Valorization of Cashew Apple Waste into a Low-Alcohol, Healthy Drink Using a Co-Culture of Cyberlindnera rhodanensis DK and Lactobacillus pentosus A14-6. Foods 2024; 13:1469. [PMID: 38790769 PMCID: PMC11120566 DOI: 10.3390/foods13101469] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/16/2024] [Revised: 05/07/2024] [Accepted: 05/08/2024] [Indexed: 05/26/2024] Open
Abstract
This study investigated the potential of microbial fermentative transforming processes in valorizing the cashew apple by-product into a low-alcohol, health-benefiting beverage. We particularly investigated the use of a non-Saccharomyces yeast, Cyberlindnera rhodanensis DK, as the main targeted microbe. At 30 °C without agitation, C. rhodanensis DK caused changes in key parameters during the fermentation of cashew apple juice (CAJ) in terms of varied pH values and initial sugar concentrations. This result indicated that pure CAJ, with pH adjusted to 6 and with the original 6.85% (w/v) total sugar content, was the most feasible condition, as glucose and fructose were mostly consumed at 12 days of fermentation. A co-culture approach with either Saccharomyces cerevisiae TISTR 5088 or Lactobacillus pentosus A14-6 was investigated to improve both physicochemical and fermentation characteristics. Co-fermentation with S. cerevisiae TISTR 5088 resulted in significantly increased ethanol accumulation to 33.61 ± 0.11 g/L, but diminished bioactive compounds, antioxidant activity, and antidiabetic potential. In contrast, co-fermentation with L. pentosus A14-6 demonstrated excellent outcomes, as it significantly increased sugar consumption and finally remained at only 4.95 g/L compared to C. rhodanensis DK alone, produced lower levels of ethanol at only 19.47 ± 0.06 g/L, and higher total titratable acid (TTA), resulting in a final pH of 3.6. In addition, co-fermentation with this lactic acid bacterium significantly enhanced bioactive compounds and antioxidant activity and also retained potential antidiabetic properties. These findings highlight the feasibility of using tailored microbial fermentation strategies to produce low-alcohol beverages with enhanced health-promoting properties from CAJ; however, product-development processes following health food regulations and sensory evaluation are necessary.

Assessment of Tannin Tolerant Non- Saccharomyces Yeasts Isolated from Miang for Production of Health-Targeted Beverage Using Miang Processing Byproducts. J Fungi (Basel) 2023; 9:jof9020165. [PMID: 36836280 PMCID: PMC9964396 DOI: 10.3390/jof9020165] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/21/2022] [Revised: 01/18/2023] [Accepted: 01/20/2023] [Indexed: 01/28/2023] Open
Abstract
This research demonstrated an excellent potential approach for utilizing Miang fermentation broth (MF-broth), a liquid residual byproduct from the Miang fermentation process as a health-targeted beverage. One hundred and twenty yeast strains isolated from Miang samples were screened for their potential to ferment MF-broth and four isolates, P2, P3, P7 and P9 were selected, based on the characteristics of low alcoholic production, probiotic properties, and tannin tolerance. Based on a D1/D2 rDNA sequence analysis, P2 and P7 were identified to be Wikerhamomyces anomalus, while P3 and P9 were Cyberlindnera rhodanensis. Based on the production of unique volatile organic compounds (VOCs), W. anomalus P2 and C. rhodanensis P3 were selected for evaluation of MF-broth fermentation via the single culture fermentation (SF) and co-fermentation (CF) in combination with Saccharomyces cerevisiae TISTR 5088. All selected yeasts showed a capability for growth with 6 to 7 log CFU/mL and the average pH value range of 3.91-4.09. The ethanol content of the fermented MF-broth ranged between 11.56 ± 0.00 and 24.91 ± 0.01 g/L after 120 h fermentation, which is categorized as a low alcoholic beverage. Acetic, citric, glucuronic, lactic, succinic, oxalic and gallic acids slightly increased from initial levels in MF-broth, whereas the bioactive compounds and antioxidant activity were retained. The fermented MF-broth showed distinct VOCs profiles between the yeast groups. High titer of isoamyl alcohol was found in all treatments fermented with S. cerevisiae TISTR 5088 and W. anomalus P2. Meanwhile, C. rhodanensis P3 fermented products showed a higher quantity of ester groups, ethyl acetate and isoamyl acetate in both SF and CF. The results of this study confirmed the high possibilities of utilizing MF-broth residual byproduct in for development of health-targeted beverages using the selected non-Saccharomyces yeast.

Advanced Glycation End Products Are Associated with Diabetes Status and Physical Functions in Patients with Cardiovascular Disease. Nutrients 2022; 14:nu14153032. [PMID: 35893886 PMCID: PMC9330730 DOI: 10.3390/nu14153032] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/06/2022] [Revised: 07/19/2022] [Accepted: 07/22/2022] [Indexed: 01/27/2023] Open
Abstract
Advanced glycated end products (AGEs) accumulate systemically and cause diabetes complications. However, whether noninvasive measurable AGEs are associated with diabetes status and physical functions remains unclear. One hundred and ten patients with cardiovascular disease (CVD) who underwent outpatient cardiac rehabilitation were included. AGEs scores, using AGEs sensors, were evaluated concomitantly with a physical evaluation, including testing the isometric knee extension strength (IKES) and 6 min walking distance (6MWD). Thirty-three (30%) patients had a history of diabetes mellitus (DM). The AGEs score was not different in the presence of DM history (0.52 ± 0.09 vs. 0.51 ± 0.09, p = 0.768) and was not correlated with blood glucose (r = 0.001, p = 0.995). The AGEs score was positively correlated with hemoglobin A1c (HbA1c, r = 0.288, p = 0.004) and negatively correlated with physical functions (IKES, r = −0.243, p = 0.011; 6MWD, r = −0.298, p = 0.002). The multivariate analysis demonstrated that 6MWD was independently associated with a high AGEs score (>0.52). The AGEs score was associated with HbA1c, IKES, and 6MWD in patients with CVD. The AGEs score might be a useful indicator for evaluating not only glycemic control but also physical functions.

Abstract
At-risk alcohol use is a significant risk factor associated with multisystemic pathophysiological effects leading to multiorgan injury and contributing to 5.3% of all deaths worldwide. The alcohol-mediated cellular and molecular alterations are particularly salient in vulnerable populations, such as people living with HIV (PLWH), diminishing their physiological reserve, and accelerating the aging process. This review presents salient alcohol-associated mechanisms involved in exacerbation of cardiometabolic and neuropathological comorbidities and their implications in the context of HIV disease. The review integrates consideration of environmental factors, such as consumption of a Western diet and its interactions with alcohol-induced metabolic and neurocognitive dyshomeostasis. Major alcohol-mediated mechanisms that contribute to cardiometabolic comorbidity include impaired substrate utilization and storage, endothelial dysfunction, dysregulation of the renin-angiotensin-aldosterone system, and hypertension. Neuroinflammation and loss of neurotrophic support in vulnerable brain regions significantly contribute to alcohol-associated development of neurological deficits and alcohol use disorder risk. Collectively, evidence suggests that at-risk alcohol use exacerbates cardiometabolic and neurocognitive pathologies and accelerates biological aging leading to the development of geriatric comorbidities manifested as frailty in PLWH.

