    Full Text Available Con el objeto de establecer un rango de referencia para diferentes metabolitos en hembras bovinas B. indicus, se tomaron 5-10 mL de suero sanguíneo a 21 hembras bovinas Brahman registradas en el departamento de Caldas, Colombia. Se determinó la concentración de los diferentes metabolitos que forman parte de un perfil metabólico estándar, como beta-hidroxibutirato, proteína total, albúmina, globulinas, urea, aspartato aminotransferasa (AST, calcio y magnesio. Los resultados fueron analizados mediante la obtención del rango, promedio y desviación estándar (DE. El intervalo de referencia se estableció en el 95% (x±2DE. El promedio y la DE obtenidos para cada metabolito fueron: beta-hidroxibutirato 0,34±0,15 mmol/L; proteína total 81±9 g/L; albúmina 41±3 g/L; globulinas 40±10 g/L; urea 3,31±1,43 mmol/L; AST 158±34 U/L; Ca 2,50±0,21 mmol/L y Mg 1,40±0,44 mmol/L. Se observó que las alteraciones más frecuentes fueron aumento en la concentración de butiratos y globulinas y aumento en la actividad de AST. Según los resultados obtenidos, se puede señalar que los valores encontrados para la concentración de diferentes metabolitos séricos en hembras Brahman mantenidas en pastoreo, son similares a los valores descritos para bovinos B. taurus.This study was designed in order to get the reference values for the concentration of different metabolites included in a standard metabolic profile for grazing Brahman cattle (B. indicus from Caldas, Colombia. Serum samples (5-10 mL were taken from 21 healthy grazing Brahman cows to analyse beta-hydroxybutyrate, total protein, albumin, globulines, urea, aspartate aminotransferase (AST, calcium and magnesium. The results were analyzed by calculating range, mean and standard deviation (SD. The reference interval was set at 95% (x±2SD. The mean and SD obtained for the concentration of the different metabolites were: beta-hydroxybutyrate 0.34±0.15 mmol/L; total protein 81±9 g/L; albumin 41±3

    The influence of temperament on the alteration of metabolic parameters in response to a lipopolysaccharide(LPS) challenge was investigated. Brahman bulls were selected based on temperament score. Bulls (10 months; 211±5kg BW; n = 6, 8 and 7 for Calm, Intermediate and Temperamental groups, respectively) were fitted with indwelling jugular catheters to evaluate peripheral blood concentrations of glucose, blood urea nitrogen (BUN),non-esterified fatty acids (NEFA), insulin, epinephrine and cortisol before and after LPS administration (0.5 μg/kg BW LPS). Feed intake was also recorded. Intermediate bulls consumed more feed than the Temperamental bulls during the challenge (p = 0.046). Pre-LPS glucose (p = 0.401) and BUN (p = 0.222) did not differ among the temperament groups. However, pre-LPS insulin (p = 0.023) was lower, whereas pre-LPS NEFA (p metabolic responses of Brahman bulls following a provocative endotoxin challenge.Specifically, Temperamental bulls may preferentially utilize an alternate energy source (i.e. NEFA) to a greater degree than do bulls of Calm and Intermediate temperaments. The use of circulating NEFA from lipolysis may reduce the negative metabolic consequences of an immune response by allowing for a prompt answer to increasing energy demands required during immunological challenge, compared with the time required for glycogenolysis and gluconeogenesis.

Se seleccionaron vacas Brahman registradas, agrupadas en fértiles (15 y subfértiles (15 según historial reproductivo. Se tomaron muestras de suero y líquido folicular (diámetro >8 mm para determinar colesterol, lipoproteínas, triacilgliceroles y glucosa. Las vacas subfértiles mostraron un fenotipo masculino, con medidas corporales mayores, y concentraciones de colesterol y HDL séricos y foliculares más bajas que las vacas fértiles. El colesterol y el HDL se correlacionaron positivamente entre los compartimientos en ambos grupos. La subfertilidad es más probable en vacas pesadas con hombros amplios y mayor perímetro torácico. El tamaño corporal en vacas Brahman subfértiles se relacionó con su apariencia, con cambios en los metabolitos séricos y foliculares y con las concentraciones de colesterol y HDL.The objective of this study was to evaluate differences in body size among Brahman cows, grouped according to their fertility, to establish differences in concentrations of cholesterol, lipoproteins, and glucose, in serum and follicular fluid, and to develop a model to predict subfertility in Brahman cows using body measurements as predictors. Registered Brahman cows were selected and grouped in fertile (15 and subfertile (15 animals, according to their calving interval. Samples of blood serum and liquid from follicles (diameter >8 mm were collected in order to determine cholesterol, lipoproteins, triacylglycerols, and glucose. Subfertile cows had a masculine phenotype, their body measurements were larger than those in fertile cows, and they had lower cholesterol and HDL concentrations in

    This study characterized physiological responses to repeated transportation (TRANS) of gestating cows of differing temperaments. Cows were classified as Calm (C; = 10), Intermediate (I; = 28), or Temperamental (T; = 10). Based on artificial insemination date and pregnancy confirmation, cows were TRANS for 2 h on d 60 (TRANS1), 80 (TRANS2), 100 (TRANS3), 120 (TRANS4), and 140 (TRANS5) ± 5 d of gestation. Indwelling vaginal temperature (VT) monitoring devices were inserted 24 h before each TRANS with VT recorded from 2 h before TRANS and averaged into 5-min intervals through 30 min after TRANS. Serum samples were collected before loading and on unloading from the trailer to determine concentrations of cortisol, glucose, and nonesterified fatty acids (NEFA). Data were analyzed by repeated measures analysis in SAS. Serum cortisol concentrations were affected by temperament ( 0.10) with repeated TRANS events. Serum glucose concentrations were affected ( seasonal changes, and learning from repeated handling and transport, repeated transport is a useful model of repeated stress in studying the effects of temperament.

Serum uric acid levels were significantly higher in subjects with than without metabolic syndrome (p metabolic syndrome components (p for trend uric acid significantly correlated with various anthropometric and serum metabolic parameters. Serum uric acid levels were higher in individuals with rather than without metabolic syndrome and raised gradually as the number of metabolic syndrome components increased. The relationship between serum uric acid levels and various metabolic parameters suggests that uric acid might be considered as a component of metabolic syndrome. Hyperuricemia is a common finding in patients with the metabolic syndrome. Recent studies indicated that hyperuricemia may be also a predictor of metabolic syndrome development.

    Previously, we determined that a primary cause of proportional stunted growth in a line of Brahman cattle was related to an apparent refractoriness in metabolic response to GH in young animals. The objective of this study was to determine the effect of administration of GH, insulin (INS), and GH plus INS to mature miniature Brahman cows (n = 6; 9.7 ± 2.06 y; 391 ± 48.6 kg) and bulls (n = 8; 9.4 ± 2.00 y; 441 ± 54.0 kg) on circulating concentrations of metabolic hormones and metabolites, primarily IGF-I and IGF-I binding proteins. We hypothesized that IGF-I secretion could be enhanced by concomitant administration of exogenous GH and INS, and neither alone would be effective. Animals were allotted to a modified crossover design that included four treatments: control (CON), GH, INS, and GH + INS. At the start of the study, one-half of the cattle were administered GH (Posilac; 14-d slow release) and the other one-half served as CON for 7 d. Beginning on day 8, and for 7 d, INS (Novolin L) was administered (0.125 IU/kg BW) twice daily (7:00 AM and 7:00 PM) to all animals; hence, the INS and GH + INS treatments. Cattle were rested for 14 d and then were switched to the reciprocal crossover treatments. Blood samples were collected at 12-hour intervals during the study. Compared with CON, GH treatment increased (P cattle, suggesting that this line of Brahman cattle is capable of responding to bioactive GH. Copyright © 2011 Elsevier Inc. All rights reserved.

    The Adversary & Interdiction Methods (AIM) program provides training and capability assessment services to government agencies around the country. Interdisciplinary teams equipped with gear and radioactive sources are repeatedly fielded to offsite events to collaborate with law enforcement agencies at all levels of government. AIM has grown rapidly over the past three years. A knowledge management system as evolved along with the program but it has failed to keep pace. A new system is needed. The new system must comply with cybersecurity and information technology solutions already in place at an institutional level. The offsite nature of AIM activities must also be accommodated. Cost and schedule preclude the commissioning of new software and the procurement of expensive hardware. The new system must exploit in-house capabilities and be established quickly. A novel system is proposed. This solution centers on a recently introduced institutional file sharing capability called Syncplicity. AIM-authored software will be combined with a dedicated institutional account to vastly extend the capability of this resource. The new knowledge management system will reduce error and increase efficiency through automation and be accessible offsite via mobile devices.

    Calcium is essential to homeostasis and functioning of multiple organ systems. Its circulating concentration is maintained within a very tight physiologic range: 2.25 and 2.50 mmol/L. Under physiological conditions, the ionized calcium concentration is regulated by the parathyroid hormone (PTH), and 1,25(OH)(2) vitamin D through interactions on target organs such as kidney, bone and intestine. In mild, moderate, and severe hypercalcemia, laboratory findings are essential in assessing and monitoring disease course and therapy. The main tools are specific standard biochemical tests able to assess calcium balance and renal function, and some specific biochemical tests, such as PTH, 25(OH) vitamin D, and genetic sequencing, used to clarify the cause of hypercalcemia and, subsequently, to determine appropriate therapy. Once hypercalcemia is confirmed by ionized calcium measurement, the intact PTH assay plays a crucial role to differentiate PTH-mediated from non-PTH-mediated hypercalcemia. Mild hypercalcemia is also present in up to 10-20% of patients treated with lithium for bipolar disorders, in 7-8% of those treated with thiazide diuretics, and in patients with prolonged immobilization, while very high (>3.5 mmol/L) serum calcium levels, together with low PTH, and a rapid increase of hypercalcemia, usually suggest a malignancy-associated hypercalcemic syndrome. The measurement of PTH-related protein, a tumor product that mimics certain action of PTH, is useful only in selected cases. The role of biochemical markers of bone turnover for predicting metastatic bone disease, and monitoring bone metabolic changes, and their usefulness as a predictive mean of the likelihood of bone loss or fractures risk is still unclear.

    Serum uric acid levels have been reported to be associated with a variety of cardiovascular conditions. However, the direct association between uric acid levels and metabolic syndrome remains controversial. Thus, we evaluated the association of serum uric acid levels and metabolic syndrome in a community-based cohort study in Korea. We performed cross-sectional analysis of baseline data of 889 males and 1491 females (aged 38 to 87) who participated in baseline examinations of the Korean Genome and Epidemiology Study: Kanghwa study. Blood samples were collected after at least an 8 hour fast. Uric acid quartiles were defined as follows: Metabolic syndrome was defined by the National Cholesterol Education Program Adult Treatment Panel III Criteria with adjusted waist circumference cutoffs (90 cm for males; 80 cm for females). The association between serum uric acid quartiles and metabolic syndrome was assessed using multivariate logistic regression. The odds ratio for having metabolic syndrome in the highest versus lowest quartiles of serum uric acid levels was 2.67 (95% confidence interval [CI], 1.60 to 4.46) in males and 2.14 (95% CI, 1.50 to 3.05) in females after adjusting for age, smoking, alcohol intake, body mass index, total cholesterol, HbA1c, albumin, γ-glutamyltransferase, blood urea nitrogen, and log C-reactive protein. The number of metabolic abnormalities also increased gradually with increasing serum uric acid levels (adjusted p for trend uric acid levels are positively associated with the presence of metabolic syndrome in Korean males and females.

    A positive association between serum uric acid and metabolic syndrome has been reported, but little information is available about the association between serum uric acid and metabolic syndrome in Taiwanese adults. The purpose of this study was to investigate the association between serum uric acid levels and metabolic syndrome in Taiwanese adults. We performed a cross-sectional study of 2085 men and 1557 women. All of the participants underwent a health screening during the period from January 2005 to December 2005 at a health center of the Shin Kong Wu Ho-Su Memorial Hospital. Metabolic syndrome was defined according to the National Cholesterol Education Program Adult Treatment Panel III criteria. The results showed that hyperuricemia was significantly associated with increased risk for hypertriglyceridemia, low high-density lipoprotein cholesterol level, and high blood pressure in men and women. The risk of metabolic syndrome was significantly higher in the fourth quartile than in the first quartile of uric acid level in men (odds ratio [OR], 1.50; 95% confidence interval [CI], 1.06-2.14) and women (OR, 2.33; 95% CI, 1.39-3.93). In addition, uric acid level was inversely associated with hyperglycemia in men. The ORs of hyperglycemia for the second, third, and fourth quartile of uric acid were 0.69 (95% CI, 0.46-1.03), 0.55 (95% CI, 0.37-0.83), and 0.45 (95% CI, 0.29-0.69), respectively, compared with the lowest quartile of uric acid. The results demonstrate that there is a positive association between serum uric acid levels and metabolic syndrome and an inverse association between uric acid and fasting plasma glucose in Taiwanese adults.

    Full Text Available Background. Despite extensive research and an improved standard of care, sepsis remains a disorder with a high mortality rate. Sepsis is accompanied by severe metabolic alterations. Methods. We evaluated 117 patients with sepsis (severe sepsis [n=19] and septic shock [n=98] who were admitted to the intensive care unit. Serum cholesterol, triglyceride (TG, high-density lipoprotein (HDL, low-density lipoprotein (LDL, free fatty acid (FFA, and apolipoprotein (Apo A-I levels were measured on days 0, 1, 3, and 7. Results. Nonsurvivors had low levels of cholesterol, TG, HDL, LDL, and Apo A-I on days 0, 1, 3, and 7. In a linear mixed model analysis, the variations in TG, LDL, FFA, and Apo A-I levels over time differed significantly between the groups (p=0.043, p=0.020, p=0.005, and p=0.015, resp.. According to multivariate analysis, TG levels and SOFA scores were associated with mortality on days 0 and 1 (p=0.018 and p=0.008, resp.. Conclusions. Our study illustrated that TG levels are associated with mortality in patients with sepsis. This may be attributable to alterations in serum lipid metabolism during sepsis, thus modulating the host response to inflammation in critically ill patients.

    Full Text Available Purpose: The metabolic syndrome (MetS is a constellation of interrelated risk factors of metabolic origin that appear to promote development of cardiovascular disease. It has become one of the most important topics for this decade because of marked increase in cardiovascular disease associated with risk factors. Paraoxonase (PON is a family of three enzymes, PON1, PON2 and PON3, the gene which is located on chromosome 7. This is high-density lipoprotein (HDL-associated enzyme with antioxidant activity. The objective of the present study aimed at measurement of PON1 activities in patients with MetS, to compare PON1 activities in patients with MetS with those in controls and assess its relationship with the lipoproteins in serum. Material and Method: Cases were included as per the criteria put forth by the International Diabetes Federation. Serum PON1 activities were measured using spectrophotometer. Statistical analysis was done using SPSS 20.0. Result: Serum PON1 arylesterase and lactonase activities were found to be reduced significantly in patients with MetS than in controls. PON1 activities showed a positive correlation with HDL, fasting blood glucose and diastolic blood pressure. Linear regression analysis showed a significant correlation between PON1 activities and body mass index. Discussion: From the present study, it is clear that reduction in PON1 activities in MetS is mainly due either to abnormalities with synthesis or secretion of HDL cholesterol or oxidative stress as a consequence of excess production of the free radicals. This study also iterates that it is the quality and not the quantity of HDL cholesterol is important while studying the pathophysiology of MetS.

    We developed a serum metabolomic method by gas chromatography-mass spectrometry (GC-MS) to evaluate the effect of alprazolam in rats. The GC-MS with HP-5MS (0.25 μm × 30 m × 0.25 mm) mass was conducted in electron impact ionization (EI) mode with electron energy of 70 eV, and full-scan mode with m/z 50-550. The rats were randomly divided to four groups, three alprazolam-treated groups and a control group. The alprazolam-treated rats were given 5, 10 or 20 mg/kg (low, medium, high) of alprazolam by intragastric administration each day for 14 days. The serum samples were corrected on the seventh and fourteenth days for metabolomic study. The blood was collected for biochemical tests. Then liver and brain were rapidly isolated and immersed for pathological study. Compared with the control group, on the seventh and fourteen days, the levels of d-glucose, 9,12-octadecadienoic acid, butanoic acid, l-proline, d-mannose and malic acid had changed, indicating that alprazolam induced energy metabolism, fatty acid metabolism and amino acid metabolism perturbations in rats. There was no significant difference for alanine aminotransferase, aspartate aminotransferase, alkaline phosphatase, urea and uric acid between controls and alprazolam groups. According to the pathological results, alprazolam is not hepatotoxic. Metabolomics could distinguish different alprazolam doses in rats. Copyright © 2017 John Wiley & Sons, Ltd.

    Serum uric acid levels is reported to be associated with a variety of cardiometabolic risk factors; however, its direct association with metabolic syndrome (MetS) remains controversial. Thus, we examined the association of serum uric acid concentrations with the MetS components. MetS was defined according to the National Cholesterol Education Program (NCEP) criteria. This case-control study comprised 101 non-smoking individuals (41 in the MetS group and 60 in the non-MetS group). Blood pressure, fasting plasma glucose, insulin, HOMA-IR, lipid profiles, uric acid, and anthropometric measures were determined, and body composition was assessed by using bioelectrical impedance analysis (BIA). After adjustment for confounding factors, serum uric acid was significantly higher in MetS group than non-MetS group (5.70 ± 1.62 vs 4.97 ± 1.30 mg/dL, respectively, P = 0.001). After controlling for age, sex and body mass index in partial correlation analysis, uric acid was positively correlated with triglycerides, and negatively with HDL-C. In multiple logistic regression analysis, every 1 mg/dl elevation in the serum uric acid level increased the risk of MetS approximately by 2-folds (OR: 2.11, 95 % CI: 1.30-3.41). This study showed that those individuals with MetS have higher uric acid levels; the association of uric acid and MetS components supports that it might be an additional components of MetS.

    2011-12-01

    Full Text Available Background The use of bovine in vitro embryo production (IVP increases the reproductive potential of genetically superior cows, enabling a larger scale of embryo production when compared with other biotechnologies. However, deleterious effects such as abnormal fetal growth, longer gestation period, increased birth weight, abortion, preterm birth and higher rates of neonatal mortality have been attributed to IVP. The aim of this study was to compare the influence of in vitro embryo production and artificial insemination (AI on gestation length, complications with birth, birth weight, method of feeding colostrum, passive transfer of immunity, morbidity-mortality, and performance in Brahman calves. Results Whilst gestation length and birth weight were significantly increased in IVP-derived calves, no difference in weaning weight was observed between groups. The passive transfer of immunity (PT, was assessed in IVP (n = 80 and AI (n = 20 groups 24 hours after birth by determination of gamma-glutamyl transferase (GGT and gammaglobulin activity as well as by quantification of the concentration of total protein in serum. No differences in passive transfer or incidences of dystocia and diseases at weaning were observed between groups. Birth weight, method of feeding colostrum and dystocia were not correlated with PT in either group. Conclusions In this study, in vitro embryo production did not affect the health status, development, or passive transfer of immunity in Brahman calves.

    The relation between serum uric acid and metabolic syndrome is observed not only with frank hyperuricemia but also with serum uric acid levels within the normal range. The current "normal" range set for hyperuricemia often fails to identify patients with potential metabolic disorders. We investigate the association between serum uric acid within the normal range and incident metabolic syndrome risk, and further to determine the optimal cut-off value of serum uric acid for the diagnosis or prediction of metabolic syndrome. A total of 7399 Chinese adults (2957 men and 4442 women; ≥20 years) free of metabolic syndrome were followed for 3 years. During the 3-year follow-up, 1190 normouricemic individuals developed metabolic syndrome (16.1%). After adjusting the associated variables, the top quartile of serum uric acid levels was associated with higher metabolic syndrome development compared with the bottom quartile in men (hazard ratio (HR), 1.29; puric acid to identify metabolic syndrome were 6.3 mg/dl in men and 4.9 mg/dl in women. Our results suggested that high baseline serum uric acid levels within the normal range predict future development of metabolic syndrome after 3 y of follow-up.

    Interrelationships among growth, endocrine, immune, and temperament variables were assessed in neonatal Brahman calves. The velocity upon exiting a working chute (exit velocity) of an animal was measured and used as an objective indicator of temperament to classify calves as calm, intermediate, or temperamental. Calves (n = 116) were weighed weekly between d 0 and 21 to 24, and blood samples were collected for plasma and serum on d 0, 1, 2, 7, 14, and 21 to 24 after birth to measure concentrations of immunoglobulins, cortisol, and epinephrine (EPI). Body weight increased from d 0 through d 21 to 24 (P cortisol were greatest on d 0 before declining (P stress hormones measured (cortisol and EPI), only cortisol was associated with the early performance of the calf. Calf BW at d 21 to 24 and BW gain were positively associated with serum immunoglobulin concentrations, yet negatively associated with concentrations of cortisol. Serum immunoglobulin concentrations were negatively correlated with cortisol concentrations (r = -0.28; P = 0.003), yet positively associated with EPI concentrations (r = 0.51; P = 0.003). During the neonatal period in this study, there was no relationship of temperament with passive immunity or stress hormone concentrations; however, growth was positively associated with passive immunity and negatively associated with stress hormones. Measuring exit velocity as early in life as d 21 to 24 fails to accurately predict temperament at weaning in over 40% of Brahman calves. Our conclusion is that measurement of exit velocity should be done nearer to the time of weaning than to birth. These data can be beneficial in developing best management practices for young calves.

    Uric acid is the end product of purine metabolism in humans, and increased serum uric acid concentrations lead to gout. The objective of the current study was to identify factors that are independently associated with serum uric acid concentrations in a cohort of Czech control individuals. The cohort consisted of 589 healthy subjects aged 18-65 years. We studied the associations between the serum uric acid concentration and the following: (i) demographic, anthropometric and other variables previously reported to be associated with serum uric acid concentrations; (ii) the presence of metabolic syndrome and the levels of metabolic syndrome components; and (iii) selected genetic variants of the MTHFR (c.665C>T, c.1286A>C), SLC2A9 (c.844G>A, c.881G>A) and ABCG2 genes (c.421C>A). A backward model selection procedure was used to build two multiple linear regression models; in the second model, the number of metabolic syndrome criteria that were met replaced the metabolic syndrome-related variables. The models had coefficients of determination of 0.59 and 0.53. The serum uric acid concentration strongly correlated with conventional determinants including male sex, and with metabolic syndrome-related variables. In the simplified second model, the serum uric acid concentration positively correlated with the number of metabolic syndrome criteria that were met, and this model retained the explanatory power of the first model. Moderate wine drinking did not increase serum uric acid concentrations, and the urate transporter ABCG2, unlike MTHFR, was a genetic determinant of serum uric acid concentrations. Metabolic syndrome, moderate wine drinking and the c.421C>A variant in the ABCG gene are independently associated with the serum uric acid concentration. Our model indicates that uric acid should be clinically monitored in persons with metabolic syndrome.

    Increasing evidence suggests that serum CA 19-9 is associated with abnormal glucose metabolism. However, data on the association between CA 19-9 and metabolic syndrome is limited. The aim of the present study was to investigate the association between serum CA 19-9 and metabolic syndrome. A cross-sectional study was conducted on 3641 participants aged ≥40 years from the Songnan Community, Baoshan District in Shanghai, China. Logistic regression analysis was used to evaluate the association between serum CA 19-9 and metabolic syndrome. Multivariate logistic regression analysis showed that compared with participants in the first tertile of serum CA 19-9, those in the second and third tertiles had increased odds ratios (OR) for prevalent metabolic syndrome (multivariate adjusted OR 1.46 [95% confidence interval {CI} 1.11-1.92] and 1.51 [95% CI 1.14-1.98]; P trend  = 0.005). In addition, participants with elevated serum CA 19-9 (≥37 U/mL) had an increased risk of prevalent metabolic syndrome compared with those with serum CA 19-9 metabolic syndrome. In order to confirm this association and identify potential mechanisms, prospective cohort and mechanic studies should be performed. © 2017 Ruijin Hospital, Shanghai Jiaotong University School of Medicine and John Wiley & Sons Australia, Ltd.

    Hyperleptinemia and metabolic acidosis (MA) are frequently observed in patients on hemodialysis (HD). While the role of leptin in patients on HD is not completely understood, HD only partially corrects MA. Both leptin and acidosis have effect on bone disease. The goal of the present study was to evaluate the effects of MA correction on chronic kidney disease-mineral and bone disorder laboratory parameters and leptin levels. Forty-eight patients on HD, aged 43±19 years, were prospectively studied. Individual adjustments in the bicarbonate dialysate concentration were made to maintain pre-dialysis concentration≥22 mEq/l. Blood gas analysis was done monthly for 4 months (M1-M4). From M0 to M4, serum albumin increased (from 3.5 ±0.3 to 4.0±0.3 g/l, pleptin decreased in all but three patients, as well as leptin/adiponectin ratio (pleptin, an atherogenic marker. The impact of such treatment extends to uremic bone disease, as decrease in serum calcium and increase in PTH. However, this could be an undesirable effect because it may aggravate a secondary hyperparathyroidism. Whether the reduction in leptin levels has impact on outcomes in patients on hemodialysis deserves further investigation.

    Comparisons involving Brahman and Brahman-derivative (Brangus, Santa Gertrudis, Beef-master, Simbrah, Braford) sires indicate the following: 1) cows mated to Brangus and Santa Gertrudis bulls had a shorter gestation length than cows mated to Brahman bulls, 2) calves sired by Brangus and Beefmaster bulls were lighter at birth and weaning than calves sired by Brahman bulls, and 3) birth and weaning weights were similar for calves sired by Santa Gertrudis and Brahman bulls and for calves sired by Simbrah and Brahman bulls. Comparisons involving Brahman and other Zebu (Sahiwal, Nellore, Gir, Indu-Brazil, Boran, Romana Red) sires indicate that gestation length was slightly longer for cows mated to Sahiwal and Nellore bulls and that, relative to the Brahman, birth and weaning weights were similar to or lighter for calves sired by bulls of the other Zebu breeds. The only exception to this pattern was birth weight of Indu-Brazil-sired calves, which were heavier than calves sired by Brahman bulls. Comparisons involving Brahman and non-Zebu subtropically adapted (Tuli, Senepol) sires indicate that cows mated to Tuli bulls had a slightly shorter gestation length than cows mated to Brahman bulls and that birth and weaning weights of calves sired by Tuli and Senepol bulls were lighter than those of calves sired by Brahman bulls.

    Metabolic syndrome is closely linked to obesity. Menopause may play a critical role in understanding the pathophysiology of metabolic syndrome in women. We investigated the relative contribution of obesity and menopause to the association between serum adiponectin levels and the development of metabolic syndrome. A prospective cohort study was conducted in which a total of 1,219 women without metabolic syndrome were examined at baseline (2005-2008) and followed up (2008-2011). Women were divided according to tertiles of serum adiponectin levels and menopause status, and then stratified into four groups: the nonobese with high adiponectin; the nonobese with low adiponectin; the obese with high adiponectin; and the obese with low adiponectin. During an average 2.5-year follow-up, 44 premenopausal women (9.8%) and 161 postmenopausal women (20.9%) developed metabolic syndrome. The obese group with low serum adiponectin demonstrated an increased risk for developing metabolic syndrome in both premenopausal (odds ratio [OR] 5.92, 95% confidence interval [CI] 2.24-15.66) and postmenopausal women (OR 4.22, 95% CI 2.41-7.36). However, the inverse association between serum adiponectin levels and incidence of metabolic syndrome was observed in premenopausal women with obesity (OR 0.16, 95% CI 0.03-0.81), but not in postmenopausal women with obesity (OR 0.55, 95% CI 0.27-1.14). High serum adiponectin levels showed no inverse association with metabolic syndrome in postmenopausal women with obesity. These findings may suggest a need for closer management of metabolic risk in postmenopausal women.

    The objective was to determine whether serum uric acid concentrations were associated with metabolic syndrome in a population from Wuhan. 5,628 subjects (2,838 men, 2,790 women) aged 18-80 years were recruited in Wuhan, China. Biochemical parameters of venous blood were measured by standard methods and metabolic syndrome was defined by Chinese Diabetes Society criteria. Association analysis was performed by logistic regression. 8.2% of the included subjects were confirmed as having metabolic syndrome and 14.4% were confirmed as having hyperuricemia. After multivariable adjustment, logistic regression showed the odds ratios of metabolic syndrome for subjects in the highest quartile of serum uric acid concentration was 2.84 (95% CI: 2.09-3.86) compared with those in the lowest quartile and no gender difference was found. For each component of metabolic syndrome, subjects in the highest quartile of serum uric acid concentrations had increased multivariable odds ratios for high BMI (OR: 3.29, 95% CI: 2.71-3.98), for hypertension (OR: 3.54, 95% CI: 2.93-3.86), for dyslipidemia (OR: 2.49, 95% CI: 1.98-3.14), but not for hyperglycemia (OR: 1.21, 95% CI: 0.87-1.67). Odd ratio of metabolic syndrome was significantly positively associated with serum uric acid concentration among the present sample of 5,628 subjects in Wuhan.

    The present study was conducted to compare the serum ferritin status between the postmenopausal vegetarians and non-vegetarians and to identify the relation of serum ferritin with metabolic syndrome (MetS) risk factors in postmenopausal women. The two study groups consisted of postmenopausal vegetarians (n=59) who maintained a vegetarian diet for over 20 years and age-matched non-vegetarian controls (n=48). Anthropometric measurements, dietary intakes, serum metabolic syndrome-related parameters, and serum ferritin level between the two groups were compared. The vegetarians exhibited significantly lower weight (pvegetarians (33.9 %) than in non-vegetarians (47.9 %). Vegetarians had significantly lower serum level of ferritin (pvegetarians. In the correlation analysis, serum ferritin was positively related to fasting glucose (r=0.264, pvegetarians had lower MetS presence and a lower serum ferritin level compared to non-vegetarians. Furthermore, vegetarians' low serum ferritin level may reduce the risk of MetS in postmenopausal women.

    Metabolic syndrome increases the risk of mortality. Increased oxidative stress and inflammation may play an important role in the high mortality of individuals with metabolic syndrome. Previous studies have suggested that lycopene intake might be related to the reduced oxidative stress and decreased inflammation. Using data from the National Health and Nutrition Examination Survey, we examined the hypothesis that lycopene is associated with mortality among individuals with metabolic syndrome. A total of 2499 participants 20 years and older with metabolic syndrome were divided into 3 groups based on their serum concentration of lycopene using the tertile rank method. The National Health and Nutrition Examination Survey from years 2001 to 2006 was linked to the mortality file for mortality follow-up data through December 31, 2011, to determine the mortality rate and hazard ratios (HR) for the 3 serum lycopene concentration groups. The mean survival time was significantly higher in the group with the highest serum lycopene concentration (120.6 months; 95% confidence interval [CI], 118.8-122.3) and the medium group (116.3 months; 95% CI, 115.2-117.4), compared with the group with lowest serum lycopene concentration (107.4 months; 95% CI, 106.5-108.3). After adjusting for possible confounding factors, participants in the highest (HR, 0.61; P = .0113) and in the second highest (HR, 0.67; P = .0497) serum lycopene concentration groups showed significantly lower HRs of mortality when compared with participants in the lower serum lycopene concentration. The data suggest that higher serum lycopene concentration has a significant association with the reduced risk of mortality among individuals with metabolic syndrome. Copyright © 2016 Elsevier Inc.

    Tartrate-resistant phosphatase isoform 5a is expressed in tumor-associated macrophages and is a biomarker of chronic inflammation. Herein, we correlated serum tartrate-resistant phosphatase isoform 5a levels with metabolic syndrome status and made comparisons with traditional markers of inflammation, including c-reactive protein and interleukin-6. One hundred healthy volunteers were randomly selected, and cut-off points for metabolic syndrome related inflammatory biomarkers were determined using receiver operating characteristic curves. Linear and logistic regression models were subsequently used to correlate inflammatory markers with the risk of metabolic syndrome. Twenty-two participants met the criteria for metabolic syndrome, and serum tartrate-resistant phosphatase isoform 5a levels of >5.8 μg/L were associated with metabolic syndrome (c-statistics, 0.730; p = 0.001; 95% confidence interval, 0.618-0.842). In addition, 1 μg/L increases in tartrate-resistant phosphatase isoform 5a levels were indicative of a 1.860 fold increase in the risk of metabolic syndrome (p = 0.012). Elevated serum tartrate-resistant phosphatase isoform 5a levels are associated with the risk of metabolic syndrome, with a cut-off level of 5.8 μg/L.

    Regular and continuous yoga exercise is one of the most important nonpharmacological methods of improving serum lipid concentrations, adipose tissue, and metabolic syndrome factors. The purpose of this study was to analyze the effects of yoga exercise on serum adiponectin and metabolic syndrome factors in obese postmenopausal Korean women. Sixteen healthy postmenopausal women aged 54.50 ± 2.75 years with more than 36% body fat were randomly assigned to either a yoga exercise group (n = 8) or to a "no exercise" control group (n = 8). The variables of body composition, visceral fat, serum adiponectin, and metabolic syndrome factors were measured in all the participants before and after the 16-week study. Body weight, percentage of body fat, lean body mass, body mass index, waist circumference, and visceral fat area had significantly decreased. High-density lipoprotein cholesterol and adiponectin had significantly increased, but total cholesterol, triglyceride, low-density lipoprotein cholesterol, blood pressure, insulin, glucose, and homoeostasis model assessment-insulin resistance had significantly decreased. Serum adiponectin concentrations were significantly correlated with waist circumference, high-density lipoprotein cholesterol, diastolic blood pressure, and homoeostasis model assessment-insulin resistance in the postyoga exercise group. Our findings indicate that yoga exercise improves adiponectin level, serum lipids, and metabolic syndrome risk factors in obese postmenopausal women. Consequently, yoga exercise will be effective in preventing cardiovascular disease caused by obesity in obese postmenopausal Korean women.

The aim of this study was to investigate the association between hyperferritinemia and iron consumption. Methods and Results. Serum ferritin concentration was evaluated in 66 presumed healthy men, along with other clinical and biochemical markers of chronic diseases. A three-day food questionnaire was applied for nutrition information. Hyperferritinemia was a condition found in 13.4% of the volunteers analyzed. Significant correlations were found between serum ferritin concentration and metabolic syndrome parameters (HDL cholesterol, triglycerides, and fasting glucose as well as an increase of the serum ferritin mean value with the number of risk factors of metabolic syndrome. Also, oxidative stress markers (carbonyl groups, AOPP, and glycated hemoglobin, hepatic damage markers (GGT, SGOT, and parameters related to insulin resistance (HOMA, blood insulin, and blood glucose correlate significantly with serum ferritin. Volunteers had an excessive iron intake, principally by bread consumption. Analyses of food intake showed that red meat consumption correlates significantly with serum ferritin. Conclusion. Red meat consumption, metabolic syndrome, and chronic disease markers are associated with hyperferritinemia in a population of Chilean men.

    Data about the association between serum uric acid and metabolic syndrome in healthy adolescents are sparse. This study examined this association and determined the optimal cutoffs for serum uric acid to predict metabolic syndrome among healthy adolescents. During 2010-2011, we conducted a cross-sectional study of 927 adolescents (53.0% boys) aged 11-16 years from junior and senior high schools in northeast China. All participants received a physical examination and gave venous blood samples. Serum uric acid was positively associated with abdominal obesity, dyslipidemia and hypertension in boys and with abdominal obesity and dyslipidemia in girls. For those with hyperurecemia, the odds ratios (95% CI) for metabolic syndrome were 7.67 (95% CI, 2.58~22.78) for boys and 4.77 (95% CI, 1.01~22.60) for girls. SUA was a better predictor of metabolic syndrome than fasting glucose, though not as good as waist circumference. Among adolescents in China, serum uric acid level may be a useful predictor of metabolic syndrome.

    It is definite that the serum iron level has a positive correlation with the risk of obesity. However, the association between increased serum ferritin levels and the metabolic syndrome still remains controversial. The purpose of this meta-analysis is to confirm the association between serum ferritin levels and metabolic syndrome. We searched PubMed and the China National Knowledge Infrastructure (CNKI) for relevant articles that assessed the association between serum ferritin levels and metabolic syndrome and were published between 2006 and 2014. Review Manage 5.3 software was used to collect and analysis the data cited in the ultimately selected papers. The variance was exhibited using the forest plot and the heterogeneity among studies was examined using the I(2) index. We use the funnel plot to evaluate the publication bias. Cross-sectional study, case-control study and prospective cohort study met our inclusion criteria including data from a total of 4,797 participants. The pooled odds ratio (OR) for the metabolic syndrome comparing the highest and lowest category of ferritin levels was 1.20 (95% CI: 0.69, 1.71; I(2)=96%). The meta-analysis demonstrates that elevated ferritin levels are positive aassociated with metabolic syndrome.

    A blood pre-centrifugation delay of 24 h at room temperature influenced the proton NMR spectroscopic profiles of human serum. A blood pre-centrifugation delay of 24 h at 4 Degree-Sign C did not influence the spectroscopic profile as compared with 4 h delays at either room temperature or 4 Degree-Sign C. Five or ten serum freeze-thaw cycles also influenced the proton NMR spectroscopic profiles. Certain common in vitro preanalytical variations occurring in biobanks may impact the metabolic profile of human serum.

    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.

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

    Calving and weaning data from crossbred calves sired by five Bos indicus breeds and one Bos taurus breed were evaluated. Data included calving and weaning records of F1 calves out of multiparous Hereford cows and sired by Angus, Gray Brahman, Gir, Indu-Brazil, Nellore, and Red Brahman bulls. At calving, Angus-sired calves had shorter gestations and lower (more desirable) calving ease scores and were smaller than Bos indicus-sired calves. Among the Bos indicus crosses, Gir calves had the shortest gestations, lowest calving ease scores, lightest birth weights (P less than .05), and smallest cannon bone lengths and heart girths. Nellore calves had the longest gestations (P less than .05) and largest heart girths. Calves by Indu-Brazil sires had the highest calving ease scores, highest birth weights (P less than .05), and greatest cannon bone lengths (P less than .05). Gray Brahman- and Red Brahman-sired calves were similar and intermediate for all calving characters. At weaning, Angus-sired calves had gained slightly faster than the Gir crosses and weighed more but were shorter at the hip than Gir crosses. Gir calves gained the least preweaning, weighed the least, and were shortest at weaning of the Bos indicus crosses. The Nellore and Indu-Brazil crosses were intermediate in preweaning gain and weaning weight to the Gir and the Red and Gray Brahman but were tallest at weaning. Gray Brahman and Red Brahman calves gained the most and were heaviest at weaning but were not as tall as the Nellore and Indu-Brazil.

    Full Text Available Objective: To evaluate the relationship between the serum resistin levels and metabolic syndrome (MetS in chronic spontaneous urticaria (CSU patients. Methods: In the study 42 CSU patients and 42 healthy volunteers were included. Height, weight, waist circumference, and blood pressure measurements were assesed for both of the groups. Fasting blood sugar, serum lipid levels, resistin and tumor necrosis factor-alpha (TNF-α levels were evaluated in the venous blood samples. The metabolic syndrome (MetS diagnosis was determined using the National Cholesterol Education Program Adult Treatment Panel III diagnostic criteria. Results: MetS was found in 14 (33.3% CSU patients and 5 (11.9% control subjects. There was a statistically significant difference between the two groups (p=0.037 in terms of MetS presence. It was found that the mean serum resistin levels was 1928.31±212.85 pg/mL in the CSU patients and 2107.60±156.71 pg/mL in the control group. There was no statistically significant difference between the groups in terms of serum resistin levels. No difference was seen between the patients with and without a diagnosis of MetS regarding the urticaria activity score, duration of the disease, autologous serum skin test positivity, serum immunoglobulin E levels, presence of autoimmunity, serum resistin and TNF-α levels. Conclusion: An increased incidence of MetS in the CSU patient group is found in our study. However, there was no difference between the CSU patients with and without MetS regarding the disorder-associated parameters and the serum resistin and TNF-α levels.

    Elevated serum uric acid levels and increased arginase activity are risk factors for cardiovascular diseases (CVD). The aim of the present study was to investigate effects of serum uric acid levels on the arginase pathway in women with metabolic syndrome (MetS). Serum arginase activity, and nitrite and uric acid levels were measured in 48 women with MetS and in 20 healthy controls. The correlation of these parameters with components of MetS was also evaluated. Our data show statistically higher arginase activity and uric acid levels but lower nitrite levels in women with MetS compared to controls. Serum uric acid levels were negatively correlated with HDL cholesterol, nitrite levels and positively with Body Mass Index, waist to hip ratio, triglyceride and total cholesterol levels, systolic blood pressure, Homeostasis Model Assessment-Insulin Resistance-Index, serum arginase activity, and LDL-cholesterol levels in women with MetS. Results of the present study suggest that serum uric acid levels may contribute to the pathogenesis of MetS through a process mediated by arginase pathway, and serum arginase activity and nitrite and uric acid levels can be used as indicators of CVD in women with MetS.

    Several components of metabolic syndrome (MetS) facilitate its diagnosis, including abdominal obesity, hyperlipidemia, high blood pressure, and insulin resistance. The production of interleukin-6 (IL-6) and tumor necrosis factor-alpha (TNF-α) seem to be associated with MetS components. The aim of this study was to evaluate the correlation between IL-6 and TNF-α serum levels with MetS and its components. This case-control study investigated 250 subjects, comprising 125 healthy controls from the Kerman Blood Transfusion Organization and 125 MetS patients. Serum IL-6 and TNF-α levels were measured using the enzyme-linked immunosorbent assay (ELISA). Serum IL-6 and TNF-α levels were greater in MetS patients than in controls. However, no correlation was observed between MetS components and IL-6 or TNF-α serum levels. Patients with MetS had significantly greater serum IL-6 and TNF-α levels than the controls, supporting the evidence that inflammation plays an important role in the immunopathogenesis of the disease. Additionally, IL-6 and TNF-α serum levels may predict MetS. The lack of association between IL-6 and TNF-α serum levels and MetS components remains to be investigated by further research.

    Full Text Available BACKGROUND Metabolic syndrome is an important risk factor for cardiovascular disease and type 2 diabetes mellitus. According to International Diabetes Federation, the risk factor associated with metabolic syndrome are central obesity, hypertension, increased fasting glucose, triglyceride level and decreased HDL. Recent studies also found that hyperuricaemia is also associated with insulin resistance and increased cardiovascular disease related morbidity. A cross-sectional study was conducted at Pondicherry Institute of Medical Sciences with an objective to find the prevalence of hyperuricaemia among patients with metabolic syndrome and also to find the association of risk factor of metabolic syndrome with serum uric acid level. MATERIALS AND METHODS 103 patients (49 males and 54 females who fulfilled the inclusion criteria were included in the study. Detailed medical history and physical examination including height, weight, BMI, waist circumference and blood pressure were recorded. Five millilitre of fasting blood sample was taken for lipid profile, serum uric acid and fasting blood glucose. Chi-square test was done to find out the association between metabolic syndrome and risk factors of hyperuricaemia with ‘p’ value of 0.05. Exercise had negative influence on uric acid level in both gender, 41% less in males and 14% less in females. Diet also had positive influence on uric acid levels in both male and female. CONCLUSION The prevalence of hyperuricaemia among males is higher than females. The risk factors of metabolic syndrome like obesity, hypertension and increased cholesterol level are associated with hyperuricaemia.

    Comparisons were made among F1 steers sired by Brahman and alternative subtropically adapted breeds of bulls for feedlot and carcass traits when steers were produced from Angus- and Hereford-type dams. Brahman-derivative breeds included Brangus, Beefmaster, and Santa Gertrudis. Brangus- and Beefmaster-sired steers weighed less at slaughter, whereas carcasses of Brangus- and Santa Gertrudis-sired steers had more marbling than those of Brahman-sired steers. Brahman-sired steer carcasses had greater longissimus muscle area than carcasses of Santa Gertrudis-sired steers. Other Zebu breeds compared to Brahman were Boran, Gir, Indu-Brazil, Nellore, Red Brahman, and Sahiwal. Steers by Brahman sires had higher slaughter weights than steers by Boran, Gir, Nellore, or Sahiwal sires. Hot carcass weights of Brahman-sired steers were also higher than those of Boran- and Sahiwal-sired steers. Steer carcasses by Brahman sires had greater longissimus muscle area than those of steers by Sahiwal sires. Non-Zebu breeds included Tuli and Senepol. Steers by Tuli sires grew slower, had lower slaughter weights, and their carcasses weighed less than those of Brahman-sired steers. Brahman-sired steer carcasses had greater longissimus muscle area but less marbling than carcasses of Tuli-sired steers. These data suggest that steers by Brahman sires have an advantage for slaughter weight over steers by Brangus, Beefmaster, Boran, Gir, Nellore, Sahiwal, and Tuli sires, but their carcasses are at a disadvantage for marbling score compared with those by Brangus, Boran, Nellore, and Tuli sires.

    Full Text Available I contrast briefly the Buddhist concept of Self as a process and a conditional reality with the concept of the substantial metaphysical concept of Self in Brahmanism and Hinduism. I present the criticism of the Buddhist thinkers, such as Nāgārjuna, who criticize any idea of the metaphysical Self. They deny the idea of the Self as its own being or as a possessor of its mental acts. However, they do not reject all sense of Self; they allow a pure process of knowledge (first of all, Self-knowledge without a fixed subject or “owner” of knowledge. This idea is in a deep accord with some Chan stories and paradoxes of the Self and knowledge.

    Full Text Available Background: The metabolic syndrome is seen as a  cluster of high cardiovascular risk factors. New hormone-like substances, such as adipokines leptin and apelin, produced by fat tissue, are important for the pathophysiology of the metabolic syndrome.Aim: To evaluate levels of plasma apelin and serum leptin in patients with metabolic syndrome.Materials and methods: We examined 122 male patients with metabolic syndrome and 30 healthy males aged from 25 to 60 years. All patients were assessed accordingly to confirm the diagnosis of the metabolic syndrome, with additional measurements of serum leptin and plasma apelin.Results: Serum leptin levels were 10-fold higher and plasma apelin levels 3-fold higher in patients with metabolic syndrome (n=122, compared to the controls (n=30: 25.43 vs. 3.99 ng/mL (p<0.05 and 1.13 vs. 0.66 ng/mL (p<0.05, respectively. Serum leptin levels correlated with all parameters of the excess body weight, such as body mass (r=0.79, р<0.05, body mass index (r=0.93, р<0.05, waist circumference (r=0.61, р<0.05, hip circumference (r=0.57, р<0.05, and waist-to-hip ratio (WHR; r=0.4, р<0.05. Plasma apelin levels correlated with the waist circumference (r=0.27, р<0.05 and WHR (r=0.29, р<0.05. There was a significant increase of serum leptin dependent on the bodyweight category: 19.8 ng/mL in patients with obesity Grade I  (n=49 and 28.7  ng/mL in those with obesity Grade II (n=46 (р<0.05. There was a  non-significant trend towards an increase in plasma apelin depending on bodyweight. As far as abdominal obesity is concerned, in patients with WHR<1 (n=35, plasma apelin level was 0.36  ng/mL, whereas in those with WHR of ≥1 (n=87, it was 3-fold higher (1.09 ng/mL, р<0.05; the increase in serum leptin levels was non-significant. There was no association between plasma apelin and serum leptin in patients with metabolic syndrome (r=0.1, р>0.05.Conclusion: The adipokine levels in men with metabolic syndrome are

    Evidence of the relationship between serum vitamin D levels and cardiovascular risk factors in children is limited. We investigated the associations between serum vitamin D levels (25-hydroxyvitamin D [25(OH)D]) and obesity and metabolic syndrome and its components in Korean children. We recruited 1660, nine-year-old, Korean children (904 boys and 756 girls) who voluntarily participated in this study while being examined during school-based health examinations. We measured anthropometric variables (height and weight), metabolic parameters (blood pressure, fasting plasma glucose, triglyceride, and HDL cholesterol levels) and serum vitamin D levels. We analyzed the data using multivariate logistic regression models. Mean 25(OH)D levels were lower in children defined as obese or abdominally obese (P children from the highest quartile of 25(OH)D levels as a referent, the adjusted ORs (95% CI) for obesity in those in the third, second, and lowest quartiles of 25(OH)D levels were 1.55 (1.01-2.40), 1.87 (1.22-2.85), and 2.59 (1.71-3.90), respectively (P for trend obesity the ORs (CI) were 2.08 (1.20-3.60), 2.32 (1.36-3.95), and 2.96 (1.75-5.00) (P for trendmetabolic syndrome they were 2.60 (1.08-6.30), 4.00 (1.73-9.26), and 4.25 (1.84-9.85), respectively (P for trend children to be associated with obesity and metabolic syndrome.

    Expression profiling using microarrays allows for the detailed characterization of the gene networks that regulate an animal's response to environmental stresses. During nutritional restriction, processes such as protein turnover, connective tissue remodeling, and muscle atrophy take place in the skeletal muscle of the animal. These processes and their regulation are of interest in the context of managing livestock for optimal production efficiency and product quality. Here we expand on recent research applying complementary DNA (cDNA) microarray technology to the study of the effect of nutritional restriction on bovine skeletal muscle. Using a custom cDNA microarray of 9,274 probes from cattle muscle and s.c. fat libraries, we examined the differential gene expression profile of the LM from 10 Brahman steers under three different dietary treatments. The statistical approach was based on mixed-model ANOVA and model-based clustering of the BLUP solutions for the gene x diet interaction effect. From the results, we defined a transcript profile of 156 differentially expressed array elements between the weight loss and weight gain diet substrates. After sequence and annotation analyses, the 57 upregulated elements represented 29 unique genes, and the 99 downregulated elements represented 28 unique genes. Most of these co-regulated genes cluster into groups with distinct biological function related to protein turnover and cytoskeletal metabolism and contribute to our mechanistic understanding of the processes associated with remodeling of muscle tissue in response to nutritional stress.

    Intracellular levels of cyclic nucleotides, such as cGMP, are involved in the regulation of adipocyte lipolysis. Cumulus-oocyte complexes (COCs) express enzymes that both synthesise (guanylate cyclase) and degrade (phosphodiesterase (PDE) 5A) cGMP. Because serum interferes with lipid metabolism, its effects on the cGMP pathway and lipid content in bovine COCs were examined. COCs were matured in medium containing fetal calf serum (FCS; 2% or 10%) or 0.4% bovine serum albumin (BSA; control). At both 2% and 10%, FCS decreased cGMP levels in COCs compared with BSA (0.64 and 1.04 vs 9.46 fmol per COC respectively; P0.05). In addition, lipid content was higher in embryos from oocytes matured with FCS than BSA (fluorescence intensity 31.12 vs 22.31 respectively; Pbovine COCs and that this pathway is affected by FCS.

