Supplementation plays an important role in reversing the weight loss of grazing yaks during cold season. However, little is known about the effect of supplementation on the serum metabolites of grazing yaks. The objective of this study was to explore the effects of supplementary feeding on average daily gain (ADG) and serum metabolites with nuclear magnetic resonance (NMR)-based metabolomics method in growing yaks during cold season on the Qinghai-Tibetan plateau. Twenty 1.5-year-old female yaks (91.38 ± 10.43 kg LW) were evenly divided into three treatment groups and a control group (CON) (n = 5 per group). All the yaks were released to graze during daytime, whereas the yaks in the treatment groups were supplemented with highland barley (HLB), rapeseed meal (RSM), and highland barley plus rapeseed meal (HLB + RSM) at night. The whole experiment lasted for 120 days. Results indicated that the ADG of growing yak heifers was increased by concentrate supplementations, and ADG under HLB and HLB + RSM group was 37.5% higher (p < 0.05) than that with RSM supplementation. Supplementary feeding increased the plasma concentrations of total protein (TP), albumin (ALB), and blood urea nitrogen (BUN) of those in the CON group, and concentrations of BUN were higher in the RSM group than in the HLB and HLB + RSM group. Compared with the CON group, serum levels of glutamine, glycine, β-glucose were lower and that of choline was higher in the HLB group; serum levels of lactate were lower and that of choline, glutamate were higher in the HLB + RSM group. Compared with the HLB + RSM group, serum levels of glycerophosphoryl choline (GPC) and lactate were higher, and those of choline, glutamine, glutamate, leucine, N-acetyaspartate, α-glucose, and β-glucose were lower in the HLB group; serum levels of citrate, GPC and lactate were higher, and those of 3-Hydroxybutyrate, betaine, choline, glutamate, glutamine, N-acetylglycoprotein, N-acetyaspartate, α-glucose, and β-glucose were lower in the RSM group. It could be concluded that concentrate supplementations significantly improved the growth performance of growing yaks and supplementation with HBL or HLB plus RSM was better than RSM during the cold season. Supplementation with HBL or HLB plus RSM affected the serum metabolites of grazing yaks, and both treatments promoted lipid synthesis. Supplementation of yaks with HBL plus RSM could improve energy-supply efficiency, protein and lipid deposition compared with HLB and RSM.

β-glucuronidase (BG) activity is a promising biomarker for diagnosis and prognosis after exposure to organophosphorous (OP) pesticides. The aim of this study was to evaluate the changes in serum BG activity in patients with acute OP poisoning and to determine whether these changes correlate with the severity of poisoning. Thirty patients with anticholinesterase pesticide poisoning were included, besides 10 healthy volunteers as a control group. Serum activities of butyrylcholinesterase (BuChE) and BG were measured for each subject on admission, then after 12 and 24 h. Serum levels of BuChE and BG in poisoned patients were significantly different from the control subjects; these differences persisted in repeated measurements. Moreover, the serum levels showed significant differences within each group of the three time points. A significant negative correlation was found between the serum activities of BuChE and BG in all groups at the three time points. In conclusion, serum BG activity seems a reliable marker for OP poisoning even when measured at 24 h after poisoning.

Abstract To study the mechanism of Tim-3 on immune escape in benzene-induced acute myeloid leukemia (AML), to provide potential targets of clinical monitoring and intervention of hematological toxicity in benzene-induced AML . C3H/He mice were randomly divided into control group and experimental group. Serum levels of IL-12 in the experimental group were significantly lower than that in the control group. Serum levels of TGF-β1 in the experimental group were significantly higher than that in the control group( p <0.05). The proportion of Tim-3 positive CD14 + monocytes of bone marrow and spleen in the experimental group were both significantly higher than that in the control group ( p <0.05) by Flow cytometry (FCM). Compared with the control group, the expression of Tim-3 on (M1+M2) macrophages of bone marrow in the experimental group significantly increased by immunofluorescence assay. The expression of type M2 macrophages in (M1+M2) macrophages of bone marrow and spleen tissues in the experimental group were both higher than that in the control group. The expression levels of p-PI3K, p-AKT and p-mTOR in the experimental group were all significantly higher than that in the control group. Tim-3 was highly expressed in macrophages in benzene-induced AML. It promoted the activation of PI3K/AKT/mTOR signaling pathway, stimulated the secretion of anti-inflammatory cytokines, and inhibited the secretion of pro-inflammatory cytokines. High expression of Tim-3 changed the phenotype and function of macrophages by promoting the macrophages polarization, thus inducing negative immune response in the tumor microenvironment and tumor immune escape.

