Five types of caneberries [evergreen blackberries (Rubus laciniatus), marionberries (Rubus ursinus), boysenberries (Rubus ursinus x idaeus), red raspberries (Rubus idaeus), and black raspberries (Rubus occidentalis)] were analyzed for antioxidant activity by measuring their oxygen radical absorbance
Twelve Sambucus nigra subsp. canadensis genotypes were grown at two Missouri and one Oregon (USA) locations to characterize fruit composition in 2004, 2005, and 2006. Fruit was also sampled from an additional 10 genotypes of subsp. canadensis and nigra grown in Oregon. Soluble solids content ranged
The effluents from textile dyeing industry are causing water pollution and may transform into more toxic and carcinogenic chemical species by environmental conditions. Therefore systemic toxicity of textile dyes is major health concern. Hence, this study sought to examine the toxic effect of
Natural antioxidants, free radical scavengers as catalase, glutathione reductase and glutathione are considered for aging mechanism. The objective of our study was to investigate the differences in the life span of male Oregon (w.t.) and vestigial Drosophila melanogaster, the possible role of free
Enhanced levels of antioxidants, phenolic compounds, carotenoids and vitamin C have been reported for several crops grown under organic fertilizer, albeit with yield penalties. As organic agricultural practices continue to grow and find favor it is critical to gain an understanding of the molecular
The effect of water-soluble synthetic antioxidant TS-13 (sodium 3-(3'-tert-butyl-4'-hydroxyphenyl) propyl thiosulfonate) on life span of different lines of Drosophila melanogaster under normal conditions and survival under oxidative stress induced by hydrogen peroxide and paraquat has been
The effects of hydrophilic synthetic antioxidant TC-13 sodium (3'-(3'-tert-butyl-4'-hydroxyphenyl)propylthiosulfonate on survival of various strains of Drosophila melanogaster were studied under conditions of oxidative stress induced with H(2)O(2)and paraquat. In a concentration of 1%, TC-13
Drosophila melanogaster adults of the Oregon R and Canton S wild-type stocks were fed for 24 h with 0.10 M, 0.25 M and 0.50 M MgCl2 in 1 per cent sugar solution. This treatment resulted in a significant increase (10-50 per cent) in the activities of the enzymes superoxide dismutase (SOD) and
The effect of hydrophilic synthetic antioxidant TC-13 (3-(3'-tert-butyl-4'-hydroxyphenyl)propylthiosulfonate sodium) inducing the antioxidant-responsive element on the lifespan of Drosophila melanogaster was studied. Addition of 1% TC-13 to diets prolonged the lifespan of long-lived D. melanogaster
The total phenolic contents and antioxidant activities of garlics from California, Oregon, Washington, and New York were determined by Fourier transform infrared (FT-IR) spectroscopy (400-4000 cm(-1)). The total phenolic content was quantified [Folin-Ciocalteu assay (FC)] and three antioxidant
In this study, we aimed to investigate the mutagenic and carcinogenic potential of a volatile organic compound (VOC) mixture with references to the response of D.melanogaster using selected antioxidant gene expressions, RAPD assay and base-pair change of ribosomal 18S, and the internal transcribed
Total phenolic content (TPC) and total antioxidant capacity (TAC) of four onion varieties (red, white, yellow and sweet) and shallot from selected locations (Washington, Idaho, Oregon, Texas and Georgia) were determined using Fourier transform infrared (FT-IR) spectroscopy (4000-400cm-1).
The enzyme catalase protects aerobic organisms from oxygen free radical damage by converting hydrogen peroxide to molecular oxygen and water before it can decompose to form the highly reactive hydroxyl radical. This damage has been implicated in the increased risk of disease and death associated
Organic osmolytes, solutes that regulate cell volume, occur at high levels in marine invertebrates. These are mostly free amino acids such as taurine, which are "compatible" with cell macromolecules, and methylamines such as trimethylamine oxide, which may have a nonosmotic role as a protein
In vitro antioxidant virtue and life-prolonging effect of phycoerythrin (PE; a pigment protein isolated from Phormidium sp. A09DM) have been revealed in our previous reports (Sonani et al. in Age 36:9717, 2014a; Sonani et al. in Process Biochem 49:1757-1766, 2014b). It has been hypothesized that the
