Objective: Nonalcoholic steatohepatitis (NASH) is a common cause of liver disease. Although usually indolent, this disease can progress to cirrhosis in some patients. There is currently no proven medical for the results of NASH. The aim of our study was to evaluate the efficacy of combination α-tocopherol (vitamin E) and vitamin C in reducing histologic inflammation and fibrosis.

OBJECTIVES: Our objective was to prospectively examine the relation between vitamin C intake and risk of coronary heart disease (CHD) in women.

BACKGROUND: Results from prospective investigations of the relation between vitamin C intake and risk of CHD have been inconsistent. The lack of clear evidence for a protective association despite a plausible mechanism indicates the need to evaluate further the association between vitamin C intake and risk of CHD.

Vitamin C is an antioxidant and inhibitor of carcinogenic N-nitroso compound production in the stomach. Higher dietary vitamin C consumption is associated with decreased risk of gastric cancer (GC) in numerous case–control studies, but data from prospective studies are limited, particularly so for blood measures of vitamin C. The objective of this study was to determine the association of plasma and dietary vitamin C levels with the risk of GC in a case–control study nested within the European Prospective Investigation into Cancer and Nutrition (EPIC),

Objective We investigated the effects of vitamin E and C supplementation on the fatty acid composition of mononuclear cells and on the clinical observations in patients who had chronic hepatitis C and received interferon-α-2b (IFN-α-2b) and ribavirin combination .

Methods Patients were randomly allocated to receive daily 500 mg of vitamin E and 750 mg of vitamin C (vitamin group,

Dietary intake, especially of antioxidant vitamins A, C, E, and the carotenoids, has been linked with the presence and severity of asthma. From the Third National Health and Nutrition Examination Survey (NHANES III), conducted in the United States between 1988 and 1994, the authors selected 4,093 children (aged 6-17 years) for whom relevant medical, socioeconomic,

Selenium is of fundamental importance to human health. It is an essential component of several major metabolic pathways, including thyroid hormone metabolism, antioxidant defence systems, and immune function. The decline in blood selenium concentration in the UK and other European Union countries has therefore several potential public health implications, particularly in relation to the chronic disease prevalence of the Western world such as cancer and cardiovascular disease.

Background: Dietary selenium intakes in many countries, including the United Kingdom, are lower than international recommendations. No functional consequences of these lower intakes have been recognized, although experimental studies suggest that they might contribute to reduced immune function, increased cancer incidence, and increased susceptibility to viral disease.

Objective: The objective was to assess whether administration of small selenium supplements to otherwise healthy UK subjects leads to functional changes in immune status and the rates of clearance and mutation of a picornavirus: live attenuated polio vaccine.

Objective: Sepsis is associated with an increase in reactive oxygen species and low endogenous antioxidative capacity. We postulated that high-dose supplementation of sodium-selenite would improve the outcome of patients with severe sepsis and septic shock.

Design: Prospective randomized, placebo-controlled, multiple-center trial.

Setting: Eleven intensive care units in Germany.

Se is an unusual trace element in having its own codon in mRNA that specifies its insertion into selenoproteins as selenocysteine (SeCys), by means of a mechanism requiring a large SeCys-insertion complex. This exacting insertion machinery for selenoprotein production has implications for the Se requirements for cancer prevention. If Se may protect against cancer, an adequate intake of Se is desirable.

Background: We previously reported an inverse association between prediagnostic serum selenium concentrations and the risk of oesophageal squamous cell carcinoma (ESCC) and gastric cardia cancer (GCC) but not gastric noncardia cancer (GNCC) in a nested study from the Nutrition Intervention Trial in Linxian, China.

Objective: We examined the relation between baseline serum selenium and the subsequent risk of death from ESCC,
