Very similar structures are obtained when the organic cation is NMe4+, NMe2Pr2+, or NMe2Bu2+. A distorted anionic structure possessing the same connectivity is generated when the cation is NEt4+, and anionic frameworks with a different connectivity, but still related to

PtS, are obtained when the much larger quaternary phosphonium cations are employed. Of interest in the structures containing quaternary phosphonium cations are pi-stacking interactions involving phenyl groups of the cation and F(4)TCNQ(2-) ligands. These face-to-face interactions between the electron-rich F(4)TCNQ(2-) ligands and a Selleck AZD6094 phenyl group of the cation appear to be responsible for the color exhibited by these compounds.”
“Aim:\n\nThis study was undertaken to determine if the need for red cell blood transfusion in placenta praevia could be predicted.\n\nMethods:\n\nData from a retrospective observational study of 246 obstetric patients, with placenta praevia, from 1999 to 2005 were analysed to generate a model to predict requirement for transfusion.\n\nResults:\n\nSeventy-one

patients were transfused. Independent risk factors for transfusion were gestational age at delivery of 32-35 weeks [odds ratio (OR): 2.6; 95% confidence interval (CI): 1.1-6.4] and caesarean combined with hysterectomy (OR: 29.4; 95% CI: 5.9-145.9; P < 0.001). No independent risk of transfusion was associated with

maternal age, race, learn more INCB024360 concentration parity, smoking status, type of anaesthesia, caesarean combined with arterial balloon occlusion, grade of placenta, accreta and previous uterine surgery.\n\nConclusions:\n\nGestational age at delivery and type of surgery required are predictors of transfusion during caesarean for placenta praevia. Arterial balloon occlusion does not appear to increase transfusion risk and may be considered as one of the techniques in management.”
“Aim: To evaluate the relationship between epidermal growth factor receptor (EGFR) mutations and serum carcinoembryonic antigen (CEA) levels in Chinese nonsmokers with pulmonary adenocarcinoma. Methods: We sequenced exons 18-21 of the EGFR gene in 98 cases. The patients were divided into two groups based on their pretreatment serum CEA levels (below or above 5 ng/mL) for analyzing the correlations with EGFR mutations. Results: Sixty-seven cases harbored EGFR mutations. The rates of EGFR mutations and exon 19 mutations in the high-CEA group (78.2% and 49.1%, respectively) were significantly higher than those in the low-CEA group (55.8% and 20.9%, respectively). Serum CEA levels were found to be the only independent predictor of EGFR mutation (OR 2.837; 95% CI: 1.178-6.829) and exon 19 mutation (OR 3.618; 95% CI: 1.319-9.918).
