Doctors need to be well informed about differences in the presentation of certain diseases in tropical and temperate climates. In this article the characteristics of some gastrointestinal diseases, as they recur in sub-Saharan Africa, are briefly reviewed. Diseases of the stomach--including ulcertaion and cancer--are uncommon in Africa, although duodenal ulcer is common all over the tropics. In...

BACKGROUND Methylentetrahydrofolate reductase plays a central role in converting folate to methyl donor for DNA methylation. Genetic variations in folate metabolism are believed to contribute to the risk of acute lymphoblastic leukemia, colon, esophageal and stomach cancer, as well as cardiovascular and cerebrovascular diseases. MTHFR C677T and A1298C polymorphisms are known to be risk factors ...

Carotenoids are thought to diminish the incidence of certain degenerative diseases, but the mechanisms involved in their intestinal absorption are poorly understood. Our aim was to obtain basic data on the fate of carotenoids in the human stomach and duodenum. Ten healthy men were intragastrically fed three liquid test meals differing only in the vegetable added 3 wk apart and in a random order...

Disease development depends on several factors including the infecting H. pylori strain, environmental and host factors. Another factor that might influence H. pylori colonization...

Chitinase hydrolyzes chitin, which is an N-acetyl-D-glucosamine polymer that is present in a wide range of organisms, including insects, parasites and fungi. Although mammals do not contain any endogenous chitin, humans and mice express two active chitinases, chitotriosidase (Chit1) and acidic mammalian chitinase (AMCase). Because the level of expression of these chitinases is increased in many...
