During evolution, the ability to overeat and store the extra energy as glycogen and lipids in specialized tissues must have conferred a reproductive advantage by releasing animals from the need to eat constantly, enabling them to engage in behaviors that improved reproductive success. Mechanisms that inhibited ingestive behavior might have been most adaptive when they caused individuals to stop...
Background: Oxcarbazepine is a widely used novel antiepileptic drug . In vitro electrophysiology studies indicate that oxcarbazepine produced blocked of voltagesensitive sodium channels , resulting in stabilization of hyper exited neural membranes , inhibition of propagation of synaptic impulses . In this research the effect of oxcarbazepine has been studied on the amount LH , FSH , testosteron...
BACKGROUND Female sex hormones are known to have immunomodulatory effects. Therefore, reproductive factors and exogenous hormone use could influence the risk of multiple myeloma in women. However, the role of hormonal factors in multiple myeloma etiology remains unclear because previous investigations were underpowered to detect modest associations. METHODS We conducted a pooled analysis of s...
Hormones must be balanced and dynamically controlled for the Female Reproductive Tract (FRT) to function correctly during menstrual cycle, pregnancy, delivery. Gamete selection successful transfer uterus, where it implants pregnancy occurs, is supported by mucosal epithelial lining of FRT ovaries, cervix, fallopian tubes, vagina. Successful implantation placentation in humans other animals rely...
Oestrogenic steroid hormones (‘oestrogens’) have a crucial role in cellular regulation in all vertebrate species. The levels required to bring about such changes are very low, around 0.1–1 pg/ml (picograms per millilitre) of serum. It has been known for over five decades that oestrogens affect the development of the male reproductive system of mammals (Zuckerman, 1940). Nonetheless, oestrogenic...
