The highly conserved internal ribosome entry site (IRES) of hepatitis C virus (HCV) regulates translation of the viral RNA genome and is essential for the expression of HCV proteins in infected host cells. The structured subdomain IIa of the IRES element is the target site of recently discovered benzimidazole inhibitors that selectively block viral translation through capture of an extended con...

garlic, an antioxidant plant, can react with amino groups of proteins to form schiff bases. as diabetes leads to glycation of various proteins and this in turn has some effects on the structure of proteins and biochemical activity of them, the inhibition of this process seems very vital. for several years researchers in this field have done their best to recognize the antidiabetic compounds. th...

conclusions these results indicate that a. kellalensis extracts exert potent anti-rotaviral activity only after viral adsorption. the two extracts from a. kellalensis showed a good selectivity index. also these results suggest that extracts prepared from the flowers of a. kellalensis may be potential anti-rotaviral agents in vivo and be useful in veterinary medicine. background achillea kellale...

materials and methods the subjects included 27 male and 3 female patients with advanced chronic periodontitis. the mean age of the patients was 47.6 ± 2.0 years old. p. gingivalis was isolated from the samples and identified by various diagnostic tests, including gram staining, indol test, and fluorescent test. minimum inhibitory concentration (mic) of the essential oil against isolated p. ging...

The protein IF2/eIF5B is one of the few translation initiation factors shared by all three primary domains of life (bacteria, archaea, eukarya). Despite its phylogenetic conservation, the factor is known to present marked functional divergences in the bacteria and the eukarya. In this work, the function in translation of the archaeal homologue (aIF2/5B) has been analysed in detail for the first...
