methods: Eighty subjects, aged above 40, having blood urea more than 40 mg/dl and serum Creatinine more than 1.3 mg/dl were selected. 52.5 % subjects were male. Eighty subjects were selected as control group matching the age and sex with study group with normal blood urea and serum Creatinine. Results: Serum Uric Acid was found to be raised in 33 patients. Mean Serum Uric Acid value was 6.98+-2.021 in males (p<0.05) and 5.054+-2.324 in females (p<0.05). Conclusion: Serum Uric Acid is raised in patients with impaired renal function (p<0.05). Levels of increased Serum Uric Acid were not significantly associated with the cause of renal disease. (author)

    The exogenously hypercholesterolemic (ExHC) rat is a strain segregated from SD rats with a high response to dietary cholesterol. To understand the underlying mechanism(s) for this hypercholesterolemia, the interactive effects of dietary fatty acid and the susceptibility of rats to dietary cholesterol on the serum cholesterol concentration and hepatic mRNA abundance of the low-density lipoprotein (LDL) receptor, cholesterol 7alpha-hydroxylase (7alpha-hydroxylase) and 3-hydroxyl-3methylglutaryl (HMG) CoA reductase were examined. Both strains were fed on a diet supplemented with 10% each of olive, safflower or coconut oil with or without the addition of 1% cholesterol for one week. The ExHC rats fed on olive, safflower and coconut oil in combination with cholesterol respectively resulted in a 3.5-, 2.0- and 2.1-fold higher serum cholesterol concentration than that in the animals fed on the corresponding dietary fats without any supplementation of cholesterol (p safflower oil-containing diet supplemented with cholesterol resulted in a higher mRNA abundance of the LDL receptor and 7alpha-hydroxylase than in the corresponding fat-fed rats without cholesterol (p<0.05). There was no dietary cholesterol-dependent change of mRNA abundance in either strain fed on olive or coconut oil, except for a decreased abundance of HMG CoA reductase mRNA in the olive oil-fed ExHC rats and coconut oil-fed Sprague-Dawley (SD) rats (p<0.05). These results indicate that the hepatic mRNA abundance of the LDL receptor and of 7alpha-hydroxylase depended on the dietary combination of cholesterol and a fatty acid and suggest that a linoleic acid-rich diet may alleviate exogenous hypercholesterolemia by activating the process involved in the hepatic uptake and biliary excretion of serum cholesterol.

    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.

    Cholesterol level (CL) is growing concerned as health issue in human health since it is considered one of the causes in heart diseases. A study of cholesterol level can provide insight about its nature and characteristics. A cross-sectional study. National Health and Nutrition Examination Survey (NHANS) II was conducted on a probability sample of approximately 28,000 persons in the USA and cholesterol level is obtained from laboratory results. Samples were selected so that certain population groups thought to be at high risk of malnutrition. Study included 11,864 persons for CL cases with 9,602 males and 2,262 females with races: whites, blacks, and others. Non-parametric statistical tests and goodness of fit test have been used to identify probability distributions. The study concludes that the cholesterol level exhibits significant racial and gender differences in terms of probability distributions. The study has concluded that white people are relatively higher at risk than black people to have risk line and high risk cholesterol. The study clearly indicates that black males normally have higher cholesterol. Females have lower variation in cholesterol than males. There exists gender and racial discrepancies in cholesterol which has been identified as lognormal and gamma probability distributions. White individuals seem to be at a higher risk of having high risk cholesterol level than blacks. Females tend to have higher variation in cholesterol level than males.

    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.

    Objective: To investigate the prevalence of intrahepatic cholestasis during pregnancy and the relationship between levels of serum CG and blood lipids. Methods: Serum CG, blood lipid and liver function profile were examined in 2040 women with pregnancy during the second or third trimester. Among these pregnant women, 57 were diagnosed as with intrahepatic cholestasis. Blood lipids (TG, cholesterol, HDL, LDL) and ALP levels in 50 of the 57 pregnant women were studied and compared with those in 50 otherwise normal pregnant women as controls. Results: Serum CG levels were above normal range in 372 of the 2040 pregnant women (18.5%). Fifty seven of these 372 pregnant women were confirmed to be with intrahepatic cholestasis (2.8% of the 2040 pregnancies). The TG, cholesterol, LDL contents and ALP levels in the pregnant women with intrahepatic cholestasis were significantly higher (P 0.05) than those in controls. Conclusion: Intrahepatic cholestasis developed in a substantial proportion of pregnant women (2.8% in this study) and should be carefully monitored due to possible damage to the fetus. Serum CG was shown to be an early and sensitive marker for the diagnosis of intrahepatic cholestasis. Changes of blood lipid and ALP levels were related to disease status. (authors)

    Full Text Available Hypercholesterolemia is one of the risk factors of cardiovascular diseases. High blood cholesterol affects the general health and increases the mortality rate of cardiovascular diseases. High levels of cholesterol in the diet increases LDL levels and decreases the activity of LDL receptors in the liver. Oxidation of vascular LDL lipoproteins increases the development of atherosclerosis. Previous studies have indicated that consumption of antioxidants decreases hypercholesterolemia. This study evaluates the effect of vitamin E supplementation on blood lipid levels in high cholesterol-fed rats. In this experimental study, three groups of male rats (n=10 for each group were used. The control group received basic diet and one of the other two groups received a diet containing one percent cholesterol and while the other received the same diet plus vitamin E supplement (2500 IU/kg in dry matter of the diet for one month. After determining the values of TC, LDL, VLDL, HDL and TG the results indicated that in rats fed with 1% cholesterol apart from HDL and VLDL the other lipids had increased significantly compared with the control group (p

    Obesity is increasing in developed as well as in developing countries. This analytical cross sectional study was carried out to document the relation between blood pressure, serum creatinine and body mass index in female and to assess potential health differences among obese female and normal weight female. This study was done in the Department of Physiology, Mymensingh Medical College, Mymensingh, Bangladesh from July 2012 to June 2013. Seventy female persons volunteered as subjects. Among them 35 were within normal weight (BMI 18.5-24.9kg/m²) and 35 were obese (BMI≥30kg/m²). Non probability purposive type of sampling technique was used to select the subjects. Measurement of body mass index and blood pressure were done as per procedure. Serum creatinine level was estimated by enzymatic colorimetric method. The results were calculated and analyzed by using SPSS (statistical package for social science, version 17.0), scientific electronic calculator and simultaneously with a computer assisted program like Microsoft excel. Unpaired 't' test was applied to find the significance of difference regarding serum creatinine and blood pressure levels in obese female. The value of p was 1% to indicate highly significant and 5% to indicate simply significant or statistically significant. The mean±SE of systolic blood pressure, diastolic blood pressure and serum creatinine levels were 135.71±1.58mmHg, 88.74±0.95mmHg and 1.03±0.01mg/dl respectively; significant at 1% level for obese group of BMI (phigh BMI is significantly related to increased levels of serum creatinine & blood pressure in obese female which indicate the obese subjects are prone to cardiovascular & metabolic risk.

    The effects of structured triglycerides containing one long chain fatty acid (oleic acid, C18:1) and one short chain saturated fatty acid (caprylic acid, 8:0) on lipidemia, liver and aortic cholesterol, and fecal neutral sterol excretion were investigated in male Golden Syrian hamsters fed a hypercholesterolemic regimen consisting of 89.9% commercial ration to which was added 10% coconut oil and 0.1% cholesterol (w/w). After 2 weeks on the HCD diet, the hamsters were bled, following an overnight fast (16 h) and placed into one of three dietary treatments of eight animals each based on similar plasma cholesterol levels. The hamsters either continued on the HCD diet or were placed on diets in which the coconut oil was replaced by one of two structured triglycerides, namely, 1(3),2-dicaproyl-3(1)-oleoylglycerol (OCC) or 1,3-dicaproyl-2-oleoylglycerol (COC) at 10% by weight. Plasma total cholesterol (TC) in hamsters fed the OCC and COC compared to the HCD were reduced 40% and 49%, respectively (Pstructured triglyceride oils had lower blood cholesterol levels and lower aortic accumulation of cholesterol compared to the control fed hamsters.

    Full Text Available The Turkish Van cat originates from eastern Turkey. One of the characteristic features of Van cats is the colour of their eyes, which can be both eyes blue, both eyes amber or one eye blue and the other amber. Serum essential trace, macro and industrial element concentrations of Van cats (n = 47 according to sex, age, hair length and eye colour differences were investigated. Serum aluminium, arsenic, boron, barium, cobalt, chromium, copper, gallium, indium, iron, lead, lithium, manganese, nickel, selenium, silver, sulphur, strontium, vanadium and zinc were measured with ICP-OES plasma optical atomic emission spectrometer. In result, serum aluminium, barium, copper, manganese and strontium levels in male cats were found higher (p p p p > 0.05 found in the age and hair length groups. Our results indicate that several of the blood serum elements of Van cats may be related to their eye colours and sex differences.

    The purpose of this study was to examine the relationship between serum total cholesterol levels and certification eligibility for long-term care insurance in elderly Japanese individuals. The Tsurugaya Project was a comprehensive geriatric assessment conducted for community-dwelling elderly individuals aged ≥70 years in the Tsurugaya area, Sendai, Japan. Of the 2,925 inhabitants, 958 subjects participated in the Tsurugaya Project. For this analysis, we used 827 subjects who gave informed consent and were not qualified for long-term care insurance at the time of the baseline survey. Subjects were followed up for 6 years. We classified the subjects into 4 quintiles and used the fourth quintile (212-230 mg/dL) as a reference for statistical analysis. We used Cox proportional hazards model to estimate the hazard ratios (HRs) and 95% confidence intervals (CIs) of certification eligibility for long-term care insurance according to total cholesterol levels in serum. During 6 years of follow-up, a total of 214 subjects were qualified for long-term care insurance certification. The lowest serum total cholesterol level (care insurance certification. Compared with the fourth quintile, multivariate HRs (95%CIs) of long-term care insurance certification were 1.91 (1.23-2.98), 1.36 (0.85-2.18), 0.99 (0.62-1.56), 1.38 (0.88-2.17), for total cholesterol levels were significantly associated with increased eligibility for long-term care insurance certification even after adjusting for a variety of confounding factors.

    level of S-protein-bound form of the terminal complex (SC5b-9). However, liposome-induced rise of SC5b-9 was significantly suppressed when serum HDL cholesterol levels increased by 30%. Increase of serum LDL to levels similar to that observed in heterozygous familial hypercholesterolemia also suppressed......Intravenously infused liposomes may induce cardiopulmonary distress in some human subjects, which is a manifestation of "complement activation-related pseudoallergy." We have now examined liposome-mediated complement activation in human sera with elevated lipoprotein (LDL and HDL) levels, since...... abnormal or racial differences in serum lipid profiles seem to modulate the extent of complement activation and associated adverse responses. In accordance with our earlier observations, cholesterol-rich (45 mol% cholesterol) liposomes activated human complement, as reflected by a significant rise in serum...

    BACKGROUND: Age, sex, and blood pressure could modify the associations of total cholesterol (and its main two fractions, HDL and LDL cholesterol) with vascular mortality. This meta-analysis combined prospective studies of vascular mortality that recorded both blood pressure and total cholesterol...... pressures, is unexplained, and invites further research. Nevertheless, there is conclusive evidence from randomised trials that statins substantially reduce not only coronary event rates but also total stroke rates in patients with a wide range of ages and blood pressures....... and blood pressure.

    The purpose of this study was to determine the nutritional value of diets with protein from two marine species (Haliotis tuberculata and Anemonia viridis) as compared to a high-quality protein reference based on casein or casein supplemented with olive oil. We also investigated the effects of these diets on serum lipid levels. Male rats were fed these diets for 23 days. Protein quality indicators (true digestibility, net protein utilization, biological value) were similar to those obtained for casein-based feeds except for lower true digestibility and net protein utilization values for the Anemonia viridis feed. HDL-cholesterol level was significantly higher (p < 0.05) in the groups fed marine species or casein supplemented with olive oil than in the casein group. Total-cholesterol level was higher in the group fed Haliotis tuberculata fed than in the other groups. These results suggest that these marine species are a good protein source, and that they may have positive effects on serum cholesterol level.

    Biosphere 2 is a 3.15-acre space containing an ecosystem that is energetically open (sunlight, electric power, and heat) but materially closed, with air, water, and organic material being recycled. Since September 1991, eight subjects (four women and four men) have been sealed inside, living on food crops grown within. Their diet, low in calories (average, 1780 kcal/day; 1 kcal = 4.184 kJ), low in fat (10% of calories), and nutrient-dense, conforms to that which in numerous animal experiments has promoted health, retarded aging, and extended maximum life span. We report here medical data on the eight subjects, comparing preclosure data with data through 6 months of closure. Significant changes included: (i) weight, 74 to 62 kg (men) and 61 to 54 kg (women); (ii) mean systolic/diastolic blood pressure (eight subjects), 109/74 to 89/58 mmHg (1 mmHg = 133 Pa); (iii) total serum cholesterol, from 191 +/- 11 to 123 +/- 9 mg/dl (mean +/- SD; 36% mean reduction), and high density lipoprotein, from 62 +/- 8 to 38 +/- 5 (risk ratio unchanged); (iv) triglyceride, 139 to 96 mg/dl (men) and 78 to 114 mg/dl (women); (v) fasting glucose, 92 to 74 mg/dl; (vi) leukocyte count, 6.7 to 4.7 x 10(9) cells per liter. We conclude that drastic reductions in cholesterol and blood pressure may be instituted in normal individuals in Western countries by application of a carefully chosen diet and that a low-calorie nutrient-dense regime shows physiologic features in humans similar to those in other animal species.

    Several studies have focused on the effects of calcium intake on serum lipid concentrations in postmenopausal women. However, many premenopausal women are taking calcium supplements in China. To our knowledge, no studies have assessed whether the effects of calcium supplementation on blood lipids are similar between premenopausal and postmenopausal women. We assessed the effects of calcium supplementation on blood lipid concentrations in premenopausal and postmenopausal women with dyslipidemia. A total of 190 premenopausal women (30-40 y old) and 182 postmenopausal women (50-60 y old) with dyslipidemia were given 800 mg Ca/d or a placebo for 2 y in a double-blind, randomized, placebo-controlled trial. Blood pressure, fasting glucose and serum lipid concentrations, carotid intima-media thickness (CIMT), dietary nutrient intakes, and physical activity levels were determined at baseline and after 2 y. There was a significant interaction between calcium supplementation and menopausal status on serum cholesterol concentrations (P women (P women with dyslipidemia increases serum total cholesterol concentrations and CIMT. In postmenopausal women with dyslipidemia, calcium supplements should be prescribed with caution. This trial was registered at http://www.chictr.org/cn/ as ChiCTR-TRC-12002806.

    Lactic-fermented egg white (LE), produced by lactic acid fermentation of egg white, is an easy-to-consume form of egg white. Here we assessed the effect of daily consumption of LE for 8 weeks on serum total cholesterol (TC) levels. The study followed a double-blind, parallel-arm design and included 88 adult men with mild hypercholesterolemia (mean ± standard error) serum TC levels, 229 ± 1.6 mg/dL; range, 204-259 mg/dL). The subjects were randomly divided into three groups, which consumed LE containing 4, 6, or 8 g of protein daily for 8 weeks. Blood samples were collected before starting LE consumption (baseline) and at 4 and 8 weeks to measure serum TC and low-density lipoprotein cholesterol (LDL-C) levels. After 8 weeks of consumption, serum TC levels in the 8 g group decreased by 11.0 ± 3.7 mg/dL, a significant decrease compared to baseline (p < 0.05) and a significantly greater decrease than for the 4 g group (3.1 ± 3.4 mg/dL; p < 0.05). Serum LDL-C levels in the 8 g group decreased by 13.7 ± 3.1 mg/dL, again a significant decrease compared with baseline (p < 0.05) and a significantly greater decrease than that for the 4 g group (2.1 ± 2.9 mg/dL; p < 0.05). Consumption of LE for 8 weeks at a daily dose of 8 g of proteins reduced serum TC and LDL-C levels in men with mild hypercholesterolemia, suggesting this may be effective in helping to prevent arteriosclerotic diseases. This clinical trial was retrospectively registered with the Japan Medical Association Center for Clinical Trials, (JMA-IIA00279; registered on 13/03/2017; https://dbcentre3.jmacct.med.or.jp/JMACTR/App/JMACTRE02_04/JMACTRE02_04.aspx?kbn=3&seqno=6530 ).

    Phytosterols are recommended in combination with diet therapy to reduce elevated LDL-cholesterol level. Meta-analyses indicate a 10% reduction in LDL-cholesterol from intake of approximately 2 g phytosterols/d incorporated into fat-based foods. However, the cholesterol lowering effect from capsules containing phytosterols is less documented. The pre-specified primary endpoint of the present study was to investigate the effect of capsules with phytosterols on circulating LDL-cholesterol in patients with mild to moderate hypercholesterolemia. In a double-blinded, randomized, placebo-controlled crossover study, 41 men and women were randomized into two four-weeks intervention periods with softgel capsules containing either phytosterols (2.0 g/d) or sunflower oil. There was a three-weeks washout period between the intervention periods. No significant difference in total- or LDL-cholesterol between the phytosterol and the placebo period were observed after four weeks intervention (0.0 mmol/L (95%CI: -0.3 to 0.2), P = 0.74 and -0.1 mmol/L (95%CI: -0.3 to 0.1), P = 0.32, respectively). Daily intake of capsules containing 2 g phytosterols did not reduce total- or LDL-cholesterol significantly in a highly relevant target group for the use of phytosterol products. The present results may emphasize the importance of choosing a suitable dosage-delivery system in order to achieve optimal cholesterol lowering effect.

    Using disk electrophoresis in the polyacrylamide gel, blood serum proteins were studied in miners working under conditions of the combine (the control group) and drilling-and-blasting (the contact with carbon oxide, nitrogen oxides) driving technique under normal temperature conditions. 26 to 27 protein fractions characterized by mobility, thermolability under definite conditions of the experiment and the contitative content were obtained. It is shown that the contact with carbon oxide and nitrogen oxides causes changes in the properties of certain proteins (II3, globulins - 2 alpha 1, 3 alpha 1, 2 beta, 2 alpha 2, 5 alpha 2, 6 alpha 2, 7 alpha 2) of miners' blood serum. Some of these proteins are supposed to participate in the adaptation reactions of the organism.

    Full Text Available ObjectiveDifferent studies have demonstrated that regular exercise can induce changes in the lipid profile, but results remain inconclusive. Available data suggest that correction of vitamin D deficiency can improve the lipid profile. In this study, we have hypothesized that Nordic Walking training will improve lipid profile in elderly women supplemented with vitamin D.MethodsA total of 109 elderly women (68 ± 5.12 years old took part in the study. First group [experimental group (EG: 35 women] underwent 12 weeks of Nordic Walking (NW training combined with vitamin D supplementation (4,000 IU/day, second group [supplementation group (SG: 48 women] was only supplemented with vitamin D (4,000 IU/day, and third group [control group (CG: 31 women] was not subject to any interventions. Blood analysis of total cholesterol (TC, triglycerides (TG, high-density lipoprotein cholesterol (HDL-C, low-density lipoprotein cholesterol (LDL-C, and 25-OH-D3 was performed at baseline and after the 12 weeks of NW training. Additionally, a battery of field tests specifically developed for older adults was used to assess the components of functional fitness. The same blood analysis was repeated for the EG 6 months after the main experiment.ResultsAfter 12 weeks of NW training and vitamin D supplementation, in the EG a decrease in TC, LDL-C, and TG was observed. In the SG, no changes in the lipid profile were observed, whereas in the CG an increase in the HDL-C level was noticed. Positive physical fitness changes were only observed in the EG.ConclusionOur obtained data confirmed baseline assumption that regular exercise induces positive alternations in lipid profile in elderly women supported by supplementation of vitamin D.

    To determine serum neopterin levels in blood donors of local population and its association with transfusion ransmitted infections. Study Design: A cross-sectional observational study. Place and Duration of Study:Department of Physiology, Liaquat National Hospital and Medical College (LNHMC) in collaboration with Basic Medical Sciences Institute (BMSI) and Jinnah Postgraduate Medical Centre (JPMC), Blood Bank, Karachi, Pakistan, from January to June 2015. Methodology: During this period, a total of 174 blood donors were selected through random sampling technique. All participants fulfilling the inclusion criteria involving apparently healthy blood donors of either gender within the age bracket of 18 - 60 years and consenting to participate were selected. The participants were screened for transfusion transmitted infections as per WHO recommendations through the standard procedures used for screening at the JPMC blood bank. The demographic profile, anthropometric measurements and vitals were recorded for every participant. Serum neopterin was measured using ELISA kits. Data was analysed on SPSS version 21. ANOVA and chi-square tests were applied as tests of significance at a p-value of <0.05. Results: The neopterin content in the sera of disease negative blood donors was 6.23 +-2.19 nmol/l as compared to disease positive blood donors, in whom the neopterin level was increased to 15.10 +-4.93 nmol/l (p =0.001). Conclusion: The neopterin assay has the potential to detect a number of transfusion transmissible viral diseases; which may, or may not be revealed by the usually employed battery of routine tests. We conclude that the risk of transfusion transmitted pathogens in our population can be reduced significantly, using neopterin assay as a routine in blood banks. (author)

  4. Anthocyanin-Rich Juice Lowers Serum Cholesterol, Leptin, and Resistin and Improves Plasma Fatty Acid Composition in Fischer Rats.

    Directory of Open Access Journals (Sweden)

    Daniela Graf

    Full Text Available Obesity and obesity-associated diseases e.g. cardiovascular diseases and type 2 diabetes are spread worldwide. Anthocyanins are supposed to have health-promoting properties, although convincing evidence is lacking. The aim of the present study was to investigate the effect of anthocyanins on several risk factors for obesity-associated diseases. Therefore, Fischer rats were fed anthocyanin-rich grape-bilberry juice or an anthocyanin-depleted control juice for 10 weeks. Intervention with anthocyanin-rich grape-bilberry juice reduced serum cholesterol and tended to decrease serum triglycerides. No effects were seen for serum non-esterified fatty acids, glucose, and insulin. Anthocyanin-rich grape-bilberry juice intervention reduced serum leptin and resistin, but showed no influence on serum adiponectin and secretion of adipokines from mesenteric adipose tissue. Furthermore, anthocyanin-rich grape-bilberry juice increased the proportion of polyunsaturated fatty acids and decreased the amount of saturated fatty acids in plasma. These results indicate that anthocyanins possess a preventive potential for obesity-associated diseases.

    To assess the dietary determinants of serum total cholesterol. Cross-sectional population-based study. Peri-urban region of Dar es Salaam, Tanzania. 347 adults aged 40 years and older from the Dar es Salaam Urban Cohort Hypertension Study. Serum total cholesterol measured using a point-of-care device. Mean serum total cholesterol level was 204 mg/dL (IQR 169-236 mg/dL) in women and 185 mg/dL (IQR 152-216 mg/dL) in men. After adjusting for demographic, socioeconomic, lifestyle and dietary factors, participants who reported using palm oil as the major cooking oil had serum total cholesterol higher by 15 mg/dL (95% CI 1 to 29 mg/dL) compared with those who reported using sunflower oil. Consumption of one or more servings of meat per day (p for trend=0.017) and less than five servings of fruits and vegetables per day (p for trend=0.024) were also associated with higher serum total cholesterol. A combination of using palm oil for cooking, eating more than one serving of meat per day and fewer than five servings of fruits and vegetables per day, was associated with 46 mg/dL (95% CI 16 to 76 mg/dL) higher serum total cholesterol. Using palm oil for cooking was associated with higher serum total cholesterol levels in this peri-urban population in Dar es Salaam. Reduction of saturated fat content of edible oil may be considered as a population-based strategy for primary prevention of cardiovascular diseases. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2017.

  6. Effects of blood collection conditions on ovarian cancer serum markers.

    Full Text Available Evaluating diagnostic and early detection biomarkers requires comparing serum protein concentrations among biosamples ascertained from subjects with and without cancer. Efforts are generally made to standardize blood processing and storage conditions for cases and controls, but blood sample collection conditions cannot be completely controlled. For example, blood samples from cases are often obtained from persons aware of their diagnoses, and collected after fasting or in surgery, whereas blood samples from some controls may be obtained in different conditions, such as a clinic visit. By measuring the effects of differences in collection conditions on three different markers, we investigated the potential of these effects to bias validation studies.We analyzed serum concentrations of three previously studied putative ovarian cancer serum biomarkers-CA 125, Prolactin and MIF-in healthy women, women with ovarian cancer undergoing gynecologic surgery, women undergoing surgery for benign ovary pathology, and women undergoing surgery with pathologically normal ovaries. For women undergoing surgery, a blood sample was collected either in the clinic 1 to 39 days prior to surgery, or on the day of surgery after anesthesia was administered but prior to the surgical procedure, or both. We found that one marker, prolactin, was dramatically affected by collection conditions, while CA 125 and MIF were unaffected. Prolactin levels were not different between case and control groups after accounting for the conditions of sample collection, suggesting that sample ascertainment could explain some or all of the previously reported results about its potential as a biomarker for ovarian cancer.Biomarker validation studies should use standardized collection conditions, use multiple control groups, and/or collect samples from cases prior to influence of diagnosis whenever feasible to detect and correct for potential biases associated with sample collection.

    Although it is known that polychlorinated biphenyls (PCBs) have adverse impacts on human health, it is not clear if human health impacts are caused by the PCBs or their related hydroxylated (OH) PCB metabolite compounds. This study measured OH-PCB metabolites in the maternal blood serum specimens from the Svidnik and Michalovce areas in eastern Slovakia where PCBs were intensively produced and inadequately disposed. The aim of the study was to characterize and quantify levels of specific OH-PCB metabolites in Slovakian maternal serums exposed to high environmental PCB levels. All specimens were analyzed for PCBs, and a subset of the samples was analyzed for OH-PCB metabolites. The Wallenburg blood extraction method was adopted to separate the OH-PCBs from the blood serums. Final eluates and calibration standards were spiked with PCB209 as an injection standard before gas chromatography (GC) analysis. OH-PCBs in the samples range from 75{+-}9 per cent to 101{+-}11 per cent. Median concentrations of OH-PCB metabolites of Michalovce samples were approximately twice as high as for the Svidnik samples. Concentrations of OH-PCBs of Michalovce blood samples were comparable to samples obtained from northern Canadian female Inuit and Faroe Island females, and were considered to be among the highest OH-PCB concentrations obtained in human blood. It was concluded that further research is needed to understand the placental transfer of OH-PCBs to the fetus, as well as epidemiological approaches to determine the relationship between the exposure of OH-PCB metabolites and child development. 12 refs., 2 figs.

    To measure the content of cholesterol-raising diterpenes in coffee sold at the retailer level in Singapore, Indonesia and India and to determine the relationship of coffee consumption with lipid levels in a population-based study in Singapore. Survey and cross-sectional study in local coffee shops in Singapore, Indonesia and India to measure the diterpene content in coffee, and a population-based study in Singapore to examine the relationship of coffee consumption and blood lipid levels. Interviews and coffee samples (n=27) were collected from coffee shops in Singapore, Indonesia and India. In addition, 3000 men and women who were Chinese, Malay, and Indian residents of Singapore participated in a cross-sectional study. The traditional 'sock' method of coffee preparation used in Singapore resulted in cafestol concentrations comparable to European paper drip filtered coffee (mean 0.09±SD 0.064 mg/cup). This amount would result in negligible predicted increases in serum cholesterol and triglyceride concentrations. Similarly low amounts of cafestol were found in Indian 'filter' coffee that used a metal mesh filter (0.05±0.05 mg/cup). Coffee samples from Indonesia using the 'sock' method (0.85±0.41 mg/cup) or a metal mesh filter (0.98 mg/cup) contained higher amounts of cafestol comparable to espresso coffee. Unfiltered coffee from Indonesia contained an amount of cafestol (4.43 mg/cup) similar to Scandinavian boiled, Turkish and French press coffee with substantial predicted increases in serum cholesterol (0.33 mmol/l) and triglycerides (0.20 mmol/l) concentrations for consumption of 5 cups per day. In the Singaporean population, higher coffee consumption was not substantially associated with serum lipid concentrations after adjustment for potential confounders [LDL-cholesterol: 3.07 (95% confidence interval 2.97-3.18) for Singapore and India, coffee consumption in these countries does not appear to be a risk factor for elevation of serum cholesterol, whereas

    The objective of this study was to describe serum lipid concentrations, including apolipoproteins A-I and B, in different diet groups. A cross-sectional analysis of a sample of 424 meat-eaters, 425 fish-eaters, 423 vegetarians and 422 vegans, matched on sex and age, from the European Prospective Investigation into Cancer and Nutrition-Oxford cohort. Serum concentrations of total, and high-density lipoprotein (HDL) cholesterol, as well as apolipoproteins A-I and B were measured, and serum non-HDL cholesterol was calculated. Vegans had the lowest body mass index (BMI) and the highest and lowest intakes of polyunsaturated and saturated fat, respectively. After adjustment for age, alcohol and physical activity, compared with meat-eaters, fish-eaters and vegetarians, serum concentrations of total and non-HDL cholesterol and apolipoprotein B were significantly lower in vegans. Serum apolipoprotein A-I concentrations did not differ between the diet groups. In males, the mean serum total cholesterol concentration was 0.87 mmol/l lower in vegans than in meat-eaters; after further adjustment for BMI this difference was 0.76 mmol/l. In females, the difference in total cholesterol between these two groups was 0.6 mmol/l, and after further adjustment for BMI was 0.55 mmol/l. [corrected]. In this study, which included a large number of vegans, serum total cholesterol and apolipoprotein B concentrations were lower in vegans compared with meat-eaters, fish-eaters and vegetarians. A small proportion of the observed differences in serum lipid concentrations was explained by differences in BMI, but a large proportion is most likely due to diet.

    Probiotic bacteria have been associated with a reduction in cardiovascular disease risk, a leading cause of death and disability. The aim of this study was to assess the impact of dietary administration of exopolysaccharide-producing probiotic Lactobacillus cultures on lipid metabolism and gut microbiota in apolipoprotein E (apoE)-deficient mice. First, we examined lipid metabolism in response to dietary supplementation with recombinant β-glucan-producing Lactobacillus paracasei National Food Biotechnology Centre (NFBC) 338 expressing the glycosyltransferase (Gtf) gene from Pediococcus parvulus 2.6 (GTF), and naturally exopolysaccharide-producing Lactobacillus mucosae Dairy Product Culture Collection (DPC) 6426 (DPC 6426) compared with the non-β-glucan-producing isogenic control strain Lactobacillus paracasei NFBC 338 (PNZ) and placebo (15% wt:vol trehalose). Second, we examined the effects on the gut microbiota of dietary administration of DPC 6426 compared with placebo. Probiotic Lactobacillus strains at 1 × 10(9) colony-forming units/d per animal were administered to apoE(-/-) mice fed a high-fat (60% fat)/high-cholesterol (2% wt:wt) diet for 12 wk. At the end of the study, aortic plaque development and serum, liver, and fecal variables involved in lipid metabolism were analyzed, and culture-independent microbial analyses of cecal content were performed. Total cholesterol was reduced in serum (P mice supplemented with GTF or DPC 6426 compared with the PNZ or placebo group, respectively. In addition, dietary intervention with GTF led to increased amounts of fecal cholesterol excretion (P mice. © 2014 American Society for Nutrition.

