Secreted proteins are processed from a nascent form that contains an NHz-terminal signal peptide. During processing, the latter is cleaved by a specific NH2terminal signal peptidase. The nascent form of phosphatidylinositol glycan (PI-G) tailed proteins contain both an NH,and a COOH-terminal signal peptide. The two signal peptides have much in common, such as size and hydrophobicity. The COOH-t...

We report intensely staining epiretinal membrane (ERM) with Brilliant Blue G (BBG) under air for two minutes. ERM peeling was performed in 21 cases. After removal of posterior hyaloid, 0.2 mL BBG was first applied on the macula, to stain ERM under air conditions for 2 minutes. Internal limiting membrane (ILM) was intensely stained and peeled in all cases following ERM removal. In 4 cases, the E...

Heterotrimeric G proteins interact with receptors and effectors at the membrane-cytoplasm interface. Structures of soluble forms have not revealed how they interact with membranes. We have used electron crystallography to determine the structure in ice of a helical array of the photoreceptor G protein, transducin, bound to the surface of a tubular lipid bilayer. The protein binds to the membran...

This study describes a biological investigations of methanolic extract of Jatropha gossypiifolia, a plant belonging to the family Euphorbiaceae. The aim of this investigation was to expose the viable phytochemical constituents properly as their contribution towards the antioxidant, anthelmintic and membrane stabilizing activities. The anthelmintic test was conducted on earthworm Pheritima phost...

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 ...
