A novel, extremely halophilic archaeon B3(T) was isolated from shrimp-salted seafood. Its morphology, physiology, biochemical features and 16S rRNA gene sequence were characterized. Strain B3(T) is non-motile, Gram-variable, requires at least 10 % (w/v) NaCl for growth and grows in the ranges of 21-50 degrees C and pH 6.5-9.0. The DNA G+C content of strain B3(T) was 63.2 mol%. Phylogenetic anal...

The exonuclease1 (Exo1) gene is a key component of mismatch repair (MMR) by resecting the damaged strand, which is the only exonuclease involved in the human MMR system. The gene product is a member of the RAD2 nuclease family and functions in DNA replication, repair and recombination. However, whether Exo1 is required to activate MMR-dependent DNA damage response (DDR) remains unknown, the con...

Introduction: Recent advances in nanoscience and biomedicine have attracted tremendous attention over the past decade to design and construct multifunctional nanoparticles that combine targeting, therapeutic, and diagnostic functions with a single platform to overcome the problems of conventional techniques for diagnosis and therapy with minimal toxicity.   Materials ...

We report the isolation, for the first time by phage display, of a scFv recombinant antibody called B3 directed against carrageenans, the major sulphated polysaccharides of red seaweeds. Immunoassays were used to characterize the binding of B3 antibodies toward the three main carrageenan forms (iota, kappa, and lambda) differing by their sulfonic ester content and the presence of 3,6-anhydrogal...

the high molecular weight glutenin subunit (hmw-gs) compositions of 19 diploid wild wheat (t.boeoticum) and 36 diploid wild wheat (a.tauschii) were determined by sodium dodecyl sulphate polyacrylamide gel electrophoresis (sds-page). all of t. boeoticum were characterized for their hmw-gs, showed 2* in their glu-a1 locus. in the study of aegilops tauschii that were collected from iran and 7 neig...
