    Chronic inflammation associated with inflammatory bowel disease (IBD) results in increased oxidative stress that damages the colonic microenvironment. Low levels of serum bilirubin, an endogenous antioxidant, have been associated with increased risk for Crohn’s disease (CD). Therefore, the aim of this study was to examine whether total serum bilirubin levels are associated with ulcerative colitis (UC). We identified a retrospective case-control population (n = 6,649) from a single tertiary care center, Penn State Hershey Medical Center (PSU) and a validation cohort (n = 1,996) from Virginia Commonwealth University Medical Center (VCU). Cases were age- and sex-matched to controls (PSU: CD n = 254, UC n = 187; VCU: CD n = 233, UC n = 124). Total serum bilirubin levels were obtained from de-identified medical records and segregated into quartiles. Logistic regression analysis was performed on each quartile of total serum bilirubin compared to the last quartile (highest bilirubin levels) to determine the association of total serum bilirubin with UC. Similar to CD patients, UC patients demonstrated reduced levels of total serum bilirubin compared to controls at PSU and VCU. The lowest quartile of total serum bilirubin was independently associated with UC for the PSU (OR: 1.98 [95% CI: 1.09–3.63]) and VCU cohorts (OR: 6.07 [95% CI: 3.01–12.75]). Lower levels of the antioxidant bilirubin may reduce the capability of UC patients to remove reactive oxygen species leading to an increase in intestinal injury. Therapeutics that reduce oxidative stress may be beneficial for these patients. PMID:28594959

    To determine whether high serum bilirubin concentrations interfere with the measurement of serum total protein concentration by refractometry and to assess potential biases among refractometer measurements. Evaluation study. Sera from 2 healthy Greyhounds. Bilirubin was dissolved in 0.1M NaOH, and the resulting solution was mixed with sera from 2 dogs from which food had been withheld to achieve various bilirubin concentrations up to 40 mg/dL. Refractometric total protein concentrations were estimated with 3 clinical refractometers. A biochemical analyzer was used to measure biuret assay-based total protein and bilirubin concentrations with spectrophotometric assays. No interference with refractometric measurement of total protein concentrations was detected with bilirubin concentrations up to 41.5 mg/dL. Biases in refractometric total protein concentrations were detected and were related to the conversion of refractive index values to total protein concentrations. Hyperbilirubinemia did not interfere with the refractometric estimation of serum total protein concentration. The agreement among total protein concentrations estimated by 3 refractometers was dependent on the method of conversion of refractive index to total protein concentration and was independent of hyperbilirubinemia.

    Our previous studies showed that serum calcium level may have influence in the blood pressure to older male subjects, but the relationship between serum calcium level and blood lipids is unclear. The aim of this study was to evaluate the relationship between total serum calcium level and blood lipids. In our study, total serum calcium level and blood lipids were measured among 1,075 subjects, with age range of 30-60 years, who were recruited for the routine health screening in 2006. The results showed that serum calcium level was positively correlated with triglyceride and total cholesterol weight, but not HDL-cholesterol and LDL-cholesterol in female subjects (P 0.05). These findings suggest that a higher total serum calcium level may have a adverse effects on serum cholesterol and triglycerides among female subjects.

    Full Text Available INTRODUCTION: Surveillance for risk factors of heart diseases, like increased blood sugar, cholesterol becomes difficult in places with inadequate lab facilities due to difficulty in sample collection, transportation and processing. Feasibility of using dried blood/seru m spots in such situations can be thought of as an alternative to fresh serum total cholesterol, as sample collection does not require much expertise. AIM: The aim of this study is to determine whether dried blood and serum spots can be used as an alternat ive to fresh serum for estimation of total cholesterol in field studies. METHOD S : Fresh serum from 100 subjects selected randomly was used for estimation of total cholesterol. Four spots each of blood and serum from these samples were made on Whatman paper 3, out of which one spot from each were analysed on the day of collection and rest were kept in resealable bags to be analysed on day 7, 15 and 30. The correlation between the dried blood/serum spot values with the fresh serum total cholesterol values was examined. RESULTS: A significant correlation with fresh serum total cholesterol values (p value<0.01 was seen for dried serum spots stored up to day 30(0.747 to 0.942 and for dried blood spots stored up to day 15(0.598 to 0.949. CONCLUSIONS: Total chol esterol estimated by dried blood spot up to 15 days and dried serum spots stored up to 30 days can be considered as an alternative to fresh serum for estimation of serum total cholesterol.

    Full Text Available Kernicterus (bilirubin induced encephalopathy is an uncommon disorder with tragic consequences, especially when it affects healthy term and near-term neonates. Appointment of cut off value of total serum bilirubin level that have a safe margin for early prompt treatment, as a result, prevention of kernicterus. In our study, all of icteric neonates that admitted in our center in 1 year were enrolled. From 305 neonates, 25 cases have kernicterus manifestations. These 25 neonates have not any conditions that mimic kernicterus manifestations (such as birth trauma, intra cranial hemorrhage, asphyxia. We divided neonates to 2major groups: neonates 8 days-old. Also these cases were divided to high-risk and low-risk neonates. In this study, 220 neonates (72.1% were ≤ 7days and 85 neonates (27.9% were > 8 days-old. Also 109 neonates (35.7% were or with risk factors and 196 neonates (64.3% were or without risk factors. Risk factors were prematurity, acidosis, hemolysis, duration of hyperbilirubinemia, sepsis and respiratory distress. Cutoff value of bilirubin level for neonates ≤ 7 days was 25.15 mg/dl and for neonates > 8 days was 22.25 mg/dl that no statistically significant difference was found. Cut off value of bilirubin level for high-risk neonates was 22.35 mg/dl and for low-risk neonates was 27.95 mg/dl that statistically significant difference was found. The lower limit of bilirubin in neonates with kernicterus was 16.5 mg/dl and the upper limit was 44 mg/dl. The high-risk neonates need prompt treatment of hyperbilirubinemia at lower levels of total bilirubin compared with low-risk neonates.

    This study aimed to assess serum total alkaline phosphatase (ALP) and its bone isoform (BALP) levels during the ageing and in different physiologic states of sheep, in order to expand the knowledge about the variation of these biomarkers over the sheep lifespan. Ninety female sheep were divided into nine groups of various ages and physiological states (dry, lactation and pregnancy). Serum ALP, BALP and mineral levels were determined by commercial immunoassay, molecular absorbance spectrophotometry and chemical luminescence for BALP determination. Serum ALP and BALP decreased as sheep aged, and no statistically significant differences were obtained between ewes in different physiologic states. The continuous decline of serum BALP concentration along the sheep lifespan, namely in mature and old sheep, is a sign of decreasing bone turnover associated with ageing. Serum calcium concentrations increased slightly until 2 years of age and then showed a tenuous but statistically significant decrease in mature sheep, while serum phosphorus maintained an uninterrupted decrease as sheep matured. The knowledge of serum values of bone biomarkers throughout the sheep lifespan may be useful in preclinical orthopaedic research studies and for animal science studies using sheep.

    In this study, the serum triglycerides and total serum cholesterol levels in patients with rotator cuff tear were determined. Frequency-matched case-control study. Setting University teaching hospital. 240 individuals who were operated on at our institution were included in the study. 120 patients (45 men and 75 women; mean age 64.86 years, range 40 to 83 years) who underwent arthroscopic repair of a rotator cuff tear were included in group 1. 120 patients (45 men and 75 women; mean age 63.91 years, range 38 to 78 years) who underwent arthroscopic meniscectomy for a meniscal tear and had no evidence of shoulder pathology were included in group 2 (control group). These patients were frequency-matched by age (within 3 years) and sex with patients of group 1. Measurement of serum triglyceride and total cholesterol concentrations. When comparing the two groups, there was no difference either in serum triglyceride concentration or total serum cholesterol concentration. There appears to be no association between serum triglyceride concentration and total serum cholesterol concentration in rotator cuff tears.

    Observational epidemiological evidence supports a linear inverse and independent association between serum total bilirubin levels and coronary heart disease (CHD) risk, but whether this association is causal remains to be ascertained. A Mendelian randomization approach was employed to test whether serum total bilirubin is causally linked to CHD. The genetic variant rs6742078--well known to specifically modify levels of serum total bilirubin and accounting for up to 20% of the variance in circulating serum total bilirubin levels--was used as an instrumental variable. In pooled analysis of estimates reported from published genome-wide association studies, every copy of the T allele of rs6742078 was associated with 0.42 standard deviation (SD) higher levels of serum total bilirubin (95% confidence interval, 0.40 to 0.43). Based on combined data from the Coronary Artery Disease Genome wide Replication and Meta-analyses and the Coronary Artery Disease (C4D) Genetics Consortium involving a total of 36,763 CHD cases and 76,997 controls, the odds ratio for CHD per copy of the T allele was 1.01 (95% confidence interval, 0.99 to 1.04). The odds ratio of CHD for a 1 SD genetically elevated serum total bilirubin level was 1.03 (95% confidence interval, 0.98 to 1.09). The current findings casts doubt on a strong causal association of serum total bilirubin levels with CHD. The inverse associations demonstrated in observational studies may be driven by biases such as unmeasured confounding and/or reverse causation. However, further research in large-scale consortia is needed.

    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.

    Full Text Available The aim of the present study was to compare, during the pollen season, serum levels of total IgE and soluble CD23 (sCD23 from patients with allergic bronchial asthma, with those from healthy subjects. Significantly higher levels of total IgE and sCD23 were found in patients with asthma compared to the control group. Both in normal controls and in asthmatic patients, a significant correlation was shown between the levels of these two molecules. In asthmatic patients, significant correlations were found for both total IgE and sCD23, with lung function measured as bronchial responsiveness to inhaled methacholine. These results suggest that in asthmatic patients, in addition to the study of total serum IgE levels, the assessment of sCD23 serum levels may be helpful in the evaluation of disease activity.

    To determine the diagnostic accuracy of serum iron and total iron binding capacity (TIBC) in detection of iron deficiency. Descriptive, analytical study. Department of Chemical Pathology and Endocrinology, from January 2013 to October 2015. Data of 1,815 patients with results of serum iron, TIBC and ferritin from January 2013 to October 2015 was retrieved from Laboratory information System (LIMS) of AFIP. Diagnostic Accuracy Studies (STARD) guidelines were followed. Subjects of either gender, aged 1 - 68 years were included. Cases with raised serum ferritin levels (male > 336 ng/ml, female > 307 ng/ml) were excluded. Serum Ferritin was taken as gold standard with specificity of 99% and sensitivity of 80% at concentration of 30 ng/ml. Transferrin saturation was determined by dividing serum iron by TIBC and multiplying by 100. Out of 1,815 subjects, 931 (51.29%) were males and 884 (48.71%) were females. The median age of the patients were 29.1 years (Inter-quartile range, IQR 19.1). Taking ferritin as gold standard, the sensitivity and specificity of serum iron was 63.5% and 38.6%, respectively; while that of TIBC was 64.5 % and 42.8%, respectively. Ferritin showed poor correlation with iron, TIBC and transferrin saturation. Serum iron and TIBC give no additional information in the diagnosis of iron deficiency anemia and these tests are redundant for the diagnosis of iron deficiency state, if serum ferritin is available.

    Determination of serum total protein concentration is commonly performed by the biuret method. Refractometric measurement is a faster and less expensive alternative but its accuracy has not been determined in ruminants. The purpose of the study was to compare the serum total protein concentrations in cattle, sheep, and goats measured by the biuret method with those obtained by refractometry. Serum total protein concentration was determined in 120 cattle, 67 sheep, and 58 goat blood samples refractometrically and with the biuret method. The data were analyzed with a paired samples t-test, and Passing and Bablok regression equations and Bland and Altman plots were generated. There was a strong linear relationship between the total protein values determined with the refractometer and the biuret method in cattle, sheep, and goats. The statistical accuracy, which represents a bias correction factor that measures the deviation of the best-fit line from the 45° line through the origin, was 90.63% for cattle, 93.05% for sheep, and 91.76% for goats. The mean protein values determined with the refractometer were significantly lower than those measured with the biuret method in cattle and goats (P  .05). The evaluated refractometer was sufficiently accurate for the determination of serum total proteins in cattle, sheep, and goats, although it cannot be used interchangeably with the biuret method. The RIs should be corrected for negative bias based on the created equations. © 2017 American Society for Veterinary Clinical Pathology.

    Vincenzo Rochira

    Full Text Available BACKGROUND: Testosterone (T deficiency remains a poorly understood issue in men with Human Immunodeficiency Virus (HIV. We investigated the gonadal status in HIV-infected men in order to characterize T deficiency and to identify predictive factors for low serum T. METHODOLOGY/PRINCIPAL FINDINGS: We performed a cross-sectional, observational study on 1325 consecutive HIV male outpatients, most of them having lipodystrophy. Serum total T<300 ng/dL was used as the threshold for biochemical T deficiency. Morning serum total T, luteinizing hormone (LH, estradiol, HIV parameters, and body composition parameters by CT-scan and Dual-Energy-X-ray-Absorptiometry were measured in each case. Sexual behavior was evaluated in a subset of 247 patients. T deficiency was found in 212 subjects, especially in the age range 40-59, but was frequent even in younger patients. T deficiency occurred mainly in association with low/normal serum LH. Adiposity was higher in subjects with T deficiency (p<0.0001 and both visceral adipose tissue and body mass index were the main negative predictors of serum total T. Osteoporosis and erectile dysfunction were present in a similar percentage in men with or without T deficiency. CONCLUSIONS/SIGNIFICANCE: Premature decline of serum T is common (16% among young/middle-aged HIV-infected men and is associated with inappropriately low/normal LH and increased visceral fat. T deficiency occurs at a young age and may be considered an element of the process of premature or accelerated aging known to be associated with HIV infection. The role of HIV and/or HIV infection treatments, as well as the role of the general health state on the gonadal axis, remains, in fact, to be elucidated. Due to the low specificity of signs and symptoms of hypogonadism in the context of HIV, caution is needed in the diagnosis of hypogonadism in HIV-infected men with biochemical low serum T levels.

    Elevation in the total sialic acid (TSA), TSA/total protein (TSA/TP) and lipid-bound sialic acid (LASA) concentration in serum occurs in breast cancer and we have studied the applicability of the assays in classification of undefined breast tumors. Sialic acid was determined by HPLC and the statistical evaluation included the receiver operating characteristic (ROC) and Youden's index analyses. In cancer patients, the serum LASA and TSA concentration was significantly higher (p breast cancer and benign breast disease and at the specificity level of 0.95 the corresponding sensitivities were 0.32 (TSA), 0.14 (TSA/TP) and 0.23 (LASA). The results indicate that both breast cancer and benign breast disease cause elevation of TSA, TSA/TP and LASA values in serum and do not provide reliable classification of undefined breast tumors.

    It is well known that paraoxonase-1 (PON1) activity may decrease during the course of infection and inflammation. The aim of this study was to investigate serum PON1 activity, oxidative status, and thiols levels in patients with acute brucellosis. In addition, we investigated the PON1 phenotype in patients with acute brucellosis. Thirty patients with acute brucellosis and 35 healthy controls were enrolled. Serum paraoxonase and arylesterase activities, thiols levels, lipid hydroperoxide levels, total antioxidant capacity (TAC), total oxidant status (TOS) and oxidative stress index (OSI) were determined. Serum basal and salt-stimulated paraoxonase-arylesterase activities, TAC levels and thiols levels were significantly lower in patients with acute brucellosis than controls (for all, p brucellosis. These results indicate that lower PON1 activity is associated with oxidant-antioxidant imbalance.

    Unbound serum gold (UBSG) has received little attention, possibly because of rapid in vivo decay and in vivo concentration below the range of existing analytical procedures. We have recently developed a methodology enabling quantitation and study of UBSG during chrysotherapy to assess effects on cellular functions. UBSG after gold administration is labile, declining rapidly after attaining peak values at which lymphocyte mitogen response and polymorphonuclear phagocytosis were observed to be suppressed. Oral gold, i.e., auranofin, 3 mg BID as compared to systemic chrysotherapy 50 mg/wk, resulted in a higher percentage of UBSG to total serum gold.

    Diagnosis of cholangiocarcinoma (CCA) is difficult when patients do not show jaundice. The aim of this study was to examine the feasibility of using the total serum bile acid (TSBA) level as an aid for the diagnosis of CCA in patients without jaundice. For this purpose, TSBA of the following groups were measured using a Beckman Synchron CX4 clinical chemistry analyzer: 60 cases of CCA with total serum bilirubin ≤2 mg/dL (low total bilirubin group, LTB); 32 cases of CCA with total serum bilirubin >2 mg/dL (high total bilirubin group, HTB); and 115 healthy controls. Liver function parameters such as serum cholesterol, albumin, alanine aminotransferase (ALT), aspartate aminotransferase (AST) and alkaline phosphatase (ALP) were also examined. The results showed that the TSBA of both LTB and HTB groups of the CCA patients were significantly higher than that of the healthy controls. Also, significant correlation was observed between TSBA and total bilirubin levels in the HTB group of CCA patients. However, no such correlation was seen in the LTB group. The cut-off value of TSBA was determined for the LTB group of CCA patients using the receiver operating characteristic curve analysis, and it was 6.05 μmol/L with the sensitivity and specificity of 46.7% and 84.4%, respectively. In addition, the ALP level was correlated well with the TSBA level and ALP in HTB group was significantly higher than that of LTB group. Moreover, the combination of high TSBA and high ALP levels gave higher specificity up to 97.4%. TSBA might be useful for the diagnosis of CCA patients without jaundice.

    Full Text Available Background: Pre-eclampsia is characterized by hypertension development and proteinuria during pregnancy. Hypertension disorder is a leading cause of maternal and fetal morbidity and death in worldwide. Although the pathophysiology of hypertension during pregnancy is unclear, but there is consensus that early diagnosis and aggressive treatment is warranted to prevent complicated to both fetus and mother. The changes of serum trace elements during pregnancy are paramount important to predict and good understanding the situation of patients. The aim of this study was about this issue. Materials and Methods: In a case-control study we investigated the possible differences in the level of serum calcium, phosphorus and total protein in 55 healthy pregnant and 52 pregnant with hypertensive disease at 32-40 weeks of gestational age during the recent two years in Loghman hospital of Tehran. Some information such as age, blood group, parity number and blood pressure was taken from patients by a questionnaire. Results: The case population consisted of 22 sever preeclampsia, 15 mild preeclampsia, 8 eclampsia, and 7 chronic hypertensive. The mean serum calcium concentration (mg/dl was 9.180.74 in control group, 8.810.9 in mild preeclampsia, 7.850.38 in sever preeclampsia, 7.83 0.47 in eclampsia, 8.91 0.3 in chronic blood pressure. The mean serum phosphorus (mg/dl level observed, 4.27 in sever preeclampsia, 3.74 in eclampsia, 3.59 in mild eclampsia, 4.09 in chronic blood pressure, and 3.43 in control pregnant women. The mean serum total protein concentration level in sever preeclampsia and eclampsia was 5.46 and 5.04 mg/dl respectively. Conclusion: In conclusion, sever preeclampsia and eclampsia are associated with decreased level of calcium, total protein, and increased concentration of phosphorus.

    Full Text Available The purpose of this study was to determine the concentrations of cobalt, chromium, and molybdenum in the serum of paediatric tumour patients after fixed hinge total knee arthroplasty. Further, these metal ion levels were compared with serum metal ion levels of patients with other orthopaedic devices such as hip and knee prostheses with metal-on-metal or metal-on-polyethylene articulation to find differences between anatomical locations, abrasion characteristics, and bearing surfaces. After an average follow-up of 108 months (range: 67 to 163 of 11 paediatric patients with fixed hinge total knee arthroplasty, the mean concentrations for Co and Cr were significantly increased while Mo was within the limits compared to the upper values from the reference laboratory. Furthermore, these serum concentrations were significantly higher compared to patients with a standard rotating hinge device (P=0.002 and P<0.001 and preoperative controls (P<0.001. On the other hand, the serum levels of patients following MoM THA or rotating hinge arthroplasty using megaprostheses were higher. Therefore, periodic long-term follow-ups are recommended due to the rising concerns about systemic metal ion exposure in the literature. Upon the occurrence of adverse reactions to metal debris the revision of the fixed hinge implant should be considered.

    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{sub 4}), indicating the presence of hypothyroidism. After administration of levothyroxine Na, their fT{sub 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.

    Oxidative stress has been shown to play an important role in the pathogenesis of post-traumatic stress disorder (PTSD). Although there are some studies on oxidative stress and PTSD, there is no report available on the serum total oxidant and antioxidant status in earthquake survivors with PTSD. Therefore, this study aimed to investigate the serum total oxidant and antioxidant status in earthquake survivors with chronic PTSD. The study group included 45 earthquake survivors with PTSD and 40 earthquake survivors without PTSD. The oxidative status was determined using the total antioxidant status and total oxidant status (TOS) measurements and by calculating the oxidative stress index (OSI). There were no statistically significant differences in the total antioxidant status, TOS, or OSI when comparing individuals with and without PTSD (all, p>0.05). There were no correlations between Clinician-Administered PTSD Scale scores and oxidant and antioxidant stress markers (all, p>0.05). Our results suggest that the total oxidant and antioxidant status may not affect earthquake survivors with PTSD. This is the first study to evaluate the oxidative status in earthquake survivors with PTSD. Further studies are necessary to confirm these findings.

    Large differences between the concentrations of serum total carbon dioxide (TCO2) and blood gas bicarbonate (HCO3 (-)) were observed in two consecutive simultaneously drawn sets of samples of serum and arterial blood gases in a patient who presented with severe carbon dioxide retention and profound acidemia. These differences could not be explained by the effect of the high partial pressure of carbon dioxide on TCO2, by variations in the dissociation constant of the carbonic acid/bicarbonate system or by faults caused by the algorithms of the blood gas apparatus that calculate HCO3 (-). A recalculation using the Henderson-Hasselbach equation revealed arterial blood gas HCO3 (-) values close to the corresponding serum TCO2 values and clarified the diagnosis of the acid-base disorder, which had been placed in doubt by the large differences between the reported TCO2 and HCO3 (-) values. Human error in the calculation of HCO3 (-) was identified as the source of these differences. Recalculation of blood gas HCO3 (-) should be the first step in identifying the source of large differences between serum TCO2 and blood gas HCO3 (-).

    Deficiency or excess of elements could disrupt proper functioning of the human body and could lead to several disorders. Determination of their concentrations in different biological human fluids and tissues should become a routine practice in medical treatment. Therefore the knowledge about appropriate element concentrations in human organism is required. The purpose of this study was to determine the concentration of several elements (P, S, Cl, K, Ca, Cr, Fe, Cu, Zn, Se, Br, Rb, Pb) in human serum and to define the reference values of element concentration. Samples of serum were obtained from 105 normal presumably healthy volunteers (66 women aged between 15 and 78 years old; 39 men aged between 15 and 77 years old). Analysis has been done for the whole studied population and for subgroups by sex and age. It is probably first so a wide study of elemental composition of serum performed in the case of Świętokrzyskie region. Total reflection X-ray fluorescence (TXRF) method was used to perform the elemental analysis. Spectrometer S2 Picofox (Bruker AXS Microanalysis GmbH) was used to identify and measure elemental composition of serum samples. Finally, 1st and 3rd quartiles were accepted as minimum and maximum values of concentration reference range.

    Oxidative stress is involved in a variety of diseases. Prospective studies investigating the relationship between oxidative stress biomarkers and the status and development of colorectal cancer (CRC) are scarce; previous studies have failed to establish a relationship between the serum total oxidant/antioxidant status and CRC. Therefore, we compared the total serum oxidant/antioxidant levels of CRC patients and healthy subjects, and analyzed their clinical significance in the CRC. Fasting blood samples from 132 CRC patients and 64 healthy subjects were collected. Oxidative stress parameters, including total oxidant status (TOS) and total antioxidant status (TAS), were measured, and the oxidative stress index (OSI) was calculated. The TOS and OSI levels increased significantly (POxidative stress parameters differed significantly depending on the patient's smoking and drinking status (P0.05).However, the levels of TOS, TAS, and OSI were significantly different between patients with no metastasis and those with metastases to two organs (P<0.05) Finally, the parameters are affected by smoking and drinking, and subsequent research should be conducted excluding the relevant influencing factors.

    Emerging work demonstrates that serum bilirubin is a novel biomarker implicated in cardiovascular and metabolic diseases. However, we have a limited understanding of the influence of flavonoid-rich fruit and vegetable consumption on bilirubin levels, which was the purpose of this study. Data from the 2003 to 2006 National Health and Nutrition Examination survey were used (n = 1783; 18-85 years of age), with analyses performed in 2014. Total serum bilirubin was measured from a blood sample. Using a food frequency questionnaire (FFQ), a flavonoid index variable was created summing the frequency of consumption of flavonoid-rich foods. After adjustments, greater consumption of flavonoid-rich fruits and vegetables was positively associated with bilirubin levels. Our findings suggest an association between flavonoid-rich fruit and vegetable consumption and bilirubin levels. If confirmed by prospective and experimental studies, then regular consumption of flavonoid-rich fruits and vegetables should be promoted to increase levels of bilirubin.

    Total human chorionic gonadotropin (hCG) and alpha-fetoprotein (AFP) were measured in maternal serum at 10-14 weeks of gestation from 53 pregnancies affected by trisomy 18, 42 cases with trisomy 13, 46 with Turner's syndrome and 13 with other sex aneuploides. The only significant association was the finding of reduced levels of total hCG in cases of trisomy 18 and 13. The association of increased levels of AFP in cases of trisomy 18 with ventral wall defects and the slight increase in AFP in cases of sex chromosomal anomalies other than Turner's syndrome was found. AFP and total hCG are not likely to replace the markers free beta-hCG and PAPP-A in first trimester screening for chromosomal anomalies. Copyright 2000 John Wiley & Sons, Ltd.

    The results of several studies point to the positive role of vegetarian diets in reducing the risk of diabetes, some cancers and cardiovascular diseases. However, exclusion of animal products in vegetarian diets may affect the cobalamin status and cause an elevation of the plasma homocysteine level. The aim of this study was to assess the effect of vegetarian diets on serum concentrations of homocysteine, folate, vitamin B12 and total antioxidant status (TAS) in children. The study included 32 vegetarians (including 5 vegans), age 2-10 years. Dietary constituents were analyzed using a local nutritional programme. Serum homocysteine, folate and vitamin B12 were determined with fluorescence and chemiluminescence immunoassays. The concentration of TAS was measured by a colorimetric method. Average daily energy intake and the percentage of energy from protein, fat and carbohydrates in the diets of the studied children were just above or similar to the recommended amounts. It could be shown that vegetarian diets contain high concentrations of folate. In vegan diets it even exceeds the recommended dietary allowance. Mean daily intake of vitamin B12 in the studied diets was adequate but in vegans was below the recommended range. The serum concentrations of homocysteine, folate, vitamin B12 and TAS in vegetarian children remained within the physiological range. The presented data indicate that vegetarian children, contrary to adults, have enough vitamin B12 in their diet (excluding vegans) and normal serum concentrations of homocysteine, folate and vitamin B12. Therefore, in order to prevent deficiencies in the future, close monitoring of vegetarian children (especially on a vegan diet) is important to make sure that they receive adequate quantities of nutrients needed for healthy growth.

    Abstract Obesity is related to an increased risk of gastric cardia cancer. However, the influences of excess body weight and serum total cholesterol on the risk of gastric high-grade dysplasia have not been fully characterized. A case–control study was conducted to explore the relationships between body mass index (BMI), serum total cholesterol level, and the risk of gastric high-grade dysplasia in Chinese adults. A total of 893 consecutive patients with gastric high-grade dysplasia (537 men and 356 women) and 902 controls (543 men and 359 women) were enrolled from January 2000 to October 2015. Odds ratios (ORs) with 95% confidence intervals (CIs) were estimated, and a multivariate analysis was conducted. After adjusting for age, alcohol consumption, smoking status, family history of gastric cancer or esophageal cancer, and serum total cholesterol level, a BMI ranging from 27.5 to 29.9 was significantly related to an increased risk of gastric high-grade dysplasia in both men (adjusted OR = 1.87, 95% CI = 1.24–2.81) and women (adjusted OR = 2.72, 95% CI = 1.44–5.16). The 2 highest BMI categories (27.5–29.9 and ≥30.0) were identified as risk factors for gastric cardia high-grade dysplasia in both men (BMI = 27.5–29.9: adjusted OR = 1.78, 95% CI = 1.02–3.10; BMI ≥ 30.0: adjusted OR = 2.54, 95% CI = 1.27–5.08) and women (BMI = 27.5–29.9: adjusted OR = 2.88, 95% CI = 1.27–6.55; BMI ≥ 30.0: adjusted OR = 2.77, 95% CI = 1.36–5.64), whereas only a BMI ranging from 27.5 to 29.9 was a risk factor for gastric noncardia high-grade dysplasia in both men (adjusted OR = 1.98, 95% CI = 1.25–3.14) and women (adjusted OR = 2.88, 95% CI = 1.43–5.81). In addition, higher serum total cholesterol was associated with an increased risk of gastric noncardia high-grade dysplasia (adjusted OR = 1.83, 95% CI = 1.25–2.69) in women. Increased BMI was associated with an increased risk

    The vegetarian diet may play a preventive role in the development of chronic diseases such as coronary heart and cardiovascular disease. However increase of homocysteine (Hcy) concentration in peoples avoiding animal products may contribute to an increased atherosclerotic risk in these subjects. Recent evidence has suggested that role of hyperhomocysteinemia in atherogenesis is associated with process of autooxidation, which can promote the production of hydroxyl radicals, resulting in oxidative modification of low density lipoprotein and endothelium injury. The oxidant-antioxidant imbalance depends not only on the amount of enhanced free oxygen species but also insufficiency of antioxidant defence system. Total antioxidant status (TAS) expresses capacity for scavenging of free radicals minimizes oxidative damage. The aim of this study was to asses concentrations of homocysteine and total antioxidant status in serum of children on vegetarian and omnivorous diet. We also studied levels of vitamin A (retinol) and vitamin E (alpha-tocopherol) particular components of TAS. The study included 35 children, aged 5-16 who had been referred to Institute of Mother and Child for dietary consultation. From those, 17 were lacto-ovo-vegetarians and 18 omnivores. Dietary constituents were analyzed using the nutritional programme Dietetyk2 and completed with supplementation data. Concentration of homocysteine was estimated in serum with fluorescence polarization immunoassay and TAS by colorimetric method. Levels of vitamin A and E were determined using high-pressure liquid chromatography (HPLC). The mean concentration of homocysteine was similar in both studied groups (vegetarians: 6.13 +/- 1.01 micromol/l vs. omnivores: 5.45 +/- 0.98 micromol/l). In vegetarian children serum level of TAS was significantly lower (1.21 +/- 0.06 mmol/I) as compared to those in non-vegetarian ones (1.30 +/- 0.05 mmol/l, p vegetarians were lower than observed in omnivores group, but only in case of

    Full Text Available This study assessed the effect of oral administration of Aloe vera and was to evaluate total serum protein, albumin and globulin concentrations as well as albumin / globulin (A / G ratio. Twenty rabbits weighing 1000 – 1800 g were divided into 2 groups. Each group consisted of ten animals. One served as control and other group served as experimental group. Results show that animals after 07, 15 and 30 days dosing of Aloe vera showed highly significant decrease in total protein and globulin and highly significant decrease in Albumin after 15 and 30 days of dosing of Aloe vera in comparison to control animals group. It is concluded that the long-term use of Aloe vera may cause hypoglobinemia and hypoalbuminemia at 30 days of dosing and it could be due to the liver diseases, evidence of hepatotoxicity induced Aloe vera also reported in previous studies.

    Background/Aims. Glucocorticoids may have adverse effects on carbohydrate and lipid metabolism. The present study was conducted to investigate possible effects on carbohydrate and lipid metabolism of inhaled and oral glucocorticoids in children with asthma. Methods. Two randomised controlled trials with blinded crossover designs were performed. Active treatment was 400  μ g inhaled budesonide or 5 mg prednisolone orally daily during one week. The budesonide trial included 17 and the prednisolone trial 20 school children. Serum fructosamine, total cholesterol and high-density lipoprotein were assessed. Results. Serum fructosamine was increased during active treatment (prednisolone 252.3  μ M versus placebo 247.3  μ M; P = 0.03 and budesonide 228.1  μ M versus no treatment 223.1  μ M; P = 0.02). Total cholesterol and high-density lipoprotein were not statistically significantly increased. Conclusion. Short-term treatment with oral prednisolone and inhaled budesonide may adversely affect mean blood glucose concentration. Possible long-term consequences require further investigations.

    Iron deficiency anemia (IDA) during pregnancy continues to be of world-wide concern. IDA is a risk factor for preterm delivery and subsequent low birth weight, and possibly for poor neonatal health. Iron supplementation in pregnancy is a widely recommended practice, yet intervention programs have met with many controversies. In our study, 300 women at different trimesters of pregnancy were enrolled in a trial of oral administration of ferrous sulfate (520 mg once a day) or 30% iron-saturated bovine lactoferrin (bLf) (100 mg twice a day). Pregnant women refusing treatment represented the control group. In this group hemoglobin and total serum iron values measured after 30 d without treatment decreased significantly, especially in women at 18-31 weeks of pregnancy. In contrast, after 30 d of oral administration of bLf, hemoglobin and total serum iron values increased and to a greater extent than those observed in women treated orally for 30 d with ferrous sulfate, independently of the trimester of pregnancy. Unlike ferrous sulfate, bLf did not result in any side effects. These findings lead us to hypothesize that lactoferrin could influence iron homeostasis directly or through other proteins involved in iron transport out of the intestinal cells into the blood.

    Study on the Refractometric Determination of Total Protein in Serum, Comparison of the Refractometric and Biuret Method. Total protein concentration in serum was determined by the aid of the Abbé-refractometer and the biuret method. Both methods showed a good precision and accuracy. The investigation was carried out in 241 sera with normal bilirubin (up to 1 mg/100 ml), cholesterol (up to 200 mg/100 ml) and urea (up to 23,0 mg/100 ml) concentration, in 43 sera with increased (10,6-26,6 mg/100 ml) bilirubin concentration, in 129 sera with increased (200-520 mg/100 ml) cholesterol concentration and in 43 sera with increased (23,0-155,3 mg/100 ml) urea concentration. The comparison of the refractometric values with the values obtained by the biuret method in the 241 sera with normal bilirubin, cholesterol and urea concentration (correlation coefficient = 0,971) showed a close correlation and in the 43 sera with increased bilirubin concentration (correlation coefficient = 0,958) an acceptable correlation. However no close correlations were observed in the 129 sera with increased cholesterol concentration and in the 43 sera with increased urea concentration. The correlation lines diverged proportional with the increase of cholesterol and urea concentration from the expected correlation lines.

    Background: Several lipid-related hormones and peptides, such as glucagon-like peptide-1 and leptin, are involved in the regulation of taste and smell function. However, to our knowledge, it remains unknown whether these chemosensory functions are associated with lipid profiles.Objective: We examined the cross-sectional association between taste and smell dysfunction and blood cholesterol concentrations.Methods: With the use of a questionnaire, we assessed chronic smell and taste dysfunction in 12,627 Chinese participants (10,418 men and 2209 women; mean age: 54.4 y) who did not take hypolipidemic agents. Participants were categorized into 3 groups based on the number of smell and taste dysfunctions, ranging from 0 (best) to 2 (worst). A general linear model was used to test differences in serum concentrations of total cholesterol, LDL cholesterol, HDL cholesterol, and triglycerides (TGs) across groups with different smell and taste status after adjusting for age, sex, education, occupation, smoking, drinking, obesity, and history of cardiovascular disease, cancer, and head injury.Results: The prevalence of smell and taste dysfunction was 2.4% and 1.2%, respectively. Worse smell and taste dysfunction was associated with higher total cholesterol concentrations (P-trend = 0.005). No significant differences were observed in LDL cholesterol, HDL cholesterol, and TG concentrations across groups with different numbers of chemosensory dysfunctions (P-trend > 0.1 for all). The associations between chemosensory dysfunction and total cholesterol concentrations were more pronounced in participants aged ≤60 y and in those who were nonsmokers relative to their counterparts (P-interaction < 0.05 for all).Conclusions: In this large cross-sectional study, chemosensory dysfunction was associated with higher serum total cholesterol concentrations among Chinese adults. Prospective studies are needed to investigate the temporal relation between these chemosensory dysfunctions and

    Routine tests that measure the concentration of electrolytes in serum are needed for diagnosis and management of renal, endocrine, acid-base, water balance and other conditions such as screening D- and A-vitamin disorders, kidney insufficiency, bone diseases and leukaemia. The diagnostic concentration ranges for many such markers are narrow, requiring reference methods with small uncertainty. Serum concentration of total selenium (Se) is important in health studies but there is increasing interest in the speciation of selenium compounds in clinical samples such as serum and individual Se- Species are bio-indicators of Se status. The last CCQM IAWG key comparison for elements in the clinical area (CCQM-K14: Ca in human serum) was organized in 2003 and the previous key comparison (CCQM-K60) for Se and Se species used a wheat flour sample. Therefore, the CCQM IAWG agreed that CCQM-K107 and a parallel pilot study CCQM-P146 should be carried out. The candidate human serum sample used for both CCQM-K107 and P146 is of high complexity and contains approximately 1000-fold lower concentrations of selenium methionine (SeMet) than those encountered in the CCQM-K60 wheat flour. This significantly broadens the scope and degree of difficulty of earlier measurements in this field. A total of eleven institutes participated in CCQM-K107 (11 participants for total elements and 7 for SeMet). The performance of the majority of the K107 participants for all the measurands was very good, illustrating their ability to obtain accurate results for analytes such as electrolytes at mg kg-1 level, essential elements at µg kg-1 level and selenium species at µg kg-1 level in a complex biological fluid. The range of agreement between participants was within the interval of ± 0.1% for Ca and up to ± 1.8% for Fe. CMC claims based on total elements in this study may include other elements with similar core competencies (e.g. Se, Cu, Zn) in a wide range of biological materials (including liquids

    We describe the preparation of glutaraldehyde cross-linked and functionalized cholesterol esterase nanoparticles (ChENPs) and cholesterol oxidase nanoparticles (ChOxNPs) aggregates and their co-immobilization onto Au electrode for improved amperometric determination of serum total cholesterol. Transmission electron microscope (TEM) images of ChENPs and ChOxNPs showed their spherical shape and average size of 35.40 and 56.97 nm, respectively. Scanning electron microscope (SEM) studies of Au electrode confirmed the co-immobilization of enzyme nanoparticles (ENPs). The biosensor exhibited optimal response at pH 5.5 and 40°C within 5 s when polarized at +0.25 V versus Ag/AgCl. The working/linear range of the biosensor was 10-700 mg/dl for cholesterol. The sensor showed high sensitivity and measured total cholesterol as low as 0.1 mg/dl. The biosensor was evaluated and employed for total cholesterol determination in sera of apparently healthy and diseased persons. The analytical recovery of added cholesterol was 90%, whereas the within-batch and between-batch coefficients of variation (CVs) were less than 2% and less than 3%. There was a good correlation (r = 0.99) between serum cholesterol values as measured by the standard enzymic colorimetric method and the current method. The initial activity of ENPs/working electrode was reduced by 50% during its regular use (200 times) over a period of 60 days when stored dry at 4°C.

    Full Text Available Objective: To report the case of a 28-year old hypercholesterolemic female with postpartum depression, whose triglyceride (TG and total cholesterol (TC levels decreased while being treated with fluoxetine. Method: A 28-year old female, with a diagnosis of major depressive disorder with postpartum onset based on DSM-IV criteria, was hospitalized at a mental health hospital. Her past history included another episode of depression 4 months after giving birth to her second child, which was 12 years prior to her recent episode. Her serum total cholestrol and triglyceride levels were measured prior to the initiation of medication. Then fluoxetine was initiated at a daily dose of 20 mg and had been increased to 40 mg per day at the time of discharge. The lipid profile measurements was repeated at week 4 and 8 following treatment. Results: Total cholesterol level was reduced from 242 mg/dL at baseline to 224 mg/dL at week 4 and to 202 mg/dL at week 8; triglyceride level was decreased from 516 mg/dL to 448 mg/dL at week 4 and to 404 mg/dL at week 8. Conclusions: Fluoxetine may be an appropriate treatment for hyperlipidemic women with postpartum depression..

