osteoporosis is a systemic skeletal disease and there is a close relationship between the sympathetic nervous system (sns) and bone metabolism. leptin has been shown to regulate bone formation and bone resorption via the sns. however, the effect of sns on leptin signaling has not been clearly understood. in the present study, we studied the effect of propranolol on ovariectomy-induced osteoporo...

Recently, extensive efforts have been made to understand the rate of energy expenditure and the weight gain associated with atypical antipsychotic treatment, including identification of markers of obesity risk. In recent years, leptin, an adipocyte hormone, has gained significant interest in psychiatric disorders. S100B has been considered as a surrogate marker for astrocyte-specific damage in ...

The CNS melanocortin (MC) system is implicated as a mediator of the central effects of leptin, and reduced activity of the CNS MC system promotes obesity in both rodents and humans. Because activation of CNS MC receptors has direct effects on autonomic outflow and metabolism, we hypothesized that food intake-independent mechanisms contribute to development of obesity induced by pharmacological ...

Background: It seems that in vaginal delivery, serum leptin level increases as a cortisol-dependent factor due to the stress of the embryo. Studies have shown that if the level of serum leptin is low, the risk of chronic metabolic diseases, cardiovascular diseases, hypertension, and obesity in the mother and the baby will increase. Objectives: The aim of this study was to determine the relatio...

The regulation of bone metabolism mediated by leptin is a complex process that is not clearly understood. Recent studies suggest that CART (cocaine-amphetamine related transcript) is a significant neuronal co-factor when combined with leptin. CART deficiency is thought to result in low trabecular bone mass, but since leptin exerts contrasting effects on trabecular and cortical bone it is possib...

leptin is secreted mainly by fat, which is involved in energy metabolism and reproduction. leptin and itsreceptor (ob-r) have been detected in human spermatozoa and testis, thus it can be concluded leptin involves in male physiology. the goal of this study was determination of the presence of leptin receptor mrna in the ram testis, epididymis and spermatozoa by reverse transcription polymerase ...

background: leptin has been implicated in the differentiation and proliferation of hematopoietic cells. leukemia inhibitory factor (lif) may play an important role, along with interleukin-6 (il-6) and granulocyte colony stimulating factor (g- csf), in the regulation of early hematopoietic stem cells. the aim of the study was to evaluate serum level of leptin, lif, and il-6 in myeloid leukemia p...

Leptin is a hormone primarily produced by the adipose tissue in proportion to size of fat stores with primary function control lipid reserves,this study aimed evaluate influence hypothyroidisim on serum levels Leptin,CRP and profile,blood sample was collected from 75 women age ranged between (15-49) years 65 them had while 10 samples were healthy control, The results showed no significant diffi...
