Abstract
Rodgersia podophylla A. Gray (R. podophylla) is a traditional Chinese medicine with various pharmacological effects. However, its antioxidant and anti-hyperuricemia components and mechanisms of action have not been explored yet. In this study, we first assessed the antioxidant potential of R. podophylla with 2,2-diphenyl-1-picrylhydrazyl (DPPH), 2,2'-azino-bis(3-ethylbenzothiazoline-6-sulfonic acid) (ABTS) and ferric ion reducing antioxidant power (FRAP) assays. The results suggested that the ethyl acetate (EA) fraction of R. podophylla not only exhibited the strongest DPPH, ABTS radical scavenging and ferric-reducing activities, but also possessed the highest total phenolic and total flavonoid contents among the five fractions. After that, the potential superoxide dismutase (SOD) and xanthine oxidase (XOD) ligands from the EA fraction were quickly screened and identified through the bio-affinity ultrafiltration liquid chromatography-mass spectrometry (UF-LC-MS). Accordingly, norbergenin, catechin, procyanidin B2, 4-O-galloylbergenin, 11-O-galloylbergenin, and gallic acid were considered to be potential SOD ligands, while gallic acid, 11-O-galloylbergenin, catechin, bergenin, and procyanidin B2 were recognized as potential XOD ligands, respectively. Moreover, these six ligands effectively interacted with SOD in molecular docking simulation, with binding energies (BEs) ranging from -6.85 to -4.67 kcal/mol, and the inhibition constants (Ki) from 9.51 to 379.44 μM, which were better than the positive controls. Particularly, catechin exhibited a robust binding affinity towards XOD, with a BE value of -8.54 kcal/mol and Ki value of 0.55 μM, which surpassed the positive controls. In conclusion, our study revealed that R. podophylla possessed remarkable antioxidant and anti-hyperuricemia activities and that the UF-LC-MS method is suitable for screening potential ligands for SOD and XOD from medicinal plants.

Abstract
The aim of this study was to gain more complete information about the relationships between some endogenous antioxidants and the malondialdehyde (MDA) as a marker of lipid peroxidation, during D-galactose induced senescence. The activities of superoxide dismutase (SOD), glutathione peroxidase (GPx), catalase (CAT) and the concentrations of uric acid (UA) in plasma and MDA in erythrocyte’s hemolysate, were determined in 15 D-galactose (D-gal), treated rats and compared with 15 placebo. The activity of the erythrocyte’s CAT was found significantly increased due to the senescence. The ratio of the activities of antioxidant enzymes R=SOD/(GPx+CAT) was significantly decreased due to the senescence and negatively correlated with the MDA (ρ=–0.524, p=0.045). The antioxidant enzymes SOD and GPx negatively correlated with the MDA, while CAT displayed no correlation. Further, the UA positively correlated with the ratio of activities of the antioxidant enzymes R=SOD/(GPx+CAT), (ρ=0.564, p=0.029 for senescent rats). Obtained results may contribute to better understanding of the process of D-gal induced senescence in the erythrocytes.

Abstract
The objective of the present study was to investigate the effects of grape seed extract (GSE) supplementation on oxidative stress and antioxidant defense markers in liver tissue of acutely and chronically exercised rats. Rats were randomly assigned to six groups: Control (C), Control Chronic Exercise (CE), Control Acute Exercise (AE), GSE-supplemented Control (GC), GSE-supplemented Chronic Exercise(GCE) and GSE-supplemented Acute Exercise (GAE). Rats in the chronic exercise groups were subjected to a six-week treadmill running and in the acute exercise groups performed an exhaustive running. Rats in the GSE supplemented groups received GSE (100 mg.kg(-1) .day(-1) ) in drinking water for 6 weeks. Liver tissues of the rats were taken for the analysis of malondialdehyde (MDA), nitric oxide (NO) levels and total antioxidant activity (AOA) and xanthine oxidase (XO) activities. MDA levels decreased with GSE supplementation in control groups but increased in acute and chronic exercise groups compared to their non-supplemented control. NO levels increased with GSE supplementation. XO activities were higher in AE group compared to the CE group. AOA decreased with GSE supplementation. In conclusion, while acute exercise triggers oxidative stress, chronic exercise has protective role against oxidative stress. GSE has a limited antioxidant effect on exercise-induced oxidative stress in liver tissue.

