Abstract
Polyphenols are secondary plant metabolites synthesized during the development of the grape berry as a response to stress conditions. They are important constituents in red wines that contribute to the sensory properties and antioxidant activity of wines. Due to the development of highly sophisticated analytical devices, it is now possible to characterize the structure of highly polymerized polyphenols and obtain a full polyphenol profile of red wines. Red wine polyphenols include the ones present in grapes as well as new polyphenol products formed during the winemaking process. Among them, the most important groups and their representatives are flavanols (catechin), stilbenes (trans-resveratrol), flavonols (quercetin) and hydroxybenzoic acids (gallic acid). It is known that polyphenols exhibit beneficial effects on human health, such as anti-inflammatory, anticarcinogenic and cardio-protective effects. Many studies have been conducted on the health effects of red wine polyphenols in cancer chemopreventive activities, neuroprotective effects and impact on cardiovascular diseases, gut microbiota in humans, etc. This review will provide major scientific findings on the impact of red wine polyphenols on human health as well as a review of polyphenols present in red wines and their main features.

Abstract
Dietary habits are a determining factor of the higher incidence and prevalence of chronic non-communicable diseases (NCDs). In the aim to find a possible preventive and intervention strategy, the Mediterranean diet (MedDiet) has been proposed as an effective approach. Within the MedDiet, moderate wine consumption with meals is a positive item in the MedDiet score; however, recent studies have reported a dose-response association between alcohol consumption and higher risk of a large number of NCDs. This review aimed to evaluate the association between NCDs and wine consumption in the framework of the MedDiet, with a simple review of 22 studies of the highest-level literature published over the last five years. We found that the information regarding the effects of wine in different health outcomes has not varied widely over the past five years, finding inconclusive results among the studies evaluated. Most of the literature agrees that light to moderate wine intake seems to have beneficial effects to some extent in NCDs, such as hypertension, cancer, dyslipidemia and dementia, but no definitive recommendations can be made on a specific dose intake that can benefit most diseases.

Dich N, Doan SN. Moderate emotional reactions to stressful life events are associated with lowest risk of increased alcohol consumption: evidence from the Whitehall II study.

Abstract
BACKGROUND Research investigating the associations between stress-related negative emotions and alcohol consumption often assumes a linear dose-response relationship. Based on the current theories of emotions, we questioned this assumption and hypothesized that both very low and very high levels of negative emotional response (NER) to stressful life events are related to increased alcohol consumption. METHODS We used data from Phases 1 (1985-88) and 2 (1989-90) of the British Whitehall II study. At both phases, participants reported on their alcohol consumption, recent stressful events and the NER to the events. Two thousand and sixteen participants without recent stressful events at baseline were selected. Logistic regression was used to model the association between emotional response at baseline and increased frequency of alcohol consumption between the two phases. RESULTS The likelihood of increased alcohol consumption increased with the number of recent stressful events. Among participants with at least one event, 17% increased alcohol consumption, compared with 14% of those who reported no events. Participants with average NER were at lowest risk (14%) of increasing alcohol consumption after major life events. Those with highest NER were significantly more likely to increase alcohol consumption (20%) than those with average NER, but the difference between those with highest NER and those with lowest NER (17%) was not statistically significant. CONCLUSIONS Increases in alcohol consumption following stressful events are least likely if people experience moderate levels of NER to events. Negative emotions in moderate doses should not be regarded as a risk factor for unhealthy behaviours, but rather a potentially protective factor.

Abstract
Polyphenols, including anthocyanins, flavonoids and stilbenes, which constitute one of the most abundant and ubiquitous groups of plant metabolites, are an integral part of the human diet. Resveratrol (3,5,4'-trihydroxystilbene), a naturally occurring polyphenol produced by some plants as a self-defence agent, has an antifungal activity. Resveratrol has been found in some plants (such as grapevine, pine and peanuts) and is considered to have beneficial effects also on human health. The number of studies on resveratrol greatly increased in PubMed database since 1997, after the anticancer effect of this molecule was first reported. The interest in resveratrol in grape was originally sparked by epidemiological studies indicating an inverse relationship between long-standing moderate consumption of red wine and the risk of coronary heart disease; this effect has been ascribed to resveratrol, which possesses diverse biochemical and physiological properties, including antiplatelet and anti-inflammatory proprieties, and provides a wide range of health benefits ranging from chemoprevention to cardioprotection. Recently, resveratrol has been described as an anti-aging compound. The consumption of resveratrol (red wine) together with a Mediterranean diet or a fast-food meal (“McDonald'sMeal”) had a positive impact on oxidized (ox-) LDL and on the expression of oxidative and inflammatory genes. Therefore, this review summarized the most important scientific data about healing and preventive potential of resveratrol, acting as cardioprotective, neuroprotective, chemopreventive and antioxidant agent.

Abstract
Preclinical studies have suggested that polyphenols extracted from red wine (RWPs) favourably affect insulin sensitivity, but there is controversy over whether RWPs exert similar effects in humans. The aim of the present study was to determine whether RWPs improve insulin sensitivity in obese volunteers. Obese (body mass index >30 kg/m2 ) volunteers were randomly allocated to RWPs 600 mg/d (n = 14) or matched placebo (n = 15) in a double-blind parallel-arm study for 8 weeks. The participants were investigated at baseline and at the end of the study. Insulin sensitivity was determined using a hyperinsulinaemic-euglycaemic clamp (M-value), a mixed-meal test (Matsuda index), and homeostatic model assessment of insulin resistance (HOMA-IR). RWPs elicited no significant changes in M-value (RWP group: median [interquartile range; IQR] baseline 3.0 [2.4; 3.6]; end of study 3.3 [2.4; 4.8] vs placebo group: median [IQR] baseline 3.4 [2.8; 4.4]; end of study 2.9 [2.8; 5.9] mg/kg/min; P = .65), in Matsuda index (RWP group: median [IQR] baseline 3.3 [2.2; 4.8]; end of study 3.6 [2.4; 4.8] vs placebo group: median [IQR] baseline 4.0 [3.0; 6.0]; end of study 4.0 [3.0; 5.2]; P = .88), or in HOMA-IR. This study showed that 8 weeks of RWP supplementation did not improve insulin sensitivity in 29 obese volunteers. Our findings were not consistent with the hypothesis that RWPs ameliorate insulin resistance in human obesity.

Resveratrol Cardioprotection Against Myocardial Ischemia/Reperfusion Injury Involves Upregulation of Adiponectin Levels and Multimerization in Type 2 Diabetic Mice.