    To explore relationship and significance of Serum Leptin with BMI, Insulin, triglyceride (TG) and total cholesterol (TC) in obese children aged 6-13 years. Serum Leptin of school-age children 118 (64 male, 54 female; normal non-obese 56 and obese 62) were deter- mined and compared with BMI, Insulin, TG and TC. The results showed that: (1) Each index of obese children was remarkably higher than that of non-obese children (P 0.05). (3) Leptin was poritinely corelation with BMI, insulin, TG and TC(P=0.001). Leptin level in serum may varied according to sex, BMI or blood lipid level. It is of great significance in prevention and treatment of obesity to use drug which may improve Leptin receptor effect.

    Retinal pigment epithelium (RPE) has been implicated as key source of cholesterol-rich deposits at Bruch's membrane (BrM) and in drusen in aging human eye. We have shown that serum-deprivation of confluent RPE cells is associated with upregulation of cholesterol synthesis and accumulation of unesterified cholesterol (UC). Here we investigate the cellular processes involved in this response. We compared the distribution and localization of UC and esterified cholesterol (EC); the age-related macular degeneration (AMD) associated EFEMP1/Fibulin3 (Fib3); and levels of acyl-coenzyme A (CoA): cholesterol acyltransferases (ACAT) ACAT1, ACAT2 and Apolipoprotein B (ApoB) in ARPE-19 cells cultured in serum-supplemented and serum-free media. The results were compared with distributions of these lipids and proteins in human donor eyes with AMD. Serum deprivation of ARPE-19 was associated with increased formation of FM dye-positive membrane vesicles, many of which co-labeled for UC. Additionally, UC colocalized with Fib3 in distinct granules. By day 5, serum-deprived cells grown on transwells secreted Fib3 basally into the matrix. While mRNA and protein levels of ACTA1 were constant over several days of serum-deprivation, ACAT2 levels increased significantly after serum-deprivation, suggesting increased formation of EC. The lower levels of intracellular EC observed under serum-deprivation were associated with increased formation and secretion of ApoB. The responses to serum-deprivation in RPE-derived cells: accumulation and secretion of lipids, lipoproteins, and Fib3 are very similar to patterns seen in human donor eyes with AMD and suggest that this model mimics processes relevant to disease progression.

    Hormones or metabolites which are capable of producing antibodies can be detected and precisely quantitated by this method. Antibodies, to various hormones or metabolites whose assay is desired, are adsorbed onto commercially available imitation or cultured pearls. These pearls coated with antibody are contacted with a buffered reaction mixture containing blood serum or plasma specimen and respective radioactive antigen. The entire reaction is allowed to proceed for a time sufficient to form antigen (radioactive or non-radioactive)-antibody complex. These complexes on the pearls are washed and the total amount of radioactivity emanating from the complex is measured. This is indicative of the extent of binding of radioactive antigen and provides an indirect correlation of the amount of non-radioactive antigen present in the serum or plasma sample

    Full Text Available Context: Gender differences in the risk of developing non-communicable diseases (NCD are a matter of debate. The susceptibility of a woman to NCD should be evaluated taking into consideration the social factors that limit the physical activity among women. It will be interesting to note what will happen if women are allowed to take part in physical exercise to the extent of men. Aims: To find out the gender difference in the pattern of the clinical and biochemical indices related to NCD in young adults with comparable daily physical activity. Settings and Design: This is an institution-based cross-sectional study and the setting was Lekshmibhai National College for Physical Education (LNCPE, Thiruvananthapuram, Kerala, India. Materials and Methods: The study participants were students who were regularly involved in more than three hours of physical exercise daily at least for the previous one year. The information on socio-demography, anthropometry, and blood pressure was recorded. Blood samples were taken for laboratory examination. Results: Out of 150 students registered, 126 (84% in the age group of 17 to 25 years who fulfilled the eligibility criteria were studied. Fifty-five (43.7% of them were women. Systolic blood pressure, fasting blood sugar, and low-density lipoprotein were found significantly lower in women. No significant difference was noted in the case of diastolic blood pressure and total cholesterol. Conclusion: Gender differences exist for NCD risk factors among young adults with comparable physical activity and physical exertion seems to be more protective for females.

    The present study aims to consider the effect of 10 weeks resistance trainings on cholesterol and blood triglyceride (TG) levels of patients with having fatty liver, aged 50 to 60 in National Iranian South Oil Company (NISOC). This research is practical and its plan has been done experimentally with pretest and post-test on experimental and control groups. In this study, 20 samples from 100 patients who referred to sonography clinic in NISOC with distinction of fatty liver were selected randomly and divided into two groups of control (n = 10) and experimental (n = 10). Cholesterol and blood trigly-ceride were measured as pretest. Test of normality for TG was (p = 0/200) by Kolmogorov-Smirnov and (p = 0/070) for cholesterol by Shapiro-Wilk test. After 10 weeks resistance trainings, the analysis and resolution of data were done by computer and SPSS (16) software as well as the descriptive and statistical methods (t-test). Comparison between these two groups showed that 8 weeks resistance trainings with a ≤ 0.05 causes significant decrease in the amount of TG but did not any significant effect on cholesterol of fatty liver patients.

    Full Text Available OBJECTIVE: Childhood and adolescent overweight, defined by body mass index (BMI are associated with an increased risk of cardiovascular disease in later life. Abdominal adiposity may be more important in associations with cardiovascular diseases but waist circumference (WC has been rarely studied in children. We studied associations between BMI and WC and blood pressure (BP and cholesterol in 12-year-old children and prospectively changes in BMI or WC status between age 8 and 12 years and BP and cholesterol at age 12. STUDY DESIGN: Weight, height, WC, BP and cholesterol concentrations were measured in 1432 children at age 12 years. Linear regression was used to study the associations between high BMI and large WC (>90(th percentile and BP and cholesterol. RESULTS: Systolic BP was 4.9 mmHg higher (95% (CI 2.5, 7.2 in girls and 4.2 mmHg (95%CI 1.9, 6.5 in boys with a high BMI. Large WC was also associated with higher systolic BP in girls (3.7 mmHg (95%CI 1.3, 6.1 and boys (3.5 mmHg (95%CI 1.2, 5.8. Diastolic BP and cholesterol concentrations were significantly positively (HDL cholesterol negatively associated with high BMI and large WC, too. Normal weight children with a history of overweight did not have higher blood pressure levels or adverse cholesterol concentrations than children that were normal weight at both ages. CONCLUSION: A high BMI and large WC were associated with higher BP levels and adverse cholesterol concentrations. WC should be taken into account when examining cardiovascular risk factors in children.

    Full Text Available In order to investigate the effect of different levels of the additive containing Artichoke premix concentrated (APC on growth performance, serum cholesterol level, carcass characteristics and immune responses of broilers two separate trials were conducted. In the first trial, APC was added at three levels of 0, 100 and 200 gr/ton diet during the first 21 days of growing period. One hundred and fifty unsexed day old broiler chickens of Ross strain were randomly divided in three groups with 5 replicate of 10 chicks in each cage, by a completely randomized design. At the end of each week, the birds were weighed individually and feed conversion ratios calculated. In order to determine serum cholesterol level, at day 21 blood sample was taken from 15 chickens per treatment. At the end of the 42nd day, 5 birds from each group were randomly selected and slaughtered for investigation of carcass characteristics. In the second trial, the effects of APC at 150gr/ton feed were studied on growth parameters and immune function of broiler chickens in a commercial farm. The results showed that application of APC in a level of 200 gr/ton diet significantly increased body weight of chickens at the first (p

    Full Text Available Abstract Background Genes implicated in common complex disorders such as obesity, type 2 diabetes mellitus (T2DM or cardiovascular diseases are not disease specific, since clinically related disorders also share genetic components. Cysteine protease Calpain 10 (CAPN10 has been associated with T2DM, hypertension, hypercholesterolemia, increased body mass index (BMI and polycystic ovary syndrome (PCOS, a reproductive disorder of women in which isunlin resistance seems to play a pathogenic role. The calpain 5 gene (CAPN5 encodes a protein homologue of CAPN10. CAPN5 has been previously associated with PCOS by our group. In this new study, we have analysed the association of four CAPN5 gene variants(rs948976A>G, rs4945140G>A, rs2233546C>T and rs2233549G>A with several cardiovascular risk factors related to metabolic syndrome in general population. Methods Anthropometric measurements, blood pressure, insulin, glucose and lipid profiles were determined in 606 individuals randomly chosen from a cross-sectional population-based epidemiological survey in the province of Segovia in Central Spain (Castille, recruited to investigate the prevalence of anthropometric and physiological parameters related to obesity and other components of the metabolic syndrome. Genotypes at the four polymorphic loci in CAPN5 gene were detected by polymerase chain reaction (PCR. Results Genotype association analysis was significant for BMI (p ≤ 0.041, diastolic blood pressure (p = 0.015 and HDL-cholesterol levels (p = 0.025. Different CAPN5 haplotypes were also associated with diastolic blood pressure (DBP (0.0005 ≤ p ≤ 0.006 and total cholesterol levels (0.001 ≤ p ≤ 0.029. In addition, the AACA haplotype, over-represented in obese individuals, is also more frequent in individuals with metabolic syndrome defined by ATPIII criteria (p = 0.029. Conclusion As its homologue CAPN10, CAPN5 seems to influence traits related to increased risk for cardiovascular diseases. Our

    Full Text Available Background: The fatty acid (FA composition of serum lipids is related to the quality of dietary fat intake. Objective: To investigate the effects of a healthy Nordic diet (ND on the FA composition of serum cholesterol esters (CE-FA and assess the associations between changes in the serum CE-FA composition and blood lipoproteins during a controlled dietary intervention. Design: The NORDIET trial was a 6-week randomised, controlled, parallel-group dietary intervention study that included 86 adults (53±8 years with elevated low-density lipoprotein cholesterol (LDL-C. Serum CE-FA composition was measured using gas chromatography. Diet history interviews were conducted, and daily intake was assessed using checklists. Results: Food and nutrient intake data indicated that there was a reduction in the intake of fat from dairy and meat products and an increase in the consumption of fatty fish with the ND. The levels of saturated fatty acids in cholesterol esters (CE-SFA 14:0, 15:0, and 18:0, but not 16:0, showed a significant decrease after intake of ND compared to the control diet (p<0.01. Also, a significant increase in serum 22:6n – 3 was observed compared with the control diet (p<0.01. The changes in CE-SFA 14:0, 15:0, and 18:0 correlated positively with changes in LDL-C, HDL-C, LDL-C/HDL-C, ApoA1, and ApoB (p<0.01, respectively, whereas the changes in polyunsaturated fatty acids in cholesterol esters (CE-PUFA 22:6n – 3 were negatively correlated with changes in the corresponding serum lipids. Conclusions: The decreased intake of saturated fat and increased intake of n-3 PUFA in a healthy ND is partly reflected by changes in the serum CE-FA composition, which are associated with an improved serum lipoprotein pattern.

    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.

We have investigated the effect of theobromine (TB consumption on the concentrations of triglyceride (TG and cholesterol (CH in various lipoprotein (LP subclasses.Methods: In a randomized, double-blind, placebo-controlled, cross-over study, 44 apparently healthy women and men (age: 60 ± 6 years, BMI: 29 ± 3 kg/m2 with low baseline HDL-CH concentrations consumed a drink supplemented with 500 mg/d theobromine for 4 weeks. TG and CH concentrations in 15 LP subclasses were predicted from diffusion-edited 1H NMR spectra of fasting serum.Results: The LP phenotype of the subjects was characterized by low CH concentrations in the large HDL particles and high TG concentrations in large VLDL and chylomicron (CM particles, which clearly differed from a LP phenotype of subjects with normal HDL-CH. TB only reduced CH concentrations in the LDL particles by 3.64 and 6.79%, but had no effect on TG and CH in any of the HDL, VLDL and CM subclasses.Conclusion: TB was not effective on HDL-CH in subjects with a LP phenotype characterized by low HDL-CH and high TG in VLDL.

    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. Highlights: Black-Right-Pointing-Pointer A novel biosensor was developed to determine glucose and cholesterol simultaneously. Black-Right-Pointing-Pointer The dual enzymatic-biosensor has good selectivity and high sensitivity. Black-Right-Pointing-Pointer We determined glucose and cholesterol in the real samples of diabetic mice.

These findings indicated the possibility that high glucose induced by diabetes might increase the macrophage cholesterol level to further accelerate atherosclerosis development. Highlights: ► A novel biosensor was developed to determine glucose and cholesterol simultaneously. ► The dual enzymatic-biosensor has good selectivity and high sensitivity. ► We determined glucose and cholesterol in the real samples of diabetic mice. ► The results showed that high glucose might increase the macrophage cholesterol level. ► It provided useful experimental evidences for diabetes-accelerate atherosclerosis. - Abstract: In this paper, a novel dual enzymatic-biosensor is described for

    1991-01-01

    A simple, fast and reliable liquid chromatographic method for the determination of theophylline in serum and capillary blood after a solid phase extraction is described for therapeutic drug monitoring. The employment of capillary blood permits the determination of an individual drug profile and other pharmacokinetic studies in neonates and infants. There were no differences in venous- and capillary-blood levels but these values compared poorly with those in serum. An adjustment of the results by correction of the different volumes of serum and blood by haematocrit was unsuccessful. Differences in the binding of theophylline to erythrocytes could be an explanation for the differences in serum at blood levels of theophylline.

    In patients with chronic heart failure (CHF) increasing levels of total serum cholesterol are associated with improved survival - while statin usage is not. The impact of statin treatment on the "reverse epidemiology" of cholesterol is unclear. 2992 consecutive patients with non-ischemic CHF due to left ventricular systolic dysfunction from the Norwegian CHF Registry and the CHF Registries of the Universities of Hull, UK, and Heidelberg, Germany, were studied. 1736 patients were individually double-matched on both cholesterol levels and the individual propensity scores for statin treatment. All-cause mortality was analyzed as a function of baseline cholesterol and statin use in both the general and the matched sample. 1209 patients (40.4%) received a statin. During a follow-up of 13,740 patient-years, 360 statin users (29.8%) and 573 (32.1%) statin non-users died. When grouped according to total cholesterol levels as low (≤3.6mmol/L), moderate (3.7-4.9mmol/L), high (4.8-6.2mmol/L), and very high (>6.2mmol/L), we found improved survival with very high as compared with low cholesterol levels. This association was present in statin users and non-users in both the general and matched sample (p<0.05 for each group comparison). The negative association of total cholesterol and mortality persisted when cholesterol was treated as a continuous variable (HR 0.83, 95%CI 0.77-0.90, p<0.001 for matched patients), but it was less pronounced in statin users than in non-users (F-test p<0.001). Statins attenuate but do not eliminate the reverse epidemiological association between increasing total serum cholesterol and improved survival in patients with non-ischemic CHF.

  13. Effect of a multivitamin preparation supplemented with phytosterol on serum lipids and infarct size in rats fed with normal and high cholesterol diet

    Science.gov (United States)

    2013-01-01

    Background Although complex multivitamin products are widely used as dietary supplements to maintain health or as special medical food in certain diseases, the effects of these products were not investigated in hyperlipidemia which is a major risk factor for cardiovascular diseases. Therefore, here we investigated if a preparation developed for human use containing different vitamins, minerals and trace elements enriched with phytosterol (VMTP) affects the severity of experimental hyperlipidemia as well as myocardial ischemia/reperfusion injury. Methods Male Wistar rats were fed a normal or cholesterol-enriched (2% cholesterol + 0.25% cholate) diet for 12 weeks to induce hyperlipidemia. From week 8, rats in both groups were fed with a VMTP preparation or placebo for 4 weeks. Serum triglyceride and cholesterol levels were measured at week 0, 8 and 12. At week 12, hearts were isolated, perfused according to Langendorff and subjected to a 30-min coronary occlusion followed by 120 min reperfusion to measure infarct size. Results At week 8, cholesterol-fed rats showed significantly higher serum cholesterol level as compared to normal animals, however, serum triglyceride level did not change. VMTP treatment significantly decreased serum cholesterol level in the hyperlipidemic group by week 12 without affecting triglyceride levels. However, VMTP did not show beneficial effect on infarct size. The inflammatory marker hs-CRP and the antioxidant uric acid were also not significantly different. Conclusions This is the first demonstration that treatment of hyperlipidemic subjects with a VMTP preparation reduces serum cholesterol, the major risk factor for cardiovascular disease; however, it does not provide cardioprotection.

    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.

    An objective of this study is to search how physical examination and diet consultation can influence those risk factors of cardiovascular disease. The subjects were 326 pilots of the "B" airline company in Korea whose total cholesterol values were over 220 mg/dl on their regular physical examinations from April 2006 to December 2008. They were divided into two groups, one who had diet consultation (an intervention group) and a control group. The physical examination components used to each group were body mass index (BMI), total cholesterol (TC), high density lipoprotein (HDL), low density lipoprotein (LDL) and triglyceride (TG). The behavioral, anthropometric and biomedical measurements were collected at each visit. This study compares and investigates the changes of serum cholesterol and also the health-behavior at each physical examination. Within the intervention group significant improvements were observed for total cholesterol, BMI (body mass index) and HDL (high density lipoprotein). The normalizing rates for cholesterol level to decrease down to lower than 200 mg/dl were 17.7% in intervention group and 8.7% in control group, which is statistically significantly higher among the intervention group. The odds ratio of diet consultation was 2.80 (95% CI=1.35-5.79), which indicates that it is a significantly contributing factor to normalize the serum cholesterol value down to lower than 200 mg/dl. Based on result, it is recommended to have regular physical examination and intensive management with diet and exercise consultation.

    Full Text Available Abstract Background Fucoxanthin is a xanthophyll present in brown seaweeds and has several beneficial effects, including anti-obesity and anti-diabetic effects. However, we and another group previously observed that fucoxanthin increases serum cholesterol levels in rodents. Cholesterol is an important component of cell membranes and biosynthesis of bile acids. Serum cholesterol levels are also closely associated with atherosclerosis. Therefore, we sought to identify the mechanism underlying the increase in serum cholesterol levels by fucoxanthin. Methods Diabetic/obese KK-Ay mice were fed a diet containing 0.2% fucoxanthin for 4 weeks. The mice were sacrificed, and total blood samples were collected for the measurement of serum total cholesterol, HDL-cholesterol and non-HDL-cholesterol levels. Cholesterol content in tissues was also analyzed. Real-time PCR and Western blotting were performed to determine hepatic mRNA and protein expression of genes involved in cholesterol metabolism, respectively. Results Dietary fucoxanthin significantly increased serum HDL and non-HDL cholesterol levels, and reduced hepatic cholesterol content. In liver, the expression of SREBP1, SREBP2 and their target genes involved in cholesterol biosynthesis significantly increased and tended to increase in the fucoxanthin-fed mice, respectively. In contrast, hepatic levels of LDLR and SR-B1 proteins which is important factors for LDL-cholesterol and HDL-cholesterol uptake in the liver from serum, decreased to 60% and 80% in the fucoxanthin-fed mice, respectively, compared with the control mice. Further, we found that dietary fucoxanthin significantly increased the mRNA expression of proprotein convertase subtilisin/kexin type 9 (PCSK9, which enhances intracellular degradation of LDLR in lysosomes. Conclusions Fucoxanthin increased HDL-cholesterol and non-HDL-cholesterol levels in KK-Ay mice by inducing SREBP expression and reduced cholesterol uptake in the liver via

    The effects were compared of the addition of graded levels of L-cystine and of L-cysteine (0.3, 3, or 5%) to a 10% casein diet on several metabolic parameters in rats. The growth-promoting effect of cystine was equivalent to that of cysteine. Supplementation of these two amino acids elevated serum cholesterol, liver ascorbic acid, liver nonprotein sulfhydryl (SH) and kidney metallothionein, and reduced the activity of serum ceruloplasmin. The responses of serum cholesterol, liver nonprotein SH, and serum ceruloplasmin to cystine were greater than of those to cysteine. When the basal diet was supplemented with 0.3% of these amino acids, the elevation of liver ascorbic acid by cystine supplementation was less than that by cysteine supplementation. However, when supplemented with 5% of these amino acids, the elevation of liver ascorbic acid by cystine was greater than that by cysteine. There was no difference in the influence of cystine and cysteine on kidney metallothionein. This study demonstrates that dietary cystine and cysteine had the same influence on growth, but had a differential influence on such metabolic parameters as liver nonprotein SH, serum ceruloplasmin, serum cholesterol, and tissue ascorbic acid.

    Full Text Available   Abstract INTRODUCTION: Dyslipidemia is one of the major risk factors of cardiovascular disease. Nutrition can significantly affect blood lipids. Eggs are a common food for many people and are rich in nutrients and vitamins. They are also rich in cholesterol. Considering the different recommendations and controversies surrounding the healthiness or otherwise of egg consumption, we added two eggs to the usual daily dietary regimen of healthy normolipidemic young volunteers and monitored the changes in their lipid profile. methods: This clinical trial was done on 60 volunteers living in a university campus. They regularly ate food served in the university restaurant. Their diet was monitored from 2 weeks before the start of the new diet with additional eggs. Fasting blood samples were taken at the beginning of the study. Two well-cooked moderately-sized eggs (all from the same supplier were added to the subjects' breakfast for one month. Blood lipids were measured again at the end of this period. results: Mean levels of total cholesterol, low-density lipoprotein cholesterol (LDL-C and triglyceride increased significantly, but remained within normal limits (P=0.001, 0.000 and 0.01, respectively. High-density lipoprotein cholesterol (HDL-C deceased significantly (P=0.000. CONCLUSIONS: Adding 14 eggs a week to the usual diet of normolipidemic healthy individuals can unfavorably affect blood lipids and may have adverse long-term cardiovascular consequences. In other words, eating less than two eggs a day may be a healthier practice.     Keywords: Egg, cholesterol, cardiovascular disease.

    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.

    The use of low level laser for body contouring and weight reduction depends on the photochemical non thermal effect of laser light on the adipose tissue. LLLT was reported to liquefy or release stored fat in adipocytes by the opening of specialized yet not identified cell membrane-associated pores after a brief treatment The concentration of leptin in adipose tissue and serum closely parallel the mass of adipose tissue and adipocyte size and triglycerides content. Thus, leptin increases in obesity and falls with weight loss. The current study was conducted to evaluate the effect of the low level laser therapy (LLLT) on leptin hormone, Cholesterol and triglyceride in both overweight and obese females. Twenty women were included in this study. Their ages ranged from 30-40 years. They were divided into two equal groups. Group A (Overweight group): included 10 females with BMI between 25 and 29.9 Kg/m2 -Group B (Obese group): included 10 females with BMI . 30. Both groups received LLL to the abdomen using laser scanner for uniform distribution of the beam above and below the umbilicus. Duration of treatment was 30 minutes, 2 times per week for 8 weeks as a total period of treatment. Serum level of leptin was estimated by radioimmunoassay (RIA). As regards serum cholesterol and triglyceride they were determined by enzymatic colorimetric test. Biochemical assessments were done before and after treatment. Results of the present study showed that in the overweight group laser treatment resulted in highly significant reduction in leptin serum level accompanied by highly significant increase in serum triglycerides level. Meanwhile, the increase in cholesterol level was insignificant. As regards the obese group, alteration in serum leptin level caused by laser treatment was not significant. In this group the increase in triglycerides and cholesterol serum levels after treatment were highly significant

    decreased, which conforms to changes of indicators in exchange of proteins. SGOT activity in the animals’ blood serum exceeded the upper rate of norm, it coincides also with rising of concentration of creatinine and sodium lactatum, and is an indicator of intensification of catabolic processes in the muscles after physical loading. Only after emotional loading, did hyperglycemia and hyperbilirubinemia occur because of a temporal spasm in the cholic paths without changes in the activity of the alkaline phosphatase and GGTP. After physical loading the level of lactatum increased (by 185.7%, activity of LDH (by 76.2%, concentration of cholesterol (by 76.2%, triacylglycerol (by 140.9%, which is an indicator of intensification of anaerobic glycolysis and lipolysis. Emotional loading is the stronger stress factor which causes negative changes in indicators of the metabolic profile. Trainers should take this into account during the training and testing of horses in order to facilitate their adaptation to the influence of various stress factors, to correct the animals’ physiological state and thus enable them to cope with intensive loading without threat to their health.

    Measuring and monitoring the true prevalence of risk factors for chronic conditions is essential for evidence-based policy and health service planning. Understanding the prevalence of risk factors for cardiovascular disease (CVD) in Australia relies heavily on self-report measures from surveys, such as the triennial National Health Survey. However, international evidence suggests that self-reported data may substantially underestimate actual risk factor prevalence. This study sought to characterise the extent of misreporting in a large, nationally-representative health survey that included objective measures of clinical risk factors for CVD. This study employed a cross-sectional analysis of 7269 adults aged 18 years and over who provided fasting blood samples as part of the 2011-12 Australian Health Survey. Self-reported prevalence of high blood pressure, high cholesterol and diabetes was compared to measured prevalence, and univariate and multivariate logistic regression analyses identified socio-demographic characteristics associated with underreporting for each risk factor. Approximately 16 % of the total sample underreported high blood pressure (measured to be at high risk but didn't report a diagnosis), 33 % underreported high cholesterol, and 1.3 % underreported diabetes. Among those measured to be at high risk, 68 % did not report a diagnosis for high blood pressure, nor did 89 % of people with high cholesterol and 29 % of people with high fasting plasma glucose. Younger age was associated with underreporting high blood pressure and high cholesterol, while lower area-level disadvantage and higher income were associated with underreporting diabetes. Underreporting has important implications for CVD risk factor surveillance, policy planning and decisions, and clinical best-practice guidelines. This analysis highlights concerns about the reach of primary prevention efforts in certain groups and implications for patients who may be unaware of their

    Full Text Available The developed method used three enzymes comprised of cholesterol esterase, cholesterol oxidase, and peroxidase for fabrication of amperometric biosensor in order to determine total cholesterol in serum samples. Gold nanoparticles (AuNPs and carboxylated multiwall carbon nanotubes (cMWCNTs were used to design core of working electrode, having covalently immobilized ChO, ChE, and HRP. Polyacrylamide layer was finally coated on working electrode in order to prevent enzyme leaching. Chemically synthesised Au nanoparticles were subjected to transmission electron microscopy (TEM for analysing the shape and size of the particles. Working electrode was subjected to FTIR and XRD. The combined action of AuNP and c-MWCNT showed enhancement in electrocatalytic activity at a very low potential of 0.27 V. The pH 7, temperature 40°C, and response time of 20 seconds, respectively, were observed. The biosensor shows a broad linear range from 0.5 mg/dL to 250 mg/dL (0.01 mM–5.83 mM with minimum detection limit being 0.5 mg/dL (0.01 mM. The biosensor showed reusability of more than 45 times and was stable for 60 days. The biosensor was successfully tested for determining total cholesterol in serum samples amperometrically with no significant interference by serum components.

    Previous research on male white rat with provision of Eurycoma longifolia until the 3rd days has increased significantly on the formation of final spermatid from spermatozoon, and testosterone, and increase activity of pituitary cell producing the LH hormone. However, these researches yet studied on possibility of side effects caused by provision of Eurycoma longifolia for 6 days on male EC goat. The research aims to measure the effect of Eurycoma longifolia on the levels of: 1). Blood sugar, 2). Cholesterols, and 3). Uric acid of Male Etawa Crossbreed (EC) goat. This research was conducted through two treatment groups, namely : 1). Control group (provision of aquadest) for 1 day, 3 days, and 6 days, 2) Eurycoma longifolia group with a dose of 90 mg/kg body weight (bb) for 1 day, 3 days, and 6 days. Measurements on the sugar blood, cholesterol and uric acid level were conducted in the 1st, 2nd and 6th days. The obtained data were analyzed using Duncan test with confidence level by 95% (α=0,05) comparing the sugar blood, cholesterol and uric acid measured from the control group in the 1st, 3rd and 6th days with the same compound level measured from the Eurycoma longifolia treatment group in the 1st, 3rd and 6th days. The result obtained there were no significant changes on the sugar blood, cholesterol and uric acid levels between all Eurycoma longifolia treatment groups compared to the control group in the 1st, 3rd and 6th days. Thus, the Eurycoma longifolia provision until in the 6th day did not provide any negative side effects and can be applied in the Etawa crossbreed goat farm.

    In spite of more than 100 years of investigations the question of whether a reduced sodium intake improves health is still unsolved. To estimate the effects of low sodium intake versus high sodium intake on systolic and diastolic blood pressure (SBP and DBP), plasma or serum levels of renin, aldosterone, catecholamines, cholesterol, high-density lipoprotein (HDL), low-density lipoprotein (LDL) and triglycerides. The Cochrane Hypertension Information Specialist searched the following databases for randomized controlled trials up to March 2016: the Cochrane Hypertension Specialised Register, the Cochrane Central Register of Controlled Trials (CENTRAL) (2016, Issue 3), MEDLINE (from 1946), Embase (from 1974), the World Health Organization International Clinical Trials Registry Platform, and ClinicalTrials.gov. We also searched the reference lists of relevant articles. Studies randomising persons to low-sodium and high-sodium diets were included if they evaluated at least one of the above outcome parameters. Two review authors independently collected data, which were analysed with Review Manager 5.3. A total of 185 studies were included. The average sodium intake was reduced from 201 mmol/day (corresponding to high usual level) to 66 mmol/day (corresponding to the recommended level).The effect of sodium reduction on blood pressure (BP) was as follows: white people with normotension: SBP: mean difference (MD) -1.09 mmHg (95% confidence interval (CI): -1.63 to -0.56; P = 0.0001); 89 studies, 8569 participants; DBP: + 0.03 mmHg (MD 95% CI: -0.37 to 0.43; P = 0.89); 90 studies, 8833 participants. High-quality evidence. Black people with normotension: SBP: MD -4.02 mmHg (95% CI:-7.37 to -0.68; P = 0.002); seven studies, 506 participants; DBP: MD -2.01 mmHg (95% CI:-4.37 to 0.35; P = 0.09); seven studies, 506 participants. Moderate-quality evidence. Asian people with normotension: SBP: MD -0.72 mmHg (95% CI: -3.86 to 2.41; P = 0.65); DBP: MD -1.63 mmHg (95% CI:-3.35 to 0

    Using data from the Third National Health and Nutrition Examination Survey (1988-1994), the authors examined the relation between periodontal health and cardiovascular risk factors: serum total and high density lipoprotein cholesterol, C-reactive protein, and plasma fibrinogen. A total of 10,146 participants were included in the analyses of cholesterol and C-reactive protein and 4,461 in the analyses of fibrinogen. Periodontal health indicators included the gingival bleeding index, calculus index, and periodontal disease status (defined by pocket depth and attachment loss). While cholesterol and fibrinogen were analyzed as continuous variables, C-reactive protein was dichotomized into two levels. The results show a significant relation between indicators of poor periodontal status and increased C-reactive protein and fibrinogen. The association between periodontal status and total cholesterol level is much weaker. No consistent association between periodontal status and high density lipoprotein cholesterol was detectable. Similar patterns of association were observed for participants aged 17-54 years and those 55 years and older. In conclusion, this study suggests that total cholesterol, C-reactive protein, and fibrinogen are possible intermediate factors that may link periodontal disease to elevated cardiovascular risk.