Abstract
AIMS The aim of this study is to determine the relationship between alcohol consumption and atrial fibrillation (AF)-related adverse events in the AF population. METHODS AND RESULTS A total of 9411 patients with nonvalvular AF in a prospective observational registry were categorized into four groups according to the amount of alcohol consumption-abstainer-rare, light (<100 g/week), moderate (100-200 g/week), and heavy (≥200 g/week). Data on adverse events (ischaemic stroke, transient ischaemic attack, systemic embolic event, or AF hospitalization including for AF rate or rhythm control and heart failure management) were collected for 17.4 ± 7.3 months. A Cox proportional hazard models was performed to calculate hazard ratios (HRs), and propensity score matching was conducted to validate the results. The heavy alcohol consumption group showed an increased risk of composite adverse outcomes [adjusted hazard ratio (aHR) 1.32, 95% confidence interval (CI) 1.06-1.66] compared with the reference group (abstainer-rare group). However, no significant increased risk for adverse outcomes was observed in the light (aHR 0.88, 95% CI 0.68-1.13) and moderate (aHR 0.91, 95% CI 0.63-1.33) groups. In subgroup analyses, adverse effect of heavy alcohol consumption was significant, especially among patients with low CHA2DS2-VASc score, without hypertension, and in whom β-blocker were not prescribed. CONCLUSION Our findings suggest that heavy alcohol consumption increases the risk of adverse events in patients with AF, whereas light or moderate alcohol consumption does not.

Alcoholic beverage consumption, changes in blood pressure, and incidence of hypertension in the Longitudinal Adult Health Study (ELSA-Brasil). Nutrition 2021; 91-92:111387. [PMID: 34303960 DOI: 10.1016/j.nut.2021.111387] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/11/2020] [Revised: 05/11/2021] [Accepted: 05/31/2021] [Indexed: 11/17/2022]
Abstract
OBJECTIVES Alcohol consumption is generally associated with increased risk of hypertension. We aimed to investigate, prospectively, the effect of alcoholic-beverage consumption on blood pressure (BP) and incidence of hypertension, after a 4-y follow-up, in participants of the Longitudinal Adult Health Study (ELSA-Brasil). METHODS We analyzed information from 3,990 participants (ages 35-74 y), men and women, from educational and research institutions, at baseline (2008-2010) and follow-up (2012-2014). Socioeconomic, hemodynamic, anthropometric, and health data were collected. Hypertension was defined as systolic BP ≥ 140 mm Hg and/or diastolic BP ≥ 90 mm Hg and/or use of antihypertensive medication. Change in alcohol consumption (g/d) was estimated by subtracting total consumed at follow-up from total consumed at baseline, and was categorized in tertiles. RESULTS The consumption of alcoholic beverages was associated with changes in BP and hypertension only in men. Individuals who reduced total consumption of alcohol showed a smaller increase in systolic BP (1.1 versus 2.3 mm Hg; P = 0.03) and diastolic BP (1.3 versus 2.2 mm Hg; P = 0.008) compared to individuals who increased consumption. In addition, individuals in the highest tertiles of total consumption of alcohol (odds ratio [OR], 1.62; 95% confidence interval [CI], 1.14-2.29) and consumption of beer (OR, 1.51; 95% CI, 1.07-12.13), wine (OR, 1.71; 95% CI, 1.01-2.86), and spirits (OR, 2.01; 95% CI, 1.21-3.32) showed higher odds ratios for hypertension compared to the lowest tertile. CONCLUSIONS Increased consumption of alcoholic beverages was positively associated with increased BP levels and higher chances of developing hypertension in men.

Alcohol consumption in relation to carotid subclinical atherosclerosis and its progression: results from a European longitudinal multicentre study. Eur J Nutr 2021; 60:123-134. [PMID: 32206896 PMCID: PMC7867553 DOI: 10.1007/s00394-020-02220-5] [Citation(s) in RCA: 13] [Impact Index Per Article: 3.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/27/2019] [Accepted: 03/04/2020] [Indexed: 12/31/2022]
Abstract
BACKGROUND/AIM The association between alcohol consumption and subclinical atherosclerosis is still unclear. Using data from a European multicentre study, we assess subclinical atherosclerosis and its 30-month progression by carotid intima-media thickness (C-IMT) measurements, and correlate this information with self-reported data on alcohol consumption. METHODS Between 2002-2004, 1772 men and 1931 women aged 54-79 years with at least three risk factors for cardiovascular disease (CVD) were recruited in Italy, France, Netherlands, Sweden, and Finland. Self-reported alcohol consumption, assessed at baseline, was categorized as follows: none (0 g/d), very-low (0 - 5 g/d), low (> 5 to ≤ 10 g/d), moderate (> 10 to ≤ 20 g/d for women, > 10 to ≤ 30 g/d for men) and high (> 20 g/d for women, > 30 g/d for men). C-IMT was measured in millimeters at baseline and after 30 months. Measurements consisted of the mean and maximum values of the common carotids (CC), internal carotid artery (ICA), and bifurcations (Bif) and whole carotid tree. We used quantile regression to describe the associations between C-IMT measures and alcohol consumption categories, adjusting for sex, age, physical activity, education, smoking, diet, and latitude. RESULTS Adjusted differences between median C-IMT values in different levels of alcohol consumption (vs. very-low) showed that moderate alcohol consumption was associated with lower C-IMTmax[- 0.17(95%CI - 0.32; - 0.02)], and Bif-IMTmean[- 0.07(95%CI - 0.13; - 0.01)] at baseline and decreasing C-IMTmean[- 0.006 (95%CI - 0.011; - 0.000)], Bif-IMTmean[- 0.016(95%CI - 0.027; - 0.005)], ICA-IMTmean[- 0.009(95% - 0.016; - 0.002)] and ICA-IMTmax[- 0.016(95%: - 0.032; - 0.000)] after 30 months. There was no evidence of departure from linearity in the association between alcohol consumption and C-IMT. CONCLUSION In this European population at high risk of CVD, findings show an inverse relation between moderate alcohol consumption and carotid subclinical atherosclerosis and its 30-month progression, independently of several potential confounders.

The effect of ALDH2 rs671 gene mutation on clustering of cardiovascular risk factors in a big data study of Chinese population: associations differ between the sexes. BMC Cardiovasc Disord 2020; 20:509. [PMID: 33276716 PMCID: PMC7716427 DOI: 10.1186/s12872-020-01787-5] [Citation(s) in RCA: 8] [Impact Index Per Article: 1.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/01/2020] [Accepted: 11/18/2020] [Indexed: 11/10/2022] Open
Abstract
BACKGROUND The ALDH2 rs671 genetic polymorphism has been linked with cardiovascular diseases (CVDs), but comprehensive epidemiological studies are lacking. An observational, retrospective big data study was carried out to evaluate the associations between this polymorphism and clustering cardiovascular risk factors (CRFs) in a Chinese population. METHODS A total of 13,101 individuals (8431 males and 4670 females) were enrolled. Genetic polymorphism was assessed using gene mutation detection kits, coupled with an automatic fluorescent analyzer. Other data were obtained from the records of the Department of Health Care at Peking Union Medical College Hospital. RESULTS Comparing the concentrations of common biochemical analytes, including BMI, SBP, DBP, ALT, AST, γ-GT, TBil, Cr, Glu, TC, TG, and HDL-C among individuals with the GG, GA, and AA genotypes of ALDH2 rs671, we found significant differences in males (all p < 0.001), but not in females. For males, the frequencies of hypertension, diabetes, and obesity were significantly higher for GG than for GA or AA (all p < 0.05). However, there was no significant difference for dyslipidemia, and no significant associations were observed for all frequencies in females. The prevalence of individuals with 1-4 CRFs was significantly higher among GG males than those carrying GA or AA, and fewer GG males had non-CRFs (all p < 0.05). CONCLUSION Polymorphisms of ALDH2 rs671 are associated with clustering CRFs, especially hypertension and diabetes in males, but not in females. These associations are likely mediated by alcohol intake, which is also associated with this gene.

