Mechanisms of Small Intestinal Adaptation

Digestive Diseases, 2008
Luminal nutrition, hormonal factors and pancreatobiliary secretions are probably the major mediators of small intestinal adaptation. Their actions, as discussed in this paper, are likely to be interrelated. Direct local enterotrophic effects cannot account for all the actions of luminal nutrients.

Intestinal adaptation to protein deficiency

Cell Biology International Reports, 1982
Abstract Feeding weanling rats a protein-deficient but energetically adequate diet leads to a marked change in intestinal architecture with no obvious change in the overall capacity to absorb amino acids ( Syme, 1982 ). Using autoradiographic localization of tritiated amino acids within enterocytes ( King et al., 1981 ), one can show that valine ...

Clinical Models of Intestinal Adaptation

Annals of the New York Academy of Sciences, 1998
ABSTRACT: Mucosal adaptation of the small intestine is morphologically restricted to only three different patterns, namely, atrophy, hyperplasia, and hyperregeneration. The hyperplastic mucosa in the experimental short bowel syndrome exhibits unchanged epithelial barrier properties and a differential functional adaptation with a 150% increase in Na ...

Towards Understanding the Process of Intestinal Adaptation

Digestive Diseases, 2008
When bowel is lost due to disease or surgery, the residual bowel increases its functional capacity in order to compensate for the loss of absorptive capacity. The success and extent of this adaptive process is critical to recovery. This article reviews the current understanding of the intestinal adaptation.

Morphological Adaptations of Intestinal Helminths

The Journal of Parasitology, 1991
Nematodes, trematodes, cestodes, and acanthocephalans each have become adapted in different ways to the microenvironment of the vertebrate intestine. Life in this specialized habitat affords parasites a reliable source of nutrients, a relatively homeostatic environment, and protection from predators but, in exchange for these advantages, presents the ...

Intestinal Adaptation Symposium

Canadian Journal of Physiology and Pharmacology, 1990
The absorptive function of the intestinal tract depends on the intact villous and crypt structures which are the functional units of the small intestine. The villi increase the absorptive surface area of the intestine 7to 14-fold. The epithelial cells covering the surface of the villus are mature cells that are covered with a microvillous membrane ...

Mechanisms of intestinal adaptation

Pediatric Surgery International, 1988
The control of intestinal adaptation is complex and involves different mechanisms at different sites. The principal basic stimuli to adaptive growth are the presence of food in the gut lumen, endogenous secretions, and circulating hormones and peptides. Lesser factors include neural and vascular influences.

Predicting Intestinal Adaptation in Pediatric Intestinal Failure

Annals of Surgery, 2019
Objective: The primary goal in intestinal failure (IF) is adaptation and enteral autonomy (EA). Our goals were to determine the proportion of patients treated for IF by an established intestinal rehabilitation program who achieved EA and to assess the predictors of EA.

Nutrient absorption and intestinal adaptation with ageing

Best Practice & Research Clinical Gastroenterology, 2002
Malabsorption of carbohydrates, lipids, amino acids, minerals and vitamins has been described in the elderly. The ability of the intestine to adapt may be impaired in the elderly and this may lead to further malnutrition. Dietary manipulation may prove to be useful to enhance the needed intestinal absorption with ageing.

Overview of Intestinal Adaptation and its Stimulation

European Journal of Pediatric Surgery, 1999
Total parenteral nutrition (TPN) can be life-saving for many patients with short-bowel syndrome (SBS). However, chronic TPN administration is associated with nutritional deficiencies, septic complications, high health care costs, and life-threatening organ failure.
