José Guiserix, Service de Néphrologie-Dialyse, BP 350 CHSPT, F-97448 Saint-Pierre, La Réunion (France) Dear Sir, Jensen et al. [ 1 ] have recently described a triple-pump dialysis system using a lactate-buffered dialysate. We have extensively been using such a dialysis fluid over the past 5 years, with a double-pump system, in 1,473 hemodialysis sessions in the intensive care unit (n = 585) or ...

introduction: renal failure affects the mechanical and the ventilatory function of the lungs. a few studies have evaluated the ventilatory and pulmonary function in dialysis patients. the present study aimed to compare pulmonary function test (pft) results in patients undergoing hemodialysis (hd) and peritoneal dialysis (pd). materials and methods: we conducted a cross-sectional study on 50  pa...

BACKGROUND Regular monitoring of dialysis grafts is recommended, but the value of dialysis graft blood flow monitoring and venous pressures in predicting subsequent outcomes are controversial. METHODS Over a period of one month, we performed simultaneous flow and venous pressure monitoring in 71 dialysis patients with polytetrafluoroethylene (PTFE) grafts. These patients were prospectively fo...

this work concerns the peristaltic flow of a williamson fluid model in an inclined asymmetric channel under combined effects of heat and mass transfer. the governing nonlinear partial differential equations are simplified under the lubrication approach and then solved analytically and numerically. the analytical results are computed with the help of regular perturbation and the numerical result...

A L-ascorbic acid biosensor based on ascorbate oxidase has been developed. The enzyme was extracted from the mesocarp of cucumber (Cucumis sativus) by using 0.05 mol L phosphate buffer, pH 5.8 containing 0.5 mol L NaCl. After the dialysis versus phosphate buffer 0.05 mol L pH 5.8, the enzyme was immobilized onto nylon net through glutaraldehyde covalent bond. The membrane was coupled to an O 2 ...
