leptin, a circulating 16-kd polypeptide consisting of 167 amino acids, appears to be involved in the body weight homeostasis. moreover leptin plays an important role for the reproductive system, early embryogenesis, and fat metabolism during pregnancy and puberty. significant correlations have been found between leptin and sexual hormones, which is a cytokine and has hormonal properties. the ai...

BACKGROUND Pelvic endometriotic lesions are often laden with hemosiderin. In order to investigate the potential source of such iron deposits, we examined whether the seric and erythrocyte fractions of menstrual effluent might influence the occurrence of iron deposition within lesions in a murine model of endometriosis. METHODS Endometriosis was induced in 57 nude mice by intraperitoneal injec...

Oxidation and adipose tissue uptake of dietary fat can be measured by adding fatty acid tracers to meals. These studies were conducted to measure between-study variability of these types of experiments and assess whether dietary fatty acids are handled differently in the follicular vs. luteal phase of the menstrual cycle. Healthy normal-weight men (n = 12) and women (n = 12) participated in the...
