Abstract
Citrus limon (lemon) possesses immunoregulatory, antioxidant, and lipid-lowering effects. Our previous study showed that lemon fermented products (LFP) which were lemon fermented with Lactobacillus OPC1 had the ability to avert obesity. However, the LFP effects on the pathway of lipid metabolism by gut microbiota were still unclear. This study was aimed to investigate the LFP effects on liver lipid metabolism and gut microbiota in a rat model of obesity caused by a high-calorie diet. LFP effectively reduced the total triglyceride (49.7%) and total cholesterol (53.3%) contents of the liver. Additionally, the mRNA levels of genes related to triglyceride metabolism (SREBP-1c, PPARγ, and ACC), cholesterol metabolism (HMG-CoA reductase, ACAT, and LCAT), and lipid β-oxidation (PPARα, and CPT-1) were regulated by LFP. Furthermore, LFP reduced the ratio of Firmicutes/Bacteroidetes and enhanced the ratio of Firmicutes Clostridia. Overall, these findings suggested that LFP might use as a potential dietary supplement for preventing obesity by modulating the lipid metabolism and improving the gut microbiota.

Abstract
PURPOSE Several studies have reported an inverse association between moderate alcohol consumption and prevalence of fatty liver (FL) in men. We aimed to clarify this association in women. METHODS We collected health checkup data from 4,921 Japanese women without concurrent liver disease (mean age 46.4 years) and performed a cross-sectional study to evaluate the influence of alcohol drinking patterns (frequency and amount) on the prevalence of FL as assessed by ultrasonography. RESULTS Alcohol consumption was reported in 30.8 % of participants, and FL was observed in 13.8 % (15.5 % nondrinkers, 10.1 % drinkers). Alcohol consumption was inversely associated with FL prevalence [adjusted odds ratio (AOR) 0.79, 95 % confidence interval (CI) 0.63-0.98]. In analyses stratified by drinking frequency and/or amount of alcohol consumed, the risk of FL decreased for the following categories: 0.1-19.9 g/drinking day (AOR 0.61, 95 % CI 0.44-0.83) and 0.1-69.9 g/week (AOR 0.74, 95 % CI 0.55-0.98). The amount of alcohol consumed directly correlated with the prevalence of FL in daily drinkers (p < 0.05), whereas there was no correlation between the frequency of alcohol consumption and FL prevalence. Alanine aminotransferase levels were significantly lower for the following categories: 0.1-19.9 g/drinking day for 1-3 days a week (p = 0.016) and 0.1-69.9 g within 1-3 drinking days a week (p = 0.004). CONCLUSIONS Minimal alcohol consumption appears to have protective effects against nonalcoholic FL disease in women, although an increase in the amount of alcohol consumed appears to nullify the protective effect.

The effect of alcohol on atherosclerotic plaque composition and cardiovascular events in patients with arterial occlusive disease. J Vasc Surg 2011; 54:123-31. [PMID: 21367564 DOI: 10.1016/j.jvs.2010.12.039] [Citation(s) in RCA: 8] [Impact Index Per Article: 0.6] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/17/2010] [Revised: 12/08/2010] [Accepted: 12/08/2010] [Indexed: 11/21/2022]
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
BACKGROUND Moderate alcohol consumption may have certain beneficial effects against non-alcoholic fatty liver disease, which is associated with metabolic syndrome. AIM To determine the association between drinking pattern and fatty liver in Japanese men and women. METHODS A cross-sectional study was performed with health checkup data including information concerning alcohol consumption and ultrasonographic assessment of fatty liver. RESULTS We analysed 4957 men and 2155 women without reported liver diseases (median age, 49 years). In men, 40% of nondrinkers and 28% of drinkers had fatty liver. Alcohol consumption was inversely associated with fatty liver (adjusted odds ratio, 0.54; 95% confidence interval, 0.46-0.63). The prevalence of fatty liver in each category of drinking frequency was 38% (1-3 days/week), 29% (4-6 days/week), and 24% (daily drinking); there was a significant inverse correlation between drinking frequency and the prevalence of fatty liver (P < 0.001). In women, 16% of nondrinkers and 10% of drinkers had fatty liver. Drinking less than 20 g on 1-3 days/week was associated with low prevalence of fatty liver (adjusted odds ratio, 0.47; 95% confidence interval, 0.23-0.96). CONCLUSIONS Alcohol consumption appears to protect against non-alcoholic fatty liver disease.

Abstract
Polyphenols exert beneficial effects in atherosclerosis. The crucial step in atherosclerosis is the recruitment of monocytes to the subendothelial space, induced by endothelial adhesion molecules through the activation of factors such as NF-κB. We studied the effect of a dealcoholised lager beer (DLB) and a dealcoholised dark beer (DDB) on atherosclerotic lesions, and the underlying mechanisms. Dealcoholised beers were administered in the diet (42 ml/kg body weight per d) to 4-week-old male apoE knockout (apoE - / - ) mice for 20 weeks. The atherosclerotic lesions in the thoracic aorta were reduced by 44 % (P = 0·003) and 51 % (P < 0·001) in DLB- and DDB-treated mice, respectively. Also, the mRNA expressions of the endothelial adhesion molecules in the total aorta were decreased: P-selectin showed a 17 % (P = 0·004) reduction in DDB-treated mice; vascular cell adhesion molecule-1 (VCAM-1) was decreased by 20 % (P = 0·012) and 32 % (P = 0·001) in DLB- and DDB-treated mice, respectively; intercellular adhesion molecule-1 (ICAM-1) showed a 14 % (P = 0·014) reduction in DLB-treated mice. The protein expressions of these molecules and NF-κB were studied in the aortic root. P-selectin was decreased by 37 % (P = 0·012) in DDB-treated mice; VCAM-1 was reduced by 48 % (P = 0·001) and 54 % (P < 0·001) in DLB- and DDB-treated mice, respectively; ICAM-1 was decreased by 25 % (P = 0·028) and 30 % (P = 0·018) in DLB- and DDB-treated mice, respectively; NF-κB was reduced by 46 % (P = 0·042) in DDB-treated mice. In conclusion, dealcoholised beers protected apoE - / - mice against atherosclerosis, through the modulation of endothelial adhesion molecules, possibly induced by NF-κB.

