The P protein is phosphorylated at multiple sites, probably by more than one host kinase. While it is thought that the phosphorylation of P is important for its role in viral RNA synthesis,

the precise role of P protein phosphorylation remains an enigma. For instance, it was demonstrated that the putative CKII phosphorylation sites of the P protein of respiratory syncytial virus play a role in viral RNA synthesis using a minigenome replicon system, however, mutating these putative CKII phosphorylation sites within a viral genome had no effect on viral RNA synthesis, leading to the hypothesis LY2603618 Cell Cycle inhibitor that P protein phosphorylation, at least by CKII, does not play a role in viral RNA synthesis. Recently, it has been reported that the phosphorylation state of the P protein of parainfluenza virus 5, a prototypical poramyxovirus, correlates with the ability of P protein to synthesize viral RNA, indicating that P protein phosphorylation does in fact play a role in viral RNA synthesis. Furthermore, host kinases PLK1, as well as AKT1 have been found to play critical

roles in paramyxovirus RNA synthesis through regulation of P protein phosphorylation status. Beyond furthering our understanding of paramyxovirus RNA replication, these recent discoveries may also result in a new paradigm in treating infections caused by these viruses, as host kinases that regulate paramyxovirus replication are investigated as potential selleck inhibitor targets of therapeutic intervention.”
“Miniemulsion polymerization is a powerful technique to produce a whole variety of latexes with controlled colloidal and chemical properties, which has gained an increasing importance in the past years. For many applications, the following of the kinetics of polymerization is of crucial importance. In this study, we developed

a technique based on the use of fluorescent probes that could be a very promising noninvasive method to follow the reaction in situ. It was possible to follow qualitatively the kinetics of methyl methacrylate (MMA) polymerization by measuring the photophysical properties of fluorescent probes sensitive to the modification of the viscosity of the microenvironment along the reaction course. Two fluorescent sensors have been considered: 1,1-dicyano-4-(4′-dimethylaminophenyl)-1,3-butadiene) and pyrene. In HM781-36B mouse this article, we will show that using these two different fluorescent probes allow the detection of MMA polymerization in miniemulsion. The results will be compared with a classical NMR method. This method could be easily adapted to different monomers. (C) 2010 Wiley Periodicals, Inc. J Appl Polym Sci 119: 219-224, 2011″
“P>To identify loci in Arabidopsis involved in the control of transpirational water loss and transpiration efficiency (TE) we carried out an infrared thermal imaging-based screen. We report the identification of a new allele of the Arabidopsis CesA7 cellulose synthase locus designated AtCesA7irx3-5 involved in the control of TE.
