Composition and Gene Expression of the cag Pathogenicity Island in Helicobacter pylori Strains Isolated from Gastric Carcinoma and Gastritis Patients in Costa Rica
(Infection Immunity 69 (3) 1902-1908, 2001-03)
The composition and in vitro expression of the cag pathogenicity island genes in a group of Helicobacter pylori strains obtained from patients suffering from chronic gastritis-associated dyspepsia (n = 26) or gastric ...
The cag Pathogenicity Island of Helicobacter pylori is Disrupted in the Majority of Patient Isolates from Different Human Populations
(Journal of Clinical Microbiology, 42(11), p. 5302-5308, 2004-11)
The cag pathogenicity island (cag-PAI) is one of the major virulence determinants of Helicobacter pylori. The chromosomal integrity of this island or the lack thereof is speculated to play an important role in the progress ...
X-ray screening seems to reduce gastric cancer mortality by half in a community-controlled trial in Costa Rica
(British Journal of Cancer 97, p. 837 – 843, 2007-10-02)
X-ray screening of gastric cancer is broadly used in Japan, although no controlled trial has proved its effectiveness. This study evaluates the impact of an X-ray screening demonstrative intervention to reduce gastric ...
