abstract  introduction: during extrinsic coagulation pathway, a complex is developed between factor vii, calcium and tissue factor (a cell membrane lipoprotein that is exposed after cell injury). factor vii needs calcium and vitamin k for its biologic activation. coronary artery disease (cad) can be induced by increased level and activity of the coagulation factors vii, viii and ix. in postmeno...

Basal serum growth hormone, insulin-like growth factor-1 (IGF-1) and somatostatin concentration were measured by standard radioimmunoassay in patients with a diagnosis of rheumatoid arthritis (RA) according to the criteria of the American College of Rheumatology as well as in a group of age-matched normal subjects. RA patients exhibited significantly elevated (age, 45-55 yrs, p less than 0.05; ...

OBJECTIVE The aim of this study was to investigate the effect of serum gonadotropin and total testosterone levels on semen parameters. MATERIALS AND METHODS Three hundred and eighty-two patients that applied to a male infertility polyclinic were included in our study. Serum gonadotropin and total testosterone levels and semen parameters of the patients were analyzed during the first visit to ...

Background Evaluation of anti-mullerian hormone (AMH) cut-off levels in assisted reproductive technology (ART) as predictive factor for individualization of stimulation protocols and to avoid ovarian hyperstimulation syndrome (OHSS). MaterialsAndMethods In a retrospective study, 177 infertile patients were assessed for AMH in serum and follicular fluid (FF) on the day of follicular puncture (FP...

background: chlorpromazine (cpz), an antipsychotic drug, is associated with increased risk of sexual dysfunction through increasing prolactin levels. the current study evaluates the effect of cpz-induced hyperprolactinemia on ovarian follicular growth, gonadotropins, and alteration of ovarian source hormones. materials and methods: in this experimental study, animals were divided into four grou...

The objective of this study was to determine the effect of human chorionic gonadotropin (hCG) on sexual maturation, plasma sex steroids (17β-estradiol, E2 and 17α-hydroxy progesterone (17α OHP)) and thyroid hormones (triiodothyronine, T3 and thyroxin, T4) levels in upstream - migrating Caspian lamprey. During the experiment, 36 fish (24 females and 12 males) in  spring 2013 and 36 fish (24 fema...
