Dietary intake data of 15 treated patients with
phenylketonuria (PKU) (7-17 years) and six control siblings
(6-14 years) were used to evaluate the effectiveness of
medical foods to balance energy, protein, vitamin B-6, and
individual amino acids from natural foods and to evaluate
vitamin B-6 status. Four-day diet records were...
The objectives of this study were a) to determine
if pyridoxine (PN) supplementation increases the rate at
which plasma urea and ammonia return to basal levels,
following exercise, b) to determine, by open circuit
calorimetry, the utilization of carbohydrates, and c) to
further understand vitamin B-6 metabolism during and
following...
The purpose of this study was to evaluate the effectiveness
of a one-hour in-service nutrition education
workshop for high school coaches in Corvallis, Eugene and
Salem, Oregon. The objectives were to determine: 1. if
the workshop can make positive changes in nutrition knowledge;
2. which type of participant benefits most...
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...
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-...
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 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...
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...
