GROSS, JOSEPH F., MARCOS INTAGLIETTA, AND BENJAMIN W. ZWEIFACH. Network model of pulsatile lzemodynamics in the microcirculation of the rabbit omentum. Am. J. Physiol. 226(5) : 1117-l 123. 1974.-Pulsatile pressure and red cell velocities were measured throughout the microvasculature of the rabbit omentum as a function of the order of branching. The data were analyzed in terms of a network model...

Numbers of patients undergoing coronary angiography and angioplasty procedures have increased in England due to targets within the National Service Framework for Coronary Heart Disease. Little evidence is available regarding optimal bed-rest duration for patients post-femoral arterial sheath removal following these procedures. Through literature review and clinical benchmarking, we aimed to ide...

CONTEXT It is not yet clear whether the diurnal variation in testosterone is regulated by circadian or homeostatic (sleep) influences. OBJECTIVE The present study tested whether testosterone is driven by a circadian-independent sleep effect by shifting sleep acutely to daytime in a 24-h sampling regiment. DESIGN, SETTING, AND PARTICIPANTS In the sleep laboratory, seven healthy young men (ag...

natal bed rest may actually have a deleterious effect upon fetal growth and well-being and that until this basic problem is settled it is not possible to say whether the better results obtained by Dr. Varma and Professor Curzen in their decompressed patients are more likely to have been effected by the dcompression itself or by the lesser amount of enforced bed rest to which they were subjected...

A method is described which makes possible the direct microscopic observation of the living retinal microcirculation in the relatively intact globe of animals at magnifications up to ~xl,000. Observations have been made on acute preparations and repeated after intervals as long as six weeks. Observations have been documented in photomicrographs and cinephotographs. Under the conditions of the e...

An initial management of bed rest and hydration is performed routinely. In case of persistent bleeding, definite diagnosis is usually made by angiography, and selective embolization can be performed within the same angiography session as a definite treatment. Open exploration and partial or total nephrectomy are rarely required. We report a case of delayed renal bleeding following stab wound wh...

Turbidity currents in the ocean and lakes are driven by suspended sediment. The vertical profiles of velocity and excess density are shaped by interaction between the current and bed as well as between the current and the ambient water. This paper presents 48 series of experiments in which saline gravity currents flow through a laboratory sinuous flume. flume contains three successive bends wit...

background and objectives: hospital is the largest and most costly operating unit of healthcare system. provision of optimal care requires that hospital administrators identify hospital performance based on relevant indicators. this study used the pabon lasso analysis to assess the performance of hospitals and identify strategies towards an improved hospital performance.   methods: this cross-s...
