Downstream of Ras, the serine/threonine kinase, B-raf, has recently been reported to be mutated, among other carcinomas, in a substantial subset of primary melanomas with a preponderance of the oncogenic V599E transition. As the risk of melanoma is enhanced by intermittent ultraviolet (UV) exposure but is less with chronic UV exposure, we here studied B-raf kinase domain (exon 15) mutations in ...
OBJECTIVE To help physicians become more comfortable assessing the fitness to drive of patients with complex cardiac and cognitive conditions. QUALITY OF EVIDENCE The approach described is based on the authors' clinical practices, recommendations from the Third Canadian Consensus Conference on Diagnosis and Treatment of Dementia, and guidelines from the 2003 Canadian Cardiovascular Society Co...
Studies were performed on 20 male adult rats to investigate the effects of chronic intermittent infusion of lipid and physiological emulsifier into the distal small intestine on stomach to caecum transit time (SCTT) of the head of a test meal. SCTT was measured using environmental hydrogen analysis. Ileal lipid infusion normally delays gastric emptying and small intestinal transit (p < 0.001), ...
Psychological stress is a risk factor for atherosclerosis, yet the pathophysiological mechanisms involved remain elusive. The transfer of cholesterol from macrophage foam cells to liver and feces (the macrophage-specific reverse cholesterol transport, m-RCT) is an important antiatherogenic pathway. Because exposure of mice to physical restraint, a model of psychological stress, increases serum ...
