We investigate the local metrizability of Finsler spaces with $m$-Kropina metric $F = \alpha^{1+m}\beta^{-m}$, where $\beta$ is a closed null 1-form. show that such space Berwald type if and only (pseudo-)Riemannian $\alpha$ 1-form have very specific form in certain coordinates. In particular, when signature Lorentzian, belongs to subclass Kundt class generates corresponding congruence, this ge...

We provide a consistent framework to set limits on properties of light sterile neutrinos coupled all three active using combination the latest cosmological data and terrestrial measurements from oscillations, $\beta$-decay neutrinoless double-$\beta$ decay ($0\nu\beta\beta$) experiments. directly constrain full $3+1$ active-sterile mixing matrix elements $|U_{\alpha4}|^2$, with $\alpha \in ( e,...

The frequency and concentration of specific factors binding beta 2 microglobulin were investigated in sera and synovial fluids of patients and in sera of normal controls. High anti-beta 2 m activity was detected in the sera of adult RA patients, particularly in those of with extra-articular disease. Similarly, anti-beta 2 m was present in the synovial fluids of RA but not of osteoarthrosis pati...

BACKGROUND Emergence of extended-spectrum beta-lactamases (ESBLs) in Shigella species imparting resistance to third-generation cephalosporins is a growing concern worldwide. The aim of this study is to molecularly characterize the newly emerging beta-lactam resistant Shigella sonnei, specifically ESBLs in Lebanon, and compare them to beta-lactam sensitive isolates. METHODOLOGY We compared fiv...

To investigate the role of CD8+ T lymphocytes in recovery from influenza pneumonia, we used transgenic mice either homozygous (-/-) or heterozygous (+/-) for beta 2-microglobulin (beta 2-M) gene disruption. These mice lack major histocompatibility complex-restricted class I (CD8+) T cells. We found that after challenge with a nonlethal influenza virus, the beta 2-M (-/-) mice had significantly ...

We present the draft genome of highly drug-resistant Klebsiella pneumoniae KGM-IMP216, isolated from a urine sample collected from a patient in Lebanon. The draft genome sequence consisted of 77 contigs, including a combined 5,731,500 bases with 57% G+C content.

OBJECTIVES The multiresistance plasmid pKP96 from Klebsiella pneumoniae was sequenced completely and analysed concerning its genetic environment and distributing of antimicrobial resistance genes. METHODS The complete sequence of the plasmid was determined using a whole-genome shotgun approach. MICs of 13 antimicrobial agents were determined using Etests. A conjugation experiment was performe...

Cephalosporin-resistant Escherichia coli has been increasingly reported worldwide. In this study, 32 cephalosporin resistant E. coli isolates identified from cancer patients in Cairo, Egypt in 2009-2010 were analyzed. Twenty-three were of phylogenetic group D, seven A and one each B1 and B2. By rep-PCR 15 phylogroup D isolates were grouped in four clusters, one with sequence type (ST) 405 and t...

ESBL-producing bacteria are present in wildlife and the environment might serve as a resistance reservoir. Wild gulls have been described as frequent carriers of ESBL-producing E. coli strains with genotypic characteristics similar to strains found in humans. Therefore, potential dissemination of antibiotic resistance genes and bacteria between the human population and wildlife need to be furth...

Semiautomated agarose electrophoresis and immunofixation performed with Hydrasys-Hyrys (Sebia) were compared with conventional, manually performed methods, including cellulose acetate electrophoresis, immunoelectrophoresis, and immunofixation. Reference intervals for agarose electrophoresis with Hydrasys-Hyrys were determined. Within-run imprecision (CV) for fraction quantitation with the semia...