    Lifestyle-related risk factors such as hyperglycemia and dyslipidemia have been associated with several cancers. However, studies exploring their link with prostate cancer (PCa) clinicopathological characteristics are sparse and inconclusive. Here, we investigated the associations between serum metabolic markers and PCa clinicopathological characteristics. The study comprised 14,294 men from the Swedish Apolipoprotein MOrtality RISk (AMORIS) cohort who were diagnosed with PCa between 1996 and 2011. Univariate and multivariable logistic regression were used to investigate the relation between glucose, triglycerides and total cholesterol and PCa risk categories, PSA, Gleason score, and T-stage. Mean age at time of PCa diagnosis was 69 years. Men with glucose levels >6.9 mmol/L tend to have PSA20 μg/L compared to PSA 4.0-9.9 μg/L. Hypertriglyceridemia was also positively associated with PSA>20 μg/L. Hyperglycemic men had a greater odds of intermediate- and high-grade PCa and advanced stage or metastatic PCa. Similarly, hypertriglyceridemia was positively associated with high-grade PCa. There was also a trend toward an increased odds of intermediate risk localized PCa and advanced stage PCa among men with hypertriglyceridemia. Total cholesterol did not have any statistically significant association with any of the outcomes studied. Our findings suggest that high serum levels of glucose and triglycerides may influence PCa aggressiveness and severity. Further investigation on the role of markers of glucose and lipid metabolism in influencing PCa aggressiveness and severity is needed as this may help define important targets for intervention.

    Diabetes is strongly associated with several mechanisms of tissue damage such as oxidative stress. Serum bilirubin may have a beneficial role in preventing oxidative changes in cardiovascular disease (CVD). Limited information is available on whether serum bilirubin is an independent confounding factor for carotid atherosclerosis among elderly persons with type 2 diabetes. The study subjects were 169 men aged 79 ± 8 (mean ± SD) years and 205 women aged 81 ± 8 years that were enrolled consecutively from patients in the medical department. Carotid intima-media thickness (IMT) and plaque were derived via B-mode ultrasonography. Multiple linear regression analysis showed that serum total bilirubin (β = -0.160) was significantly associated with carotid IMT. Compared to subjects with a serum total bilirubin of tertile-1 (0.13-0.58 mg/dL), the multivariate-adjusted odds ratio (95% confidence interval) of carotid IMT ≥1.0 mm including plaque and carotid plaque was 0.46 (0.23-0.93) and 0.32 (0.17-0.60) in the Tertile-3 group (0.87-1.93 mg/dL), respectively. Next, data were further stratified by gender, age, smoking status, medication and prevalence of CVD. There were no significant differences in serum total bilirubin levels between selected subgroups. Our data demonstrated a negative association between serum total bilirubin and carotid atherosclerosis among elderly persons with type 2 diabetes.

Deficiency of this enzym can lead to hemolysis of red blood cells. Our aim was to study the prevalence of G6PD deficiency in relation to neonatal jaundice. We studied 456 clinically icteric neonates Laboratory investigations included determination of direct and indirect serum bilirubin concentrations, blood group typing, direct coomb's test, hemoglobin, blood smear, reticulocyte count and G6PD level. We divided these neonates to 3 groups based on total serum bilirubin level (TSB: TSB< 20 mg%, TSB=20-25 mg%, and TSB>25 mg%. In only 35 (7.6% of cases G6PD deficiency was diagnosed. All of these babies were male. From 456 icteric neonates, 213 cases belong to group 1 (TSB<20 mg%, 158 cases belong to group 2 (TSB=20-25 mg% and 85 cases belong to group 3 (TSB>25 mg%. 16 neonates from 213 neonates of group 1, 6 neonates from 158 neonates of group 2 and 13 neonates from 85 neonates of group 3 had G6PD deficiency. There was statistically significant difference of prevalence of G6PD deficiency between group 2 and 3 ( 15.3% vs 3.8%( P = 0.001. Between groups 1 vs 2 and 1 vs 3 no statistically significant difference was found. Early detection of this enzymopathy regardless of sex and close surveillance of the affected newborns may be important in reducing the risk of severe hyperbilirubinemia. This emphasizes the necessity of neonatal screening on cord blood samples for G6PD deficiency.

    2012-02-01

    BACKGROUND & AIMS: Hip fractures are a significant cause of mortality and morbidity in the elderly. Malnutrition is a significant contributor to this, however no consensus exists as to the detection or management of this condition. We hypothesise that results of admission serum albumin and total lymphocyte count (TLC), as markers of Protein Energy Malnutrition (PEM) can help predict clinical outcome in hip fracture patients aged over 60 years. METHODS: This retrospective study evaluated the nutritional status of patients with hip fractures using albumin and TLC assays and analysed their prognostic relevance. Clinical outcome parameters studied were delay to operation, duration of in-patient stay, re-admission and in-patient, 3- and 12-month mortality. RESULTS: Four hundred and fifteen hip fracture patients were evaluated. Survival data were available for 377 patients at 12 months. In-hospital mortality for PEM patients was 9.8%, compared with 0% for patients without. Patients with PEM had a higher 12-month mortality compared to patients who had normal values of both laboratory parameters (Odds Ratio 4.6; 95% CI: 1.0-21.3). Serum albumin (Hazard Ratio 0.932, 95% CI: 0.9-1.0) and age (Hazard Ratio 1.04, 95% CI: 1.0-1.1) were found to be significant independent prognostic factors of mortality by Cox regression analysis. CONCLUSIONS: These results highlight the relevance of assessing the nutritional status of patients with hip fractures at the time of admission and emphasises the correlation between PEM and outcome in these patients.

    Full Text Available OBJECTIVES: Variations in sex hormones and the calcium balance can influence bone health in men. The present study aimed to examine the relationship between the calcaneal speed of sound and biochemical determinants of bone mass, such as sex hormones, parathyroid hormones and serum calcium. METHODS: Data from 549 subjects from the Malaysian Aging Male Study, which included Malay and Chinese men aged 20 years and older residing in the Klang Valley, were used for analysis. The subjects' calcaneal speed of sound was measured, and their blood was collected for biochemical analysis. Two sets of multiple regression models were generated for the total/bioavailable testosterone and estradiol to avoid multicollinearity. RESULTS: The multiple regression results revealed that bioavailable testosterone and serum total calcium were significant predictors of the calcaneal speed of sound in the adjusted model. After adjustment for ethnicity and body mass index, only bioavailable testosterone remained significant; the total serum calcium was marginally insignificant. In a separate model, the total testosterone and sex hormone-binding globulin were significant predictors, whereas the total serum calcium was marginally insignificant. After adjustment for ethnicity and body mass index (BMI, the significance persisted for total testosterone and SHBG. After further adjustment for age, none of the serum biochemical determinants was a significant predictor of the calcaneal speed of sound. CONCLUSION: There is a significant age-dependent relationship between the calcaneal speed of sound and total testosterone, bioavailable testosterone and sex hormone-binding globulin in Chinese and Malay men in Malaysia. The relationship between total serum calcium and calcaneal speed of sound is ethnicity-dependent.

    A highly sensitive and simple fluorimetric method for the determination of free and total polyamines, spermidine, spermine, putrescine and cadaverine, in human serum by high-performance liquid chromatography is described. The polyamines, obtained after clean-up of deproteinized serum by Cellex P column chromatography, are converted to their fluorescamine derivatives in the presence of nickel ion which inhibits the reaction of interfering amines with fluorescamine, and the derivatives are separated simultaneously by reversed-phase chromatography (LiChrosorb RP-18) with a linear gradient elution. The lower limits of detection are 10 and 15 pmole for spermine and the others in 0.5 ml of serum, respectively.

    We describe a peroxidase-coupled method involving a colorimetric indicator reaction for determining the total activity of creatine kinase (EC 2.7.3.2) in serum. The kinetically favorable reverse reaction is exploited to generate adenosine 5'-triphosphate, which is used in the glycerol kinase-catalyzed phosphorylation of glycerol. The glycerol 3-phosphate so generated is oxidized in the presence of alpha-glycerophosphate oxidase to produce hydrogen peroxide, which is reduced in the presence of peroxidase with the simultaneous oxidation and coupling of 4-aminoantipyrene and 2-hydroxy-3,5-dichlorobenzenesulfonate to produce an intensely colored red chromogen. Results of the proposed method (y) correlate well with those of the Boehringer-Mannheim "CK-NAC UV" method as applied to the Hitachi 705 chemistry analyzer (y = 1.025 chi - 18.1, r = 0.9985, n = 100, range = 19-4531 U/L). The sensitivity of the method, based on molar absorptivities, is nearly fourfold that of procedures involving the reduction of NADP+.

    Familial aggregation of allergy has been demonstrated in numerous past studies. However, allergy is a complex disorder which is not inherited as a simple Mendelian trait. Total serum IgE levels correlate with the clinical expression of allergy and asthma and can be utilized as a quantitative measure of the allergic phenotype. We studied 92 families from Northern Holland ascertained through a parent with asthma who were originally studied between 1962-1970. Since there is a large number of candidate genes on chromosome 5q, families were genotyped for markers in this region. These genes either directly or indirectly regulate IgE production and the activation and proliferation of cellular elements that are involved in inflammation associated with allergy and asthma. They include IL-4, IL-3, IL-5, IL-9, IL-12, IL-13 and GM-CSF. Segregation analyses revealed recessive inheritance of `high` levels with a mean for the `low` phenotype of 1.51 (32 IU) and 2.52 (331 IU) for the `high` phenotype. Linkage of log IgE with markers on 5q was tested using the sib-pair and the LOD score methods with the genetic model obtained from the segregation analyses. These results provide evidence for a locus controlling IgE levels near the cytokine gene cluster on 5q. This region appears critical in susceptibility to allergy and asthma.

    Full Text Available Abstract Background The Lp(a lipoprotein (Lp(a consists of the polymorphic glycoprotein apolipoprotein(a (apo(a, which is attached by a disulfide bond to apolipoprotein B (apoB. Apo(a, which has high homology with plasminogen, is present only in primates and hedgehogs. However, transgenic mice and rabbits with high serum apo(a levels exist. Liver is the main site for apo(a synthesis, but the site of removal is uncertain. To examine differences between transgenic mice expressing the LPA gene and mice capable of forming Lp(a particles, LPA-YAC transgenic mice and hAPOB transgenic mice were crossed and their offspring examined. Results Comparison of LPA-YAC with LPA-YAC/hAPOB transgenic mice showed that LPA-YAC/hAPOB transgenic mice have higher serum total apo(a and total cholesterol level than mice lacking the hAPOB gene. However, hepatic apo(a mRNA level was higher in LPA-YAC transgenic mice than in LPA-YAC/hAPOB transgenic mice. Feeding of a high-cholesterol/high-fat diet to male LPA-YAC transgenic mice with or without the hAPOB gene resulted in reduced serum total apo(a and hepatic apo(a mRNA level. Conclusion In conclusion, the higher serum total apo(a level in LPA-YAC/hAPOB transgenic mice than in LPA-YAC transgenic mice is not caused by increased apo(a synthesis. Lower hepatic apo(a mRNA level in LPA-YAC/hAPOB than in LPA-YAC transgenic mice may suggest that the increase in total apo(a level is a result of apo(a accumulation in serum. Furthermore, observed higher serum total cholesterol level in LPA-YAC/hAPOB transgenic mice than either in wild type or LPA-YAC transgenic mice may further suggest that human APOB transgenicity is a factor that contributes to increased serum total apo(a and cholesterol levels. Our results on reduced serum total apo(a and hepatic apo(a mRNA levels in HCHF fed male LPA-YAC transgenic mice confirm earlier findings in females, and show that there are no sex difference in mechanisms for lowering apo(a level in

    Two enzyme immunoassays for the quantitative determination of total thyroxine (T4) and total triiodothyronine (T3) in human serum were validated to measure total T4 and T3 in rat serum. The specificity, sensitivity, detectability and reproducibility have been tested as well as the effects of different anaesthetics (pentobarbital and a mixture of ketamine and xylacine) on serum thyroid hormone levels. Hormones were quantified, by means of a previously validated technique, 18 hours after surgery for the placement of a stem for blood extraction in conscious and freely moving animals. Thyroid serum levels, especially T3, were slightly lower in xylacine plus ketamine treated animals than in those treated with pentobarbital. The administration of glutamic acid, stimulated the secretion of thyroid hormones, this effect appearing 30 minutes after its administration and it was independent of the anaesthetic used during the surgery for the cannula placement, although in pentobarbital treated rats, the serum T3 level increase induced by glutamate appears 60 minutes after the treatment.

    We describe a fluorescent determination of total cholesterol in serum for which the accuracy and precision are comparable to that for the method of Abell-Kendall, a method of generally accepted accuracy. By the use of quality reagents and the rigorous exclusion of water, the strong fluorophor that develops on reacting concentrated sulfuric acid with cholesterol can be used to quantitatively determine the total cholesterol in serum. We used gas-liquid chromatography to monitor the extent of saponification of the cholesterol esters, because we found them to have fluorescent efficiencies that differed from that of free cholesterol. Sodium methoxide in methanol/methylene chloride (1/3 by vol) was shown by gas-liquid chromatography to very effectively saponify the cholesterol esters in serum.

    Elevated serum total cholesterol is a major and modifiable risk factor for heart disease, the lead-ing cause of death in the United States (1,2). Reducing mean total serum cholesterol levels among adults to less than 200 mg/dL and reducing the proportion who have levels of 240 mg/dL or higher to less than 17% are national Healthy People 2010 objectives (3). Age-adjusted mean serum cholesterol levels among adults aged 20-74 years declined from 222 mg/dL in 1960-1962 to 203 mg/dL in 1999-2002 (4). Among adults aged 20 years and older, the percent of the population with high serum total cholesterol levels (240 mg/dL or higher) declined from 20% during 1988-1994 to 17% during 1999-2002 (4). In individual patients, a high serum total cholesterol level indicates a potential increased risk for heart disease, but further evaluation of other risk factors and the specific components of cholesterol provide the basis for determining the need for initiating therapeutic lifestyle changes or treatment with medication (5). Low-density-lipoprotein (LDL) is the cholesterol component associated with arterial blockage, and it is the primary clinical target for cholesterol management. High-density-lipoprotein (HDL) may help to protect individuals from developing heart disease. In populations, comparisons of total cholesterol levels over time can show if population groups are experiencing improvement in cholesterol levels, and knowledge of trends in levels of total cholesterol can help identify subgroups where additional prevention efforts may be needed.

    A series of trials were conducted to evaluate Brix refractometry (Brix %) for the assessment of failure of passive transfer (FPT) in dairy calves compared to: (1) serum IgG (reference standard) when measured by radial immunodiffusion (RID) or a turbidometric immunoassay (TIA), and (2) serum total protein refractometry (STP). For the serum samples tested with TIA, STP, and Brix % (n = 310; Holstein calves), the median concentrations were 21.3 g/L IgG, 58 g/L STP, and 9.2%, respectively. For the serum samples tested with RID, STP and Brix % (n = 112; Jersey calves), the mean concentrations were 38 g/L IgG, 68 g/L STP, and 10.2%, respectively. For samples tested with only Brix % and STP (n = 265; Holstein calves), median STP and Brix % were 50 g/L STP and 8.5%, respectively. Correlations between Brix % and RID, and between Brix % and TIA were equal (r = 0.79, respectively). Brix % and STP were positively correlated (r = 0.99). Brix % estimated serum IgG concentrations determined by TIA and RID (r(2) = 0.63, 0.62, respectively). When FPT was defined as serum IgG Brix % ≤ 8.5% showed optimal sensitivity (100%) and specificity (89.2%) to predict FPT. At the same IgG cut-point, an STP value of ≤ 52 g/L showed a similar sensitivity (100%) and specificity (80.4%) to predict FPT. Brix refractometry predicted successful transfer of passive immunity in dairy calves, but further evaluation as a diagnostic tool for the diagnosis of FPT is warranted.

    Full Text Available Aim and Objective: The objective of this study is to estimate and compare the serum and salivary immunoglobulin G and A (IgG, IgA levels in various stages of oral submucous fibrosis (OSMF patients and relate it to total serum protein (TSP and hemoglobin (Hb levels. Materials and Methods: The sample for the present study comprised a total of 20 healthy controls, 20 OSMF patients. About 5 ml of blood and 2 ml of saliva were collected. Quantitative analysis of serum and salivary IgG, IgA was done by turbidometric immunoassay. TSP and Hb were estimated by Biuret and cyanmethemoglobin methods, respectively. Results: Serum and salivary IgA and IgG levels were statistically significantly increased (P < 0.001 in OSMF patients when compared to controls. Also serum and salivary IgG and IgA levels showed significantly increased (P < 0.01 in all the three staging of OSMF when compared to control group. Hb levels and TSP levels were significantly decreased (P < 0.001 in OSMF patients when compared to controls. One-way ANOVA, Pearson's correlation, and unpaired t -test were used for statistical analysis. Conclusion: The elevated levels of IgG and IgA are also in favor of polygammapathy, which are nonspecific and nondiagnostic objective reflections of an underlying disease. Decreased TSP is a result of host response and Hb, acts as an indicator of nutritional status plays an important role. It is also observed from the present study that the severity of OSMF was directly proportional to the estimated elevated levels of the major IgG and IgA. A need is also felt for the knowledge of immunoprofile estimation in etiology and pathogenesis that would prove a great asset in the proper assessment of this condition.

    There are substantial variations of relative risks (RR) in smoking-related mortality by country and time. We hypothesized the RRs in smoking-related mortality might differ depending on serum concentrations of persistent organic pollutants (POPs). We evaluated the associations of cigarette smoking with total mortality in 610 elderly (aged ≥ 70 yr) (702 elderly for organochlorine pesticides [OCPs]) after stratification by serum concentration of POPs, in the National Health and Nutrition Examination Survey (NHANES) 1999-2004 followed through 2006. Summary measures of POPs subclasses showed significant or marginally significant interaction with cigarette smoking on the risk of total mortality. P values for interaction were 0.069 for polychlorinated dibenzo-p-dioxins (PCDDs), 0.008 for polychlorinated biphenyls (PCBs), and 0.024 for OCPs. The effect of smoking on total mortality showed different patterns according to the serum concentration of some POPs. Former or current smokers had 1.4 to 2.9 times higher mortality rates compared with never smokers among participants with higher serum concentrations of POPs (2nd or 3rd tertiles). However, when the level of PCBs or OCPs were low (1st tertile), there were little positive associations between smoking and mortality. Our study suggests that the background exposure to several POPs may be related to variability in smoking-related total mortality. PMID:23960436

    We examined the role of hepatic interleukin (IL)-1alpha/beta in serum total cholesterol homeostasis using male and female IL-1-knockout (KO) mice and wild-type (WT) mice. Serum total cholesterol level was higher in males than in females in WT and KO mice. The difference between sexes was closely correlated with the difference in gene expression level of cholesterol 7alpha-hydroxylase (Cyp7a1), a rate-limiting enzyme for bile acid synthesis. No significant sex difference in gene expression level of 3-hydroxy-3-methylglutaryl-CoA reductase, a rate-limiting enzyme for cholesterol synthesis, was observed in WT mice. Interestingly, the gene expression level of hepatic Cyp7a1 was lower in KO mice than in sex-matched WT mice, while the serum total cholesterol level was the opposite. The present findings demonstrate that IL-1alpha and IL-1beta are positive regulators for the Cyp7a1 gene in steady-state mice and that Cyp7a1 is one of the factors that mediate the difference in serum total cholesterol level between sexes.

    Full Text Available Abstract. The serum levels of cytokines and total IgE in 113 children with salmonellosis were tested in ELISA. It was established, that severe course of infection in chidren up to 4 years of age is associated with low level of IL-10, and after 4 years of age with IFNγ deficit. Low level of total IgE is the marker of severe salmonellosis too, particularly in children up to 4 years of age.

    Serum testosterone is mostly bound to the sex hormone-binding globulin and albumin. A small metabolically active part is present in the form of free testosterone (FT). The relationship between serum total testosterone (TT) levels and prostate carcinogenesis is debated. Our hypothesis is that the serum FT concentration is more closely associated with the risk of prostate cancer (PC) and its aggressiveness than TT. To analyze the scientific evidence that relates serum TT and/or FT levels with the diagnosis of PC and its aggressiveness. A systematic review was conducted in PubMed up to January 2015 using the following mesh terms: prostate cancer, sex hormone, androgen, testosterone and free testosterone. We found 460 publications, 124 of which were reviewed to analyze the evidence. The relationship between serum TT levels and the diagnosis of PC and its aggressiveness is highly heterogeneous. The variability in the design of the studies, the quantification methods and other variables could explain this heterogeneity. In a number of studies that evaluated the estimated or measured FT, the evidence remains equally conflicting. Based on the current evidence, we cannot recommend the measurement of serum TT and/or TL levels for the diagnosis of PC or for assessing its aggressiveness. Copyright © 2015 AEU.

    Human placenta expresses CD320, a receptor that ensures the uptake of holo-transcobalamin (holoTC). Soluble CD320 (sCD320) is present in the circulation and its concentration increases during pregnancy. To investigate a possible association of sCD320, holoTC and total transcobalamin (TC) with the risk of subsequent preeclampsia using serum samples from asymptomatic first trimester pregnant women. Moreover, we aimed to establish reference intervals of the aforementioned biomarkers for first trimester pregnant women who remained healthy throughout pregnancy. This study was a retrospective case-control study that we performed on biobank serum samples. Cases (n = 50) and controls (n = 198) (matched for gestational age and date of sample collection) were asymptomatic women in early pregnancy [median (range) gestational age = 10 (8-12) weeks]. Cases developed preeclampsia while the controls remained normotensive throughout pregnancy. We measured the serum concentration of sCD320, holoTC, and total TC by using in-house ELISA methods. First trimester median concentrations of sCD320, holoTC and total TC were not significantly different between cases and controls. The odd ratio for developing preeclampsia based on exposure to low or high levels of sCD320, holoTC or total TC at first trimester was not significant. The reference intervals (2.5-97.5% percentiles (median)) derived from the controls were 50-170 (90) pmol\\L for sCD320, 20-140 (70) pmol\\L for holoTC and 560-1300 (810) pmol\\L for total TC. The risk of preeclampsia is not predicted by first trimester serum concentrations of sCD320, holoTC or total TC. The first trimester reference intervals for the three parameters is reported.

    Liver function tests (LFTs) have been reported as independent predictors of non-liver disease-related morbidity and mortality in general population and cancer patients. In this study, we evaluated the relationship between pretreatment serum LFTs and overall survival (OS) in non-metastatic Caucasian breast cancer patients. Seven LFTs, including albumin, alanine aminotransferase, aspartate aminotransferase, alkaline phosphatase, lactate dehydrogenase (LDH), total bilirubin and total protein, were measured in pretreatment serum from 2425 female Caucasian patients with newly diagnosed, histologically confirmed non-metastatic invasive breast cancer. Multivariate Cox model was used to estimate hazard ratio (HR) and 95% confidence interval (CI) for the association of individual LFTs with 5-year OS while adjusting for age, smoking status, pathological characteristics and treatment regimen. We found that serum albumin, LDH and total bilirubin were significantly associated with 5-year OS in multivariate Cox analyses. Patients with higher albumin level exhibited 45% reduced risk of death (HR = 0.55, 95% CI: 0.40-0.75) compared with those with lower albumin level. Patients with higher total bilirubin level had a nearly 40% reduction in the risk of death (HR = 0.62, 95% CI: 0.45-0.85) and patients with higher LDH levels had a 1.42-fold increased risk of death (HR = 1.42, 95% CI: 1.08-1.88). Furthermore, cumulative analysis showed a significant dose-response trend of significantly increasing risk of death with increasing number of unfavorable LFT levels. Our result highlighted the potential of using pretreatment serum levels of albumin, LDH and total bilirubin as prognostic factors for OS in patients with non-metastatic breast cancer.

    To determine the comparability of triceps and subscapular skinfold thicknesses with dual X-ray absorptiometry (DXA) whole-body total fat (kg) in relation to serum triglyceride (TG) levels and increased risk of elevated TG levels, and identified optimum skinfold cutoffs for screening purposes in US adolescents. Data from triceps and subscapular skinfold thickness, DXA whole-body total fat and serum TGs were obtained from 1505 US adolescents ages 12.00-17.99 years, who participated in two continuous National Health and Nutrition Examination Survey (NHANES) cycles 2001-2004. Study associations were examined with linear and logistic models, and ROC (receiver operating characteristic) analyses were used to derive skinfold cutoffs for identifying the risk of elevated TG levels. Using area under the curves (AUCs) as metrics of prediction accuracy (with bootstrapped 95% CIs), no significant differences were found between skinfolds and DXA logistic models for predicting elevated TG levels. Similarly, skinfold and DXA models had comparable precision in predicting continuous serum TG from bootstrapped root mean squared errors for both sexes. Population-adjusted marginal mean estimates indicated that youths whose skinfolds are in the top quartile had TG levels within 83-108 mg/dl. Skinfold cutoffs for predicting elevated estimated TG using ROC analyses showed that cutoffs decreased with age and ranged from 13 to 30 mm for ages 12-17, in yearly intervals. Skinfold thicknesses were comparable to DXA whole-body total fat in predicting serum TG levels. These skinfold cutoffs could be used in practical settings as a first pass screener for identifying US adolescents at risk of elevated serum TGs.

    Body condition in wild ungulates is traditionally evaluated during the necropsy of animals on the basis of the weight of fat stored around or within the vital organs, the weight of the organs themselves, and their derived indices. However, sometimes it is important to evaluate the nutritional status of the animal by means of blood and serum analyses and the interpretation of specific parameters. Only in a very few studies is the nutritional status of the animal obtained by blood biochemistry and, when obtained, compared with the values for body condition obtained by anatomic dissection. In this study, the usefulness of two serum parameters, total serum proteins (TSP) and serum triglycerides (ST), was assessed in the monitoring of the body condition of Iberian wild goats (Capra pyrenaica). In addition, their relationship with the kidney fat index (KFI) and its components, kidney mass without fat (KM) and kidney fat (KF) is evaluated. A total of 25 wild goats from the Sierra Nevada National Park (southern Iberian Peninsula) that were shot by hunters were used in this study. The parameter TSP was found to be correlated with KM, and ST was correlated with both KM and KFI. Hence, both TSP and ST can be used for monitoring physical condition in wild and captive Iberian wild goats.

  19. The predictive value of total serum IgE for a positive allergen specific IgE result

    OpenAIRE

    2004-01-01

    Background: Measurement of total serum IgE and allergen specific IgE is often requested to assess possible allergy. As public awareness increases, so do requests for allergy assessment; unless there is a clear “allergen suspect” in the history, several allergen specific IgE requests may be made. This increases the likelihood of detecting borderline increases in allergen specific IgE of uncertain relevance, and has important cost implications for the service.

    Organochlorine pesticides, due to their hydrophobic nature and persistence, accumulate in tissues rich in lipids, which had been used as a biomarker for environmental pollution. In humans, organochlorine pesticides are continuously circulating and equilibrating among body compartments. The objective of the study was to evaluate the concentrations of organochlorine pesticides in blood serum and compare their levels to the total lipid contents in Veracruz, México inhabitants. Our hypothesis is that concentrations of organochlorine pesticides will increase just as lipid concentrations. Levels of organochlorine pesticides were divided in ascending tertils according to their total lipid content. The linear trend model applied surprisingly reveals that the average level of all organochlorine pesticides decreases as the lipid concentration increases. From one tertil to the next β-HCH, it shows a decrease of -3.19 mg kg(-1) on lipid basis, pp.'DDE levels decrease by -3.70 mg kg(-1) on lipid basis and pp.'DDT levels decrease -1.13 mg kg(-1) on lipid basis. We conclude that the levels and the orderly sequence of organochlorine pesticide distributions in the blood serum maintain an inverse relationship to total lipid blood serum concentrations.

    Full Text Available Abstract Background The association between dietary total antioxidant capacity (TAC from different assays and serum C-reactive protein (CRP has not been assessed in non-Western populations. We examined the association between dietary TAC and serum CRP concentration in young Japanese women using different four TAC assays. Methods The subjects were 443 young Japanese women aged 18–22 years. Dietary TAC was assessed with a self-administered diet history questionnaire and the TAC value of each food using the following four assays: ferric reducing ability of plasma (FRAP; oxygen radical absorbance capacity (ORAC; Trolox equivalent antioxidant capacity (TEAC; and total radical-trapping antioxidant parameter (TRAP. Serum CRP concentrations were measured by highly sensitive nephelometry. Results The major contributor to dietary TAC was green, barley, and oolong tea (FRAP: 53%, ORAC: 45%, TEAC: 36%, and TRAP: 44%. The prevalence of elevated CRP concentrations (≥ 1 mg/L was 5.6%. TAC from FRAP was inversely associated with serum CRP concentrations (adjusted odds ratio [OR] for elevated CRP concentration in high [compared with low] dietary TAC group: 0.39 [95% confidence interval (CI: 0.16-0.98]; P = 0.04. TAC from ORAC was inversely associated with CRP, although the association was not significant (OR: 0.48 [95% CI: 0.20-1.14]; P = 0.10. TAC from TEAC was inversely associated with CRP (OR: 0.32 [95% CI: 0.12-0.82]; P = 0.02, as was TAC from TRAP (OR: 0.31 [95% CI: 0.12-0.81]; P = 0.02. Conclusions Dietary TAC was inversely associated with serum CRP concentration in young Japanese women regardless of assay. Further studies are needed in other populations to confirm these results.

    Vitamin D is a fat-soluble micronutrient that regulates inflammation and skeletal muscle size and function. Inflammation and skeletal muscle dysfunction (i.e., atrophy and weakness) are predominant impairments that continue to challenge the rehabilitation from total knee arthroplasty (TKA). Data suggest a decrease in serum 25-hydroxyvitamin D (25(OH)D) concentrations after TKA. Despite the decrease being attributed to a systemic inflammatory response, it is unclear what inflammatory mediator(s) is contributing to the decrease in serum 25(OH)D concentrations after TKA. In immune cells, pro-inflammatory cytokines mediate the enzymatic conversion of 25(OH)D to 1,25-dihydroxyvitamin D, implying that pro-inflammatory cytokines contribute to the decrease in substrate availability (i.e., 25(OH)D). We propose the hypothesis that pro-inflammatory cytokines mediate the decrease in serum 25(OH)D concentrations after TKA. To complement the supporting literature for the proposed hypothesis, we analyzed serum 25(OH)D and pro-inflammatory cytokine concentrations prior to and serially after TKA in a case subject (female; age, 62 year; height, 160 cm; body mass, 63 kg; body mass index, 26.5 kg/m(2)). The subtle decrease (12%) from pre-surgery to 2-d post-surgery and the more pronounced decrease (74%) from 3-week to 8-week post-surgery in serum 25(OH)D concentrations corresponded with the increase in serum pro-inflammatory cytokine (i.e., TNF-α, IFN-γ, IL-1β, GM-CSF, and IL-6) concentrations. This observation lends credence to the proposed hypothesis that pro-inflammatory cytokines could contribute to the decrease in serum 25(OH)D concentrations after TKA. Clearly, future research is needed to confirm the proposed hypothesis and to identify if attenuating the decrease in serum 25(OH)D concentrations improves patient outcomes after TKA.

    Four procedures for assessment of adequacy of colostral immunoglobulin (Ig) transfer in foals were evaluated. Results of zinc sulfate turbidity test, serum electrophoresis, total serum protein refractometry, and sodium sulfite precipitation test were compared with immunoglobulin G content determined by single radial immunodiffusion. The zinc sulfate turbidity test gave acceptable results for IgG, except that hemolyzed serum samples gave higher than expected values. A correction factor for hemolyzed serum was found to be useful. Serum electrophoresis was a satisfactory method of estimating IgG content. Total serum protein values may not be a valid basis for estimating IgG content, inasmuch as postsuckling total protein values were found to decrease in some foals in which passive transfer of IgG had been adequate. Sodium sulfite precipitation reactions were too unpredictable to be of value for determination of neonatal IgG concentration.

    Leptin secreted from adipose tissue signals peripheral energy status to the brain. Monogenic leptin deficiency results in severe early onset obesity with hyperphagia. Recently, a similar phenotype of inactivating leptin mutations but with preserved immunoreactivity and hence normal circulating immunoreactive leptin has been reported. We aimed to evaluate the proportion of bioactive leptin serum levels (compared to immunoreactive leptin) as a biomarker for the screening of leptin gene mutations causing monogenic obesity. Furthermore, we aimed to compare the immunoreactive and bioactive leptin levels associations with parameters of insulin resistance and insulin secretion in obese children and adolescents. We measured bioactive and immunoreactive leptin levels by enzyme-linked immunosorbent assays in fasting serum samples of 70 children with severe (BMI SDS >3) non-syndromic obesity with onset leptin gene was performed in probands with proportion of bioactive/immunoreactive leptin leptin were almost identical (41.1±25.2 vs. 41.1±25.4ng/mL). In three probands with the lowest bioactive leptin proportion (leptin gene. Compared to immunoreactive leptin, bioactive leptin showed similar and slightly better statistical associations with indices of insulin resistance in correlation and multivariate analyses. In our sample selected for severe early onset childhood obesity, we did not identify leptin gene mutations leading to decreased proportion of bioactive leptin. Nevertheless, the bioactive leptin levels were stronger associated with selected insulin secretion/resistance indices than the immunoreactive leptin levels.

    Nobuto filter paper strips are widely used for storing blood-serum samples, but the recovery of proteins from these strips following rehydration is unknown. Poor recovery of proteins could reduce the concentration of antibodies and antigens and reduce the sensitivity of diagnostic assays. We compared the protein concentration, and its association with test sensitivity, of eluted Nobuto strip samples with paired sera. We collected and froze serum from five gray wolves (Canis lupus) for 8 mo. When thawed, we used a spectrophotometer (absorbance 280 nm) to determine the serum protein concentration for paired sera and Nobuto eluates for each animal in 2-fold serial dilutions. Total protein concentration was similar for both sample storage methods (Nobuto eluates and control sera), except for the undiluted samples in which Nobuto eluates had higher total protein concentrations. Both sample storage methods appear to produce similar results using the SNAP® 4Dx® Test to detect antibodies against pathogens causing Lyme disease, anaplasmosis, and ehrlichiosis as well as antigen for canine heartworm disease.

    Bilirubin is known to have a physiologic role as an antioxidant that efficiently scavenges peroxyl radicals and suppresses oxidation, and oxidative stress has detrimental effects on bone metabolism. In the present study, we performed a 3-year longitudinal study of healthy middle-aged men, investigating the association between serum total bilirubin concentrations and annualized changes in bone mineral density (BMD). The study enrolled a total of 917 Korean men aged 40 years or older who had undergone comprehensive routine health examinations with an average follow-up interval of 3 years. BMD at proximal femur sites was measured with dual-energy X-ray absorptiometry using the same equipment at baseline and follow-up. The overall mean annualized rates of bone loss at the total femur, femoral neck, and trochanter were -0.25 %/year, -0.34 %/year, and -0.44 %/year, respectively. After adjustment for potential confounders, the rates of bone loss at all proximal femur sites were significantly attenuated in a dose-response fashion across increasing bilirubin concentrations (P = 0.006-0.046). Moreover, compared to subjects in the lowest bilirubin quartile category, those in the highest bilirubin quartile category showed significantly less bone loss at all proximal femur sites after adjustment for confounding factors (P = 0.010-0.048). This study provides the first clinical evidence that serum total bilirubin could be a protective marker against future bone loss, especially in subjects without liver diseases.

    Immunoglobulin E (IgE) is a central mediator of allergic (atopic) inflammation. Therapies directed against IgE benefit hay fever1 and allergic asthma1,2. Genetic association studies have not yet identified novel therapeutic targets or pathways underlying IgE regulation3-6. We therefore surveyed epigenetic association between serum IgE concentrations and methylation at loci concentrated in CpG islands (CGI) genome-wide in 95 nuclear pedigrees, using DNA from peripheral blood leukocytes (PBL). We validated positive results in additional families and in subjects from the general population. We show here replicated associations with a meta-analysis false discovery rate <10−4 between IgE and low methylation at 36 loci. Genes annotated to these loci encode known eosinophil products, and also implicate phospholipid inflammatory mediators, specific transcription factors, and mitochondrial proteins. We confirmed that methylation at these loci differed significantly in isolated eosinophils from subjects with and without high IgE levels. The top three loci accounted for 13% of IgE variation in the primary subject panel, explaining 10 fold higher variance than that derived from large SNP GWAS3,4. The study identifies novel therapeutic targets and biomarkers for patient stratification for allergic diseases. PMID:25707804

    The effects of total lymphoid irradiation (TLI) on serum levels of autoantibodies, and of antibodies to diphtheria toxoid, tetanus toxoid, and pneumococcal polysaccharide in patients with lupus nephritis were compared with those previously observed in rheumatoid arthritis (RA) patients. Baseline levels of antibodies to diphtheria toxoid and tetanus toxoid decreased significantly after TLI in patients with lupus and RA, but antibody levels to pneumococcal polysaccharide remained unchanged. After TLI, the levels of antinuclear and anti-DNA antibodies were reduced significantly in lupus, but levels of rheumatoid factor, antinuclear, and antigranulocyte antibodies all tended to increase in RA.

    The short- and long-term effects of a single exposure to gamma radiation on steroid metabolism were investigated in mice. Gas chromatography-mass spectrometry was used to generate quantitative profiles of serum steroid levels in mice that had undergone total-body irradiation (TBI) at doses of 0Gy, 1Gy, and 4Gy. Following TBI, serum samples were collected at the pre-dose time point and 1, 3, 6, and 9 months after TBI. Serum levels of progestins, progesterone, 5β-DHP, 5α-DHP, and 20α-DHP showed a significant down-regulation following short-term exposure to 4Gy, with the exception of 20α-DHP, which was significantly decreased at each of the time points measured. The corticosteroids 5α-THDOC and 5α-DHB were significantly elevated at each of the time points measured after exposure to either 1 or 4Gy. Among the sterols, 24S-OH-cholestoerol showed a dose-related elevation after irradiation that reached significance in the high dose group at the 6- and 9-month time points.

    Sodium arsenite is an environmental pollutant with the ability to generate free radicals and curcumin acts as a potent antioxidant. This study investigates the effect of curcumin on kidney histopathology, lipid peroxidation and antioxidant capacity of serum in the mice treated with sodium arsenite. Adult male mice were divided into four groups: control, sodium arsenite, curcumin and curcumin+sodium arsenite. The treatments were delivered for 5 weeks. After the treatment period, blood samples were collected and the concentrations of malondialdehyde (MDA) and total antioxidant capacity of serum were determined. Left kidney was dissected, weighed and used for histopathological and histomorphometrical studies. Sodium arsenite-treated mice showed a significant decrease in the diameter of glomerulus and proximal tubule, glomerular area, total antioxidant capacity of serum as well as a significant increase in serum concentration of MDA compared to the control group. However, no significant difference was found in kidney weight, area and diameter of Bowman's capsule as well as the diameter of distal tubule in mice treated with sodium arsenite compared to the control. In curcumin+sodium arsenite group, curcumin significantly reversed the adverse effects of sodium arsenite on the diameter of glomerulus and proximal tubule, glomerular area, total antioxidant capacity of serum and serum concentration of MDA compared to the sodium arsenite group. The application of curcumin alone significantly increased the total antioxidant capacity of serum compared to the control. Curcumin compensated the adverse effects of sodium arsenite on kidney tissue, lipid peroxidation and total antioxidant capacity of serum.

    Full Text Available The aim of this study was to investigate the distribution of ultratrace elements in rat tissues and to perform a comparative analysis of hair and serum as potential bioindicators of the total ultratrace element content. Thirty-six male Wistar rats were fed a standard chow containing 0.006±0.000, 0.001±0.000, 0.017±0.002, 0.382±0.031, 0.168±0.014, 3.211±0.134, 0.095±0.006, 0.000±0.000, 6.675±0.336, 15.327±0.564, 0.002±0.000, and 1.185±0.202 μg/g of silver (Ag, gold (Au, cesium (Cs, gallium (Ga, germanium (Ge, lanthanum (La, niobium (Nb, platinum (Pt, rubidium (Rb, titanium (Ti, thallium (Tland zirconium (Zr, respectively, from weaning to 3 months old. The ultratrace element content in the liver, kidney, muscle, heart, serum and hair was assessed using inductively coupled plasma mass spectrometry. The obtained data indicate that the highest concentrations of most of the studied elements (Ti, Zr, Ge, Nb, tungsten (W, La, uranium (U, Ag, Au, Pt are in hair, whereas the lowest were observed in the serum. Statistical analysis revealed a significant association between concentrations in the hair and other tissues for Cs, Ti, Nb, Tl, La, U and Au. At the same time, serum Cs, Rb, Ti, Ge, Nb, W, Ga, Tl and La concentrations significantly correlated with the tissue content of the respective ultratrace elements. It can be concluded that hair may be used as a potential bioindicator for certain ultratrace element content in the mammalian organism.