Geng TT, Jafar TH, Yuan JM, Koh WP. The impact of diabetes on the association between alcohol intake and the risk of end-stage kidney disease in the Singapore Chinese Health Study. J Diabetes 2020; 12:583-593. [PMID: 32142209 DOI: 10.1111/1753-0407.13034] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.4] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/07/2019] [Revised: 01/31/2020] [Accepted: 03/04/2020] [Indexed: 11/29/2022] Open
Abstract
BACKGROUND The relationship between alcohol intake and end-stage kidney disease (ESKD) risk is controversial. Moreover, while evidence has shown that the relationship between alcohol and atherosclerosis may be modified by diabetes, whether this applies to ESKD is unknown. METHODS We examined these associations in the Singapore Chinese Health Study, a prospective cohort of 63 257 adults aged 45 to 74 years. Information on alcohol intake, diet, lifestyle factors, and medical history was collected at recruitment. We identified 1217 ESKD cases via linkage with the Singapore Renal Registry after a mean follow-up of 17.5 years. Cox regression models were used to estimate hazard ratios (HRs) and 95% CI of ESKD. RESULTS Among the participants without diabetes at baseline, monthly to weekly drinking was associated with a decreased risk of ESKD (HR 0.69; 95% CI, 0.54-0.87) compared to nondrinkers. In contrast, this association was attenuated and not significant among those with diabetes (HR 0.82; 95% CI, 0.58-1.16; Pinteraction = .19). Comparatively, alcohol intake of ≥2 drinks per day was significantly associated with an increased risk of ESKD compared to nondrinkers among those with diabetes (HR 2.00; 95% CI, 1.14-3.53) but not among those without diabetes (HR 0.91; 95% CI, 0.53-1.56; Pinteraction = .01). The risk of ESKD among those with diabetes and who also consumed ≥2 drinks per day was increased by nearly 12-fold compared to nondrinkers without diabetes (HR 11.6; 95% CI, 6.73-19.9). CONCLUSION Low-dose drinking is associated with a reduced risk of ESKD among individuals without diabetes. However, joint exposure to heavy drinking and diabetes is associated with a substantially higher risk of ESKD.

Abstract
AIM β-actin (ACTB) participates in the vascular remodeling and contributes to the cardiovascular diseases. Herein, we investigated the associations of ACTB with hypertension and stroke. METHODS Three single-nucleotide polymorphisms in ACTB were selected for genotyping in 2,012 hypertension cases and 2,210 controls. The associations of ACTB with hypertension and stroke were examined in another follow-up study. Logistic and Cox regression were performed in a case-control study and a follow-up study, respectively. Additive scale interaction was examined by calculating the relative excess risk due to interaction (RERI), attributable proportion due to interaction (AP) and synergy index (SI). The multiplicative interaction hazard ratio was calculated by fitting the Cox regression model. ACTB mRNA in peripheral blood mononuclear cells was measured in ischemic stroke (IS) cases and in controls. RESULTS The associations of rs852426 with hypertension and stroke had statistical significance in drinkers but not after Bonferroni correction. An additive interaction of rs852426 and drinking was observed for stroke incidence, the adjusted RERI was -0.907 (p=4.108×10-4), and the multiplicative interaction was still sound (HR=0.541, p=0.048). Furthermore, the significant interaction was further replicated in a nested case-control study. In the drinking population, the relative expression of ACTB mRNA in IS was lower (0.99±0.26) than that in controls (1.13±0.20), with a p value of 0.026. CONCLUSIONS ACTB rs852426 was significantly associated with alcohol consumption on stroke risk, and the expression of ACTB mRNA in IS who had a drinking habit was significantly down-regulated. This finding will provide a novel insight into the prevention of stroke.

Effects of Moderate Ethanol Consumption on Lipid Metabolism and Inflammation Through Regulation of Gene Expression in Rats. Alcohol Alcohol 2019; 54:5-12.

Abstract
Aims Epidemiological studies and experimental data from rodent models have reported a non-linear relationship between consumption of alcohol and cardiovascular disease (CVD) risk that suggests that light-to-moderate drinking as opposed to excessive consumption may provide some cardiovascular benefits. The present study examined potential mechanisms by which moderate alcohol consumption may provide a protective effect against CVD. Short summary Wistar rats exposed for 3 months to a 20% ethanol intermittent-access voluntary drinking paradigm displayed a reduction in epididymal fat, blood glucose and non-HDL and total cholesterol. These effects were accompanied by decreased expression of Hmgcr, Srebp-2, Cox-2 and RelA, indicating downregulation of genes involved in cholesterol synthesis and inflammation. Methods Twenty-four male Wistar rats voluntarily consumed a 20% v/v ethanol solution on alternate days for 13 weeks (ethanol-treated) or were given access to water alone (non-ethanol-exposed control). Results There was no difference in body weight gain between the two groups, however, epididymal fat weight was lower in ethanol-fed rats (P = 0.030). Blood glucose, total cholesterol, non-high-density lipoprotein (HDL) and oxidized low-density lipoprotein (LDL) levels were lower in the ethanol group compared to controls (P < 0.05). There was a significant reduction in the expression of hydroxymethylglutaryl-coenzyme A reductase and sterol regulatory element-binding protein-2 in ethanol-treated rats (P < 0.05), suggesting that ethanol may have lowered cholesterol levels via downregulation of genes involved in cholesterol synthesis. Paraoxonase-1, which is associated with inhibition of LDL cholesterol oxidation, was upregulated in the ethanol group (P = 0.029). Ethanol-treated rats exhibited significantly lower levels of high-mobility box group protein 1 (P ≤ 0.05). Cyclooxygenase-2 and RelA gene expression were significantly lower in ethanol-treated rats (P < 0.05), indicating possible anti-inflammatory effects. Conclusions These findings suggest that moderate ethanol consumption may potentially contribute to improved cardiovascular outcomes by reducing body fat, improving blood cholesterol and blood glucose, and modulation of gene expression involved in inflammation and/or cholesterol synthesis.

Abstract
OBJECTIVE In this study, we aimed to investigate the antioxidant effects of selenium and coenzyme Q on renal damage in a partial unilateral ureteral obstruction (PUUO) in a rat model. MATERIAL AND METHODS A total of 24 Sprague-Dawley rats were divided into four groups as Group 1 Control Group, Group 2, PUUO Group, Group 3 PUUO + coenzyme Q group, Group 4 PUUO + selenium group. Paraoxonase (PON), total antioxidant capacity (TAC), and total oxidant levels (TOS) were analyzed biochemically from tissue and blood samples. Tissue samples were examined histopathologically. RESULTS The TAC in the tissues was found to be statistically significantly increased in Groups 3 and 4, compared to Group 2. Tissue TOS was found to be significantly reduced in Groups 3 and 4, compared to Group 2. Serum PON levels were significantly increased in Group 3 and 4, compared to Group 1 and 2. Histopathological examination showed that interstitial inflammation and congestion were lesser in the coenzyme Q and selenium groups than in the PUUO group. A more significant decrease was found in the selenium group than in the coenzyme Q group. CONCLUSION Our study results showed that coenzyme Q and selenium reduced the oxidation and the damage in tissue in PUUO in rats.

