BACKGROUND Patients with decompensated heart failure frequently present with volume overload, which is conventionally treated with diuretics. These drugs have been associated with several adverse effects, including increased mortality, leading some clinicians to propose ultrafiltration as a safe alternative to remove sodium and water. OBJECTIVE The objective of our study was to compare the sa...

OBJECTIVES Ascertainment of adrenal function assessing free rather that total cortisol may be beneficial for the diagnosis of critical illness-related cortisol insufficiency. We hypothesized that centrifugal ultrafiltration would provide timely free cortisol data that highly correlated with the gold standard, but logistically cumbersome, equilibrium dialysis technique when the free cortisol fra...

Plasmids are extra-chromosomal circular double-stranded DNA molecules that can be used to develop recombinant cell lines and to deliver therapeutic genetic material. In gene therapy applications, the in-vivo insertion of the genetic vector results in the production of a desired therapeutic bio-molecule. Gene therapy is of interest in the treatment of a wide range of medical conditions including...

In view of the possibility that the uric acid of the blood might be partly "bound" to protein and partly "free" (Benedict and Behre, 1931) and that this might provide some explanation for the phases of gout, it was decided to investigate various methods of ultrafiltration of the plasma uric acid in gouty and normal individuals. Lambie (1940) reported a case of leukaemia with subsequent developm...

USE OF HIGH-FLUX, preformed ultrafiltration membranes (Diaflo; Amicon Corp., Lexington, Mass.) for separating microand macromolecular constituents of biological fluids has been adequately documented (1-3). A class of these membranes has been formulated into a cone configuration (Centriflo; Amicon Corp.) amenable for use in a laboratory centrifuge. These membranes, highly retentive for the serum...

Fouling due to biofilms composed primarily of microorganisms and extracellular polymeric substances is a significant hindrance to membrane filtration in water treatment. The goal of this work was to use a reactive membrane surface to reduce membrane biofouling by coating a ceramic ultrafiltration membrane with the nanoparticulate photocatalyst, TiO2. 10-Day biofilm growth experiments were condu...

his article describes the use of an ultrafiltration process for the T regeneration of an aqueous alkaline cleaner. Techniques for regeneration of aqueous cleaners are desirable due to the large number of industrial users that have replaced vapor degreasers with aqueous cleaners. Successful regeneration of aqueous cleaners would result in large cost savings for these industrial users who are cur...

This case offers a starting point for a literature review on peritoneal ultrafiltration in refractory heart failure.
