objective(s):the aim of this study was to evaluate the oxidative status and dna integrity in testes of wistar rat offspring exposed to omega-9 monounsaturated (mufa) at different times of late organogenesis. materials and methods:sixty female rats were divided into six groups of 10 animals. the first group served as control and received the drug vehicle, olive oil (1 ml/kg/day). the second, thi...

Maize RNA polymerase utilizes heated deoxyribonucleic acid more effectively than native deoxyribonucleic acid as a template for ribonucleic acid synthesis. A ribonucleic acid-deoxyribonucleic acid hybrid accumulates in the presence of heated deoxyribonucleic acid. The amount of product formed with either native or heat-denatured deoxyribonucleic acid does not exceed the amount of deoxyribonucle...

When Escherichia coli are grown in the presence of 5-fluorouracil, the 5-fluorouracil is incorporated almost exclusively into ribonucleic acid as fluorouridylate. In this study, small but detectable amounts were incorporated into ribonucleic acid as fluorocytidylate and into deoxyribonucleic acid as fluorodeoxyuridylate and fluorodeoxycytidylate. The amount of 5-fluorouracil found in deoxyribon...

graves’ disease is an autoimmune disorder characterized by presence of antibodies directed against thyroid stimulating hormone (tsh) receptor or nearby region. other serological abnormalities like antibodies to double stranded dna (ds–dna) and antinuclear antibodies (ana) have also been observed. we studied antibodies to ds-dna and ana in our patients with graves’ disease and compared them with...

the aim of this paper is to improve the performance of the conventional goertzel algorithm in determining the protein codingregions in deoxyribonucleic acid (dna) sequences. first, the symbolic dna sequences are converted into numerical signals usingelectron ion interaction potential method. then by combining the modified anti-notch filter and linear predictive coding model,we proposed an effic...

The rate of nitrous acid deamination of labeled cytosine residues in native Escherichia coli deoxyribonucleic acid was monitored in vitro by release of acidsoluble counts after treatment with uracil deoxyribonucleic acid glycosylase. The reaction exhibited a lag and was not stimulated by several agents previously shown to enhance base substitution mutagenesis during nitrous acid treatment of du...