    Full Text Available Background Stochastic resonance therapy (SRT is used for rehabilitation of patients with various neuropsychiatric diseases. An alteration in tryptophan metabolism along the kynurenine pathway has been identified in the central and peripheral nervous systems in patients with neuroinflammatory and neurodegenerative diseases and during the aging process. This study investigated the effect of SRT as an exercise activity on serum tryptophan metabolites in healthy subjects. Methods Serum L-tryptophan, L-kynurenine, kynurenic acid, and anthranilic acid levels were measured one minute before SRT and at one, 5, 15, 30, and 60 minutes after SRT. We found that SRT affected tryptophan metabolism. Serum levels of L-tryptophan, L-kynurenine, and kynurenic acid were significantly reduced for up to 60 minutes after SRT. Anthranilic acid levels were characterized by a moderate, non significant transient decrease for up to 15 minutes, followed by normalization at 60 minutes. Tryptophan metabolite ratios were moderately altered, suggesting activation of metabolism after SRT. Lowering of tryptophan would generally involve activation of tryptophan catabolism and neurotransmitter, protein, and bone biosynthesis. Lowering of kynurenic acid by SRT might be relevant for improving symptoms in patients with neuropsychiatric disorders, such as Parkinson's disease, Alzheimer's disease, schizophrenia, and depression, as well as certain pain conditions.

    The association between thyroid hormones within the euthyroid range and metabolic syndrome is not clear. This study evaluated the relationship between thyroid hormones and metabolic syndrome and its components in euthyroid subjects. This is a cross-sectional population based study conducted within the framework of the cohort of the Tehran Thyroid Study. Out of 5786 subjects aged ≥ 20 years, 3755 euthyroid subjects without a history of thyroid disorders, diabetes, or use of steroids or lipid-lowering agents were investigated. Body weight, waist circumference (WC), and blood pressure (BP) were measured. Serum concentrations of lipids and lipoproteins, fasting blood glucose (FBG), insulin, free T4 (FT4), and thyrotropin (TSH) were assayed. Metabolic syndrome was determined by definition of the Joint Interim Statement adjusted for the Iranian population. After adjustment for age, sex, and smoking, serum FT4 was significantly associated with high-density lipoprotein cholesterol (HDL-C), low-density lipoprotein cholesterol (LDL-C), triglycerides (TGs), WC, systolic BP, and diastolic BP; the associations that remained significant after further adjustment for body mass index (BMI) and the homeostasis model assessment index for insulin resistance (HOMA-IR) except for HDL-C. Serum TSH was associated only with TGs after adjustments for age, sex, smoking, and BMI, an association that disappeared after further adjustment for HOMA-IR. Serum FT4 was negatively associated (β=-0.02, 95% confidence interval [CI: -0.03, -0.01]) and TSH was positively associated (β = 0.03 [CI: 0.01, 0.04) with insulin resistance. The prevalence of metabolic syndrome decreased from 30.1% in the lowest FT4 tertile to 22.4% in the highest FT4 tertile (p<0.001). The prevalence of other metabolic syndrome components decreased significantly from higher to lower FT4 tertiles. Higher FT4 values were associated with lower odds of metabolic syndrome (OR = 0.96 [95% CI: 0.92, 0.99]; p=0.01). In euthyroid

    Full Text Available Aim: This study was conducted to understand whether serum level of the steroid and metabolic hormones may be indicative of their level in ovarian follicular fluid (FF in porcine, and its influence on fertility. Materials and Methods: Ovaries from pigs (n=32 of two genetic groups, namely, native (Ghungroo; n=16 and crossbred (Hampshire × Ghungroo; n=16 were collected. Both the genetic groups comprised gilts (n=8 and sows (n=8, and sows were in luteal phase of estrus cycle. FF was aspirated from small, medium and large follicles, and centrifuged for the collection of supernatant for further analysis. Blood samples were collected from the same animals, and serum was separated. Hormones, namely, cortisol, T3, T4 and testosterone were estimated by radioimmunoassay. Two-way ANOVA was used for analysis of data considering genetic background (native or crossbred, stage of reproductive life (gilt or sow, and source of sample (serum or FF as fixed effects. Results: It was observed that all the hormones except cortisol differed significantly (p<0.01 based on genetic background. Stage of reproductive life and source of sample did not affect the studied hormonal level. Within the genetic groups, stage of reproductive life influenced T3 (p<0.01, cortisol (p<0.05 and testosterone (p<0.01 level in crossbred pigs as compared to T3 (p<0.01 only in native pigs. The level of T3 in serum, as well as FF, was higher (p<0.01 in Ghungroo gilts compared to sows. However, a reverse of this was observed in the case of crossbred pigs. The level of cortisol (p<0.05 and testosterone (p<0.01 was higher in crossbred sows than gilts in both serum and FF. Conclusion: The study revealed that serum level of the steroid and metabolic hormones is indicative of their level in the ovarian FF. Further, varying level of steroid and metabolic hormones in pigs based on genetic background may be due to variation in body size, rate of energy metabolism and stage of (reproductive life.

    To determine whether elevations of uric acid levels are associated with the cluster of disorders described in metabolic syndrome and to evaluate whether hyperuricemia may be considered a component of this syndrome. One year case-control study was conducted in Bikaner, Rajasthan, India from January to December 2013. The study population consisted of 200 subjects, 100 with metabolic syndrome (case) and 100 without metabolic syndrome (control) aged between 18 and 80 years, attending OPD at PBM Hospital were studied. Controls were age and sex matched to the cases. Blood tests and all physical variables were examined using standard methods. Subjects were divided into 6 groups according to their possession of 0, 1, 2, 3, 4 or 5 components of the metabolic syndrome. Statistical analysis was done using ANOVA, linear regression analysis and multivariate linear regression model. Mean serum UA level was significantly associated with all components of metabolic syndrome (pmetabolic factors increased showing a highly significant trend (pmetabolic syndrome. The current multivariate regression analysis clearly infers that uric acid can be considered as a marker and potential modifier of metabolic syndrome. Copyright © 2016 Diabetes India.

    Chronic kidney disease (CKD) is one of the major complications of hypertension. It is not only associated with the future burden of end-stage renal disease but also affects mortality and cardiovascular outcomes caused by hypertension. To help understand the pathogenesis and early prevention of progressive CKD, this large-scale study is designed to determine the complex association between serum uric acid (SUA), metabolic syndrome and the prevalence of CKD in hypertensive patients. A total of 19,848 hypertensive subjects were enrolled in this cross-sectional study. Patients with proteinuria and/or an estimated glomerular filtration rate (eGFR) of metabolic syndrome, as well as higher levels of SUA, BMI, waist circumference (WC), SBP, DBP, TG, fasting blood glucose and lower levels of HDL-C. Compared to patients without CKD, the multivariate-adjusted odds ratios [ORs, 95% confidence interval (CI)] for CKD patients were 2.30 (2.02-2.63) for hyperuricemia, 1.21 (1.04-1.41) for abdominal obesity, 1.21 (1.06-1.38) for elevated TG, 1.29 (1.06-1.56) for low HDL-C, 1.54 (1.36-1.75) for elevated fasting glucose, and 1.49 (1.30-1.71) for metabolic syndrome. Increasing SUA levels and number of individual metabolic syndrome components were associated with an increased prevalence of CKD. Compared with patients classified in the lowest SUA categories and with ≤1 metabolic syndrome components, subjects with HUA and 4 metabolic syndrome components had a 5.77-fold increased OR for CKD based on the multivariate-adjusted analysis. Both elevated SUA and metabolic syndrome are associated with an increased prevalence of CKD in hypertensive subjects. Subjects with higher SUA and sum of individual metabolic syndrome components simultaneously have a higher prevalence of CKD. © 2016 The Author(s) Published by S. Karger AG, Basel.

    Obesity is one of the diagnostic criteria of metabolic syndrome (MS). It is correlated with insulin resistance (IR) and high vascular risk as well. Advanced glycation end products (AGEs) and their receptor (RAGE) play an important role in abnormal metabolic components in obese women. This study aimed to explore the serum levels of sRAGE in Egyptian obese women and compare with healthy non-obese controls and investigate the relationship between serum sRAGE, metabolic parameters, and obesity complications. The soluble form of receptor for advanced glycation end products (sRAGE), anthropometry, metabolic and biochemical biomarkers were measured in 100 obese women and 100 age-matched healthy control non-obese women. The homeostasis model assessment estimate of insulin resistance (HOMA-IR) has been determined from serum insulin and glucose values. Serum sRAGE levels were significantly lower in obese cases than controls and inversely correlated with obesity and metabolic parameters. Results of univariate and multivariate analyses for determinants of serum sRAGE levels in obese cases showed that parameters statistically and significantly related were body mass index (BMI), waist circumference (WC), LDL-C, TG, BP, HOMA-IR, ALT and AST. sRAGE is a novel biomarker for metabolic dysfunction in Egyptian obese women and might predict the future cardio-metabolic events.

    To determine the presence of a relationship between metabolic presbycusis and serum paraoxonase/arylesterase activity. A total of 30 patients who had been admitted to the Ear, Nose, and Throat (ENT) Clinic of Fırat University Medical Faculty and diagnosed as metabolic presbycusis were included in the study. The control group was composed of 30 healthy volunteers. Pure tone audiometry and impedencemeter were performed on all subjects included in the study at the audiometry laboratory of the ENT clinic. The presence of a regular hearing curve, a symmetrical sensorineural hearing loss more than 25 dB with preserved speech discrimination were accepted as criteria for metabolic presbycusis. Blood samples were drawn from the patients prior to the hearing tests. The sera were separated for measurements of total cholesterol, triglyceride, high-density lipoprotein, very low-density lipoprotein, low-density lipoprotein, human serum paraoxonase and arylesterase levels, respectively. No statistically significant difference was found between the patient and the control groups in terms of age and gender. Paraoxonase, arylesterase and paraoxonase/arylesterase, high-density lipoprotein levels were found to decrease in the study group and the difference was found to be statistically significant compared to the control group (P presbycusis. Furthermore, the results of this study make us think that there could be a relationship between metabolic presbycusis and cardiovascular diseases. In this case, metabolic presbycusis may be a determining parameter in the early diagnosis of cardiovascular diseases. We consider that this study may be the pioneer for further studies conducted with larger patient numbers.

    Potentially significant associations between metabolic syndrome (MetS) and periodontal disease have been reported in recent studies; however, there is a dearth of literature regarding the relationship of MetS with serum antibody levels to periodontal pathogens. The aim of this cross-sectional study was to investigate the association between MetS and serum antibody to the periodontal pathogen Porphyromonas gingivalis (P. gingivalis) in 216 Japanese individuals aged 79 years. Serum antibody levels to P. gingivalis were measured by enzyme-linked immunosorbent assay. An elevated serum antibody response was defined as the upper quartile and was considered as the outcome variable. A multivariable logistic regression model was used to evaluate the association of MetS defined by the modified National Cholesterol Education Program Adult Treatment Panel III criteria with an elevated antibody status. Adjustments for gender, income, education, smoking status, dental-care utilisation patterns and brushing frequency were considered. The prevalence of MetS was 22.2% (n = 48). Study participants with MetS were 2.9 times more likely to have an elevated serum antibody to P. gingivalis (adjusted odds ratio = 2.91, 95% confidence interval = 1.24-6.85) after simultaneous adjustment for other covariates. Our findings suggest an independent relationship between MetS and serum antibody levels to P. gingivalis in the Japanese elderly. Additional longitudinal epidemiologic studies with larger, more diversified samples and more complete information are needed to substantiate our findings. © 2014 John Wiley & Sons A/S and The Gerodontology Association.

    Full Text Available Metabolic profiling in liver and serum of mice was studied for the combined toxic effects of deoxynivalenol (DON and zearalenone (ZEN, through gas chromatography mass spectrum. The spectrum of serum and liver sample of mice, treated with individual 2 mg/kg DON, 20 mg/kg ZEN, and the combined DON + ZEN with final concentration 2 mg/kg DON and 20 mg/kg ZEN for 21 days, were deconvoluted, aligned and identified with MS DIAL. The data matrix was processed with univariate analysis and multivariate analysis for selection of metabolites with variable importance for the projection (VIP > 1, t-test p value < 0.05. The metabolic pathway analysis was performed with MetaMapp and drawn by CytoScape. Results show that the combined DON and ZEN treatment has an obvious “antagonistic effect” in serum and liver tissue metabolic profiling of mice. The blood biochemical indexes, like alkaline phosphatase, alanine transaminase, and albumin (ALB/globulin (GLO, reveal a moderated trend in the combined DON + ZEN treatment group, which is consistent with histopathological examination. The metabolic pathway analysis demonstrated that the combined DON and ZEN treatment could down-regulate the valine, leucine and isoleucine biosynthesis, glycine, serine and threonine metabolism, and O-glycosyl compounds related glucose metabolism in liver tissue. The metabolic profiling in serum confirmed the finding that the combined DON and ZEN treatment has an “antagonistic effect” on liver metabolism of mice.

    The influence of additive and nonadditive genetic effects and temperament on 4 postweaning feed intake and growth traits was evaluated in a group of 581 bull, heifer, and steer calves born in 3 Florida herds in 2006 and 2007. Calves had breed compositions ranging from 100% Angus (A) to 100% Brahman (B). They were randomly allocated to 24 pens each year by herd (Brooksville, Gainesville, Marianna, FL), sire group (A, 3/4 A 1/4 B, Brangus, 1/2 A 1/2 B, 1/4 A 3/4 B, and B), and sex (bull, heifer, and steer) in a GrowSafe automated feeding facility at Marianna. Calves were fed a concentrate diet during the 21-d adjustment and the 70-d trial periods. Individual feed intakes were recorded daily, and BW, chute scores, and exit velocities were recorded every 2 wk. Traits were phenotypic daily residual feed intake (RFI), mean daily feed intake (DFI), mean daily feed conversion ratio (FCR), and postweaning BW gain. Phenotypic RFI was computed as the difference between actual and expected feed intakes. Calves were assigned to 3 RFI groups: high (RFI greater than 0.9 kg of DM/d), low (RFI less than -0.9 kg of DM/d), and medium (RFI between mean +/- 0.9 kg of DM/d; SD = 1.8 kg of DM/d). The mixed model included the fixed effects of contemporary group (herd-year-pen), RFI group (except when trait was RFI), age of dam, sex of calf, age of calf, B fraction of calf, heterozygosity of calf, mean chute score, and mean exit velocity. Brahman fraction and heterozygosity of calf were nested within sex of calf for RFI and within RFI group for DFI, FCR, and postweaning BW gain. Random effects were sire and residual. Feed efficiency tended to improve (decreased RFI) as the B fraction increased. However, calves required larger amounts of feed per kilogram of BW gain (larger FCR) as the B fraction increased. Postweaning BW gain tended to decrease as the B fraction increased. Temperament traits were unimportant for all traits except exit velocity for DFI, suggesting perhaps a lack of

Data corresponding to 58257, 57045 and 40364 for BW, WW and YW, respectively, were analyzed. The models included the effects of year and season of birth and sex, and were considered simple interactions. Results. All effects were significant (p0.05 on WW. The average general BW, WW and YW were 32±3.2, 188±37.7 and 291±56.8 kg, respectively. Variables evaluated that take into account the year of birth show a trend to increase weight each year. In relation to the birth season on BW and YW, it was observed that calves born during the rainy season were heavier than those born during the dry season. Similarly, male calves were heavier than females at birth, weaning and one year of age. The effects of the analyzed interactions were significant (p0.05 for BW and WW. Conclusions. The studied non-genetic factors were important and should be taken into account in management strategies when striving to increase the efficiency of the productive system.

    Background Cell death due to anoikis, necrosis and cell egress from transplantation sites limits functional benefits of cellular cardiomyoplasty. Cell dissociation and suspension, which are a pre-requisite for most cell transplantation studies, lead to depression of cellular metabolism and anoikis, which contribute to low engraftment. Objective We tissue engineered scaffolds with the goal of rapidly restoring metabolism, promoting viability, proliferation and engraftment of encapsulated stem cells. Methods The carboxyl groups of HA were functionalized with N-hydroxysuccinimide (NHS) to yield HA succinimidyl succinate (HA-NHS) groups that react with free amine groups to form amide bonds. HA-NHS was cross-linked by serum to generate HA:Serum (HA:Ser) hydrogels. Physical properties of HA:Ser hydrogels were measured. Effect of encapsulating cardiosphere-derived cells (CDCs) in HA:Ser hydrogels on viability, proliferation, glucose uptake and metabolism was assessed in vitro. In vivo acute intra-myocardial cell retention of 18FDG-labeled CDCs encapsulated in HA:Ser hydrogels was quantified. Effect of CDC encapsulation in HA:Ser hydrogels on in vivo metabolism and engraftment at 7 days was assessed by serial, dual isotope SPECT-CT and bioluminescence imaging of CDCs expressing the Na-iodide symporter and firefly luciferase genes respectively. Effect of HA:Ser hydrogels +/− CDCs on cardiac function was assessed at 7 days & 28 days post-infarct. Results HA:Ser hydrogels are highly bio-adhesive, biodegradable, promote rapid cell adhesion, glucose uptake and restore bioenergetics of encapsulated cells within 1 h of encapsulation, both in vitro and in vivo. These metabolic scaffolds can be applied epicardially as a patch to beating hearts or injected intramyocardially. HA:Ser hydrogels markedly increase acute intramyocardial retention (~6 fold), promote in vivo viability, proliferation, engraftment of encapsulated stem cells and angiogenesis. Conclusion HA:Ser hydrogels

    Full Text Available Our objective was to evaluate the concentrations of serum 25-hydroxyvitamin D [25(OHD], serum calcium, serum phosphorus, alkaline phosphatase, and parathormone (PTH in patients with polyarticular juvenile idiopathic arthritis (JIA and to associate them with disease duration and activity, bone mineral density and use of medications. In a cross-sectional and controlled study, 30 patients with polyarticular JIA were evaluated and compared to 30 healthy individuals matched for age and gender. Clinical status, anthropometry, laboratory markers in both patients and controls, and bone mineral density, only in the patients, were measured. Of the 30 patients included in the study, 23 (76.7% were female and 16 (53.3% non-Caucasian; mean age was 14 years (range = 4 to 20 years. Mean disease duration was 5 years (range = 1 to 12 years. The mean concentrations of serum albumin-corrected calcium (9.04 ± 0.41 mg/dL and alkaline phosphatase (153.3 ± 100.1 IU were significantly lower in patients with JIA than in controls (P < 0.0001 and P = 0.001, respectively. No differences in 25(OHD, PTH or serum phosphorus were observed between JIA and control subjects. Regarding 25(OHD concentration, 8 patients (26.7% and 5 controls (16.7% had 25(OHD concentrations compatible with deficiency (lower than 20 ng/mL and 14 patients (46.7% and 18 controls (60% had concentrations compatible with insufficiency (20-32 ng/mL. These values were not associated with disease activity, use of medications or bone mineral density. We observed a high frequency of 25(OHD insufficiency and deficiency in the study sample. The compromised bone metabolism emphasizes the importance of follow-up of JIA patients.

    Serum uric acid levels have been reported to be associated with metabolic syndrome (MetS). However, few studies specifically examining the relationship between serum uric acid (SUA) levels and MetS in postmenopausal women have been reported in China. Thus, we conducted this study in order to assess the relationship between SUA levels and MetS in Chinese postmenopausal women. A cross-sectional study of 1022 Chinese postmenopausal women (aged 42-80 years) who participated in annual health check-ups was employed. MetS was defined by National Cholesterol Education Program/Adult Treatment Panel III criteria (NCEP-ATP III). Of all the participants, 385 women were diagnosed with MetS (MetS group) and the others were without MetS (non-MetS group). SUA quartiles were defined as follows: Q1, metabolic syndrome in the highest SUA quartile vs. the lowest quartile was 3.768 (2.386-5.950) for all women (p uric acid quartile (p for trend < 0.001). Higher SUA levels are positively and independently associated with the presence of MetS in Chinese postmenopausal women.

    Disuse osteopenia was studied in hibernating black bears (Ursus americanus) using serum markers of bone metabolism. Blood samples were collected from male and female, wild black bears during winter denning and active summer periods. Radioimmunoassays were done to determine serum concentrations of cortisol, the carboxy-terminal cross-linked telopeptide, and the carboxy-terminal propeptide of Type I procollagen, which are markers of hone resorption and formation, respectively. The bone resorption marker was significantly higher during winter hibernation than it was in the active summer months, but the bone formation marker was unchanged, suggesting an imbalance in bone remodeling and a net bone loss during disuse. Serum cortisol was significantly correlated with the bone resorption marker, but not with the bone formation marker. The bone formation marker was four- to fivefold higher in an adolescent and a 17-year-old bear early in the remobilization period compared with the later summer months. These findings raise the possibility that hibernating black bears may minimize bone loss during disuse by maintaining osteoblastic function and have a more efficient compensatory mechanism for recovering immobilization-induced bone loss than that of humans or other animals.

    Full Text Available Objective: To study the serum homocysteine (Hcy level in patients with acute cerebral infarction and its correlation with inflammatory factors, nerve factors and NO metabolism. Methods: A total of 118 patients with acute cerebral infarction were selected as observation group and 50 healthy volunteers who received physical examination in our hospital during the same period were selected as the normal control group. Serum levels of Hcy in two groups were detected, and the median of Hcy levels in observation group was referred to further divide them into high Hcy group and low Hcy group, 59 cases in each group. Serum contents of inflammatory factors, nerve factors and NO metabolism markers were compared between acute cerebral infarction patients with different levels of Hcy. Results: Serum Hcy level in observation group was higher than that in control group. Serum contents of inflammatory factors such as IL-1β, IL-6, IL-17 and hs-CRP in high Hcy group were higher than those in low Hcy group, contents of nerve factors such as Copeptin, NT-proBNP, NSE and S-100B in high Hcy group were higher than those in low Hcy group, and contents of NO metabolism indexes such as NO and NOS in high Hcy group were higher than those in low Hcy group. Conclusion: Serum Hcy level increases in patients with acute cerebral infarction, and the level of Hcy is directly related to inflammatory factors, nerve factors and NO metabolism.

    Serum proteins and peptides have potential as biomarkers since they form the structural and functional basis of tissues and are involved in metabolic and regulatory processes. Changes in their profiles or their breakdown products have been of interest as potential biomarkers. Tibial dyschondroplasia (TD) and femoral head separation (FHS) are two metabolic skeletal problems in poultry that cause lameness. The objective of this study was to identify serum peptide changes associated with lameness in poultry that may be predictive of the disease and may help in eliminating these hereditary defects from the genetic pool. Serum peptides were extracted from six-wk-old chickens with or without the above leg problems using C18 magnetic beads and analyzed by MALDI-TOF mass spectrometry. Differentially expressed peptides were analyzed in the m/z range of 1,000-10,000 using ClinproTool™ software. Twenty two peaks from TD and 20 from FHS affected chickens were compared with their respective controls. The spectral peaks were identified using mass spectrometry followed by a data base search. Some of the peptides identified were hemostasis associated breakdown products. No differentially expressed peptide was detected in FHS but a peptide with m/z 5308.1 was elevated in chickens with TD (p⩽0.05). It was identified as a fragment of alpha 1 type-XI isoform 1. Type XI collagen is a cartilage specific extracellular matrix protein that is involved in the organization of other collagens and maintains extracellular matrix integrity. Its breakdown product may indicate cartilage degeneration in tibial dyschondroplasia thus may serve as a surrogate marker for this problem.

    This study aimed to investigate the relationship between serum irisin level and metabolic and anthropometric parameters in obese children. The study included 36 obese children with a body mass index (BMI) of ≥95th percentile and 30 healthy children with a BMI ranging from the 5th to the 85th percentile. Healthy and obese children had similar age, gender and pubertal stage distribution. Anthropometric and biochemical parameters (fasting glucose, insulin, lipid profile, leptin and irisin levels) were measured. Bioelectric impedance analysis was used to determine the body composition parameters, including body fat percentage and fat mass. Serum irisin and leptin levels of the obese children were significantly higher than those of the healthy children [median irisin levels, 141.2 & 107.6ng/mL, p=0.024; median leptin levels, 10.9 & 2.9pg/mL, P<0.001, respectively). No statistically significant difference was found when leptin and irisin levels were compared among obese patients in terms of the presence of insulin resistance. Irisin levels significantly correlated with high-density lipoprotein cholesterol (HDL-C), fasting insulin and homeostasis model assessment-insulin resistance (HOMA-IR) with adjustment for age and BMI. The multivariate regression analysis showed that age, HOMA-IR and HDL-C had a significant association with the serum irisin level, which explained 30.6% of the variance. This study demonstrated that obese children had significantly higher irisin levels than healthy children. Additionally, it provides evidence regarding the role of irisin on insulin sensitivity and lipid metabolism in childhood obesity. Copyright © 2016 Elsevier Inc. All rights reserved.

    Although multifunctional glycoprotein α2HS-glycoprotein/human fetuin-A (AHSG) is involved in atherosclerosis, it is not clear whether high or low concentrations are more important. We studied the correlation of serum AHSG with adiponectin, leptin, resistin, C-reactive protein (CRP) and tumour necrosis factor-α (TNF-α) to see whether its metabolic effects or its involvement in subclinical inflammation are dominant in patients with established coronary disease. In this cross-sectional study, AHSG concentration was determined in sera of 171 patients (age: 62 ± 6 years, mean ± SD) with previous myocardial STEMI infarction and normal renal function and 81 age-matched healthy controls by radial immunodiffusion. Results  Patients had increased AHSG levels (673 ± 103 vs. 619 ± 96 mg L(-1), P AHSG concentration than those with normal BMI or without diabetes but even the latter group had elevated AHSG levels (667 ± 101 mg L(-1), n = 88) compared to controls (P = 0·002). Serum AHSG correlated negatively with adiponectin (r = -0·236, P = 0·006) even after adjusting for BMI (r = -0·177, P = 0·043). AHSG determined adiponectin levels independently from BMI, age and other adipocytokines (P = 0·014). The correlation between leptin and AHSG (r = 0·321, P = 0·021) weakened following adjustment for BMI (r = 0·209, P = 0·072). Serum AHSG did not correlate significantly with CRP, resistin and TNF-α concentrations. BMI and resistin but not AHSG determined TNF-α levels independently. AHSG is elevated in sera of patients with previous myocardial infarction. Association with adipokines favours the concept that AHSG is involved in atherosclerosis more likely through metabolic pathways (insulin resistance, obesity and adipocyte dysfunction) than by inflammation in patients with post-myocardial infarction. © 2011 The Authors.

    Hepcidin is an iron-regulatory peptide hormone that consists of 3 isoforms: bioactive hepcidin-25, and inactive hepcidin-22 and hepcidin-20. Hepcidin is instrumental in the diagnosis and monitoring of iron metabolism disorders, but reliable methods for its quantification in serum are sparse, as is knowledge of their relative analytical strengths and clinical utility. We developed a competitive (c)-ELISA and an immunocapture TOF mass-spectrometry (IC-TOF-MS) assay. Exploiting these 2 methods and our previously described weak cation exchange (WCX)-TOF-MS assay, we measured serum hepcidin concentrations in 186 patients with various disorders of iron metabolism and in 23 healthy controls. We found that (a) the relative differences in median hepcidin concentrations in various diseases to be similar, although the absolute concentrations measured with c-ELISA and WCX-TOF-MS differed; (b) hepcidin isoforms contributed to differences in hepcidin concentrations between methods, which were most prominent in patients with chronic kidney disease; and (c) hepcidin concentrations measured by both the c-ELISA and IC-TOF-MS correlated with ferritin concentrations <60 μg/L, and were suitable for distinguishing between iron deficiency anemia (IDA) and the combination of IDA and anemia of chronic disease. c-ELISA is the method of choice for the large-scale quantification of serum hepcidin concentrations, because of its low limit of detection, low cost, and high-throughput. Because of its specificity for bioactive hepcidin-25, WCX-TOF-MS can be regarded as a valuable special-purpose assay for disorders with variable concentrations of hepcidin isoforms, such as chronic kidney disease.

Cystatin C is a novel marker for cardiovascular disease. We aimed to investigate exercise electrocardiographic responses in patients with metabolic syndrome who were without overt diabetes mellitus, in addition to the association of serum cystatin C levels with the exercise electrocardiographic test results.Method: Forty-three consecutive patients admitted to a cardiology outpatient clinic without angina pectoris were recruited if they met criteria for metabolic syndrome but did not have overt diabetes mellitus. Serum cystatin C levels were measured, and all participants underwent exercise electrocardiographic testing. Patients who were found to have ischemia had a coronary angiography procedure.Results: The mean cystatin C level of patients was higher in metabolic syndrome group than healthy controls (610.1 ± 334.02 vs 337.3 ± 111.01 µg/L; P < 0.001. The percentage of patients with ischemia confirmed by coronary angiography was 13.9% in the metabolic syndrome group. Cystatin C levels in the ischemic patients of the metabolic syndrome group were higher than that in nonischemic patients (957.00 ± 375.6 vs 553.8 ± 295.3 µg /L; P = 0.005. Chronotropic incompetence was observed in 30.2% of the patients with metabolic syndrome compared with 16.7% in the control group (P = 0.186. Chronotropic response indices were 0.8 ± 0.18 versus 0.9 ± 0.10 for the two groups, respectively (P = 0.259. HRR was significantly lower in the metabolic syndrome patients compared with the controls (20.1 ± 8.01 vs 25.2

    Semaphorin-3E, provoking inflammation and insulin resistance which leads to metabolic syndrome, exerts obscure effects on carotid atherosclerosis in metabolic syndrome. The Tribbles 3 Q84R polymorphism is involved in insulin resistance. This study aims to investigate whether the Tribbles 3 Q84R polymorphism has profound effects on serum semaphorin 3E and what effect semaphorin 3E exerts on carotid atherosclerosis. A total of 518 unrelated Chinese subjects consisted of control (n=258) and metabolic syndrome (n=260) groups. Clinical and biochemical characteristics were collected. The level of serum semaphorin 3E was measured by enzyme-linked immunosorbent assay. Genotyping of the functional Tribbles 3 Q84R polymorphism was achieved by RFLP-PCR method. All subjects underwent carotid ultrasonography to determine carotid intima-media thickness (considered atherosclerosis if above 0.9 mm). Serum semaphorin 3E was significantly increased in metabolic syndrome (P=0.012) as compared with the control group. Among the metabolic syndrome group, those with RR84 genotype had significantly higher levels of serum semaphorin 3E than those with QQ84 or QR84 genotypes (P=0.003, P=0.004) with similarity amongst the control group. Factorial analyses showed statistically significant interactions between RR84 genotype and metabolic syndrome (P=0.019 for interaction for semaphorin 3E). Semaphorin 3E correlated positively with homeostasis model assessment insulin resistance (r=0.263, P=0.009) and carotid intima-media thickness (r=0.215, P=0.031). On partial analyses, after controlling for confounding factors, semaphorin 3E was positively correlated with carotid intima-media thickness (P=0.004). Individuals with metabolic syndrome demonstrated further increased serum semaphorin 3E, especially those with Tribbles 3 RR84 genotype. Increased serum semaphorin 3E may in part exacerbate insulin resistance and carotid atherosclerosis. © 2017 by the Association of Clinical Scientists, Inc.

    Irisin and oxytocin can affect energy homeostasis and it has been suggested that they may play an important role in reducing obesity and diabetes. In this study, we aimed to determine the relationship between metabolic parameters (including irisin and oxytocin levels) and anthropometric parameters in obese children. Ninety obese children (mean age, 13.85±1.63 years) and 30 healthy controls (mean age, 14.32±1.58 years) were enrolled in this study. Anthropometric and laboratory parameters (glucose, insulin, lipid, oxytocin, and irisin levels) were analyzed. The serum irisin and oxytocin levels were measured by enzyme-linked immunosorbent assay. Bioelectrical impedance was used to determine body composition. Irisin level was higher in the patients than in the controls (p=0.018), and this higher irisin level was correlated with increased systolic blood pressure, body mass index, waist/hip ratio, fat percentage, fat mass, glucose level, insulin level, and homeostasis model assessment of insulin resistance. Serum oxytocin level was significantly decreased in obese children compared to the controls (p=0.049). Also, among the 60 obese patients, oxytocin level was significantly lower in patients with than in those without metabolic syndrome (8.65±2.69 vs. 10.87±5.93 ng/L, respectively), while irisin levels were comparable (p=0.049 and p=0.104, respectively). There were no statistically significant relationships between oxytocin or irisin levels and lipid levels (p>0.05). Obese children had significantly higher irisin levels than the healthy controls. Additionally, this study shows for the first time that oxytocin level is significantly lower in obese compared with non-obese children and also lower in obese children with metabolic syndrome compared to those without.

    To evaluate the association between fasting duration and lipid and metabolic test results. A cross-sectional study was conducted in healthy children aged 0-6 years from The Applied Research Group for Kids! (TARGet Kids!) primary care practice network, Toronto, Canada, 2008-2013. The associations between duration of fasting at blood collection and serum lipid tests and metabolic tests were evaluated using linear regression. Among 2713 young children with blood tests the fasting time ranged from 0 to 5 hours (1st and 99th percentiles). Fasting duration was not significantly associated with total cholesterol (β = 0.006; P = .629), high-density lipoprotein (HDL) (β = 0.002; P = .708), low-density lipoprotein (β = 0.0013; P = .240), non-HDL (β = 0.004; P = .744), or triglycerides (β = -0.016; P = .084) adjusted for age, sex, body mass index, maternal ethnicity, and time of blood draw. Glucose, insulin, and homeostasis model assessment of insulin resistance were significantly associated with fasting duration, and the average percent change between 0 and 5 hours was -7.2%, -67.1%, and -69.9%, respectively. The effect of fasting on lipid or metabolic test results did not differ by age or sex; HDL and triglycerides may differ by weight status. In this cohort of healthy young children, we found little evidence to support the need for fasting prior to measurement of lipids. The effect of fasting on glucose was small and may not be clinically important. When measuring serum lipid tests in early childhood, fasting makes a very small difference.

    Endothelial dysfunction is associated with hypertension, atherosclerosis, and metabolic syndrome. Phycocyanin is a pigment found in the blue-green algae, Spirulina, which possesses antihypertensive effect. In this study, we hypothesized that phycocyanin derived from Spirulina exerts antihypertensive actions by improving endothelial dysfunction in metabolic syndrome. Spontaneously hypertensive/NIH-corpulent (SHR/NDmcr-cp) rats were divided into 4 groups then fed a normal diet with or without phycocyanin (2500-, 5000-, or 10,000-mg/kg diet) for 25 weeks. At 34 weeks of age, although systolic blood pressure was not significantly different among groups, phycocyanin-fed groups exhibited a dose-dependent decrease in blood pressure. Serum levels of adiponectin and messenger RNA levels of adiponectin and CCAAT/enhancer-binding protein α in the adipose tissue of rats fed diets containing phycocyanin tended to be higher than those of rats fed a normal diet, but the differences were not statistically significant. Immunohistochemistry analysis showed a significant and positive correlation between aortic endothelial nitric oxide synthase (eNOS) expression levels, a downstream target of the adiponectin receptor, and serum adiponectin levels, although there were no significant differences in eNOS expression among groups. There was also no significant correlation between eNOS expression levels and systolic blood pressure. These results suggest that long-term administration of phycocyanin may ameliorate systemic blood pressure by enhancing eNOS expression in aorta that is stimulated by adiponectin. Phycocyanin may be beneficial for preventing endothelial dysfunction-related diseases in metabolic syndrome. Copyright © 2013 Elsevier Inc. All rights reserved.

    The aim of the study was to assess the association of serum uric acid levels with microalbuminuria -urinary albumin excretion (UAE)> or = 30mg/24h-. Cross-sectional study in 429 (220 women) hypertensive, non diabetic, never treated patients (mean age: 47 years) with glomerular filtration rate > or =60ml/min/1.73m(2). The prevalence of microalbuminuria was 20.5%; 18% had hyperuricemia and 47% fulfilled the criteria for metabolic syndrome (MS). Baseline UAE correlated in the unvaried analysis to diastolic blood pressure, waist circumference, high-density lipoprotein cholesterol and uric acid. In multiple linear regression models, only MS (beta=0.113; p=0.03), and serum uric acid values (beta=0.04; p=0.05) were independently associated with logUAE, after adjustment for age and sex. Hyperuricemia (serum uric acid level > or =7.0mg/dl for men and > or =6.5mg/dl for women; odds ratio=2.18; 95% confidence interval, 1.21-3.92; p=0.010), and MS (odds ratio=2.16; 95% confidence interval, 1.32-3.53; p=0.002) were independently associated with a higher risk of microalbuminuria in multiple logistic regression analyses. The prevalence of microalbuminuria was 45.8% in patients with coexistent MS and hyperuricemia, as compared to 13.6% in hypertensive patients without it (p<0.001). In patients with concomitant MS and hyperuricemia the probability of being microalbuminuric was 3.7 times higher than in patients without those factors. Serum uric acid level is associated with microalbuminuria. Coexistence of MS and hyperuricemia in hypertensive patients increases almost 4 times the odds of being microalbuminuric.

    Epidemiologic studies have demonstrated that elevated serum uric acid concentration is an independent risk factor for metabolic syndrome. However, few studies have focused on elderly populations. Thus, we investigated the association of serum uric acid concentration with metabolic syndrome in community-dwelling elderly Koreans. This cross-sectional analysis included 2940 participants (986 men and 1954 women) aged 65 years or older who participated in a baseline health assessment for the Korean Urban Rural Elderly cohort study from 2012 to 2014. Serum uric acid concentration was analyzed using both continuous and dichotomous variables. Hyperuricemia was defined as a uric acid concentration ≥7.0 mg/dL in men and ≥6.0 mg/dL in women. Metabolic syndrome was defined according to the 2009 harmonizing definition. Multiple logistic regression models were used to investigate independent association between serum uric acid and metabolic syndrome, after adjusting for age, body mass index, LDL cholesterol, glycated hemoglobin, blood urea nitrogen, estimated glomerular filtration rate health behaviors, and medications. Prevalence of metabolic syndrome and its components increased significantly according to uric acid concentration in both sexes. The adjusted odds ratios for having metabolic syndrome per 1.0mg/dL higher uric acid concentration were 1.16 (95% CI: 1.03-1.31) in men and 1.27 (95% CI: 1.13-1.42) in women. Hyperuricemia was also associated with metabolic syndrome, with adjusted odds ratios of 1.71 (95% CI: 1.11-2.63) in men and 1.55 (95% CI: 1.05-2.29) in women. Elevated serum uric acid concentration was independently associated with an increased prevalence of metabolic syndrome in community-dwelling elderly Koreans. Copyright © 2016 Elsevier Ireland Ltd.

    The aim of this study is to investigate the association between serum uric acid level and metabolic syndrome according to menopausal status in Korean women. A total of 2,241 women who visited to the health promotion center at Pusan National University Hospital from 2010 to 2014 were included in this cross-sectional study. Self-report questionnaires and interviews with healthcare providers were used to assess disease history, medication history, menstrual history and body size measuring. Anthropometric measurements and laboratory results were compared as presence of metabolic syndrome and menopausal status by student-t test. Logistic regression analysis was performed between presence of metabolic syndrome and presumable predictive factors, such as age, menopause and serum uric acid. The prevalence rate of metabolic syndrome were 7.45% (63/846) in pre-menopausal group and 23.87% (333/1395) in menopausal group. Serum uric acid level was higher in menopausal women than premenopausal women (4.6 ± 1.1 vs. 4.3 ± 0.9. P = 0.000). And, its concentration was also higher in metabolic syndrome than normal women regarding of menopausal statue (premenopause 4.7 ± 1.1 vs. 4.2 ± 0.8, P = 0.001, menopause 4.9 ± 1.3 vs. 4.5 ± 1.0, P = 0.000). Multiple logistic regression analysis showed serum uric acid and age have relationship with metabolic syndrome (OR: 1.453, 95% confidence interval [CI]: 1.074-1.111, P = 0.000; OR: 1.092, 95% CI: 1.305-1.619, P = 0.000). We could find out some potential of uric acid as predictive factor for metabolic syndrome in premenopausal and menopausal group. Further investigation is required to clarify the relationship between serum uric acid, menopause and metabolic syndrome.

    to study the efficacy of Nigella sativa in central obese men on serum free testosterone, body weight, waist circumference, blood sugar, lipid, uric acid, adiponectin, hs-CRP, and side effects in the treatment group compare to control. an experimental, clinical test, double blinded with placebo control, pre-test and post-test design. Subjects are 30-45 years old, divided into the treatment and control groups, and evaluated weekly for 3 months. Data obtained were subjective complaints, body weight, waist circumference, and blood pressure, serum free testosterone, fasting blood sugar, triglyceride, HDL-Cholesterol, uric acid, creatinin, SGOT and SGPT, adiponectin, and hs-CRP. Data collected from March 2007 to June 2007 at Prof.Dr.RD Kandou General Hospital, Manado, North Sulawesi, Indonesia. Statistical analysis was performed using descriptive for subjects characteristic and drug's side effect, t independent to compare between two parametric independent variables, Mann-Whitney U to compare between two non-parametric independent variables, and Wilcoxon Signed Ranks test to compare between two non-parametric dependent variables. in the treatment group, complaints related to central obesity disappear in first week, very significant reduction of body weight, waist circumference, and systolic blood pressure, insignificant reduction in serum free testosterone, diastolic blood pressure, fasting blood sugar, triglyceride and cholesterol-HDL, uric acid, hs-CRP, and insignificant increase of adiponectin. On comparison between both groups, we found a very significant reduction on body weight and waist circumference, but the insignificant reduction on serum free testosterone, systolic and diastolic blood pressure, and the unsignificant increase of adiponectin, meanwhile the reduction of serum free testosterone in the treatment group was smaller than the control group, that means Nigella sativa could inhibit the decreasing of serum free testosterone. No side effects were detected

    The relationship between elevated serum uric acid level and metabolic syndrome (MS) has been debated. There is no data concerning this relation in Iranian population-based studies. The aim of this study was to determine the prevalence of hyperuricamia and its association with MS in type 2 diabetes mellitus (DM). This was a cross- sectional study in 1978 diabetic patients. Hyperuricamia was defined as uric acid ≥ 7 and ≥ 5.5 mg/dl for men and women respectively. Diagnosis of metabolic syndrome was based on ATPIII criteria. Clinical and biochemical parameters in hyperuricaemic and normouricaemic patients compared with other. The prevalence of hyperuricaemia and metabolic syndrome was 12.7% and 65.5% respectively. The prevalence of MS significantly increased in the highest quartile of uric acid levels compared with lowest quartile (74.4% vs 55.9%, puric acid had positive association with cholesterol, triglyceride, non-HDL cholesterol and a negative association with fasting blood sugar (FBS), glycosylated hemoglobin (HbA1C) and HDL cholesterol. Possible independent biochemical predictors of hyperuricamia were cholesterol, triglyceride, creatnine and FBS. The prevalence of MS and its components increases with increasing levels of uric acid in type 2 diabetes. Regular assessment of uric acid could give information for predicting of MS and prevention of atherosclerosis in type 2 diabetes.

    Metabolic alkalosis, which is a non-massive blood transfusion complication, is not reported in the literature although metabolic alkalosis dependent on citrate metabolism is reported to be a massive blood transfusion complication. The aim of this study was to investigate the effect of elevated carbon dioxide production due to citrate metabolism and serum electrolyte imbalance in patients who received frequent non-massive blood transfusions. Fifteen inpatients who were diagnosed with different conditions and who received frequent blood transfusions (10-30 ml/kg/day) were prospectively evaluated. Patients who had initial metabolic alkalosis (bicarbonate>26 mmol/l), who needed at least one intensive blood transfusion in one-to-three days for a period of at least 15 days, and whose total transfusion amount did not fit the massive blood transfusion definition (acidosis developed as a result of citrate metabolism. There was a positive correlation between cumulative amount of citrate and the use of fresh frozen plasma, venous blood pH, ionized calcium, serum-blood gas sodium and mortality, whereas there was a negative correlation between cumulative amount of citrate and serum calcium levels, serum phosphorus levels and amount of urine chloride. In non-massive, but frequent blood transfusions, elevated carbon dioxide production due to citrate metabolism causes intracellular acidosis. As a result of intracellular acidosis compensation, decompensated metabolic alkalosis+respiratory acidosis and electrolyte imbalance may develop. This situation may contribute to the increase in mortality. In conclusion, it should be noted that non-massive, but frequent blood transfusions may result in certain complications.

    Drug testing is a useful tool to identify drug use or monitor adherence to prescription drugs. The interpretation of drug results can be complicated based on the pattern and proportional concentrations of drugs and/or drug metabolite(s). The purpose of this retrospective study was to detect the positivity rates and metabolic patterns of five prescription drugs, including fentanyl, meperidine, methylphenidate, tapentadol and tramadol. Retrospective data were retrieved from the laboratory information system in a national reference laboratory. Drug testing was performed using four mass spectrometry methods that were validated for clinical use. For urine specimens, the positivity rate was the highest for methylphenidate (62.3%, n = 2,489), followed by tramadol (43.7%, n = 3,483), fentanyl (41.9%, n = 4,657), tapentadol (37.9%, n = 736) and meperidine (8.3%, n = 138). Among positive samples, both parent drug and metabolite(s) was detectable in 94.9% of meperidine samples, 94.5% of tramadol samples, 93.8% of fentanyl samples, 89.9% of methylphenidate and 86.6% of tapentadol samples. For serum or plasma specimens, the positivity rate was the highest for tapentadol (75.0%, n = 39), followed by methylphenidate (74.2%, n = 569), fentanyl (53.6%, n = 113), meperidine (41.9%, n = 18) and tramadol (28.9%, n = 213). Similar metabolic patterns were found in serum or plasma. Of positive results, both parent drug and metabolite(s) were found in 94.7% of fentanyl samples, 83.3% of meperidine samples, 79.6% of methylphenidate samples, 53.8% of tapentadol samples and 44.1% of tramadol samples. Our data demonstrates the metabolic patterns of five drugs from a random urine or serum/plasma collection in patients that have been prescribed these medications. The data presented can be used to guide clinicians in determining drug adherence by assessing the positivity rates of the parent drug and corresponding metabolite(s). © The Author 2017.

    Obesity produces greater circulation of free fatty acids (FFA). In adults, the FFA composition changes in states of obesity; in adolescents, the results are contradictory. This study compare the FFA profile of obese youth with and without Metabolic Syndrome (MetS) and explore the association between FFA and metabolic alterations of obesity and MetS. A cross-sectional study with 96 young people between 10 and 18 years old was divided into three groups: 1) obese youth with MetS, 2) obese youth without MetS; and 3) adequate weight (AW), matched according to age, gender, pubertal maturation and socioeconomic stratum. The nutritional status was classified according to the body-mass index (BMI), according to the World Health Organization 2007 (WHO, 2007); the waist circumference (WC), adiposity, lipid profile, highly-sensitive reactive C protein (hsRCP), glucose, insulin and insulin resistance (IR), according to the homeostatic model assessment (HOMA Calculator Version 2.2.2). The FFA serum concentration was determined by gas chromatography. Both obese groups had higher adiposity, inflamation (hsRCP), FFA totals and frequency palmitoleic-16:Jn7, compared to AW. The obese with MetS presented more metabolic alterations, a greater amount of dihomo-γ-linolenic (DHGL-20:3n6) and a 20:3n6/18:2n6 relation, indicative of increased activity of A6 desaturase (D6D). The FFA totals, palmitoleic-l6:1n7, DHGL-20:3n6, D6D activity and hsRCP significantly correlated with variables of adiposity, IR and triglicerides. The results in obese with MetS corroborate the association among central obesity, inflammation and increased lipolysis in visceral adipose tissue and metabolic alterations.

    Full Text Available In the article data are presented on dynamics of the level of indicators of metabolic profile of blood serum of race horses of the Ukrainian riding breed in the conditions of physical and emotional loading. Clinically healthy race horses were the object of  research. Blood was taken from the jugular vein to obtain serum and for further biochemical research. For the research 12 race horses from a training group were chosen. From time to time the animals took part in competitions; they were not specially used in races and were mostly used for the training of junior riders and sportsmen of different levels. Blood was taken in conditions of relative rest after ordinary training and after emotional stress during the entertainment performances when a large number of people were present and loud music was played. In the blood serum the following biochemical indicators were defined: whole protein, urea, creatinine, uric acid, total bilirubin and its fractions, glucose, cholestererol, triacylglycerol, calcium, ferrum, lactate, pyruvate, activity of the AlAT, SGOT, GGTP, LDH, an alkaline phosphatase – which makes it possible to determine reasonably accurately the adaptation potential of a horse under various types of loading. We established that during training and psychoemotional loading of racing horses of the training group of the Ukrainian riding breed, multidirectional changes in the level of biochemical indicators of blood serum occurred, which is evidence of stress in the metabolic processes in the animals’ organisms. Concentration of a biomarker of an oxidative stress, uric acid, increased after physical loading by 8.6%, and after emotional loading by 55.1%, which demonstrates that emotional stress had the more negative effect, indicating insufficient adaptation by the horses before demonstration performances. After physical loading, reaction of transamination in the horses’ liver cells intensified, and after emotional loading its intensity

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

    A serum metabonomic profiling method based on ultra-performance liquid chromatography/time-of-flight mass spectrometry (UHPLC/TOF-MS) was applied to investigate the metabolic changes in hypothyroid rats induced by propylthiouracil (PTU). With Significance Analysis of Microarray (SAM) for classification and selection of biomarkers, 13 potential biomarkers in rat serum were screened out. Furthermore, Ingenuity Pathway Analysis (IPA) was introduced to deeply analyze unique pathways of hypothyroidism that were primarily involved in sphingolipid metabolism, fatty acid transportation, phospholipid metabolism and phenylalanine metabolism. Our results demonstrated that the metabonomic approach integrating with IPA was a promising tool for providing a novel methodological clue to systemically dissect the underlying molecular mechanism of hypothyroidism.

    Both serum uric acid (SUA) and resting heart rate (RHR) are positively associated with metabolic syndrome (MetS). However, little is known regarding the relationship between SUA and RHR. We aimed to investigate the relationship between SUA and RHR in the elderly with MetS. With a retrospective observational analysis, 867 Chinese elderly subjects (437 males and 430 females) were divided into 4 groups according to SUA quartiles. We first investigated the relationship between SUA and MetS. Then we evaluated whether there is an independent association of SUA with RHR in these subjects. There were significant differences of MetS incidence in groups of Quartile 1-4 in male and female (all P0.30, Pmetabolic risk in Chinese elderly.

