We investigated the nucleotide composition of five genes, Xdh, Adh, Sod, Per, and 28SrRNA, in nine species of Drosophila (subgenus Sophophora) and one of Scaptodrosophila. The six species of the Drosophila saltans group markedly differ from the others in GC content and codon use bias. The GC content in the third codon position, and to a lesser extent in the first position and the introns, is hi...

Our objective was to examine the effect of orange juice and hesperetin on serum total antioxidant capacity (TAC), lipid peroxidation (MDA), uric acid and hepatic xanthine oxidase (XO) and xanthine dehydrogenase (XDH) activity in hyperuricemic rats. Experimentally hyperuricemia in rats was induced by intraperitoneal injection of potassium oxonate (250 mg/kg). Orange juice (5 ml/kg) and hespereti...

BACKGROUND Hypouricemia is caused by various diseases and disorders, such as hepatic failure, Fanconi renotubular syndrome, nutritional deficiencies and genetic defects. Genetic defects of the molybdoflavoprotein enzymes induce hypouricemia and xanthinuria. Here, we identified a patient whose plasma and urine uric acid levels were both extremely low and aimed to identify the pathogenic gene and...

The xanthine oxidoreductase (XOR) system which consists of xanthine dehydrogenase (XDH) and xathine oxidase (XO), is one of the major sources of free radicals in biological systems. The XOR system is pre-dominantly present as XDH in normal tissues and converts into the free radical generating XO-form in the damaged tissue. Therefore, the XO-form of the XOR system is expected to be mainly found ...

In the present study, we have shown that a downstream element located in the coding region of the TATA-less rat xanthine dehydrogenase/oxidase (XDH/XO) gene (-7 to +42) plays an important role in transcription initiation and C/EBP transcriptional activation. Previous work from our laboratory has shown that the promoter is organized with multiple initiator elements (Inr 1, 2, 3 and 4) which are ...

The capacity to detect nonrandom associations between restriction-map variants was examined in eight gene regions of Drosophila melanogaster (yellow-achaetescute, white, Zw, Adh, Est6, and rosy) and D. pseudoobscura (Adh and Xdh), on the basis of published population data. The statistical power from individual pairwise tests was both heterogeneous and generally low across gene regions. Sample s...

Background:  The development of nanotechnology has been a boon to mankind as its significance paved the way for several applications in therapeutics. This study was to evaluate the anti-arthritic capability of nano Selenium-lovastatin mixture (Lov-Se) against inflammatory cascade in arthritic irradiated rats. Materials and Methods: Animal model of Arthritis was organized by subcutaneous in...
