As pathogens continue to evade therapeutical drugs, a better understanding of the mode of action of antibiotics continues to have high importance. A growing body of evidence points to RNA as a crucial target for antibacterial and antiviral drugs. For example, the aminocyclitol antibiotic streptomycin interacts with the 16S ribosomal RNA and, in addition,(More)
BACKGROUND The peptide antibiotic viomycin inhibits ribosomal protein synthesis, group I intron self-splicing and self-cleavage of the human hepatitis delta virus ribozyme. To understand the molecular basis of RNA binding and recognition by viomycin, we isolated a variety of novel viomycin-binding RNA molecules using in vitro selection. RESULTS More than(More)
Nuclease resistance and RNA affinity are key criteria in the search for optimal antisense nucleic acid modifications, but the origins of the various levels of resistance to nuclease degradation conferred by chemical modification of DNA and RNA are currently not understood. The 2'-O-aminopropyl (AP)-RNA modification displays the highest nuclease resistance(More)
The RNA strand in an RNA/DNA duplex with unpaired ribonucleotides can undergo self-cleavage at bulge sites in the presence of a variety of divalent metal ions (Hüsken et al., Biochemistry, 1996, 35:16591-16600). Transesterification proceeds via an in-line mechanism, with the 2'-OH of the bulged nucleotide attacking the 3'-adjacent phosphate group. The(More)
"Broad-scale demographic changes have implications for state and local finance in terms of the composition of the base of revenue sources and their yields. This article examines the effect of such changes on the potential future yield of consumption-based taxes. The effect of household characteristics and composition on the consumption of selected groups of(More)
Microsoft came to Blur seeking a cutting-edge teaser that would add impact and energy to the unveiling of its future X-Box gaming console. With the visceral and energetic ''Two to Tango'' that Blur created, we were able to convey the emotion, intensity, and visual splendor that video games on the X-Box will possess in the very near future.
