Sialyltransferases catalyze reactions that transfer a sialic acid from CMP-sialic acid to an acceptor (a structure terminated with galactose, N-acetylgalactosamine, or sialic acid). They are key enzymes that catalyze the synthesis of sialic acid-containing oligosaccharides, polysaccharides, and glycoconjugates that play pivotal roles in many critical physiological and pathological processes. Th...

Chemical Mechanical Polishing (CMP) is currently being used in the fabrication of state-of-the-art integrated circuits, and has been identified as an enabling technology for the semiconductor industry in its drive toward gigabit chips and sub-130nm feature sizes. In this project we present the application of a library-based specular spectroscopic scatterometry method, which is capable of gettin...

BACKGROUND Angiogenesis has a key role in several conditions and is regulated by several factors such as the platelet-derived growth factor (PDGF) or the vascular endothelial growth factor (VEGF). The goal of this study was to investigate the possible role of PDGF and VEGF in a group of patients with severe food allergy. METHODS We design a prospective longitudinal study (n = 30) with patient...

If a component in binary system fails, preventive maintenance (PM) on other components may be conducted while the failed is being repaired. This raises question which should selected for PM if resource limited. The can answered by using priority (CMP) to prioritise PM. paper extends definition of CMP cases multi-state systems, continuum systems and non-coherent respectively. It investigates app...

The long time series of estimated party policy positions generated by the Comparative Manifesto Project (CMP) is the only such time series available to the profession and has been extensively used in a wide variety of applications. Recent work (e.g. Benoit, Laver, and Mikhaylov 2007; Klingemann et. al. 2006, chs. 4–5) focuses on non-systematic sources of error in these estimates that arise from...

The microelectronics industry is focused on increasing chip complexity, improving the density of electron carriers, and decreasing the dimensions of the interconnects into the sub-0.25 mum regime while maintaining high aspect ratios. Water-based chemical mechanical planarization or polishing (CMP) faces several technical and environmental challenges. Condensed CO2 has significant potential for ...

Lipoxygenases have been proposed to be a possible factor that is responsible for the pathology of certain diseases, including ischaemic injury. In the peroxidation process of linoleic acid by lipoxygenase, the E,Z-linoleate allyl radical-lipoxygenase complex seems to be generated as an intermediate. In the present study, we evaluated whether E,Z-linoleate allyl radicals on the enzyme are scaven...

cooling towers are widely used in most industrial units to reject waste heat to the atmosphere. this paper deals with an experimental analysis of heat and mass transfer phenomena between water and air by direct contact in a cooling tower. the tower is filled with 6 type packing. in this study temperature and pressure drop and tower characteristics was used in determining experimentally the ther...

Three C terminal His6-tagged recombinant microbial CMP-sialic acid synthetases [EC 2.7.7.43] cloned from Neisseria meningitidis group B, Streptococcus agalactiae serotype V, and Escherichia coli K1, respectively, were evaluated for their ability in the synthesis of CMP-sialic acid derivatives in a one-pot two-enzyme system. In this system, N-acetylmannosamine or mannose analogs were condensed w...