    Several studies have suggested that bilirubin, a potent innate antioxidant, plays a protective role against cardiovascular and microvascular disease. This study investigated the association between serum concentrations of total bilirubin (TB) and the presence of diabetic peripheral neuropathy (DPN) in Korean diabetic patients. This cross-sectional study involved 1207 patients aged more than 30 years with type 2 diabetes. DPN was assessed according to clinical symptoms and physical examinations using Michigan Neuropathy Screening Instrument examination score, 10-g monofilament sensation, and current perception threshold. The subjects were stratified into gender-specific tertiles based on TB values, and the relationship between the TB values and DPN was analyzed. Compared with patients within the lowest TB tertile, those with higher TB levels consisted of patients with shorter duration of diabetes, lower HbA1c, better renal function, and less autonomic neuropathy, retinopathy, and albuminuria. Serum TB levels were inversely associated with DPN. In multivariate analysis for the development of DPN after adjusting for potential confounding factors including retinopathy, albuminuria, and autonomic neuropathy, the TB levels were inversely associated with the presence of DPN, both as a continuous variable [odds ratio (OR) per log standard deviation (SD) 0.79; 95% confidence interval (CI) 0.65-0.97; P = 0.022] and when categorized in tertiles (the highest vs. the lowest tertile; OR 0.63; 95% CI 0.40-0.99; P = 0.046). Low serum bilirubin levels are significantly associated with DPN, independently of classic risk factors and other microvascular complications. Further investigation is necessary to determine whether serum bilirubin has a prognostic significance on DPN.

    Full Text Available Introduction: Obesity and high fat diet (HFD has side effcts on male fertility. Th aim of this study was to evaluate the effct of apple vinegar on spermatogenesis and serum total antioxidant status (TAS in rats under HFD. Methods: Twenty-four Wistar male rats were divided to three groups, including (n = 8: control, HFD, HFD + apple vinegar. Th control group received 16.6 kcal/day and the other two groups received HFD containing 51.6 kcal/day. Aftr 16 weeks, group 3 received %5 apple vinegar in drinking water orally for six weeks. At the end of the experiment, epididymis sperm parameters including: count, morphology and motility, were measured. Serum level of TAS, testosterone and estradiol was assayed with enzyme linked immunosorbent assay (ELISA. Testicular apoptosis was assayed with terminal deoxynucleotidyl transferase (TdT dUTP nick-end labeling (TUNEL and spermatogenesis was studied with quantitative histologic method. Statistical analysis was performed using analysis of variance (ANOVA and Tukey’s test. Results: Apple vinegar increased count and forward motility of sperms, when compared with HFD (P < 0.05. However, it was not effctive on morphology. Numbers of apoptotic cells reduced in the vinegar-treated group (P < 0.001. Vinegar increased serum levels of testosterone and TAS compared with HFD (P < 0.05. However, estradiol level was not changed. Vinegar reduced the lee index, when compared with HFD (P < 0.001. Th numbers of spermatogonia, primary pachytene and leptotene spermatocyte, and round spermatids were not changed. However, the numbers of elongated spermatids were increased compared with HFD (P < 0.05. Conclusions: Ths study indicated that daily use of apple vinegar in rats under HFD for six weeks improved spermatogenesis through reduction of testis apoptosis, increasing serum TAS and testosterone.

    Bronchodilator responsiveness has been associated with a subsequent accelerated decline in forced expiratory volume in one second (FEV1). Therefore, bronchodilator responsiveness and total serum immunoglobulin E(IgE) levels were assessed in 184 adult first-degree relatives of probands with severe early-onset chronic obstructive pulmonary disease (COPD) and a control group. Greater bronchodilator responsiveness was found among current smokers or exsmokers who were first-degree relatives of early-onset COPD probands than in currently or exsmoking controls, expressed as increase in FEV1 as a percentage of baseline (5.8+/-8.1 versus 2.9+/-5.1%, p<0.01), absolute increase in FEV1 from baseline (120+/-130 versus 60+/-110 mL, p<0.05), and increase in FEV1 as a percentage of the predicted value (3.6:4.1 versus 2.2+/-3.9%, p<0.05). However, elevated total serum IgE levels were not found in first-degree relatives of early-onset COPD probands compared with control subjects. The increased bronchodilator responsiveness among currently smoking/exsmoking first-degree relatives of early-onset COPD probands suggests that these individuals may have enhanced susceptibility to the detrimental effects of cigarette smoking.

    Background Screening for IgA deficiency in patients with coeliac disease is essential because of the increased incidence of IgA deficiency associated with the disease, which usually relies on the estimation of IgA levels in each case. Aim To devise a method of excluding IgA deficiency without measuring total serum IgA in each case. Materials and methods The optical density readings on enzyme‐linked immunosorbent assay (ELISA) of 608 routine samples received for tissue transglutaminase (TTG) antibody testing for coeliac disease were compared with their total IgA concentrations. Dilution experiments were also carried out to ensure linear relationships between optical density on ELISA and IgA concentrations and to compare the sensitivities for TTG and endomysium antibodies in TTG‐positive samples. Results and discussion A clear relationship was shown between total IgA concentration and TTG optical density readings by ELISA. To ensure a positive TTG result if antibodies are present, it was possible to recommend an optical density level above which all samples have sufficient IgA. Samples with optical density <0.05 should be investigated further by estimating total IgA and, if low, samples should be subjected to immunofluorescence microscopy testing for IgA and IgG endomysium antibodies. Conclusions An easier, more cost‐effective and practical way of excluding IgA deficiency in the investigation on coeliac disease is reported. PMID:16489174

  1. The Relationship Between Serum Levels of Total IgE, IL-18, IL-12, IFN- γ and Disease Severity in Children With Atopic Dermatitis

    Full Text Available Studies about the role of cytokines on the immunopathogenesis of atopic dermatitis (AD are generally based on in vitro observations and this role has not been completely clarified yet. Serum levels of total IgE, IL-18, IL-12, IFN- γ and the relationship between these parameters and disease severity, determined using the SCORAD index, in a group of atopic patients were investigated in this study. Serum levels of total IgE were measured by the nephelometric method and serum levels of IL-18, IL-12/p40 and IFN- γ were measured by ELISA method. Serum levels of total IgE and IL-18 were found significantly higher in study group than in controls ( p<.001 . There was no statistically significant difference between patients and controls in respect of serum levels of IL-12/p40 ( p=.227 . A statistically significant relationship between SCORAD values and serum levels of total IgE ( p<.001 , IL-18 ( p<.001 , and IL-12/p40 ( p<.001 was determined. These results show that serum levels of IL-18 can be a sensitive parameter that importantly correlates with clinical severity of AD, can play a role in the immunopathogenesis of AD, and furthermore may be used in the diagnosis and follow-up of the disease in addition to other parameters.

    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.

    Many racing jurisdictions monitor pre-race serum concentration of total carbon dioxide (TCO2) among racing horses. To our knowledge, factors influencing concentration of TCO2 among horses participating in racing have not been systematically evaluated and reported. To determine if characteristics of horses and racing conditions routinely recorded were significantly associated with pre-race concentration of TCO2, while accounting for and estimating effects of trainer and horse. Pre-race serum TCO2 concentrations from 5028 starts made by 2,349 horses trained by 287 trainers at 2 racetracks in California during 2005 were examined. Data regarding characteristics of starters and race conditions obtained from a commercial database were recorded for each start. Data were analysed using mixed-effects, with TCO2 concentration as the dependent variable, and trainer and horse nested within trainer as random effects. Sex, class and distance of race, frusemide administration and cloudy weather conditions were significantly (Prace TCO2 concentration. Horses that finished in the top 3 positions had values that were slightly (0.2 mmol/) but significantly (Phorses not finishing in the top 3. There were significant effects of trainer on pre-race TCO2 concentration. A variety of factors may influence pre-race TCO2 concentration in horses. Horses with better performance tend to have higher pre-race TCO2 concentrations. TCO2 concentration is associated with improved performance although the magnitude of effect was quite small. Regulatory programmes based on monitoring should consider the influence of other factors on TCO2 concentration.

    Determination of the health status of reptiles is based on physical examination and evaluation of hematologic and biochemical values. Evaluation of serum total protein (TP) concentration and protein fractions plays an important role in health assessment; however, little is known about references value for these analytes in wild viperoid snakes. In addition, studies evaluating the stability of proteins in frozen viperoid serum are lacking. The aims of this study were to establish preliminary reference values for concentrations of TP and protein fractions in serum from wild vipers and to evaluate the stability of serum proteins in frozen serum samples from viperoid snakes. Blood samples were collected from wild Horned Vipers (Vipera ammodytes ammodytes). Using fresh serum, TP concentrations were determined using the biuret method and protein fractions were analyzed using agarose gel electrophoresis (AGE); albumin/globulin ratios were calculated. Analyses were also performed on serum frozen at -20°C for 70 days and then thawed. Pre- and post-storage results were compared using the Mann-Whitney U-test. Five adult wild Horned Vipers were sampled and comprised 4 males and 1 female. The female snake had higher TP concentrations than the male snakes. The electrophoretic patterns demonstrated 6 protein fractions that were similar for all 5 snakes. There were no significant changes in the concentrations of the 6 protein fractions post-storage; the percentage of the alpha-1 fraction was increased in frozen/thawed serum. Total protein concentrations in serum from Vipera ammodytes ammodytes were in agreement with published reference intervals for healthy reptiles and viperoid snakes. Serum protein fractions were easy to identify using AGE electrophoresis. © 2012 American Society for Veterinary Clinical Pathology.

    The role of vasopressin (AVP) in the pathophysiology of cardiovascular disease is controversial, but this peptide hormone is elevated in heart failure and some forms of hypertension. Also, AVP has vasoconstrictor, mitogenic, hyperplasic and renal fluid retaining properties which, by analogy with angiotensin II, may have deleterious effects when present in chronic excess. Furthermore, cholesterol blood levels are also associated with hypertension, although the underlying mechanism is not known. Here we analyze the relationship between blood total cholesterol levels and serum vasopressin- degrading cystyl-aminopeptidase activity (AVP-DA) in healthy humans, and the differences between men and women. Linear correlation coefficients were calculated to test relationships between AVP-DA and blood total cholesterol levels. Sex differences were observed for AVP-DA, being this activity higher in men than in women. According to the linear model of the regression analysis, AVP-DA showed a significant negative correlation with blood total cholesterol levels in men, whereas no correlation was observed in women. Several studies in humans demonstrate the existence of greater plasma AVP concentrations in normal men compared to normal women, which could explain the gender-differences observed in the present work in relation with AVP-DA. However, AVP-DA is related to blood cholesterol levels only in men, although in our hands, women showed higher blood cholesterol levels than men. This could indicate that the risk of high cholesterol-related hypertension is more probable in men than in women. Although AVP-DA misregulation could be involved in the pathogenesis of hypertension, its relation with cholesterol levels appears only in men, but not in women.

    Full Text Available Background/Aims: Calcium sensing receptor (CaSR is expressed, among others also in testis. Cinacalcet binds to the CaSR, increases sensitivity of CaSR to serum calcium and is used in the treatment of secondary hyperparathyroidism (sHPT in chronic hemodialysis patients (HDP. In most of male HDP, serum testosterone concentration is lower than in healthy males. The aim of this study was to assess the influence of six-month treatment with cinacalcet on the serum total and free testosterone concentration in male HDP with sHPT. Methods: 38 male, hemodialysed CKD patients with sHPT (PTH>300 pg/ml were enrolled into the study. In each patient serum PTH, total testosterone (TT and free testosterone (FT concentrations were assessed before the first dose of cinacalcet and then after 3 and 6 months of treatment. The results are presented as means with 95% confidence interval. Results: In 33 patients who completed the study cinacalcet treatment caused significant decrease of serum PTH from 1143 pg/ml (828 - 1458 pg/ml at the baseline, to 809 pg/ml (487 - 1132pg/ml after 3 month of treatment (p = 0.002, and to 607 pg/ml (281 - 934pg/ml; p Conclusion: Treatment with cinacalcet decreases serum total and free testosterone concentration in male hemodialysed patients with chronic kidney disease and secondary hyperparathyroidism.

    To determine the relationship between serum total 25-hydroxyvitamin D (25(OH)D), directly measured free 25(OH)D and calculated free 25(OH)D with regard to vitamin D-binding protein (DBP) phenotypes, sex, BMI, age and season, and their interrelationship to vitamin D supplementation. A randomized controlled trial with 20 000 IU of vitamin D3 per week or placebo for 12 months was designed. A total of 472 subjects, 236 in each of the intervention groups, were included in the analyses. Baseline serum concentrations and increases in serum total 25(OH)D, directly measured free 25(OH)D, calculated free 25(OH)D and DBP. Serum total 25(OH)D and DBP concentrations were significantly lower in subjects with the phenotype Gc2/Gc2 compared to phenotypes with the Gc1S allele, and lower in males compared to females. When using directly measured free 25(OH)D, the differences related to DBP phenotypes and sexes were clearly diminished. All calculated free 25(OH)D concentrations were overestimated compared to the directly measured free 25(OH)D. Serum parathyroid hormone showed an inverse correlation with all vitamin D parameters analyzed. The increases after 12 months of vitamin D supplementation were not significantly different for any of the vitamin D parameters regardless of DBP phenotype, sex or age. Supplementation with vitamin D did not affect serum DBP. Direct measurements of free 25(OH)D reduce the differences seen in total 25(OH)D between DBP phenotype groups and sexes, probably caused by differences in DBP concentrations. With conditions affecting serum DBP concentrations, direct measurements of free 25(OH)D should be considered. © 2016 The authors.

    Iodine deficiency can impair the reproductive performance of livestock and affect perinatal mortality of offspring, yet diagnosis of deficiency is complicated and guidelines for I supplementation are imprecise. We challenged pasture-grazing pregnant ewes with a long-acting I supplement and a goitrogenic forage, then monitored their I status during gestation and lactation and in their lambs from birth to weaning. Approximately 46 d into gestation, 376 ewes were assigned to 6 groups comprising 3 supplementation levels × 2 diet regimens. On d 0 the groups received an intramuscular injection of iodized oil providing 0, 300, or 400 mg of I. They grazed until d 23, then half of each supplementation group were fed brassica kale until d 85, then all groups returned to pasture for lambing (parturition approximately d 99) and remained there until weaning (d 192). Serum total I concentration (STIC) was measured repeatedly in 8 'monitor' ewes per group and in their lambs and in milk sampled postpartum. Severity of goiter was determined as the thyroid-weight:birth-weight (TW:BW) ratio in 82 newborn dead lambs. Mean ± SE STIC for all ewes was initially 42 ± 2 (range 24 to 105) µg/L. Diet did not affect I concentrations in ewe serum or milk. Responses to iodized oil were proportional to dose level; STIC increased to approximately 150 and 240 µg/L for the 300- and 400-mg I groups and remained greater than 0-mg I groups for 161 d (P kale feeding (1.27 vs. 0.51 g/kg) and lesser with I supplementation (0.35 vs. 1.44 g/kg). Results support the use of STIC as a biochemical criterion. It was sensitive to the effects of I supplementation with responses in ewes and lambs proportional to dose level and it reflected the relationship between ewe and lamb I metabolism. However STIC did not discriminate between groups of ewes fed pasture vs. goitrogenic forage during pregnancy.

    In this case-control study, we aimed to evaluate the serum and seminal plasma levels of Selenium (Se), total antioxidant capacity (TAC), and Coenzyme Q10 (CoQ-10) and determine their relationship with sperm concentration, motility, and morphology in men with idiopathic infertility. A total of 59 subjects were enrolled in the study. Forty four patients were diagnosed with idiopathic male infertility and had abnormal sperm parameters, and 15 subjects had normal sperm parameters with proven fertility. Serum Se, semen Se, and semen TAC levels were significantly different in the fertile and infertile groups (pspermatozoa concentration, motility, and morphology. Additionally, seminal plasma levels of TAC correlated positively with all these sperm parameters. On the other hand, seminal plasma levels of CoQ-10 correlated only with sperm morphology but not with concentration or motility. No relationship was observed between serum levels of TAC or serum levels of CoQ-10 and sperm parameters. In conclusion, serum and seminal plasma Se deficiency may be a prominent determinant of abnormal sperm parameters and idiopathic male infertility. Measurement of serum Se levels may help determine nutritional status and antioxidant capacity in infertile patients, which may help distinguish those patients who will benefit from supplementation therapy.

    Schisandrin B, an active ingredient isolated from the fruit of Schisandra chinensis, increased serum and hepatic triglyceride levels in mice. In the present study, the effective kinetics of schisandrin B on serum/hepatic triglyceride and total cholesterol levels in mice without and with the influence of fenofibrate were investigated. Parameters on hepatic index (the ratio of liver weight to body weight × 100) were also analyzed. Mice were intragastrically treated with schisandrin B at a single dose of 0.2, 0.4, 0.8, or 1.6 g/kg, without or with fenofibrate pretreatment (0.1 g/kg/day for 4 days, p.o.). Twenty-four hours after schisandrin B treatment, serum/hepatic triglyceride and total cholesterol levels were measured. Schisandrin B treatment dose-dependently increased serum and hepatic triglyceride levels as well as hepatic index in mice. In contrast, hepatic total cholesterol levels were decreased in a dose-dependent manner in schisandrin B-treated mice. Data obtained from effective kinetics analysis indicated that the action of schisandrin B on serum triglyceride had a higher specificity than those on hepatic total cholesterol and hepatic index. While fenofibrate pretreatment inhibited the schisandrin B-induced elevation in serum triglyceride levels, it completely abrogated the elevation of hepatic triglyceride levels in schisandrin B-treated mice. The combined treatment with schisandrin B and fenofibrate decreased hepatic total cholesterol level and increased the hepatic index in an additive or semi-additive manner, respectively. In conclusion, the results of effective kinetics analysis indicated that the schisandrin B-induced hypertriglyceridemia was competitively inhibited by fenofibrate. Schisandrin B may offer the prospect of setting up a mouse model of hypertriglyceridemia and fatty liver for screening triglyceride-lowering drug candidates.

    To determine and compare sensitivity, specificity, accuracy, and predictive values of measurement of serum total protein concentration by refractometry as well as 5 commercially available kits for the diagnosis of failure of passive transfer (FPT) of immunity in foals. Prospective study. 65 foals with various medical problems and 35 clinically normal foals. IgG concentration in serum was assessed by use of zinc sulfate turbidity (assay C), glutaraldehyde coagulation (assay D), 2 semiquantitative immunoassays (assays F and G), and a quantitative immunoassay (assay H). Serum total protein concentration was assessed by refractometry. Radial immunodiffusion (assays A and B) was used as the reference method. For detection of IgG or = 6.0 g/dL indicated adequate IgG concentrations. Most assays were adequate as initial screening tests. However, their use as a definitive test would result in unnecessary treatment of foals with adequate IgG concentrations.

    Context An increase in enzyme lactate dehydrogenase (LDH) in serum is a negative prognostic factor for survival in cats affected by lymphoma. Measuring LDH at the time of diagnosis has been studied for differentiating neoplastic disease from non-neoplastic disease in dogs. Inflammatory bowel disease (IBD) and alimentary lymphoma are common diseases in cats. Objective The aim of this study was to determine whether elevation of total LDH occurred in cats with alimentary lymphoma and non-neoplastic gastrointestinal disease, such as IBD, and to evaluate whether this enzyme is useful in supporting the differential diagnosis of these specific diseases. Materials and Methods A prospective non-randomized controlled study was carried-out in a real world setting of three Italian private veterinary clinics. Seventy-one client-owned cats with a history of chronic gastrointestinal symptoms were enrolled; 33 cats were histologically diagnosed as having alimentary lymphoma and 38 cats as having IBD. Serum samples of total LDH analysis were measured. Results Gender (P = 0.016) and age (P = 0.046) were found to be significant factors influencing the differentiation of serum total LDH between cats with alimentary lymphoma and those with IBD. Despite low diagnostic accuracy in the overall population (63%), a cut-off value of serum total LDH ranging from 0.85- to 1.04-times the upper reference limit showed good capability (accuracy >80%) of differentiating these two conditions in neutered males and cats younger than 8 years of age (AUC: 0.805, 0.833; sensitivities: 76.9%, 83.3%; specificities: 80.0%, 76.5%; PPV: 76.9%, 55.6%; NPV: 80.0%, 92.9%; respectively). Conclusions Although our study showed that gender and age are significant factors in differentiating serum total LDH between cats with alimentary lymphoma and those with IBD, this test had poor diagnostic accuracy in differentiating between these two conditions in the overall population.

    OBJECTIVE The objective of this study was to evaluate the effect of phenobarbital and phototherapy combination on the total serum bilirubin of the newborn infants with isoimmune hemolytic disease (IHD) and its impact on blood exchange transfusion rates. PATIENTS AND METHOD This single-blinded, prospective, randomized, controlled trial was conducted between March 2013 and December 2014 at the pediatric ward of two Military Hospitals in Jordan. A total of 200 full-term neonates with IHD were divided randomly into two groups: (1) the phenobarbital plus phototherapy group (n = 103), and (2) the phototherapy-only group (n = 97). Infants in group 1 received an oral dose of 2.5 mg/kg phenobarbital every 12 hours for 3 days in addition to phototherapy. The total serum bilirubin was observed. RESULTS Of the total 200 included newborn infants, 186 infants completed the study: 97 infants were included in group 1 and 89 infants in group 2. The difference between the mean total serum bilirubin levels at 24, 48, and 72 hours after starting the trial was clinically and statistically significant at P < 0.05. The differences between the two groups were also statistically significant at P < 0.05. Of the total 186 who completed the study, only 22 underwent blood exchange transfusion [7 from group 1, and 15 from group 2 (P = 0.0478)]. CONCLUSION In a limited-resources setting, phenobarbital in combination with phototherapy may be helpful to newborn infants with IHD, as it results in a faster decline in total serum bilirubin, thus decreasing the need for blood exchange transfusion than phototherapy alone.

    Serum and mucus lysozyme were measured in male and female Caspian kutum (Rutilus frisii kutum) under seasonal temperature, gonadal growth and reproductive migration. Significant difference with almost similar trend in serum and mucus lysozyme of the female Caspian kutum in sampling time and ovarian growth was observed. However, while there was no significant difference in serum lysozyme of the male specimen in sampling time and testicular growth, significant variations was observed in mucus lysozyme. In addition, there was significant difference in mucus total protein both for male and female specimens. The effectiveness ratio of factors on lysozyme variations followed in descending order by seasonal temperature (main factor), reproductive activity and migration with negligible effect and the lysozyme level was not significantly different in male and female Caspian kutum.

    After the parenteral administration of iron-dextran (imferon), the increased total iron concentrations in serum can be determined by atomic absorption spectroscopy and by colorimetric methods involving sodium dithionite, which reductively dissociates iron from the dextran complex. We report that constant-potential coulometry detects only about 55-70% of dextran-bound iron before dithionite reduction and variable amounts after reaction with the reducing agent. In addition, we have developed a procedure for determining transferrin-bound iron, total iron-binding capacity (TIBC), total iron, and dextran-bound iron with the Kodak Ektachem colorimetric system. In determining total serum iron, the sample is first mixed with sodium dithionite, which rapidly dissociates all dextran-bound iron, but does not remove iron from either transferrin or hemoglobin. After the mixture is applied to an Ektachem slide, transferrin-bound iron is released at pH 4 and is detected together with the iron previously bound to dextran. TIBC is determined by mixing serum with ferric citrate in moderate excess and filtering through a small alumina (Al2O3) column, which binds excess free iron and iron-dextran; the iron in the column eluate represents the TIBC. Transferrin-bound iron is determined by applying diluted serum without added ferric citrate to an alumina column and measuring the iron in the column eluate. Dextran-bound iron is equivalent to the difference between total and transferrin-bound iron. Using this method, we found that transferrin iron-binding sites are saturated in vitro by excess iron-dextran less efficiently than by ferric citrate.

    An increased serum total homocysteine (tHcy) concentration is typically associated with genetic defects involved in Hcy metabolism or related nutritional deficiencies. In this study, the combined effects of methylenetetrahydrofolate reductase (MTHFR) C677T polymorphism and folate and vitamin B12 deficiency on serum total Hcy (tHcy) levels were evaluated in a healthy Chinese population in Yunnan Province, China. The MTHFR C677T polymorphism was genotyped in 330 volunteers (164 men and 166 women) using polymerase chain reaction-restriction fragment length polymorphism analysis. Folate, vitamin B12, and tHcy concentrations were determined by corpuscle immune chemiluminescence assays. The tHcy concentration was determined using an enzymatic assay. Significant negative correlations (pvitamin B12 (r=-0.243). Men had significantly higher serum tHcy concentrations than women (pvitamin group, the serum tHcy level was significantly correlated with the levels of folate (r=-0.334, p=0.001) and vitamin B12 (r=-0.212, p=0.046). The MTHFR C677T polymorphism, folate deficiency, and B12 deficiency were significantly associated with elevated serum tHcy levels. Among these three factors, folate deficiency had the greatest contribution to the serum tHcy concentration, followed by (in order of decreasing effect) MTHFR C677T and vitamin B12 deficiency. Thus, folic acid and vitamin B12 supplementation could help prevent diseases associated with tHcy accumulation, especially in individuals with the MTHFR 677TT genotype. Copyright © 2017.

    Serum selenium concentrations and the activity of plasma glutathione peroxidase (GPx) decrease with the progression of chronic kidney disease (CKD) in human patients. Selenium is considered a limiting factor for plasma GPx synthesis. Plasma total antioxidant capacity (TAC) is decreased in CKD cats in comparison to healthy cats. Serum selenium concentrations and plasma and erythrocyte GPx activity in cats with CKD are lower than in healthy cats. Serum selenium concentrations, the activity of enzymes, and plasma TAC progressively decrease with the progression of kidney disease according to IRIS (International Renal Interest Society) classification. Twenty-six client-owned cats in IRIS stages I-IV of CKD were compared with 19 client-owned healthy cats. A CBC, serum biochemical profile, urinalysis, plasma and erythrocyte GPx activity, serum selenium concentration, and plasma TAC were measured in each cat. Cats in IRIS stage IV CKD had a significantly higher (P = .025) activity of plasma GPx (23.44 ± 6.28 U/mL) than cats in the control group (17.51 ± 3.75 U/mL). There were no significant differences in erythrocyte GPx, serum selenium concentration, and plasma TAC, either among IRIS stages I-IV CKD cats or between CKD cats and healthy cats. Erythrocyte GPx activity, serum selenium concentration, and plasma TAC do not change in CKD cats compared with healthy cats. Selenium is not a limiting factor in feline CKD. Increased plasma GPx activity in cats with stage IV CKD suggests induction of antioxidant defense mechanisms. Antioxidant defense systems might not be exhausted in CKD in cats.

    To date, there is no objective or reliable means of assessing the severity of degenerative joint disease (DJD) and need for joint replacement surgery. Hence, it is difficult to know when an individual with DJD has reached a point where total arthroplasty is indicated. The purpose of the present study is to determine whether serum levels of Alpha-2 HS-glycoprotein (AHSG) as well as bone morphogenetic proteins (BMP-2, 4, 7) can be used to predict the presence of severe DJD of the hip and/or temporomandibular joint (TMJ) (specifically: joints that require replacement). A total of 30 patients scheduled for arthroplasty (diseased) (15 HIP, 15 TMJ) and 120 age-matched controls (healthy/non-diseased) were included. Blood samples were collected from all patients ≥8 weeks after the last arthroplasty. Concentrations of serum analytes were measured using enzyme-linked immunosorbent assays, and these were compared between the Diseased and Healthy groups, utilizing the Mann-Whitney U-test. Patients with disease had significantly higher levels of BMP-2 and BMP-4 and lower levels of AHSG in serum compared to non-diseased humans (p < 0.01). Higher levels of BMP-2, 4 and reduced levels of AHSG appear to characterize patients who have DJD that is severe enough to require total joint replacement. Perhaps measurements of these proteins can be used to make objective decisions regarding the need for total arthroplasty as opposed to the current subjective approaches.

    Triglycerides are widely tested in clinical laboratories using enzymatic methods for lipid profiling. As enzymatic methods can be affected by interferences from biological samples, this together with the non-specific nature of triglycerides measurement makes it necessary to verify the accuracy of the test results with a reference measurement procedure. Several such measurement procedures had been published. These procedures generally involved lengthy and laborious sample preparation steps. In this paper, an improved reference measurement procedure for triglycerides and total glycerides was reported which simplifies the sample preparation steps and greatly shortens the time taken. The procedure was based on isotope dilution gas chromatography-mass spectrometry (IDGC-MS)with tripalmitin as the calibration standard. Serum samples were first spiked with isotope-labeled tripalmitin. For the measurement of triglycerides, the serum samples were subjected to lipid extraction followed by separation of triglycerides from diglycerides and monoglycerides. Triglycerides were then hydrolyzed to glycerol, derivatized and injected into the GC–MS for quantification. For the measurement of total glycerides, the serum samples were hydrolyzed directly and derivatized before injection into the GC-MS for quantification. All measurement results showed good precision with CV triglycerides and total glycerides were well within the certified ranges of the CRM, with deviation triglycerides and total glycerides.

  5. Genome-wide association study for levels of total serum IgE identifies HLA-C in a Japanese population.

    Full Text Available Most of the previously reported loci for total immunoglobulin E (IgE levels are related to Th2 cell-dependent pathways. We undertook a genome-wide association study (GWAS to identify genetic loci responsible for IgE regulation. A total of 479,940 single nucleotide polymorphisms (SNPs were tested for association with total serum IgE levels in 1180 Japanese adults. Fine-mapping with SNP imputation demonstrated 6 candidate regions: the PYHIN1/IFI16, MHC classes I and II, LEMD2, GRAMD1B, and chr13∶60576338 regions. Replication of these candidate loci in each region was assessed in 2 independent Japanese cohorts (n = 1110 and 1364, respectively. SNP rs3130941 in the HLA-C region was consistently associated with total IgE levels in 3 independent populations, and the meta-analysis yielded genome-wide significance (P = 1.07×10(-10. Using our GWAS results, we also assessed the reproducibility of previously reported gene associations with total IgE levels. Nine of 32 candidate genes identified by a literature search were associated with total IgE levels after correction for multiple testing. Our findings demonstrate that SNPs in the HLA-C region are strongly associated with total serum IgE levels in the Japanese population and that some of the previously reported genetic associations are replicated across ethnic groups.

    A method for serum or plasma cholesterol assay involving amperometric measurement of the rate of oxygen depletion in the cholesterol oxidase-catalyzed oxidation of cholesterol is described. The hydrolysis of the serum cholesterol esters is accomplished by saponification of 50 mul of sample with 0.2 ml of ethanolic KOH (1.0 mol/1) containing 0.5% Triton X-100 for 5 min at 75 degrees C. The rate of oxygen consumption in a 25-mul aliquot of this is measured with a Clark electrode in a Beckman Glucose Analyzer and the assay takes about one minute after incubation; results are read digitally on the instrument. The analyzer cell contains 1 ml of 1 M phosphate buffer, pH 7.4, with 100 mg sodium cholate/100 ml and 0.1-0.2 U cholesterol oxidase.

    Full Text Available Caffeine (120 mg/kg was administered intragastrically to pregnant rats daily on gestational days 8-21. An increase in serum concentration of glucose and total protein was found in animals, which were given caffeine. The protein content proved to be highly significant in the experimental group of animals. The control group showed a negative interdependence between body weight gain and glucose concentration. No correlation was found between body weight gain and total protein concentration, yet the glucose concentration significantly influenced the total protein concentration in this group of animals. Among animals which received caffeine, correlations between total protein and glucose concentrations were observed. The analysis did not show that the glucose or total protein concentration significantly influenced the body weight gain of pregnant female rats in the experimental group. The research conducted suggests the possibility of modulating effects of caffeine on adaptive processes during pregnancy.

There are conflicting results for the association of the CD14 C-159T SNP with total serum immunoglobulin E (IgE levels and atopy. There are limited data regarding the association of the CD14 C-159T SNP in subjects of African ancestry. The aim of the study was to determine whether the C-159T SNP and other CD14 SNPs (C1188G, C1341T were associated with total serum IgE levels and with allergy skin test results in nonatopic and atopic subjects; as well as in Caucasian and African American subjects.Methods: A total of 291 participants, 18–40 years old, were screened to determine whether they were atopic and/or asthmatic. Analyses were performed to determine the association between CD14 C-159T, C1188G, or C1341T genotypes with serum IgE levels and with the number of positive skin tests among Caucasian or African American subjects.Results: We found no significant association of serum total IgE level with CD14 C-159T, C1188G, or C1341T genotypes within nonatopic or atopic subjects. Subjects with CD14-159 T alleles had significantly more positive allergen skin tests than subjects without CD14-159 T alleles (P = 0.0388. There was a significant association between the CD14 1188 G allele, but not the CD14 1341 T allele, with the number of positive skin-test results in Caucasians, but not in African Americans.Conclusion: These results support a possible association between CD14 polymorphisms and atopy. CD14-159 T or CD14 1188 G alleles were associated with atopic

    To assess serum iron and ferritin concentrations, total iron-binding capacity, and transferrin saturation as indicators of iron metabolic status in 3 genera of lemurs and determine whether these variables are useful for screening for iron overload. Cross-sectional study. 11 ring-tailed lemurs (Lemur catta), 11 black lemurs (Eulemur macaco macaco), and 11 red-ruffed lemurs (Varecia rubra). Blood samples were collected weekly for 3 weeks and assayed for serum iron and ferritin concentrations and total iron-binding capacity. Liver biopsy specimens were evaluated histologically and assayed for total iron, nonheme iron, and trace mineral concentrations. Deposition of iron was scored on Prussian blue-stained slides. Hepatic iron content ranged from 497 to 12,800 Pg/g dry weight (median, 2,165 Pg/g). Differences were seen in mean hepatic iron content across genera, with ruffed lemurs having the highest concentrations and ring-tailed lemurs having the lowest. Iron accumulation in the liver was mild, and cellular pathologic changes associated with iron storage disease were not detected in any lemur. Ferritin concentration was the only variable that correlated significantly with hepatic iron content in all 3 genera of lemurs; however, both transferrin saturation and serum iron concentration were correlated with hepatic iron concentration in ring-tailed and ruffed lemurs. Serum ferritin concentration was the only variable that was consistently correlated with hepatic iron content in all 3 genera. Mean hepatic iron content varied across genera, suggesting that the propensity for lemurs to develop iron overload in captivity may vary across taxa.

    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.

    Full Text Available Mast cell leukemia (MCL is a very rare form of systemic mastocytosis (SM with a short median survival of 6 months. We describe a case of a 65-year-old woman with aleukaemic variant of MCL with a very high serum total tryptase level of 2255 μg/L at diagnosis, which occurred following an episode of hypotensive shock. She fulfilled the diagnostic criteria of SM, with a bone marrow smear infiltration of 50–60% of atypical mast cells (MCs. She tested negative for the KIT D816V mutation, without any sign of organ damage (no B- or C-findings and only few mediator-related symptoms. She was treated with antihistamine alone and then with imatinib for the appearance of anemia. She maintained stable tryptase level and a very indolent clinical course for twenty-two months; then, she suddenly progressed to acute MCL with a serum tryptase level up to 12960 μg/L. The patient died due to haemorrhagic diathesis twenty-four months after diagnosis. This clinical case maybe represents an example of the chronic form of mast cell leukemia, described as unpredictable disease, in which the serum total tryptase level has confirmed itself as a reliable marker of mast cells burden regardless of the presence of other signs or symptoms.

    Full Text Available Background: Oral submucous fibrosis (OSMF is a debilitating, potentially cancerous oral condition. Although areca nut is the most important causative agent, it is also considered that the disease is immunologically mediated. Aim of the Study: To establish that autoimmunity and nutritional deficiency play a role in the etiopathogenesis of OSMF. Objectives of the Study: To show that serum immunoglobulin markers (immunoglobulin-G [IgG], immunoglobulin-A [IgA] and nutritional parameters such as total serum protein (TSP, Hemoglobin (Hb play a role in causing OSMF and also to correlate serum, salivary IgG, IgA levels in OSMF patients. Settings and Design: A case-control study was done with 50 patients (25 patients who were provisionally diagnosed as OSMF - Group I, and 25 patients who were chronic smokeless tobacco chewers and who did not have any intraoral lesion - Group II. Materials and Methods: Five milliliters of blood and saliva were collected from both the groups. Quantitative analysis of serum, and salivary IgG, IgA was done by turbidometric immunoassay. TSP and Hemoglobin (Hb were estimated by spectrophotometry. Statistical Analysis: Results were analyzed by independent samples t-test and one-way analysis of variance (ANOVA. Results: All patients of OSMF showed significant (P < 0.01 increase in serum IgG, IgA, and salivary IgG levels as compared to smokeless tobacco chewers. The salivary IgA levels showed a significant decrease in OSMF patients (P < 0.05. TSP and Hb levels showed significant (P < 0.01 decrease in OSMF patients as compared to smokeless tobacco chewers. Conclusion: The elevation of immunoglobulin levels supports the concept of autoimmunity. The decrease in TSP and Hb suggests that nutritional deficiency plays a defined role in the occurrence as well as a further progression of OSMF.

    Full Text Available BACKGROUND & AIMS: HBV-related acute-on-chronic liver failure (HBV-ACLF is a severe liver disease which results in a high mortality in China. To early predict the prognosis of the patients may prevent the complications and improve the survival. This study was aimed to develop a new prognostic index to estimate the survival related to HBV-ACLF. METHODS: Consecutive patients with HBV-ACLF were included in a prospective observational study. Serum Cystatin C concentrations were measured by using the particle-enhanced immunonephelometry assay. All of the patients were followed for at least 3 months. Cox regression analysis was carried out to identify which factors were predictive of mortality. The area under the receiver operating characteristic curve (AUC was used to evaluate the efficacy of the variates for early predicting mortality. RESULTS: Seventy-two patients with HBV-ACLF were recruited between January 2012 and January 2013. Thirty patients died (41.7% during 3-months followed up. Cox multivariate regression analysis identified serum cystatin C (CysC and total bilirubin (TBil were independent factors significantly (P < 0.01 associated with survival. Our results further showed that new prognostic index (PI combining serum CysC with TBil was a good indicator for predicting the mortality of patients with HBV-ACLF. Specifically, the PI had a higher accuracy than the CTP, MELD, or MELD-Na scoring for early prediction short-term survival of HBV-ACLF patients with normal levels of serum creatinine (Cr. The survival rate in low risk group (PI < 3.91 was 94.3%, which was markedly higher than those in the high-risk group (PI ≥ 3.91 (17.4%, P < 0.001. CONCLUSION: We developed a new prognostic index combining serum CysC with TBil which early predicted the short-term mortality of HBV-ACLF patients.

    Aim of this study is to find out clinical relevance of estimating PON1 arylesterase activity, total oxidative stress (TOS), nitric oxide (NO), and vitamin C levels in maternal serum for prediction of birth weight of newborn. We have investigated the PON1 arylesterase activity, TOS, NO, vitamin C, total protein, and albumin levels in 56 postnatal clinic patients having newborn weighing 2500 gm. Samples were collected immediately after delivery. PON1 arylesterase activity levels show significant decrease in cases as compared to controls (93.27 ± 13.76 kU/l vs. 112.77 ± 9.42 kU/l). Nitric oxide (nitrate + nitrite) levels are also found to be significantly decreased in cases with respect to controls (22.89 ± 2.65 umol/l vs. 24.73 ± 3.80 umol/l). Total oxidative stress is significantly increased in cases than in control subjects (23.34 ± 2.64 μmol H2O2 equiv./l vs. ± 21.43 ± 2.47 μmol H2O2 equiv/l). Vitamin C levels are also significantly decreased in cases as compared to controls (1.23 ± 0.25 mg/dl vs. 1.34 ± 0.28 mg/dl). Positive correlation between neonatal birth weight and maternal serum PON1 arylesterase activity (r = 0.682, p stress (r = -0.478, p levels with increased total oxidative stress in maternal serum may be considered as the additional risk factors for the development of low birth weight newborn.

    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.

