Background Experimental evidence suggests that flow-dependent dilatation of conduit arteries
is mediated by nitric oxide (NO) and/or prostacyclin. The present study was designed to …

We have shown previously that preconditioning myocardium with four 5-minute episodes of
ischemia and reperfusion dramatically limited the size of infarcts caused by a subsequent 40-…

This study tests uses and gratifications theory with 1209 college students. The results find that
students’ media use and surveillance needs increase with year in college. Consistent with …

Background— Heart rate reduction (HRR) improves left ventricular (LV) filling, increases
myocardial O 2 supply, and reduces myocardial O 2 consumption, which are all beneficial in …

Background Plasma levels of the vasoconstrictor peptide endothelin (ET) are increased in
chronic heart failure (CHF), and ET levels are a major predictor of mortality in this disease. …

Background Mobile technology is increasingly being used by clinicians to access up-to-date
information for patient care. These offer learning opportunities in the clinical setting for …

Background— Obesity and diabetes mellitus are independently associated with the
development of heart failure. In this study, we determined the respective effects of obesity, insulin …

Background— The lymphatic system regulates interstitial tissue fluid balance, and lymphatic
malfunction causes edema. The heart has an extensive lymphatic network displaying a …

Preconditioning myocardium with brief episodes of ischemia reduces energy demand and
delays cell death during a subsequent ischemic episode. We hypothesized that postischemic …

Bioterrorism is an area of increasing public health concern. The intent of this article is to review
the air cleansing technologies available to protect building occupants from the intentional …
