Journal ArticleDOI
The ferric reducing ability of plasma (FRAP) as a measure of 'antioxidant power' : the FRAP assay
TL;DR: The FRAP assay offers a putative index of antioxidant, or reducing, potential of biological fluids within the technological reach of every laboratory and researcher interested in oxidative stress and its effects.
Journal ArticleDOI
Plant L‐ascorbic acid: chemistry, function, metabolism, bioavailability and effects of processing
Mark W. Davey,M. Van Montagu,Dirk Inzé,Maite Sanmartín,Angelos K. Kanellis,Nicholas Smirnoff,I. J. J. Benzie,John (Sean) J. Strain,D. Favell,J. Fletcher +9 more
TL;DR: The role of L-AA in metabolism and the latest studies regarding its bio- synthesis, tissue compartmentalisation, turnover and catabolism are focused on, as well as the potential to improve the L- AA content of crops.
Journal ArticleDOI
Accuracy of weighed dietary records in studies of diet and health
M. B. E. Livingstone,Andrew M. Prentice,John (Sean) J. Strain,W A Coward,Alison E. Black,Margo E. Barker,PG McKenna,Roger G. Whitehead +7 more
TL;DR: Energy intake as measured by the seven day weighed dietary record and total energy expenditure estimated concurrently by the doubly labelled water technique showed a serious bias in reporting habitual energy intake.
Journal ArticleDOI
The immune system as a physiological indicator of marginal copper status
TL;DR: A selection of immunological markers that could be considered potentially sensitive markers of marginal Cu status are evaluated, including neutrophil function, interleukin 2 production, blastogenic response to mitogens and lymphocyte subset phenotyping.
Journal ArticleDOI
Simultaneous measurement of free-living energy expenditure by the doubly labeled water method and heart-rate monitoring.
M. B. E. Livingstone,Andrew M. Prentice,W. A. Coward,S. M. Ceesay,John (Sean) J. Strain,PG McKenna,G. B. Nevin,Margo E. Barker,R. J. Hickey +8 more
TL;DR: The FLEX HR method provides a close estimation of the TEE of population groups, however, an increased number of sampling days may improve the precision of individual estimates of TEE.