    2000-04-01

    In a study of 130 first trimester cases of trisomy 21 and 959 controls we have shown that the median MoM for alpha-fetoprotein (AFP) is lower (0.82) and that for total human chorionic gonadotrophin (hCG) is higher (1.31) than in the control group. For AFP 15.3% of cases were below the 5th centile and for total hCG 19. 8% were above the 95th centile. The median shift observed for AFP and total hCG is poorer than that for pregnancy associated plasma protein-A (PAPP-A) or free beta-hCG and together with maternal age, AFP and total hCG could only be expected to detect 40% of cases. In combination with PAPP-A, total hCG would identify 52% of cases, somewhat less than the 67% observed with free beta-hCG and PAPP-A. However, we have demonstrated for total hCG a significant temporal change in median MoM with gestational age. Before 70 days the median MoM was less than 0.5, between 70 and 83 days this increased to 1.13, and between 84 and 97 days this increased to 1.52. This median shift has significant implications for interpreting previous studies and even more significant implications for detection rates. When population parameters specific to the gestational age in question are used, detection rates with total hCG and PAPP-A increase from 47% at 70-83 days to 60% at 84-97 days. This observation explains much of the confusion around total hCG in the first trimester and shows the importance of selecting analyte pairs and population parameters appropriate to the time in gestation when screening is performed.

    This study evaluates the relationship of blood osteoprotegerin (OPG) and receptor activator of nuclear κ-B ligand (RANKL) levels with coronary artery calcium (CAC) and cardiovascular risk factors in two studies of postmenopausal women. OPG, a marker of bone turnover, and its ligand, RANKL, may contribute to cardiovascular disease risk. We tested the hypothesis that serum OPG and RANKL levels were associated with CAC and cardiovascular disease risk factors among postmenopausal women in the Women On the Move through Activity and Nutrition Study (WOMAN Study; n = 86; mean [SD], age 58 [2.9] y) and replicated our findings in the Healthy Women Study (HWS; n = 205; mean [SD] age, 61 [2.3] y). Serum OPG, total RANKL, and CAC were measured at baseline and 48 months in the WOMAN Study and on the eighth postmenopausal visit in the HWS. In the WOMAN Study, higher OPG was associated with higher CAC, and higher total RANKL was associated with lower CAC and triglycerides. In the HWS, higher total RANKL was also associated with lower CAC and triglycerides. In logistic regression models adjusted for body mass index and triglycerides, the odds ratios (95% CIs) for CAC per unit increase in OPG were 1.78 (1.17-2.73) for the WOMAN Study and 1.02 (0.84-1.24) for the HWS, and the odds ratios (95% CIs) for CAC per unit increase in log total RANKL were 0.86 (0.64-1.17) for the WOMAN Study and 0.83 (0.72-0.96) for the HWS. The inverse association of total RANKL with CAC and triglycerides is a new finding and may have important implications given the increasing use of drugs that modify total RANKL and its receptor, receptor activator of nuclear κ-B.

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

    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.

    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.

    In this study, changes in serum total sialic acid (TSA) and lipid-bound sialic acid (LSA) levels were examined in chronically exposed rats to 7,12-dimethylbenz(a)anthracene (DMBA) and fluoride. This study demonstrated that the TSA, LSA levels increased more in DMBA-treated groups compared to the fluoride treated groups. The result obtained has shown that the harmful effect of DMBA which is also causing more cell membrane damage on human and animal health should be taken into consideration.

    Probability curves predicting oral food challenge test (OFC) results based on specific IgE levels are widely used to prevent serious allergic reactions. Although several confounding factors are known to affect probability curves, the main factors that affect OFC outcomes are currently unclear. We hypothesized that an increased total IgE level would reduce allergic reactivity. Medical records of 337 and 266 patients who underwent OFCs for 3.5 g boiled hen's egg white and 3.1 ml raw cow's milk, respectively, were examined retrospectively. We subdivided the patients into three groups based on total IgE levels and age by percentile (75th percentiles), and logistic regression analyses were performed on each group. Patients with higher total IgE levels were significantly less responsive. In addition, age did not significantly affect the OFC results. Therefore, total IgE levels should be taken into account when predicting OFC results based on food-specific IgE levels.

    Trace elements play an important role in the human central nervous system. Significant variations of the concentration of trace elements in body fluids may occur in neurodegenerative diseases. In the present work an investigation of the elemental composition of the serum, and the cerebrospinal fluid in amyotrophic lateral sclerosis patients and a control group was performed. For the analysis of the body fluids Total reflection X-ray Fluorescence (TXRF) spectrometry was used. The samples were taken during routine diagnostic procedures. Na, Mg, Cl, K, Ca, Cu, Zn, and Br were determined in both fluids. In order to validate the results of analysis a serum standard reference material was measured. A t-test was applied to check if the mean concentrations of the elements are different for ALS and the control group. For the serum samples higher values for Br were found in the ALS group, for the cerebrospinal fluid lower values of Na, Mg and Zn as well as higher Ca values were found in the ALS group compared to the control group.

    Alpha feto-protein (AFP) is a major plasma protein produced by the yolk sac and the liver during the fetal period. During the second trimester of pregnancy, APF and βhCG serum concentrations are commonly used for screening Down syndrome. AFP deficiency is rare (estimated to be 1/105 000 newborns) and only one sequence alteration has previously been reported in the AFP gene. We report a new mutation in exon 5 of the AFP gene, leading to a total absence of AFP on 2nd-trimester maternal serum screening for Down syndrome, confirmed on the amniotic fluid. Despite this, fetal development and birth were normal. After PCR-amplification, the whole AFP gene was sequenced. The new mutation was a guanine to adenine transition in position 543 creating a premature stop codon in position 181. In order to search for eventual modifications of the amniotic fluid profile, proteins were separated by electrophoresis and compared with 10 normal amniotic fluids sampled at the same developmental age (18 weeks). In the amniotic fluid of our patient albumin rate was reduced whereas alpha1 and beta protein fractions were increased, suggesting that AFP deficiency may modify the distribution of protein fractions. This observation emphasizes the complex molecular mechanisms of compensation of serum protein deficiency. Studies on other families with AFP deficiency are necessary to confirm this observation.

    Full Text Available Introduction. Hospital readmission within 30 days of discharge is a target for health care cost savings through the medicare Value Based Purchasing initiative. Because of this focus, hospitals and health systems are investing considerable resources into the identification of patients at risk of hospital readmission and designing interventions to reduce the rate of hospital readmission. Malnutrition is a known risk factor for hospital readmission.Materials and Methods. All medical patients 65 years of age or older discharged from Memorial Medical Center from January 1, 2012 to March 31, 2012 who had a determination of serum albumin level and total lymphocyte count on hospital admission were studied retrospectively. Admission serum albumin levels and total lymphocyte counts were used to classify the nutritional status of all patients in the study. Patients with a serum albumin less than 3.5 grams/dL and/or a TLC less than 1,500 cells per mm3 were classified as having protein energy malnutrition. The primary outcome investigated in this study was hospital readmission for any reason within 30 days of discharge.Results. The study population included 1,683 hospital discharges with an average age of 79 years. The majority of the patients were female (55.9% and had a DRG weight of 1.22 (0.68. 219 patients (13% were readmitted within 30 days of hospital discharge. Protein energy malnutrition was common in this population. Low albumin was found in 973 (58% patients and a low TLC was found in 1,152 (68% patients. Low albumin and low TLC was found in 709 (42% of patients. Kaplan–Meier analysis shows any laboratory evidence of PEM is a significant (p < 0.001 predictor of hospital readmission. Low serum albumin (p < 0.001 and TLC (p = 0.018 show similar trends. Cox proportional-hazards regression analysis showed low serum albumin (Hazard Ratio 3.27, 95% CI [2.30–4.63] and higher DRG weight (Hazard Ratio 1.19, 95% CI [1.03–1.38] to be significant

    The stability of total (t) and free (f) prostate-specific antigen (PSA) in male serum specimens stored at -70 degrees C or lower temperature for 4.7 to 4.9 years was studied. Until now, the stability of these analytes in serum has not been evaluated systematically beyond 2 years of storage at -70 degrees C. Aliquots of frozen serum were thawed in 2001 and 2006 and assayed for tPSA and fPSA using a Dade Behring Dimension(R) RxL analyzer and reagents. tPSA values ranged from 0.07 to 69.94 and 0.00 to 69.83 ng/mL in 2001 and 2006, respectively, whereas fPSA values for the tested specimens ranged from 0.02 to 5.72 and 0.00 to 5.92, respectively. Deming regression analyses showed agreement in assay values over time as tPSA values yielded a slope of 1.0112 and a y-intercept of 0.0195; fPSA values produced a slope 1.0538 and a y-intercept of -0.0442; f/tPSA values yielded a slope of 0.9631 and a y-intercept of 0.1195. A Bland-Altman analysis of the data demonstrated analyte and ratio stability over this time period. We conclude that serum, when collected properly and stored at -70 degrees C or lower temperature, may be used for tPSA and fPSA clinical studies for at least 5 years after collection.

    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, pcholesterol synthesis 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.

    A new highly fluorescent beta-diketone-europium chelate was synthesized and employed as a tracer to develop a time-resolved fluoroimmunoassay (TRFIA) for detection of serum total thyroxine (T4). The tetradentate beta-diketone chelator, 1,10-bis(thiophene-2'-yl)-4,4,5,5,6,6,7,7-octafluorodecane-1,3,8,10-tetraone (BTOT), was structurally composed of two units of thenoyltrifluoroacetone (TTA) derivatives but expressed fluorescence that was greatly enhanced, as compared to the original TTA molecules, in the presence of excess amount of Eu3+. The luminescence properties of the europium chelate of BTOT werestudied in aqueous solution. Chlorosulfonylation of BTOT afforded 1, 10-bis(5'-chlorosulfo-thiophene-2'-yl)-4,4,5,5,6,6,7,7-octafluorodecane-1,3,8,10-tetraone (BCTOT), which could be coupled to proteins (i.e., streptavidin or the BSA-T4 conjugate) and used as a tracer for TRFIA. Although the BCTOT-Eu complex could be detected at a very low level (approximately 1.07 x 10(-12) mol/L) in buffered aqueous solution (50 mmoVLTris-HCl; pH, 8.0), the application of the chelate label in direct serum T4 TRFIA experienced a problem of matrix interference, which was probably caused by some unknown chelating components in the samples as a result of the fact that the fluorescence of the BCTOT-Eu chelate was prone to quenching or enhancement by some chelating reagents. To remove this problem, an indirect serum T4 TRFIA was proposed with the use of BCTOT-Eu-labeled streptavidin (SA) as signal generation reagent. The concentrations of T4 in 27 human serums were determined by indirect T4 TRFIA, and the assay results correlated well with those obtained by commercial Coming-CLIA (r = 0.955) and Wallac-DELFIA (r 0.965).

    Sickle cell anemia (SCA) is a blood disorder that affects hemoglobin, the protein found in red blood cells that help carry oxygen throughout the body. In this work we have analyzed serum samples from patients with SCA by using total reflection X-ray fluorescence using synchrotron radiation (SRTXRF). The SRTXRF measurements were performed at the X-ray fluorescence beamline at Brazilian National Synchrotron Light Laboratory (LNLS), in Campinas, Sao Paulo using a polychromatic beam. We have studied forty-three patients aged 18-50 years old, suffering from SCA and Sixty healthy volunteers aged 18-60 years old. It was possible to determine the concentrations of the following elements: P, S, Cl, K, Ca, Fe, Cu, Zn, Br and Rb. Student's t-test was applied in order to check whether the two populations (CG x SCA) had the same mean values. It was observed that elemental concentration of P, Cl, K, Fe, Cu, Zn and Br differed significantly ({alpha} = 0.05) between groups of healthy subjects and SCA. The concentrations of K, Fe and Cu in the serum samples of patients with SCA were larger 15%, 120 % and 20 %, respectively, when compared with the CG. On the other hand, the concentrations of P (-20 %), Cl (-6 %), Zn (-25 %) and Br (-22 %) were smaller than the values determined for the control group. The serum level Cu/Zn ratio was significantly higher (60%) in the serum samples of patients with SCA group than the CG. So, the Cu/Zn ratio can be used as an adjuvant index in enhancement for diagnosis of SCA. There are evidences of an association among Fe, Cu, Zn and Cu/Zn in the SCA pathogenesis process. (author)

    Obesity is related to an increased risk of gastric cardia cancer. However, the influences of excess body weight and serum total cholesterol on the risk of gastric high-grade dysplasia have not been fully characterized.A case-control study was conducted to explore the relationships between body mass index (BMI), serum total cholesterol level, and the risk of gastric high-grade dysplasia in Chinese adults. A total of 893 consecutive patients with gastric high-grade dysplasia (537 men and 356 women) and 902 controls (543 men and 359 women) were enrolled from January 2000 to October 2015. Odds ratios (ORs) with 95% confidence intervals (CIs) were estimated, and a multivariate analysis was conducted.After adjusting for age, alcohol consumption, smoking status, family history of gastric cancer or esophageal cancer, and serum total cholesterol level, a BMI ranging from 27.5 to 29.9 was significantly related to an increased risk of gastric high-grade dysplasia in both men (adjusted OR = 1.87, 95% CI = 1.24-2.81) and women (adjusted OR = 2.72, 95% CI = 1.44-5.16). The 2 highest BMI categories (27.5-29.9 and ≥30.0) were identified as risk factors for gastric cardia high-grade dysplasia in both men (BMI = 27.5-29.9: adjusted OR = 1.78, 95% CI = 1.02-3.10; BMI ≥ 30.0: adjusted OR = 2.54, 95% CI = 1.27-5.08) and women (BMI = 27.5-29.9: adjusted OR = 2.88, 95% CI = 1.27-6.55; BMI ≥ 30.0: adjusted OR = 2.77, 95% CI = 1.36-5.64), whereas only a BMI ranging from 27.5 to 29.9 was a risk factor for gastric noncardia high-grade dysplasia in both men (adjusted OR = 1.98, 95% CI = 1.25-3.14) and women (adjusted OR = 2.88, 95% CI = 1.43-5.81). In addition, higher serum total cholesterol was associated with an increased risk of gastric noncardia high-grade dysplasia (adjusted OR = 1.83, 95% CI = 1.25-2.69) in women.Increased BMI was associated with an increased risk of gastric high-grade dysplasia in

    Introduction. Hospital readmission within 30 days of discharge is a target for health care cost savings through the medicare Value Based Purchasing initiative. Because of this focus, hospitals and health systems are investing considerable resources into the identification of patients at risk of hospital readmission and designing interventions to reduce the rate of hospital readmission. Malnutrition is a known risk factor for hospital readmission. Materials and Methods. All medical patients 65 years of age or older discharged from Memorial Medical Center from January 1, 2012 to March 31, 2012 who had a determination of serum albumin level and total lymphocyte count on hospital admission were studied retrospectively. Admission serum albumin levels and total lymphocyte counts were used to classify the nutritional status of all patients in the study. Patients with a serum albumin less than 3.5 grams/dL and/or a TLC less than 1,500 cells per mm3 were classified as having protein energy malnutrition. The primary outcome investigated in this study was hospital readmission for any reason within 30 days of discharge. Results. The study population included 1,683 hospital discharges with an average age of 79 years. The majority of the patients were female (55.9%) and had a DRG weight of 1.22 (0.68). 219 patients (13%) were readmitted within 30 days of hospital discharge. Protein energy malnutrition was common in this population. Low albumin was found in 973 (58%) patients and a low TLC was found in 1,152 (68%) patients. Low albumin and low TLC was found in 709 (42%) of patients. Kaplan-Meier analysis shows any laboratory evidence of PEM is a significant (p malnutrition.

    Iron, copper, zinc and selenium were determined directly in serum samples from healthy individuals ( n=33) and cancer patients ( n=27) by total reflection X-ray fluorescence spectrometry using the Compton peak as internal standard [L.M. Marcó P. et al., Spectrochim. Acta Part B 54 (1999) 1469-1480]. The standardized concentrations of these elements were used as input data for two-layer artificial neural networks trained with the generalized delta rule in order to classify such individuals according to their health status. Various artificial neural networks, comprising a linear function in the input layer, a hyperbolic tangent function in the hidden layer and a sigmoid function in the output layer, were evaluated for such a purpose. Of the networks studied, the (4:4:1) gave the highest estimation (98%) and prediction rates (94%). The latter demonstrates the potential of the total reflection X-ray fluorescence spectrometry/artificial neural network approach in clinical chemistry.

    Full Text Available OBJECTIVE: To evaluate if the digital rectal examination (DRE performed before determination of total serum prostate specific antigen (tPSA influences the levels of this protein. MATERIALS AND METHODS: Forty-eight men without a diagnosis of prostate pathology were assessed for tPSA levels, before and 30 minutes after DRE examination. Values of tPSA in the individuals' serum were measured by the electrochemoluminescence (ECLIA, in Roche's Elecys 1010 analyzer. RESULTS: DRE examination induced a modest elevation in tPSA values in 34 of the 48 men, with a variation in mean elevation from 2.19% in the age range ³ 70 years to 11.96% in the age range of 60-69 years. Additionally, moderate decreases in values were detected in 11 individuals and 3 did not present any alteration following the procedure. Differences in mean values of tPSA, pre- and post-DRE were not statistically significant, neither in the total sample of individuals or in the age range groups. CONCLUSION: DRE examination does not significantly influence the tPSA values in individuals under study.

    Results from prospective cohort studies on the association between dietary total fat and fatty acids intake and risk of breast cancer remain controversial. Pertinent prospective cohort studies were identified by a search of Embase and PubMed from inception to September 2015. Study-specific relative risks (RRs) with 95% confidence intervals were pooled using a random-effect model. Between-study heterogeneity and publication bias were assessed, and sensitivity analysis was conducted. Twenty-four independent studies on dietary total fat and fatty acids intake and seven studies on serum fatty acids were included. The pooled RR of breast cancer for the highest vs. lowest category of dietary total fat intake was 1.10 (1.02-1.19); however, no association was observed in studies adjusting for traditional risk factors of breast cancer. No association was observed between animal fat, vegetable fat, saturated fatty acids (SFA), monounsaturated fatty acids (MUFA), polyunsaturated fatty acids (PUFA), n-3 PUFA, n-6 PUFA, eicosapentaenoic acid, docosahexaenoic acid, alpha-linolenic acid, oleic acid, linoleic acid and arachidonic acid and risk of breast cancer. The pooled RRs of breast cancer for the highest vs. lowest category of serum SFA, MUFA, PUFA, n-3 PUFA and n-6 PUFA were 1.00 (0.78-1.28), 1.41 (0.99-2.03), 0.59 (0.27-1.30), 0.81 (0.60-1.10) and 0.84 (0.60-1.18), respectively. Results from this meta-analysis suggested that dietary total fat and fatty acids might be not associated with risk of breast cancer.

    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.

    Systemic inflammation participates to the complex healing process occurring after major surgery, thus directly affecting the surgical outcome and patient recovery. Total plasma N-glycome might be an indicator of inflammation after major surgery, as well as an anti-inflammatory therapy response marker, since protein glycosylation plays an essential role in the inflammatory cascade. Therefore, we assessed the effects of surgery on the total plasma N-glycome and the association with self-administration of postoperative morphine in two cohorts of patients that underwent major abdominal surgery. We found that plasma N-glycome undergoes significant changes one day after surgery and intensifies one day later, thus indicating a systemic physiological response. In particular, we observed the increase of bisialylated biantennary glycan, A2G2S[3,6]2, 12 hours after surgery, which progressively increased until 48 postoperative hours. Most changes occurred 24 hours after surgery with the decrease of most core-fucosylated biantennary structures, as well as the increase in sialylated tetraantennary and FA3G3S[3,3,3]3 structures. Moreover, we observed a progressive increase of sialylated triantennary and tetraantennary structures two days after surgery, with a concomitant decrease of the structures containing bisecting N-acetylglucosamine along with bi- and trisialylated triantennary glycans. We did not find any statistically significant association between morphine consumption and plasma N-glycome.

In total, 280 commercial layers were randomly divided into 4 groups (G1, G2, G3 and G4. At five days of age, birds from groups G1 received approximately 107 colony forming units (CFU of SGDcobS; meanwhile birds from group G2 and G3 received the same dose of SGNalr and SG∆cobS∆cbiA, respectively. Birds from G4 were not infected. At 24 hours before (DBI and 24 hours after (1 DAI, and three (3 DAI, five (5 DAI, seven (7 DAI ten (10 DAI, and fifteen (15 DAI days after the infection, 10 birds of each group were humanely killed and blood samples collected to hematological and serum tests. Samples of liver, spleen, thymus, bursa of Fabricius, kidney and heart were also collected for the histological examination. Birds inoculated with SGDcobS and SGNalr showed similar alterations in hemogram, blood serum components and anatomopathologic exams. On the other hand, the exams of birds inoculated with SG∆cobS∆cbiA strain were similar to those of the uninfected birds. However, changes could be noticed in levels of uric acid and cholesterol during the course of the infection of birds from G3. Decrease in levels of light IgG 3 DAI was also observed in birds from this group. Pyknosis in kidney cells was a microscopic alteration found in birds from G3. Further studies must be done to verify if these alterations will not interfere in the performance of the vaccinate birds with SG∆cobS∆cbiA strain.

    We here describe a new spectrophotometric method for measuring total bilirubin in serum. The method is based on the cleavage of bilirubin giving formaldehyde which further reacts with diazotized 3-methyl-2-benzothiazolinone hydrazone hydrochloride giving blue colored solution with maximum absorbance at 630 nm. Sensitivity of the developed method was compared with Jendrassik-Grof assay procedure and its applicability has been tested with human serum samples. Good correlation was attained between both methods giving slope of 0.994, intercept 0.015, and R2 = 0.997. Beers law obeyed in the range of 0.068-17.2 μM with good linearity, absorbance y = 0.044 Cbil + 0.003. Relative standard deviation was 0.006872, within day precision ranged 0.3-1.2% and day-to-day precision ranged 1-6%. Recovery of the method varied from 97 to 102%. The proposed method has higher sensitivity with less interference. The obtained product was extracted and was spectrally characterized for structural confirmation with FT-IR, 1H NMR.

    This study was aimed to determine the rate of occupational asthma (OA) in workers at a rose extracting plant. Specific clinical tests of 52 workers, randomly chosen from four local rose extracting plants, were statistically compared with the test results of 30 local control subjects of similar age and sex as the plant workers, but who had never worked in such a plant. There were no significant differences in pulmonary function tests (FVC, FEV1, FEV1/FVC, PEFR) between the control and test groups. Significantly higher serum total IgE values (p rose allergen (Rosa domescena) was positive for 53.84% in the test subjects whereas only 5.33% positive test results were seen in the control group. We have demonstrated the involvement of Rosa domescena pollen in occupational allergy, through IgE-mediated hypersensitivity. It was concluded that the workers of a rose oil extracting plant are more susceptible to the rose pollens.

    IMPORTANCE Despite performing total thyroidectomy (TT), postoperative radioactive iodine (RAI) imaging often demonstrates the presence of residual thyroid tissue within the operative bed. OBJECTIVE To measure the extent of TT using postoperative RAI imaging and assessing serum thyroglobulin (Tg) level for patients with differentiated thyroid carcinoma (DTC). DESIGN, SETTING, AND PARTICIPANTS We evaluated 245 patients undergoing TT for clinically staged cT1-3N0M0 DTC, who underwent diagnostic postoperative RAI imaging. INTERVENTIONS Total thyroidectomy. MAIN OUTCOMES AND MEASURES On the basis of quantitative measurements, RAI uptake (RAIU) in the thyroid bed of 0.2% of administered activity was selected as the cutpoint to determine the presence or absence of thyroid remnant. RESULTS By postoperative RAI imaging, TT in 106 patients (43%) resulted in RAIU of less than 0.2%. In the remaining 139 patients (57%), there was measurable iodine-avid thyroid tissue and/or tumor in the thyroid bed (n = 117 [84%]), the neck (n = 4 [3%]), or both (n = 18 [13%]). For the entire study population, mean 24-hour RAIU was 0.62%. Stimulated serum Tg levels were obtained in 232 of 245 patients (95%). Measurable stimulated Tg level (≥1 ng/mL) (to convert to micrograms per liter, multiply by 1) was found in 26 of 102 patients (25%) without thyroid remnant and in 87of 133 patients (65%) with thyroid remnant (P < .001). CONCLUSIONS AND RELEVANCE A goal of postthyroidectomy RAIU of less than 0.2% helps maximize the likelihood of an unmeasurable postoperative Tg level, potentially simplifying follow-up evaluation and reducing the use of postoperative RAI in order to facilitate surveillance.

    The purpose of this study was to evaluate if long-term (6 months) treatment with lasofoxifene (LAS), a new selective estrogen receptor modulator (SERM), can protect against age-related changes in bone mass and bone strength in intact aged male rats. Sprague-Dawley male rats at 15 months of age were treated (daily oral gavage) with either vehicle (n = 12) or LAS at 0.01 mg/kg per day (n = 12) or 0.1 mg/kg per day (n = 11) for 6 months. A group of 15 rats was necropsied at 15 months of age and served as basal controls. No significant change was found in body weight between basal and vehicle controls. However, an age-related increase in fat body mass (+42%) and decrease in lean body mass (-8.5%) was observed in controls. Compared with vehicle controls, LAS at both doses significantly decreased body weight and fat body mass but did not affect lean body mass. No significant difference was found in prostate wet weight among all groups. Total serum cholesterol was significantly decreased in all LAS-treated rats compared with both the basal and the vehicle controls. Both doses of LAS treatment completely prevented the age-related increase in serum osteocalcin. Peripheral quantitative computerized tomography (pQCT) analysis at the distal femoral metaphysis indicated that the age-related decrease in total density, trabecular density, and cortical thickness was completely prevented by treatment with LAS at 0.01 mg/kg per day or 0.1 mg/kg per day. Histomorphometric analysis of proximal tibial cancellous bone showed an age-related decrease in trabecular bone volume (TBV; -46%), trabecular number (Tb.N), wall thickness (W.Th), mineral apposition rate, and bone formation rate-tissue area referent. Moreover, an age-related increase in trabecular separation (Tb.Sp) and eroded surface was observed. LAS at 0.01 mg/kg per day or 0.1 mg/kg per day completely prevented these age-related changes in bone mass, bone structure, and bone turnover. Similarly, the age-related decrease in TBV

    Venous blood was collected on two mornings from seven healthy volunteers using the standard Scandinavian procedure (fasting, sitting and no tourniquet) and serum Na, K, ASAT, ALAT, CK, LD and total protein were assayed. Then ethanol (0.75 g/kg body weight) was given on three consecutive evenings and the subsequent observed values 1, 3, 15, 38, 62 and 110 h post-ethanol were compared with the morning values. The mean component/total protein ratios dropped 14% for ASAT and 19% for ALAT 62 and 15 h post-ethanol, respectively. CK rose 17% at 3 h and dropped 17% at 62 h. However, the absolute values of ASAT, ALAT and CK did not change significantly. The only significant post-ethanol changes occurred in Na +2.14 mmol/l at 1 h (p less than 0.01), K -0.24 mmol/l at 3 h (p less than 0.05) and +0.26 mmol/l at 15 h (p less than 0.05), and LD +31 IU/l at 15 h (p less than 0.05) and +25 IU/l at 110 h (p less than 0.01). In one series, the total protein concentration dropped 4.57 g/l at 110 h post ethanol (p less than 0.001) but this drop was not reproducible in two additional series. It is concluded that moderate (social) ethanol consumption does not produce clinically significant effects on the components analysed. Also it may be misleading to express results as component/total protein ratios.

    Chronic periodontitis (CP) and rheumatoid arthritis (RA) appear to share many pathologic features. Oxygen metabolism has an important role in the pathogenesis of both CP and RA. The aim of this study is to evaluate the relationship between these two chronic inflammatory diseases with regard to antioxidant and oxidant status. A total of 80 participants were divided into four groups of 20 each: group RA-CP (patients with RA and CP), group RA (periodontally healthy patients with RA), group CP (systemically healthy patients with CP), and group C (periodontally and systemically healthy volunteers) were included in the study. After assessment of periodontal measurements, gingival crevicular fluid (GCF) samples were taken at one incisor, premolar, and molar tooth and stored with serum samples at -80°C for the antioxidant/oxidant assay. Although all clinical measurements in groups RA-CP and CP were statistically higher compared to those of C and RA groups (P 0.05). GCF total oxidant status (TOS) values of CP and RA-CP groups were higher than those of the RA group (P oxidative stress index (OSI) values of the RA-CP group were higher than those of the RA group (P 0.05). Local OSI values in groups with patients with CP were higher, whereas systemic OSI values showed no difference among the groups. The presence of RA seems not to affect local and systemic OSI values in patients with CP.

    The pharmacokinetics of gestodene (GEST) and ethinylestradiol (EE2) were determined in 14 healthy women (age 18 to 32 years) during a treatment period of three months with a new tri-step combination oral contraceptive (Milvane). Prior to this treatment period, the same women received a single administration of a coated tablet containing 0.1 mg GEST together with 0.03 mg EE2. There was a wash-out phase of one week between both treatments. Following single dose administration, a mean terminal half-life of 18 h was observed for GEST. The total clearance was 0.9 ml x min-1 x kg-1 and the volume of distribution was 84 l. During a treatment cycle, GEST levels in the serum accumulated by a factor of 8 as compared to single dose administration. Steady-state drug levels were reached during the second half of each cycle. As compared to single dose administration, the following changes were observed for GEST at the end of treatment cycles one and three: prolonged terminal half-life (20 to 22 h), reduced total (0.16 ml x min-1 x kg-1) and free clearance (ca. 27 ml x min-1 x kg-1), reduced volume of distribution (ca. 18 l). A concomitant EE2-induced increase in the SHBG concentrations by a factor of three as compared to pretreatment values was observed during a treatment cycle and appeared to be mainly responsible for the changes in the pharmacokinetics of GEST. Marked changes were also seen for the serum protein binding of GEST. After single dose administration, the free fraction of GEST was 1.3% and the fractions bound to SHBG and albumin were 69.4% and 29.3%, respectively. At the end of cycle one, the free fraction was only 0.6% and the fractions bound to SHBG and albumin were 81.4% and 18.0%, respectively. There was no difference in corresponding pharmacokinetic parameters and in the serum protein binding of GEST at the end of cycles one and three. On the last day of treatment cycles one and three, the AUC(0-4h) values of EE2 were 299.2 and 278.1 pg x ml-1 x h, respectively

    To examine trends of uncontrolled total serum cholesterol, treatment and control in a Mediterranean region (Campania). We considered and compared the data collected as part of "Montecorvino Rovella Project" 1988-1989 and cross-sectional data from the two phases of the "VIP Project-Valle dell'Irno Prevenzione": 1998-1999 (1(st) phase) and 2008-2009 (2(nd) phase), in the 35-74-year-old-population. Data show a reduction of mean cholesterolemia in the last twenty years of 7.3 mg/dL for men and unchanged values for women. In the three surveys the mean values for serum cholesterol are in men: 205.2 ± 47.1 mg/dL (1988/89), 200 ± 38.9 mg/dL (1998/99) and 197.9 ± 40.2 mg/dL (2008/09); in the women: 203.1 ± 42.5 mg/dL (1988/89), 198.9 ± 37.9 mg/dL (1998/99) and 203.3 ± 39.3 mg/dL (2008/09). Prevalence of uncontrolled high cholesterol ≥ 240 mg/dL for men decreased from 20.8% (1988/89) to 14.3% (1998/99) and 13.9% (2008/9), P = 0.002; for women the values decreased from 19.9% (1988/89), to 18.2% (1998/99) and 18.1% (2008/09), P = 0.007. Is statistically increased the number of patients treated and those treated to target. Encouraging increases in awareness, treatment, and control of hypercholesterolemia occurred from 1988 through 2008. Nevertheless, control of hypercholesterolemia remains poor.

    Full Text Available Abstract Background Few data have been published on the association of variables of the insulin resistance syndrome and serum total homocysteine (tHcy, a putative risk factor for cardiovascular morbidity, in representative samples of total populations or in Hispanic Americans. Methods To describe the distributions of serum tHcy concentration and variables associated with insulin resistance in Mexican American men and to assess their association, data from a cross-sectional survey of a large national sample, the Third National Health and Nutrition Examination Survey were analyzed. Analyses were restricted to Mexican American men aged 40–74 years with data on glycated hemoglobin (%, body mass index (BMI, body fat distribution, HDL cholesterol, fasting serum insulin, serum triglycerides and serum tHcy concentrations. Results Cumulative distributions of serum tHcy shifted to the right with increasing age. Log serum tHcy was not associated with prevalence of diagnosed diabetes mellitus or glycated hemoglobin percent or other risk factors other than age. Log serum tHcy concentration showed borderline significant (p = 0.049 positive association with fasting serum insulin concentration independent of age and BMI, only in men aged 60–74. Conclusion No consistent association of tHcy with diabetes prevalence or variables of the insulin resistance syndrome were found in Mexican American men aged 40–74 years. Further research is needed on the associations of serum tHcy concentration with insulin resistance and other components of the insulin resistance syndrome in persons of varying ethnicity.

    We sought the lowest serum total 25-hydroxyvitamin D (t-25OHD) values in geographic areas with four seasons and investigated whether the calculation of serum free 25-hydroxyvitamin D (f-25OHD) could provide additional information on vitamin D status. This is a representative, cross-sectional study restricted to a sampling period at the end of winter, using a non-probability, stratified sample of the adult community-dwelling Hungarian population (n = 882). We measured t-25OHD, vitamin D binding protein (DBP), parathyroid hormone (PTH), and albumin levels. f-25OHD concentrations were calculated. We assessed environmental factors that could affect vitamin D levels and diseases possibly related to vitamin D deficiency. Mean t-25OHD values of the total population were 41.3 ± 20.6 nmol/L. t-25OHD levels were below 75, 50, and 30 nmol/L in 97, 77, and 34 % of participants not receiving vitamin D supplementation, respectively. t-25OHD values weakly positively correlated with DBP (r = 0.174; p = 0.000), strongly with f-25OHD (r = 0.70; p = 0.000). The association between t-25OHD and f-25OHD and between t-25OHD and PTH were non-linear (p squared term = 0.0004 and 0.004, respectively). t-25OHD levels were not affected by gender, age, place of residence; however, they were related to body mass index, sunbed sessions, and tropical travel. In contrast, f-25OHD levels were different in males and females but were not related to obesity. t- and f-25OHD were lower among people with cardiovascular diseases (p = 0.012). Nearly the entire Hungarian population is vitamin D insufficient at the end of winter. The use of t-25OHD could show a spurious association with obesity; however, it does not reflect the obvious sex difference.

    In this study, levels of malondialdehyde (MDA), which is a significant product of lipid peroxidation (LPO), total oxidant status (TOS), total antioxidant capacity (TAOC), and the oxidative stress index (OSI), a novel value as a marker of periodontal disease activity, are investigated in serum and saliva from patients with chronic (CP) and generalized aggressive (GAgP) periodontitis. A total of 98 patients (33 with CP, 35 patients with GAgP, and 30 periodontally healthy controls) enrolled in the study. After clinical measurements and sample collection, the MDA level, TOS, and TAOC were measured by high-performance liquid chromatography and a novel automatic colorimetric method. The OSI was calculated as [(TOS/TAOC) × 100]. Although the salivary MDA levels and serum and salivary TOS and OSI values were significantly higher in the periodontitis groups than in the control group (P 0.05). Furthermore, oxidative stress parameters were higher in the GAgP group than in the CP group (except the serum and salivary MDA levels and serum TAOC). Significant positive and negative correlations were observed between periodontal parameters and the MDA levels and TOS, TAOC, and OSI values (except serum MDA) (P <0.05). The present findings suggest that an increased TOS and decreased TAOC, rather than LPO, play important roles in the pathology of periodontitis and are closely associated with clinical periodontal status. Furthermore, the OSI may be a useful and practical parameter for evaluating periodontal disease activity.

  16. Holding thermal receipt paper and eating food after using hand sanitizer results in high serum bioactive and urine total levels of bisphenol A (BPA.

    Full Text Available Bisphenol A (BPA is an endocrine disrupting environmental contaminant used in a wide variety of products, and BPA metabolites are found in almost everyone's urine, suggesting widespread exposure from multiple sources. Regulatory agencies estimate that virtually all BPA exposure is from food and beverage packaging. However, free BPA is applied to the outer layer of thermal receipt paper present in very high (∼20 mg BPA/g paper quantities as a print developer. Not taken into account when considering thermal paper as a source of BPA exposure is that some commonly used hand sanitizers, as well as other skin care products, contain mixtures of dermal penetration enhancing chemicals that can increase by up to 100 fold the dermal absorption of lipophilic compounds such as BPA. We found that when men and women held thermal receipt paper immediately after using a hand sanitizer with penetration enhancing chemicals, significant free BPA was transferred to their hands and then to French fries that were eaten, and the combination of dermal and oral BPA absorption led to a rapid and dramatic average maximum increase (Cmax in unconjugated (bioactive BPA of ∼7 ng/mL in serum and ∼20 µg total BPA/g creatinine in urine within 90 min. The default method used by regulatory agencies to test for hazards posed by chemicals is intra-gastric gavage. For BPA this approach results in less than 1% of the administered dose being bioavailable in blood. It also ignores dermal absorption as well as sublingual absorption in the mouth that both bypass first-pass liver metabolism. The elevated levels of BPA that we observed due to holding thermal paper after using a product containing dermal penetration enhancing chemicals have been related to an increased risk for a wide range of developmental abnormalities as well as diseases in adults.

    Full Text Available Introduction: Pathogenic role of free radicals are well known in various metabolic diseases. They originate from internal and external sources of body. Essential roles of antioxidant defense system for cellular redox regulation and free radical scavenging activity were described in this study. Many in vitro investigations have shown that turmeric (TE and carrot seed extract (CSE exhibits to possess antioxidant activities. In this study, we evaluated the antioxidant potentials of ethanolic TE and CSE based on in vivo experiment in the rats. Methods: Animals were assigned to six groups: the 1st and 2nd groups were control groups and 2nd group received 0.2 ml dimethyl sulphoxide as vehicle treated group; other four experimental groups received different doses of TE (100, 200 mg/kg b.w. and CSE (200, 400 mg/kg b.w. by gavages, respectively for a period of one month. The indicators of oxidative stress, lipids peroxidation, markers of hepatocyte injury and biliary function markers were measured. Results: The levels of superoxide dismutase, catalase, and glutathione peroxidase were significantly stimulated in the hepatic tissue of treatment groups. The malondialdehyde contents of liver tissue were significantly reduced in the groups fed with TE and CSE. Serum levels of alanine aminotransferase, aspartate aminotransferase and alkaline phosphatase, in treated groups were found to be significantly decreased, whereas albumin and total protein increased as compared to the control groups (P<0.05. Conclusion: this study showed that the regular intake of TE and CSE through the diet can improve antioxidant status and inhibit peroxidation activity in the liver tissue so that using these extracts may protect tissue oxidative stress.

    Terrorist radiological attacks or nuclear accidents could expose large numbers of people to ionizing radiation. In mass-casualty radiological incidents early medical-management requires triage tools for first-responders to quantitatively identify individuals exposed to life-threatening radiation doses and for early initiation (i.e., within one day after radiation exposure) of cytokine therapy for treatment of bone marrow acute radiation syndrome. Herein, we present results from 30 rhesus macaques total-body irradiated (TBI) to a broad dose range of 1-8.5 Gy with {sup 60}Co {gamma}-rays (0.55 Gy min{sup -1}) and demonstrate dose- and time-dependent changes in blood of C-reactive protein (CRP), serum amyloid A (SAA), and interleukin 6 (IL-6) measured by enzyme linked immunosorbent assay (ELISA). CRP and SAA dose-response results are consistent with {approx}1 Gy and {approx}0.2 Gy thresholds for photon-exposure at 24 h after TBI, respectively. Highly significant elevations of CRP and SAA (p = 0.00017 and p = 0.0024, respectively) were found in animal plasma at 6 h after all TBI doses suggesting their potential use as early-phase biodosimeters. Results also show that the dynamics and content of CRP and SAA levels reflect the course and severity of the acute radiation sickness (ARS) and may function as prognostic indicators of ARS outcome. These results demonstrate proof-of-concept that these radiation-responsive proteins show promise as a complementary approach to conventional biodosimetry for early assessment of radiation exposures and may also contribute as diagnostic indices in the medical management of radiation accidents.

