The addition of antioxidants is one of the strategies to inhibit lipid oxidation, a major cause of lipid deterioration in foods leading to rancidity development and nutritional losses. However, several studies have... been reported that conventional antioxidant assays, e.g., TPC, ABTS, FRAP, and ORAC could not predict antioxidant performance in several foods. This study aimed to investigate the performance of two recently developed assays, e.g., the conjugatedPublication Metadata only Apolar Radical Initiated Conjugated Autoxidizable Triene (ApoCAT) Assay: Effects of Oxidant Locations on Antioxidant Capacities and Interactions(2015-09-02) Atikorn Panya; Waranya Temthawee; Natthaporn Phonsatta; Danai Charoensuk; Pawinee Deetae; Wonnop Visessanguan; Eric A. Decker; Thailand National Center for Genetic Engineering and Biotechnology; Mahidol University; University of Massachusetts; King Abdulaziz University© 2015 American Chemical Society. Development of an antioxidant assay explaining antioxidant behaviors in complex food systems has been a challenging topic for food scientists. This research aimed to investigate antioxidant capacities... and interactions of selected synthetic antioxidants and commercial natural antioxidant extracts using the CAT assay and a newly developed ApoCAT assay, which used water- and lipid-soluble azo radical initiators, respectively. Results suggested that the higherPublication Metadata only Antioxidant therapies for thalassemia(2014-07-01) Ruchaneekorn W. Kalpravidh; Suneerat Hatairaktham; Mahidol University© 2014 Nova Science Publishers, Inc. The cellular redox status in physiological condition is normally well-balanced between oxidant and antioxidant levels. Oxidative stress is defined as the disturbance state that the production of the oxidants... is greater than the efficiency of the antioxidant system. In the pathogenesis of thalassemia, redox-active iron released from excess unpaired globin chains causes oxidative damage to the membrane of mature or immature red blood cells. This leads to increasedItem Metadata only Antioxidants and antioxidant activities of pigmented rice varieties and rice bran(Mahidol University. Mahidol University Library and Knowledge Center, 2007) Phenphan Chanphrom; Pongtorn SungpuagItem Metadata only Beta Glucan, Antioxidants and selected nutrients in wild mushrooms from Thailand.(2011) Chanida Hansawasdi; Ponthipa Meepayung; Nanteethip Limpeanchob; Jaruntorn Boonyanuphap; Harry J Wichers; Mahidol University International College. Science Division.glucan (a modulator of the immune system), nutraceutical properties and other medicinal qualities with antioxidant activities. This study explores the interspecific differences in health beneficial functions of various species of wild mushrooms collected....)

The antioxidants, phenolicsItem Metadata only Antioxidant activity and protective effects of Gymnema Inodorum decne. on red blood cell hemolysis and DNA damage in TK6 human lymphoblastoid cells(Mahidol University. Mahidol University Library and Knowledge Center, 2005) Thanyaluk Muangman; Nalinee Chongviriyaphan; Noppawan Phumala; Chada Pisalphong; Prapaipat Klungsupya; Pongtorn Sungpuag; Umaporn SuthutvoravutEpidemiological evidence indicates that diets high in fruits and vegetables are rich in many antioxidant nutrients, having capability of decreasing the risk of chronic degenerative diseases. The pathogenesis of these diseases is hypothesized... to be the harmful effects of free radicals on DNA, protein, lipid, and small intracellular molecules. Recently, the search for natural antioxidants and other preparations of plants concerning the beneficial effect for good health has been intensified. Still, littlePublication Metadata only Antioxidant Activity and Induction of mRNA Expressions of Antioxidant Enzymes in HEK-293 Cells of Moringa oleifera Leaf Extract(2015-07-10) Boonyadist Vongsak; Supachoke Mangmool; Wandee Gritsanapan; Mahidol University© Georg Thieme Verlag KG Stuttgart, New York. The leaves of Moringa oleifera, collected in different provinces in Thailand, were determined for the contents of total phenolics, total flavonoids, major components, and antioxidant activity.... The extract and its major active components were investigated for the inhibition of H2O2-induced reactive oxygen species production and the effects on antioxidant enzymes mRNA expression. The extract, crypto-chlorogenic acid, isoquercetin and astragalinItem Metadata only Phytochemistry and antioxidant activity of Pluchea Indica(Mahidol University. Mahidol University Library and Knowledge Center, 2005) Anchalee Traithip; Aimon SomanabandhuPublication Metadata only Determination of the effects of adding milk and sugar on the antioxidant capacity of oolong tea by chemical and cell culture-based antioxidant assays(2015-01-01) Angkana Wipatanawin; Sudarat Phongsawanit; Thadthanan Maneeratprasert; Sittiwat Lertsiri; Pawinee Deetae; Chiang Mai University; Mahidol University© 2015 Chiang Mai University. All rights reserved. The effect of sugars and/or milk on the antioxidant capacity of Oolong tea was evaluated using 2,2′-azino-bis 3-ethylbenzothiazoline-6-sulfonic acid diammonium salt (ABTS), ferrous ion-chelating... (FIC) and cellular antioxidant activity (CAA) assays. The addition of sugar did not alter the antioxidant capacity of tea (p < 0.05), however with the addition of sweetener an 18% and 14% increase was observed using ABTS and FIC assays respectivelyItem Metadata only Antioxidant status and tissue damage in [beta]-thalassemia/hemoglobin E(Mahidol University.
