It was found that the single-layer model based on homogeneous wall assumption could not reproduce the validation data. In contrast, the constrained bi-layer model was in excellent agreement with both types of experimental data. Due to covariance, estimations of fiber angle were slightly outside of the normal range, which can be resolved by predefining the angles to normal values. Our approach is relatively invariant to a constant or a variable axial response. We believe that it is suitable for in-vivo characterization.”
“Cereals products for direct human consumption are rarely contaminated by moulds, unlike raw materials, which are often infected, click here either in the field

or during storage.\n\nIn this study, 27 samples of dried pasta characterised by size, packaging and marketing intended for young children consumption were collected and analysed by liquid chromatography (LC) and liquid chromatography-tandem mass spectrometry (LC-MS/MS) for Deoxynivalenol Duvelisib nmr (DON), Ochratoxin A (OTA) and Aflatoxin B-1 (AFB(1)) determination. The samples that showed the highest amounts of one of the mycotoxins were cooked for 10 min, digested with an in vitro gastrointestinal protocol and bioaccessibility values were calculated. Seven of the 27 samples exceeded from 120% to 225% the legal limit of 200 mu g/kg for DON fixed for processed cereal-based baby foods by an European Regulation: all the collected samples were under the OTA legal

limit (0.05 mu g/kg) fixed by the European Regulation and no sample was contaminated by AFB(1) over the instrumental limit of detection GDC-0068 of 0.10 mu g/kg. The mean value of gastric bioaccessibility verified for the DON resulted of 23.1%, whereas mean duodenal bioaccessibility was 12.1%. (C) 2011 Elsevier Ltd. All rights reserved.”
“Study Objective To determine whether pharmacologic prophylaxis for venous thromboembolism (VTE) was associated with a decrease in the incidence of VTE or an increased incidence of bleeding in patients with chronic liver disease (CLD). Design Single-center, retrospective cohort analysis. Setting University medical center. Patients A total of 1581 adults with CLD hospitalized over a

3-year period for longer than 24hours. Measurements and Main Results Medical records were reviewed for the primary outcome of VTE and documented episodes of bleeding during hospitalization and were divided into two groups based on receipt of pharmacologic VTE prophylaxis. During the 1581 hospitalizations, 392 (24.7%) patients received pharmacologic VTE prophylaxis. The incidence of VTE in the prophylaxis group was 0.5% compared with 1.8% in patients without prophylaxis (p=0.05). Documented bleeding rates were lower in the prophylaxis group (2.0% vs 10.3%, p<0.001). Multivariate logistic regression identified active malignancy (odds ratio [OR] 8.76, 95% confidence interval [CI], 2.5629.58), trauma or surgery during hospitalization (OR 10.29, 95% CI 1.1889.