    The goal of the present study was to investigate whether subchronic treatment with grape juice concentrate is able to protect liver and peripheral blood cells against cholesterol-induced injury in rats. The effects of the grape juice concentrate treatment on histopathological changes, immunohistochemistry for cyclo-oxygenase-2 (COX-2), and basal and oxidative DNA damage induced by H2O2 using a single-cell gel (comet) assay were evaluated. Male Wistar rats (n 18) were divided into three groups: group 1--negative control; group 2--cholesterol at 1 % (w/w) in their diet, treated for 5 weeks; group 3--cholesterol at 1 % in their chow, treated for 5 weeks, and grape juice concentrate at 222 mg/d in their drinking-water in the final week only. The results indicated that the treatment with grape juice concentrate did not show remarkable differences regarding liver tissue in group 3 compared with group 2. However, grape juice concentrate was able to decrease oxidative DNA damage induced by H2O2 in peripheral blood cells, as depicted by the tail moment results. COX-2 expression in the liver did not show statistically significant differences (P>0·05) between groups. Taken together, the present results suggest that the administration of subchronic grape juice concentrate prevents oxidative DNA damage in peripheral blood cells.

    Selenium is an antioxidant that prevents oxygen radical from damaging cells from chronic diseases that can develop from cell injury and inflammation such as diabetes mellitus. The aim of the study is to investigate the possible protective effect of selenium yeast on cholesterol diet induced type-2 diabetes mellitus and oxidative stress in rats. Twenty male wistar rats were divided in to four groups of five animals each: Group 1: (Negative control) received standard animal feed only, Group 2:  received cholesterol diet (CD) only, Group 3: received CD and 0.1 mg/kg selenium yeast orally, Group 4: Received CD and 0.2 mg/kg selenium yeast orally for six weeks. At the end of the study period, the animals were sacrificed and the serum samples were collected and evaluated for estimation of antioxidant enzymes such as superoxide dismutase (SOD), catalase (CAT) and glutathione peroxidase (GPx). The results showed a significant decrease in blood glucose level in the groups  co-administered CD and selenium yeast when compared to CD group only. Antioxidant enzymes status recorded significant decrease in SOD, CAT and GPx activities in CD and selenium yeast administered when compared to CD group only. In Conclusion, Selenium yeast administrations prevent free radical formations which are potent inducer of diabetes mellitus.

    Women with prior preeclamptic pregnancies have an increased risk for metabolic syndrome and cardiovascular diseases. Maternal preeclampsia has been associated with elevated blood pressure (BP) in offspring during childhood. The aim of our study was to determine whether elevated BP pressure and metabolic changes, such as dyslipidemia, insulin resistance, and increased adrenal hormonal activity, are found in 12-yr-old children of preeclamptic mothers. Sixty children born after preeclamptic pregnancy (PRE) and 60 matched control subjects born after normotensive pregnancy (non-PRE) were studied at the age of 12 yr. The case-control pairs were matched for sex, gestational age (+/-1 wk), and size at birth. We measured BP and concentrations of blood glucose, serum fasting insulin, total and high density lipoprotein cholesterol, triglycerides, cortisol, dehydroepiandrosterone sulfate, and plasma epinephrine (E) and norepinephrine (NE). Low density lipoprotein cholesterol was calculated according to the Friedewald-Fredrickson formula. The PRE children had significantly higher mean systolic (116.4 vs. 113.2 mm Hg; P = 0.021) and diastolic (73.9 vs. 70.3 mm Hg; P = 0.022) BP than the non-PRE children, even when adjusted by current weight and height. At 12 yr of age, systolic BP values correlated inversely with birth weight (r = -0.459; P < 0.001) and length SD scores (r = -0.429; P = 0.001) in the PRE children. The mean concentrations of serum total, low density lipoprotein, and high density lipoprotein cholesterol; triglycerides; fasting insulin; blood glucose; serum cortisol; and dehydroepiandrosterone sulfate did not differ between the PRE and non-PRE groups. However, the mean plasma E concentration was higher in the PRE than in the non-PRE children (0.32 vs. 0.28 nmol/liter; P = 0.042), whereas the mean NE concentration did not differ between these two groups. In conclusion, 12-yr-old children born with maternal preeclampsia had elevated systolic and diastolic BPs and

    An objective of this study is to search how physical examination and diet consultation can influence those risk factors of cardiovascular disease. The subjects were 326 pilots of the “B” airline company in Korea whose total cholesterol values were over 220 mg/dl on their regular physical examinations from April 2006 to December 2008. They were divided into two groups, one who had diet consultation (an intervention group) and a control group. The physical examination components used to each group were body mass index (BMI), total cholesterol (TC), high density lipoprotein (HDL), low density lipoprotein (LDL) and triglyceride (TG). The behavioral, anthropometric and biomedical measurements were collected at each visit. This study compares and investigates the changes of serum cholesterol and also the health-behavior at each physical examination. Within the intervention group significant improvements were observed for total cholesterol, BMI (body mass index) and HDL (high density lipoprotein). The normalizing rates for cholesterol level to decrease down to lower than 200 mg/dl were 17.7% in intervention group and 8.7% in control group, which is statistically significantly higher among the intervention group. The odds ratio of diet consultation was 2.80 (95% CI=1.35–5.79), which indicates that it is a significantly contributing factor to normalize the serum cholesterol value down to lower than 200 mg/dl. Based on result, it is recommended to have regular physical examination and intensive management with diet and exercise consultation. PMID:24131872

    Walnut oil (WO) is a good source of alpha-linolenic acid. We compared the effects of WO and high-linoleic safflower oil (HLSO) on the serum lipid level and atherosclerosis development in male and female apolipoprotein (apo) E-deficient mice. The WO diet resulted in a higher level of serum cholesterol than with HLSO. Female mice fed on the WO diet had a greater lesion area in the aortic root than did those on the HLSO diet. There was no diet-dependent difference in the level of cholesterol and its oxidation products in the abdominal and thoracic aorta. These results suggest that the unpleasant effects of the WO diet on apo E-deficient mice may be attributable to alpha-linolenic acid.

  2. [Cholesterol reducing food certainly is useful].

    The effect of a low-cholesterol diet in open intervention studies depends in the long run on motivation, knowledge and dedication. The mean decrease of the serum cholesterol level is 10% (range: 0-20). Epidemiological and cohort studies clearly prove a connection between the intake of saturated fat, the serum cholesterol level and the risk of coronary heart disease and death. High-fat food slows down the clearance of the degradation products rich in cholesterol which appear in the blood after a meal and which are highly atherogenic (these products are not found at a fasting cholesterol assay). Cholesterol-reducing nutrition has additional useful effects, for instance on the blood pressure and the coagulation. The recommendations for healthy, low-cholesterol nutrition for the population as a whole apply particularly to patients with a high risk of coronary heart disease. Although advice given to individuals often has a disappointing effect, influencing the life pattern should be included in the strategy to reduce the risk of coronary heart disease.

    Mounting evidence indicates that serum cholesterol and other risk factors for cardiovascular disease intensify normative trajectories of age-related cognitive decline. However, the neural mechanisms by which this occurs remain largely unknown. To understand the impact of cholesterol on brain networks, we applied graph theory to resting-state fMRI in a large sample of early- to mid-life Veterans (N = 206, Mean age  = 32). A network emerged (centered on the banks of the superior temporal sulcus) that evidenced age-related decoupling (i.e., decreased network connectivity with age), but only in participants with clinically-elevated total cholesterol (≥180 mg/dL). Crucially, decoupling in this network corresponded to greater day-to-day disability and mediated age-related declines in psychomotor speed. Finally, examination of network organization revealed a pattern of age-related dedifferentiation for the banks of the superior temporal sulcus, again present only with higher cholesterol. More specifically, age was related to decreasing within-module communication (indexed by Within-Module Degree Z-Score) and increasing between-module communication (indexed by Participation Coefficient), but only in participants with clinically-elevated cholesterol. Follow-up analyses indicated that all findings were driven by low-density lipoprotein (LDL) levels, rather than high-density lipoprotein (HDL) or triglycerides, which is interesting as LDL levels have been linked to increased risk for cardiovascular disease, whereas HDL levels appear inversely related to such disease. These findings provide novel insight into the deleterious effects of cholesterol on brain health and suggest that cholesterol accelerates the impact of age on neural trajectories by disrupting connectivity in circuits implicated in integrative processes and behavioral control.

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.

    This invention relates to a highly accurate, rapid and simple estimation of thyroxine (T 4 ) directly from blood serum and also relates to the accurate measurement of triiodo-L-thyronine (T 3 ) directly from blood serum. More specifically, the invention relates to a rapid, specific and reliable radioimmunoassay (RIA) technique for measurement of both T 4 and T 3 in unextracted serum. The method requires very small amounts of serum, e.g., 25 microliters (μl) to measure T 4 concentration in nearly all specimens representing clinical states of eu-, hypo- and hyperthyroidism, and 250 μl to measure T 3 concentrations in specimens representing most clinical states

    Background: Dyslipidaemia is a global health issue in developed as well as in developing countries. People with type 2 Diabetes mellitus are more susceptible to develop dyslipidaemia and its related complications. The objective of the study was to assess the effect of sitagliptin a (DPP-4 inhibitor) oral antidiabetic drug on blood sugar, body weight, blood pressure and dyslipidaemia in type 2 diabetic patients. Methods: This 12 weeks open label observational study was conducted at outdoor of diabetic clinic of Sheikh Zayed Medical College/Hospital, Rahim Yar Khan in which newly diagnosed type 2 diabetic patients (n=78) with poor glycaemic control(HbA1c >7.2 percent) were selected. The patient received sitagliptin 50 mg twice daily for 12 weeks. Results: After 12 weeks treatment with sitagliptin, there was a significant reduction in the value of HbA1c from 8.184 percent±0.467 at baseline to 7.0200 percent±0.459 at 12 weeks (p<0.05). Body weight also decreased significantly from 80.21kg±7.156 at baseline to 71.74 kg±6.567 at 12 weeks (p<0.05).Systolic blood pressure decreased (SBP) decreased significantly from 138.17±6.050 mmHg at baseline to 131.22±6.311 mmHg at 12 weeks (p<0.05). Significant changes were also seen in diastolic blood pressure which decreased from 83.14±6.714 mmHg at baseline to 75.28±6.481 mmHg at 12 weeks (p<0.05). Significant reduction in the serum level of total Cholesterol (TC), triglycerides (TG) and Low density lipoprotein cholesterol (LDL-C) were detected (TC: 222.09±13.538 to 209.41±13.475 mg/dl, p<0.05; TG: 170.99±6.940 to 143.45±8.279 mg/dl, p<0.05; LDL-C 120.00±5.804 to 109.06±6.278 mg/dl, p<0.05). High density lipoprotein cholesterol (HDL-C) increased significantly from 42.99±4.836 mg/dl at baseline to 49.97±3.490 mg/dl at 12 weeks. Conclusion: Sitagliptin not only improves blood glucose control but also body weight, blood pressure and lipid profile in type 2 diabetic hyperlipidaemia patients. (author)

    Full Text Available We analyzed the blood serum of the rainbow trout in relation to various physico-chemical properties of water and diet composition. Fish were reared in two ponds that were supplied by water from different sources. The identified differences in the biochemical parameters are caused by different environmental factors in ponds and different feed composition. Low oxygen values caused by different temperatures is a key stress factor of the noted differences. Statistically significant differences are noted for AST (aspartate aminotransferase, ALT (alanine aminotransferase, triglycerides, urea and iron (0.00. Evident were also different mineral concentrations of Ca and P (0.05 as well as glucose and cholesterol (0.05.

    The effects were studied of intravenous and intramuscular administration of radioprotectives cystamine and gammaphos in dogs on the biochemical parameters of the blood serum. The activities were studied of enzymes aspartate aminotransferase, alanine aminotransferase, alkaline phosphatase, creatinine kinase, gamma-glutamyl transpeptidase, lactate dehydrogenase, malate dehydrogenase, sorbitol dehydrogenase and alpha-amylase. The contents were determined of total protein, albumin, bilirubin, urea nitrogen, creatinine, glucose, triglycerides, cholesterol, lipids, calcium, sodium and potassium. Cystamine was shown to be hepatotoxic. The intramuscular administration of gammaphos was found to be more advantageous than of cystamine. Only slight increase was observed in the activities of lactate dehydrogenase, malate dehydrogenase, and alpha-amylase. With cystamine, the changes in all biochemical parameters were most marked.

    Twenty-nine healthy volunteers aged 47–69 years old were randomly assigned to a 28-day oral intake of different dark chocolate (DC) formulations. The main group received daily 30 g of proprietary lycopene-containing (L-tug) lycosome formulation of DC with enhanced bioavailability of cocoa flavanols. Two control groups daily consumed either 30 g of regular DC alone or along with 7 mg of lycopene, which corresponds to the amount of lycopene ingested with L-tug formulation. It was found that L-tug was more efficient in reducing diastolic blood pressure (mean value of −6.22 mmHg, 95% CI: 5.00, 8.00) when compared with the regular DC group (−3.00 mmHg, P < 0.05) or the group which ingested the DC and lycopene as two separate formulations (mean reduction of −4 mmHg, 95% CI: 2.47, 6.00, P = 0.0262). Only marginal superiority for L-tug formulation in the reduction in systolic blood pressure was seen. However, the L-tug formulation was the only formulation of DC which affected serum lipids. There was a reduction in total cholesterol (from median 228.00 mg/dL [95% CI: 206.2, 242.5] to 187.00 mg/dL [95% CI: 166.2, 202.2, P < 0.05]) with corresponding decline of low-density lipoprotein (LDL) cholesterol (from a median of 166.00 mg/dL [95% CI: 130.8, 177.0] to 151.00 mg/dL [95% CI: 122.8, 167.4; P < 0.05]) at the end of the intervention period. Similar decline was seen in serum triglycerides (P < 0.05). Serum high-density lipoprotein (HDL) cholesterol, glucose levels, and C-reactive protein (CRP) values remained statistically unchanged in all study groups throughout the intervention period. A superior biological activity of the L-tug lycosome formulation of DC extending beyond its antihypertensive effect to lipid-lowering ability opens up new possibilities for the use of DC for health purposes helping to reduce daily caloric intake without compromising on the health benefits of DC consumption.

    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.

    Full Text Available Metabolomics is a powerful technology with broad applications in life science that, like other -omics approaches, requires high-quality samples to achieve reliable results and ensure reproducibility. Therefore, along with quality assurance, methods to assess sample quality regarding pre-analytical confounders are urgently needed. In this study, we analyzed the response of the human serum metabolome to pre-analytical variations comprising prolonged blood incubation and extended serum storage at room temperature by using gas chromatography-mass spectrometry (GC-MS and liquid chromatography-tandem mass spectrometry (LC-MS/MS -based metabolomics. We found that the prolonged incubation of blood results in a statistically significant 20% increase and 4% decrease of 225 tested serum metabolites. Extended serum storage affected 21% of the analyzed metabolites (14% increased, 7% decreased. Amino acids and nucleobases showed the highest percentage of changed metabolites in both confounding conditions, whereas lipids were remarkably stable. Interestingly, the amounts of taurine and O-phosphoethanolamine, which have both been discussed as biomarkers for various diseases, were 1.8- and 2.9-fold increased after 6 h of blood incubation. Since we found that both are more stable in ethylenediaminetetraacetic acid (EDTA blood, EDTA plasma should be the preferred metabolomics matrix.

    The aim of this meta-analysis was to investigate the effects of atorvastatin on serum levels of high-sensitivity C-reactive protein (hs-CRP) and total cholesterol in atrial fibrillation (AF) patients in Asia. By searching English and Chinese language-based electronic databases (ie, PubMed, EBSCO, Ovid, SpringerLink, Wiley, Web of Science, Wanfang database, China National Knowledge Infrastructure, and VIP database), we identified 13 studies relevant to our topic of interest. Data were collected from the 13 studies and analyzed with Comprehensive Meta-Analysis software (version 2.0, Biostat Inc., Englewood, New Jersey). Initially, our database searches retrieved 356 studies (45 in English, 311 in Chinese). Thirteen studies were selected for the meta-analysis following stringent criteria. The data included 1239 patients with AF, of whom 634 were treated with atorvastatin and included in the treatment group, and 605 patients were treated with conventional treatment and included in the control group. The results of our meta-analysis suggested that the serum levels of hs-CRP (mg/L) and total cholesterol (mmol/L) in the treatment group were significantly lower than those of the control group (hs-CRP: standardized mean difference = 0.962; 95% CI, 0.629-1.295, P < 0.001; total cholesterol: standardized mean difference = 1.400; 95% CI, 0.653-2.146, P < 0.001). The findings of this study suggest that atorvastatin may be very effective in decreasing serum levels of hs-CRP and total cholesterol to prevent cardiovascular events.

    Full Text Available It has been reported that higher folate intake from food and supplementation is associated with decreased blood pressure (BP. The association between serum folate concentration and BP has been examined in few studies. We aim to examine the association between serum folate and BP levels in a cohort of young Chinese women.We used the baseline data from a pre-conception cohort of women of childbearing age in Liuyang, China, for this study. Demographic data were collected by structured interview. Serum folate concentration was measured by immunoassay, and homocysteine, blood glucose, triglyceride and total cholesterol were measured through standardized clinical procedures. Multiple linear regression and principal component regression model were applied in the analysis.A total of 1,532 healthy normotensive non-pregnant women were included in the final analysis. The mean concentration of serum folate was 7.5 ± 5.4 nmol/L and 55% of the women presented with folate deficiency (< 6.8 nmol/L. Multiple linear regression and principal component regression showed that serum folate levels were inversely associated with systolic and diastolic BP, after adjusting for demographic, anthropometric, and biochemical factors.Serum folate is inversely associated with BP in non-pregnant women of childbearing age with high prevalence of folate deficiency.

  1. LIPID METABOLISM INDICES AND FATTY ACIDS PROFILE IN THE BLOOD SERUM OF BROILER CHICKENS FED A DIET WITH LIGNOCELLULOSE

    Directory of Open Access Journals (Sweden)

    M Bogusławska-Tryk

    Full Text Available ABSTRACT The aim of the research was to determine lipid metabolism indices and fatty acid profile in the blood serum of Ross 308 chickens (n = 48, fed a finisher mixture supplemented with 0, 0.25, 0.5 and 1.0% of lignocellulose. The feeding trial lasted from 21 to 42 d of the birds' age. Blood samples were collected from each chicken at 42d of age from the pterygoid canal vein. In the blood serum the content of triglycerides (TG, total cholesterol (TCHOL and high density lipoprotein (HDL fraction was determined by the spectrophotometric method. The fatty acids concentration was estimated with the use of the gas chromatography method. Lignocellulose in doses of 0.5 and 1.0% significantly reduced the concentration of triglycerides and low density lipoprotein (LDL fraction. Saturated fatty acids (SFA and monounsaturated fatty acids (MUFA content was not affected by dietary treatments whereas lignocellulose significantly influenced the profile of polyunsaturated fatty acids (PUFA from n-3 and n-6 families. Insoluble fiber decreased (p< 0.05 serum concentration of a-linolenic acid (C18:3n-3 and increased share of docosahexaenoic acid (C22:6n-3, dihomogammalinolenic acid (C20:3n-6 and arachidonic acid (C20:4n-6 in total PUFA, compared to the control birds. The results of the present study have shown that the incorporation of limited amounts of lignocellulose into the broiler diet can influence the lipid metabolism in the chickens.

    Background: Vitamin D deficiency, defined as a serum 25-hydroxyvitamin D [25(OH)D] concentration light. Objective: We tested the hypothesis that, in vitamin D-deficient adults, the replenishment of vitamin D with UVB exposure would lower LDL-cholesterol concentrations compared with the effect of oral vitamin D 3 supplementation. Design: We performed a randomized clinical trial in vitamin D-deficient adults and compared vitamin D replenishment between subjects who received oral vitamin D 3 ( n = 60) and those who received narrow-band UVB exposure ( n = 58) ≤6 mo. Results: There was no difference in the change from baseline LDL-cholesterol concentrations between oral vitamin D 3 and UVB groups (difference in median of oral vitamin D 3 minus that of UVB: 1.5 mg/dL; 95% CI: -5.0, 7.0 mg/dL). There were also no differences within groups or between groups for changes in total or HDL cholesterol or triglycerides. Transcriptional profiling of skin and blood, however, revealed significant upregulation of immune pathway signaling with oral vitamin D 3 but significant downregulation with UVB. Conclusions: Correcting vitamin D deficiency with either oral vitamin D 3 or UVB does not improve the lipid profile. Beyond cholesterol, these 2 modalities of raising 25(OH)D have disparate effects on gene transcription.

    The influence of a radiosensitizer, metronidazole, on the free thymidine content of blood serum of irradiated mice was studied in aerobic and hypoxic conditions. A heated metronidazole solution (1 mg/g) was administered intraperitoneally 30 min before irradiation of animals with a dose of 3 Gy. Thymidine concentration in blood serum was determined by the radioimmunological technique. The influence of metronidazole on the level of thymidinemia was only noted in the animals exposed under hypoxic conditions

    The goal of this work was to determine if immediate versus postponed centrifugation of samples affects the levels of serum potassium. Twenty participants donated normal venous blood that was collected in four serum separator tubes per donor, each of which was analyzed at 0, 1, 2, or 4 hr on the Siemens Advia 1800 autoanalyzer. Coefficients of variation (CVs) for potassium levels ranged from 0% to 7.6% with a mean of 3 ± 2%. ANOVA testing of the means for all 20 samples showed a P-value of 0.72 (>0.05) indicating that there was no statistically significant difference between the means of the samples at the four time points. Sixteen samples were found to have CVs that were ≤5%. Two samples showed increases of potassium from the reference range to levels higher than the upper reference limit, one of which had a 4-hr value that was within the reference or normal range (3.5-5 mEq/l). Overall, most samples were found to have reproducible levels of serum potassium. Serum potassium levels from stored whole blood collected in serum separator tubes are, for the most part, stable at room temperature for at least 4 hr prior to analysis. However, some samples can exhibit significant fluctuations of values. © 2015 Wiley Periodicals, Inc.

    This study aimed at investigating the relationship between the lipid index (WS) in the examined cadets and duration of exposure to +Gz in the human centrifuge. The study involved 19 first-year cadets of the Polish Air Force Academy in Dęblin. Tests in the human centrifuge were repeated twice, i.e. prior to (test I) and 45 days after (test II). After exposure to +Gz, the examined cadets were divided into 2 groups. Group I (N=11) included cadets subjected to a shorter total duration of exposure to +Gz, while group II (N=8) included cadets with a longer total duration of exposure to +Gz. Total cholesterol (TC), high density lipoprotein (HDL), triglycerides (TG), and apolipoproteins A1 and B were assayed in blood serum prior to (assay A) and after (assay B) both exposures to +Gz. Low density lipoprotein (LDL) level was estimated from the Friedewald formula. WS is an own mathematical algorithm. WS was higher in group II, assay A - 10.0 and B - 10.08 of test I in the human centrifuge than in group I where the WS values were 6.91 and 6.96, respectively. WS was also higher in group II in assay A - 10.0 and B -10.1 of test II in the human centrifuge than in group I - 6.96 and 6.80, respectively. The higher value of WS in group II, both after the first and second exposure to +Gz in human centrifuge, in comparison with group I, indicated its usefulness for determination of the maximum capability of applying acceleration of the interval type during training in the human centrifuge.

    Multiple Sclerosis (MS) is an inflammatory demyelinating disorder in which remyelination failure contributes to persistent disability. Cholesterol is rate-limiting for myelin biogenesis in the developing CNS; however, whether cholesterol insufficiency contributes to remyelination failure in MS, is unclear. Here, we show the relationship between cholesterol, myelination and neurological parameters in mouse models of demyelination and remyelination. In the cuprizone model, acute disease reduces serum cholesterol levels that can be restored by dietary cholesterol. Concomitant with blood-brain barrier impairment, supplemented cholesterol directly supports oligodendrocyte precursor proliferation and differentiation, and restores the balance of growth factors, creating a permissive environment for repair. This leads to attenuated axon damage, enhanced remyelination and improved motor learning. Remarkably, in experimental autoimmune encephalomyelitis, cholesterol supplementation does not exacerbate disease expression. These findings emphasize the safety of dietary cholesterol in inflammatory diseases and point to a previously unrecognized role of cholesterol in promoting repair after demyelinating episodes.

    Full Text Available ABCA1 and ABCG1 genes encode the cholesterol transporter proteins that play a key role in cholesterol and phospholipids homeostasis. This study was aimed at evaluating and comparing ABCA1 and ABCG1 genes expression in metabolic syndrome patients and healthy individuals. This case-control study was performed on 36 patients with metabolic syndrome and the same number of healthy individuals in Hamadan (west of Iran during 2013-2014. Total RNA was extracted from mononuclear cells and purified using RNeasy Mini Kit column. The expression of ABCA1 and ABCG1 genes was performed by qRT-PCR. Lipid profile and fasting blood glucose were measured using colorimetric procedures. ABCG1 expression in metabolic syndrome patients was significantly lower (about 75% compared to that of control group, while for ABCA1 expression, there was no significant difference between the two studied groups. Comparison of other parameters such as HDL-C, FBS, BMI, waist circumference, and systolic and diastolic blood pressure between metabolic syndrome patients and healthy individuals showed significant differences (P<0.05. Decrease in ABCG1 expression in metabolic syndrome patients compared to healthy individuals suggests that hyperglycemia, related metabolites, and hyperlipidemia over the transporter capacity resulted in decreased expression of ABCG1. Absence of a significant change in ABCA1 gene expression between two groups can indicate a different regulation mechanism for ABCA1 expression.

    Cardiovascular disease (CVD) is currently the primary cause of morbidity and mortality. (1) Assess the 10 years risk for CVD in Argentinean blood donors, according to Framingham score (updated by ATP III), (2) evaluate the prevalence of the MS, (3) evaluate non HDL-cholesterol level in this population as other risk for CVD. A prospective, epidemiological, transversal study was performed to evaluate 585 volunteer blood donors for two years. Non HDL-C was calculated as total cholesterol minus HDL-C and we evaluated the 10 years risk for CVD according to Framingham score (updated by ATP III). Metabolic syndrome prevalence was estimated according to ATP III and IDF criteria. Non HDL-C was (media±SD) 178.3±48.0 mg/dl in participants with MS and 143.7±39.3 mg/dl without MS (ATPIII) and 160.1±43.6 mg/dl in participants with MS and 139.8±43.1 mg/dl without MS (IDF). Participants with MS presented an OR of 3.1; IC 95% (2-5) of CVD according to de Framingham score. Individuals with MS and elevated non HDL-C are at a higher estimated risk for cardiovascular events in the next 10 years according to the Framingham risk score. Copyright © 2014.

    Elevated serum triglyceride (TG) and high-density-lipoprotein cholesterol (HDL-C) levels are common in drinkers. The fast-metabolizing alcohol dehydrogenase-1B encoded by the ADH1B*2 allele (vs. ADH1B*1/*1 genotype) and inactive aldehyde dehydrogenase-2 encoded by the ALDH2*2 allele (vs. ALDH2*1/*1 genotype) modify ethanol metabolism and are prevalent (≈90% and ≈40%, respectively) in East Asians. We attempted to evaluate the associations between the ADH1B and ALDH2 genotypes and lipid levels in alcoholics. The population consisted of 1806 Japanese alcoholic men (≥40 years) who had undergone ADH1B and ALDH2 genotyping and whose serum TG, total cholesterol, and HDL-C levels in the fasting state had been measured within 3 days after admission. High serum levels of TG (≥150 mg/dl), HDL-C (>80 mg/dl), and low-density-lipoprotein cholesterol (LDL-C calculated by the Friedewald formula ≥140 mg/dl) were observed in 24.3%, 16.8%, and 15.6%, respectively, of the subjects. Diabetes, cirrhosis, smoking, and body mass index (BMI) affected the serum lipid levels. Multivariate analysis revealed that the presence of the ADH1B*2 allele and the active ALDH2*1/*1 genotype increased the odds ratio (OR; 95% confidence interval) for a high TG level (2.22 [1.67-2.94] and 1.39 [0.99-1.96], respectively), and decreased the OR for a high HDL-C level (0.37 [0.28-0.49] and 0.51 [0.37-0.69], respectively). The presence of the ADH1B*2 allele decreased the OR for a high LDL-C level (0.60 [0.45-0.80]). The ADH1B*2 plus ALDH2*1/*1 combination yielded the highest ORs for high TG levels and lowest OR for a high HDL-C level. The genotype effects were more prominent in relation to the higher levels of TG (≥220 mg/dl) and HDL-C (≥100 mg/dl). The fast-metabolizing ADH1B and active ALDH2, and especially a combination of the two were strongly associated with higher serum TG levels and lower serum HDL-C levels of alcoholics. The fast-metabolizing ADH1B was associated with lower serum LDL

    Marital status has been recognized as a significant health-influencing factor, including cardiovascular disease (CVD) risk. The aim of the present paper was to evaluate whether eating habits mediate the relationship between marital status and levels of CVD risk factors among apparently healthy men and women from the ATTICA Study. During 2001-2002, we randomly enrolled 1514 men (18-87 years old) and 1528 women (18-89 years old) from the Attica area, Greece; the sampling was stratified by the age-gender distribution of the region. Participants underwent clinical, anthropometric and psychological assessment. Food consumption was assessed through a semi-quantitative food frequency questionnaire. Participants were classified as never married, married, divorced and widowed. Discriminant analysis revealed that vegetable consumption, followed by red meat, potatoes, poultry, and soft drinks were the factors with the higher discriminating ability among the food groups studied. In particular, dietary patterns of never married participants were characterized by the consumption of potatoes and red meat, those of married participants by nuts, legumes and fish, those of divorced participants by fruits, cereals and soft drinks, whereas those of widowed participants by dairy, vegetables, sweets and poultry. In addition, never married and divorced participants reported eating fast-foods more frequently and drink less alcohol compared to married or widowed participants. After controlling for potential confounders (i.e., age, gender, physical activity, anxiety score and smoking habits), the reported marital status of the participants was associated only with body mass index and total serum cholesterol levels. When the analysis was repeated after taking into account the information on dietary habits by creating four "new" dietary-adjusted marital status groups, no significant association was revealed between marital status and body mass index and blood cholesterol levels.

    The interaction of pentavalent and hexavalent 99 Mo compounds with rat and human serum was monitored in vitro by paper electrophoresis after incubation for one hour at 37 0 C. Hexavalent 99 Mo is not capable of interaction and, via sulfur ligands, forms unstable and unspecific bonds to the whole spectrum of serum proteins, in particular to albumin. Pentavalent 99 Mo binds strongly to alpha-2-macroglobulin in a ratio of 2 : 1; according to the nature of the ligand, it forms somewhat unstable bonds to albumin, beta-1-globulin and gamma-2-globulin.

