Abstract
Selenoprotein P is a hepatokine with antioxidative properties that eliminate a physiologic burst of reactive oxygen species required for intracellular signal transduction. Serum levels of selenoprotein P are elevated during aging and in people with type 2 diabetes, non-alcoholic fatty liver disease, and hepatitis C. However, how serum levels of full-length selenoprotein P are regulated largely remains unknown, especially in the general population. To understand the significance of serum selenoprotein P levels in the general population, we evaluated intrinsic and environmental factors associated with serum levels of full-length selenoprotein P in 1,183 subjects participating in the Shika-health checkup cohort. Serum levels of selenium were positively correlated with liver enzymes and alcohol intake and negatively correlated with body mass index. Serum levels of selenoprotein P were positively correlated with age, liver enzymes, and alcohol intake. In multiple regression analyses, alcohol intake was positively correlated with serum levels of both selenium and selenoprotein P independently of age, gender, liver enzymes, and fatty liver on ultrasonography. In conclusion, alcohol intake is associated with elevated serum levels of selenium and selenoprotein P independently of liver enzyme levels and liver fat in the general population. Moderate alcohol intake may exert beneficial or harmful effects on health, at least partly by upregulating selenoprotein P. These findings increase our understanding of alcohol-mediated redox regulation and form the basis for the adoption of appropriate drinking guidelines.

Abstract
PURPOSE To assess whether alcohol consumption is associated with the long-term incidence of cataract or cataract surgery. DESIGN Population-based prospective cohort study. METHODS A total of 3654 persons aged 49+ years were examined at baseline and 2564 were re-examined after 5 and/or 10 years. Lens photographs were taken at each visit and assessed using the Wisconsin Cataract Grading System by masked graders. An interviewer-administered questionnaire was used to collect information on alcohol consumption. RESULTS No significant associations were observed between alcohol consumption and long-term risk of nuclear, cortical, and posterior subcapsular cataract. However, after adjusting for age, gender, smoking, diabetes, myopia, socioeconomic status, and steroid use, total alcohol consumption of over 2 standard drinks per day was associated with a significantly increased likelihood of cataract surgery, when compared to total daily alcohol consumption of 1 to 2 standard drinks (adjusted odds ratio [OR] 2.10, 95% confidence interval [CI] 1.16-3.81). Abstinence from alcohol was also associated with increased likelihood of cataract surgery when compared to a total alcohol consumption of 1 to 2 standard drinks per day (adjusted OR 2.36, 95% CI 1.25-4.46). CONCLUSION A U-shaped association of alcohol consumption with the long-term risk of cataract surgery was found in this older cohort: moderate consumption was associated with 50% lower cataract surgery incidence, compared either to abstinence or heavy alcohol consumption.

Abstract
OBJECTIVES To correlate the oxidative state of postabsorptive blood plasma after consumption of one or three drinks of different beverages with known J-shaped epidemiological risk curves. DESIGN, INTERVENTIONS, AND MAIN OUTCOME MEASURES Red wine, lager beer, stout (alcoholic and alcohol-free), with antioxidant activity, and an aqueous solution of alcohol were compared for the plasma antioxidant or pro-oxidant activity in human volunteers following consumption of one or three typical drinks containing equivalent amounts of alcohol (except for an alcohol-free stout used as a control for stout). RESULTS One drink of red wine, lager beer, or stout (5% alcohol v/v, and alcohol-free) significantly increased the average antioxidant activity in plasma samples obtained from volunteers averaged over 240 min. Three drinks of red wine, lager beer, or stout (5% alcohol v/v, and alcohol-free) significantly increased the average pro-oxidant activity in plasma samples obtained from volunteers averaged over 360 min. For a solution of alcohol, three drinks resulted in pro-oxidant plasma on average, whereas while one drink did not significantly affect the plasma oxidative status. A preliminary experiment in which two volunteers showed a significantly increased time to metabolize ethanol after ingestion resulted in elevated antioxidant activity in plasma for lager beer and red wine. CONCLUSIONS One drink of red wine, beer, or stout provided equivalent increases in plasma antioxidant activity. Three drinks of red wine, beer, or stout provided equivalent increases in plasma pro-oxidant activity. This may explain, at least in part, the decreased risk of cataract and atherosclerosis from daily consumption of one drink of different types of alcoholic beverages as well as the increased risk from daily consumption of three drinks of alcoholic beverages. The plasma pro-oxidant activity appears to be due to ethanol metabolism, whereas the antioxidant activity may be due to the absorption of polyphenols in the beverages.

