Removal of small non‐enveloped viruses by nanofiltration
Vox Sanguinis, 2004Background and Objectives Nanofiltration is one of the most effective virus reduction methods in the manufacturing process of plasma products. However, it is difficult to remove small viruses from high molecular weight protein preparations like immunoglobulin G or factor VIII complex by nanofiltration, because the size of the protein is similar to ...

Natural Plant Essential Oils Do Not Inactivate Non-enveloped Enteric Viruses
Food and Environmental Virology, 2012The application of plant essential oils (EOs) (hyssop and marjoram) was evaluated for inactivation of non-enveloped viruses using murine norovirus and human adenovirus as models. No significant reduction of virus titres (TCID(50)) was observed when EOs were used at different temperatures and times.

Intra-family differences in efficacy of inactivation of small, non-enveloped viruses
Biologicals, 2016The use of specific model viruses for validating viral purification process steps and for assessing the efficacies of viral disinfectants is based, in part, on the assumption that viral susceptibilities to such treatments will be similar for different members, including different genera, within a given viral family.

Membrane Components Interacting with Non-enveloped Viruses
1981Historically, two divergent views have evolved about the specificity of animal virus attachment to susceptible host cells. One emphasizes the absence of precise structural requirements for virus-cell interaction (Dales, 1973) and the second proposes specific cellular receptor sites in the plasma membrane which recognizes one or several of the virus ...

Susceptibility of non-enveloped DNA- and RNA-type viruses to photodynamic inactivation
Photochemical & Photobiological Sciences, 2012The comparative susceptibility of DNA- and RNA-type viruses to photodynamic inactivation has not yet been clearly addressed. In this study the effect of the tricationic porphyrin Tri-Py(+)-Me-PF on the inactivation of four DNA and three RNA non-enveloped phages was compared.

Old foes, new understandings: nuclear entry of small non-enveloped DNA viruses
Current Opinion in Virology, 2015The nuclear import of viral genomes is an important step of the infectious cycle for viruses that replicate in the nucleus of their host cells. Although most viruses use the cellular nuclear import machinery or some components of this machinery, others have developed sophisticated ways to reach the nucleus.

Components of Non-enveloped Viruses which Recognize Receptors
1981Non-enveloped animal viruses, in most cases, have icosahedral symmetry. Therefore, they have at least 12 identical sites for interaction with receptors on host cells. The multiple subunit structure of the virion capsid leads not only to multivalent receptor bonding, but may also confer allosteric properties to the virion.

Virucidal activity of hypericin against enveloped and non-enveloped DNA and RNA viruses
Antiviral Research, 1990Hypericin is a polycyclic anthrone first isolated from the plant St. Johnswort and was shown to have dramatic anti-retroviral activity against Friend leukemia virus and radiation leukemia virus in mice. Hypericin displayed marginal activity (IC50 = 6 micrograms/ml) against Moloney murine leukemia virus (Mo-MuLV) in vitro.

Recent advances in the structure and assembly of non-enveloped spherical viruses
VirologyNon-enveloped spherical viruses (NSVs) are characterized by their highly symmetrical capsids that serve to protect and encapsulate the genomes. The stability and functionality of the capsids determine their ability for survival and proliferation in harsh environments.

Technology and Health Care, 2016
BACKGROUND: As obligate intracellular parasites, all viruses penetrate target cells to initiate replication and infection. OBJECTIVE: This study introduces two approaches for evaluating the contact loads applied to a cell during early penetration of non-enveloped icosahedral viruses.
