background: pregnancy and accelerated fetal growth always are related with major metabolic changes and body fat redistribution and adiponectin is one of principle adipocyte hormones, so studying adiponectin changes during pregnancy may reveal some hidden parts of fetal metabolism. the aim of this study was to assess adiponectin and leptin levels in umbili cal cord and maternal serum, their rela...

Leptin is a hormone produced and secreted by adipose tissue. It is a member of adipokine family with a principal role in body weight regulation. It is reported that low brain leptin levels enhance the activity of hypothalamic orexigenic signals promoting feeding and suppressing energy expenditure and vice versa. Moreover, leptin via its three receptors participates in multiple neuroendocrine lo...

In humans, production of the adipocyte-derived peptide leptin has been linked to adiposity, insulin, and insulin sensitivity. We therefore considered that alterations in plasma leptin concentrations could constitute an additional component of a metabolic syndrome of cardiovascular risk. To explore this hypothesis, we employed factor analysis, a multivariate statistical technique that allows red...

We evaluated serum leptin levels in 9 young chronic myeloid leukemia (CML) patients under imatinib therapy during a long-term follow-up. Body mass index (BMI) and fat mass percentage (%FM) were also measured. Leptin was above the normal range in 8 out of 9 patients. In one case the hormone was below the reference value. All subjects showed a normal BMI, but 3 had a small increase of FM%. One pa...

Serum leptin levels reflect the amount of body fat. However, several reports suggest that insulin may also regulate serum leptin levels. This study was aimed at testing whether leptin levels are low in newly diagnosed patients with type 1 diabetes and increase after institution of insulin therapy. Nineteen children with new-onset type 1 diabetes were studied. Serum leptin levels were measured a...

Abstract Background The role of adipokines such as leptin and adiponectin in regulating the immunity has been documented, however data concerning their consequence on multiple sclerosis (MS) Egyptian patients are deficient. aim this study is to demonstrate serum levels MS assess association with disease disability severity. A case–control including 60 subjects (30 30 age, sex body mass index-ma...

We investigated the effects of leptin receptor gene 3'-untranslated region (3'-UTR) polymorphism on clinical and metabolic parameters in 221 young Japanese men aged 21 to 28 years. The polymerase chain reaction-restriction fragment length polymorphism method was used to identify a pentanucleotide (CTTTA) insertion in 3'-UTR of the leptin receptor gene. Body mass index, blood pressure, plasma gl...

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 ...

introduction: leptin, secreted from adipose tissue may have some correlation with coronary artery disease according to some reports in literature. the mean concentration of plasma leptin in patients with normal and abnormal myocardial perfusion imaging (mpi) and relation of leptin levels, independently to abnormality in mpi after correction for body mass index (bmi) was evaluated. methods: as a...