    There are limited data on serum total light chain (sTLC) in lymphoma and its relative role on the outcome of diffuse large B cell lymphoma (DLBCL) patients. Blood samples from 46 cases newly diagnosed with DLBCL were collected consecutively during chemotherapy to detect sTLC, IgG, IgA, and IgM levels. Clinical data and survival outcomes were analyzed according to the results of sTLC measurements. In summary, 22 patients (47.8 %) had abnormal k or λ light chain, respectively, and 6 patients (13.0 %) had both abnormal k and λ light chains before chemotherapy. Patients with elevated k light chain more frequently displayed multiple extra-nodal organ involvement (P = 0.01) and had an inferior overall survival (OS) (P = 0.041) and progression-free survival (PFS) (P = 0.044) compared to patients with normal level of k light chain. Furthermore, patients with elevated level of both k and λ also exhibited significant association with shorter OS (P = 0.002) and PFS (P = 0.009). Both elevated k alone and concurrent elevated k and λ had independent adverse effects on PFS (P = 0.031 and P = 0.019, respectively). sTLC level was reduced gradually by treatment in this study and reached the lowest point after the fourth cycle of chemotherapy, which was consistent with the disease behavior during chemotherapy. Considering the small sample size of this study, these results should be confirmed in a larger prospective study.

    Plasminogen activator inhibitor (PAI-1) is induced in the vasculature and secreted into the vascular lumen in response to inflammation and oxidative stress. We have previously reported a fivefold increase in plasma PAI-1 from rats exposed to 708 kPa hyperbaric air. In the current study we assess the potential of human serum total PAI-1 as a biomarker for stress in compressed air diving. Eleven recreational divers, nine males and two females, completed four 2 h hyperbaric air exposures to 280 kPa in a pressure chamber over a period of 2 weeks. The air pressure corresponds to a diving depth of 18 m in water. Serum was collected before the study and again 3 h 30 min after completion of each hyperbaric exposure. All samples were taken in the afternoon to minimize the contribution of circadian variation. The analysis revealed no change in serum total PAI-1 after hyperbaric exposures within the group of divers (P = 0.064), but significant interindividual differences persisted throughout the study (P PAI-1. In conclusion, compressed air exposure to 280 kPa does not affect serum total PAI-1, and significant interindividual variation in PAI-1 levels may limit its usefulness as a biomarker. This does, however, not give a complete answer regarding PAI-1 in physiologically stressful dives. Further studies with different exposures and timing are needed for that.

    Full Text Available Reduced nicotinamide adenine dinucleotide (NADH dehydrogenase subunit 2 237 leucine/methionine (ND2-237 Leu/Met polymorphism, is reportedly associated with longevity in the Japanese population. The ND2-237Met genotype may exert resistance to atherogenic diseases, such as myocardial infarction or cerebrovascular disorders. To investigate whether ND2-237 Leu/Met polymorphism is associated with yearly changes in serum lipid levels, we conducted a longitudinal study of 107 healthy Japanese male subjects. Analysis of covariance revealed that the interaction between the ND2-237 Leu/Met genotypes and habitual drinking was significantly associated with yearly changes in serum total cholesterol (TC and low-density lipoprotein cholesterol (LDLC levels (p0.036 and p0.006, respectively. In multiple regression analysis, daily drinking was significantly and positively associated with yearly changes in serum LDLC levels in men with ND2-237Met (p0.026. After adjusting for covariates, yearly changes in serum LDLC levels were significantly lower in non-daily drinkers with ND2-237Met than in those with ND2-237Leu (p0.047. These results suggest that ND2-237Met has a beneficial impact on yearly changes in serum LDLC in non-daily drinkers but not in daily drinkers.

    Patients with anorexia nervosa (AN) are GH resistant, with elevated GH levels and low serum levels of total insulin-like growth factor I (IGF-I). IGF-I action is modulated by IGF-binding proteins (IGFBPs), and a variety of catabolic states has been characterized by the presence of increased IGFBP-3 proteolysis. The present study was performed to examine the levels of free IGFs in AN and to clarify whether AN is associated with increased IGFBP-3 proteolytic activity. In 24 patients and 10 age-matched controls, the fasting serum concentrations of free IGF-I and -II were measured using ultrafiltration by centrifugation. In addition, GH, GH-binding protein, total IGFs, IGFBP-1 to -4, and IGFBP-3 proteolytic activity were measured. The IGFBPs were measured by both immunoassays and Western ligand blotting. Twelve of the patients were restudied 3 months after a minor increase in body mass index. In AN, the levels of GH-binding protein, free and total IGF-I, free IGF-II, and IGFBP-3 were significantly reduced; total IGF-II, IGFBP-2, and IGFBP-4 levels were unchanged; and IGFBP-1 was increased. No increased IGFBP-3 proteolytic activity could be detected in AN. In conclusion, the mechanisms responsible for the adaption of the GH-IGF-IGFBP axis in AN may be different from other catabolic conditions, because the low levels of free and total IGF-I in AN are not associated with increased IGFBP-3 proteolysis.

    A fast, accurate and precise ion chromatography method with pulsed amperometric detection was applied to evaluate a variety of parameters affecting the determination of total iodine in serum and urine of 81 subjects, including 56 obese and 25 healthy Polish children. The sample pretreatment methods were carried out in a closed system and with the assistance of microwaves. Both alkaline and acidic digestion procedures were developed and optimized to find the simplest combination of reagents and the appropriate parameters for digestion that would allow for the fastest, least time consuming and most cost-effective way of analysis. A good correlation between the certified and the measured concentrations was achieved. The best recoveries (96.8% for urine and 98.8% for serum samples) were achieved using 1ml of 25% tetramethylammonium hydroxide solution within 6min for 0.1ml of serum/urine samples. Using 0.5ml of 65% nitric acid solution the best recovery (95.3%) was obtained when 7min of effective digestion time was used. Freeze-thaw stability and long-term stability were checked. After 24 weeks 14.7% loss of iodine in urine, and 10.9% in serum samples occurred. For urine samples, better correlation (R(2)=0.9891) of various sample preparation procedures (alkaline digestion and application of OnGuard RP cartidges) was obtained. Significantly lower iodide content was found in samples taken from obese children. Serum iodine content in obese children was markedly variable in comparison with the healthy group, whereas the difference was less evident when urine samples were analyzed. The mean content in serum was 59.12±8.86μg/L, and in urine 98.26±25.93 for obese children when samples were prepared by the use of optimized alkaline digestion reinforced by microwaves. In healthy children the mean content in serum was 82.58±6.01μg/L, and in urine 145.76±31.44μg/L.

    The aim of the study was to examine the impact of the leucine7 to proline7 (Leu7Pro) polymorphism of the NPY gene on postprandial (PP) lipemia, post-heparin plasma lipoprotein lipase (LPL) and hepatic lipase (HL) activities, and the response of serum lipids to a reduced fat diet. Seven middle-aged obese subjects with Leu7Pro genotype were matched with seven subjects with Leu7Leu genotype for gender, age, apolipoprotein E phenotype and BMI. These 14 subjects participated in the oral 8 h fat tolerance test. Sixty-eight slightly obese middle-aged subjects (10 with the Leu7Pro genotype) had participated in intervention studies and consumed a reduced fat diet for 8 weeks. There were no statistically significant differences in PP areas under the curve of plasma total triglycerides (TG), chylomicron TG, VLDL-TG or insulin between the genotype groups. The TG-to-cholesterol (C) ratio in VLDL was significantly lower in the subjects with Leu7Pro genotype compared to those with the Leu7Leu genotype at time points 30 min and 1 h in the fat tolerance test. Heparin-induced activities of LPL or HL or the response of serum total or LDL-C to the reduced fat diet did not differ between the groups. The NPY genotype neither affects the magnitude of postprandial lipemia induced by a fat tolerance test nor the response of serum total lipids or lipids in different lipoprotein classes to the reduced fat diet. However, this preliminary study suggests that there might be compositional differences in the lipoprotein particles between the genotype groups that affect postprandial lipid metabolism.

    In this study, we assessed the effects of inorganic and organic pollutants [As, Cu, Fe, Mn, Pb, Zn, PAHs (11 compounds) and total phenols] from a panel of biomarkers [O2, H2O2, thiobarbituric acid reactive substances (TBARS), carbonyl proteins (RCO), superoxide dismutase (SOD), catalase (CAT), glutathione peroxidase (GPx) and total cytochrome P450 activities] evaluated in the Snout Scraping (SS), Serum (S) and Peripheral Blood Cells (PBC) of the Morelet's crocodile (Crocodylus moreletii) inhabiting the reference locality (Lake Mocu) and polluted locality (Champoton River) using Principal Component Analysis (PCA). In male crocodiles from the reference site, only H2O2 in PBC was related to levels of fluoranthene on the Keel of Caudal Scales (KCS), but, in females, no association was detected. In contrast, a sex-linked response was detected in specimens from the polluted locality. Levels of benzo[a]pyrene, benzo[a]anthracene, chrysene, pyrene, phenanthrene, acenaphthene, Zn, Cu, and Pb in KCS of the female crocodil were related to the oxidative stress biomarkers on PBC, incluing the total CYP450 activity and levels of O2, H2O2 in serum. However, in male crocodiles, the oxidative stress in SS and in the serum (TBARS, RCO, CAT, GPx), and SOD in PBC was related to As, Pb, Cu, Fe, and benzo[a]pyrene water concentrations and to the burdens of As, Fe, Mn, indeno[1,2,3cd]pyrene in KCS. These results confirm the usefulness of minimal or non-invasive methods of evaluating the oxidative stress response for the environmental monitoring program on the wild Morelet's crocodile that is subject to special protection in Mexican guidelines.

    In development of serum total thyroxin TRFIA using the surface second-antibody (S-Ab) as separation agent, a significant bias of measurement caused by matrix interference when the surface S-Ab shows a relatively low binding capacity for primary anti-T4 monoclonal antibody (McAb) is studied. The bias ranges from 10% to 78%, depending on the matrix of individual samples and the binding capacity of the surface S-Ab prepared. So, a new separation system based on the use of a highly active surface streptavidin and biotinylated anti-T4 McAb is employed. The results indicate

    Alterations in energy balance and feeding behavior and the subsequent high frequency of obesity are hallmarks of 2 chromosomal diseases: the Prader-Willi syndrome (PWS) and the Down syndrome (DS). Leptin, an important regulator of food intake and energy homeostasis, circulates in 2 forms: a free, therefore active, fraction and a fraction bound to the soluble leptin receptor, whose bioavailability consequently participates in the regulation of leptin action. To investigate the possible role of the free-bound leptin balance in the pathogenesis of obesity in PWS and DS, we enrolled 7 obese women with DS, 5 obese women with PWS, 7 obese women, and 7 normal-weight healthy control women. Basal hormonal concentrations, total and free leptin levels, and leptin receptors levels were measured in plasma samples obtained from the 4 groups. No significant differences were observed in the hormonal milieu. Women with DS exhibited lower total leptin concentrations (Pobese controls, then resembling the profile peculiar to normal-weight control women. At variance, subjects with PWS did not differ from obese controls regarding both leptin and leptin receptor levels. Our data suggest that, whereas subjects with PWS have a leptin assessment corresponding to their degree of obesity, subjects with DS may have a defect in the secretion of leptin that could at least partially account for this form of syndromal obesity.

    A comparative assessment of excess storage iron distribution in the liver, heart, spleen and pancreas of β-thalassemia major (β-ΤΜ) patients has been carried out using magnetic resonance imaging (MRI) relaxation times T2*. The β-ΤΜ patients (8-40 years, 11 males, 9 females) had variable serum ferritin levels (394-5603 μg/L) and were treated with deferoxamine (n = 10), deferiprone (n = 5) and deferoxamine/deferiprone combination (n = 5). MRI T2* assessment revealed that excess iron is not proportionally distributed among the organs but is stored at different concentrations in each organ and the distribution is different for each β-ΤΜ patient. There is random variation in the distribution of excess storage iron from normal to severe levels in each organ among the β-ΤΜ patients by comparison to the same organs of ten normal volunteers. The correlation of serum ferritin with T2* was for spleen (r = -0.81), liver (r = -0.63), pancreas (r = -0.33) and none with heart. Similar trend was observed in the correlation of liver T2* with the T2* of spleen (r = 0.62), pancreas (r = 0.61) and none with heart. These studies contradict previous assumptions that serum ferritin and liver iron concentration is proportional to the total body iron stores in β-ΤΜ and especially cardiac iron load. The random variation in the concentration of iron in the organs of β-ΤΜ patients appears to be related to the chelation protocol, organ function, genetic, dietary, pharmacological and other factors. Monitoring of the iron load for all the organs is recommended for each β-ΤΜ patient.

    Full Text Available O objetivo deste trabalho foi estudar o padrão de variação da atividade sérica da fosfatase alcalina total (tALP, da isoenzima óssea da fosfatase alcalina (BALP e da fosfatase ácida resistente ao tartarato (TRAP, assim como a variação da concentração dos minerais séricos durante o processo de cicatrização de fraturas ósseas no cão. A variação sérica destes marcadores do metabolismo ósseo foi avaliada em nove cães com fraturas diafisárias fechadas de ossos longos, submetidas a tratamento cirúrgico para osteosíntese. Durante o período pós-operatório, sete animais evoluíram no sentido de uma normal união óssea, sendo que dois deles desenvolveram um processo de não união óssea. Foram observados, relativamente à BALP, valores de actividade sérica mais elevados e com diferença estatística (P<0,05 no grupo de animais que evoluiu no sentido de uma normal união óssea, comparativamente ao grupo de animais que evoluiu no sentido do processo de não união. No grupo de animais que evoluiu para a completa união óssea foram, adicionalmente, observados valores diminuidos (P<0,05 da atividade sérica da TRAP, até ao dia 60 do período pós-operatório seguido de uma elevação estatisticamente significativa após este período. Em conclusão, os biomarcadores do metabolismo ósseo poderão vir a constituir um método auxiliar de diagnóstico na monitorização do processo de cicatrização de fracturas ósseas, possibilitando, a detecção precoce de complicações pós-operatórias.

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.

    Full Text Available Objectives: To evaluate associations of preoperative total prostate specific antigen (PSA to free testosterone (FT, the PSA/FT index ratio, with features of pathology prostate cancer (PCA and to investigate its prognostic potential in clustering the PCA population. Patients and methods: After excluding criteria, the records of 220 patients who underwent radical prostatectomy (RP were retrospectively reviewed. Serum samples of PSA, total testosterone (TT and FT were collected at 8.00 A.M., one month after biopsies and before RP. The PSA/FT ratio was computed in the population of patients who were clustered in groups according to ranking intervals of the PSA/FT ratio which identified at least 4 clusters which were coded as A, B, C, and D. The independent associations of the PSA/FT index ratio were assessed by statistical methods and a two-sided P < 0.05 was considered to indicate statistical significance. Results: TT correlated to FT which was a significant predictor of PSA in the population of patients who were subsequently clustered, according to increasing interval values of the PSA/FT index ratio, in groups that showed a stronger linear association of FT with PSA. The PSA/FT index ratio significantly associated with pathology features of prostate cancer such as pathology Gleason score (pGS, invasion of the seminal vesicles (pT3b, proportion of positive cores (P+ and proportion of cancer involving the volume of the prostate. In the population of patients, TT, PSA/FT index ratio and P+ independently associated with pGS ≥ 7 and pT3b; moreover, the odds ratio (OR of the PSA/FT index ratio resulted 9.11 which was stronger than TT (OR = 1.11 and P+ (OR = 8.84. In the PCA population, TT, PSA/FT index ratio and P+ also independently associated with pT3b PCA; interestingly, the OR of PSA/FT index resulted 54.91 which was stronger than TT (OR = 1.31 and P+ (26.43. Conclusions: Preoperative PSA/FT index ratio is an independent strong factor which

    Data on the effect of combined genetic polymorphisms, involved in folate metabolism, on the concentration of serum folate after folic acid supplementation are scarce. Therefore, we investigated the impact of seven gene polymorphisms on the concentration of serum folate and p-tHcy in healthy subjects after short-term folic acid supplementation. In a randomized, double blind, crossover study, apparently healthy subjects were given either 0.8 mg folic acid per day (n = 46) or placebo (n = 45) for 14 days. The washout period was 14 days. Fasting blood samples were collected on day 1, 15, 30 and 45. Data on subjects on folic acid supplementation (n = 91) and on placebo (n = 45) were used for the statistical analysis. The concentration of serum folate increased higher in subjects with higher age (53.5 ± 7.0 years) than in subjects with lower age (24.3 ± 3.2 years) after folic acid supplementation (p = 0.006). The baseline concentration of serum folate in subjects with polymorphism combination, reduced folate carrier protein, RFC1-80 GA and methylenetetrahydrofolate reductase, MTHFR677 CT+TT, was lower than RFC1-80 AA and MTHFR677 CT+TT (p = 0.002). After folic acid supplementation, a higher increase in the concentration of serum folate was detected in subjects with polymorphism combination RFC1-80 GA and MTHFR677 CC than RFC1-80 GG and MTHFR CT+TT combination (p folic acid supplementation, in subjects with combined polymorphisms in methylenetetrahydrofolate dehydrogenase, MTHFD1-1958 and MTHFR-677 genes, the concentration of p-tHcy was changed (p = 0.002). The combination of RFC1-80 and MTHFR-677 polymorphisms had a profound affect on the concentration of serum folate in healthy subjects before and after folic acid supplementation.

    Full Text Available Total thyroidectomy is a surgery that removes all the thyroid tissue from the patient. The suspect of cancer in a thyroid nodule is the most frequent indication and it is presume when previous fine needle puncture is positive or a goiter has significant volume increase or symptomes. Less frequent indications are hyperthyroidism when it is refractory to treatment with Iodine 131 or it is contraindicated, and in cases of symptomatic thyroiditis. The thyroid gland has an important anatomic relation whith the inferior laryngeal nerve and the parathyroid glands, for this reason it is imperative to perform extremely meticulous dissection to recognize each one of these elements and ensure their preservation. It is also essential to maintain strict hemostasis, in order to avoid any postoperative bleeding that could lead to a suffocating neck hematoma, feared complication that represents a surgical emergency and endangers the patient’s life.It is essential to run a formal technique, without skipping steps, and maintain prudence and patience that should rule any surgical act.

    Paracoccidioides brasiliensis is the fungus agent of paracoccidioidomycosis, a deep-seated systemic infection of humans. Up to the moment no vaccine has still been reported. The potential of gamma radiation for pathogens attenuation and vaccine development was explored in this work. In our laboratory we developed radioattenuated yeast cells of P. brasiliensis and the aim of the present work was to evaluate the antibody production dynamics in mice immunized with this cells. Were analyzed the IgG antibodies titers as well as the type of response by analyzing the IgG1 and IgG2a antibody pattern in the course of infection. The mice were divided in two groups that were immunized one time and two times respectively. The mice infected with the virulent P. brasiliensis showed a high level of antibody production while the infection with the radioattenuated yeast did not significantly change the antibody level. The level of IgG raised in both immunized groups after the challenge. In the group immunized one time was not observed a significant difference between the levels of both subclasses when compared with the control. After the challenge of the group immunized two times the IgG2a levels increased significantly when analyzed 90 days post challenge. We concluded that a pattern related to the disease control was apparent in the group submitted to two immunizations. The mice had not developed a totally polarized pattern of TH1/TH2 response but a trend to a TH1 response was evident. (author)

    Objective To determine the effect of pre-operative serum albumin (ALB) level and total lymphocyte count (TLC) on the prognosis of hip fracture in the elderly patients. Methods Clinical data of 640 elderly patients (over 60 years old) with hip fracture undergoing surgical treatment in our department from July 2006 to December 2010 were collected and retrospectively analyzed in this study. Their serum ALB level and TLC were recorded at admission. Their hospitalization time, in-hospital complications, and mortality at hospital and at 3 and 12 months after surgery were analyzed. Cox regression analysis was carried out on these data. The clinical significance of serum ALB level and TLC was evaluated in the prediction of prognosis. Results Among the 640 patients, those with lower serum ALB level accounted for 44.2%(283), and those with lower TLC accounted for 68.0%(435). The patients with lower albumin and lower TLC had higher incidence of postoperative complications (13.3%), and higher mortalities at hospital (4.3%), 3-month (6.7%) and 12-month (16.7%) post-operatively compared to the patients who had normal values of the 2 laboratory parameters (all P<0.05). Cox regression analysis indicated that serum ALB and TLC were predictive factors for mortality risk in the elderly with hip fracture. Conclusion Malnutrition at admission indicates poor clinical outcome after surgical treatment in the elderly patients with hip fracture. Lower serum ALB level and TLC are regarded as predictive factors for malnutrition and poor prognosis in these patients.%目的:探讨术前血清白蛋白(ALB)及淋巴细胞总数(TLC)改变对老年髋部骨折预后的影响。方法回顾性地分析2006年7月至2010年12月在解放军总医院行手术治疗老年髋部骨折的640例患者的临床资料。分别于入院时检测ALB和TLC。临床随访指标包括患者住院时间、住院并发症、住院死亡率、术后3个月死亡率、术后12个月死亡率。将所得资

    Asthma is a serious disease that causes an impaired quality of life, significant financial loss, and death. The incidence and severity of asthma and the mortality it causes have increased during the last 10 y. Because the reasons for this are not known, studies using experimental animals are needed to determine if environmental factors (e.g., inhaled pollutants) may be important for the increased incidence of asthma.

    1979-01-01

    Full Text Available Total serum lactate dehydrogenase activity in cases of myocar-dial infarct is difficult to interpret as abnormal values can occur in diseases of liver, kidney and skeletal muscle. The estimation of its isoenzymes is of better diagnostic help because of its tissue specificity. Serum LDH isoenzymes were studied in patients o f myocardial infarction and results are quantitated by densitometry. As LDH 1 represents serum hydroxybutyric dehydrogenase when 2-oxylbutyrate is used as substrate, serum hydroxybutyric dehydro-genase was also estimated in above patients. Greater specificity in diagnosis is achieved with SHBDH because of its myocardial nature and lower incidence of false positive results.

    Oxidative stress inhibits albumin's ability to complex with cobalt. Feline serum-cobalt binding has not been described. The objective was to develop a cobalt binding test for use with feline serum, and correlate the results with other biochemical and cellular constituents in blood, and with clinical diseases of cats. A colorimetric test of cobalt binding, based on the oxidation-reduction reaction of Co(+2) and dithiothreitol, was developed using feline serum. The test was used to measure cobalt binding in stored serum from 176 cats presented to the University of Illinois Veterinary Teaching Hospital for a variety of disease conditions. Time-matched hematology and biochemical data, and clinical information, were obtained from the medical record of each cat and correlated with the serum-cobalt binding results. Serial dilution of feline serum with phosphate-buffered saline resulted in a highly linear decrease in serum-cobalt binding (r(2)  = .9984). Serum-cobalt binding of the clinical samples also correlated with albumin concentrations in a stepwise linear regression model (r(2)  = .425), and both cobalt binding and albumin were significantly decreased in cases of inflammation. Albumin and cobalt binding also shared significant correlations with several erythron variables, and serum concentration of total calcium and bilirubin. The correlation of cobalt binding measured by a colorimetric test with albumin concentration in the clinical samples and with serum dilution is consistent with feline albumin-cobalt complex formation. Hypoalbuminemia is the likely cause of reduced serum-cobalt binding in inflammation and the correlations observed between cobalt binding and other variables. © 2015 American Society for Veterinary Clinical Pathology.

    Background: Serum protein profiling patterns can reflect the pathological state of a patient and therefore may be useful for clinical diagnostics. Here, we present results from a pilot study of proteomic expression patterns in hemodialysis patients designed to evaluate the range of serum proteomic alterations in this population. Methods: Surface-Enhanced Laser Desorption/Ionization Time-of-Flight Mass Spectrometry (SELDI-TOFMS) was used to analyze serum obtained from patients on periodic hemodialysis treatment and healthy controls. Serum samples from patients and controls were first fractionated into six eluants on a strong anion exchange column, followed by application to four array chemistries representing cation exchange, anion exchange, metal affinity and hydrophobic surfaces. A total of 144 SELDI-TOF-MS spectra were obtained from each serum sample. Results: The overall profiles of the patient and control samples were consistent and reproducible. However, 30 well-defined protein differences were observed; 15 proteins were elevated and 15 were decreased in patients compared to controls. Serum from one patient exhibited novel protein peaks suggesting possible additional changes due to a secondary disease process. Conclusion: SELDI-TOF-MS demonstrated dramatic serum protein profile differences between patients and controls. Similarity in protein profiles among dialysis patients suggests that patient physiological responses to end-stage renal disease and/or dialysis therapy have a major effect on serum protein profiles.

    Objective To observe the influence of lift-thrust reinforcing-reducing manipulations of acupuncture on serum ferritin (SF) content and total iron binding capacity (TIBC) in blood-deficiency syndrome rabbits so as to study its underlying mechanisms. Methods Sixty Japanese white rabbits were randomized into blank control,model. Acupuncture needle-retaining, reinforcing-manipulation (reinforcing) and reducing-manipulation (reducing) groups (n = 12 in each group). Blood-deficiency syndrome model was duplicated by bleeding (about 10 mL/time, once every other day, for 5 times) and food restriction (half of the normal quantity). Bilateral "Zusanli" (ST 36) were punctured by using filiform needles. The needles were not lifted and thrust for rabbits of the needle-retaining group, but lifted and thrust for 15 min for rabbits of the reinforcing and reducing groups. The treatment was given once every other day, 10 times altogether. Serum SF and TIBC levels were assayed by radioimmunoassay. Results Following modeling, compared to the blank control group, serum SF content was decreased significantly (P0. 05). Conclusion Both reinforcing and reducing manipulation of acupuncture of "2usanli"(ST 36) can up-regulate serum SF content and down-regulate TIBC level in blood-deficiency syndrome rabbits, which may contribute to their effects in improving blood-deficiency syndrome and has no significant difference.%目的:通过观察针刺提插补泻“足三里”穴对血虚证家兔血清铁蛋白(SF)和总铁结合力(TIBC)的影响,探讨提插补泻与效应的关系.方法:将60只家兔随机分为5组:空白组、模型组、留针组、补法组、泻法组,每组12只.采用放血加限食法制造血虚证模型.针刺各组每次治疗15 min,隔天治疗1次,共计10次.采用放射免疫法检测血清SF及TIBC.结果:针刺治疗后第17天,补法、泻法两组的SF与针刺前相比明显升高(P<0.05),TIBC明显降低(P<0.05);针刺治疗后第32天,

    目的:通过建立脑血流低灌注模型,观察老龄大鼠脑血流的变化以及在脑血流低灌注下血清中总胆固醇(Total cholesterol,TC)和高密度脂蛋白(High density lipoprotein,HDL)的动态变化.方法:采用持久性双侧颈总动脉结扎法(2Vo)致老龄大鼠脑血流灌注不足,测定术后7、14、21、28d大鼠脑皮质血流;检测、比较术后不同时间段大鼠血清中TC和HDL浓度差异.结果:术后第14天大鼠脑颞区血流出现明显减少;术后21、28d大鼠脑局部皮质血管有再生侧支形成,大鼠脑颞区血流仍未恢复;术后第14天血清中HDL、TC含量明显高于假手术组(P<0.05),随着缺血时间延长,又逐渐降低.结论:血清TC和HDL浓度在脑缺血灌注不足的不同时间段经历了先增强后减弱的动态变化,提示脑血流低灌注老龄大鼠因大脑血流灌注不足可出现体内胆固醇代谢失衡并出现应激调节现象.%Objective: To investigate the change of cortical blood flow and the dynamic changes of serum total cholesterol(TC ) and high density lipoprotein(HDL) in brains of aging rat during cerebral ischemic injury. Methods:The model of aging rats with cerebral hy-poperfusion was successfully constructed by persistent bilateral common carotid artery ligation(2V0). The cortical blood flow and the concentration of serum TC and HDL at different time points were determined and compared. Results: Compared with the sham-operated group,the temporal blood flow was significantly decreased in 14 d group. But the collateral vessels were gradually regenerated and formed in local brain,while the temporal blood flow was restored in 21 d and 28 d group. The concentration of HDL and TC was significantly higher in 14 d group than in the sham-operated group (P<0.05), and both of them were decreased with the extention of ischemia time. Conclusions:The serum TC and HDL concentration undergo dynamic changes-increasing first and then decreasing during the process

    Adipokines are cytokines derived from adipose tissue. Recently it has been established that adipokines are closely linked to the pathophysiology of not only metabolic diseases, such as diabetes mellitus, obesity, and atherosclerosis, but also to inflammation and immune diseases. In this study we measured serum levels of adipokines in patients with acute Kawasaki disease to investigate the role of adipokines in the pathophysiology of Kawasaki disease. Serum resistin, high-molecular-weight (HMW) adiponectin, leptin, and visfatin levels were measured by enzyme-linked immunosorbent assay in a total of 117 subjects: 56 patients with acute Kawasaki disease, 30 healthy children, and 31 patients with acute infectious diseases. Serum resistin levels in patients with Kawasaki disease were significantly higher than those of healthy children and patients with acute infectious diseases. In contrast, mean serum HMW adiponectin, leptin, and visfatin levels in patients with Kawasaki disease exhibited no statistically significant differences compared with those in healthy children and patients with infectious diseases. Serum resistin levels decreased significantly after administration of intravenous immune globulin. Serum resistin levels on admission were significantly higher in nonresponders compared with responders to intravenous immune globulin therapy. A multivariate model revealed that C-reactive protein was a factor that was significantly related to elevated serum resistin level in patients with Kawasaki disease. In patients with Kawasaki disease, serum resistin levels were elevated, but decreased to nearly normal after intravenous administration of immune globulin. In contrast, serum HMW adiponectin, leptin, and visfatin levels showed no statistically significant changes. These findings suggest that resistin plays an important role, while other adipokines do not play a major role, in the pathogenesis of Kawasaki disease.

    As many as 2247 patients with different clinical forms of diphtheria were examined. Antidiphtheric serum (ADS) was administered in 1556 children, the dosage being determined by condition of the patient. Serum sickness developed at day 7 to 9 in 24 (1.5%); 10 patients were found to run a mild course, 14--moderately severe. 6 patients had allergic reactions: 3--to antibiotic (penicillin), urticaria type, 1--to pertussoid-tetanic anatoxin, 2 had pollinosis-type reaction. Thus, serum sickness has practical value, which fact requires a detailed allergic history together with skin tests to be performed before the administration of ADS.

    To investigate the role of CCR5 in immunological pathogenesis ofseasonal contact dermatitis, the expression of CCR5 on peripheral blood lymphocytes before and after being cultured in 22 cases of seasonal contact dermatitis (SCD), 25 cases of non-season allergic contact dermatitis(NSCD) was detected by immunofluorescent marker-flowcytometry; total serum IgE was detected by RIA. The result showed that: (1) The positive rate of total serum IgE in SCD was higher than that of NSCD( P<0.01) and health group ( P<0.01). (2) Compare to health group, the number of CD4+CCR5+ lymphocytes of SCD was lower before culture( P<0.01) and was higher after culture ( P < 0.01 ) but still lower than that of NSCD( P<0.01) . (3) The numbers of CD4+CDR5+ lym phocytes after culture in both SCD and NSCD was higher than those before culture (both P<0.01 ), but the number was lower in the group( P<0.01 ). Our results indicated that the capacity of the lymphocyte differentiating to Thl type cell might be impaired which might be related to the IgE-mediated late-phase reaction in SCD.%为探讨外周血淋巴细胞趋化因子受体5(CCR5)在季节性接触性皮炎发病中的作用,检测了22例季节性接触性皮炎患者,25例非季节性变应性接触性皮炎患者及20名健康对照外周血淋巴细胞在培养前、后CCR5的表达(流式细胞仪 法)及血清总IgE水平(IRMA法)。结果表明:季节组的血清总IgE阳性率高于非季节组(P<0.01);季节组的CD4+ CCR5+细胞在培养前低于对照组(P<0.01),而在培养后则高于对照组(P<0.01),但低于非季节组(P<0.05);季节 组和非季节组的CD4+CCR5+细胞在培养后均高于培养前(均P<0.01)。提示季节性接触性皮炎患者的淋巴细胞向Th1 方向分化的能力可能减弱,并可能与IgE介导的迟发相反应有关。

    The unbound fraction of many drugs appears to be the therapeutically active component. However, the major problem encountered in following unbound serum gold (UBSG) concentration during chrysotherapy has been the ability to quantitate such a small quantity of gold reliably without matrix interference. The methodology detailed here overcomes these difficulties and provides an effective means of monitoring the UBSG fraction during chrysotherapy. We have observed that the unbound fraction of gold dissipates quickly after gold sodium thiomalate administration and constitutes less than 2% of the total serum gold concentration.

    Full Text Available A infecção pelo vírus da imunodeficiência dos felinos (VIF apresenta um curso prolongado, caracterizado por uma fase aguda, em que ocorre a replicação viral no organismo hospedeiro, seguida de um período de menor replicação, no qual o animal é praticamente assintomático. Anos depois, no estádio final da infecção, desenvolve-se a síndrome da imunodeficiência dos felinos. Alguns animais infectados podem desenvolver hipergamaglobulinemia do tipo policlonal, principalmente na fase crônica ou final da infecção. Este fato tem sido atribuído a um distúrbio na produção de citocinas, causado pela infecção viral de linfócitos T CD4+. Não obstante, pouco se sabe a respeito das concentrações de proteínas séricas, especificamente gamaglobulinas, na fase aguda da infecção pelo VIF. Objetivando esclarecer isto, procedeu-se à determinação das proteínas séricas de dez felinos, SRD de ambos os sexos, infectados aos 7 meses de idade com o VIF (clade B, antes da infecção e 4, 8 e 12 meses após. A infecção pelo VIF foi confirmada pela soroconversão, com a presença de anticorpos específicos, pesquisados por meio da técnica de imunoadsorção enzimática (ELISA e pela demonstração de material genético do vírus (PCR. Outros dez felinos VIF-, da mesma faixa etária foram mantidos como controle. Previamente à infecção experimental, todos os felinos eram negativos ao VIF, fato comprovado pela ausência de anticorpos específicos.

    Cadmium (Cd) is an industrial pollutant and carcinogenic metal. Most in vitro Cd toxicity studies have been carried out in various cell lines cultured in 10% fetal bovine serum (FBS) containing medium. In this report, we compared the toxic effect of Cd (0-300 microM) on cell growth, total RNA, total proteins, and antioxidant enzymes in rat normal liver cells cultured in medium with 10% FBS or commercially available serum-free medium for 4 or 8 hours. With Cd concentration at above 100 microM, the total levels of RNA, protein and cell growth decreased in serum-containing medium, while their levels increased in serum-free medium compared to the controls. The glutathione peroxidase and glutathione reductase levels were lower in serum-free medium than in serum-containing medium, indicating less oxidative stress in cells grown in serum-free medium. These results clearly suggest that Cd showed higher toxicity to liver cells grown in serum-containing medium in comparison to commercially available serum-free medium. It is speculated that albumin and other substances present in commercial serum-free medium chelated Cd and thereby protected these cells against Cd toxicity. Even under in vivo conditions, cadmium enters into various organs after passing through blood which contains serum. Based on these studies, it appears that media containing serum may be ideal for in vivo toxicity correlation studies with animal cells.

    OBJECTIVE: To evaluate the effect of L-carnitine on serum total level of homocysteine (tHcy) in patients undergoing maintenance hemodialysis. METHODS: 60 patients undergoing maintenance hemodialysis were randomly divided into two groups (treatment group and control group): the patients in the treatment group were injected i.v. with 1.0 g of L-carnitine for 12 weeks, and those in the control group were injected i.v. with 5 mL normal saline for 12 weeks. Meanwhile,the healthy people were involved as normal control group(n =20) . tHcy was detected by ELISA method; the fasting insulin was detected by radio- immunity method. Fasting blood glucose, total cholesterol, triglyeride, HDL and LDL were detected by routine method. The reciprocal of the multiplication product between fasting blood glucose and insulin concentration were computed as insulin sensitivity index(ISI) . RESULTS: After treatment for 12 weeks, the treatment group showed increased ISI but significantly reduced tHcy (P< 0.05); however, no significant differences of ISI.tHcy were noted in the control group before and after treatment. CONCLUSION: Insulin resistance and high tHcy present in patients undergoing maintenance hemodialysis can be reversed by L - carnitine.%目的:探讨左卡尼汀对维持性血液透析患者血清总同型半胱氨酸(tHcy)水平的影响.方法:60例维持性血液透析患者随机分为2组,治疗组每次血液透析后静脉注射左卡尼汀1.0 g,对照组静脉注射5 mL生理盐水,疗程12周.另设20例门诊健康体检者为正常对照组.采用酶联免疫吸附(ELISA)法测定tHcy,放射免疫法测定空腹胰岛素,常规方法检测空腹血糖、总胆固醇、总甘油三酯、高密度脂蛋白、低密度脂蛋白,以空腹血糖与空腹胰岛素浓度水平乘积的倒数作为胰岛素敏感指数(ISI).结果:与治疗前比较,治疗组治疗12周后ISI明显提高,tHcy明显下降(P<0.05),对照组治疗前、后ISI、tHcy

    Hypercholes erolaemia is a modifiable risk factor in atherosclerosis. Women lose their relative protection against coronory heart disease at menopause because of changed lipid profile due to oestrogen deficiency. Total serum cholesterol was estimated in 82 healthy postmenopausal women in the age group of 46-72 years (51.5 +/- 7.39). Thirty five healthy pre-menopausal women in the age group of 18-38 years (29.5 +/- 6.4) served as controls. The mean serum cholesterol concentration was significantly higher in the postmenopausal group compared to control group (178.5 +/- 39.8 Vs 155.4 +/- 24 mg/dl; P < 0.01). Serum cholesterol concentration in the study group was not related to social class, dietary habit and obesity.

    The use of retroviral vectors for gene therapy applications demands high titer preparations and stringent quality standards. However, the manufacturing of these vectors still represents a highly challenging task due to the low productivity of the cell lines and reduced stability of the vector infectivity, particularly under serum-free conditions. With the objective of understanding the major limitations of retroviral vector production under serum deprivation, a thorough study of viral production kinetics, vector characterization and cell growth and metabolic behavior was conducted, for 293 FLEX 18 and Te Fly Ga 18 producer cell lines using different serum concentrations. The reduction of serum supplementation in the culture medium resulted in pronounced decreases in cell productivity of infectious vector, up to ninefold in 293 FLEX 18 cells and sevenfold in Te Fly Ga 18 cells. Total particles productivity was maintained, as assessed by measuring viral RNA; therefore, the decrease in infectious vector production could be attributed to higher defective particles output. The absence of the serum lipid fraction was found to be the major cause for this decrease in cell viral productivity. The use of delipidated serum confirmed the requirement of serum lipids, particularly cholesterol, as its supplementation not only allowed the total recovery of viral titers as well as additional production increments in both cell lines when comparing with the standard 10% (v/v) FBS supplementation. This work identified lower production ratios of infectious particles/total particles as the main restraint of retroviral vector production under serum deprivation; this is of the utmost importance concerning the clinical efficacy of the viral preparations. Lipids were confirmed as the key serum component correlated with the production of infective retroviral vectors and this knowledge can be used to efficiently design medium supplementation strategies for serum-free production.

    Full Text Available Continuing improvements in analytical technology along with an increased interest in performing comprehensive, quantitative metabolic profiling, is leading to increased interest pressures within the metabolomics community to develop centralized metabolite reference resources for certain clinically important biofluids, such as cerebrospinal fluid, urine and blood. As part of an ongoing effort to systematically characterize the human metabolome through the Human Metabolome Project, we have undertaken the task of characterizing the human serum metabolome. In doing so, we have combined targeted and non-targeted NMR, GC-MS and LC-MS methods with computer-aided literature mining to identify and quantify a comprehensive, if not absolutely complete, set of metabolites commonly detected and quantified (with today's technology in the human serum metabolome. Our use of multiple metabolomics platforms and technologies allowed us to substantially enhance the level of metabolome coverage while critically assessing the relative strengths and weaknesses of these platforms or technologies. Tables containing the complete set of 4229 confirmed and highly probable human serum compounds, their concentrations, related literature references and links to their known disease associations are freely available at http://www.serummetabolome.ca.

    The binding of doxorubicin, iododoxorubicin, daunorubicin, epirubicin, pirarubicin, zorubicin, aclarubicin, and mitoxantrone to 600 microM human serum albumin and 50 microM alpha 1-acid glycoprotein was studied by ultrafiltration at 37 degrees C and pH 7.4. Anthracycline concentrations (total and free) were determined by high-performance liquid chromatography (HPLC) with fluorometric detection. Binding to albumin (600 microM) varied from 61% (daunorubicin) to 94% (iododoxorubicin). The binding to alpha 1-acid glycoprotein (50 microM) was more variable, ranging from 31% (epirubicin) to 64% (zorubicin), and was essentially related to the hydrophobicity of the derivatives. Simulations showed that the total serum binding varied over a broad range from 71% (doxorubicin) to 96% (iododoxorubicin). We recently reported that the binding to lipoproteins of a series of eight anthracycline analogues could be ascribed to chemicophysical determinants of lipophilicity [2]. The present study was conducted to evaluate in vitro the contribution of albumin and alpha 1-acid glycoprotein to the total serum binding of these drugs.

