The power of Dionysus-Effects of red wine on consciousness in a naturalistic setting. PLoS One 2021; 16:e0256198.

Abstract
There is lack of research on effects of red wine on consciousness when drank in wine bars designed to enhance the pleasurableness of the wine drinking experience. Effects of a moderate dose of red wine (≈ 40.98 g of ethanol) on consciousness were examined in a naturalistic study taking place in a wine bar located in one of the most touristic areas of Lisbon, Portugal. One hundred two participants drank in one of three conditions: alone, in dyad, or in groups up to six people. Red wine increased pleasure and arousal, decreased the awareness of time, slowed the subjective passage of time, increased the attentional focus on the present moment, decreased body awareness, slowed thought speed, turned imagination more vivid, and made the environment become more fascinating. Red wine increased insightfulness and originality of thoughts, increased sensations of oneness with the environment, spiritual feelings, all-encompassing love, and profound peace. All changes in consciousness occurred regardless of volunteers drinking alone, in dyad or in group. Men and women did not report different changes in consciousness. Older age correlated with greater increases in pleasure. Younger age correlated with greater increases in fascination with the environment of the wine bar. Drinking wine in a contemporaneous Western environment designed to enhance the pleasurableness of the wine drinking experience may trigger changes in consciousness commonly associated with mystical-type states.

Abstract
On-the-go beverages that may deliver health, increase stamina, reduce stress and provide longevity have captivated consumers and catapulted the food industry into the era of functional food and beverages. The industry initially responded with rapid growth. However, with time product diversification has become somewhat compromised, since most products contain the same bioactive components. Advancement in product technology has to be backed with research. Mere fortification of tea, juices and water, without any scientific evaluation of their functionality, has to be discouraged. Fruits and vegetable juices are excellent matrices for delivery of physiologically active component. Science backed designing will get us closer to tailoring fruits and vegetable juices into 'smart' beverages. As a case study two fruit-based products, probiotic and fruit wines (non-grape) have been considered here. This review explores the possibility of what more may be done to take the fruit and vegetable beverages to next step.

Abstract
BACKGROUND The devastating effects of heavy alcohol drinking have been long time recognized. In the last decades, potential benefits of modest red wine drinking were suggested. In European countries in which red wide intake is not negligible (such as France), the association between cholesterol and cardiovascular (CV) risk was less evident, suggesting the action of some protective molecules in red wine or other foods and drinks. METHODS This narrative review is based on the material searched for and obtained via PubMed up to May 2016. The search terms we used were: "red wine, cardiovascular, alcohol" in combination with "polyphenols, heart failure, infarction". RESULTS Epidemiological and mechanistic evidence of a J-shaped relationship between red wine intake and CV risk further supported the "French paradox". Specific components of red wine both in vitro and in animal models were discovered. Polyphenols and especially resveratrol largely contribute to CV prevention mainly through antioxidant properties. They exert beneficial effects on endothelial dysfunction and hypertension, dyslipidemia, metabolic diseases, thus reducing the risk of adverse CV events such as myocardial infarction ischemic stroke and heart failure. Of interest, recent studies pointed out the role of ethanol itself as a potential cardioprotective agent, but a clear epidemiological evidence is still missing. The aim of this narrative review is to update current knowledge on the intracellular mechanism underlying the cardioprotective effects of polyphenols and ethanol. Furthermore, we summarized the results of epidemiological studies, emphasizing their methodological criticisms and the need for randomized clinical trials able to clarify the potential role of red wine consumption in reducing CV risk. CONCLUSION Caution in avowing underestimation of the global burden of alcohol-related diseases was particularly used.

