The purpose of this study was to determine the relationship between the overall
changes in concentration of plasma pyridoxal 5'-phosphate (PLP), red blood cell PLP (rbc
PLP) and plasma glucose during an oral glucose tolerance test (OGTT) in persons with
diabetes mellitus (DM), and to test the hypothesis that the...
Previous studies suggest that vitamin B-6 supplementation can alter fuel metabolism during
exercise and plasma amino acid levels at rest. To examine the effect of vitamin B-6
supplementation on plasma fuel substrates and amino acid levels during exercise, five trained
males (age: 29±7; V0₂ max: 54.7±6.2 ml/kg/min) performed two separate...
The aim of this study was to investigate the vitamin B-6 status of Saudi adult males and compare the status between rural and urban subjects. Fifty-one adult male subjects were recruited from urban (n=31) and rural (n=20) populations of Riyadh. These subjects were reclassified to cigarette smokers (n=19), water pipe...
Two studies were conducted to determine the effect of varying vitamin B-6 (B- 6) status on lymphocyte mitogenic response and pyridoxal 5'-phosphate (PLP) concentration in peripheral blood mononuclear cells (PBMC) in young women. In the first study, women were fed 1 mg/d for the first week and 1.5, 2.1 and...
The purpose of this study was to examine the effect of extreme exercise on vitamin B-6
metabolism and urea nitrogen. Nine men and five women completed two 5-day trials; Trial 1
(T1) included a 50-km ultramarathon on day 4 and during Trial 2 (T2) subjects were "inactive"
on day 4....