    Full Text Available BACKGROUND: Major Depressive Disorder (MDD is a common disorder, with a lifetime prevalence of about 15 percent, perhaps as high as 25 percent for women. The etiology of MDD is too complex to be explained totally by a single social, developmental, or biological theory. A variety of factors appear to work together to cause or precipitate depressive disorders. Various functions have been reported for trace elements such as zink in recovery or exacerbation of depression. METHODS: In this experimental study, we studied 46 patients with MDD based on DSM IV criteria, among the patients referred to mental disorders clininc of Noor Hospital. Twenty Patients were men and 26 were women. Thirty two volunteers of general population were evaluated for depression with Beck depression test who did not show any depressive symptoms with this test. A blood sample of 5cc was obtained from each person and the serum zinc concentration was measured. Data gathered and analyzed with SPSS, logistic regression and chi-squar tests. RESULTS: Serum zinc concentrations were 74 to 130 mg/dl in men and 60 to 128 mg/dl in women of control group. Serum zinc concentration was 30 to 60 mg/dl in depressive patients that it was lower in women than men. The difference between serum zinc concentrations of normal and depressive persons was meaningful (P = 0.02. CONCLUSION: In our study, the serum concentration of zinc was about half of normal value. This study replicates previous findings that major depressed subjects show significantly lowered serum zinc concentration. KEYWORDS: Depression, zinc.

    1982-03-30

    In order to clarify the role of tryptophan in the patogenesis of senile cataract, we have studied the serum total and free levels of tryptophan in cataract patients as compared with age and sex-matched controls, and the urinary excretion of 10 metabolites after oral load of the amino acid. This excretion increases in the cataract group both as total per cent and as kynurenine. No difference has been found in the free and total serum tryptophan between normal subjects and cataract patients. A possible role of the kynurenines in the pathogenesis of senile cataract is suggested.

    Serum sickness-like reaction is a rare immunological condition which may develop following exposure to certain drugs such as penicillins, cephalosporins, and trimethoprim-sulfamethoxazole, among many others. It is described classically as a type III hypersensitivity response to heterologous proteins. Its true mechanism is still unclear. We present a case of serum sickness-like reaction to clarithromycin, a commonly prescribed drug for the treatment of respiratory tract infections. The patient had been taking this drug for 3 days when she experienced generalized body aches, rash, arthralgia, and shortness of breath, prompting presentation to the emergency department. Laboratory studies showed decreased C4 and total complement with a slightly elevated sedimentation rate. After exclusion of other possible causes, the diagnosis of serum sickness-like reaction was made. The patient responded well to nonsteroidal antiinflammatory medication, antihistamines, and a short, tapering dose of steroids. To our knowledge, serum sickness-like reaction to clarithromycin has never been reported previously. This case emphasizes the need for increased clinical awareness of such an adverse outcome to clarithromycin use.

    Much has still to be learned about the molecular mechanisms of depression. This study aims to gain insight into contributing mechanisms by identifying serum proteins related to major depressive disorder (MDD) in a large psychiatric cohort study. Our sample consisted of 1589 participants of the Netherlands Study of Depression and Anxiety, comprising 687 individuals with current MDD (cMDD), 482 individuals with remitted MDD (rMDD) and 420 controls. We studied the relationship between MDD status and the levels of 171 serum proteins detected on a multi-analyte profiling platform using adjusted linear regression models. Pooled analyses of two independent validation cohorts (totaling 78 MDD cases and 156 controls) was carried out to validate our top markers. Twenty-eight analytes differed significantly between cMDD cases and controls (P depression. Changes were more prominent in cMDD, suggesting that molecular alterations in serum are associated with acute depression symptomatology. These findings may help to establish serum-based biomarkers of depression and could improve our understanding of its pathophysiology.

    Risperidone is an atypical antipsychotic commonly used for treatment of schizophrenia and other psychotic disorders. Although therapeutic drug monitoring is not routine for any of the atypical antipsychotics, serum antipsychotic concentrations are measured routinely to assess treatment nonadherence. In humans, risperidone is metabolized by cytochrome P450 2D6 to 9-hydroxyrisperidone; together these constitute the active moiety. Dose-proportional increases in serum concentrations have not been reported for the parent drug, but have been reported for 9-hydroxyrisperidone and the active moiety (i.e., the combined concentrations of risperidone and 9-hydroxyrisperidone). We describe a 34-year-old Caucasian man of Sicilian descent with a history of schizophrenia, disorganized type. He was suspected to be noncompliant with his risperidone therapy. Initially, active moiety risperidone concentrations increased linearly with prescribed dosage increases. However, with continued increases, active moiety concentrations adjusted downward and remained 17-36% below anticipated levels. We propose a method for estimating target active moiety concentrations of risperidone based on dosage-a method that may be used to guide clinicians in assessing nonadherence to risperidone treatment.

    Full Text Available Background/Aim. Hepcidin, an iron regulatory hormone, is increased in response to inflammation and some infections. We investigated the relationships among serum prohepcidin, iron status, Helicobacter pylori infection status, and the presence of gastric mucosal atrophy. Methods. Seventy subjects undergoing esophagogastroduodenoscopy underwent multiple gastric biopsies, and the possibility of H. pylori infection and the degree of endoscopic and histologic gastritis were investigated. In all subjects, serum prohepcidin and iron parameters were evaluated. Results. No correlations were observed between serum prohepcidin levels and the other markers of anemia, such as hemoglobin, serum iron, ferritin, and total iron binding capacity. Serum prohepcidin levels were not significantly different between the H. pylori-positive group and the H. pylori-negative group. Serum prohepcidin levels in atrophic gastritis patients were significantly lower than those in subjects without atrophic gastritis irrespective of H. pylori infection. Conclusion. Serum prohepcidin levels were not altered by H. pylori infection. Serum prohepcidin levels decrease in patients with atrophic gastritis, irrespective of H. pylori infection. It suggests that hepcidin may decrease due to gastric atrophy, a condition that causes a loss of hepcidin-producing parietal cells. Further investigations with a larger number of patients are necessary to substantiate this point.

    2015-10-01

    Full Text Available Human serum paraoxonase1 (PON1 is a calcium dependent es terase enzyme that hydrolyses lipid peroxides accumulating on low density lipoproteins. In the serum, PON1 enzyme is almost exclusively located on the high density lipoprotein (HDL. It hydrolyses oxidised lipids in low density lipoprotein (LDL and could therefore retard the development of atherosclerosis. As PON1 activity has a role in preventing atherosclerosis and coronary heart disease is common in Kerala, this study was conducted to assess the activity of the enzyme and its corelation to serum lipids. MATERIALS AND METHODS : In this case - control study, one hundred patients with coronary artery disease and one hundred healthy controls were included. Serum paraoxonase activity was meausured using phenyl acetate as substrate and lipid profile was done in a uto analyzer . RESULTS : The mean PON 1 activity {(70.21  27.62 in cases against (135.86  33.48 in controls (p value .000} was significantly low in CAD group compared to the control group. The CHD group had a significantly lower mean total cholesterol level (202.82  57.77 against 219.45  46.08 and lower mean HDL level (40.88  10.08 against 56.79  17.24. Correlation of the activity of PON1 with other variables for the combined group ( C ases and controls taken together showed that age is negatively correlated an d HDL is positively correlated with PON 1 activity. CONCLUSIONS : The activity of serum paraoxonase enzyme (PON1 is low in patients with coronary artery disease compared to healthy controls. Thus low serum PON1 enzyme activity is a risk factor for CAD. The activity of the serum PON1 enzyme increases with increase in HDL level and decreases with increase in age for the combined group.

    Despite recent technologic advances, total elbow arthroplasty has complication rates higher than that of total joint arthroplasty in other joints. With new antirheumatic treatments, the population receiving total elbow arthroplasty has shifted from patients with rheumatoid arthritis to those with posttraumatic arthritis, further compounding the high complication rate. The most common reasons for revision include infection, aseptic loosening, fracture, and component failure. Common mechanisms of total elbow arthroplasty failure include infection, aseptic loosening, fracture, component failure, and instability. Tension band fixation, allograft struts with cerclage wire, and/or plate and screw constructs can be used for fracture stabilization.

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

    Human adipose tissue is not only a storage organ but also an active endocrine organ to release adipokines. This study was conducted to investigate the relationship among serum taurine and adipokine levels, and body composition during 8-week human body weight control program in obese female college students. The program consisted of diet therapy, exercise, and behavior modification. After the program, body weight, body fat mass, percent body fat, and body mass index (BMI) were significantly decreased. Serum triglyceride (TG), total cholesterol (TC), and low-density lipoprotein cholesterol (LDL-C) levels were significantly decreased. Also serum adiponectin level was significantly increased and serum leptin level was significantly decreased. There were no differences in serum taurine and homocysteine levels. The change of serum adiponectin level was positively correlated with change of body fat mass and percent body fat. These results may suggest that body fat loss by human body weight control program is associated with an increase in serum adiponectin in obese female college students. Therefore, further study such as taurine intervention study is needed to know more exact correlation between dietary taurine intake and serum adipokines or body composition.

    Full Text Available Endocan is a newly recognized biomarker of sepsis. However, there have been no studies of the trends in endocan levels during infection and their associations with other clinical factors. The aim of this study was to assess the time course of endocan levels and the associations of endocan with clinical factors during infection by comparison with other biomarkers.Serum samples and blood cultures were obtained from patients who were diagnosed with infection from June 2013 to March 2014. Serum endocan, C-reactive protein (CRP, and procalcitonin (PCT levels during four periods during infection were measured (day 0, day 1-2, day 3-5, and day 6-10.A total of 78 patients were enrolled in this study. The median endocan level decreased by only 23% during infection, whereas both serum CRP and PCT levels decreased by more than 80%. Endocan levels were correlated to neither CRP levels nor PCT levels in each period. Endocan levels at day 0 in patients with bacteremia were higher than those without bacteremia (1.09 ng/mL vs 0.82 ng/mL, P=0.002, but neither CRP levels nor PCT levels at day 0 were different between the two groups. Areas under the receiver operator characteristic (ROC curves of endocan, CRP, and PCT at day 0 were 0.662, 0.343, and 0.563, respectively. Positive blood cultures tended to be related to high endocan levels, but not significantly (odds ratio: 4.24, 95% CI: 0.99-10.34, P=0.05.In bacteremic cases, serum endocan levels in bacteremia tended to be higher than in non-bacteremic cases. Although endocan level was not identified as a prognostic factor of bacteremia, further prospective study concerning the relationship between serum endocan level and bacteremia would be needed.

    Full Text Available BACKGROUND AND AIMS The purpose of this study was to determine the efficacy of red yeast rice (Monascus purpureus-fermented rice in lowering cholesterol in the blood. At the same time, alanine aminotranferase (ALT, aspartate aminotransferase (AST and gamma-glutamyl transferase (γ-GT were measured for notable side effects in the liver. Possible muscle damage was determined by measuring creatine kinase (CK. METHODS The cholesterol lowering effect in serum of red yeast rice-fed rats were studied over a 42-day feeding period. A total of 16 male Sprague-Dawley rats were randomised into 8 per group: control and treated. Treated rats were administered 1.35g/kg/day. Control rats were maintained on ordinary rat chow. RESULTS Serum cholesterol levels were significantly decreased by 19.13% in treated group compared to controls. This treatment also showed increase in serum ALT and AST activities by 41.90% and 21.53%, respectively. Mean CK activity in treated rats showed an increase by 32.32% when compared with control rats. γ-GT is the only enzyme that showed a decrease of 15.16% in sera of treated rats. Body weights of control and treated rats increased significantly by 10% end of feeding period but were not due to treatment. CONCLUSION Red yeast rice significantly decreased serum cholesterol level at a dosage of 1.35g/kg/day. However, the differences in serum enzyme activities between control and treated rats were not significant.

    Abstract Rationale: Laparoscopic total pancreatectomy is a complicated surgical procedure and rarely been reported. This study was conducted to investigate the safety and feasibility of laparoscopic total pancreatectomy. Patients and Methods: Three patients underwent laparoscopic total pancreatectomy between May 2014 and August 2015. We reviewed their general demographic data, perioperative details, and short-term outcomes. General morbidity was assessed using Clavien–Dindo classification and delayed gastric emptying (DGE) was evaluated by International Study Group of Pancreatic Surgery (ISGPS) definition. Diagnosis and Outcomes: The indications for laparoscopic total pancreatectomy were intraductal papillary mucinous neoplasm (IPMN) (n = 2) and pancreatic neuroendocrine tumor (PNET) (n = 1). All patients underwent laparoscopic pylorus and spleen-preserving total pancreatectomy, the mean operative time was 490 minutes (range 450–540 minutes), the mean estimated blood loss was 266 mL (range 100–400 minutes); 2 patients suffered from postoperative complication. All the patients recovered uneventfully with conservative treatment and discharged with a mean hospital stay 18 days (range 8–24 days). The short-term (from 108 to 600 days) follow up demonstrated 3 patients had normal and consistent glycated hemoglobin (HbA1c) level with acceptable quality of life. Lessons: Laparoscopic total pancreatectomy is feasible and safe in selected patients and pylorus and spleen preserving technique should be considered. Further prospective randomized studies are needed to obtain a comprehensive understanding the role of laparoscopic technique in total pancreatectomy. PMID:28099344

    This study sought to further evaluate the possible effects of serum calcium level on prostate cancer (PC) risk, with considering the age, body mass index (BMI), and sex steroid hormones. Using data from a prospective multicenter study, serum calcium concentration, as well as thorough demographic and medical characteristics, were determined in 194 cases with newly diagnosed, clinicopathologically confirmed PC and 317 controls, without any malignant disease, admitted to the same network of hospitals. Serum total and ionized calcium levels were categorized into tertiles. Multivariate logistic regression model was used to estimate odds ratios (OR) and corresponding 95% confidence intervals (CI) after adjustment for major potential confounders, including age, BMI, smoking, alcohol, education, occupation, marital status, family history of PC, and sex hormones level. The mean serum calcium level (±SD) in case and control groups was 9.22 (±0.46) mg/dl and 9.48 (±0.51) mg/dl, respectively (P < 0.001). After adjustment for mentioned confounders, a significant trend of decreasing risk was found for serum total calcium concentration (OR = 0.27, 95% CI = 0.12-0.59, comparing the highest with the lowest tertile) and ionized calcium (OR = 0.25, 95% CI = 0.10-0.58). An increase of 1 mg/dl in serum calcium level was associated with a significant decrease in PC risk (OR = 0.52; 95% CI = 0.34-0.76). Our findings reveal the inverse association between serum total and ionized concentrations and PC risk, which supports the hypothesis that calcium may protect against PC. Furthermore, no evidence was found regarding age, BMI, and sex steroid hormones to modify the association between serum calcium and PC risk.

  7. Estonian total ozone climatology

    Full Text Available The climatological characteristics of total ozone over Estonia based on the Total Ozone Mapping Spectrometer (TOMS data are discussed. The mean annual cycle during 1979–2000 for the site at 58.3° N and 26.5° E is compiled. The available ground-level data interpolated before TOMS, have been used for trend detection. During the last two decades, the quasi-biennial oscillation (QBO corrected systematic decrease of total ozone from February–April was 3 ± 2.6% per decade. Before 1980, a spring decrease was not detectable. No decreasing trend was found in either the late autumn ozone minimum or in the summer total ozone. The QBO related signal in the spring total ozone has an amplitude of ± 20 DU and phase lag of 20 months. Between 1987–1992, the lagged covariance between the Singapore wind and the studied total ozone was weak. The spring (April–May and summer (June–August total ozone have the best correlation (coefficient 0.7 in the yearly cycle. The correlation between the May and August total ozone is higher than the one between the other summer months. Seasonal power spectra of the total ozone variance show preferred periods with an over 95% significance level. Since 1986, during the winter/spring, the contribution period of 32 days prevails instead of the earlier dominating 26 days. The spectral densities of the periods from 4 days to 2 weeks exhibit high interannual variability.

    Prenatal exposure to polycyclic aromatic hydrocarbons (PAHs) is a high-priority public health concern. However, maternal to fetal transplacental transfer of PAHs has not been systematically studied. To investigate the transplacental transfer of PAHs from mother to fetus and determine the influence of lipophilicity (octanol-water partition coefficient, KOW) on transfer process, in the present study, we measured the concentrations of 15 PAHs in 95 paired maternal and umbilical cord serum, and placenta samples (in total 285 samples) collected in Shanghai, China. The average concentration of total PAHs was the highest in maternal serums (1290 ng g(-1) lipid), followed by umbilical cord serums (1150 ng g(-1) lipid). The value was the lowest in placenta samples (673 ng g(-1) lipid). Low molecular weight PAHs were the predominant compounds in the three matrices. Increases in fish and meat consumption did not lead to increases in maternal PAH levels, and no obvious gender differences in umbilical cord serums were observed. The widespread presence of PAHs in umbilical cord serums indicated the occurrence of transplacental transfer. The ratios of PAH concentrations in umbilical cord serum to those in maternal serum (F/M) and the concentrations in placenta to those in maternal serum (P/M) of paired samples were analyzed to characterize the transfer process of individual PAHs. Most F/M ratios on lipid basis were close to one (range: 0.79 to 1.36), which suggested that passive diffusion may control the transplacental transfer of PAHs from maternal serum to the fetal circulation. The P/M and F/M values calculated on lipid basis showed that PAHs with lower KOW were more likely to transfer from mother to fetus via the placenta. Copyright © 2016 Elsevier Ltd.

    Total lymphoid irradiation by itself can produce sufficient immunosuppression to prolong the survival of a variety of organ allografts in experimental animals. The degree of prolongation is dose-dependent and is limited by the toxicity that occurs with higher doses. Total lymphoid irradiation is more effective before transplantation than after, but when used after transplantation can be combined with pharmacologic immunosuppression to achieve a positive effect. In some animal models, total lymphoid irradiation induces an environment in which fully allogeneic bone marrow will engraft and induce permanent chimerism in the recipients who are then tolerant to organ allografts from the donor strain. If total lymphoid irradiation is ever to have clinical applicability on a large scale, it would seem that it would have to be under circumstances in which tolerance can be induced. However, in some animal models graft-versus-host disease occurs following bone marrow transplantation, and methods to obviate its occurrence probably will be needed if this approach is to be applied clinically. In recent years, patient and graft survival rates in renal allograft recipients treated with conventional immunosuppression have improved considerably, and thus the impetus to utilize total lymphoid irradiation for its immunosuppressive effect alone is less compelling. The future of total lymphoid irradiation probably lies in devising protocols in which maintenance immunosuppression can be eliminated, or nearly eliminated, altogether. Such protocols are effective in rodents. Whether they can be applied to clinical transplantation remains to be seen.

    Full Text Available Objective: To measure serum leptin and insulin levels in women with recurrent pregnancy loss using modified methods of High Performance Liquid Chromatography (HPLC, and to examine their influence on recurrent loss at different pregnancy trimesters.Methods: A case control study was conducted from, 1 September 2008 to 30 December 2009 in the Obstetric and Gynecological Department-Al-Khadimiya Teaching Hospital. HPLC technique with new modified method was used to estimate serum leptin and insulin hormones in samples of women with recurrent pregnancy loss (patients group, n=64 and healthy pregnant women at the end of the third gestational trimester as a control group (n=51.Results: Both serum leptin and insulin levels were high in women with pregnancy loss in their three trimesters. A significant correlation was found between age (r=0.535, p<0.018 and serum total leptin in women with RPL during the first trimester. Also, a highly significant correlation was found between serum total leptin and insulin in women with RPL during the first, second and third trimesters (r=0.894, r=0.931, and r =0.995 respectively. The number of women who lost their pregnancy during the first trimester was higher than those losing during other trimesters.Conclusion: It can be concluded that recurrent pregnancy loss in women at different trimester is associated with endocrine abnormalities where serum leptin and insulin levels increase in a different way compared with normal healthy pregnant women.

    Full Text Available The study aimed to determine if selenium deficiency, serum ceruloplasmin and traditional birth practices are risk factors for peripartum cardiomyopathy (PPCM, in Kano, Nigeria. This is a case-control study carried out in three hospitals, and PPCM patients were followed up for six months. Critically low serum selenium concentration was defined as <70 µg/L. A total of 39 PPCM patients and 50 controls were consecutively recruited after satisfying the inclusion criteria. Mean serum selenium in patients (61.7 ± 14.9 µg/L was significantly lower than in controls (118.4 ± 45.6 µg/L (p < 0.001. The prevalence of serum selenium <70 µg/L was significantly higher among patients (76.9% than controls (22.0% (p < 0.001. The mean ceruloplasmin and prevalence of socio-economic indices, multiparity, pregnancy-induced hypertension, obesity and twin pregnancy were not different between the groups (p > 0.05. Logistic regression showed that rural residency significantly increased the odds for serum selenium <70 µg/L by 2.773-fold (p = 0.037. Baseline serum levels of selenium and ceruloplasmin were not associated with six-month mortality. This study has shown that selenium deficiency is a risk factor for PPCM in Kano, Nigeria, and is related to rural residency. However, serum ceruloplasmin, customary birth practices and some other characteristics were not associated with PPCM in the study area.

    To study the impact of surgically verified endometriosis and serum and peritoneal fluid antiendometrial antibodies (AEA) on pregnancy outcomes in gamete intrafallopian transfer (GIFT), zygote intrafallopian transfer (ZIFT) and in vitro fertilization (IVF) patients using assisted reproductive technologies (ART). Surgical evaluation of endometriosis and collection of serum and peritoneal fluid was performed at the time of laparoscopy. For patients who did not undergo laparoscopy, only serum samples were obtained. Sera and peritoneal fluid were tested by indirect immunofluorescence for AEA. There was no correlation between surgically verified endometriosis, serum or peritoneal fluid AEA and clinical pregnancy in patients undergoing ART. There was no significant difference in surgically verified endometriosis in patients who delivered and those who miscarried (p < 0.0594), whereas serum (p < 0.0223) and peritoneal fluid (p < 0.0032) AEA showed differences. In the total group of 352 ART patients, positive serum AEA was statistically significant in those who miscarried vs. those who delivered (p < 0.0000). Endometriosis does not significantly impair the pregnancy potential of ART patients, but it may be associated with miscarriage. The presence of serum and peritoneal fluid AEA correlate better with miscarriage than surgically verified endometriosis.

    2008-08-11

    The total energy monitor (TE) is a thermal sensor that determines the total energy of each FEL pulse based on the temperature rise induced in a silicon wafer upon absorption of the FEL. The TE provides a destructive measurement of the FEL pulse energy in real-time on a pulse-by-pulse basis. As a thermal detector, the TE is expected to suffer least from ultra-fast non-linear effects and to be easy to calibrate. It will therefore primarily be used to cross-calibrate other detectors such as the Gas Detector or the Direct Imager during LCLS commissioning. This document describes the design of the TE and summarizes the considerations and calculations that have led to it. This document summarizes the physics behind the operation of the Total Energy Monitor at LCLS and derives associated engineering specifications.

  19. Algebraic totality, towards completeness

    Finiteness spaces constitute a categorical model of Linear Logic (LL) whose objects can be seen as linearly topologised spaces, (a class of topological vector spaces introduced by Lefschetz in 1942) and morphisms as continuous linear maps. First, we recall definitions of finiteness spaces and describe their basic properties deduced from the general theory of linearly topologised spaces. Then we give an interpretation of LL based on linear algebra. Second, thanks to separation properties, we can introduce an algebraic notion of totality candidate in the framework of linearly topologised spaces: a totality candidate is a closed affine subspace which does not contain 0. We show that finiteness spaces with totality candidates constitute a model of classical LL. Finally, we give a barycentric simply typed lambda-calculus, with booleans ${\\mathcal{B}}$ and a conditional operator, which can be interpreted in this model. We prove completeness at type ${\\mathcal{B}}^n\\to{\\mathcal{B}}$ for every n by an algebraic metho...

    Full Text Available Passive immunity transfer (PIT evaluation is an essential tool for the maintenance of healthy calves during the first months of life. Since lactation number and breed have been proven to influence immunoglobulin levels in colostrum, the aim of this study was to evaluate PIT from primiparous and multiparous Canchim cows to their calves. Blood samples were collected from the calves before colostrum intake and 1, 2, 7, 15 and 30 days thereafter, while colostrum samples from the cows were taken immediately after parturition. Activities of gamma-glutamyl transferase (GGT, alkaline phosphatase (ALP, and concentrations of total protein, albumin, globulins, immunoglobulin A (IgA, immunoglobulin G (IgG, total and ionized calcium, inorganic phosphorus, magnesium, sodium and potassium were evaluated in calves' serum and activities of GGT and ALP and concentrations of total protein, IgA and IgG were assessed in cow's colostrum whey. Immunoglobulins concentrations were evaluated by electrophoresis in polyacrylamide gels. Serum biochemistry evaluations revealed an increase in gamma-glutamyl transferase and alkaline phosphatase activities and in total protein, globulins, immunoglobulin A and immunoglobulin G levels in calves' serum after colostrum intake. Only total protein and light chain immunoglobulin G levels in colostrum whey were affected by the cows' lactation number. Phosphorus and magnesium levels in blood serum increased after colostrum intake, while sodium and potassium levels oscillated in the experimental period. PIT was influenced by the cows' lactation number but was efficient in both groups.

    Background Ferritin is associated with various cardiometabolic risk factors such as dyslipidemia, hypertension, obesity, and insulin resistance in adults. We aimed to study the association between serum ferritin levels and dyslipidemia in adolescents, because dyslipidemia is considered an important modifiable cardiovascular risk factor in the young. Methods We analyzed 1,879 subjects (1,026 boys and 853 girls) from the 2009–2010 Korean National Health and Nutrition Examination Survey IV. Subjects were categorized into quartiles according to their lipid parameters, which were classified according to age and gender. Those in the highest quartile groups for total cholesterol, low-density lipoprotein cholesterol (LDL-C), and triglyceride concentrations were diagnosed as having dyslipidemia. Those in the lowest quartile for high-density lipoprotein cholesterol (HDL-C) values were diagnosed with abnormal levels. Results In boys, total cholesterol, LDL-C, and triglyceride concentrations were significantly correlated with serum ferritin levels. In both boys and girls, serum ferritin levels were negatively associated with HDL-C values, even after adjusting for all covariates. Furthermore, there was no significant correlation between serum ferritin levels and total cholesterol, LDL, and triglyceride concentrations in girls. Conclusion Serum ferritin levels were significantly associated with major dyslipidemia parameters, more prominently in boys than in girls, and this association represents a cardiometabolic risk factor.

    Serum chemical values were determined in cold-stressed Holstein bull calves ranging from 1 to 7 days of age. The animals were anesthetized and cold-stressed until their core body temperature (colonic) was lowered 10 C. Animals were then rewarmed in warm water, with heat pads or heat lamps, or were allowed to recover naturally (unassisted) at room temperature. Blood samples were collected at selected intervals during cooling and recovery. Increases (P less than 0.05) were observed in the concentrations of glucose, calcium, phosphorus, iron, alkaline phosphatase, aspartate aminotransferase, lactate dehydrogenase, total protein, albumin, total globulin, serum urea nitrogen, uric acid, total bilirubin, indirect bilirubin, and cholesterol in the cold-stressed calves during cooling. Concentrations of chloride and insulin decreased (P less than 0.05) during the same period. Changes observed in many of the serum chemical values during rewarming were generally the reverse of the respective changes that occurred during cooling, although insulin values became exceedingly high in some cases midway or near the end of recovery. Serum enzyme values also remained high during most of recovery. Data did not indicate a clear advantage of one method of rewarming over the other methods used in terms of return of the serum chemical values to normal.

  10. Total hip arthroplasty

    Directory of Open Access Journals (Sweden)

    Slavković Nemanja

    2012-01-01

    Full Text Available Total hip arthroplasty is most common reconstructive hip procedure in adults. In this surgery we replace some parts of the upper femur and acetabulum with biocompatible materials. The main goal of this surgery is to eliminate pain and regain full extent of joint motion, maintaining hip stability. Surgical technique, biomaterials, design of the prosthesis and fixation techniques have evolved with time adjusting to each other. After total hip arthroplasty patients’ quality of life should be improved. There are many various postoperative complications. Some of them are fatal, and some are minor, which may become manifested years after surgery. Each next surgical procedure following previous hip surgery is associated with considerably lower chances to be successful. Therefore, in primary total hip arthroplasty, preoperative evaluation and preparation of patients are essential. Every orthopaedic surgeon needs to improve already adopted surgical skills applying them with precision and without compromise, with the main goal to achieve long-term durability of the selected implant. The number of total hip arthroplasties will also increase in future, and newer and higher quality materials will be used.

    Previous studies assessing the association between serum uric acid levels and neurological outcome after acute ischemic stroke reported conflicting results. A systematic review and meta-analysis were conducted to assess the impact of serum uric acid levels on outcome after acute ischemic stroke. Pubmed, Embase, Web of Science, and Google scholar were searched through September 26, 2014 to identify eligible published or unpublished studies on the association between serum uric acid levels and outcome after acute ischemic stroke. Hazard ratio (HR) for poor outcome or mean differences of serum uric acid levels with 95% confidence intervals (95% CIs) were pooled using meta-analysis. The primary outcome was occurrence of poor outcomes, while the secondary outcome was the mean differences of serum uric acid levels in patients with good or poor outcomes. Ten eligible studies with a total of 8131 acute ischemic stroke patients were included into the meta-analysis. Compared with low serum uric acid level, high serum uric acid level was associated better outcome after acute ischemic stroke (HR = 0.77, 95% CI 0.68-0.88, P = 0.0001). Sensitivity analysis further identified the prognostic role of serum uric acid levels on outcome after acute ischemic stroke. Patients with good outcomes had a higher serum uric acid level compared with those with poor outcome (mean difference = 30.61 μmol/L, 95% CI 20.13-41.08, P acute ischemic stroke. High uric acid level at the onset is a biomarker of better prognosis in patients with acute ischemic stroke.

    Tryptophan was measured in the ventricular CSE and serum and the neutral amino acids leucine, isoleucine, valine, phenylalanine, and tyrosine were measured in the serum of two cases with ventricular drains. Samples were taken every two hours for 24 hours in one case and for 16 hours in the other. The CSF tryptophan was correlated significantly with the free--that is, non-albumin-bound--serum tryptophan but not with the total serum tryptophan. CSF tryptophan was not correlated significantly with the ratio of free serum tryptophan to the sum of the neutral amino acids. These data suggest that, in man, brain tryptophan concentrations are influenced by the free and not the total serum tryptophan and that physiological variations of the neutral amino acids do not appreciably influence the concentration of brain trytophan.

    1998-08-01

    A decrease in serum albumin concentrations is an almost inevitable finding in disease states, and is primarily mediated in the acute phase by alterations in vascular permeability and redistribution. This change is not disease specific but marked changes that persist are generally associated with a poorer prognosis. Critical appraisal of long-standing practices and the availability of alternative colloid solutions have led to a reduction in albumin replacement therapy, and a widespread tolerance of lower albumin concentrations in patients. The factors determining serum albumin concentrations, their measurement and the implications of hypoalbuminaemia are reviewed. The clinical value of serum albumin measurement is discussed.

    Symptomatic adjacent segment degeneration of the cervical spine remains problematic for patients and surgeons alike. Despite advances in surgical techniques and instrumentation, the solution remains elusive. Spurred by the success of total joint arthroplasty in hips and knees, surgeons and industry have turned to motion preservation devices in the cervical spine. By preserving motion at the diseased level, the hope is that adjacent segment degeneration can be prevented. Multiple cervical disc...

    The aim of this study was to evaluate serum calprotectin levels and oxidative stress status in patients with papillary thyroid carcinoma (PTC) and the changes in their levels after total thyroidectomy. The study involved 30 patients with PTC and 30 healthy controls. Blood samples were obtained from the PTC patients before and 1 month after the operation. Preoperative and postoperative serum samples from PTC patients and healthy controls were analysed for calprotectin, total antioxidant status (TAS), total oxidant status (TOS) and lipid hydroperokside (LOOH). The preoperative calprotectin, TOS, OSI and LOOH levels of the patients with PTC were significantly higher compared to those of the control group (p calprotectin decreased significantly in patients with PTC after the operation (p calprotectin levels were positively correlated with TOS, OSI and LOOH levels and negatively correlated with TAS levels in patients with PTC. In conclusion, serum calprotectin levels is increased in patients with PTC, and calprotectin is positively correlated with TOS and LOOH. Serum calprotectin levels is significantly decreased after total thyroidectomy.

    A total of twenty-four Yorkshire gilt pigs of 6-7 weeks of age were used in a 2×2 factorial experiment to determine the individual and combined effects of the inclusion of two dietary factors (cholesterol rich, 3% β-cyclodextrin (BCD) and Lactobacillus acidophilus cultures) on total cholesterol and LDL-cholesterol levels in blood serum. Pigs were assigned randomly to treatment groups (n 6). Total serum cholesterol concentrations decreased after 3 weeks in all the experimental treatment groups, including diets with BCD, L. acidophilus or both. Similar trends were observed for serum LDL-cholesterol concentrations among the experimental treatments. No statistically significant differences from the control group were observed in either total serum cholesterol or LDL-cholesterol concentrations (Pacidophilus. However, significant differences in total serum cholesterol concentrations were observed when comparing the combined treatment group (BCD and L. acidophilus) with the control group, which consisted of a basal diet and sterile milk. The combined treatment group exhibited 17·9% lower total serum cholesterol concentration after 3 weeks. Similar significant differences were observed when comparing the combined effect experimental group with the control group after 3 weeks. The combined treatment group exhibited 27·9% lower serum LDL-cholesterol concentrations.

    Hypocalcemia is a well-known complication of total thyroidectomy. Patients who have previously undergone gastric bypass surgery may be at increased risk of hypocalcemia due to gastrointestinal malabsorption, secondary hyperparathyroidism, and an underlying vitamin D deficiency. We present the case of a 58-year-old woman who underwent a total thyroidectomy for the follicular variant of papillary thyroid carcinoma. Her history included Roux-en-Y gastric bypass surgery. Following the thyroid surgery, she developed postoperative hypocalcemia that required large doses of oral calcium carbonate (7.5 g/day), oral calcitriol (up to 4 μg/day), intravenous calcium gluconate (2.0 g/day), calcium citrate (2.0 g/day), and ergocalciferol (50,000 IU/day). Her serum calcium levels remained normal on this regimen after hospital discharge despite persistent hypoparathyroidism. Bariatric surgery patients who undergo thyroid surgery require aggressive supplementation to maintain normal serum calcium levels. Preoperative supplementation with calcium and vitamin D is strongly recommended.

    Hepatoblastoma (HB) is the most common primary liver cancer in children. The conventional serum marker for HB, alpha-fetoprotein (AFP), has its limitations. Novel serum markers need to be explored. Glypican 3 (GPC3) has been reported to be an excellent histological immunomarker for HB. However, the clinical value of serum GPC3 in patients with HB is unknown. A total of 184 serum samples were tested for both GPC3 by ELISA, and AFP by immunometric assay. Of these, 134 were from 32 patients with HB at three treatment stages, 30 from age-matched patients with benign hepatobiliary disorders (BHD) and 20 from age-matched “normal controls”(NC). We found that the GPC3 levels in HB pretreatment group were significantly higher than those in NC group and HB remission group but not statistically different from those in BHD group and HB during treatment group. In contrast, AFP showed significant differences among different groups. The areas under the receiver operating curve (AUROC) value, sensitivity and specificity of GPC3 for HB pretreatment group versus all controls were all significantly lower than those of AFP. Serum GPC3 levels were not associated with prognostic parameters. We concluded that GPC3 is inferior to AFP as a serum marker for HB. PMID:28378832

    Haptoglobin (Hp) is a glycoprotein involved in the acute phase response to inflammation. Our previous findings indicate that Hp mRNA and protein are present in the adipose tissue of rodents and that Hp gene expression is up-regulated in obese models. The aim of the present study was to establish whether Hp could be considered a marker of obesity in humans. In 312 subjects, serum Hp was correlated directly with body mass index (BMI), leptin, C-reactive protein (CRP), and age. In a multivariate stepwise regression analysis, BMI and CRP were independent determinants of serum Hp in females, with BMI having the strongest effect. CRP and age were independent determinants of serum Hp in males, although explaining only a modest percentage of the total variability. Serum Hp was positively associated with body fat, as assessed by dual-energy x-ray absorptiometry, both in female and in male groups. The level of significance improved when serum Hp was analyzed against fat mass adjusted for lean mass. Finally, Northern and Western blot analyses performed in biopsies of sc abdominal fat from 20 obese individuals showed the presence of Hp mRNA and protein in the human adipose tissue. In conclusion, serum Hp constitutes a novel marker of adiposity in humans, and the adipose tissue likely contributes to determine its levels.

    High serum copper concentration--a well-known effect of oral contraceptive (OC) use--has been linked to increased mortality from cardiovascular disease. The influence of OCs containing newer progestins has not been investigated, however. This concern was addressed in a 1987-88 cross-sectional epidemiologic study of 610 nonpregnant, nonlactating West German women 18-44 years of age. 195 women (32.1%) were current OC users, but only 152 of these women were able to cite the name of the formulation they were taking. In 70% of cases, the OC contained less than 45 mcg of ethylestradiol (median dose, 32.4 mcg). The most common progestin components were desogestrel (41%) and levonorgestrel (30%). Mean serum copper concentration was higher among users of all types of OCs than among non-users, but this concentration varied more strongly according to the OC's progestin compound than its estrogen content. The greatest increase in serum copper (55% compared with non-users) was recorded in users of OCs containing anti-androgen progestins, followed by desogestrel (46%), norethisterone/lynestrenol (42%), and levonorgestrel (34%). The increase in serum copper was more pronounced in women taking OCs containing 45 mcg or less of ethylestradiol than in users of OCs with a high estrogen dose. In the regression models, the different progestin compounds alone explained 28% of the total variance in serum copper concentration. Further investigation of OC-induced increases in serum copper concentration and their impact on cardiovascular risk are warranted.

    Serum corticosteroid levels are routinely measured as markers of stress in wild animals. However, corticosteroid levels rise rapidly in response to the acute stress of capture and restraint for sampling, limiting its use as an indicator of chronic stress. We hypothesized that serum corticosteroid binding globulin (CBG), the primary transport protein for corticosteroids in circulation, may be a better marker of the stress status prior to capture in grizzly bears (Ursus arctos). To test this, a full-length CBG cDNA was cloned and sequenced from grizzly bear testis and polyclonal antibodies were generated for detection of this protein in bear sera. The deduced nucleotide and protein sequences were 1218 bp and 405 amino acids, respectively. Multiple sequence alignments showed that grizzly bear CBG (gbCBG) was 90% and 83% identical to the dog CBG nucleotide and amino acid sequences, respectively. The affinity purified rabbit gbCBG antiserum detected grizzly bear but not human CBG. There were no sex differences in serum total cortisol concentration, while CBG expression was significantly higher in adult females compared to males. Serum cortisol levels were significantly higher in bears captured by leg-hold snare compared to those captured by remote drug delivery from helicopter. However, serum CBG expression between these two groups did not differ significantly. Overall, serum CBG levels may be a better marker of chronic stress, especially because this protein is not modulated by the stress of capture and restraint in grizzly bears.

    Ankle arthritis results in a stiff and painful ankle and can be a major cause of disability. For people with end-stage ankle arthritis, arthrodesis (ankle fusion) is effective at reducing pain in the shorter term, but results in a fixed joint, and over time the loss of mobility places stress on other joints in the foot that may lead to arthritis, pain and dysfunction. Another option is to perform a total ankle joint replacement, with the aim of giving the patient a mobile and pain-free ankle. In this article we review the efficacy of this procedure, including how it compares to ankle arthrodesis, and consider the indications and complications.

    1998-01-01

    As the most abundant protein in the circulatory system albumin contributes 80% to colloid osmotic blood pressure. Albumin is also chiefly responsible for the maintenance of blood pH. It is located in every tissue and bodily secretion, with extracellular protein comprising 60% of total albumin. Perhaps the most outstanding property of albumin is its ability to bind reversibly to an incredible variety of ligands. It is widely accepted in the pharmaceutical industry that the overall distribution, metabolism, and efficiency of many drugs are rendered ineffective because of their unusually high affinity for this abundant protein. An understanding of the chemistry of the various classes of pharmaceutical interactions with albumin can suggest new approaches to drug therapy and design.

