background and objectives:   iranian chronic hbv carrier’s population has shown a unique pattern of genotype d distri- bution all around the country. the aim of this study was to explore more details of evolutionary history of carriers based on structural surface proteins from different provinces. materials and methods: sera obtained from 360 isolates from 12 different regions of country were u...

background:isolates of staphylococcus aureus express a myriad of adhesive surface proteins that play important role in colonization of the bacteria on nasal and skin surfaces, beginning the process of pathogenesis. the aim of this study was to screen several of the microbial surface components recognizing adhesive matrix molecules (mscramms) genes among the isolate of s. aureus from hospitalize...

Cell-surface display is the expression of peptides and proteins on the surface of living cells by fusing them tofunctional components of cells which are exposed to the environment of cells. This strategy can be carriedout using different surface proteins of cells as anchoring motifs and different proteins from different sourcesas a passenger protein. It is a promising strategy...

in the past decade much effort has been devoted to the development of new expression systems and novel techniques for the surface display of heterologous proteins in yeast in order to improve their applications in biotechnology, food technology, pharmacology and medicine. heterologous protein-encoding genes are generally fused with genes coding for yeast cell wall proteins or their fragments re...

For the purpose of increasing the permeability to oxygen and equilibrium water content in contact lenses, polar copolymers with nonionic monomers such as 2-hydroxyethle methacrylate(HEMA) Is used. By adding the polar monomers to (HEMA), the permeability to oxygen and equilibrium with water content is increased and also the absorption of proteins on lens surface is changed. In this research, the...

background and objectives: streptococcus pneumoniae, a major human pathogen, is closely related to the commensal species s. mitis and s. oralis. s. pneumoniae surface proteins are implicated in virulence and host interaction of this species, but many of them have recently been detected in s. mitis b6 in silico. we tested for the presence of such genes usinga set of eight s. mitis and eleven s. ...

Crystalline surface layer proteins (S-layer proteins) have considerable potential for the crystalline arrays in biotechnology, biomimetics and nonlife applications, including areas such as microelectronics and molecular nanotechnology. The extensive application potential of surface layers in nanobiotechnology is according to the particular inherent attributes of the single molecular arrays cons...
