Dapsone hydroxylamine (DDS-NOH) is a direct-acting hemolytic agent responsible for dapsone-induced hemolytic anemia in the rat. The hemolytic activity of DDS-NOH is associated with the formation of disulfide-linked hemoglobin adducts on membrane skeletal proteins. We have postulated that this membrane protein "damage" is a consequence of DDS-NOH-induced oxidative stress within the red cell and ...

In this study, use of the covalent enzyme immobilization method was proposed to attach cholesterol oxidase (ChO) on a conducting polymer, poly(3-thiopheneacetic acid), [poly(3-TPAA)]. Three red-orange poly(3-TPAA) films, named electrodes A, B and C, were electropolymerized on a platinum electrode by applying a constant current of 1.5 mA, for 5, 20 and 100 s, respectively. Further, 1-ethyl-3-(3-...

Mixed anaerobic bacterial consortia have been show to reduce azo dyes and batch decolourisation tests have also demonstrated that predominantly methanogenic cultures also perform azo bond cleavage. The anaerobic treatment of wool dyeing effluents, which contain acetic acid, could thus be improved with a better knowledge of methanogenic dye degradation. Therefore, the decolourisation of two azo ...

D&C Red No. 28 (Red 28) is a US certified color additive used in drugs and cosmetics. Little is known about the extent of systemic absorption and pharmacokinetic behavior of Red 28. Therefore, these studies were performed to determine oral bioavailability and pharmacokinetic parameters of Red 28 in male F-344 rats following single and repeated oral dosing. Rats were administered either a single...

BACKGROUND: Humic acid is a natural polymeric composition which is produced as a result of decaying organic matters in soil, peat and lignin to increase crop product. OBJECTIVES: Assessment the effect of different irrigation regime and humic acid on red bean production and correlation coefficient between measured traits. METHODS: Cu...

In total, expression levels from 6567 genes are measured for each of the 88 samples, where 63 are labeled calibration samples and 25 represent blind tests. In the analysis we used the red intensity (ri) and the relative red intensity (rri). Genes are omitted if for any of the samples ri is less than 20. With this cut we are left with 2308 genes, which are used below for the analysis. The cut in...

Using various photostationary state light sources to obtain reproducible phytochrome conversion of from 5 to 88% P(FR), assayed by 2 wavelength in vivo spectrophotometry, relationships between initial percent P(FR) and elongation of apical Avena coleoptile segments over the succeeding 20 hours in darkness were studied. With material grown in total darkness, all P(FR) levels promote elongation, ...

Transcriptome profiles of the red- and white-fleshed apples in an F1 segregating population of Malus sieversii f.Niedzwetzkyana and M.domestica 'Fuji' were generated using the next-generation high-throughput RNA sequencing (RNA-Seq) technology and compared. A total of 114 differentially expressed genes (DEGs) were obtained, of which 88 were up-regulated and 26 were down-regulated in red-fleshed...