Abstract
Downregulation of adiponectin (APN) multimerization is significantly correlated with the aggravation of myocardial ischemia/reperfusion (MI/R) injury in type 2 diabetes mellitus (T2DM). Resveratrol (RSV) upregulates APN multimerization in adipocytes, but whether RSV improves endogenous APN multimerization and thus attenuates MI/R injury in T2DM mice has never been investigated. T2DM mice were treated with 10 mg/kg RSV daily for 3 weeks, followed by 30 minutes of myocardial ischemia and 3 hours or 24 hours of reperfusion. RSV administration alleviated MI/R injury in diabetic mice, as evidenced by reduced infarct size, cardiomyocyte apoptosis, and caspase-3 activity, and improved cardiac function. Moreover, RSV reversed the downregulated APN levels and multimerization both in plasma and adipose tissue, accompanied by increased disulfide bond A oxidoreductase-like protein (DsbA-L) expression in T2DM mice. Conversely, serving as a key downstream molecule of APN in ameliorating MI/R injury, inhibition of AMP-activated protein kinase (AMPK) significantly attenuated the cardioprotective effects of RSV. In conclusion, long-term administration of RSV upregulates adiponectin levels and multimerization in T2DM mice, consequently attenuating MI/R injury partially through APN-AMPK signaling.

Polyphenols from Wine Lees as a Novel Functional Bioactive Compound in the Protection Against Oxidative Stress and Hyperlipidaemia. Food Technol Biotechnol 2017; 55:109-116. [PMID: 28559739 PMCID: PMC5434373 DOI: 10.17113/ftb.55.01.17.4894] [Citation(s) in RCA: 15] [Impact Index Per Article: 2.1] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/14/2016] [Accepted: 10/13/2016] [Indexed: 11/12/2022] Open
Abstract
The study examines the potential of wine industry by-product, the lees, as a rich mixture of natural polyphenols, and its physiological potential to reduce postprandial metabolic and oxidative stress caused by a cholesterol-rich diet in in vivo model. Chemical analysis of wine lees showed that their total solid content was 94.2%. Wine lees contained total phenols, total nonflavonoids and total flavonoids expressed in mg of gallic acid equivalents per 100 g of dry mass: 2316.6±37.9, 1332.5±51.1 and 984.1±28.2, respectively. The content of total anthocyanins expressed in mg of cyanidin-3-glucoside equivalents per 100 g of dry mass was 383.1±21.6. Antioxidant capacity of wine lees determined by the DPPH and FRAP methods and expressed in mM of Trolox equivalents per 100 g was 259.8±1.8 and 45.7±1.05, respectively. The experiment lasted 60 days using C57BL/6 mice divided in four groups: group 1 was fed normal diet and used as control, group 2 was fed normal diet with added wine lees, group 3 was fed high-cholesterol diet (HCD), i.e. normal diet with the addition of sunflower oil, and group 4 was fed HCD with wine lees. HCD increased serum total cholesterol (TC) by 2.3-fold, triacylglycerol (TAG) by 1.5-fold, low-density lipoprotein (LDL) by 3.5-fold and liver malondialdehyde (MDA) by 50%, and reduced liver superoxide dismutase (SOD) by 50%, catalase (CAT) by 30% and glutathione (GSH) by 17.5% compared to control. Conversely, treatment with HCD and wine lees reduced TC and LDL up to 1.4 times more than with HCD only, with depletion of lipid peroxidation (MDA) and restoration of SOD and CAT activities in liver, approximating values of the control. HDL levels were unaffected in any group. Serum transaminase activity showed no hepatotoxic properties in the treatment with lees alone. In the proposed model, wine lees as a rich polyphenol source could be a basis for functional food products without alcohol.

Do grape polyphenols improve metabolic syndrome components? A systematic review. Eur J Clin Nutr 2017; 71:1381-1392.

Abstract
BACKGROUND/OBJECTIVES Epidemiological, in vitro and animal studies suggest that grape polyphenols, such as those present in wine, have favorable effects on the metabolic syndrome. However, controversy remains whether treatment with grape polyphenols is effective in humans. Here, we aimed to systemically review the effects of grape polyphenols on metabolic syndrome components in humans. SUBJECTS/METHODS We systematically searched Medline, EMBASE and the Cochrane database for all clinical trials assessing the effects of grape polyphenols on insulin sensitivity, glycemia, blood pressure or lipid levels. We screened all titles and reviewed abstracts of potentially relevant studies. Full papers were assessed for eligibility and quality-rated according to the Jadad scale by two independent assessors. RESULTS Thirty-nine studies met the eligibility criteria. In individuals without component criteria of the metabolic syndrome, only low- and medium-quality studies were found with primarily neutral results. In individuals with the metabolic syndrome or related conditions, one of two high-quality studies suggested improvement in insulin sensitivity. Glycemia was improved in 2 of 11 lower-quality studies and 2 of 4 high-quality studies. Seven of 22 studies demonstrated a significant decrease in blood pressure, but only one was of high quality. Two of four high-quality studies pointed towards effects on total cholesterol while other lipidemic parameters were not affected. CONCLUSIONS No compelling data exist that grape polyphenols can positively influence glycemia, blood pressure or lipid levels in individuals with or without the metabolic syndrome. Limited evidence suggests that grape polyphenols may improve insulin sensitivity.

Abstract
The aim of this paper is to analyze the a priori dietary indexes used in the studies that have evaluated the role of the Mediterranean Diet in influencing the risk of developing cardiovascular disease. All the studies show that this dietary pattern protects against cardiovascular disease, but studies show quite different effects on specific conditions such as coronary heart disease or cerebrovascular disease. A priori dietary indexes used to measure dietary exposure imply quantitative and/or qualitative divergences from the traditional Mediterranean Diet of the early 1960s, and, therefore, it is very difficult to compare the results of different studies. Based on real cultural heritage and traditions, we believe that the a priori indexes used to evaluate adherence to the Mediterranean Diet should consider classifying whole grains and refined grains, olive oil and monounsaturated fats, and wine and alcohol differently.

Abstract
CONTEXT Alcohol dependence can lead to autonomic neuropathy resulting in increased cardiac morbidity and mortality. This has previously been evaluated using heart-rate variability. AIMS We compared sleep heart-rate variability of alcohol-dependent patients with that of healthy controls in this study. SETTINGS AND DESIGN This study was conducted at NIMHANS, Bangalore. A case control study design was adopted. MATERIALS AND METHODS Sleep heart-rate variability of 20 male alcohol-dependent inpatients was recorded on the 5(th) day after detoxification. Sleep heart-rate variability was also recorded in 18 age- and gender-matched healthy controls. STATISTICAL ANALYSIS The groups were compared using t-test for continuous variables and Chi-squared test for discrete variables. RESULTS Both time and frequency domain measures were significantly lower in the patients as compared to the controls, indicating decreased HRV in alcohol-dependent individuals. CONCLUSIONS Decreased HRV in alcohol dependence indicates potential autonomic neuropathy.

