A circadian variation in serum calcium, albumin and PTH concentration in normal subjects has been demonstrated. The levels of the three blood constituents were remarkably constant during the day, but striking night and early morning changes occurred. Serum calcium levels were highest at 8:00 p.m. and reached a nadir between 2:00 and 4:00 a.m. Serum albumin levels were parallel to those of serum...

background: polycystic ovarian syndrome (pcos) represent one of the common endocrine disorders which influence around 8% of reproductive women whom usually suffering from obesity and increase cardiovascular risk. serum homocysteine levels are associated with bad impact on endothelial functions and considered as an independent risk factor for cardiovascular disease. objective: the aim was to stu...

conclusions changes in neonatal leptin levels can reflect changes in the body fat tissue and neonatal birth weight and could be effective in predicting weight gain in newborns with mothers who have gestational diabetes and may reduce birth trauma or future complications. results serum leptin levels in the cord blood of mothers with gdm were significantly higher than in normal mothers. there was...

Background. Most patients with metastatic prostate cancer are endocrinologically treated with LHRH agonist, but finally castration-refractory and hormone-refractory cancers occur. Serum testosterone levels get low to "the castration level" by LHRH agonists but may not get low enough against castration-refractory prostate cancer. Methods. As case series, twelve patients suffering from hormone-re...

Introduction: Determination of thyrotropin, total and free thyroxine and triiodothyronine are widely used as diagnostic methods for thyroid function evaluation. There have been numerous reports of interferences in thyroid hormone immunoassays. Herein, a prominent positive interference is reported for a radioimmunoassay kit of total triiodothyronine. Materials and Methods: In this study, a total...

Purpose: The presence of a potential relationship between metabolic diseases and hormones the intestinal flora has recently gained attention. Levels asprosin trimethylamine oxide (TMAO) may be associated with polycystic over syndrome (PCOS), which is disease. present study aims to investigate PCOS serum TMAO levels.
 Materials Methods: This cross-sectional included 30 patients on metformin...

Hypocalcemia is one of the common complications after total thyroidectomy. In these patients, serum parathyroid hormone (PTH), calcium level decreases, and phosphorus increases. The fibroblast growth factor-23 (FGF-23), a phosphaturic hormone, increases in to normalize level. our study, we aimed investigate predictive values PTH, calcium, phosphorus, 1,25-dihydroxy vitamin D (vitamin D), FGF-23...
