Template Activity of Parainfluenza Virus Ribonucleoprotein

Nature, 1970
WE have shown previously that Sendai virus ribonucleoprotein (RNP) particles in the cytoplasm of infected cells are associated with ribosomes in complexes of buoyant density δ = 1.45 g cm−3, and that these take up labelled amino-acids1,2. We now demonstrate that Sendai virus RNP stimulates the incorporation of labelled amino-acids into polypeptides in ...

Anti-influenza virus activity of biflavonoids

Bioorganic & Medicinal Chemistry Letters, 2007
Ginkgetin was found to inhibit the influenza virus sialidase. Ginkgetin-sialic acid conjugates showed a significant survival effect in the influenza-virus-infected mice.

Virus-binding activity of fibronectin: Masking of hepatitis A virus

Journal of Virological Methods, 1984
Human plasma fibronectin interacts with viruses. When fibronectin-containing human sera negative for antibodies to hepatitis A virus (HAV) were added to suspensions of HAV, radioimmunological detection of HAV was reduced. This masking effect seemed to depend on the fibronectin concentration of the sera: plasma fibronectin purified by cryoprecipitation ...

Biological Activity of Tumor Virus Dna

1977
Publisher Summary This chapter deals with recent studies on the biological activity of viral DNA, with emphasis on the studies dealing with cell transformation. It describes commonly used techniques for assaying biological activity of purified viral DNA and discusses the development of these assays and their mechanism of action.

Immunity to Herpes Simplex Virus: Virus Reactivation Modulates Lymphokine Activity

Journal of Infectious Diseases, 1985
Cell-mediated immunity to herpes simplex virus (HSV) was studied in patients with recurrent disease and in seropositive controls. Supernatants from cultures of peripheral blood mononuclear cells (PBLs) obtained during recrudescence (zero to three days after onset of lesions), convalescence (four to 14 days), and quiescence (greater than 14 days) were ...

Activation of Phospholipase Activity during Semliki Forest Virus Infection

Virology, 1993
Infection of animal cells by a number of cytolytic viruses leads to increased membrane permeability. Thus, Semliki Forest virus (SFV) infection of susceptible cells modifies the permeability of the membrane for a number of cations and metabolites (Muñoz et al. (1985), Virology 146, 203-212). The molecular basis of this modification of the cell membrane

Virus Entry and Innate Immune Activation

2008
Human cytomegalovirus (HCMV) exhibits an exceptionally broad cellular tropism as it is capable of infecting most major organ systems and cell types. Definitive proof of an essential role for a cellular molecule that serves as an entry receptor has proven very challenging.

'Chronic Active Epstein-Barr Virus Infection'

JAMA: The Journal of the American Medical Association, 1987
To the Editor.— I was surprised by the approach taken by Buchwald et al 1 in their recent study of what they term chronic active Epstein-Barr virus (EBV) infection . The authors defined their study group solely on the basis of self-reporting of symptoms by patients.

Heat activation of plant virus infections

Virology, 1961
Abstract When bean or cowpea leaves were inoculated with certain viruses and, within 8 seconds after mechanical inoculation, held in water or mercury for 0.5-4 seconds at 45–65°, the number of resulting lesions were increased. As the interval from inoculation to heating was increased beyond 10 seconds, heat activation decreased and heat inactivation ...

Active virus filter for enrichment and manipulation of virus

2011 IEEE 24th International Conference on Micro Electro Mechanical Systems, 2011
We developed an active virus filter (AVF) that was able to virus enrichment and distribution for single virus manipulation by using the insulator based dielectrophoresis (iDEP). The design of constricted flow channel enabled the microfluidic chip to produce iDEP force.