    Full Text Available Although altered lipid metabolism has been extensively implicated in the pathogenesis of Alzheimer disease (AD through cell biological, epidemiological, and genetic studies, the molecular mechanisms linking cholesterol and AD pathology are still not well understood and contradictory results have been reported. We have used a Mendelian randomization approach to dissect the causal nature of the association between circulating lipid levels and late onset AD (LOAD and test the hypothesis that genetically raised lipid levels increase the risk of LOAD.We included 3,914 patients with LOAD, 1,675 older individuals without LOAD, and 4,989 individuals from the general population from six genome wide studies drawn from a white population (total n=10,578. We constructed weighted genotype risk scores (GRSs for four blood lipid phenotypes (high-density lipoprotein cholesterol [HDL-c], low-density lipoprotein cholesterol [LDL-c], triglycerides, and total cholesterol using well-established SNPs in 157 loci for blood lipids reported by Willer and colleagues (2013. Both full GRSs using all SNPs associated with each trait at p<5×10-8 and trait specific scores using SNPs associated exclusively with each trait at p<5 × 10-8 were developed. We used logistic regression to investigate whether the GRSs were associated with LOAD in each study and results were combined together by meta-analysis. We found no association between any of the full GRSs and LOAD (meta-analysis results: odds ratio [OR]=1.005, 95% CI 0.82-1.24, p = 0.962 per 1 unit increase in HDL-c; OR=0.901, 95% CI 0.65-1.25, p=0.530 per 1 unit increase in LDL-c; OR=1.104, 95% CI 0.89-1.37, p=0.362 per 1 unit increase in triglycerides; and OR=0.954, 95% CI 0.76-1.21, p=0.688 per 1 unit increase in total cholesterol. Results for the trait specific scores were similar; however, the trait specific scores explained much smaller phenotypic variance.Genetic predisposition to increased blood cholesterol and

    Rapid diagnostic tests (RDTs) based on the detection of specific antibodies in serum are commonly used for the diagnosis of visceral leishmaniasis (VL). Several commercial kits are available, and some of them allow the use of whole-blood samples instead of serum. An RDT is much more user-friendly for blood samples than for serum samples. In this study, we examined the sensitivities and specificities of six different commercially available immunochromatographic tests for their accuracy in detecting Leishmania infection in whole blood and serum of parasitologically confirmed VL cases. This study was performed in areas of India and Nepal where VL is endemic. A total of 177 confirmed VL cases, 208 healthy controls from areas of endemicity (EHCs), 26 malaria patients (MP), and 37 tuberculosis (TB) patients were enrolled. The reproducibilities of the blood and serum results and between-reader and between-laboratory results were tested. In India, the sensitivities of all the RDTs ranged between 94.7 and 100.0%, with no significant differences between whole blood and serum. The specificities ranged between 92.4 and 100.0%, except for the specificity of the Onsite Leishmania Ab RevB kit, which was lower (33.6 to 42.0%). No differences in specificities were observed for blood and serum. In Nepal, the sensitivities of all the test kits, for whole-blood as well as serum samples, ranged between 96.3 and 100.0%, and the specificities ranged between 90.1 and 96.1%, again with the exception of that of the Onsite Leishmania Ab RevB test, which was markedly lower (48.7 to 49.3%). The diagnostic accuracies of all the tests, except for one brand, were excellent for the whole-blood and serum samples. We conclude that whole blood is an adequate alternative for serum in RDTs for VL, with sensitivities and specificities comparable to those obtained in serum samples, provided that the test kit is of overall good quality.

    Postpartum depression (PPD) is a psychiatric complication of childbirth affecting 10–20% of new mothers and has negative impact on both mother and infant. Serum lipid levels have been related to depressive disorders, but very limited literatures are available regarding the lipid levels in women with postpartum depression. The present study is aimed to examine the association of serum lipids with the development of postpartum depressive symptoms. This is a cross sectional study conducted at a tertiary care hospital in South India. Women who came for postpartum check-up at 6th week post-delivery were screened for PPD (September 2014-October 2015). Women with depressive symptoms were assessed using EPDS (Edinburgh Postnatal Depression Scale). The study involved 186 cases and 250 controls matched for age and BMI. Serum levels of lipid parameters were estimated through spectrophotometry and the atherogenic indices were calculated in all the subjects. Low serum levels of Total Cholesterol (TC) and High Density Lipoprotein cholesterol (HDL-c) were significantly low in PPD women with severe depressive symptoms. The study recorded a significant negative correlation between HDL-c and the EPDS score in PPD women (r = -0.140, p = 0.05). Interestingly, the study also observed a significant negative correlation between Body Mass Index (BMI) and EPDS scores in case group (r = -0.146, p = 0.047), whereas a positive correlation between the same in controls (r = 0.187, p = 0.004). Our study demonstrated that low levels of serum HDL-c is correlated with the development of severe depressive symptoms in postpartum women. Study highlights the role of lipids in the development of postpartum depressive symptoms. PMID:29444162

    The content of fatty acid (FA) triglycerides in food and biological media is predicting traditionally using gas and liquid chromatographic methods. Named techniques aren't available for clinical labs due to their complexity. So, our objective was to develop the method and apparatus for rapid assay of a few clinically important FA as the saturated palmitic, mono unsaturated oleic and others in serum using near infrared spectrometer. As a result, the applicability of the FT spectrometer in the wavelength range of 0.9 -1.8 μ to analyze these FA in serum without sample preparation was confirmed. Besides, measurement specifications were determined and a correlations of the absorption spectra and contents of total triglycerides and cholesterol, palmitic, oleic, linoleic and arachidonic FA in serum were established

    We present the optical diagnosis of dengue virus infection in human blood serum using Raman spectroscopy. Raman spectra were acquired from 18 blood serum samples using a laser at 532 nm as the excitation source. A multivariate regression model based on partial least-squares regression is developed that uses Raman spectra to predict dengue infection with leave-one-sample-out cross validation. The prediction of dengue infection by our model yields correlation coefficient r 2 values of 0.9998 between the predicted and reference clinical results. The model was tested for six unknown human blood sera and found to be 100% accurate in accordance with the clinical results. (letter)

    The effects of a daily fish oil supplement rich in eicosapentaenoic acid were studied in 11 stable continuous ambulatory peritoneal dialysis (CAPD) patients. Serum lipids, platelet aggregation studies, and template bleeding times were determined before and after 4 weeks of fish oil treatment. The lipid studies were repeated approximately 20 weeks after stopping fish oil supplement. At the end of the treatment period, serum triglycerides (mean +/- SEM) decreased from 297 +/- 42 to 211 +/- 29 mg/dL (P less than .01), high density lipoprotein (HDL) cholesterol fell from 45 +/- 3 to 41 +/- 3 mg/dL (P less than .05), and low density lipoprotein (LDL) cholesterol increased from 172 +/- 16 to 208 +/- 19 mg/dL (P less than .05). After discontinuing the fish oil supplement, the triglycerides increased to 278 +/- 39 mg/dL, which was no different than the value before fish oil treatment. No significant changes occurred in template bleeding time (TBT), platelet count, hematocrit, or platelet aggregation response. Clinically important uremic bleeding was not apparent. We conclude that in CAPD patients a fish oil supplement favorably effects hypertriglyceridemia and can be ingested without promoting uremic bleeding. The likely beneficial impact on atherogenesis resulting from the lowering of the triglycerides may, however, be counteracted by concomitant changes in HDL- and LDL-cholesterol.

    Atherosclerotic cardiovascular disease (ASCVD) is a leading cause of morbidity and mortality in developed countries. The management of blood cholesterol through use of 3-hydroxy-3-methyl-glutaryl-CoA (HMG-CoA) reductase inhibitors (statins) in at-risk patients is a pillar of medical therapy for the primary and secondary prevention of cardiovascular disease. The recent 2013 American College of Cardiology/American Heart Association guideline on managing blood cholesterol provides an important framework for the effective implementation of risk-reduction strategies. The guideline identifies four cohorts of patients with proven benefits from statin therapy and streamlines the dosing and monitoring recommendations based on evidence from published, randomized controlled trials. Primary care physicians and cardiologists play key roles in identifying populations at elevated ASCVD risk. In providing a practical management overview of the current blood cholesterol guideline, we facilitate more informed discussions on treatment options between healthcare providers and their patients.

    The effects of 3 wk on a diet rich in monounsaturated rapeseed oil were compared with those of a diet containing sunflower oil within a lipid-lowering diet. Ninety-five subjects with moderate hyperlipoproteinemia were randomly assigned to one of the two well-controlled diets prepared at the hospital kitchen. Total serum, low-density- and high-density-lipoprotein cholesterol concentrations decreased by 15%, 16%, and 11% (P oil diet and by 16%, 14%, and 13% (P oil diet. Serum triglycerides decreased more markedly (by 29%, P oil than on the rapeseed oil diet (14%, P oil diet but decreased on the sunflower oil diet. There was an increase in the alpha-tocopherol concentrations after both diets. The findings indicate that low erucic acid rapeseed oil can replace oils and fats rich in polyunsaturated fatty acids in a lipid-lowering diet.

    The present study examined the association between uric acid levels and high blood pressure in a multiethnic study of Chinese children and adolescents. The participants were divided into four different groups according to the uric acid quartiles. Three logistic regression models were conducted to investigate the relationship between the high blood pressure and uric acid levels. Model 1 adjusted age, sex and ethnicity. Model 2 adjusted age, sex, ethnicity, total cholesterol, high-density lipoprotein, low-density lipoprotein, triglycerides, estimated glomerular filtration rate, fasting glucose and waist circumference. Model 3 adjusted all the confounding factors in model 2 except the waist circumference and BMI. The concentrations of uric acid in high blood pressure participants and normotensive participants were compared with or without adjustment for confounding factors. A total of 3778 participants aged 10-15 years from the Xinjiang Congenital Heart Disease Survey were included in the present study. The percentages of the high blood pressure in the four different uric acid quartiles were 7.4, 8.6, 9.6 and 11.8%, respectively. In model 1, 2 and 3 of the logistic regression, the participants in the third and fourth uric acid quartiles had significantly higher chance of suffering the high blood pressure when compared with the participants in the first uric acid quartile [odds ratio 1.608, 1.587, 1.597, P = 0.005, 0.015, 0.015, respectively, between participants in the first quartile and the third quartile; odds ratio 1.981, 1.945, 1.810, P = 0.001, 0.002, 0.007, respectively, between participants in the first quartile and the fourth quartile). The concentrations of serum uric acid were 220.7 μmol/l in high blood pressure participants and 204.1 μmol/l in normotensive participants (P = 0.024). After adjustment for confounding factors, the concentrations of serum uric acid were 219.7 vs. 204.5 μmol/l in one model (P high blood pressure.

    Food habits vary by socio-economic group and geographic area. Data on socio-economic differences in food habits and in serum total cholesterol concentration from Russia are scarce. Our aim was to examine changes and educational differences in serum total cholesterol and in the consumption of major sources of saturated fat in two geographically neighbouring areas, Russian and Finnish Karelia, and to examine whether the foods associated with serum total cholesterol are different in the two areas. Data from cross-sectional risk factor surveys from years 1992, 1997, 2002 and 2007 in the district of Pitkäranta, the Republic of Karelia, Russia (n = 2672), and North Karelia, Finland (n = 5437), were used. The analyses included two phases. 1) To examine the differences in cholesterol by education, the means and 95% confidence intervals for education groups were calculated for each study year. 2) Multivariate linear regression analysis was employed to examine the role of butter in cooking, butter on bread, fat-containing milk and cheese in explaining serum total cholesterol. In these analyses, the data for all four study years were combined. In Pitkäranta, serum total cholesterol fluctuated during the study period (1992-2007), whereas in North Karelia cholesterol levels declined consistently. No apparent differences in cholesterol levels by education were observed in Pitkäranta. In North Karelia, cholesterol was lower among subjects in the highest education tertile compared to the lowest education tertile in 1992 and 2002. In Pitkäranta, consumption of fat-containing milk was most strongly associated with cholesterol (β=0.19, 95% CI 0.10, 0.28) adjusted for sex, age, education and study year. In North Karelia, using butter in cooking (β=0.09, 95% CI 0.04, 0.15) and using butter on bread (β=0.09, 95% CI 0.02, 0.15) had a significant positive association with cholesterol. In the two geographically neighbouring areas, the key foods influencing serum cholesterol levels

    To investigate the change of adipocyte fatty acid-binding protein (FABP4) in maternal serum and umbilical cord blood and FABP4 mRNA placental expression in patients with preeclampsia (PE). A total of 60 women with PE and 60 normal pregnant women as control participated in this study.All are admitted to Fujian Maternity and Children Health Hospital for delivery from December 2008 to October 2009. Patients with PE were divided into early-onset group (n = 30, presented at ≤ 34 weeks of gestation) and late-onset group (n = 30, presented at > 34 weeks of gestation), with 30 normal pregnant women as early control group (≤ 34 weeks of gestation) and 30 as late control group (> 34 weeks of gestation). Enzyme-linked immunosorbent assay (ELISA) was used to detect FABP4, fasting serum glucose, fasting insulin (FINS) in maternal serum and FABP4 in umbilical cord blood. Real-time fluorescent quantitative reverse transcription PCR was used to detect placental FABP4 mRNA expression. Furthermore, clinical and biochemical parameters were recorded, such as body mass index (BMI), systolic pressure (SP), diastolic pressure (DP), mean arterial pressure (MAP), total cholesterol (TC), triglyceride (TG), low density lipoprotein (LDL), high density lipoprotein (HDL), creatinine (Cr), uric acid (UA), glomerular filtration rate (GFR), 24 hours urine protein in pregnant women and neonatal weight.

    Lysyl oxidase (LOX) expression is elevated in colorectal cancer (CRC) tissue and associated with disease progression. A blood test may form a more acceptable diagnostic test for CRC although LOX has not previously been measured in the serum. We therefore sought to determine the clinical usefulness of a serum LOX test for CRC in a symptomatic population. Adult patients referred to a hospital colorectal clinic with bowel symptoms completed a questionnaire and provided a blood sample for serum LOX measurement. Associations between presenting symptoms, serum LOX concentrations and outcomes of investigations were tested by univariate and multivariate analyses to determine if serum LOX was clinically useful in the prediction of CRC. LOX expression in CRC and adjacent colon biopsies was evaluated by ELISA and immunohistochemistry. Thirty-one cases of colorectal cancer and 16 high-risk polyps were identified from a total of 962 participants. There was no association between serum LOX concentration and the presence of CRC, high-risk polyps or cancers at any site. LOX expression was significantly increased in CRC tissue compared to adjacent colon. Despite overexpression of LOX in CRC tissue, elevated serum levels could not be demonstrated. Serum LOX measurement is therefore not a clinically useful test for CRC. Copyright © 2013 Elsevier Ltd. All rights reserved.

    Chromium picolinate is used in the poultry diet because of its antistress effects in addition to the fact that the requirement for it is increased during stress. This study was conducted to determine if the negative effects of high ambient temperature (34 degrees C) on egg production, egg quality, antioxidant status, and cholesterol and mineral content of egg yolk could be alleviated by combination of chromium picolinate and biotin (0.6/2.0; Diachrome, as formulated by Nutrition 21 Inc.), in laying Japanese quails (Coturnix coturnix japanica). Quails (n= 240; 50 d old) were divided into 8 groups, 30 birds per group. The quails were fed either a basal diet or the basal diet supplemented with 2, 4, or 8 mg of Diachrome/kg diet. Birds were kept at 22 degrees C and 53% relative humidity (RH). At 14 wk of age, the thermoneutral (TN) group remained in the same temperature as at the beginning of experiment, whereas the heat stress (HS) group was kept in an environment-controlled room (34 degrees C and 41% RH) for 3 wk. Heat exposure decreased performance when the basal diet was fed (p = 0.001). Diachrome supplementation at 4 and 8 mg/kg diet, increased feed intake (p = 0.05), egg production (p = 0.05), feed efficiency (p = 0.01), egg weight (p = 0.05), and Haugh unit (p = 0.01) in quails reared under heat stress conditions. Heat exposure increased concentrations of serum malondialdehyde (MDA) (p = 0.001), glucose, and cholesterol (p = 0.01), which were elevated by supplemental Diachrome (p < or = 0.05). Egg yolk Cr, Zn, and Fe (p = 0.01) concentrations increased linearly, whereas MDA and cholesterol concentrations decreased (p = 0.05) as dietary Diachrome supplementation increased in HS groups. Similar effects of supplementation on serum levels of glucose and cholesterol (p = 0.05) and egg yolk concentrations of cholesterol (p = 0.05) and Cr (p = 0.01) were observed in TN groups. No significant differences in other values were observed in the TN groups. Results of the

    Geraniol (G) is a natural isoprenoid present in the essential oils of several aromatic plants, with various biochemical and pharmacologic properties. Nevertheless, the mechanisms of action of G on cellular metabolism are largely unknown. We propose that G could be a potential agent for the treatment of hyperlipidemia that could contribute to the prevention of cardiovascular disease. The aim of the present study was to advance our understanding of its mechanism of action on cholesterol and TG metabolism. NIH mice received supplemented diets containing 25, 50, and 75 mmol G/kg chow. After a 3-week treatment, serum total-cholesterol and triglyceride levels were measured by commercial kits and lipid biosynthesis determined by the [(14)C] acetate incorporated into fatty acids plus nonsaponifiable and total hepatic lipids of the mice. The activity of the mRNA encoding HMGCR-the rate-limiting step in cholesterol biosynthesis-along with the enzyme levels and catalysis were assessed by real-time RT-PCR, Western blotting, and HMG-CoA-conversion assays, respectively. In-silico analysis of several genes involved in lipid metabolism and regulated by G in cultured cells was also performed. Finally, the mRNA levels encoded by the genes for the low-density-lipoprotein receptor (LDLR), the sterol-regulatory-element-binding transcription factor (SREBF2), the very-low-density-lipoprotein receptor (VLDLR), and the acetyl-CoA carboxylase (ACACA) were determined by real-time RT-PCR. Plasma total-cholesterol and triglyceride levels plus hepatic fatty-acid, total-lipid, and nonsaponifiable-lipid biosynthesis were significantly reduced by feeding with G. Even though an up-regulation of the mRNA encoding HMGCR occurred in the G treated mouse livers, the protein levels and specific activity of the enzyme were both inhibited. G also enhanced the mRNAs encoding the LDL and VLDL receptors and reduced ACACA mRNA, without altering the transcription of the mRNA encoding the SREBF2. The following

    Extra virgin olive oil (EVOO) major and minor component anti-inflammatory effect on aorta was evaluated; Wistar rats were fed (9 weeks) on either a high-cholesterol diet (HCD) or a HCD supplemented with oils, i.e. EVOO, sunflower oil (SO), high-oleic sunflower oil (HOSO), or oil-products modified to their phenolic content, i.e. phenolics deprived-EVOO [EVOO(-)], SO enriched with the EVOO phenolics [SO(+)], HOSO enriched with the EVOO phenolics [HOSO(+)]. HCD induced dyslipidemia and resulted in higher aorta adhesion molecules levels at euthanasia. Groups receiving EVOO, EVOO(-), HOSO, HOSO(+) presented higher serum TC and LDL-c levels compared to cholesterol-fed rats; attenuation of aorta E-selectin levels was also observed. In EVOO/EVOO(-) groups, aorta vascular endothelial adhesion molecule-1 (VCAM-1) was lower compared to HCD animals. SO/SO(+) diets had no effect on endothelial dysfunction amelioration. Overall, our results suggest that major and/or minor EVOO constituents improve aorta E-selectin and VCAM-1, while serum lipids do not benefit.

    In the recent past, low cholesterol eggs enriched with vitamin-E and omega-3 fatty acid have been developed and are marketed under different brands claiming them as heart friendly. The influence of these eggs (smart eggs) on lipid profile of rats was evaluated in comparison to that of the standard eggs. Data of 4 week dietary treatment revealed that total plasma cholesterol, low density lipoprotein (LDL) and very low density lipoprotein (VLDL) cholesterol increased only 22% in rats fed on diet containing 4 smart eggs per kg of semi-synthetic diet in contrast to the increase of more than 100 % when fed on diet containing standard eggs. The results suggest that it is not the low cholesterol content alone but also vitamin E and omega-3 fatty acids present in smart eggs that act synergically to prevent a substantial change in blood lipid profile and impose no serious risk to the health of the consumers.

    Ghrelin is known to play a role in glucose metabolism and in beta-cell function. There are controversies regarding the role of ghrelin polymorphisms in diabetes and diabetes-related phenotypes. The objective of this study was to examine polymorphisms of the ghrelin gene in a Korean cohort and investigate associations between them and susceptibility to type 2 diabetes and its related phenotypes. The ghrelin gene was sequenced to identify polymorphisms in 24 DNA samples. Common variants were then genotyped in 760 type 2 diabetic patients and 641 nondiabetic subjects. Genetic associations with diabetes-related phenotypes were also analyzed. Nine polymorphisms were identified, and four common polymorphisms [g.-1500C>G, g.-1062G > C, g.-994C > T, g.+408C > A (Leu72Met)] were genotyped in a larger study. The genotype distributions of these four common polymorphisms in type 2 diabetes patients were similar to those of normal nondiabetic controls. However, these four common polymorphisms were variably associated with several diabetes-related phenotypes, such as high-density lipoprotein (HDL) cholesterol, fasting plasma glucose, and homeostasis model assessment of insulin resistance. In particular, subjects harboring g.-1062C were associated with a lower serum HDL cholesterol level after adjusting for other variables (P = 0.0004 or 0.01 after Bonferroni correction for 24 tests). The aforementioned four common polymorphisms in the ghrelin gene were not found to be significantly associated with susceptibility to type 2 diabetes mellitus in the Korean population. However, the common polymorphism g.-1062G > C in the promoter region of the ghrelin gene was found to be significantly associated with serum HDL cholesterol levels.

    Full Text Available Background: Hypercholesterolemia is a major risk factor for coronary heart disease. Clinical studies have shown that lowering elevated serum cholesterol levels, particularly low-density lipoprotein cholesterol (LDL-C, is beneficial for patients with borderline to mildly elevated serum total cholesterol (TC levels (5.0–6.0 mmol/L. Policosanol is a cholesterol-lowering drug made from purified sugar cane wax. The therapeutic range of policosanol is 5 to 20 mg/d. Objective: This study investigated the efficacy and tolerability of policosanol 5 mg/d in patients with borderline to mildly elevated serum TC levels. Methods: This 14-week, single-center, prospective, double-blind, placebo-controlled, parallel-group, comparative study was conducted in men and women aged 25 to 75 years with a serum TC level ≥4.8 to <6.0 mmol/L. After a 6-week run-in period in which patients were placed on therapeutic lifestyle changes, in particular a cholesterol-lowering diet, patients were randomly assigned to receive policosanol 5-mg tablets or placebo tablets once daily with the evening meal for 8 weeks, and the diet was continued throughout the study. Lipid profile variables, safety indicators, adverse events (AEs, and compliance with study medications were assessed. Results: One hundred patients (71 women, 29 men; mean [SD] age, 52 [10] years entered the study after the dietary run-in period. After 8 weeks of treatment, the mean (SD serum LDL-C level decreased significantly in the policosanol group (P<0.001 vs baseline and placebo from 3.57 (0.30 mmol/L to 2.86 (0.41 mmol/L (change, −19.9%. Significantly more patients in the policosanol group (42 patients [84%] achieved a ≥15% decrease in serum LDL-C than in the placebo group (2 patients [4%] (P<0.001. Also in the policosanol group, the mean (SD serum TC level decreased significantly, from 5.20 (0.22 mmol/L to 4.56 (0.44 mmol/L (P<0.001 vs baseline and placebo (change, −12.3%; the mean (SD triglyceride (TG

    To measure serum leptin levels and compare them in lean and obese subjects and to identify correlation between serum leptin levels, heart rate and hypertension in lean and obese subjects among adult females. Seventy female subjects with different body mass indices were selected from OPD of Jinnah Medical and Dental College Hospital (OPD), Karachi. Heart rate was counted manually; blood pressure was measured by mercury sphygmomanometer while serum leptin was measured using enzyme-linked immunoassay. The outcomes hypertension and heart rate were correlated to risk factor leptin. Mean heart rate, systolic and diastolic blood pressure and serum leptin levels of obese people were 90+-1, 142+-2, 89+-1 and 24.13+-1.7 respectively, which were significantly higher as compared to lean subjects (p<0.05). All the parameters correlated positively and significantly with increasing BMI. There was a relationship of tachycardia and hypertension with high serum leptin levels in obesity. Serum leptin levels increase with the level of obesity. Hyper-leptinemia is associated with tachycardia and increases in both systolic and diastolic blood pressure in obesity via complex mechanisms.

    To evaluate blood and serum markers in traumatic spinal cord injured (SCI) patients, with and without pressure sores. This cross-sectional study was performed at the Ministry of Health Diskapi Yildirim Beyazit, and Numune Education and Research Hospitals, Ankara, Turkey, from 2006-2008. A total of 23 SCI patients with pressure sores (group I) and a control group of 25 SCI patients without pressure sores (group II) were evaluated. Characteristics of sores were examined with respect to duration, location, grade, tissue types, surface area, and exudate amount. Recorded laboratory parameters included erythrocyte sedimentation rates (ESR), C-reactive protein (CRP), hemoglobin (Hb), hematocrit (Htc), lymphocytes, white blood cells (WBC), red blood cells (RBC), serum iron, transferrin, total iron-binding capacity (TIBC), ferritin, total protein, albumin, vitamin B12, and zinc. The most common pressure sore location was the sacrum (38%). Compared to the control group, the patients with pressure sores showed anemia with reduced serum iron, transferrin, TIBC, and increased ferritin. They also had increased ESR, CRP, and WBC and reduced lymphocytes, total protein, albumin and zinc. Statistically significant correlations were found between CRP, Hb, Htc, lymphocytes, RBC, WBC, and serum protein levels, and grade of pressure sores. Clinicians should regularly screen patients with respect to blood and serum markers, in order to determine any risks for pressure sores, and they should perform immediate preventive measures based on the patient's condition.

    Full Text Available The aim of this work was to study the proteolytic activity of IgGs purified from blood serum of Wistar rats at experimental rheumatoid arthritis (ERA induced by an injection of bovine collagen of type II. Twenty rats were immunized with a preparation of bovine collagen II (Sigma-Aldrich, USA in the presence of complete Freund’s adjuvant. ERA development was determined by inflammation in limbs of treated animals. IgG preparations were isolated from blood serum of immunized and non-immunized animals by precipitation of antibodies with 33% ammonium sulfate followed by chromatography on the Protein G-Sepharose column. Human histone H1, bovine collagen II, calf thymus histones, myelin basic protein (MBP, bovine serum albumin (BSA, and bovine casein were used as substrates of the proteolytic activity of IgGs. It was found that IgG preparations from blood serum of rats with ERA were capable of cleaving histone H1 and MBP, however, they were catalytically inactive towards collagen II, casein, BSA, and core histones. IgGs from blood serum of non-immunized rats were proteolytically inactive towards all used protein substrates. Thus, we demonstrated that immunization of rats with bovine collagen II induced IgG-antibodies possessing the proteolytic activity towards histone H1 and MBP. This activity might be associated with the development of inflammatory processes in the immunized rats.

  10. The Canadian experience: why Canada decided against an upper limit for cholesterol.

    Canada, like the United States, held a "consensus conference on cholesterol" in 1988. Although the final report of the consensus panel recommended that total dietary fat not exceed 30 percent and saturated fat not exceed 10 percent of total energy intake, it did not specify an upper limit for dietary cholesterol. Similarly, the 1990, Health Canada publication "Nutrition Recommendations: The Report of the Scientific Review Committee" specified upper limits for total and saturated fat in the diet but did not specify an upper limit for cholesterol. Canada's Guidelines for Healthy Eating, a companion publication from Health Canada, suggested that Canadians "choose low-fat dairy products, lean meats, and foods prepared with little or no fat" while enjoying "a variety of foods." Many factors contributed to this position but a primary element was the belief that total dietary fat and saturated fat were primary dietary determinants of serum total and low-density lipoprotein (LDL) cholesterol levels, not dietary cholesterol. Hence, Canadian health authorities focused on reducing saturated fat and trans fats in the Canadian diet to help lower blood cholesterol levels rather than focusing on limiting dietary cholesterol. In an effort to allay consumer concern with the premise that blood cholesterol level is linked to dietary cholesterol, organizations such as the Canadian Egg Marketing Agency (CEMA) reminded health professionals, including registered dietitians, family physicians and nutrition educators, of the extensive data showing that there is little relationship between dietary cholesterol intake and cardiovascular mortality. In addition, it was pointed out that for most healthy individuals, endogenous synthesis of cholesterol by the liver adjusts to the level of dietary cholesterol intake. Educating health professionals about the relatively weak association between dietary cholesterol and the relatively strong association between serum cholesterol and saturated fat and

    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.

    Dyslipidemia, particularly the elevated serum cholesterol levels, aggravate the pathophysiology of type 2 diabetes. In the present study we explored the relationship between fasting blood sugar and serum lipid parameters in human volunteers which revealed a significant linear effect of serum cholesterol on fasting blood glucose. Short term feeding of cholesterol enriched diet to rodent model resulted in elevated serum cholesterol levels, cholesterol accumulation in pancreatic islets and hyperinsulinemia with modest increase in plasma glucose level. To explore the mechanism, we treated cultured BRIN-BD11 pancreatic beta cells with soluble cholesterol. Our data shows that cholesterol treatment of cultured pancreatic beta cells enhances total cellular cholesterol. While one hour cholesterol exposure enhances insulin exocytosis, overnight cholesterol accumulation in cultured pancreatic beta cells affects cellular respiration, and inhibits Glucose stimulated insulin secretion. We further report that (E)-4-Chloro-2-(1-(2-(2,4,6-trichlorophenyl) hydrazono) ethyl) phenol (small molecule M1) prevents the cholesterol mediated blunting of cellular respiration and potentiates Glucose stimulated insulin secretion which was abolished in pancreatic beta cells on cholesterol accumulation.

E-mail: samira.veterinaria@gmail.com International researchers presented results indicating frequent involvement of Mycoplasma spp. as a causative agent of mastitis in cattle, associating its presence with significant economic losses to farmers. Mycoplasma bovis is the species most reported and relevant, because it causes more severe disease. The level of antibodies against M. bovis remains high for several months and can be detected by ELISA. The aim of this work was to develop an indirect ELISA with whole cell antigen of M. bovis (strain Donetta PG 45 with subsequent application in bovine blood serum samples for detection of antibodies against M. bovis. The immunization of cows A and B by inoculating an immunogen against M. bovis to obtain hyperimmune blood serum was the first stage of this work, then the stage of standardization of ELISA was proceeded. The concentration of 2 mg of antigen/mL for coating the microtiter plates was decided by statistical analyses. The optical density value 0,2 was determined as the limit of reactivity discrimination of samples (the cut-off point. The hyperimmune blood serum sample of the cow A (collected 30 days after immunization was chosen as the positive control and, the fetal calf serum was chosen as negative control of the assay. In addition, the ideal optimal dilutions found for blood serum samples was 1:400 and for conjugate was 1:10.000 and the substrate used was the ortho

    No large-scale, longitudinal studies have examined the combined effects of blood pressure (BP) and total cholesterol levels on long-term risks for subtypes of cardiovascular death in an Asian population. To investigate these relationships, a meta-analysis of individual participant data, which included 73 916 Japanese subjects (age, 57.7 years; men, 41.1%) from 11 cohorts, was conducted. During a mean follow-up of 15.0 years, deaths from coronary heart disease, ischemic stroke, and intraparenchymal hemorrhage occurred in 770, 724, and 345 cases, respectively. Cohort-stratified Cox proportional hazard models were used. After stratifying the participants by 4 systolic BP ×4 total cholesterol categories, the group with systolic BP ≥160 mm Hg with total cholesterol ≥5.7 mmol/L had the greatest risk for coronary heart disease death (adjusted hazard ratio, 4.39; Pdeath, and total cholesterol was inversely associated with intraparenchymal hemorrhage, but no significant interactions between BP and total cholesterol were observed for stroke. High BP and high total cholesterol can synergistically increase the risk for coronary heart disease death but not for stroke in the Asian population. © 2015 American Heart Association, Inc.