Abstract
Excessive drinking of alcohol is becoming a worldwide problem, and people have recognized that there exists a close relationship between chronic kidney disease (CKD) and alcohol consumption. However, there are many inconsistencies between experimental and clinical studies on alcohol consumption and kidney damage. The possible reason for this contradictory conclusion is the complex drinking pattern of humans and some bioactivators in wine. In addition, the design itself of the clinical studies can also produce conflicting interpretations of the results. Considering the benefits of light-to-moderate alcohol consumption, we recommend that CKD patients continue light-to-moderate drinking, which is beneficial to them. Because alcohol consumption can lead to adverse events, we do not advise non-drinkers to start to drink. Although light-to-moderate alcohol consumption may not pose a risk to patients with CKD, the patients’ condition needs to be considered. Consumption of even small amounts of alcohol can be associated with increased death risk. Additional clinical and experimental studies are needed to clarify the effect of alcohol on the kidneys and alcohol consumption on CKD patients.

Abstract
Several epidemiological studies associated the consumption of wine with the reduction of the risk factors for cardiovascular disease and certain cancers, as well as for diabetes. These conditions are characterized by inflammatory mechanisms in addition to other biological mechanisms. Acute and chronic inflammation is mediated by a plethora of biomarkers production and pathway activation. Since the health promoting properties of wine in different pathological conditions may include the reduction of inflammation, the aim of this paper was to collect and review the in vitro, in vivo, and human studies performed to evaluate the effects of wine on different models of inflammation. Although great variability in wine intake, period of consumption, and content of phenolic compounds was observed, data from both human and animal studies showed a positive modulation of inflammatory biomarkers (cytokines, coagulation parameters) and oxidative stress (mainly malondialdehyde) involved in cardiovascular function. In addition, some convincing evidence was obtained in different models suggesting a positive modulation of risk factors for gastric and intestinal inflammation. Contradictory results were obtained for metabolic syndrome and type 2 diabetes. To date, no significant paper has been published in the area of immune function. Integrating in vivo data and in vitro studies, the NF-κB pathway has been identified as a critical target for the protective properties of a moderate wine consumption.

Abstract
High occurrence of obesity currently constitutes the main nutritional disease of the canine species. There is evidence that leptin increases during obesity in dogs. Hyperleptinemia is associated with increased neutrophil oxidative metabolism in obese humans and contributes to oxidative stress. However, in obese dogs, the probable relationship between this condition and the activation of the oxidative metabolism of neutrophils has yet to be established. Thus, we investigated the hypothesis that neutrophil activation and systemic oxidative stress occur in dogs with hyperleptinemia. A control group of 24 healthy dogs with a body condition score (BCS) of 4-5, an overweight group of 25 dogs with a BCS of 6-7, and 27 obese dogs with a BCS of 8-9, were composed. Two subgroups were formed composed of dogs with and without hyperleptinemia, grouped according to the 95% confidence interval obtained for plasma leptin values of the control group. Changes in obesity markers (body condition score, adiponectin and plasma leptin) and plasma oxidative stress (lipid peroxidation, total antioxidant and oxidant capacities and oxidative stress index) were measured in all the dogs selected. Neutrophil oxidative metabolism was evaluated in flow cytometry by superoxide production with the probe hydroethidine and by hydrogen peroxide production with the probe 2',7'-dichlorofluorescein diacetate, with or without phorbol myristate acetate (PMA) stimulation. Apoptosis and neutrophil viability were quantified in a capillary flow cytometer using Annexin VPE, with or without camptothecin apoptosis inducing effect. Obese dogs presented higher systemic oxidative stress, hyperleptinemia and preactivated neutrophils with accelerated apoptosis. Dogs with hyperleptinemia and obese dogs presented higher neutrophil superoxide production under PMA stimulation and the presence of systemic oxidative stress compared with control. To our knowledge, this is probably the first evidence that preactivation of the oxidative metabolism of circulating neutrophils occurs in dogs with hyperleptinemia, a condition that can induce systemic oxidative stress in the canine species.

