Trinuclear ReFePt clusters with a μ-phenylvinylidene ligand: synthetic approaches, rearrangement of vinylidene, and redox-induced transformations.

A series of trinuclear μ-vinylidene ReFePt clusters were synthesized by the application of two approaches: (i) reactions of the binuclear RePt μ-vinylidene complexes with Fe(CO); (ii) ligand substitution or exchange reactions at the Pt atom in the synthesized ReFePt clusters. The molecular structures of CpReFePt(μ-CCHPh)(CO)[P(OEt)]L [L = CO; P(OEt)] were determined by an X-ray diffraction study. The obtained compounds were studied by IR and H, C and P NMR spectroscopy.

Identification of T-cell epitopes in African swine fever virus CD2v and C-type lectin proteins.

African swine fever (ASF) is an emerging disease threat for the swine industry worldwide. No ASF vaccine is available, and progress is hindered by lack of knowledge concerning the extent of ASF virus (ASFV) strain diversity and the viral antigens conferring type-specific protective immunity in pigs. Previously, we demonstrated that ASFV serotype-specific proteins CD2v (EP402R) and/or C-type lectin (EP153R) are important for protection against homologous ASF infection.

Real-time analysis of the cytopathic effect of African swine fever virus.

Conventional methods, which quantitatively assess virus replication, are based on direct examination of viral cytopathic effect (CPE), which is time consuming, tedious and based on endpoint reading. The Real-Time Cell Analysis (RTCA) xCELLigence® system offers an alternative approach to evaluate virus-induced CPE, and here was evaluated as a means to dynamically assess CPE caused by African swine fever virus (ASFV). RTCA was used to identify optimum time for ASFV infection based on cell index (CI) and to evaluate ASFV CPE kinetics in COS-1 cells.

Proposal for a unified classification system and nomenclature of lagoviruses.

Lagoviruses belong to the Caliciviridae family. They were first recognized as highly pathogenic viruses of the European rabbit (Oryctolagus cuniculus) and European brown hare (Lepus europaeus) that emerged in the 1970-1980s, namely, rabbit haemorrhagic disease virus (RHDV) and European brown hare syndrome virus (EBHSV), according to the host species from which they had been first detected. However, the diversity of lagoviruses has recently expanded to include new related viruses with varying pathogenicity, geographic distribution and host ranges.