Abstract
It is well known that lipid peroxidation increases with age, and alcohol drinking further exacerbates this damage. The present study determined the effect of regular exercise training on alcohol-induced oxidative damage and antioxidant status in the liver of aged animals. The age-matched Wistar albino rats (3 months young, n=24; 18 months old, n=24) were evenly divided into four groups: control (C), exercise trained (Ex), ethanol drinking (Et), and exercise plus ethanol drinking (Ex+Et). With ethanol drinking, hepatic malondialdehyde (MDA) level was significantly elevated above control (P<.001), whereas glutathione (GSH) and ascorbic acid (vitamin C) contents were significantly decreased below control. These changes were found to be greater in the aged rats than those of the young rats. For both age groups, exercise training significantly reversed the increase in MDA and decreases in GSH and ascorbic acid induced by ethanol drinking. The present study showed that ethanol-induced deterioration in lipid peroxidation and reduction in antioxidant status in the liver were exacerbated with age. Here, we found that exercise training significantly reversed the adverse conditions that were caused by ethanol in aged rats.

Abstract
Accumulating evidence strongly suggests that oxidative stress underlies aging processes. Research provides consistent evidence that calorie restriction (CR) reduces age-related oxidative stress and has anti-inflammatory properties. However, information is lacking on the molecular mechanism that would better define the interrelation of reactive oxygen species and nitrogen species and the pro-inflammatory states of the aging process. In this review, the biochemical and molecular bases of the inflammatory process in the aging process are analyzed to delineate the molecular inflammation hypothesis of aging. The key players involved in the proposed hypothesis are the age-related upregulation of NF-kappa B, IL-1 beta, IL-6, TNFalpha, cyclooxygenase-2, and inducible NO synthase, all of which are attenuated by CR. Furthermore, age-related NF kappa B activation is associated with phosphorylation by I kappa B kinase/NIK and MAPKs, while CR blocked these activation processes. The modulation of these factors provides molecular insights of the anti-inflammatory action of CR in relation to the aging process. Based on available finding and our recent supporting evidence, we prefer to use "molecular inflammation" to emphasize the importance of the molecular reaction mechanisms and their aberrance, predisposing to fully expressed chronic inflammatory phenomena. It was further proposed that CR's major force of the regulation of redox-sensitive inflammation may well be its life-prolonging action.

Abstract
Four female and four male crew members, including two of the present authors (R. Walford and T. MacCallum)--seven of the crew being ages 27 to 42 years, and one aged 67 years--were sealed inside Biosphere 2 for two years. During seven eighths of that period they consumed a low-calorie (1750-2100 kcal/d) nutrient-dense diet of vegetables, fruits, nuts, grains, and legumes, with small amounts of dairy, eggs, and meat (approximately 12% calories from protein, approximately 11% from fat, and approximately 77% from complex carbohydrates). They experienced a marked and sustained weight loss of 17 +/- 5%, mostly in the first 8 months. Blood was drawn before entry into Biosphere 2, at many time-points inside it, and four times during the 30 months following exit from it and return to an ad libitum diet. Longitudinal studies of 50 variables on each crew member compared outside and inside values by means of a Bayesian statistical analysis. The data show that physiologic (e.g., body mass index, with a decrease of 19% for men and 13% for women; blood pressure, with a systolic decrease of 25% and a diastolic decrease of 22%), hematologic (e.g., white blood cell count, decreased 31%), hormonal (e.g., insulin, decreased 42%; T3, decreased 19%), biochemical (e.g., blood sugar, decreased 21%; cholesterol, decreased 30%), and a number of additional changes, including values for rT3, cortisol, glycated hemoglobin, plus others, resembled those of rodents or monkeys maintained on a calorie-restricted regime. Significant variations in several substances not hitherto studied in calorie-restricted animals are also reported (e.g., androstenedione, thyroid binding globulin, renin, and transferrin). We conclude that healthy nonobese humans on a low-calorie, nutrient-dense diet show physiologic, hematologic, hormonal, and biochemical changes resembling those of rodents and monkeys on such diets. With regard to the health of humans on such a diet, we observed that despite the selective restriction in calories and marked weight loss, all crew members remained in excellent health and sustained a high level of physical and mental activity throughout the entire 2 years.
