Gas phase thermodynamic equilibrium calculations involving N 2 /B 2 H 6 /CH 4 /H 2 mixtures were performed to investigate the chemical interactions leading to boron incorporation and microstructure variations in microwave plasma assisted chemical vapor deposition of diamond films. Molecular fractions of several BH x (x=1–3) species were calculated to...
While many of the characteristics of the cosmic unidentified infrared (UIR) emission bands observed for interstellar and circumstellar sources within the Milky Way and other galaxies, can be best attributed to vibrational modes of the variants of the molecular family known as polycyclic aromatic hydrocarbons (PAH), there are open questions that need to be resolved. Among them is the observed strength...
The inhibition of human telomerase has been explored using peptide conjugated derivatives of a PNA pentamer directed at the RNA template of telomerase. It is demonstrated that the presence of cationic peptides at the N-terminus of the PNA results in enhanced inhibition of telomerase activity. Furthermore, inhibition depended on the specificity of PNA recognition.
The synthesis of oligodeoxyribonucleotide 13mers conjugated to cholic, folic, lipoic and pantothenic acids through thioether and disulphide bonds is described employing a convenient methodology which involves initial preparation of cysteinyl derivatives of the acids on solid phase.
