Background: Since the 1910 Flexner Report, medical education continues to undergo curriculum and graduation guideline reform to meet the needs of physicians and patients. Our aims were to (1) assess the quality of musculoskeletal education at our institution's School of Medicine by reporting the results of the Freedman and Bernstein examination among our medical students across all four years of training, and (2) stratify results according to medical school year, educational module, and intended career.
Methods: We surveyed the 460 2009-2010 School of Medicine students via e-mail.
Clinical observations and epidemiological surveys indicated that the prevalence of hypertension and heart diseases is increased in cold regions or during winter. Cold exposure increased NADPH oxidase gp91(phox) protein expression in heart, kidneys, and aorta in rats. The aim of this study was to investigate if RNA interference (RNAi) silencing of gp91(phox) would attenuate cold-induced hypertension and cardiovascular and renal damage.

The effects of the SERCA pump inhibitor cyclopiazonic acid (CPA) were studied in pig coronary artery smooth muscle using two protocols. In protocol A, the SERCA pump was inhibited by adding CPA to cells/tissues in Ca(2+)-containing solution, whereas in protocol B, CPA was added to cells/tissues in Ca(2+)-free solution, followed by reintroduction of extracellular Ca(2+).
