One of the biochemical pathways affected by aging in all organisms is protein synthesis. Previous reports from our laboratory have indicated that the elongation step is specially affected by aging as a consequence of alterations in elongation factor-2 (eEF-2). In the present work, we studied in vitro the effectiveness of several individual nutritional antioxidants in protecting the levels of hepatic eEF-2 subjected to oxidative stress induced by cumene hydroperoxide. The in vitro system… 
Lipid Peroxidation: Production, Metabolism, and Signaling Mechanisms of Malondialdehyde and 4-Hydroxy-2-Nonenal
TLDR
This review focuses on biochemical concepts of lipidPeroxidation, production, metabolism, and signaling mechanisms of two main omega-6 fatty acids lipid peroxidation products: malondialdehyde (MDA) and, in particular, 4-hydroxy-2-nonenal (4-HNE), summarizing not only its physiological and protective function as signaling molecule stimulating gene expression and cell survival, but also its cytotoxic role inhibiting geneexpression and promoting cell death.
Alfa lipoik asidin rat karaciğer homojenatlarinda hidrojen peroksit ile indüklenmiş lipid peroksidasyonuna etkisi (The effect of alpha lipoic acid on hydrogen peroxide-induced lipid peroxidation in rat liver homogenates)
TLDR
The findings suggest that lipid peroxidation is induced in the experimental setups where hydrogen peroxide are applied, and the reason of significantly lower malondialdehyde and higher glutathione levels in alpha lipoic acid group than activation groups may be a result of the antioxidant property of alpha lipOic acid.
Effect of α-lipoic acid and exercise training on cardiovascular disease risk in obesity with impaired glucose tolerance
TLDR
It is reported that α-lipoic acid ingestion may increase the atherogenicity of LDL when ingested in isolation of exercise, suggesting that in IGT the use of this antioxidant treatment does not ameliorate metabolic disturbances, but instead may detrimentally contribute to the pathogenesis of atherosclerosis and development of CVD.
Effects of brain-directed nutrients on cerebral blood flow and neuropsychological testing: a randomized, double-blind, placebo-controlled, crossover trial.
TLDR
A region of interest (ROI) analysis for each of the 2-mo phases showed significant improvement in rCBF for the BDNs as compared to the placebo as well as an assessment of the differences in cognitive and emotional function.
Reversing Brain Damage in Former NFL Players: Implications for Traumatic Brain Injury and Substance Abuse Rehabilitation
TLDR
It is demonstrated that cognitive and cerebral blood flow improvements are possible in this group with multiple interventions, and statistically significant increases in scores of attention, memory, reasoning, information processing speed and accuracy are demonstrated.

Effect of Oxidative Stress, Produced by Cumene Hydroperoxide, on the Various Steps of Protein Synthesis
TLDR
The measurement of both carbonyl groups content and ADP-ribosylatable elongation factor 2 (EF-2), the main protein involved in the elongation step, indicates that under CH treatment EF-2 is oxidatively modified and a lower amount of active EF-1 is present.
Antioxidant defence mechanisms: from the beginning to the end (of the beginning).
TLDR
An important area of future research will be elucidation of the reasons why levels of steady-state oxidative damage to DNA and lipids vary so much between individuals, and their predictive value for the later development of human disease.