In spite of its long half life, phenobarbital is still given twice-daily in the treatment of generalized tonic-clonic epilepsy. This study aims to determine if daily dose of phenobarbital given once differs to that given twice daily. Subjects of this unblinded controlled clinical trial were generalized tonic-clonic epilepsy patients ranging in age from 1-15 years. There were 40 study cases and 42 controls. We gave phenobarbital 4-6 mg/kg/day once-daily for study group and twice-daily dose for control group. History, physical and EEG examination and phenobarbital plasma measurements were obtained a t the beginning of the study and four weeks later. The ratio of the second to first phenobarbital plasma concentrations in the study group was 0.99 while in the control group it was 1.02. The proportion of seizure-free patients in the study group increased from 70% at the beginning to 85% at the end of study, and in the control group from 64.3% to 83.3%. Hyperactivity and irritability increased in both groups, and there were no significant differences in mean serum levels, seizures control, hyperactivity and irritability in both groups. Drowsiness was found in 50% of cases, but statistically significant decrease were found in study group. The compliance of the study group (92.5%) was significantly better than that of the control group (71.4%).

Abstract Background: Subjects with normal weight obesity (NWO) are supposed to cardiometabolic disorders. The aim of this study was to investigate the circulating levels of vaspin and leptin and their association with glycemic and lipid profiles in women with NWO compared to controlsMethods: Forty women with body mass index (BMI)=18.5-24.9 kg/m2 and fat mass (FM) ≥ 30% as NWO group and 30 age matched women with same BMI range and FM<30% as control group were enrolled in this study. Anthropometric measurement, fasting serum levels of blood sugar (FBS), insulin, Glycated hemoglobin (HbA1c), lipid profiles and also, leptin and vaspin were measured.Results: The mean ± standard deviation (SD) of age was 28.76 ± 4.76 years in NWO group and 29.23 ± 4.50 years in controls. Subjects in NWO group had higher serum levels of insulin (9.02 ± 4.75 vs.6.24 ± 2.51, p= 0.009), leptin (17.31 ± 8.10 vs. 9.94 ± 4.30, p<0.001) and homeostatic model assessment for insulin resistance (HOMA-IR) (33.77 ± 20.71 vs. 23.48 ± 10.03, p=0.009) as compared to normal weight non-obese (NWNO) as control group. Serum level of vaspin in NWO group (34.82 pg/ml) was higher than that in controls (27.72 pg/ml), (p=0.12). In NWO group, serum level of leptin was correlated positively with FBS (r=0.45, p=0.02), insulin (r=0.51, p=0.008), and HOMA-IR (r=0.46, p=0.02) and vaspin concentration was positively associated with insulin (r=0.36, p= 0.02) and HOMA-IR (r=0.30, p=0.06). Conclusion: We observed that concentration of insulin and HOMA-IR index were significantly increased in women with NWO compared to the controls. Higher levels of leptin and vaspin in NWO were associated with glycemic profiles in NWO group.

Multiple sclerosis (MS) is the most common neurological disease that happens at a young age. MS is an inflammatory disease; associated with the demyelination of the central nervous system. Therefore, some inflammatory factors are effective in the mechanism and progression of the disease. Melatonin, as a multi-effect substance including anti-inflammatory effects, can reduce symptoms of MS in patients with a change in their inflammatory factors level. In this study, 50 MS patients who were referred to the MS Society of Markazi Province were randomly selected. All patients were treated with routine MS treatment (interferon) and were divided into control (25 placebo recipients) and treatment (25 recipients of 3 mg melatonin per day for 24 weeks) groups. Anthropometric data of patients including height, weight, and age were determined. Blood samples were collected after fasting in order to determine serum levels of interleukin 1 beta (IL-1β) and tumor necrosis factor-alpha (TNF-α). Then, samples were immediately centrifuged for serum separation and sera were transferred to a freezer at -80°C and serum levels of these factors were determined; using ELISA kit. The results of this study showed that there was no significant difference between the control and treatment groups in terms of serum levels of TNF-α. However, the level of IL-1β was significantly reduced in the treatment group compared to the control group, indicating that melatonin decreases this inflammatory substance. Our findings suggest a valuable strategy in the treatment of patients who suffer from MS

