Tel.: +86 28 85400453; E-mail addresses: [email protected], zhao Significant progress has been achieved in the last years on the modification of polyethersulfone (PES) membranes. Many articles and reviews have been written on the development in the area of PES membrane modif...

Functioning of proteins efficiently at the solid-liquid interface is critical to not only biological but also modern man-made systems such as ELISA, liposomes and biosensors. Anchoring hydrophilic proteins poses a major challenge in this regard. Lipid modification, N-acyl-S-diacylglyceryl-Cys, providing an N-terminal hydrophobic membrane anchor is a viable solution that bacteria have successful...

A neural stimulation technique that can inhibit neural activity reversibly and directly without genetic modification is valuable for understating complex brain functions and treating brain diseases. Here, we propose a near-infrared (NIR)-activatable nanoplasmonic technique that can inhibit the electrical activity of neurons by utilizing gold nanorods (GNRs) as photothermal transducers on cellul...

Abstract Renal Replacement Therapies generally associated to the Artificial Kidney (AK) are membrane-based treatments that assure separation functions of failing kidney in extracorporeal blood circulation. Their progress from conventional hemodialysis towards high-flux (HFHD) through introduction ultrafiltration membranes characterized by high convective permeation fluxes intensified need eluci...

this is a comprehensive review of the recent progresses made in the field of zeolite membranes. it describes zeolitic materials and methods of membrane fabrication, followed by a summary of applications for gas separation, pervaporation and separation of liquid mixtures. special attention is called to polymer mixed matrix membranes (mmms) and membranes based on metal organic frame works (mofs)....

For the first time, an ultrathin type of ultra-high molecular weight polyethylene (UHMWPE) membrane only 350 nm thickness is surface modified by direct fluorination and plasma treatments. Then a notable suppression in crystallinity observed. A total four kinds thickness, from to 6 µm, are investigated correlate modification effect on thickness. Microscopically, continuous shish-kebab structure ...

Gene therapy is a promising new treatment modality based on molecular genetic modification to achieve a therapeutic benefit. We believe that gene therapy in the peritoneal cavity holds considerable promise, and we describe strategies by which genetic modification can be used to treat a variety of disease states or conditions. First, we can envision a strategy, based on genetic modification of t...

In this paper, a new integrated distillation-membrane separation process solution strategy based on genetic programming (GP) was established for azeotrope separation. Then, price evaluation method the theory of unit membrane area proposed, so that those membranes which are still in experimental stage and have no actual industrial cost reference can also be used research. For different character...

sulfur mustard (sm, bis- (2-chloroethyl) sulphide) is a chemical warfare agent that causes dna alkylation, protein modification and membrane damage. sm can trigger several molecular pathways involved in inflammation and oxidative stress, which cause cell necrosis and apoptosis, and loss of cells integrity and function. epigenetic regulation of gene expression is a growing research topic and is ...

Palmitoylation, the attachment of palmitate and other fatty acids on to cysteine residues, is a common post-translational modification of both integral and peripheral membrane proteins. Dynamic palmitoylation controls the intracellular distribution of peripheral membrane proteins by regulating membrane-cytosol exchange and/or by modifying the flux of the proteins through vesicular transport sys...