Abstract
Aim To evaluate protective immunosuppressive dose and time-dependent effects of ethanol in an in vitro model of acute inflammation in human Chang liver cells. Method The study was performed in 2016 and 2017 in the research laboratory of the Department of Trauma, Hand and Reconstructive Surgery, the University Hospital of the Goethe-University Frankfurt. Chang liver cells were stimulated with either interleukin (IL)-1β or IL-6 and subsequently treated with low-dose ethanol (85 mmol/L) or high-dose ethanol (170 mmol/L) for one hour (acute exposure) or 72 hours (subacute exposure). IL-6 and IL-1β release were determined by enzyme-linked immunosorbent assay. Neutrophil adhesion to Chang liver monolayers, production of reactive oxygen species, and apoptosis or necrosis were analyzed. Results Contrary to high-dose ethanol, acute low-dose ethanol exposure significantly reduced IL-1β-induced IL-6 and IL-6-induced IL-1β release (P < 0.05). Subacute ethanol exposure did not change proinflammatory cytokine release. Acute low-dose ethanol exposure significantly decreased inflammation-induced formation of reactive oxygen species (P < 0.05) and significantly improved cell survival (P < 0.05). Neither acute nor subacute high-dose ethanol exposure significantly changed inflammation-induced changes in reactive oxygen species or survival. Acute and subacute ethanol exposure, independently of the dose, significantly decreased neutrophil adhesion to inflamed Chang liver cells (P < 0.05). Conclusion Acute treatment of inflamed Chang liver cells with ethanol showed its immunosuppressive potential. However, the observed effects were limited to low-dose setting, indicating the relevance of ethanol dose in the modulation of inflammatory cell response.

Abstract
BACKGROUND Intake of ethanol (alcohol) has been shown to influence cardiovascular function; the underlying brain mechanism remains unclear. Noting that nitric oxide (NO) system in the CNS is involved in the regulation of cardiovascular function, the present study examined the role of NO in medulla in ethanol-induced cardiovascular changes. METHODS Ethanol was administered by oral gavage at dose of 3.2 g/kg once every day for 8 consecutive days. Changes in blood pressure (BP) and heart rate (HR) in response to ethanol were measured by radiotelemetry method in freely moving female Sprague-Dawley rats. NO modulators were applied by intracerebroventricular (ICV) injection. The protein levels of nitric oxide synthase (NOS) and NO content in rostroventral medulla were measured by Western blot and nitrate/nitrite colorimetric assay kit, respectively. RESULTS Ethanol intake had little effects on basal BP and HR following 8 consecutive day treatments. A significant increase in HR but not BP following ethanol intake was observed at 6th and 8th, but not at 1st and 4th day treatments as compared with saline group. A decrease in the protein expression of neuronal NOS (nNOS) but not inducible NOS or endothelial NOS and a decline in the level of NO in the medulla 30 min after ethanol administration was observed at 8th day treatment. ICV treatment with NO donors attenuated ethanol-induced tachycardia effects at 8th day treatment. Ethanol produced significantly tachycardia responses when ICV nNOS inhibitors were given at 1st day treatment. CONCLUSION Our results suggest that medulla nNOS/NO pathways play an important role in ethanol regulation of HR.

Abstract
SummaryThere is mounting evidence that zinc, the second most abundant transition metal in blood, is an important mediator of haemostasis and thrombosis. Prompted by the observation that zinc deficiency is associated with bleeding and clotting abnormalities, there now is evidence that zinc serves as an effector of coagulation, anticoagulation and fibrinolysis. Zinc binds numerous plasma proteins and modulates their structure and function. Because activated platelets secrete zinc into the local microenvironment, the concentration of zinc increases in the vicinity of a thrombus. Consequently, the role of zinc varies depending on the microenvironment; a feature that endows zinc with the capacity to spatially and temporally regulate haemostasis and thrombosis. This paper reviews the mechanisms by which zinc regulates coagulation, platelet aggregation, anticoagulation and fibrinolysis and outlines how zinc serves as a ubiquitous modulator of haemostasis and thrombosis.

Abstract
BACKGROUND The clinical relevance of blunt (thoracic) chest trauma (TxT) and hemorrhagic shock is indisputable due to the high prevalence of this injury type, as well as its close association with mortality and/or preventable deaths. Furthermore, there is an ongoing discussion about the influence of alcohol in trauma patients. Thus, we established a model of TxT followed by hemorrhagic shock with resuscitation (H/R) in alcohol-intoxicated rats. METHODS Depending on group allocation, 12 (subacute) or 2 (acute) hours before experimentation, the animals received a single oral dose of alcohol (ethanol [EtOH]) or saline (NaCl) followed by TxT, hemorrhagic shock (35 ± 3 mm Hg), and resuscitation (TxT + H/R). Arterial blood gas analyses and continuous monitoring of blood pressure were performed during the experimentation period. Survival during the experimentation procedure was determined. RESULTS Subacute and acute EtOH group exhibited lower baseline mean arterial blood pressure values compared with the corresponding NaCl group, respectively. Both EtOH groups showed lower maximal bleed-out volume, which was necessary to induce hemorrhagic shock compared to NaCl groups, and the recovery during the resuscitation period was attenuated. During the experimentation in all groups, a trend to acidic pH was observed. Acute EtOH group showed lowest pH values compared to all other groups. Higher pCO2 values were observed in both EtOH groups. All groups developed negative base excess and decreasing HCO3- values until the end of hemorrhagic shock and showed increasing base excess and HCO3- values during resuscitation. Significantly higher mortality rate was found in the acute EtOH group. CONCLUSIONS This study indicates that alcohol limits the metabolic and respiratory compensation capability, thereby promoting mortality.

Abstract
Knowledge about the association between alcohol and Barrett's oesophagus and reflux oesophagitis is conflicting. In this case-control study we evaluated the role of specific alcoholic beverages (red and white wine, beer and liquors) in 339 Barrett's oesophagus and 462 oesophagitis patients compared with 619 endoscopic controls with other disorders, recruited in twelve Italian endoscopic units. Data on alcohol and other individual characteristics were obtained from structured questionnaires. No clear, monotonic significant dose-response relationship was pointed out for red wine. However, a generalised U-shaped trend of Barrett's oesophagus/oesophagitis risk due to red wine consumption particularly among current drinkers was found. Similar results were also found for white wine. Liquor/spirit consumption seemed to bring about a 1·14-2·30 risk excess, although statistically non-significant, for current Barrett's oesophagus/oesophagitis drinkers. Statistically significant decreasing dose-response relationships were found in Barrett's oesophagus for frequency and duration of beer consumption. Similar, but less clear downward tendencies were also found for oesophagitis patients. In conclusion, although often not statistically significant, our data suggested a reduced risk of Barrett's oesophagus and oesophagitis with a low/moderate intake of wine and beer consumption. A non-significant increased risk of Barrett's oesophagus/oesophagitis was observed with a higher intake of any type of heavy alcohol consumption, but no conclusion can be drawn owing to the high number of non-spirit drinkers and to the small number of drinkers at higher alcohol intake levels.

