...with existing research on the brain and blood chemistry of people with thrill-seeking personalities or certain emotional disorders. Their findings support the estimate that about 40% of the high-thrill temperament is learned and 60% inherited, with telltale differences in such relevant brain chemicals as serotonin, which helps inhibit impulsive behavior and may be in short supply in people with high-wire personalities...
...physicians. It found that men who ate fish five or more times a week had a 40% lower risk of developing colorectal cancer than men who ate it less than once a week. I've long believed that the omega-3 fatty acids in oily fish inhibit the COX-2 enzyme that increases both inflammation and cell proliferation...
...predictable regions, but activity in the anorexics' brains was much more limited. Specifically, the areas involved in visual perception and emotional processing stayed out of play. Because the anorexic patient can scarcely bear to look at herself, Sachdev theorizes, "I think what the brain is trying to do is inhibit the level of processing. It will then distort [the self-image] so what the patient sees is based on preconception rather than on what is really being looked...
Heart muscle cells, or cardiomyocytes, “need a blood supply and oxygen to survive,” said Engel. “FGF1 did not have a great effect on cell proliferation, but we found it was providing a new blood supply. If you just inhibit p38 MAP kinase, you don’t get blood vessels...
...propagation of these malignant cells. Current drug-based treatment works by blocking ERs, thus slowing or stopping tumor growth. The study identified sections of DNA known as control regions, portions of genes pertaining to cell growth and division that bind to the ER. These control regions remotely activate or inhibit the function of the gene. The researchers created a map of all of these regions—several thousand in total. Since genes have multiple control regions, the map indicates that approximately one thousand genes are influenced by the binding of estrogen to the ER, according to a statement released...
