BackgroundPostoperative pericardial adhesion formation is a prominent cause of morbidity and death in cardiovascular surgery, but there still no ideal prevention method, especially redo cases. This study investigated novel antiadhesion trilaminar polymeric film compared with the Gore PRECLUDE Pericardial Membrane (W. L. & Associates, Flagstaff, AZ) negative control.MethodsOur membrane composed ...

Membrane fouling remains an obstacle to wide-spread applications of membrane bioreactors (MBRs) for wastewater treatment and reclamation. Herein, we report a simple method to prepare a composite conductive microfiltration (MF) membrane by introducing a stainless steel mesh into a polymeric MF membrane and to effectively control its fouling by applying an external electric field. Linear sweep vo...

Magnesium and its alloys may potentially be applied as degradable metallic materials in orthopaedic implantations due to their degradability and resemblance to human cortical bone. However, the high corrosion rate and accumulation of hydrogen gas upon degradation hinders its clinical application. In this study, we adopt a new approach to control the corrosion rate by coating a controllable poly...

Poly(amidoamine)s (PAMAMs) incorporated into a cross-linked poly(ethylene glycol) exhibited excellent CO2 separation properties over H2. However, the CO2 permeability should be increased for practical applications. Monoethanolamine (MEA) used as a CO2 determining agent in the current CO2 capture technology at demonstration scale was readily immobilized in poly(vinyl alcohol) (PVA) matrix by sol...

Polymeric filtration membranes could be a cost-effective alternative to cation exchange (CEMs) in electrolysis with contained anolyte and saltwater catholyte because they size selectively hinder salt ion transport between compartments while facilitating proton hydroxide transport. Optimizing membrane performance requires better understanding of properties that impact electrical resistances rete...

The application of organic-inorganic nanocomposite membranes allows for a synergy between the desirable thermal and mechanical properties inorganic materials with reactivity, dielectric properties, durability, flexibility, processability polymeric materials. Proton exchange membrane fuel cells (PEMFCs) suffer from some problems including water content management, carbon monoxide poisoning, hydr...

• Charged polymeric membranes are characterized by transmembrane streaming potential. Polymeric membrane structure can be affected a pressure application. Sequential difference doesn´t affects surface charge. hydraulic permeability. The effect of on the electrokinetic properties different charged is analysed. Electrokinetic characterization involve application increasing or decreasing differenc...

A polarized cell, to maintain distinct basolateral and apical membrane domains, must tightly regulate vesicular traffic terminating at either membrane domain. In this study we have examined the extent to which microtubules regulate such traffic in polarized cells. Using the polymeric immunoglobulin receptor expressed in polarized MDCK cells, we have examined the effects of nocodazole, a microtu...

As a model system to study protein traffic in polarized epithelial cells, we have used the polymeric immunoglobulin receptor. This receptor travels first to the basolateral surface, where it can bind polymeric IgA or IgM. The receptor is then endocytosed and delivered to endosomes. The receptor is sorted into transcytotic vesicles, which are exocytosed at the apical surface. The 103-amino acid ...
