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 ...
in the present study, the effect of e-64 at different concentrations (0.5, 1, 5 and 10 µm) added to (1) the ivm medium on oocyte nuclear maturation and developmental competence of ovine oocytes, and (2) to the ivc medium on embryonic development of ovine embryos were investigated.
the aim of the present study was to determine the in?uence of presence or absence of corpus luteum (cl) on hormonal and metabolites composition of follicular ?uid (ff) harvested from different sized follicles and its relationship with blood serum concentrations in sanjabi ewes. ovaries and blood samples were collected from 60 clinically healthy adult ewes (sanjabi breed) 1–3 years of age in dio...
Introduction: Ghrelin, increases food intake, decreases T3 and T4 concentrations and stimulates insulin release, while leptin reduces food intake and suppresses appetite. Considering the importance of thyroid hormones, ghrelin and leptin in body metabolism, the purpose of this study was to investigate the effect of interactions between ghrelin and leptin (injected via ICV route) and plasma T...
in the present work, a simple and sensitive method was developed for determination of morphine and heroin using gold nanoparticles as resonance rayleigh scattering (rrs) and colorimetric technique’s probe. synthesized gold nanoparticles by sodium citrate reduction method have a negative charge layer on their surfaces because of self-assembled citrate anions on their surface. binding of morphin...
the purpose of this study was to evaluate the probable effects of leptin addition in different levels to the semen extender on sperm quality (motility and motility parameters, viability, sperm membrane integrity, and dna damage). semen specimens were evaluated immediately after leptin addition, equilibration time and after thawing the frozen semen. five healthy buffalo bulls (5 ejaculates from ...
In dairy cattle, the increase in milk yield has been accompanied by a more negative energy balance during early lactation and a decrease in fertility. The 167 amino acid protein product of the ob gene was named leptin (derived from the Greek term ‘leptos’ meaning thin). The leptin hormone, as a 16-kDa protein is synthesized mainly by adipose tissue and is involved in regulation of food intake, ...

the adipokines, leptin and adiponectin, have a prominent role in the pathogenesis of coronary artery disease (cad). the inflammatory enzyme, myeloperoxidase (mpo) also has an important role in the pathogenesis of cad. association of the adipokines with mpo remains to be resolved in patients with cad. in this case-control study, 100 patients with cad and 100 control subjects were appropriately r...