Abstract
Ultrahigh-performance liquid chromatography-quadrupole/time-of-flight mass spectrometry (UPLC-QTOF/MS) was developed for rapid and sensitive analysis of the effect of rice wine on the metabolites of the main components of herbal medicine in rat urine. Using Cornus officinalis as a model of herbal medicine, the metabolite profiles of crude and processed (steaming the crude drug presteeped in rice wine) Cornus officinalis extracts in rat urine were investigated. The metabolites of Cornus officinalis were identified by using dynamic adjustment of the fragmentor voltage to produce structure-relevant fragment ions. In this work, we identified the parent compounds and metabolites of crude and processed Cornus officinalis in rats. In total, three parent compounds and seventeen new metabolites of Cornus officinalis were found in rats. The contents of the parent compounds and metabolites in vivo varied significantly after intragastric (i.g.) administration of aqueous extracts of crude and processed Cornus officinalis. Data from this study suggests that UPLC-QTOF/MS could be used as a potential tool for uncovering the effects of excipients found in the metabolites of the main components of herbal medicine, in vivo, to predict and discover the processing mechanisms of herbal medicine.

Abstract
AIMS To evaluate the effect of acute and chronic consumption of red wine or de-alcoholized red wine with a similar antioxidant capacity on plasma total antioxidant capacity (TEAC), nuclear factor-κB (NF-κB) activity and F2-isoprostanes (8-iso-PGF(2α)) in healthy men. METHODS Nineteen healthy men with an increased waist circumference (≥94 cm) and a body mass index above 25 kg/m(2) participated in a randomized, controlled crossover design trial. They daily consumed 450 ml of red wine (four drinks; 41.4 g alcohol) or 450 ml of de-alcoholized red wine during dinner for 4 weeks each. On the last day of each treatment period, blood was collected before and 1 h after a standardized dinner with red wine or de-alcoholized red wine and also 24-h urine was collected. RESULTS Absolute TEAC levels were higher 1 h after dinner with red wine compared with dinner with de-alcoholized red wine (1.3 versus 1.1 mmol Trolox equivalents/l; P = 0.03). Consumption of dinner together with de-alcoholized red wine acutely stimulated NF-κB activity in peripheral blood mononuclear cells (0.4-0.7 HeLa equivalents/2.5 μg protein; P = 0.006), whereas this increase was completely suppressed when the dinner was combined with red wine. A chronic increase in urinary 8-iso-PGF(2α) after 4 weeks of red wine consumption compared with de-alcoholized red wine consumption (157 pg/mg creatinine and 141 pg/mg creatinine, respectively, P = 0.006) was also observed. CONCLUSIONS Consumption of a moderate dose of red wine can acutely increase plasma TEAC and suppress NF-κB activation induced by a meal. Controversially, 4 weeks of red wine consumption compared with de-alcoholized red wine consumption increases the oxidative lipid damage marker 8-iso-PGF(2α).

Abstract
Wine micro-oxygenation is a globally used treatment and its effects were studied here by analysing by untargeted LC-MS the wine metabolomic fingerprint. Eight different procedural variations, marked by the addition of oxygen (four levels) and iron (two levels) were applied to Sangiovese wine, before and after malolactic fermentation. Data analysis using supervised and unsupervised multivariate methods highlighted some known candidate biomarkers, together with a number of metabolites which had never previously been considered as possible biomarkers for wine micro-oxygenation. Various pigments and tannins were identified among the known candidate biomarkers. Additional new information was obtained suggesting a correlation between oxygen doses and metal contents and changes in the concentration of primary metabolites such as arginine, proline, tryptophan and raffinose, and secondary metabolites such as succinic acid and xanthine. Based on these findings, new hypotheses regarding the formation and reactivity of wine pigment during micro-oxygenation have been proposed. This experiment highlights the feasibility of using unbiased, untargeted metabolomic fingerprinting to improve our understanding of wine chemistry.

Intake of alcohol-free red wine modulates antioxidant enzyme activities in a human intervention study. Pharmacol Res 2012; 65:609-14.