Purpose: To study the influence of N-acetylcysteine (NAC) on systemic lupus  erythematosus (SLE) mice, and the mechanism(s) involved. Methods: Fourteen MRL/lpr SLE mice aged 5 weeks (mean weight = 20.35 ± 2.12 g) were divided into two 7-mouse groups: SLE (control) and treatment groups. The control group comprised healthy female SPF-grade C57BL/6 mice (n = 7). The treatment group mice received intraperitoneal injection of NAC at a dose of 250 mg/kg daily for 8 weeks. The serum levels of malondialdehyde (MDA) and nitric oxide (NO), and activities of glutathione peroxidase (GPx) and superoxide dismutase (SOD), were assayed using standard methods. The level of urine protein and activity of anti-double stranded (ds) DNA antibody were determined using their respective enzyme-linked assay (ELISA) kits. Results: The spleens of mice in SLE mice were significantly enlarged, relative to control mice, but they were reduced significantly by NAC (p < 0.05). N-Acetylcysteine (NAC) also significantly reduced the serum levels of MDA and NO in SLE mice, but significantly  increased the serum activities of superoxide dismutase and GPx. Moreover, urine protein concentration and activity of anti-dsDNA antibody in SLE mice significantly increased, but reduced significantly by NAC treatment (p < 0.05). Conclusion: These results suggest that NAC effectively alleviates SLE in mice via regulation of oxidative stress. Thus, NAC has the potentials for development into a therapy for the management of SLE.

Evidence showed that chronic inflammatory and immunopathological responses play a pivotal role in the development of osteoarthritis (OA). Interleukin-38 (IL-38) as a novel antiinflammatory cytokine with influential modulatory properties on both innate and adaptive immune responses can be involved in the pathogenesis of OA. Therefore, this study aimed to measure the serum level of IL-38 in OA patients to clarify the positive or negative association with disease and its severity. Blood specimens were collected from two groups including 23 newly-diagnosed OA patients and 22 healthy sex and age-matched subjects as a control group. Serum IL-38 quantities were measured using enzyme-linked immunosorbent assay (ELISA). Significantly higher IL-38 levels were detected in OA patients in comparison with the healthy group (265.78±41.27 pg/mL vs 44.23±6.04 pg/mL, p=0.0001). The IL-38 concentration in OA patients with Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) scores>40 and in OA patients with visual analog scale (VAS) scores>5 were higher than those with WOMAC scores<40, and VAS scores<5 (p=0.026 and p=0.035, respectively). The IL-38 levels in OA patients with body mass index (BMI)<25 were also significantly higher than in patients with BMI>25 (p=0.05). According to our findings, WOMAC, VAS, and BMI indices may influence the IL-38 serum levels in OA patients and it may be elevated in OA patients to modulate inflammatory responses in a compensatory manner. The patients with OA, especially those with more severe disease express higher serum amounts of IL-38. Accordingly, IL-38 may be considered as a valuable marker for OA.

Background: Variability in glucagon-like peptide (GLP)-1 and GLP-2 plasma concentrations has been suggested in Celiac disease (CD), with inconclusive results. We assessed the association between serum levels of GLP-1 and GLP-2 and their duodenal receptor expression in children with and without CD. Methods: This was a two-part, cross-sectional and prospective cohort study. Group assignment, performed after duodenal samples for mRNA expression of GLP-1 receptor (GLP1R) and GLP-2 receptor (GLP2R), were taken during esophagogastroduodenoscopy. The control group consisted of patients with normal endoscopy and negative serology. The CD group consisted of patients with positive serology and endoscopy suggestive of CD. All had an oral glucose-tolerance test (OGTT). CD patients underwent a second OGTT after 6 months of a gluten-free diet (GFD). Results: The CD group included 12 patients; 7 males with mean age 9.2 ± 2.5 years. The control group included 10 patients; 5 males with mean age 12 ± 4 years, ( p = 0.14). No differences were detected in basal or peak levels of GLP-1 or GLP-2 between control, naïve CD (before GFD) and treated CD (after GFD) groups. Expression of GLP1R and GLP2R mRNA was similar. Significant positive correlations between glucose and C-peptide secretion ( r = 0.9, p < 0.01) and GLP-1 and GLP-2 ( r = 0.8, p = 0.01) were detected in the control group. Significant negative correlations were found in the naïve CD group between GLP2R expression and glucose secretion ( r = −0.68, p = 0.015) and GLP1R expression and serum GLP-1 ( r = −0.7, p = 0.016). Conclusions: Although no significant differences were detected in secretion patterns or gut receptor expression of GLP-1 and GLP-2 in healthy versus CD pediatric patients, the detected discrepancy between the ligand levels and their tissue receptors requires additional study.
