The pathophysiological relevance and therapeutic potential remains to be determined, but dual effects of P2Y(2) receptor activation on both the vasculature Dibutyryl-cAMP and renal salt reabsorption implicate these receptors as potential therapeutic targets in hypertension.”
“[F-18] fluoro-2-deoxy-D-glucose positron emission tomography (FDG-PET) is increasingly used for response assessment in diffuse large B-cell lymphoma (DLBCL). A positive interim FDG-PET was shown to be associated with an unfavorable outcome in high-grade

non-Hodgkin’s lymphomas. For positive interim FDG-PET patients, the question of increasing the intensity of treatment using high-dose chemotherapy followed by auto-SCT (HDC-ASCT) remains unanswered. We retrospectively analyzed the prognostic value of FDG-PET in 42 DLBCL patients who were systematically evaluated at time of diagnosis, before and after HDC-ASCT. Of note, HDC-ASCT was part of the initial treatment strategy, while FDG-PET results did not influence the treatment approach. Results and outcome were analyzed according to FDG-PET results before and after HDC-ASCT. Patients were classified into three groups according to FDG-PET results before and after HDC-ASCT: those who were negative before and after (-/-; n = 25), positive before and negative after (+/-; n = 9) or

positive before and after (+/+; n = 8). The median follow-up was 34.5 (range, 19-74) months. The median EFS was significantly Ruboxistaurin cell line lower for the +/+ group (27.4 months) as compared with other groups (median not reached; P = 0.0001). More importantly, there was no difference in term of EFS between the -/-

group compared with the +/- group. These results suggest that HDC-ASCT can significantly improve the bad prognosis, otherwise indicated by a positive interim FDG-PET. Bone Marrow Transplantation (2011) 46, 393-399; doi:10.1038/bmt.2010.130; published online 31 May 2010″
“PURPOSE: This study aimed to evaluate the responsiveness of surgery residents to simulated laparoscopic sigmoidectomy training.\n\nMETHODS: Residents underwent simulated laparoscopic sigmoidectomy training for previously tattooed sigmoid cancer with use of P005091 solubility dmso disposable abdominal trays in a hybrid simulator to perform a seven-step standardized technique. After baseline testing and training, residents were tested with predetermined proficiency criteria. Content validity was defined as the extent to which outcome measures departed from clinical reality. Content-valid measures of trays were evaluated by two blinded raters. Simulator-generated metrics included path length and smoothness of instrument movements. Responsiveness was defined as change in performance over time and was assessed by comparing baseline testing with unmentored final testing.\n\nRESULTS: For eight weeks, eight postgraduate year 3/4 residents performed 34 resections. Overall operating time (67 vs. 37 min; P = 0.005), flexure (10 vs. 5 min; P = 0.
