The arylation of 1-aminoadamantane was successful in the presence of donor phosphine ligand. The amination of o- and m-dibromobenzenes was strongly complicated by formation of diamination products. Conditions ensuring predominant formation of the latter were found. The arylation of 2-aminoadamantane was accompanied by oxidation of the initial amine and reduction of aryl halide.”
“Tuberization in cassava (Manihot esculenta Crantz) occurs simultaneously with plant development, suggesting competition check details of photoassimilate partitioning between the shoot and the root organs. In potato, which is the most widely studied tuber crop, there is ample evidence suggesting that metabolism and regulatory processes in leaf
may have an impact on tuber formation. To search for leaf proteins putatively involved in regulating tuber generation and/or development in cassava, comparative proteomic approaches have been applied to monitor differentially expressed leaf proteins during root transition from fibrous to tuberous. Stringent cross comparison and statistical analysis between two groups with different plant ages using Student’s t test with 95% significance level revealed a number of protein spots whose abundance were significantly altered (P Selleckchem AZD8055 < 0.05) during week 4 to week 8 of growth. Of these, 39 spots were successfully identified by ion trap LC-MS/MS. The proteins span various functional categories from antioxidant and defense, carbohydrate
metabolism, cyanogenesis, energy metabolism, miscellaneous and unknown proteins. Results suggested possible metabolic switches in the leaf that may trigger/regulate storage root initiation and growth. This study provides a basis for further functional characterization of differentially expressed leaf proteins, which can help understand how biochemical processes in Stattic purchase cassava leaves may be involved in storage root development.”
“Aim. – The aim of this retrospective study was to evaluate the use and appropriateness of preventive measures for venous thrombosis among adult inpatients in
a Benin teaching hospital.\n\nPatients and methods. – All patients were systematically enrolled. The risk of venous thrombosis was estimated according to international guidelines. Thromboembolic events were diagnosed using the Wells score and, when possible, by paraclinical investigations. The following variables were studied: the risk of venous thrombosis, the use and appropriateness of preventive measures, and the frequency of thromboembolic events. The data were analyzed with Epiinfo 6.04.fr and SPSS software, and significance was assumed at p=0.05.\n\nResults. – The study population consisted of 487 patients recruited in four surgical wards, four general wards and one obstetric-gynecology ward. Mean age was 38.7 +/- 11.3 years and the sex ratio 0.51. The risk of thrombosis was considered low in 15% of patients, moderate in 60.8%, high in 21.1% and very high in 3.
