Vasopressin (AVP) RIA Test
Description:... Arginine vasopressin (AVP), also known as Antidiurectic Hormone (ADH), is synthesized in the
hypothalamus and is transported via exonal flow to the posterior pituitary for storage and eventual release. AVP secretion is regulated by changes in blood ...

Leptin IRMA Test
Description:... state of these individuals may be related to a leptin resistance and an inability of leptin to enter the cerebral spinal fluid to reach sites in the
hypothalamus to regulate appetite. Involvement of a leptin receptor or carrier protein in this kind of regulation has been suggested. Serum leptin levels follow ...

Leptin Soluble Receptor ELISA Test
Description:... signals the brain to counteract weight loss by increasing feed intake and decreasing energy expenditure [3]. Leptin operates at the level of the
hypothalamus and acts via specific receptors to control the expression of the appetite stimulator, neuropeptide Y (NPY). This feedback mechanism provided by ...

ACTH RIA Test
Description:... circulation, where it has a half-life of approximately 20 minutes [1]. ACTH is secreted in response to corticotropin-releasing factor (CRF) from the
hypothalamus [1]. The actions of CRF are augmented by arginine vasopressin. Several other stimulatory and inhibitory factors, including catecholamines and ...

TSH ELISA Test
Description:... transport and resultant thyroid hormone synthesis [2]. TSH secretion is stimulated by thyrotropin-releasing hormone (TRH) which is secreted by the
hypothalamus and is regulated at both the pituitary and hypothalamic levels by thyroid hormones. Low levels of thyroid hormones lead to increased TSH secretion ...

FSH ELISA Test
Description:... In the late follicular phase of the menstrual cycle, increased levels of estrogen secreted by the mature follicle exert positive feedback on the
hypothalamus and pituitary, resulting in a GnRH surge and a peak of LH and FSH release [2,3]. This surge is followed by rupture of the graafian follicle and ...
