Degradation of nucleic acids with ozone. I. Degradation of nucleobases,ribonucleosides and ribonucleoside-5'-monophosphates.

Degradation of nucleic acids in the rumen.

I . Nucleic acids introduced into the rumens of calves, or incubated with calf, sheep or cow rumen contents in vitro, were rapidly destroyed. 2. The degradation products formed were separated and identified by means of column chromatography on Sephadex G-10 Dextran gel and thin-layer chromatography on cellulose. 3. In vitro, RXA was rapidly (within I h) converted into ultrafilterable oligo-and ...

degradation of oil impregnated paper insulation under influence of repetitive fast high voltage impulses

در طی سالهای اخیراستفاده ازمنابع انرژی تجدید پذیر در شبکه های مدرن بنا به دلایل زیست محیطی و اقتصادی به طور گسترده استفاده شده است همچون نیروگاههای بادی و خورشیدی .ولتاژتولیدی این نیروگاهها اغلب به فرم dc می باشد وادوات الکترونیک قدرت به عنوان مبدل و پل بین شکل موج dc وac استفاده می شوند.این پروسه باعث ایجاد پالسهایی برروی شکل موج خروجی می شود که می تواند وارد تجهیزات قدرت همچون ترانسفورماتور ی...

Degradation of naphthalenesulfonic acids by oxidation with ozone in aqueous phase

Sulfonic aromatic compounds are widely used in the textile industry for the synthesis of azo dyes. The presence of the sulfonic group endows these compounds with high water-solubility and resistance to biological treatment. The present work analysed the efficacy of oxidation with ozone in the treatment of waters containing naphthalene-1-sulfonic acid, naphthalene-1,5-disulfonic acid and naphtha...

Ozone Degradation of Iodinated Pharmaceutical Compounds

Degradation of nucleic acids by lysosomal extracts of rat liver and Ehrlich ascites tumor cells.

The ability of rat liver lysosomes and Ehrlich ascites tumor lysosomes to degrade nucleic acids has been studied. Extracts of rat liver tritosomes and of tumor cell mitochondrial plus lysosomal fractions were incubated with various types of DNA and RNA from sources ranging from bacteria to mammals. The extracts were able to hydrolyze all the nucleic acids completely to free nucleosides and inor...