Abstract
Type 2 diabetic mellitus (T2DM) is a disease with high prevalence and a major cause for death worldwide. Diabetic retinopathy (DR) is one of the major manifestation of diabetes. Aldehyde dehydrogenease 2 (ALDH2) detoxifies aldehyde produced during ethanol metabolism and oxidative stress. It has been found that the polymorphism in ALDH2 rs671 is probably associated with the risk of T2DM and DR. However, a lot of inconsistency and controversy still exists. In order to get a more precise and comprehensive estimation for the association between ALDH2 polymorphism with the risk of T2DM and DR, we conducted the present meta-analysis. A comprehensive literature search was conducted using databases, such as Pubmed, Embase, Cochrane Central Register of Controlled Trials, Chinese National Knowledge Infrastructure, and Chinese Biomedical Literature Database, for all related studies. The included studies met the inclusion criteria, such as being case-control studies about the association of ALDH2 polymorphism and T2DM or DR susceptibility, with sufficient data for the present analysis. Eight studies with 2374 cases and 6694 controls were involved in the present meta-analysis. The results indicated a significant lower risk of T2DM for *1/*1 genotype in homozygous models (*1/*1 vs. *2/*2, OR = 0.31, 95% CI = 0.11–0.89, p = 0.03) and in the dominant model (*1/*1 vs. *2/*2 + *1/*2, OR = 0.61, 95% CI = 0.37–1.00, p = 0.05). Subgroup analysis by ethnicity found a significant lower risk of T2DM in Chinese in all genotype models. No significant relation was found between ALDH2 rs671 and DR. In conclusion, the current meta-analysis indicated that ALDH2 rs671 was significantly related with T2DM. The ALDH2 rs671 might be able to be used as a predictor for the risk of T2DM. However, due to the existence of heterogeneity and publication bias in the involved studies, our results should be interpreted with caution.

Abstract
Endothelial progenitor cells (EPCs) and monocytic cells from bone marrow (BM) can be recruited to the injured endothelium and contribute to its regeneration. During metabolic diseases such as obesity and diabetes, progenitor cell function is impaired. Several studies have shown that moderate alcohol consumption prevents the development and progression of atherosclerosis in a variety of animal/mouse models and increases mobilization of progenitor cells. Along with these studies, we identify ethanol at low concentration as therapeutic tool to in vitro expand progenitor cells in order to obtain an adequate number of cells for their use in the treatment of cardiovascular diseases. We evaluated the effects of ethanol on the phenotype of BM-derived cells from mice fed with high-fat diet (HFD). HFD did not induce changes in weight of mice but induced metabolic alterations. HFD feeding increased the differentiation of monocytic progenitors but not EPCs. Whereas ethanol at 0.6% is able to increase monocytic progenitor differentiation, 1% ethanol diminished it. Furthermore, ethanol at 0.6% increased the ability of progenitor cells to promote in vivo angiogenesis as well as secretome of BM-derived cells from mice fed with HFD, but not in mice fed normal diet. In conclusion, ethanol at low concentration is able to increase angiogenic abilities of progenitor cells from animals with early metabolic alterations.

Abstract
Hydroxytyrosol and tyrosol are dietary phenolic compounds present in virgin olive oil and wine. Both compounds are also endogenously synthesized in our body as byproducts of dopamine and tyramine metabolisms, respectively. Over the last decades, research into hydroxytyrosol and tyrosol has experienced an increasing interest due to the role that these compounds may play in the prevention of certain pathologies (e.g. cardiovascular, metabolic, neurodegenerative diseases and cancer). The translation of promising in vitro and in vivo biological effects from preclinical studies to the context of human disease prevention initially depends on whether the dose ingested becomes available at the site of action. In this regard, information regarding the bioavailability and metabolic disposition of hydroxytyrosol and tyrosol is of most importance to evaluate the impact they may have on human health. In this review, we discuss and summarize the state of the art of the scientific evidence regarding the processes of absorption, distribution, metabolism and excretion of both hydroxytyrosol and tyrosol. We also examine the impact of these compounds and their metabolites on biological activity in terms of beneficial health effects. Finally, we evaluate the different analytical approaches that have been developed to measure the plasma and urinary levels of hydroxytyrosol, tyrosol and their metabolites.

Abstract
The consumption of ethanol can have both beneficial and detrimental effects on the function of the heart and cardiovascular system, depending on the amount consumed. Low-to-moderate amounts of ethanol intake are associated with improvements in cardiac function and vascular health. On the other hand, ethanol chronically consumed in large amounts acts as a toxin to the heart and vasculature. The cardiac injury produced by chronic alcohol abuse can progress to heart failure and eventual death. Furthermore, alcohol abuse may exacerbate preexisting heart conditions, such as hypertension and cardiomyopathy. This article focuses on the molecular mechanisms and pathophysiology of both the beneficial and detrimental cardiac effects of alcohol.

Abstract
OBJECTIVES We sought to identify associations between aldehyde dehydrogenase 2 (ALDH2), alcohol consumption, and hypertension in Japanese men. METHODS The study participants were 1,225 male Japanese workers. We collected lifestyle information, body measurements, blood biochemical parameters, blood pressure measurements, and ALDH2 genotyping data during medical examinations conducted between March 2004 and January 2005 at a work facility and an affiliated company. Lifestyle data on alcohol intake and smoking were collected using self-administered questionnaires at the same time as when the aforementioned measurements were obtained. RESULTS The genotype frequencies of ALDH2 genetic polymorphisms were 62.6, 32.7, and 4.7% for *1/*1, *1/*2, and *2/*2, respectively. Systolic blood pressure and diastolic blood pressure in the *1/*2 or *2/*2 group were significantly lower than those in the *1/*1 group (P < 0.001). Multiple regression analysis (stepwise method) for blood pressure according to ALDH2 genetic polymorphism revealed that the amount of daily alcohol intake affected systolic blood pressure in participants who harbored the ALDH2 genetic polymorphism *1/*2 or *2/*2. CONCLUSIONS The interaction between alcohol intake and ALDH2 genetic polymorphisms might affect systolic blood pressure in adult male workers.

Abstract
Recent epidemiological studies suggest that alcohol consumption may reduce renal cell carcinoma (RCC) risk, although inconsistent findings have been reported by sex and alcoholic beverage type. To better understand the relationship between alcohol consumption and RCC risk, we conducted an analysis within the Prostate, Lung, Colorectal and Ovarian Cancer Screening Trial. We followed up participants in the analytic cohort (N = 107,998) through 2010 for incident RCC (N = 408), and computed hazard ratios (HRs) and 95% confidence intervals (CIs) for alcohol intake using Cox regression with adjustment for age, sex, race, study center, hypertension, body mass index, and smoking status. In this study population increasing alcohol consumption was associated with reduced RCC risk compared to non-drinkers (>9.75 g day(-1) : HR, 0.67; 95%CI, 0.50 to 0.89; p trend = 0.002). We observed similar patterns of association for men and women as well as by alcohol beverage type. In analyses stratified by smoking status, the inverse association with consumption was apparent for ever smokers (HR, 0.51; 95%CI, 0.36 to 0.73; p trend<0.0001) but not among never smokers (HR, 1.08; 95%CI, 0.66 to 1.76; P trend = 0.78; p interaction = 0.01). Our study findings offer further support that alcohol consumption is associated with reduced RCC risk, regardless of sex or alcoholic beverage type. The finding of interaction with smoking is novel and requires confirmation.