    This meta-analysis aims to comprehensively evaluate the association between total homocysteine (tHcy) levels, serum folic acid, vitamin B12, vitamin B6 levels, methylenetetrahydrofolate reductase (MTHFR) C677T genotype, and risk of normal-tension glaucoma (NTG). A systematic search of the EMBASE and PubMed databases was performed to evaluate plasma tHcy levels, serum folic acid, B vitamins' mean difference, and odds ratios of MTHFR C677T genotype between cases and controls. A total of 7 studies including 458 cases and 555 controls meeting the inclusion criteria were involved in this meta-analysis. There were 4 studies for tHcy (149 cases and 148 controls), 2 studies for vitamin B6, vitamin B12, and folate (90 cases and 82 controls), and 4 studies for MTHFR (343 cases and 449 controls). Overall, the mean plasma tHcy levels, serum folic acids, vitamin B12, and vitamin B6 levels were 1.16 μmol/L [95% confidence interval (CI), -0.13, 2.45], -0.62 μmol/L (95% CI, -1.98, 0.74), 5.81 μmol/L (95% CI, -3.53, 15.14), and -16.79 μmol/L (95% CI, -86.09, 52.51). MTHFR TT genotype was found to be unrelated to NTG risk (odds ratio=1.08; 95% CI, 0.69, 1.69). NTG is not associated with elevated plasma tHcy, serum folic acid, serum vitamin B12, serum vitamin B6, and MTHFR C677T genotype.

    The development and testing of a breadboard version of a highly sensitive total-organic-carbon (TOC) analyzer are reported. Attention is given to the system components including the CO2 sensor, oxidation reactor, acidification module, and the sample-inlet system. Research is reported for an experimental reagentless oxidation reactor, and good results are reported for linearity, sensitivity, and selectivity in the CO2 sensor. The TOC analyzer is developed with gravity-independent components and is designed for minimal additions of chemical reagents. The reagentless oxidation reactor is based on electrolysis and UV photolysis and is shown to be potentially useful. The stability of the breadboard instrument is shown to be good on a day-to-day basis, and the analyzer is capable of 5 sample analyses per day for a period of about 80 days. The instrument can provide accurate TOC and TIC measurements over a concentration range of 20 ppb to 50 ppm C.

    Full Text Available BACKGROUND Diabetes Mellitus is not a disease, but can be considered as a metabolic syndrome in which not only the sugar metabolism is impaired, but also is said to have profound effects or influence on other metabolic disorders. Almost, all the metabolic pathways will be affected in this dreadful disease. It’s a slow poison, which starts showing its effects as the time progresses. One of the commonest complaint seen in the diabetes patients is the loss of libido or derangement in the sexual physiology. The most common complaints include the erectile dysfunction and mood elevations. The patients also complain of stressfulness. These symptoms point out towards a common source i.e. decrease in the testosterone levels. A sincere effort has been put in this study to understand the relations of total serum testosterone seen in diabetes mellitus patients. This may help the physicians, operating surgeons, and also anaesthetists to understand the plethora of metabolic disturbances seen in the diabetes mellitus and take necessary steps to correct such conditions and also take necessary preventive members that may result in catastrophe. METHODS This study is a cross-sectional study done in Government Medical College, Nizamabad. One hundred known diabetic patients who attended the Department of Surgery, Government Medical College, Nizamabad, were identified. The fasting levels of postprandial level and HbA1c were detected. The total testosterone level was identified. The incidence of low testosterone (<300 ng/dL was checked. The different levels of glucose (Fasting, postprandial and HbA1c was compared to the amount of serum total testosterone. Finally, the time since the diabetes was known to the patients were correlated to the levels of testosterone. RESULT In the present study, the incidence of the low total testosterone was found to be in 39 percent of the diabetics. In the present study, there is a positive correlation between the total testosterone

Receiver operating characteristic (ROC curves were used to evaluate the validity of serum proteins for discriminating between asthma clusters.Results: Classification of asthma patients identified one cluster with high ECP serum levels, increased blood eosinophils, low FEV1 values, and good FEV1 improvement in response to asthma therapy (n=60 and one cluster with low ECP serum levels, low numbers of blood eosinophils, higher FEV1 values, and no FEV1 improvement in response to asthma therapy (n=131. Serum interleukin (IL-8, eotaxin, vascular endothelial growth factor (VEGF, cutaneous T-cell-attracting chemokine (CTACK, growth-related oncogene (GRO-α, and hepatocyte growth factor (HGF were significantly different between the two clusters of asthma patients. ROC analysis for serum proteins calculated a sensitivity of 55.9% and specificity of 75.8% for discriminating between them.Conclusion: Serum cytokine and chemokine levels might be

    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.

    Full Text Available MicroRNAs (miRNAs are small noncoding RNAs that act as regulators of gene expression by targeting mature messenger RNAs. Following the initial report of the presence of miRNAs in serum and plasma a number of studies have successfully demonstrated the use of these miRNAs as biomarkers of disease. Currently, there are many methods of isolating total RNA from liquid samples. Here, we describe a simple, cost effective method for extraction of RNA from human serum as well as subsequent real time PCR analysis of miRNA levels.

    Full Text Available Background: Primary total elbow arthroplasty (TEA is a challenging procedure for orthopedic surgeons. It is not performed as frequently as compared to hip or knee arthroplasty. The elbow is a nonweight-bearing joint; however, static loading can create forces up to three times the body weight and dynamic loading up to six times. For elderly patients with deformity and ankylosis of the elbow due to posttraumatic arthritis or rheumatoid arthritis or comminuted fracture distal humerus, arthroplasty is one of the option. The aim of this study is to analyze the role of primary total elbow arthroplasty in cases of crippling deformity of elbow. Materials and Methods: We analyzed 11 cases of TEA, between December 2002 and September 2012. There were 8 females and 3 males. The average age was 40 years (range 30-69 years. The indications for TEA were rheumatoid arthritis, comminuted fracture distal humerus with intraarticular extension, and posttraumatic bony ankylosis of elbow joint. The Baksi sloppy (semi constrained hinge elbow prosthesis was used. Clinico-radiological followup was done at 1 month, 3 months, 6 months, 1 year, and then yearly basis. Results: In the present study, average supination was 70° (range 60-80° and average pronation was 70° (range 60-80°. Average flexion was 135° (range 130-135°. However, in 5 cases, there was loss of 15 to 35° (average 25° of extension (45° out of 11 cases. The mean Mayo elbow performance score was 95.4 points (range 70-100. Arm length discrepancy was only in four patients which was 36% out of 11 cases. Clinico-radiologically all the elbows were stable except in one case and no immediate postoperative complication was noted. Radiolucency or loosening of ulnar stem was seen in 2 cases (18% out of 11 cases, in 1 case it was noted after 5 years and in another after 10 years. In second case, revision arthroplasty was done, in which only ulnar hinge section, hinge screw and lock screw with hexagonal head

    Adipocytokines are thought to be associated with inflammatory disorders and autoimmune diseases. However, limited information is available on the relationship between serum adipocytokine levels, Graves' disease (GD), and Graves' ophthalmopathy (GO). The present study examined the relationship between serum adipocytokine levels and GD and GO. A total of 80 patients with GD participated in this study. The medical records of patients were reviewed retrospectively. GO activity was assessed using the clinical activity score (CAS). GO severity was assessed by the modified NOSPECS classification and included soft tissue involvement, proptosis, and extraocular muscle involvement. Serum adiponectin, leptin, resistin, and retinol-binding protein 4 (RBP-4) levels were measured using commercially available enzyme-linked immunosorbent assays. The prevalence of GO was 36.3%. Serum adiponectin, leptin, and resistin levels were significantly higher in patients with GO than in those without GO. The CAS was positively correlated with serum adiponectin and leptin levels. The total eye score was positively correlated with serum adiponectin, leptin, resistin, and RBP-4 levels. A multivariate analysis revealed that serum leptin and resistin levels were associated with the presence of GO after adjusting for clinical factors. Free thyroxine was negatively correlated with serum leptin level. These results suggest that adipocytokines, such as leptin and resistin, may play a role in inflammatory and autoimmune processes of GD and GO. Future studies with larger numbers of patients are required to establish relationships between serum adipocytokines levels and GO and ascertain the role of adipocytokines in GD and GO.

    Full Text Available Abstract Background Selenium is an essential micronutrient known for its antioxidant function. However, the association of serum selenium with lipid profiles and fasting glucose are inconsistent in populations with average intake of selenium. Furthermore, there were few studies conducted specifically for the elderly. This study examined the relationship of serum selenium concentration with serum lipids and fasting glucose in the Taiwanese elderly population. Methods This was a cross-sectional study of 200 males and females aged 65-85 years (mean 71.5 ± 4.6 years from Taipei, Taiwan. Serum selenium was measured by inductively coupled plasma-mass spectrometer. The association between serum selenium and metabolic factors was examined using a multivariate linear regression analysis after controlling several confounders. Results The mean serum selenium concentration was 1.14 μmol/L, without significant difference between sexes. Total cholesterol, triglycerides, and LDL cholesterol increased significantly with serum selenium concentration (P P P P Conclusions Total cholesterol, triglycerides, and LDL cholesterol, and fasting serum glucose concentrations increased significantly with serum selenium concentration in the Taiwanese elderly. The underlying mechanism warrants further research.

    Ten patients with lupus nephritis and marked proteinuria (3.9 g or more/d) that did not respond adequately to treatment with prednisone alone or prednisone in combination with azathioprine were treated with total lymphoid irradiation in an uncontrolled feasibility study. Within 6 weeks after the start of total lymphoid irradiation, the serum albumin level rose in all patients in association with a reduction in the serum level of anti-DNA antibodies, an increase in the serum complement level, or both. Improvement in these variables persisted in eight patients followed for more than 1 year, with the stabilization or reduction of the serum creatinine level. Urinary leakage of albumin was substantially reduced in all patients. Side effects associated with radiotherapy included transient constitutional complaints in ten patients, transient blood element depressions in three, localized viral and bacterial infections in four, and ovarian failure in one. The results suggest that total lymphoid irradiation may provide an alternative to cytotoxic drugs in the treatment of lupus nephritis.

    The total artificial heart (TAH) is a form of mechanical circulatory support in which the patient's native ventricles and valves are explanted and replaced by a pneumatically powered artificial heart. Currently, the TAH is approved for use in end-stage biventricular heart failure as a bridge to heart transplantation. However, with an increasing global burden of cardiovascular disease and congestive heart failure, the number of patients with end-stage heart failure awaiting heart transplantation now far exceeds the number of available hearts. As a result, the use of mechanical circulatory support, including the TAH and left ventricular assist device (LVAD), is growing exponentially. The LVAD is already widely used as destination therapy, and destination therapy for the TAH is under investigation. While most patients requiring mechanical circulatory support are effectively treated with LVADs, there is a subset of patients with concurrent right ventricular failure or major structural barriers to LVAD placement in whom TAH may be more appropriate. The history, indications, surgical implantation, post device management, outcomes, complications, and future direction of the TAH are discussed in this review.

    Total disc replacement (TDR) (partial disc replacement will not be described) has been used in the lumbar spine since the 1980s, and more recently in the cervical spine. Although the biomechanical concepts are the same and both are inserted through an anterior approach, lumbar TDR is conventionally indicated for chronic low back pain, whereas cervical TDR is used for soft discal hernia resulting in cervicobrachial neuralgia. The insertion technique must be rigorous, with precise centering in the disc space, taking account of vascular anatomy, which is more complex in the lumbar region, particularly proximally to L5-S1. All of the numerous studies, including prospective randomized comparative trials, have demonstrated non-inferiority to fusion, or even short-term superiority regarding speed of improvement. The main implant-related complication is bridging heterotopic ossification with resulting loss of range of motion and increased rates of adjacent segment degeneration, although with an incidence lower than after arthrodesis. A sufficiently long follow-up, which has not yet been reached, will be necessary to establish definitively an advantage for TDR, particularly in the cervical spine.

    Abstract Despite the well-documented role of calcium in cell metabolism, its role in the development of cardiovascular disease is still under heavy debate. Several studies suggest that calcium supplementation might be associated with an increased risk of coronary heart disease, whereas others underline a significant effect on lowering high blood pressure and hyperlipidemia. The purpose of this study was to investigate, in a large nonselected cohort from South Italy, if serum calcium levels correlate with lipid values and can therefore be linked to higher individual cardiovascular risk. Eight-thousand-six-hundred-ten outpatients addressed to the Laboratory of Clinical Biochemistry, University of Magna Græcia, Catanzaro, Italy from January 2012 to December 2013 for routine blood tests, were enrolled in the study. Total HDL-, LDL- and non-HDL colesterol, triglycerides, and calcium were determined with standard methods. We observed a significant association between total cholesterol, LDL-cholesterol, HDL-cholesterol, non-HDL cholesterol, triglycerides, and serum calcium in men and postmenopause women. Interestingly, in premenopause women, we only found a direct correlation between serum calcium, total cholesterol, and HDL-cholesterol. Calcium significantly increased while increasing total cholesterol and triglycerides in men and postmenopause women. Our results confirm that progressive increase of serum calcium level correlates with worsening of lipid profile in our study population. Therefore, we suggest that a greater caution should be used in calcium supplement prescription particularly in men and women undergoing menopause, in which an increase of serum lipids is already known to be associated with a higher cardiovascular risk.

    Guangwei Du

    Full Text Available BACKGROUND: The occurrence of Parkinson's disease (PD is known to be associated both with increased nigrostriatal iron content and with low serum cholesterol and PD, but there has been no study to determine a potential relationship between these two factors. METHODS: High-resolution MRI (T1-, T2, and multiple echo T2*-weighted imaging and fasting lipid levels were obtained from 40 patients with PD and 29 healthy controls. Iron content was estimated from mean R2* values (R2* = 1/T2* calculated for each nigrostriatal structure including substantia nigra, caudate, putamen, and globus pallidus. This was correlated with serum cholesterol levels after controlling for age, gender, and statin use. RESULTS: In patients with PD, higher serum cholesterol levels were associated with lower iron content in the substantia nigra (R = -0.43, p = 0.011 for total-cholesterol, R = -0.31, p = 0.080 for low-density lipoprotein and globus pallidus (R = -0.38, p = 0.028 for total-cholesterol, R = -0.27, p = 0.127 for low-density lipoprotein, but only a trend toward significant association of higher total-cholesterol with lower iron content in the striatum (R = -0.34, p = 0.052 for caudate; R = -0.32, p = 0.061 for putamen. After adjusting for clinical measures, the cholesterol-iron relationships held or became even stronger in the substantia nigra and globus pallidus, but weaker in the caudate and putamen. There was no significant association between serum cholesterol levels and nigrostriatal iron content for controls. CONCLUSIONS: The data show that higher serum total-cholesterol concentration is associated with lower iron content in substantia nigra and globus pallidus in Parkinson's disease patients. Further studies should investigate whether this is mechanistic or epiphenomenological relationship.

    A clinical blood serum mercury test of 111 dentists and auxiliaries revelaed that more than 50% had above normal serum mercury levels. This study showed that there may be a mercury health hazard in some dental environments. Acute mercury poisoning may be corrected simply by removing the cause, but long-term chronic effects are not known. Frequent screening of offices and personnel is advised. Experience reported here indicates that large amounts of mercury vapor are emitted when an amalgam carrier is heated over a flame ot dislodge particles, and also, that water-covered amalgam scrap relesases mercury vapor.

    We examined the epidemiological associations between serum fructosamine and dyslipidemia indices in community-dwelling adults. Clinical characteristics and lipid profiles were analyzed in 1352 community-dwelling adults. The demographic characteristics and laboratory results were grouped according to the quartiles of serum fructosamine concentrations in all eligible individuals. From the bottom to the top quartile of serum fructosamine, there were graded increases in age, total cholesterol (TC), fasting blood glucose (FBG), total protein (TP), triglyceride (TG), total cholesterol/ high density lipoprotein-cholesterol (TC/HDL-C) and atherogenic index of plasma (AIP). Serum fructosamine was positive correlated with age, TC, FBG, TP, TG, TC/HDL-C and AIP in whole individuals. The positive correlations were then observed in both genders between serum fructosamine and TC, FBG, TP, TG. Two dominant factors were identified by principal component analysis. Logistic regression analysis showed that the two factors were associated with increased serum fructosamine with adjustment for gender, age, body mass index (BMI), FBG and TP. The similar results were observed in males, but not in females. Dyslipidemia tends to contribute to increased serum fructosamine concentrations in study population, suggesting that elevated serum fructosamine may herald an increased risk of cardiovascular disease among community-dwelling adults, especially in males.

    Interleukin-13 (IL-13) is an immunosuppressive cytokine produced by several immune cells and cancer cells. The aim of this retrospective study was to determine if serum IL-13 levels have an association with clinical outcome in patients with colorectal cancer. A total of 241 patients with colorectal cancer were enrolled in the present study. Preoperative serum IL-13 concentrations were measured by enzyme-linked immunosorbent assay. We analyzed the association of serum IL-13 levels with clinicopathological variables. Patients with lymph node metastasis, lymphatic invasion, vascular invasion, distant metastases or advanced stage of disease had significantly lower serum IL-13 levels. Low serum IL-13 was significantly associated with both poor recurrence-free and overall survival. Multivariate analysis showed that low IL-13 levels were an independent predictive marker for poor prognosis. In conclusion, our data suggest that low serum IL-13 levels may be a useful predictive marker for poor prognosis in colorectal cancer.

    The blood serum of the reindeer does not virtually contain any antibodies to respiratory and intestinal viruses widely spread among the cattle. The reindeer blood serum is comparable with the bovine serum by the contents of chlorides, hemoglobin, total protein and protein fractions; however, it is different from the latter by a 2.5-fold higher content of glucose and by a higher osmotic pressure. The serum stimulates the mitotic cell activity and cell monolayer production; it also contributes to accumulating the cytopathogenic viruses in cell culture. 5- and 10%-serum, when added to a nutrient medium, ensures the reproduction of bovine leucosis virus and the accumulation of the antigen of this virus in a continuous cell culture that is chronically infected with the virus. Finally, the reindeer serum stabilizes the viability of ovocytes and stimulates the bovine embryo development at transplantation.

    Severe hyperkalemia (serum potassium level >6 mmol per liter [mEq per liter]), often with electrocardiographic disturbances, was noted at presentation in 30% of 73 hyperglycemic episodes (serum glucose concentration >25 mmol per liter [455 mg per dl]) observed in 15 in-hospital patients with insulin-dependent diabetes mellitus who were receiving long-term hemodialysis or peritoneal dialysis. Serum glucose concentration and total carbon dioxide content correlated significantly with the presenting serum potassium concentration. Treatment with parenteral insulin alone resulted in a decrease of the serum glucose value from 41 +/- 14 (standard deviation) to 11 +/- 5 mmol per liter (P decrease in potassium concentration during treatment. Insulin alone resulted in correction of hyperkalemia in all instances. Posttreatment hypokalemia was noted in only two instances, each associated with both ketoacidosis and low-normal serum potassium concentration at hyperglycemia. Giving insulin is the only treatment usually needed for the hyperkalemia of hyperglycemia in patients on ongoing dialysis.

    The effects of pregnant mare serum gonadotrophin (PMSG) dose and PMSG antiserum on superovulation in crossbred beef cows were studied. In experiment I, three groups were treated with 1200, 2400 or 3600 IU of PMSG and 48 h later with prostaglandin (PGF). The mean numbers of corpora lutea (CL), unovulated follicles, and total ova/embryos collected increased as the PMSG dose increased. The percent of fertilized ova and transferable embryos was lowest in the highest dose group (p superovulation of beef cows with PMSG and treatment with PMSG antiserum will induce a higher superovulatory response and will result in higher CL numbers and fewer unovulated follicles. Further, the variability in the superovulatory response to PMSG treatment was still evident when PMSG antiserum was administered. PMID:8055430

    Although hypocupremia is a well-known consequence of long-term total parenteral nutrition (TPN), its incidence as well as the duration of TPN necessary to induce it are still unsettled. The purpose of this study is to review the changes in serum copper level in 25 patients receiving TPN for a period longer than 2 wk (mean duration 6 wk) at the Istituto Nazionale Tumori of Milan and to evaluate the possible relationship of cupremia with the basic disease. Main indications for TPN included enterocutaneous fistulas (11 patients), cancer cachexia (10 patients), radiation enteropathy (two patients), and severe postoperative stricture following esophagogastric resection (two patients). Mean value of serum copper at the beginning of the study was 143 micrograms/100 ml (normal value 65-165 micrograms/100 ml), and the regression analysis showed a mean fall of 5.64 micrograms/100 ml/wk. Hypocupremia occurred in four patients (three with intestinal fistulas and one with radiation obstructive enteritis) at 5th, 6th, 9th, and 6th wk of TPN, respectively. No patient with cancer cachexia developed hypocupremia. No patient with hypocupremia had clinical evidence of a copper deficiency syndrome. We conclude that 1) hypocupremia does not occur within the first month of TPN; 2) its incidence is about 16% in patients intravenously fed for period longer than 2 wk; 3) it is more frequent in patients with enterocutaneous fistulas, whereas it never occurs in patients with cancer cachexia, and 4) it is not necessarily associated to a clinicometabolic syndrome of copper deficiency. Finally, the "nutritional" meaning of serum copper should be questioned in cancer patients since it could represent a "tumor marker."

    Objective:Hepatocellular carcinoma (HCC) is a leading cause of cancer-related deaths. Novel serum biomarkers are required to increase the sensitivity and specificity of serum screening for early HCC diagnosis. This study employed a quantitative proteomic strategy to analyze the differential expression of serum glycoproteins between HCC and normal control serum samples. Methods:Lectin affnity chromatography (LAC) was used to enrich glycoproteins from the serum samples. Quantitative mass spectrometric analysis combined with stable isotope dimethyl labeling and 2D liquid chromatography (LC) separations were performed to examine the differential levels of the detected proteins between HCC and control serum samples. Western blot was used to analyze the differential expression levels of the three serum proteins. Results:A total of 2,280 protein groups were identiifed in the serum samples from HCC patients by using the 2D LC-MS/MS method. Up to 36 proteins were up-regulated in the HCC serum, whereas 19 proteins were down-regulated. Three differential glycoproteins, namely, fibrinogen gamma chain (FGG), FOS-like antigen 2 (FOSL2), and α-1, 6-mannosylglycoprotein 6-β-N-acetylglucosaminyltransferase B (MGAT5B) were validated by Western blot. All these three proteins were up-regulated in the HCC serum samples. Conclusion:A quantitative glycoproteomic method was established and proven useful to determine potential novel biomarkers for HCC.

    Objective Hepatocellular carcinoma (HCC) is a leading cause of cancer-related deaths. Novel serum biomarkers are required to increase the sensitivity and specificity of serum screening for early HCC diagnosis. This study employed a quantitative proteomic strategy to analyze the differential expression of serum glycoproteins between HCC and normal control serum samples. Methods Lectin affinity chromatography (LAC) was used to enrich glycoproteins from the serum samples. Quantitative mass spectrometric analysis combined with stable isotope dimethyl labeling and 2D liquid chromatography (LC) separations were performed to examine the differential levels of the detected proteins between HCC and control serum samples. Western blot was used to analyze the differential expression levels of the three serum proteins. Results A total of 2,280 protein groups were identified in the serum samples from HCC patients by using the 2D LC-MS/MS method. Up to 36 proteins were up-regulated in the HCC serum, whereas 19 proteins were down-regulated. Three differential glycoproteins, namely, fibrinogen gamma chain (FGG), FOS-like antigen 2 (FOSL2), and α-1,6-mannosylglycoprotein 6-β-N-acetylglucosaminyltransferase B (MGAT5B) were validated by Western blot. All these three proteins were up-regulated in the HCC serum samples. Conclusion A quantitative glycoproteomic method was established and proven useful to determine potential novel biomarkers for HCC.

    Refractometric analysis is very rapid, accurate and simple method of analysis measuring refractive index of biological liquids such as serum, plasma, spinal fluid, urine. This method can be used for definition total protein and solids concentrations in serum. The value of refractive index depends on all substances in serum including proteins, lipids as well as low molecular weight compounds, for example ions of different metals. Refractometric analysis shows strong correlations between protein concentrations in serum of patients with multiple myeloma and its(serum) refractive index which depends on protein concentration and doesn’t depends on electrolyte disbalance.

    Evidence is growing that the equilibrium between reactive oxygen species and antioxidants plays a vital role in women's reproductive health. The objective of this study was to evaluate variations in serum antioxidant concentrations across the menstrual cycle and associations between antioxidants and reproductive hormones and anovulation among healthy women. The BioCycle Study, a prospective cohort, followed 259 women aged 18-44 y for up to 2 menstrual cycles. Serum fat-soluble vitamin and micronutrient (α-tocopherol, γ-tocopherol, retinol, lutein, lycopene, and β-carotene), ascorbic acid, and reproductive hormone concentrations were measured 5-8 times/cycle. We used weighted linear mixed models to assess associations between antioxidants and hormone concentrations, after adjustment for age, race, body mass index, parity, sleep, pain medication use, total energy intake, concurrent hormones, serum cholesterol, F2-isoprostanes, and other antioxidants. Generalized linear models were used to identify associations with anovulation. Serum antioxidant concentrations varied across the menstrual cycle. Retinol and α-tocopherol were associated with higher estradiol [RR: 1.00 pg/mL (95% CI: 0.67, 1.34 pg/mL); RR: 0.02 pg/mL (95% CI: 0.003, 0.03 pg/mL), respectively] and testosterone [RR: 0.61 ng/dL (95% CI: 0.44, 0.78 ng/dL); RR: 0.01 ng/dL (95% CI: 0.001, 0.01 ng/dL), respectively]. Ascorbic acid was associated with higher progesterone (RR: 0.15 ng/mL; 95% CI: 0.05, 0.25 ng/mL) and with lower follicle-stimulating hormone (RR: -0.06 mIU/mL; 95% CI: -0.09, -0.03 mIU/mL). The ratio of α- to γ-tocopherol was associated with an increased risk of anovulation (RR: 1.03; 95% CI: 1.01, 1.06). These findings shed new light on the intricate associations between serum antioxidants and endogenous hormones in healthy premenopausal women and support the hypothesis that concentrations of serum vitamins affect steroidogenesis even after adjustment for oxidative stress. © 2016 American

    Objective: In the present study we evaluated the paraoxonase activity and protein thiols level in south Indian population with newly diagnosed hyperlipidemia. Methods: The study was conducted on 55 newly diagnosed hyperlipidemic pa-tients and 57 healthy controls. Serum paraoxonase activity and protein thiols were estimated by spectrophotometeric method and lipid profile by enzymatic kinetic assay method. Results: Serum paraoxonase activity, protein thiols and high density lipoprotein levels were low and total cholesterol, triglycerides and low density lipoprutein levels were high in patients with hyperlipidemia compared to healthy controls ( P < 0.01 ). Serum paranxonase activity correlated positively with protein thiols and high density lipoprotein (P<0.01). Conclusion: Decreased paraoxonase activity and protein thiols were found in patients with hyperlipi-demia. This may indicate the susceptibility of this population to accelerated atherogenesis and protein oxidation.

    Values of serum biochemistry were obtained for 33 adult (16 male and 17 female) and six juvenile (four male and two female) collared peccaries collected by trapping and drugging animals from southern Texas during the period July through September 1982. Only cholesterol and aspartate aminotransferase concentrations differed significantly with respect to sex. Juvenile peccaries had significantly lower concentrations of total protein and globulins, but had higher concentrations of glucose, triglycerides, alkaline phosphatase, alanine aminotransferase, and calcium, and a higher albumin/globulin ratio than did adults. Effects of method of capture on biochemical attributes of serum from five gunshot and nine trapped adult peccaries collected from a single herd during March 1983 also were examined. Trapped peccaries had significantly higher levels of serum urea nitrogen, urea nitrogen/creatinine ratio, glucose, and chloride concentrations. Levels of uric acid, calcium, and potassium were significantly lower among the trapped animals.

    Introduction: Gestational diabetes mellitus (GDM) is defined as any degree of glucose intolerance with onset or first recognition during pregnancy.[1] Pregnancy is a unique situation in which there is a physiological temporary increase in insulin resistance (IR). The mechanisms responsible for the gestational-induced IR are not completely understood. The current study was undertaken to compare adiponectin levels during 24–28 weeks period of gestation in drug-naive newly diagnosed GDM women with a cohort of normoglycemic pregnant women. Subjects and Methods: A total of 47 pregnant women in the age group of 18–40 years were included in this cross-sectional study, of which 13 were GDM cases and 34 were normoglycemic controls. Serum adiponectin level was analyzed by enzyme-linked immunosorbent assay. Results: The mean adiponectin level was 16.92 ng/ml (standard deviation [SD] = 2.78) and 19.38 ng/ml (SD = 2.71) in case and control groups, respectively, and the difference was found to be statistically significant (P = 0.008). Conclusion: Our study demonstrated decreased serum adiponectin levels in women with GDM when compared with age- and body mass index-matched euglycemic pregnant women. PMID:27867874

    A 58-year-old woman, who had undergone total gastrectomy for early gastric cancer 9 years previously, visited the outpatient clinic complaining of progressive difficulty in walking for 15 d. Laboratory examinations showed macrocytic anemia and a decreased serum vitamin B12 concentration and increased serum concentrations of folate, vitamin E and copper. Magnetic resonance imaging showed multifocal high signal intensities along the posterior column of the cervical and thoracic spinal cord. Treatment consisted of intramuscular injections of vitamin B12 for 7 d, which increased her serum level of vitamin B12 to normal. This was followed by weekly intramuscular injections of vitamin B12 for another 2 wk and oral administration of vitamin B12 three times per day. After comprehensive rehabilitation for 4 wk, she showed sufficient improvements in strength and ataxic gait, enabling her to return to her normal daily activities. PMID:27729749

    Full Text Available Hematological and biochemical values are important for diagnosis of clinical signs, showing how disease processes change. This is the first report to demonstrate hematological and serum biochemical values of white ibis (Threskiornis melanocephalus in Thailand, which are rare species in tropical countries. The study was carried out in ten healthy white ibises (male, n=5; female, n=5, at the age of 4 years from Khow Khoew Open Zoo, Chon Buri province, Thailand. The results revealed the following information: total red blood cell, hemoglobin concentration, packed cell volume, mean corpuscular volume, mean corpuscular hemoglobin, mean corpuscular hemoglobin concentration, total white blood cell, percentage of lymphocyte,percentage of heterophil, percentage of monocyte, percentage of eosinophil, percentage of basophil and thrombocyte of white ibis were 2.78±0.70 × 106 cells/µl, 18.75±1.32 g/dl, 46.00±3.59%, 173.51±38.52 fl, 70.73 ±15.42 g/dl, 40.82±1.65 pg, 1.49± 0.66 × 104 cells/µl, 89.70±6.40%, 8.50±6.34%, 0.50±0.97%, 0.90±1.29%, .30±0.95% and 16.2±0.49 × 103 cells/µl, respectively. Serum biochemistry values i.e. serum glucose, serum creatinine, serum glutamic oxaloacetic transaminase, and serum glutamic pyruvic transaminase of white ibis were 12.55±1.90 mmol/dl, 69.95±13.05 mmol/l, 204.82±56.76 IU/L and 30.43±8.66 IU/L, respectively. Hematological and biochemical values between males and females white ibis were not significantly different (P>0.05.

    Background Bilirubin is the end product of heme catabolism and has strong antioxidant properties.Serum bilirubin levels are reported to be reduced in patients with multiple sclerosis (MS) and neuromyelitis optica (NMO).The pathophysiology of optic neuritis (ON) resembles that of MS; however,the role of endogenous bilirubin in ON is unclear.The aim of this study is to measure serum bilirubin levels in patients with ON,and to investigate the correlation between ON and serum antioxidant status of bilirubin.Methods Serum levels of bilirubin were measured in 42 patients with ON,50 patients with multiple sclerosis (MS),48 patients with neuromyelitis optica (NMO) and 48 healthy control subjects.Results Serum total bilirubin (Tbil),direct bilirubin (Dbil) and indirect bilirubin (Ibil) levels in patients with ON were significantly lower than those in the healthy controls.However,no statistical significance was found between levels in the ON and MS,ON and NMO,and MS and NMO groups.In patients with ON,serum Tbil,Dbil,and Ibil levels were lower in those with recurrence or those with ON for a longer duration (>1 year).Moreover,Tbil,Dbil,and Ibil concentrations were lower in patients with papillitis than in those with retrobulbar type ON,but the differences were not statistically significant.Conclusions Low antioxidant status may exist in patients with ON.But serum levels of Tbil,Dbil,and Ibil did not correlate with clinical presentations,such as recurrence,duration of disease and subtypes of ON.Low antioxidant status already existed in MS or NMO patients before systemic symptoms appeared.

    Salivary cortisol measurement is used as a practical surrogate for serum free cortisol. However, parotid tissue harbors 11β-hydroxysteroid dehydrogenase (11β-HSD2) activity converting cortisol to cortisone. This study was designed to assess the impact of parotid 11β-HSD2 activity on the measurement of salivary cortisol. PATIENTS, DESIGN, AND OUTCOME MEASURES: Study participants with changes in circulating corticosteroid-binding globulin (CBG) (±oral contraceptive, functionally CBG null) and controls were studied during adrenal stimulation by ACTH and postoral and iv hydrocortisone administration. Simultaneous serum and saliva samples were collected for the measurement of total serum cortisol (SerF) by immunoassay, and unbound cortisol and cortisone in serum (FreeF and FreeE) and saliva (SalF and SalE) by liquid chromatography-tandem mass spectrometry. ACTH stimulation increased SerF, FreeF, SalF, SalE, but not FreeE in all individuals. SerF significantly decreased after stopping oral contraceptive administration, but FreeF, SalF and SalE remained unchanged. In the hydrocortisone administration study, individual FreeF and SalE curves were nearly identical and SalE closely reflected FreeF in all participants, irrespective of CBG changes. The highest correlation in all (n = 537) matched serum-saliva samples was between SalE and FreeF (r = 0.95, P cortisone. We have shown that salivary cortisone closely reflects free serum cortisol after adrenal stimulation and hydrocortisone administration and is unaffected by CBG changes. Salivary cortisone has potential as a useful surrogate for serum free cortisol in research and clinical assessment, and further research in states of chronic glucocorticoid excess is now needed.

    Full Text Available Background: Taurine is an abundant amino acid in human cells, promoting ocular and biliary health, which is also used to treat congestive heart failure, hypertension, and hepatitis. Recently, taurine-enriched energy drinks have become popular with young adults, but the effects of taurine on serum lipids in young adults are unknown. Objective: We studied the influence of oral administration of taurine on serum lipid levels in healthy young women. Methods: Ten healthy young women with a mean body mass index of 20.0kg/m2, apolipoprotein E (apoE phenotype 3/3 and normal menstrual cycles participated. Each subject was instructed to orally ingest 1g of taurine powder after each meal (3g/day in addition to their usual diets during one menstrual cycle. Before and at the end of taurine intake, physical measurements and blood collection were performed in the morning after a 12-h fast, and 3-day weighted dietary records were obtained. Concentrations of serum lipids, apolipoproteins, and fatty acids in the serum phospholipid fraction were measured. Results: The subjects showed good compliance with taurine intake and none reported adverse effects during the experimental period. After taurine intake, concentrations of total cholesterol, low density lipoprotein cholesterol (LDL-C, free cholesterol, and apolipoprotein B (apoB increased (p<0.05, while phospholipids tended to increase (p=0.051. Fatty acids in the serum phospholipid fraction also significantly increased (p<0.05. However, triglyceride, remnant-like particle cholesterol, remnant-like particle triglyceride, apoE, the apolipoprotein A-1 (apoA- 1/apoB ratio and the LDL-C/apoB ratio were unchanged. Furthermore, body weight was significantly increased (p<0.01, but did not correlate with changes either in serum lipids or nutrient intakes. Conclusion: These results suggest that high taurine intake affects lipoprotein metabolism and increases serum lipids in slightly lean young women.

    Some authors have investigated the effects of oxidative stress in some process such as undergoing laparoscopic. However, the effect of upper gastrointestinal system endoscopy process on oxidative stress is unclear. We evaluated the short-term effect of upper gastrointestinal system endoscopy process on oxidative stress. Thirty patients who underwent endoscopy process and 20 healthy controls were enrolled in the prospective study. Serum total antioxidant capacity and total oxidant status measurements were measured before and after endoscopy process. The ratio percentage of total oxidant status to total antioxidant capacity was regarded as oxidative stress index. Before endoscopy process, serum total antioxidant capacity levels were higher, while serum total oxidant status levels and oxidative stress index values were lower in patients than controls, but this difference was not statistically significant (all, p > 0.05). After endoscopy process, serum total antioxidant capacity and total oxidant status levels were significantly higher in patients than before endoscopy process (both, p oxidative stress index values were slight higher in patients but this difference was not statistically significant (p > 0.05). We observed that serum TAC and TOS levels were increased in patients who underwent endoscopy process after endoscopy process. However, short-time upper gastrointestinal system endoscopy process did not cause an important change in the oxidative stress index. Further studies enrolling a larger number of patients are required to clarify the results obtained here.

  15. Piezoelectric microcantilever serum protein detector

    Capobianco, Joseph A.

    The development of a serum protein detector will provide opportunities for better screening of at-risk cancer patients, tighter surveillance of disease recurrence and better monitoring of treatment. An integrated system that can process clinical samples for a number of different types of biomarkers would be a useful tool in the early detection of cancer. Also, screening biomarkers such as antibodies in serum would provide clinicians with information regarding the patient's response to treatment. Therefore, the goal of this study is to develop a sensor which can be used for rapid, all-electrical, real-time, label-fee, in-situ, specific quantification of cancer markers, e.g., human epidermal receptor 2 (Her2) or antibodies, in serum. To achieve this end, piezoelectric microcantilever sensors (PEMS) were constructed using an 8 mum thick lead magnesium niobate-lead titanate (PMN-PT) freestanding film as the piezoelectric layer. The desired limit of detection is on the order of pg/mL. In order to achieve this goal the higher frequency lateral extension modes were used. Also, as the driving and sensing of the PEMS is electrical, the PEMS must be insulated in a manner that allows it to function in aqueous solutions. The insulation layer must also be compatible with standardized bioconjugation techniques. Finally, detection of both cancer antigens and antibodies in serum was carried out, and the results were compared to a standard commercialized protocol. PEMS have demonstrated the capability of detecting Her2 at a concentration of 5 pg/mL in diluted human serum (1:40) in less than 1 hour. The approach can be easily translated into the clinical setting because the sensitivity is more than sufficient for monitoring prognosis of breast cancer patients. In addition to Her2 detection, antibodies in serum were assayed in order to demonstrate the feasibility of monitoring the immune response for antibody-dependent cellular cytotoxicity (ADCC) in patients on antibody therapies

    2013-05-01

    Full Text Available       Aim: We aimed to investigate the activity of ADA isoenzymes in serum of rats with lung contusion Material and Method: Lung contusion was induced in twelve male wistar albino rats by dropping a cylindrical weight from a height of 50 cm with a mobile platform positioned over the thorax. Rats were killed at 24 hour (n=6 and 72 hour (n=6 after contusion. ADA isoenzymes were measured in serum traumatic and control (n=6 (uninjured rats. Results: Our results indicated that serum total ADA activities were significantly decreased at 72 h after contusion. There was a significant decreased in ADA1 activity at 24 and 72 h after contusion when compared with controls. On the other hand, the increase in the ADA2 activity at 24 h and 72 h was not statistically significant. Discussion: In conclusion, serum ADA2 became predominant isozyme because of the inflammatory response in the lung contusion. However, further studies are needed to elucidate the regulatory mechanisms that effect the activity of serum ADA1.

    Full Text Available Aim of our study was to investigate the effects of exposure to industrial noise on serum lipid profile among workers who are exposed to noise at work. In a historical cohort study, we recruited 154 and 146 male workers as high and low level noise exposure groups respectively. We defined workers with at least one year exposure to noise level more than 90 dB as high exposure group, and those with exposure to less than 80 dB as low exposure group. Afterwards, in the fasting blood specimens of participants we measured serum Triglyceride (TG, total Cholesterol (TC, high and low density lipoprotein (HDL and LDL. Mean of TG, TC, HDL and LDL for low exposure group were 148, 189, 38 and 103 mg/dl and for high exposure group were 237, 189, 37 and 104 mg/dl respectively. Mean serum TG between two groups was different. Even after adjustment for age, BMI, smoking and work hours per week, serum TG among high exposure group was 89 mg/dl higher than low exposure group and this difference was statistically significant (P=0.00. There was no significant difference between two groups in TC, LDL and HDL levels. This study did not find a statistically significant relationship between exposure to noise and serum TC, LDL and HDL, but TG in two groups was different and this difference was statistically significant.

