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...

Determination of vitamin B-6 and pyridoxine-glucoside in selected Malawi foods and the effect of preparation techniques on vitamin B-6 and pyridoxine-glucoside content

Creator:: Kaunda, Jean R.
Abstract:: There were two main purposes to this study. The first was to determine the vitamin B-6 and pyridoxine β-glucoside content of selected foods commonly consumed in Malawi. The second was to examine the effect of preparation procedures of foods in Malawi on the content of vitamin B-6 and pyridoxine β-...

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...

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...

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...

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 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...

Effect of vitamin B-6 status on fatty acid and lipid metabolism in women

Creator:: Kim, Min Sun, 1971-
Abstract:: The effect of vitamin B-6 (B-6) status on plasma fatty acids (FA) levels and lipid metabolism was investigated in this metabolic study. Eight female subjects were fed for 28 days. For the first 7 days, they were fed a constant diet containing 2.10 mg of B-6. For the rest of...

Supplemental vitamin B-6 and endurance exercise effects on plasma catecholamines of trained male cyclists

Creator:: Young, Jennifer Charity
Abstract:: This study examined the effect of vitamin B-6 supplementation and exhaustive submaximal exercise on plasma catecholamine concentrations, and the relationship between plasma catecholamines and fuel use, heart rate and oxygen consumption. Five trained men (age= 18-35 years; V0₂max=53 ml 0₂/kg/min.) participated in two controlled dietary periods that were identical except...