Abstract
The free phenols have been measured in 15 lagers, 6 porters and ales, and 11 light and nonalcoholic beers. Phenols were measured colorimetrically using an oxidation-reduction reaction with Folin-Ciocalteu reagent and catechin as the standard. The order of phenol concentration was ales > lagers > low calorie > nonalcoholic. The quality of antioxidants of the major phenols in beers and the quality of beer antioxidants were measured by (1) dose-response inhibition of lower density lipoprotein oxidation and (2) concentration of phenols in the beers at which 50% of the peroxide was destroyed in a luminescent assay for antioxidant activity. The beers' lipoprotein antioxidant quality was clearly superior to that of vitamin antioxidants and to that of the phenol ingredients, suggesting synergism among the antioxidants in the mixture. The average per capita consumption of beer in the United States in 2000 was 225 mL/day, equivalent to 42 mg/day of catechin equivalents. Beer provides more antioxidants per day than wine in the U.S. diet. A dark beer and a lager beer were given at two concentrations to cholesterol-fed hamsters, an animal model of atherosclerosis. At the high dose ((1)/(2)-diluted beer) both lager and dark beer significantly inhibited atherosclerosis compared to a control of 2% alcohol. At the high dose, lager significantly decreased cholesterol and triglycerides, and both beers acted as in vivo antioxidants by decreasing the oxidizability of lower density lipoproteins. At the low dose ((1)/(10)-diluted beer) only the lager beer significantly decreased atherosclerosis compared to the 0.4% alcohol control. The polyphenols in the beers appear to be responsible for the benefits of beer in this model. Lager beer inhibited atherosclerosis at a human equivalent dose in this hamster model of atherosclerosis.

Abstract
Diabetic patients have elevated levels of glucose in their blood and other body fluids. This project studied the effect of high-glucose concentrations (HG) on the protein oxidation in cultured lens cells and in crystalline protein solution. In addition, we also examined the effect of HG on the oxidation and turbidity (aggregation) of albumin protein solution. This study also examined whether vitamin B6 [pyridoxine (P), pyridoxamine (PM)] or n-acetylcysteine (NAC) is capable of preventing protein oxidation similar to that seen in cataracts. For cell culture studies, rabbit lens cells were cultured in control or HG medium at 37 degrees C for 2 d. For studies with protein solution, a buffered solution of serum albumin or crystalline protein was incubated with normal glucose (5 mM) or HG (50-100 mM) in a water bath at 37 degrees C for 4 d. All treatments were carried out with and without the addition of P, PM, or NAC. We found significantly higher levels of carbonyl protein (an index of protein oxidation) in HG-treated compared with normal glucose-treated lens cells and in crystalline protein solution. P, PM, and NAC significantly decreased the protein oxidation in lens cells and crystalline protein solution. We also found significantly higher levels of protein oxidation and turbidity (an index of protein aggregation) and its inhibition by P, PM, and NAC in HG-treated compared with normal glucose-treated albumin solution. This suggests that HG can cause the oxidation and modification of proteins in the lens, and that vitamin B6 and NAC supplementation may be helpful in slowing the oxidation of lens proteins. This study explains the cause of early cataract development and the potential benefit of supplementation with vitamin B6 and NAC in the prevention of the development of cataract among the diabetic population.

Abstract
OBJECTIVE A J-shaped association has been demonstrated between alcohol consumption and atherosclerosis. Insulin resistance, also a risk factor for atherosclerosis, has been shown to have a similar J-shaped association with alcohol intake. This raises the question of whether insulin sensitivity (S(I)) is a causal intermediate in the alcohol-atherosclerosis relationship. RESEARCH DESIGN AND METHODS The Insulin Resistance Atherosclerosis Study was a multicenter cohort study designed to investigate relationships among S(I), risk factors for cardiovascular disease, and carotid artery atherosclerosis. Using regression analysis, we tested whether adjustment for S(I) attenuated the alcohol-atherosclerosis relationship observed at baseline. RESULTS A J-shaped association was observed between alcohol consumption and common carotid artery intimal medial thickness. The protective aspect of the alcohol-atherosclerosis relationship was attenuated by 25% after the adjustment for S(I). However, an interaction was observed between alcohol consumption and glucose tolerance (GT) status. In comparison with never drinkers, all levels of alcohol consumption were associated with less atherosclerosis in participants with normal GT status. Participants with impaired GT status (but not diabetes) demonstrated a J-shaped alcohol-atherosclerosis association. All levels of alcohol consumption were associated with more atherosclerosis in participants with diabetes. CONCLUSIONS S(I) may be a causal intermediate at protective levels of alcohol intake, but an alcohol-GT interaction precluded a definitive conclusion. Moderate alcohol consumption may increase the risk of atherosclerosis in people with diabetes. These findings contrast with previous reports and do not support current recommendations regarding moderate alcohol consumption in people with diabetes. More research is needed to clarify this issue.