Abstract
AIMS Most, but not all, epidemiological studies suggest a cardioprotective association for low to moderate average alcohol consumption. The objective was to quantify the dose-response relationship between average alcohol consumption and ischaemic heart disease (IHD) stratified by sex and IHD end-point (mortality versus morbidity). METHODS A systematic search of published studies using electronic databases (1980-2010) identified 44 observational studies (case-control or cohort) reporting a relative risk measure for average alcohol intake in relation to IHD risk. Generalized least-squares trend models were used to derive the best-fitting dose-response curves in stratified continuous meta-analyses. Categorical meta-analyses were used to verify uncertainty for low to moderate levels of consumption in comparison to long-term abstainers. RESULTS The analyses used 38,627 IHD events (mortality or morbidity) among 957,684 participants. Differential risk curves were found by sex and end-point. Although some form of a cardioprotective association was confirmed in all strata, substantial heterogeneity across studies remained unexplained and confidence intervals were relatively wide, in particular for average consumption of one to two drinks/day. CONCLUSIONS A cardioprotective association between alcohol use and ischaemic heart disease cannot be assumed for all drinkers, even at low levels of intake. More evidence on the overall benefit-risk ratio of average alcohol consumption in relation to ischaemic heart disease and other diseases is needed in order to inform the general public or physicians about safe or low-risk drinking levels.

Abstract
UNLABELLED Obesity is an ongoing worldwide epidemic. Besides being a medical condition in itself, obesity dramatically increases the risk of development of metabolic and cardiovascular disease. This risk appears to stem from multiple abnormalities in adipose tissue function leading to a chronic inflammatory state and to dysregulation of the endocrine and paracrine actions of adipocyte-derived factors. These, in turn, disrupt vascular homeostasis by causing an imbalance between the NO pathway and the endothelin 1 system, with impaired insulin-stimulated endothelium-dependent vasodilation. Importantly, emerging evidence suggests that the vascular dysfunction of obesity is not just limited to the endothelium, but also involves the other layers of the vessel wall. In particular, obesity-related changes in medial smooth muscle cells seem to disrupt the physiological facilitatory action of insulin on the responsiveness to vasodilator stimuli, whereas the adventitia and perivascular fat appear to be a source of pro-inflammatory and vasoactive factors that may contribute to endothelial and smooth muscle cell dysfunction, and to the pathogenesis of vascular disease. While obesity-induced vascular dysfunction appears to be reversible, at least in part, with weight control strategies, these have not proved sufficient to prevent the metabolic and cardiovascular complication of obesity on a large scale. While a number of currently available drugs have shown potentially beneficial vascular effects in patients with obesity and the metabolic syndrome, elucidation of the pathophysiological mechanisms underlying vascular damage in obese patients is necessary to identify additional pharmacologic targets to prevent the cardiovascular complications of obesity, and their human and economic costs.

Abstract
BACKGROUND Studies have found that higher levels of cardiorespiratory fitness and light to moderate alcohol intake reduce the risk for premature death. Scant evidence, however, exists assessing the joint effects of both measures on all-cause and cardiovascular disease (CVD) mortality. PURPOSE This study aims to examine the independent and joint effects of alcohol consumption and cardiorespiratory fitness on all-cause and cardiovascular-related mortality in a large cohort of men. METHODS This prospective study included 29,402 men who came to the Cooper Clinic (Dallas, TX) for a preventive medicine visit from 1973 to 2006. Data were analyzed in 2011. The primary exposure variables were tertiles of cardiorespiratory fitness and four categories of alcohol consumption, and the outcomes were all-cause and CVD mortality. Cox proportional hazards regression was used to model the association between alcohol intake, cardiorespiratory fitness, and all-cause and CVD mortality, controlling for potential confounders. RESULTS A total of 1830 (all-cause) and 523 (CVD) deaths occurred in men over an average follow-up period of 17.4 years (SD=9.1). A linear relationship was observed (p<0.001) between increased fitness and reduced all-cause and CVD mortality. Specifically, moderate and high levels of fitness reduced the risk for all-cause mortality (HR=0.67, 95% CI=0.60, 0.74, and HR=0.57, 95% CI=0.49, 0.67, respectively) and CVD mortality in comparison to the low-fitness reference group (HR=0.70, 95% CI=0.57, 0.85; HR=0.54, 95% CI=0.40, 0.75, respectively), while controlling for alcohol intake and other covariates. A significant curvilinear relationship was found (p=0.01) between alcohol intake and all-cause mortality (but not CVD mortality), while controlling for fitness and other covariates. In a categoric examination of alcohol intake and mortality, adjusting for fitness and other confounders, there was no statistically significant effect of light drinking compared to heavy drinking on all-cause mortality or CVD mortality. An examination of the joint effects of fitness and alcohol on all-cause mortality showed that moderate and high fitness levels were protective against mortality irrespective of alcohol consumption levels. Few significant combined effects for CVD mortality reduction were found. CONCLUSIONS Alcohol consumption did not significantly modify the association between fitness and mortality in this large cohort of men.

Abstract
Resveratrol (RSVL), a polyphenolic compound found in red wine is believed to be a contributor in decreasing the incidence of coronary heart disease. Although its primary target is unknown, it blocks platelet aggregation by an ill-defined mechanism. Protein kinase C (PKC), which would redistribute from the cytosol to the platelet membrane upon platelet stimulation, plays a key role in the signal transduction system of platelets in human. In this study, we investigated the effect of RSVL and a PKC inhibitor (DL-erythro-1,3-Dihydroxy-2-aminooctadecane, PKCI) on platelet aggregation induced by a thromboxane A2receptor agonist (U46619, 9,11-Dideoxy-11α, 9α-epoxymethanoprostaglandin F2α) using a platelet aggregometer. We also studied the platelet membranebound fibrinogen (PFig) content and the activity of protein kinase C (PKC) in platelets from healthy volunteers using flow cytometry, and a phosphorimaging system, respectively. Our results showed that RSVL blocked platelet aggregation and PFig content induced by U46619 in a concentration-dependent manner. PKCI and RSVL had an additive effect in inhibiting platelet aggregation and PFig content. Furthermore, RSVL (final concentration 50 μM) remarkably depressed the activity of PKC in the membrane of platelets and the percentage of membrane PKC activity in total PKC activity. Taken together, these results suggested that RSVL suppressed U46619-induced platelet aggregation and PFig content partially through the inhibition of the activity of PKC in platelets.

Abstract
OBJECTIVE To examine gender differentials in the association between life course socioeconomic disadvantage and the risk of exceeding internationally recognised weekly and daily guidelines for 'sensible' alcohol consumption and problem drinking. METHODS A population-representative cohort study of 1,218 men and women from the west of Scotland, UK was conducted. Data on life course socioeconomic position were collected in 1987/1988 (at around 35 years of age). Alcohol consumption patterns (detailed 7-day recall) and problem drinking (CAGE questionnaire) were ascertained in 1990/1992. RESULTS There was evidence of marked gender divergence in the socioeconomic position-alcohol intake/problem gradients. Typically, disadvantage in men conferred an increased risk of exceeding 'sensible' guidelines for weekly consumption (for own education and adult social class) and having alcohol problems (for employment status, income, adult social class and car ownership). In contrast, a reverse gradient was evident in women where adverse social status was generally associated with a reduced prevalence of these outcomes. CONCLUSION Investigators should consider more carefully socioeconomic patterning of alcohol intake, and possibly other health-related behaviours, separately in men and women.

