background: some studies propose that changes in leptin concentrations (above or under the normal range) result in infertility. therefore, we investigated serum and follicular fluid leptin concentrations in infertile women with polycystic ovary syndrome (pcos). objective: to study serum and follicular fluid leptin concentrations in infertile women with pcos. materials and methods: we conducted ...

background â to investigate any possible relationship between serum leptin level and h. pylori infection in dyspeptic iranian adults. methods a total of 153 dyspeptic patients referring to  firoozgar hospital for esophagogastroduodenoscopy were enrolled in the study. serum leptin level was measured before endoscopy, after overnight fasting. two biopsy specimens were taken from antrum for each p...

background: leptin plays a key role in the regulation of energy expenditure and is known to circulate in both free and bound forms. soluble leptin receptor (sob-r) is a unique circulating form of leptin receptor that can bind to leptin. leptin and leptin receptor have been implicated in processes leading to breast cancer initiation and progression. our study was aimed to investigate the relatio...

Background Beta-thalassemia is the most common hematology disease in human and leptin is one of the hormone that produce by adiposities cells. The purpose of this study was to investigate the relationship between serum leptin level and thyroid hormones in children with major beta-thalassemia. Materials and Methods This descriptive-cross sectional study was performed on 90 children aged 6-16...

background: leptin is a protein product of obesity gene and is synthesized mainly by adipose tissue. objective: the aim of this study was to determine maternal and neonatal serum leptin levels in term preeclamptic and normal pregnancies. materials and methods: this cross sectional study was performed on 37 preeclamptic and 40 normotensive term pregnant women without other disease. serum level o...

Background The aim of this study was to evaluate leptin serum levels in patients with major beta thalassemia which was also associated with their ferritin serum levels. Materials and Methods This case-control study was performed on 90 children -6 months to 16 years old, in Zabol, Amir- al- Momenin Hospital. Patients were divided in two groups and were matched in age and sex. All Children w...

background : leptin and its receptors have been found in the human gastric mucosa.  its secretion by gastric mucosa has generated interest in its probable role in the gastrointestinal tract and pathophysiology of diseases.   objective: to determine any possible correlation between serum leptin level and pathological findings in patients with duodenal ulcer (du).   methods: in a cross-sectional ...
