A multicenter retrospective analysis was performed to estimate the frequency of thrombosis and hemorrhage after surgical procedures in patients with polycythemia vera (PV) and patients with essential thrombocythemia (ET). Data from 105 patients with PV and 150 patients with ET were analyzed, for a total of 311 surgical interventions. An emergency procedure was performed in 25 (8.1%) patients; 1...
the intermolecular forces between water molecules are of great importance in many areas of chemistry including solvation, solution chemistry, and biochemistry. as a result of this (h2o)n systems have received a great significant of attention, both experimental and theoretical. all calculation of this study are carried out by gaussian 98 soft ware. geometry optimization for each cluster were be ...

The eect of sample thickness on the nucleation, growth and dissolution of {311} defects in non-amorphizing 100 keV, 2 10 cmÿ2 Si implanted Si has been investigated by plan-view transmission electron microscopy (PTEM) and cross-section TEM (XTEM). The samples were annealed at 8008C for times between 5 and 30 min. Results from samples annealed prior to TEM sample preparation were compared with s...
The evolution of both $311% defects and dislocation loops in the end-of-range ~EOR! damage region in silicon amorphized by ion implantation was studied by ex situ transmission electron microscopy ~TEM!. The amorphization of a ~100! n-type Czochralski wafer was achieved with a 20 keV 1310/cm Si ion implantation. The post-implantation anneals were performed in a furnace at 750 °C for times rangin...
High level correlated quantum chemical calculations, using MP2 and local MP2 theory, have been performed for conformations of the disaccharide, beta-maltose, and the trisaccharide, 3,6-di-O-(alpha-D-mannopyranosyl)-alpha-D-mannopyranose. For beta-maltose, MP2 and local MP2 calculations using the 6-311++G** basis set are in good agreement, predicting a global minimum gas-phase conformation with ...
Although chronic Pseudomonas aeruginosa infection is the major cause of morbidity and mortality in cystic fibrosis (CF) patients, there is no approved vaccine for human use against P. aeruginosa. The goal of this study was to establish whether a multivalent vaccine containing P. aeruginosa type A and B flagellins as well as the outer membrane proteins OprF and OprI would promote enhanced cleara...
Enaminones are those structures made up three various functional groups including carbonyl, alkeneand amine groups which arelocated along with each other in a conjugate fashion. These compoundsare of much attention due to special characteristics and numerous applications. In the paper, sixvarious enaminone structures were theoretically optimized and after concluding, were compared withequivalen...
