A general approach for enhancing the selectivity of anion-responsive liquid-membrane electrodes is described. The method is based on use of the receptor channel of a flowthrough dialyzer unit as the injection loop in a flow-injection system. An appropriate membrane in the dialyzer prevents ionic interferents from reaching an inselective electrode in the final flow stream The concept is demonstr...

Along with one century of history, research has provided many solutions for hemodialysis (HD) biomaterials, encompassing several generations of copolymers that have found wide application in the development of hollow-fiber dialyzer membranes. Polysulfone-based biomaterials have gained increasing consideration and are now the gold standard in the production of biocompatible hemodialyzers. Howeve...

Of patients with newly diagnosed multiple myeloma, approximately 10% have dialysis-dependent acute renal failure, with cast nephropathy, caused by monoclonal free light chains (FLC). Of these, 80 to 90% require long-term renal replacement therapy. Early treatment by plasma exchange reduces serum FLC concentrations, but randomized, controlled trials have shown no evidence of renal recovery. This...

Dialytic clearance of p-cresyl sulfate (pCS) and other protein-bound toxins is limited by diffusive convective therapies, only a few studies have examined how to improve their removal adsorptive membranes. This study tested the hypothesis that high-flux polymethylmethacrylate (PMMA) dialysis membranes with capacity increase pCS compared polysulfone membranes, in postdilution on-line hemodiafilt...

background several studies have been carried out to evaluate the effects of dialysis on o2 saturation. while the dialysis procedure may lead to hypoxia under different circumstances, there are few studies available on the effects of membrane type on o2 saturation in these patients. objectives this study was to appraise the effects of high and low flux membrane on pulse oxymetery in dialysis pat...

Heat transfer coefficient in nucleate pool boiling near critical heat flux at least one orderhigher than the convectional heat transfer modes. In this paper, an experimental setup isdesigned and fabricated to investigate the mechanism of heat transfer from boiling surface tobulk liquid near critical heat flux. The images of pool boiling near the high heat flux regionreveals that the individual ...

Abstract Background Survival is equivalent between super high-flux hemodialysis (SHF-HD) and online hemodiafiltration (OHDF) with similar albumin leakage. According to the 2013 Japanese dialyzer performance classification, survival on HD optimal when a type II (β 2 -microglobulin clearance ≥ 70 mL/min) used. Here, we investigated whether could be improved by SHF-HD using II-b (sieving coefficie...

BACKGROUND Brain natriuretic peptide (BNP), N-terminal-proBNP (NT-proBNP), and high sensitive cardiac troponin T (TnT) are markers that are elevated in chronic kidney disease and correlate with increased risk of mortality. Data are conflicting on the effect of biomarker levels by hemodialysis (HD).Our aim was to clarify to what extent HD with low-flux (LF) versus high-flux (HF) membranes affect...
