Alcohol related health challenges have lingered over the years. Such associated with locally brewed alcoholic beverages received little attention. The urgency to explore this becomes imperative. This study aimed at evaluating effect of regular consumption local on estrous cycle and histological image ovaries uterus thus fertility female albino rats. Thirty screened rats weighing 180-220g were d...

Introduction: To investigate the effects of predictable and unpredictable external perturbations on cortical activity in healthy young and older adults. Methods: Twenty healthy older and 19 healthy young adults were exposed to predictable and unpredictable external perturbations, and their cortical activity upon postural recovery was measured using a 32-channel quantitative encephalography. Th...

Reproduction is adversely affected by alcohol abuse in humans and laboratory animals. In rats, alcohol exposure suppresses both luteinizing hormone (LH) and sex steroid secretion, although consensus is lacking as to which level of the hypothalamic-pituitary-gonadal (HPG) axis is primarily affected. We tested the hypothesis that acute alcohol treatment inhibits the HPG axis by blunting release o...

The short and long forms of prolactin receptor (PRL-R) mRNA have been detected in the female rat brain. The present study aimed to investigate: (1) if the PRL-R mRNA is expressed in the male rat brain; (2) if expression levels in the female brain vary during the estrous cycle. All animals were sacrificed between 12:00 and 14:00 h. Radioactive RNase protection assay was used to measure mRNA leve...

A novel factor of interest for growth/plasticity in the brain is pregnane xenobiotic receptor (PXR). PXR is a liver factor known for its role in xenobiotic clearance and cholesterol metabolism. It is expressed in the brain, suggesting a potential role for plasticity, particularly involving cholesterol-based steroids and neurosteroids. Mating induces synthesis of neurosteroids in the midbrain Ve...

Growth differentiation factor 9 (GDF-9) and bone morphogenetic protein 15 (BMP-15) play important functions in follicular and oocyte development in many species. This study evaluated the dynamic expression of GDF-9 and BMP-15 in canine follicles cells using flow cytometry analysis. Follicular cells were removed from three sizes of antral follicles (small, medium and large) from ovaries of bitch...

Orexins are peptides controlling feeding, sleep, and neuroendocrine functions. They are synthesized by the hypothalamus with projections throughout the brain. Orexins and their orexin 1 (OX(1)) and orexin 2 receptors (OX(2)) are present outside the central nervous system. Here the expression of preproorexin (PPO), OX(1), and OX(2) was studied in rat ovaries. PPO, OX(1), and OX(2) were determine...

Rising serum estradiol triggers the surge release of gonadotropin-releasing hormone (GnRH) at late proestrus leading to ovulation. We hypothesized that evokes alterations in peptidergic signaling onto GnRH neurons inducing a differential expression neuropeptide-, growth factor-, and orphan G-protein-coupled receptor (GPCR) genes. Thus, we analyzed transcriptome collected from intact, proestrous...
