Endocrinology (from endocrine + -ology) is a branch of biology and medicine dealing with the endocrine system, its diseases, and its specific secretions known as hormones.It is also concerned with the integration of developmental events proliferation, growth, and differentiation, and the psychological or behavioral activities of metabolism, growth and development, tissue function, sleep ...
The aromatic/arginine or "ar/R" selectivity filter is a cluster of amino acids that help bind to water molecules and exclude other molecules that may try to enter the pore. It is the mechanism by which the aquaporin is able to selectively bind water molecules and so to allow them through, and to prevent other molecules from entering.
Bogaert's hypothesis argues that "the target of the immune response may be male specific molecules on the surface of male fetal brain cells (e.g., including those in the anterior hypothalamus). Anti-male antibodies might bind to these molecules and thus interfere with their role in normal sexual differentiation, leading some later born males to ...

Amino acid–based hormones (amines and peptide or protein hormones) are water-soluble and act on the surface of target cells via signal transduction pathways; steroid hormones, being lipid-soluble, move through the plasma membranes of target cells to act within their nuclei.
To release active hormones quickly into the circulation, hormone biosynthetic cells may produce and store biologically inactive hormones in the form of pre-or prohormones. These can then be quickly converted into their active hormone form in response to a particular stimulus. [34] Eicosanoids are considered to act as local hormones. They are ...
Some key regulatory hormones for re-absorption include: aldosterone, which stimulates active sodium re-absorption (and water as a result) anti-diuretic hormone, which stimulates passive water re-absorption; Both hormones exert their effects principally on the collecting ducts. Tubular secretion occurs simultaneously during re-absorption of ...
An important feature is the presence of zinc atoms (Zn 2+) on the axis of symmetry, which are surrounded by three water molecules and three histidine residues at position B10. [17] [46] The hexamer is an inactive form with long-term stability, which serves as a way to keep the highly reactive insulin protected, yet readily available.