A cross sectional study. BMC Public Health 2011; 11:259. [PMID: 21513542 PMCID: PMC3123204 DOI: 10.1186/1471-2458-11-259] [Citation(s) in RCA: 15] [Impact Index Per Article: 1.2] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/23/2010] [Accepted: 04/23/2011] [Indexed: 11/12/2022] Open
Abstract
BACKGROUND As the promotion of alcohol and tobacco to young people through direct advertising has become increasingly restricted, there has been greater interest in whether images of certain behaviours in films are associated with uptake of those behaviours in young people. Associations have been reported between exposure to smoking images in films and smoking initiation, and between exposure to film alcohol images and initiation of alcohol consumption, in younger adolescents in the USA and Germany. To date no studies have reported on film images of recreational drug use and young people's own drug use. METHODS Cross sectional multivariable logistic regression analysis of data collected at age 19 (2002-4) from a cohort of young people (502 boys, 500 girls) previously surveyed at ages 11 (in 1994-5), 13 and 15 in schools in the West of Scotland. Outcome measures at age 19 were: exceeding the 'sensible drinking' guidelines ('heavy drinkers') and binge drinking (based on alcohol consumption reported in last week), and ever use of cannabis and of 'hard' drugs. The principle predictor variables were an estimate of exposure to images of alcohol, and of drug use, in films, controlling for factors related to the uptake of substance use in young people. RESULTS A third of these young adults (33%) were classed as 'heavy drinkers' and half (47%) as 'binge drinkers' on the basis of their previous week's consumption. Over half (56%) reported ever use of cannabis and 13% ever use of one or more of the 'hard' drugs listed. There were linear trends in the percentage of heavy drinkers (p = .018) and binge drinkers (p = 0.012) by film alcohol exposure quartiles, and for ever use of cannabis by film drug exposure (p = .000), and for ever use of 'hard' drugs (p = .033). The odds ratios for heavy drinking (1.56, 95% CI 1.06-2.29 comparing highest with lowest quartile of film alcohol exposure) and binge drinking (1.59, 95% CI 1.10-2.30) were attenuated by adjustment for gender, social class, family background (parental structure, parental care and parental control), attitudes to risk-taking and rule-breaking, and qualifications (OR heavy drinking 1.42, 95% CI 0.95-2.13 and binge drinking 1.49, 95% CI 1.01-2.19), and further so when adjusting for friends' drinking status (when the odds ratios were no longer significant). A similar pattern was seen for ever use of cannabis and 'hard' drugs (unadjusted OR 1.80, 95% CI 1.24-2.62 and 1.57, 95% CI 0.91-2.69 respectively, 'fully' adjusted OR 1.41 (0.90-2.22 and 1.28 (0.66-2.47) respectively). CONCLUSIONS Despite some limitations, which are discussed, these cross-sectional results add to a body of work which suggests that it is important to design good longitudinal studies which can determine whether exposure to images of potentially health-damaging behaviours lead to uptake of these behaviours during adolescence and early adulthood, and to examine factors that might mediate this relationship.

Abstract
Current abstainers from alcohol have been identified as an inadequate reference group in epidemiologic studies of the effects of alcohol, because inclusion of former drinkers might lead to overestimation of the protective effects and underestimation of the detrimental effects of drinking alcohol. The authors' objective in the current study was to quantify this association for ischemic heart disease (IHD). Electronic databases were systematically searched for relevant case-control or cohort studies published from 1980 to 2010. Thirty-eight articles fulfilled the inclusion criteria, contributing a total of 5,613 IHD events and 12,097 controls among case-control studies and 1,387 events with combined endpoints and 7,183 events stratified by endpoint among 232,621 persons at risk among cohort studies. Pooled estimates for the subset stratified by sex and endpoint showed a significantly increased risk among former drinkers compared with long-term abstainers for IHD mortality ( among men; relative risk = 1.25, 95% confidence interval: 1.15, 1.36; among women relative risk = 1.54, 95% confidence interval: 1.17, 2.03). For IHD morbidity, the estimates for both sexes were close to unity and not statistically significant. Results were robust in several sensitivity analyses. In future studies, researchers should separate former drinkers from the reference category to obtain unbiased effect estimates. Implications for the overall beneficial and detrimental effects of alcohol consumption on IHD are discussed below.

Abstract
The metabolic syndrome is becoming increasingly prevalent in the general population and carries significant incremental morbidity and mortality. It is associated with multi-organ involvement and increased all-cause mortality, resembling a precocious aging process. The mechanisms that account for this phenomenon are incompletely known, but it is becoming clear that longevity genes might be involved. Experiments with overactivation or disruption of key lifespan determinant pathways, such as silent information regulator (SIR)T1, p66Shc, and mammalian target of rapamycin (TOR), lead to development of features of the metabolic syndrome in mice. These genes integrate longevity pathways and metabolic signals in a complex interplay in which lifespan appears to be strictly dependent on substrate and energy bioavailability. Herein, we describe the roles and possible interconnections of selected lifespan determinant molecular networks in the development of the metabolic syndrome and its complications, describing initial available data in humans. Additional pathways are involved in linking nutrient availability and longevity, certainly including insulin and Insulin-like Growth Factor-1 (IGF-1) signaling, as well as FOXO transcription factors. The model described in this viewpoint article is therefore likely to be an oversimplification. Nevertheless, it represents one starting platform for understanding cell biology of lifespan in relation to the metabolic syndrome.

Abstract
Resveratrol (3,4',5-trihydroxystilbene) is a member of natural, plant-derived chemicals known as polyphenols and is attracting increased attention due to its diverse health benefits especially in case of cardiovascular disease, cancer, diabetes and neurological problems. Despite impressive gains in diagnosis and treatment, cardiovascular disease (CVD) remains a serious clinical problem and threat to public health. Resveratrol possesses potent antioxidant properties and has been shown to decrease low-density lipoprotein-cholesterol oxidation and platelet aggregation. This compound also possesses a range of additional cardioprotective and vasoprotective properties including antiatherosclerotic and vasorelaxation action. Resveratrol also has the capacity to interact with multiple molecular targets, which involve diverse intracellular pathways. Most well-known is the ability of resveratrol to activate sirtuins, a class of NAD(+)-dependent deacetylase that affect multiple transcription factors and other protein targets. Recently, resveratrol was found to induce autophagy and regenerate myocardial ischemic tissue treated with stem cells. Overall observation indicates that resveratrol has a high therapeutic potentials for the treatment of cardiovascular diseases.

Abstract
OBJECTIVE Waist circumference, BMI and hip circumference are differentially associated with mortality. We investigated the potential influence of selected lifestyle aspects such as smoking, alcohol intake, sports activity and education. METHOD The Danish prospective study 'Diet, Cancer and Health' recruited 27,179 men and 29,875 women from 1993 to 1997. Cox regression models were used to estimate mortality rate ratios. RESULTS Adjustment for smoking habits attenuated the associations between mortality and the three body size measurements in both sexes. Adjustment for sport activity and, to a lesser extent, alcohol intake weakened the associations further for the men, whereas alcohol intake slightly weakened associations for the women. In the fully adjusted models, mortality increased highly significantly with higher waist circumference and lower hip circumference, and decreased highly significantly with higher BMI for BMI below 25 kg/m(2). This pattern was seen for all levels of the selected lifestyle factor. CONCLUSION A large waist circumference remained a strong risk indicator for mortality, and a large hip circumference appeared to be protective when smoking habits, alcohol intake and sport activity were accounted for. BMI below 25 kg/m(2) remained a risk factor, but not above 25 kg/m(2) once waist circumference was adjusted for.

