Abstract OR-7: Genome Release Mechanism of Picorna-Like Viruses

Protein capsids protect the genomes of viruses from degradation in the extracellular environment. However, virus capsids must release genomes into a host cell to initiate infection. We used cryo-electron microscopy to characterize the genome release of viruses from the order Picornavirales: picornaviruses, dicistroviruses, and iflaviruses. These virus families include numerous human and animal pathogens. The viruses have non-enveloped virions and capsids organized with icosahedral symmetry. Their genome release can be induced in vitro by exposure to acidic pH, mimicking conditions in endosomes. We show that conformational changes of capsids and expansion of viral RNA genomes, which are induced by acidic pH, trigger the opening of picorna-like virus particles. The capsids of the studied viruses crack into pieces or open like flowers to release their genomes. The large openings of capsids enable the virus genomes to exit within microseconds, which limits the probability of their degradation by the RNases. Characterization of the virus genome release is the first step towards developing inhibitors of the process

The Design for the Reconstruction of Settling Tanks

This article describes the design of the reconstruction of the mechanical and technological equipment of the settling tanks at the wastewater treatment plant in the municipality of Boskovice. The reconstruction was focused on the flocculation cylinder, the travelling bridge, the bridge drive, and the collection of the settling tank floating sludge

New targeting system for antimycotic drugs: beta-Glucosidase sensitive Amphotericin B-star poly(ethylene glycol) conjugate

A new targeting potentially intravenous conjugate Amphotericin B (AMB)-star poly(ethylene glycol) (sPEG) (M = 25,160) has been synthesized and characterized. It contains a beta-D-glucopyranoside molecular switch which is sensitive to beta-glucosidases (E. C. 3.2.1.21). The beta-glucosidase-catalyzed release of AMB from the polymeric carrier was proved in vitro by means of spectrophotometry and HPLC. (C) 2008 Elsevier Ltd. All rights reserved
