conclusions consequently, small diameter scnt interaction with nucleic acid bases is noncovalent. also, the results revealed that small diameter scnt interaction especially scnt (4, 4) with nucleic acid bases can be useful in practical application area of biomedical fields such detection and drug delivery. objectives hence, the quantum mechanics (qm) method based on ab initio was used for this ...

Nucleic acids are biologically active materials, and chemically modified nucleic acids are now being used in nucleic acid drugs. DNA, one of the two types of nucleic acids, can also be used as a material to construct DNA-based delivery systems, such as DNA hydrogel, for therapeutic compounds. Use of chemically modified nucleic acids would greatly increase the therapeutic potency of such DNA-bas...

An investigation has been made of the changes in the major phosphorus containing substances in Avena sativa during the first 8 days of dark germination. The endosperm, roots, and shoots were analyzed separately for acid soluble-P, phytic acid-P, inorganic-P, lipid-P, nucleic acid-P, and protein-P. Phytic acid-P comprised 53% of the total seed phosphate, while the sum of lipid-P, nucleic acid-P ...

The two nucleic acid-dependent nucleoside triphosphate phosphohydrolases, previously purified from vaccinia virus cores, were shown to be immunologically distinct enzymes. Antiserum prepared against purified phosphohydrolase I and antiserum prepared against purified phosphohydrolase II only neutralized the activity of that enzyme used as antigen. Both enzymes were induced in HeLa cells after va...

introduction: p. aeruginosa is an important multi-drug resistant (mdr) opportunistic pathogen in hospital-acquired infections. several methods based on dna analysis have been used for investigating genetic diversity of p. aeruginosa isolates. among them, rep‑pcr typing has been introduced as a rapid, low cost method with high discriminatory power. the aims of this study were to investigate geno...

conclusions nucleic acid amplification tests (naats) are very appropriate in detection of infected individuals. detection techniques such as naats are independent of bacterial viability, and have a potential to limit false negative samples, therefore, in our country, the application of different laboratory diagnosis methods including naats with culture as gold standard for determination antimic...

This is the fourteenth of a series of Biochemical Society Symposia published annually. There has been an unfortunate delay in publication since the Symposium was held on February 18, 1956 and the book was not published until May 22, 1957. A brief historical introduction to the morning session by N. W. Pirie touches on a variety of subjects from the unfounded assumptions made in nucleic acid res...
