Gastrointestinal tract

Helicobacter pylori is a bacterium associated with gastric diseases and disorders of the upper gastrointestinal tract. The gram-negative bacterium Helicobacter pylori is known as a persistent colonizer of the human stomach, and this bacteria is also involved in extra-intestinal diseases. In 1994, the International Agency for Research on Cancer, World Health Organization classified H. pylori as a class 1 carcinogen, the only bacterium given this classification.

Gastrointestinal stromal tumor (GIST) is the most common mesenchymal tumor of the gastrointestinal tract. Stomach is the most affected site. Clinical manifestation is erratic depending on the locations, size, histological type and stage. Confirmed diagnosis of GISTs bases on immunohistochemical study.

A Abatement: Reducing the degree or intensity of, or eliminating, pollution. Abatement Debris: Waste from remediation activities. Absorbed Dose: In exposure assessment, the amount of a substance that penetrates an exposed organism's absorption barriers (e.g.,, skin, lung tissue, gastrointestinal tract) through physical or biological processes. The term is synonymous with internal dose. Absorption Barrier: Any of the exchange sites of the body that permit uptake of various substances at different rates (e.g., skin, lung tissue, and gastrointestinal-tract wall).

This Master by Research project aims to develop the human gas capsule that enables realtime intestinal gas profiling in a low-cost, non-invasive and accurate manner. The safety, viability, reliability and repeatability of the capsule will be evaluated in both laboratorial environments and animal trials that are influenced by dietary effect, heat-stress-induced gut disorder and dietary supplemental therapeutic agent.

ADH1 and ADH4 are the major alcohol dehydrogenases (ADH) in ethanol and retinol oxidation. ADH activity and protein expression were investigated in rat gastrointestinal tissuehomogenates by enzymatic andWesternblot analyses. In addition, sections of adult rat gastrointestinal tract were examined byin situ hybridization and immunohistochem-istry.ADH1andADH4weredetectedalong thewhole tract, changing their localization and relative content as a function of the area studied.

Parkinson’s disease (PD) is a heterogeneous movement disorder character-ized by progressive degeneration of dopamine neurons in substantia nigra. We have previously presented genetic evidence for the possible involvement of alcohol and aldehyde dehydrogenases (ADH; ALDH) by identifying genetic variants in ADH1C and ADH4 that associate with PD.

Okadaic acid (OA) and its analogs, the dinophysistoxins, are potent inhibi-tors of protein phosphatases 1 and 2A. This action is well known to cause diarrhea and gastrointestinal symptons when the toxins reach the digestive tract by ingestion of mollusks. A less well-known effect of these group of toxins is their effect in the cytoskeleton.

Transferrin is the main iron transport protein found in the circulation, and the level of transferrin saturation in the blood is an important indicator of iron status. The peptides amidated gastrin(17) (Gamide) and glycine-extended gastrin(17) (Ggly) are well known for their roles in controlling acid secretion and as growth factors in the gastrointestinal tract.
