The effect of the chronic use of combined oral contraceptives (OCs) on the "activity coefficients" (alpha = coenzyme-stimulated activity/basal activity) of erythrocytic glutathione reductase and aspartate aminotransferase was studied in 2 groups of 90 female volunteers each; 1 of the groups, from
Primary open-angle glaucoma (POAG) is a complex chronic neurological disease that can result in blindness. The goal of understanding the aetiology of POAG is to be able to target effective treatment to individuals who will eventually go blind without it. Epidemiological studies of POAG have not
The erythrocyte apoenzyme activities of transketolase, glutathione reductase, and glutamic-pyruvic transaminase were determined in 236 pregnant women during the first or second trimester and again during the third trimester. There were no differences in erythrocyte glutathione reductase and
The purpose of the study was to determine how multi-vitamin deficiency affects xenobiotic-metabolizing enzyme (XME) activities in the rat liver. Vitamin levels and XME activities were studied in the livers of male Wistar rats who were fed for 4 weeks with semi-synthetic diets containing either
The activity of the red blood cell enzymes transketolase, glutathione reductase, and aspartate transaminase, and their activation by the coenzymes thiamine, riboflavin, and pyridoxine, the pyruvate tolerance test, the leucocyte vitamin C concentration, and the activity in serum of gamma-glutamyl
Necessity of dietary vitamin B6 to the biopotency of selenium (Se) for the levels of Se and glutathione peroxidase (GSH-Px) in tissues was investigated. Male Wistar 12-week-old rats were fed a vitamin B6-Se-deficient basal diet for 3 weeks, and then the rats were divided into 6 groups. One group was
The impact of heart failure and its treatment on specific nutrient requirements is unknown. Furthermore, depletion of water-soluble B vitamins that play key roles in the production of cellular energy in patients with heart failure can contribute to depletion of energy reserves observed in the
Deficiency of various vitamins in postnatally developing chick during chromium intoxication and their recovery during vitamins (B and E) and glutathione therapies has been investigated. Study was concentrated on liver, kidney, muscles and serum. Newly hatched chicks were reared in laboratory. They
Folate deprivation induces neurotoxicity that is potentiated by additional nutritional and genetic deficiencies including vitamin E and apolipoprotein E deficiency. These deficiencies collectively induce oxidative damage, cognitive impairment, and compensatory alteration in glutathione generation.
BACKGROUND
This study examined the status of oxidative stress and B vitamins in hepatocellular carcinoma (HCC) patients in different tumor-node-metastasis stages. Patients were divided into two groups as I + II (n = 21) and III + IV (n = 19).
METHODS
Plasma levels of lipid oxidation,
Folate could have an antioxidant role but also may be detrimental under vitamin B12 deficiency. The aim was to investigate the effect of different dietary folic acid (FA) levels, on oxidative stress in B12 induced deficient aged rats. Thirty-five male aged Sprague-Dawley rats,
Our previous report demonstrated that, when vitamin deficiency is associated with high contents of long chain polyunsaturated fatty acids (LCPUFA) n3, lipid peroxidation susceptibility in rat heart and liver increases. In this paper, we evaluated the effect of the same dietary administration on
OBJECTIVE
This study aimed to evaluate the status of several vitamins and to investigate the effect of regular individual supplementation on their status in this population.
METHODS
An observational study.
METHODS
State of Burgenland, Austria.
METHODS
A total of 102 non-institutionalized subjects
Homocysteine levels are affected by diet factors such as vitamin deficiencies, non-diet factors such as genetic disorders, and stress exposure. Hyperhomocysteinemia has been implicated in several disorders, including cardiovascular disease, depression, schizophrenia, Alzheimer's and Parkinson's
Vitamin status was assessed in 26 recently institutionalized elderly subjects by combining dietary and biochemical measurements of thiamin, riboflavin, niacin, beta-carotene, vitamins C, A, D and E at admission (P1), and 1.5 (P2), 3.0 (P3), 4.5 (P4), 6.0 (P5), 12 (P6) months later. At admission,
