This may also be called standard range. In contrast, optimal (health) range or therapeutic target is a reference range or limit that is based on concentrations or levels that are associated with optimal health or minimal risk of related complications and diseases. For most substances presented, the optimal levels are the ones normally found in ...
The ACTH test (also called the cosyntropin, tetracosactide, or Synacthen test) is a medical test usually requested and interpreted by endocrinologists to assess the functioning of the adrenal glands' stress response by measuring the adrenal response to adrenocorticotropic hormone (ACTH; corticotropin) or another corticotropic agent such as tetracosactide (cosyntropin, tetracosactrin; Synacthen ...
In the normal situation, ACTH is released from the pituitary gland at the base of the brain. It acts on the adrenal glands to stimulate the production of steroid hormones (glucocorticoids). If the adrenal glands are healthy, a single injection of tetracosactide results in a rise in blood cortisol concentrations in 30 minutes. If the adrenal ...
Due to the dual role of α-MSH in regulating food intake and hair pigmentation, a defect in proopiomelanocortin (POMC) or its cleavage enzyme, prohormone convertase, results in defects in POMC-derived peptides (e.g., ACTH, MSH) and consequently, Adrenocorticotropic hormone deficiency. Furthermore, the phenotype associated with a defect in POMC ...
ACTH influences steroid hormone secretion by both rapid short-term mechanisms that take place within minutes and slower long-term actions. The rapid actions of ACTH include stimulation of cholesterol delivery to the mitochondria where the P450scc enzyme is located. P450scc catalyzes the first step of steroidogenesis that is cleavage of the side ...
Research conducted by Indiana University's Center for Sexual Health showed that using lube makes it 50% easier for both men and women to orgasm. And it makes sense, too: according to Elist, lube ...
Studies also revealed that a transferrin saturation (serum iron concentration ÷ total iron binding capacity) over 60 percent in men and over 50 percent in women identified the presence of an abnormality in iron metabolism (hereditary hemochromatosis, heterozygotes and homozygotes) with approximately 95 percent accuracy.
"Providers are encouraged to consult with their local lab(s) to obtain hormone level reference ranges for both 'male' and 'female' norms, [which can vary,] and then apply the correct range when interpreting results based on the current hormonal sex, rather than the sex of registration."
