Nitric oxide (nitrogen monoxide) is a molecule and chemical compound with chemical formula of N O. In mammals including humans, nitric oxide is a signaling molecule involved in several physiological and pathological processes. [ 1 ] It is a powerful vasodilator with a half-life of a few seconds in the blood.
Laughter is a pleasant physical reaction and emotion consisting usually of rhythmical, usually audible contractions of the diaphragm and other parts of the respiratory system. It is a response to certain external or internal stimuli. Laughter can rise from such activities as being tickled, [ 1 ] or from humorous stories, imagery, videos or ...
Nathan Bryan is a distinguished industrial researcher and an adjunct assistant professor at the Baylor College of Medicine. [1] With a background in biochemistry, he studied nitric oxide restoration in humans, making contributions to the field. [2] Bryan is the co-founder of HumanN, a firm that develops products designed to elevate nitric oxide ...
Nitric oxide synthases (EC 1.14.13.39) (NOSs) are a family of enzymes catalyzing the production of nitric oxide (NO) from L-arginine. NO is an important cellular signaling molecule. It helps modulate vascular tone , insulin secretion, airway tone, and peristalsis , and is involved in angiogenesis and neural development.
Infobox references. Nitric oxide (nitrogen oxide or nitrogen monoxide[ 1 ]) is a colorless gas with the formula NO. It is one of the principal oxides of nitrogen. Nitric oxide is a free radical: it has an unpaired electron, which is sometimes denoted by a dot in its chemical formula (• N=O or • NO).
Endothelial NOS (eNOS), also known as nitric oxide synthase 3 (NOS3) or constitutive NOS (cNOS), is an enzyme that in humans is encoded by the NOS3 gene located in the 7q35-7q36 region of chromosome 7. [ 5 ] This enzyme is one of three isoforms that synthesize nitric oxide (NO), a small gaseous and lipophilic molecule that participates in ...
UCLA School of Medicine. King Saud University. Louis Joseph Ignarro (born May 31, 1941) is an American pharmacologist. For demonstrating the signaling properties of nitric oxide, he was co-recipient of the 1998 Nobel Prize in Physiology or Medicine with Robert F. Furchgott and Ferid Murad. Currently, he is professor emeritus of pharmacology at ...
A flurry of work in the early 1990s to demonstrate the existence of a retrograde messenger and to determine its identity generated a list of candidates including carbon monoxide, [40] platelet-activating factor, [41] [42] arachidonic acid, [43] and nitric oxide. Nitric oxide has received a great deal of attention in the past, but has recently ...
