Regulation of Gastric Acid Secretion
Annual Review of Physiology, 1979The three stimulants of gastric acid secretion likely to have physiological roles in regulation of secretion are acetylcholine, gastrin, and histamine. Acetylcholine is released by vagal and intramucosal reflex stimulation, acting directly on the parietal cell.

REGULATION OF BILE ACID BIOSYNTHESIS
Gastroenterology Clinics of North America, 1999This article provides a review of the pathways through which cholesterol is degraded to bile acids. Regulation of key enzymes in the bile acid biosynthestic pathways is discussed. The important role of these pathways in the maintenance of cholesterol homeostasis and the possible therapeutic implications for the treatment of hypercholesterolemia are ...

Regulation of the acid-base status is an imperative task for maintenance of homeostasis in living animals. Deviations of pH from the predetermined setpoint values may result in reduced metabolic performance as a result of the often pronounced optima in the overall pH/activity relationships of metabolic pathways.

Regulation of fatty acid transport
Current Opinion in Lipidology, 2004The aim of the present review is to summarize recent developments in the area of regulation of fatty acid transport.While controversy still exists regarding the contribution of passive diffusion versus protein-mediated fatty acid transport, both processes are now widely accepted.

Abstract Maintaining a normal pH (7.35–7.45) is necessary for normal physiologic function. Beyond a normal range, widespread organ dysfunction ensues. Normal acid-base physiology is critical for numerous physiologic functions, including enzyme activity, chemical reactions, and transport of oxygen throughout the body.

[Fatty acids regulate NOX activity].
Annales de biologie clinique, 2006NADPH oxidase (NOX) is a multimeric enzyme including a catalytic unit, gp91(phox), and several regulating subunits: p22(phox), p40(phox), p47(phox), p67(phox). This enzyme, also known as flavocytochrome b(588), is responsible for a deliberate production of superoxyde anion (O2*-).

Regulation of bile acid synthesis
Frontiers in Bioscience, 1998Bile acids are important physiological agents required for disposal of cholesterol and absorption of vitamins and fats. Bile acids are synthesized from cholesterol in the liver. Enterohepatic circulation of bile acids is very efficient and plays an important physiological role in lipid absorption and secretion, and regulation of bile acid biosynthesis ...

Receptors regulating acid secretion.
Scandinavian journal of gastroenterology. Supplement, 1991Histamine stimulation of gastric acid secretion has for a long time been known to be mediated by an H2-type receptor located on the parietal cell surface, but the biochemical nature of this receptor has only very recently been elucidated. It is a 70-kDa glycoprotein showing structural analogies with the beta 2-adrenergic receptor and the other seven ...

In this section we will practice the modeling method for endocrine systems explained in Chapter 23. A model for the regulation of gastric acidity in humans will be designed, starting with a process diagram and resulting in a block diagram. The process diagram is gathered from data reported in the literature as are the parameter values used in the model.

Regulation of Bile Acid Synthesis
1974Bile acids formed from cholesterol in the liver are defined as “primary” bile acids. In man, these are chenodeoxycholic acid and cholic acid. Following conjugation with glycine or taurine the bile acids are secreted into the bile and stored in the gallbladder.
