Newly synthesized membrane proteins are transported by fast axonal flow to their targets such as the plasma membrane and synaptic vesicles. However, their transporting vesicles have not yet been identified. We have successfully visualized the transporting vesicles of plasma membrane proteins, synaptic vesicle proteins, and the trans-Golgi network residual proteins in living axons at high resolu...

In the present work, B-ZSM-5 zeolite membranes were synthesized on porous tubular α-alumina supports by several subsequence in situ crystallization hydrothermal treatments. The TiO2- Bohmite and ɣ- alumina intermediate layers were applied to improve the lattice matching between zeolite layer and the support. The uniform membrane intermediate layers with low permeation resistance were...

Poly (amide-6-b-ethylene oxide)/Zinc Oxide (PEBA/ZnO) mixed matrix membranes were fabricated using ethanol/water as solvent by solvent casting method. The concentration of ZnO in membrane was set to 0.1 wt.% and the synthesized membranes were characterized by AFM and FTIR. Effects of ZnO nanoparticle on CO2, CH4 and N2 permeabilities, and CO2/N2<...

Nowadays, oily wastewater is increasing along with the growth of various industries. So, wastewater treatment is necessary in order to protect the environment. In this study, a mullite ceramic membrane was prepared. Then, oily wastewater treatment with 200 mg L-1 concentration was investigated by the response surface methodology based on Box-Behnken design (BBD) using Design-Expert 7...

Sudden cardiac death (SCD) is usually due to ventricular fibrillation and can occur as a first manifestation of heart disease. Prevention of ventricular fibrillation and SCD with n-3 polyunsaturated fatty acids is well documented. Trans-fatty acids (TFA) in the diet and cell membranes might affect the risk of SCD as well. We review evidence from an observational study that high levels of trans-...

Trans-sialidase is a membrane-bound and shed sialidase from Trypanosoma cruzi, the protozoan parasite responsible for Chagas disease. We investigated the role of soluble trans-sialidase on host CD4+ T cell activation. Trans-sialidase activated naive CD4+ T cells in vivo. Both enzymatically active and inactive recombinant trans-sialidases costimulated CD4+ T cell activation in vitro. Costimulati...

Poly (ether-block-amide) /poly (ethylene glycol)/ carbon nanotubes mixed matrix membranes have been successfully fabricated using solvent evaporation method to determine the effect of ethylene oxide groups on the performance of produced membranes. The effects of CNTs (2-8 wt%) and PEG (up to 50 wt%)were investigated in both single and mixed gas test setup in different temperature and pressure. ...

direct contact membrane distillation (dcmd) which emerges as an alternative separation technology can effectively perform a colloidal separation process under thermal driven force. dcmd is capable of extracting pure water from aqueous solutions containing non-volatile nanoparticles through the hydrophobic microporous membrane when a vapour pressure difference was established across the membrane...
