Assessment of Cinnamaldehyde's Potency on Heat Stress-induced Testicular Impairments in Wistar Rats.

Background: Male sterility results from high testicular temperatures, which affect mammalian spermatogenesis. High testicular temperatures affect sperm motility, morphology and fertility according to their magnitude and duration.

Aim: The aim of the current study is to examine the effects of heat-induced oxidative stress and cinnamaldehyde on Wistar rat testicular structure and function.

Role of Thymoquinone on sleep restriction and its mitigating effect on leptin-mediated signaling pathway in rat brain.

Background: Sleep and stress interact bidirectionally by acting on brain circuits that affect metabolism. Sleep and its alterations have impact on blood leptin levels, metabolic hormone that regulates appetite. Brain expresses the receptors for the peptide hormone leptin produced from adipocytes.
