Synthesis and DNA-binding studies with two stericallyfriendly porphyrin frameworks
… the mode of binding varies with the base composition of the DNA host. The porphyrin binds adenine-thymine rich sequences externally whereas intercalation occurs in guanine-cytosine rich sequences. The McMillin group has made some dicationic porphyrins which are strictly intercalators …

Gold nanoshells for surface enhanced Raman spectroscopy and drug delivery
… silica cores wrapped with thin layer of Au. Based on the size of the Au layer with respect to the silica core, gold nanoshells can resonantly absorb or scatter light at any wavelength on the visible or infrared. On resonance, gold nanoshells interact strongly with light to give rise to …

Studies on the Metabolism of Plant Cells in Tissue Culture
… released only RNA with the ribosomal type of base composition. Similar extractions in the presence of high salt concentrations released this RNA together with DNA and rapidly-labelled RNA. 10. During short treatments with (32P) orthophosphate, exponential-phase cells synthesised RNA with a …

Tissue-specific classification of alternatively spliced human exons
… as exon and intron length, splice site strength, base composition, conservation, modularity, and susceptibility to nonsense-mediated mRNA decay caused by skipping. Cis-element motifs that might bind protein factors that affect splicing were identified using overrepresentation analysis and …

Economic advancement or social exclusion? : less-educated workers, cost-of-living and migration in high-tech regions
… 1990s, I show that shifts in regional economic-base composition towards a greater concentration of high-tech activity cannot be held on its own responsible for exclusionary patterns in these regions.

Global Microsatellite Content Potentially Distinguishes Humans, Primates, Animals, and Plants
… validates data from published sequence databases and is a sensitive and specific gauge of mutation in an in vitro model of microsatellite instability, an MLH1 knockout (RKO6) cell line. Moreover, we demonstrate that microsatellite content varies predictably by species, and that particular …

Motility studies and taxonomy of a rod-shaped bacterium with unusual flagellar fascicles, Aquaspirillum fasciculus sp. nov.
… to genus Aquaspirillum. This decision was based on the following considerations: large bipolar fascicles of flagella, a strictly respiratory metabolism, inability to attack carbohydrates, presence of intracellular poly-β-hydroxybutyrate granules, positive reactions for catalase, oxidase and …

MUPrimer : a tool for finding allele specific PCR-primers for homologous gene sequences
… from a single input DNA target with particular base composition, length, and position within the input DNA target. However, when the template DNA is from complex genomes or in mixtures of target DNAs, primer picking must be more sophisticated to enable discrimination of closely related sequences …

A taxonomic study of the Spirillum lipoferum group, with descriptions of a new genus, Azospirillum gen. nov., and two species, Azospirillum lipoferum (Beijerinck) comb. nov. and Azospirillum brasilense sp. nov.
… having a cell diameter of 1.0 μm) and had a DNA base composition of 69 - 71 mol% G + C (Tm). When grown in broth the cells had a single polar flagellum, but when grown on agar at 30°C they also formed numerous lateral flagella of shorter wavelength. DNA homology experiments using a membrane …

The Influence of Osmolytes on Nucleic Acid Helical Conformations
… A-form like to B-form like, depending on the base composition of each strand. In the presence of macromolecular crowding agents, the conformations shifted to more A-form like while in the presence of osmolytes the conformations shifted to more B-form like. These results suggest that the …

Delivery and stability of antisense oligonucleotide conjugates in vitro
… moieties on lysosomal stability. The effects of base composition and length on stability in a lysosomal extract revealed the longest half-life for homo-cytidine ODNs and ODNs over 20 nucleotides in length. These studies suggest that the above conjugates can enhance cellular association and …

A taxonomic study of the genus Spirillum ehrenberg, with special reference to nutrition and carbohydrate catabolism
… physiological, nutritional, serological, and DNA base composition similarities. The two species O. linum (formally Spirillum linum) and O. atlanticum (formally Spirillum atlanticum), were also combined into a single species (O. atlanticum) because of their similarities. Previously unnamed strains …

Cloning and characterization of glycogen synthase from Dictyostelium discoideum
… technique, enrichment-PCR, that relies on the base composition of the Dictyostelium genome. Due to the high A+T content of the Dictyostelium genome, a polyT primer and a gene specific primer were used to amplify an unknown DNA fragment, flanking a known sequence. Analysis of the complete coding …

Incorporation of CpG Oligodeoxynucleotides into α2-Macroglobulin: Development of a Novel Vaccine Adjuvant Delivery Mechanism
… LRP, and is then trafficked to the endosome. Based on these interactions, α2M seems to play an important role at sites of infection and inflammation by controlling the level of proteinase activity, modulating cytokine signals, and enhancing antigen processing for the adaptive immune response. …

Development of multi-component iron-based amorphous alloy
… rather than modifying a known glass forming composition, and assessing its glass forming ability. Iron (Fe) was chosen as the solvent element because it is significantly cheaper than the base elements found in some other metallic glasses and does not require the addition of large quantities …

Purification and properties of some fresh water and marine cyanobacteria belonging to the orders Chamaesiphonales and Pleurocapsales
… temperature relationships; heterotrophy; pigment composition; and mean DNA base composition. There were no clear-cut correlations between genera defined in terms of developmental patterns and groups defined in terms of any of the physiological and chemical properties examined. However, many of the …

Gene Activation in Early Amphibian Development
… a high molecular weight heterogeneous RNA. Its base composition approaches that of DNA. 30% of the label appears in transfer RNA. At the early blastula stage only a very small amount of heterogeneous RNA is synthesized.</p>

The influence of nickel-nitrogen ratio on the deformation behaviour of austenitic stainless steels
… of ten alloys, each having a type 301 base composition, but systematically varying nickel-nitrogen ratios, were characterized before and after tensile deformations using optical and electron microscopy as well as X-ray diffraction techniques. Tensile tests were performed on solution …

The Structure and Replication of a Parainfluenza Virus
… On the basis of its ribonuclease sensitivity, base composition, and sedimentation behavior, SV5 RNA appears to be single-stranded. The methods used in the studies of SV5 were applied to pneumonia virus of mice (PVM), an unclassified virus whose structure had not been previously determined. PVM …
