Clinicians frequently place post-operative abdominal bandages on horses undergoing laparotomies. Presently, no information exists on the amount of incisional support provided by these bandages. Determination of sub-bandage pressure provides a means of comparing different bandages' ability to support incisions. A randomised, crossover design using 9 healthy horses. Determination of sub-bandage ...

The degree of viscero-abdominal disproportion often makes single-stage reduction difficult in large abdominal wall defects, without risking respiratory or hemodynamic compromise. As a consequence, clinicians have adopted a number of different methods to control these defects. Repair may be in the neonatal period, or later in life. Delayed repairs require ...

Metabolic substrates, such as oxygen and glucose, are rapidly delivered to the cells of large organisms through filtration across microvessels walls. Modelling this important process is complicated by the strong coupling between flow and transport equations, which are linked through the osmotic pressure induced by the colloidal plasma proteins. The ...

Yeast and other walled cells possess high internal turgor pressure that allows them to grow and survive in the environment. This turgor pressure however may oppose the invagination of the plasma membrane needed for endocytosis. Here, we study the effects of turgor pressure on endocytosis in the fission yeast Schizosaccharomyces ...

Icodextrin induces ultrafiltration (UF) during long-dwell exchanges by creating a difference in oncotic pressure between the peritoneal cavity and plasma; however, the mechanisms governing intra-patient and inter-patient variability in UF when icodextrin is used remain largely unexplained. In the present study, we show theoretically that differences in peritoneal residual volume ...

Elastic arteries are significantly prestretched in an axial direction. This property minimises axial deformations during pressure cycle. Ageing-induced changes in arterial biomechanics, among others, are manifested via a marked decrease in the prestretch. Although this fact is well known, little attention has been paid to the effect of decreased prestretch ...

Intra-abdominal hypertension may contribute to a poor outcome. Whether limiting intra-abdominal pressure measurements to preselected at-risk patients allows for sufficient detection of intra-abdominal hypertension is unclear. We aimed to clarify whether expanded intra-abdominal pressure monitoring results in an increased detection rate of intra-abdominal hypertension. Retrospective observational study. General ICU of ...

The determination of the initial pressure at the bubble wall created by a discharge in heptane for micro-gap conditions cannot be determined straightforwardly by modeling the time-oscillations of the bubble. The resolution of the Gilmore equation gives the same solutions beyond 1 μs typically for various sets of initial parameters, making ...

Laplace's law states that within a tubular structure, the transmural pressure required to cause distension is proportional to the wall thickness and surface wall tension, and inversely proportional to its radius. In other words, a structure with a larger radius and low surface tension requires less change in pressure to ...
