Perfusate biomarker concentrations

had no relevant correlation with cold ischemic time or renal vascular resistance on the pump.\n\nConclusions. Increased GST, NAG, or H-FABP concentrations during MP are an indication to adjust posttransplant recipient management. However, this study shows for the first time that perfusate biomarker measurements should not lead to kidney discard.”
“Free-breathing image acquisition is desirable in first-pass gadolinium-enhanced magnetic resonance imaging (MRI), selleck products but the breathing movements hinder the direct automatic analysis of the myocardial perfusion and qualitative readout by visual tracking. Nonrigid registration can be used to compensate for these movements but needs to deal with local contrast and intensity changes with time. We propose an automatic registration scheme that exploits the quasiperiodicity

of free breathing to decouple movement from intensity change. First, we identify and register a subset of the images corresponding to the same phase of the breathing cycle. This registration step deals with small differences caused by movement but maintains the full range of intensity change. The remaining images are then registered to synthetic references that are created as a linear combination of images AZD9291 belonging to the already registered subset. Because of the quasiperiodic respiratory movement, the subset images are distributed evenly over time and, therefore, the synthetic references exhibit intensities similar to their corresponding unregistered images. Thus, this second registration step needs to account only for the movement. Validation experiments were performed on data obtained from AC220 six patients, three slices per patient, and the automatically obtained perfusion profiles were compared with profiles obtained by manually segmenting the myocardium. The results show that our automatic approach is well suited to compensate for the free-breathing movement and that it achieves a significant improvement in the average Pearson correlation coefficient between manually and automatically

obtained perfusion profiles before (0.87 +/- 0.18) and after (0.96 +/- 0.09) registration.”
“Rationale, aims and objectives There are a variety of resources to obtain health information, but few studies have examined if main and allied health professionals prefer different methods. The current study was to investigate their information-searching behaviours. Methods A constructed questionnaire survey was conducted from January through April 2011 in nationwide regional hospitals of Taiwan. Questionnaires were mailed to main professionals (physicians and nurses) and allied professionals (pharmacists, physical therapists, technicians and others), with 6160 valid returns collected. Results Among all professional groups, the most commonly used resource for seeking health information was a Web portal, followed by colleague consultations and continuing education.
