In this work, a bulk liquid membrane method has been applied for Ni enrichment and separation from natural waters. The carrier-mediated transport was accomplished by pyridine-2-acetaldehyde benzoylhydrazone dissolved in toluene as a complexing agent. The preconcentration was achieved through pH control of source and receiving solutions via a counterflow of(More)
During translation initiation, eukaryotic initiation factor 2 (eIF2) delivers the Met-tRNA to the 40S ribosomal subunit to locate the initiation codon (AUGi) of mRNA during the scanning process. Stress-induced eIF2 phosphorylation leads to a general blockade of translation initiation and represents a key antiviral pathway in mammals. However, some viral(More)
Location of the translation initiation codon generally requires scanning of the 43S ribosomal preinitiation complex (43S PIC) from the 5' of the mRNA. Associated RNA helicases can facilitate movement of the 43S PIC by removing secondary structure present in the 5' UTR of mRNA, which is required for codon inspection. The canonical RNA-dependent helicase(More)