    Full Text Available Although it has been demonstrated that visceral adipose tissue content and serum levels of adiponectin are associated with metabolic syndrome, their predictive potential for the development of metabolic syndrome remains to be elucidated.We studied 1,130 participants of the Seoul Metabolic Syndrome cohort. A total of 337 subjects without metabolic syndrome underwent the follow-up evaluation and finally analyzed. Visceral fat area (VFA was measured using dual bioelectrical impedance analysis. We compared the 1-year incidence rate of metabolic syndrome among four different groups: Group 1 (high adiponectin level and low VFA, Group 2 (low adiponectin level and low VFA, Group 3 (high adiponectin level and high VFA and Group 4 (low adiponectin level and high VFA.Median follow-up duration was 17 months. Cut-off points of adiponectin level and VFA for metabolic syndrome were 7.34 ng/ml and 84 cm2 for men, and 12.55 and 58 cm2 ng/ml for women, respectively. The incidence of metabolic syndrome was the highest in Group 4 (Group 1; 16.47%, Group 2; 22.08%, Group 3; 25%, and Group 4; 46.15%, p<0.001. Adjusted logistic regression analyses for metabolic syndrome prediction demonstrated that Group 4 exhibited the highest odds ratio compared with Group 1 (4.918 [2.05-11.795], which was predominantly affected by waist circumference and serum triglyceride levels. Notably, triglyceride/high-density lipoprotein cholesterol (TG/HDL ratio was significantly higher in Group 4 (p = 0.017.Incidence rate of metabolic syndrome was the highest in subjects with low serum adiponectin levels and high visceral fat area. Higher TG/HDL ratio in these subjects suggested insulin resistance may contribute to the development of metabolic syndrome.

    The ratio of serum leptin to adiponectin (L/A ratio) could be used as a marker for insulin resistance. However, few prospective studies have investigated the impact of L/A ratio on improvement of metabolic components in high-risk individuals with metabolic syndrome. We examined the association between L/A ratio and the regression of metabolic syndrome in a population-based longitudinal study. A total of 1017 subjects (431 men and 586 women) with metabolic syndrome at baseline (2005-2008) were examined and followed (2008-2011). Baseline serum levels of leptin and adiponectin were analyzed by radioimmunoassay. Area under the receiver operating characteristics curve (AUROC) analyses were used to assess the predictive ability of L/A ratio for the regression of metabolic syndrome. During an average of 2.8 years of follow-up, metabolic syndrome disappeared in 142 men (32.9%) and 196 women (33.4%). After multivariable adjustment, the odds ratios (95% confidence interval) for regression of metabolic syndrome in comparisons of the lowest to the highest tertiles of L/A ratio were 1.84 (1.02-3.31) in men and 2.32 (1.37-3.91) in women. In AUROC analyses, L/A ratio had a greater predictive power than serum adiponectin for the regression of metabolic syndrome in both men (p=0.024) and women (p=0.019). Low L/A ratio is a predictor for the regression of metabolic syndrome. The L/A ratio could be a useful clinical marker for management of high-risk individuals with metabolic syndrome.

    Type 2 diabetes mellitus (T2DM) has become a growing worldwide problem of public health importance. Insulin resistance is commonly associated with obesity and a key factor mediating the progression to T2DM. The failure of insulin-sensitive peripheral tissues to respond to insulin results in an increase in serum glucose levels that leads to an impaired homeostatic state. Skeletal muscle plays a crucial role in maintaining glucose metabolism. Impairments in both glucose and lipid metabolism ari...

    Effects of diets on growth, serum biochemical indices, and enzyme activities related to lipid metabolism in fingerlings Coilia nasus at age of 6 months were investigated during 60-day experiment in this study. Fingerlings with similar body length and mass were fed with one of 3 types of diets (diet 1: soft pellet; diet 2: soft pellet mixed with fish oil; diet 3: slow-sinking hard pellet). Fish fed with diets 2 or 3 had significantly higher total body mass, rate of mass gain, specific growth rate, and fullness coefficient than those fed with diet 1. Fish fed with diet 3 exhibited the lower food coefficient compared to those fed with diets 1 or 2. Growth traits (length, length to mass ratio, length to width ratio, hepatopancreas somatic indices and viscera somatic index) and serum biochemical indices (total protein, albumin, blood glucose, cholesterol and triglycerides) in all three treatments were not significantly different. Fish fed with diet 1 exhibited significantly higher carnitine palmitoyltransferase-I than those fed with diets 2 or 3, while fish fed with diet 2 exhibited significantly lower carnitine palmitoyltransferase-II. However, amylase, pepsin, lipase activity, lipoprotein lipase and acetyl-coa carboxylase had no significant difference in fish body among all groups. Results suggested that fish oil as a diet supplement highly facilitated fish growing. The slow-sinking pellet had the highest utilization efficiency and was suitable to feed fish fingerlings of C. nasus.

    Uric acid (UA) is known to be associated with excess adiposity and insulin resistance. Our aim was to investigate the relationship between UA and the factors associated with the metabolic syndrome and type 2 diabetes mellitus (T2DM), both initially and longitudinally. Serum UA was assessed as a potential determinant of concurrent blood pressure, serum lipids, glucose regulation measured via an oral glucose tolerance test (OGTT), acute insulin response (AIR), and insulin action (M) measured with hyperinsulinemic-euglycemic clamps in 245 participants (72% Native American, 56% male). UA was also assessed as a predictor of the above variables in 60 participants with follow-up data available (median follow-up time=11.2 years [interquartile range (IQR)=8.1, 13.6 years]. The impact of UA on the risk of T2DM was determined as 36 of the 245 participants developed T2DM after the baseline visit. UA was negatively associated with both concurrent and future M, such that for every 1 mg/dL increase in serum UA, M decreased 7.6% (P<0.001) and future M decreased 6.3% (P=0.02). However, UA was not associated with AIR (P=0.7). UA concentrations were a predictor of T2DM [hazard risk ratio (HRR)=1.5; P=0.02]. UA was positively associated with both concurrent blood pressure and lipids and also predicted future increases in blood pressure and total cholesterol. Not only did UA associate with concomitant insulin action, blood pressure, and lipids, it also predicted future declines in insulin action and T2DM. UA is a potential target for preventing decreases in insulin sensitivity and rises in blood pressure and cholesterol.

    Serum uric acid (SUA) is a potential risk factor for atherosclerosis. We assessed the relationship between SUA and subclinical atherosclerosis in Korean men (n = 3010). Multidetector computed tomography (MDCT) and ultrasonographic measurements of coronary artery calcification (CAC) and carotid intima-media thickness (cIMT), respectively, are markers of subclinical atherosclerosis. Odds ratios (ORs) of CAC score and cIMT across SUA levels were 1.101 (P = .046) and 1.266 (P = .002), respectively, after adjustment for several variables. The independent association between CAC and cIMT was observed (OR = 1.231, P uric acid was independently associated with metabolic syndrome (MetS) with an OR of 1.415 (P Metabolic syndrome was only independently associated with cIMT, with an OR of 2.103 (P = .003). High-sensitivity C-reactive protein was positively correlated with SUA (r = .125, P uric acid level is independently associated with CAC, cIMT, and MetS in Korean men.

    Recent studies have demonstrated an association between serum uric acid (SUA) levels and metabolic syndrome (MetS). However, paucity of available data regarding the cause and effect relationship between SUA and MetS in healthy adults is still a big challenge which remains to be studied. Therefore, we investigated whether SUA predicts new onset of MetS in a population-based cohort study. The study included 1590 adults (661 men and 929 women) aged 40-70 years without MetS at baseline (2005-2008) and subjects were prospectively followed for 2.6 years. To evaluate the relationship between SUA and MetS, we divided the aforementioned subjects into quintiles (SUA-I to SUA-V) from the lowest to the highest values of SUA. SUA was measured by the enzymatic colorimetric method. We used category-free net reclassification improvement (NRI) and integrated discrimination improvement (IDI) to characterize the performance of predicted model. During a mean of 2.6 years of follow-up, 261(16.4%) adults developed MetS. MetS variables were significantly related to the baseline SUA level. Waist circumference (WC), blood pressure (BP), and serum triglyceride (TG) were significantly higher in the highest quintile of SUA compared to the lowest SUA quintile in men and women. After adjustment for age, total cholesterol and low-density lipoprotein cholesterol (LDL-C) in men and women, subjects in the fifth quintiles of SUA showed significantly higher ORs for incident MetS. The association between hyperuricemia and new onset of MetS were consistently stronger in women than men. Additionally, among women, we found an improvement in the area under the ROC curve in the models that added SUA to core components of MetS. Our study suggests that SUA is significantly correlated with future risk of WC, BP, TG and may predicted as a risk factor for developing MetS. SUA may have a clinical role in predicting new-onset metabolic syndrome among women. Large prospective study is needed to reveal the clinical

    Hyperuricemia is related to Metabolic Syndrome (MetS) and cardiovascular diseases, but the use of serum uric acid (UA) to diagnose MetS is currently ignored in clinical practices. To examine the impact of serum UA on the diagnostic of MetS and the relationship of serum UA with cardiometabolic risk factors in apparently healthy Brazilian middle-aged men residents in a city of Minas Gerais. In a cross-sectional analysis, 289 apparently healthy middle-aged men underwent anthropometric, clinical, sociodemographic and blood serum biochemical evaluation. By using receive operating curve the internal cutoff of serum UA was determined (5.25 mg/dL). Subjects with two or more components of MetS exhibited higher serum UA as compared to those with one or none component. The inclusion of serum UA ≥ 5.25mg/dL as an additional component of MetS increased the occurrence of this syndrome by 13%. Subjects with UA ≥ 5.25mg/dL showed high prevalence for MetS and association with its components (central obesity, hypertriglyceridemia, dyslipidemia and hypertension) as well as atherogenic risk. Serum UA has an important impact on the diagnostic of MetS and is related to cardiometabolic risk factors in apparently healthy Brazilian middle-aged men. Its use in clinical practices could aggregate accuracy to diagnose MetS. Copyright AULA MEDICA EDICIONES 2014. Published by AULA MEDICA. All rights reserved.

  1. Serum total bilirubin levels are negatively correlated with metabolic syndrome in aged Chinese women: a community-based study

    P. Zhong

    Full Text Available We evaluated serum total bilirubin levels as a predictor for metabolic syndrome (MetS and investigated the relationship between serum total bilirubin levels and MetS prevalence. This cross-sectional study included 1728 participants over 65 years of age from Eastern China. Anthropometric data, lifestyle information, and previous medical history were collected. We then measured serum levels of fasting blood-glucose, total cholesterol, triglycerides, and total bilirubin, as well as alanine aminotransferase activity. The prevalence of MetS and each of its individual component were calculated per quartile of total bilirubin level. Logistic regression was used to assess the correlation between serum total bilirubin levels and MetS. Total bilirubin level in the women who did not have MetS was significantly higher than in those who had MetS (P<0.001. Serum total bilirubin quartiles were linearly and negatively correlated with MetS prevalence and hypertriglyceridemia (HTG in females (P<0.005. Logistic regression showed that serum total bilirubin was an independent predictor of MetS for females (OR: 0.910, 95%CI: 0.863–0.960; P=0.001. The present study suggests that physiological levels of serum total bilirubin might be an independent risk factor for aged Chinese women, and the prevalence of MetS and HTG are negatively correlated to serum total bilirubin levels.

    There is controversial evidence on association of serum acid uric (SUA) with cardiometabolic risk factors and metabolic syndrome in adults. This study aimed to investigate the associations of SUA levels, components of metabolic syndrome, and other cardiometabolic risk factors, in a nationally representative sample of Iranian adolescents. This study included 132 participants who met the criteria of metabolic syndrome and 235 participants without metabolic syndrome. The participants were grouped according to the tertiles of SUA. Metabolic syndrome was defined according to the Adult Treatment Panel III criteria modified for children and adolescents. The relationship between SUA and cardiometabolic risk factors and metabolic syndrome was assessed by multivariable logistic regression analysis. The mean age of the participants was 15.21 ± 2.35 years, with no significant difference between the boys and the girls. The participants whose SUA was categorized in the 2nd tertile and those falling into the 3rd tertile had significantly higher systolic blood pressure (P Metabolic syndrome was associated with the 2nd and 3rd tertiles of SUA as compared to the lower tertile(s), in the adjusted model (P metabolic syndrome had higher SUA levels. Its association with some components of metabolic syndrome supports that SUA might be an additional component of metabolic syndrome even during adolescence.

    Serum uric acid (SUA) has been suggested as a potentially modifiable mediator associated with the metabolic syndrome. Hyperuricemia and metabolic syndrome were both associated with adverse renal outcome. However, epidemiologic data are limited regarding this relationship in patients with type 2 diabetes mellitus (T2DM). This study aims to determine whether elevated SUA is associated with an increased prevalence of metabolic risk factors, albuminuria, and chronic kidney disease (CKD) in a large sample of patients with T2DM. It also examines the combined effect of SUA and metabolic syndrome components on the odds of CKD. A total of 1463 patients with T2DM were recruited. Blood samples were obtained to measure metabolic parameters. Patients with macroalbuminuria or an estimated glomerular filtration rate of metabolic syndrome, central obesity, hypertension, high triglycerides (TGs), CKD, and macroalbuminuria was significantly higher in patients with hyperuricemia than those in the lowest tertile of SUA (T1). One standard deviation (SD) increment of SUA was significantly associated with metabolic syndrome, central obesity, and high TGs after adjustment for age, sex, estimated glomerular filtration rate (eGFR), and albuminuria. The odds of CKD went up to 1.37-fold with every 1 SD increment of SUA, independent of age, sex, and components of metabolic syndrome. There was a significant, graded increase in odds of CKD by increasing SUA levels and the number of metabolic syndrome risk factors (Pmetabolic syndrome components on the odds of CKD.

    Background: The aim of this study was to evaluate the associations between alanine aminotransferase (ALT) and aspartate aminotransferase (AST) with metabolic syndrome (MetS) in the general Chinese population. Methods: This study was a multicenter, cross-sectional study which was conducted in rural areas of China from the 2012 to 2013 Northeast China Rural Cardiovascular Health Study (NCRCHS), and 11,573 adults with complete data were included in our final analysis. Elevated ALT and AST levels were defined as >40 U/L. Serum ALT and AST levels within the reference range were divided into quartiles, and their associations with MetS were evaluated by logistic regressions. Results: A total of 7.4% and 3.5% participants had elevated serum ALT and AST levels, respectively. The prevalence of MetS was 37.3% in males and 45.8% in females. After adjusting for potential confounders, we found ALT level elevation, even within the reference range, was independently associated with MetS. The odds ratio (OR) values of MetS in the ALT quartiles 2–4 groups within the reference range were 1.113 (95% CI: 1.019–1.280), 1.375 (95% CI: 1.212–1.560), 1.878 (95% CI: 1.650–2.138) compared with the ALT quartile 1 group, and OR in the elevated ALT group was 3.020 (95% CI: 2.496–3.653). Positive relationship for MetS was also observed in elevated AST group (OR: 1.689, 95% CI: 1.314–2.171), but within the reference range, the AST level was not associated with MetS. Conclusions: Serum ALT level, even within the reference range, was significantly associated with MetS. However, only elevated AST levels above 40 U/L was positively associated with MetS. Within the reference range, we did not find a relationship between AST levels and MetS. PMID:26901209

    The aim of this study was to investigate associations of serum zinc with incident metabolic syndrome and its components in middle-aged and older Finnish men. An 11-y prospective follow-up study conducted among 683 men from the Kuopio Ischaemic Heart Disease Risk Factor Study who were 42 to 60 y old at baseline in 1984 to 1989. The main outcome was incident metabolic syndrome, defined by the National Cholesterol Education Program (NCEP) criteria. Other outcomes were the individual components of the NCEP metabolic syndrome: Fasting blood glucose, serum triacylglycerols, serum high-density lipoprotein (HDL) cholesterol, hypertension, and waist circumference. During the average follow-up of 11 y, 139 men (20.4%) developed metabolic syndrome. Those in the highest tertile of serum zinc had 84% higher risk (95% confidence interval 12 to 201%, P trend across tertiles = 0.015) to develop metabolic syndrome compared with those in the lowest tertile, after adjustment for several potential confounders. The association between serum zinc and incident metabolic syndrome was attenuated by adjustment for waist circumference, serum HDL cholesterol, or hypertension. Serum zinc was also directly associated with higher waist circumference and hypertension and inversely associated with HDL cholesterol at the 11 y examinations. We found a direct association between serum zinc and incidence of metabolic syndrome in middle-aged and older eastern Finnish men. Further studies are warranted to explore the mechanisms.

    Childhood obesity is associated with cardiovascular abnormalities but little is known on the potential correlation between early cardiovascular and metabolic alterations. Aims of this study were 1) to evaluate early cardiovascular abnormalities in a large population of obese children and adolescents compared with a normal weight counterpart, 2) to investigate their potential association with insulin resistance (IR), serum uric acid (sUA) and metabolic syndrome (MetS). This was a single-center case-control study. Eighty obese (OB) subjects (6-16years) and 20 normal weight (NW) matched controls were consecutively recruited. In the whole population we performed an anthropometric and a cardiovascular assessment. OB patients also underwent an OGTT and biochemical evaluations. OB children showed greater left atrial (LA) and ventricular (LV) dimensions and mass and higher carotid artery intima-media thickness (CIMT), compared with NW controls. The BMI z-score, waist circumference, IR and sUA were positively related with LA and LV dimensions and mass. OB subjects with MetS (46.3%) showed greater LA diameter (p=0.001) and LV area (p=0.01) and volume (p=0.04) compared with OB children without MetS. LA diameter and LV dimensions and mass were significantly dependent on the number of criteria for MetS. Mets, sUA and IR were significant predictors of left heart dimensions and mass in obese children. Obesity and MetS are associated with abnormal cardiovascular response during childhood. Hyperuricemia can be an early marker of cardiovascular dysfunction and the routine determination of circulating levels of sUA should be implemented during risk stratification among pediatric age.

    The objective of this study was to quantify the genetic diversity among breeds under evaluation for tropical adaptability traits that affect the performance of beef cattle at the USDA/ARS SubTropical Agricultural Research Station (STARS) near Brooksville, FL, USA. Twenty-six microsatellite loci were used to estimate parameters of genetic diversity among the breeds American Brahman, Angus, Senepol and Romosinuano; the latter was comprised of two distinct bloodlines (Costa Rican and Venezuelan). Genotypes of 47 animals from each of these STARS herds were analysed for genetic diversity and genetic distance. Using two methods, the greatest genetic distance was detected between the Costa Rican line of Romosinuano and the Senepol. Gene diversity ranged between 0.64 (Costa Rican line of Romosinuano) and 0.75 (American Brahman). The breed relationship inferences, which are based on genetic distance, provide additional tools for consideration in future crossbreeding studies and for testing the relationship between quantified breed diversity and observed heterosis.

  8. Brahmanical idealism, anarchical individualism, and the dynamics of Indian negotiating behavior

    The article analyzes the implications of the Indian mind set on the dynamics of the Indian negotiating behavior. I argue that the constructs of Brahmanical idealism and anarchical individualism capture the nature of the Indian mind set. Brahmanical idealism reflects the tendency of the decision...... focuses on the purity of the mental world, anarchical individualism lays primacy of attaining the ideal solution through absolutist forms of interpersonal behavior. That is to say, since each individual is engaged in searching for the ideal solution , and furthermore as each individuals ideal solution...... is either no better or worse than that of their counterpart, the attainment of this ideal is problematical because under these conditions cooperative behavior is a rarity. In this sense anarchic individualism fragments rather than enhances total effort, thereby draining energy away from the system. I...

    Full Text Available Failure of penile protrusion during attempted service of a cow on heat was investigated in a 3-year-old Brahman bull at Kwakwadi cattle-post in the Kgalahadi sandveld, Kweneng District, Botswana. The investigation revealed that penile protrusion was obstructed by a devil's claw (grapple thorn, a dry fruit of the plant Harpagophytum procumbens, which had lodged in the cavum preputiale. The thorn, which was removed almost completely manually with minimal tissue dissection, had also caused minor lacerations and puncture wounds on the lamina interna pars parietalis. The wounds healed well following treatment with antiseptics and antibiotics and subsequently the bull regained full penile protrusion and served the cows well. This report describes the first case of lodgement of a devil's claw fruit in, and its extraction from, the cavum preputiale of a Brahman.

    Full Text Available As there is effective intervention for delaying or preventing metabolic diseases, which are often present for years before becoming clinically apparent, novel biomarkers that would mark metabolic complications before the onset of metabolic disease should be identified. We investigated the role of fasting serum amino acids and their associations with inflammatory markers, adipokines, and metabolic syndrome (MetS components in subjects prior to the onset of insulin resistance (IR. Anthropometric measurements, food records, adipokines, biochemical markers, and serum levels of amino acids were determined in 96 asymptomatic subjects aged 25–49 years divided into three groups according to the number of MetS components present. Cysteine and tyrosine were significantly higher already in group with one component of MetS present compared to subjects without MetS components. Serum amino acid levels correlated with markers of inflammation and adipokines. Alanine and glycine explained 10% of insulin resistance variability. The role of tyrosine and cysteine, that were higher already with 1 component of MetS present, should be further investigated as they might point to future insulin disturbances.

    To investigate the nature of the relationships between uric acid and metabolic syndrome (MetS) components. Body mass index, waist circumference, serum uric acid, fasting glucose, lipid profiles, and blood pressure were measured in 13,811 subjects aged between 18 and 85 years of age. Two structural equation models (SEMs) were used to test a hypothesis regarding the linking roles of uric acid in the occurrence of MetS components in male and female separately. The findings of the SEM demonstrated that increased uric acid level was associated with fasting glucose (beta = 0.221, P uric acid level was associated with decreased fasting glucose (beta = -0.071, P uric acid and lipid profiles than those between uric acid and other MetS components. By using SEM, we were able to confirm the intimate relationships between uric acid and MetS components, particularly in women. The associations between uric acid and MetS components were gender specific, and the nature of such association requires further exploration. Copyright © 2012 National Lipid Association.

    To investigate the association of serum resistin levels with metabolic syndrome (MS) and early atherosclerosis in obese children. A total of 176 obese children and 88 healthy children were enrolled in this study, and were gender and age matched. Obesity was defined as a body mass index (BMI) of ≥ the 95th percentile for age and sex. All children had a physical examination and routine hematology testing for fasting blood glucose, insulin, and lipids profile. Homeostasis model of assessment of insulin resistance (HOMA-IR) was calculated, as insulin resistance has a central role in the pathophysiology of MS. Non-invasive ultrasound measurement was obtained to investigate carotid intima-media thickness (IMT) as the markers of early atherosclerosis. Path analysis was used to evaluate the value of resistin levels to early atherosclerosis. The resistin levels were higher in obese children compared to healthy children (23.14 ± 7.35 vs. 17.1 ± 5.7 ng/mL, pobese children.

    Full Text Available Metabolic syndrome is a medical disorder characterized by obesity, hyperglycemia, dyslipidemia, and hypertension. Thyroid hormone has been shown to affect many metabolic processes. This study was undertaken to explore the relationship between serum thyrotropin and components of metabolic syndrome in Chinese adolescents. Waist circumference (76.4 ± 10.7 versus 70.0 ± 10.6 cm, P = 0.006 and body mass index (23.90 ± 4.20 versus 21.51 ± 4.16 kg/m2, P = 0.011 were significantly greater among adolescents with subclinical hypothyroidism compared with euthyroid subjects. The risk of obesity in the subclinical hypothyroid group was 3.444 times that in the euthyroid group (odds ratio = 3.444, 95% confidence interval (CI: 1.570–7.553. Serum TSH was significantly positively correlated with waist circumference (β = 1.512, P = 0.019, TC (β = 0.160, P = 0.003, LDL-C (β = 0.032, P = 0.008, and TG (β = 0.095, P = 0.001. The TSH level in the metabolic syndrome group was significantly higher than that in nonmetabolic syndrome group (2.65 [2.28–3.80] versus 2.53 [1.92–3.45] mIU/L, P = 0.032. Serum TSH within the reference range was positively associated with TC (β = 0.173, P = 0.013, LDL-C (β = 0.031, P = 0.043, and TG (β = 0.132, P = 0.021. Increased serum TSH in adolescents may be a potential risk factor for metabolic syndrome.

    We examined the cytogenetics of mithun (Bos frontalis), a domesticated version of the Asian gaur, and hybrids (F(1) generation) produced by artificial insemination of Brahman cows (Bos indicus) with mithun semen. Reproductive potential was also examined in the F(1) generation and a backcrossed heifer for utilization of heterosis. Metaphase chromosome spreads were examined by conventional staining and fluorescence in situ hybridization hybridized with the entire chromosome 1 of mithun as a specific probe. Chromosome 1 of mithun was found to be equivalent to Bos taurus chromosomes 2 and 28. The karyotype of the female mithun (N = 4) comprised 58 chromosomes, including 54 acrocentric and four large submetacentric chromosomes, without the four acrocentric chromosomes found in the domesticated species B. indicus. However, one of the four female mithuns with a normal mithun phenotype had an abnormal karyotype (2n = 59), indicating introgression from B. taurus or B. indicus. The F(1) karyotypes (N = 6, 3♂3♀) of the mithun bull × Brahman cow cross had 2n = 59, intermediate between their parents; they were consistent heterozygous carriers with a centric fusion involving rob(2;28), as expected. Two pronounced red signals were seen in the mithun karyotypes, three red signals in the mithun × Brahman hybrids, and four red signals in the Brahman cattle, in good agreement with centric fusion of bovine rob(2;28). The female backcross hybrid (N = 1) with 2n = 59 had a similar chromosome configuration to the F(1) karyotypes and had rob(2;28). Such female backcross hybrids normally reproduce; however, the F(1) bulls (N = 3) had not yet generated normal sperm at 24 months.

    To analyze the interdependent relationship between serum bone metabolic markers and traditional Chinese medicine (TCM) syndromes in patients with chronic kidney disease (stages 3 and 4)-related mineral and bone disorder (CKD-MBD), in order to provide the objective basis for exploring the rules of TCM syndrome differentiation in patients with CKD-MBD. The retrospective survey was conducted to collect 105 cases with CKD (stages 3 and 4)-MBD. General clinical indexes, frequency of TCM syndromes and distribution of TCM syndrome type were investigated. Furthermore, serum bone metabolic markers, including calcium (Ca2+), phosphonium (P3+), intact parathyroid hormone (iPTH), alkaline phosphatase (ALP), procollagen type 1 amino-N-terminal propeptide (P1NP) and β-crosslaps (β-CTX) were analyzed, respectively. Meanwhile, bone mineral density (BMD) was assessed. And then, the multivariate regression analysis was performed for serum bone metabolic markers and TCM syndromes. The results showed that the general clinical features of the 105 patients included old age, hypertension, fracture, loss of bone mass and mild abnormalities of serum bone metabolic markers. High-frequency TCM syndromes were related to Yang deficiency in Spleen and Kidney, Qi deficiency in Spleen and Kidney and blood stasis. Moreover, Yang deficiency in Spleen and Kidney and blood stasis were found as the most frequent characteristics of the distribution of TCM syndromes type. The clinical characteristics of patients with the syndrome type of Yang deficiency in Spleen and Kidney were probably old age, increase in TCM syndrome scores and abnormalities in iPTH and P1NP. In addition, the interdependent relationship between abnormality in Ca2+ and syndromes of hair loss, tooth shake and sexual dysfunction, abnormality in P3+ and syndromes of aches in waist and knees, abnormality in iPTH and syndromes of soreness and weakness in waist and knees, lassitude, fatigue and extreme chilliness, abnormality in ALP and

    This study was designed to evaluate the influence of racing on the serum concentrations of the acute-phase proteins (APPs) C-reactive protein (CRP), haptoglobin (Hp) and serum amyloid A (SAA) in 32 endurance-racing greyhounds. The study also aimed to investigate the effect of a 7 km race on the bone biomarkers osteocalcin (OC), bone-specific alkaline phosphatase (b-ALP) and pyridinoline cross-links (PYD). Total white blood cell (WBC) count, and the serum concentrations of cortisol, tumour necrosis factor-α (TNF-α), vitamin D and testosterone were also determined. Blood samples were collected 24 h prior to (T0) and within 2 h of completion of the race (T1). Compared to baseline values, WBC count did not change significantly (P = 0.2300), serum cortisol, Hp and SAA increased, while TNF-α and CRP decreased (P race serum concentrations of OC and PYD (P = 0.9500 and P = 0.2600, respectively), but serum b-ALP increased significantly (P = 0.0004). Serum concentrations of vitamin D and testosterone increased after racing (P = 0.0100 and P race stimulated an acute-phase response, demonstrated by significant increases in the serum concentrations Hp and SAA in racing greyhounds. Increased serum b-ALP post-race probably indicates a change in bone metabolism and deserves further study. Copyright © 2014 Elsevier Ltd. All rights reserved.

    We investigated heat tolerance and growth rate in two trials under ambient conditions in central Florida. Trial 1 (1994) involved 38 Brahman (B), 21 Senepol (S), 19 B x Angus (A), 20 S x A, and 20 Tuli (T) x A heifers. Trial 2 (1995) involved 13 A, 35 B, 30 S, 23 B x A, 17 S x A, and 28 T x A heifers. Measurements were made on three consecutive weeks during the hotter and cooler seasons of each year and included rectal temperature (RT, degrees C), respiration rate (RR, bpm), temperament score (TS; 1 = very docile, 5 = very aggressive), blood packed-cell volume (PCV), and plasma cortisol concentration (CORT). Data for RT were transformed (log10 [RT - 37]) before analysis. On the hottest date in Trial 1, log10 RT was not different between B (.39 +/- .011) and B x A (.37 +/- .016) or between T x A (.35 +/- .015) and B x A, but log10 RT was lower (P Senepol, Brahman) with a temperate breed (Angus) is similar to heat tolerance displayed by purebred tropical breeds (Senepol, Brahman).

    To investigate the correlation of serum leptin and to energy consumption and metabolization in the patients with chronic obstructive pulmonary disease (COPD). We included 92 outpatients with stable COPD in West China Hospital of Sichuan University as trail group (COPD group) and 80 healthy elderly people in community as control group. All patients and healthy control received the measurements of body mass index (BMI), fat mass, resting energy expenditure (REE), lung function, serum leptin and tumor necrosis factor-α (TNF-α). The concentrations of serum leptin, BMI and lung function were lower in COPD group than those in control group (P leptin between two groups were not difference after the adjusted results of BMI and fat mass.. There was no difference of REE and TNF-α concentrations in these two groups. The serum leptin had positive correlation with BMI and fat mass, but there were no correlation between of TNF-α and serum leptin. In elderly people with stable COPD, the decline on the serum leptin is related to the decrease of BMI and fat mass, but barely related to the level of TNF-α.

    To investigate the relationship of adiponectin, leptin, resistin and RBP4 levels in obese and metabolic syndrome children with nonalcoholic fatty liver disease (NAFLD). Group I consisted of 63 obese children with liver steatosis, group II consisted of 12 obese children with elevated serum ALT activity from group I, and group III included 85 obese children without liver steatosis. Leptin levels were higher in the NAFLD children than in the control group. Serum RBP4 levels in obese children with NAFLD were higher than those in obese children without NAFLD and controls. Adiponectin and resistin levels were negatively correlated and RBP4 levels positively correlated with ALT activity and ultrasonographic grading. These data suggest that adiponectin, resistin and RBP4 may have a role in the pathogenesis of NAFLD in obese children. Adiponectin, leptin, resistin and RBP4 may be suitable markers for predicting metabolic syndrome and NAFLD.

    To compare the 2-year effects of raloxifene (Rlx) with oral postmenopausal hormone therapy (HT) on serum markers of brain and whole-body cholesterol metabolism. In a randomized, double-blind, placebo-controlled trial, 95 healthy, non-hysterectomized, early postmenopausal women received either daily Rlx 60 mg (n = 24), Rlx 150 mg (n = 23), HT (conjugated equine estrogens 0.625 mg/medroxyprogesterone acetate 2.5 mg; n = 24), or placebo (n = 24). Fasting blood samples were collected at baseline and after 6, 12, and 24 months of treatment for measurement of serum concentrations of cholesterol by means of gas-liquid chromatography; 24S-hydroxycholesterol (cerebrosterol), lathosterol, and the plant sterol campesterol by means of gas-liquid chromatography-mass spectrometry. The analyses were performed retrospectively from serum samples stored at -70 degrees C for 5 years. Twenty-four months of treatment with raloxifene 150 mg was associated with a significant reduction in serum cholesterol concentrations (-10%, P = 0.007). The ratio of 24S-hydroxycholesterol to cholesterol, a serum marker of brain cholesterol metabolism, showed a significant increase after 6 and 12 months with raloxifene 150 mg but not after 24 months (P = 0.001). The ratio of lathosterol to cholesterol, a marker of whole-body cholesterol synthesis, increased with raloxifene 60 mg (P = 0.163), raloxifene 150 mg (P cholesterol, a marker of cholesterol absorption rate, was significantly reduced with HT (P = 0.002). Two-year treatment with raloxifene or HT had no influence on brain cholesterol metabolism, while whole-body cholesterol synthesis, assessed by the ratio of lathosterol to cholesterol, increased during raloxifene and HT.

    Full Text Available Background: Metabolic syndrome (MetS is rapidly rising at an alarming rate through all parts of the world. Elevated serum aminotransferase was proposed as a marker for early detection of MetS. In this investigation we primarily aimed to evaluate the prevalence of MetS and its components among army and secondly to explore the association between elevated serum aminotransferase and the components of metabolic syndrome. Methods: A total of 380 army personnel from a military camp in Southern Iran participated in this cross-sectional study. Life style related characteristics, anthropometric features, serum aminotransferase and components of MetS, based on National Cholesterol Education Program—Adult Treatment Panel III, were measured. Statistical significant was set as p value less than 0.05. Results: The mean age of participants was 35.0± 7.5 year-old and the prevalence of metabolic syndrome was 8.1%. The prevalence of the components of MetS including; central obesity, abnormal fasting blood glucose, hypertension, hypertriglycridemia and low HDL cholesterol level was 8.6%, 10.4%, 18.5%, 31%, and 45.5% respectively. MetS had significant relationship with obesity (P<0.001 and abnormal Waist Circumferance/Hip Circumference ratio (P<0.001. Twenty-six percent of subjects had ALT ≥ 41 U/L and 4.9% of them had ALT ≥ 81. Elevated serum aminotransferase had significant association with presence of MetS (P= 0.007. Conclusion: Although prevalence of metabolic syndrome among the studied army population was not high, life style modification of army members is recommended. Liver function tests should be included in routine health checkup of military personnel.

    Full Text Available The aim of this study was to test hypothesis that genotype TT in Czech Pied bulls, associated with higher leptinemia, will have significant effect on energy metabolism parameters in blood serum. The experiment was performed on the Czech Pied bulls in average age of 253 ± 13 days. The animals were sorted out into three groups according to the leptin genotype. The genotype TT was represented 20 animals, CT was represented 143 animals and CC was represented 127 animals. In the blood serum β-hydroxybutyrate (BHB and non-esterified fatty acid (NEFA were analyzed. One-way ANOVA revealed significant relation between serum concentration of NEFA and SNP genotype in leptin gene of Czech Pied bulls, but we failed to verify the hypothesis that genotype TT could affect some of monitored parameters.

    The association between serum uric acid (SUA) levels and metabolic syndrome (MetS) has recently been reported in several cross-sectional and longitudinal studies. We investigated SUA as a biomarker to predict future development of MetS in healthy Korean men without diabetes or hypertension and determined the optimal cut-off levels of SUA. A retrospective cohort study was conducted using data from healthy men who received a general health check-up in 2003. A total of 1809 participants free of MetS, diabetes and hypertension was enrolled. Participants were classified into three groups based on SUA levels: group 1 (<5.5 mg/dL), group 2 (5.5-6.9 mg/dL) and group 3 (≥7.0 mg/dL). During 13,802 person-years of follow up, 127 participants developed MetS. After adjusting for multiple associated parameters, SUA was significantly associated with incident MetS (hazard ratios comparing groups 2 and 3 vs group 1, 2.45 and 3.47 respectively; P < 0.001). In receiver operating characteristic curve analysis, the optimal cut-off level for SUA to predict the development of MetS was 6.5 mg/dL. Our results indicate that an increased level of SUA, even within the normal range, is associated with future development of MetS in healthy middle-aged men. © 2014 The Authors; Internal Medicine Journal © 2014 Royal Australasian College of Physicians.

    Serum levels of uric acid (UA) are associated with metabolic syndrome (MetS). However, no study has been aimed to investigate whether baseline UA is a predictor of MetS in a Japanese population. The multivariable adjusted hazard ratios (HRs) of MetS through 3 years were calculated for each 1 SD increase in baseline UA, for the higher quartiles of baseline UA compared with the lowest quartile, and for baseline hyperuricemia defined as ≥7.0 mg/dl for men and ≥6.0 mg/dl for women in apparently healthy 1,606 men aged 51.7 ± 9.4 years and 953 women aged 51.6 ± 9.4 years who visited a medical check-up center in Japan. The HRs (95 % confidence interval; p value) were 1.282 (1.097-1.499; 0.002) in men and 1.354 (1.041-1.762; 0.024) in women for 1 SD increase in baseline UA, 2.206 (1.344-3.620; 0.002) in men and 3.110 (1.121-8.627; 0.029) in women for the highest quartile of baseline UA compared with the lowest quartile, and 1.900 (1.376-2.622; <0.001) in men and 2.088 (1.040-4.190; 0.038) in women for baseline hyperuricemia adjusting for the pre-existing components of MetS, age, smoking, drinking, physical activity, use of antihypertensive, antihyperlipidemic, and antidiabetic medications and histories of coronary heart disease and stroke. However, no significant association was found between longitudinal changes in UA and incident MetS. Baseline UA is an independent predictor of MetS in a Japanese health screening population.

Forty-eight newborn Hu lambs (birth weight, 2.53 ± 0.14 kg were randomly divided into 4 groups. The lambs in control group (ER suckled their dams. The lambs in other three experimental groups were weaned on milk replacer at 10, 20, and 30 days of age (EW10, EW20, and EW30 groups, respectively. The results were as follows: 1 lambs in EW10 and EW30 groups had a lower (P  0.05 among groups; however, the apparent digestibility and deposition of calcium in early weaned lambs were lower (P < 0.05 than those in ewe-reared lambs. 4 The albumin content in EW30 group was lower (P < 0.05 than that in ER group; the globulin content in EW30 group was higher (P < 0.05 than that in other groups; the content of serum insulin-like growth factor-Ⅰ in weaned lambs tended to increase compared with lambs in ER group. Finally, the growth rate of lambs decreased within 10 days post-weaning, but early weaning boosted creep feed intake, leading to better growth and health later in life. The Hu lambs can be weaned on milk replacer and creep feed at 10 days of age.

    Full Text Available To re-evaluate virulence of Mycobacterium tuberculosis (M. tb in cattle, we experimentally infected calves with M. tb andMycobacterium bovisvia intratracheal injection at a dose of 2.0×10(7 CFU and observed the animals for 33 weeks. The intradermal tuberculin test and IFN-γin vitro release assay showed that both M. tb and M. bovis induced similar responses. Immunohistochemical staining of pulmonary lymph nodes indicated that the antigen MPB83 of both M. tb and M. bovis were similarly distributed in the tissue samples. Histological examinations showed all of the infected groups exhibited neutrophil infiltration to similar extents. Although the infected cattle did not develop granulomatous inflammation, the metabolic profiles changed significantly, which were characterized by a change in energy production pathways and increased concentrations of N-acetyl glycoproteins. Glycolysis was induced in the infected cattle by decreased glucose and increased lactate content, and enhanced fatty acid β-oxidation was induced by decreased TG content, and decreased gluconeogenesis indicated by the decreased concentration of glucogenic and ketogenic amino acids promoted utilization of substances other than glucose as energy sources. In addition, an increase in acute phase reactive serum glycoproteins, together with neutrophil infiltration and increased of IL-1β production indicated an early inflammatory response before granuloma formation. In conclusion, this study indicated that both M. tb and M.bovis were virulent to cattle. Therefore, it is likely that cattle with M. tb infections would be critical to tuberculosis transmission from cattle to humans. Nuclear magnetic resonance was demonstrated to be an efficient method to systematically evaluate M. tb and M. bovi sinfection in cattle.

    Nutritional approaches are sought to overcome the limits of pioglitazone in metabolic syndrome and non-alcoholic fatty liver disease. Spirulina, a filamentous unicellular alga, reduces serum lipids and blood pressure while exerting antioxidant effects. To determine whether Spirulina may impact macrophages infiltrating the visceral fat in obesity characterizing our metabolic syndrome mouse model induced by the subcutaneous injection treatment of monosodium glutamate. Mice were randomized to receive standard food added with 5% Spirulina, 0.02% pioglitazone, or neither. We tested multiple biochemistry and histology (both liver and visceral fat) readouts at 24 weeks of age. Data demonstrate that both the Spirulina and the pioglitazone groups had significantly lower serum cholesterol and triglyceride levels and liver non-esterified fatty acid compared to untreated mice. Spirulina and pioglitazone were associated with significantly lower leptin and higher levels, respectively, compared to the control group. At liver histology, non-alcoholic fatty liver disease activity score and lipid peroxide were significantly lower in mice treated with Spirulina. Spirulina reduces dyslipidaemia in our metabolic syndrome model while ameliorating visceral adipose tissue macrophages. Human studies are needed to determine whether this safe supplement could prove beneficial in patients with metabolic syndrome. Copyright © 2012 Editrice Gastroenterologica Italiana S.r.l.

    To compare serum concentrations of biomarkers of cartilage and bone metabolism between racehorses with a carpal or metacarpophalangeal or metatarsophalangeal (ie, fetlock) joint injury and matched uninjured control horses, determine changes in biomarker concentrations following joint injury, and establish the biomarkers' diagnostic test performance. 50 Thoroughbred racehorses with a carpal or fetlock joint injury and 50 matched uninjured horses (control horses). Serum concentrations of 2 cartilage synthesis biomarkers (carboxy-terminal propeptide of type II collagen [CPII] and chondroitin sulfate epitope 846 [CS846]), 2 cartilage degradation biomarkers (neoepitope generated by collagenase cleavage of type II collagen [C2C] and cross-linked carboxy-terminal telopeptide fragments of type II collagen [CTX-II]), and serum activity of a bone formation marker (bone-specific alkaline phosphatase [BAP]) were measured around the time of injury diagnosis and monthly thereafter for as long as possible. Injured horses as a group and horses specifically with fetlock joint injuries had significantly lower serum CPII concentrations and significantly higher serum BAP activities than matched control horses. Concentrations of CTX-II were decreased between 2 and 4 months following joint injury. Measurement of CPII concentration at baseline could distinguish between injured horses and control horses with a sensitivity of 82% and specificity of 50%. Although significant differences in specific biomarker concentrations between horses with carpal and fetlock joint injuries and matched control horses were identified, there was no convincing evidence of the suitability of these biomarkers as diagnostic or prognostic tools in a clinical setting.

    2016-09-23

    Untargeted metabolic profiling has generated large activity in the field of clinical biomarker discovery. Yet, no clinically approved metabolite biomarkers have emerged with failure in validation phases often being a reason. To investigate why, we have applied untargeted metabolic profiling in a retrospective cohort of serum samples representing non-related diseases. Age and gender matched samples from patients diagnosed with pneumonia, congestive heart failure, lymphoma and healthy controls were subject to comprehensive metabolic profiling using ultra-performance liquid chromatography-mass spectrometry (UPLC-MS). The metabolic profile of each diagnosis was compared to the healthy control group and significant metabolites were filtered out using t-test with FDR correction. Metabolites found to be significant between each disease and healthy controls were compared and analyzed for overlap. Results show that despite differences in etiology and clinical disease presentation, the fraction of metabolites with an overlap between two or more diseases was 61%. A majority of these metabolites can be associated with immune responses thus representing non-disease specific events. We show that metabolic serum profiles from patients representing non-related diseases display very similar metabolic differences when compared to healthy controls. Many of the metabolites discovered as disease specific in this study have further been associated with other diseases in the literature. Based on our findings we suggest non-related disease controls in metabolomics biomarker discovery studies to increase the chances of a successful validation and future clinical applications.

    Previous works on albinism form of Asinara white donkeys ( Equus asinus ) identified the mutation leading to the peculiar phenotype spread to all specimens of the breed. Inbreeding naturally occurred under geographic isolation, on Asinara Island, in the Mediterranean Sea. Albino individuals can be more susceptible to develop health problems when exposed to natural sun radiation. Alternative metabolic pathways involved in photoprotection were explored in this trial. Nutrition-related metabolites are believed to contribute to the conservation of Asinara donkeys, in which melanin, guaranteeing photoprotection, is lacking. Biochemical profiles with particular focus on blood serum β-carotene and retinol levels were monitored. Identical natural grazing conditions for both Asinara (albino) and Sardo (pigmented) donkey breeds were assured on same natural pastures throughout the experimental period. A comparative metabolic screening, with emphasis on circulating retinol and nutrient-related metabolites between the two breeds, was carried out over one year. Potential intra- and interspecimen fluctuations of metabolites involved in photoprotection were monitored, both during negative and positive photoperiods. Differences ( p  =   .064) between blood serum concentrations of retinol from Asinara versus Sardo breed donkeys (0.630 vs . 0.490 μg/ml, respectively) were found. Retinol levels of blood serum turned out to be similar in the two groups (0.523 vs . 0.493 μg/ml, respectively, p  =   .051) during the negative photoperiod, but markedly differed during the positive one (0.738 vs. 0.486, respectively, p  =   .016). Blood serum β-carotene levels displayed to be constantly around the limit of sensitivity in all animals of both breeds. Variations in blood serum concentrations of retinol in Asinara white donkeys can reflect the need to cope with seasonal exposure to daylight at Mediterranean latitudes, as an alternative to the lack of melanin. These results may

    Serum uric acid level has been suggested to be associated with metabolic syndrome risk factors. However, the association between metabolic syndrome and serum uric acid is still controversial and challenging. This study was aimed to investigate the association between serum uric acid levels and metabolic syndrome components in personnel of the Shahroud University of Medical Sciences. This case-control study was conducted on 499 personnel aged 30-60 years old who were working in Shahroud University of Medical Sciences, in 2015. MetS was defined according to the National Cholesterol Education Program (NCEP) criteria. The relationship between serum UA level and the number of metabolic components was determined by linear regression analysis. In this study, the mean concentration of serum uric acid in men with the syndrome was higher than that in women. Mean serum UA level increased as the number of metabolic factors increased. The mean serum uric acid levels was 4.98±1.64 in patients with metabolic syndrome and 4.5±1.28 in non-patients (p=0.005). Subject with abnormal uric acid were almost 2.62 times more likely than other subject to develop the syndrome. The results of this study showed that only hypertriglyceridemia is a component which increases the risk of hyperuricemia. In addition, hyperuricemia increases the risk of metabolic syndrome by more than two fold. It seems that high uric acid can be considered as a predisposing factor for metabolic syndrome; thus, it is recommended to measure serum uric acid in routine tests. Copyright © 2016 Diabetes India.

    2015-08-01

    Full Text Available Several studies have shown that a poor vitamin D status may increase the risk of developing metabolic syndrome, which leaves the question whether improving one’s vitamin D status may reduce the risk for the syndrome. Here we investigate the effect of temporal changes in serum 25-hydroxyvitamin D (25(OHD concentrations on metabolic syndrome among Canadians enrolled in a preventive health program that promotes vitamin D supplementation. We accessed and analyzed data of 6682 volunteer participants with repeated observations on serum 25(OHD concentrations and metabolic syndrome. We applied logistic regression to quantify the independent contribution of baseline serum 25(OHD and temporal increases in serum 25(OHD to the development of metabolic syndrome. In the first year in the program, participants, on average, increased their serum 25(OHD concentrations by 37 nmol/L. We observed a statistical significant inverse relationship of increases in serum 25(OHD with risk for metabolic syndrome. Relative to those without improvements, those who improved their serum 25(OHD concentrations with less 25 nmol/L, 25 to 50 nmol/L, 50 to 75 nmol/L, and more 75 nmol/L had respectively 0.76, 0.64, 0.59, 0.56 times the risk for metabolic syndrome at follow up. These estimates were independent of the effect of baseline serum 25(OHD concentrations on metabolic syndrome. Improvement of vitamin D status may help reduce the public health burden of metabolic syndrome, and potential subsequent health conditions including type 2 diabetes and cardiovascular disease.

    Several studies have demonstrated a relationship between increased serum uric acid (SUA) concentrations and the prevalence of metabolic syndrome (MetS) in the oriental population. However, to the best of our knowledge, the association between SUA and MetS has never been investigated in elderly European individuals at high cardiovascular risk. The aim of this study was to conduct a cross-sectional and prospective evaluation of the associations between SUA concentrations and the MetS in elderly individuals at high cardiovascular risk. Men and women (55-80 years of age) from different PREDIMED (Prevención con DIeta MEDiterránea) recruiting centers were studied. Baseline cross-sectional (n = 4417) and prospective assessments (n = 1511) were performed. MetS was defined in accordance with the updated harmonized criteria. Anthropometric measurements and biochemical determinations were assessed at baseline and yearly during follow-up. Unadjusted and adjusted regression models were fitted to assess the risk of MetS and its components according to the levels of baseline SUA. Participants in the highest baseline sex-adjusted SUA quartile showed an increased prevalence of MetS than those in the lowest quartile, even after adjusting for potential confounders (odd ratio (OR): 2.3 (95% confidence interval (CI), 1.8-2.8); P < 0.001). Participants in the highest baseline sex-adjusted SUA quartile presented a higher incidence of new-onset MetS than those in the lowest quartile (hazard ratios (HR): 1.4 (95% CI, 1.1-1.9); P < 0.001). Participants initially free at baseline of hypertriglyceridemia (HR: 1.9 (1.6-2.4); P < 0.001), low high-density lipoprotein (HDL)-cholesterol (HR: 1.4 (1.1-1.7); P = 0.002), and hypertension components of MetS (HR: 2.0 (1.2-3.3); P = 0.008) and who were in the upper quartile of SUA had a significantly higher risk of developing these MetS components during follow-up. Elevated SUA concentrations are significantly associated with the development of Met

    Metabolic Syndrome (Mets) and increased serum uric acid (SUA), are well known renal risk predictors and often coexist in patients with type 2 diabetes (T2D). Whether they independently contribute to the onset of CKD is at present unclear. Within the AMD Annals database we identified patients with T2D and normal renal function and urine albumin excretion at baseline and regular follow-up visits during a 4-year period. Blood pressure, BMI, HDL, triglycerides, and SUA were available in 14,267 patients. The association between Mets and/or hyperuricemia (HU, top fifth gender specific quintile) and the occurrence of renal outcomes were evaluated. At baseline 59% of patients (n = 8,408) showed Mets and 18% (n = 2,584) HU. Over the 4-year follow-up, 14% (n = 1,990) developed low eGFR (i.e. below 60 mL/min/1.73 m2), and 26% (n = 3,740) albuminuria. After adjustment for confounders, BP≥130/85, low HDL, triglycerides ≥150 and HU were independently related to the development of low eGFR (1.57, P<0.001; 1.13, P = 0.056; 1.18, P = 0.008; 1.26, P = 0.001) and of albuminuria (1.35, P<0.001; 1.18, P = 0.001; 1.15, P = 0.002; 1.24, P = 0.001), respectively. The incidence of low eGFR was higher in patients with HU independent of the presence or absence of Mets (21%, OR 1.30, p = 0.009 and 20%, 1.57, p<0.000 respectively), while albuminuria occurred more frequently in those with Mets and HU (32%, OR 1.25, p = 0.005) as compared to the reference group. HU and Mets are independent predictors of CKD and its individual components in patients with T2D.

