objective(s): leptin is a hormone secreted by adipose tissue and is involved not only in the regulation of feeding and energy expenditure, but also its role in memory enhancement has been demonstrated as well. the partial transfer of leptin across the blood-brain barrier in obese individuals causes leptin resistance and prevents leptin reaching brain. on the other hand, studies have shown that ...
Experiments in ob/ob female mice demonstrated that leptin injections not only reduced weight and fat mass, but also restored fertility and partial lactation. To explore factors regulating ob gene expression in reproductive women, we measured serum leptin, body fat, energy expenditure, and milk production in 65 women at 36 weeks of gestation, and at 3 and 6 months postpartum. Serum leptin was me...
Leptin is a small peptide hormone that is mainly produced in adipose tissues. Leptin plays animportant role in regulating appetite and energy expenditure and may be involved in modulatingbone mineralization. This study was designed to test the association of serum leptin kidneyfunction in renal transplant recipients. We studied 72 kidney transplanted recipients. In thisstudy a significant diffe...
OBJECTIVES Aim of the present study was to investigate serum concentration of leptin and its association with values of body mass index (BMI), C-reactive protein (CRP), and erythrocyte sedimentation rate (ESR) in hemodialysis (HD) patients. METHODS This cross-sectional study included 60 HD patients (34 male, 26 female) and 30 age- and sex-matched (4 males, 26 females) apparently healthy subje...
Leptin, secreted from fat cells, functions as a lipostat mechanism through modulation of satiety signals. The role of leptin in humans has been only partly revealed. However, obese patients have markedly elevated levels of this hormone, and in both normal-weight and obese subjects there is a direct correlation between serum leptin levels and the percentage of body fat. The aim of the present st...
BACKGROUND Leptin, a hormone present in breast milk, is involved in energy regulation and metabolism. The objectives of this study were to assess leptin concentrations in breast milk during the first 180 days postpartum, and to determine the relationship between the concentrations of milk leptin and circulating hormone levels in lactating women. METHODS Between April 2005 and January 2006, bl...
OBJECTIVE To examine the relationship between serum leptin levels and suppression of CD4 count in HIV-infected individuals with highly active antiretroviral therapy (HAART). SUBJECTS AND METHODS Thirty seropositive HIV male patients selected from the Infectious Disease Hospital were classified into two groups according to their immunological and virological response to HAART. The first group ...
We compared serum leptin responses during and after laparoscopic and open cholecystectomy, and assessed their correlation with the responses of inflammatory cytokines. Serum levels of leptin, interleukin-1alpha (IL-1alpha), interleukin-6 (IL-6) and tumor necrosis factor-alpha (TNF-alpha) were measured by an enzyme-linked immunoassay in 31 patients who underwent laparoscopic cholecystectomy and ...
OBJECTIVE Leptin is an adipocyte-derived hormone and has shown positive correlation with obesity and metabolic syndrome (MetS) in many studies. However, there are few studies investigating this relation in elderly people. Therefore, we aimed to investigate the correlation between the fasting serum leptin level and MetS among older Taiwanese. MATERIALS AND METHODS The fasting serum leptin leve...
Introduction: Recent investigations have shown that leptin is cleared principally by the kidney. Objectives: To examine whether and how in patients on hemodialysis the level of C-reactive protein level correlate with serum leptin. Patients and Methods: The total patients were 36. The mean patients' age were 46 (16) years. The median length of the time patients were on hemodialysis were 19 month...
