ESR and NMR studies provide evidence that phosphatidyl glycerol specifically interacts with poxvirus membranes

Virology Journal, 2010
Background The lung would be the first organ targeted in case of the use of Variola virus (the causative agent of smallpox) as a bioweapon. Pulmonary surfactant composed of lipids (90%) and proteins (10%) is considered the major physiological barrier ...

Immunological Memory after Exposure to Variola Virus, Monkeypox Virus, and Vaccinia Virus [PDF]

The Journal of Infectious Diseases, 2007
We compared cellular and humoral immunity to vaccinia virus (VV) in individuals exposed to 3 different orthopoxviruses: 154 individuals previously vaccinated with VV, 7 individuals with a history of monkeypox virus infection, and 8 individuals with a history of variola virus infection.

Terminal Region Sequence Variations in Variola Virus DNA

Virology, 1996
Genome DNA terminal region sequences were determined for a Brazilian alastrim variola minor virus strain Garcia-1966 that was associated with an 0.8% case-fatality rate and African smallpox strains Congo-1970 and Somalia-1977 associated with variola major (9.6%) and minor (0.4%) mortality rates, respectively.

Engineered Nile Red Derivatives‐Mediated Efficient Phototherapy Against Drug‐Resistant Bacteria and Monkeypox Virus

Aggregate, EarlyView.
TPAOMCN exhibits optimal reactive oxygen species (ROS) generation and photothermal conversion properties. TPAOMCN nanofibers (NFs)‐mediated photodynamic (PDT) and photothermal therapy (PTT) achieved efficient eradication against multidrug‐resistant bacteria and viruses, alleviating inflammation response, promoting wound healing, and providing a ...

Silica Nanoparticles as Multifunctional Platforms for Vaccine Delivery and Immune Modulation in Infectious Diseases

Advanced NanoBiomed Research, EarlyView.
Overview of the use of silica nanoparticles in vaccines against pathogens. Different kinds of vaccines against infectious diseases are currently using solid or mesoporous silica nanoparticles in their formulation. Silica microparticles and nanoparticles (SiNPs) have been studied as vehicles for vaccines.

Harvesting AAV by tangential flow filtration using reverse asymmetric membranes

Biotechnology Progress, EarlyView.
Abstract Efficient bioreactor clarification for harvesting virus particles is often challenging. Tangential flow filtration is attractive as it can be easily adapted for batch and perfusion operations. Here the feasibility of using reverse asymmetric hollow fiber membranes, where the more open support structure faces the feed stream, has been ...