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

    Full Text Available Regarding the high prevalence of hyperlipidaemia, which is one of the major risk factors of cardiovascular disease, and uncertain reports about the relation between periodontal disease and serum lipid profile, this study was conducted to assess this relation. The historical cohort study was conducted on 52 cases including 26 persons with chronic periodontitis as case group, and 26 healthy subjects as control group. Both groups had the same age and weight ranges, sex, and diet, without any periodontal treatment history in the past six months, underling systemic disease such as diabetes, anti-hyperlipidemic drugs or active tobacco smoking history. Low Density Lipoprotein (LDL, High Density Lipoprotein (HDL, Triglyceride (TG and Total Cholesterol (CHOL were measured by direct enzymatic assay. TG level was 128.4±71.1 mg/dl in control group and 165.2± 83.7 in case group indicating a significantly higher level in case group (P<0.05. In control group, 30.8 percent and in case group, 61.5 percent had abnormal serum cholesterol levels, which presents a significantly higher level in case group (P<0.03. Other serum level indices did not show any significant difference. Although it seems that patients with chronic periodontal disease are more susceptible to hyperlipidemia, it is doubtful that the former causes an increase in serum lipid levels, so we suggest studying the effects of treating chronic periodontitis on serum lipid level.

    The administration of multivitamins to patients receiving home parenteral nutrition (HPN) was decreased from once daily to three times weekly during the parenteral multivitamin shortage in 1997. Blood vitamin levels were measured to examine whether the decrement in the infused vitamins affected the levels. Six patients with normal renal and liver function, receiving HPN for 6 months to 10 years, were studied 6 months after the institution of 10 mL of multivitamins thrice weekly. Two patients with renal insufficiency who required hemodialysis and HPN were also studied. Multivitamin administration was eliminated in one patient and was reduced to once weekly when elevated pyridoxine levels were found in association with possible neurotoxicity. Five of the six patients with normal renal function had low serum ascorbic acid levels. Serum riboflavin levels were found to be low in one patient, serum pyridoxine was low in one, serum retinoids were low in three, and serum niacin was low in one. There were no clinically obvious untoward effects caused by the vitamin deficiencies. Each of the dialysis patients had elevated serum pyridoxine levels and had some neurologic disturbance (peripheral neuropathy, involuntary movements). The serum pyridoxine levels fell to normal in each after the cessation or decrease of the multivitamin preparation. Ascorbic acid levels were low in one patient and fell into abnormally low levels in the other when the parenteral multivitamins were reduced, but they corrected with the separate administration of intravenous vitamin C. In conclusion, the reduced administration of multivitamins in 1997 resulted in diminished ascorbic acid levels in seven of eight patients receiving total parenteral nutrition. Less often, low levels of retinoids, niacin, pyridoxine, and riboflavin were seen. Patients with chronic renal failure receiving HPN with multivitamins may develop elevated pyridoxine levels, which might result in neurologic sequelae.

    Objective:To explore the clinical value of serum amylase, serum trypsinogen-2, IL-10 and platelet activating factor detection in the diagnosis of post-ERCP pancreatitis.Methods:A total of 256 patients with ERCP were selected in our hospital of the digestive department of internal medicine from January 2015 to December 2015. According to different symptoms, signs, serum amylase and pancreatic CT examination results after ERCP, the subjects were divided into three groups: control group, hyperlipidemia group and PEP group. Serum trypsinogen-2, IL-10, platelet activating factor were detected.Results:There were statistically significant differences in serum trypsinogen-2, IL-10, platelet activating factor among control group, hyperlipidemia group and PEP group patients with serum amylase (Fgroup = 269.578, 139.492, 145.637, 126.891, allP = 0.000), and the value of PEP group was the highest. There were statistically significant differences in serum trypsinogen-2, IL-10, platelet activating factor at different time point (Ftime = 602.506, 494.375, 462.512, 239.564, allP = 0.000), the serum amylase level in the patients with hyperlipidemia group reached the highest value after 4 h, but the 24 h was lower than the normal level after operation, the serum amylase in PEP group increased rapidly after 4 h, and the 24 h was still increased after operation; The serum trypsinogen-2, IL-10, platelet activating factor were all highest 4 h after the operation in the hyperlipidemia group and PEP group, and the 24 h after the operation were all decreased. In PEP group, serum amylase, serum trypsinogen-2, IL-10, platelet activating factor 4 h after the operation and 24 h after the operation were significantly higher than those before operation (Finteractive = 28.492, 22.614, 16.573, 7.819, allP = 0.000). In PEP group, the serum amylase had positive correlations with serum trypsinogen-2, IL-10, platelet activating factor (r=0.591, 0.662, 0.681, allP<0.05).Conclusions: Serum amylase

    Our previous studies have shown that mangiferin decreased serum triglycerides and free fatty acids (FFAs) by increasing FFAs oxidation in both animal and cell experiments. This study sought to evaluate the effects of mangiferin on serum lipid profiles in overweight patients with hyperlipidemia. Overweight patients with hyperlipidemia (serum triglyceride ≥ 1.70 mmol/L, and total cholesterol ≥ 5.2 mmol/L) were included in this double-blind randomized controlled trial. Participants were randomly allocated to groups, either receiving mangiferin (150 mg/day) or identical placebo for 12 weeks. The lipid profile and serum levels of mangiferin, glucose, L-carnitine, β-hydroxybutyrate, and acetoacetate were determined at baseline and 12 weeks. A total of 97 participants completed the trial. Compared with the placebo control, mangiferin supplementation significantly decreased the serum levels of triglycerides and FFAs, and insulin resistance index. Mangiferin supplementation also significantly increased the serum levels of mangiferin, high-density lipoprotein cholesterol, L-carnitine, β-hydroxybutyrate, and acetoacetate, and increased lipoprotein lipase activity. However, there were no differences in the serum levels of total cholesterol, low-density lipoprotein cholesterol, serum glucose, and insulin between groups. Mangiferin supplementation could improve serum lipid profiles by reducing serum triglycerides and FFAs in overweight patients with hyperlipidemia, partly due to the promotion of FFAs oxidation.

    Although fasting and refeeding reveal the existence of age-related changes in carbohydrate and lipid metabolism, the effects of aging on mineral metabolism in refed animals are unknown. We therefore investigated hormonal regulation of calcium metabolism in young (4 months) and old (26 months) male rats fasted for 48 hours and then refed for 4 or 24 hours. Serum concentrations of total and ionized calcium and parathormone were similar in control young and old rats. Serum calcitonin level was higher, and the concentrations of albumin and inorganic phosphate and alkaline phosphatase activity were lower in fed old rats. In young fasted rats, the serum ionized and total calcium was decreased, and phosphate concentration was increased. In old rats, fasting resulted in the increase of serum parathormone level. Fasting reduced serum alkaline phosphatase activity to a similar extent in both age groups. In young rats, refeeding for 24h normalized serum calcium and phosphate levels and alkaline phosphatase activity, and decreased serum concentrations of PTH and calcitonin. In old refed rats, serum calcitonin concentration was raised by 77% compared to fed or fasted animals, whereas parathormone levels were normalized. Our results indicate that old fasted or refed rats maintain normal serum calcium concentration in a different way than young animals, possibly through the increase in serum levels of parathormone and/or calcitonin. Thus, dietary manipulations such as fasting and refeeding constitute an interesting model for the investigation of the effects of aging on the hormonal regulation of serum calcium level.

    Full Text Available Introduction: Assam is considered as a vulnerable state for malarial infection. Malarial patient exhibit several divergent values in their blood cell parameter as well as changes in concentration of normal serum ferritin level. The study was intended to observe the concentration of serum ferritin level and estimation of hematological feature among malaria patients in Assam. Materials and Methods: During the period from August 2012 to January 2013, a total of 77 blood samples have been collected from 77 individuals suspected with malaria from different malaria endemic districts of Assam. Results: A total of 36 cases were found to be malaria positive of which 25 were symptomatic and 11 were asymptomatic. Overall the percentage of parasitaemia was found 0.1-15%. Distribution of malaria cases was observed in all age groups and both the sexes. Hematological values among the malaria positive patients revealed that about 89% were having anaemia, 66.67% with Thrombocytopenia and 47% Lymphocytopenia. Iron deficiency anaemia was recorded in 63.87% of the patients. Other haematological status includes 30.56% individual with Granulocytosis and 50.00% subjects with low Mean platelet volume etc. Results also showed that the serum ferritin level in the malaria positive population ranged in from 70 ng/ml to 300 ng/ml, with a mean value of 114 ng/ml. Conclusion: In our study, hematological abnormality and low serum ferritin level is observed as an imperative marker for identification of malaria patients.

    Malnutrition is reported to be an inevitable consequence of total gastrectomy, although there are few data to support this contention. Six patients of median age 63 years underwent total gastrectomy for malignancy. At follow-up (median 45 months, range 25-60 months) each patient was clinically tumour-free and underwent dietary assessment, faecal fat and nitrogen measurement and routine haematological testing. Protein and fat stores, measured by neutron activation analysis and the tritiated water dilution technique, were compared with the same measurements made before operation and with predicted values. Mean (s.d.) dietary intake (2224(381) kcal day-1 and 81(15)g protein day-1) met the patients' estimated requirements. Mean(s.d.) serum albumin and faecal nitrogen values were normal but there was notable steatorrhoea (21(17) g day-1). Body composition measurements revealed profound deficiencies of body-weight (P less than 0.02), protein (P less than 0.01) and fat (P less than 0.02) before operation which were not corrected by an apparently curative total gastrectomy (P less than 0.05), although further deterioration was prevented.

    This study investigated the effects of Drynaria total flavonoids on cathepsin K serum concentrations and gene expression, biomechanics and bone mineral density (BMD) of the tibial shaft in ovariectomized rat models of osteoporosis, and mechanism in the prevention and cure of osteoporosis. Seventy-two female Sprague-Dawley rats were divided into six groups. The rats in each group were subjected to gastric lavage after the model was established. The tibial shaft of the right hindlimb was obtained to measure the BMD. Serum cathepsin K concentrations were determined. The cathepsin K mRNA expression was also determined using fluorescent quantitative polymerase chain reaction. The three-point bending method was performed to measure the maximum bending load of the tibial shaft. The total flavonoid and normal groups had significant differences in serum cathepsin K concentrations compared with that in the estrogen group (Ptotal flavonoid and sham-operated groups also showed significant differences in cathepsin K mRNA expression compared with that in the normal group (Ptotal flavonoid group was significantly different from that in the estrogen group (Ptotal flavonoid group elicited a better effect on BMD than that by the medium- and low-dose groups (Ptotal flavonoids inhibited the serum cathepsin K concentration and increased the maximum bending load of the tibial shaft in ovariectomized rats.

    Carnitine is a vitamin-like compound that plays important roles in fatty acid β-oxidation and the control of the mitochondrial coenzyme A/acetyl-CoA ratio. However, carnitine is not added to ordinary enteral nutrition or total parenteral nutrition. In this study, we determined the serum carnitine concentrations in subjects receiving ordinary enteral nutrition (EN) or total parenteral nutrition (TPN) and in patients with inflammatory bowel diseases to compare its levels with those of other nutritional markers. Serum samples obtained from 11 EN and 11 TPN patients and 82 healthy controls were examined. In addition, 10 Crohn's disease and 10 ulcerative colitis patients with malnutrition who were barely able to ingest an ordinary diet were also evaluated. Carnitine and its derivatives were quantified using liquid chromatography-tandem mass spectrometry (LC-MS/MS). The carnitine concentrations in EN and TPN subjects were significantly lower compared with those of the control subjects. Neither the serum albumin nor the total cholesterol level was correlated with the carnitine concentration, although a significant positive correlation was found between the serum albumin and total cholesterol levels. Indeed, patients with CD and UC showed significantly reduced serum albumin and/or total cholesterol levels, but their carnitine concentrations remained normal. In conclusion, only a complete blockade of an ordinary diet, such as EN or TPN, caused a reduction in the serum carnitine concentration. Serum carnitine may be an independent biomarker of malnutrition, and its supplementation is needed in EN and TPN subjects even if their serum albumin and total cholesterol levels are normal.

    Chronic mountain sickness (CMS), a lack of adaptation to altitude characterized by excessive erythrocytosis (EE), is a health problem associated with life at high altitude. The erythropoietic process is regulated by both erythropoietin and testosterone. Zinc (Zn) is known to be related with testosterone and hemoglobin levels; meanwhile, nitric oxide was also associated with adaptation to high altitude. The aim of this study was to determine the relationship of hemoglobin and CMS score with serum levels of zinc, total testosterone (TT), calculated free testosterone (cFT), bioavailable testosterone (BAT), hemoglobin, and nitric oxide in men at high altitude with or without EE. Men residing in Lima (150 m) and Cerro de Pasco (4,340 m), Peru, were divided into three groups: (1) low altitude, (2) high altitude without EE (hemoglobin < 21 g/dl), and (3) high altitude with EE (hemoglobin ≥ 21 g/dl). Adjusted multivariable regression models showed that serum testosterone (total or free) and Zn levels were independently correlated with increased hemoglobin levels. Similarly, hemoglobin was positively related with signs/symptoms of CMS; however, both increased the serum Zn and the nitric oxide levels correlated with reduced risk for signs/symptoms of CMS. In conclusion, higher serum testosterone levels and Zn levels were associated with EE, and low scores of signs/symptoms of CMS were associated with higher Zn and nitric oxide levels.

    Dong Lin

    Full Text Available PURPOSE: Excessive brain iron accumulation contributes to cognitive impairments in hepatitis B virus (HBV-related cirrhotic patients. The underlying mechanism remains unclear. Hepcidin, a liver-produced, 25-aminoacid peptide, is the major regulator of systemic iron metabolism. Abnormal hepcidin level is a key factor in some body iron accumulation or deficiency disorders, especially in those associated with liver diseases. Our study was aimed to explore the relationship between brain iron content in patients with HBV-related cirrhosis and serum hepcidin level. METHODS: Seventy HBV-related cirrhotic patients and forty age- sex-matched healthy controls were enrolled. Brain iron content was quantified by susceptibility weighted phase imaging technique. Serum hepcidin as well as serum iron, serum transferrin, ferritin, soluble transferrin receptor, total iron binding capacity, and transferrin saturation were tested in thirty cirrhotic patients and nineteen healthy controls. Pearson correlation analysis was performed to investigate correlation between brain iron concentrations and serum hepcidin, or other iron parameters. RESULTS: Cirrhotic patients had increased brain iron accumulation compared to controls in the left red nuclear, the bilateral substantia nigra, the bilateral thalamus, the right caudate, and the right putamen. Cirrhotic patients had significantly decreased serum hepcidin concentration, as well as lower serum transferring level, lower total iron binding capacity and higher transferrin saturation, compared to controls. Serum hepcidin level negatively correlated with the iron content in the right caudate, while serum ferritin level positively correlated with the iron content in the bilateral putamen in cirrhotic patients. CONCLUSIONS: Decreased serum hepcidin level correlated with excessive iron accumulation in the basal ganglia in HBV-related cirrhotic patients. Our results indicated that systemic iron overload underlined regional

    Smoking may modify the appetite, and consequently affect nutrient intake and serum micronutrients. The effect of smoking on vitamin B12 status has been considered in several studies. The research proposed that organic nitrites, nitro oxide, cyanides, and isocyanides of cigarette smoke interfere with vitamin B12 metabolism, and convert it to inactive forms. This research was carried out to determine the serum level of active and inactive forms of vitamin B12 in male smokers in comparison with male nonsmokers. This is a case-control study, in which the participants were 85 male smokers and 85 male nonsmokers. The serum levels of total and active form of vitamin B12 were measured. Dietary intake was recorded by a quantitative food frequency questionnaire and one-day 24-hour dietary recall method. Independent two sample T test was used to compare quantitative variables between the case and control groups. The serum level of total vitamin B12 was not significantly different between two groups, but serum level of active form of vitamin B12 in the smoking group was significantly lower than non-smoking group (Pvitamin B12 in smokers in the Iranian community. The results of this study identified that serum level of total vitamin B12 might be not different between smoking and non-smoking people, but the function of this vitamin is disturbed in the body of smokers through the reduction of serum level of active form of vitamin B12.

    Results: The study observed an increased level of serum adenosine deaminase, malondialdehyde and decreased levels of total antioxidant capacity in type 2 diabetes mellitus compared to controls. Serum adenosine deaminase levels in type 2 diabetics were 50.77 +/- 6.95 and in controls was 17.86 +/- 4.04. Serum Malondialdehyde levels in type 2 diabetics was 512.13 +/- 70.15 and in controls was 239.32 +/- 23.97. Serum total antioxidant levels in type 2 diabetics was 0.39+/-0.15 and in controls was 1.66+/-0.25. Positive correlation was seen between serum adenosine deaminase and malondialdehyde and it was statistically significant. Statistically significant negative correlation was seen between serum adenosine deaminase and total antioxidant capacity. Conclusion: Adenosine deaminase can be used as oxidative stress marker. Their increased levels indicate oxidative stress in type 2 diabetes mellitus. Therefore, estimation of serum adenosine deaminase levels help in early prediction and prevention of long term complications occurring due to oxidative stress in diabetics, thereby decreasing the mortality and morbidity in them.

    Full Text Available Background: Vascular endothelial dysfunction is considered central to the pathogenesis of hypertensive disorders of pregnancy (HDP. Serum level of neutrophil gelatinase-associated lipocalin (NGAL is closely related to endothelial injury. The aim of this study was to examine the correlation of serum NGAL with disease severity in HDP. Materials and Methods: This prospective case-control study was carried out for one year. After informed consent, ethical clearance, total 1,850 pregnant women were screened. Analysis was performed on 142 cases of HDP and 31 healthy controls. Quantitative measurement of serum NGAL levels was done by the enzyme linked immunosorbent assay (ELISA technique, by using sandwich ELISA kit. Results: Mean serum NGAL value in patients with oliguria was significantly higher when compared with non-oliguric patients (P < 0.001. Serum NGAL had a positive correlation with systolic blood pressure (r ~ 0.5973, diastolic blood pressure (r ~ 0.6195, blood urea (r ~ 0.4392, serum creatinine (r ~ 0.6112, serum uric acid (r ~ 0.3878. Sensitivity and specificity of serum NGAL using a cut-off value of 545 pg/ml, for the diagnosis of HDP, was 97.89% and 93.55% respectively, using 95% confidence interval. Conclusion: Between the two groups, we found that serum NGAL had a positive correlation with disease severity and better sensitivity and specificity in the evaluation of HDP.

    Ferritin is highly expressed in many cancer types. Although a few studies have reported an association between high serum ferritin levels and an increased risk of prostate cancer, the results are inconsistent. Therefore, we performed a large case-control study consisting of 2002 prostate cancer patients and 951 control patients with benign prostatic hyperplasia (BPH). We found that high ferritin levels were positively associated with increased serum prostate-specific antigen (PSA) levels and prostate cancer risk; each 100 ng/ml increase in serum ferritin increased the odds ratio (OR) by 1.20 (95% CI: 1.13-1.36). In the prostate cancer group, increased serum ferritin levels were significantly correlated with higher Gleason scores (p serum PSA values had even higher predictive accuracy among prostate cancer patients with serum ferritin levels > 400 ng/ml (Gleason score + total PSA correlation: r = 0.38; Gleason score + free PSA correlation: r = 0.49). Moreover, using immunohistochemistry, we found that prostate tissue ferritin levels were significantly higher (p ferritin levels were also highly correlated with serum ferritin when patients were classified by cancer severity (r = 0.81). Importantly, we found no correlation between serum ferritin levels and the inflammation marker C-reactive protein (CRP) in prostate cancer patients. In conclusion, serum ferritin is significantly associated with prostate cancer and may serve as a non-invasive biomarker to complement the PSA test in the diagnosis and prognostic evaluation of prostate cancer.

    Full Text Available OBJECTIVE: The aim of this study was to examine serum prealbumin (PA levels in patients with tuberculosis and lung cancer, and to evaluate the correlations of serum PA levels with clinicopathological characteristics. METHOD: Total 760 patients were included in the study: 320 patients with tuberculosis, 320 patients with lung cancer, and 120 healthy subjects. Serum PA was detected using a biochemical analyzer to determine the value of serum PA in the diagnosis and therapeutic response of tuberculosis. RESULTS: Compared to lung cancer and healthy individuals, TB patients were more frequent in suffering from low serum PA (75.0% vs.30.9% vs.6.7%,P20 mm/h and smoking status (≥ 20 pack × years were associated with low serum PA levels of TB patients, while ECOG performance status (≥ 2 was associated with low serum PA levels of lung cancer patients. The change of serum PA levels was in accordance with the therapeutic effects of anti-TB drugs, which might present a valuable and objective indicator for monitoring the therapeutic effects of TB drugs on TB patients. CONCLUSION: Low serum prealbumin levels are very common in TB patients and can be served as a potential indicator for differential diagnosis of lung cancer and monitoring the therapeutic effects of TB drugs.

    The purpose of this study was to investigate the relationship between serum taurine level and serum adiponectin or leptin levels in high-fat diet-induced obesity rats. Five-week-old male Sprague-Dawley rats were randomly divided into three groups for a period of 8 weeks (normal diet, N group; high-fat diet, HF group; high-fat diet + taurine, HFT group). Taurine was supplemented by dissolving in feed water (3% w/v), and the same amount of distilled water was orally administrated to N and HF groups. In serum, adiponectin level was higher in HFT group compared to HF group. The serum taurine level was negatively correlated with serum total cholesterol (TC) level and positively correlated with serum adiponectin level. These results suggest that dietary taurine supplementation has beneficial effects on total cholesterol and adiponectin levels in high-fat diet-induced obesity rats.

    2011-08-01

    Full Text Available Atherosclerosis is the leading cause of death in the developed world1.In Pakistan; the disease seems to follow an accelerated course with ischaemic events occurring a decade earlier than those reported worldwide2. While many risk factors of cardiovascular diseases are well established, many are still under evaluation; like homocysteine, which is now being considered an independent risk factor for cardiovascular diseases3.Homocysteine is a sulfur containing amino acid which is not our dietary constituent but is formed by metabolism of methionine, another amino acid present in our daily protein diet. In case of excess formation of homocysteine as compared to its consumption, it appears in urine if levels are too high3. Normal plasma homocysteine concentration ranges from 5 to 15μmol/litre. Of this, almost 75% is bound to proteins, especially albumin, through disulfide bond. Classification of hyperhomocysteinemia described by Kang SS 4 is followed widely.Moderate hyperhomocysteinemia (15 to 30 μmol/litreIntermediate hyperhomocysteinemia (30 to 100μmol/litreSevere hyperhomocysteinemia (>100 μmol/litre

    Full Text Available Present study was conducted to find out the relationship between serum biochemical profile and postpartum metritis. Mainly serum glucose, total protein, albumin, albumin globulin ratio, blood urea nitrogen (BUN, creatinine and calcium were studied. Colorimetric method was used for quantitative estimation of biochemical profile. Twenty-seven animals with recent history of calving and subsequent metritis were included in the study. On analysis, serum glucose was found to be 22.3 ± 2.18 mg/dl, total protein 6.1 ± 0.51 g/dl, albumin 2.8 ± 0.29 g/dl, BUN 27 ± 0.19 mg/dl, creatinine 1.8 ± 0.13 mg/dl and calcium was 7.0 ± 0.43 mg/dl. On comparison of this result with normal values it was found that glucose and calcium was below the normal level and albumin fraction was less than the globulin. It was concluded that in postpartum metritis, cattle exhibit hypocalcaemia, hypoglycaemia and reduced globulin fraction, whereas total protein, albumin, BUN and creatinine did not exhibit much variation. Ketone bodies were present in urine of 90% of tested animals. [Vet. World 2009; 2(1.000: 27-28

    Intravenous hypnotic propofol and its metabolite are detected in real time during total intravenous anesthesia by an electron ionization mass spectrometer. The mass spectrometer is connected directly to the breathing circuit of an apparatus for inhalational anesthesia. Ratios between the propofol concentrations in expired air and blood serum are measured. It is concluded that real-time noninvasive monitoring of the propofol concentration in blood using electron ionization mass spectrometry is feasible.

    Full Text Available : INTRODUCTION: Hypertension is one of the risk factors for cardiovascular disease and causes progressive damage to kidney in a long term process. Hypertension impairs glomerular function and also leads to subclinical atherogenesis, there is a excretion of low molecular weight compounds like albumin and amylase in urine. This study was conducted to analyze the changes in amylase levels in hypertension. MATERIAL AND METHODS: This is a hospital based study. The patients attending the medicine department were selected for the study. 60 subjects were selected based on history and clinical examination consisting of 30 hypertensive patients and 30 normotensive subjects in the age group 35-60 years. Blood samples collected in vacutainers were analyzed in the clinical biochemistry laboratory. Serum samples were analyzed for total protein, albumin and amylase. RESULT: The study showed a statistically significant change in the levels of serum albumin and amylase. The level of serum albumin was 3.71 ± 0.22 g/dl in cases while it was 4.14 ± 0.20 g/dl in controls. The serum amylase levels were 99.79 ±13.63 U/L in cases while it was 137.76 ± 16.86 U/L in the control. The p-value was 0.0001 which was statistically significant. CONCLUSION: The initial damage to glomerulus can be detected by the alteration in serum amylase values in hypertension. Thus serum amylase can be considered as an early marker for detecting the renal damage in hypertension

    Erythropoietin has been shown to induce neovascularization and protect against ischemic vascular injury. We investigated whether a higher serum erythropoietin (EPO) level is related to better coronary collateral vessel grade. Ninety-nine patients with stable angina pectoris who have at least 1 coronary stenosis of equal to or greater than 70% at coronary angiography were prospectively enrolled. Serum EPO and vascular endothelial growth factor (VEGF) levels were studied. Coronary collateral degree was graded according to the Rentrop method. Patients with grade 2-3 collateral degree were included in the good collateral group and formed Group I. The patients with grade 0-1 collateral degree were included in the poor collateral group and formed Group II. The serum EPO level was significantly higher in the good collateral group (17.3 ± 9.3 mU/mL vs 11.7 ± 5.0 mU/mL; P < 0.001). There was also a positive correlation between serum EPO level and Rentrop score (r = 0.39; P < 0.001). In multivariate analysis, serum EPO level (odds ratio [OR] 1.336; 95% confidence interval [CI], 1.120-1.593; P = 0.001), oxygen saturation (OR 0.638; 95% CI, 0.422-0.963; P = 0.033) and presence of chronic total occlusion (CTO) (OR 26.7; 95% CI, 3.874-184.6; P = 0.001) were independently related to well-developed coronary collaterals. Higher serum EPO level is related to better coronary collateral development. Erythropoietin may have a positive effect on the development of collaterals and may provide a new agent for the treatment strategies to enhance coronary collateral vessel development.

    Alterations of trace element concentrations adversely affect biological processes and could promote carcinogenesis. Only a few studies have investigated the degree of changes in copper and zinc levels in colorectal cancer (CRC). The aim of the present study was to compare the serum copper (Cu) and zinc (Zn) concentrations in patients with CRC from Iran with those of healthy subjects. Cu and Zn concentrations in the serum of 119 cancer patients and 128 healthy individuals were measured by atomic absorption spectrometry. We found a significant decrease in the total mean serum Cu and Zn concentrations in CRC patients as compared with the control group (137.5 ± 122.38 vs. 160.68 ± 45.12 μg/dl and 81.04 ± 52.05 vs. 141.64 ± 51.75, respectively). However, the serum Cu/Zn ratio in the patient group was significantly higher than that measured in the control group (p = 0.00). There was no significant difference in the mean values of serum Cu and Zn concentrations between young (obese cases (132.31 ± 87.43 vs. 103.81 ± 53.72 μg/dl, respectively) (p < 0.05). There was no difference in mean serum Cu and Zn concentrations in patients stratified by the site, stage, or differentiation grade of tumors. Our findings suggest that imbalance in Cu and Zn trace element level is associated with CRC and might play an important role in cancer development among Iranian patients.

    Although several studies have shown an association between ferritin level and hypertension, only a few studies have investigated the longitudinal relationship between them. Thus, we evaluated the incidental risk for hypertension according to baseline ferritin level. A total of 7104 healthy Korean men matched by a propensity score, who had participated in a medical health check-up program in 2005, were followed up from 2005 to 2010. They were divided into four groups according to baseline serum ferritin level (first quartile-fourth quartile). The incidence of hypertension was compared among the four groups, and the Cox-proportional hazard model was used to assess whether the development of hypertension was associated with higher baseline serum ferritin level. A total of 1252 (17.6%) cases had newly developed hypertension during the 26,339.5 person-years of follow-up between 2006 and 2010. The adjusted hazard ratios (HRs) (95% confidence intervals, CIs) for incident hypertension were 1.00 (reference), 1.09 (0.91-1.30), 1.21 (1.01-1.45) and 1.28 (1.07-1.52), respectively (P for trend=0.003) through the quartiles of serum ferritin levels, respectively, after adjusting for multiple confounders. For the log-transformed serum ferritin levels as a continuous variable, adjusted HRs and 95% CIs for HTN were 1.15 (1.02-1.29). Elevated serum ferritin level was independently associated with the incidental risk for hypertension in Korean men. This finding suggests the value of elevated ferritin level as an early predictor of hypertension. Copyright © 2014 Elsevier Ireland Ltd. All rights reserved.

    As women go through menopause, serum estrogen decreases and ferritin increases. Decreased serum estrogen is well known to cause detrimental effects on bone health; however, data on the associations of serum ferritin with BMD before and after menopause are still lacking. Therefore, this study aimed to investigate the association between serum ferritin levels and BMD in premenopausal and postmenopausal Korean women. This study was performed using data from the 2008-2010 Korean National Health and Nutrition Examination Survey, including 7300 women (4229 premenopausal and 3071 postmenopausal). BMD was measured using dual X-ray absorptiometry at the femur and the lumbar spine, and serum ferritin levels were measured by chemiluminescent immunoassay. Median serum ferritin levels in postmenopausal women were higher than those in premenopausal women despite the same age ranges. Serum ferritin levels were only significantly correlated with BMD on the lumbar spine (β = -0.189, p-value = 0.005) in premenopausal women after adjusting confounding factors. Additionally, BMD on the lumbar spine had tended to decrease as serum ferritin quartiles increase (P for trend = 0.035) in premenopausal women after adjusting confounding factors. On the other hand, there were no significant associations between serum ferritin levels and BMD on the total femur and, femur neck in premenopausal women, and BMD on the total femur, femur neck, and lumbar spine in postmenopausal women. Increased serum ferritin levels were significantly associated with BMD in premenopausal women, particularly on the lumbar spine, but not in postmenopausal women.

    Full Text Available OBJECTIVE: To investigate the link between serum interleukin-18 (IL-18 levels and physical activity in Japanese men. METHODS: A total of 81 men (45.7±17.6 years old was enrolled in this cross-sectional investigation study. We assessed anthropometric and body composition parameters. Serum IL-18 levels, physical activity by uniaxial accelerometers, peak oxygen uptake and metabolic risk parameters were also evaluated. RESULTS: Serum IL-18 levels were 179.4±84.7 pg/mL. Physical activity evaluated by Σ[metabolic equivalents × h per week (METs⋅h/w]was significantly and negatively correlated with serum IL-18 levels (r = -0.252, p = 0.0235. These associations remained even after adjusting for age, peak oxygen uptake and other confounding factors. CONCLUSION: Serum IL-18 levels were closely associated with physical activity independent of peak oxygen uptake in Japanese men.

    The in vivo transfer of serum proteins to the human intestinal lumen was characterized by crossed immunoelectrophoretic analyses of intestinal perfusates from four healthy volunteers. Serum proteins with molecular masses below 100 kDa and the immunoglobulins were found in human jejunal perfusates....... Larger serum proteins were either absent (alpha and beta lipoproteins) or present in small amounts (alpha 2-macroglobulin, haptoglobulin and ceruloplasmin). These results demonstrate the existence of a selective transfer of serum proteins to the intestinal lumen under physiological conditions....... The intestinal clearance rate was 0.1 ml serum per hour per 10 cm jejunum for albumin, prealbumin, alpha 1-antitrypsin, orosomucoid, transferrin and haemopexin. The rate of secretion of total protein to the jejunal lumen was 100 mg protein per hour per 10 cm jejunum. About 45% was due to immunoglobulins...

    Full Text Available A vertex v ∈ V (G is said to distinguish two vertices x, y ∈ V (G of a graph G if the distance from v to x is di erent from the distance from v to y. A set W ⊆ V (G is a total resolving set for a graph G if for every pair of vertices x, y ∈ V (G, there exists some vertex w ∈ W − {x, y} which distinguishes x and y, while W is a weak total resolving set if for every x ∈ V (G−W and y ∈ W, there exists some w ∈ W −{y} which distinguishes x and y. A weak total resolving set of minimum cardinality is called a weak total metric basis of G and its cardinality the weak total metric dimension of G. Our main contributions are the following ones: (a Graphs with small and large weak total metric bases are characterised. (b We explore the (tight relation to independent 2-domination. (c We introduce a new graph parameter, called weak total adjacency dimension and present results that are analogous to those presented for weak total dimension. (d For trees, we derive a characterisation of the weak total (adjacency metric dimension. Also, exact figures for our parameters are presented for (generalised fans and wheels. (e We show that for Cartesian product graphs, the weak total (adjacency metric dimension is usually pretty small. (f The weak total (adjacency dimension is studied for lexicographic products of graphs.

    A cross-over study of two oral contraceptive formulations, containing 30 micrograms ethinylestradiol in combination with 150 micrograms desogestrel (Marvelon) or 75 micrograms gestodene (Femovan), has been performed to compare the serum distribution and pharmacokinetics of gestodene and the active metabolite of desogestrel, namely 3-ketodesogestrel. Serum concentrations of both sex hormone-binding globulin (SHBG) and corticosteroid-binding globulin (CBG) were also measured and were increased more than 3-fold and 2-fold, respectively, on day 21 of the treatment cycle, with no statistically significant difference between treatment groups. In addition, 35 days after ingestion of either oral contraceptive had ceased, the serum SHBG and CBG concentrations were similar to the pretreatment values. During treatment cycles, increased serum SHBG levels were associated with a redistribution of 3-ketodesogestrel and gestodene such that the non-protein-bound (NPB) and albumin-bound fractions were reduced in concert with an increase in the relative proportions bound to SHBG. The proportion of gestodene bound to SHBG was consistently higher than that observed for 3-ketodesogestrel, and this undoubtedly reflects the higher affinity of SHBG for gestodene (Kd = 1.2 nM at 37 degrees C) when compared to 3-ketodesogestrel (Kd = 4.7 nM at 37 degrees C). It also probably accounts, in part, for the much higher total serum levels of gestodene (8.58 nmol/L) when compared to 3-ketodesogestrel (2.37 nmol/L) during the treatment cycles. Consequently, the absolute amounts of NPB, non-SHBG-bound, and SHBG-bound gestodene are significantly higher than those measured for 3-ketodesogestrel. It is concluded that ethinylestradiol-induced increases in serum SHBG levels during treatment with Marvelon or Femovan, influenced the distribution and total amount of 3-ketodesogestrel and gestodene in serum, respectively, and that this, combined with the higher affinity of SHBG for gestodene, results in a

    Adiponectin has insulin-sensitizing, anti-atherogenic, and anti-inflammatory properties, and researchers have recently reported that omega-3 polyunsaturated fatty acid (PUFA) can increase the serum adiponectin concentration, suggesting that dietary factors, such as fish intake, may have an influence on the serum adiponectin concentration. In general, Japanese subjects consume twice as much fish as people in other countries. We hypothesized that incremental change in serum omega-3 PUFA levels by fish intake is an important regulator of serum adiponectin even in Japanese subjects. The aim of this study was to explore the relationship among fish consumption, serum omega-3 PUFA, such as eicosapentaenoic acid (EPA), levels, and serum adiponectin levels. We recruited 17 healthy Japanese volunteers (seven men and 10 women) for an 8-week fish-diet intervention (omega-3 PUFA 3.0 g/day) without affecting total energy intake, and measured serum adiponectin concentration and fatty acid profiles. Fish-diet intervention significantly increased the serum adiponectin concentration in women (from 13.5+/-4.6 to 15.8+/-5.2 microg/mL, p diet intervention (57.3+/-86.6 vs 150.9+/-46.7 microg/mL, p=0.011), suggesting that changes in omega-3 PUFA concentration may explain the different response between sexes. A fish-based diet intervention increased the serum adiponectin concentration in young, non-obese, healthy Japanese female subjects. The increment in serum omega-3 PUFA may regulate the serum adiponectin concentration.

    Full Text Available This study was performed to determine the correlation between serum magnesium (Mg and dyslipidemia in patients on maintenance hemodialysis (MHD. This hospital-based cross-sectional observational study was conducted at the Department of Nephro-Urology, Liaquat University Hospital, Hyderabad, Pakistan, from April 2008 to June 2008. Fifty patients with end-stage kidney disease on MHD treatment (33 males and 17 females were studied. The mean duration on HD was 7.58 ± 2.05 years, with frequency being two to three sessions/week, and each session lasted for four hours. After obtaining informed written consent, the general information of each patient was recorded on a proforma. After overnight fasting, blood samples was drawn from the arterio-venous fistula for lipid profile, lipoprotein, serum Mg, serum creatinine, blood urea, serum calcium and serum phosphorus. Dyslipidemia was defined as presence of total cholesterol (TC, triglyceride (TG or low-density lipoprotein (LDL levels more then 95 th percentile for age and gender or high-density lipoprotein (HDL levels less then 35 mg/dL. Descriptive and inferential statistical analyses were performed using SPSS version 16.0. The mean age of the study patients was 45.68 ± 13.97 years. There was a significant positive correlation between serum Mg and serum lipoprotein-a (LP-a (r = 0.40, P < 0.007, serum HDL (r = 0.31, P < 0.01 and serum TG (r = 0.35, P < 0.005. There was no significant correlation between serum Mg and serum LDL-c and serum TC. The serum TG and LP-a levels were significantly increased while HDL-c was significantly lower in MHD patients. The serum TC, LDL-c and very low-density lipoprotein-c were not significantly elevated. We conclude that patients with chronic kidney disease undergoing MHD show positive correlation between serum Mg and serum HDL, LP-a and TG. The abnormalities of lipid metabolism, such as hyper-triglyceridemia, elevated LP-a and low HDL-c, could contribute to

    Leptin, a hormone from adipose tissue, regulates feeding behavior, satiation rate, energy expenditure and also plays an important role in maturation and reproduction. Recent studies support the concept that several factors such as a diet may influence on leptin levels. The aim of this study was to investigate serum concentration of leptin and lipids status in prepubertal children aged from 2 to 10 years with two different nutritional habits: vegetarian (n = 24) and omnivorous diet (n = 20). Serum leptin concentration was determined by immunoenzymeassay (ELISA). Serum lipids (cholesterol, HDL- and LDL-cholesterol, triglyceride) were measured by enzymatic and apolipoproteins by immunoturbidimetric methods. We noticed that in vegetarian diet there is a high rate of fiber (nearly twice as high as in omnivorous diet) and polyunsaturated acids (35% as much). In our study vegetarian children had lower total cholesterol and cholesterol in fractions HDL and LDL than meat eaters did. Also the apolipoproteins levels in vegetarian children were significantly below that of nonvegetarians. There is no differences in triglyceride concentration between the two groups of children. The mean serum leptin level in vegetarian children was significantly lower (3.1 +/- 1.2 ng/mL) as compared with the omnivores (5.6 +/- 2.1 ng/mL) (p < 0.0001).

    Objective: Iron deficiency is a common complication in patients with polycythemia vera (PV). Hepcidin is a principal regulator of iron homeostasis. The aim of our study was to assess prohepcidin, a hepcidin precursor, and other iron status pa-rameters in the serum of PV patients. Methods: The study was performed in 60 patients (F/M 26/34) aged 38~84 (66±10) years. The control group consisted of 20 healthy volunteers, age and sex matched. The following parameters were determined in blood serum samples: prohepcidin concentration, iron content, unsaturated iron binding capacity (UIBC), total iron binding capacity (TIBC), transferrin saturation (TfS), and concentrations of ferritin and soluble transferrin receptor (sTIR). Results: All PV patients showed significantly lower levels of prohepcidin, higher levels of sTIR and TIBC compared to the control group. 40% of the patients from the study group showed concentrations of ferritin below the normal range and significantly lower levels of serum iron and TfS, and significantly higher levels of sTfR, UIBC and TIBC in comparison with t
