Numerous contributions regarding the pathogenesis of ascites and edema have been made since Starling's first description of the balance between serum and tissue hydrostatic and osmotic forces. The original concept (1) proposed that, at equilibrium, serum protein osmotic pressure minus tissue fluid osmotic pressure equals capillary hydrostatic pressure minus tissue hydrostatic pressure. Direct a...

Osmotic pressure maintained by liver or kidney tissue measured by its water equilibrium with solutions of sodium chloride remains unchanged from 5 minutes up to 1(1/2) hours following removal of the tissue from the body. Then with autolytic increase of molecular concentration within the cytoplasm of cells it reaches a higher level. Osmotic pressure maintained by pancreas or submaxillary gland, ...

We discuss the stability of icosadeltahedral shells subjected to a uniform external load in the form of an isotropic pressure. We demonstrate that there exists a universal critical buckling pressure scaling form that defines a locus of buckling instabilities. The parameter that uniquely determines this scaling form is shown to be the Föppl-von Karman number of nonpressurized shells. Numerical r...

Macromolecules such as hemoglobin exert both kinetic and matrix effects on osmotic pressure. The kinetic osmotic pressure of sickle-cell hemoglobin is lost upon deoxygenation at physiological erythrocyte concentrations. The non-kinetic or matrix component of osmotic pressure remains relatively unchanged. Loss of thermal-osmotic activity during deoxygenation occurs throughout a hemoglobin concen...

A laboratory-scale submerged anaerobic membrane bioreactor (SAnMBR) treating sewage was used to investigate the membrane fouling mechanism. Characterization of cake layer formed on membrane surface showed that cake layer was hydrated, rich of extracellular polymeric substances (EPS) and negative charged with the charge density of 0.21-0.46 meq/kg MLSS. Detailed analysis revealed a new membrane ...

While the relationship between intraocular pressure and plasma osmolarity has been investigated during hemodialysis, no research has been published concerning the relationship between intraocular pressure and plasma colloid osmotic pressure during hemodialysis. We describe a patient with neovascular glaucoma who demonstrated a marked decrease in intraocular pressure during hemodialysis. The pat...
