large unilamellar liposomes and multilamellar vesicles consisting of dmpc interacted with cationic phosphorus-containing dendrimers cpds g3 and g4. dsc and ζ -potential measurements have shown that liposomal-dendrimeric molecular recognition occurs due to the interaction between the complementary surface groups. calorimetric studies indicate that the enthalpy of the transition of the lipids tha...

background: inversion of the uterus is very uncommon. patients may present with pelvic pain, vaginal discharge, or hemodynamic shock. case: we report a case of 35 years old women (virgin) who was admitted with profuse vaginal bleeding and cramps of uterus. in the vaginal examination at litothomy position a mass of 58 cm in size was protruded from the vagina. at first myomectomy was performed a...

RNA processing, directed transport along cytoskeletal tracks, and site-specific translation of mRNA at the cell periphery are considered discrete steps in the generation of microfilament-membrane adhesion complexes. A recently identified member of the heterogeneous nuclear ribonucleoprotein family, raver1, may couple these steps and contribute to the assembly and maintenance of these structures.

The influenza A virus genome consists of eight single-stranded negative-sense RNA (vRNA) segments. Although genome segmentation provides advantages such as genetic reassortment, which contributes to the emergence of novel strains with pandemic potential, it complicates the genome packaging of progeny virions. Here we elucidate, using electron tomography, the three-dimensional structure of ribon...

While membrane models now include the heterogeneous distribution of lipids, the impact of membrane charges on regulating the association of proteins with the plasma membrane is often overlooked. Charged lipids are asymmetrically distributed between the two leaflets of the plasma membrane, resulting in the inner leaflet being negatively charged and a surface potential that attracts and binds pos...

the reported work is on the preparation and characterization of polyvinyl alcohol -g- polyacrylic acid (pva-g-paa)/ polybenzimidazole sulfone (pbis) cation exchange membrane used for the electro dialysis of sodium chloride solution. the polymer syrup has been prepared using the grafting method with the help of polyvinyl alcohol and polyacrylic acid in the presence of water solvent. the polymer ...

a membrane bioreactor (mbr) system based on a dead-end immersed hollow fiber membrane and filamentous fungus aspergillus oryzae were used for treatment of baker’s yeast wastewater. the fungus was adapted to the wastewater in the bioreactor for two weeks before starting the continuous process. average organic loading rate of 4.2 kg cod/m3.d was entered the bioreactor. mbr system was able to redu...

Heterogeneous photocatalysis is a technology widely applied to water purification and wastewater treatment under ultraviolet (UV) or even sunlight irradiation for the removal of variety environmental pollutants into harmless species. Application membrane immobilization semiconductors their suitability in photocatalytic degradation dyes have recently been developed. Integration with processes sig...

Human cell membranes consist of various lipids that are essential for their structure and function. It typically comprises phosphatidylcholine (POPC), phosphatidylethanolamine (POPE), phosphatidylserine (POPS), sphingomyelin (PSM), cholesterol (CHL). Several experimental computational techniques have been employed to characterize the composition human membranes, however, CHL enriched membrane i...
