Bleomycins, a group of glycopeptide antibiotics differ from one another in their terminal amine moieties. 14C-Methyl-labeled 3-aminopropyl-dimethylsulfonium was confirmed to be incorporated into the amine moiety of bleomycin A2. Addition of amines of bleomycin A2, A2'-a, A2'-b, A2'-c, A5, B2 and B4 to fermentation media increased the rate of production of the bleomycin which contained the added...

The A2 genes of Leishmania donovani encode amastigote-specific A2 proteins, which are considered to be virulence factors required for the survival of this protozoan parasite in the mammalian host. The A2 genes are present within a multigene family and corresponding A2 proteins are composed predominantly of multiple copies of a 10 amino acid repeat sequences. A2-specific antibodies have been det...

early in the development of many animals, before transcription begins, any change in the pattern of protein synthesis is attributed to a change in the translational activity or stability of mrna in the egg and early embryo. as a result, translational control is critical for a variety of developmental decisions, including oocyte maturation and initiation of preimplantation development. in this s...

results in a group of adult patients with chb, anxa2 values were far higher than those of the control group (p = 0.001). when we assessed anxa2 levels based on fibrosis stages, serum anxa2 levels of patients with early stage fibrosis (stages 1 - 3) were significantly higher than those of patients with advanced stage fibrosis (stages 4 - 5; p = 0.001). patients and methods this study included 17...

conclusions sch is associated with increased level of pla2-iia, which is independent of bmi. the stronger association of sch with pla2-iia than with hs-crp indicates that pla2-iia is an inducer of inflammation while hs-crp is not. results serum levels of tg, cholesterol, and ldl were higher in the sch group than the control group. however, there was no significant difference between the two gro...

The results of the study heat transfer under forced convection in a flat porous microchannel taking into account boundary conditions slippage first and second order are considered.
 simulation showed that with decreasing porosity flow velocity central part slipping on wall decrease due to increase hydrodynamic resistance. Taking influence shows magnitude jump varies depending value paramet...
