Micronutrients and Infection
Steve Bunk | Apr 16, 2000 | 6 min read
Courtesy Pacific Northwest National Laboratory Just how important are vitamins and minerals in influencing resistance to infectious diseases? Some of the best current answers to that question will be offered in a supplement to the Journal of Infectious Diseases appearing later this year. The special publication, stemming from a 1999 workshop organized by the National Institute of Allergy and Infectious Diseases, attests that the field is rife with research activity nowadays. Micronutrients such

By feeding female agouti (Avy) mice methyl-rich supplements such as folic acid and vitamin B12, Randy Jirtle and Robert Waterland reduced agouti gene expression in their offspring. This change, caused by direct methylation of a transp

More than 80 percent of the planet's living organisms exist only in aquatic ecosystems. Some may harbor secrets to human origins, and clues, treatments--perhaps even cures--for human disease. Some are critical bioindicators that portend the health of the biosphere. Yet, overall, scientists know little about the biochemical processes of these life forms. The vast, rich knowledge within the oceans and freshwater systems on Earth remains virtually untapped, because in the world of biological resear
