The purpose of this study was to analyze the effects of cadmium toxicity on rat embryogenesis when exposed to other heavy metal citrates. Despite the variety of scientific publications discussing the influence of cadmium on mammalian postnatal development, the effect of this metal on embryogenesis has not yet been sufficiently studied. In this experimental study, cadmium chloride was administered to experimental pregnant female Wistar rats at a daily dose of 1.

Article Synopsis
  • The decline in mass smallpox vaccination since 1980 has led to a significant reduction in human immunity against orthopoxvirus infections, raising the risks of zoonotic diseases like monkeypox and cowpox.
  • Traditional smallpox vaccines are not suitable for mass use due to their reactogenicity, prompting the need for modern live vaccines using genetic engineering techniques.
  • Researchers developed the VACΔ6 strain by deleting virulence genes and conducting extensive passaging, ensuring minimal off-target mutations, and performing genomic stability tests to confirm its potential as a safe vaccine candidate.

Mass vaccination has played a critical role in the global eradication of smallpox. Various vaccinia virus (VACV) strains, whose origin has not been clearly documented in most cases, have been used as live vaccines in different countries. These VACV strains differed in pathogenicity towards various laboratory animals and in reactogenicity exhibited upon vaccination of humans.

The modern approach to developing attenuated smallpox vaccines usually consists in targeted inactivation of vaccinia virus (VACV) virulence genes. In this work, we studied how an elevated production of extracellular enveloped virions (EEVs) and the route of mouse infection can influence the virulence and immunogenicity of VACV. The research subject was the LIVP strain, which is used in Russia for smallpox vaccination.

Introduction: Currently, new directions in cancer therapy are actively developing, one of which is oncolytic immunotherapy. This approach would be to use of viruses as cancer specific cytolytic agents capable of stimulating both the tumor-specific and non-specific immune response. The objective paper was obtain a recombinant vaccinia virus containing genes encoding immunostimulating molecules and study oncolytic and immunostimulating properties of recombinant virus.