Abstract
It is well known that the consumption of dietary polyphenols leads to beneficial effects for human health as in the case of prevention and/or attenuation of cardiovascular, inflammatory, neurodegenerative and neoplastic diseases. This review summarizes the role of polyphenols from red wine in the immune function. In particular, using healthy human peripheral blood mononuclear cells, we have demonstrated the in vitro ability of Negroamaro, an Italian red wine, to induce the release of nitric oxide and both pro-inflammatory and anti-inflammatory cytokines, thus leading to the maintenance of the immmune homeostasis in the host. All these effects were abrogated by deprivation of polyphenols from red wine samples. We have also provided evidence that Negromaro polyphenols are able to activate extracellular regulated kinase and p38 kinase and switch off the NF-kappaB pathway via an increased expression with time of the IkappaBalpha phosphorylated form. These mechanisms may represent key molecular events leading to inhibition of the pro-inflammatory cascade and atherogenesis. In conclusion, according to the current literature and our own data, moderate consumption of red wine seems to be protective for the host in the prevention of several diseases, even including aged-related diseases by virtue of its immunomodulating properties.

Abstract
BACKGROUND The health and social impact of drinking in excess of internationally recognized weekly (>21 units in men; >14 units in women) and daily (>4 units in men; >3 units in women) recommendations for 'sensible' alcohol intake are largely unknown. METHODS A prospective cohort study of 1551 men and women aged around 55 years in 1988 when typical alcohol consumption was recalled using a 7-day grid. An average of 3.4 years later (1990/92), study participants were re-surveyed (n = 1259; 84.7% of the target population) when they responded to nurse-administered enquiries regarding minor psychiatric morbidity, self-perceived health, hypertension, accidents, overweight/obesity and financial difficulties. Study members were followed up for mortality experience over 18 years. RESULTS In fully adjusted analyses, surpassing guidelines for sensible alcohol intake was associated with an increased risk of hypertension [daily guidelines only: P-value(trend): 0.012], financial problems [weekly guidelines: P-value(difference): 0.046] and, to a lesser degree, accidents [weekly guidelines: P-value(difference): 0.065]. There was no association between either indicator of alcohol intake and mortality risk. CONCLUSIONS In the present study, there was some evidence for a detrimental effect on health and social circumstances of exceeding current internationally recognized weekly and daily guidelines for alcohol intake.

Abstract
Although excessive consumption of ethanol in alcoholic beverages causes multi-organ damage, moderate consumption, particularly of red wine, is protective against all-cause mortality. These protective effects could be due to one or many components of the complex mixture of bioactive compounds present in red wine including flavonols, monomeric and polymeric flavan-3-ols, highly colored anthocyanins as well as phenolic acids and the stilbene polyphenol, resveratrol. The therapeutic potential of resveratrol, firstly in cancer chemoprevention and then later for cardioprotection, has stimulated many studies on the possible mechanisms of action. Further indications for resveratrol have been developed, including the prevention of age-related disorders such as neurodegenerative diseases, inflammation, diabetes, and cardiovascular disease. These improvements are remarkably similar yet there is an important dichotomy: low doses improve cell survival as in cardio- and neuro-protection yet high doses increase cell death as in cancer treatment. Fewer studies have examined the responses to other components of red wine, but the results have, in general, been similar to resveratrol. If the nonalcoholic constitutents of red wine are to become therapeutic agents, their ability to get to the sites of action needs to be understood. This mini-review summarizes recent studies on the possible mechanisms of action, potential therapeutic uses, and bioavailability of the nonalcoholic constituents of alcoholic beverages, in particular resveratrol and other polyphenols.

Abstract
The cerebral neuropathology of Type 2 diabetes (CNDM2) has not been positively defined. This review includes a description of CNDM2 research from before the 'Pubmed Era'. Recent neuroimaging studies have focused on cerebrovascular and white matter pathology. These and prior studies about cerebrovascular histopathology in diabetes are reviewed. Evidence is also described for and against the link between CNDM2 and Alzheimer's disease pathogenesis. To study this matter directly, we evaluated data from University of Kentucky Alzheimer's Disease Center (UK ADC) patients recruited while non-demented and followed longitudinally. Of patients who had come to autopsy (N = 234), 139 met inclusion criteria. These patients provided the basis for comparing the prevalence of pathological and clinical indices between well-characterized cases with (N = 50) or without (N = 89) the premortem diagnosis of diabetes. In diabetics, cerebrovascular pathology was more frequent and Alzheimer-type pathology was less frequent than in non-diabetics. Finally, a series of photomicrographs demonstrates histopathological features (including clinical-radiographical correlation) observed in brains of persons that died after a history of diabetes. These preliminary, correlative, and descriptive studies may help develop new hypotheses about CNDM2. We conclude that more work should be performed on human material in the context of CNDM2.

Alcohol problems and all-cause mortality in men and women: predictive capacity of a clinical screening tool in a 21-year follow-up of a large, UK-wide, general population-based survey. J Psychosom Res 2009; 66:317-21.

Abstract
OBJECTIVE While the relation between alcohol consumption and mortality has been well explored, little is known about the link between alcohol problems and mortality in general population-based studies, particularly among women. This was the objective of the present study METHODS In this prospective cohort study, 5333 non-abstaining individuals (2539 women) from the UK-wide Health and Lifestyle Survey (aged 42.9 years at study induction) completed the CAGE questionnaire of alcohol problems and participated in a medical examination in 1984/1985; they were then followed up for mortality experience until 2005. RESULTS Alcohol problems at baseline were less common in women (2.4%) than in men (7.8%). A total of 21 years of follow-up gave rise to 1201 deaths. Elevated rates of mortality were evident in persons reporting symptoms of alcohol problems in comparison to those who did not. In gender-stratified analyses, alcohol problems were more strongly associated with mortality risk in women (age-adjusted hazards ratio: 2.25; 95% confidence interval: 1.22-4.12) than in men (1.49; 1.12-1.99), although this effect modification was not statistically significant (P value for interaction=0.125). Controlling for a range of covariates--including socioeconomic position, co-morbidity (somatic and psychiatric), and alcohol intake--had essentially no impact on these associations. CONCLUSION The CAGE questionnaire may have some utility in routine health assessments in the general population.