    Some observational studies have suggested that serum uric acid (SUA) levels are one of the determinants of the metabolic syndrome (MetS). However, previous studies reported combined results for men and women after adjusting for sex and few studies take body composition into consideration. Therefore, we performed this sex-specific longitudinal study to investigate how baseline SUA levels influence incident MetS, including body composition as an adjusting factor in a large number of subjects. A total of 14,442 participants (8715 men and 5727 women) participating in a medical health check-up program without diagnosed MetS at baseline were enrolled. Separate analyses were performed for men and women including body composition as a confounding factor. Cox proportional hazards models were used to quantify independent associations between SUA levels and incident MetS. During 63,940person-years of follow-up, there were 4215 (2974 men, 1241 women) incident cases of MetS between 2006 and 2012. After adjustments for age, systolic BP, diastolic BP, BMI, eGFR, smoking status, TG, LDL-C, HDL-C, fasting glucose, and proportion of fat-free mass (100-fat mass, %), the hazard ratios (HR) [95% confidence interval (CI)] for incident MetS comparing the second, the third, and the fourth quartiles to the first quartile of SUA levels were 0.862 (0.770-0.965), 1.102 (0.991-1.225), and 1.246 (1.121-1.385) in men (p for trend<0.001), and 1.045 (0.862-1.266), 1.251 (1.050-1.490), and 1.321 (1.109-1.574) in women (p for trend<0.001), respectively. As a continuous variable, in fully-adjusted models, the HRs (95% CI) for incident MetS associated with each increase of 1mg/dl of SUA levels were 1.094 (1.060-1.130) in men (p<0.001) and 1.148 (1.072-1.228) in women (p<0.001), respectively. We demonstrated that SUA levels are strong and independent predictors of MetS. This relationship remained significant after full adjustments for multiple associated confounders including body composition in both

    To determine the association between the serum concentration of triiodothyronine (T3) with components of metabolic syndrome (MetS), cardiovascular risk (CVR), and diet in euthyroid post-menopausal women without and with MetS. A cross-sectional study was performed in 120 voluntary women of an indigenous population from Tlaxcala-México. Euthyroid status was assessed measuring the serum concentration of thyrotropin (TSH) and thyroid hormones, while that of estradiol was measured to confirm the postmenopausal condition. MetS was diagnosed using the American Heart Association/National Heart, Lung, and Blood Institute Scientific Statement (AHA/NHLBI) criterion. Estimation of CVR was calculated based on the Framingham scale. Diet components were evaluated based on survey applications. Correlations, logistic regression analyses, ANOVA or Kruskall-Wallis, and chi-square tests were used to determine significant differences (P ≤ 0.05) between women without MetS and women with MetS having different serum concentrations of T3. Triiodothyronine was positively correlated with insulin but negatively correlated with glucose, high-density lipoprotein cholesterol (HDL-C), and CVR. Compared to women without MetS, women with MetS and low-normal T3 concentration showed a high risk for hyperglycemia and moderate/high risk for CVR. In contrast, a high-normal T3 concentration increased the risk to have a big waist circumference, a high concentration of HDL-C, and insulin resistance. Diet analysis showed a high grade of malnutrition in women from all groups. The intake of calories was positively affected by the T3 concentration, albeit it did not affect the extent of malnutrition. In contrast to concentrations of TSH, total thyroxin (T4), and free T4, the concentration of serum T3 was strongly correlated with cardio-metabolic variables in euthyroid postmenopausal women. In comparison to women without MetS, a high-normal serum concentration of T3 in women with MetS is positively

    We studied the combined effects of wholegrain, fish and bilberries on serum metabolic profile and lipid transfer protein activities in subjects with the metabolic syndrome. Altogether 131 subjects (40-70 y, BMI 26-39 kg/m(2)) with impaired glucose metabolism and features of the metabolic syndrome were randomized into three groups with 12-week periods according to a parallel study design. They consumed either: a) wholegrain and low postprandial insulin response grain products, fatty fish 3 times a week, and bilberries 3 portions per day (HealthyDiet), b) wholegrain and low postprandial insulin response grain products (WGED), or c) refined wheat breads as cereal products (Control). Altogether 106 subjects completed the study. Serum metabolic profile was studied using an NMR-based platform providing information on lipoprotein subclasses and lipids as well as low-molecular-weight metabolites. There were no significant differences in clinical characteristics between the groups at baseline or at the end of the intervention. Mixed model analyses revealed significant changes in lipid metabolites in the HealthyDiet group during the intervention compared to the Control group. All changes reflected increased polyunsaturation in plasma fatty acids, especially in n-3 PUFAs, while n-6 and n-7 fatty acids decreased. According to tertiles of changes in fish intake, a greater increase of fish intake was associated with increased concentration of large HDL particles, larger average diameter of HDL particles, and increased concentrations of large HDL lipid components, even though total levels of HDL cholesterol remained stable. The results suggest that consumption of diet rich in whole grain, bilberries and especially fatty fish causes changes in HDL particles shifting their subclass distribution toward larger particles. These changes may be related to known protective functions of HDL such as reverse cholesterol transport and could partly explain the known protective effects of fish

    Full Text Available Buruli ulcer is a skin disease caused by Mycobacterium ulcerans that is spreading in tropical countries, with major public health and economic implications in West Africa. Multi-analyte profiling of serum proteins in patients and endemic controls revealed that Buruli ulcer disease down-regulates the circulating levels of a large array of inflammatory mediators, without impacting on the leukocyte composition of peripheral blood. Notably, several proteins contributing to acute phase reaction, lipid metabolism, coagulation and tissue remodelling were also impacted. Their down-regulation was selective and persisted after the elimination of bacteria with antibiotic therapy. It involved proteins with various functions and origins, suggesting that M. ulcerans infection causes global and chronic defects in the host's protein metabolism. Accordingly, patients had reduced levels of total serum proteins and blood urea, in the absence of signs of malnutrition, or functional failure of liver or kidney. Interestingly, slow healers had deeper metabolic and coagulation defects at the start of antibiotic therapy. In addition to providing novel insight into Buruli ulcer pathogenesis, our study therefore identifies a unique proteomic signature for this disease.

    Full Text Available Background: The simultaneous occurrence of risk factors for both type II diabetes and coronary artery disease show the existence of "metabolic syndrome".The studies have been shown that vitamin D deficiency has an inverse correlation with the components of metabolic syndrome such as BMI,systolic blood pressure,waist,fatsing blood glucose,LDL cholesterol and insulin resistance. So, this sudy evaluated the association between metabolic syndrome and vitamin D deficiency. Materials and Methods: In this cross – sectional study among overweight patients referred to private and public clinics,70 patients with metabolic syndrome based on ATPIII criteria and 70 overweight healthy participants were selected and mean of 25 hydroxyvitamin D level in the two groups were compared. Laboratory tests for lipid profile and fasting blood glucose and vitamin D level and also examinations for waist, weight,height were done. Mann-Whitney-U and Student-t-test were used to evaluate the relationship of vitamin D level and metabolic syndrome. Results: Participants in this study were 63% female.The prevalence of vitamin D deficiency was 71.4% and 26.2% in metabolic and control groups, respectively (P 0.001. Mean of vitamin D was 20±22 and 27±17 ng / ml in metabolic and control groups respectively (P 0.01. Conclusion: The findings showed a significant correlation between vitamin D deficiency and metabolic syndrome and vitamin D deficiency has a role in establishment of metabolic syndrome through different mechanisms.

    Proton nuclear magnetic resonance (NMR)-based metabolic phenotyping of urine and blood plasma/serum samples provides important prognostic and diagnostic information and permits monitoring of disease progression in an objective manner. Much effort has been made in recent years to develop NMR instrumentation and technology to allow the acquisition of data in an effective, reproducible, and high-throughput approach that allows the study of general population samples from epidemiological collections for biomarkers of disease risk. The challenge remains to develop highly reproducible methods and standardized protocols that minimize technical or experimental bias, allowing realistic interlaboratory comparisons of subtle biomarker information. Here we present a detailed set of updated protocols that carefully consider major experimental conditions, including sample preparation, spectrometer parameters, NMR pulse sequences, throughput, reproducibility, quality control, and resolution. These results provide an experimental platform that facilitates NMR spectroscopy usage across different large cohorts of biofluid samples, enabling integration of global metabolic profiling that is a prerequisite for personalized healthcare.

    Hyperuricemia is known to be associated with various metabolic abnormalities of the metabolic syndrome, but its precise contribution is not well defined. We have investigated the effects of serum uric acid on the metabolic syndrome as defined by the Adult Treatment Panel (ATP) III criteria and tested its independent association. This was a cross-sectional study consisting of 1686 Korean subjects (821 men and 865 women) from a health promotion center. Clinical data and the presence of the metabolic syndrome were assessed, and serum uric acid was tested for its independent contribution to the metabolic syndrome using 2 multiple logistic regression models. The metabolic syndrome was defined by the original ATP III criteria and the modified ATP III criteria that include a reduced waist circumference. The general age-adjusted prevalence of the metabolic syndrome was 4.4% in men and 6.8% in women; hyperuricemic subjects tended to have a higher prevalence of the metabolic syndrome and more metabolic abnormalities than normouricemic subjects. The prevalence of the metabolic syndrome increased as normouricemia (2.9%) progressed to hyperuricemia (8.9%) and to gout (43.6%) in men. Multivariate analysis showed that serum uric acid was a significant factor for the development of the metabolic syndrome as defined by the original ATP III criteria only in one model for women (odds ratio, 1.51; 95% confidence interval, 1.11-2.05; P = .009). Serum uric acid is closely linked to and may even be independently associated with the metabolic syndrome as defined by the ATP III criteria, but only in women.

    Full Text Available BACKGROUND: Studies on the combined associations of elevated serum hepatic enzyme activity and alcohol drinking with metabolic syndrome are rare. Our objectives were to evaluate the associations of elevated serum hepatic enzyme activity with the prevalence of metabolic syndrome in the general Japanese population and whether alcohol drinking had a modifying effect on these associations. METHODS: We conducted a cross-sectional study with 1,027 men and 1,152 women throughout Japan during 2002-2010. Biochemical factors including alanine aminotransferase (ALT and gamma-glutamyl transferase (GGT were determined in overnight fasting blood, and a survey on lifestyle was conducted by questionnaire. Serum ALT and GGT levels were divided into tertiles in men and women, and their associations with the prevalence of metabolic syndrome were evaluated by logistic regressions. RESULTS: Elevated serum ALT and GGT, even within the reference range, were independently associated with increased metabolic syndrome prevalence and were associated with most of its components in both sexes, except for the association between GGT and low high-density lipoprotein (HDL cholesterol in men. Stratified analyses by alcohol drinking status revealed that within the same tertile category of serum ALT and GGT, subjects classified as alcohol abstainers showed higher adjusted odds ratios for metabolic syndrome prevalence than those classified as regular alcohol drinkers in both sexes. The interaction effects of serum GGT with alcohol drinking status on metabolic syndrome prevalence were significant in both sexes. CONCLUSIONS: These results suggest that elevated serum ALT and GGT, even within the reference range, are independently associated with increased metabolic syndrome prevalence, especially in alcohol abstainers, in Japanese men and women.

    Full Text Available Background: Polycystic ovary syndrome (PCOS patients are more prone to abnormalproduction of some regulatory peptides. In these patients, studies on the serum levels ofleptin and ghrelin are controversial. This study aims to investigate serum levels of leptinand ghrelin and their correlation with metabolic and endocrine indices in PCOS.Materials and Methods: This case-control study was conducted on 60 women; 30 withPCOS and 30 healthy women whose age and body mass index (BMI were matched and whowere referred to Alzahra Hospital, Tabriz, Iran. Serum levels of leptin, ghrelin, insulin, luteinizinghormone (LH, follicle stimulating hormone (FSH, sex hormone-binding globulin(SHBG, and testosterone were measured. The homeostasis model assessment of insulin resistance(HOMA-IR was calculated. Descriptive statistics and correlations were performed usingSPSS 12.0 for Windows.Results: In PCOS women, serum levels of leptin, insulin, HOMA-IR, testosterone, LH,and LH/FSH were significantly higher, while SHBG was lower than in healthy women.Ghrelin and FSH were similar in both groups. Serum levels of leptin correlated with BMI(r=0.85, p<0.001, waist to hip ratio (WHR (r=0.55, p<0.01, insulin levels (r=0.85,p<0.001 and HOMA-IR (r=0.67, p<0.01, while ghrelin levels had an inverse associationwith testosterone (r=-0.32, p=0.04.Conclusion: The results showed increased leptin levels while ghrelin remained unchangedin PCOS patients. In PCOS patients, leptin positively correlated with BMI,WHR, insulin, and insulin resistance, while ghrelin was only associated with serumtestosterone levels.

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

    Mature weight and rate of maturing were estimated in 177 Angus, Brahman, and reciprocal-cross cows grazing bermudagrass or endophyte-infected tall fescue over a 4-yr period to evaluate genotype x environment interactions. Data were collected every 28 d until cows were approximately 18 mo of age and then at prebreeding, postcalving, and weaning of calf. All cows with weight data to at least 42 mo of age were included in the analysis. Mature weight and rate of maturing were estimated using the three-parameter growth curve model described by Brody (1945). Data were pooled over year and analyzed by the general linear model procedure of SAS. Included in the models for mature weight and rate of maturing were the independent variables of genotype, environment, and genotype x environment interaction. There was a genotype x environment interaction (P pastures had greater (P < 0.01) mean mature BW than Angus x Brahman cows grazing bermudagrass (611 +/- 17 vs 546 +/- 16 kg). Angus x Brahman cows grazing bermudagrass had lower (P < 0.05) mean mature BW than Brahman x Angus cows grazing bermudagrass or endophyte-infected fescue and Brahman cows grazing bermudagrass (546 +/- 16 vs 624 +/- 19, 614 +/- 22 and 598 +/- 20 kg, respectively). Brahman cows grazing endophyte-infected fescue had smaller (P < 0.05) mean mature BW than all genotype x forage combinations except for Angus x Brahman cows grazing bermudagrass. Angus cows had a smaller (P < 0.05) mean rate of maturing than Angus x Brahman and Brahman x Angus cows (0.039 +/- 0.002 vs 0.054 +/- 0.002 and 0.049 +/- 0.002%/mo, respectively), respectively, and Angus x Brahman cows had a larger (P < 0.05) mean rate of maturing than Brahman x Angus and Brahman cows (0.054 +/- 0.002 vs 0.049 +/- 0.002 and 0.041 +/- 0.002 %/mo, respectively). There was a direct breed x forage interaction (P < 0.05) for mature BW. These data suggest that the choice of breed type is important in maintaining a crossbreeding program, in that mature BW and

    Full Text Available This experiment was conducted to study effects of vitamin E supplementation on physical, chemical and eating quality of longissimus dorsi muscle of Brahman x Thai native cattle. Four groups of three Brahman x Thai native steers, weighing 150-160 kg, were fed with concentrate supplemented with vitamin E at 0, 100, 200, 400 ppm before and after grazing in the pasture. The experiment lasted 120 days. At the end of the feeding trial all cattle were slaughtered and longissimus dorsi muscles were collected to determine various meat quality aspects. The results showed that the lowest shear force value of meat in the 400-ppm group indicated a more tender in comparison to the others. All supplementation levels had no effect on pH of the meat. Water holding capacity of the meat (after chilled for 24 hours from the 100-ppm group, was significantly different (P0.05 either triobarbituric acid (TBA value or eating quality (tenderness, juiciness, flavor and overall acceptability.

    To determine breed differences in ovarian function and endocrine secretion, daily rectal ultrasonography was conducted on multiparous lactating Angus (temperate Bos taurus; n = 12), Brahman (tropical Bos indicus; n = 12), and Senepol (tropical Bos taurus; n = 12) cows during an estrous cycle in summer. Blood was collected daily to quantify plasma concentrations of FSH, LH, progesterone, estradiol, GH, insulin-like growth factor (IGF)-I, IGF-II, IGF binding proteins (IGFBP), insulin, glucose, and plasma urea nitrogen (PUN). Numbers of small (2 to 5 mm), medium (6 to 8 mm), and large follicles (> or = 9 mm) were greater (P Senepol cows. Length of the estrous cycle (SEM = .6 d) was similar (P > .10) among Senepol (20.4 d), Angus (19.5 d), and Brahman (19.7 d) cows. Senepol cows had greater (P Senepol cows (breed x day, P .10) among breeds. Concentrations of GH, IGF-I, insulin, and PUN were greater (P Senepol cows. Plasma glucose concentrations were greater (P Senepol than in Brahman or Angus cows. In conclusion, Brahman (Bos indicus) and Senepol cows (tropical Bos taurus) had greater numbers of follicles in all size categories and greater diameter of CL than Angus (temperate Bos taurus) cows. These ovarian differences may be due to changes in the pattern of secretion of FSH, insulin, IGF-I, and GH but not LH, IGF-II, or IGFBP-2 or -3.

    Serum is a common sample of convenience for metabolomics studies. Its processing time can be lengthy and may result in the loss of metabolites including those of red blood cells (RBC). Unlike serum, whole blood (WB) is quickly processed, minimizing the influence of variable hemolysis while including RBC metabolites. To determine differences between serum and WB metabolomes, both sample types, collected from healthy volunteers, were assayed by 1H-NMR spectroscopy. A total of 34 and 50 aqueous metabolites were quantified from serum and WB, respectively. Free hemoglobin (Hgb) levels in serum were measured and the correlation between Hgb and metabolite concentrations was determined. All metabolites detected in serum were at higher concentrations in WB with the exception of acetoacetate and propylene glycol. The 18 unique metabolites of WB included adenosine, AMP, ADP and ATP, which are associated with RBC metabolism. The use of serum results in the underrepresentation of a number of metabolic pathways including branched chain amino acid degradation and glycolysis and gluconeogenesis. The range of free Hgb in serum was 0.03-0.01 g/dL and 8 metabolites were associated (p ≤ 0.05) with free Hgb. The range of free Hgb in serum samples from 18 sepsis patients was 0.02-0.46 g/dL. WB and serum have unique aqueous metabolite profiles but the use of serum may introduce potential pathway bias. Use of WB for metabolomics may be particularly important for studies in diseases like sepsis in which RBC metabolism is altered and mechanical and sepsis-induced hemolysis contributes to variance in the metabolome.

Sixty-two PCOS and ninety normal cycling (NC females with matched age and body mass index (BMI were recruited for this cross-sectional study. Serum leptin, FSH, LH, E2, free testosterone, progesterone, thyroid profile, and FBG levels were measured. The mean leptin levels in PCOS and NC were not significantly different (45.56 ng/mL ± 1.49 vs 41.78 ± 1.31 ng/mL, P>0.05; however, leptin levels showed a strong correlation with BMI in PCOS and NC group (r=0.77, P<0.0001; r=0.82, P<0.0001, resp.. High E2 levels in NC had a significant correlation with leptin whereas FBG correlated with leptin in PCOS (r=0.51, P=0.005. TSH had a substantial correlation (r=0.49, P<0.005; r=0.69, P<0.005 in PCOS and NC, respectively. There was no significant difference found in circulating leptin concentration between PCOS and NC subjects. Leptin levels in PCOS were related with metabolic impairments manifested by disturbance in FBG levels and impairment of reproductive functions in terms of reduced E2 secretion.

    Congenital scoliosis (CS) is a three-dimensional deformity of the spine affecting quality of life. We have demonstrated TBX6 haploinsufficiency is the most important contributor to CS. However, the pathophysiology at the protein level remains unclear. Therefore, this study was to explore the differential proteome in serum of CS patients with TBX6 haploinsufficiency. Sera from nine CS patients with TBX6 haploinsufficiency and nine age- and gender-matched healthy controls were collected and analysed by isobaric tagged relative and absolute quantification (iTRAQ) labelling coupled with mass spectrometry (MS). In total, 277 proteins were detected and 20 proteins were designated as differentially expressed proteins, which were submitted to subsequent bioinformatics analysis. Gene Ontology classification analysis showed the biological process was primarily related to 'cellular process', molecular function 'structural molecule activity' and cellular component 'extracellular region'. IPA analysis revealed 'LXR/RXR activation' was the top pathway, which is a crucial pathway in lipid metabolism. Hierarchical clustering analysis generated two clusters. In summary, this study is the first proteomic research to delineate the total and differential serum proteins in TBX6 haploinsufficiency-caused CS. The proteins discovered in this experiment may serve as potential biomarkers for CS, and lipid metabolism might play important roles in the pathogenesis of CS. © 2017 The Authors.

    The aim of this study was to assess the effect of vegetarian diet on iron metabolism parameters paying special attention to serum hepcidin and soluble transferrin receptor (sTfR) concentrations in 43 prepubertal children (age range 4.5-9.0 years) on vegetarian and in 46 children on omnivorous diets. There were no significant differences according to age, weight, height, and body mass index (BMI) between vegetarian and omnivorous children. Vegetarians had similar intake of iron and vitamin B 12 and a significantly higher intake of vitamin C (p vegetarians. Hematologic parameters and serum iron concentrations were within the reference range in both groups of children. Serum transferrin levels were similar in all subjects; however, ferritin concentrations were significantly (p vegetarians than in omnivores. In children on a vegetarian diet, median hepcidin levels were lower (p vegetarians. We did not find significant associations with concentration of sTfR and selected biochemical, anthropometric, and dietary parameters in any of the studied groups of children. As hematologic parameters and iron concentrations in vegetarians and omnivores were comparable and ferritin level was lower in vegetarians, we suggest that inclusion of novel markers, in particular sTfR (not cofounded by inflammation) and hepcidin, can better detect subclinical iron deficiency in children following vegetarian diets.

    Full Text Available Human serum paraoxonase contributes to the anti-atherogenic effect of high-density lipoprotein cholesterol (HDL-C and has been shown to protect both low-density lipoprotein cholesterol (LDL-C and HDL-C against lipid peroxidation. We investigated the effects of rosiglitazone on paraoxonase activity and metabolic parameters in patients with type 2 diabetes mellitus [50 patients (30 males, 20 females; mean±SD age: 58.7±9.2 years, body mass index: 28.2±4.1 kg/m2], in whom glucose control could not be achieved despite treatment with metformin, sulphonylurea, and/or insulin. The patients were given 4 mg/day rosiglitazone for 3 months in addition to their usual treatment. Serum paraoxonase activity, malondialdehyde, homocysteine, and lipid profile were measured at the time of initiation and at the end of therapy with rosiglitazone. After rosiglitazone therapy, serum levels of HDL-C, apolipoprotein A-1, and paraoxonase activity increased significantly (P

    Our aim was to study whether there is causal association between serum uric acid and metabolic syndrome (MetS). A cross-sectional study was performed, including a total of 27,009 subjects (23,345 subjects having uric acid data) from the Dongfeng-Tongji Cohort study. The MetS was defined by the International Diabetes Foundation criteria of 2005. Association analysis was performed by logistic regression. A genetic risk score was calculated by adding the uric acid increasing alleles in two SNPs (rs11722228 in SLC2A9 and rs2231142 in ABCG2) which were identified from our genome-wide association study on uric acid levels. The causal association was examined by mendelian randomization analysis. Among a middle- and old-age Chinese population, serum uric acid concentrations were strongly associated with the risk of MetS and its several components (P uric acid effects. Each additional uric acid increasing allele in the genetic risk score was associated with 3 % increased MetS risk (OR = 1.03, 95 % CI 0.98-1.09; P = 0.23). Further adjustment for serum uric acid attenuated the trend of individual SNP and genetic risk score with increased MetS risk (all OR uric acid was associated with MetS risk in a middle- and old-age Chinese population. Whether this association was causal remained to be investigated in the future studies.

    The present study has investigated the ability of amitraz, a widely used formamidine pesticide, to modulate serum concentrations and liver microsomal metabolism of 17{beta}-estradiol (E2) and testosterone in rats. Amitraz was administered intraperitoneally to male rats for 4 days and to intact female rats or ovariectomized (OVX) and 0.5 mg/kg E2-supplemented female rats for 7 days. E2 and metabolites were analyzed by gas chromatography-electron capture detection and testosterone and metabolites were analyzed by high-pressure liquid chromatography. In OVX and E2-supplemented females, 50 mg/kg amitraz caused an 85% decrease of serum E2 concentration and a marked increase of 2-OH-E2 concentration. Amitraz at 25 and 50 mg/kg produced 9.0-fold or greater increases of serum testosterone and 2{beta}-OH-testosterone levels in males. Amitraz at 25 mg/kg resulted in no or minimal increases of liver microsomal formation of E2 or testosterone metabolites. Amitraz at 50 mg/kg produced 1.4- to 3.6-fold increases of 2-OH-E2; estrone; 2{beta}-, 6{beta}-, and 16{alpha}-OH-testosterone; and androstenedione formation in males and intact females. Amitraz at 50 mg/kg preferentially increased intact female 16{beta}-OH-testosterone production by 8.6-fold. In OVX females, E2 supplement alone or cotreatment with E2 and 50 mg/kg amitraz produced 1.3- to several-fold increases of 2- and 4-OH-E2 formation and 2{beta}- and 16{alpha}-OH-testosterone production. The cotreatment increased 6{beta}- and 16{beta}-OH-testosterone formation by 1.8- and 1.6-fold, respectively. The present findings show that amitraz induces hepatic E2 and testosterone metabolism in male and female rats, decreases serum E2 concentration in OVX and E2-supplemented females, but increases serum testosterone in males.

    To determine the maternal and reproductive performance of F1 cows in the subtropics, 42 Brahman x Angus, 34 Senepol x Angus, and 50 Tuli x Angus cows were bred to Angus bulls to calve first and subsequently bred to Charolais bulls to calve as 3- to 8-yr-olds. Age at first calving did not differ among crossbred cows. Angus-sired calf birth weights were heavier (P Senepol x Angus than either Brahman x Angus or Tuli x Angus cows. Weaning weights of Angus-sired calves were heavier (P Senepol x Angus (194.9 kg) or Tuli x Angus (191.5 kg) cows. As 3- to 8-yr-old cows, calf birth weights were heavier (P Senepol x Angus compared with Brahman x Angus but not Tuli x Angus cows. Weaning weights of Charolais-sired calves were heaviest (P Senepol x Angus cows (245.0 kg). Calf crop born and calf crop weaned were lowest (P Senepol x Angus cows (76.9 and 70.2%) and did not differ between Brahman x Angus (89.0 and 86.1%) and Tuli x Angus (94.7 and 86.5%) cows. Tuli x Angus cows tended (P Senepol x Angus cows. As 3- to 8-yr-olds, weaning weight per cow exposed was greatest (P Senepol x Angus (173.0 kg), and intermediate (P Senepol x Angus cows (33.8). These data indicate that, in the subtropics, maternal and reproductive performance of Tuli x Angus cows, but not Senepol x Angus cows, was comparable to Brahman x Angus cows, except for lower calf survivability and weaning weight.

    Full Text Available Serum GM3 molecular species were quantified in 125 Japanese residents using tandem mass spectrometry multiple reaction monitoring. Individuals were categorized by the presence or absence of metabolic disease risk factors including visceral fat accumulation, hyperglycemia and dyslipidemia. A total of 23 GM3 molecular species were measured, of these, eight were found to be significantly elevated in individuals with visceral fat accumulation and metabolic disease, defined as the presence of hyperglycemia and dyslipidemia. All of the GM3 molecular species were composed of the sphingoid base sphingosine (d18:1 (Δ4 and, interestingly, six of the eight elevated GM3 molecular species contained a hydroxylated ceramide moiety. The hydroxylated GM3 species were, in order of decreasing abundance, d18:1-h24:0 ≈ d18:1-h24:1 > d18:1-h22:0 » d18:1-h20:0 > d18:1-h21:0 > d18:1-h18:1. Univariate and multiple linear regression analyses were conducted using a number of clinical health variables associated with obesity, type 2 diabetes, metabolic disease, atherosclerosis and hypertension. GM3(d18:1-h24:1 was identified as the best candidate for metabolic screening, proving to be significantly correlated with intima-media thickness, used for the detection of atherosclerotic disease in humans, and a number of metabolic disease risk factors including autotaxin, LDL-c and homeostatic model assessment insulin resistance (HOMA-IR.

    We explored the association between serum uric acid (SUA) and metabolic syndrome (MetS) in Chinese rural adults. A total of 16,577 subjects (6354 men and 10,223 women) were from the RuralDiab study. SUA concentration was measured by the enzymatic colorimetric method. A meta-analysis including 12 eligible studies focused on SUA and MetS was preformed to confirm the findings of the cross-sectional study. After adjustment for age, educational level, and other covariates, the odds ratio (ORs) for MetS increased smoothly with the increasing SUA concentration in both sexes (P for no-linear trend > 0.05). The adjusted ORs of MetS comparing the fourth and firstly quartiles were 3.11 [95% CI: 2.58-3.74] in men and 3.64 [95% CI: 3.22-4.11] in women (P trend  uric acid and metabolic syndrome, but evidence on the strength and consistency of the association remains uncertain and limited, especially in rural population. In addition, the epidemiological research and meta-analysis on the association have not been reported. WHAT DOES THIS STUDY ADD?: The results of this study showed that serum uric acid was significantly associated with metabolic syndrome and its components in Chinese rural population. Furthermore, the findings demonstrated that the significant associations varied across sex. In addition, the results of epidemiological research were similar with the meta-analysis, which demonstrates the credible of the results of the epidemiology research. Copyright © 2018 Elsevier B.V.

    Nesfatin-1, a recently discovered anorexigenic neuropeptide, is expressed in several tissues including pancreatic islet cells and central nervous system. This peptide seems to play an important role in hypothalamic pathways regulating food intake and energy homeostasis. We aimed to investigate the relation of serum nesfatin-1 level with metabolic and anthropometric parameters in obese children. The study included obese children with a body mass index (BMI) above the 95th percentile and healthy children with a BMI below the 85th percentile. The healthy and obese subjects had similar age and gender distribution. Fasting serum glucose, insulin, lipid profile, and nesfatin-1 levels were measured to evaluate metabolic parameters. Obese group (n = 37) had significantly higher BMI, BMI-SDS (standard deviation score of BMI), triglyceride, insulin, and insulin resistance index by the homeostasis model assessment, systolic and diastolic blood pressure values compared with the control group (n = 31) (p obese subjects was significantly lower than that of the control subjects (p = 0.001). No statistically significant difference was found when nesfatin-1 levels were compared among obese patients regarding the presence of insulin resistance (p = 0.202). In the obese group, nesfatin-1 level was negatively correlated with BMI-SDS, but not with insulin resistance index (p = 0.02 and p = 0.361, respectively). This is the first study to evaluate nesfatin-1 levels in relation with anthropometric and metabolic parameters in obese patients who had significantly lower nesfatin-1 levels. Our results underline that nesfatin-1 may play an important role in regulation of food intake in obese individuals. © 2013 John Wiley & Sons A/S.

    The petroleum ether fraction of Bupleuri Radix which is contained in the traditional Chinese medicine prescription of Xiaoyaosan (XYS) may have a therapeutic effect in depressed subjects based on the results of our previous study. It has been reported that Bupleuri Radix can cause liver toxicity following overdosing or long-term use. Therefore, this study aimed to decipher the differential effective and toxic responses of Bupleuri Radix in chronic unpredictable mild stress (CUMS) (with depression) and healthy rats based on serum metabolic profiles. Serum metabolic profiles were obtained using the UHPLC- Q Exactive Orbitrap-MS technique. Our results demonstrated that the petroleum ether fraction of Bupleuri Radix (PBR) produces an antidepressant effect through regulating glycometabolism, amino acid metabolism, sphingolipid metabolism, glycerophospholipid metabolism, and fatty acid metabolism. It also induces more severe toxic reactions in the liver or kidney in healthy rats than in CUMS rats, which exhibited a comparatively mild drug-induced toxic reaction. The altered lysine degradation, sphingolipid metabolism, glycerophospholipid metabolism, fatty acid metabolism, and bile acid metabolism could be at least partly responsible for the PBR toxic responses in healthy rats. The differential effective and toxic response of PBR in CUMS rats and healthy rats provide a new standard for the more rational and safer application of clinical drugs in the future. PMID:29379441

    Organochlorine pesticides (OCPs) have been linked to adult metabolic disorders; however, few studies have examined these associations in childhood. We prospectively evaluated the associations of baseline serum OCPs (hexachlorobenzene, β-hexachlorocyclohexane, and p,p′-dichlorodiphenyldichloroethylene) in Russian boys with subsequent repeated measurements of serum glucose, insulin, lipids, leptin, and calculated homeostatic model assessment of insulin resistance (IR). During 2003–2005, we enrolled 499 boys aged 8–9 years in a prospective cohort; 318 had baseline serum OCPs and serum biomarkers measured at ages 10–13 years. Multivariable generalized estimating equation and mediation regression models were used to examine associations and direct and indirect (via body mass index (BMI) (weight (kg)/height (m)2)) effects of prepubertal OCP tertiles and quintiles with biomarkers. In multivariable models, higher p,p′-dichlorodiphenyldichloroethylene (quintile 5 vs. quintile 1) was associated with lower leptin, with relative mean decreases of 61.8% (95% confidence interval: 48.4%, 71.7%) in models unadjusted for BMI and 22.2% (95% confidence interval: 7.1%, 34.9%) in models adjusted for BMI; the direct effect of p,p′-dichlorodiphenyldichloroethylene on leptin accounted for 27% of the total effect. IR prevalence was 6.6% at ages 12–13 years. Higher hexachlorobenzene (tertile 3 vs. tertile 1) was associated with higher odds of IR in models adjusted for BMI (odds ratio = 4.37, 95% confidence interval: 1.44, 13.28). These results suggest that childhood OCPs may be associated with IR and lower leptin. PMID:25255811

    In the present study, we evaluated and compared serum markers of bone turnover in dialyzed patients with serum intact parathyroid hormone (iPTH) MIX group, n = 6), and iPTH > 150 pg/mL (non-LBT group, n = 15). Laboratory parameters included iPTH; cyclase activating parathyroid hormone (CAP); osteoprotegerin (OPG); OPG ligand (OPGL); inorganic phosphates; total Ca, urea, and creatinine; alkaline phosphatase activity; and blood pH. Cyclase inactive parathyroid hormone (CIP) was calculated by subtraction of CAP from iPTH. When results were adjusted for sex, age, dialysis modality, and dialysis duration, only CAP and CIP were significantly different between the groups. For the LBT MIX, and non-LBT groups respectively, mean serum values for CAP were 20.3 pg/mL (range: 6.53-50.7 pg/mL), 79.3 pg/mL (range: 53.4-99.0 pg/mL), and 343.3 pg/mL (range: 102.1-887.9 pg/mL) and for CIP they were 7.74 pg/mL (range: 2.41-48.4 pg/mL), 50.2 pg/mL (range: 29.5-68.0 pg/mL), and 129.0 pg/mL (range: 62.4-399.0 pg/mL). In a selection of dialyzed patients, serum CAP and CIP concentrations--but not CAP/CIP ratio, OPG, OPGL, and OPGL/OPG ratio--can, like iPTH values, be used to categorize those suspected of having adynamic bone.

    To further our understanding of the pathogenesis of chondromalacia of the patella (CM), we have studied the release into knee joint fluid and serum, obtained from patients with CM, of molecules associated with the metabolism of joint cartilage matrix and synovium. Interleukin-1 alpha (IL-1 alpha), interleukin-1 beta (IL-1 beta), interleukin-6 (IL-6), stromelysin-1 (MMP-3), interstitial collagenase (MMP-1), tissue inhibitor for metalloproteinases-1 (TIMP-1), phospholipase activity A2 (PLA2), hyaluronan (HA), aggrecan fragments (AGN) and antigenic keratan sulfate (KS) were quantified in knee joint lavage fluid from 96 patients with CM; KS and HA also was measured in serum. Chondromalacia was graded on a scale of I to IV according to Outerbridge (1961). The histopathology of the synovial membrane close to the patellofemoral joint was evaluated. Control samples were obtained from nine patients with knee pain presenting with arthroscopically normal knee joints. The concentrations of MMP-3, MMP-1 and TIMP-1 proteins in joint lavage fluid were increased in advanced (grade IV) CM, compared with controls. Levels of MMP-1 in lavage fluid correlated with the severity of CM (r = 0.38, P < 0.01) and MMP-1 and MMP-3 concentrations correlated with each other (r = 0.45, P < 0.001). TIMP-1 was elevated in grade IV CM compared with grades II and III CM (P < 0.02, P < 0.01). Interleukins (IL-1 alpha, IL-1 beta and IL-6) showed no significant change in CM. The lavage fluid level of PLA2 increased with the severity of CM (r = 0.40, P < 0.001). Serum KS was higher in CM IV than in controls (P = 0.05), while lavage fluid KS concentration was elevated in CM I (P = 0.04). There were no differences in the lavage fluid levels of AGN and HA between the different study groups. Synovium showed slight or moderate histological signs of inflammation in 9% of CM patients. The changes in the release and activity of these marker molecules from serum and synovial fluid may reflect changes in the

    Data from 2 previously published experiments, New South Wales (NSW; n = 161) and Western Australia (WA; n = 135), were used to test molecular value predictions (MVP), generated from commercially available gene markers, on economically important traits of Bos indicus (Brahman) cattle. Favorable tenderness MVP scores were associated with reduced shear force values of strip loin (LM) steaks aged 7 d from Achilles-hung carcasses (P ≤ 0.06), as well as steaks aged 1 (P ≤ 0.08) or 7 d (P ≤ 0.07) from carcasses hung from the pelvis (tenderstretch). Favorable tenderness MVP scores were also associated with improved consumer tenderness ratings for strip loin steaks aged 7 d and either Achilles hung (P ≤ 0.006) or tenderstretched (P ≤ 0.07). Similar results were observed in NSW for rump (top butt; gluteus medius) steaks, with favorable tenderness MVP scores associated with more tender (P = 0.006) and acceptable (P = 0.008) beef. Favorable marbling MVP scores were associated with improved (P ≤ 0.021) marbling scores and intramuscular fat (IMF) content in the NSW experiment, despite low variation in marbling in the Brahman cattle. For the WA experiment, however, there were no (P ≥ 0.71) relationships between marbling MVP and marbling scores or IMF content. Although residual (net) feed intake (RFI) was not associated (P = 0.63) with the RFI (feed efficiency) MVP, the RFI MVP was adversely associated with LM tenderness and acceptability of 7-d-aged Achilles-hung carcasses in NSW (P ≤ 0.031) and WA (P ≤ 0.037). Some other relationships and trends were noted between the MVP and the other traits, but few reached statistical significance, and none were evident in both experiments. Results from this study provide evidence to support the use of the tenderness MVP. The value of the marbling MVP, which was associated with marbling in only 1 herd, warrants further evaluation; however, there appears to be no evidence to support use of the RFI MVP in Brahman cattle.

    Background: Berries are associated with health benefits. Little is known about the effect of baseline metabolome on the overall metabolic responses to berry intake. Objective: We studied the effects of berries on serum metabolome. Design: Eighty overweight women completed this randomized crossover study. During the interventions of 30 d, subjects consumed dried sea buckthorn berries (SBs), sea buckthorn oil (SBo), sea buckthorn phenolics ethanol extract mixed with maltodextrin (SBe+MD) (1:1), or frozen bilberries. Metabolic profiles were quantified from serum samples by using 1H nuclear magnetic resonance spectroscopy. Results: All interventions induced a significant (P < 0.001–0.003) effect on the overall metabolic profiles. The effect was observed both in participants who had a metabolic profile that reflected higher cardiometabolic risk at baseline (group B: P = 0.001–0.008) and in participants who had a lower-risk profile (group A: P < 0.001–0.009). Although most of the changes in individual metabolites were not statistically significant after correction for multiplicity, clear trends were observed. SB-induced effects were mainly on serum triglycerides and very-low-density lipoprotein (VLDL) and its subclasses, which decreased in metabolic group B. SBo induced a decreasing trend in serum total, intermediate-density lipoprotein (IDL), and low-density lipoprotein (LDL) cholesterol and subfractions of IDL and LDL in group B. During the SBe+MD treatment, VLDL fractions and serum triglycerides increased. Bilberries caused beneficial changes in serum lipids and lipoproteins in group B, whereas the opposite was true in group A. Conclusion: Berry intake has overall metabolic effects, which depend on the cardiometabolic risk profile at baseline. This trial was registered at clinicaltrials.gov as NCT01860547. PMID:23945716

    This study is all about predicting the value of serum vaspin level in the amelioration of fatty liver and metabolic disturbance in patients with severe obesity after laparoscopic vertical banded gastroplasty (LVBG). A total of 164 patients (from January 2012 to May 2015) with severe obesity were chosen and performed LVBG. Enzyme-linked immunosorbent assay was performed to detect the serum vaspin level. The patients were given a biochemical automatic analyzer to measure the biochemical indicators. Homeostasis model assessment (HOMA) helps in the calculation of fasting insulin level (FINS) and insulin resistance (IR). The changes in fatty liver were examined by computed tomography (CT). Receiver operating characteristic curve is used to increase the predictive value of serum vaspin level in the amelioration of liver function and disturbances in the metabolism. Weight, BMI, waist circumference, serum vaspin level, and triglyceride (TG) decreased, but CT value of liver increased at 4th, 7th, and 12th month after surgery. After the 7th and 12th month period of surgery, the alanine aminotransferase, aspartate aminotransferase, FINS, and HOMA-IR reduced in the patients (P liver and metabolic disturbance. This study proves that the serum vaspin level serves as a predictive indicator in the amelioration of fatty liver and metabolic disturbance in patients with severe obesity after LVBG.

    SLC22A12 gene, encoding urate transport 1, has been known to be responsible to urate metabolism. This study sought to determine the association between the novel G109T polymorphism in SLC22A12 with serum uric acid and the development of metabolic syndrome in Korean male subjects. A total of 132 healthy male subjects were enrolled in this study. Metabolic syndrome was determined using the modified guidelines for metabolic syndrome proposed by the National Cholesterol Education Program's Third Adult Treatment Panel. Genotyping for the SLC22A12 gene was assessed using denaturing high-performance liquid chromatography analysis. Serum uric acid and fractional excretion of uric acid (FEUA) from blood and urine samples were measured. Frequencies of the 109GG, 109GT, and 109TT genotypes were 57.6, 38.6, and 3.8%, respectively. Serum uric acid levels and FEUAs were significantly different among the three genotypes of the G109T polymorphism (P = 0.035 and P = 0.033, respectively). In addition, subjects of genotypes with the T allele had lower uric acid levels and higher FEUAs compared to those with the 109GG genotype (P = 0.007 and P = 0.031, respectively). The G109T polymorphism of the SLC22A12 gene has no association with metabolic syndrome. However, a number of metabolic syndrome components were related to serum uric acid level (r = 0.285, P = 0.001) and also significantly different between genotype with and without T allele (P = 0.008). The novel G109T polymorphism of the SLC22A12 gene is related to serum uric acid level, but not to the development of metabolic syndrome.

    Objective To identify potential genes that may be involved in lipid metabolism in rats after treatment with aqueous extract of Arctium lappa L (burdock). Methods Rats were randomly divided into six groups: (i) control (standard diet); (ii) model group (high-fat diet only); (iii) high-fat diet and low-dose aqueous burdock root extract (2 g/kg); (iv) high-fat diet and moderate-dose aqueous burdock root extract (4 g/kg); (v) high-fat diet and high-dose aqueous burdock root extract (8 g/kg); and (vi) a positive control group exposed to a high-fat diet and simvastatin (10 mg/kg). Kyoto Encyclopedia of Genes and Genomes (KEGG) analysis was performed to find the potential candidate genes involved in the modulation of blood lipids by treatment with aqueous burdock root extract. Results Burdock root extract reduced body weight and cholesterol levels in rats. KEGG analysis revealed 113 genes that were involved in metabolic pathways. Of these, 27 potential genes associated with blood lipid metabolism were identified. Conclusions Aqueous extract of burdock root reduced body weight and cholesterol in rats, possibly by modulating the differential expression of genes.

    Full Text Available ABSTRACT This study was conducted to determine the effect of diets containing different levels of thyme essential oil (TEO on performance, some serum parameters and the antioxidative metabolism of the serum and liver tissues in quails. A total number of 200 sixteen-days-old Japanese quails (Coturnix coturnix japonica were used in the study. The animals were divided into 4 groups; the control group was fed only basal diet but groups TEO1, TEO2 and TEO3 had thyme essential oil of 150, 300 and 450 mg/kg, respectively, added to their diets. Body weight and daily weight gain increased with higher levels of thyme essential oil in the feed, yet a statistically significant increase was detected in only group TEO3 (p<0.05. Furthermore, in all of the groups that were fed on TEO, feed intake was significantly higher than that of the control group (p<0.05. In the groups that received thyme essential oil, serum creatinine and low-density lipoprotein (LDL levels were low, whereas serum magnesium levels were high (p<0.05. Thyme essential oil significantly increased in liver catalase (CAT, superoxide dismutase (SOD and glutathione peroxidase (GSH-Px activities and serum CAT and GSH-Px activities, and significantly reduced both liver and serum lipid peroxidation (malondialdehyde=MDA levels (p<0.01. In result, while thyme essential oil partially affected the performance and serum parameters, it had a marked effect on the antioxidant metabolism.

    To determine the relationship between serum uric acid, metabolic syndrome (MetS), and albuminuria in type 2 diabetic patients. A total of 504 Korean patients with type 2 diabetes aged 57.3 years were retrospectively evaluated for clinical histories, anthropometric measurements, and biochemical studies. Urinary albumin excretion (UAE) was measured by a 24-h urine collection. Prevalence of MetS increased according to the quartiles of uric acid levels (≤3.7, 3.8 to 4.5, 4.6 to 5.5, and >5.5 mg/dl; 52.1%, 52.1%, 57.5%, and 71.6%, respectively, Puric acid levels. Serum uric acid levels had significantly increased risk of albuminuria [odds ratio (OR) 1.425, 95% confidence interval (CI) 1.085-1.873] after adjusting for age, gender, and conventional risk factors. Uric acid level remains a significant predictor for abnormal albuminuria after adjusting for MetS presence as well as the use of angiotensin-converting enzyme inhibitor (ACEI) or angiotensin II receptor blocker (ARB) (OR 1.414, 95% CI 1.071-1.868). An elevated uric acid level was significantly associated with MetS and was an independent predictor of albuminuria after adjusting for conventional risk factors and MetS. Regular measurements of uric acid level could give information for predicting the presence of MetS and albuminuria in Korean type 2 diabetic patients. Copyright © 2011 Elsevier Inc.

    We aimed to investigate whether elevated serum uric acid concentrations are associated with higher risk of metabolic syndrome (MetS) and carotid atherosclerosis in patients with type 2 diabetes. We conducted a population-based cross-sectional survey in Shanghai, with a total of 395 men and 631 women age 41 to 92 years. The carotid artery intima-media thickness (IMT) and carotid atherosclerotic plaques (PLQ) were measured by B-mode ultrasound. MetS was defined according to the updated National Cholesterol Education Program Adult Treatment Panel III criteria for Asian Americans. Uric acid levels were negatively associated with duration of diabetes, fasting plasma glucose, glycohemoglobin, eGFR, HDL-cholesterol (all P uric acid levels, the risks were substantially higher for MetS [odds ratio 3.97, (95% confidence interval 2.58-6.13)] (P uric acid levels after multiple adjustment. These associations remained significant after further adjustment for potential confounders. Serum uric acid level is associated with MetS and is an independent risk factor for carotid atherosclerosis in patients with type 2 diabetes.

    Highlights: •Twenty ulcerative colitis patients and nineteen healthy controls were enrolled. •Increased 3-hydroxybutyrate, glucose, phenylalanine, and decreased lipid were found. •We report early stage diagnosis of ulcerative colitis using NMR-based metabolomics. -- Abstract: Ulcerative colitis (UC) has seriously impaired the health of citizens. Accurate diagnosis of UC at an early stage is crucial to improve the efficiency of treatment and prognosis. In this study, proton nuclear magnetic resonance ({sup 1}H NMR)-based metabolomic analysis was performed on serum samples collected from active UC patients (n = 20) and healthy controls (n = 19), respectively. The obtained spectral profiles were subjected to multivariate data analysis. Our results showed that consistent metabolic alterations were present between the two groups. Compared to healthy controls, UC patients displayed increased 3-hydroxybutyrate, β-glucose, α-glucose, and phenylalanine, but decreased lipid in serum. These findings highlight the possibilities of NMR-based metabolomics as a non-invasive diagnostic tool for UC.

    Lipolysis is stimulated by activation of adrenergic inputs to adipose tissues. Our recent study showed that serum concentrations of fatty acid binding protein 4 (FABP4) are robustly elevated in patients with acute myocardial infarction and ventricular tachyarrhythmia, that display a marked activation of the sympathetic nervous system (SNS). However, it remains unknown whether circulating FABP4 concentrations are associated with exercise-induced SNS activation. Thirty one healthy volunteers underwent cardiopulmonary exercise testing on a cycle ergometer up to the workload levels below and above anaerobic threshold, low- and high-intensity exercise, respectively. Serial blood samplings were performed before and after exercise. High-intensity exercise significantly increased serum concentrations of FABP4 and catecholamines, and their concentrations declined fast thereafter in a similar fashion. These changes were accompanied by little, if any, changes in other metabolic markers. Regardless of adiposity, percent change from baseline to peak FABP4 levels (%FABP4) was comparable in all subjects. Stepwise regression analysis revealed that %FABP4 was highly correlated with that in norepinephrine. Our study reveals the significant correlation between circulating FABP4 and norepinephrine levels during exercise testing. Together with the fact that FABP4 is secreted from adipocytes via β-adrenergic-mediated lipolytic mechanisms, this study suggests FABP4 as a potential biomarker for adrenergic overdrive.

    Full Text Available Adipocyte fatty acid binding protein (A-FABP is a key mediator of obesity-related metabolic syndrome (MetS. The aim of this study was to evaluate the relationship between A-FABP concentration and MetS in type 2 diabetes mellitus (DM patients. Fasting blood samples were obtained from 165 type 2 DM volunteers. MetS and its components were defined using diagnostic criteria from the International Diabetes Federation. Among 165 DM patients, 113 patients (68.5% had MetS. Diabetic persons who had MetS had significantly higher A-FABP levels (P<0.001 than those without MetS. Female DM persons had higher A-FABP level than man (P<0.001. No statistically significant differences in A-FABP levels were found in use of statin, fibrate, or antidiabetic drugs. Multivariate forward stepwise linear regression analysis revealed that body fat mass (P<0.001, logarithmically transformed creatinine (log-creatinine; P<0.001, female DM patients (P<0.001, and logarithmically transformed high sensitive C-reactive protein (log-hs-CRP; P=0.013 were positively correlated, while albumin (P=0.004 and glomerular filtration rate (GFR; P=0.043 were negatively correlated with serum A-FABP levels in type 2 DM patients. In this study, higher serum A-FABP level was positively associated with MetS in type 2 DM patients.

