Twenty-one Spraque Dawley rat pups were randomly assigned into three groups, seven rats in each. All the rats except for those in the control group were injected subcutaneously with a single dose of sodium selenite on postpartum day 9. On days 10-14, rats in the sham group were intraperitoneally administered 50 mg/kg/day saline solution, while rats in the sesamol group were given 50 mg/kg/day sesamol by the same route. Following cataract grading, the lenses and capsules were extracted and the mean levels of reduced glutathione (GSH), malondialdehyde (MDA), total antioxidant status (TAS) and total oxidant status (TOS) in lens supernatants were biochemically analyzed. The control group did not show any development of cataract. It was found that the mean cataract grade in the sesamol group was significantly lower than that of the sham group (p<0.05). The mean GSH level and TAS in the sesamo...

Serum copeptin, AG and GU levels were screened in 128 patients who were admitted to emergency department with suicide attempts and 59 healthy controls. Beck Anxiety Inventory (BAI) and Beck Depression Inventory (BDI) were applied simultaneously, and the data were compared statistically. AG, UG and copeptin levels were higher in the patient group compared with the healthy control group. BAI scores of patients were found to be positively correlated with BDI scores. While there was a significant difference (p=0.0064) between psychiatric and non-psychiatric patients with suicide attempts in terms of BAI scores, there were no differences in BDI scores and levels of biomarkers. We found significantly increased BDI and BAI scores and increased levels of AG, UG and copeptin in psychiatric and n...

Ghrelin has anti-inflammatory effects, and its level is altered in obesity and inflammatory diseases. The aim of the study was to evaluate the prevalence of obesity and ghrelin and obestatin levels in patients with Behçet's disease (BD). One hundred and forty-three (143) patients with BD and 112 healthy controls (HC) were enrolled. Participants were subdivided according to the body mass index (BMI) as lean (<18.5 kg/m(2)), normal weight (18.5-24.9 kg/m(2)), overweight (25-29.9 kg/m(2)) and obese (≥30 kg/m(2)). In addition to the routine evaluations (fasting blood glucose, lipid profile, and kidney and liver function tests), serum acylated-ghrelin (AG), unacylated-ghrelin (UAG), total ghrelin (TG) and obestatin levels were analyzed. Student's t-test and chi-square test were used for statistical analysis. The prevalence of obesity was relatively lower in the BD group than in the HC group (12.6% vs. ...

The study included 80 patients with ischemic stroke (IS), 40 patients with intracranial hemorrhage (ICH), 80 patients with metabolic disorder induced impaired consciousness (MDIC) and 40 healthy controls. The levels of UCH-L1 [median (IQR)] were as follows: 5.59ng/mL (3.90-9.37) in IS, 5.44ng/ml (4.01-13.98) in ICH, 3.34ng/ml (2.29-5.88) in MDIC and 3.94ng/ml (3.31-7.95) in healthy volunteers. Significantly higher levels were detected in IS and ICH than in MDIC and healthy volunteers. In ROC curve analysis, we detected 63.75% sensitivity and 62.5% specificity (AUC=0.626, p<0.0199, 95% CI: 0.533-0.713) with a cutoff value of 4.336ng/ml for IS and 75% sensitivity and 55% specificity (AUC=0.664, p<0.0071, 95% CI: 0.549-0.766) with a cut-off value of 4.036ng/ml for ICH. However, the sen...

Twenty-eight Spraque-Dawley rat pups were assigned into four groups. All the rats, except for those in the control group, were injected subcutaneously sodium selenite to induce experimental cataract on the postpartum ninth day, and between 10(th) and 14(th) days. Rats in the sham, EGCG, and EA groups were intraperitoneally administered 50 mg/(kg·d) saline solution, 50 mg/(kg·d) EGCG and 200 mg/(kg·d) EA, respectively. The reduced glutathione (GSH) and malondialdehyde (MDA) levels, total antioxidant status (TAS) and total oxidant status (TOS) in lens supernatants were measured. The mean cataract gradings in EGCG and EA groups were found to be significantly lower than that in sham group (P<0.001). The mean GSH levels and TASs in EGCG and EA groups were significantly higher than that in sham group while mean MDA levels and TOSs in EGCG and EA group...

Blood samples were obtained from the patients prior to imaging to determine the levels of copeptin. Patients were divided into diagnostic groups after the imaging. One hundred and seventy-six participants, who were enrolled in the study, were as follows: 50 cerebral infarction (CI) patients (M/F: 24/26), 47 intracranial hemorrhage (ICH) patients (M/F: 27/20), 29 subarachnoid hemorrhage (SAH) patients (M/F: 17/12) and 50 healthy controls. Differences and correlations between groups were analyzed. Plasma levels of copeptin in patients with CI, ICH, and SAH were 5.49 ng/dL (IQR 4.73 to 6.96), 4.50 ng/dL (IQR 3.04 to 9.77), and 5.90 ng/dL (IQR 3.11 to 13.26), respectively. It was found to be 2.0 ng/dL (IQR 1.57 to 2.5) in healthy volunteers. There was no significant correlation between copeptin levels and Intracerebral Hemorrhage Score (ICHS) (r = 0.231, p = 0.118). However, significant positive correlation was found between copeptin levels with the National Institutes of Health Stroke Scale (NIHSS) (r = 0.365, p = 0.009) and the BotterelHunt and Hess Scale (BHHS) (r = 0.590, p = 0.001). The copeptin levels of 41 (32.5%) patients who died were found to be significantly higher than those 85 (67.5%) patients who were discharged (p &amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;lt; 0.001). Copeptin levels in patients with CI, ICH, and SAH are significantly higher than healthy volunteers, but the plasma level of copeptin is not decisive in the discrimination of CI, ICH, and SAH.
