Gravity drainage is the main mechanism which controls the oil recovery from fractured reservoirs in both gas-cap drive and gas injection processes. The liquid bridge formed between two adjacent matrix blocks is responsible for capillary continuity phenomenon. The accurate determination of gas-liquid interface profile of liquid bridge is crucial to predict fracture capillary pressure precisely. ...

BACKGROUND Microvascular rarefaction influences peripheral vascular resistance, perfusion and metabolism by affecting blood pressure and flow pattern. In hypertension microvascular rarefaction has been described in experimental animal studies as well as in capillaroscopy of skin and biopsies of muscle tissue in patients. Retinal circulation mirrors cerebral microcirculation and allows non-invas...

To the editor. The viewpoints put forward by both Point (1) and Counterpoint (4) presenters clearly illustrate that there is a potential for recruitment of capillary reserve in muscle during exercise and in response to insulin administration. The question at hand that arises from the Point/Counterpoint discussion is how capillary blood volume can be increased by muscle contractions or insulin (...

T he effects of hypertension and hypertrophy on the coronary circulation are subjects of increasing investigative interest.1-3 Animal studies have shown that the major conduit arteries are enlarged in pressure-overloaded, hypertrophied ventricles, but this increase falls short of paralleling the extent of hypertrophy.4 This enlargement is accompanied by an increase in the extracellular componen...

A 58-year-old man experienced paradoxic air embolism with passage of air from the systemic venous to the systemic arterial circulation with subsequent stroke and death. No intracardiac shunt was present. Pulmonary fibrosis concomitant with severe pulmonary arterial hypertension appears to have been responsible for the air traversing the pulmonary capillary bed. This unusual outcome of a complic...

This study presents data which indicate that evisceration results in a marked decrease in the rate of disappearance of Evans Blue (T-1824) from the circulation of rabbits. Nephrectomy causes a significant increase in the rate of removal of dye from the blood stream. The possible explanations for these changes are considered, and the objections to the use of dye disappearance as a measure of cap...

Lipoprotein lipase (EC 3.1.1.34) cataly:%es the hydrolysis of plasma triacylglycerols and thereby enables the transfer of triacylglycerol fatty acids from the circulation to various extrahepatic tissues. The enzyme is synthesized in the parenchymal cells of a number of tissues including adipose tissue, heart and mammary gland, and is then secreted and transported to its functional site on the l...
