2981   Catalytic Carboalumination of Olefins with Cyclopentadienylamidotitanium Dichloride Complexes Catalytic Carboalumination of Olefins with Cyclopentadienylamidotitanium Dichloride Complexes Dan B. Millward, Adam P. Cole, and Robert M. Waymouth*    2000 The half-sandwich metallocene η5-(C5Me4)SiMe2N(tBu)TiCl2 reacts with a stoichiometric amount of dibutylmagnesium in tetrahydrofuran to form. a robust monobutyl monochloride η5-(C5Me4)SiMe2N(tBu)Ti(Bu)Cl. X-ray crystallography reveals an undistorted η1-butyl ligand. In the presence of an excess of triethylaluminum the dichloride η5-(C5Me4)SiMe2N(tBu)TiCl2 serves as a catalyst for the carboalumination of olefins. The organometallic products of these reactions can be oxidized to 1,4-butanediols... 查看全文

2989   Successful hepatectomy for intraperitoneal rupture of pyogenic liver abscess caused by Klebsiella pneumoniae Successful hepatectomy for intraperitoneal rupture of pyogenic liver abscess caused by Klebsiella pneumoniae Kazuhiko Morii, Asako Kashihara, Sho Miura, Hiroaki Okuhin, Takanori Watanabe, Shiso Sato, Koichi Ue    2012 Klebsiella pneumoniae (KP) is the most common cause of pyogenic liver abscess in eastern Asia. KP liver abscess commonly presents as a single large abscess with a predominantly solid consistency. It is sometimes unsuitable for percutaneous catheter drainage because of the poorly liquefied contents. Antibiotic therapy alone may raise a probability of treatment failure and occurrence of complications such as abscess rupture. Hepatic or portal venous thrombosis, hem... 查看全文

2991   Unexpected Electrophoretic Migration of RNA with Different 3‘ Termini Causes a RNA Sizing Ambiguity That Can Be Resolved Using Nuclease P1-Generated Sequencing Ladders† Unexpected Electrophoretic Migration of RNA with Different 3‘ Termini Causes a RNA Sizing Ambiguity That Can Be Resolved Using Nuclease P1-Generated Sequencing Ladders† Jorge Cruz-Reyes, Kenneth J. Piller, Laura N. Rusché, Mita Mukherjee, and Barbara Sollner-Webb*    1998 It has been widely believed that the electrophoretic migration difference of otherwise identical RNAs with a P versus OH terminus would be the same as occurs for DNA, a fairly reproducible 1/2 nucleotide (nt) offset. RNA with a 5‘-OH indeed migrates ≤1 nt slower than if it had a 5‘-P. Surprisingly, however, RNA with a 3‘-OH terminus (generated by many cellular RNases of interest) migrates anywhere from 1/4 to 2 nts slower than the otherwise identical molecule with a 3‘-P or 2‘,3‘-cyclic-P termin 查看全文

2997   The native structure protects SUMO proteins from aggregation into amyloid fibrils The native structure protects SUMO proteins from aggregation into amyloid fibrils Raimon Sabaté, Alba Espargaro, Ricardo Graña-Montes, David Reverter, and Salvador Ventura    2012 SUMO proteins belong to the Ubiquitin-like protein family, all sharing a common fold and a similar mechanism of conjugation to target polypeptides. SUMO is ubiquitous in all eukaryotes and participates in many crucial pathways. Native SUMO proteins are highly soluble, a property that is exploited in biotechnology. Moreover, SUMO regulates the solubility of aggregation-prone proteins in neurodegenerative disorders. Despite these properties, we show here that human SUMO1, SUMO2 and SUMO3 proteins ... 查看全文

SOME ASPECTS OF THE STATISTICAL MODELING OF PARTIAL DISCHARGE INCEPTION CONDITIONS.    1988 Statistical modeling procedures are presented for representing various conditions in different types of samples and equipment at, or near, the onset of partial discharge (PD). Using multiple-regression techniques it was possible to establish trends in PD behavior. in terms of the repetition rate. The latter parameter was chosen as being sensitive to changes near inception, and it is measurable by conventional instrumentation. The statistical repetition rate models also can be related to the prob... 查看全文

3005   Vascular endothelial growth factor corrected for platelet count and hematocrit is associated with the clinical course of aplastic anemia in children Vascular endothelial growth factor corrected for platelet count and hematocrit is associated with the clinical course of aplastic anemia in children Yuichi Kodama, Yasuhiro Okamoto, Teruto Hashiguchi, Yuichi Shinkoda, Takuro Nishikawa, Takayuki Tana    2012 The wide variety of clinical courses that lead to the development of severe aplastic anemia (AA) makes it difficult to speculate whether treatment for AA is required in the early phase. The objective of this study was to identify a method for predicting the clinical course of AA at the onset of the disease. First, in healthy adults, vascular endothelial growth factor (VEGF) released per platelet was measured by the activation of platelet-rich plasma (PRP) and pla... 查看全文

3006   Seismic risk assessment of spatially-distributed systems using ground-motion models fitted considering spatial correlation Seismic risk assessment of spatially-distributed systems using ground-motion models fitted considering spatial correlation    2011 Ground-motion models are commonly used in earthquake engineering to predict the probability distribution of the ground-motion intensity at a given site due to a particular earthquake event. These models are often built using regression on observed ground-motion intensities, and are fitted using either the one-stage mixed-effects regression algorithm proposed by Abrahamson and Youngs (1992) or the two-stage algorithm of Joyner and Boore (1993). In their current forms, these algorithms ignore the ... 查看全文
