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...
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...
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...
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...
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 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 purposes of the research presented in this thesis were
to: (l) assess the nutritional status of vegetarian and nonvegetarian
Seventh-day Adventists (SDA), non-SDA non-vegetarians,
and non-vegetarian hormone dependent cancer subjects; (2) determine
the relationship of various blood and urinary biochemical
parameters to dietary intake; (3) determine hormonal status in...
