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...

We have adapted the originally described electronic PCR (e-PCR) algorithm to perform string searches more accurately and much more rapidly than previously possible. Our implementation [multithreaded e-PCR (me-PCR)] runs sufficiently fast to allow even desktop machines to query quickly large genomes with very large genomic element sets. In addition, me-PCR is multithreaded, interprets all IUPAC ...

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...

introduction: acinetobacter baumannii is associated with hospital-acquired infections. outer membrane protein a of a.baumannii (abompa) is a well-characterized virulence factor which has important roles in pathogenesis of this bacterium. methods: based on our pcr-sequencing of ompa gene in the clinical isolates, abompa protein can be categorized into two types, named here type-1 and type-2. we ...

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...

lactoferrin (lf) is an iron-binding multi-functional glycoprotein which has numerous physiological functions such as iron transportation, anti-microbial activity and immune response. in this study, different in silico approaches were exploited to investigate lf protein properties in a number of mammalian species. results showed that the iron-binding site, dna and rna-binding sites, signal pepti...

The haemolytic biovar of Gallibacterium anatis (G. anatis) is responsible for urogenital, gastrointestinal, and respiratory diseases in chickens. There are numerous reports on the resistance of G. anatis to antibiotics and recurrence of the disease, which raise concerns about antimicrobial treatment efficiency. Vaccination has been considered as the most feasibl...

Background: Non-coding RNAs apply regulations on expression or function of a gene. A class of non-coding RNAs, natural antisense transcripts, might overlap with their flanking genes and emerge a new complexity upon regulation. WRAP53, is a natural antisense transcript overlapped in a head-to-head manner on the opposite strand of TP53. It has 3 transcripts of which WRAP53β produ...