    2013-01-01

    Background Adipose tissue is an active endocrine organ which secretes a wide range of hormones and protein factors, collectively termed adipokines. Adipokines affect appetite and satiety, glucose and lipid metabolism, inflammation and immune functions. The objectives were to evaluate serum concentrations of adipokines (adiponectin, leptin, tumor necrosis factor (TNF)-alpha, interleukin (IL)-1beta and IL-6) in lactating dairy cows with postpartum uterine inflammatory conditions (metritis, clinical endometritis or subclinical endometritis) and in cows experiencing loss of body condition, and to assess the relationship of adipokines and body condition loss in the establishment of persistent uterine inflammatory conditions. Methods Lactating multiparous Holstein cows (N = 40), with body condition scores (BCS) from 2 to 4 (eight cows for each 0.5 score increment) were enrolled. Body condition was monitored for all cows weekly for 7 weeks post calving; cows with uterine inflammatory conditions were also re-evaluated 2 weeks later. Blood samples were collected from 1 week prior to calving to 7 weeks after calving for determination of serum concentrations of adipokines, insulin and insulin like growth factor (IGF)-1. Results Cows with metritis or clinical endometritis had higher serum concentrations of adiponectin, leptin, TNF-alpha, IL-1beta and IL-6 compared to normal cows (P cows with subclinical endometritis compared to normal cows (P cows with metritis or clinical endometritis. Cows with low BCS (2 and 2.5) had significantly higher adiponectin, TNF-alpha, IL-1beta and IL-6 than those with high BCS (3 to 4). Cows with persistent uterine inflammatory conditions had higher adiponectin, leptin TNF-alpha, IL-1beta and IL-6 and insulin compared to normal and spontaneously recovered cows, except for IGF-1 (P cows.

    Full Text Available Human serum paraoxonase contributes to the anti-atherogenic effect of high-density lipoprotein cholesterol (HDL-C and has been shown to protect both low-density lipoprotein cholesterol (LDL-C and HDL-C against lipid peroxidation. We investigated the effects of rosiglitazone on paraoxonase activity and metabolic parameters in patients with type 2 diabetes mellitus [50 patients (30 males, 20 females; mean±SD age: 58.7±9.2 years, body mass index: 28.2±4.1'kg/m2], in whom glucose control could not be achieved despite treatment with metformin, sulphonylurea, and/or insulin. The patients were given 4'mg/day rosiglitazone for 3 months in addition to their usual treatment. Serum paraoxonase activity, malondialdehyde, homocysteine, and lipid profile were measured at the time of initiation and at the end of therapy with rosiglitazone. After rosiglitazone therapy, serum levels of HDL-C, apolipoprotein A-1, and paraoxonase activity increased significantly (P<0.05 and malondialdehyde, homocysteine, lipoprotein(a, and glucose levels decreased significantly (P<0.05, but no significant changes in levels of total cholesterol and apolipoprotein B were observed. Triglyceride levels also increased significantly (P<0.05. Rosiglitazone treatment led to an improvement in glycemic control and to an increase in paraoxonase activity and HDL-C levels. Although rosiglitazone showed favorable effects on oxidant/antioxidant balance and lipid profile, further studies are needed to determine the effect of rosiglitazone on cardiovascular risk factors and cardiovascular morbidity and mortality.

    Postweaning growth, sexual development, libido, and carcass data were collected from two consecutive calf crops using 31 Brahman x Angus (B x A), 41 Senepol x Angus (S x A), and 38 Tuli x Angus (T x A) F1 bulls. Following weaning (by mid-September) and preconditioning, at the start of the study (late September) bulls were fed concentrate (three times each week at a rate equivalent to 4.5 kg/d) on bahiagrass pasture for approximately 250 d. At the start of the study and at 28-d intervals, BW, hip height, and scrotal circumference (SC) were measured. Concurrently at 28-d intervals, when the SC of a bull was > or = 23 cm, semen collection was attempted using electroejaculation. Ejaculates were evaluated for presence of first spermatozoa (FS), 50 x 10(6) sperm with at least 10% motility (PU), and 500 x 10(6) sperm with at least 50% motility (PP). After all bulls reached PP they were subjected to two libido tests. Carcass data were collected on all bulls (n = 110) and Warner-Bratzler shear (WBS) force values were assessed on a subset (n = 80). For both years, B x A bulls were heavier (P 0.10) gain in BW or hip height during the study. Scrotal circumference of T x A bulls was larger (P 0.10) of breed type by the end of the study. At PU and PP, B x A bulls were older (P 0.10) USDA quality grade. In conclusion, tropically adapted F1 bulls produced from Senepol (Bos taurus) and Tuli (Sanga) sires bred to Angus cows in Florida had lighter BW, shorter hip heights, and smaller carcasses than those from Brahman sires but reached puberty earlier and had higher libido scores and lower WBS force values.

    Full Text Available Two experiments were conducted assessing the effects of presence or absence of rumen protozoa and dietary nitrate addition on rumen fermentation characteristics and in vitro methane production in Brahman heifers. The first experiment assessed changes in rumen fermentation pattern and in vitro methane production post-refaunation and the second experiment investigated whether addition of nitrate to the incubation would give rise to methane mitigation additional to that contributed by defaunation. Ten Brahman heifers were progressively adapted to a diet containing 4.5% coconut oil distillate for 18 d and then all heifers were defaunated using sodium 1-(2-sulfonatooxyethoxy dodecane (Empicol. After 15 d, the heifers were given a second dose of Empicol. Fifteen days after the second dosing, all heifers were allocated to defaunated or refaunated groups by stratified randomisation, and the experiment commenced (d 0. On d 0, an oral dose of rumen fluid collected from unrelated faunated cattle was used to inoculate 5 heifers and form a refaunated group so that the effects of re-establishment of protozoa on fermentation characteristics could be investigated. Samples of rumen fluid collected from each animal using oesophageal intubation before feeding on d 0, 7, 14, and 21 were incubated for in vitro methane production. On d 35, 2% nitrate (as NaNO3 was included in in vitro incubations to test for additivity of nitrate and absence of protozoa effects on fermentation and methane production. It was concluded that increasing protozoal numbers were associated with increased methane production in refaunated heifers 7, 14, and 21 d after refaunation. Methane production rate was significantly higher from refaunated heifers than from defaunated heifers 35 d after refaunation. Concentration and proportions of major volatile fatty acids, however, were not affected by protozoal treatments. There is scope for further reducing methane output through combining

    Kisspeptin is a peptide encoded by the Kiss 1 gene and is also called metastin. Previous studies have generally focused on several functions of this peptide, including metastasis, puberty, vasoconstriction and reproduction. However, few studies have focused on the cardiac functions of kisspeptin. In the present study, cardiac histomorphology was observed via TEM (transmission electron microscope) and HE and Masson staining to observe instinctive changes. Serum metabolites levels were also measured and analyzed using GC/TOF-MS after injection with kisspeptin-10. A gene chip was employed to screen the potential genes and pathways in the myocardium at the transcriptional leve, while RT-PCR and Western Blot were conducted to verify the relevant mRNA and protein expression, respectively. Histopathological findings demonstrated that there were many irregular wavy contractions through HE staining and increased fibrosis around the heart cells through Masson staining after treatment with kisspeptin-10. Additionally, the main changes in ultrastructure, including changes in mitochondrial and broken mitochondrial cristae, could be observed with TEM after treatment with kisspeptin-10. The PCA scores plot of the serum metabolites was in the apparent partition after injection of kisspeptin-10. Twenty-six obviously changed metabolites were detected and classified as amino acids, carbohydrate metabolites, organic acids and other metabolites. Furthermore, gene chip analysis showed 1112 differentially expressed genes after treatment with kisspeptin-10, including 330 up-regulated genes and 782 down-regulated genes. These genes were enriched in several signaling pathways related to heart diseases. The RT-PCR result for ITGB8, ITGA4, ITGB7, MYL7, HIF1-α and BNP corresponded with the gene chip assay. Moreover, the upregulated genes ITGB8, ITGA4 and BNP also displayed consistent protein levels in Western Blot results. In summary, these findings suggest that kisspeptin-10 could alter the

    Early diagnosis of diabetic nephropathy (DN) is difficult although it is of crucial importance to prevent its development. To probe potential markers and the underlying mechanism of DN, an animal model of DN, the db/db mice, was used and serum and urine metabolites were profiled using gas chromatography/time-of-flight mass spectrometry. Metabolic patterns were evaluated based on serum and urine data. Principal component analysis of the data revealed an obvious metabonomic difference between db/db mice and controls, and db/db mice showed distinctly different metabolic patterns during the progression from diabetes to early, medium, and later DN. The identified metabolites discriminating between db/db mice and controls suggested that db/db mice have perturbations in the tricarboxylic acid cycle (TCA, citrate, malate, succinate, and aconitate), lipid metabolism, glycolysis, and amino acid turnover. The db/db mice were characterized by acidic urine, high TCA intermediates in serum at week 6 and a sharp decline thereafter, and gradual elevation of free fatty acids in the serum. The sharp drop of serum TCA intermediates from week 6 to 8 indicated the downregulated glycolysis and insulin resistance. However, urinary TCA intermediates did not decrease in parallel with those in the serum from week 6 to 10, and an increased portion of TCA intermediates in the serum was excreted into the urine at 8, 10, and 12 wk than at 6 wk, indicating kidney dysfunction occurred. The relative abundances of TCA intermediates in urine relative to those in serum were suggested as an index of renal damage.

    The toxicity of Nanjing drinking water on mouse (Mus musculus) was detected by (1)H nuclear magnetic resonance (NMR)-based metabonomic method. Three groups of mice were fed with drinking water (produced by Nanjing BHK Water Plant), 3.8 μg/L benzo(a)pyrene as contrast, and clean water as control, respectively, for 90 days. It was observed that the levels of lactate, alanine, and creatinine in the mice fed with drinking water were increased and that of valine was decreased. The mice of drinking water group were successfully separated from control. The total concentrations of polycyclic aromatic hydrocarbons (PAHs), phthalates (PAEs), and other organic pollutants in the drinking water were 0.23 μg/L, 4.57 μg/L, and 0.34 μg/L, respectively. In this study, Nanjing drinking water was found to induce distinct perturbations of metabolic profiles on mouse including disorders of glucose-alanine cycle, branched-chain amino acid and energy metabolism, and dysfunction of kidney. This study suggests that metabonomic method is feasible and sensitive to evaluate potential toxic effects of drinking water.

  1. Serum proteomic analysis identifies sex-specific differences in lipid metabolism and inflammation profiles in adults diagnosed with Asperger syndrome

    2014-01-01

    Background The higher prevalence of Asperger Syndrome (AS) and other autism spectrum conditions in males has been known for many years. However, recent multiplex immunoassay profiling studies have shown that males and females with AS have distinct proteomic changes in serum. Methods Here, we analysed sera from adults diagnosed with AS (males = 14, females = 16) and controls (males = 13, females = 16) not on medication at the time of sample collection, using a combination of multiplex immunoassay and shotgun label-free liquid chromatography mass spectrometry (LC-MSE). The main objective was to identify sex-specific serum protein changes associated with AS. Results Multiplex immunoassay profiling led to identification of 16 proteins that were significantly altered in AS individuals in a sex-specific manner. Three of these proteins were altered in females (ADIPO, IgA, APOA1), seven were changed in males (BMP6, CTGF, ICAM1, IL-12p70, IL-16, TF, TNF-alpha) and six were changed in both sexes but in opposite directions (CHGA, EPO, IL-3, TENA, PAP, SHBG). Shotgun LC-MSE profiling led to identification of 13 serum proteins which had significant sex-specific changes in the AS group and, of these, 12 were altered in females (APOC2, APOE, ARMC3, CLC4K, FETUB, GLCE, MRRP1, PTPA, RN149, TLE1, TRIPB, ZC3HE) and one protein was altered in males (RGPD4). The free androgen index in females with AS showed an increased ratio of 1.63 compared to controls. Conclusion Taken together, the serum multiplex immunoassay and shotgun LC-MSE profiling results indicate that adult females with AS had alterations in proteins involved mostly in lipid transport and metabolism pathways, while adult males with AS showed changes predominantly in inflammation signalling. These results provide further evidence that the search for biomarkers or novel drug targets in AS may require stratification into male and female subgroups, and could lead to the development of novel targeted treatment

The main objective was to identify sex-specific serum protein changes associated with AS. Multiplex immunoassay profiling led to identification of 16 proteins that were significantly altered in AS individuals in a sex-specific manner. Three of these proteins were altered in females (ADIPO, IgA, APOA1), seven were changed in males (BMP6, CTGF, ICAM1, IL-12p70, IL-16, TF, TNF-alpha) and six were changed in both sexes but in opposite directions (CHGA, EPO, IL-3, TENA, PAP, SHBG). Shotgun LC-MSE profiling led to identification of 13 serum proteins which had significant sex-specific changes in the AS group and, of these, 12 were altered in females (APOC2, APOE, ARMC3, CLC4K, FETUB, GLCE, MRRP1, PTPA, RN149, TLE1, TRIPB, ZC3HE) and one protein was altered in males (RGPD4). The free androgen index in females with AS showed an increased ratio of 1.63 compared to controls. Taken together, the serum multiplex immunoassay and shotgun LC-MSE profiling results indicate that adult females with AS had alterations in proteins involved mostly in lipid transport and metabolism pathways, while adult males with AS showed changes predominantly in inflammation signalling. These results provide further evidence that the search for biomarkers or novel drug targets in AS may require stratification into male and female subgroups, and could lead to the development of novel targeted treatment approaches.

    Full Text Available PurposePrevious studies have revealed many inconsistent results regarding the relationship between vitamin D and metabolic syndrome. The purpose of our study was to investigate the association between serum 25-hydroxyvitamin D (25(OHD concentration and factors that characterize metabolic syndrome in Korean children and adolescents.MethodsWe analyzed data from 2,880 children and adolescents aged 10-18 years collected from the 2008-2010 Korean National Health and Nutrition Examination Survey. We investigated the data according to quartiles of 25(OHD concentrations.ResultsSystolic blood pressure and diastolic blood pressure with adjustment for sex and age differed significantly between the serum 25(OHD groups and exhibited negative trend as 25(OHD concentrations increased. The number of subjects with metabolic syndrome was greater in the low 25(OHD groups (I, II, and III quartile than in the high 25(OHD group (IV quartile (P=0.029. BMI and waist circumference were lower in the high 25(OHD group. Serum 25(OHD concentration correlated negatively with homeostasis model assessment estimate of insulin resistance (ρ=-0.073, P<0.001 and correlated positively with quantitative insulin sensitivity check index (ρ=0.095, P<0.001.ConclusionLow serum 25(OHD level is associated with an increase of insulin resistance and metabolic syndrome in children and adolescents.

    Full Text Available Type-2 diabetes mellitus and periodontal disease are complex human diseases. Pathogenesis of both ailments is multifactorial, involving chronic disease courses with varied clinical presentations. It is well established in the scientific literature that both diseases are interrelated; in particular, individuals suffering from diabetes are at a higher risk of developing periodontitis. The present review analyzed, using a hypothetical model, the complex factors that may influence the two diseases indirectly, including lifestyle, obesity, diabetes control, oral health behavior, and serum inflammatory factors, and even quality of life. In this review, special attention was given to exploring plausible theoretical or practical explanations of the interrelations and the contemporary evidence base underpinning these. Since the impact of individual general or oral health quality of life factors are substantial, it is very important for health care professionals to appreciate the influence of these factors as controlling these help assist in management of both type-2 diabetes and periodontal diseases thus reducing the social burden of these two complex disease in various populations.

    Tumour burden is one of the most important prognosticators for pancreatic ductal adenocarcinoma (PDAC). The aim of this study was to investigate the predictive significance of metabolic tumour burden measured by {sup 18}F-FDG PET/CT in patients with resectable PDAC. Included in the study were 122 PDAC patients who received preoperative {sup 18}F-FDG PET/CT examination and radical pancreatectomy. Metabolic tumour burden in terms of metabolic tumour volume (MTV) and total lesion glycolysis (TLG), pathological tumour burden (tumour size), serum tumour burden (baseline serum CA19-9 level), and metabolic activity (maximum standard uptake value, SUVmax) were determined, and compared for their performance in predicting overall survival (OS) and recurrence-free survival (RFS). MTV and TLG were significantly associated with baseline serum CA19-9 level (P = 0.001 for MTV, P < 0.001 for TLG) and tumour size (P < 0.001 for MTV, P = 0.001 for TLG). Multivariate analysis showed that MTV, TLG and baseline serum CA19-9 level as either categorical or continuous variables, but not tumour size or SUVmax, were independent risk predictors for both OS and RFS. Time-dependent receiving operating characteristics analysis further indicated that better predictive performances for OS and RFS were achieved by MTV and TLG compared to baseline serum CA19-9 level, SUVmax and tumour size (P < 0.001 for all). MTV and TLG showed strong consistency with baseline serum CA19-9 level in better predicting OS and RFS, and might serve as surrogate markers for prediction of outcome in patients with resectable PDAC.

    Fixed-time AI (FTAI) is a powerful tool for genetic improvement of extensively managed beef cattle. A genomewide association study (GWAS) was conducted to investigate genes and genetic markers associated with the outcome (pregnant or not pregnant) of FTAI in 614 commercial Brahman heifers genotyped for 18,895 SNP and imputed to 51,588 SNP. The likelihood of Brahman heifers becoming pregnant after hormonal treatment to synchronize ovulation followed by FTAI was influenced by the content of their genomes, as determined by a principal component analysis. The principal component analysis involved comparisons between the studied heifers and populations of known and ancestry. The heritability of FTAI outcome was = 0.18, which is higher than for most other reproductive outcome traits. The number of SNP associated with FTAI outcome was 101 ( genomic regions emerge as important for overall Brahman heifer fertility, which mapped to chromosomes 1, 7, and 9. Further analyses, including improved genome annotation, are required to elucidate the link between these regions and heifer fertility. Additional studies are needed to confirm SNP and gene associations reported herein and further elucidate the genetics of FTAI outcome. Future GWAS should target other Braham populations and additional cattle breeds with FTAI records, including breeds with higher ancestry.

    Full Text Available The objective of this research was to determine the effect of synchronizing the rate of degradation of dietary energy and nitrogen release on growth performance in Brahman beef cattle. Fifteen Brahman cattle, 1.5 years old, with an average initial body weight of 184.8±11.1 kg were assigned to one of three treatments according to a randomized complete block design. Dietary treatments contained 3 levels of synchrony index (0.39, 0.56 and 0.74 that were derived from laboratory chemical composition analysis and degradation kinetics using nylon bag technique. Diets were fed at the rate of 2.5% BW by separate concentrate and roughage. Average daily gain increased linearly (P<0.05 with increase levels of synchrony index in the diets. The digestibility of dry matter, organic matter and neutral detergent fiber increased linearly (P<0.01. The digestibility of acid detergent fiber increased linearly (P<0.05. Ruminal total volatile fatty acids concentration increased linearly (P<0.05 at 6 h post feeding. Higher concentration and fluctuation of ruminal ammonia nitrogen and blood urea nitrogen were observed in animals that received lower synchrony index in their diets. Rumen microbial population tended to increase with diets having higher levels of synchrony index. The results indicated that synchronized rate of dietary energy and nitrogen degradation improved ruminal fermentation and digestibility, thus this increased the growth rate in Brahman cattle fed with ricestraw- based diets.

    To investigate the prevalence of hyperuricemia and the association between the serum uric aci (SUA) levels and incidence of metabolic syndrome (MetS) in the Mongolian area of China. This cross-sectional survey was based on a population of 1,426 subjects (809 men and 617 women) 20-80 years of age who were recruited from Inner Mongolia, China. Metabolic and anthropometric indicators were measured according to standard methods. Hyperuricemia was defined as an SUA level of ≥7.0 mg/dL for men and ≥6.0 mg/dL for women. MetS was diagnosed based on the consensus criteria released in 2009 from a joint collaboration organization. The prevalence of hyperuricemia was 17.7% in men and 5.2% in women. The prevalence of MetS in men was higher than that observed in women(36.7% vs. 17.8%). Waist circumference, BMI and the level of triglycerides were most strongly correlated with the SUA level in both sexes. Men with hyperuricemia had an increased risk of MetS [OR(95%CI)=2.95(2.00-4.35)], while men with a "normal" SUA level(>5.0 mg/dL and <6.3 mg/dL) had a higher risk of MetS, central obesity and hypertriglyceridemia than men in the lower level group (≤5 mg/dL). Women with a higher SUA level(≥4.3 mg/dL) had an increased risk of MetS, central obesity, hypertriglyceridemia and hypertension compared with women in the lowest tertile SUA group (≤3.5 mg/dL). The SUA level is significantly associated with various metabolic indicators. In this study, waist circumference and the level of triglycerides were most strongly correlated with the SUA level in both sexes. Individuals with a normal level of SUA had an increased risk of MetS and other metabolic disorders. Further research on appropriate cut-off values for pre-hyperuricemia is expected, and the early detection of hyperuricemia is essential for the prevention of MetS.

    The purpose of the study was to identify serum microRNAs providing a link between male subfertility and metabolic syndrome (MetS) and validate their diagnostic potential. Sera were analyzed for fertility and MetS-related parameters in subfertile men (n = 79) and controls (n = 38). Literature review identified miR-155-5p, miR-122-5p, miR-200a-3p, and miR-200c-3p which previously were associated with parameters of fertility as well as metabolic disorders. They were measured in the sera using an absolute quantitation method (qPCR). In order to investigate the value of miRNAs in predicting subfertility, receiver operating characteristic analysis was done. Subfertile men had higher concentrations of miR-155-5p than controls (p = 0.003) and for miR-200c-3p, the difference was borderline statistically significant (p = 0.05). miR-155-5p and miR-200c-3p were also associated with subfertility in men with no metabolic disturbances (p = 0.008, p = 0.004, respectively). This association was abrogated if any component of MetS was present. The combination of miR-155-5p and miR-200c-3p with follicle-stimulating hormone, being a well-established subfertility parameter, resulted in an overall diagnostic power of AUC = 0.87, which was even higher when men without MetS components were analyzed (AUC = 0.93). Regarding MetS components, statistically significant correlations were found between miR-122-5p and fasting triglycerides, and waist circumference, but no association with subfertility was identified. Among the four miRNAs analyzed, none of them was associated both with male subfertility and MetS components. The ability of miR-155-5p and miR-200c-3p to identify subfertile men was partly overruled by the presence of metabolic disturbances.

    2015-01-01

    Full Text Available Background: This systematic review paper aims to study the experimental and human studies on the relationship between metabolic syndrome (MetS, its component and selenium (Se concentration. Materials and Methods: The literature was searched in PubMed, Scopus, and Google Scholar databases with no time limitation using MetS X and Se key words in medical subject heading. The related papers were selected in three phases. After quality assessment, two reviewers extracted the data, whereas the third reviewer checked their extracted data. All evidence comes from experimental and laboratory studies. Results: Finally, 18 articles were included. While, some studies documented that as an antioxidant agent, Se might be correlated with endothelial function, large controversy exists about the type of correlation including positive, negative, and no correlation between MetS and Se levels in body. Some of the reviewed studies were focused on antioxidant supplementation effects on MetS, results also varied in this regard. Conclusion: This inconsistency could be because of diversity in study design, population, lack of special focus on Se and MetS, and finally the complex nature of MetS.

    This study aimed to evaluate the cholesterol-lowering effect of epiberberine in dyslipidemia Syrian golden hamsters induced by high fat and high cholesterol (HFHC) diet and its regulation mechanism on some key genes involved in cholesterol metabolism. Hamsters were divided into six groups: normal control group (NC), HFHC group, simvastatin (Sim) and three doses of epiberberine group. The body weight, organs weight and serum lipid levels, as well as total cholesterol (TC) and total bile acids (TBA) levels in liver and feces were determined. Furthermore, the antidyslipidemia effect of epiberberine on key genes involved in cholesterol biosynthesis, uptake, conversion and elimination such as 3-hydroxy-3-methylglutaryl-CoA reductase (HMGCR), low density lipoprotein receptor (LDL receptor), 7-alpha-hydroxylase (CYP7A1) and apical sodium dependent bile acid transporter (ASBT) were investigated. The results showed that epiberberine at high dosage significantly reduced serum TC, low density lipoprotein cholesterol (LDL-c) and TBA levels by 20.2%, 22.3% and 43.8%, respectively, and increased TBA and TC levels in feces. Epiberberine inhibited HMGCR mRNA and protein expressions and slightly reduced the protein level of ASBT, as well as dramatically up-regulated mRNA and protein expressions of CYP7A1 and LDL receptor. These findings suggested that the antidyslipidemia effects of epiberberine can be achieved via inhibiting the synthesis of cholesterol, promoting the uptake and conversion of TC in liver and increasing the excretion of TC and TBA in feces. Thus, epiberberine should be considered as one of the promising natural drugs for the treatment of dyslipidemia. Copyright © 2015 Elsevier B.V. All rights reserved.

    Full Text Available Hypobaric hypoxia (HH during airline travel induces several (patho- physiological reactions in the human body. Whereas severe hypoxia is investigated thoroughly, very little is known about effects of moderate or short-term hypoxia, e.g. during airline flights. The aim of the present study was to analyse changes in serum protein expression and activation of signalling cascades in human volunteers staying for 30 min in a simulated altitude equivalent to airline travel. After approval of the local ethics committee, 10 participants were exposed to moderate hypoxia (simulation of 2400 m or 8000 ft for 30 min in a hypobaric pressure chamber. Before and after hypobaric hypoxia, serum was drawn, centrifuged, and analysed by two-dimensional gel electrophoresis (2-DIGE and matrix-assisted laser desorption/ionization followed by time-of-flight mass spectrometry (MALDI-TOF. Biological functions of regulated proteins were identified using functional network analysis (GeneMania®, STRING®, and Perseus® software. In participants, oxygen saturation decreased from 98.1 ± 1.3% to 89.2 ± 1.8% during HH. Expression of 14 spots (i.e., 10 proteins: ALB, PGK1, APOE, GAPDH, C1QA, C1QB, CAT, CA1, F2, and CLU was significantly altered. Bioinformatic analysis revealed an association of the altered proteins with the signalling cascades “regulation of haemostasis” (four proteins, “metabolism” (five proteins, and “leukocyte mediated immune response” (five proteins. Even though hypobaric hypoxia was short and moderate (comparable to an airliner flight, analysis of protein expression in human subjects revealed an association to immune response, protein metabolism, and haemostasis

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

    Insulin and uric acid were shown affect the prevalence of Metabolic Syndrome (MetS), but no studies examine their interaction. Therefore, we conducted this study to determine their biological interaction in subjects from central Mexico. 433 subjects were enrolled for a cross-sectional study. MetS was defined according to the Harmonizing Definition. Hyperuricemia was defined as ≥7.0 mg/dL in males and ≥5.8 mg/dL in females. Hyperinsulinemia was defined as ≥11.0 μU/mL. Pearson correlation coefficient (r) was calculated to determine the association between uric acid or insulin and MetS. Logistic regression was used to determine the risk (odds ratio) of developing MetS. Biological interactions were determined by the PROCESS Macro and Anderson's method. Insulin and uric acid levels were elevated in MetS positive group (p uric acid and insulin was associated with the number of MetS components (PROCESS Model 1, interaction coefficient = -0.009, 95%CI: -0.017 to -0.001, p = .036). Johnson-Neyman analysis suggests the interaction is lost when uric acid concentration increased >7.0 mg/dL. When the cohort was separated by hyperinsulinemia and hyperuricemia, there was a significant risk of developing MetS for subjects with hyperuricemia (odds ratio = 2.3; 95%CI: 1.1-4.8, p uric acid and insulin augments the prevalence of MetS; however, no biological interaction was determined for hyperuricemia and hyperinsulinemia.

    Hyperuricemia has been associated with hypertension, diabetes mellitus, and metabolic syndrome. We studied the association between hyperuricemia and glycemic status in a nonrandomized sample of primary care patients. This was a cross-sectional study of adults ≥20 years old who were members of a community-based health care program. Hyperuricemia was defined as a value >7.0 mg/dL for men and >6.0 mg/dL for women. The sample comprised 720 participants including controls (n=257) and patients who were hypertensive and euglycemic (n=118), prediabetic (n=222), or diabetic (n=123). The mean age was 42.4±12.5 years, 45% were male, and 30% were white. The prevalence of hyperuricemia increased from controls (3.9%) to euglycemic hypertension (7.6%) and prediabetic state (14.0%), with values in prediabetic patients being statistically different from controls. Overall, diabetic patients had an 11.4% prevalence of hyperuricemia, which was also statistically different from controls. Of note, diabetic subjects with glycosuria, who represented 24% of the diabetic participants, had a null prevalence of hyperuricemia, and statistically higher values for fractional excretion of uric acid, Na excretion index, and prevalence of microalbuminuria than those without glycosuria. Participants who were prediabetic or diabetic but without glycosuria had a similarly elevated prevalence of hyperuricemia. In contrast, diabetic patients with glycosuria had a null prevalence of hyperuricemia and excreted more uric acid and Na than diabetic subjects without glycosuria. The findings can be explained by enhanced proximal tubule reabsorption early in the course of dysglycemia that decreases with the ensuing glycosuria at the late stage of the disorder.

    Full Text Available Abstract Background There are few studies to demonstrate the associations between newly addressed lipid profiles and metabolic syndrome (MetS-associated variables. Methods Study participants without medications for hypertension, diabetes, or dyslipidemia {614 men aged 58 ± 14 (mean ± standard deviation; range, 20-89 years and 779 women aged 60 ± 12 (range, 21-88 years} were randomly recruited from a single community at the time of their annual health examination. The association between lipid profiles (total cholesterol (T-C, triglycerides (TG, low-density lipoprotein cholesterol (LDL-C, high-density lipoprotein cholesterol (HDL-C, non-HDL-C, T-C/HDL-C, TG/HDL-C, LDL-C/HDL-C ratio and MetS, Insulin resistance by homeostasis model assessment of insulin resistance (HOMA-IR, and serum HMW adiponectin were analyzed. Results In multiple linear regression analysis, TG/HDL-C and T-C/HDL-C ratios as well as TG showed significantly strong associations with all three MetS-associated variables in both men and women. In men, the ROC curve analyses showed that the best marker for these variables was TG/HDL-C ratio, with the AUC for presence of MetS (AUC, 0.82; 95% CI, 0.77-0.87, HOMA-IR (AUC, 0.75; 95% CI, 0.70-0.80, and serum HMW adiponectin (AUC, 0.67; 95% CI, 0.63-0.71, respectively. The T-C/HDL-C ratio, TG, HDL-C, LDL-C/HDL-C ratio, and non-HDL-C also discriminated these markers; however all their AUC estimates were lower than TG/HDL-C ratio. These results were similar in women. Conclusion In Japanese community-dwelling adults, lipid ratios of TG/HDL-C, T-C/HDL-C, LDL-C/HDL-C as well as TG and HDL-C were consistently associated with MetS, insulin resistance and serum HMW adiponectin. Lipid ratios may be used as reliable markers.

    Few studies have investigated the relationship between carotid-femoral pulse wave velocity (cfPWV) and serum alanine aminotransferase (ALT) normal-range levels across the world. The current analysis was designed to explore the relationship of serum ALT normal-range levels to cfPWV and metabolic syndrome (Mets) in non-drinkers and drinkers in a Chinese community-dwelling population. There were 2202 participants with serum ALT levels within normal range enrolled for the current analysis. Median (range) age of participants was 53 (18-96) years, 51.5% were males, and 31.2% were drinkers. Prevalence of Mets was 29.4%. Median (range) of cfPWV was 10.1 (2.4-32.7) m/s. Hazard ratios for prevalence of Mets, central obesity and high triglyceride significantly increased with elevated levels of serum ALT in both non-drinkers and drinkers (p  10 m/s, high blood pressure and high blood glucose significantly increased with elevated levels of serum ALT in non-drinkers (p Chinese community-dwelling population, prevalence of Mets and its components (including central obesity and high TG) increased with an elevation in serum ALT levels within normal range in both non-drinkers and drinkers, while cfPWV and other components of Mets, such as high blood pressure and glucose, increased with an elevation in serum ALT levels in non-drinkers, but not in drinkers.

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

    The effect of uric acid (UA) on the pathogenesis of metabolic disorders is highly dependent on its physicochemical properties, and hyperuricaemia associated with different conditions may have different clinical meanings. The aim of the present study was to investigate the association of serum UA levels with metabolic syndrome and non-alcoholic fatty liver disease (NAFLD) in a middle-aged and elderly population with normal and impaired renal function. The cross-sectional study was performed on 1141 participants (426 men, 715 women; mean age 62 years) enrolled from the Shanghai Changfeng community. Each participant underwent a standard interview, with anthropometric and laboratory measurements. Hepatic fat content (HFC) was determined by a newly established quantitative ultrasound method. Univariate correlation analysis showed that serum UA was associated with all components of metabolic syndrome and HFC (r = 0.193, P metabolic syndrome and NAFLD in participants with normal renal function, but not in those with eGFR metabolic syndrome and NAFLD in patients with normal renal excretory function. However, in those with renal insufficiency, hyperuricaemia has no association with metabolic disorders. © 2012 The Authors Clinical and Experimental Pharmacology and Physiology © 2012 Wiley Publishing Asia Pty Ltd.

    Full Text Available We investigated the independent and combined effects of alcohol consumption, cigarette smoking and metabolic syndrome on abnormal liver function, i.e., the elevation of serum liver enzyme levels. Participants of a Korean population-based prospective cohort aged ≥30 years without liver disease, diabetes, or cardiovascular diseases were included. Information on alcohol consumption, smoking status, and metabolic syndrome, defined as per the criteria of the Adult Treatment Panel III, were applied to evaluate their impact on serum levels of aspartate aminotransferase (AST, alanine aminotransferase (ALT, and gamma-glutamyl transferase (GGT. Alcohol consumption, cigarette smoking and metabolic syndrome were the significant individual factors that elevated serum liver enzyme levels. Supra-additive effects of metabolic syndrome and either alcohol consumption or cigarette smoking were also identified. The combination of heavy drinking (≥24 g/day and metabolic syndrome conferred an effect that was higher than the sum of the two individual effects (Synergic Index (SI: AST, 2.37 [1.20-4.67]; GGT, 1.91 [1.17-3.13]. Only GGT level (odds ratio 6.04 [3.68-9.94], SI 2.33 [1.24-4.41] was significantly elevated when the effect of moderate drinking (20 pack years, 1.80 for ≥24 g/day and ≤20 pack years, 2.03 for ≥24 g/day and >20 pack years, while only the combined effect of drinking ≥24 g/day and smoking >20 pack years elevated the AST level (SI 4.55 [3.12-6.61]. The combined effect of cigarette smoking and metabolic syndrome was not supra-additive. To prevent fatty liver disease and other related diseases, a multifactorial prevention strategy that includes limited alcohol consumption, smoking cessation and rectification of adverse metabolic profiles is required.

    It has previously been reported that increased level of serum heat shock proteins (Hsps) antibody in patients with metabolic syndrome. It is possible that the expression of Hsp and inflammatory markers can be affected by cupping and traditional Chinese medicine. There is a little data investigating the effects of cupping on markers of inflammation and Hsp proteins, hence, the objective of this study was evaluation of the effects of wet cupping on serum high-sensitivity C-reactive protein (hs-CRP) and Hsp27 antibody titers in patients with metabolic syndrome. Serum Hs-CRP and Hsp27 antibody titers were assessed in samples from 126 patients with metabolic syndrome (18-65 years of age) at baseline, and after 6 and 12 weeks after treatment. One hundred and twenty-six patients were randomly divided into the experimental group treated with wet cupping combined with dietary advice, and the control group treated with dietary advice alone using a random number table. Eight patients in case group and five subjects in control groups were excluded from the study. Data were analyzed using SPSS 15.0 software and a repeated measure ANCOVA. Serum hs-CRP titers did not change significantly between groups (p>0.05) and times (p=0.27). The same result was found for Hsp27 titers (p>0.05). Wet-cupping on the interscapular region has no effect on serum hs-CRP and Hsp27 patients with metabolic syndrome. Copyright © 2014 Elsevier Ltd. All rights reserved.

    Measurement of serum haptoglobin (Hapto) concentrations results in only moderate reported specificity and sensitivity for the detection of metritic cows. The objective of this study was to evaluate associations between different variables and haptoglobin concentrations after calving. Parity, periparturient metabolic stress indicated by β-hydroxybutyric acid (BHBA) and nonesterified fatty acids (NEFA), calving difficulties, retained fetal membranes (RFM), and acute puerperal metritis (APM) were evaluated. A total of 443 Holstein Friesian cows were enrolled in this retrospective observational study. Acute puerperal metritis was diagnosed when a cow had fetid, reddish-brown, watery vaginal discharge in combination with rectal temperature ≥39.5°C. The retention of the fetal membranes has been defined as the failure to expel the fetal membranes within 12h after calving. Results of blood samples from 2 and 5 d in milk (DIM) were analyzed for Hapto, BHBA, and NEFA. Primiparous cows had a greater median Hapto concentration than multiparous cows at 5 DIM [primiparous: 2.25g/L, interquartile range (IQR) 1.45-2.50, n=146; multiparous: 1.13g/L, IQR 0.52-2.22, n=302; Pcows (1.4g/L), primiparous cows (2.49g/L), and multiparous cows (1.4g/L) were used for further analysis. Periparturient metabolic stress indicated by elevated BHBA (≥1.2mmol/L) at 5 DIM was associated with elevated Hapto (odds ratio 2.39-2.87) regardless of parity. In contrast, elevated NEFA (≥0.6mmol/L) at 2 DIM was not a risk factor for elevated Hapto. Multiparous cows with assisted calving had a 2.46 times higher risk for elevated Hapto, whereas primiparous cows with assisted calving had no elevated risk for elevated Hapto at 5 DIM. Moreover, multiparous cows with RFM were 5.51 times more likely to have elevated Hapto at 5 DIM than cows without RFM. Acute puerperal metritis within the first 5 DIM was associated with elevated Hapto (odds ratio 2.74-5.01), regardless of parity. We speculate that the

    Full Text Available Objective. This study aimed to evaluate the association between serum uric acid (SUA levels within a normal to high range and the risk of metabolic syndrome (MetS among community elderly and explore the sex difference. Design and Methods. A cross-sectional study was conducted in a representative urban area of Beijing between 2009 and 2010. A two-stage stratified clustering sampling method was used and 2102 elderly participants were included. Results. The prevalence of hyperuricemia and MetS was 16.7% and 59.1%, respectively. There was a strong association between hyperuricemia and four components of MetS in women and three components in men. Multiple logistic regression analysis showed ORs of hyperuricemia for MetS were 1.67 (95% CI: 1.11–2.50 in men and 2.73 (95% CI: 1.81–4.11 in women. Even in the normal range, the ORs for MetS increased gradually according to SUA levels. MetS component number also showed an increasing trend across SUA quartile in both sexes (P for trend < 0.01. Conclusion. This study suggests that higher SUA levels, even in the normal range, are positively associated with MetS among Chinese community elderly, and the association is stronger in women than men. Physicians should recognize MetS as a frequent comorbidity of hyperuricemia and take early action to prevent subsequent disease burden.

    There has been increasing interest in non-skeletal interactions between vitamin D insufficiency, which is common, and cardiovascular event and cardiovascular disease (CVD) risk factors. To evaluate cross-sectional associations between dietary and serum vitamin D status and metabolic abnormalities and arterial changes among 1054 adults aged ≥40 y (404 men and 650 women) in a rural area of South Korea. Study subjects were divided into three groups according to dietary vitamin D intake (tertiles) measured by food frequency questionnaire and serum 25(OH)D levels (≤20, 21-29, and ≥30 ng/mL). Metabolic components (blood pressure, lipid profiles, and glycemic index) and arterial changes (brachial ankle pulse wave velocity [baPWV] and carotid artery intima-media wall thickness [cIMT]) were measured. Dietary vitamin D was inversely associated with diastolic blood pressure (DBP) and baPWV among men, but the association disappeared after multinutrient supplement users were excluded. Among women, there was an inverse association between dietary vitamin D and triacylglycerol (TG) levels. However, serum 25(OH)D showed a significant positive relationship with HDL cholesterol in both men and women, while a positive linear trend or nonlinear trend with serum 25(OH)D levels was shown in TG levels among men and in systolic blood pressure (SBP), DBP, total cholesterol, and baPWV among women. The positive relationship between serum 25(OH)D with baPWV disappeared after adjustment for blood pressure. Serum 25(OH)D may be favorably related to HDL cholesterol. However, serum 25(OH)D may not favorably related to subclinical atherosclerosis and arterial stiffness measured by cIMT and baPWV. The positive relationship between 25(OH)D and baPWV is likely to be mediated by blood pressure. Copyright © 2016 Elsevier Inc. All rights reserved.

    High-density lipoprotein cholesterol (HDLC) is anti-inflammatory in the basal state and pro-inflammatory during the acute-phase response. Blood mercury also has an inflammatory property. Therefore, the aim of this study was to investigate the relationship between serum HDLC and blood mercury concentration in relation with metabolic syndrome (MS). The data of 7616 subjects (3713 men and 3903 women), over 20 years of age, from 2008 to 2013, Korea National Health and Nutrition Examination Survey were selected for cross-sectional analyses. Correlation and regression of serum HDLC and blood mercury were initially done. We compared serum HDLC concentration according to blood mercury quartile after adjustment for relevant variables in subjects with MS. Mean blood mercury concentrations is 5.6 and 3.9 μg/dL in men and women, respectively. Blood mercury concentration in MS subjects was positively correlated with serum HDLC concentration, especially in men. In addition, HDLC concentration was significantly higher according to the higher blood mercury quartile. Serum HDLC was positively associated with blood mercury concentration in MS Korean men. Therefore, elevated blood mercury may be a factor to increase serum HDLC concentration in MS men.

    Plant sterols (PS) in parenteral nutrition (PN) may contribute to intestinal failure-associated liver disease. We investigated interrelations between serum PS, liver function and histology, cholesterol metabolism, and characteristics of PN. Eleven patients with intestinal failure (mean age 6.3 years) receiving long-term PN were studied prospectively (mean 254 days) and underwent repeated measurements of serum lipids, noncholesterol sterols, including PS, and liver enzymes. PS contents of PN were analyzed. Liver biopsy was obtained in 8 patients. Twenty healthy children (mean age 5.7 years) served as controls. Median percentage of parenteral energy of total daily energy (PN%) was 48%, including 0.9 g · kg(-1) · day(-1) of lipids. Respective amounts of PN sitosterol, campesterol, avenasterol, and stigmasterol were 683, 71, 57, and 45 μg · kg(-1) · day(-1). Median serum concentrations of sitosterol (48 vs 7.5 μmol/L, P liver enzymes remained close to normal range. Glutamyl transferase correlated with serum PS (r = 0.61-0.62, P Liver fibrosis in 5 patients reflected increased serum PS (r = 0.55-0.60, P = 0.16-0.12). Serum PS moderately increase during olive oil-based PN, and correlate positively with PN% and glutamyl transferase. Despite well-preserved liver function, histology often revealed significant liver damage.

    The purpose of this study was to assess the effects of artificial shade, tree shade, and no shade on physiological changes, oxidative stress, and total antioxidant power in Thai Brahman cattle. Twenty-one cattle were divided into three groups: cattle maintained under artificial shade, under tree shade, and without shade. On days 1, 7, 14, 21, and 28 of the experimental period, after the cattle were set in individual stalls for 2 h, physiological changes, thiobarbituric acid reactive substances (TBARS), and total antioxidant power were investigated. The results revealed that the respiratory rate, heart rate, sweat rate and the neutrophil/lymphocyte ratio of the no-shade cattle were significantly higher than those of cattle maintained under artificial shade and tree shade ( P total antioxidant power of the no-shade cattle was lower than those of cattle maintained under artificial shade and tree shade, but the total antioxidant power of cattle maintained under artificial shade and tree shade were not different ( P > 0.05). However, rectal temperature and packed cell volume of the cattle in all groups did not differ ( P > 0.05). These results showed that artificial shade and tree shade can protect cattle from sunlight compared to no shade, and that the effectiveness of tree shade for sunlight protection is at an intermediate level.

    Hepatocytes are involved in the endogenous and drug metabolism; many of the enzymes involved in those processes are incorporated into extracellular vesicles and secreted into the bloodstream. Liver-damaging conditions modify the molecular cargo of those vesicles significantly. However, no information about the effect of these hepatic vesicles on the extracellular environment is available. Drug-induced liver damage increases the number of circulating extracellular vesicles and affects the release and content of hepatocyte-derived vesicles. In this work, we evaluated the metabolic effect of these vesicles on the composition of the serum. We performed a targeted ultra-high performance liquid chromatography-mass spectrometry (UHPLC-MS) metabolomics analysis of serum samples. The samples had been first incubated with hepatic extracellular vesicles from hepatocytes challenged with acetaminophen or diclofenac. The incubation affected the serum levels of 67 metabolites, such as amino acids and different species of lipids. The metabolites included various species of phosphatidylcholines and phosphatidylethanolamines. These compounds are the components of biological membranes; our observations suggest that the vesicles might take part in remodelling and maintenance of the membranes. Alterations in the levels of some other serum metabolites might have deleterious consequences, for example, the tetracosanoic acid with its cardiovascular effects. However, some of the metabolites whose levels were increased, including alpha-linoleic and tauroursodeoxycholic acids, have been reported to have a protective effect. Our targeted metabolomics analysis indicated that the hepatic extracellular vesicles act as nano-metabolic machines supplying the extracellular environment with the means to integrate diverse tissue responses. In conclusion, we show that the hepatic extracellular vesicles are metabolically active and might play a role in the physiopathological response to hepatic insults

    Serum uric acid (SUA) is the end-product of purine metabolism in humans, and its levels often increase in subjects with metabolic syndrome (MetS). Despite several studies demonstrating a relationship between increased SUA levels and the prevalence of MetS, prospective data on SUA as a predictor of the incidence of MetS in the elderly are limited. Our aim was to conduct a prospective study on the association between SUA concentrations and the onset of MetS in an elderly Italian cohort. This is a cohort study (Progetto Veneto Anziani; Pro.V.A.) involving community-dwelling subjects aged ≥65 years and followed up for a mean 4.4 years. We included 1128 participants (aged 74.7 ± 7.1 years) without MetS at the baseline. Gender-specific SUA groups according to the standard deviation (SD) from the mean were considered, taking the incidence of MetS as the main outcome. The mean SUA level was significantly higher in men than in women (5.4 ± 1.2 vs. 4.5 ± 1.2 mg/dl; p < 0.0001). Over the 4.4-year follow-up, 496 individuals developed MetS. After adjusting for potential confounders, Cox's regression analysis revealed no relationship between higher baseline SUA concentrations and the incidence of MetS in men or in the sample as whole, while women with SUA levels more than 1 SD above the mean (≥5.7 mg/dl) carried a 58% higher risk (95%CI: 1.03-2.40; p = 0.03) of being newly diagnosed with MetS during the follow-up. High SUA levels significantly and independently predicted MetS in older women, but not in men, over a 4.4-year follow-up.

    Chemerin plays an important role in metabolic syndrome (MetS) including nonalcoholic fatty liver disease (NAFLD). L-carnitine (LC) may reduce plasma glucose, lipid profile, and improve liver function. The aim of the study was to assess serum chemerin in obese children with suspected NAFLD, the effect of LC on NAFLD grade, chemerin and metabolic profile. Fifty obese children were compared to 50 controls. All were subjected to anthropometric assessment, liver function, fasting lipid profile, glucose/insulin (G/I) ratio, homeostasis model assessment (HOMA) index, serum chemerin and abdominal ultrasonography before and after LC. Serum chemerin was higher in cases than controls. Eighty percent of cases had NAFLD with increase in chemerin as severity of NAFLD increased. There was a decrease in frequency of NAFLD and its severity after LC therapy. Noninvasive monitoring of serum chemerin in obese patients with suspected NAFLD could be used to diagnose NAFLD. LC supplementation is effective in treatment of NAFLD and reducing chemerin. Copyright © 2016 IMSS. Published by Elsevier Inc. All rights reserved.

    Physical activity is an important factor in attaining bone mass. Our aim was to investigate if low to moderate intensity exercise affects bone resorption [serum tartrate-resistant acid phosphatase (TRAP) 5b activity] and formation (serum osteocalcin concentration) in a randomized controlled exercise intervention trial in Finnish middle-aged men. In addition, the relations of these bone turnover markers with bone mineral density (BMD) and serum sex hormone concentrations [circulating testosterone (T), estradiol (E2), and sex hormone-binding globulin (SHBG) concentrations] were evaluated. Serum TRAP 5b activity and osteocalcin concentration were measured at randomization and after 1 and 4 years of the exercise intervention. BMDs of the lumbar spine (L2-L4), femoral neck, and total proximal femur were measured with a dual-energy X-ray absorptiometry (DXA). At randomization, TRAP 5b activity was strongly correlated with the osteocalcin concentration (Spearman r = 0.541, P bone turnover markers. After 1 year of exercise intervention, TRAP 5b activity was significantly lower in the exercise than reference group (P = 0.006). However, after 4 years of exercise intervention, the difference was no longer statistically significant. There were no differences in the osteocalcin concentrations between the study groups during the intervention. Our results show a connection between serum TRAP 5b activity and osteocalcin concentration. Furthermore, our results suggest that low to moderate exercise intervention and serum sex hormone concentrations may induce changes in bone metabolism in middle-aged men. However, exercise-induced effects on bone metabolism should be confirmed in other randomized controlled exercise trials taking into account exercise intensity and dose-response issues.

    The aim of the study was to explore the association between serum uric acid (SUA) and metabolic syndrome (MetS) in premenopausal and postmenopausal women in the Jinchang Cohort. We studied 3808 female Jinchuan Nonferrous Metals Corporation workers aged 40-60 years. Cohort data from epidemiological surveys and medical exams were used. MetS was defined using the 2009 Joint Interim Society criteria. The relationship between SUA and MetS was evaluated using multiple logistic regression after adjusting for potential confounders. MetS and hyperuricemia were more prevalent in postmenopausal women than premenopausal ones (35.3% versus 15.2% and 9.2% versus 4.2%, respectively). Premenopausal and postmenopausal women with hyperuricemia had 2.81 (95% CI: 1.72-4.61) and 2.10 (95% CI: 1.44-3.08), respectively, times the odds of having MetS than their counterparts without hyperuricemia. Even within normal SUA quartiles, only premenopausal women in the highest and second-highest quartile had 3.57 (95% CI: 2.24-5.68) and 2.78 (95% CI: 1.71-4.50), respectively, times the odds of having MetS than those in the lowest quartile. Even in the normal range, the odds ratios for MetS increased gradually according to SUA levels in all women (P trend  <   0.001). In conclusion, there was a significant correlation between SUA levels and MetS, and the association was stronger in premenopausal women than postmenopausal ones.

