The complete sequence of the single-stranded, (+)-sense RNA genome of saguaro cactus carmovirus (SCV) has been determined. The 3879 nucleotide genome contains five open reading frames (ORFs). The 5'-proximal ORF encodes a 26 kDa protein (p26) and terminates with an amber codon which is readthrough into an in-frame p57 ORF to generate an 86 kDa fusion protein (p86). Two small, centrally located ...

Both the recognition of HIV-infected cells and the immunogenicity of candidate CTL vaccines depend on the presentation of a peptide epitope at the cell surface, which in turn depends on intracellular antigen processing. Differential antigen processing maybe responsible for the differences in both the quality and the quantity of epitopes produced, influencing the immunodominance hierarchy of vir...

Hair cells, the inner ear's sensory cells, are characterized by tens to hundreds of actin-rich stereocilia that form the hair bundle apparatus necessary for mechanoelectrical transduction. Both the number and length of actin filaments are precisely regulated in stereocilia. Proper cochlear and vestibular function also depends on actin filaments in nonsensory supporting cells. The formation of a...

Systemic administration of MK-801, an NMDA-receptor antagonist, impairs reversal learning in weanling rats [Chadman, K.K., Watson, D.J., & Stanton, M.E. (2006). NMDA-receptor antagonism impairs reversal learning in developing rats. Behavioral Neuroscience, 120(5), 1071-1083]. The brain systems responsible for this effect are not known in either adult or young animals. This study tested the hypo...

Hepatitis B virus (HBV) gene expression is downregulated in the liver of HBV transgenic mice by a posttranscriptional mechanism that is triggered by the local production of gamma interferon (IFN-gamma) and tumor necrosis factor alpha (TNF-alpha) during intrahepatic inflammation (hepatitis). The molecular basis for this antiviral effect is unknown. In this study, we identified three HBV RNA-bind...

Neovascular retinopathies are leading causes of irreversible blindness. Although vascular endothelial growth factor (VEGF) inhibitors have been established as the mainstay of current treatment, clinical management of these diseases is still limited. As retinal impairment involves abnormal neovascularization and neuronal degeneration, we evaluated here the involvement of galectin-1 in vascular a...

This paper examines Moldova’s performance in the area of Macroeconomic stabilisation since independence. Analysis of key indicators such as prices, the budget, monetary growth and output reveal that after initial problems progress has been relatively satisfactory more recently. Furthermore, political developments have not impeded reforms to a great extent as they have in other post Soviet repub...
