This study aimed to evaluate kaempferol's, a dietary flavonoid widely present in plants, potential impact on nonalcoholic fatty liver disease (NAFLD) and its underlying mechanisms. In this study, 60 adult male rats were used and divided into a control group receiving a standard pellet diet, a kaempferol-treated group receiving kaempferol (250 mg/kg), a high-fat diet (HFD) group receiving HFD, and a kaempferol-treated HFD group. At the end of the experiment, the total lipid profile and liver enzymes were assayed in the serum.

Selenium protects against nesfatin-1 modulation of the hypothalamic-pituitary-testicular axis during hypothyroidism in male rats.

Normal gonadal function can be disrupted by hypothyroidism. Hypothyroidism disturbs testicular function directly and centrally by affecting the hypothalamic-pituitary-testicular axis with unclear mechanism. As nesfatin-1 neurons co-localized with TRH and GnRH neurons in the hypothalamus, it could play a role in centrally hypothyroidism induced testicular dysfunction.