Abstract
Moderate alcohol consumption is suggested to be associated with reduced inflammation and morbidity. Human adipose tissue (AT) and obesity is characterised by low-grade inflammation, so the present study wanted to investigate the effects of ethanol on inflammation in human AT in vitro. Subcutaneous human AT was incubated with ethanol [11-88 mM] under non- or LPS-stimulated [50mg/mL] conditions. Protein and mRNA levels of adiponectin, IL-6, IL-8, TNF-alpha, MCP-1, and CD68 were assessed using ELISA and real-time RT-PCR, respectively. Non-stimulated, ethanol incubations up to 24h increased adiponectin release and mRNA expression (p<0.01) and decreased IL-6 release in both short-term [1.5h] (p<0.05) and long-term [24h] (p<0.01) incubations. Ethanol decreased LPS-stimulated IL-6, IL-8, TNF-alpha, and MCP-1 dose-dependently (all p<0.01). Ethanol decreased CD68 mRNA (p<0.001), which correlated with the investigated adipokines (p<0.05) but not adiponectin (p>0.05). In conclusion, ethanol exerts anti-inflammatory effects in human AT, suggesting that ethanol may attenuate whole-body inflammation.

Abstract
BACKGROUND Moderate alcohol use is generally associated with lower ischaemic heart disease (IHD) mortality but it is difficult to ascertain whether this is due to attributes of moderate alcohol users or the properties of alcohol itself. Evidence from populations with different patterns of alcohol use and IHD can provide crucial evidence. We assessed the association of moderate alcohol use with IHD mortality in older Chinese people from Hong Kong. METHODOLOGY We used Cox regression to determine whether moderate alcohol use was associated with IHD mortality in a prospective, population-based cohort study of all 56,167 attendees, aged 65 years or over, from July 1998 to December 2000 at all 18 Elderly Health Centers operated by the Department of Health in Hong Kong. PRINCIPAL FINDINGS After a median follow-up of 4.2 years, there were 406 (188 in men, 218 in women) deaths from IHD in 54,090 subjects (96.3% successful follow-up). Moderate alcohol use in men was not associated with IHD mortality adjusted only for age [Hazard Ratio, HR 1.01 (95% CI 0.55 to 1.84) compared with never drinkers] or additionally adjusted for socio-economic status and lifestyle. Almost all women were occasional drinkers and their current alcohol use was not significantly associated with IHD mortality [HR 0.88, (95% CI 0.51 to 1.53)]. CONCLUSIONS Moderate alcohol use had no effect on IHD mortality in older Chinese men. Lack of replication of the usual protective effect of moderate alcohol use in a setting with a different pattern of alcohol use and IHD could be due to chance or could suggest that the protective effect of alcohol on IHD does not extend to all populations.

Abstract
BACKGROUND AND AIMS Coronary disease (CHD)-related hospital admission is more common among indigenous than non-indigenous Australians. We aimed to identify predictors of hospital admission potentially useful in planning prevention programs. METHODS AND RESULTS Length of stay (LOS), interval between, and number of recurrent admissions were modelled with proportional hazards or negative binomial models using lifestyle data recorded in 1988-1989 among Aborigines (256 women, 258 men, aged 15-88years) linked to hospital records to 2002. Among 106 Aborigines with CHD, hypertension (hazard ratio (HR) 1.69, 95% CI 1.05-2.73); smoking (HR 1.90, 95% CI 1.02-3.53); consuming processed meat >4 times/month (HR 1.81, 95% CI 1.01-3.24); >6 eggs/week (HR 1.73, 95% CI 1.03-2.94); and lower intake of alcohol (HR 0.54, 95% CI 0.35-0.83) predicted LOS. Eating eggs (HR 1.05, 95% CI 1.01-1.09) and bush meats > or =7 times/month (HR 0.46, 95% CI 0.23-0.92) predicted interval between recurrent admissions. Hypertension (IRR 4.07; 95% CI 1.32-12.52), being an ex-drinker (IRR 6.60, 95% CI 2.30-19.00), eating red meat >6 times/week (IRR 0.98, 95% CI 0.97-0.99), bush meats >7 times/month (IRR 0.26, 95% CI 0.10-0.67), and adding salt to meals (IRR 3.16, 95% CI 1.12-8.92) predicted number of admissions. CONCLUSION Hypertension, alcohol drinking, smoking, and diet influence hospital admissions for CHD in Aboriginal Australians.

Abstract
Resveratrol, an antioxidant polyphenol from red wine, has been the subject of intense interest in recent years due to a range of unique anti-aging properties. These include cardiovascular benefits via increased nitric oxide production, down-regulation of vasoactive peptides, lowered levels of oxidized low-density lipoprotein, and cyclooxygenase inhibition; possible benefits on Alzheimer's disease by breakdown of beta-amyloid and direct effects on neural tissues; phytohormonal actions; anticancer properties via modulation of signal transduction, which translates into anti-initiation, antipromotion, and antiprogression effects; antimicrobial effects; and sirtuin activation, which is believed to be involved in the caloric restriction-longevity effect. Here we report a resveratrol-based skin care formulation, with 17 times greater antioxidant activity than idebenone. The role of resveratrol in prevention of photoaging is reviewed and compared with other antioxidants used in skin care products.

Abstract
PURPOSE Moderate alcohol use is part of a healthy lifestyle, yet current guidelines caution nondrinkers against starting to drink alcohol in middle age. The purpose of this study was to evaluate whether adopting moderate alcohol consumption in middle age would result in subsequent lower cardiovascular risk. METHODS This study examined a cohort of adults aged 45-64 years participating in the Atherosclerosis Risk in Communities study over a 10-year period. The primary outcome was fatal or nonfatal cardiovascular events. RESULTS Of 7697 participants who had no history of cardiovascular disease and were nondrinkers at baseline, within a 6-year follow-up period, 6.0% began moderate alcohol consumption (2 drinks per day or fewer for men, 1 drink per day or fewer for women) and 0.4% began heavier drinking. After 4 years of follow-up, new moderate drinkers had a 38% lower chance of developing cardiovascular disease than did their persistently nondrinking counterparts. This difference persisted after adjustment for demographic and cardiovascular risk factors (odds ratio 0.62, 95% confidence interval, 0.40-0.95). There was no difference in all-cause mortality between the new drinkers and persistent nondrinkers (odds ratio 0.71, 95% confidence interval, 0.31-1.64). CONCLUSION People who newly begin consuming alcohol in middle age rarely do so beyond recommended amounts. Those who begin drinking moderately experience a relatively prompt benefit of lower rates of cardiovascular disease morbidity with no change in mortality rates after 4 years.

Abstract
BACKGROUND Ethanol's ability to inhibit gluconeogenesis might reduce postprandial glycemia in realistic meal settings. OBJECTIVE The objective was to explore the effect of 3 types of alcoholic beverages consumed alone, with a meal, or 1 h before a meal on postprandial glycemia in healthy subjects. DESIGN In study 1, isoenergetic (1000 kJ) servings of beer, white wine, and gin were compared with a 1000-kJ portion of white bread. In study 2, the same servings were compared with water as an accompaniment to a bread meal. In study 3, 20-g alcohol portions were served as a premeal drink. Fingertip capillary blood samples were taken at regular intervals over 2-3 h. RESULTS In study 1, the mean (+/-SE) glucose scores for beer (58 +/- 11), wine (7 +/- 3), and gin (10 +/- 5) were significantly lower (P < 0.001) than those for bread (= 100). In study 2, meals consumed with beer (84 +/- 11; P = 0.03), wine (63 +/- 6; P < 0.001), and gin (80 +/- 12; P = 0.007) produced less glycemia than did the meal consumed with water (= 100). In study 3, all 3 beverages reduced the postprandial glycemic response to the subsequent meal (67 +/- 5, 75 +/- 6, and 78 +/- 4 with the beer, wine, and gin trials, respectively; P < 0.003). CONCLUSION In realistic settings, alcoholic beverage consumption lowers postprandial glycemia by 16-37%, which represents an unrecognized mechanism by which alcohol may reduce the risk of chronic disease.

