introduction: methicillin-resistant staphylococcus aureus (mrsa) is responsible for an increasing number of serious hospital- and community-acquired infections. usa300 is known to be the most common cause of community-acquired infections, but recently there have been some reports on hospital-acquired infections caused by this strain. methods: totally 171 isolates of s. aureus were collected fro...

Pirashvili exhibited a small subcomplex of the Leibniz complex $$(T(s {\mathfrak {g}}), d_{\textrm{Leib}})$$ algebra $${\mathfrak {g}}$$ . The main result this paper generalizes to show that primitive filtration $$T(s{\mathfrak {g}})$$ provides an increasing, exhaustive by subcomplexes, thus establishing conjecture due Loday. associated spectral sequence is used give new proof Pirashvili’s that...

We introduce the sequence spaces [ ˆ w(M)] and [ ˆ w(M)] θ of strong almost convergence and lacunary strong almost convergence respectively defined by the Orlicz function M. We establish certain inclusion relations and show that the above spaces are same for any bounded sequences. 1. Definitions and notations A sequence x ∈ l ∞ , the space of bounded sequences x = (x k), is said to be almost co...

Rat liver glutathione S-transferase 3-3 (GST, EC 2.5.1.18), a triple mutant with all three cysteine residues replaced with serine (CallS) and a quadruple mutant with a Tyr-115 to phenylalanine substitution on CallS (CallSY115F) were overexpressed in Escherichia coli under the control of a phoA promoter. Using this system, we obtained over 35 mg of fully active pure protein/litre of cell medium....
