Menopausal women display changes in the osseous tissue (osteoporosis, pathologic fractures) and disorders in the function of cardiovascular system (hypertension, cardiovascular disease, arteriosclerosis, calcification). Additionally, interdependence was observed between the loss of osseous tissue and disordered circulation, but the mechanism of the interdependence has never been fully recognize...

Intrauterine growth restriction (IUGR) is closely linked with metabolic diseases, appetite disorders and obesity at adulthood. Leptin, a major adipokine secreted by adipose tissue, circulates in direct proportion to body fat stores, enters the brain and regulates food intake and energy expenditure. Deficient leptin neuronal signalling favours weight gain by affecting central homeostatic circuit...

Abstract Leptin plays a major role in the regulation of energy intake and expenditure, triggering effects on several tissues, such as hypothalamic-pituitary-thyroid axis. The reported leptin thyroid are controversial, being mainly explored during imbalance. Therefore, aim this study was to evaluate function rats fed ad libitum distinguishing direct responses from those mediated by leptin-depend...

We have previously shown that (i). leptin and leptin receptor (Ob-R) are expressed in the human endometrium, and (ii). leptin secretion is regulated in blastocyst and endometrial epithelial cell (EEC) co-cultures. Interleukin-1beta (IL-1beta) up-regulates leptin and Ob-R, and both cytokines up-regulate beta3 integrin expression in EEC. In the present investigation we examined the effect of lept...

Background: Leptin, the hormonal product of the obese (ob) gene, circulates in the blood at levels paralleling those of fat reserves and regulates satiety. In cattle, leptin has also been implicated in the control of ovarian function, but its local production in the ovary and role in the control of ovarian function in autocrine/paracrine manner is unknown. The aims of this study were to documen...

Background and Aim: Cessation of ovarian function is a major cause postmenopausal osteoporosis. Ovariectomized rats dogs have been used extensively in osteoporosis models. This study examined the effect Pueraria Radix isoflavone extract not only on Bone Mineral Density (BMD) but also bone strength using formation resorption markers ovariectomized as an model. Methods: The model (OVX) induced by...

BACKGROUND Hemangiomas are the most common benign tumors of infancy. This study evaluated the efficacy of oral propranolol comparing to oral steroids in management of pediatric hemangiomas. METHODS In North India from January 2012 to January 2015, sixty children <6 years old with superficial hemangiomas were divided into 2 groups; oral propranolol vs. oral prednisolone. All participants we...

It is well documented that the hormone leptin regulates many central functions and that hippocampal CA1 pyramidal neurons are a key target for leptin action. Indeed, leptin modulates excitatory synaptic transmission and synaptic plasticity at the Schaffer-collateral input to CA1 neurons. However the impact of leptin on the direct temporoammonic (TA) input to CA1 neurons is not known. Here we sh...

The cloning of mouse obesity genes and their human homologues provides unique opportunities to identify novel cellular targets for therapeutic intervention. The first of these to be cloned, agouti, antagonizes central nervous system melanocortin receptor (MCR) binding, resulting in hyperphagia and an obesity/hyperinsulinemia syndrome. There appears to be significant cross-talk between the agout...

Peroxisome proliferator-activated receptor-gamma coactivator-1 (PGC-1), a cold-induced protein expressed in brown adipose tissue (BAT), plays a role in adaptive thermogenesis by up-regulating uncoupling proteins (UCP). Here, we explore its relationship to the thermogenic actions of leptin, which also up-regulates UCPs. We find that PGC-1 messenger RNA (mRNA) is markedly reduced in BAT of obese ...