    An excess circulating uric acid level, even within the normal range, is always comorbid with metabolic syndrome (MS), several of its components, and nonalcoholic fatty liver disease (NAFLD), which was regarded as hepatic manifestation of MS; however, these associations remain controversial. This study aimed to quantitatively assess the relationship between the serum uric acid (SUA) levels and the MS/NAFLD risk. We searched for related prospective cohort studies including SUA as an exposure and MS/NAFLD as a result in MEDLINE (PubMed) and EMBASE databases up to January 31, 2015 and July 28, 2015, respectively. Pooled relative risks (RRs) and corresponding 95% confidence intervals (CIs) were extracted. A random-effects model was used to evaluate dose-response relationships. On the basis of 11 studies (54 970 participants and 8719 MS cases), a combined RR of 1.72 (95% CI, 1.45-2.03; P < .0001) was observed for the highest SUA level category compared with the lowest SUA level category. Furthermore, based on nine studies (51 249 participants and 8265 MS cases), dose-response analysis suggested that each 1 mg/dL SUA increment was roughly linearly associated with the MS risk (RR, 1.30; 95% CI, 1.22-1.38; P < .0001). Beyond that, SUA level increased NAFLD risk (RR, 1.46; 95% CI, 1.31-1.63). Each 1 mg/dL SUA level increment led to 21% increase in the NAFLD risk. This meta-analysis suggests that higher SUA levels led to an increased risk of MS regardless of the study characteristics, and were consistent with a linear dose-response relationship. In addition, SUA was also a causal factor for the NAFLD risk.

    Mass spectrometry-based metabolomics is a rapidly growing field in both research and diagnosis. Generally, the methodologies and types of instruments used for clinical and other absolute quantification experiments are different from those used for biomarkers discovery and untargeted analysis, as the former requires optimal sensitivity and dynamic range, while the latter requires high resolution and high mass accuracy. We used a Q-TOF mass spectrometer with two different types of pentafluorophenyl (PFP) stationary phases, employing both positive and negative ionization, to develop and validate a hybrid quantification and discovery platform using LC-HRMS. This dual-PFP LC-MS platform quantifies over 50 clinically relevant metabolites in serum (using both MS and MS/MS acquisitions) while simultaneously collecting high resolution and high mass accuracy full scans to monitor all other co-eluting non-targeted analytes. We demonstrate that the linearity, accuracy, and precision results for the quantification of a number of metabolites, including amino acids, organic acids, acylcarnitines and purines/pyrimidines, meets or exceeds normal bioanalytical standards over their respective physiological ranges. The chromatography resolved highly polar as well as hydrophobic analytes under reverse-phase conditions, enabling analysis of a wide range of chemicals, necessary for untargeted metabolomics experiments. Though previous LC-HRMS methods have demonstrated quantification capabilities for various drug and small molecule compounds, the present study provides an HRMS quant/qual platform tailored to metabolic disease; and covers a multitude of different metabolites including compounds normally quantified by a combination of separate instrumentation.

    Two trials were conducted with heifers to determine heat tolerance among temperate Bos taurus (Angus, Hereford), Bos indicus (Brahman), tropical Bos taurus (Senepol, Romosinuano), and the reciprocal crosses of Hereford and Senepol. Differences among breeds in temperament score, circulating concentrations of cortisol, and blood packed cell volume were also investigated. Trial 1 used 43 Angus, 28 Brahman, 12 Hereford, 23 Romosinuano, 16 Senepol, 5 Hereford x Senepol (H x S), and 5 Senepol x Hereford (S x H) heifers. Trial 2 used 36 Angus, 31 Brahman, 9 Hereford, 14 Senepol, 19 H x S, and 10 S x H heifers. On the hottest summer date in Trial 1, rectal temperature of Angus was greater (P Senepol, or Romosinuano. Rectal temperature and plasma cortisol were significantly less in Senepol than in Brahman, suggesting that the differences in rectal temperature between these breeds may be due to differences in stress response possibly related to differences in temperament. Reciprocal crosses of Hereford and Senepol had rectal temperatures nearly as low as that of Senepol and displayed substantial heterosis (-9.4%, P Senepol heifers, and Brahman had significantly slower respiration rates than Romosinuano or Senepol. On the hottest summer date in Trial 2, rectal temperature in Angus heifers was greater (P Senepol had rectal temperatures similar to that of Senepol, or heterosis for log10 rectal temperature was similar to that in Trial 1 (-9.8%, P Senepol, except that plasma cortisol was not different between Brahman and Senepol on the hottest summer date. On this date, rectal temperature did not differ between Brahman and Senepol, which supports the hypothesis that there is a relationship between response to stress and rectal temperature that helps explain differences in rectal temperature between Brahman and Senepol. The results of these trials demonstrate heat tolerance of the Senepol and Romosinuano, two Bos taurus breeds. Furthermore, the results suggest a substantial level

    To study relationships between the indicators of serum lipid composition (SLC) and the markers of acetylator (energy) status (AS) in women with coronary heart disease (CHD), stable exertional angina (SEA), metabolic syndrome (MS), type 2 diabetes mellitus (DM) (according to the data multivariate correlation analysis). One hundred and eight women aged 54.9 +/- 0.7 years with CHD, Functional Class I-III SEA, MS, and type 2 DM were examined. SLC was studied, by determining the levels of total cholesterol (TC), triglycerides (TG), low-density lipoprotein cholesterol (LDL-C), very low-density lipoprotein cholesterol (VLDL-C), high-density lipoprotein cholesterol (HDL-C), atherogenic coefficient (AC), triglyceride coefficient (TC) (TC=TG/HDL-C). AS markers, such as blood acetylation degree (BAD) and the total acetylating capacity of the body (TACB), were concurrently determined. Correlations of each individual indicator of a lipidogram (TC, TG, LDL-C, VLDL-C, HDL-C, AC, and TC) and an AS marker (BAD, TACB) were analyzed in tandem. Examination of the relationships between SLC the indicators and AS markers in women with CHD, MS, and type 2 DM could establish that the values of a variant, 90th percentiles of SLC indicators (TC, TG, LDL-C, VLDL-C, HDL-C, AC, and TC) showed a significant strong direct (positive) relationship to those of the variant, 90th percentiles of AS markers (BAD, TACB). A significant inverse (negative) correlation was found between the values of the 90th percentile of AS markers (BAD, TACB), as well as between the values of >90th percentile of SLC indicators (TC, TG, LDL-C, VLDL-C, HDL-C, AC, and TC) and those of markers (BAD, TACB). The heterogeneity in the association was ascertained between the values of 90th percentile/variant of SLC and AS markers. The genetic polymorphism of AS - the phenotypes of slow/fast/intermediate acetylators (a three modal distribution) was stated. Knowledge of the patterns of relationships between BAD/AS and the

    Elevated serum uric acid (UA) has been known to be associated with the prevalence of metabolic syndrome (MetS). However, no prospective studies have examined whether serum UA levels are actually associated with the development of MetS. We performed a prospective study to evaluate the longitudinal effects of baseline serum UA levels on the development of MetS. A MetS-free cohort of 14 906 healthy Korean men, who participated in a medical check-up program in 2005, was followed until 2010. MetS was defined according to the Joint Interim Statement of the International Diabetes Federation Task Force on Epidemiology and Prevention. Cox proportional hazards models were performed. During 52 466.1 person-years of follow-up, 2428 incident cases of MetS developed between 2006 and 2010. After adjusting for multiple covariates, the hazard ratios (95% confidence intervals) for incident MetS for the second, the third, and the fourth quartile to the first quartile of serum UA levels were 1.09 (0.92-1.29), 1.22 (1.04-1.44), and 1.48 (1.26-1.73), respectively (p for trend <0.001). These associations were also significant in the clinically relevant subgroup analyses. Elevated serum UA levels were independently associated with future development of MetS in Korean men during the 5-year follow-up period.

    Associations between metabolic syndrome (MetS) with serum adipokines and basal lipoprotein lipase mass (serum LPL) have not been extensively studied in elderly Asians, who in general have lower body mass index than European populations. A cross-sectional analysis was conducted including 159 community-living elderly Japanese women whose age averaged 77 years. MetS was defined by the modified National Cholesterol Education Program Adult Treatment Panel III criteria, but using a body mass index ≥25 kg/m(2) instead of waist circumference. Serum LPL, leptin, adiponectin, plasminogen activator inhibitor 1 (PAI-1), interleukin-6, tumor necrosis factor-alpha, and high-sensitivity C-reactive protein were measured. Both the presence of MetS and the number of MetS components were associated with higher homeostasis assessment of insulin resistance, serum levels of leptin, PAI-1, and tumor necrosis factor-alpha and with lower serum levels of LPL and adiponectin (all P independent of fat mass index and insulin resistance. Although proinflammatory, prothrombotic, and anti-inflammatory states were associated with MetS, higher PAI-1 was associated with MetS independent of fat mass index and insulin resistance in elderly Japanese women, in whom obesity is rare.

    The present study was conducted to investigate if differences exist in the seminal plasma protein profile from mature Brahman bulls using two methods of semen collection: internal artificial vagina (IAV) and electroejaculation (EEJ). Semen was collected four times from three bulls on the same day and parameters were assessed immediately post-collection. Seminal plasma proteins were evaluated by 2-D fluorescence difference gel electrophoresis and identified by mass spectrometry. Semen volume was greater (P < 0.05) for EEJ (4.6 ± 0.35 mL) than for IAV (1.86 ± 0.24 mL) but sperm concentration was greater in IAV (1505 ± 189 × 10(6) sperm/mL) than in EEJ samples (344 ± 87 × 10(6) sperm/mL). Sperm motility and the percentage of normal sperm were not different between treatments. Total concentration of seminal plasma proteins was greater for samples collected by IAV as compared to EEJ (19.3 ± 0.9 compared with 13.0 ± 1.8 mg/mL, P < 0.05; respectively). Based on 2-D gels, 22 spots had a greater volume (P < 0.05) in gels derived from IAV samples, corresponding to 21 proteins identified as transferrin, albumin, epididymal secretory glutathione peroxidase, among others. Thirty-three spots, corresponding to 26 proteins, had a greater volume (P < 0.05) in gels derived from EEJ samples. These proteins were identified as spermadhesin-1, Bovine Sperm Protin 1, 3 and 5 isoforms, angiogenin-1, alpha-1B-glycoprotein, clusterin, nucleobindin-1, cathepsins, spermadhesin Z13, annexins, among others. Thus, proteins in greater amounts in samples obtained by IAV and EEJ were mainly of epididymal origin and accessory sex glands, respectively. Copyright © 2015 Elsevier B.V. All rights reserved.

    Metabolic syndrome (MetS) is associated with an increased risk of major cardiovascular events. In women, increased serum uric acid (SUA) levels are associated with MetS and its components. However, whether baseline and changes in SUA predict incidence of MetS and its components remains unclear. The subjects comprised 407 women aged 71 ± 8 years from a rural village. We have identified participants who underwent a similar examination 11 years ago, and examined the relationship between baseline and changes in SUA, and MetS based on the modified criteria of the National Cholesterol Education Program's Adult Treatment Panel (NCEP-ATP) III report. Of these subjects, 83 (20.4%) women at baseline and 190 (46.7%) women at follow-up had MetS. Multiple linear regression analysis was performed to evaluate the contribution of each confounding factor for MetS; both baseline and changes in SUA as well as history of cardiovascular disease, low-density lipoprotein cholesterol, and estimated glomerular filtration ratio (eGFR) were independently and significantly associated with the number of MetS components during an 11-year follow-up. The adjusted odds ratios (ORs) (95% confidence interval) for incident MetS across tertiles of baseline SUA and changes in SUA were 1.00, 1.47 (0.82-2.65), and 3.11 (1.66-5.83), and 1.00, 1.88 (1.03-3.40), and 2.49 (1.38-4.47), respectively. In addition, the combined effect between increased baseline and changes in SUA was also a significant and independent determinant for the accumulation of MetS components (F = 20.29, p < 0.001). The ORs for incident MetS were significant only in subjects with age ≥ 55 years, decline in eGFR, and no baseline MetS. These results suggested that combined assessment of baseline and changes in SUA levels provides increased information for incident MetS, independent of other confounding factors in community-dwelling women.

    Full Text Available As there is conflicting evidence for the relationship between hepatitis B virus surface antigen (HBsAg positivity and the prevalence of metabolic syndrome (MetS, we performed a meta-analysis to investigate whether HBsAg positivity affects the incidence of MetS.Observational studies on the relationship between HBsAg positivity and MetS were obtained from PubMed, Web of Science, and the Cochrane Library in April 2016. The pooled odds ratios (ORs of MetS and its components (central obesity, increased fasting glucose, increased blood pressure, dyslipidemia for subjects with or without HBsAg positivity were synthesized. The standardized mean difference of MetS components between HBsAg-positive participants and healthy controls was calculated. Heterogeneity was explored with subgroup analysis and sensitivity analysis. Publication bias was detected using Egger's test and Begg's test.Thirty studies were eligible for meta-analysis. The MetS OR for HBsAg-positive participants was significantly decreased compared with the controls [OR = 0.80, 95% confidence interval (CI, 0.70-0.90]. The negative effect of HBsAg positivity on elevated triglycerides (OR = 0.62, 95% CI, 0.59-0.64 was strong, while that for increased fasting blood glucose was weak (OR = 0.94, 95% CI, 0.90-0.98. The pooled ORs of central obesity (OR = 0.97, 95% CI, 0.91-1.04, reduced high-density lipoprotein cholesterol (OR = 0.98, 95% CI, 0.83-1.14, and elevated blood pressure (OR = 1.00, 95% CI, 0.80-1.25 for HBsAg-positive participants were all not significantly different compared with the controls. No publication bias was detected.Serum HBsAg positivity is inversely associated with the prevalence of MetS. Among the five components of MetS, elevated triglycerides had the strongest inverse relationship with HBsAg positivity.

    Type-2 diabetes mellitus (DM) and Metabolic syndrome (MetS) are both associated with dyslipidemia which may lead to development of vascular complications. Adiponectin is an anti-inflammatory protein synthesized by the adipose tissue. There is controversy regarding the association of adiponectin with lipid profile. To evaluate the correlation between serum adiponectin concentration and metabolic profile in patients with type-2 DM. A single center cross-sectional study was conducted on 173 patients with type-2 DM (82 males and 91 females). Plasma adiponectin concentration, lipid profile, glucose profile, and anthropometric features were investigated. Insulin resistance was determined using Homeostasis model assessment (HOMA). Correlation of serum adiponectin with lipid profile of patients with type-2 DM was assessed. Adiponectin was negatively correlated with waist circumference (r = -0.16, P = 0.06) and positively with HbA1c (r = 0.19, P = 0.032), total cholesterol (r = 0.23, P = 0.017), LDL (r = 0.30, P = 0.001), SD-LDL (r = 0.41, P lipid profile. The results of the present study suggest that in patients with type-2 DM and MetS, lipid profile is strongly correlated with blood concentration of adiponectin. The strongest association was observed between serum adiponectin and LDL.

    Bull breeding soundness parameters, semen characteristics and sexual behavior were evaluated for effects on reproductive performance in single-sire beef herds. A total of 155 cow herds (Angus, 50 herds; Hereford, 40 herds; Brahman, 46 herds; and Senepol, 19 herds) bred to bulls of the same breed were observed for 8 yr. All bulls produced adequate quality semen and had scrotal circumference (SC)>or=30 cm. Reproductive performance was evaluated by the conception rate (CON), conception rate during the first 21 d of the breeding season (21dCON), mean calving date (MCD), and mean calving date of the first half of the herd to calve (HHCD). Correlations were determined between breeding soundness parameters and reproductive performance for all bulls combined, by breed, and by age. The Cp statistic was used to select models for the effects of parameters on CON, 21dCON, MCD and HHCD. Breeding season length and breed had significant effects. The percentages of normal cells, proximal droplets, detached heads and the semen score (motility plus percentage of normal cells) had a significant effect on CON when all bulls were considered. After the effect of season was deleted, the most significant parameter affecting CON in the Brahman was the percentage of detached sperm heads. In the Angus, motility was significantly correlated with all reproductive performance indices. In the Hereford, breeding soundness examination score (BSE) was positively correlated with 21dCON.

    An experiment was conducted to determine the effects of dietary supplementation of thymol, synbiotic (Biomin, IMBO) and their combination in laying hen diets on laying performance, egg quality and serum metabolic profile from 24 to 36 weeks of age. Treatment groups were fed on a control diet, the control diet supplemented with thymol (250 mg/kg), the control diet supplemented with synbiotic (250 mg/kg) or the control diet supplemented with a combination of thymol (250 mg/kg) and synbiotic (250 mg/kg). Supplementation of thymol and synbiotic, separately as well as combined, improved egg weight, egg production, egg mass and feed conversion ratio from 24 to 36 weeks of age. The eggs obtained from thymol, synbiotic or their combination treatments displayed higher values of shell thickness, Haugh unit and shell percentage compared to the control. Serum cholesterol significantly decreased in the single or combined form of thymol and synbiotic supplementation treatments.

    Full Text Available Objective  To explore the correlation of serum γ-glutamyltransferase (γ-GT level in normal range to metabolic syndrome (MS in middle-aged and elderly Chinese women. Methods  Female inhabitants aged ≥40 years in Nan'an community, Chongqing, were recruited to receive questionnaire interview and physical examination. Blood glucose, lipid, liver and kidney function profiles were also examined. A total of 1308 subjects were involved in our study, and they were divided into four groups according to the γ-GT quartiles. The correlation of MS prevalence, odds ratio and the relation of menopausal status with γ-GT level was analyzed. Results  As the quartile of serum γ-GT level increased, the multiple metabolic risk profiles tended to deteriorate, and the number of postmenopausal women increased gradually. From the first quartile to the fourth quartile of γ-GT level, the prevalence of MS was 22.5%, 27.4%, 42.7% and 58.5%, respectively (P<0.01. Compared with those subjects in the first quartile of γ-GT, the MS risks in the fourth quartile increased by 2.92-fold, central obesity by 2.31-fold, high triglycerides by 3.76-fold, hypertension by 1.84-fold, and hyperglycemia by 1.63 fold. The γ-GT levels increased significantly in proportion to the number of elements of MS (P<0.01. Multiple stepwise regression analysis showed that triglycerides, waist circumference, menopausal status, 2h postprandial blood glucose and body mass index were independent influencing factors of γ-GT levels. Conclusions  Serum γ-GT is an independent metabolic risk factor related to woman's menopausal status. An increased γ-GT level in normal range might imply an increased MS risk in middle-aged and elderly Chinese women.

    Although serum uric acid (sUA) is not a criterion for diagnosing metabolic syndrome (MetS), many studies have identified a positive association between sUA and MetS in patients of various ages and ethnicities. This association has not been fully established in the very elderly. Cross-sectional and longitudinal study. A total of 18,906 Chinese elderly aged 65 and older undergoing routine health checkups in Taiwan were enrolled. Modified Adult Treatment Panel III criteria were used to define MetS. All participants were further divided into nine groups with gender specification according to age (the young-old, 65 to 74; old-old, 75 to 84; and oldest-old, 85 and over) and sUA concentration tertile (males: sUAG1, 6.7 mg/dL; females: sUAG1, 5.9 mg/dL). A cross-sectional study was first performed to determine the correlation between sUA and MetS and its components. A longitudinal study then excluded subjects with MetS at baseline to explore the risk of MetS according to sUA levels in 3 age groups. In the cross-sectional study, we observed a graded, positive association between sUA and MetS components that diminished after age 75. Subjects with higher sUA levels had higher odds ratios (OR) for the occurrence of MetS in the young-old and old-old groups of both sexes (P<0.001) except sUAG2 males in the old-old group. However, the association diminished with age and only a higher OR was observed in sUAG2 males in the oldest-old group (OR, 3.38; 95% CI, 1.11-10.30; P = 0.032). In the longitudinal study, the Kaplan-Meier plot showed that higher sUA levels were associated with a higher risk of MetS in the young-old group of both genders (P < 0.001 sUAG3 vs. sUAG1 and sUAG2). Cox regression analysis further confirmed these results (young-old group: sUAG3 HR, 1.90; 95% CI, 1.42-2.54; P < 0.001; old-old group males: HR, 2.20; 95% CI, 1.04-4.65; P = 0.039; young-old females: HR, 1.83; 95% CI, 1.38 - 2.43; P < 0.001).

    Emerging evidence has shown that serum uric acid (SUA) elevation might cause metabolic derangements, including metabolic syndrome (MetS) and non-alcoholic fatty liver disease (NAFLD); however, magnitude of the risk has not been quantified. We searched PubMed, EMBASE, and ISI databases for relevant studies through 10 May 2015. Prospective studies reporting the risk of SUA elevation on the incidence of MetS/NAFLD were enrolled. Pooled HR of MetS was 1.55 (95%CI: 1.40-1.70) for the highest versus lowest SUA categories, and 1.05 (95%CI: 1.04-1.07) per incremental increased in SUA of 1 mg/dl. The pooled HR of MetS in younger women was higher than age-matched men and older women (1.17 vs. 1.05 and 1.04, respectively, P metabolic disorders for linear trend between its elevation and MetS/NAFLD incidence. SUA-lowering therapy is a potential strategy for preventing systemic/hepatic metabolic abnormalities.

    The aim of the study was to examine whether lean fish (LF), fatty fish (FF) and camelina sativa oil (CSO), a plant-based source of alpha-linolenic acid (ALA), differ in their metabolic effects in subjects with impaired glucose metabolism. Altogether 79 volunteers with impaired fasting glucose, BMI 25-36 kg/m2 , age 43-72 years, participated in a 12-week randomized controlled trial with four parallel groups, i.e. the FF (4 fish meals/week), LF (4 fish meals/week), CSO (10 g/day ALA) and control (limited intakes of fish and source of ALA) groups. The proportions of EPA and DHA increased in plasma lipids in the FF group, and the proportion of ALA increased in the CSO group (P < 0.0001 for all). In the CSO group total and LDL-cholesterol (C) concentrations decreased compared with the FF and LF groups, LDL-C/HDL-C and ApoB/ApoA-I ratios decreased compared with the LF group. There were no significant changes in glucose metabolism or markers of low-grade inflammation. A diet enriched in CSO improves serum lipid profile as compared with a diet enriched in FF or LF in subjects with impaired fasting glucose, with no differences in glucose metabolism or concentrations of inflammatory markers.

    We evaluated the effects of 2 commonly available strategies (plant stanol ester drink and 10 mg simvastatin) on coronary heart disease (CHD) risk variables in participants with metabolic syndrome. Metabolic syndrome patients are at increased risk to develop CHD, partly due to high triacylglycerol (TAG) and low HDL cholesterol (HDL-C) concentrations and a low-grade inflammatory profile. Effects of plant stanol esters on TAG concentrations in these participants are unknown. After a 3-wk run-in period in which individuals consumed placebo yogurt drinks and placebo capsules, participants were randomly divided into 4 groups: placebo (n = 9), simvastatin + placebo drink (n = 10), placebo + stanol drink (n = 9), and simvastatin + stanol drink (n = 8). After 9 wk, we evaluated the effects on serum lipids, low-grade inflammation, and endothelial dysfunction markers. In metabolic syndrome patients, stanol esters (2.0 g/d), simvastatin, or the combination lowered non-HDL-C by 12.8% (P = 0.011), 30.7% (P cholesterol ester transfer protein mass, FFA concentrations, and markers for low-grade inflammation or endothelial dysfunction. This study shows that in metabolic syndrome patients, plant stanol esters lower not only non-HDL-C, but also TAG. Effects on TAG were also present in combination with statin treatment, illustrating an additional benefit of stanol esters in this CHD risk population.

    Serum protein profiles were studied together with serum binding sites and capacity for L-thyroxine in dwarf and non-dwarf White Leghorn and White Rock breeds at ages 1 wk., 4 wks. and in laying hens. Serum protein profiles varied with breed, strain and age. The percent gamma-globulin fraction was greater (P less than .05) in dwarf 1 wk. old and laying hens of the White Leghorn breed when compared with the normals. The only difference found in the White Rock breed was a decreased level of albumin in dwarf laying hens. There were no significant differences in the capacity or sites of binding of L-thyroxine to serum proteins although greater amounts of L-thyroxine were bound to globulin fractions in the dwarf. The data were interpreted to suggest that changes in serum protein profiles may have been the result of hypothyroidism at the cellular level but there was no reason to suspect abnormal binding of thyroid hormones to be the cause of that hypothyroidism.

    The present study was designed to investigate the effect of bark of Pterocarpus santalinus, an ethnomedicinal plant, on blood glucose, plasma insulin, serum lipids and the activities of hepatic glucose metabolizing enzymes in streptozotocin-induced diabetic rats. Streptozotocin-induced diabetic rats were treated (acute/short-term and long-term) with ethyl acetate:methanol fractions of ethanolic extract of the bark of P. santalinus. Fasting blood glucose, HbA(1C), plasma insulin and protein were estimated before and after the treatment, along with hepatic glycogen, and activities of hexokinase, glucose-6-phosphatase, fructose-1,6-bisphosphatase and glucose-6-phosphate dehydrogenase. Further anti-hyperlipidemic activity was studied by measuring the levels of serum lipids and lipoproteins. Phytochemical analysis of active fraction showed the presence of flavonoids, glycosides and phenols. Biological testing of the active fraction demonstrated a significant antidiabetic activity by reducing the elevated blood glucose levels and glycosylated hemoglobin, improving hyperlipidemia and restoring the insulin levels in treated experimental induced diabetic rats. Further elucidation of mechanism of action showed improvement in the hepatic carbohydrate metabolizing enzymes after the treatment. Our present investigation suggests that active fraction of ethanolic extract of bark of P. santalinus decreases streptozotocin induced hyperglycemia by increasing glycolysis and decreasing gluconeogenesis.

    Current screening procedures for colorectal cancer are imperfect and highly invasive and result in increased mortality rates due to low compliance. The goal of the experiments reported herein is to identify potential blood-based biomarkers indicative of early stage intestinal cancers using the ApcMin/+ mouse model of intestinal cancer as an experimental system. Serum proteins from tumor-bearing ApcMin/+ mice were quantitatively compared to tumor-free Apc+/+ wild-type mice via in anima metabolic labeling with 14N/15N-labeled Spirulina algae and an LTQ Orbitrap mass spectrometer. Out of 1116 total serum proteins quantified, this study identified 40 that were differentially expressed and correlated with the increase in intestinal neoplasms. A subset of these differentially expressed proteins underwent a secondary quantitative screen using selected reaction monitoring-mass spectrometry with stable isotope-labeled peptides. Using both quantitative techniques, we identified MGAM and COL1A1 as downregulated and ITIH3 and F5 as upregulated in serum. All but COL1A1 were similarly differentially expressed in the mRNA of neoplastic colonic tissues of ApcMin/+ mice compared to normal wild-type tissue. These differentially expressed proteins identified in the ApcMin/+ mouse model have provided a set of candidate biomarkers for future validation screens in humans.

    Decreased HDL cholesterol (HDL-c) is considered as an independent risk factor of cardiovascular disease in metabolic syndrome (Mets). Wendan decoction (WDD), a famous clinical traditional Chinese medicine formula in Mets in China, which can obviously up-regulate serum HDL-c levels in Mets. However, till now, the molecular mechanism of up-regulation still remained unclear. In this study, an integrated approach that combined serum ABCA1 in vivo assay, QSAR modeling and molecular docking was developed to explore the molecular mechanism and chemical substance basis of WDD upregulating HDL-c levels. Compared with Mets model group, serum ABCA1 and HDL-c levels intervened by two different doses of WDD for two weeks were significantly up-regulated. Then, kohonen and LDA were applied to develop QSAR models for ABCA1 up-regulators based flavonoids. The derived QSAR model produced the overall accuracy of 100%, a very powerful tool for screening ABCA1 up-regulators. The QSAR model prediction revealed 67 flavonoids in WDD were ABCA1 up-regulators. Finally, they were subjected to the molecular docking to understand their roles in up-regulating ABCA1 expression, which led to discovery of 23 ABCA1 up-regulators targeting LXR beta. Overall, QSAR modeling and docking studies well accounted for the observed in vivo activities of ABCA1 affected by WDD. Copyright © 2017 Elsevier Ltd. All rights reserved.

    Extensive epidemiologic studies have shown that cardiovascular disease and the metabolic syndrome (MetS) are associated with serum concentrations of liver enzymes; however, fundamental characteristics of this relation are currently unknown. We aimed to explore the role of liver aminotransferases in nonalcoholic fatty liver disease (NAFLD) and MetS. Liver gene- and protein-expression changes of aminotransferases, including their corresponding isoforms, were evaluated in a case-control study of patients with NAFLD (n = 42), which was proven through a biopsy (control subjects: n = 10). We also carried out a serum targeted metabolite profiling to the glycolysis, gluconeogenesis, and Krebs cycle (n = 48) and an exploration by the next-generation sequencing of aminotransferase genes (n = 96). An in vitro study to provide a biological explanation of changes in the transcriptional level and enzymatic activity of aminotransferases was included. Fatty liver was associated with a deregulated liver expression of aminotransferases, which was unrelated to the disease severity. Metabolite profiling showed that serum aminotransferase concentrations are a signature of liver metabolic perturbations, particularly at the amino acid metabolism and Krebs cycle level. A significant and positive association between systolic hypertension and liver expression levels of glutamic-oxaloacetic transaminase 2 (GOT2) messenger RNA (Spearman R = 0.42, P = 0.03) was observed. The rs6993 located in the 3' untranslated region of the GOT2 locus was significantly associated with features of the MetS, including arterial hypertension [P = 0.028; OR: 2.285 (95% CI: 1.024, 5.09); adjusted by NAFLD severity] and plasma lipid concentrations. In the context of an abnormal hepatic triglyceride accumulation, circulating aminotransferases rise as a consequence of the need for increased reactions of transamination to cope with the liver metabolic derangement that is associated with greater gluconeogenesis and

    Full Text Available Leptin is the protein product of the obesity gene, which is produced in fat tissue. It was originally thought to be involved only in the regulation of food intake and energy balance. We aimed to investigate the relationship of serum leptin levels with bone mineral density (BMD and biochemical markers of bone turnover in patients on hemodialysis (HD. This study included 72 patients (43 males and 29 females, whose mean age was 55.1 ± 11.4 years, mean body mass index was 23.13 ± 2.75 kg/m 2 and mean duration on HD was 5 ± 3.4 years. The BMD values were calculated using dual-energy X-ray absorptiometry (DEXA at the femoral neck and lumbar spine. Blood samples were taken for leptin, intact parathyroid hormone (I-PTH, bone alkaline phosphatase (BAP, calcium (Ca, phosphate (P and albumin. The leptin levels were higher in females than in males (22.3 ± 19.6 vs 20.8 ± 23, but this difference was not significant. The serum leptin level had a strong positive correlation with Ca levels in the female patients (r = 0.659 and P = 0.01 and a negative correlation with albumin levels (r = -0.461 and P = 0.01. No correlation was found with age, BMI, duration on dialysis, BMD and serum levels of PTH, BAP and P for the entire patient group or either gender separately. The serum leptin level was significantly lower in females with PTH >300 pg/mL when compared with patients with PTH = 100-300 pg/mL (86 ± 85 vs 47 ± 48 (P = 0.011.Women with BAP <300 IU/L had significantly higher serum leptin than those with BAP 300-600 IU/L (P = 0.024. Women with Ca <8.5 mg/dL had significantly lower serum leptin levels compared with those with Ca levels of 8.5-10.5 mg/dL (P = 0.011. There was no significant difference between the two genders among variables such as age, BMI, duration on dialysis, serum leptin, I-PTH, Ca, P, BAP, albumin and BMD of the femoral neck and lumbar spine.

    Metabolic bone disease may appear as a complication of obesity surgery. Because an imbalance in the osteoprotegerin and receptor-activator of nuclear factor-κB ligand system may underlie osteoporosis, we aimed to study this system in humans in the metabolic bone disease occurring after obesity surgery. In this study we included sixty women with a mean age of 47 ± 10 years studied 7 ± 2 years after bariatric surgery. The variables studied were bone mineral density, β-isomer of C-terminal telopeptide of type I collagen cross-links (a bone resorption marker), the bone formation markers osteocalcin and N-terminal propeptide of procollagen 1, serum osteoprotegerin and receptor-activator of nuclear factor-κB ligand. Serum osteoprotegerin inversely correlated with the bone remodeling markers osteocalcin, β-isomer of C-terminal telopeptide of type I collagen cross-links and N-terminal propeptide of procollagen 1. The osteoprotegerin and receptor-activator of nuclear factor-κB ligand ratio also correlated inversely with serum parathormone and osteocalcin. Bone mineral density at the lumbar spine was associated with age (β = -0.235, P = 0.046), percentage of weight loss (β = 0.421, P = 0.001) and osteoprotegerin and receptor-activator of nuclear factor-κB ligand ratio (β = 0.259, P = 0.029) in stepwise multivariate analysis (R 2  = 0.29, F = 7.49, P osteoprotegerin and receptor-activator of nuclear factor-κB ligand system is associated with bone markers and bone mineral density at the lumbar spine after obesity surgery.

    The newly identified adipokine chemerin has been shown to be associated with the components of MetS, inflammation and insulin resistance. In this study, the relationship between serum chemerin levels and the presence and severity of coronary artery disease (CAD) was evaluated in patients with MetS. The study population consisted of 84 MetS patients (43 patients with CAD and 41 without CAD), who had coronary angiography for suspected coronary artery disease, and 46 healthy individuals as a control group. Angiographic CAD was defined as ≥ 50% luminal diameter stenosis of at least one major epicardial coronary artery. The severity of CAD was determined by the Gensini score. Serum chemerin levels were measured with enzyme linked immunosorbent assay (ELISA). Serum chemerin levels were significantly higher in patients with MetS (n=84) than those in the control group (120.47±25.32 vs. 90.4±11.4 ng/ml P < 0.001). In addition, MetS patients with CAD had higher chemerin levels than MetS patients without CAD (128.7±26.6 vs. 115.7±15.2 ng/ml, P < 0.001). Serum chemerin levels had a significant positive correlation with the Gensini score (r=0.58, P < 0.001). Multivariate logistic regression demonstrated that serum high-density lipoprotein cholesterol (HDL-C) and chemerin levels were significant and independent predictors for determining the presence of angiographic CAD (OR=1.009, 95% CI: 0.972-1.057; P=0.003 and OR=0.925, 95% CI: 0.896-0.922; P < 0.001, respectively). This study demonstrated that in patients with MetS, chemerin levels were higher in patients with CAD than patients without CAD and also showed a significant positive correlation with CAD severity.

    Over the last decade, much evidence emerged to suggest that alterations in maternal diets during pregnancy may irreversibly affect aspects of physiological and biochemical functions in the fetus. To explore the effects of maternal dietary treatments with dehydroepiandrosterone (DHEA) on lipid metabolism in the embryo, we investigated serum lipid profile and hepatic lipid metabolism-related gene expression in the maternal and embryonic chicken. Sixteen-week-old pullets were allocated into 3 groups (n=30), and after laying, they were provided with a commercial diet supplemented with DHEA at 0, 20 or 100mg/kg diet. Eggs were collected after DHEA treatment and incubated at 37.5 degrees C and a relative humidity of 60%. Blood and liver samples were collected from hens and embryonic chickens. DHEA treatment resulted in decreased body weight and increased relative liver weight in both maternal and embryonic chickens, while the concentrations of blood triglyceride (TG), total cholesterol (TC), low-density lipoprotein-cholesterol (LDL-C) and non-esterified fatty acid (NEFA) were significantly lower in the 20mg DHEA/kg group as compared to the control group during embryonic development. The expression of acetyl CoA carboxylase (ACC) and carnitine palmitoyl transferase I (CPTI) gene was also reduced following treatment with 20mg DHEA/kg at hatching. However, blood TC, and hepatic fatty acid synthase (FAS) and hydroxy methylglutaryl-CoA reductase (HMGR) gene expression were significantly up-regulated in the 100mg DHEA/kg group during embryonic development and hatching. Overall, the results of this study indicate that maternal dietary treatment with DHEA regulates serum lipid metabolism and hepatic gene expression. 2010 Elsevier Inc. All rights reserved.

    Serum amyloid A (SAA) is a sensitive marker of inflammation and its elevation has been implicated in obesity and in cardiovascular disease, yet data on its regulation in young adults or on its role in early atherosclerosis is scarce. We investigated which factors explain the variation in SAA and analysed whether SAA could be associated with preclinical atherosclerosis. Serum amyloid A levels were measured in participants of the Cardiovascular Risk in Young Finns Study (n = 2280, n = 1254 women, n = 1026 men). Correlates and determinants of SAA were analysed and the effect of SAA on subclinical atherosclerosis, measured as intima-media thickness (IMT) and carotid artery compliance, was evaluated with risk-factor adjusted models. Serum amyloid A correlated directly and independently of BMI with C-reactive protein (CRP), waist circumference and leptin in both sexes, with total cholesterol, LDL cholesterol and ApolipoproteinA1 (ApoA1) in women and with triglycerides, insulin levels and insulin resistance in men. Use of combined oral contraceptives and intrauterine device was also associated with SAA levels. Determinants for SAA included CRP, leptin and ApoA1 in women, and CRP, leptin and HDL cholesterol in men. SAA levels correlated with carotid compliance in both sexes and with IMT in men, yet SAA had no independent effect on IMT or carotid compliance in multivariable analysis. Serum amyloid A was associated with several metabolic risk factors but was not an independent predictor of IMT or carotid artery compliance. Further longitudinal studies will show whether SAA holds a prognostic value as a risk marker, analogously to CRP.

    Myopia is becoming increasingly common globally and is associated with potentially sight-threatening complications. Spending time outdoors is protective, but the mechanism underlying this association is poorly understood. To examine the association of myopia with ultraviolet B radiation (UVB; directly associated with time outdoors and sunlight exposure), serum vitamin D concentrations, and vitamin D pathway genetic variants, adjusting for years in education. A cross-sectional, population-based random sample of participants 65 years and older was chosen from 6 study centers from the European Eye Study between November 6, 2000, to November 15, 2002. Of 4187 participants, 4166 attended an eye examination including refraction, gave a blood sample, and were interviewed by trained fieldworkers using a structured questionnaire. Myopia was defined as a mean spherical equivalent of -0.75 diopters or less. Exclusion criteria included aphakia, pseudophakia, late age-related macular degeneration, and vision impairment due to cataract, resulting in 371 participants with myopia and 2797 without. Exposure to UVB estimated by combining meteorological and questionnaire data at different ages, single-nucleotide polymorphisms in vitamin D metabolic pathway genes, serum vitamin D3 concentrations, and years of education. Odds ratios (ORs) of UVB, serum vitamin D3 concentrations, vitamin D single-nucleotide polymorphisms, and myopia estimated from logistic regression. Of the included 3168 participants, the mean (SD) age was 72.4 (5) years, and 1456 (46.0%) were male. An SD increase in UVB exposure at age 14 to 19 years (OR, 0.81; 95% CI, 0.71-0.92) and 20 to 39 years (OR, 0.7; 95% CI, 0.62-0.93) was associated with a reduced adjusted OR of myopia; those in the highest tertile of years of education had twice the OR of myopia (OR, 2.08; 95% CI, 1.41-3.06). No independent associations between myopia and serum vitamin D3 concentrations nor variants in genes associated with vitamin D

    Full Text Available Abstract Low serum 25 hydroxyvitamin D3 (vitamin D3 is known to perturb cellular function in many tissues, including the endocrine pancreas, which are involved in obesity and type II diabetes mellitus (TIIDM. Vitamin D3 insufficiency has been linked to obesity, whether obesity is assessed by body mass index (BMI or waist circumference (waist. Central obesity, using waist as the surrogate, is associated with the metabolic syndrome (MetSyn, insulin resistance, TIIDM and atherosclerotic cardiovascular disease (CVD. We tested how vitamin D3 was related to measures of fat mass, MetSyn markers, haemoglobin A1c (HbA1c and MetSyn in a cross-sectional sample of 250 overweight and obese adults of different ethnicities. There were modest inverse associations of vitamin D3 with body weight (weight (r = -0.21, p = 0.0009, BMI (r = -0.18, p = 0.005, waist (r = -0.14, p = 0.03, [but not body fat % (r = -0.08, p = 0.24], and HbA1c (r = -0.16, p = 0.01. Multivariable regression carried out separately for BMI and waist showed a decrease of 0.74 nmol/L (p = 0.002 in vitamin D3 per 1 kg/m2 increase in BMI and a decrease of 0.29 nmol/L (p = 0.01 per 1 cm increase in waist, with each explaining approximately 3% of the variation in vitamin D3 over and above gender, age, ethnicity and season. The similar relationships of BMI and waist with vitamin D3 may have been due to associations between BMI and waist, or coincidental, where different mechanisms relating hypovitaminosis D3 to obesity occur concurrently. Previously reviewed mechanisms include that 1 low vitamin D3, may impair insulin action, glucose metabolism and various other metabolic processes in adipose and lean tissue 2 fat soluble-vitamin D3 is sequestered in the large adipose compartment, and low in serum, 3 obese people may be sensitive about their body shape, minimising their skin exposure to view and sunlight (not tested. We showed evidence for the first theory but no evidence to support the second. In

    The objective was to determine the relationship between seminal plasma proteins and sperm morphology in Bos indicus bulls of the Brahman breed. Fifty-six 24-month-old Australian Brahman bulls were electroejaculated and samples were examined to determine the percentage of morphologically normal sperm (PNS24) and the seminal plasma protein composition was identified and quantified by 2-D gel electrophoresis. The total integrated optical density of 152 seminal plasma protein spots (SPPs) across all gels was determined using the PDQuest software version 8.0 (Bio Rad, USA). Using a single regression mixed model with the density of individual spots as a covariate for PNS24, 17 SPPs were significantly associated with PNS24 (psperm morphology.

    Full Text Available We studied cell death by apoptosis and necrosis in cardiac remodeling produced by Trypanosoma cruzi infection. In addition, we evaluated collagen I, III, IV (CI, CIII and CIV deposition in cardiac tissue, and their relationship with serum levels of procollagen type I carboxy-terminal propeptide (PICP and procollagen type III amino-terminal propeptide (PIIINP. Eight infected and two uninfected guinea pigs were necropsied at seven time points up to one year post-infection. Cell death by necrosis and apoptosis was determined by histopathological observation and terminal deoxynucleotidyl transferase dUTP nick end labeling, respectively. Deposition of cardiac collagen types was determined by immunohistochemistry and serum levels of PICP, PIIINP, and anti-T. cruzi IgG1 and IgG2 by ELISA. IgG2 (Th1 response predominated throughout the course of infection; IgG1 (Th2 response was detected during the chronic phase. Cardiac cell death by necrosis predominated over apoptosis during the acute phase; during the chronic phase, both apoptosis and necrosis were observed in cardiac cells. Apoptosis was also observed in lymphocytes, endothelial cells and epicardial adipose tissue, especially in the chronic phase. Cardiac levels of CI, CIII, CIV increased progressively, but the highest levels were seen in the chronic phase and were primarily due to increase in CIII and CIV. High serum levels of PICP and PIIINP were observed throughout the infection, and increased levels of both biomarkers were associated with cardiac fibrosis (p = 0.002 and p = 0.038, respectively. These results confirm the role of apoptosis in cell loss mainly during the chronic phase and the utility of PICP and PIIINP as biomarkers of fibrosis in cardiac remodeling during T. cruzi infection.

    Full Text Available Abstract Background Patients with diabetes already fulfill one diagnostic criterion for MS according to the existing classifications. Our aim was to identify one single clinical parameter, which could effectively predict the presence of MS in patients with type 2 diabetes. Methods We studied all patients with type 2 diabetes who attended our Diabetes Outpatient Clinic during a three-month period. Waist circumference, blood pressure and serum lipids were measured. Establishment of MS diagnosis was based a on National Cholesterol Education Program Adult Treatment Panel III (NCEP ATP III criteria and b on International Diabetes Federation (IDF criteria. Receiver operating characteristic (ROC analysis was applied in order to identify the clinical parameter with the highest predictive capability for MS. Among the 500 participating patients (231 males, 269 females, MS was diagnosed in 364 patients (72.8% according to the NCEP ATP III criteria and in 408 patients (81.6% according to the IDF criteria. Results For the NCEP ATP III classification, serum triglycerides (in the overall population, waist and HDL (in female population demonstrated the highest predictive capability for MS (AUCs:0.786, 0.805 and 0.801, respectively. For the IDF classification, no single parameter reached an AUC > 0.800 in the overall population. In females, HDL displayed a satisfactory predictive capability for MS with an AUC which was significantly higher than the one in males (0.785 vs. 0.676, respectively, p Conclusion Elevated serum triglycerides strongly indicate the presence of MS in patients with type 2 diabetes. In female patients with type 2 diabetes, central obesity was the second stronger predictor of MS besides hypertriglyceridemia.

    Full Text Available The objective of the present study was to investigate the effects of methionine (Met supplementation on growth performance of cubs, nutrient digestibility, nitrogen metabolism and serum biochemical parameters of female blue foxes. One hundred primiparous female blue foxes that were similar in breeding date, pedigree, age, and weight were selected for the trial. The foxes were randomly assigned to four groups (n = 25 each group and fed diets supplemented with Met at 2 (Met2, 4 (Met4, 6 (Met6 and 8 g/kg (Met8, respectively, for 40 days. Our data showed that body weights at 20 and 40 d were significantly higher in the Met4 group than in the Met2 group (P < 0.05. The Met4 group also had the highest apparent digestibility of dry matter and crude protein compared with either the Met2, Met6, or Met8 group (P < 0.05. The serum Met and isoleucine (Ile concentrations were significantly higher in the Met4 group than in the Met6 or Met8 group (P < 0.05. In summary, these data indicate that supplementary Met improves growth performance of cubs likely due to increased crude protein and dry matter and increased nitrogen retention of female blue foxes. The optimal amount of Met supplementation is 10 g/kg basal diet.

    Treatment with antiepileptic drugs is commonly guided by serum level monitoring. Such monitoring requires expensive laboratory equipment and products. However, well-conducted studies on the cost-effectiveness of therapeutic drug monitoring for antiepileptic drugs are lacking particularly in patients with structural-metabolic epilepsy. The study aims to assess the cost-effectiveness of serum level monitoring services in the management of children with structural-metabolic epilepsy during the first year of diagnosis. A retrospective cost-effectiveness analysis was conducted from the provider perspective. It included patients attended a paediatric neurology clinic. The effectiveness measures used in this analysis were the number of patients that achieved ≥50% reduction in seizure frequency, and the number of patients with 3-month seizure free. Medical records of the patients were reviewed for the required information. Medical chart/billing data obtained from the hospital were collected to estimate the resources used (One Malaysian Ringgit MYR is equivalent to 0.31 USD). The recruited children were followed for one year following their first visit. The average cost effectiveness ratio for the monitored patients (MYR 2735 per patient that achieved a ≥50% reduction in seizure frequency) was lower than that for non-monitored patients (MYR 2921 per patients that achieved a ≥50% reduction in seizure frequency), with incremental cost-effectiveness ratio of MYR 2357 per one additional patient that achieved a ≥50% reduction in seizure frequency. The average cost effectiveness ratios for monitored and non-monitored group were MYR 8279 and MYR 6433 per patient with a 3-month seizure-free period, respectively, with incremental cost-effectiveness ratio of MYR 29,666 per one additional patient with a 3-month seizure-free period. In terms of the effectiveness measures used, serum level monitoring of antiepileptic drugs was found to be cost-effective. However, the incremental

    The impact of metabolic phenotypes on the association of uricemia with urinary albumin/creatinine ratio (uACR) remains unresolved. We evaluated the association between serum uric acid and uACR in persons with 0, and 1-2 metabolic syndrome (MetS) components and determined the modification effects of visceral adiposity index (VAI), mean arterial pressure (MAP), and fasting glucose on this association. Using data from a cross-sectional survey of a representative Czech population aged 25-64 years (n = 3612), we analyzed 1,832 persons without decreased glomerular filtration rate uric acid levels only in persons with 1-2 MetS components (standardized beta (Sβ) 0.048; P = 0.024); however, not in those without any component (Sβ 0.030; P = 0.264). Uric acid levels increased by the interaction of uACR with VAI (Sβ 0.06; P = 0.012), and of uACR with MAP (Sβ 0.05; P = 0.009). Finally, the association of uACR with uricemia was confined to persons whose VAI together with MAP were ≥the median of 1.35 and 98mm Hg, respectively (Sβ 0.190; P < 0.001). We demonstrated a strong modification effect of VAI and MAP on the association between uACR and uricemia, which suggests obesity-related hypertension as the underlying mechanism.

    Oxidative stress has been reported to be involved in the pathogenesis of metabolic disorders related with obesity. The aim of the study was to investigate the association of oxidative stress and paraoxonase activities with non-alcoholic fatty liver disease (NAFLD) as well as metabolic syndrome. A total of 109 obese children and adolescents and 44 healthy and lean control subjects were enrolled in the study. According to their ultrasonographic steatosis scores, they were classified into four groups as follows: healthy children; obese, non-NAFLD; obese, grade I-NAFLD; and obese, grade II-III NAFLD. The biochemical parameters and insulin resistance (HOMA-IR) were evaluated from fasting samples. The plasma total antioxidant status (TAS), total oxidant status (TOS), and serum paraoxonase activities were measured and then oxidative stress index (OSI) was calculated as the indicator of degree of oxidative stress. As the steatosis increased, the alanine aminotransferase, C-reactive protein, HOMA-IR, total cholesterol, and LDL cholesterol increased, whereas HDL cholesterol decreased. The TAS measurements were higher in the obese NAFLD group compared with that of the healthy control group. The TOS and OSI measurements did not differ between the groups. Paraoxonase activities increased significantly as steatosis increased. Among the children in this study, no relationship could be demonstrated between obesity with/without steatosis and oxidant/antioxidant status.

