Journal ArticleDOI
An automated, specific, spectrophotometric method for measuring ascorbic acid in plasma (EFTSA)
TL;DR: EFTSA appears suitable for the routine measurement of ascorbic acid in plasma and there is no interference by dehydroascorbic acid when readings are taken within a 15-60-s reaction time window.
Journal ArticleDOI
Effect of Panax ginseng supplementation on biomarkers of glucose tolerance, antioxidant status and oxidative stress in type 2 diabetic subjects: results of a placebo-controlled human intervention trial
Shuk-Woon Ma,Iris F.F. Benzie,Tanya T W Chu,Benny S. P. Fok,Brian Tomlinson,L. A. H. Critchley +5 more
TL;DR: This study investigated the effect of supplementation with P. ginseng on type 2 diabetic subjects in relation to glycaemic control and cardiovascular risk, and the effects on biomarkers of oxidative stress and antioxidant defence were also studied.
Journal ArticleDOI
Enhanced bioavailability of zeaxanthin in a milk-based formulation of wolfberry (Gou Qi Zi; Fructus barbarum L.).
TL;DR: Results showed clearly that homogenisation of wolfberry in hot skimmed milk results in a formulation that has a 3-fold enhanced bioavailability of zeaxanthin compared with both the ‘classical’ hot water and warm skimmed Milk treatment of the berries.
Journal ArticleDOI
Ganoderma lucidum ('Lingzhi'); acute and short-term biomarker response to supplementation
TL;DR: The pattern of biomarker response after supplementation indicated possible benefit in terms of antioxidant status and CHD risk, but further study is needed to elucidate the nature and longer-term effects of the absorbable antioxidants from Lingzhi.
Journal ArticleDOI
Effects of dietary antioxidants on DNA damage in lysed cells using a modified comet assay procedure
TL;DR: It is suggested that, used in conjunction with the standard comet assay, this lysed-cell version is useful for assessing the effect of the cell membrane and intracellular systems on susceptibility of DNA to oxidative damage, and will help determine the mechanism of protection or damage by phytochemicals.
