Underlying biochemical effects of intermittent fasting, exercise and honey on streptozotocin-induced liver damage in rats.

Purpose: Derangements of liver transcriptional factors and enzymes have important implications in diabetes-induced related complications. Hence, this study which consists of two experimental phases was aimed at evaluating the possible underlying molecular mechanisms of intermittent fasting (IF), exercise starvation and honey in streptozotocin (STZ)-mediated liver damage in diabetic rats.

Methods: The diabetic rats were treated orally with distilled water (0.

Possible mechanisms involved in the testicular-protective property of quercetin in rats exposed to endosulfan toxicity.

The study investigated the effects of quercetin and putative mechanisms involved against endosulfan-testicular impairments in rats. Rats were allotted into five treatment groups (n = 5). Groups 1-2 had normal saline and maize oil (vehicle) (10 mL/kg), group 3 received quercetin (20 mg/kg), 4-5 had endosulfan (5 mg/kg, p.

Therapeutic efficacy of N-acetylcysteine and zinc sulphate against di-(2-ethylhexyl) phthalate-induced testicular oxido-nitrergic stress in male Wistar rat.

The therapeutic efficacy of N-acetylcysteine (NAC) and zinc sulphate on di-(2-ethylhexyl) phthalate (DEHP)-induced testicular oxido-nitrergic stress in rats was investigated in 36 male Wistar rats (170 ± 10 g) randomly assigned into one of six groups (n = 6). Group 1 (control) received 2.5 ml/kg of distilled water for 42 days, while group 2 (vehicle) received 2.

d-ribose- l-cysteine abrogates testicular maladaptive responses induced by polychlorinated bisphenol intoxication in rats via activation of the mTOR signaling pathway mediating inhibition of apoptosis, inflammation, and oxidonitrergic flux.

Male reproductive maladaptive responses are becoming a global health concern and also a social issue. Polychlorinated biphenyls (PCBs) are a member of halogenated aromatic environmental pollutants with diverse environmental matrices. This study was conducted to explore the mechanisms of PCBs-induced testicular maladaptive responses and the potential reversal effects of d-ribose- l-cysteine (DRLC) on testicular injury induced by administration of PCBs (2 mg/kg) for 30 days.

Effects of methotrexate on serum testosterone level in sleep deprived male Wistar rats.

Background: Sleep deprivation has been reported to decrease testosterone levels but the mechanism remains unclear. Studies have shown that sleep deprivation increases interleukin 1 beta (IL-1β), a pro-inflammatory cytokine and that increased IL-1β levels cause reductions in Leydig cell production of testosterone. This study was therefore designed to determine the effects of methotrexate, an IL-1β blocker on serum testosterone levels in sleep deprived male Wistar rats.
