We previously reported a negative association of circulating plasmalogens (phospholipids with proposed atheroprotective properties) with coronary artery disease. Plasmalogen modulation was previously demonstrated in animals but its effect on atherosclerosis was unknown. We assessed the effect of plasmalogen enrichment on atherosclerosis of murine models with differing levels of oxidative stress.', 'Six-week old ApoE- and ApoE/glutathione peroxidase-1 (GPx1)-deficient mice were fed a high-fat diet with/without 2% batyl alcohol (precursor to plasmalogen synthesis) for 12 weeks. Mass spectrometry analysis of lipids showed that batyl alcohol supplementation to ApoE- and ApoE/GPx1-deficient mice increased the total plasmalogen levels in both plasma and heart. Oxidation of plasmalogen in the treated mice was evident from increased level of plasmalogen oxidative by-product, sn-2 lysophospholipids. Atherosclerotic plaque in the aorta was reduced by 70% (P\xa0=\xa05.69E-07) and 69% (P\xa0=\xa02.00E-04) in treated ApoE- and ApoE/GPx1-deficient mice, respectively. A 40% reduction in plaque (P\xa0=\xa07.74E-03) was also seen in the aortic sinus of only the treated ApoE/GPx1-deficient mice. Only the treated ApoE/GPx1-deficient mice showed a decrease in VCAM-1 staining (-28%, P\xa0=\xa02.43E-02) in the aortic sinus and nitrotyrosine staining (-78%, P\xa0=\xa05.11E-06) in the aorta.

Morbidly obese patients usually present vitamin D deficiency or secondary hyperparathyroidism. Low vitamin D levels have been recently related to non-alcoholic fatty liver disease (NAFLD). The aim of this study was to analyse the relationship between vitamin D, bone turnover markers and non-alcoholic fatty liver disease and metabolic syndrome in severely obese patients.', 'One hundred and ten patients who underwent bariatric surgery were included. Liver biopsy was taken during surgery. Two univariate analyses were carried out in order to i) analyse the relationship between liver histology and vitamin D-bone turnover markers (intact parathyroid hormone (PTH), osteocalcin and Carboxy-terminal collagen crosslinks) and ii) establish the association between metabolic syndrome components-insulin resistance (HOMA) and vitamin D-bone turnover markers.', '70% of the patients had lower levels of vitamin D or secondary hyperparathyroidism. None of the components of liver histology were associated with levels of vitamin D or with bone turnover parameters. Patients with metabolic syndrome showed lower levels of PTH and osteocalcin (72,42 (29,47) vs 61.25(19.59) p-Value: 0.022; 19.79 (10.43) vs 16.87(10.25) p-Value: 0,028, respectively). HOMA was not related to Vitamin D or bone turnover markers.

Activation of Kupffer cells by gut-derived endotoxin plays a pivotal role in alcoholic liver injury. On the other hand, it was reported that acute ethanol administration reduced activation of Kupffer cells. We found that Kupffer cells isolated from rat treated only once with ethanol were sensitized to endotoxin 24 hrs later correlatively with CD14 expression. Moreover, it was shown that Kupffer cell activation by endotoxin via Toll-like receptor (TLR)-4 is involved in alcohol-induced liver injury and ethanol-induced oxidative stress is important in the regulation of transcription factor NFkappaB activation and cytokine production by Kupffer cells. Here, we show that IRAK, one of signaling molecules of TLR-4, regulates tolerance and sensitization to LPS and acute ethanol increases in IRAK expression through a mechanism dependent upon oxidant production.', 'Female C57BL/6 mice were given ethanol (5 g/kg) intragastrically, and LPS was injected 1 or 21 hrs later. Serum transaminase levels were measured. Moreover, some mice were treated with NADPH oxidase inhibitor diphenyleneiodonium sulfate (DPI, 1 mg/kg/day) or infected with adenovirus (1 x 10 plaque-forming units, intravenously) containing IkappaB superrepressor gene, which prevent NFkappaB activation of Kupffer cells, for three days. Kupffer cells were isolated from mice 1 hr and 21 hrs after ethanol treatment. After the addition of LPS, TNF-alpha in the media was measured using ELISA, Electrophoretic mobility shift assay (EMSA) was performed to analyze DNA binding activity of NFkappaB. Further, expression of Interleukin-1 receptor-associated kinase (IRAK) was evaluated by Western blotting.', 'LPS-induced increases in transaminases were blunted in mice treated with ethanol before 1 hr. However, ethanol treatment 21 hrs earlier augmented LPS-increased transaminases three-fold over controls. Pretreatment with nonabsorbable antibiotics blocked these effects of ethanol. LPS-induced TNF-alpha production by Kupffer cells isolated from mice 1 hr after ethanol was reduced to about 60% of values from control Kupffer cells, while LPS-induced TNF-alpha production by Kupffer cells isolated from mice treated with ethanol 21 hrs earlier increased 1.5-fold over control Kupffer cells. In Kupffer cells from mice 1 hr after ethanol treatment, expression of IRAK was decreased, and LPS-induced activation of NFkappaB was decreased correlatively. In contrast, ethanol treatment to mice increased expression of IRAK in Kupffer cells 21hrs later and LPS-induced activation of NFkappaB was elevated significantly. On the other hands, DPI treatment for three days prior to ethanol did not prevent decreases in IRAK expression due to ethanol treatment for 1 hr. However, DPI treatment blunted ethanol-induced increases in IRAK expression. Additionally, inhibition of NKkappaB activation with dominant-negative IkappaBalpha blunted ethanol-induced increase in IRAK expression. Contrary, inhibition of NKkappaB did not affect decrease of IRAK expression due to ethanol treatment for 1 hr.
