Biological membranes composed of lipids and proteins are central for the function all cells individual components, such as proteins, that readily studied by a range structural approaches, including x-ray crystallography cryo-electron microscopy. However, study complex molecular mixtures within biological membrane structure dynamics requires techniques can nanometer thick bilayers in an aqueous ...

one of the most important concerns in tehran municipal landfill is the production of leachate and its potential for water resources pollution, this study was undertaken to examine feasibility of biological and physico/chemical treating of high-strength landfill leachate that was collected from tehran municipal landfill. average cod of the leachate in aerobic submerged membrane bioreactor is 68...

background: considering the toxic effects of heavy metals and microbial pathogens in industrial wastewaters, it is necessary to treat metal and microbial contaminated wastewater prior to disposal in the environment. the purpose of this study is to assess the removal of heavy metals pollution and microbial contamination from a mixture of municipal and industrial wastewater using membrane bioreac...

Abstract Cell membrane vesicles, as delivery carriers of drugs or biological agents in vivo, are an important therapeutic mode the study disease treatment. Tumor membrane-derived vesicles have been widely used tumor therapy because their good enrichment effect. The most common method is surface nanoparticles coated with cell membrane, which can effectively prolong circulation time particles blo...