Abstract
OBJECTIVES Results from studies examining the association between alcohol consumption and the risk of Barrett's esophagus have been inconsistent. We assessed the risk of Barrett's esophagus associated with total and beverage-specific alcohol consumption by pooling individual participant data from five case-control studies participating in the international Barrett's and Esophageal Adenocarcinoma Consortium. METHODS For analysis, there were 1,282 population-based controls, 1,418 controls with gastroesophageal reflux disease (GERD), and 1,169 patients with Barrett's esophagus (cases). We estimated study-specific odds ratios (ORs) and 95% confidence intervals (95% CI) using multivariable logistic regression models adjusted for age, sex, body mass index (BMI), education, smoking status, and GERD symptoms. Summary risk estimates were obtained by random-effects models. We also examined potential effect modification by sex, BMI, GERD symptoms, and cigarette smoking. RESULTS For comparisons with population-based controls, although there was a borderline statistically significant inverse association between any alcohol consumption and the risk of Barrett's esophagus (any vs. none, summary OR=0.77, 95% CI=0.60-1.00), risk did not decrease in a dose-response manner (Ptrend=0.72). Among alcohol types, wine was associated with a moderately reduced risk of Barrett's esophagus (any vs. none, OR=0.71, 95% CI=0.52-0.98); however, there was no consistent dose-response relationship (Ptrend=0.21). We found no association with alcohol consumption when cases were compared with GERD controls. Similar associations were observed across all strata of BMI, GERD symptoms, and cigarette smoking. CONCLUSIONS Consistent with findings for esophageal adenocarcinoma, we found no evidence that alcohol consumption increases the risk of Barrett's esophagus.

Abstract
Background Mitochondrial aldehyde dehydrogenase 2 (ALDH2) detoxifies reactive aldehydes in the micro- and macrovasculature. These substrates, including methylglyoxal and 4-hydroxynonenal formed from glucose and lipids, cause protein carbonylation and mitochondrial dysfunction, forming advanced glycation end products (AGEs). The present study aimed to confirm the association between the inactive ALDH2*2 allele and diabetic retinopathy (DR). Methods A retrospective longitudinal analysis was conducted, among 234 Japanese patients with type 2 diabetes mellitus (DM) (156 males and 78 females) who had no DR signs at baseline and were treated for more than half a year. The ALDH2*1/*2 alleles were determined using a real-time TaqMan allelic discrimination assay. Multivariate-adjusted hazard ratios (HRs) and 95% confidential intervals (CIs) for the cumulative incidence of the development of DR were examined using a Cox proportional hazard model, taking drinking habits and the serum γ-glutamyltransferase (GGT) level into consideration. Results The frequency of the ALDH2*2 allele was 22.3%. Fifty-two subjects cumulatively developed DR during the follow-up period of 5.5 ± 2.5 years. The ALDH2*2 allele carriers had a significantly higher incidence of DR than the non-carriers (HR: 1.92; P = 0.02). The incidence of DR was significantly higher in the drinkers with the ALDH2*2 allele than in those with the ALDH2*1/*1 genotype (HR: 2.61; P = 0.03), while the incidence of DR in the non-drinkers did not differ significantly between the ALDH2 genotype groups (P > 0.05). The incidence of DR was significantly higher in the ALDH2*2 allele carriers with a high GGT level than in the non-carriers with a high or low GGT level (HR: 2.45; P = 0.03; and HR: 2.63; P = 0.03, respectively). Conclusions To the best of our knowledge, this is the first report of a significant association between the ALDH2*2 allele and the incidence of DR. These findings provide additional evidence that ALDH2 protects both microvasculature and macrovasculature against reactive aldehydes generated under conditions of sustained oxidative stress, although further investigations in larger cohorts are needed to verify the results.

Abstract
Since its advent, alcohol has been utilized throughout history socially, for rituals, worship, and for its therapeutic, antibacterial, and analgesic properties. In moderation, alcohol consumption and its use are generally viewed as clinically beneficial. Excessive alcohol consumption on the other hand has been recognized as having several adverse implications. Excessive use increases the risk of liver and heart disease, metabolic disturbances, nutritional deficiencies, certain cancers, brain damage, dementia, neuropathy, as well as other facets of morbidity and mortality. This review targets the sequelae of alcohol consumption on the heart, specifically on myocardial contractility, calcium channel signaling, and intracellular signaling pathways. With the incidence of alcohol-induced cardiac abnormalities being higher than previously thought, it is of increasing importance to elucidate the mechanisms behind them. Here, the cardiac effects of alcohol were not discussed in isolation but in conjunction with other important factors, such as high- and low-density lipoprotein levels and vascular dilatory influences. We explore these mechanisms, in particular, the oxidative stress as the major contributor, as well as pathways that may prove to be cardioprotective. As such, we demonstrate the involvement of nuclear factor (erythroid-derived 2)-like 2 (NFE2L2/NRF2) as well as AKT that act as regulators of oxidative balance during oxidative stress responses. Thus, alcohol consumption may confer a cardioprotective effect when used in moderation through an AKT/NRF2-dependent mechanism.

Abstract
We recently reported that chronic exposure to ethanol lowers blood pressure (BP) via altering cardiac contractility and autonomic control in female rats. In this investigation we conducted pharmacological and molecular studies to elucidate the role of constitutive and inducible nitric oxide synthase (NOS) in these hemodynamic effects of ethanol. Changes caused by selective inhibition of eNOS [N(5)-(1-iminoethyl)-l-ornithine; l-NIO], nNOS (N(ω)-propyl-l-arginine; NPLA), or iNOS (1400W) in BP, heart rate (HR), myocardial contractility index (dP/dt(max)), and power spectral indices of hemodynamic variability were evaluated in telemetered female rats receiving ethanol (5%, w/v) or control liquid diet for 8 weeks. Ethanol increased plasma nitrite/nitrate (NOx) and enhanced the phosphorylation of eNOS and nNOS, but not iNOS, in the tail artery. Ethanol also reduced BP, +dP/dt(max), low-frequency bands of interbeat intervals (IBI(LF), 0.25-0.75 Hz) and IBI(LF/HF) ratio while high-frequency bands (IBI(HF), 0.75-3 Hz) were increased, suggesting parasympathetic overactivity. l-NIO (20 mg/kg i.p.) caused greater increases in BP in control than in ethanol-fed rats but elicited similar reductions in IBI(LF/HF) and +dP/dt(max) both groups. NPLA (1 mg/kg i.p.) caused minimal effects in control rats but exacerbated the reductions in BP, +dP/dt(max), and IBI(LF/HF) in ethanol-fed rats. No hemodynamic modifications were caused by 1400W (5 mg/kg i.p.) in either rat group. Together, these findings suggest that nNOS acts tonically to offset the detrimental cardiovascular actions of ethanol in female rats, and the enhanced vascular NO bioavailability may explain the blunted l-NIO evoked pressor response in ethanol-fed rats.

