in this study the effect of a methylated derivative of nitrogen mustard (mechloroethamin) on solubilized and reconstituted chromatin was investigated using uvnis spectroscopy, dna and sds gel electrophoresis and densitomeoic scanning techniques, the results indicated that the 210 and 260 nm absorbances of reconstituted chromatin were decreased in a dose-dependent manner after treatment with var...

there are more than 350 million individuals with hepatitis c in the world. one of the important problems in vaccine project is development of effective and suitable adjuvant in human vaccines. at present research we applied human βhsp90 protein as an adjuvant in recombinant hcv vaccine design. the thermal vector of pgp1-2 was used for human heat shock protein 90 expression. this protein injecte...

dna coding for the core antigen from hepatitis b virus (hbcag) was amplified, cloned and propagated in e. coli. the core protein was expressed in e. coli and the product was readily detected by western blot. this protein can be used as a diagnostic material in serum screening tests. to increase the level of expression of this antigen in bacteria, two plasmids were constructed in which the gene ...

The purpose of the present work is to introduce the concept of bifuzzy core of a fuzzy automaton, which induces a bifuzzy topology on the state-set of this fuzzy automaton. This is shown that this bifuzzy topology can be used to characterize the concepts such as bifuzzy family of submachines, bifuzzy separable family and bifuzzy retrievable family of a fuzzy automaton.

Core-shell nanostructures are emerging as more important materials than alloy nanostructures and have much more interesting potential applications in various fields. In this work, we demonstrated the fast and facile synthesis of core-shell nanoparticles consisting of Pt thin layer as the shell and Ni nanoparticles as the cores. The described method herein is suitable for large-scale and low-cos...
