background: exposure to ionizing radiation results in genotoxicity and the unrepaired lesions in cellular dna results in cell cycle arrest, reproductive death, interphase death, division delay, chromosome aberrations, mutations, etc. leading to the intensive destruction of cells and violation of their proliferative capacity there by adversely affecting the mammalian system. since ionizing radia...

ascorbic acid (vitamin c) supplementation has been documented as a useful tool to improve the performance of laying birds reared under harsh environmental conditions. however, there is limited information on the use of ascorbic acid as a means of ameliorating the stressful conditions imposed by feed restriction. to this effect a 3 × 2 factorial experiment was carried out to evaluate the effect ...

green tea extract has plenty of antioxidant. due to the toxicity of synthetic antioxidants, it is necessary that these antioxidants in products such as donuts be replaced with natural antioxidants. the purpose of this research is to reduce the usage of synthetic antioxidants as it is possible. so the extract was extracted and it was used as a natural antioxidant in the dough of donuts. due to t...

Amorphophallus commutatus ( Araceae) a rare cormous herb endemic to western ghats has been used by the tribes of sitamata wild life sanctuary, Rajasthan, India and tribes living in the Western Ghats, India for various ailments. The current study was carried out with an objective to investigate the enzymatic and non enzymatic contents of the tuber and leaves of the plant adopting eight enzymatic...

Lipid peroxidation is the oxidative deterioration of polyunsaturated fatty acids (PUFAs), which is a free radical related process. Studies showed that reactive oxygen species (ROS) are involved in a diversity of biological phenomena including atherosclerosis, neurodegenerative diseases, carcinogenesis etc. ROS and other pro-oxidant agents have the capacity to exhibit oxidative decomposition of ...

The aim of this study was to compare the yield and fruit quality characteristics raspberry (Rubus idaeus L.) cultivar ʽMeeker' grown in organic conventional cultivation systems. total soluble solids, titratable acidity, ascorbic acid content, phenolic flavonoid contents antioxidant capacity fruits were assessed. analyses showed that yields per cane significantly higher system. In contrast, from...

L-Ascorbic acid (vitamin C) is as essential to plants as it is to animals. Ascorbic acid functions as a major redox buffer and as a cofactor for enzymes involved in regulating photosynthesis, hormone biosynthesis, and regenerating other antioxidants. Ascorbic acid regulates cell division and growth and is involved in signal transduction. In contrast to the single pathway responsible for ascorbi...

Otsuka, Eri, Akira Yamaguchi, Shigehisa Hirose, and Hiromi Hagiwara. Characterization of osteoblastic differentiation of stromal cell line ST2 that is induced by ascorbic acid. Am. J. Physiol. 277 (Cell Physiol. 46): C132–C138, 1999.—The stromal cell line ST2, derived from mouse bone marrow, differentiated into osteoblast-like cells in response to ascorbic acid. Ascorbic acid induced alkaline p...

We evaluated the antioxidant activity and anti-wrinkle effects of Aceriphyllum rossii leaf ethanol extract (ARLEE) in vitro using human dermal fibroblasts. The total polyphenol and flavonoid contents of ARLEE were 578.6 and 206.3 mg/g, respectively. At a concentration of 250 μg/mL, the electron-donating ability of ARLEE was 87.1%. In comparison with the vehicle, ARLEE treatment at 100 μg/mL sig...
