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 ...

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...

ABSTRACT In this study, we isolated and characterized HSP70 cDNA from pufferfish (Takifugu rubripes). The 3053 bp full-length TrHSP70 sequence consisted of a 167 5′-UTR (untranslated region), 2535 open reading frame, 351 3′-UTR. BLAST analysis revealed that the shared high similarity with sequences in other species. our set 3 experimental groups as H1 group (20 °C), H2 (24 H3 (28 °C) for checki...

conclusions sequence and structural diversity of the 3'utr variable region and poly u/uc region found in the local isolates indicate specificity in the regulating elements of 3'utr that might be associated with differential replication efficacy of the hcv pakistani isolates. the study necessitates functional characterization of these regulating elements to elucidate variable viral eff...

Urotensin II and the associated urotensin II receptor (UTR) are important in the carcinogenesis of hepatocellular carcinoma (HCC). However, the clinical significance of UTR remains to be elucidated. The aim of the present study was to investigate if UTR exhibits the potential to act as a biomarker to predict the prognosis of HCC patients. The effects of UTR on motility and invasion of HCC cells...

BACKGROUND Since the end of last century, RNAs from the 3'untranslated region (3'UTR) of several eukaryotic mRNAs have been found to exert tumor suppression activity when introduced into malignant cells independent of their whole mRNAs. In this study, we sought to determine the molecular mechanism of the tumor suppression activity of a short RNA from 3'UTR of C/EBPβ mRΝΑ (C/EBPβ 3'UTR RNA) in h...

Classical swine fever virus (CSFV) causes a broad range of disease in pigs, from acute symptoms including high fever and hemorrhages, to chronic disease or unapparent infection, depending on the virus strain. CSFV belongs to the genus Pestivirus of the family Flaviviridae. It carries a single-stranded positive-sense RNA genome. An internal ribosomal entry site (IRES) in the 5' untranslated regi...
