Concordance between rats and mice in bioassays for carcinogenesis.

According to current policy, chemicals are evaluated for possible cancer risk to humans at low dose by testing in bioassays in which high doses of the chemical are given to rodents. Thus, risk is extrapolated from high dose in rodents to low dose in humans. The accuracy of these extrapolations is generally unverifiable because data on humans are limited. However, it is feasible to examine the a...

The Relationship between Helicobacter Pylori and Extra-Gastrointestinal Infections

Helicobacter pylori (H. pylori) has been identified as the major agent in human gastric cancer by the International Agency for Research on Cancer (IARC). Infection caused by H. pylori plays a leading role in many disorders including duodenal and gastric ulcer, chronic gastritis, lymphoid tissue lymphoma, and gastric adenocarcinoma. In addition, growing evidence suggests that H. pylori interfere...
