MADE: A Computational Tool for Predicting Vaccine Effectiveness for the Influenza A(H3N2) Virus Adapted to Embryonated Eggs

open access: yesVaccines, 2022
Seasonal Influenza H3N2 virus poses a great threat to public health, but its vaccine efficacy remains suboptimal. One critical step in influenza vaccine production is the viral passage in embryonated eggs. Recently, the strength of egg passage adaptation

Low 2012-13 influenza vaccine effectiveness associated with mutation in the egg-adapted H3N2 vaccine strain not antigenic drift in circulating viruses. [PDF]

open access: yesPLoS ONE, 2014
Influenza vaccine effectiveness (VE) is generally interpreted in the context of vaccine match/mismatch to circulating strains with evolutionary drift in the latter invoked to explain reduced protection.

Variable Response to Chemotherapeutics by a Subpopulation of MCF-7 Breast Cancer Cells [PDF]

open access: yes, 2016
Several different morphologies can be observed in a population of MCF-7 breast cancer cells, but the typical epithelial morphology vastly predominates. After treatment with the chemotherapeutic doxorubicin, the proportion of abnormal morphologies greatly

Transplacental transmission of field and rescued strains of BTV-2 and BTV-8 in experimentally infected sheep [PDF]

open access: yes, 2013
Transplacental transmission of bluetongue virus has been shown previously for the North European strain of serotype 8 (BTV-8) and for tissue culture or chicken egg-adapted vaccine strains but not for field strains of other serotypes.

Tropism of pandemic 2009 H1N1 influenza A virus

open access: yesFrontiers in Microbiology, 2012
Substitutions at the receptor binding site of the pandemic H1N1 2009 influenza A virus (H1N1pdm) hemagglutinin (HA) gene may be critical in determining whether a virus binds to human or avian receptors.