Abstract
Homocysteine (Hcy) is an accepted independent risk factor for several major pathologies including cardiovascular disease, birth defects, osteoporosis, Alzheimer's disease, and renal failure. Interestingly, many of the pathologies associated with homocysteine are also linked to oxidative stress. The enzyme paraoxonase (PON1) - so named because of its ability to hydrolyse the toxic metabolite of parathion, paraoxon - was also shown early after its identification to manifest arylesterase activity. Although the preferred endogenous substrate of PON1 remains unknown, lactones comprise one possible candidate class. Homocysteine-thiolactone can be disposed of by enzymatic hydrolysis by the serum Hcy-thiolactonase/paraoxonase carried on high-density lipoprotein (HDL). In this review, Hcy and the PON1 enzyme family were scrutinized from different points of view in the literature and the recent articles on these subjects were examined to determine whether these two molecular groups are related to each other like a coin with two different sides, so close and yet so different and so opposite.

Eur J Pharmacol 2012; 679:95-100.

Abstract
Our previous studies showed that the hypotensive effect of chronic ethanol in female rats is reduced by ovariectomy (OVX) rats and was restored after estrogen replacement (OVXE(2)). Further, in randomly cycling rats, chronic ethanol increased cardiac parasympathetic dominance and subsequently reduced myocardial contractility and blood pressure (BP). In this study, we tested the hypothesis that alterations in myocardial contractility and sympathovagal control account for the E(2) exacerbation of the hemodynamic effects of ethanol. BP, myocardial contractility (+dP/dt(max)), and spectral cardiovascular autonomic profiles were evaluated in radiotelemetered OVX, and OVXE(2) rats receiving liquid diet with or without ethanol (5%, w/v) for 13 weeks. In OVX rats, ethanol caused modest hypotension along with significant increases in +dP/dt(max) during weeks 2-5. The high-frequency (IBI(HF), 0.75-3 Hz) and low-frequency (IBI(LF), 0.25-0.75 Hz) bands of interbeat intervals were briefly increased and decreased, respectively, by ethanol. Compared with its effects in OVX rats, chronic treatment of OVXE(2) rats with ethanol elicited significantly greater and more sustained reductions in systolic (SBP) and diastolic (DBP) blood pressures and +dP/dt(max). Altered sympathovagal balance and parasympathetic overactivity were more evident in ethanol-treated OVXE(2) rats as suggested by the sustained: (i) increases in high-frequency bands of interbeat intervals (IBI(HF), 0.75-3 Hz), and (ii) decreases in low-frequency IBI bands (IBI(LF), 0.25-0.75 Hz), IBI(LF/HF) ratio and +dP/dt(max). The plasma ethanol concentration was not affected by changes in the hormonal milieu. These findings suggest that estrogen exacerbates the ethanol-evoked reductions in myocardial contractility and BP and the associated parasympathetic overactivity in female rats.

Abstract
Oral ingestion of monosodium glutamate (MSG) to chronic alcoholic adult male mice at dose levels of 4 and 8 mg/g body weight for seven consecutive days caused a significant increase in lipid fractions, lipid peroxidation, xanthine oxidase, whereas the levels of superoxide dismutase, catalase, glutathione, and its metabolizing enzymes like glutathione peroxidase and glutathione reductase were significantly decreased in the arterial tissue. These observations suggested that ingestion of MSG to chronic alcoholic animals had no beneficial effect and thereby, could act as an additional factor for the initiation of atherosclerosis.

Abstract
We investigated the role of reactive oxygen species (ROS) and nitric oxide (NO) in ethanol-induced relaxation. Vascular reactivity experiments showed that ethanol (0.03-200 mmol/L) induced relaxation in endothelium-intact and denuded rat aortic rings isolated from male Wistar rats. Pre-incubation of intact or denuded rings with l-NAME (non selective NOS inhibitor, 100 μmol/L), 7-nitroindazole (selective nNOS inhibitor, 100 μmol/L), ODQ (selective inhibitor of guanylyl cyclase enzyme, 1 μmol/L), glibenclamide (selective blocker of ATP-sensitive K(+) channels, 3 μmol/L) and 4-aminopyridine (selective blocker of voltage-dependent K(+) channels, 4-AP, 1 mmol/L) reduced ethanol-induced relaxation. Similarly, tiron (superoxide anion (O(2)(-)) scavenger, 1 mmol/L) and catalase (hydrogen peroxide (H(2)O(2)) scavenger, 300 U/mL) reduced ethanol-induced relaxation to a similar extent in both endothelium-intact and denuded rings. Finally, prodifen (non-selective cytochrome P450 enzymes inhibitor, 10 μmol/L) and 4-methylpyrazole (selective alcohol dehydrogenase inhibitor, 10 μmol/L) reduced ethanol-induced relaxation. In cultured aortic vascular smooth muscle cells (VSMCs), ethanol stimulated generation of NO, which was significantly inhibited by l-NAME. In endothelial cells, flow cytometry studies showed that ethanol increased cytosolic Ca(2+) concentration ([Ca(2+)]c), O(2)(-) and cytosolic NO concentration ([NO]c). Tiron inhibited ethanol-induced increase in [Ca(2+)]c and [NO]c. The major new finding of this work is that ethanol induces relaxation via redox-sensitive and NO-cGMP-dependent pathways through direct effects on ROS production and NO signaling. These findings identify putative molecular mechanisms whereby ethanol, at pharmacological concentrations, influences vascular reactivity.

Abstract
BACKGROUND A moderate intake of alcohol is associated with lower cardiovascular mortality, and the role of circulating progenitor cells in the beneficial effect of alcohol on atherosclerosis is unclear. The hypothesis of this study was that alcohol ameliorates atherosclerosis by modulating the circulating levels of stromal cell-derived growth factor (SDF)-1 and vascular progenitor cells. METHODS AND RESULTS Atherosclerosis was induced by infusion of angiotensin II in apolipoprotein-E deficient mice, which were treated with high and low doses of ethanol for 28 days by intraperitoneal injection. Mice treated with low-dose ethanol had significantly less dilatation and fewer atheromatous lesions than mice receiving the high-dose ethanol. The number of circulating fibrocytes was significantly lower in mice treated with high-dose ethanol compared with mice with atherosclerosis untreated with ethanol. The plasma CXCL12/SDF-1 level was significantly increased in mice treated with low-dose ethanol compared with mice treated with a high dose, and the plasma concentration of transforming growth factor-β1 was significantly increased in mice treated with high-dose ethanol compared with control mice. Ethanol regulated the secretion of SDF-1 and vascular endothelial growth factor from fibroblasts in a dose-dependent and bimodal fashion. CONCLUSIONS The circulating level of CXCL12/SDF-1 may be involved, at least in part, in the differential effects of alcohol consumption on atherosclerosis.

