le besoin croissant de logement et le desir dameliorer la qualite, la securite et la durabilite des batiments, et de diminuer leur prix de revient, ont necessite des recherches etendues dans le domaine des materiaux de la construction. le beton silico-calcaire peut etre considere comme une des reussites remarquables de ces recherches. / le beton silico-calcaire est obtenu par l*acceleation de l...

in this work, we reported the synthesis and evaluation of antimycobacterial and antifungalactivity of a series of thiocarbohydrazone derivatives which are thiacetazone congeners. thetarget compounds were synthesized in superior yields by reacting thiocarbohydrazide withdifferent aromatic aldehydes and methyl ketones. compounds 8, 19 and 25 were found to bethe most potent derivatives, exhibiting...

hnf4a-p.i463vvariant, reported previously in two distinct families suspected of mody-1, is assessed in this report to determine whether it is a mutation or a polymorphism (frequency >1%).200 tunisian healthy people were screened for the presence of hnf4a-p.i463v variant, using rflp-pcr technique and sequencing. then, the frequency of this variant was estimated in the tunisian population and com...

hirudin is an anticoagulant agent of the salivary glands of the medicinal leech. recombinant hirudin (r-hir) displays certain drawbacks including bleeding and immunogenicity. to solve these problems, cysteine-specific pegylation has been proposed as a successful technique. however, proper selection of the appropriate cysteine residue for substitution is a critical step. this study has, for the ...

MOTIVATION We developed a technique and a tool for degenerate primer design based on multiple local alignments employing the MEME algorithm supported with electronic PCR. The objective is to find adequate primers starting from sequences with poor global similarity. We show an example of its application in our laboratory to find sequences in Brachiaria with similarity to ESTs related to apomixis.

background: sigma factors are proteins that regulate transcription in bacteria. sigma factors can be activated in response to different environmental conditions. the rpos (rna polymerase, sigma s) gene encodes sigma-38 (σ38, or rpos), a 37.8 kda protein in pseudomonas aeruginosa (p. aeruginosa) strains. rpos is a central regulator of the general stress response and operates in both retroactive ...