Abstract
Wine intake affects the antioxidant enzyme activities that contribute to the overall antioxidant properties of wine. The purpose of this study is to evaluate whether alcohol-free wine has any effect on antioxidant enzymes. The study was a randomized cross-over human intervention. A low phenolic diet (LPD) was designed to prevent interference from polyphenols in other food sources. In the first period, the volunteers ate only this low phenolic diet; in the second, they ate this diet and also drank 300 mL of alcohol-free wine. The enzymes under study were: superoxide dismutase, catalase, glutathione peroxidase and glutathione reductase. The activities of glutathione reductase, superoxide dismutase and catalase decreased during the LPD period and increased in the LPD+dealcoholized wine period. On the third day of intervention, significant changes were observed in glutathione reductase and superoxide dismutase activity for both intervention periods under study. Catalase activity changed significantly on the seventh day of intervention. Antioxidant enzymes modulated their activity more easily than the endogenous antioxidants, which did not undergo any changes. Our results show for the first time that the increase in the activity of the antioxidant enzymes is not due to the alcohol content in wine but to the polyphenolic composition. Therefore, alcohol-free wine could be an excellent source of antioxidants to protect people suffering from oxidative stress (cancer, diabetes, alzheimer, etc.) who should not consume alcohol.

Abstract
OBJECTIVE We determined and compared acute effects of different alcoholic beverages on oxygen-induced increase in oxidative stress plasma marker and arterial stiffness in healthy humans. METHODS Ten males randomly consumed one of four tested beverages: red wine (RW), vodka, beer (0.32 g ethanol/kg body wt) and water as control. Every beverage was consumed once, a week apart, in a cross-over design. The volunteers breathed 100% normobaric O(2) between 60th and 90th min of 3h study protocol. Plasma lipid peroxides (LOOH) and uric acid (UA) concentration, blood alcohol concentration (BAC) and arterial stiffness (indicated by augmentation index, AIx) were measured before and 30, 60, 90, 120 and 180 min after beverage consumption. RESULTS Intake of all alcoholic beverages caused a similar increase of BAC. The oxygen-induced elevation in AIx was similarly reduced in all three groups relative to the control (3.4 ± 1.3%, 5.4 ± 2.2% and 0.2 ± 1.6% vs. 13.7 ± 2.6% for red wine, vodka, beer and control, respectively, 60 min after intake). Exposure to oxygen resulted in increased plasma LOOH in all groups. However, in RW group this increase was lowest (1.1 ± 0.5) in comparison to the vodka (2.1 ± 0.5), beer (1.6±0.3) and control (2.5 ± 0.4μM/L H(2)O(2)). 60 min after intake of RW and beer plasma UA significantly increased (34 ± 4 and 15 ± 3) in contrast to vodka and control (-6 ± 2 and -8 ± 2μmol/L). CONCLUSION All three alcoholic beverages provided similar protection against oxygen-induced increase in arterial stiffness, probably due to central vasodilatatory effect of alcohol itself, but only RW provided protection against oxygen-induced oxidative stress.

Abstract
Numerous studies indicate that moderate red wine consumption is associated with a protective effect against all-cause mortality. Since oxidative stress constitutes a unifying mechanism of injury of many types of disease processes, it should be expected that polyphenolic antioxidants account for this beneficial effect. Nevertheless, beyond the well-known antioxidant properties of these compounds, they may exert several other protective mechanisms. Indeed, the overall protective effect of polyphenols is due to their large array of biological actions, such as free radical-scavenging, metal chelation, enzyme modulation, cell signalling pathways modulation and gene expression effects, among others. Wine possesses a variety of polyphenols, being resveratrol its most outstanding representative, due to its pleiotropic biological properties. The presence of ethanol in wine aids to polyphenol absorption, thereby contributing to their bioavailability. Before absorption, polyphenols must be hydrolyzed by intestinal enzymes or by colonic microflora. Then, they undergo intestinal and liver metabolism. There have been no reported polyphenol adverse effects derived from intakes currently associated with the normal diet. However, supplements for health-protection should be cautiously used as no level definition has been given to make sure the dose is safe. The role of oxidative stress and the beneficial effects of wine polyphenols against cardiovascular, cancer, diabetes, microbial, inflammatory, neurodegenerative and kidney diseases and ageing are reviewed. Future large scale randomized clinical trials should be conducted to fully establish the therapeutic use of each individual wine polyphenol against human disease.