Abstract
BACKGROUND modifiable behavioural risk factors including smoking and alcohol consumption are major contributing or actual causes of mortality. OBJECTIVE to examine the effect of alcohol intake on all-cause mortality in older adults. DESIGN AND SETTING prospective population-based cohort study of residents of a California, United States retirement community. SUBJECTS 8,877 women and 5,101 men (median age, 74 years) who in the early 1980s completed a postal health srvey incluing details on alcohol consumption. METHODS participants were followed for 23 years (1981-2004) including two follow-up questionnaires (in 1992 and 1998) asking about current alcohol intake. Age-adjusted and multivariate-adjusted risk ratios of death and 95% confidence intervals were calculated separately for men and women, using proportional hazard regression. RESULTS of the 8,644 women and 4,980 men with complete information on the variables of interest and potential confounders, 6,930 women and 4,456 men had died (median age, 87 years). Both men and women who drank alcohol had decreased mortality compared with non-drinkers. Those who drank two or more drinks per day had a 15% reduced risk of death. The reduced risk was not limited to one type of alcohol. Stable drinkers (those who reported drinking both at baseline and follow-up) had a significantly decreased risk of death compared with stable non-drinkers. Those who started drinking at follow-up also had a significantly lower risk. Women who quit drinking were at increased risk of death. CONCLUSION in elderly men and women, moderate alcohol intake exhibits a beneficial effect on mortality. Those who quit may do so for health reasons that affect mortality.

Abstract
In support of the 2005 update of the U.S. Department of Agriculture/U.S. Department of Health and Human Services Dietary Guidelines, the National Institute on Alcohol Abuse and Alcoholism was asked to assess the strength of the evidence related to health risks and potential benefits of moderate alcohol consumption, with particular focus on the areas of cardiovascular disease, breast cancer, obesity, birth defects, breastfeeding, and aging. The findings were reviewed by external researchers with extensive research backgrounds on the consequences and benefits of alcohol consumption. This report now serves as the National Institutes of Health's formal position paper on the health risks and potential benefits of moderate alcohol use.

Abstract
Emerging evidence suggests that diet quality indices may serve as prognostic indicators of disease. However, the ability of these indices to predict breast cancer risk has not been evaluated previously. We assessed the association between several diet quality scores and the risk of breast cancer in postmenopausal women. The indices we used were the Healthy Eating Index (HEI), Alternate Healthy Eating Index (AHEI), Diet Quality Index-Revised (DQI-R), Recommended Food Score (RFS), and the alternate Mediterranean Diet Score (aMed). We calculated diet quality indices from dietary information collected in FFQ administered 5 times between 1984 and 1998 among women in the Nurses' Health Study cohort. Relative risks (RR) were computed using Cox proportional hazards models and adjusted for known risk factors for breast cancer. Separate analyses were conducted for estrogen receptor positive (ER+) and negative (ER-) tumors. Between 1984 and 2002, we documented 3,580 cases of breast cancer, of which 2,367 were ER+, and 575 were ER-. We did not observe any association between the diet quality indices and total or ER+ breast cancer risk. However, for ER- breast cancer, after adjusting for potential confounders, the RR comparing highest to lowest quintiles were 0.78 (95% CI=0.59-1.04, P for trend=0.01) for the AHEI, 0.69 (95% CI=0.51-0.94, P for trend=0.003) for the RFS, and 0.79 (95% CI=0.60-1.03, P for trend=0.03) for the aMed. These observations appeared to be the result of an inverse association (P for trend=0.01) with the vegetable component of the scores. We conclude that women who scored high in AHEI, RFS, and aMed had a lower risk of ER- breast cancer. The HEI and DQI-R appeared to be of limited value in predicting breast cancer risk.

Abstract
Previous investigations have shown a biphasic effect of alcohol on blood pressure (BP). However, there are no studies on possible simultaneous influences in endothelial function. This study aims to evaluate the early and late effects of alcohol ingestion on vascular and endothelial function parameters in healthy young men. The diameter of brachial artery (DBA), endothelium-dependent flow-mediated dilatation, endothelium-independent nitroglycerin-mediated dilatation, systolic blood pressure (SBP), diastolic blood pressure (DBP), and heart rate were measured 30 min before intake, 4 h after intervention (when there is a reported hypotensive effect of alcohol), and after 13 h (subsequent increase in BP). The study group consisted of 100 males aged 18-25 years who were evaluated by brachial artery ultrasound. Subjects were randomized to drink either an alcoholic (60 g of ethanol) or a similar nonalcoholic beverage. Alcohol induced a biphasic effect on SBP and DBP, with a 4-h decrease followed by an increase after 13 h. After 4 h, the alcohol-drinking group presented a DBA increase that was significant at baseline and after hyperemia but not after nitroglycerin administration. There were no DBA differences between the intervention and control groups 13 h after drinking. This study replicates the initial reports of alcohol-induced biphasic alteration in BP. Our results showed that despite the late increase in BP, there were no accompanying changes in endothelial function.

Abstract
Complications of atherosclerosis remain the leading cause of morbidity and mortality in industrialized countries. Epidemiological studies have repeatedly demonstrated that moderate alcohol intake has a beneficial effect on cardiovascular disease. The purpose of this review is to examine the epidemiological and biological evidence supporting the intake of red wine as a means of reducing atherosclerosis. On the basis of epidemiological studies, moderate intake of alcoholic beverages, including red wine, reduces the risk of cardiovascular, cerebrovascular, and peripheral vascular disease in populations. In addition to the favorable biological effects of alcohol on the lipid profile, on hemostatic factors, and in reducing insulin resistance, the phenolic compounds in red wine appear to interfere with the molecular processes underlying the initiation, progression, and rupture of atherosclerotic plaques. Whether red wine is more beneficial than other types of alcohol remains unclear. Definitive data from a large-scale, randomized clinical end-point trial of red wine intake would be required before physicians can advise patients to use wine as part of preventative or medical therapies.

