d alpha tocopherol/inflammation

OBJECTIVE In this clinical trial we studied whether oral supplementation with D-alpha-tocopherol (alpha-Toc), L-ascorbic acid (Asc), or alpha-Toc combined with Asc influenced the solar simulated radiation (SSR) induced skin inflammation in healthy volunteers. METHODS We investigated the following

We analyzed the role of oxidative stress on liver collagen gene expression in vivo. Long- and short-term supplementation with the lipophilic antioxidant D-alpha-tocopherol (40 IU/day for 8 wk or 450 IU for 48 h) to normal C57BL/6 mice selectively decreased liver collagen mRNA by approximately 70 and

OBJECTIVE Oxidative stress mediates activation and stimulates collagen production of cultured hepatic stellate (Ito) cells. The aim of this study was to assess whether oxidative stress contributes to hepatic fibrogenesis in chronic hepatitis C. METHODS In liver biopsy specimens of patients with

This study was conducted to evaluate the potential benefit of particle reduction down to nanoscale on curcumin, a unique natural active compound facing therapeutic problems due to low solubility and permeability. In addition, the presence of TPGS as a surfactant for multiple functions on curcumin

OBJECTIVE To investigate the anti-oxidant and anti-neutrophil recruitment effects of rectal d-alpha (d-alpha) tocopherol administration on mild and moderately active ulcerative colitis (UC). METHODS Fifteen patients with mild and moderately active ulcerative colitis were enrolled in an open-label

Muscle atrophy commonly follows anterior cruciate ligament (ACL) injury and surgery. Proinflammatory cytokines can induce and exacerbate oxidative stress, potentiating muscle atrophy. The purpose of this study was to evaluate the influence of prior antioxidant (AO) supplementation on circulating

Reports indicate contradictory outcomes for anti-inflammatory functions of the alpha-tocopherol isoform of vitamin E in clinical studies of asthma and atherosclerosis. These seemingly disparate clinical results are consistent with novel unrecognized properties of isoforms of vitamin E reported in

To observe the effects of supplemental dietary d-α-tocopherol in relation to dietary energy on growth and immune status in dairy calves, 32 newborn Holstein bull calves were assigned to 1 of 4 treatments for 5 wk in a 2 × 2 factorial, randomized complete block, split-plot design. Calves received

The purpose of this study was to examine the effects of feeding docosahexaenoic acid (DHA) as triacylglycerol on the fatty acid composition, eicosanoid production, and select activities of human peripheral blood mononuclear cells (PBMNC). A 120-d study with 11 healthy men was conducted at the

The objective of this study was to investigate the effect of vitamin E supplementation on an experimental Haemonchus contortus infection in lambs. Twenty lambs were stratified into two treatment groups based on fecal egg count. Worm-free lambs, 28-32 weeks of age, were supplemented with vitamin E

We have recently reported that gamma-tocopherol (gammaT) reduces allergen- and zymosan-induced inflammation using rodent models. As an initial step in extending these observations to humans, we conducted an open-label, Phase I dosing study of two doses (one or two capsules daily for 1 week) of a

Inflammatory disorders of the bowel and colon cancer are associated with elevated indices of oxidative stress. Analogous elevations in markers of oxidative stress and loss of cell-membrane integrity are also observed in the colons of rats deficient in vitamin E (D-alpha-tocopherol), the major

Postmenopausal osteoporosis may be caused, in part, by oxidative stress and inflammation. Vitamin E is a strong antioxidant which has been shown to have anti-inflammatory and bone-protective effects. The objective of this study was to investigate the effects of various doses of supplemental vitamin

Background: Millions of households in the world depend on wood and biomass for cooking and heating. This dependence leads to undesirable toxic effects, such as ocular and pulmonary toxicity. Objectives: The present study examined