Abstract
OBJECTIVES Alcohol is a carcinogen that may increase the risk of Barrett's esophagus (BE) through direct contact with esophageal mucosa. However, few studies have investigated this association and findings have been inconsistent. We sought to examine the association between measures of total and beverage-specific alcohol consumption and BE risk. METHODS We conducted a large population-based case-control study that collected information on lifetime alcohol consumption and other exposures from 285 patients with nondysplastic BE, 108 patients with dysplastic BE, and two separate control groups: 313 endoscopy patients with acute inflammatory changes ("inflammation controls") and 644 population controls. We calculated odds ratios (ORs) and 95% confidence intervals (CIs) for categories of average alcohol consumption using unconditional multivariate logistic regression. RESULTS Relative to life-long nondrinkers and consumption of <1 drink/week, consumption of 7-20 drinks/week (OR=0.53, 95% CI: 0.31-0.91) and 21-41 drinks/week (OR=0.37, 95% CI: 0.19-0.73) of total alcohol throughout the life was inversely associated with nondysplastic BE, for comparisons with population controls. Lifetime total alcohol consumption was also inversely associated with dysplastic BE (7-20 drinks/week OR=0.52, 95% CI: 0.19-1.43; 21-41 drinks/week OR=0.22, 95% CI: 0.07-0.73). Similarly, reduced risk estimates were found for comparisons with inflammation controls. The inverse associations were observed separately for beer and wine consumption, with a significant linear trend observed with beer consumption. The risks associated with liquor consumption were up to twofold higher; however, they were not statistically significant. We found no evidence for effect modification by factors known (or suspected) to cause BE. CONCLUSIONS Overall, alcohol consumption does not increase the risk of BE. Significant inverse associations were observed for beer consumption, the underlying reasons for which remain unclear.

Abstract
OBJECTIVES This study examined the association between alcohol use, the occurrence of cardiovascular events, and plaque phenotype in patients after femoral or carotid endarterectomy for arterial occlusive disease. Alcohol has been shown to have cardiovascular protective effects in patients with cardiovascular disease as well as in healthy individuals. Whether alcohol consumption induces changes in atherosclerotic plaque composition has not been investigated. METHODS Consecutive femoral (n = 224) and carotid (n = 693) endarterectomy specimens underwent histologic examination for the presence of collagen, calcifications, smooth muscle cells, macrophages, fat, and intraplaque thrombus. Patients were monitored for 3 years after the initial operation and investigated for the occurrence of cardiovascular events. Primary outcome was the composite end point "major cardiovascular event." Alcohol consumption was categorized as no alcohol use, 1 to 10 U/wk, or >10 U/wk. RESULTS The Kaplan-Meier estimate of the major cardiovascular event rate after 3 years of follow-up in the femoral group was 35% for no alcohol use and 21% for 1 to 10 U/wk, whereas only 10% of the group >10 U/wk sustained a major cardiovascular event (P = .010). The plaques of alcohol consumers in the femoral group contained significantly smaller lipid cores and less macrophage infiltration than in abstainers. In the carotid group, the major cardiovascular event rate was similar in all three groups, and in addition, no difference in plaque composition was observed. CONCLUSIONS This study shows an inverse relationship between alcohol use and major cardiovascular events after endarterectomy for lower extremity arterial occlusive disease, accompanied by a more stable plaque phenotype. However, no such relationship could be observed for patients with cerebrovascular disease.

Abstract
Arrhythmogenic effects of alcohol may be intermediated by its effects over heart rate variability (HRV). Most studies about the effects of alcohol over HRV were observational and did not explore the temporal influence of alcohol ingestion over autonomic modulation. The aim of this study was to verify if an acute ingestion of alcohol has a time-dependent influence over time-domain indices of HRV. The effect of the ingestion of 60 g of ethanol or placebo over autonomic modulation was compared in healthy men (35 per group), with 18-25 years of age, before and during 17 h after ingestion. Alcohol promoted a fall in the standard deviation of all normal R-R intervals, root mean square of successive differences, and percentage of pairs of adjacent R-R intervals differing by more than 50 ms and in two indices of the three-dimensional return map, by a period up to 10 h after the ingestion of alcohol, accompanied by an increase in heart rate. The indices returned to values similar of the control group 10 h after ingestion. The effects over HRV indices were attenuated by adjustment for heart rate. The ingestion of alcohol induces a broad cardiovascular adaptation secondary to vagal withdrawal and sympathetic activation that may be responsible for arrhythmogenic effects of alcohol ingestion.

Abstract
Our previous studies have shown that acute alcohol intoxication (AAI) decreases blood pressure, exacerbates hypotension after hemorrhagic shock, impairs the pressor response to fluid resuscitation, and blunts neuroendocrine activation. We hypothesized that impaired hemodynamic compensation during and after hemorrhagic shock in the acute alcohol-intoxicated host is the result of blunted neuroendocrine activation or, alternatively, of an impaired vascular responsiveness to vasoactive agents. The aim of this study was to examine the effects of AAI, AAI and hemorrhagic shock, and AAI and hemorrhagic shock and resuscitation on reactivity of isolated blood vessel rings to phenylephrine and acetylcholine. Chronically instrumented, conscious male Sprague-Dawley rats (300-350 g) received a primed continuous 15-h intragastric alcohol infusion (2.5 g x kg(-1) + 300 mg x kg(-1) x h(-1)), and time-matched controls received an isocaloric-isovolumic dextrose infusion. At completion of infusions, animals were randomized to sham, 60-min fixed-pressure hemorrhage, or hemorrhagic shock followed by resuscitation with lactated Ringer's solution. At the completion of the experimental protocols, animals were killed, and thoracic aorta and mesenteric artery ring segments (1-2 mm) were prepared and studied in myograph baths. Acute alcohol intoxication did not produce significant alterations in either pressor or dilator responses in aortic or mesenteric rings. These findings suggest that impaired hemodynamic counterregulation during hemorrhagic shock in AAI is not due to decreased vasopressor responsiveness. However, our results suggest a role for accentuated vasodilatory responses that may be central in progression to decompensatory shock.

Abstract
The beneficial effect of the '1-drink-a-day' lifestyle is suggested by studies of cardiovascular health, and this recommendation is increasingly followed in many countries. The main objective of this study was to determine whether this pattern of ethanol use would be detrimental to a pregnant woman. We exposed a primary culture of rat cerebellum from embryonic day 17 (corresponding to second trimester in humans) to ethanol at a concentration of 17.6 mM which is roughly equivalent to one glass of wine. Acutely, there was no change in cell viability after 5 or 8 days of exposure relative to control. By 11 days, a reduction in the number of viable cells was observed without an accompanying change in caspase-3 activity (marker of apoptotic cell death), suggesting changes in cell proliferation. As the proportion of nestin-positive cells was higher in the ethanol-treated cultures after 5 days, we hypothesized that an increase in differentiation to neurons would compensate for the ongoing neuronal death. However, there were limits to this compensatory ability as the relative proportion of nestin-positive cells was decreased after 11 days. To further illustrate the negative long-term effects of this ethanol dose, cultures were exposed for 30 days. After this period, virtually no neurons or myelinating oligodendrocytes were present in the ethanol-treated cultures. In conclusion, chronic exposure to ethanol, even at small doses, dramatically and persistently affects normal development.

Abstract
A mérsékelt alkoholfogyasztás csökkenti a cardiovascularis és 2-es típusú diabetes kockázatát. Ennek az epidemiológiai megfigyelésnek a magyarázata azonban még nem pontosan ismert. Az alkohol emeli a high-density lipoprotein (HDL) koleszterin szintjét. Felmerültek egyéb mechanizmusok is, úgymint a gyulladás- és thrombosisgátló hatások. A mérsékelt alkoholfogyasztás és inzulinérzékenység közötti kapcsolat még vitatott. A lehetséges mechanizmusok közé tartoznak az adiponektinszint emelése, a C-reaktív protein csökkentése és a szabad zsírsav zsírszövetből történő kiáramlásának csökkentése is.
