OBJECTIVE: We tested the hypothesis that glucocorticoid (GC) exposure in female rats would lead to glucose dysregulation and elevated cardiac inflammatory biomarkers, which are dipeptidyl peptidase-4 (DPP-4)- and glycogen synthase kinase-3 (GSK-3)-dependent. METHODS: Female Wistar rats received vehicle (control; n = 6) or GC (dexamethasone; n = 6; 0.2 mg/kg; p.o.) for six days. Insulin resistance was determined by HOMA-IR. DPP-4 activity was determined by fluorescence method, whereas vascular cell adhesion molecule-1 (VCAM-1), uric acid, malondialdehyde (MDA), lactate dehydrogenase (LDH) and nitric oxide (NO) from plasma and cardiac homogenate were estimated as cardiac pro-inflammatory biomarkers...

The aim of this case-control study was to assess TIMP2 level in subjects with or without metabolic syndrome (MetS) and to associate levels with non-alcoholic fatty liver changes (NAFLD). Thirty-three MetS subjects and 55 controls were recruited. Anthropometric data, lipid and glucose profile, TIMP2 and liver ultrasound was performed. High TIMP2 was seen in MetS group (145.28 ± 23.11 pg/ml) versus controls (19.06 ± 1.19 pg/ml; p < .001). Serum cholesterol, triglyceride, LDL-c and glucose levels were significantly higher in MetS subjects (p < ...

OBJECTIVE: To evaluate the effect of the administration of phytoestrogens on obesity, type 2 diabetes, and liver-kidney toxicity. METHODS: Phytoestrogens (phyto(E2)) were administrated to high fructose-fat diet (HFFD). RESULTS: This study showed that administration of phyto(E2) to HFFD-mice inhibited lipase activity by 34%, decreased body weight by 20% and modulated lipid profile, showed a decrease in total-cholesterol (TC) and LDL-cholesterol (LDL-C) rates in the plasma by 59% and 42%, respectively, and increased the HDL-cholesterol (HDL-C) level by 31%...

In this study, we assess the impact of Salvia officinalis essential oil on renal toxicity induced by vanadium in rats. The animals were exposed to either ammonium metavanadate (5 mg/kg body weight) or the combination of vanadium and S. officinalis essential oil (15 mg EO/kg body weight) for 10 days. Vanadium induced significant renal damage, demonstrated by increased plasma levels of urea and creatinine. A marked increase in lipid peroxidation markers and carbonyl protein levels with a significant decrease in enzymatic antioxidants (SOD), catalase (CAT), and glutathione peroxidase (GPx) was also observed in vanadium-treated rats...

This research aimed to evaluate the anti-diabetic effects of β-d-mannuronic acid (M2000) on blood glucose, insulin production, and inflammatory markers in streptozotocin-induced diabetic rats. Our data showed that the final fasting serum glucose level was significantly lower in the M2000-treated group compared to the diabetic control group (p < .05). In addition, the final fasting serum insulin level significantly increased in the M2000-treated group compared to the diabetic control group (p < ...

CONTEXT: Maternal diet composition could influence fetal organogenesis. OBJECTIVE: We investigated effects of high fat diet (HFD) intake alone or combined with omega 3 during pregnancy, lactation and early days of weaning on nephrogenesis of pups and maternal renal function and morphology. MATERIAL AND METHODS: Mothers and their pups included in each group were supplied with the same diet composition. Rats were divided into group I, II and III supplied with chow of either 10 kcal%, 45 kcal% or 45 kcal% from fat together with omega-3 respectively...

BACKGROUND: Paraoxonase 1 (PON1: EC 3.1.8.1) is a vital antioxidant enzyme against mainly atherosclerosis and many other diseases associated with oxidative stress. Thus, studies related to PON1 have an important place in the pharmacology. In this study, we aimed to evaluate the in vitro inhibition effects of some indazoles on the activity of human PON1. METHODS: PON1 was purified from human serum with a specific activity of 5000 U/mg and 13.50% yield by using simple chromatographic methods...

OBJECTIVE: Type I diabetes is a disease characterised by an extreme reduction in serum insulin levels. Diet and exercise have gained considerable attention in the treatment of diabetes. Therefore, this study was carried out to investigate the effect of diet with carbohydrate but without daily energy restriction on various metabolites (glucose, triglycerides, cholesterol, lactate), some electrolytes (Ca, Mg, Na, K, P, Cl) and essential metals (Mn, Co, Cu, Se, Zn, Fe) in the blood of rats with streptozotocin-induced diabetes...

HCC has been reported to be immensely occurring carcinoma worldwide. Recent days the mortality occurred due to liver cancer has also been found to be increased at an alarming speed affecting mostly the young patients. The aim of the current study was to decipher the role of calcium and vitamin K3 in the treatment of chemically induced hepatocarcinogenesis in the male Wistar rats. Liver cancer was induced via a subnecrogenic dose of 160 mg/kg body weight, diethylnitrosamine (DENA) when associated with fasting/refeeding in male Wistar rats...

The objective of this study is to explore the preventive effects of ethyl acetate fraction from Citrus aurantium leaf extract (EACA), associated with its phytochemical content, against the toxic impacts of acute exposure to carbon tetrachloride (CCl4 ) in the liver of adult rats. HPLC analysis of ethyl acetate fraction from extract C. aurantium revealed eight compounds. Administration of a single dose of CCl4 caused hepatoxicity as monitored by an increase in lipid peroxidation (thiobarbituric acid reactive substances) and in protein carbonyl level but a decrease in antioxidant markers in the liver tissue...

This study investigated the effects of chronic supraphysiological dose of testosterone propionate administration cardiovascular function in rats from the perspective of haemostatic function including platelet functions, coagulation, and fibrinolysis. Testosterone significantly enhanced cardiac contractility by enhancing LVSP (10%), dp/dtmax (36.7%), dp/dtmin (14.6%) without altering heart rate, diastolic function, and serum lipid profile. While it has no effect on platelets count, thromboxane B2 levels, and platelet aggregation, testosterone significantly enhanced bleeding time and increased circulatory and thoracic aorta mRNA and protein levels of tPA (46...
