alpha tocopherol/inflammation

Activation of the resident macrophage populations of the reticuloendothelial system is a key component of the complex pathophysiology of sepsis. Macrophage activation leads to production and secretion of inflammatory mediators such as cytokines, vasoactive substances, free radicals, and chemokines,

The diabetic state confers an increased propensity to accelerated atherogenesis. In addition to the established risk factors, there is evidence for increased oxidative stress and inflammation in diabetes. Increased oxidative stress is manifested by increased lipid peroxidation (e.g. increased

BACKGROUND Despite evidence of antioxidant effects of vitamin E in vitro and in animal studies, large, randomized clinical trials have not substantiated a benefit of vitamin E in reducing inflammation in humans. An individual's genetic background may affect the response to α-tocopherol

Minter, B.E. et al. recently published an article titled "Differential Effects of MitoVitE, α-Tocopherol and Trolox on Oxidative Stress, Mitochondrial Function and Inflammatory Signalling Pathways in Endothelial Cells Cultured under Conditions Mimicking Sepsis" [1][...].

BACKGROUND Currently, tissue damage induced by cobalt nanoparticles (CoNPs) and cobalt ions (Co2+) are the most serious adverse effect in the patients with metal-on-metal hip prostheses. Therefore, an urgent need exists for the identification of the mechanisms and the development of therapeutic

This study was conducted to determine if alpha-tocopherol facilitates recovery from lipopolysaccharide (LPS)-induced sickness behavior through a NFkappaB-dependent mechanism. In the first study, 3 daily intraperitoneal (i.p.) injections of alpha-tocopherol (20 mg) improved recovery from sickness

The anti-inflammatory effects of two esters of a-tocopherol (α-TOH), all-rac-α-TOH acetate (DL-α-TOA) and RRR-α-TOH succinate (D-α-TOS), on broilers repeatedly challenged with lipopolysaccharide (LPS) were investigated. Three hundred and twenty 1-d-old broiler chicks were allotted into four

Intrapulmonary administration of bacterial lipopolysaccharide (LPS) induces a well-characterized lung inflammatory response involving alveolar macrophage activation, proinflammatory cytokine elaboration, and neutrophil influx. Vitamin E, a lipophilic antioxidant consisting of a family that includes

OBJECTIVE The purpose of this study was to investigate the dose-dependent effects of RRR-alpha-tocopherol supplementation in coronary heart disease (CHD) patients and healthy subjects on plasma alpha-tocopherol levels, plasma lipoprotein distribution, LDL oxidation, and inflammatory plasma

Cancer development and progression are closely associated with inflammation. NF-κB (nuclear factor κB) provides a mechanistic link between inflammation and cancer, and is a major factor controlling the ability of malignant cells to resist tumour surveillance mechanisms. NF-κB might also regulate

Immunoglobulin G4 (IgG4)-related disease is a distinct group of disorders that are characterised by intense infiltration of an organ with IgG4(+) cells, subsequent inflammation, fibrosis, and masses. We report a new treatment of orbital IgG4-related disease with pentoxyphylline and α-tocopherol,

Inflammatory and oxidative stresses play a pivotal role in atherogenesis. Vitamin E and vitamin C are the two most important dietary antioxidants; moreover, vitamin E has anti-inflammatory effects. Combined supplementations with vitamin E and vitamin C twice daily for 3 y reduced lipid peroxidation

1. We have determined the antioxidant status of synovial fluid and serum of patients with inflammatory joint disease in terms of the biologically active lipid-soluble antioxidant, alpha-tocopherol. Synovial fluid concentrations of alpha-tocopherol were significantly lower relative to those of paired

OBJECTIVE Short-term cigarette smoke (CS) exposure leads to acute lung inflammation through its influence over oxidants/antioxidants imbalance. Antioxidant vitamins such as ascorbic acid and alpha-tocopherol interact with oxidizing radicals. It is not clear if antioxidant supplementation can reduce
