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...

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...

Vitamin B-6 and pyrimidine deoxynucleoside metabolism in the rat

Creator:: Jensen, Christine May
Abstract:: Serine transhydroxymethylase (STHM), a pyridoxal 5'- phosphate requiring enzyme is indirectly involved in pyrimidine deoxynucleotide metabolism. A decrease in the activity of this enzyme could lead to altered deoxycytidine (dC) metabolism. This study was undertaken to determine if a vitamin B-6 deficiency affects dC metabolism. The effect of a vitamin...

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....

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...

Vitamin B-6 status of persons with diabetes mellitus

Creator:: Smith, Daniel E.
Abstract:: The status of vitamin B-6 (B6) nutriture of nine persons (4F;5M) with insulin dependent diabetes mellitus (IDDM), nine persons (5F;4M) with non-insulin dependent diabetes mellitus (NIDDM), and 18 control individuals (9F;9M) was evaluated, using biochemical and dietary indicators of B6 status. The biochemical indices employed were plasma concentration of pyridoxal...

Effect of varying levels of vitamin B-6 intake on lymphocyte mitogenic response and vitamin B-6 concentration in human peripheral blood mononuclear cells

Creator:: Kwak, Ho-Kyung
Abstract:: 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...

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...

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...
