...e presence of a BRCA founder mutation. The authors conclude that Ashkenazi BRCA founder mutations do not confer a strongly elevated risk of colorectal cancer. Similarly, a family history of breast cancer does not appear to be a strong risk factor for colorectal cancer in this population. In an accompanyin...AGU journal highlights - 6 January 2004

The newly released findings conclude that the circulating endogenous hormone profile is more dependent on exercise mode or intensity than on exercise volume as measured by caloric expenditure. The study also provides evidence that hormone levels and exercise-induced hormone changes are ...Other highlights in the December 17 issue of JNCI

More important, if BK channels mediate alcohol effects, they write, then the "near-ubiquitous" presence of BK channels in mammals may explain the varied ef...Governing commons still a struggle, but fight not without hope, according to new report

The authors conclude that the challenge is for humans "to develop and deploy understanding of large-scale commons governance quickly enough to avoid the large-scale tragedies that will otherwise ensue."

...) on the reduction of food intake. The researchers conclude that CCK's suppression of food intake is enhanced when the stomach is distended. Background CCK is a hormone released when digested fats and proteins are present, and reduces food intake. CCK stimulates enzyme secretion in the pancreas.
