Introduction:Obesity is one of the most serious challenges of our era, with significant health consequences and high economic burden for health systems. Therefore, many countries have developed political agendas to cope with this ever-rising challenge. Along with chemical medications that are developed to manage obesity, researchers have focused on some natural ingredients and herbal extracts w...

Background and Aim. Leptin has two forms in the circulation: free and bound forms. The soluble leptin receptor (sOB-R) circulates in the blood and can bind to leptin. The aim of this study is to assess the concentrations of the leptin and the sOB-R in PCOS and its relation to adiposity, insulin resistance, and androgens. Methods. A cross-sectional study included 78 female students aged 17-25 ye...

The aim of this study was to investigate if anthropometric parameters are associated with both leptin and soluble leptin receptor (sLEPR) levels in newborns and their mothers. This cross-sectional study was performed in 118 mother-newborn pairs. The venous blood sample of mothers was taken before delivery and immediately after delivery an umbilical cord blood sample was collected. Levels of lep...

Background: Leptin is an adipokine that circulates in a free form and bound to a soluble leptin receptor. Patients with polycystic ovary syndrome have increased insulin resistance and high incidence of obesity. Objective: This study was carried out to evaluate levels of leptin and free leptin in women with polycystic ovarian syndrome (PCOS) and note any relationships with insulin resistance and...

OBJECTIVES Subnormal leptin levels in low birth weight infants may allow for catch-up growth during infancy. Scant data are available that relate growth with circulating leptin during normal infancy in primates. The current study objective was to examine the association between serum leptin, its soluble receptor (sOB-R), testosterone and IGF-I concentrations, and body weight during infancy in m...

aim : leptin is a 16 kda polypeptide hormone which secreted by adipose tissue and has an important role in energy balance, insulin pathway and inflammation, because of that it may play an important role in colorectal cancer (crc). leptin exerts its effect through the leptin receptor (lepr) a member of the class i cytokine receptor family. background : we have investigated whether glutamine to a...

BACKGROUND The aim of this study was to investigate the relationships between the serum levels of soluble leptin receptor (SLEPR), and total, free and bound leptin, and the change in the serum SLEPR level during an IVF cycle. METHODS Serum concentrations of leptin and SLEPR were measured in 50 Japanese women of reproductive age, and 20 patients participating in an IVF programme. The total lep...
