The incidence and significance of the development of ventricular arrhythmias during insertion and removal of pulmonary artery monitoring catheters were determined in stable postcardiac surgical patients. Insertion of 173 (69 percent) of 250 catheters was associated with ventricular arrhythmias and removal in 158 (63 percent) of these catheters (p greater than 0.05). All arrhythmias resolved spo...

PURPOSE Humans can reduce inorganic nitrate (NO(3)(-)) to nitrite (NO(2)(-)), nitric oxide (NO), and other bioactive nitrogen oxides. The purpose of this study was to test the hypothesis that a single dose of inorganic nitrate before exercise might enhance the tolerance of endurance athletes to high intensity exercise. METHODS Eleven cyclists (age = 34.3 ± 4.8 yr, VO(2peak) = 65.1 ± 6.2 mL·kg...

Dabigatran etexilate, a double prodrug of dabigatran, is a reversible, competitive, direct thrombin inhibitor that has been approved for use in many countries. A recent guideline from the European Medicines Agency on drug-drug interactions proposed dabigatran etexilate as a sensitive in vivo and in vitro probe substrate for intestinal P-glycoprotein (P-gp) inhibition. We therefore performed a s...

BACKGROUND The objective was to determine secular trends in unintentional fall-related hospitalizations in people aged 65 years and older in the United States. MATERIALS Data were obtained from a nationally representative sample of emergency department visits from January 1, 2001, to December 31, 2008, available through the National Electronic Injury Surveillance System-All Injury Program. Th...

Mice were unilaterally irradiated in either a fission neutron or gamma ray field at various dose rates. Jejunal crypt stem cell survival was analyzed by the multitarget single-hit survival model, which yielded excellent fitting survival curves. At the 1 percent survival level, gamma rays were found to be 20 percent more effective in destroying cells when delivered in a brief pulse of radiation ...