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

    Postgenomics research and development is witnessing novel intersections of omics data intensive technology and applications in health and personalized nutrition. Chief among these is the nascent field of nutri-metabolomics that harnesses metabolomics platforms to discern person-to-person variations in nutritional responses. To this end, differences in the origin and ripening stage of fruits might have a strong impact on their phytochemical composition, and consequently, on their potential nutri-metabolomics effects on health. The objective of the present study was to evaluate the effects of a 4-week cross-over nutritional intervention on the metabolic status of 24 young healthy subjects. The intervention was carried out with two tomato sauces differing in their natural lycopene content, which was achieved by using tomatoes harvested at different times. Blood samples were drawn from each subject before and after each intervention period. Aqueous and lipid extracts from serum samples were analyzed by 1H-NMR metabolic profiling combined with analysis of variance simultaneous component analysis (ASCA) and multilevel simultaneous component analysis (MSCA). These methods allowed the interpretation of the variation induced by the main factors of the study design (sauce treatment and time). The levels of creatine, creatinine, leucine, choline, methionine, and acetate in aqueous extracts were increased after the intervention with the high-lycopene content sauce, while those of ascorbic acid, lactate, pyruvate, isoleucine, alanine were increased after the normal-lycopene content sauce. In conclusion, NMR-based metabolomics of aqueous and lipid extracts allowed the detection of different metabolic changes after the nutritional intervention. This outcome might partly be due to the different ripening state of the fruits used in production of the tomato sauces. The findings presented herein collectively attest to the emergence of the field of nutri-metabolomics as a novel

After 1 month of therapy, the number of children with normal alkaline phosphatase activity (P < 0.05, osteocalcin (P < 0.05, collagen type 1 C-telopeptides (P < 0.05 increased; in 3 months — total calcium (P < 0.05, 25(OHD (P < 0.05. Conclusions. The use of vitamin D3 and calcium solution normalizes bone metabolism parameters in children with bronchial asthma. The optimal time to control the effectiveness of medical recovery of bone metabolism in children with bronchial asthma is 3 months.

    Background Metabolic syndrome is defined by a clustering of cardiovascular risk factors and is associated with a heightened inflammatory state. A raised serum high-sensitivity C-reactive protein, a marker of inflammation, is also known to associate with cardiovascular risk. We have investigated the relationship between the presence of metabolic syndrome and serum high-sensitivity C-reactive protein concentration in a large representative Persian population cohort without a history of cardiovascular disease. Methods The MASHAD study population cohort comprised 9778 subjects, who were recruited from the city of Mashhad, Iran, between 2007 and 2008. Several cardiovascular risk factors were measured in this population without cardiovascular disease. Individuals were categorized into quartiles of serum high-sensitivity C-reactive protein concentration: first quartile - 0.72 (0.59-0.85) (median [range]) mg/L, second quartile - 1.30 (1.14-1.4) mg/L, third quartile - 2.29 (1.92-2.81) mg/L and fourth quartile - 6.63 (4.61-11.95) mg/L, respectively. The prevalence of metabolic syndrome in each quartile was determined using either International Diabetes Federation or Adult Treatment Panel III criteria. Results The prevalence of metabolic syndrome was highest in the fourth quartile for serum high-sensitivity C-reactive protein (1220 subjects [50.0%]), and significantly higher than that in the first quartile (reference group) (634 subjects [25.9%]) ( P cardiovascular disease in our Persian cohort.

A cross-sectional study was conducted on 2053 Uygur residents, 2219 Kazak residents and 2656 Han residents aged 30-80, all with prediabetic syndromes. The pre-dialectic patients were divided into three groups for analysis on metabolic features and inter-group comparisons. (1)In total, 1934 pre-diabetic cases (28.3%)were diagnosed, with the highest prevalence (31.6%) seen in Uygurs and the lowest (25.5%) in Kazaks and medium (27.0%) in Hans. Data from the inter-group comparison showed statistically significant differences (P = 0.00). (2)Prevalence of high LDL-C was 80.5% , with hyperuricemia as 30.3% and MS as 58.3% , while the inter-group comparison did not show any statistically significant differences (P > 0.05). (3) Prevalence of pre-diabetic when combined with hypertension or earlier-stage hypertension, reached 88.0%, with the highest (96.8%) among Kazak group, 85.1% in Uygurs and 83.7% in Han population. Data from the inter-group comparison showed statistically significant difference(χ(2) = 59.959, P = 0.00). (4)The overall prevalence of prediabetic, when combined with obesity was 35.4%, with 29.6% in Han, 36.8% in Uygur and 41.0% in Kazak groups. Data from the inter-group comparison showed statistically significant difference(χ(2) = 19.097, P = 0.00). According to results from this cross-sectional study regarding the metabolic features of Uygur, Kazak and Han prediabetic groups, differences were seen in the prevalence rates of pre-diabetic among Uygur, Kazak and Han ethnic groups, with the highest seen in Uygurs and the lowest in Kazaks. Hyperlipidemia, hypertension, hyperuricemia,MS and obesity were commonly seen in all the prediabetic groups, with the highest prevalence of hypertension seen in the Kazak group and the highest rate of obesity in Uygur group.

    Full Text Available BACKGROUND: Vitamin D may play a protective role in many diseases. Public health messages are advocating sun avoidance to reduce skin cancer risk but the potential deleterious effects of these recommendations for vitamin D metabolism have been poorly investigated. METHODOLOGY/PRINCIPAL FINDINGS: We investigated the association between 25-hydroxy-vitamin D (25(OHD, skin type and ultraviolet exposure in 1414 Caucasian females in the UK. Mean age of the cohort was 47 years (18-79 and mean 25(OHD levels were 77 nmol/L (6-289. 25(OHD levels were strongly associated with season of sampling with higher levels in the spring and summer months (p<0.0001. Light skin types (skin type 1 and 2 have lower levels of 25(OHD (mean 71 nmol/L compared to darker skin types (skin type 3 and 4 (mean 82 nmol/L after adjusting for multiple confounders (p<0.0001. The trend for increasing risk of low vitamin D with fairer skin types was highly significant despite adjustment for all confounders (p = 0.001. CONCLUSIONS/SIGNIFICANCE: Contrary to previous studies across different ethnic backgrounds, this study within Caucasian UK females shows that fair skin types have lower levels of 25(OHD compared to darker skin types with potential detrimental health effects. Public health campaigns advocating sun avoidance in fair skinned individuals may need to be revised in view of their risk of vitamin D deficiency.

    Metabolic syndrome (MetS) is a health problem throughout the world and is associated with cardiovascular disease and diabetes. Thus, the purpose of the present work was to evaluate the effects of a dietary pattern (DP; soy protein, nopal, chia seed, and oat) on the biochemical variables of MetS, the AUC for glucose and insulin, glucose intolerance (GI), the relationship of the presence of certain polymorphisms related to MetS, and the response to the DP. In this randomized trial, the participants consumed their habitual diet but reduced by 500 kcal for 2 wk. They were then assigned to the placebo (P; n = 35) or DP (n = 32) group and consumed the reduced energy diet plus the P or DP beverage (235 kcal) minus the energy provided by these for 2 mo. All participants had decreases in body weight (BW), BMI, and waist circumference during the 2-mo treatment (P < 0.0001); however, only the DP group had decreases in serum TG, C-reactive protein (CRP), and AUC for insulin and GI after a glucose tolerance test. Interestingly, participants in the DP group with MetS and the ABCA1 R230C variant had a greater decrease in BW and an increase in serum adiponectin concentration after 2 mo of dietary treatment than those with the ABCA1 R230R variant. The results from this study suggest that lifestyle interventions involving specific DP for the treatment of MetS could be more effective if local foods and genetic variations of the population are considered.

    To examine the effects of supervised aerobic exercise training on serum adiponectin and lipids, including triglyceride (TG)-rich lipoproteins, in moderate dyslipidemic subjects. Twenty-five dyslipidemic patients [mean body mass index (BMI)=24.6 kg/m²; mean age= 39 years; mean total cholesterol=226 mg/dL; mean TG=149 mg/dL] without metabolic syndrome, diabetes, and hypertension underwent supervised aerobic exercise training (60 min/day, 2 to 3 times/week) at an intensity of 60-80% of age-predicted maximal heart rate for 16 weeks. Lipoprotein cholesterol levels were measured by our established anion-exchange HPLC method. Aerobic exercise training significantly decreased BMI, cholesterol levels of LDL- and IDL-, and markedly reduced VLDL-cholesterol at week 8 (-45%) and week 16 (-50%), but changes in TG and HDL-cholesterol were not significant. Adiponectin significantly increased by 51% and HOMA-R was significantly decreased at week 16, although changes in these parameters were not significant at week 8. There was no significant relationship between changes in adiponectin and in VLDL- or IDL- cholesterol, but changes in adiponectin were inversely but insignificantly associated with changes in BMI (r=-0.343, p=0.095). These results suggest that supervised aerobic exercise training two to three times/week in the presence of body weight loss increases serum adiponectin with an improved lipid profile and insulin sensitivity at week 16 in non-obese moderate dyslipidemic patients, and that VLDL-cholesterol is markedly decreased by supervised aerobic exercise training.

    Full Text Available OBJECTIVES: Low serum 25-hydroxyvitamin D (25OHD level has been associated with an increased risk of several chronic diseases. Our aim was to determine lifestyle and clinical factors that are associated with 25OHD level and to investigate connection of 25OHD level with metabolic and cardiovascular disease markers. DESIGN: In total, 2868 Finnish men and women aged 45-74 years participated in FIN-D2D population-based health survey in 2007. Participants that had a serum sample available (98.4%; n = 2822 were included in this study. 25OHD was measured with chemiluminescent microparticle immunoassay method. RESULTS: The mean 25OHD level was 58.2 nmol/l in men (n = 1348 and 57.1 nmol/l in women (n = 1474. Mean 25OHD level was lower in the younger age groups than in the older ones (p<0.0001 both in men and women. This study confirmed that low physical activity (p<0.0001 both in men and women, smoking (p = 0.0002 in men and p = 0.03 in women and high BMI (p<0.0001 in women are factors that independently associate with low 25OHD level. Of the metabolic and cardiovascular disease markers high triglyceride concentration (p = 0.02 in men and p = 0.001 in women and high apolipoprotein B/apolipoprotein A1 ratio (p = 0.04 in men and p = 0.03 in women were independently associated with low 25OHD level. CONCLUSIONS: Higher age did not predict lower 25OHD level in this study population of aged 45-74 years which may derive from a healthy life-style of "active pensioners". Low physical activity and smoking came up as independent lifestyle factors associated with low 25OHD level. Defining the molecular mechanisms behind the associations of 25OHD with low physical activity and smoking are important objective in future studies. The association of 25OHD with BMI, high triglyceride concentration and apolipoprotein B/apolipoprotein A1 ratio may be related to the role of vitamin D in inflammation, but more detailed studies are needed.

    Inorganic arsenic (As) is methylated via one carbon metabolism (OCM) to mono- and dimethylated arsenicals (MMA and DMA), facilitating urinary excretion. Hyperhomocysteinemia (HHcys), a marker of impaired OCM, is a risk factor for As-induced skin lesions, but the influences of single nucleotide polymorphisms (SNPs) in OCM genes on Hcys, As metabolism and skin lesion risk is unclear. To (i) explore genetic sources of Hcys and the causal role of HHcys in As-induced skin lesion development using OCM genetic proxies for HHcys and (ii) identify OCM SNPs associated with urinary As metabolite proportions and/or skin lesion incidence. We conducted a case-control study nested in the Health Effects of Arsenic Longitudinal Study (HEALS) in Bangladesh which 876 incident skin lesion cases were matched to controls on sex, age, and follow-up time. We measured serum Hcys, urinary As metabolites, and 26 SNPs in 13 OCM genes. Serum Hcys and urinary %DMA were independently associated with increased and decreased odds of skin lesions, respectively. The T allele of MTHFR 677 C ➔ T (rs1801133) was associated with HHcys, higher %MMA, and lower %DMA, but not with skin lesions. Interactions between SNPs and water As on skin lesion risk were suggestive for three variants: the G allele of MTRR rs1801394 and T allele of FOLR1 rs1540087 were associated with lower odds of skin lesions with lower As (≤50 μg/L), and the T allele of TYMS rs1001761 was associated with higher odds of skin lesions with higher As. While HHcys and decreased %DMA were associated with increased risk for skin lesions, and MTHFR 677 C ➔ T was a strong predictor of HHcys, MTHFR 677 C ➔ T was not associated with skin lesion risk. Future studies should explore (i) non-OCM and non-genetic determinants of Hcys and (ii) if genetic findings are replicated in other As-exposed populations, mechanisms by which OCM SNPs may influence the dose-dependent effects of As on skin lesion risk.

    The correlations between synaptophysin (SYP) plasma levels and the brain neurotransmission activity are still not strictly identified. However, the efficiency of neurotransmission depends, inter alia, on the age, hormonal status, and coexistence of a low-grade systemic inflammation (LGSI) which is regarded as a pathogenic link with obesity and insulin resistance, atherogenesis and aging per se. The aim of this study was to investigate the associations between synaptophysin serum levels and age, LGSI indices, homocysteine and selected hormonal parameters (dehydroepiandrosterone and its sulfate, free-testosterone, SHBG) and the prevalence of metabolic syndrome (MS) in men over the age of 40. After randomization, 157 male volunteers aged 40-80 years were included in a retrospective study. MS was diagnosed according to the International Diabetes Federation criteria. For the diagnosis of late-onset hypogonadism (LOH) we adopted the criteria proposed by the European Male Aging Study (EMAS). Synaptophysin plasma concentrations in respondents decreased with age, but only between the ages of 40 to 70 years. There were no differences in SYP plasma concentrations in men suffering from MS compared to healthy subjects (p=0.845). Men suffering from MS demonstrated while higher hs-CRP (high sensitive C - reactive protein) levels than healthy (p=0.019), contrary to the α1-antichymotrypsin and transferrin. A positive monotonic correlation between synaptophysin and hs-CRP was demonstrated (r=0.235; p=0.003). No statistically significant relationships between SYP and homocysteine plasma levels were presented (r=0.047; p=0.562), although in men diagnosed with MS higher homocysteine levels compared to healthy subjects were demonstrated. No correlations between synaptophysin and free testosterone (r=-0.036; p=0.651), DHEA (r=-0.122; p=0.128) and its sulphate (r=-0.024; p=0.764) as well as SHBG (r=-0.088; p=0.288) were demonstrated.

    To evaluate whether uric acid (UA) predicts 4-yr incidence of metabolic syndrome (MetS) in non-diabetic participants of the Strong Heart Study (SHS) cohort. In this population-based prospective study we analyzed 1499 American Indians (890 women), without diabetes or MetS, controlled during the 4th SHS exam and re-examined 4 years later during the 5th SHS exam. Participants were divided into sex-specific tertiles of UA and the first two tertiles (group N) were compared with the third tertile (group H). Body mass index (BMI = 28.3 ± 7 vs. 31.1 ± 7 kg/m(2)), fat-free mass (FFM = 52.0 ± 14 vs. 54.9 ± 11 kg), waist-to-hip ratio, HOMA-IR (3.66 vs. 4.26), BP and indices of inflammation were significantly higher in group H than in group N (all p < 0.001). Incident MetS at the time of the 5th exam was more frequent in group H than group N (35 vs. 28%, OR 1.44 (95% CI = 1.10-1.91; p < 0.01). This association was still significant (OR = 1.13, p = 0.04) independently of family relatedness, sex, history of hypertension, HOMA-IR, central adiposity and renal function, but disappeared when fat-free mass was included in the model. In the SHS, UA levels are associated to parameters of insulin resistance and to indices of inflammation. UA levels, however, do not predict incident MetS independently of the initial obesity-related increased FFM. Copyright © 2014 Elsevier B.V. All rights reserved.

    Background Vitamin D may play a protective role in many diseases. Public health messages are advocating sun avoidance to reduce skin cancer risk but the potential deleterious effects of these recommendations for vitamin D metabolism have been poorly investigated. Methodology/Principal Findings We investigated the association between 25-hydroxy-vitamin D (25(OH)D), skin type and ultraviolet exposure in 1414 Caucasian females in the UK. Mean age of the cohort was 47 years (18–79) and mean 25(OH)D levels were 77 nmol/L (6–289). 25(OH)D levels were strongly associated with season of sampling with higher levels in the spring and summer months (p<0.0001). Light skin types (skin type 1 and 2) have lower levels of 25(OH)D (mean 71 nmol/L) compared to darker skin types (skin type 3 and 4) (mean 82 nmol/L) after adjusting for multiple confounders (p<0.0001). The trend for increasing risk of low vitamin D with fairer skin types was highly significant despite adjustment for all confounders (p = 0.001). Conclusions/Significance Contrary to previous studies across different ethnic backgrounds, this study within Caucasian UK females shows that fair skin types have lower levels of 25(OH)D compared to darker skin types with potential detrimental health effects. Public health campaigns advocating sun avoidance in fair skinned individuals may need to be revised in view of their risk of vitamin D deficiency. PMID:19649299

    The purpose of this study was to evaluate whether the apolipoprotein B/apolipoprotein A-I (apoB/apoA-I) ratio is a promising risk predictor of metabolic syndrome (MetS) and to determine the optimal cut-off value of this ratio in detecting subjects with MetS in a Chinese population. A prospective study was conducted using a representative sample of non-institutionized people in Taiwan. A total of 3,343 participants with mean age (±SD) of 39.86 (±15.61) years old were followed up from 2002 to 2007. The primary outcome was the incidence of MetS. The MetS was defined according to a unified criterion established by several major organizations. There were 462 cases of incident MetS during a mean follow-up period of 5.26 years. A significantly stepwise increase in the incidence of MetS across quartiles of the apoB/apoA-I ratio was noted in both sexes after adjustment for potential confounders (p for trend risk of MetS in both men [adjusted hazard ratio (HR) = 6.29, 95 % confidence interval (CI) = 2.79-9.13] and women (adjusted HR = 3.82, 95 % CI = 1.06-6.63). Comparisons of receiver operating characteristics curves indicated that the predictive ability of apoB/apoA-I ratio to detect MetS was better than conventional lipid ratio measurements. Furthermore, the optimal cut-off value of apoB/apoA-I ratio for MetS diagnosis was 0.71 in men and 0.56 in women. These results suggest that an elevated apoB/apoA-I ratio might constitute a potentially crucial measure linked to the risk of developing MetS.

    Full Text Available Background: More than 90 tyrosine kinases have been implicated in the pathogenesis of malignant transformation and tumor angiogenesis. Tyrosine kinase inhibitors (TKIs have emerged as effective therapies in treating cancer by exploiting this kinase dependency. The TKI erlotinib targets the epidermal growth factor receptor (EGFR, whereas sunitinib targets primarily vascular endothelial growth factor receptor (VEGFR and platelet-derived growth factor receptor (PDGFR.TKIs that impact the function of non-malignant cells and have on- and off-target toxicities, including cardiotoxicities. Cardiotoxicity is very rare in patients treated with erlotinib, but considerably more common after sunitinib treatment. We hypothesized that the deleterious effects of TKIs on the heart were related to their impact on cardiac metabolism. Methods: Female FVB/N mice (10/group were treated with therapeutic doses of sunitinib (40 mg/kg, erlotinib (50 mg/kg, or vehicle daily for two weeks. Echocardiographic assessment of the heart in vivo was performed at baseline and on Day 14. Heart, skeletal muscle, liver and serum were flash frozen and prepped for non-targeted GC-MS metabolomics analysis. Results: Compared to vehicle-treated controls, sunitinib-treated mice had significant decreases in systolic function, whereas erlotinib-treated mice did not. Non-targeted metabolomics analysis of heart identified significant decreases in docosahexaenoic acid (DHA, arachidonic acid (AA/ eicosapentaenoic acid (EPA, O-phosphocolamine, and 6-hydroxynicotinic acid after sunitinib treatment. DHA was significantly decreased in skeletal muscle (quadriceps femoris, while elevated cholesterol was identified in liver and elevated ethanolamine identified in serum. In contrast, erlotinib affected only one metabolite (spermidine significantly increased. Conclusions: Mice treated with sunitinib exhibited systolic dysfunction within two weeks, with significantly lower heart and skeletal muscle

    Full Text Available Abstract Background Under-carboxylated osteocalcin (ucOC, the precursor substrate of bone biomarker OC is a potent regulator of energy metabolism by promoting insulin production and adiponectin synthesis and decreasing fat stores. The aim of the present study was to point out the potential role of ucOC in the physiopathology of polycystic ovary syndrome (PCOS, a common disorder defined by the constellation of anovulation, insulinresistance, hyperinsulinemia, obesity and androgen excess. Methods In this prospective case–control investigation, 78 young premenopausal women, i.e. 52 PCOS patients and 26 age- and body mass index (BMI-matched healthy controls, were successively enrolled. Recruitment of PCOS patients was performed according to Androgen Excess-Polycystic Ovary Syndrome (AE-PCOS Society 2006 criteria. All study participants were subjected to clinical examination, whole-body composition assessment and measurements of serum ucOC, OC (1-49, glucose and lipids, insulin, total testosterone (TT, estradiol, sex-hormone binding globulin (SHBG, high-sensitivity C-reactive protein (Hs-CRP and β-CrossLaps. Results BMI-stratified multivariate analysis revealed significantly higher ucOC levels in PCOS vs. controls in lean (p = 0.001 but not overweight and obese study participants (p = 0.456. Notably, a positive correlation between ucOC and TT (p = 0.018, calculated free testosterone (cFT, p = 0.028 and serum insulin (p = 0.036, respectively, was found to be confined to the lean analysis subgroup. Furthermore, in stepwise multiple regression models, β-CrossLaps and cFT were able to predict 46.71% of serum ucOC variability. (1-43/49OC failed to be significantly associated to any PCOS trait. Conclusions Circulating ucOC concentration is related to key endocrine PCOS characteristics in a weight-dependent manner. Within the bone-pancreas loop, high ucOC may favor insulin release in lean hyperandrogenic women to compensate for

    Since the association between serum uric acid (SUA) and metabolic syndrome (MetS) has been reported extensively, it remains unclear whether SUA is associated with MetS and its components in a Chinese Yi population. This study recruited 1,903 people (912 men, 991 women) older than 18 years old from the Liangshan region in Sichuan province. Anthropometric measurements and biochemical indexes were measured by a standard protocol. SUA levels were divided into four quartiles by sex. The prevalence of hyperuricemia and MetS is 21.0% and 17.1%, respectively. The levels of SUA were positively correlated with waist circumference, body mass index and triglycerides while negatively correlated with high-density lipoprotein cholesterol in both sexes. Increased SUA levels were accompanied with prevalence of MetS and several components in both sexes (P < 0.05). Men with the highest SUA quartile had an increased risk of MetS [OR (95% CI): 3.101 (1.281-7.504)], and men with higher SUA levels had an increased risk of central obesity, high blood pressure and hypertriglyceridemia compared to the lowest SUA quartile. Women with higher SUA levels had an increased risk of MetS, central obesity, hypertriglyceridemia and a lower risk of high blood pressure compared to the lowest SUA quartile. SUA levels were closely associated with MetS and several components by sex in Chinese Yi population.

    It is controversial whether serum uric acid (SUA) is a risk factor for the prevalence of metabolic syndrome (MetS). The current study was designed to highlight the association of SUA and MetS and its components. Data on 3675 healthy male subjects, aged 17-88 years, were collected for the cross-sectional study. A representative sample of 2575 individuals who did not suffer from MetS at baseline was involved in the cohort study. A cox regression model was applied to evaluate causality for the 2- and 4-year large scale longitudinal study. In the cross-sectional analysis, SUA showed a statistically significant negative correlation with high-density lipoprotein cholesterol (HDL-c) and a positive correlation with blood pressure (BP), triglycerides (TG), waist circumference (WC), and body mass index (BMI) (all P<0.001). In longitudinal analysis, examining the risk of developing MetS, SUA concentrations (hazard ratios comparing fourth quartile to the first quartile of 1.75; 95% CI, 1.26-2.41) were positively associated with incident MetS after adjusted for age, blood pressure, glucose, TG, HDL-c, smoking, alcohol drinking and education. SUA is positively correlated with the prevalence of MetS. Increased SUA concentration may be an independent risk factor for MetS. Copyright © 2015. Published by Elsevier B.V.

    Serum uric acid (SUA) is associated with many cardiovascular risk factors such as hypertension (HTN) and metabolic syndrome (MetS). However, the association of SUA with atherosclerosis remains controversial. Our aim was to investigate the relationships of SUA with HTN, MetS and atherosclerosis in Chinese inpatients with type 2 diabetes. This cross-sectional study was performed with a sample of 2388 hospitalized Chinese patients with type 2 diabetes. Both carotid and lower limb atherosclerotic lesions were assessed for intima-media thickness, plaque and stenosis by Doppler ultrasound. Atherosclerotic plaque and stenosis were defined as the presence of either carotid or lower limb plaques and stenoses, respectively. There were significant increases in the prevalence of both HTN and MetS across the SUA quartiles (HTN: 43.4, 49.6, 56.1 and 66.3% for the first, second, third and fourth quartiles, respectively, P uric acid in atherosclerosis might be attributable to other cardiovascular risk factors, such as HTN and MetS.

    Sixteen Holstein cows were assigned to 2 groups to evaluate the caloric and metabolic effect of feeding marine algae (ALG) from 3 wk prepartum until 12 wk postpartum. Milk production characteristics and the profiles of hormones and metabolites in the serum were monitored from -7 to 46 d in milk (DIM) and in follicular fluid (FF) from 14 to 46 DIM. All cows received a corn- and grass silage-based partially mixed ration supplemented with concentrate and protein supplement. In the diet of the ALG group, 2 kg of the concentrate was replaced by a concentrate containing ALG (44 g/d of docosahexaenoic acid). Diets were isocaloric (net energy basis) and equal in intestinal digestible protein. The ALG diet increased milk yield (41.2 vs. 38.2 kg/d) and decreased milk fat yield (1.181 vs. 1.493 kg/d) and milk fat content (31.6 vs. 40.7 g/kg). Protein yield (1.336 vs. 1.301 kg/d) was not affected but a tendency toward decreased milk protein content (32.8 vs. 34.7 g/kg) was observed. Marine algae supplementation increased the β-hydroxybutyric acid (BHBA) concentration in FF of the ALG cows compared with that in the controls (0.992 vs. 0.718 mmol/L). The total protein concentration in FF was decreased in ALG (62.9 vs. 67.6 g/L). Plasma and serum metabolites did not significantly differ between treatments except for a tendency toward a lower concentration of urea in the serum of the control compared with ALG (4.69 vs. 5.13 mmol/L). Based on metabolizable energy calculations, a daily energy-sparing effect of 3.48 Mcal was obtained due to milk fat depression (MFD). The concomitant increase in milk yield suggests that at least part of this spared energy is used to stimulate milk production. Theoretically, 3.48 Mcal of ME could lead to an increase in milk yield of 7.43 kg/d, which is higher than the observed 3 kg/d. However, when evaluating nutrient requirements during MFD in early lactation, we calculated that increased milk production is caused by a propionate-saving effect of 2

    The objectives of this study were to determine the fraction of additive genetic variance explained by the SNP from the Illumina Bovine3K chip; to compare the ranking of animals evaluated with genomic-polygenic, genomic, and polygenic models; and to assess trends in predicted values from these 3 models for residual feed intake (RFI), daily feed intake (DFI), feed conversion ratio (FCR), and postweaning BW gain (PWG) in a multibreed Angus-Brahman cattle population under subtropical conditions. Data consisted of phenotypes and genotypes from 620 bulls, steers, and heifers ranging from 100% Angus to 100% Brahman. Phenotypes were collected in a GrowSafe automated feeding facility (GrowSafe Systems, Ltd., Airdrie, Alberta, Canada) from 2006 to 2010. Variance components were estimated using single-trait genomic-polygenic mixed models with option VCE (Markov chain Monte Carlo) of the program GS3. Fixed effects were contemporary group (year-pen), age of dam, sex of calf, age of calf, Brahman fraction of calf, and heterozygosity of calf. Random effects were additive SNP, animal polygenic, and residual effects. Genomic predictions were computed using a model without polygenic effects and polygenic predictions with a model that excluded additive SNP effects. Heritabilities were 0.20 for RFI, 0.31 for DFI, 0.21 for FCR, and 0.36 for PWG. The fraction of the additive genetic variance explained by SNP in the Illumina 3K chip was 15% for RFI, 11% for DFI, 25% for FCR, and 15% for PWG. These fractions will likely differ in other multibreed populations. Rank correlations between genomic-polygenic and polygenic predictions were high (0.95 to 0.99; P calves with greater Brahman fraction were more efficient but grew more slowly than calves with greater Angus fraction. Predicted SNP values were small for all traits, and those above and below 0.2 SNP SD were in multiple chromosomes, supporting the contention that quantitative traits are determined by large numbers of alleles with small

    Full Text Available Background: Zinc (Zn and copper (Cu may play a pivotal role in the pathogenesis of diabetes and diabetic complications by mediating oxidative stress. Both Zn deficiency and excess of Cu are associated with an increased risk of type 2 diabetes and cardiovascular disease. We aimed to investigate the relationships between serum Zn/Cu ratio and glycemic status, renal function, and metabolic parameters in patients with and without type 2 diabetes.Methods: We conducted a cross-sectional study on 355 subjects (149 type 2 diabetic and 206 non-diabetic in whom serum Zn and Cu levels were measured at the same time. Associations between serum Zn/Cu ratio and clinical data were evaluated using multiple regression analysis. We also evaluated associations between serum Zn/Cu ratio and the prevalence of type 2 diabetes and glycemic control by multivariate logistic regression analysis.Results: Serum Zn/Cu ratio was positively associated with estimated glomerular filtration rate after adjustment for BMI (β = 0.137, P = 0.014. Plasma B-type natriuretic peptide levels were negatively associated with serum Zn/Cu ratio after adjustment for age, sex, and BMI (β = −0.258, P = 0.032. In patients with type 2 diabetes, serum Zn/Cu ratio was negatively associated with plasma HbA1c levels after adjustment for age, sex, and BMI (β = −0.239, P = 0.003. In addition, multivariate logistic regression analysis revealed that the highest quartile of serum Zn/Cu ratio was associated with a reduced risk of poor (HbA1c ≥ 7% glycemic control odds ratio = 0.382; 95% confidence interval (CI, 0.165–0.884; P = 0.025 in patients with type 2 diabetes.Conclusion: Serum Zn/Cu ratio was favorably associated with renal function in all subjects and glycemic control in patients with type 2 diabetes. The Zn/Cu ratio, in addition to the individual serum levels of trace elements, is important for metabolism in humans.

    To examine the associations of food consumption, serum vitamins and metabolic syndrome risk with physical activity level in middle-aged adults. Cross-sectional. National Health and Nutrition Examination Survey (NHANES) 2005-2006. Adults aged 40-70 years were divided into three groups by tertile of accelerometer-determined steps/d (in men and women, respectively): tertile 1 (sedentary), active), ≥10699, ≥9226. The active men consumed more grain products, fruits and vegetables, whereas the active women consumed more legumes and vegetables, compared with the sedentary group. Serum vitamin concentrations were associated with daily steps in both men and women. Vitamin C, α-carotene, trans-β-carotene, cis-β-carotene, β-cryptoxanthin, lutein+zeaxanthin, lycopene, γ-tocopherol and vitamin D were significantly associated with daily steps. OR (Pmetabolic syndrome in men and women, respectively. Those with the highest steps taken showed a more healthful eating profile and a better serum vitamin profile compared with less active adults. Those with the lowest steps taken had greater odds of having metabolic syndrome and its risk components. Probably, daily walking is a marker of a healthful eating profile and increasing daily walking is one of the healthful ways to decrease the metabolic syndrome and its risk components.

    Full Text Available Amyloid β (Aβ deposition has been implicated in the pathogenesis of Alzheimer’s disease. However, the early effect of Aβ deposition on metabolism remains unclear. In the present study, thus, we explored the metabolic changes in the hippocampus and serum during first 2 weeks of Aβ25–35 injection in rats by using an integrated method of NMR-based metabolomics and ANOVA-simultaneous component analysis (ASCA. Our results show that Aβ25–35 injection, time, and their interaction had statistically significant effects on the hippocampus and serum metabolome. Furthermore, we identified key metabolites that mainly contributed to these effects. After Aβ25–35 injection from 1 to 2 weeks, the levels of lactate, N-acetylaspartate, creatine, and taurine were decreased in rat hippocampus, while an increase in lactate and decreases in LDL/VLDL and glucose were observed in rat serum. Therefore, we suggest that the reduction in energy and lipid metabolism as well as an increase in anaerobic glycolysis may occur at the early stage of Aβ25–35 deposition.

    Brain-derived neurotrophic factor (BDNF) plays a role in energy homeostasis. However, the postprandial BDNF change has not been well investigated. We hypothesized that the BDNF increment after oral glucose challenge is associated with body weight.To address this possibility, man adults with obesity in conjunction with metabolic syndrome were compared with normal weight controls at baseline in the initial cross-sectional protocol. The obese subjects then underwent a 12-week program for body-weight reduction in the prospective protocol. The area under the curve (AUC) of serum BDNF was recorded during a 75 g oral glucose tolerant test and the BDNF AUC index was defined as [(AUC of BDNF) - (fasting BDNF2 hours)]/(fasting BDNF2 hours).A total of 25 controls and 36 obese subjects completed the study assessments. In the cross-sectional protocol, the BDNF AUC index was significantly higher in the obese subjects than in the controls (9.0 ± 16.5% vs. - 8.0 ± 22.5%, P = 0.001). After weight reduction (from 97.0 ± 12.5 kg to 88.6 ± 12.9 kg, P body weight was significantly associated with the BDNF AUC index after the study (95% CI between 0.21 and 1.82, P = 0.015). Using 6% weight reduction as a cut-off value, a larger weight reduction was able to reliably predict a negative BDNF AUC index.In conclusion, a high BDNF AUC index was observed for obese men in this study, whereas the index value significantly decreased after body-weight reduction. These findings suggest that postprandial BDNF increment may be associated with obesity.

    Metabolic syndrome (MetS) is a major risk factor for cardiovascular disease and diabetes. Previous studies in obese children demonstrating a positive association between serum uric acid (sUA) and components of MetS are confounded by lack of uniformity in age and pubertal status of children. Therefore, we have examined the role of sUA in MetS and its components in pre-pubertal children (Tanner Stage I, age ≤ 9 years). Pre-pubertal obese children (32 boys, 27 girls, age 6-9 years) were recruited from Nuevo Leon, Mexico. For comparison, an equal number of children with normal body mass index (BMI) in the same age range (22 Boys, 39 girls, age 6-9 years) were also recruited from the same community. Presence of MetS and its components was defined according to the criteria of International Diabetes Federation. Fasting blood was analyzed for lipids, glucose, insulin, and uric acid. Among the obese children, sUA was positively associated with insulin resistance and hypertriglyceridemia and negatively associated with high density lipoprotein-cholesterol (HDLc). Subjects were three times more likely to have a MetS diagnosis per one unit (md/dL) difference in sUA. Of the 59 obese pre-pubertal children, 20 were classified as having MetS defined by the presence of abdominal obesity and two or more of other components described under methods. Of these, 57.1% (20/61) had sUA between 5.1 and 7.1 mg/dl. The findings of this study clearly indicate a positive relationship between uric acid and MetS and its components in pre-pubertal obese children with Tanner stage I and ≤9 years of age.

    To explore the association between serum uric acid (SUA) levels, metabolic syndrome (MetS) and cardiovascular disease (CVD) in patients treated with lipid-lowering agents from multiple centers in China. We investigated 15,478 participants who had been documented with recorded SUA in the DYSlipidemia International Study which included 25,697 patients, aged 45 years old or older, who were treated with lipid-lowering agents from 122 centers between April 2012 and October 2012. Logistic regression analysis was performed to examine the association between SUA levels, MetS and CVD. After adjusting for multi-variables, hyperuricemia (the highest category of SUA level) showed a significantly higher risk of MetS compared to the lowest category[according to NCEP-ATPIII criteria, odds ratio (OR) 1.51, 95 % confidence interval (CI) (1.30,1.74) in men, OR 2.35 95 % CI (2.00,2.75) in women; and according to IDF criteria, OR 1.40 95 % CI (1.20,1.63) in men, OR 1.65 95 % CI (1.41,1.94) in women]. In addition, elevated SUA concentration was shown to be associated with coronary heart disease (CHD) (OR 1.26 95 % CI (1.09, 1.45) in men, and OR 1.27, 95 % CI (1.07, 1.50) in women) and heart failure (HF) (OR 1.61 95 % CI (1.15, 2.24) in men, and OR 1.91, 95 % CI (1.29, 2.82) in women). Our research suggested a positive association between SUA levels and MetS in Chinese patients receiving lipid-lowering therapy. Elevated SU levels were positively associated independently of measured confounders to CHD and HF.

    The independent role of serum uric acid (SUA) as a marker of cardio-renal risk is debated. The aim of this study was to assess the relationship between SUA, metabolic syndrome (MS), and other cardiovascular (CV) risk factors in an Italian population of hypertensive patients with a high prevalence of diabetes. A total of 2429 patients (mean age 62 ± 11 years) among those enrolled in the I-DEMAND study were stratified on the basis of SUA gender specific quartiles. MS was defined according to the NCEP-ATP III criteria, chronic kidney disease (CKD) as an estimated GFR (CKD-Epi) <60 ml/min/1.73 m(2) or as the presence of microalbuminuria (albumin-to-creatinine ratio ≥2.5 mg/mmol in men and ≥3.5 mg/mmol in women). The prevalence of MS, CKD, and positive history for CV events was 72%, 43%, and 20%, respectively. SUA levels correlated with the presence of MS, its components, signs of renal damage and worse CV risk profile. Multivariate logistic regression analysis revealed that SUA was associated with a positive history of CV events and high Framingham risk score even after adjusting for MS and its components (OR 1.10, 95% CI 1.03-1.18; P = 0.0060; OR 1.28, 95% CI 1.15-1.42; P < 0.0001). These associations were stronger in patients without diabetes and with normal renal function. Mild hyperuricemia is a strong, independent marker of MS and high cardio-renal risk profile in hypertensive patients under specialist care. Intervention trials are needed to investigate whether the reduction of SUA levels favorably impacts outcome in patients at high CV risk. Copyright © 2014 Elsevier B.V. All rights reserved.

    Fertility traits are economically important in cattle breeding programs. Scrotal circumference (SC) measures are repeatable, easily obtained, highly heritable, and positively correlated with female fertility traits and sperm quality traits in males. A useful approach to summarize SC measures over time is using nonlinear models, which summarize specific measures of SC in a few parameters with biological interpretation. This approach facilitates the selection of bulls with larger SC and maturity index (K), that is, early maturing animals. Because SC is a sex-limited trait, identifying the underlying genomics of growth curve parameters will allow selection across both males and females. We reported the first multitrait genomewide association study (GWAS) of estimated growth curve parameters for SC data in Brahman cattle. Five widely used nonlinear models were tested to fit a total of 3,612 SC records, measured at 6, 12, 18, and 24 mo of age. The von Bertalanffy model, individually fitted for each animal, best fit this SC data. Parameter estimates SC at maturity (A) and K as well as SC at all ages were jointly analyzed in a GWAS to identify 1-Mb regions most strongly associated with each trait. Heritabilities were 0.25 for K and 0.32 for A and ranged from 0.51 to 0.72 for SC at 6 (SC6), 12 (SC12), 18 (SC18), and 24 mo of age (SC24). An overlapping window on chromosome 14 explaining around 0.8% of genetic variance for K, SC12, SC18, and SC24 was observed. The major positional candidate genes within 1 Mb upstream and downstream of this overlapping window were , , , and . Windows of 1 Mb explaining more than 0.4% of each trait on chromosomes 1, 3, 6, 7, 14, 17, 18, 24, 25, and 26 were identified. Pathways and net-work analyses were indicated through transcription factors playing a role on fertility traits: , , , , , , and . Further validation studies on larger populations or other breeds are required to validate these findings and to improve our understanding of the

    Roselle (Hibiscus sabdariffa L.) is a plant with antihyperlipidemic and antihypertensive effects. This study aimed to evaluate the effects of roselle calyces on the serum levels of lipids and insulin, inflammation, and oxidative stress in patients with metabolic syndrome (MetS). Forty adult patients with MetS were randomly assigned to receive either 500 mg of H. sabdariffa calyx powder or placebo once daily for 4 weeks. Systolic and diastolic blood pressures (SBP and DBP) and BMI (body mass index) as well as fasting serum levels of glucose (FPG; fasting plasma glucose), insulin, lipoproteins, triglycerides (TG), high-sensitivity C-reactive protein (hs-CRP), and malondialdehyde (MDA) were determined pre- and post-intervention and compared. H. sabdariffa significantly reduced serum TG (p=0.044) and SBP (p=0.049) compared to placebo. All other variables were not significantly affected by the interventions. Daily consumption of 500 mg of H. sabdariffa L. calyx powder can decrease SBP and serum TG in MetS patients.

    The objectives of this study were to evaluate alterations of metabolites in the blood of dairy cows before, during, and after diagnosis of metritis and identify predictive serum metabolite biomarkers for metritis. DI/LC-MS/MS was used to analyze serum samples collected from both healthy and metritic cows during -8, -4, disease diagnosis, +4, and +8 wks relative to parturition. Results indicated that cows with metritis experienced altered concentrations of serum amino acids, glycerophospholipids, sphingolipids, acylcarnitines, and biogenic amines during the entire experimental period. Moreover, two sets of predictive biomarker models and one set of diagnostic biomarker models for metritis were developed, and all of them showed high sensitivity and specificity (e.g., high AUC values by the ROC curve evaluation), which indicate that serum metabolites identified have pretty accurate predictive, diagnostic, and prognostic abilities for metritis in transition dairy cows.

    Leptin is correlated with several features of metabolic syndrome; however, possible confounders (eg, obesity) of this association are not known. This study evaluated the relationship between leptin, metabolic syndrome, and insulin resistance in an Iranian population and further investigated whether this relationship is confounded by obesity or central obesity. A total of 387 participants (18-65 years old) who referred to a large university general hospital for routine health examinations were categorized into 2 groups with (n = 130) and without (n = 257) metabolic syndrome. Fasting plasma glucose, insulin, lipids, and leptin levels were measured and the homeostasis model assessment of insulin resistance (HOMA-IR) was calculated. Metabolic syndrome was defined according to the National Cholesterol Education Program Adult Treatment Panel III (NCEP ATP III) criteria. Age- and sex-adjusted leptin levels were significantly higher in patients with than those without metabolic syndrome (29.62 +/- 1.67 vs. 18.50 +/- 1.21 ng/mL, P metabolic syndrome, and its components (P insulin resistance and metabolic syndrome independent of BMI but these associations are significantly mediated through the effects of central obesity.

    Full Text Available Organic and conventional yerba mate (Ilex paraguariensis is widely used in South America to prepare nonalcoholic drinks rich in polyphenols. These compounds are able to prevent the generation of reactive species, thus minimizing the incidence of several diseases. In this perspective, we hypothesized that yerba mate may have protective effects against pentylenetetrazol (PTZ-induced oxidative damage in liver and serum of rats. Animals (n = 42 received distilled water (control or yerba mate (organic or conventional for fifteen days. Then, half of the rats of each group received 60 mg/kg PTZ intraperitoneally or saline solution. After 30 min the animals were euthanized and the liver and blood were collected. The results showed that organic and conventional yerba mate avoided PTZ-induced oxidative damage and nitric oxide production in the liver and serum of the rats. Moreover, both kinds of yerba mate prevented the decrease in enzymatic (superoxide dismutase and catalase and non-enzymatic (sulfhydryl protein content defenses in the liver and serum. In addition, histopathologic analysis of the liver showed that yerba mate reduced PTZ-induced cell damage. These findings indicate that yerba mate provides hepatoprotection and improves antioxidant status in the serum, which may contribute to the development of new therapeutic strategies using nutraceuticals drinks.

    Full Text Available OBJECTIVE: Elevated myocardial energy expenditure (MEE is related with reduced left ventricular ejection fraction, and has also been documented as an independent predictor of cardiovascular mortality. However, the serum small-molecule metabolite profiles and pathophysiological mechanisms of elevated MEE in heart failure (HF are still lacking. Herein, we used 1H-NMR-based metabolomics analysis to screen for potential biomarkers of MEE in HF. METHODS: A total of 61 subjects were enrolled, including 46 patients with heart failure and 15 age-matched controls. Venous serum samples were collected from subjects after an 8-hour fast. An INOVA 600 MHz nuclear magnetic resonance spectrometer with Carr-Purcell-Melboom-Gill (CPMG pulse sequence was employed for the metabolomics analysis and MEE was calculated using colored Doppler echocardiography. Metabolomics data were processed using orthogonal signal correction and regression analysis was performed using the partial least squares method. RESULTS: The mean MEE levels of HF patients and controls were 139.61±58.18 cal/min and 61.09±23.54 cal/min, respectively. Serum metabolomics varied with MEE changed, and 3-hydroxybutyrate, acetone and succinate were significantly elevated with the increasing MEE. Importantly, these three metabolites were independent of administration of angiotensin converting enzyme inhibitor, β-receptor blockers, diuretics and statins (P>0.05. CONCLUSIONS: These results suggested that in patients with heart failure, MEE elevation was associated with significant changes in serum metabolomics profiles, especially the concentration of 3-hydroxybutyrate, acetone and succinate. These compounds could be used as potential serum biomarkers to study myocardial energy mechanism in HF patients.

    Objective Hepcidin may be an important mediator in exercise-induced iron deficiency. Despite the studies investigating acute exercise effects on hepcidin and markers of iron metabolism, we found no studies examining the chronic effects of walking exercises (WE) on hepcidin and markers of iron metabolism in premenopausal women. The chronic effects of two 8-week different-intensity WE on hepcidin, interleukin 6 (IL-6), and markers of iron metabolism in pre-menopausal women were examined. Methods Exercise groups (EG) [moderate tempo walking group (MTWG), n = 11; brisk walking group (BWG), n = 11] walked 3 days/week, starting from 30 to 51 min. Control group (CG; n = 8) did not perform any exercises. BWG walked at ∼70%-75%; MTWG at ∼50%-55% of HRRmax. VO2max, hepcidin, IL-6, and iron metabolism markers were determined before and after the intervention. Results VO2max increased in both EGs, favoring the BWG. Hepcidin increased in the BWG (p brisk walking is advisable due to the positive changes in VO2max and some iron metabolism parameters, which may contribute to prevent iron deficiency. The increase in hepcidin levels remains unclear and necessitates further studies.

METHODS Forty SD rats were randomly divided into four groups: normal control, model, medication and TAES (10 rats/group). The PCOS model was established by giving (gavage) the animals with letrozole solution (1.0 mg/kg, once daily for 21 consecutive days). Rats of the medication group were treated with Clomiphene (1 mg/kg) once daily for 7 days, and those of the TAES group were treated with electrical stimulation (2 Hz, 3 mA) of "Guanyuan" (CV 4) and "Sanyinjiao" (SP 6) areas for 30 min, once daily for 7 consecutive days. The rats body weight and bilateral ovarian weight were detected, and the ovarian structure and follicular development degree were observed under light microscope after H. E. stain, and the serum testosterone (T), estradiol (E2), luteotrophic hormone (LH) and follicle-stimulating hormone (FSH) contents were detected using radioimmunoassay. The expression of ovarian P 450 arom (for production of estrogen)protein and P 450 c 17 α (for production of androgen) protein was detected by using immunohistochemical stain and Western blot, respectively. The body weight, bilateral ovary weight, serum T and LH contents, and ratio of LH/FSH, and ovarian P 450 c 17 α immunoactivity and protein expression levels in the model group were all significantly increased compared with the normal control group (P ovary weight, serum T and LH contents, ratio of LH/FSH, and ovarian P 450 c 17 α immunoactivity and protein expression levels, and the decreased ovarian P 450 arom immunoactivity and protein expression levels were reversed in the TAES group (P 0

    The metabolic syndrome (MetS) is one of the most important risk factors for type 2 diabetes and cardiovascular disease. This syndrome is characterized by abdominal obesity, hypertension, insulin resistance, and dyslipidemia. The plasma origin of Cholesteryl ester transfer protein (CETP) is responsible for transferring cholesterol esters from high-density lipoprotein particles to apolipoprotein B containing lipoproteins compartment. We conducted this study to investigate the association between CETP gene Taq1B (rs708272) polymorphism in the metabolic syndrome among Iranian subjects. A sample size of 200 patients diagnosed with MetS together with 200 healthy donors as control were enrolled in this study. The investigation of polymorphism was performed by the use of polymerase chain reaction and restriction fragment length polymorphism analysis. To determine the relationship between polymorphism and lipid profile, we measured lipids and CETP concentration in metabolic syndrome and control subjects. Genotype distribution and allelic frequencies of polymorphism were determined and compared in both groups. Our findings showed that all clinical and biochemical characteristics in patients differed from the control group. The results showed that genotype and allele frequency of the Taq1B polymorphism was not significantly different between two groups. Instinctively, CETP was significantly higher in metabolic syndrome (1.64 ± 0.32 µg/ml) than in control (1.53 ± 0.34 µg/ml). A low level of CETP was found in blood of B2B2 typified genotype. In spite of Taq1B polymorphism on ester transfer protein concentration, no direct correlation was found between this polymorphism and metabolic syndrome.

    Full Text Available Metabolic syndrome (MetS is defined as cluster of multiple metabolic and cardiovascular (CV abnormalities included abdominal obesity, high-normal blood pressure, dyslipidaemia, and impaired fasting glucose tolerance that exhibits has a growing prevalence worldwide. We investigated whether an elevated level of osteoprotegerin (OPG predicts imbalance between different phenotypes of circulating endothelial (EPCs and mononuclear (MPCs progenitor cells in MetS patients. We have analyzed data regarding dysmetabolic disorder subjects without known CV disease, as well as with known type two diabetes mellitus. All patients have given their informed written consent for participation in the study. This article contains data on the independent predictors of depletion in numerous of circulating EPCs and MPCs in MetS patients. The data are supplemental to our original research article describing detailed associations of elevated OPG level in MetS patients with numerous of EPCs and MPCs beyond traditional CV risk factors.

    In parallel studies with piglets of the country race the applicability of variously treated straw materials was tested in comparison with the conventional feeding of concentrate (I) after an early weaning date (30th-35th day of life) over a feeding period of 8 weeks (1st-8th week of keeping). In the rations containing 10% straw (concentrate-straw mixtures), untreated (II), HCl treated (III:HCl treatment without steaming) and partly hydrolyzed straw meal (IV:HCl treatment with subsequent steaming) were tested. In the 2nd and 8th weeks of keeping blood samples were taken from 4 animals of each group and selected parameters of the protein, fat, carbohydrate and mineral metabolism were subsequently ascertained from the blood serum. About half of the total of the 13 selected parameters showed reactions of the intermediary metabolism of the test groups caused by the feeding. With the parameters on the whole varying in the normal physiologic range, a decrease in the blood urea and creatinine concentration and an increase in the blood glucose level were detected after the use of the concentrate-straw mixtures (III and IV) in comparison with the sole feeding of concentrate (I) and partly also in comparison with untreated straw meal (II), their intensity varying in dependence on feeding and test duration. Particularly towards the end of the experiment, an increase of the activity of alkaline phosphatase was also characteristic, which was in negative correlation with the P content of the serum and in positive correlation with growth performance. The physiologic parameters are discussed in connection with the higher growth performance at reduced concentrate expenditure achieved in III and IV in comparison to I and II.

