although spinal cord injury (sci) is one of the most common injuries after a road accident, there is no definite treatment for it. in this regard, nanotechnology has focused to retrieve damaged tissue function by designing of a biomaterial as a mimicking extracellular matrix to reduce inflammation, scar and lactate dehydrogenase, to fill the cyst and improve the graft integration, cell prolifer...

In article numer 20200081, Damia Mawad and co-workers highlight the importance of coupling conjugated polymers polyelectrolytes with lipid bilayer to engineer interfaces unique characteristics, facilitated by accessing properties each constituent material. Conjugated provide optical electronic properties, whereas mimics biological cell, enabling fusion cell membrane. The cover summarises how ut...

Distribution of contact pressure between the bipolar plate and gas diffusion layer considerably affect the performance of proton exchange membrane fuel cell. In this regard, an adaptive neuro-fuzzy inference system (ANFIS) is developed to predict the contact pressure distribution on the gas diffusion layer due to dimensional errors of the bipolar plate ribs in a proton exchange membrane fuel ce...

introduction: the major histocompatibility complex (mhc) is a group of cell surface proteins that are essential for recognizing foreign molecules in human and other mammals. the physiologic function of mhc molecules is the presentation of peptides to t cells. in this study, we evaluated the purification of a class ii mhc molecule (hla-dr) from a human burkitt′s lymphoma cell line; daudi. materi...

endoplasmic reticulum has a critical role in the synthesis and folding of secretory and membrane proteins. high accumulation of proteins in er activates the unfolded protein response and glucose regulated protein 78 or gpr78 plays an essential role in this pathway.  unfolded protein response is activated in cancerous cells due to their adverse condition to survive and it has been shown that grp...

In this work membrane (proton exchange membrane) by using the blend polymers (polyethersulfone (PES), Expandable polystyrene (EPS), polyvenylidinefluride polymer (PVDF)) were prepared. This was modified adding organic sulfonic acid to solution precasting process, and sulfonated dipping it in diluted sulfuric (H2SO460%) post casting process. The sulfonation confirmed via FTIR spectra. characteri...

Abstract In Chapter 8, we introduced mathematical models of the action potential across a cell membrane. Understanding properties membrane is absolutely essential in order to understand electrophysiology excitable cells. However, some can only be studied spatially resolved models; i.e., representing spatial variation single or collection

Abstract The aim of the study is to find cheap catalysts for oxidation ethanol and release oxygen in alkaline alcohol fuel cells. catalytic activity gold-plated copper substrates coated with silver foam an membrane-free cell has been investigated. In this cell, phase interface between two highly immiscible liquids acts as a membrane. medium allows use non-platinum catalysts, which, together abs...

Most mechanisms involved in neuronal maintenance and function are activated at the membrane. Membrane-related molecular agents, which interact protein/lipid clusters to begin processing signal transduction, required for these functions. Furthermore, many neuropathological disorders originate this structure and/or result of membrane malfunction. Although precise maintaining "membrane health" unk...
