...in their stomachs. Blood is diverted away from the digestive
systemand to the muscles. But food is fuel, and a series of tiny meals eatenregularly to within an hour or two of competition is preferable to one ortwo large meals the night before. A cup of yogurt or a few crackers an hourbefore an event is likely ...
DNA Techniques Allow Scientists To Become Pollution Detectives.
...and by testing its DNA. "E. coli is present in the digestive
tracts of all warm-bloodedanimals," said Mark Tamplin, a professor of home economics atUF/IFAS. "By testing the E. coli (present in fecal matter) forantibiotic resistance and looking at the DNA chains, we can tellif it is human pollution or animal po...
Transgenic Rice Plants Resist Insects, Drought And Salt Damage
...to produce a protein that interferes with insects' digestive
process whenever the plant is wounded by insects. Thus, insects such as the pink stem borer eat less, grow less quickly, and plant damage is reduced to tolerable levels. A barley gene enables rice plants to produce a protein that makes them salt- a...
Tumor Suppressor Gene Located In Liver Cancer Cells
...c enzymes to the lysosomes, a part of the cellular digestive
system that breaks down proteins into simpler compounds. Because the receptor is involved both in switching on a growth inhibitor and inactivating a growth factor, the researchers hypothesized that losing it might well predispose a cell to cancerous ...
Bacterial Toxin Surprises Scientists
...l as to any kind of excreted protein [like digestive
enzymes]." In a paper published in the March 1996 issue of the Journal of General Physiology , the researchers mapped out a rough structure of two conformations of colicin Ia, a toxin produced by some strai...
