![]() ![]() The specialty of analytical chemistry applied to assays of physiologically important substances found in blood, urine, tissues, and other biological fluids for the purpose of aiding the physician in making a diagnosis or following therapy. Physiologically, this agent causes relaxation of bronchial smooth muscle, produces vasodilation (except in cerebral vessels), stimulates cardiac muscle, as well as induces diuresis and gastric acid secretion. It also may be a physiologically relevant docking site for calcineurin. (Scientists identify how the exosomes of the parasite responsible for Chagas disease affect heart cells, University of Granada) Production by a cell or aggregation of cells (a gland) of a physiologically active substance and its movement out of the cell or organ in which it is formed.Įxosomes are nanovesicles released by cells that play an important role in transmitting biological components, both physiologically and pathologically. A certain amount of dead space is normally present in every person (this is known as anatomical dead space: see below). This concept can be extended to include factors that cause a dead space effect. (For species that mate for life, bonding behaviors provide advantages, National Science Foundation) Respiratory dead-space is often increased in lung disease. Definitions Simply put, dead space represents the volume of ventilated air that does not participate in gas exchange. Why are physiologically costly behaviors retained in long-term reproductive partnerships? (Genetic Information Processing Pathway, NCI Thesaurus)Ī therapeutic formulation of the primary physiologically active form of endogenous thyroid hormone. Dietary phospholipids also include molecules derived physiologically from this basic structure.Ī sequence of biological or biochemical events that are involved in the conversion of genetic information into physiologically active molecules, such as functional RNA and proteins. ![]()
