Plasma B-6 vitamer changes following a 50-km ultramarathon

Creator:: Leonard, Scott W.
Abstract:: The purpose of this study was to measure plasma B-6 vitamers, and other factors which may affect the plasma concentrations of these vitamers under extreme physical conditions. Blood samples were drawn from 8 men and 3 women (43.7 ± 8.6 years) 30 minutes prior to the start of a 50-km...

The effect of a 50-km ultramarathon on vitamin B-6 metabolism and plasma and urinary urea nitrogen

Creator:: Grediagin, Ann
Abstract:: 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....

Changes in plasma pyridoxal 5'-phosphate and red blood cell pyridoxal 5'-phosphate concentration during an oral glucose tolerance test in persons with diabetes mellitus

Creator:: Martinson, Kerry Elizabeth
Abstract:: 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...

Energy need, nutrient intake, fitness, body composition, and health risk factors in women with childhood and adult-onset obesity before and after a 9-month nutrition education and walking program

Creator:: Moore, Jane M.
Abstract:: The effect of a 9—month nutrition education and walking program on energy need, body composition, nutrient intake, nutritional status, aerobic fitness, and health risk factors was determined in 7 women with childhood—onset obesity (CO) and 8 women with adult—onset obesity (AO). Data were collected before and after the 9—month program...

The effect of two levels of glucose ingestion on plasma pyridoxal 5'-phosphate concentration

Creator:: Huang, Ying-Hui
Abstract:: This study was designed to evaluate the effect of glucose on plasma pyridoxal 5'- phosphate (PLP) concentration. The objective was to determine whether there was a negative relationship between glucose ingestion and plasma PLP concentration and to evaluate the possible mechanism of decreased PLP after acute glucose ingestion. Seven healthy...

Effect of controlled vitamin B-6 intake and pyridoxine supplementation on B-6 status of smokers

Creator:: Sindihebura-Ruhumba, Pascaline
Abstract:: Previous studies have found that smoking may have a negative effect on vitamin B-6 indices and have demonstrated a possible association between smoking and depressed plasma pyridoxal-5'-phosphate (PLP) concentration. Individuals with plasma PLP values below the adequate level of 30 nmoles/L might benefit from consumption of vitamin B-6 supplements, but...

Vitamin B6 status over time and its relation to symptoms of carpal tunnel syndrome

Creator:: Bolli, Andrea M.
Abstract:: Research suggests that, in individuals with carpal tunnel syndrome (CTS), low plasma pyridoxal 5'-phosphate (PLP) concentrations are related to an increased incidence and severity of symptoms associated with CTS. This study was designed to determine the relationship between plasma and red blood cell PLP concentrations and the severity and incidence...

The effect of exhaustive endurance exercise and vitamin B-6 supplementation on vitamin B-6 metabolism and growth hormone in men

Creator:: Dunton, Nancy J.
Abstract:: Trained male cyclists (6 in study 1, 5 in study 2) cycled to exhaustion (EXH) at 75% of VO₂ max twice; once in the non-supplemented (NS) state and once in the vitamin B-6 (B-6)(20 mg PN) supplemented (S) state. The diet contained 2.3 mg B-6 in study 1 and 1.9...

Effect of vitamin B-6 intake, protein intake and bioavailability on vitamin B-6 status for women

Creator:: Hansen, Christine M., 1953-
Abstract:: Four studies were conducted to evaluate the effect of varying levels of vitamin B-6 (B6), protein and pyridoxine glucoside (PNG) on B6 status and requirements of women. In the first two studies, women were fed a constant protein diet and vitamin B-6 intakes of 0.84 to 2.39 mg/d during 10-...

Evaluation of vitamin B-6 status of Saudi adult males in the Riyadh region - Saudi Arabia

Creator:: Al-Assaf, Abdullah
Abstract:: 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...