Abstract
Alcohol abuse is a global problem due to the financial burden on society and the healthcare system. While the harmful health effects of chronic alcohol abuse are well established, more recent data suggest that acute alcohol consumption also affects human wellbeing. Thus, there is a need for research models in order to fully understand the effect of acute alcohol abuse on different body systems and organs. The present manuscript summarizes the interdisciplinary advantages and disadvantages of currently available human and non-human models of acute alcohol abuse, and identifies their suitability for biomedical research.

Abstract
OBJECTIVES There is substantial epidemiological data suggesting a J- or U-shaped association between alcohol consumption and coronary events. However, some studies in experimental animals suggest that alcohol may increase atherosclerosis. Therefore, our aim was to study whether alcohol consumption is associated with carotid intima-media thickness (IMT), marker of subclinical atherosclerosis, in young, healthy adults. METHODS Alcohol consumption, carotid IMT and conventional cardiovascular risk factors were investigated in 2074 subjects, aged 24-39 years. RESULTS In subjects consuming none, >0 to <2, 2 to <4 or >or=4 units of alcohol per day, the respective carotid IMT values were 0.57+/-0.004, 0.59+/-0.003, 0.59+/-0.006, and 0.60+/-0.012 mm (mean+/-S.E.M., P<0.0001 for increasing IMT trend across alcohol consumption categories). This direct association between alcohol consumption and IMT was independent of age, sex and several cardiovascular risk factors, e.g. blood pressure, LDL-cholesterol, HDL-cholesterol, BMI, smoking, CRP and insulin (P=0.008 in multivariable regression model). The frequencies of drinking wine or strong alcohol beverages (respective P-values 0.03 and 0.01 for increasing IMT trend across beverage consuming frequency) were directly correlated with carotid IMT in models adjusted for age, sex and risk factors. CONCLUSIONS We found a direct relationship between alcohol consumption and carotid IMT in young adults. This association was independent of cardiovascular risk factors suggesting that in young healthy adults alcohol consumption may have pro-atherogenic effects.

Abstract
Rats with carnitine deficiency due to trimethylhydrazinium propionate (mildronate) administered at 80 mg/100 g body weight per day for 10 days developed liver steatosis only upon fasting. This study aimed to determine whether the transient steatosis resulted from triglyceride accumulation due to the amount of fatty acids preserved through impaired fatty acid oxidation and/or from up-regulation of lipid exchange between liver and adipose tissue. In liver, mildronate decreased the carnitine content by approximately 13-fold and, in fasted rats, lowered the palmitate oxidation rate by 50% in the perfused organ, increased 9-fold the triglyceride content, and doubled the hepatic very low density lipoprotein secretion rate. Concomitantly, triglyceridemia was 13-fold greater than in controls. Hepatic carnitine palmitoyltransferase I activity and palmitate oxidation capacities measured in vitro were increased after treatment. Gene expression of hepatic proteins involved in fatty acid oxidation, triglyceride formation, and lipid uptake were all increased and were associated with increased hepatic free fatty acid content in treated rats. In periepididymal adipose tissue, mildronate markedly increased lipoprotein lipase and hormone-sensitive lipase activities in fed and fasted rats, respectively. On refeeding, carnitine-depleted rats exhibited a rapid decrease in blood triglycerides and free fatty acids, then after approximately 2 h, a marked drop of liver triglycerides and a progressive decrease in liver free fatty acids. Data show that up-regulation of liver activities, peripheral lipolysis, and lipoprotein lipase activity were likely essential factors for excess fat deposit and release alternately occurring in liver and adipose tissue of carnitine-depleted rats during the fed/fasted transition.

Abstract
This study explores the mechanisms responsible for the fatty liver setup in mice fed trans-10,cis-12 conjugated linoleic acid (t10c12 CLA), hypothesizing that an induction of low density lipoprotein receptor (LDLR) expression is associated with lipid accumulation. To this end, the effects of t10c12 CLA treatment on lipid parameters, serum lipoproteins, and expression of liver lipid receptors were measured in LDLR(-/-) apoB(100/100) mice as a model of human familial hypercholesterolemia itself depleted of LDLR. Mice were fed t10c12 CLA over 2 or 4 weeks. We first observed that the treatment induced liver steatosis, even in the absence of LDLR. Mice treated for 2 weeks exhibited hypertriglyceridemia with high levels of VLDL and HDL, whereas a 4 week treatment inversely induced a reduction of serum triglycerides (TGs), essentially through a decrease in VLDL levels. In the absence of LDLR, the mRNA levels of other proteins, such as VLDL receptor, lipoprotein lipase, and fatty acid translocase, usually not expressed in the liver, were upregulated, suggesting their involvement in the steatosis setup and lipoprotein clearance. The data also suggest that the TG-lowering effect induced by t10c12 CLA treatment was attributable to both the reduction of circulating free fatty acids in response to the severe lipoatrophy and the high capacity of liver to clear off plasma lipids.
