The effects of five UICC asbestos samples, titanium dioxide, and quartz on the bovine red cell membrane have been studied in erythrocyte ghosts by the spin labelling technique. Analysis of the electron paramagnetic resonance (EPR) spectra of two sulphydryl reactive spin labels and one fatty acid spin label in red cell ghosts showed modifications in membrane protein after asbestos treatment but ...

Cell migration and spreading involve the coordination of membrane trafficking, actomyosin contraction, and modifications to plasma membrane tension and area. The biochemical or biophysical basis for this coordination is however unknown. In this study, we show that during cell spreading, lamellipodia protrusion flattens plasma membrane folds and blebs and, once the plasma membrane area is deplet...

RESIDUAL GENTAMICIN ON A MILLIPORE MEMBRANE WAS INACTIVATED BY MODIFICATION WITH TWO DIFFERENT ENZYMES: gentamicin adenylyltransferase and 3-N-acetyltransferase. Both modifications allowed the growth of susceptible strains of Escherichia coli and Bacillus subtilis.

Abstract Recent advances in wastewater treatment processes have resulted high removal efficiencies for various hazardous pollutants. Nevertheless, some technologies are more suitable targeting specific contaminants than others. We comprehensively reviewed the recent removing pollutants from industrial through membrane technologies, adsorption, Fenton-based processes, advanced oxidation (AOP), a...

Activating mutations of NRAS are common in acute myeloid leukemia, chronic myelomonocytic leukemia, and myelodysplastic syndrome. Like all RAS proteins, NRAS must undergo a series of posttranslational modifications for differential targeting to distinct membrane subdomains. Although farnesylation is the obligatory first step in post-translational modifications of RAS, to date, successes of ther...

Functional groups on support membranes are important for the preparation of high-performance membrane adsorbers (MAs). In this work, effects different functional adsorption performance MAs were studied through surface modifications such as alkali treatment, oxidation treatment and polydopamine (PDA) deposition. Our experiment results indicate that chemical bonds prone to form between C-F PVDF a...

Serum and membrane proteins are two of the most attractive targets for proteomic analysis. Previous membrane protein studies tend to focus on tissue sample, while membrane protein studies in serum are still limited. In this study, an analysis of membrane proteins in normal human serum was carried out. Nano-liquid chromatography-electrospray ionization mass spectrometry (NanoLC-ESI-MS/MS) and bi...