    The levels of serum aminotransferase activity, including aspartate aminotransferase (AST), in rats with acute hepatic failure at 24 h after an oral administration of CCl4 (0.01-0.5 ml/kg) were about 15-50 times higher (up to nearly 5000 IU/l) than those of vehicle control rats (about 85 IU/l). The values of total clearance (CL(tot)) of cyclosporin A, doxorubicin, tacrolimus and zonisamide in the CCl4-treated rats were decreased to about 1/2-1/3 of those in control rats. There were good correlations between AST activity and hepatic intrinsic clearance (CL(int)) (r=0.733-0.949) for the above drugs, as well as for chlorzoxazone, caffeine, lidocaine and tolbutamide after the intravenous administration of each drug in rats with acute hepatic failure. However, the slope of the linear regression equation, i.e., the ratio of decrease of CL(int) against increase of AST activity, differed markedly among these drugs. We found that there is a good correlation (r=0.953) between the values of the slope and the CL(int) of normal rats for these drugs, except for caffeine. In summary, the linear regression equation enables us to predict the decrease of CL(tot) in rats with acute hepatic failure to be predicted from the increase in serum AST activity. This approach may be useful as a guide for the dose modification of drugs for patients with acute hepatic failure.

    Bull fertility is an important target for genetic improvement, and early prediction using genetic markers is therefore a goal for livestock breeding. We performed genome-wide association studies to identify genes associated with fertility traits measured in young bulls. Data from 1118 Brahman bulls were collected for six traits: blood hormone levels of inhibin (IN) at 4 mo, luteinizing hormone (LH) following a gonadotropin-releasing hormone challenge at 4 mo, and insulin-like growth factor 1 (IGF1) at 6 mo, scrotal circumference (SC) at 12 mo, ability to produce sperm (Sperm) at 18 mo, and percentage of normal sperm (PNS) at 24 mo. All the bulls were genotyped with the BovineSNP50 chip. Sires and dams of the bull population (n = 304) were genotyped with the high-density chip (∼800 000 polymorphisms) to allow for imputation, thereby contributing detail on genome regions of interest. Polymorphism associations were discovered for all traits, except for Sperm. Chromosome 2 harbored polymorphisms associated with IN. For LH, associated polymorphisms were located in five different chromosomes. A region of chromosome 14 contained polymorphisms associated with IGF1 and SC. Regions of the X chromosome showed associations with SC and PNS. Associated polymorphisms yielded candidate genes in chromosomes 2, 14, and X. These findings will contribute to the development of genetic markers to help select cattle with improved fertility and will lead to better annotation of gene function in the context of reproductive biology.

    Background A soluble form of CD26/dipeptidyl peptidase-IV (sCD26/DPP-IV) induces DPP-IV enzymatic activity that degrades incretin. We investigated fasting serum levels of sCD26/DPP-IV and active glucagon-like peptide-1 (GLP-1) in Malaysian patients with type 2 diabetes mellitus (T2DM) with and without metabolic syndrome (MetS), as well as the associations between sCD26/DPP-IV levels, MetS, and antidiabetic therapy. Methods We assessed sCD26/DPP-IV levels, active GLP-1 levels, body mass index (BMI), glucose, insulin, A1c, glucose homeostasis indices, and lipid profiles in 549 Malaysian subjects (including 257 T2DM patients with MetS, 57 T2DM patients without MetS, 71 non-diabetics with MetS, and 164 control subjects without diabetes or metabolic syndrome). Results Fasting serum levels of sCD26/DPP-IV were significantly higher in T2DM patients with and without MetS than in normal subjects. Likewise, sCD26/DPP-IV levels were significantly higher in patients with T2DM and MetS than in non-diabetic patients with MetS. However, active GLP-1 levels were significantly lower in T2DM patients both with and without MetS than in normal subjects. In T2DM subjects, sCD26/DPP-IV levels were associated with significantly higher A1c levels, but were significantly lower in patients using monotherapy with metformin. In addition, no significant differences in sCD26/DPP-IV levels were found between diabetic subjects with and without MetS. Furthermore, sCD26/DPP-IV levels were negatively correlated with active GLP-1 levels in T2DM patients both with and without MetS. In normal subjects, sCD26/DPP-IV levels were associated with increased BMI, cholesterol, and LDL-cholesterol (LDL-c) levels. Conclusion Serum sCD26/DPP-IV levels increased in T2DM subjects with and without MetS. Active GLP-1 levels decreased in T2DM patients both with and without MetS. In addition, sCD26/DPP-IV levels were associated with Alc levels and negatively correlated with active GLP-1 levels. Moreover, metformin

    Background Obesity is a major clinical problem. The number of obese pregnant women is rising rapidly. The consequences of obesity are significant and affect every aspect of perinatal care for both the mother and the developing fetus. Adipose tissue may be responsible for chronic subclinical inflammation in obesity, being a source of inflammatory mediators. The study was designed to evaluate the analysis of the serum concentration of inflammatory mediators, including interleukin-6 (IL-6), tumor necrosis factor alpha (TNF-α), and adiponectin, in obese pregnant women at full-term pregnancies. Material/Methods The study included 40 women with body mass index (BMI) less than 30 and 24 pregnant women with BMI equal to or greater than 30, admitted to the Perinatology and Obstetrics Department of the University Hospital in Cracow in the first stage of labor. Blood samples were taken from patients to detect the serum concentration of cytokines. Ultrasound was used to evaluate the development of the fetus, including estimated fetal weight, Doppler flows, and the amount of amniotic fluid. We also included the history of chronic diseases and other complications of the pregnancy. A p-value <0.05 was considered significant. Results The level of adiponectin in obese patients as compared to controls was significantly lower. There was no statistically significant difference in either group when TNF-α and IL-6 were measured. The results of the survey are consistent with previous reports. Conclusions The exact role of inflammation in pregnancy is not well understood. Determining the exact functions of the different cytokines in physiological pregnancy and pregnancy complicated by obesity requires further study. PMID:28077838

    Full Text Available The study evaluated the profile of circulating fatty acids (FA in obese youth with and without metabolic syndrome (MetS to determine its association with nutritional status, lifestyle and metabolic variables. A cross-sectional study was conducted in 96 young people, divided into three groups: obese with MetS (OBMS, obese (OB and appropriate weight (AW. FA profiles were quantified by gas chromatography; waist circumference (WC, fat folds, lipid profile, high-sensitivity C-reactive protein, glucose, insulin, the homeostasis model assessment (HOMA index, food intake and physical activity (PA were assessed. The OBMS group had significantly greater total free fatty acids (FFAs, palmitic-16:0 in triglyceride (TG, palmitoleic-16:1n-7 in TG and phospholipid (PL; in the OB group, these FAs were higher than in the AW group. Dihomo-gamma-linolenic (DHGL-20:3n-6 was higher in the OBMS than the AW in PL and FFAs. Linoleic-18:2n-6 in TG and PL had the lowest proportion in the OBMS group. WC, PA, total FFA, linoleic-18:2n-6 in TG and DHGL-20:3n-6 in FFAs explained 62% of the HOMA value. The OB group presented some higher proportions of FA and biochemical values than the AW group. The OBMS had proportions of some FA in the TG, PL and FFA fractions that correlated with disturbances of MetS.

    Full Text Available Although it is recognized that the mechanical stresses associated with physical activity augment bone mineral density and improve bone quality, our understanding of how exercise modulates bone homeostasis at the molecular level is lacking. In a before and after trial involving 43 healthy adults, we measured the effect of six months of supervised exercise training on the spontaneous and phytohemagglutinin-induced production of osteoclastogenic cytokines (interleukin-1α, tumor necrosis factor-α, antiosteoclastogenic cytokines (transforming growth factor-β1 and interleukins 4 and 10, pleiotropic cytokines with variable effects on osteoclastogenesis (interferon-γ, interleukin-6, and T cell growth and differentiation factors (interleukins 2 and 12 by peripheral blood mononuclear cells. We also measured lymphocyte phenotypes and serum markers of bone formation (osteocalcin, bone resorption (C-terminal telopeptides of Type I collagen, and bone homeostasis (25 (OH vitamin D, estradiol, testosterone, parathyroid hormone, and insulin-like growth factor 1. A combination of aerobic, resistance, and flexibility exercises done on average of 2.5 hours a week attenuated the production of osteoclastogenic cytokines and enhanced the production of antiosteoclastogenic cytokines. These changes were accompanied by a 16% reduction in collagen degradation products and a 9.8% increase in osteocalcin levels. We conclude that long-term moderate intensity exercise exerts a favorable effect on bone resorption by changing the balance between blood mononuclear cells producing osteoclastogenic cytokines and those producing antiosteoclastogenic cytokines.

    Full Text Available The global epidemic of cardiovascular diseases leads to increased morbidity and mortality caused mainly by myocardial infarction and stroke. Atherosclerosis is the major pathological process behind this epidemic. We designed a novel model of atherosclerosis in swine. Briefly, the first group (11 pigs received normal pig feed (balanced diet group-BDG for 12 months, the second group (9 pigs was fed a Western high-calorie diet (unbalanced diet group-UDG for 12 months, the third group (8 pigs received a Western type high-calorie diet for 9 months later replaced by a normal diet for 3 months (regression group-RG. Clinical measurements included zoometric data, arterial blood pressure, heart rate and ultrasonographic evaluation of femoral arteries. Then, the animals were sacrificed and the blood serum, urine and skeletal muscle tissue were collected and 1H NMR based metabolomics studies with the application of fingerprinting PLS-DA and univariate analysis were done. Our results have shown that the molecular disturbances might overlap with other diseases such as onset of diabetes, sleep apnea and other obesity accompanied diseases. Moreover, we revealed that once initiated, molecular changes did not return to homeostatic equilibrium, at least for the duration of this experiment.

    Full Text Available Depression is an independent risk factor for cardiovascular diseases and is associated with metabolic syndrome (MetS. Levels of plasminogen activator inhibitor-1 (PAI-1, an inhibitor of tissue-type and urokinase-type plasminogen activators, are associated with MetS. To clarify the role of PAI-1 in subjects with long-term adverse mental symptomatology (LMS; including depression and MetS, we measured circulating PAI-1 levels in controls (n=111, in subjects with MetS and free of mental symptoms (n=42, and in subjects with both MetS and long-term mental symptoms (n=70. PAI-1 increased linearly across the three groups in men. In logistic regression analysis, men with PAI-1 levels above the median had a 3.4-fold increased likelihood of suffering from the comorbidity of long-term adverse mental symptoms and MetS, while no such associations were detected in women. In conclusion, our results suggest that in men high PAI-1 levels are independently associated with long-term mental symptomatology.

    Pregnancy rates (PR) to fixed-time AI (FTAI) in Brahman heifers were compared after treatment with a traditional oestradiol-based protocol (OPO-8) or a modified protocol (OPO-6) where the duration of intravaginal progesterone releasing device (IPRD) was reduced from 8 to 6 days, and the interval from IPRD removal to oestradiol benzoate (ODB) was increased from 24 to 36 h. Rising 2 yo heifers on Farm A: (n = 238 and n = 215; two consecutive days AI); B (n = 271); and C (n = 393) were allocated to OPO-8 or OPO-6. An IPRD was inserted and 1mg ODB i.m. on Day 0 for OPO-8 heifers and Day 2 for OPO-6 heifers. On Day 8, the IPRD was removed and 500 μg cloprostenol i.m. At 24h, for OPO-8 heifers, and 36 h, for OPO-6 heifers, post IPRD removal all heifers received 1mg ODB i.m. FTAI was conducted at 54 and 72 h post IPRD removal for OPO-8 and OPO-6 heifers. At Farm A, OPO-6 heifers, AI on the second day, the PR was 52.4% to FTAI (P = 0.024) compared to 36.8% for OPO-8 heifers. However, no differences were found between OPO-8 and OPO-6 protocols at Farm A (first day of AI) (39.9 vs. 35.7%), or Farms B (26.2 vs. 35.4%) and C (43.2% vs. 40.3%). Presence of a corpus luteum at IPRD insertion affected PR to FTAI (43.9% vs. 28.8%; P OPO-6 may be a viable alternative to the OPO-8 protocol for FTAI in B. indicus heifers.

    We investigated the association between cystatin C and carotid intima-media thickness (CIMT) in patients with metabolic syndrome (MetS) and normal estimated glomerular filtration rate (eGFR). We identified 4895 participants (1112 with MetS vs. 3783 without MetS) with normal eGFR and without prior cardiovascular diseases. The MetS patients were stratified into 4 subgroups (Q1-Q4) by cystatin C quartiles. MetS patients showed higher cystatin C and CIMT than controls (P<0.001). Among MetS patients, those in higher cystatin C quartiles were more likely to present with increased age, systolic blood pressure, fasting plasma glucose, and CIMT (P<0.01), accompanied with decreased eGFR (P<0.001). After adjusting for age, gender, eGFR, and all components of MetS, cystatin C quartiles were significantly related to the odds ratios. Compared to subgroup Q1, the odds ratios for elevated CIMT were 1.883 (1.259-2.819), 2.194 (1.468-3.279), and 4.164 (2.669-6.497) moving from Q2 to Q4. By ROC analysis, the optimal cystatin C cut-off point was 0.86mg/l for detecting elevated CIMT (sensitivity 60.7%, specificity 69.2%). Based on a positive and graded association between cystatin C and CIMT, we assessed that early detection of subclinical atherosclerosis might be necessary in patients with MetS even if at the normal eGFR stage.

    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.

    The purpose of this study was to examine the associations between serum uric acid (SUA) levels and the incidences of hypertension and metabolic syndrome (MetS) in a large screened cohort of Japanese men and women. We evaluated 4812 subjects (males, 2528; females, 2284; mean age, 47.5 years) who underwent health checkups between 2006 and 2010 and were free of hypertension and MetS in 2006. After 4 years, 618 (13%), 764 (16%) and 158 (3%) subjects developed hypertension, MetS and hypertension with MetS, respectively. Increased SUA levels were significantly and positively associated with the incidences of hypertension, MetS and hypertension with MetS. Compared with the first quartile of SUA levels, the odds ratios (95% confidence intervals) for the third and fourth quartiles, respectively, were as follows: 1.5 (1.1-2.1; P = 0.0128) and 1.8 (1.2-2.5; P = 0.0022) for hypertension, 1.3 (0.9-1.9; P = 0.1910) and 1.8 (1.2-2.7; P = 0.0039) for MetS and 2.7 (1.1-6.6; P = 0.0276) and 3.2 (1.3-8.0; P = 0.0115) for hypertension with MetS. In conclusion, increased SUA levels were significantly and independently associated with the incidences of hypertension and MetS in subjects without hypertension or MetS at baseline. Increased SUA levels might also be correlated with the incidence of hypertension with MetS.

  16. Serum Metabolic Alterations upon Zika Infection

    2017-10-01

    Full Text Available Zika virus (ZIKV infection has recently emerged as a major concern worldwide due to its strong association with nervous system malformation (microcephaly of fetuses in pregnant women infected by the virus. Signs and symptoms of ZIKV infection are often mistaken with other common viral infections. Since transmission may occur through biological fluids exchange and coitus, in addition to mosquito bite, this condition is an important infectious disease. Thus, understanding the mechanism of viral infection has become an important research focus, as well as providing potential targets for assertive clinical diagnosis and quality screening for hemoderivatives. Within this context, the present work analyzed blood plasma from 79 subjects, divided as a control group and a ZIKV-infected group. Samples underwent direct-infusion mass spectrometry and statistical analysis, where eight markers related to the pathophysiological process of ZIKV infection were elected and characterized. Among these, Angiotensin (1-7 and Angiotensin I were upregulated under infection, showing an attempt to induce autophagy of the infected cells. However, this finding is concerning about hypertensive individuals under treatment with inhibitors of the Renin-Angiotensin System (RAS, which could reduce this response against the virus and exacerbate the symptoms of the infection. Moreover, one of the most abundant glycosphingolipids in the nervous tissue, Ganglioside GM2, was also elected in the present study as an infection biomarker. Considered an important pathogen receptor at membrane's outer layer, this finding represents the importance of gangliosides for ZIKV infection and its association with brain tropism. Furthermore, a series of phosphatidylinositols were also identified as biomarkers, implying a significant role of the PI3K-AKT-mTOR Pathway in this mechanism. Finally, these pathways may also be understood as potential targets to be considered in pharmacological intervention studies on ZIKV infection management.

    To assess the effects of long-term multifactorial intervention on renal function and serum uric acid (SUA) levels and their association with estimated cardiovascular disease (eCVD) risk and actual CVD events. This prospective, randomized, target-driven study included 1123 subjects (45.6% men, age 45-65 years) with metabolic syndrome (MetS) but without diabetes or CVD. Patients were randomized to multifactorial treatment. Atorvastatin was titrated from 10-80 mg/day aiming at a low density lipoprotein cholesterol (LDL-C) target of <100 mg/dl (group A) or an LDL-C target of <130 mg/dl (group B). Changes in estimated glomerular filtration rate (eGFR) and SUA levels were recorded in all patients and in the subgroup with stage 3 chronic kidney disease (CKD; eGFR = 30-59 ml/min/1.73 m(2); n = 349). We used ANOVA to compare changes within the same group, unpaired Student t-test to compare results between groups at specific time points, and log-rank test to compare event free survival. The eCVD-risk reduction was greater in group A. In the overall study population, eGFR increased by 3.5% (p < 0.001) and SUA levels fell by 5.6% (p < 0.001). In patients from group A with stage 3 CKD (group A1; n = 172), eGFR increased by 11.1% (p < 0.001) from baseline and by 7.5% (p < 0.001) in group B1 (n = 177; p < 0.001 vs. the change in group A1). The corresponding fall in SUA levels was 10.7% in group A1 (p < 0.001 vs. baseline) and 8.3% in group B1 (p < 0.001 vs. baseline and group A1). These changes were mainly attributed to atorvastatin treatment. Among the CKD stage 3 patients there were no CVD events in group A1, while 6 events occurred in group B1 (p = 0.014). Multifactorial intervention in patients with MetS without established CVD improved renal function and reduced SUA levels. These changes were more prominent in stage 3 CKD patients and might have contributed to the reduction in eCVD risk and clinical events. Original

    The objective of this study was to define the physiologic needs of domestic cat embryos to facilitate development of a feline-specific culture medium. In a series of factorial experiments, in vivo-matured oocytes (n = 2040) from gonadotropin-treated domestic cats were inseminated in vitro to generate embryos (n = 1464) for culture. In the initial study, concentrations of NaCl (100.0 vs. 120.0 mM), KCl (4.0 vs. 8.0 mM), KH(2)PO(4) (0.25 vs. 1.0 mM), and the ratio of CaCl(2) to MgSO(4)-7H(2)O (1.0:2.0 mM vs. 2.0:1.0 mM) in the medium were evaluated during Days 1-6 (Day 0: oocyte recovery and in vitro fertilization [IVF]) of culture. Subsequent experiments assessed the effects of varying concentrations of carbohydrate (glucose, 1.5, 3.0, or 6.0 mM; l-lactate, 3.0, 6.0, or 12.0 mM; and pyruvate, 0.1 or 1.0 mM) and essential amino acids (EAAs; 0, 0.5, or 1.0x) in the medium during Days 1-3 and Days 3-6 of culture. Inclusion of vitamins (0 vs. 1.0x) and fetal calf serum (FCS; 0 vs. 5% [v/v]) in the medium also was evaluated during Days 3-6. Development and metabolism of IVF embryos on Day 3 or Day 6 were compared to age-matched in vivo embryos recovered from naturally mated queens. A feline-optimized culture medium (FOCM) was formulated based on these results (100.0 mM NaCl, 8.0 mM KCl, 1.0 mM KH(2)PO(4), 2.0 mM CaCl(2), 1.0 mM MgSO(4), 1.5 mM glucose, 6.0 mM L-lactate, 0.1 mM pyruvate, and 0x EAAs with 25.0 mM NaHCO(3), 1.0 mM alanyl-glutamine, 0.1 mM taurine, and 1.0x nonessential amino acids) with 0.4% (w/v) BSA from Days 0-3 and 5% FCS from Days 3-6. Using this medium, ~70% of cleaved embryos developed into blastocysts with profiles of carbohydrate metabolism similar to in vivo embryos. Our results suggest that feline embryos have stage-specific responses to carbohydrates and are sensitive to EAAs but are still reliant on one or more unidentified components of FCS for optimal blastocyst development.

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

    Thyroid hormones influence all major metabolic pathways. Their most obvious and well-known action is an increase in basal energy expenditure obtained acting on protein, carbohydrate and lipid metabolism. With specific regard to lipid metabolism, thyroid hormones affect synthesis, mobilization and degradation of lipids, although degradation is influenced more than synthesis. The main and best-known effects on lipid metabolism include: (a) enhanced utilization of lipid substrates; (b) increase in the synthesis and mobilization of triglycerides stored in adipose tissue; (c) increase in the concentration of non-esterified fatty acids (NEFA); and (d) increase of lipoprotein-lipase activity. While severe hypothyroidism is usually associated with an increased serum concentration of total cholesterol and atherogenic lipoproteins, the occurrence of acute myocardial infarction (AMI) in hypothyroid patients is not frequent. However, hypothyroid patients appear to have an increased incidence of residual myocardial ischemia following AMI. Even in subclinical hypothyroidism, which is characterized by raised serum TSH levels with normal serum thyroid hormone concentrations, mild hyperlipidemia is present and may contribute to an increased risk of atherogenesis. Prudent substitution therapy with L-thyroxine is indicated in patients with both overt and subclinical hypothyroidism, with or without angina, to counteract the cardiovascular risk resulting from hyper-dyslipidemia.

    Full Text Available BACKGROUND: Associations of serum calcium levels with the metabolic syndrome and other novel cardio-metabolic risk factors not classically included in the metabolic syndrome, such as those involved in oxidative stress, are largely unexplored. We analyzed the association of albumin-corrected serum calcium levels with conventional and non-conventional cardio-metabolic risk factors in a general adult population. METHODOLOGY/PRINCIPAL FINDINGS: The CoLaus study is a population-based study including Caucasians from Lausanne, Switzerland. The metabolic syndrome was defined using the Adult Treatment Panel III criteria. Non-conventional cardio-metabolic risk factors considered included: fat mass, leptin, LDL particle size, apolipoprotein B, fasting insulin, adiponectin, ultrasensitive CRP, serum uric acid, homocysteine, and gamma-glutamyltransferase. We used adjusted standardized multivariable regression to compare the association of each cardio-metabolic risk factor with albumin-corrected serum calcium. We assessed associations of albumin-corrected serum calcium with the cumulative number of non-conventional cardio-metabolic risk factors. We analyzed 4,231 subjects aged 35 to 75 years. Corrected serum calcium increased with both the number of the metabolic syndrome components and the number of non-conventional cardio-metabolic risk factors, independently of the metabolic syndrome and BMI. Among conventional and non-conventional cardio-metabolic risk factors, the strongest positive associations were found for factors related to oxidative stress (uric acid, homocysteine and gamma-glutamyltransferase. Adiponectin had the strongest negative association with corrected serum calcium. CONCLUSIONS/SIGNIFICANCE: Serum calcium was associated with the metabolic syndrome and with non-conventional cardio-metabolic risk factors independently of the metabolic syndrome. Associations with uric acid, homocysteine and gamma-glutamyltransferase were the strongest. These

    Metabolically healthy obese is the designation for a subgroup of obese individuals with normal metabolic features. However, metabolically healthy obese individuals are prone to developing metabolic syndrome. Serum triiodothyronine (T3) levels are associated with various metabolic risk factors including obesity. Therefore, this longitudinal study aimed to explore the possible correlation between serum T3 concentration and the onset of MetS in metabolically healthy obese persons. A retrospective analysis of 992 euthyroid metabolically healthy obese subjects who underwent yearly health checkups over 6 years was performed. The risk of developing MetS was analyzed according to baseline T3 concentration, as both tertiles and continuous values, using Cox regression analysis. Serum T3 concentration at the end of the study was further analyzed according to the final metabolic phenotype. The incidence of MetS was 464 cases (46.8%) during a median 3.3 years of follow-up (3168.2 person-years). The hazard ratio for incident MetS enhanced with increasing T3 concentration in both the crude and adjusted models. Higher baseline serum T3 levels were associated with unfavorable metabolic parameters. However, over the course of the study, serum T3 concentration significantly increased in subjects who sustained metabolically healthy phenotypes compared to baseline value, while it significantly decreased in the subjects who developed MetS. Serum T3 concentrations exhibit distinct associations with development of metabolic syndrome in euthyroid metabolically healthy obese persons, but its increment during follow-up maintained metabolically healthy state. These findings suggest that serum T3 modulation might be an adaptive process to protect against metabolic deterioration.

    Three groups of male rats were housed in metabolic cages. The control group was fed ad libitum, a second group was fasted and diabetes was induced in the third group by the subcutaneous injection of alloxan. After 48 hours all animals were bled and livers, which were quick-frozen in situ, were obtained. Fasted and diabetic animals were ketotic as manifested by lowering urinary pH and elevated urinary and blood acetoacetate and ..beta..-hydroxybutyrate. Blood and hepatic content of acetate was elevated in diabetic versus control rats. Blood and hepatic content of acetate was not increased in fasted animals. In fasted rats total urinary Zn and Cu were decreased and Mg and Ca did not differ significantly from control values. In diabetic rats total urinary excretion of Mg was increased whereas urinary Zn, Cu and Ca levels did not differ significantly from control values. In fasted animals only serum Zn was diminished. In diabetic rats serum Cu and Ca were decreased and serum Mg was increased while serum Zn was unchanged. Thus, the ketosis of fasting differs from the ketosis of diabetes in several of its metabolic manifestations. 11 references, 9 figures.

    2012-09-01

    Blood glucose determination is one of the most common clinical diagnostic tests. Often, blood is collected in a field station and analysis is carried out in a remote laboratory. Because blood cells can continue to metabolize glucose, the time of determination of blood glucose after drawing the blood is important. In order to test the relative suitability of plasma and serum for blood glucose determination, fluoride plasma and Ethylene Diamine Tetra Acetic acid (EDTA) plasma were compared with the serum of the same patient. The analyses were carried out within 10 min of drawing the blood and, thereafter, with a gap of 4 hr and 8 hr. Serum gave values lower than fluoride plasma by 1.15%. Although this difference was statistically significant, it may not be physiologically relevant. Hence, serum may be used for blood glucose determination with an error of 1.15%. On storing the sample at room temperature for 8 hr, the serum glucose value decreased by 8%. Even fluoride plasma had 4.3% lower glucose. Hence, blood glucose should be determined within as short a time as possible after drawing the blood. © 2012 Wiley Periodicals, Inc.

    Full Text Available Abstract Background The applications of proteomic strategies to ovine medicine remain limited. The definition of serum proteome may be a good tool to identify useful protein biomarkers for recognising sub-clinical conditions and overt disease in sheep. Findings from bovine species are often directly translated for use in ovine medicine. In order to characterize normal protein patterns and improve knowledge of molecular species-specific characteristics, we generated a two-dimensional reference map of sheep serum. The possible application of this approach was tested by analysing serum protein patterns in ewes with mild broncho-pulmonary disease, which is very common in sheep and in the peripartum period which is a stressful time, with a high incidence of infectious and parasitic diseases. Results This study generated the first reference 2-DE maps of sheep serum. Overall, 250 protein spots were analyzed, and 138 identified. Compared with healthy sheep, serum protein profiles of animals with rhino-tracheo-bronchitis showed a significant decrease in protein spots identified as transthyretin, apolipoprotein A1 and a significant increase in spots identified as haptoglobin, endopin 1b and alpha1B glycoprotein. In the peripartum period, haptoglobin, alpha-1-acid glycoprotein, apolipoprotein A1 levels rose, while transthyretin content dropped. Conclusions This study describes applications of proteomics in putative biomarker discovery for early diagnosis as well as for monitoring the physiological and metabolic situations critical for ovine welfare.

    2011-08-01

    Serum starvation is one of the most frequently performed procedures in molecular biology and there are literally thousands of research papers reporting its use. In fact, this method has become so ingrained in certain areas of research that reports often simply state that cells were serum starved without providing any factual details as to how the procedure was carried out. Even so, we quite obviously lack unequivocal terminology, standard protocols, and perhaps most surprisingly, a common conceptual basis when performing serum starvation. Such inconsistencies not only hinder interstudy comparability but can lead to opposing and inconsistent experimental results. Although it is frequently assumed that serum starvation reduces basal activity of cells, available experimental data do not entirely support this notion. To address this important issue, we studied primary human myotubes, rat L6 myotubes and human embryonic kidney (HEK)293 cells under different serum starvation conditions and followed time-dependent changes in important signaling pathways such as the extracellular signal-regulated kinase 1/2, the AMP-activated protein kinase, and the mammalian target of rapamycin. Serum starvation induced a swift and dynamic response, which displayed obvious qualitative and quantitative differences across different cell types and experimental conditions despite certain unifying features. There was no uniform reduction in basal signaling activity. Serum starvation clearly represents a major event that triggers a plethora of divergent responses and has therefore great potential to interfere with the experimental results and affect subsequent conclusions.

    We previously reported that dietary intake of shiitake mushroom (SM; Lentinus edodes) decreased serum concentrations of polar lipids in male rats. This study evaluated the dietary effects of SM on serum cholesterol-related and serum antioxidant indexes in rats of both sexes. Sprague-Dawley rats [38 dams and their offspring (20 males and 20 females/diet)] were fed diets containing 0 (control), 1%, 4%, or 10% (wt:wt) SM powder from gestation day 4 through to postnatal day (PND) 126. Biochemical indexes were monitored during the midgrowth phase (PNDs 50-66). The food consumption by offspring fed the control diet and diets supplemented with SM was not different when measured on PND 65. However, the 4% and 10% SM diets resulted in male rats with 7% lower body weights than those of the other 2 groups on PND 66. SM consumption dose-dependently decreased the concentrations of lipidemia-related factors in sera, irrespective of sex. At PND 50, serum concentrations of total cholesterol, HDL cholesterol, and non-HDL cholesterol in SM-fed male and female rats were generally lower (3-27%) than those in the corresponding control groups. Consumption of the 10% SM diet resulted in significantly decreased (55%) serum triglyceride concentrations relative to the control groups for both sexes. The 10% SM diet elicited a 62% reduction of serum leptin concentrations in females but not in males, and this same diet increased serum insulin (137%) and decreased serum glucose (15%) in males compared with controls. Serum lipophilic antioxidant capacity in males and females fed SM diets was generally lower (31-86%) than that in the control groups. SM decreased the concentrations of lipidemia-related factors in rat sera irrespective of sex. The SM-elicited reduction of lipophilic antioxidant capacity irrespective of sex may reflect a lower pro-oxidative state and, hence, improved metabolic profile. © 2016 American Society for Nutrition.

    Full Text Available Objectives. Resistin is a member of cysteine-rich molecules. Several studies have been carried out to determine the biological effect of resistin, nevertheless a significant number are animal studies. All the studies performed regarding the relationship between serum resistin and obesity were merely accomplished in women. To the best of our knowledge, there is no survey on the correlation of the serum resistin level and obesity in male children. The aim of the present study is to assess serum concentration of resistin in obese male children. Methods. Between June 2009 and January 2010, we enrolled 42 randomly selected obese male students (body mass index (BMI >95th percentile, age 15.7±1.5. Thirty-eight healthy age-matched male students with normal BMI (<85th percentile were selected as a control group for the purpose of comparison of the serum resistin levels. Results. Serum resistin levels were measured in obese and control group. No significant difference was found between resistin levels of the 2 groups (obese: 9.21±5.6 ng/mL versus normal: 9.83±4.3 ng/mL; =.582. There was no significant correlation between serum resistin level and BMI. Assessing the resistin level in male subjects was the distinct feature of our study. The outstanding finding of this research is that there is no correlation between serum resistin level and obesity. Conclusion. We have demonstrated that there is no correlation between obesity in male children and resistin level. Consequently, metabolic abnormalities of insulin resistance seen in obese male patients are not related to resistin.

    Drug-resistant extraintestinal pathogenic Escherichia coli (ExPEC) strains are the major cause of colisepticemia (colibacillosis), a condition that has become an increasing public health problem in recent years. ExPEC strains are characterized by high resistance to serum, which is otherwise highly toxic to most bacteria. To understand how these bacteria survive and grow in serum, we performed system-wide analyses of their response to serum, making a clear distinction between the responses to nutritional immunity and innate immunity. Thus, mild heat inactivation of serum destroys the immune complement and abolishes the bactericidal effect of serum (inactive serum), making it possible to examine nutritional immunity. We used a combination of deep RNA sequencing and proteomics in order to characterize ExPEC genes whose expression is affected by the nutritional stress of serum and by the immune complement. The major change in gene expression induced by serum-active and inactive-involved metabolic genes. In particular, the serum metabolic response is coordinated by three transcriptional regulators, Fur, BasR, and CysB. Fur alone was responsible for more than 80% of the serum-induced transcriptional response. Consistent with its role as a major serum response regulator, deletion of Fur renders the bacteria completely serum sensitive. These results highlight the role of metabolic adaptation in colisepticemia and virulence. Drug-resistant extraintestinal pathogenic Escherichia coli (ExPEC) strains have emerged as major pathogens, especially in community- and hospital-acquired infections. These bacteria cause a large spectrum of syndromes, the most serious of which is septicemia, a condition with a high mortality rate. These bacterial strains are characterized by high resistance to serum, otherwise highly toxic to most bacteria. To understand the basis of this resistance, we carried out system-wide analyses of the response of ExPEC strains to serum by using proteomics and

    Experimental and observational studies suggest a role for uric acid in non-alcoholic fatty liver disease (NAFLD). We examined the association between serum uric acid levels and NAFLD in a large population-based study from the United States. A cross-sectional analysis of 10,732 nondiabetic adults who participated in the National Health and Nutrition Examination Survey 1988-1994. Sex specific uric acid quartiles were defined: ≤5.2, 5.3-6.0, 6.1-6.9, and >6.9mg/dL for men and ≤3.7, 3.8-4.5, 4.6-5.3, and >5.3mg/dL for women. NAFLD presence and severity were defined by ultrasonographic detection of steatosis in the absence of other liver diseases. We modeled the probability that more severe NAFLD would be associated with the highest quartiles of uric acid. Compared to the 1st quartile, the odds ratio for NAFLD was 1.79 (95% C.I. 1.49-2.15, puric acid (4th quartile) was significantly associated with NAFLD (odds ratio 1.43; 95% C.I. 1.16-1.76, puric acid is associated with greater severity of NAFLD. Elevated uric acid level is independently associated with ultrasound-diagnosed NAFLD in a nationally representative sample of United States nondiabetic adults. Increasing uric acid is associated with increasing severity of NAFLD on ultrasonography. These findings warrant further studies on the role of uric acid in NAFLD. Published by Elsevier Inc.

    The aim of the present study was to investigate the possible effects of the +83C/T polymorphism in apolipoprotein AI gene (apoA1) on the changes of serum lipids, glucose, insulin and the homeostasis model assessment of insulin resistance (HOMA-IR) induced by a high-carbohydrate diet in healthy youth. Fifty-six participants were given a washout diet for 7 d, followed by a high-carbohydrate diet for 6 d. The washout diet contained 15% protein, 31% fat and 54% carbohydrate. The high-carbohydrate diet contained 15% protein, 15% fat and 70% carbohydrate. Twelve hour fasting venous blood was drawn on the mornings of the first, eighth and fourteenth days. Blood lipids, glucose and insulin were measured, and HOMA-IR was calculated. The genome DNA was extracted and the apoA1 + 83C/T polymorphism was determined by polymerase chain reaction-based restriction fragment length polymorphism. Triglyceride and insulin were found significantly increased in the subjects with the CC genotype, but not in the T carriers after the high-carbohydrate diet. Significant decreases of total cholesterol and LDL-C and a significant increase of HDL-C were observed after the dietary intervention of the high-carbohydrate diet. The triglyceride and insulin changes after the high-carbohydrate diet can be modulated by the apoA1 +83C/T polymorphism, and the T allele may eliminate the increase in triglyceride and insulin induced by the high-carbohydrate diet.

    31 patients admitted to hospital with different non-thyroidal intercurrent diseases were found to have raised total serum-thyroxine (T4) and free T4 together with normal serum-triiodothyronine (T3) concentrations. At admission none was clinically hyperthyroid. Patients were assigned to 3 groups according to clinical course and the laboratory findings. In the first group (14 patients) classic hyperthyroidism developed after recovery from the intercurrent disease. 11 out of these 14 patients had recently received iodine-containing preparations. In a second group (11 patients) the initially raised serum-T4 rapidly returned to normal with recovery from the non-thyroidal disease. In a third group (6 patients) serum-T4 concentrations remained raised well after recovery from intercurrent disease. In this group, there were 2 cases of transient iodine-induced (Jod-Basedow) hyperthyroidism in which raised serum-T4 returned spontaneously to normal after several months as iodine was eliminated. These results indicate that increase in serum-T4 with normal serum-T3 in patients with intercurrent systemic disease is not always the result of hyperthyroidism and in many cases probably reflects changes in peripheral metabolism of T4. It is suggested that careful clinical follow-up is needed in patients with raised serum-T4 and normal serum-T3 for the early detection and treatment of classic hyperthyroidism.

    This study sought to compare iodine-124 positron emission tomography/computed tomography ({sup 124}I-PET/CT) and 2-[{sup 18}F]fluoro-2-deoxy-d-glucose- (FDG-) PET in the detection of recurrent differentiated thyroid carcinoma (DTC) lesions in patients with increasing serum thyroglobulin (Tg), Tg-antibodies, or both, but without pathological cervical ultrasonography. We assessed the lesion detection accuracy of {sup 124}I-PET alone, CT alone, {sup 124}I-PET/CT, FDG-PET, and all these modalities combined. The study included 21 patients (9 follicular, 12 papillary DTC) who had been rendered disease-free by thyroidectomy and radioiodine treatment (RIT) and followed up for 21-275 months after the last RIT. In all patients, FDG-PET was performed first. Within 1 week, {sup 124}I-PET/CT was performed 24 h after oral administration of 43 {+-} 11 MBq {sup 124}I. Imaging results were correlated with further clinical follow-up with (n = 12) or without (n = 9) post-study histology as the reference standard. The sensitivities for DTC lesion detection were: {sup 124}I-PET, 49%; CT, 67%; {sup 124}I-PET/CT, 80%; FDG-PET, 70%; and all modalities combined, 91%. For local recurrences (distant metastases), the sensitivities were: {sup 124}I-PET, 60% (45%); CT, 20% (84%); and FDG-PET, 65% (71%). One-third of lesions demonstrated pathological tracer uptake with both {sup 124}I- and FDG-PET, while two-thirds were positive with only one of these modalities. Used together, {sup 124}I-PET and CT allow localization of foci of highly specific {sup 124}I uptake as well as non-iodine-avid lesions. The combination of {sup 124}I-PET/CT and FDG-PET improves restaging in recurrent DTC by enabling detection on whole-body scans of local recurrence or metastases that are often not found if only one of the methods or other imaging modalities are applied.

    Alkaline phosphatase is typically considered as an innocent by-stander, but emerging data suggest that alkaline phosphatase might play a pathogenic role in vascular calcification and thus contribute to increased mortality in hemodialysis patients. Longitudinal analyses of the existing HEMO Study database. 1,827 HEMO Study participants. Serum alkaline phosphatase level. OUTCOME AND MEASUREMENTS: All-cause and cardiovascular mortality. Based on the median serum alkaline phosphatase of 97 IU/l, participants were divided into low ( or = 97 IU/l) serum alkaline phosphatase groups. The lower serum alkaline phosphatase group was associated with older age, male gender, non-black race and shorter dialysis years as well as higher serum calcium, higher serum calcium-phosphorus product and lower parathyroid hormone levels. Mean serum liver enzyme values were in the normal range in both groups, but the high alkaline phosphatase group had slightly higher values. In a multivariate time-dependent Cox model using baseline and follow-up values of serum alkaline phosphatase levels, adjusted for demographics, HEMO Study groups, comorbidity, bone metabolism parameters and liver enzymes, each doubling of serum alkaline phosphatase was significantly associated with increased hazard of all-cause (hazard ratio 1.44, 95% CI 1.30 - 1.59) and cardiovascular mortality (hazard ratio 1.35, 95% CI 1.16 - 1.57). Nonstandardized measurements of alkaline phosphatase. Serum alkaline phosphatase is associated with increased mortality in hemodialysis patients, independent of bone metabolism parameters and liver enzymes. Alkaline phosphatase might be a potential therapeutic target in hemodialysis patients.

    Calcium is essential for many metabolic process, including nerve function, muscle contraction, and blood clotting. The metabolic pathways that contribute to maintain serum calcium levels are bone remodeling processes, intestinal absorption and secretion, and renal handling, but hypercalcemia occurs when at least 2 of these 3 metabolic pathways are altered. Calcium metabolism mainly depends on the activity of parathyroid hormone (PTH). Its secretion is strictly controlled by the ionized serum calcium levels through a negative feed-back, which is achieved by the activation of calcium-sensing receptors (CaSRs) mainly expressed on the surface of the parathyroid cells. The PTH receptor in bone and kidney is now referred as PTHR1. The balance of PTH, calcitonin, and vitamin D has long been considered the main regulator of calcium metabolism, but the function of other actors, such as fibroblast growth factor-23 (FGF-23), Klotho, and TPRV5 should be considered. Primary hyperparathyroidism and malignancy are the most common causes of hypercalcemia, accounting for more than 90% of cases. Uncontrolled hypercalcemia may cause renal impairment, both temporary (alteration of renal tubular function) and progressive (relapsing nephrolithiasis), leading to a progressive loss of renal function, as well as severe bone diseases, and heart damages. Advances in the understanding of all actors of calcium homeostasis will be crucial, having several practical consequences in the treatment and prevention of hypercalcemia. This would allow to move from a support therapy, sometimes ineffective, to a specific and addressed therapy, especially in patients with chronic hypercalcemic conditions unsuitable for surgery.

    Full Text Available Male infertility is considered a common health problem, and non-obstructive azoospermia with unclear pathogenesis is one of the most challenging tasks for clinicians. The objective of this study was to investigate the differential serum metabolic pattern in non-obstructive azoospermic men and to determine potential biomarkers related to spermatogenic dysfunction. Serum samples from patients with non-obstructive azoospermia (n = 22 and healthy controls (n = 31 were examined using high-performance liquid chromatography-tandem mass spectrometry (HPLC-MS/MS. Serum metabolomic profiling could differentiate non-obstructive azoospermic patients from healthy control subjects. A total of 24 metabolites were screened and identified as potential markers, many of which are involved in energy production, oxidative stress and cell apoptosis in spermatogenesis. Moreover, the results showed that various metabolic pathways, including d-glutamine and d-glutamate metabolism, taurine and hypotaurine metabolism, pyruvate metabolism, the citrate cycle and alanine, aspartate and glutamate metabolism, were disrupted in patients with non-obstructive azoospermia. Our results indicated that the serum metabolic disorders may contribute to the etiology of non-obstructive azoospermia. This study suggested that serum metabolomics could identify unique metabolic patterns of non-obstructive azoospermia and provide novel insights into the pathogenesis underlying male infertility.

    Full Text Available Aim: Metabolic syndrome has gained increased attention in the last century after researchers identified its important role in cardiovascular mortality and morbidity in developed countries. Despite limited research into the relationship between metabolic syndrome and prostate cancer (PCa, the precise relationship has not been elucidated due to lack of research into the specific factors associated with PCa. To fill this research gap, we evaluated the incidence of PCa in patients with metabolic syndrome and the relationship between metabolic syndrome and the parameters of PCa. Material and Method: We retrospectively evaluated the biochemical analyses of the serum parameters and pathological reports of 102 PCa patients diagnosed by transrectal ultrasound. After determining the incidence of metabolic syndrome in patients with PCa, we divided the patients into two groups, those with and without a diagnosis of metabolic syndrome. We then compared the serum PSA level, age, total prostate volume, Gleason score, triglyceride (TG level, high-density lipoprotein cholesterol level (HDL-C, blood pressure, and fasting glucose level of the two groups. Results: We included 102 patients with a diagnosis of prostate cancer in the present study. Among the 102 patients, 18 (17.6% were diagnosed with metabolic syndrome. While the PSA levels of the PCa patients were found to be significantly lower in those with metabolic syndrome compared to those without metabolic syndrome (P=0.04, no difference was found between the groups regarding the other components of PCa (P>0.05. Discussion: Serum PSA level was found to be significantly lower in those with metabolic syndrome. This result leads us to consider whether prostate biopsy should be performed in patients with metabolic syndrome who have lower PSA levels than the levels currently specified for biopsy. Further research into the parameters of PCa needs to be conducted to confirm our findings.

    It is very important to monitor levels of serum iron and other factors of iron metabolism and oxygen transport system as they play a very important role in functional ability of football players. A decrease in serum iron level can be the very first sign of development of iron deficiency anaemia, which seriously influences health and functional ability of an athlete and is a common problem in competitive sports. The aim of this study was to observe and evaluate changes in serum iron values during the competition season in relation to the training process. During four years, serum iron level was measured in 28-34 players of one of the top football clubs in Serbia, four times a year: at the beginning and at peak-point of both half-seasons. Differences between basic and control findings, relative and absolute changes in serum iron levels and statistical significance of the findings were than calculated. There was a significant decrease in mean serum iron levels on each control test, compared to basic values. Mean value of control serum iron levels is significantly lower than mean of preseason values (20.64 +/- 6.58 vs. 16.38 +/- 5.51 micromol/l). A significant decrease in serum iron level among footballers during both half-seasons is most probably due to an increased loss and/or diminished absorption resulting from a high intensity training process. Because the decline in serum iron may be an early sign of iron store depletion and iron deficiency anaemia, it is very important to evaluate it regularly, along with other factors of iron metabolism and oxygen transport system.

    Clinical data have suggested that obesity protects against osteoporosis. Leptin, mainly secreted by white adipose tissue, might be involved by mediating an effect on bone metabolism. This study was conducted to investigate a possible relationship of leptin and bone turn-over in postmenopausal women with osteoporosis. We measured bone mineral density (BMD), serum leptin levels and markers of bone metabolism, including osteocalcin and cross-laps in 44 patients with osteoporosis. The main group consisted of 32 postmenopausal women. Mean serum leptin was 13.1 microg/L and showed no statistically significant difference to the levels measured in a collective of normal persons adjusted for age and BMI. When related to serum cross-laps as markers of bone resorption, a positive correlation (posteoporosis.

    Although metabolic alkalosis is a common occurrence, no study has evaluated its prevalence, associated factors or outcomes in critically ill patients. This is a retrospective study from the Multiparameter Intelligent Monitoring in Intensive Care II database. From 23,529 adult patient records, 18,982 patients met the inclusion criteria. Serum bicarbonate levels demonstrated a U-shaped association with mortality with knots at 25 and 30 mEq/l. Of the total included patients, 5,565 (29.3 %) had at least one serum bicarbonate level measurement >30 mEq/l. The majority were exposed to multiple factors that are classically associated with metabolic alkalosis (mainly diuretic use, hypernatremia, hypokalemia and high gastric output). Patients with increased serum bicarbonate exhibited increased ICU LOS, more days on mechanical ventilation and higher hospital mortality. After multivariate adjustment, each 5-mEq/l increment in the serum bicarbonate level above 30 mEq/l was associated with an odds ratio of 1.21 for hospital mortality. The association between increased serum bicarbonate levels and mortality occurs independently of its possible etiologies. An increased serum bicarbonate level is common in critically ill patients; this can be attributed to multiple factors in the majority of cases, and its presence and duration negatively influence patient outcomes.

    Metabolic acidosis is frequently observed in clinical practice, especially among critically ill patients and/or in the course of renal failure. Complex mechanisms are involved, in most cases identifiable by medical history, pathophysiology-based diagnostic reasoning and measure of some key acid-base parameters that are easily available or calculable. On this basis the bedside differential diagnosis of metabolic acidosis should be started from the identification of the two main subtypes of metabolic acidosis: the high anion gap metabolic acidosis and the normal anion gap (or hyperchloremic) metabolic acidosis. Metabolic acidosis, especially in its acute forms with elevated anion gap such as is the case of lactic acidosis, diabetic and acute intoxications, may significantly affect metabolic body homeostasis and patients hemodynamic status, setting the stage for true medical emergencies. The therapeutic approach should be first aimed at early correction of concurrent clinical problems (e.g. fluids and hemodynamic optimization in case of shock, mechanical ventilation in case of concomitant respiratory failure, hemodialysis for acute intoxications etc.), in parallel to the formulation of a diagnosis. In case of severe acidosis, the administration of alkalizing agents should be carefully evaluated, taking into account the risk of side effects, as well as the potential need of renal replacement therapy.

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

    Inborn errors of metabolism may impact on muscle and peripheral nerve. Abnormalities involve mitochondria and other subcellular organelles such as peroxisomes and lysosomes related to the turnover and recycling of cellular compartments. Treatable causes are β-oxidation defects producing progressive neuropathy; pyruvate dehydrogenase deficiency, porphyria, or vitamin B12 deficiency causing recurrent episodes of neuropathy or acute motor deficit mimicking Guillain-Barré syndrome. On the other hand, lysosomal (mucopolysaccharidosis, Gaucher and Fabry diseases), mitochondriopathic (mitochondrial or nuclear mutations or mDNA depletion), peroxisomal (adrenomyeloneuropathy, Refsum disease, sterol carrier protein-2 deficiency, cerebrotendinous xanthomatosis, α-methylacyl racemase deficiency) diseases are multisystemic disorders involving also the heart, liver, brain, retina, and kidney. Pathophysiology of most metabolic myopathies is related to the impairment of energy production or to abnormal production of reactive oxygen species (ROS). Main symptoms are exercise intolerance with myalgias, cramps and recurrent myoglobinuria or limb weakness associated with elevation of serum creatine kinase. Carnitine palmitoyl transferase deficiency, followed by acid maltase deficiency, and lipin deficiency, are the most common cause of isolated rhabdomyolysis. Metabolic myopathies are frequently associated to extra-neuromuscular disorders particularly involving the heart, liver, brain, retina, skin, and kidney. Copyright © 2013 Elsevier B.V.

  18. Metabolic Acidosis and Subclinical Metabolic Acidosis in CKD.

    Metabolic acidosis is not uncommon in CKD and is linked with bone demineralization, muscle catabolism, and higher risks of CKD progression and mortality. Clinical practice guidelines recommend maintaining serum total CO2 at ≥22 mEq/L to help prevent these complications. Although a definitive trial testing whether correcting metabolic acidosis improves clinical outcomes has not been conducted, results from small, single-center studies support this notion. Furthermore, biologic plausibility supports the notion that a subset of patients with CKD have acid-mediated organ injury despite having a normal serum total CO2 and might benefit from oral alkali before overt acidosis develops. Identifying these individuals with subclinical metabolic acidosis is challenging, but recent results suggest that urinary acid excretion measurements may be helpful. The dose of alkali to provide in this setting is unknown as well. The review discusses these topics and the prevalence and risk factors of metabolic acidosis, mechanisms of acid-mediated organ injury, results from interventional studies, and potential harms of alkali therapy in CKD.
