Thyroid hormones are essential for vertebrate development. There is a characteristic rise in thyroid hormone levels in blood during critical periods of thyroid hormone-regulated development. Thyroid hormones are lipophilic compounds, which readily partition from an aqueous environment into a lipid environment. Thyroid hormone distributor proteins are required to ensure adequate distribution of ...

diabetes is a metabolic disorder which affects whole body systems including reproductive system. diabetes is also a contributing factor to infertility. metformin is one of the most common drugs to control hyperglycemia. in this study, 36 adult sprague-dawley female rats (170-210 g) were divided into 3 groups (control, diabetic and diabetic-treated by metformin). in second and third groups, diab...

Background and Aims: Thyroid hormones have an important role in metabolism and regulation of the red blood cells (RBCs). Thyroid dysfunction induces various effects on blood cells such as anemia through reducing the oxygen metabolism. For the first time, we aimed to determine the effects of severity activation of hypothyroidism on RBCs indices in patients with hypothyroidism. Materials and Met...

Coastal waters in northern part of Hormuz Strait receive large inputs of anthropogenic pollutants. This study was conducted to determine the effects of environmental contaminants on plasma enzymes, thyroid hormones and biochemical blood parameters of Periophthalmus argentilineatus to monitor marine pollution from northern part of Hormuz strait. For this purpose, a total of 90 specimens were col...

The mechanisms involved in cardiovasular changes during human pregnancy and the complicated aetiology of gestational hypertension are unclear. Reproductive hormones have known effects on the cardiovascular system in the non-pregnant state and in animal systems, but their effects in human pregnancy are uncertain. In this study of pregnant women, the effects of serum concentrations of relaxin, pr...

The brain controls the activities of body, including food digestion, drinking, sleep cycles, temperature, blood pressure, and more. These functions are essential to keep body in homeostasis, which is state being steady balanced. To control talks with help chemical messengers called hormones. Hormones travel through stream from back. However, order protect delicate cells unwanted intrusions, ves...

Hormones are involved in a plethora of processes including development and growth, metabolism, mood, and immune responses. These essential functions are dependent on the ability of the hormone to access its target tissue. In the case of endocrine hormones that are transported through the blood, this often means that the endothelium must be crossed. Many studies have shown that the concentration...
