autolysis

[ȯ′täl·ə·səs]
(geochemistry)
Return of a substance to solution, as of phosphate removed from seawater by plankton and returned when these organisms die and decay.
(pathology)
Self-digestion by body cells following somatic or organ death or ischemic injury.

Autolysis

 

self-digestion of animal, plant, and microorganism tissue. In autolysis the cellular proteins, carbohydrates, and fats break down under the action of hydrolytic enzymes in the cells. In living organisms, autolysis is evident in necrotic centers and in cells of malignant neoplasms. Autolysis occurs in decomposing corpses. In plants autolysis occurs after the death of living cells as a result of low temperature, desiccation, and the action of such poisonous substances as chloroform and toluene, as well as during mechanical tissue disintegration. Autolysis of microbe cells is evident in aging microbe cultures and in microorganisms damaged by physical, chemical, or biological agents. Autolysis also occurs in several industrial processes—for example, in tobacco and tea fermentation and during feed storage.

Pancreatitis is the inflammation and autodigestion of the pancreas in which pancreatic enzymes destroy the tissues of the pancreas itself and leads to inflammation which may be sudden (acute) or ongoing (chronic); in addition, there are also hereditary (genetic) forms of pancreatitis.
When these mechanisms are unable to contain the hyperstimulation of the pancreas, activation of enzymes within the gland leads to its autodigestion and triggers an inflammatory response mediated by interleukins and tumor necrosis factor alpha (TNF-[alpha]).
Spectra were calibrated with trypsin autodigestion Ion peak m/z (842.510, 2211.1046) as internal standards.
Asi, existe un proceso de autodigestion del tejido pancreatico generando un proceso inflamatorio asociado a necrosis tisular.
This process leads to autodigestion and inflammation.
The parameters used were Peak detection algorithm: SNAP (Sort Neaten Assign and Place), S/N threshold: 3.0, quality factor threshold: 50, and internal calibration: trypsin autodigestion peptides (trypsin_[108-115], [MH.sup.+]842.509; trypsin_[58-77], [MH.sup.+]2211.104).
Accumulation of gastric juice and pepsin which involves in the autodigestion of gastric mucosa is implicated in ulcer incidence in PL model (30).
The digestive enzymes elicit autodigestion of pancreatic tissue and a massive inflammatory response (Despins, Kivlahan, & Cox, 2005).
Such a diet not only provides wide spectrum composition of food but also because of its autodigestion characteristics, facilitates a better assimilation in larvae.
La Pancreatitis Aguda (PA) es una enfermedad inflamatoria, causada por la activacion, liberacion intersticial y autodigestion de la glandula por sus propias enzimas (1).
