To elucidate the genesis and effect of atrial fibrillation (AF), 102 patients with acute myocardial infarction were studied. Eighteen patients had AF during the first 72 hours in the coronary care unit. The hospital mortality rate was 23%. Discriminant analysis was used to determine the important variables contributing to the genesis of AF and hospital mortality based on the following variables...

BACKGROUND A strong but presently unexplained inverse association between blood pressure and insulin sensitivity has been reported. Microvascular vasodilator capacity may be a common antecedent linking insulin sensitivity to blood pressure. To test this hypothesis, we studied 18 normotensive and glucose-tolerant subjects showing a wide range in insulin sensitivity as assessed with the hyperinsu...

• It is well known that capillary pressure depends to a considerable degree upon venous pressure. Bayliss and Starling pointed out the importance of this reationship in 1894, but few studies have dealt with its quantitative aspects. Krogh et al. found that capillary filtration in the human forearm was influenced greatly by venous pressure, although changes of the latter were quantitatively less...

We examine the dynamics of a miscible displacement in capillary, calculating nonequilibrium capillary pressure moving (and slowly diffusing) meniscus. During displacement, varies with time following stretching and smearing interface. The remains different from zero for long (on diffusion scale), slowing displacement. This is however completely ignored by all theories currently available practic...

In this study, a grain-scale modelling technique has been developed to generate the capillary pressure-saturation curves for swelling granular materials. This model employs only basic granular properties such as particles size distribution, porosity, and the amount of absorbed water for swelling materials. Using this model, both drainage and imbibition curves are directly obtained by pore-scale...