    Diabetes mellitus is a major risk factor for cardiovascular disease. However, the excess risk of death may vary substantially in subgroups of patients with type 2 diabetes, being highest in those younger than 55 years of age. A HbA1c value of 7.0 % or less is recommended for most patients with type 2 diabetes to reduce the incidence of microvascular disease, although individualized approaches that balance the benefits of glycemic control against the harms of hypoglycemia are encouraged. The selection of antidiabetic medications is of paramount importance, as the drug should not aggravate, and ideally even improve cardiovascular risk factors, with the hope to reduce cardiovascular morbidity and mortality. Patients with diabetes mellitus between 40 and 75 years of age with LDL-C between 70 and 189 mg/dL should be treated with a moderate-intensity statin. Implicit in this recommendation is the aim to reduce further LDL-C level in diabetes, in order to improve the cardiovascular outlook. The new PCSK9 inhibitors (evolocumab and arilocumab) are very promising, but, at present, their cost-effectiveness ratios exceed commonly accepted thresholds. For many people with diabetes mellitus and hypertension blood pressure should be blood pressure target for all patients with type 2 diabetes mellitus. Ultimately, in the face of uncertainty in medicine, the final decision regarding a specific patient is best left to the clinician.

    Uric acid is an end product of purine degradation in humans and primarily excreted through urine. In adulthood, concentrations rise steadily over time and vary with height, body weight, blood pressure, renal function, and alcohol intake. Uric acid is known as anti-oxidant, it has a beneficial role in diseases. Elevated serum uric acid associated with anincreased risk of cardiovascular disease. It has been found that elevated levels of uric acid associated with high risks of acomplication of type 2 diabetes mellitus and It has astrong association between elevated uric acid levels and obesity, metabolic syndrome, diabetes mellitus, hypertension, cardiovascular and renal disorders. The aim of the study analyzed the association between serum uric acid level and blood pressure in type 2 diabetes mellitus patients. This research is descriptive analytic research with a cross sectional design included 50 diabetic subjects aged over 40 years old. Subjects picked by consecutive sampling then we examined the weight, height, waist size, blood pressure, fasting blood sugar, and serum uric acid level. Statistical analysis using chi-square found that there was no significant association between serum uric acid level and systole and diastole pressure in type 2 diabetes mellitus patients (p>0.005).

    The effects of acidic polysaccharides purified from Gastrodia rhizome on blood pressure and serum lipid levels in spontaneously hypertensive rats (SHR) fed a high-fat diet were investigated. Acidic polysaccharides were purified from crude polysaccharides by DEAE-Sepharose CL-6B. Thirty-six male SHR were randomly divided into three groups: Gastrodia rhizome crude polysaccharide (A), acidic polysaccharide (B) groups, and a control group (C). A 5-week oral administration of all treatment groups was performed daily in 3- to 8-week-old SHRs with a dose of 6 mg/kg of body weight/day. After 5 weeks of treatment, total cholesterol in the acidic polysaccharide group, at 69.7 ± 10.6 mg/dL, was lower than in the crude polysaccharide group (75.0 ± 6.0 mg/dL) and the control group (89.2 ± 7.4 mg/dL). In addition, triglyceride and low-density lipoprotein cholesterol levels in the acidic polysaccharide group were lower than in the crude polysaccharide and control groups. The atherogenic index of the acidic polysaccharide group was 46.3% lower than in the control group. Initial blood pressure after the initial three weeks on the high-fat diet averaged 195.9 ± 3.3 mmHg among all rats. Compared with the initial blood pressure, the final blood pressure in the control group was increased by 22.8 mmHg, whereas it decreased in the acidic polysaccharide group by 14.9 mmHg. These results indicate that acidic polysaccharides from Gastrodia rhizome reduce hypertension and improve serum lipid levels. PMID:22312280

    Background and Objectives. There is no data analyzing the outcome of blood transfusions and oral iron therapy in patients with kidneys failure in sub-Saharan Africa. The present study aimed to fill that gap and assess the value of ferritin in the diagnosis of iron overload and deficiency. Design. From January to February 2012, we prospectively studied 85 hemodialysis patients (78% of males and 22% of females aged 20 to 79 years) attending the Gabonese National Hemodialysis Centre. Results. Correlation studies showed (a) a strong positive linear relationship between the number of blood transfusions and high serum ferritin in hemodialysis patient (Spearman r : 0.74; P value: 0.0001); (b) a weak association between the number of blood transfusions and serum iron concentrations (Spearman r : 0.32; P value: 0.04); (c) a weak association between serum ferritin and serum iron (Spearman r : 0.32; P value: 0.003). Also, the strength of agreement beyond chance between the levels of ferritin and iron in the serum was poor (κ = 0.14). The prevalence of iron overload was 10.6%, whereas the prevalence of iron deficiency was 2.3%, comparing (1) patients with a maximum of one transfusion not on iron therapy; (2) patients with a maximum of one transfusion on iron therapy; (3) polytransfused patients not on iron therapy; and (4) polytransfused patients on oral iron therapy. The “Kruskal-Wallis test” showed that ferritin levels varied significantly between the groups (P value: 0.0001). Conclusion. Serum ferritin is not reliable as a marker of iron overload. For patients undergoing regular transfusion we recommend routine serum ferritin measurement and yearly measurement of LIC. PMID:25685597

    At the ABCC clinic in Hiroshima 1330 subjects were investigated as to serum pepsin levels over a four month period. The normal mean values compared well with those reported for a United States population using a similar technique. There appeared to be no significant change in serum pepsin level with age, and no difference could be detected among individuals of the ABO blood groups. No relationship was found between serum pepsin level and exposure to ionizing radiation. Patients with gastric and duodenal ulcers had mean levels which were higher than normal mean values, while patients with leukemia had lower than normal mean levels. Patients with gastric polyps and gastric cancer had normal mean values. It is believed that the relation of serum pepsin activity to cancer of the stomach is not settled and deserves further investigation. 23 references, 2 figures, 4 tables.

    Vitamin B12 (cobalamin and its derivatives) deficiency has been identified as a potential modifiable risk factor for dementia and Alzheimer's disease. Chronic deficiency of vitamin B12 has been significantly associated with an increased risk of cognitive decline. An effective and efficient method for measuring vitamin B12 concentration in human blood would enable ongoing tracking and assessment of this potential modifiable risk factor. In this work we present an optical sensor based on resonance Raman spectroscopy for rapid measurements of vitamin B12 in human blood serum. The measurement takes less than a minute and requires minimum preparation (centrifuging) of the collected blood samples.

    With the rising trend of obesity among the general population, it is also important to assess the obesity and health status among military population. The aim of this study was to determine the prevalence of overweight and obesity among Malaysian Army (MA) personnel as well as the relationship between selected socio-demographics factors, antropometric profiles, body composition and random blood test value. A cross sectional study involving 378 male military personnel aged between 20 to 48 years old was conducted at two MA bases in Kuala Lumpur between November and December 2012. Antropometric measurements included height, weight and waist circumference (WC). Body fat percentage was measured using bioelectrical impedance analysis method (Tanita TBF-300A). Mean height, weight, BMI, WC, body fat percentage, age, monthly income and duration of service were 1.71 ± 0.6 m, 71.7 ± 12.2 kg, 24.6 ± 4.1 kg/m{sup 2}, 87.0 ± 10.0 cm, 23.4 ± 6.6%, 29.1 ± 5.5 years, RM 2115.12 ± 860.70 and 9.9 ± 5.6 years respectively. According to WHO (1998) classification of BMI, 3.2% of the subjects were underweight, 54.8% normal, 32.8% overweight and 9.3% obese. It was obeserved that 40.2% of the subjects had waist circumference value of 90 cm or more and were considered high risk for diebetes and cardiovascular diseases. This study found that BMI was highly correlated with weight (r=0.925, p<0.05), WC (r=0.852, p<0.05) and body fat percentage. Body fat percentage also show high correlation with weight (r=0.759, p<0.05) and WC (r=0.768, p<0.05. The result from 173 of 378 subjects that were selected for random blood test found that 4.6%, 3.5% and 26.0% had diabetes, high cholesterol and high triglyceride respectively. There was a weak correlation between random blood glucose level with weight (r=0.221, p<0.05), BMI (r=0.243, p<0.05), WC (r=0.298, p<0.05), body fat percentage (r=0.163, p<0.05) and age (r=0.223, p<0.05).

    Abstract High blood pressure or hypertension is predicted to increase by 60% in 2025. Women of Reproductive Age (WRA have a higher risk of hypertension caused by a diet of high energy, high protein, and high fat, but low in fiber. Indonesian is composed of various ethnics that have different diets, one of them is Madurese ethnic whose diets are high in cholesterol but low in fiber. This study aims to determine the relationship of cholesterol intake with blood pressure in WRA. This study used a cross sectional study and purposive sampling technique (n=48. The result showed 93.8% of cholesterol intake is in accordance with the WHO recommendation that is ≤300 mg. Based on statistic test, cholesterol intake was not related with  respondents blood pressure (p=1.000. This research concludes that there is no relationship between cholesterol intake and blood pressure in WRA with high blood pressure. Further research is needed on the same subjects with more of respondents and laboratory test, if possible, to find out the duration of cholesterol intake that can increase blood cholesterol level.

    Hepatobiliary complications are common during parenteral nutrition. Lipid moiety in commercially available solutions contains plant sterols. It is not known whether plant sterols in parenteral nutrition interfere with hepatic function in adults. We detected how different amounts of plant sterols in parenteral nutrition solution affected serum plant sterol concentrations and liver enzymes during a 1.5-year follow-up in a patient with short bowel syndrome. Serum lipid, plant sterol, and liver enzyme levels were measured regularly during the transition from Intralipid (100% soy-based intravenous fat emulsion) to ClinOleic (an olive oil-based intravenous fat emulsion with 80% olive oil, 20% soy oil and lower plant sterols); the lipid supply was also gradually increased from 20 to 35 g/d. Plant sterols in parenteral nutrition solution and serum were measured with gas-liquid chromatography. During infusion of soy-based intravenous fat emulsion (30 g/d, total plant sterols 87 mg/d), the concentrations of sitosterol, campesterol, and stigmasterol were 4361, 1387, and 378 microg/dL, respectively, and serum liver enzyme values were >or= 2.5 times above upper limit of normal. After changing to olive oil-based intravenous fat emulsion (20-35 g/d, plant sterols 37-65 mg/d), concentrations decreased to 2148 to 2251 microg/dL for sitosterol, 569-297 microg/dL for campesterol, and 95-55 microg/dL for stigmasterol. Concomitantly, liver enzyme values decreased to 1.4 to 1.8 times above upper limit of normal at the end of follow-up. The nutrition status of the patient improved. The amount of plant sterols in lipid emulsion affects serum liver enzyme levels more than the amount of lipid.

    Full Text Available Several epidemiologic studies have reported that exposure to noise is associated with cardiovascular disease. The increased body weight is often associated with metabolic as well as increased blood pressure. The aim of this study is to investigate the correlation between the elevation of blood pressure and serum leptin hormones due to the effects of noise in the work place. A total of 80 volunteer males where included in this study with an age range between of 20 and 45 years, they were divided in two groups equally, the 1 st group were exposed to noise in the workplace while the 2 nd group were not. The individual noise exposure was determined by using a sound level meter. The range of noise was 80-100 dBA. Body Mass Index was also taken for each individual by a standard measure, blood pressure was measured by OMRON sphygmomanometer and serum leptin was measured through venous blood sample analysis enzyme linked immunosorbent assay. Spearman rank order correlation was used to examine the correlations between Blood pressure value (Systolic, Diastolic and Leptin. All the relationships between parameters showed a positive correlation. Systolic and diastolic blood pressure values had a significant correlation to leptin hormone level in comparison to the control. There was a significant relation between leptin and blood pressure. leptin effects on the sympathetic nervous system may provide a partial explanation. Therefore, Leptin might have diverse cardiovascular actions.

    Patients with rheumatoid arthritis (RA) have an increased cardiovascular (CV) risk. This study aimed to analyze the effects of Tofacitinib treatment, a Janus kinase inhibitor, on atherosclerosis in patients with RA. Patients with an active RA (28-joint disease activity score-erythrocyte sedimentation rate > 3.2) despite methotrexate (MTX) treatment 12 mg/week were included in this open-label prospective study and started on Tofacitinib (10 mg/day, 5 mg twice/day). Japanese guideline does not allow high dose of MTX. All patients used a stable dosage of MTX, steroids, and statins or lipid-lowering drugs. The primary endpoint was the comparison of the carotid intima-media thickness (CIMT) at the baseline and 54 weeks after Tofa treatment. Clinical data were collected at regular visits. Forty-six patients completed this study. CIMT did not significantly change from baseline to 54 weeks (1.09 ± 0.69 and 1.08 ± 0.78 mm, p = 0.82). In 12 patients who had atherosclerosis at baseline (carotid intima-media thickness > 1.10 mm), there was a significant decrease in CIMT (0.05± 0.026 mm; p < 0.05). However, the decrease in CIMT was of limited clinical significance. Tofacitinib increased fasting total cholesterol levels from baseline to 54 weeks (216 ± 25.3 and 234 ± 28.8 mg/dL, p < 0.01). Tofacitinib affects atherosclerosis in patients with active RA The CIMT in RA patients was stable. Tofacitinib decreased the CIMT of patients who had increased CIMT at baseline. Tofacitinib reduced RA disease activity and limited vascular damage despite up-regulating cholesterol in patients with an active RA.

    Combining foods with recognized cholesterol-lowering properties (dietary portfolio) has proven highly effective in lowering serum cholesterol under metabolically controlled conditions. To assess the effect of a dietary portfolio administered at 2 levels of intensity on percentage change in low-density lipoprotein cholesterol (LDL-C) among participants following self-selected diets. A parallel-design study of 351 participants with hyperlipidemia from 4 participating academic centers across Canada (Quebec City, Toronto, Winnipeg, and Vancouver) randomized between June 25, 2007, and February 19, 2009, to 1 of 3 treatments lasting 6 months. Participants received dietary advice for 6 months on either a low-saturated fat therapeutic diet (control) or a dietary portfolio, for which counseling was delivered at different frequencies, that emphasized dietary incorporation of plant sterols, soy protein, viscous fibers, and nuts. Routine dietary portfolio involved 2 clinic visits over 6 months and intensive dietary portfolio involved 7 clinic visits over 6 months. Percentage change in serum LDL-C. In the modified intention-to-treat analysis of 345 participants, the overall attrition rate was not significantly different between treatments (18% for intensive dietary portfolio, 23% for routine dietary portfolio, and 26% for control; Fisher exact test, P = .33). The LDL-C reductions from an overall mean of 171 mg/dL (95% confidence interval [CI], 168-174 mg/dL) were -13.8% (95% CI, -17.2% to -10.3%; P portfolio; -13.1% (95% CI, -16.7% to -9.5%; P portfolio; and -3.0% (95% CI, -6.1% to 0.1%; P = .06) or -8 mg/dL (95% CI, -13 to -3 mg/dL; P = .002) for the control diet. Percentage LDL-C reductions for each dietary portfolio were significantly more than the control diet (P portfolio interventions did not differ significantly (P = .66). Among participants randomized to one of the dietary portfolio interventions, percentage reduction in LDL-C on the dietary portfolio was associated

    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.

    Accumulating evidence suggests that S-nitrosothiols (RSNOs) play key roles in human health and disease. To clarify their physiological functions and roles in diseases, it is necessary to promote some new techniques for quantifying RSNOs in blood and other biological fluids. Here, a new method using gold nanoparticle catalysts has been introduced for quantitative evaluation of RSNOs in blood serum. The assay involves degrading RSNOs using gold nanoparticles and detecting nitric oxide (NO) released with NO-selective electrodes. The approach displays very high sensitivity for RSNOs with a low detection limit in the picomolar concentration range (5.08 × 10(-11) mol L(-1), S/N=3) and is free from interference of some endogenous substances such as NO(2)(-) and NO(3)(-) co-existing in blood serum. A linear function of concentration in the range of (5.0-1000.0) × 10(-9) mol L(-1) has been observed with a correlation coefficient of 0.9976. The level of RSNOs in blood serum was successfully determined using the described method above. In addition, a dose-dependent effect of gold nanoparticles on the sensitivity for RSNOs detection is revealed, and thereby the approach is potentially useful to evaluate RSNOs levels in various biological fluids via varying gold nanoparticles concentration.

    The dynamics of 38 biochemical parameters of blood, serum and urine was studied in ten heifers during their oestrous cycle in a light house (80-340 lux) and a dark small house (10-40 lux). In the light stable a significant influence (P less than 0.05) was found to be exerted on five parameters and in the dark stable nine parameters, four being influenced in the same way in both houses: haematocrit value and haemoglobin in blood and cholesterol and progesterone in serum; the relationship of progesterone content in serum to the days of oestrous cycle was particularly high in the light house. The comparison of the parameters between the groups demonstrated a significant (P less than 0.05) influence of light regime, exerted on some days of the oestrous cycle upon the levels of inorganic phosphorus, total protein and aspartate aminotransferase activity (AST) in serum and upon haematocrit, haemoglobin and ketone bodies in the blood of heifers. However, the light regime did not influence the levels of progesterone which were somewhat higher in the light house but with no statistically significant difference from the dark house. A significant difference between the groups was obtained in the levels of sodium and phosphorus in urine (P less than 0.05) between the first and tenth days of the oestrous cycle. No differences in the oestrous cycle between the heifers in the light and dark stables were recorded. Neither was the duration of heat influenced significantly; it was only less manifest in the dark stable.

    With the rising trend of obesity among the general population, it is also important to assess the obesity and health status among military population. The aim of this study was to determine the prevalence of overweight and obesity among Malaysian Army (MA) personnel as well as the relationship between selected socio-demographics factors, antropometric profiles, body composition and random blood test value. A cross sectional study involving 378 male military personnel aged between 20 to 48 years old was conducted at two MA bases in Kuala Lumpur between November and December 2012. Antropometric measurements included height, weight and waist circumference (WC). Body fat percentage was measured using bioelectrical impedance analysis method (Tanita TBF-300A). Mean height, weight, BMI, WC, body fat percentage, age, monthly income and duration of service were 1.71 ± 0.6 m, 71.7 ± 12.2 kg, 24.6 ± 4.1 kg/m2, 87.0 ± 10.0 cm, 23.4 ± 6.6%, 29.1 ± 5.5 years, RM 2115.12 ± 860.70 and 9.9 ± 5.6 years respectively. According to WHO (1998) classification of BMI, 3.2% of the subjects were underweight, 54.8% normal, 32.8% overweight and 9.3% obese. It was obeserved that 40.2% of the subjects had waist circumference value of 90 cm or more and were considered high risk for diebetes and cardiovascular diseases. This study found that BMI was highly correlated with weight (r=0.925, pselected for random blood test found that 4.6%, 3.5% and 26.0% had diabetes, high cholesterol and high triglyceride respectively. There was a weak correlation between random blood glucose level with weight (r=0.221, pattention to the existence of overweight and obesity as well as the risk of non-communicable diseases among military population. Therefore, future intervention from the aspect of nutritional education and health awareness can benefit thus optimizing the health status of MA military personnel.

    Recent studies suggest that high levels of serum uric acid of very early life are a result of the in-utero environment and may lead to elevated blood pressure (BP) in adulthood. However, serum uric acid levels can change throughout life. We investigated the effect of serum uric acid levels in childhood on the BP tracking and analysed BP according to changes in serum uric acid levels in early life. A total of 449 children from the Ewha Birth and Growth Cohort study underwent at least 2 follow-up examinations. Data were collected across 3 check-up cycles. Serum uric acid levels, BP, and anthropometric characteristics were assessed at 3, 5, and 7 years of age. Children with a serum uric acid level higher than the median values had significantly increased systolic BP (SBP) and diastolic BP at 3 years of age. Baseline serum uric acid levels measured at 3 years of age, significantly affected subsequent BP in the sex and body mass index adjusted longitudinal data analysis (P uric acid over time, subjects with high uric acid levels at both 3 and 5 years of age had the highest SBP at 7 years of age. These findings suggest the importance of maintaining an adequate level of serum uric acids from the early life. Appropriate monitoring and intervention of uric acid levels in a high-risk group can reduce the risk of a future increased BP. © American Journal of Hypertension, Ltd 2017. All rights reserved.

    Full Text Available The intestinal microbial communities play critical roles in various aspects of body function of the host. Prebiotics, such as dietary fiber, can affect health of the host by altering the composition of intestinal microbiota. Although brown seaweed Laminaria japonica is rich in dietary fiber, studies on its prebiotic potential are quite rare. In this study, basal diet (control, basal diet supplemented with dried L. japonica (DLJ, heat-treated dried L. japonica (HLJ, or heated dried L. japonica with added fructooligosaccharide (FHLJ was fed to rats for 16 weeks. Serum concentrations of IgG, triglyceride, and cholesterol were measured. In addition, the intestinal microbiota composition was analyzed by high-throughput sequencing of 16S rRNA gene. As compared to the control group, DLJ, HLJ, and FHLJ groups showed significantly higher serum IgG concentration, but had lower weight gain and serum triglyceride concentration. Moreover, DLJ, HLJ, and FHLJ groups showed lower Fimicutes to Bacteroidetes ratio when compared with the control group. As compared with the control group, obesity-associated bacterial genera (Allobaculum, Turicibacter, Coprobacillus, Mollicute, and Oscilibacter, and the genera with pathogenic potentials (Mollicute, Bacteroides, Clostridium, Escherichia, and Prevotella decreased while leanness-associated genera (Alistipes, Bacteroides, and Prevotella, and lactic acid bacterial genera (Subdoligranulum, Streptococcus, Lactobacillus, Enterococcus, and Bifidobacterium increased in all treatment groups. On the contrary, butyric acid producing genera including Subdoligranulum, Roseburia, Eubacterium, Butyrivibrio, and Anaerotruncus increased significantly only in FHLJ group. The overall results support multiple prebiotic effects of seaweed L. japonica on rats as determined by body weight reduction, enhanced immune response, and desirable changes in intestinal microbiota composition, suggesting the great potential of L. japonica as an

    Seventeen-day-old Nile tilapia fry were fed a standard diet (C) or diets containing 50-700 mg kg(-1) Quillaja saponin (QS) extract (groups S50, S150, S300, S500 and S700). After the first 8 weeks, 30 randomly selected tilapia from each of the treatments were placed in separate aquaria and fed the standard diet without saponins from then on (these were designated S50/C, S150/C, S300/C, S500/C and S700/C). The fish grew from an initial average weight of approximately 30 mg to a final average weight of 79 g during the 6-month feeding period. The difference between the average weight of C-fed tilapia and the treatment with the highest average weight after 6 months was 53.5%. The sex ratio of tilapia in the saponin-fed groups deviated from the normal 50:50 male:female ratio, with the S700 group showing a significantly higher number of males. Quillaja saponin stimulated LH release from dispersed tilapia pituitary cells in vitro. This effect was abolished in the presence of dilute calf serum. Serum LH values did not show any diet-dependent trend in either male or female tilapia in vivo. In both continuously saponin-fed and only-initially saponin-fed groups, the average serum (but not muscle) cholesterol levels in males showed an increasing trend (R(2) values of 0.62 and 0.69) with increasing dietary saponin level. It was concluded that dietary QS has the potential to change the sex-ratio in favour of males. More investigations are required to determine the mechanism of action and the optimum dietary level of QS for maximum effects.

    The paper presents the results of a health screening programme conducted in 10 major centers in Malaysia--Kuala Lumpur, Penang, Ipoh, Johor Bahru, Alor Star, Kuala Terengganu, Malacca, Kota Bahru, Kuching and Kota Kinabalu during the National Heart Weeks, 1995-1997. There were 6,858 participants of both sexes aged between 6 years to 81 years old. The parameters involved in the screening programme were body mass index, blood pressure, heart rate, cholesterol and glucose. The following are the results of the study:- 1. The mean and standard deviation for the body mass index (BMI), systolic blood pressure (SBP), diastolic blood pressure (DBP), heart rate (HR), total cholesterol (TC) and non fasting (random) blood glucose (GL) of the volunteers studied were 24.3 +/- 4.0 kg/m2, 128.3 +/- 21.1 mmHg, 79.6 +/- 11.9 mmHg, 77.2 +/- 12.1 bpm, 5.33 +/- 1.37 mmol/l and 5.11 +/- 1.97 mmol/l respectively. 2. There was a rising trend for BMI, SBP, DBP, TC and GL with age. The HR was higher in the younger age group of those below 20 years. Males tended to have higher mean values than females except for HR which was similar in both sexes. 3. The Malays, Chinese and Indians seemed to have closely similar mean values for SBP, DBP and HR but the Indians possessed the highest BMI (25.62 +/- 3.90 kg/m2), TC (5.61 +/- 1.48 mmol/l) and GL (5.41 +/- 2.43 mmol/l) among the three major ethnic groups. While the Ibans had highest TC (6.07 + 1.09 mmol/l), their GL level was the lowest (4.76 +/- 1.15 mmol/l). The Kadazans had the lowest TC level (4.94 +/- 1.39 mmol/l) among all the ethnic groups. 4. Among the participants screened, 31.9% were overweight (BMI > or = 25), 7.6% were obese (BMI > or = 30); 26.8% had raised SBP (> or = 140 mmHg) and 19.3% had raised DBP (> or = 90 mmHg); 13.6% of the participants had increased HR (> or = 90 bpm), 22% had raised TC (> or = 6.20 mmol/l) and 2% had raised GL (> or = 11.00 mmol/l). There was a higher prevalence for abnormal values with increasing age

    Full Text Available The recent thriving development of biobanks and associated high-throughput phenotyping studies requires the elaboration of large-scale approaches for monitoring biological sample quality and compliance with standard protocols. We present a metabolomic investigation of human blood samples that delineates pitfalls and guidelines for the collection, storage and handling procedures for serum and plasma. A series of eight pre-processing technical parameters is systematically investigated along variable ranges commonly encountered across clinical studies. While metabolic fingerprints, as assessed by nuclear magnetic resonance, are not significantly affected by altered centrifugation parameters or delays between sample pre-processing (blood centrifugation and storage, our metabolomic investigation highlights that both the delay and storage temperature between blood draw and centrifugation are the primary parameters impacting serum and plasma metabolic profiles. Storing the blood drawn at 4 °C is shown to be a reliable routine to confine variability associated with idle time prior to sample pre-processing. Based on their fine sensitivity to pre-analytical parameters and protocol variations, metabolic fingerprints could be exploited as valuable ways to determine compliance with standard procedures and quality assessment of blood samples within large multi-omic clinical and translational cohort studies.

  10. Trophic enrichment factors for blood serum in the European badger (Meles meles.

    Directory of Open Access Journals (Sweden)

    David J Kelly

    Full Text Available Ecologists undertaking stable isotopic analyses of animal diets require trophic enrichment factors (TEFs for the specific animal tissues that they are studying. Such basic data are available for a small number of species, so values from trophically or phylogenetically similar species are often substituted for missing values. By feeding a controlled diet to captive European badgers (Meles meles we determined TEFs for carbon and nitrogen in blood serum. TEFs for nitrogen and carbon in blood serum were +3.0 ± 0.4‰ and +0.4 ± 0.1‰ respectively. The TEFs for serum in badgers are notably different from those published for the red fox (Vulpes vulpes. There is currently no data for TEFs in the serum of other mustelid species. Our data show that species sharing similar niches (red fox do not provide adequate proxy values for TEFs of badgers. Our findings emphasise the importance of having species-specific data when undertaking trophic studies using stable isotope analysis.

    Full text: The albumin, being a basic functional linkage of numerous endogenous and exogenous substances is the most important protein of blood plasma. At the diseases connected to liver disfunction, collected in blood metabolite reduce connecting ability of albumino. The aim of the present research was a development of radiochemical method of determination of ability of albumin to bind the tritium labeled preparation drotaverine hydrochloride (no - spa). We had developed a micromethod of definition of connecting ability of albumin, allowing to analyse 20 mkl of blood serum. The method consists in incubation of tritium labeled drotaverine hydrochloride with blood serum in vitro, the following fractionation of serum proteins by gel - filtration on a microcolumn with Sephadex G-25, and direct measurement of the radioactivity connected to fraction of proteins of blood serum. The method has been tested on a series of blood serum of control group of healthy people and on a series of blood serum of patients with hepatitis B. We received quantitative characteristics of binding of drotaverine hydrochloride with albumin of patients with hepatitis B. It was preliminary established that binding ability of serum albumin of children with various forms of acute virus hepatitis tends to decrease in comparison with group of the control. Advantage of the developed radiochemical method is high precision and the high sensitivity of detection of infringement of binding ability of albumin. Application of tritium labeled drotaverine hydrochloride allows to measure directly levels of binding of a preparation with albumin

    Full Text Available The human body is constantly under attack from free radicals that occur as part of normal cell metabolism, and by exposure to environmental factors such as UV light, cigarette smoke, environmental pollutants and gamma radiation. The resulting “Reactive Oxygen Species” (ROS circulate freely in the body with access to all organs and tissues, which can have serious repercussions throughout the body. The body possesses a number of mechanisms both to control the production of ROS and to cope with free radicals in order to limit or repair damage to tissues. Overproduction of ROS or insufficient defense mechanisms leads to a dangerous disbalance in the organism. Thereby several pathomechanisms implicated in over 100 human diseases, e.g., cardiovascular disease, cancer, diabetes mellitus, physiological disease, aging, etc., can be induced. Thus, a detailed investigation on the quantity of oxygen radicals, such as hydroxyl radicals (OH● in human serum blood, and its possible correlation with antioxidant therapy effects, is highly topical. The subject of this study was the influence of schizophrenia on the amount of OH● in human serum blood. The radicals were detected by fluorimetry, using terephthalic acid as a chemical trap. For all experiments the serum blood of healthy people was used as a control group.

    Administration of L-arginine has been shown to control ischemic injury by producing nitric oxide which dilates the vessels and thus maintains proper blood flow to the myocardium. In the present study attempt has been made to determine whether oral administration of L-arginine has any effect on oxidant/antioxidant homeostasis in ischemic myocardial patients [represented by the patients of acute angina (AA) and acute myocardial infarction (MI)]. L-arginine has antioxidant and antiapoptotic properties, decreases endothelin-1 expression and improves endothelial function, thereby controlling oxidative injury caused during myocardial ischemic syndrome. Effect of L-arginine administration on the status of free radical scavenging enzymes, pro-oxidant enzyme and antioxidants viz. total thiols, carbonyl content and plasma ascorbic acid levels in the patients has been evaluated. We have observed that L-arginine administration (three grams per day for 15 days) resulted in increased activity of free radical scavenging enzyme superoxide dismutase (SOD) and increase in the levels of total thiols (T-SH) and ascorbic acid with concomitant decrease in lipid per-oxidation, carbonyl content, serum cholesterol and the activity of proxidant enzyme, xanthine oxidase (XO). These findings suggest that the supplementation of L-arginine along with regular therapy may be beneficial to the patients of ischemic myocardial syndromes. PMID:20716909

    Full Text Available AbstractAim: Substance abuse has become a universal crisisin our modern age. Among illegal substances, opium and its derivatives have been ranked second in terms of usage after cannabis in the world. In many Asian regions, the use of opium enjoys a high social acceptance; hence, some common people and even medical practitioners believe that opium lowers blood glucose and pressure and treat dyslipidemia. How much this belief is scientifically justified? Method: The results of available studies on both humans and animals searched in different search engines up to mid-2016 were integrated (77 articles. Upon the findings we try to offer a more transparent picture of the effects of opium on the mentioned factors along with the probable underlying mechanisms of its action. Results: Taken together, a variety of evidences suggest that the consumption of opium has no scientific justification for amendment of these biochemical variables. The mechanisms proposed so far for the action of opium in the three above disorders are summarized at the end of the article. Short term effects seems to be mostly mediated through central nervous system (neural and hormonal mechanisms, but long term effects are often due to the structural and functional alterations in some body organs. Conclusion: Although opium may temporarily reduce blood pressure, but it increases blood glucose and most of blood lipids. Moreover its long term use has negative impacts and thus it aggravates diabetes, dyslipidemia and hypertension. Accordingly, it is necessary to inform societies about the potential disadvantages of unauthorized opium consumption.

