Articular cartilage injuries are currently one of the world's top health concerns owing to its limited capacity self-renewal, thus raising economic burden in healthcare system. Cell implantation strategies resorting a suitable delivery platform hold great promising approach increase cell retention be further supplied sufficient amount defects. So far, macromolecular engineering toolboxes for de...

There is increasing evidence that surface curvature at a near-cell-scale influences cell behaviour. Epithelial or endothelial cells lining small acinar tubular body lumens, as those of the alveoli blood vessels, experience such highly curved surfaces. In contrast, most commonly used culture substrates for in vitro modelling these human tissue barriers, ion track-etched membranes, offer only fla...

An extended membrane system with a dynamic nested structure, which is integrated the evolution-communication mechanism of cell-like P evolutional symport/antiport rules and active membranes (ECP), evolutionary mechanisms particle swarm optimization (PSO) improved PSO inspired by starling flock behavior (SPSO), named DSPSO-ECP, designed developed to try break application restrictions systems in ...

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...

Zn–air and other metal–air batteries suffer from limited shelf life due to carbonization by CO2 evaporation of water through the cathode. Bioinspired oxygen selective membranes (OSMs) with common similarities lungs alveoli were prepared applied as an passive membrane on cathode batteries, which limit H2O transport while actively supporting O2 flux. The OSMs polycarbonate iron(II) phthalocyanine...

FABP7 nanodomains on glioblastoma neural stem-like cell membranes are greatly reduced when cells cultured in medium supplemented with the omega-3 polyunsaturated fatty acid DHA. Glioblastoma migration is also under these conditions.

Abstract In the present work, a technique to generate pores in Vulcan VCX-72 and VCX-72R commercial coal through Hummers method elaboration of membranes is shown. The product obtained process was cleaned dried, then SEM microscopy which generation observed. Membranes were elaborated using material placed an electrochemical cell set up three electrodes immersed acid solution H2SO4. Autolab® pote...

Metal-organic-framework nanoparticles (MOF NPs) have been increasingly used to encapsulate therapeutic enzymes for delivery. To better interface these MOF NPs with biological systems, researchers coated them natural cell membranes, enabling biomimicking properties suitable innovative biomedical applications. Herein, we report that the enzymatic activity of cell-membrane-coated can be significan...

Native and synthetic membranes can be electrically monitored by creating supported lipid bilayers on top of conducting polymer electrodes. Cell membrane characteristics, e.g. the function transmembrane proteins, are studied in this paper, along with device sensitivity.

In water electrolyzers, polymer electrolyte membranes (PEMs) such as Nafion can accumulate cations stemming from salt impurities in the supply, which leads to severe cell voltage increases. This combined experimental and computational study discusses influence of sodium ion poisoning on ionic conductivity transport a thereon based electrolysis cell. Conductivities aqueous solutions with same am...
