objective(s) staphylococcus aureus is a foremost source of numerous nosocomial and community acquired infections. antibiotic therapy for vancomycin resistant s. aureus (vrsa) can not promise the eradication of infections. since adhesion is the major route of infections, adhesin based vaccine could suppress s. aureus infections. fibronectin binding protein a (fnbpa) and clumping factor a (clfa) ...

Methicillin-resistant Staphylococcus aureus (MRSA) is a challenging infectious agent worldwide. The ever growing antibiotic resistance has made the researchers to look for new anti-staphylococcal agents. Autolysins are staphylococcal enzymes that lyse bacterial cell wall for cell division. Autolysins can be used as novel enzybiotics (enzymes have antibiotic effects) for staphylococcal ...

Background: Fusion of dendritic cells (DCs) with melanoma cells could reinforce the antigenicity of tumors as a strategy for the treatment of malignant melanoma. However, the insufficient quantity of DCs and the low fusion efficiency limits the development of such approach. Objective: To define the dosage of the stimulating factors as well as the induction condition for the optimal DCs prepara...

the herpes simplex virus type 1 (hsv-1) tegument protein, vp22 has been reported to have the property of intercellular transport. the previous studies have shown that following expression of a fusion protein containing vp22 it spreads to every cell in a monolayer and concentrates in the nucleus. in spite of these reports, some studies have shown that vp22 trafficking and its nucleus accumulatio...

in this paper we investigate a new notion of bases in hilbert spaces and similarto fusion frame theory we introduce fusion bases theory in hilbert spaces. we also introducea new denition of fusion dual sequence associated with a fusion basis and show that theoperators of a fusion dual sequence are continuous projections. next we dene the fusionbiorthogonal sequence, bessel fusion basis, hilbe...

objective: the aim of this study was to construct a pcdna3.1+ vector containing fmdv type o/irn/1/2007-vp1 gene, protein expression in bhkt7 cells and evaluation of immune response in balb/c mice. materials and methods: fmdv type o/irn/1/2007 was isolated from a cattle in ray in 2007 and serotyped. the purified vp1 gene was sub-cloned into the ptz57r/t vector and pcdna3.1+ expression vector. t...

in this study, mutant forms of bacillus thuringiensis spp. israelensis (h14) were produced. these mutants were identified when the cells were cultured on chloramphenicol plates and stained with crystal violet. protoplasts of the mutants were isolated by enzymatic digestion (lysozyme) of the cell walls at the presence of an osmotic stabilizer. the protoplasts were induced to fuse to each other i...

Background: This study was conducted in order to determine whether BCB staining performed on immature bovine oocytes to assess G6pdhlevel has an impact on ivf/ivp technology in bovine embryos. Both spermatozoa and oocytes metabolize glucose through the pentose phosphate pathway (PPP), and NADPH appears necessary for gamete fusion. Activity of glucose 6-phosphate dehydrogenase (G6PDH), the key e...
