Vitamin d glutamin creatin

Coby van de Bool, Michael C Steiner, Annemie M W J Schols
PURPOSE OF REVIEW: This review presents current knowledge regarding the rationale and efficacy of nutrition as an ergogenic aid to enhance the effects of exercise and training in chronic obstructive pulmonary disease (COPD). RECENT FINDINGS: Altered body composition and skeletal muscle dysfunction in COPD suggest that exercise capacity can be targeted via several metabolic routes. Muscle metabolic alterations in COPD include a reduced oxidative metabolism and enhanced susceptibility for oxidative stress...

Oxidative stress, manifested by protein oxidation, lipid peroxidation, DNA oxidation and 3-nitrotyrosine formation, among other indices, is observed in Alzheimer's disease (AD) brain. Amyloid beta-peptide (1-42) [Abeta(1-42)] may be central to the pathogenesis of AD. Our laboratory and others have implicated Abeta(1-42)-induced free radical oxidative stress in the neurodegeneration observed in AD brain. This paper reviews some of these studies from our laboratory. Recently, we showed both in-vitro and in-vivo that methionine residue 35 (Met-35) of Abeta(1-42) was critical to its oxidative stress and neurotoxic properties...

The mnd mouse, a model of neuronal ceroid lipofusinosis (NCL), has a profound vitamin E deficiency in sera and brain, associated with cerebral deterioration characteristic of NCL. In this study, the vitamin E deficiency is corrected using dietary supplementation. However, the histopathological features associated with NCL remained. With use of a bioinformatics approach based on high-resolution solid and solution state 1H-NMR spectroscopy and principal component analysis (PCA), the deficits associated with NCL are defined in terms of a metabolic phenotype...

The free radical theory of aging proposes that reactive oxygen species (ROS) cause oxidative damage over the lifetime of the subject. It is the cumulative and potentially increasing amount of accumulated damage that accounts for the dysfunctions and pathologies seen in normal aging. We have previously demonstrated that both normal rodent brain aging and normal human brain aging are associated with an increase in oxidative modification of proteins and in changes in plasma membrane lipids. Several lines of investigation indicate that one of the likely sources of ROS is the mitochondria...

Rats were given a 200 mg/kg body weight daily dose of alpha-tocopherol by i.p. injection for 15 days. This resulted in elevated levels of glutathione in both liver and brain, and in a reduced hepatic rate of generation of reactive oxygen species. The depression of hepatic and cerebral glutathione levels in ethanol-consuming rats was prevented by simultaneous treatment with alpha-tocopherol. Other putative indices of hepatic pro-oxidant events, namely levels of mixed function oxidase and proteolytic activity, were elevated by alpha-tocopherol both in the presence and absence of ethanol...

1H NMR was used to analyze human cerebrospinal fluid (CSF) from a group of neurological disease controls and from a vitamin B12 deficient patient. The spectra were acquired at either 7.06 or 9.40 T at ambient temperature with CSF freeze dried and reconstituted in 2H2O. 3-Trimethylsilyl propionate was used as an internal chemical shift and concentration reference. All of the CSF samples showed peaks for lactate, L-alanine, acetate, glutamine, citrate, creatine/creatinine and sugar resonances. There was good agreement between the metabolite concentrations as determined by NMR with those obtained using conventional chemical methods...