Abstract
The French have low coronary heart disease mortality with high fat consumption; this epidemiological anomaly is known as the "French Paradox" and is commonly attributed to the consumption of red wine. However, epidemiology studies have not convincingly shown a superiority of red wine vs. alcohol or other alcoholic beverages. We have used the hamster model of atherosclerosis to determine the active ingredient(s) of red wine responsible for the beneficial effect. Hamsters (nine in each group) were given a cholesterol/saturated fat for 10 weeks to induce foam cell formation. Water or 6.75% ethanol was given to the control groups. Beverages tested included red wine, dealcoholized red wine, and red grape juice, all diluted in half. Ethanol and all beverages caused a significant reduction in atherosclerosis. The combination of ethanol in red wine had the largest effect in decreasing atherosclerosis by both hypolipemic and antioxidant mechanisms. When compared with dealcoholized wine and normalized to polyphenol dose, red wine's beneficial effects can be attributed entirely to the polyphenols. Grape juice had a significant benefit at a much lower dose of polyphenols than the wines. Grape juice was calculated to be much more effective than red wine or dealcoholized red wine at the same polyphenol dose in inhibiting atherosclerosis and improving lipids and antioxidant parameters. This data suggests that polyphenolic beverages from grapes are beneficial in inhibiting atherosclerosis by several mechanisms. Grape juice or non-alcoholic red wine are an excellent alternative to red wine in this model of atherosclerosis.

Abstract
This study was designed to evaluate the effect of ethanol on the peroxidation of human low-density lipoprotein (LDL) initiated by oxygen free radicals (O(2)(.-) and (.)OH in the absence of ethanol; O(2)(.-) and ethanol-derived peroxyl radicals, RO(2)(.), in the presence of ethanol) generated by gamma radiolysis. Initial radiolytic yields as determined by several markers of lipid peroxidation [i.e. decrease in endogenous antioxidants alpha-tocopherol and beta-carotene, formation of conjugated dienes and of thiobarbituric acid-reactive substances (TBARS)] were determined in 3 g liter(-1) LDLs (expressed as total LDL concentration) in the absence of ethanol or its presence at six different concentrations (0.42-17 x 10(-2) mol liter(-1)). Ethanol acted as an antioxidant by decreasing the rate of consumption of LDL endogenous antioxidants and the yields of formation of lipid peroxidation products, and by delaying the onset of the propagation phase for conjugated dienes and TBARS. With regard to the different markers studied, except for alpha-tocopherol and beta-carotene consumption, the effect of ethanol did not appear to be dependent on its concentration. Indeed, (.)OH were scavenged by ethanol at the lowest ethanol concentration (0.42 x 10(-2) mol liter(-1)), leading to RO(2)(.). These RO(2)(.) resulted in lower radiation-induced yields related to endogenous antioxidant consumption or to formation of lipid peroxidation products (for example, approximately 10% of RO(2)(.) oxidized LDLs from TBARS). Thus, under our in vitro conditions, ethanol behaved as an antioxidant when added to the LDL solutions. This should be taken into account in the reported antioxidant activity of wine. This is also of interest when lipophilic compounds have to be added as ethanolic solutions to LDLs to evaluate in vitro their antioxidant activity toward LDL peroxidation.

Abstract
BACKGROUND Moderate consumption of alcoholic drinks seems to reduce the risks of developing cardiovascular disease, stroke, and cataracts, perhaps through antioxidant actions of their alcohol, flavonoid, or polyphenol contents. "Shaken, not stirred" routinely identifies the way the famous secret agent James Bond requires his martinis. OBJECTIVES As Mr Bond is not afflicted by cataracts or cardiovascular disease, an investigation was conducted to determine whether the mode of preparing martinis has an influence on their antioxidant capacity. DESIGN Stirred and shaken martinis were assayed for their ability to quench luminescence by a luminescent procedure in which hydrogen peroxide reacts with luminol bound to albumin. Student's t test was used for statistical analysis. RESULTS Shaken martinis were more effective in deactivating hydrogen peroxide than the stirred variety, and both were more effective than gin or vermouth alone (0.072% of peroxide control for shaken martini, 0.157% for stirred v 58.3% for gin and 1.90% for vermouth). The reason for this is not clear, but it may well not involve the facile oxidation of reactive martini components: control martinis through which either oxygen or nitrogen was bubbled did not differ in their ability to deactivate hydrogen peroxide (0.061% v 0. 057%) and did not differ from the shaken martini. Moreover, preliminary experiments indicate that martinis are less well endowed with polyphenols than Sauvignon white wine or Scotch whisky (0.056 mmol/l (catechin equivalents) shaken, 0.060 mmol/l stirred v 0.592 mmol/l wine, 0.575 mmol/l whisky). CONCLUSIONS 007's profound state of health may be due, at least in part, to compliant bartenders.