    Paradontopathy and neoplasms of the oral cavity represent one of the greatest challenges in human and animal dentistry. EGF plays a key role in maintaining the integrity and proper rate of cell proliferation in normal oral epithelium. The aim of the present study was to study serum levels of EGF in dogs diagnosed with periodontal diseases and oral cavity tumours. The samples comprised of cancerous tissue sections and serum obtained from dogs of various breeds, aged between 5-13 years. Serum EGF concentrations were measured by an immunoenzymatic method. The median for EGF concentration in serum of dogs suffered from severe periodontal diseases was greater when compared to the control group. EGF concentration in dogs with malignant tumours was significantly higher than in those with non-malignant growths. A positive correlation between EGF concentration and tumour size was also observed. EGF level in dogs diagnosed with benign tumours was comparable to the control group. The blood serum level of EGF increases significantly in patients with malignant oral tumours and advanced periodontal disease. In malignant tumours, the high level of EGF correlates with the size and invasiveness of the neoplasm. Copyright© 2018, International Institute of Anticancer Research (Dr. George J.

    Full Text Available Since the end of the last century an upward trend regarding hormone-dependent tumours of the reproductive system, including endometrial cancer (EC has been observed, with one of the trend reasons being increased number of mutations, in particular, microsatellite instability (MSI – the consequence of unpaired nucleotides repair system gene inactivation (MSH2, MSH3, MSH6, MLH1,PMS2, EXO1. This molecular genetic phenomenon may also be characteristic of certain colon cancer forms, while being detectable not only in the tumour but also in blood, which may be of clinical interest as regards either determining risk groups in terms of other localization malignant tumours development, especially colon cancer, or early diagnostics of the said diseases. However, relationship between clinical, phenotypic and molecular risk factors for EC and colon cancer needs further studying. The aim of research – to estimate MSI frequency in blood serum and colonic mucosal lining in patients with EC. Materials and methods. 342 patients with I – IV stage EC aged between 30 and 80 underwent MSI determining in tumour tissue, blood serum and colonic mucosa by means of polymerase chain reaction method using primers for microsatellite sequence (ВАТ-25, ВАТ-26. Colonic mucosal lining samples were obtained by colonoscopy prior to surgical intervention. Genomic DNA purification from blood serum was performed using DNA purification kit produced by Silex M Scientific and Production Company (Russia, in accordance with manufacturer's instructions.

    The blood-brain barrier (BBB), which prevents the entry into the central nervous system (CNS) of most water-soluble molecules over 500 Da, is often disrupted after trauma. Post-traumatic BBB disruption may have important implications for prognosis and therapy. Assessment of BBB status is not routine in clinical practice because available techniques are invasive. The gold-standard measure, the cerebrospinal fluide (CSF)-serum albumin quotient (Q(A)), requires the measurement of albumin in CSF and serum collected contemporaneously. Accurate, less invasive techniques are necessary. The objective of this study was to evaluate the relationship between Q(A) and serum concentrations of monomeric transthyretin (TTR) or S100B. Nine subjects with severe traumatic brain injury (TBI; Glasgow Coma Scale [GCS] score < or =8) and 11 subjects with non-traumatic headache who had CSF collected by ventriculostomy or lumbar puncture (LP) were enrolled. Serum and CSF were collected at the time of LP for headache subjects and at 12, 24, and 48 h after ventriculostomy for TBI subjects. The Q(A) was calculated for all time points at which paired CSF and serum samples were available. Serum S100B and TTR levels were also measured. Pearson's correlation coefficient and area under the receiver operating characteristic (ROC) curve were used to determine the relationship between the serum proteins and QA. Seven TBI subjects had abnormal Q(A)'s indicating BBB dysfunction. The remaining TBI and control subjects had normal BBB function. No significant relationship between TTR and QA was found. A statistically significant linear correlation between serum S100B and Q(A) was present (r = 0.432, p = 0.02). ROC analysis demonstrated a significant relationship between Q(A) and serum S100B concentrations at 12 h after TBI (AUC = 0.800; SE 0.147, 95% CI 0.511-1.089). Using an S100B concentration cutoff of 0.027 ng=ml, specificity for abnormal Q(A) was 90% or higher at each time point. We conclude that

    Since the impact of vitamin D on red blood cell formation has not been well studied, we aimed at assessing the putative link between serum 25-hydroxyvitamin D (25[OH]D) concentrations and hematological markers of erythropoiesis in a large cohort of German adolescents aged 11 to 17 years. In total, 5066 participants from the population-based, nationally representative KiGGS study (Kinder- und Jugendgesundheitssurvey, German Health Interview and Examination Survey for Children and Adolescents) were grouped into either tertiles or clinically accepted cutoff levels for serum 25(OH)D. Results demonstrated significant and inverse correlations between 25(OH)D levels and several hematological parameters including hemoglobin concentration (r = - 0.04, p = 0.003), mean corpuscular hemoglobin (r = - 0.11, p < 0.001), red blood cell count (r = - 0.04, p = 0.002), and soluble transferrin receptor (r = - 0.1, p < 0.001), whereas, in contrast, serum 25(OH)D was positively correlated to the mean corpuscular volume of erythrocytes (r = 0.08, p < 0.001). Multinomial regression models adjusted for clinically relevant confounders confirmed statistically significant differences between the two strata of 25(OH)D groups with respect to red blood cell markers (hemoglobin concentration, red blood cell count, mean corpuscular volume, and corpuscular hemoglobin, as well as iron and soluble transferrin receptor). The link between serum 25(OH)D and several important hematological parameters may point to an inhibitory role of vitamin D in the regulation of erythropoiesis in adolescents. What is Known: • The physiological effects of vitamin D on calcium homeostasis and bone metabolism have been established. • However, much less is known about the impact of circulating vitamin D on erythropoiesis. What is New: • Data from the KiGGS study in German adolescents demonstrated significant associations between serum vitamin D concentrations and red

    Plant sterol (PS)-supplemented foods are recommended to help in lowering serum LDL-cholesterol (LDL-C). Few studies have examined the efficacy of PS-enriched skimmed milk (SM) or semi-SM enriched with vegetable fat (PS-VFM). There is also insufficient information on factors predictive of LDL-C responses to PS. We examined the effects of PS-SM (0·1 % dairy fat) and PS-VFM (0·1 % dairy fat plus 1·5 % vegetable fat) on serum lipids and non-cholesterol sterols in hypercholesterolaemic individuals. In a placebo-controlled, crossover study, forty-three subjects with LDL-C>1300 mg/l were randomly assigned to three 4-week treatment periods: control SM, PS-SM and PS-VFM, with 500 ml milk with or without 3·4 g PS esters (2 g free PS). Serum concentrations of lipids and non-cholesterol sterols were measured. Compared to control, LDL-C decreased by 8·0 and 7·4 % (P synthesis and high cholesterol absorption predicted improved LDL-C responses to PS.

    The quantification of alpha-foetoprotein in dry blood spots from pregnant women was evaluated, using a conventional radioimmunoassay (RIA) with a monospecific antibody. The stability of alpha-foetoprotein in dry blood spots on filter paper was evaluated with respect to mailing, distances travelled, and the existence of high summer temperatures in our region. The results obtained show that the blood alpha-foetoprotein is stable on dry filter spots sent by mail and is stable for up to four weeks at 4, 25 and 37 degrees C. The analytical method used has a minimal detectable concentration of 10 +/- 1.9 international kilo-units/l. Both inter- and intra-assay variabilities are smaller than 10% and this method can provide results comparable with those of conventional serum assays. Results from dry blood spots and serum samples (the latter analysed by both RIA and two-site enzyme immunoassay) exhibited a good correlation (r = 0.98 and r = 0.97, p less than 0.001). The design of the assay and the nature of the samples make this method suitable for a screening programmes for the antenatal detection of open neural tube defects.

    We sought to develop a practical, reproducible and clinically translatable method of radiolabeling serum albumins with fluorine-18 for use as a PET blood pool imaging agent in animals and man. Fluorine-18 radiolabeled fluoronicotinic acid-2,3,5,6-tetrafluorophenyl ester, [ 18 F]F-Py-TFP was prepared first by the reaction of its quaternary ammonium triflate precursor with [ 18 F]tetrabutylammonium fluoride ([ 18 F]TBAF) according to a previously published method for peptides, with minor modifications. The incubation of [ 18 F]F-Py-TFP with rat serum albumin (RSA) in phosphate buffer (pH 9) for 15 min at 37–40 °C produced fluorine-18-radiolabeled RSA and the product was purified using a mini-PD MiniTrap G-25 column. The overall radiochemical yield of the reaction was 18–35% (n = 30, uncorrected) in a 90-min synthesis. This procedure, repeated with human serum albumin (HSA), yielded similar results. Fluorine-18-radiolabeled RSA demonstrated prolonged blood retention (biological half-life of 4.8 hours) in healthy awake rats. The distribution of major organ radioactivity remained relatively unchanged during the 4 hour observation periods either by direct tissue counting or by dynamic PET whole-body imaging except for a gradual accumulation of labeled metabolic products in the bladder. This manual method for synthesizing radiolabeled serum albumins uses fluorine-18, a widely available PET radionuclide, and natural protein available in both pure and recombinant forms which could be scaled up for widespread clinical applications. These preclinical biodistribution and PET imaging results indicate that [ 18 F]RSA is an effective blood pool imaging agent in rats and might, as [ 18 F]HSA, prove similarly useful as a clinical imaging agent

    Niemann-Pick type C disease is an inherited autosomal recessive neurodegenerative disorder characterised by the accumulation of unesterified cholesterol and sphingolipids within the endosomal/lysosomal compartments. It has been observed that the administration of hydroxypropyl-β-cyclodextrin (HPBCD) delays onset of clinical symptoms and reduces accumulation of cholesterol and gangliosides within neuronal cells. It was assumed that HPBCD exerts its action by readily entering the CNS and directly interacting with neurones and other brain cells to facilitate removal of stored cholesterol from the late endosomal/lysosomal compartment. Here, we present evidence that refutes this hypothesis. We use two well established techniques for accurately measuring brain uptake of solutes from blood and show that there is no significant crossing of HPBCD into the brain. The two techniques are brain in situ perfusion and intraperitoneal injection followed by multi-time-point regression analysis. Neither study demonstrates significant, time-dependent uptake of HPBCD in either adult or neonatal mice. However, the volume of distribution available to HPBCD (0.113 ± 0.010 ml/g) exceeds the accepted values for plasma and vascular volume of the brain. In fact, it is nearly three times larger than that for sucrose (0.039 ± 0.006 ml/g). We propose that this indicates cell surface binding of HPBCD to the endothelium of the cerebral vasculature and may provide a mechanism for the mobilisation and clearance of cholesterol from the CNS.

    Full Text Available Background: Cytokines and growth factors were reported to play an important role in stimulating fibroblast proliferation. In vitro culture, fibroblast is mostly culture in medium containing fetal bovine serum (FBS.  Human umbilical cord blood (hUCB has been reported to have low immunogenic property and potential in wound healing, so therefore hUCB serum (hUCBS could be potential and were investigated in current study. Materials and Methods: Five hUCBs were collected from healthy volunteers with normal delivering procedure. hUCB was ex utero immediately collected from umbilical vein in vacutainers and processed. NIH3T3 cells were cultured in DMEM with 10% FBS or 5-20% hUCBS for 48 hours. Cells were then quantified using MTT assay. Protein concentration of FBS and hUCBS were quantified using Bradford assay. Results: NIH3T3 cells density grown in DMEM with 10% FBS was the lowest. NIH3T3 cells densities were increased along with the increment of hUCBS concentrations. MTT results showed that average number of NIH3T3 cells grown in DMEM with 10% FBS was 6,185±1,243. Meanwhile average numbers of NIH3T3 cells grown in DMEM with 5%, 10% and 20% hUCBS were 8,126±628, 9,685±313 and 12,200±304, respectively. Average numbers of NIH3T3 cells grown in DMEM with 5% hUCBS were significantly higher than the ones with 10% FBS (p=0.000. Bradford results showed that concentration of hUCBS was significantly higher than the one of FBS (p=0.000. Conclusion: hUCBS could induce higher proliferation rate of NIH3T3 cells than FBS. Hence hUCBS could be suggested as an alternate of FBS in inducing fibroblast. Keywords: NIH3T3, fibroblast, UCB, serum, FBS, proliferation

    To determine effects of the biochemical and cytological properties of blood, serum, and ascites on survival of patients with malignant peritoneal effusion (MPeE), including malignant peritoneal mesothelioma (MPeM) and peritoneal carcinomatosis (PC), we conducted a retrospective study of patients with MPeE and healthy controls. Potential prognostic factors were identified as follows: age, sex, blood neutrophil-to-lymphocyte ratio (NLR), serum parameters, ascites parameters, serum-ascites albumin gradient, and the ascites-serum LDH ratio. Compared to those of the control group, serum albumin levels were significantly lower, and the NLR and serum LDH levels were significantly higher in the MPeE group. Overall survival (OS) was longer in patients with MPeM compared to that in patients with PC. Compared with patients in the MPeM, patients with PC had higher NLRs, ascites glucose levels, serum-ascites albumin gradients, and serum LDH levels. In contrast, their ascites albumin levels and ascites-serum LDH ratios were lower. Univariate analyses indicated that the NLR, serum LDH levels, ascites LDH levels, ascites coenocyte levels, and the ascites coenocyte-to-monocyte ratios affected the OS. Multivariate analyses identified only serum and ascites LDH levels as independent prognostic factors.

    High fat, low carbohydrate (HFLC) diets have become popular tools for weight management. We sought to determine the effects of a HFLC diet compared to a low fat high carbohydrate (LFHC) diet on the change in weight loss, cardiovascular risk factors and inflammation in subjects with obesity. Obese subjects (29.0-44.6 kg/m2) recruited from Boston Medical Center were randomized to a hypocaloric LFHC (n=26) or HFLC (n=29) diet for 12 weeks. The age range of subjects was 21-62 years. As a percentage of daily calories, the HFLC group consumed 33.5% protein, 56.0% fat and 9.6% carbohydrate and the LFHC group consumed 22.0% protein, 25.0% fat and 55.7% carbohydrate. The change in percent body weight, lean and fat mass, blood pressure, flow mediated dilation, hip:waist ratio, hemoglobin A1C, fasting insulin and glucose, and glucose and insulin response to a 2h oral glucose tolerance test did not differ (P>0.05) between diets after 12 weeks. The HFLC group had greater mean decreases in serum triglyceride (P=0.07), and hs-CRP (P=0.03), and greater mean increases in HDL cholesterol (P=0.004), and total adiponectin (P=0.045) relative to the LFHC. Secreted adipose tissue adiponectin or TNF-α did not differ after weight loss for either diet. Relative to the LFHC group, the HFLC group had greater improvements in blood lipids and systemic inflammation with similar changes in body weight and composition. This small-scale study suggests that HFLC diets may be more beneficial to cardiovascular health and inflammation in free-living obese adults compared to LFHC diets. © 2013.

    This study aims at investigating the effect of an experimental period of intake of whole grain foods rich in lignans as part of an habitual diet on the plasma and urinary excretion of enterolignans, the biomarkers of lipid metabolism and the immunological and antioxidant status in a group of postmenopausal women with moderate serum cholesterol. A randomized double-blind crossover study was completed on 13 subjects in 12-weeks after protocol approval of an ethical committee. The subjects consumed whole grain foods high in lignans (30 g/d of breakfast cereals or biscuits, etc., 80 g/d of whole grain pasta) or refined grain foods for 4 weeks, separated by a 2-weeks wash-out period. A modest hypocholesterolemic effect (p < 0.05) of the whole grain diet was observed and the intake of whole grain products rich in lignans was also associated with an increase in urinary enterodiol excretion (p < 0.05).

    Full Text Available This experiment was conducted to investigate the effects of different levels of L-carnitine on productive performance, egg quality and blood parameters in laying hens. Forty-eight Hy-Line W-36 egg Layers were weighed at 90 weeks of age and randomly allocated into 16 cages (three hens per cage. Four dietary treatments were prepared by supplementing L-carnitine (0, 50, 100 and 150 mg/kg of diet to corn-soybean meal diet and offered ad libitum to hens. After two weeks of acclimatization, the eggs were weighed daily and feed intake as well as egg quality traits were measured biweekly. At the end of the experiment, two hens from each cage were selected to determine blood parameters and two eggs from each replicate were collected for cholesterol analysis. Results showed that L-carnitine supplementation at 100 and 150 mg/kg significantly increased egg production and egg mass, but decreased yolk cholesterol content. Laying hens receiving diet containing 50 mg/kg L-carnitine had significantly higher Hough unit, but lower progesterone than the hens fed control diet (P < 0.05. The results of this study showed that supplementing hens' diet with L-carnitine had beneficial effects on productive performance and decreased yolk cholesterol concentration; so it can be used as an effective supplement in the diet of laying hens.

    The aim of the study was to evaluate the potential effect of different levels of sumac (Rhus coriaria L.) seed powder and ginger (Zingiber officinale) root powder on egg yolk fatty acid composition, blood/yolk cholesterol in laying hen. A total of 63 (ATAK-S: Domestic Turkish Laying Hens) laying hens (average weight: 1470 g each hen, 25-weeks of age) were assigned to seven treatment diets including sumac seed (S) and ginger root powder (G) at 0 g/kg (control), 10 g/kg (S1), 20 g/kg (S2), and 30 g/kg (S3); 10 g/kg (G1), 20 g/kg (G2), or 30 g/kg in rations respectively, for 8 weeks. After a two-week adaptation period to cages, the hens were allocated to 7 groups with 9 replicates of 1 hen in per cage each. The replications were allotted equally into the upper and lower cages to minimize the effects of cage level. In this study, egg yolk cholesterol had a decrease (p <0.05) in supplemented diet( sumac seed and ginger root powder). Fatty acid content in yolk; saturated fatty acid, monounsaturated fatty acids, polyunsaturated fatty acids and rate of n6/n3 were not significant (p <0.05). However, dietary supplementation with sumac and ginger powder reduced and yolk/blood cholesterol concentrations in laying hens. Supplementation of sumac and ginger affected on HDL, there was found a significant effect (p < 0.05) in treatment groups. Moreover, LDL positively decreased in all treatment groups compared with the control group. The findings of this study suggested that feeding sumac and ginger tend to be decreasing cholesterol levels in both yolk and blood on laying hens. It can be concluded that ginger root and sumac seed powder can be used as an effective feed additive to improve fatty acid composition and yolk and blood cholesterol in ATAK-S laying hens.

    Dobiasova, M.; Schuetzova, M.

    1986-01-01

    A new method is described of cold labelling of blood serum, plasma and body fluids containing lecithin cholesterol acyltransferase (LCAT) and/or lipoproteins for radioassay to assess the cholesterol esterification rate. The method uses the principle of transfer, in refrigeration conditions, of 14 C-cholesterol from filter paper discs to the fluids. The preparation of the disc guarantees homogeneous labelling and high stability. The use of the labelling disc was shown to be reliable, easy and fast and suitable for accurate assessment of LCAT reaction, applicable in the widest possible enzyme concentration range. It was also, found suited for the measurement of the esterification rate of rabbit intraocular fluid which is a medium with the lowest contents of the substrate and LCAT. (L.O.)

    Metabolic syndrome (MetS) as defined by the Adult Treatment Panel (ATP) III criteria includes 3 metabolic parameters: serum glucose, triglycerides, and high-density lipoprotein cholesterol (HDL-C) measurements. However, the impact of each of the 3 metabolic parameters on cardiovascular disease (CVD) risk in African American women (AAW) is unknown. Therefore, we investigated CVD risk clusters associated with each of the 3 metabolic components of MetS in adult nondiabetic, overweight/obese AAW. We studied the clinical and metabolic CVD risk factors of 258 AAW (mean age, 42.4 +/- 8.4 years; mean body mass index, 33.4 +/- 8.0 (kg/m(2)). Fasting serum insulin, glucose, and C-peptide levels were obtained in each subject. Waist circumference and systolic and diastolic blood pressure were measured. Insulin sensitivity (Bergman minimal model method) and insulin resistance (homeostasis model assessment) were calculated. We examined the prevalence of MetS and its components associated with each of the 3 metabolic components (ie, serum glucose, HDL-C, and triglycerides) of the MetS as defined by ATP III. Worsening of any of the 3 metabolic parameters was associated with increasing waist circumference but not with age and body mass index nor with insulin, C-peptide, homeostasis model assessment of insulin resistance, and insulin sensitivity. As a group, the prevalence of MetS was 35.5% in our AAW. The prevalence of MetS increased 3-fold from first to third tertiles of serum glucose (14.1% and 42.3%, respectively). Worsening of serum HDL-C from tertiles 3 to 1 was associated with significant increases in the prevalence of MetS (1.2% vs 42.3%, respectively). Comparing first with third tertile of triglycerides, there was no significant increase in MetS in our AAW (7% vs 17%). Contrasting the 3 metabolic components, the prevalence of MetS was higher in the third tertile of glucose (43.2%) and first tertile of HDL-C (42.3%) and least with the third tertile of triglycerides (17%).

    High serum uric acid (sUA) has been reported to be a risk factor for hypertension however, whether this is the case for all age groups is not clear. We examined the association between sUA concentrations and systolic and diastolic blood pressure (SBP and DBP) in different age groups in a cohort of healthy Chinese participants.A total of 1082 healthy participants aged from 41 to 70 years were included. sUA concentration was measured by the uricase-peroxidase method. SBP and DBP were assessed using mercury sphygmomanometry. Hypertension was defined as SBP ≥140 mm Hg or DBP ≥90 mm Hg. Hyperuricemia (HUA) was defined as sUA concentration of >7 mg/dL in men and >6 mg/dL in women. The association between sUA concentration and SBP and DBP was examined using Pearson's correlation test, multivariate linear regression, and logistic regression analysis.The prevalence of hypertension and HUA increased with age (P age, sex, total cholesterol, estimated glomerular filtration rate, and fasting plasma glucose). HUA was also a risk factor for hypertension in this age group (odds ratio 1.425, 95% confidence interval, 1.217-1.668, P age groups.In this population of healthy Chinese participants, sUA concentration was positively associated with hypertension only in the 41- to 50-year-old group. Lowering uric acid in this age group may help to reduce the incidence of hypertension. Copyright © 2017 The Authors. Published by Wolters Kluwer Health, Inc. All rights reserved.

    The mass-spectra of proteome of blood serum from healthy children and children with gastroesophageal reflux disease were received. The technology platform including direct proteome mass-spectrometer profiling after pre-fractional rectification using magnetic particles MB WCX was applied. The significant differences in mass-spectra were established manifesting in detection of more mass-spectrometer peaks and higher indicators of their intensity and area in group of healthy children. The study detected 39 particular peptides and low-molecular proteins predominantly intrinsic to healthy or ill children. It was established that two peptides with molecular mass 925 and 909 Da. are registered only in healthy patients and have no traces in group ofpatients with gastroesophageal reflux disease. The peptide 1564 Da is detected only in blood of children with gastroesophageal reflux disease and totally is absent in healthy children. The research data permitted to reveal specific patterns (signatures) of low-molecular proteins and peptides specific for blood serum of healthy children and patients with gastroesophageal reflux disease. The results testify the availability of singularities in metabolism of low-molecular proteins and can be used as a basis for development of minimally invasive mass-spectrometer system for its diagnostic.

    Determining blood group antigens by serological methods may be unreliable in certain situations, such as in patients after chronic or massive transfusion. Red cell genotyping offers a complementary approach, but current methods may take much longer than conventional serological typing, limiting their utility in urgent situations. To narrow this gap, we devised a rapid method using direct polymerase chain reaction (PCR) amplification while avoiding the DNA extraction step. DNA was amplified by PCR directly from plasma or serum of blood donors followed by a melting curve analysis in a capillary rapid-cycle PCR assay. We evaluated the single nucleotide polymorphisms underlying the clinically relevant Fya, Fyb, Jka and Jkb antigens, with our analysis being completed within 40 min of receiving a plasma or serum sample. The positive predictive value was 100% and the negative predictive value at least 84%. Direct PCR with melting point analysis allowed faster red cell genotyping to predict blood group antigens than any previous molecular method. Our assay may be used as a screening tool with subsequent confirmatory testing, within the limitations of the false-negative rate. With fast turnaround times, the rapid-cycle PCR assay may eventually be developed and applied to red cell genotyping in the hospital setting. PMID:27991657

This meta-analysis was performed to evaluate the effects of extracted soy isoflavones alone (not ingested concurrently with soy protein on total and low density lipoprotein (LDL cholesterol. MEDLINE (1966–2007, EMBASE (1966–2007, CENTRAL (1966–2007, ICHUSHI (1983–2008, and CNKI (1979–2007 were searched for randomized placebo-controlled trials published in English, Japanese, and Chinese, describing the changes in lipid profiles in adult humans resulting from ingestion of extracted soy isoflavones for 1–3 months. Reference lists of relevant systematic reviews and meta-analyses were hand-searched. Meta-analysis of 10 and 9 trials with usable information using REVMAN found that an average of 70 mg soy isoflavones/day (27–132 mg, as the aglycone form alone had a nonsignificant effect on total (0.01 mmol/L [95% CI: –0.12, 0.14]; P = 0.86 and LDL (0.03 mmol/L [95% CI: –0.11, 0.16]; P = 0.71 cholesterol in menopausal women, respectively. It is concluded that ingestion of about 70 mg extracted soy isoflavones/day alone for 1–3 months does not improve total and LDL cholesterol levels in normocholesterolemic menopausal women; further studies are needed to verify the effects of extracted soy isoflavones.Keywords: extracted soy isoflavones, lipid, total cholesterol, LDL cholesterol

    Full Text Available The significance of maternal cholesterol transporting to the fetus under normal as well as pathological circumstances is less understood. The objective of this study was to observe the effects of maternal hypercholesterolemia on placental cholesterol transportation. Human full-time placenta, maternal and venous cord blood were sampled at delivery from the pregnant women with serum total cholesterol (TC concentrations at third trimester higher than 7.25 mM (n = 19 and the pregnant women with normal TC concentrations (n = 19. Serum lipids and expression of genes related to cholesterol transportation were measured by western blot or real-time PCR. The results indicated that serum TC, high density lipoprotein cholesterol (HDL-C, and low density lipoprotein cholesterol (LDL-C levels were significantly increased, in pregnancies, but decreased in cord blood in hypercholesterolemic group compared to the matched control group. All the subjects were no-drinking, non-smoker, and gestational disease free. The mRNA expression of lipoprotein receptors, including LDLR and VLDLR were significantly increased, while the protein expression of PCSK9 was significantly increased in hypercholesterolemic placenta. In conclusion, maternal hypercholesterolemia might decrease the transportation of cholesterol from mother to fetus because of the high levels of PCSK9 protein expression.

    This paper proposes a novel method for measuring blood plasma and serum viscosity with a microcantilever-based MEMS sensor. MEMS cantilevers are made of electroplated nickel and actuated remotely with magnetic field using an electro-coil. Real-time monitoring of cantilever resonant frequency is performed remotely using diffraction gratings fabricated at the tip of the dynamic cantilevers. Only few nanometer cantilever deflection is sufficient due to interferometric sensitivity of the readout. The resonant frequency of the cantilever is tracked with a phase lock loop (PLL) control circuit. The viscosities of liquid samples are obtained through the measurement of the cantilever's frequency change with respect to a reference measurement taken within a liquid of known viscosity. We performed measurements with glycerol solutions at different temperatures and validated the repeatability of the system by comparing with a reference commercial viscometer. Experimental results are compared with the theoretical predictions based on Sader's theory and agreed reasonably well. Afterwards viscosities of different Fetal Bovine Serum and Bovine Serum Albumin mixtures are measured both at 23°C and 37°C, body temperature. Finally the viscosities of human blood plasma samples taken from healthy donors are measured. The proposed method is capable of measuring viscosities from 0.86 cP to 3.02 cP, which covers human blood plasma viscosity range, with a resolution better than 0.04 cP. The sample volume requirement is less than 150 μl and can be reduced significantly with optimized cartridge design. Both the actuation and sensing are carried out remotely, which allows for disposable sensor cartridges. Copyright © 2013. Published by Elsevier Inc.

    Serum lipid profile has now become almost a routine test. It is usually done in fasting state due to certain limitations in non-fasting serum sample. In the recent past efforts have been made to simplify blood sampling by replacing fasting lipid profile with non-fasting lipid profile. However, fasting specimen is preferred if cardiovascular risk assessment is based on total cholesterol, LDL cholesterol or non-HDL cholesterol. A lot has yet to be done in this area.

    Eighty-two samples of serum and red blood cells from 32 normal subjects and 50 patients with hypertension, old myocardial infarct and diabetes mellitus were analyzed by neutron activation analysis for copper, zinc and molybdenum. The mean value of copper in the normal serum (0.56 μg/g) was found to be lower than the reported mean values of 1.13 μg/g and 1.15 μg/g for foreign subjects. The mean value of copper in the normal red blood cells (0.55 μg/g) was also found to be lower than the reported values of 0.92 μg/g and 0.95 μg/g among foreigners. The mean concentration of copper in the serum of patients with hypertension and old myocardial infarct (1.02+-0.25 μg/g) and diabetes mellitus (1.06+-0.02 μg/g) were higher than the normal value of 0.56+-0.15 μg/g. The mean concentration of zinc in the serum of patients with hypertension and old myocardial infarct (0.74+-0.38 μg/g) and in diabetes mellitus (0.61+-0.33 μg/g) were lower than the normal value of 1.25+-0.58 μg/g. The level of copper in the red blood cells of patients with hypertension and old myocardial infarct (0.99+-0.62 μg/g) and diabetes mellitus (0.75+-0.39 μg/g) were found to be higher than the normal value of (0.55+-0.41) μg/g). The mean concentration of molybdenum in the red blood cells of patients with hypertension and old myocardial infarct (1.16+-0.73 μg/g) and diabetes mellitus (1.55+-0.91 μg/g) were higher than the normal level of 0.73+-0.43 μg/g.

    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.

