The majority of the 3' untranslated region (UTR) of Turnip crinkle virus (TCV) was previously identified as forming a highly interactive structure with a ribosome-binding tRNA-shaped structure (TSS) acting as a scaffold and undergoing a widespread conformational shift upon binding to RNA-dependent RNA polymerase (RdRp). Tertiary interactions in the region were explored by identifying two highly...

A new member of the genus Potexvirus was fully sequenced and characterized. The virus was isolated from babaco (Vasconcellea x heilbornii), a natural hybrid native to Ecuador. The virus contains a 6,692 nt long genome organized in five open reading frames in an arrangement typical of other potexviruses. Sequence comparisons revealed close relatedness with Papaya mosaic virus (PapMV), Alternathe...

A relationship between the friction velocity u☆ and mean wind speed U in a stable atmospheric boundary layer (ABL) over Arctic sea ice was considered. To that aim, observations collected during Surface Heat Budget of Ocean (SHEBA) experiment were used. The showed so-called “hockey-stick” shape u☆−U relationship, which consists slow increase with increasing for U<Utr more rapid almost linear ...

Crucial model synthetic and mechanistic studies directed toward the development of methodology for the construction of the maleic anhydride moiety of the CP-molecules are described. Studies directed toward the stereoselective attachment of the upper side chain, culminating in the discovery of long-range stereochemical control, are also discussed. In addition, a first-generation strategy toward ...

Four major glutamate receptor 2 (GluR2) transcripts differing in size (approximately 4 and approximately 6 kilobases) due to alternative 3' untranslated regions (UTRs), and also containing alternative 5'UTRs, exist in the brain. Both the long 5'UTR and long 3'UTR repress translation of GluR2 mRNA; repression by the 3'UTR is relieved after seizures. To understand the mechanism of translational r...

Uterine infection is one of the reproductive diseases that can have disturbing postpartum uterine health in cattle. Therefore, identification of resistant genotypes to uterine infection is important. Lactoferrin (LF) is one of the major antimicrobial compounds in the normal uterine discharges of cows. We hypothesized that allelic diversity in LF gene may contribute to susceptibility or resistan...

Background: Hepatitis C is a global health problem. The exact mechanisms by which hepatitis C virus (HCV) can evade the host immune system have become controversial. Whether HCV polyproteins modulate IFN signalling pathways or HCV proteins are responsible for such a property is the subject of interest. Therefore, an efficient baculovirus delivery system was developed to introduce the whole geno...
