Tumor Necrosis Factor α Receptors (TNFR) 1 and 2 were measured with the MS2400 TNFR1 and TNFR2 ultrasensitive assay (Meso Scale Discovery,

MD, USA). Plasma concentrations AZD6244 of Macrophage Chemoattractant Protein 1 (MCP1) were measured with the MA2400 Human MCP1 ultrasensitive assay (Meso Scale Discovery, MD, USA). Soluble endothelial selectin (sE-selectin) concentrations were measured by enzyme-linked immunosorbent assay (ELISA) as described [9]. Plasma Tumor Necrosis Factor α (TNFα) and interleukin 6 (IL6) were measured with an ELISA kit from R&D systems (Abingdon, UK). All samples from one subject were analyzed in the same analytical run in duplicate. The intra- and inter-assay variation coefficients were below 10% for all measured parameters. The power to detect a true difference of 0.20 mmol/L in triglyceride concentrations between treatments after adjustment for multiple comparisons was 80%. Normality was checked visually and tested with the Shapiro–Wilk test. Glucose and sE-selectin concentrations

were log transformed to achieve normality. Differences in fasting levels at the end of the intervention periods were compared with a General Linear Model for Univariate ANOVA with treatment as fixed factor and subject number as random factor. Since there were no significant interactions between treatment and gender, and treatment and body weight on the outcome parameters, these parameters were not included in the final model. To adjust for multiple comparisons, a Tukey Honestly GSK126 solubility dmso Significantly Difference (HSD) procedure was carried out. A P < 0.05 was considered to be statistically Thiamine-diphosphate kinase significant. Data are presented as mean ± SD. Statistical analysis was performed using SPSS 15.0 for Windows. The calculated main daily capsule intake was 93% during the fish oil period, 95% during the fenofibrate

period and 95% during the placebo period, indicating a good compliance. This was confirmed for the fish oil period, as plasma free EPA and DHA concentrations increased by 358% (P < 0.001) and 105% (P < 0.001) compared to the placebo period, and by 463% (P < 0.001) and 157% (P < 0.001) compared to the fenofibrate period, respectively. Total energy intake and the proportions of energy from fat, carbohydrates and protein, and the amounts of fiber, alcohol and cholesterol in the diet did not differ between the treatment groups (data not shown). Furthermore, body weight and blood pressure did not change between the treatment periods (data not shown). Compared to placebo, fenofibrate reduced serum total cholesterol and LDL cholesterol by respectively 9% (−0.59 mmol/L, P = 0.001) and 11% (−0.45 mmol/L, P = 0.004; Table 2). Fish oil tended to increase the concentration of total cholesterol (P = 0.099) and increased that of LDL cholesterol by 10% (0.34 mmol/L, P = 0.035) compared to placebo.
