In a short time, West Nile virus has developed into a nationwide health and veterinary problem. The high virulence of the circulating virus and related lineage 1 WN strains hinders development of an attenuated live vaccine. We describe an attenuated WN isolate, WN1415, which is a molecularly cloned descendant of the WN prototype B956 strain. The parent(More)
Recently, we have described a lineage 2 attenuated WN virus suitable for the development of a live WN vaccine. To design vaccine candidates with an improved immunogenicity, we assembled an infectious clone of the NY99 strain and created several chimeric constructs with reciprocal exchanges of structural protein genes between attenuated W956 and virulent(More)
Injection of Na+ or Li+ into cortical glia evokes glial depolarization, discharge of adjacent neurons, and vascular pulsation. The effects can be explained by the extrusion of K+ from glia after cation injection, glial swelling, and the slow removal of the cation from glia. The data suggest that the reduced rate of reuptake of K+ into Na+-loaded glia(More)
Seven volunteers involved in flavivirus studies have been immunized with commercial Japanese encephalitis and yellow fever vaccines JE-VAX and YF-VAX. Strong homologous and cross-reactive with West Nile virus (WNV) antibody responses with titers 1:1600 to 1:51200 were found in all donors. All donors developed high levels of yellow fever virus (YFV) and(More)
The exceptionally high virulence of the West Nile NY99 strain makes its suitability in the development of a live WN vaccine uncertain. The aim of this study is to investigate the immunogenicity of noninfectious virus derivatives carrying pseudolethal mutations, which preclude virion formation without affecting preceding steps of the viral infectious cycle.(More)
In recent years, there has been increasing interest of researchers in new methods of control of pathogenic microorganisms. This was due to a significant increase in the number of strains resistant to conventional antimicrobial preparations [1, 2]. Photodynamic therapy (PDT) is one of these new methodological approaches. PDT includes a combination of three(More)

This paper presents the results of a comprehensive analysis of structural changes in the caudal vertebrae of Turner's thick-toed geckos by computer microtomography and X-ray fluorescence analysis. We present algorithms used for the reconstruction of tomographic images which allow to work with high noise level projections that represent typical conditions(More)