Abstract
OBJECTIVE To test the hypothesis that alcohol consumption is positively related to heart rate variability (HRV) in women with coronary heart disease (CHD) and therefore that cardiac autonomic activity is potentially implicated in the mediation of the favourable effects of moderate drinking. DESIGN, SETTINGS, AND PATIENTS Cross sectional study of female patients who survived hospitalisation for acute myocardial infarction or underwent a revascularisation procedure, percutaneous transluminal coronary angioplasty, or coronary artery bypass grafting. MAIN OUTCOME MEASURES Ambulatory 24 hour ECG was recorded during normal activities. The mean of the standard deviations of all normal to normal intervals for all five minute segments of the entire recording (SDNNI) and the following frequency domain parameters were assessed: total power, high frequency power, low frequency power, and very low frequency power. A standardised questionnaire evaluated self reported consumption of individual alcoholic beverage types: beer, wine, and spirits. Other clinical characteristics, such as age, body mass index, smoking habits, history of diabetes mellitus, menopausal status, educational status, and treatment, were also assessed. RESULTS Wine intake was associated with increased HRV in both time and frequency domains independently of other clinical covariates (for example, ln SDNNI was 3.89 among wine drinkers v 3.59 among wine non-drinkers in the multivariate model; p = 0.014). In contrast, consumption of beer and spirits and the total amount of alcohol consumed did not relate significantly to any of the HRV parameters. CONCLUSION Intake of wine, but not of spirits or beer, is positively and independently associated with HRV in women with CHD. These results may contribute to the understanding of the complex relation between alcohol consumption and CHD.

Abstract
Background—
Current paradigm attributes the low incidence of cardiovascular disorders in Mediterranean countries despite a high saturated fat intake, the “French paradox,” to the antioxidant capacity of red wine polyphenols. Conceivably, other antiinflammatory pathways may contribute to at least a similar extent to the atheroprotective activity of these polyphenols. We have investigated whether gallic acid (GA), an abundant red wine polyphenol, modulates the activity of P-selectin, an adhesion molecule that is critically involved in the recruitment of inflammatory cells to the vessel wall and thus in atherosclerosis.
Methods and Results—
GA potently inhibited the binding of a peptide antagonist (IC

, 7.2 μmol/L) and biotin-PAA-Le
a

H, an established high-affinity ligand, to P-selectin (IC

, 85 μmol/L). Under dynamic flow conditions, GA markedly and dose dependently attenuated the rolling of monocytic HL60 cells over P-selectin-transfected Chinese hamster ovary cells (EC
50
, 14.5 μmol/L) while increasing the velocity of P-selectin-dependent rolling of human blood leukocytes over a platelet monolayer. In vivo tests established that GA administration to normolipidemic C57/Bl6 and aged atherosclerotic apolipoprotein E–deficient mice impaired the baseline rolling of conjugates between activated platelets and circulating monocytes over femoral vein endothelium, as judged by online video microscopy (ED

Conclusions—
Our findings provide a solid mechanistic foundation through which GA intervenes in major inflammatory pathobiologies by binding and antagonizing P-selectin.

JOURNAL OF BIOCHEMICAL AND BIOPHYSICAL METHODS 2004; 61:169-82. [PMID: 15560933 DOI: 10.1016/j.jbbm.2004.06.007] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 11/04/2003] [Revised: 04/23/2004] [Accepted: 06/19/2004] [Indexed: 05/01/2023]
Abstract
In the current study, seven Styrian white wine varieties, as well as their corresponding grape skin extracts (GSE), were tested for possible antagonistic effects on several endogenous vasoconstrictors known to be involved in the pathogenesis of cardiovascular diseases via tissue contraction experiments. Results were compared to those of Zweigelt, the most cultivated Styrian red wine. Bovine coronary artery strips were attached to a force transducer connected to a bridge amplifier, and isometric force was recorded on a multipen recorder. Preincubation of the vessels with the dealcoholized wines (DAW; 330 microl/ml) inhibited the constrictions to histamine and serotonin (5-HT) NO-dependently in the range of 5-80% and 30-90%, respectively (Zweigelt 47% and 90%, respectively). The corresponding GSE (20 mg/ml) inhibited the coronary constrictions to histamine in the range of 40% to 80% (Zweigelt 80%). Additionally, all DAW antagonized the contractile responses to the thromboxane-mimetic U46619 and the isoprostane 8-iso-PGF2alpha, indicating a nonspecific inhibition. To characterize the vasoactive component(s), the Traminer GSE was separated representatively using ultrafiltration, solid phase extraction (SPE) on Isolute C18(EC), and Isolute SCX-2, as well as column chromatography (CC) on polyamide. The resulting fractions were subsequently bioassayed for vasorelaxing activity. Preliminary results refer to a very hydrophilic, nonpolyphenolic basic compound with a MW<1000 Da. Our findings demonstrate that certain Styrian wines have remarkable antagonistic effects on several endogenous agonists in vitro, and that also nonpolyphenolic components in grapes may contribute to cardiovascular protection. Further separation steps as well as phytochemical and pharmacological investigations are in progress.

Abstract
OBJECTIVE The aim of the present study was to analyse the relation between age and both dietary habits and leisure-time physical activity, and to determine nutrient inadequacy of aged groups in our population. DESIGN Cross-sectional study. SETTING A random sample of the 25-74-y-old population of Gerona, Spain. SUBJECTS A total of 838 men and 910 women were selected from among the general population according to the 1991 census. OUTCOME MEASURES Analysis of dietary habits, including amount and type of alcohol consumption, and detailed evaluation of leisure-time physical activity. RESULTS Nutrient densities of carbohydrates, vitamin B(1), vitamin B(12), vitamin C, vitamin E, folate, potassium, iron, magnesium, copper, and dietary fiber increased significantly (P<0.05) with age in both genders, whereas an inverse trend was observed for total fat, saturated fatty acids, cholesterol, and sodium. Multiple linear regression analysis revealed a direct association of healthy dietary habits, characterized through a composite dietary score, with age after adjusting for several confounders both in men and women (P<0.001). This score was composed of folate, vitamin C, vitamin E, beta-carotene, dietary fibre, cholesterol, saturated fatty acids, and sodium. In all, 29 and 10% of male and female subjects aged 65-74 y, respectively, reported inadequate intakes of six or more of 16 nutrients. Total leisure-time physical activity increased with age in men (P<0.002), and was not different among female age groups. CONCLUSION Dietary behaviours and levels of physical activity spent during leisure time indicate a healthy lifestyle of the aged men and women in the present population. Nutrient inadequacy observed in some aged men and women, however, deserves particular intervention of health-care programmes for this growing part of our society.

Abstract
To clarify the effects of alcohol consumption on hepatocellular injury, we examined aspartate and alanine aminotransferases (AST and ALT), and gamma-glutamyltransferase (GGT), together with weekly alcohol consumption calculated from a self-rating questionnaire, in 1113 Japanese salesmen. The thresholds of associations between alcohol consumption and liver markers were estimated by the benchmark dose (BMD) method. The AST, ALT and GGT were positively correlated with alcohol intake (p<0.001), as well as age and body mass index (BMI); the relations to alcohol were statistically significant even when controlling for age, BMI and smoking habit. Although the AST and GGT were associated with four types of alcoholic beverage (p<0.01), it was only whiskey that had close relation to the ALT (p<0.05). The thresholds of alcohol consumption (ethanol g/week), i.e., 95% lower confidence limits of the BMD, were 362 for AST, 660 for ALT, and 252 for GGT. The thresholds for GGT and AST in Japanese men seem to be somewhat higher than those reported in Western countries. It is suggested that hepatocellular injury (i.e., AST elevation) in Japanese men may emerge at the ethanol level of more than 50 g/day.
