Presently, demyelinating diseases have been reported to affect the reproductive life of patients who suffer from them, but the progression of the alterations is unknown, especially in men. To better understand these effects, it is necessary to perform studies in animal models, such as the male rat, which exhibits progressive demyelination of the central nervous system, altered kisspeptin expression at the hypothalamic level, and decreased luteinizing hormone, which could alter sperm quality and testicular diameter. Thus, the objective of the present study was to analyze the diameter of the seminiferous tubules, the sperm motility, and the testosterone levels of 90-day-old male rats. The obtained results indicate that male rats show an increase in testicular size accompanied by an increase in the diameter of the seminiferous tubules of the left testicle. There was also a decrease in progressive motility in sperm samples from the left epididymis of male rats compared to the control group, with no changes in serum testosterone concentration. Therefore, we conclude that male rats with central demyelination show altered testicular diameter and decreased motility in sperm from the left side. This type of studies serves as a basis for proposing possible reproductive strategies to improve the fertility and testicular function of men with demyelinating diseases of the central nervous system.

Background: Aging is caused by the progressive accumulation of various changes in the body, which is associated with an increase in free radicals and oxidative stress (OS). The aim of this study was to investigate the potential of caloric restriction (CR) and quercetin (QUER) in alleviating OS in aging and the involvement of the NAD (P) H quinone oxidoreductase 1 (NQO1)/SIRT1 signaling pathway in these effects.
Methods: Two age groups of male Wistar rats (eight and 20 weeks of age) were included in the study and subdivided into normal diet (ND), ND with QUER (15 mg Kg, IP), ND with CR, and ND with QUER and CR groups.
Sympathetic innervation of interscapular brown adipose tissue is not a predominant mediator of Oxytocin (OT)-elicited reductions of body weight gain and adiposity in male diet-induced obese rats.

Recent studies indicate that central administration of oxytocin (OT) reduces body weight (BW) in high fat diet-induced obese (DIO) rodents by reducing energy intake and increasing energy expenditure (EE). Previous studies in our lab have shown that administration of OT into the fourth ventricle (4V; hindbrain) elicits weight loss and stimulates interscapular brown adipose tissue temperature (T) in DIO rats. We hypothesized that OT-elicited stimulation of sympathetic nervous system (SNS) activation of IBAT contributes to its ability to activate BAT and reduce BW in DIO rats.

Background: Growing evidence indicates that disruptions in mitochondrial quality management contribute to the development of acute kidney injury (AKI), incomplete or maladaptive kidney repair, and chronic kidney disease. However, the temporal dynamics of mitochondrial quality control alterations in relation to renal injury and its recovery remain poorly understood and are addressed in this manuscript.
Method: ology: Male Wistar rats (n = 60) were subjected to varying durations of ischemia and reperfusion.

Ya That Somdun (YTS) is a traditional Thai medicine composed of six herbs used as a strengthening tonic. Some of the herbs constituting YTS have antihyperlipidemic and anti-obesity activities. The objective of this study was to elucidate the antihyperlipidemic properties of YTS extract in rats with cholesterol suspension-induced hyperlipidemia.
