it has been encountering with large modifications and developments during recent decades and it makes large developments at rey & islamshahr regions. as the habitation areas as shaped in different dimensions. thought it can investigate the implicational structural at large scales even at littler scales too. nevertheless the essential applications of living areas on over coming life need such ha...

Changes similar to posttranslational modifications that are observed with osmotic cataract formation in vivo can be seen with homogenates of lenses. These modifications are the loss of a 31,000 molecular weight (MW) beta crystallin polypeptide, an increase in a 25,000 MW membrane polypeptide. These modifications are potentiated by calcium and occur more rapidly at 37 degrees C than at 4 degrees...

The proton pump transmembrane protein bacteriorhodopsin was successfully incorporated into planar floating lipid bilayers in gel and fluid phases, by applying a detergent-mediated incorporation method. method optimized on single supported using quartz crystal microbalance, atomic force fluorescence microscopy techniques. Neutron X-ray reflectometry were used both with the aim of determining str...

Infection of erythrocytes with the human malaria parasite, Plasmodium falciparum, results in dramatic changes to the host cell structure and morphology. The predicted functional localization of the STEVOR proteins at the erythrocyte surface suggests that they may be involved in parasite-induced modifications of the erythrocyte membrane during parasite development. To address the biologic functi...

Nutritionally induced filamentous cell forms of Escherichia coli B were examined for their morphological and biochemical lesions. The filamentous forms showed no significant alteration in total DNA concentration, RNA synthesis, ability to form beta-galactosidase in response to isopropylthiogalactoside, or insensitivity to actinomycin D as compared to the normal cell form. The filamentous cells ...

Membrane electrochemical potential is a feature of the molecular profile of the cell membrane and the two-dimensional arrangement of its charge-bearing molecules. Plasmodium species, the causative agents of malaria, are intracellular parasites that remodel host erythrocytes by expressing their own proteins on erythrocyte membranes. Although various aspects of the modifications made to the host ...

The world market for CO2/CH4 separation using membrane technology is getting bigger and polysulfone (PSf) is one of the most widely investigated polymer membrane materials. However, the existing PSf membranes performances are insufficient to fully exploit these opportunities. Therefore, modification that would produce membrane that fit the needs of target separation performances is a main issue...