    Full Text Available Aim: Due to the potential toxicity of high concentrations of bilirubin, newborns are monitored in terms of the potential emergence of a group at risk of the development of severe hyperbilirubinaemia and, rarely, encephalopathy and kernicterus. The transcutaneous measurement of bilirubin, as a non-invasive method, is applied in neonatal centres. The paper presents an evaluation of the correlation between the transcutaneous measurement and the concentration of bilirubin in the blood serum of a newborn, taking into consideration the reduction of the necessity to carry out blood tests related to the transcutaneous measurement. Material and method: The analysis comprised 1,076 medical histories of newborns hospitalised at the Department of Neonatology of the Municipal Hospital in Zabrze in the period from 1 January to 31 December 2013 (a primary referral centre. The inclusion criteria for the study were: performing a simultaneous transcutaneous measurement and a blood serum concentration measurement of bilirubin, gestational age ≥35 Hbd and birth weight >2,500 g. 272 children were qualified for the study. Results: Boys constituted 51.7%, and girls 48.3% of the research group. The mean gestational age was 38.7 Hbd and the mean birth weight was 3,323.4 g; 67.8% of the children were born by natural labour and 32.2% – by caesarean section. The mean Apgar score in the 5th minute was 9.8 points. The measurement of the concentration of bilirubin was performed on average on the 3.9 day of life. The mean transcutaneous measurement was 9.67 mg% (2.7–17.2 mg% and the mean concentration of bilirubin in the blood serum was 13.18 mg% (7.0–19.8 mg%; the difference was 3.5 mg% (p < 0.0001. A statistically significant positive correlation was found between the concentrations of bilirubin obtained in the transcutaneous measurement and the concentrations in the blood serum (according to Spearman, r

    Interest in human exposure to perfluorinated acids, including perfluorobutanesulfonate (PFBS), perfluorohexanesulfonate (PFHS), perfluorooctanesulfonate (PFOS), and perfluorooctanoate (PFOA) has led to their measurement in whole blood, plasma and serum. Comparison of measurements in these different blood-based matrices, however, has not been rigorously investigated to allow for across-matrix comparisons. This research evaluated concentrations of PFBS, PFHS, PFOS, and PFOA in whole blood collected in heparin (lithium) and ethylenediamine tetraacetic acid (EDTA), plasma samples collected in heparin and EDTA, and serum (from whole blood allowed to clot). Blood samples were collected from 18 voluntary participants employed at 3M Company. Solid phase extraction methods were used for all analytical sample preparations, and analyses were completed using high-pressure liquid chromatography/tandem mass spectrometry methods. Serum concentrations ranged from: limit of quantitation (LOQ, 5 ng/mL) to 25 ng/mL for PFBS; LOQ (5 ng/mL) to 75 ng/mL for PFHS; LOQ (5 ng/mL) to 880 ng/mL for PFOS; and LOQ (5 or 10 ng/mL) to 7320 ng/mL for PFOA. Values less than the LOQ were not included in the statistical analyses of the mean of the ratios of individual values for the matrices. PFBS was not quantifiable in most samples. Serum to plasma ratios for PFHS, PFOS, and PFOA were 1:1 and this ratio was independent of the level of concentrations measured. Serum or plasma to whole blood ratios, regardless of the anticoagulant used, approximated 2:1. The difference between plasma and serum and whole blood corresponded to volume displacement by red blood cells, suggesting that the fluorochemicals are not found intracellularly or attached to the red blood cells

A total of 120 Hy-Line Brown laying hens (75 weeks old) were randomly allotted to 1 of 3 dietary treatments with 4 replicates per treatment. A commercial-type basal diet was prepared, and 2 additional diets were prepared by supplementing 5.0 or 10.0 g/kg of RGB to the basal diet at the expense of corn. The diets were fed to hens on an ad libitum basis for 4 weeks. There were no differences in feed intake, egg weight, and feed conversion ratio during 4 weeks of the feeding trial. However, hen-day egg production was significantly greater (p<0.05) for the RGB treatment groups than that for the basal treatment group. There were no differences in triglyceride, aspartate aminotransferase, and alanine aminotransferase during the 4-week feeding trial. However, RGB supplementation increased (p<0.05) the serum immunoglobulin G (IgG) and IgM content compared with basal treatment group. The total cholesterol was lower (p<0.05) in the RGB treatments groups than that in the basal treatment group. The intestinal Lactobacillus population was greater (p<0.05) for the RGB treatments groups than that for the basal treatment group. However, the numbers of Salmonella and Escherichia coli were not different among dietary treatments. During the entire experiment, there was no significant difference in egg quality among all the treatments. In conclusion, in addition to improving hen-day production, there were positive effects of dietary RGB supplementation on serum immunoglobulin and cholesterol levels in laying hens.

    Full Text Available The aim of the study was to determine the serum level of homocysteine in children with neuroinfections.Mаterials and methods: A blood serum assay of 60 children with viral and bacterial neuroinfections was performed using the enzyme immunoassay to evaluate homocysteinemia as a marker of endothelial dysfunction.Results: In interpreting the results, the average level of hyperhomocysteinemia in patients with bacterial and viral neuroinfections was established. The highest homocysteine levels in serum were observed in bacterial neuroinfections, especially in the presence of signs of meningoencephalitis and pneumococcal etiology of the disease. Dependence of changes in the level of homocysteinemia from the sex of sick children was not revealed.Conclusion: Neuroinfections in children, regardless of the cause, are accompanied by hyperhomocysteinemia, indicating the presence of endothelial activation in this pathology, more pronounced in the case of a bacterial etiology of the infectious process and the combined lesion of the soft dura mater and the brain substance.

    Pemphigus vulgaris is a chronic, autoimmune, blistering disease of the skin and mucous membranes with a potentially fatal outcome. In this case micro-Raman spectroscopy (μ-RS) can provide a powerful tool for a not invasive analysis of biological tissue for biopsy and in vivo investigation. Based on the evaluation of molecular vibration frequencies, the μ-RS is able to detect the main molecular bonds of protein constituents, as the C-H and C-C ones. Changes in frequency or in the relative intensity of the vibration modes revealed by μ-RS can be related to changes of chemical bond and of protein structure induced by pathology. Quantitative information on the intensity variation of specific Raman lines can be extracted by Partial Least Square (PLS) analysis. μ-RS was performed on some samples of oral tissue and blood serum from informed patients affected by pemphigus vulgaris (an oral pathology) at different pathology stages. The spectra were measured by means of a Raman confocal microspectrometer apparatus using the 633 nm line of a He- Ne laser source. The main protein bonds are clearly detectable in the considered samples giving important information on the integrity and on the state of tissue and blood serum components (lipids and proteins), and consequently on the occurrence of pathology.

    The objective of the present study was to monitor the levels of organochlorine pesticides HCB; α-, β-, γ-HCH; pp'DDE; op'DDT; and pp'DDT in blood serum of Veracruz, Mexico inhabitants. Organochlorine pesticides were analyzed in 150 blood serum samples that constituted that which remained after clinical analyses, using gas chromatography-electron-capture detection (GC-ECD). The results were expressed as milligrams per kilogram on fat basis and micrograms per liter on wet weight. Only the following pesticides were detected: p,p'-DDE was the major organochlorine component, detected in 100% of samples at mean 15.8 mg/kg and 8.4 μg/L; p,p'-DDT was presented in 41.3.% of monitored samples at mean 3.1 mg/kg and 1.4 μg/L; β-HCH was found in 48.6% of the samples at mean 4.9 mg/kg and 2.7 μg/L; op'DDT was determined to be in only 3.3% of monitored samples at mean 2.7 mg/kg and 1.4 μg/L. The pooled samples divided according to sex showed significant differences of β-HCH and pp'DDE concentrations in females. The samples grouped according to age presented the third tertile as more contaminated in both sexes, indicating age as a positively associated factor with serum organochlorine pesticide levels in Veracruz inhabitants.

    Full Text Available Cardiovascular diseases are one of the major causes of deaths in adults in the western world. Elevated levels of certain blood lipids have been reported to be the principal cause of cardiovascular disease and other disabilities in developed countries. Several animal and clinical trials have shown a positive association between cholesterol levels and the risks of coronary heart disease. Current dietary strategies for the prevention of cardiovascular disease advocate adherence to low-fat/low-saturated-fat diets. Although there is no doubt that, in experimental conditions, low-fat diets offer an effective means of reducing blood cholesterol concentrations on a population basis, these appear to be less effective, largely due to poor compliance, attributed to low palatability and acceptability of these diets to the consumers. Due to the low consumer compliance, attempts have been made to identify other dietary components that can reduce blood cholesterol levels. Supplementation of diet with fermented dairy products or lactic acid bacteria containing dairy products has shown the potential to reduce serum cholesterol levels. Various approaches have been used to alleviate this issue, including the use of probiotics, especially Bifidobacterium spp. and Lactobacillus spp.. Probiotics, the living microorganisms that confer health benefits on the host when administered in adequate amounts, have received much attention on their proclaimed health benefits which include improvement in lactose intolerance, increase in natural resistance to infectious disease in gastrointestinal tract, suppression of cancer, antidiabetic, reduction in serum cholesterol level, and improved digestion. In addition, there are numerous reports on cholesterol removal ability of probiotics and their hypocholesterolemic effects. Several possible mechanisms for cholesterol removal by probiotics are assimilation of cholesterol by growing cells, binding of cholesterol to cellular surface

    Full Text Available INTRODUCTION: Erythrocytes carry apolipoprotein B on their membrane, but the determining factors of erythrocyte-bound apolipoprotein B (ery-apoB are unknown. We aimed to explore the determinants of ery-apoB to gain more insight into potential mechanisms. METHODS: Subjects with and without CVD were included (N = 398. Ery-apoB was measured on fresh whole blood samples using flow cytometry. Subjects with ery-apoB levels ≤ 0.20 a.u. were considered deficient. Carotid intima media thickness (CIMT was determined as a measure of (subclinical atherosclerosis. RESULTS: Mean ery-apoB value was 23.2% lower in subjects with increased CIMT (0.80 ± 0.09 mm, N = 140 compared to subjects with a normal CIMT (0.57 ± 0.08 mm, N = 258 (P = 0.007, adjusted P<0.001. CIMT and ery-apoB were inversely correlated (Spearman's r: -0.116, P = 0.021. A total of 55 subjects (13.6% were considered ery-apoB deficient, which was associated with a medical history of CVD (OR: 1.86, 95% CI 1.04-3.33; adjusted OR: 1.55; 95% CI 0.85-2.82. Discontinuation of statins in 54 subjects did not influence ery-apoB values despite a 58.4% increase in serum apolipoprotein B. Subjects with blood group O had significantly higher ery-apoB values (1.56 ± 0.94 a.u. when compared to subjects with blood group A (0.89 ± 1.15 a.u, blood group B (0.73 ± 0.1.12 a.u. or blood group AB (0.69 ± 0.69 a.u. (P-ANOVA = 0.002. CONCLUSION: Absence or very low values of ery-apoB are associated with clinical and subclinical atherosclerosis. While serum apolipoprotein B is not associated with ery-apoB, the ABO blood group seems to be a significant determinant.

    In this study, serum zinc and lipoprotein concentrations were determined in order to assess the health status of an elderly population residing in Sao Paulo city, SP, Brazil. This population consisted of elderly considered healthy and participating of a 'Successful Ageing' program of the Sao Paulo University Medical School. Fasting blood samples were collected from 87 elderly individuals (63 females and 24 males) aged 60-91 and mean age of 72 +- 7 years. Zn concentrations were determined by neutron activation analysis at the IPEN/CNEN/ SP and, the lipoprotein (HDL, LDL and total cholesterol) concentrations were determined using routine analysis methods of the Central Laboratory Division, Hospital das Clinicas, FMUSP. Results obtained for Zn indicated that all the individuals presented this element within the recommended value. For total cholesterol and HDL-cholesterol concentrations, 96 % of elderly presented levels within the desired range but for LDL cholesterol concentrations only about 70.0 % of individuals were in the desired range. Serum concentration of Zn were positively correlated to LDL-cholesterol levels (correlation coefficient r = 0.21, p < 0.06). Furthermore, the ratios of [HDL-cholesterol] / [LDL-cholesterol] were negatively correlated with Zn concentrations (r = - 0.234, p < 0.04). The positive correlation found between the serum concentrations of Zn and LDL-cholesterol indicates the possible effect of this element in serum lipoprotein profiles. Thus ,these findings suggest that more investigations should be conducted on Zn supplementation in elderly subjects with cardiovascular diseases. (author)

    Full Text Available BackgroundMetabolic dysfunctions characteristic of overt hypothyroidism (OH start at the early stage of subclinical hypothyroidism (SCH. Na+/K+-ATPase (the sodium pump is a transmembrane enzyme that plays a vital role in cellular activities in combination with membrane lipids. We evaluated the effects of early changes in thyroid hormone and membrane cholesterol on sodium pump activity in SCH and OH patients.MethodsIn 32 SCH patients, 35 OH patients, and 34 euthyroid patients, sodium pump activity and cholesterol levels in red blood cell membranes were measured. Serum thyroxine (T4 and thyroid stimulating hormone (TSH levels were measured using enzyme-linked immunosorbent assays. Differences in their mean values were analysed using post hoc analysis of variance. We assessed the dependence of the sodium pump on other metabolites by multiple regression analysis.ResultsSodium pump activity and membrane cholesterol were lower in both hypothyroid groups than in control group, OH group exhibiting lower values than SCH group. In SCH group, sodium pump activity showed a significant direct dependence on membrane cholesterol with an inverse relationship with serum TSH levels. In OH group, sodium pump activity depended directly on membrane cholesterol and serum T4 levels. No dependence on serum cholesterol was observed in either case.ConclusionDespite the presence of elevated serum cholesterol in hypothyroidism, membrane cholesterol contributed significantly to maintain sodium pump activity in the cells. A critical reduction in membrane cholesterol levels heralds compromised enzyme activity, even in the early stage of hypothyroidism, and this can be predicted by elevated TSH levels alone, without any evident clinical manifestations.

    Full Text Available Allicin was discussed as an active compound with regard to the beneficial effects of garlic in atherosclerosis. The aim of this study was to investigate the cholesterol-lowering properties of allicin. In order to examine its effects on hypercholesterolemia in male ICR mice, this compound with doses of 5, 10, or 20 mg/kg body weight was given orally daily for 12 weeks. Changes in body weight and daily food intake were measured regularly during the experimental period. Final contents of serum cholesterol, triglyceride, glucose, and hepatic cholesterol storage were determined. Following a 12-week experimental period, the body weights of allicin-fed mice were less than those of control mice on a high-cholesterol diet by 38.24±7.94% (P<0.0001 with 5 mg/kg allicin, 39.28±5.03% (P<0.0001 with 10 mg/kg allicin, and 41.18±5.00% (P<0.0001 with 20 mg/kg allicin, respectively. A decrease in daily food consumption was also noted in most of the treated animals. Meanwhile, allicin showed a favorable effect in reducing blood cholesterol, triglycerides, and glucose levels and caused a significant decrease in lowering the hepatic cholesterol storage. Accordingly, both in vivo and in vitro results demonstrated a potential value of allicin as a pronounced cholesterol-lowering candidate, providing protection against the onset of atherosclerosis.

    In this study, we aimed at comparing the effects of standard once daily 20 mg atorvastatin treatment with that of atorvastatin 20 mg administered every other day on serum lipids and high sensitive C-reactive protein (hs-CRP) levels. Sixty-one patients with serum total cholesterol levels of above 200 mg/dl and low density lipoprotein (LDL)--cholesterol levels of above 130 mg/dl were included in this prospective, randomized study. The patients were randomized into daily treatment of 20 mg atorvastatin (standard treatment) and 20 mg atorvastatin every other day (every other day treatment) groups. Before the treatment and at each visit, serum lipids and hs-CRP levels of all the patients were measured. Statistical analyses were performed Chi-square, unpaired t and two-way repeated measurements ANOVA tests. In the every other day treatment group, there was a 36.1% reduction in LDL-cholesterol levels by the end of first month (p0.05). The LDL cholesterol levels of the group receiving 20 mg atorvastatin every day was reduced by %41 by the end of 1 month (pevery other day, there was a 21% decrease in hs-CRP levels compared to the basal measurements at the end of first month (pevery day the decrease in hs-CRP levels at the end of one month was more striking (37%, p0.05). Alternate-day dosing of atorvastatin causes a significant lipid-lowering and antiinflammatory effects similar to that of daily administration and yet may provide some cost savings.

    A study was conducted to evaluate the effect of adding inulin to diets containing 2 different types of fat as energy sources on performance, blood serum metabolites, liver lipids, and fatty acids of abdominal adipose tissue and breast and thigh meat. A total of 240 one-day-old female broiler chicks were randomly allocated into 1 of 6 treatments with 8 replicates per treatment and 5 chicks per pen. The experiment consisted of a 3 x 2 factorial arrangement of treatments including 3 concentrations of inulin (0, 5, and 10 g/kg of diet) and 2 types of fat [palm oil (PO) and sunflower oil (SO)] at an inclusion rate of 90 g/kg of diet. The experimental period lasted from 1 to 34 d. Dietary fat type did not affect BW gain but impaired feed conversion (P abdominal fat deposition and serum lipid and glucose concentrations. Triacylglycerol contents in liver were higher in the birds fed PO diets. Dietary fat type also modified fatty acids of abdominal and i.m. fat, resulting in a higher concentration of C16:0 and C18:1n-9 and a lower concentration of C18:2n-6 in the birds fed PO diets. The addition of inulin to diets modified (P = 0.017) BW gain quadratically without affecting feed conversion. Dietary inulin decreased the total lipid concentration in liver (P = 0.003) and that of triacylglycerols and very low density lipoprotein cholesterol (up to 31%) in blood serum compared with the control groups. The polyunsaturated fatty acid:saturated fatty acid ratio increased in abdominal and i.m. fat when inulin was included in the SO-containing diets. The results from the current study suggest that the addition of inulin to broiler diets has a beneficial effect on blood serum lipids by decreasing triacylglyceride concentrations The results also support the use of inulin to increase the capacity of SO for enhancing polyunsaturated fatty acid:saturated fatty acid ratio of i.m. fat in broilers.

    Purpose: To assess the level of fatigue during the course of adjuvant radiotherapy (RT) of breast cancer patients and its relation to anxiety, depression, serum cytokines, and blood count levels. Methods and Materials: Forty-one patients who received adjuvant RT after breast-conserving surgery were prospectively studied. All patients underwent RT without concomitant chemotherapy. Patients rated their fatigue with two standardized self-assessment instruments, the Fatigue Assessment Questionnaire and a visual analog scale on fatigue intensity, before RT, during weeks 1-5 of RT, and 2 months after RT completion. In addition, the anxiety and depression levels were assessed with the Hospital Anxiety and Depression Scale. A differential blood cell count and the serum levels of the cytokines interleukin (IL)-1β, IL-6, and tumor necrosis factor-α were determined in parallel to the fatigue assessments. Results: Fatigue intensity as assessed with the visual analog scale increased (p<0.001) until treatment week 4 and remained elevated until week 5. Two months after RT, the values had fallen to the pretreatment levels. Fatigue measured with the Fatigue Assessment Questionnaire did not increase significantly during treatment, but the subscores on physical (p=0.035) and cognitive (p=0.015) fatigue were elevated during treatment weeks 4 and 5. Affective fatigue did not change significantly. Anxiety, as rated with the Hospital Anxiety and Depression Scale, declined during RT (p=0.002), but the Hospital Anxiety and Depression Scale depression score did not change significantly. IL-1β, IL-6, and tumor necrosis factor-α levels did not change during therapy and did not correlate with fatigue. Peripheral blood cell levels declined significantly during therapy and were still low 2 months after treatment. Until treatment week 5, lymphocytes were reduced to almost 50% of their initial values. Hemoglobin levels did not correlate with fatigue. Conclusions: We observed an increase in

    To make the rapid separation of serum/blood cells possible in a whole bloodstream flow without centrifugation and Pasteur pipette suction, the first step is to use a microchannel to transport the whole bloodstream into a microdevice. Subsequently, the resulting serum/blood cell is separated from the whole bloodstream by applying other technologies. Creating the serum makes this subsequent separation possible. To perform the actual separation, a microchannel with multiple symmetric curvilinear microelectrodes has been designed on a glass substrate and fabricated with micro-electromechanical system technology. The blood cells can be observed clearly by black-field microscopy imaging. A local dielectrophoretic (DEP) force, obtained from nonuniform electric fields, was used for manipulating and separating the blood cells from a continuous whole bloodstream. The experimental studies show that the blood cells incur a local dielectrophoretic field when they are suspended in a continuous flow (v = 0.02-0.1 cm/s) and exposed to AC fields at a frequency of 200 kHz. Using this device, the symmetric curvilinear microelectrodes provide a local dielectrophoretic field that is sufficiently strong for separating nearby blood cells and purifying the serum in a continuous whole bloodstream flow.

    Several studies investigated the agreement between central laboratory biochemistry analyzers and blood gas analyzers for potassium measurements. However, data are scarce when the potassium level is moderate to severely high. We aimed to evaluate the agreement between central laboratory biochemistry analyzers and blood gas analyzer in terms of serum potassium level measurement because differences in potassium at this level translate into very different clinical actions. This was a retrospective medical record review study in which patients who presented to the emergency department and had serum potassium levels ≥6mmol/L were included. Patients who did not have simultaneous potassium measurement by blood gas analyzer were excluded. We included all patients meeting potassium criteria irrespective of their underlying disease or comorbidities. We evaluated agreement between the measurement methods with Pearson correlation, Bland-Altman plot, and Sign test. A total of 118 blood sample pairs were included. The mean serum potassium level measured by biochemistry analyzer was 6.78±0.79mmol/L, whereas it was 6.16±0.86mmol/L by blood gas analyzer (Pbiochemistry analyzer. The mean difference between the methods was 0.62±0.43mmol/L. In patients with moderate to severe hyperkalemia, blood gas analyzer and biochemistry analyzer gives significantly different serum potassium results which may be clinically important.

    Full Text Available Previously, we reported the effects of fescue toxicosis on developing Angus-cross steer growth, carcass, hepatic mRNA and protein expression profiles of selected serum proteins, and blood clinical and chemical profiles, after summer-long grazing (85 d of high (HE- vs low (LE-endophyte-infected fescue pastures. We now report the temporal development of acute, intermediate, and chronic responses of biochemical and clinical blood analytes determined at specified time intervals (period 1, d 0 to 36; period 2, d 37 to 58; and period 3, d 59 to 85. Throughout the trial, the alkaloid concentrations of the HE forage was consistently 19 to 25 times greater (P < 0.049 the concentration in the LE forage, and HE vs LE steers had continuously lower (P < 0.049 serum prolactin (85%, cholesterol (27%, and albumin (5%, but greater red blood cells (7%. The HE steers had decreased (P = 0.003 ADG only during period 1 (-0.05 vs 0.4 kg/d. For period 1, HE steers had reduced (P < 0.090 numbers of eosinophils (55% and lymphocytes (18%, serum triglyceride (27%, and an albumin/globulin ratio (9%, but an increased bilirubin concentration (20%. During period 2, serum LDH activities were 18% lower (P = 0.022 for HE vs LE steers. During period 3, serum levels of ALP (32%, ALT (16%, AST (15%, creatine kinase (35%, glucose (10%, and LDH (23% were lower (P < 0.040 for HE steers. Correlation analysis of serum prolactin and other blood analytes revealed that triglycerides (P = 0.042 and creatinine (P = 0.021 were moderately correlated (r < 0.433 with HE serum prolactin. In conclusion, three HE-induced blood analyte response patterns were identified: continually altered, initially altered and subsequently recovered, or altered only after long-term exposure. Blood analytes affected by length of grazing HE vs LE forages were either not, or poorly, correlated with serum prolactin. These data reveal important, temporal, data about how young cattle respond to the challenge of consuming

    Molecular methods have been developed for the detection and quantification of Trypanosoma cruzi DNA in blood samples from patients with Chagas disease. However, aspects of sample processing necessary for quantitative real-time PCR (qPCR), such as the addition of guanidine hydrochloride to whole blood samples, may limit timely access to molecular diagnosis. We analysed 169 samples from serum and guanidine-EDTA blood (GEB) obtained from patients in acute and chronic phases of Chagas disease. We applied qPCR targeted to the satellite DNA region. Finally, we compared the parasite loads and cycle of threshold values of the qPCR. The results confirmed the usefulness of serum samples for the detection and quantification of parasite DNA in patients with Chagas disease, especially in the acute phase. However, the parasite loads detected in serum samples from patients in the chronic phase were lower than those detected in GEB samples. The epidemiological implications of the findings are herein discussed.

    Emerging CVD risk factors (e.g. HDL function and central haemodynamics) may account for residual CVD risk experienced by individuals who meet LDL-cholesterol and blood pressure (BP) targets. Recent evidence suggests that these emerging risk factors can be modified by polyphenol-rich interventions such as soya, but additional research is needed. This study was designed to investigate the effects of an isoflavone-containing soya protein isolate (delivering 25 and 50 g/d soya protein) on HDL function (i.e. ex vivo cholesterol efflux), macrovascular function and blood markers of CVD risk. Middle-aged adults (n 20; mean age=51·6 (sem 6·6) years) with moderately elevated brachial BP (mean systolic BP=129 (sem 9) mmHg; mean diastolic BP=82·5 (sem 8·4) mmHg) consumed 0 (control), 25 and 50 g/d soya protein in a randomised cross-over design. Soya and control powders were consumed for 6 weeks each with a 2-week compliance break between treatment periods. Blood samples and vascular function measures were obtained at baseline and following each supplementation period. Supplementation with 50 g/d soya protein significantly reduced brachial diastolic BP (-2·3 mmHg) compared with 25 g/d soya protein (Tukey-adjusted P=0·03) but not the control. Soya supplementation did not improve ex vivo cholesterol efflux, macrovascular function or other blood markers of CVD risk compared with the carbohydrate-matched control. Additional research is needed to clarify whether effects on these CVD risk factors depend on the relative health of participants and/or equol producing capacity.

    The authors have reported AFP level in the blood serum of 2223 normal pregnant women in different semesters by RIA method. All the data were made by statistical analysis. The result shows that the AFP level is normal during the first 12 weeks of pregnancy. Then, it gradually increases from the 13th week and reaches its maximum (184.6 +- 74.6 μg/l) at 32nd week. Later on it tends to decrease slowly, but still remains over 100 μg/l in parturition period. Therefore, it is suggested that AFP in pregnant women has substantial difference and regularity between different semesters but without any significant correlation with their ages

    The heavy metal mercury (Hg) is a neurotoxin known to have a serious health impact even at relatively low concentrations. A slurry method was developed for the sensitive and precise determination of mercury in human serum blood samples by cold vapor generation coupled to atomic fluorescence spectrometry (CV-AFS). All variables related to the slurry formation were studied. The optimal hydrochloric concentration and tin(II) chloride concentration for CV generation were evaluated. Calibration within the range 0.1-10 μg L -1 Hg was performed with the standard addition method, and compared with an external calibration. Additionally, the reliability of the results obtained was evaluated by analyzing mercury in the same samples, but submitted to microwave-assisted digestion method. The limit of detection was calculated as 25 ng L -1 and the relative standard deviation was 3.9% at levels around of 0.4 μg L -1 Hg

    ABO blood typing in pre-transfusion testing is a major component of the high workload in blood banks that therefore requires automation. We often experienced discrepant results from an automated system, especially weak serum reactions. We evaluated the discrepant results by the reference manual method to confirm ABO blood typing. In total, 13,113 blood samples were tested with the AutoVue system; all samples were run in parallel with the reference manual method according to the laboratory protocol. The AutoVue system confirmed ABO blood typing of 12,816 samples (97.7%), and these results were concordant with those of the manual method. The remaining 297 samples (2.3%) showed discrepant results in the AutoVue system and were confirmed by the manual method. The discrepant results involved weak serum reactions (serum reactions, samples from patients who had received stem cell transplants, ABO subgroups, and specific system error messages. Among the 98 samples showing ≤1+ reaction grade in the AutoVue system, 70 samples (71.4%) showed a normal serum reaction (≥2+ reaction grade) with the manual method, and 28 samples (28.6%) showed weak serum reaction in both methods. ABO blood tying of 97.7% samples could be confirmed by the AutoVue system and a small proportion (2.3%) needed to be re-evaluated by the manual method. Samples with a 2+ reaction grade in serum typing do not need to be evaluated manually, while those with ≤1+ reaction grade do.

    End-stage liver disease (ESLD) is life-threatening and liver transplantation (LTx) is the definitive treatment with good outcomes. Given the essential role of hepatocytes in Cu homeostasis, the potential of the serum Cu isotopic composition for monitoring a patient’s condition post-LTx was evaluated. For this purpose, high-precision Cu isotopic analysis of blood serum of ESLD patients pre- and post-LTx was accomplished via multi-collector ICP-mass spectrometry (MC-ICP-MS). The Cu isotopic composition of the ESLD patients was fractionated in favour of the lighter isotope (by about -0.50‰). Post-LTx, a generalized normalization of the Cu isotopic composition was observed for the patients with normal liver function, while it remained light when this condition was not reached. A strong decrease in the δ65Cu value a longer term post-LTx seems to indicate the recurrence of liver failure or cancer. The observed trend in favour of the heavier Cu isotopic composition post-LTx seems to be related with the restored biosynthetic capacity of the liver, the restored hepatic metabolism and/or the restored biliary secretion pathways. Thus, Cu isotopic analysis could be a valuable tool for the follow-up of liver transplant patients and for establishing the potential recurrence of liver failure.

    Calcitonin and parathyroid hormone were determined using a radioimmunoassay in the blood serum of lung, breast and kidney cancer patients who had undergone combined treatment for major disease, healthy males, patients with spinal tuberculosis and patients with eosinophilic granuloma of the cranial bones. A significant rise of the calsitonin level and change in the ratio of calcitonin and the parathyroid hormone were established in the blood serum of patients with tumor metastases to the skeleton, spinal tuberculosis and eosiniphilic cranial granuloma. During cancer patients monitoring the determination of calcitonin is recommended as a screening test for sceletal metastases to select patients for γ-topographic investigation

    A new diagnostic approach based on Attenuated Total Reflectance-Fourier Transform Infrared (ATR-FTIR) spectrometry and classification algorithm has been introduced which provides a rapid, reliable, and easy way to perform blood test for the diagnosis of renal failure. Blood serum samples from 35 renal failure patients and 40 healthy persons were analyzed by ATR-FTIR spectrometry. The resulting data was processed by Quadratic Discriminant Analysis (QDA) and QDA combined with simple filtered method. Spectroscopic studies were performed in 900-2000 cm-1 spectral region with 3.85 cm-1 data space. Results showed 93.33% and 100% of accuracy for QDA and filter-QDA models, respectively. In the first step, 30 samples were applied to construct the model. In order to modify the capability of QDA in prediction of test samples, filter-based feature selection methods were applied. It was found that the filtered spectra coupled with QDA could correctly predict the test samples in most of the cases.

    Despite being ubiquitous in the fields of chemistry and biology, the ion-specific effects of electrolytes pose major challenges for researchers. A lack of understanding about ion-specific surface interactions has hampered the development and application of materials for (bio-)chemical sensor applications. Here, we show that scaling a silicon nanotransistor sensor down to 25 nm provides a unique opportunity to understand and exploit ion-specific surface interactions, yielding a surface that is highly sensitive to cations and inert to pH. The unprecedented sensitivity of these devices to Na+ and divalent ions can be attributed to an overscreening effect via molecular dynamics. The surface potential of multi-ion solutions is well described by the sum of the electrochemical potentials of each cation, enabling selective measurements of a target ion concentration without requiring a selective organic layer. We use these features to construct a blood serum ionogram for Na+, K+, Ca2+ and Mg2+, in an important step towards the development of a versatile, durable and mobile chemical or blood diagnostic tool.

    Full Text Available Abstract Background There are safety concerns regarding widespread consumption of phytosterol and phytostanol supplemented food products. The aim of this study was to determine, in the absence of excess dietary salt, the individual effects of excess accumulation of dietary phytosterols and phytostanols on blood pressure in Wistar Kyoto (WKY inbred rats that have a mutation in the Abcg5 gene and thus over absorb phytosterols and phytostanols. Methods Thirty 35-day old male WKY inbred rats (10/group were fed a control diet or a diet containing phytosterols or phytostanols (2.0 g/kg diet for 5 weeks. The sterol composition of the diets, plasma and tissues were analysed by gas chromatography. Blood pressure was measured by the tail cuff method. mRNA levels of several renal blood pressure regulatory genes were measured by real-time quantitative PCR. Results Compared to the control diet, the phytosterol diet resulted in 3- to 4-fold increases in the levels of phytosterols in plasma, red blood cells, liver, aorta and kidney of WKY inbred rats (P 9-fold the levels of phytostanols in plasma, red blood cells, liver, aorta and kidney of these rats (P P P P P angiotensinogen mRNA levels of these rats. Conclusion These data suggest that excessive accumulation of dietary phytosterols and phytostanols in plasma and tissues may contribute to the increased blood pressure in WKY inbred rats in the absence of excess dietary salt. Therefore, even though phytosterols and phytostanols lower cholesterol levels, prospective clinical studies testing the net beneficial effects of dietary phytosterols and phytostanols on cardiovascular events for subgroups of individuals that have an increased incorporation of these substances are needed.

