Background: Few studies have investigated maternal leptin concentrations in women with pregnancies complicated by gestational diabetes mellitus (GDM), and these published results are conflicting. We examined the association between plasma leptin concentration and GDM risk.Methods: As a cross-sectional study 741 pregnant women that referred to five university hospital clinics were recruited. The...
Background: Adiponectin and leptin are hormones which are related to body fat tissues and body weight. In pregnant women, conflicting associations have been reported between the role of serum concentrations of adiponectin and leptin with infant birth weight. The aim of this study was to determine the association between maternal and cord blood adiponectin and leptin concentrations with birth w...
Background: Introduction of leptin, a product of the obese gene, recently has led to numerous experiments to better understand body weight and composition function. Based on these findings, leptin is proposed to be an important factor in energy balance and metabolism to influence body weight. In addition, investigators have reported contradictory findings about the influence of physical ex...
background: leptin is a polypeptide hormone secreted by white adipose tissue in proportion to body energy. although the participation of leptin in female reproduction is well established any role in male reproductive function is at best tenuous. objective: the objective of this study was to compare the leptin concentration in human seminal plasma and then the relationships between seminal lepti...
The purpose of this study was to evaluate the probable effects of leptin addition in different levels to the semen extender on sperm quality (motility and motility parameters, viability, sperm membrane integrity, and DNA damage). Semen specimens were evaluated immediately after leptin addition, equilibration time and after thawing the frozen semen. Five healthy buffalo bulls (5 ejaculates from ...
this is an original study on the effect of a polyisobutylene – polydimethylsiloxane (pibpdms) block copolymer modifier used as an interfacial active agent on the dynamics behaviour of single newtonian drops suspended in a polyisobutylene (pib) newtonian matrix. the results were divided in two sections. the first part included the experiments carried out on the non-modified and 2% block cop...
Background: Several studies have recently investigated the role of leptin, the polypeptide hormone secreted primarily by white adipose tissue, in the reproduction of rodents, humans, and domestic animals. Materials and Methods: To investigate the in vitro effect of leptin on buffalo semen quality in equilibrated and frozen thawed semen, five healthy buffalo bulls (5 ejaculates from each bull) w...
Background and Aims: Mucosal-associated invariant T (MAIT) cells are striking lymphocyte population in the blood and their importance in immune responses is growing fast. The current study was conducted to evaluate leptin hormone effects on MAIT cell functions. Materials and Methods: Five healthy male donors in ages of 22-30 years were selected and peripheral blood mononuclear cells (PBMCs) ...
objective(s): leptin exerts various effects on appetite and body weight. disruption of the obesitygene is precedent to fatness. insulin or glucose elevates leptin, but streptozotocin reduces it. however, controversial data exist for the effects of leptin on diabetes and leptin level in each gender. leptin can damage the kidney function but little evidence exists for its hepatic effects. the aim...
Background: Diabetes is a common endocrine disease in human kind. In most type II diabetic patients, obesity and overweight status account as the serious health problems worldwide and variety of endocrine factors well known that have regulatory role in weight balance and body composition including Leptin and IGF-I factor. The aim of this study was to examine the correlation between Leptin and I...
