A DOUBLE-LUMEN flotation catheter* is now used regularly in myocardial infarction research units to obtain right heart pressures in acutely ill patients. It has proven a safe and reliable method of obtaining right heart pressures without fluoroscopy. The technique is simple: A 5-French double-lumen catheter with a small inflatable rubber balloon just proximal to the tip is inserted into a perip...
The pathogenesis of encephalomyocarditis (EMC) due to the EMC virus (EMCV) was studied in 24 piglets oro-nasally infected with the field isolate B279/95. Two pigs were kept as negative controls and were euthanised at hour 0. The remaining 24 were euthanised every 6 h up to 78-h post infection (hpi). Virus isolation, histological examination and EMCV immunodetection were performed on the spleen,...
BACKGROUND Cardiomyocytes use Ca2+ not only in excitation-contraction coupling but also as a signaling molecule promoting, for example, cardiac hypertrophy. It is largely unclear how Ca2+ triggers signaling in cardiomyocytes in the presence of the rapid and large Ca2+ fluctuations that occur during excitation-contraction coupling. A potential route is store-operated Ca2+ entry, a drug-inducible...
OBJECTIVE This study sought to explore physician organizations' adoption of chronic care guidelines in order entry systems and to investigate the organizational and market-related factors associated with this adoption. DESIGN A quantitative nationwide survey of all primary care medical groups in the United States with 20 or more physicians; data were collected on 1,104 physician organizations...
It is hypothesized that quantitative overload impacts psycho-physiological attributes of data-entry operators, although previous research has focused primarily on different aspects of VDT work, such as working time and environment, work station, keyboards and so forth. The objective of this study was to examine the influence on psycho-physiological responses of time pressure, task demand and th...
Knowledge of the epidemiology of cardiovascular disease (CVD) in hypertensive patients derives primarily from observation of populations composed largely of untreated subjects. Increasingly, however, individuals with elevated blood pressure are treated. An 18-year observational study of 8690 participants in a systematic hypertension control project reveals that cardiovascular events continue to...
