Immuno-Colorimetric Neutralization Test: A Surrogate for Widely Used Plaque Reduction Neutralization Tests in Public Health Virology. [PDF]

open access: yesViruses, 2023
Since their first documentation in 1952, plaque reduction neutralization tests (PRNTs) have become the choice of test for the measurement of neutralizing antibodies against a particular virus.

Evaluation of Two Serological Assays for Diagnosing Zika Virus Infection

open access: yesDiagnostics, 2021
Zika virus (ZIKV) emerged and spread rapidly in South American countries during 2015. Efforts to diagnose ZIKV infection using serological tools were challenging in dengue-endemic areas because of antigenic similarities between both viruses.

Classification of genotypes based on the VP1 gene of feline calicivirus and study of cross-protection between different genotypes

open access: yesFrontiers in Microbiology, 2023
Feline calicivirus (FCV) causes upper respiratory tract diseases and even death in cats, thereby acting as a great threat to feline animals. Currently, FCV prevention is mainly achieved through vaccination, but the effectiveness of vaccination is limited.

TESTING κ-POINCARÉ WITH NEUTRAL KAONS [PDF]

open access: yesModern Physics Letters A, 2000
In recent work on experimental tests of quantum-gravity-motivated phenomenological models, a significant role has been played by the so-called "κ" deformations of Poincaré symmetries. Sensitivity to values of the relevant deformation length λ as small as 5×10-33 m has been achieved in recent analyses comparing the structure of κ-Poincaré symmetries ...