    Intrauterine growth restriction (IUGR) is an important cause of perinatal morbidity and mortality and contributes substantially to medically indicated preterm birth; preventing fetal death. Molecular profiling of the mothers' peripheral blood was desired to monitor the health conditions of the fetuses. To develop such a minimally invasive assay, we applied a protein affinity fractionation method to peripheral blood serum samples from pregnant women belonging to either the IUGR or to the control group. Proof-of-principle was shown by relative quantitation analysis of mixtures of intact proteoforms using MALDI-ToF mass spectrometry. The two best differentiating proteins and proteoforms, respectively, were apolipoprotein C-II and apolipoprotein C-III 0 . Together with three robustly expressed protein proteoforms proapolipoprotein C-II, apolipoprotein C-III 1 , and apolipoprotein C-III 2 , which served as landmarks for relative quantitation analysis, they constituted the maternal IUGR proteome signature. Separation confidence of our IUGR proteoform signature reached a sensitivity of 0.73 and a specificity of 0.87 with an area under curve of 0.86 in receiver operator characteristics. Identification of IUGR newborns in the case room is required as children are severely diseased and need specialized care during infancy. Yet, at time of birth there is no readily applicable clinical test available. Hence, a molecular profiling assay is highly desired. It needs to be mentioned that current clinical definitions and recommendations for IUGR are unfortunately misleading and are not universally applicable. The most commonly adopted definition is an abdominal circumference (AC) or estimated fetal weight measurement protein composition (IUGR signature) which can be determined just ahead of delivery and at date of delivery, respectively using a minimal invasive blood sampling approach. With this manuscript we describe the use of a mass spectrometric profiling method of 30

    Measure of liver enzymes may help to increase safety of blood donation for both blood donor and recipient. Determination of liver enzymes may prepare valuable clinical information. To assess serum γ-Glutamyltransferase (GGT), Alanine Aminotransferase (ALT), and Aspartate Aminotransferase (AST) activities in healthy blood donors in different ethnic groups in Gorgan. This study was performed in 450 healthy male blood donors, in three ethnic groups (Fars, Sistanee and Turkman) who attended Gorgan blood transfusion center. Liver enzymes (GGT, ALT and AST) were determined. Serum AST and ALT in three ethnic groups were significant except for serum GGT levels. There was significant correlation between family histories of liver disease and systolic blood pressure and AST in Fars, and GGT in Sistanee ethnic groups. Several factors, such as age, family history of diabetes mellitus, family history of liver disease and smoking habit had no effect on some liver enzymes in different ethnic groups in this area. Variation of AST, ALT, and GGT enzyme activities in healthy subjects was associated with some subjects in our study groups. According to our study, it suggests that screening of AST and GGT enzymes in subjects with family history of liver disease is necessary in different ethnic groups.

    We developed a radioimmunoassay with a gamma-emitting radioligand to measure androstenedione in human serum and in dried blood-spot samples from newborns. Antisera were raised in rabbits against androstenedione linked to bovine serum albumin at positions 3, 6, or 11 on the steroid nucleus. Radioligands were prepared by linking ({sup 125}I)iodohistamine at positions 3, 6, or 11. Linkages were through either carboxymethyloxime or hemisuccinate bridges. All label and antibody combinations were examined, and the most sensitive and specific combination (antiserum raised against androstenedione-3-carboxymethyloxime-bovine serum albumin with an androstenedione-carboxymethyloxime-({sup 125}I)iodohistamine label) was selected for full evaluation. We report the performance of these selected reagents in an immunoassay for androstenedione in both serum and dried blood-spot samples from neonates. We measured concentrations of androstenedione in serum under normal and pathological conditions such as congenital adrenal hyperplasia and polycystic ovarian disease. Diurnal variation in normal men was observed. Androstenedione was measured in blood spots from neonates born at term or prematurely, with respiratory distress syndrome, or with congenital adrenal hyperplasia.

    This study aimed to evaluate the influence of exposure to aluminum, nickel, thallium and uranium on the metabolism of essential elements in humans, as well as the relationship between uranium, thallium, nickel, and aluminum and essential elements (Ca, Mg, Zn, Se, Mn, Co, Cr, and Mo) in the whole blood and blood serum of healthy men who were occupationally exposed. This study included 97 healthy men, 31-64 years age, including 70 workers in a thermo power plant and 27 control subjects. The results showed that chronic, moderate exposure of trace elements (Al, Ni, Tl, and U) lead to decreased serum chromium (SCr) and blood molybdenum levels (BMo), whereas by the results achieved in terms of correlations between non-essential and essential elements, non-essential elements such as uranium, thallium, nickel, and aluminum, despite their concentration within the reference values, are strongly competitive with essential elements in biochemical processes.

    Blood serum proteins are significant indicators of animal health. Nevertheless, several factors should be considered to appropriately interpret their concentrations in blood. Therefore, the objectives of this study were (1) to assess the effect of herd productivity, breed, age and stage of lactation on serum proteins and (2) to investigate association between serum proteins and somatic cell count (SCC) in dairy cattle. Milk and blood samples were collected from 1508 cows of six different breeds (Holstein Friesian, Brown Swiss, Jersey, Simmental, Rendena and Alpine Grey) that were housed in 41 multi-breed herds. Milk samples were analyzed for composition and SCC, while blood samples were analyzed for serum proteins (i.e. total protein, albumin, globulin and albumin-to-globulin ratio (A : G)). Herds were classified as low or high production, according to the cow's average daily milk energy yield adjusted for breed, days in milk (DIM) and parity. Data were analyzed using a linear mixed model that included the fixed effects of DIM, parity, SCS, breed, herd productivity and the random effect of the Herd-test date within productivity level. Cows in high producing herds (characterized also by greater use of concentrates in the diet) had greater serum albumin concentrations. Breed differences were reported for all traits, highlighting a possible genetic mechanism. The specialized breed Jersey and the two dual-purpose local breeds (Alpine Grey and Rendena) had the lowest globulin concentration and greatest A : G. Changes in serum proteins were observed through lactation. Total protein reached the highest concentration during the 4th month of lactation. Blood albumin increased with DIM following a quadratic pattern, while globulin decreased linearly. As a consequence, A : G increased linearly during lactation. Older cows had greater total protein and globulin concentrations, while albumin concentration seemed to be not particularly affected by age. A linear relationship

    Results with three commercial folate radioassay kits [Bio-Rad, New England Nuclear (NEN), and RIA Products] were compared with those by microbiological assay for more than 200 samples of human serum and whole blood. All but one kit (NEN) compared favorably with the microbiological assay for serum samples, although there were notable diagnostic discrepancies. Two kits (NEN and Bio-Rad) were tested on whole-blood samples; both yielded values significantly higher than those by microbiological assay. The frequency distributions of erythrocyte folate data differed strikingly between the two kits; the NEN method yielded a much narrower range of normal values than did either the Bio-Rad or the microbiological assay. Radioassay kits appear to be suitable diagnostic agents for serum folate, if the behavior of a particular kit is investigated thoroughly before its routine use. However, the diagnostic value of radioassays of erythrocyte folate needs to be validated

    Our investigations were concerned with dynamic changes in total lipids (CL), cholesterol (CHOL) and progesterone (P4) in blood serum of sheep in the period of oestrus synchronization treatment and during mating and gravidity. Our experiment was carried out using 10 animals housed under the conditions of productive rearing. Blood samples were taken from v. jugularis on day of swab application (day 0) and on days 3 and 7 of the action of Agelin vaginal swabs, on day of insemination, and on days 7, 14, 17 and in the 2nd, 3rd and 4th month of gravidity. Blood serum was used to determine total lipids and cholesterol by means of Bio-Lachema tests, and P4 concentrations employing RIA-test-Prog kits (URVJT, Kosice). A statistically significant decrease in concentrations of total lipids (Fig. 1, Tab. I) in sheep blood serum was recorded on day of insemination (P < 0.05) compared to day 0, with the value 1.59 +/- 0.31 g/l of serum, and in the 3rd month of gravidity (P < 0.01), at concentrations 1.36 +/- 0.38 g/l of serum. The determined decrease in their values in the mentioned period can be modulated by the mutually changing ratio of steroid hormones or by inhibition of synthesis of lipoproteins responsible for changes in total plasma lipids. Changes in cholesterol concentrations (Fig. 2, Tab. I) during the introduction of swabs were insignificant and ranged from 1.60 +/- 0.42 to 1.73 +/- 0.33 mmol/l of serum. An insignificant increase in cholesterol concentrations (P < 0.05), with its highest levels 1.98 +/- 0.43 mmol/l of serum, was recorded in the 3rd month of gravidity.(ABSTRACT TRUNCATED AT 250 WORDS)

    Technetium-99m red blood cells (Tc-RBC) labeled by an in vivo technique were compared with two preparations of Tc-99m human serum albumin (HSA) for cardiac blood-pool imaging. Relative distribution of the tracers was analyzed on end-diastolic frames of gated blood-pool studies and on whole-body (head to mid-thigh) anterior pinhole images. The Tc-RBC demonstrated greater relative percentage localization in the cardiac blood pool, higher target-to-background ratios in the left ventricle, and less liver concentration. For cardiac blood-pool imaging, Tc-RBC labeled by the in vivo approach appears to be superior to the two Tc-HSA preparations studied

    Posterior reversible encephalopathy syndrome (PRES) is a clinical-radiological entity affecting both adults and children characterized by neurotoxicity often in setting of hypertension coupled with distinct brain magnetic resonance imaging features. Decreased serum albumin level has been suggested to correlate with the presence of vasogenic brain edema in adult PRES. Serum albumin has thus been hypothesized to protect against neurotoxicity in PRES by reducing vasogenic brain edema through its role in maintaining plasma osmotic pressure and endothelial integrity. The purpose of our study was to investigate if such correlation between decreased serum albumin level and PRES-related vasogenic edema could be found in children. We conducted a retrospective study of 25 pediatric patients diagnosed with PRES. Underlying clinical conditions, presenting symptoms, blood pressures, and serum albumin levels at onset of symptoms were collected. Brain MR imaging studies were reviewed. We used a quantitative method to evaluate the degree of vasogenic edema by measuring apparent diffusion coefficient (ADC) values of the T2-FLAIR hyperintense brain lesions. No significant correlation was found between serum albumin level and degree of PRES-related vasogenic edema. A significant correlation was found between elevated blood pressure and degree of vasogenic edema in the temporal lobes (p = 0.02 and 0.04, respectively) but not in the other cerebral lobes or cerebellum. Our initial results suggest blood pressure, not serum albumin level, as a main biomarker for brain edema in children with PRES. Thus, our study does not suggest a protective role of serum albumin against PRES-related neurotoxicity in children. (orig.)

    Hepatitis is the second most common disease worldwide with half of the cases arising in the developing world. The mortality associated with hepatitis B and C can be reduced if the disease is detected at the early stages of development. The aim of this study was to investigate the potential of Raman spectroscopy as a diagnostic tool to detect biochemical changes accompanying hepatitis progression. Raman spectra were acquired from 20 individuals with six hepatitis B infected patients, six hepatitis C infected patients and eight healthy patients in order to gain an insight into the determination of biochemical changes for early diagnostic. The human blood serum was examined at a 532 nm excitation laser source. Raman characteristic peaks were observed in normal sera at 1006, 1157 and 1513 cm −1 , while in the case of hepatitis B and C these peaks were found to be blue shifted with decreased intensity. New Raman peaks appeared in HBV and HCV infected sera at 1194, 1302, 844, 905, 1065 and 1303 cm −1 respectively. A Mat lab subroutine and frequency domain filter program is developed and applied to signal processing of Raman scattering data. The algorithms have been successfully applied to remove the signal noise found in experimental scattering signals. The results show that Raman spectroscopy displays a high sensitivity to biochemical changes in blood sera during disease progression resulting in exceptional prediction accuracy when discriminating between normal and malignant. Raman spectroscopy shows enormous clinical potential as a rapid non-invasive diagnostic tool for hepatitis and other infectious diseases. (letter)

    The diverse clinical applications for human mesenchymal stem cells (hMSCs) in cellular therapy and regenerative medicine warrant increased focus on developing adequate culture supplements devoid of animal-derived products. In the present study, we have investigated the feasibility of umbilical cord blood-platelet lysate (UCB-PL) as a standard substitute for fetal bovine serum (FBS) and human peripheral blood-PL (PB-PL). In this experimental study, platelet concentrates (PC) from UCB and human PB donors were frozen, melted, and sterilized to obtain PL. Quality control included platelet cell counts, sterility testing (viral and microbial), total protein concentrations, growth factor levels, and PL stability. The effects of UCB-PL and PB-PL on hMSCs proliferation and differentiation into osteocytes, chondrocytes, and adipocytes were studied and the results compared with FBS. UCB-PL contained high levels of protein content, platelet-derived growth factor- AB (PDGF-AB), and transforming growth factor (TGF) compared to PB-PL. All growth factors were stable for at least nine months post-storage at -70˚C. hMSCs proliferation enhanced following treatment with UCB-PL. With all three supplements, hMSCs could differentiate into all three lineages. PB-PL and UCB-PL both were potent in hMSCs proliferation. However, PB promoted osteoblastic differentiation and UCB-PL induced chondrogenic differentiation. Because of availability, ease of use and feasible standardization of UCB-PL, we have suggested that UCB-PL be used as an alternative to FBS and PB-PL for the cultivation and expansion of hMSCs in cellular therapy.

    To investigate hematological and serum protein profiles of cadaveric heart blood with regard to the cause of death, serial forensic autopsy cases (n=308, >18 years of age, within 48 h postmortem) were examined. Red blood cells (Rbc), hemoglobin (Hb), platelets (Plt), white blood cells (Wbc), total protein (TP) and albumin (Alb) were examined in bilateral cardiac blood. Blood cell counts, collected after turning the bodies at autopsy, approximated to the clinical values. Postmortem changes were not significant for these markers. In non-head blunt injury cases, Rbc counts, Hb, TP and Alb levels in bilateral cardiac blood were lower in subacute deaths (survival time, 1-12 h) than in acute deaths (survival time hematology analyzer than by using a blood smear test, suggesting Rbc fragmentation caused by deep burns, while increases in Wbc count and decreases in Alb levels were seen for subacute deaths. For asphyxiation, Rbc count, Hb, TP and Alb levels in bilateral cardiac blood were higher than other groups, and TP and Alb levels in the right cardiac blood were higher for hanging than for strangulation. These findings suggest that analyses of blood cells and proteins are useful for investigating the cause of death.

    Full Text Available Multiple sclerosis (MS is a disease involving oxidative stress (OS. This study was aimed at examination of the effect of melatonin supplementation on OS parameters, especially oxidative protein modifications of blood serum proteins, in MS patients. The study included 11 control subjects, 14 de novo diagnosed MS patients with the relapsing-remitting form of MS (RRMS, 36 patients with RRMS receiving interferon beta-1b (250 μg every other day, and 25 RRMS patients receiving interferon beta-1b plus melatonin (5 mg daily. The levels of N′-formylkynurenine, kynurenine, dityrosine, carbonyl groups, advanced glycation products (AGEs, advanced oxidation protein products (AOPP, and malondialdehyde were elevated in nontreated RRSM patients. N′-Formylkynurenine, kynurenine, AGEs, and carbonyl contents were decreased only in the group treated with interferon beta plus melatonin, while dityrosine and AOPP contents were decreased both in the group of patients treated with interferon beta and in the group treated with interferon beta-1b plus melatonin. These results demonstrate that melatonin ameliorates OS in MS patients supporting the view that combined administration of interferon beta-1b and melatonin can be more effective in reducing OS in MS patients than interferon beta-1b alone.

    Genalyte has developed a multiplex silicon photonic chip diagnostics platform (MaverickTM) for rapid detection of up to 32 biological analytes from a drop of sample in just 10 to 20 minutes. The chips are manufactured with waveguides adjacent to ring resonators, and probed with a continuously variable wavelength laser. A shift in the resonant wavelength as mass binds above the ring resonators is measured and is directly proportional to the amount of bound macromolecules. We present here the ability to multiplex the detection of hemorrhagic fever antigens in whole blood, serum, and saliva in a 16 minute assay. Our proof of concept testing of a multiplex antigencapture chip has the ability to detect Zaire Ebola (ZEBOV) recombinant soluble glycoprotein (rsGP), Marburg virus (MARV) Angola recombinant glycoprotein (rGP) and dengue nonstructural protein I (NS1). In parallel, detection of 2 malaria antigens has proven successful, but has yet to be incorporated into multiplex with the others. Each assay performs with sensitivity ranging from 1.6 ng/ml to 39 ng/ml depending on the antigen detected, and with minimal cross-reactivity.

    Full Text Available Human serum albumin (HSA is extensively used in clinics to treat a variety of diseases, such as hypoproteinemia, hemorrhagic shock, serious burn injuries, cirrhotic ascites and fetal erythroblastosis. To address supply shortages and high safety risks from limited human donors, we recently developed recombinant technology to produce HSA from rice endosperm. To assess the risk potential of HSA derived from Oryza sativa (OsrHSA before a First-in-human (FIH trial, we compared OsrHSA and plasma-derived HSA (pHSA, evaluating the potential for an immune reaction and toxicity using human peripheral blood mononuclear cells (PBMCs. The results indicated that neither OsrHSA nor pHSA stimulated T cell proliferation at 1x and 5x dosages. We also found no significant differences in the profiles of the CD4(+ and CD8(+ T cell subsets between OsrHSA- and pHSA-treated cells. Furthermore, the results showed that there were no significant differences between OsrHSA and pHSA in the production of cytokines such as interferon-gamma (IFN-γ, tumor necrosis factor-alpha (TNF-α, interleukin (IL-10 and IL-4. Our results demonstrated that OsrHSA has equivalent immunotoxicity to pHSA when using the PBMC model. Moreover, this ex vivo system could provide an alternative approach to predict potential risks in novel biopharmaceutical development.

    Circulating Anodic Antigen (CAA) testing is a powerful, increasingly-used tool for diagnosis of active schistosome infection. We sought to determine the feasibility and reliability of measuring CAA in blood spots collected on Whatman 903 Protein Saver cards, which are the predominant filter papers used worldwide for dried blood spot (DBS) research and clinical care. CAA was eluted from blood spots collected from 19 individuals onto Whatman 903 cards in Mwanza, Tanzania, and the assay was optimized to achieve CAA ratios comparable to those obtained from the spots’ corresponding serum samples. The optimized assay was then used to determine the correlation of serum samples (n=16) with DBS from cards that had been stored for 8 years at ambient temperature.Using a DBS volume equivalent to approximately four times the quantity of serum, CAA testing in DBS had a sensitivity of 76% and a specificity of 79% compared to CAA testing in serum. CAA testing was reliable in samples eluted from Whatman 903 cards that had been stored for 8 years at ambient temperature. The overall kappa coefficient was 0.53 (standard error 0.17, p<0.001). We conclude that CAA can be reliably and accurately measured in DBS collected onto the filter paper that is most commonly used for clinical care and research, and that can be stored for prolonged periods of time. This finding opens new avenues for future work among more than 700 million individuals living in areas worldwide in which schistosomes are endemic. PMID:26149541

    The aim of this work was to estimate the efficacy and safety of single intramuscular introduction of specific heterologous immunoglobulin as prophylactic drug against Ebola hemorrhagic fever. Materials and methods. The specific heterologous immunoglobulin was introduced as a special prophylactic drug to 28 patients in epidemic situations, after skin hurt with infectious materials or contact with infectious blood. Clinico-laboratory observation was performed in 24 subjects after single intramuscular introduction of heterologous immunoglobulin Ebola. The samples of blood serum were investigated for immunoglobulin Ebola and antibodies to horse gamma-globulin on the 30th and 60th days after prophylaxis. Results. None of the subjects of the study contracted Ebola fever. There were no anaphylactic reactions after special prophylaxis with specific heterologous immunoglobulin. Among the subjects with normal allergic state 31% responded with local reactions; 13%, with a general reaction (mild case of the serum disease). Almost no reaction was observed in patients with unfavorable allergic state subjected to desensitizing therapy; in the absence of desensitizing therapy, 50% of patients with unfavorable allergic state exhibited local reactions; 17%, mild cases of the serum disease; 33%, moderate cases of the serum disease. In summary, if the tactics of immunoglobulin application was right, the quantity of local allergic reactions was 28%; of wide spread reactions, 6%. Weak serum disease was observed in 11% of the subjects. The prognostic period of resistance to Ebola fever was less than 30 days. Conclusion. The prophylactic use of specific immunoglobulin from horse blood serum against hemorrhagic Ebola fever is effective and relatively safe in patients subjected to desensitizing therapy.

    The determination of trace elements and electrolyte concentrations in blood serum, hair and fingernails of 16 patients with Crohn's disease was carried out by means of instrumental neutron activation analysis. In the serum a significant decline in the zinc content could be registered, while the remaining trace elements remained in the normal range. The parenteral nutrition also showed a zinc deficiency. There was, however, also an iron deficiency. The studies of the hair and fingernails gave the following results: Rubidium and antimony in the normal range; zinc, selenium, iron and cobalt below normal values. (orig./PW) [de

    The characteristics of people whose serum cholesterol level is unusually susceptible to consumption of cholesterol were investigated. Thirty-two volunteers from the general population of Wageningen, the Netherlands, each participated in three controlled dietary trials in 1982. A low-cholesterol diet was fed during the first half and a high-cholesterol diet during the second half of each trial, and the change (response) of serum cholesterol was measured. The responses in the three trials were averaged to give each subject's mean responsiveness. Fecal excretion of cholesterol and its metabolites were measured in the second trial, and body cholesterol synthesis was calculated. Responsiveness showed a positive correlation with serum high density lipoprotein2 (HDL2) cholesterol (r = 0.41, p less than 0.05) and with serum total cholesterol level on a high-cholesterol diet (r = 0.31, p = 0.09). A negative relation was found with habitual cholesterol consumption (r = -0.62, p less than 0.01), with body mass index (r = -0.50, p less than 0.01), and with the rate of endogenous cholesterol synthesis (r = -0.40, p less than 0.05), but not with the reaction of endogenous cholesterol synthesis rate to an increased intake of cholesterol. No relation was found with age, sex, total caloric needs, or the ratio of primary to secondary fecal steroids. Upon multiple regression analysis, only habitual cholesterol intake and serum total and HDL2 cholesterol levels contributed significantly to the explanation of variance in responsiveness. Thus, a low habitual cholesterol intake, a high serum HDL2 cholesterol level, or a low body weight do not make one less susceptible to dietary cholesterol-induced hypercholesterolemia.

    Full Text Available BACKGROUND/OBJECTIVE: Gene-gene interactions in the reverse cholesterol transport system for high-density lipoprotein-cholesterol (HDL-C are poorly understood. The present study observed gene-gene combination effect and interactions between single nucleotide polymorphisms (SNPs in ABCA1, APOA1, SR-B1, and CETP in serum HDL-C from a cross-sectional study in the Japanese population. METHODS: The study population comprised 1,535 men and 1,515 women aged 35-69 years who were enrolled in the Japan Multi-Institutional Collaborative Cohort (J-MICC Study. We selected 13 SNPs in the ABCA1, APOA1, CETP, and SR-B1 genes in the reverse cholesterol transport system. The effects of genetic and environmental factors were assessed using general linear and logistic regression models after adjusting for age, sex, and region. PRINCIPAL FINDINGS: Alcohol consumption and daily activity were positively associated with HDL-C levels, whereas smoking had a negative relationship. The T allele of CETP, rs3764261, was correlated with higher HDL-C levels and had the highest coefficient (2.93 mg/dL/allele among the 13 SNPs, which was statistically significant after applying the Bonferroni correction (p<0.001. Gene-gene combination analysis revealed that CETP rs3764261 was associated with high HDL-C levels with any combination of SNPs from ABCA1, APOA1, and SR-B1, although no gene-gene interaction was apparent. An increasing trend for serum HDL-C was also observed with an increasing number of alleles (p<0.001. CONCLUSIONS: The present study identified a multiplier effect from a polymorphism in CETP with ABCA1, APOA1, and SR-B1, as well as a dose-dependence according to the number of alleles present.

    The performance of a real-time PCR-based assay was retrospectively analyzed (according to European Organization for Research and Treatment of Cancer/Mycosis Study Group criteria) in the samples of patients with invasive aspergillosis. A total of 711 serial samples (356 whole-blood and 355 serum samples) from 38 adult patients were analyzed. The Aspergillus fumigatus PCR assay results were positive for 89 of 356 (25%) whole-blood samples and 90 of 355 (25.35%) serum samples. Positive PCR results were seen in 29 of 31 (93.5%) patients for which serum was analyzed and in 31 of 33 (93.9%) cases with whole-blood specimens. Both blood and serum samples were available in 26 cases, and significant differences were not observed in this subgroup of cases. The average number of threshold cycles (C(T)) for positive blood samples was 37.6, and the average C(T) for serum was 37.4. The DNA concentration ranged between 2 and 50 fg per μl of sample, with average DNA concentrations of 10.2 and 11.7 fg in positive blood and serum samples, respectively (P > 0.01). The performance of this PCR-based quantitative assay was similar for both serum and blood samples. We recommend serum samples as the most convenient hematological sample to use for Aspergillus DNA quantification when serial determinations are done.

    It was studied that cancer-causing processes are related with the disproportions of essential and toxic elements in body tissues and fluid. The purpose of the current study was to evaluate the levels of magnesium (Mg) and cadmium (Cd) in serum and blood samples of smokers and nonsmokers who have chronic myeloid (CML) and lymphocytic (CLL) leukemia, age ranged 31-50 years. For comparative study, age-matched smokers and nonsmoker males were chosen as controls/referents. The levels of elements in patient were analyzed before any treatment by atomic absorption spectrophotometer, after microwave assisted acid digestion. The validation of the method was done by using certified reference materials of serum and blood samples. The resulted data indicated that the adult male smokers and nonsmokers have two- to fourfold higher levels of Cd in the blood and sera samples as compared to the referents (p blood and serum samples of both types of leukemia patients as related to referent values. The resulted data indicates significant negative correlation among Mg and Cd in leukemia patients and smoker referents. Further studies are needed to clarify the role of these elements in pathogenesis of chronic leukemia.

    Full Text Available To investigate the effects of daily supplementation with docosahexaenoic acid (DHA on coronary heart disease risks in 38 middle-aged men with hypertension and/or hypercholesterolemia in Scotland, a five-week double-blind placebo-controlled dietary supplementation with either 2 g of DHA or active placebo (1 g of olive oil was conducted. Percent composition of DHA in plasma phospholipids increased significantly in DHA group. Systolic and diastolic blood pressure and heart rate decreased significantly in DHA group, but not in placebo group. High-density lipoprotein cholesterol (HDL-C increased significantly, and total cholesterol (TC/HDL-C and non-HDL-C/HDL-C ratios decreased significantly in both groups. There was no change in TC and non-HDL-C. We conclude that 2 g/day of DHA supplementation reduced coronary heart disease risk factor level improving blood pressure, heart rate, and lipid profiles in hypertensive, hypercholesterolemic Scottish men who do not eat fish on a regular basis.

  11. Detection of IL28B SNP DNA from buccal epithelial cells, small amounts of serum, and dried blood spots.

    Directory of Open Access Journals (Sweden)

    Philippe Halfon

    Full Text Available BACKGROUND & AIMS: Point mutations in the coding region of the interleukin 28 gene (rs12979860 have recently been identified for predicting the outcome of treatment of hepatitis C virus infection. This polymorphism detection was based on whole blood DNA extraction. Alternatively, DNA for genetic diagnosis has been derived from buccal epithelial cells (BEC, dried blood spots (DBS, and genomic DNA from serum. The aim of the study was to investigate the reliability and accuracy of alternative routes of testing for single nucleotide polymorphism allele rs12979860CC. METHODS: Blood, plasma, and sera samples from 200 patients were extracted (400 µL. Buccal smears were tested using an FTA card. To simulate postal delay, we tested the influence of storage at ambient temperature on the different sources of DNA at five time points (baseline, 48 h, 6 days, 9 days, and 12 days. RESULTS: There was 100% concordance between blood, plasma, sera, and BEC, validating the use of DNA extracted from BEC collected on cytology brushes for genetic testing. Genetic variations in HPTR1 gene were detected using smear technique in blood smear (3620 copies as well as in buccal smears (5870 copies. These results are similar to those for whole blood diluted at 1/10. A minimum of 0.04 µL, 4 µL, and 40 µL was necessary to obtain exploitable results respectively for whole blood, sera, and plasma. No significant variation between each time point was observed for the different sources of DNA. IL28B SNPs analysis at these different time points showed the same results using the four sources of DNA. CONCLUSION: We demonstrated that genomic DNA extraction from buccal cells, small amounts of serum, and dried blood spots is an alternative to DNA extracted from peripheral blood cells and is helpful in retrospective and prospective studies for multiple genetic markers, specifically in hard-to-reach individuals.

    2012-06-01

    Full Text Available To investigate uterine and serum Ca++ and Mg++ variations during the estrous cycle in the bovine, 66 genital tracts and blood samples were collected from Urmia abattoir, Urmia, Iran. The phase of the estrous cycle was determined by examination of the structures present on ovaries and uterine tonicity. Of the collected samples, 17 were pro-estrus, 12 estrus, 14 metestrus and 23 diestrus. The uterine fluid was collected by gentle scraping of the uterine mucosa with a curette. The mean ± SEM concentration of serum Ca++ in pro-estrus, estrus, metestrus and diestrus was 5.77 ± 0.69, 8.87 ± 1.83, 10.95 ± 1.52, 11.09 ± 1.08 mg dL-1, and the mean concentration of uterine fluid Ca++ was 4.40 ± 0.72, 3.15 ± 0.67, 5.89 ± 0.88, 8.63 ± 0.97 mg dL-1, respectively. The mean concentration of serum Mg++ in pro-estrus, estrus, metestrus and diestrus was 3.53 ± 0.30, 4.20 ± 0.52, 3.49 ± 0.38, 3.39 ± 0.29 mg dL-1, and mean concentration of uterine fluid Mg++ was 5.27 ± 0.42, 4.92 ± 0.60, 5.56 ± 0.30, 5.88 ± 0.36 mg dL-1, respectively. The serum and uterine fluid Ca++ in pro-estrus were significantly different from those of the metestrus and diestrus. In all stages of estrous cycle the mean concentration of serum Ca++ was higher than that in the uterine fluid. The difference between serum and uterine fluid Ca++ in estrus, metestrus and diestrus was significant. There was no significant difference between serum Mg++ content nor was it different from uterine fluid Mg++ content at any stages of estrous cycle. In all stages of estrous cycle the uterine fluid Mg++ was higher than that of the serum. These results suggest that during the estrous cycle in the cow, Ca++ is passively secreted in uterine fluids and is mostly dependent on blood serum Ca++ variations but Mg++ is secreted independently and does not follow variations in the serum concentrations.
