High cut‐off membraneMyoglobinAcute renal failure is a major complication of rhabdomyolysis. New membranes for hemodialysis have been developed with a high cut-off pore size allowing efficient removal of myoglobin. We report on six patients treated by hemodiafiltration with a high cut-off membrane ...
as well as for conventional high-flux and high cut-off membranes for comparison. The differences between the MCO membranes are evident from 1 to 4, showing increased MWRO and MWCO values, which indicate increased permeability.
The main characteristics of the membranes obtained (permeability coefficients and molecular weight cut-off) match those typical to ultrafiltration membranes. It was found that the developed asymmetric ultrafiltration polyimide membranes have excellent thermal and chemical resistance. The membranes retain ...
Therefore, GO membranes with high water permeance and good molecular weight cut-off can be realized by engineering their porosity and pore size. Generally, there are three main transport pathways for water and ion species through GO membranes: inter-edges spaces, intrinsic/created structural defects...
Membranes were blocked for 1 h in 5% milk in Tris-buffered saline (TBS)-Tween and then hybridized using the corresponding primary antibodies in 5% BSA TBS-Tween. All primary antibodies were used at dilution 1:1000. Mouse and rabbit horseradish peroxidase (HRP)-conjugated secondary antibodies ...
(Image J). After completion of the western blot, all membranes were stained with Amido black or ponceau18,23,31, and the densitometry of each lane was calculated using Quantity One Software (Biorad, Hercules, CA) allowing for total protein normalization. This method of normalization has been ...
In this study, feed concentrations of up to 10,000 ppm of bovine serum albumin (BSA) were investigated with three polymeric membranes, two of which had the same molecular weight cut-off (namely, PES100 and PSF100), and two were of the same membrane material (namely, PES100 and PES10)...
The membranes were blocked with 5% bovine serum albumin (BSA) for 1 h at room temperature and incubated with the following primary antibodies overnight at 4°C: rabbit anti-Occludin (A2601; ABclonal; 1:1,000), rabbit anti-Claudin 1 (A2196; ABclonal; 1:1,000), rabbit anti-ZO-1 (...
(TrOCs), including pharmaceuticals, pesticides, hormones and antibiotics1,2. Therefore, high-retention membranes such as nanofiltration (NF), reverse osmosis (RO), forward osmosis (FO), and membrane distillation (MD) have been introduced in biological treatment to achieve high removal of TrOCs. ...
(containing only solids smaller than the cut-off size) passing through the membrane. The cut-off size depends on the pore size distribution within the membrane. In all cases, membranes need to maximise both selectivity (i.e. the ability to remove as much impurity material as possible) and ...
