Performance evaluation of four surrogate Virus Neutralization Tests (sVNTs) in comparison to the in vivo gold standard test

open access: yesFrontiers in Bioscience-Landmark, 2022
Background: Several commercial surrogate Virus Neutralization Tests (sVNTs) have been developed in the last year. Neutralizing anti-SARS-CoV-2 antibodies through interaction with Spike protein Receptor Binding Domain (S-RBD) can block the virus from ...

THE HOMOZYGOSITY TEST OF NEUTRALITY [PDF]

open access: yesGenetics, 1978
ABSTRACT An earlier paper showed that the homozygosity (of a population or sample) was a good statistic for testing departures from selective neutrality in the direction of heterozygote advantage or disadvantage. It is here shown that homozygosity is also influenced by the presence of deleterious alleles and by other departures from ...

Evaluation of immunogenicity of the 2008-2009 seasonal influenza vaccines by microneutralization test [PDF]

open access: yesKorean Journal of Pediatrics, 2012
PurposeFor evaluating the immunogenicity of an influenza vaccine, the microneutralization (MN) test has a higher sensitivity and specificity as compared to the hemagglutination inhibition (HI) test.

TESTING NEUTRALITY IN SUBDIVIDED POPULATIONS [PDF]

open access: yesGenetics, 1982
ABSTRACT Statistical tests of the neutrality hypothesis that are based on the sampling theory of Ewens (1972) require the assumption of panmixia. It is proposed that for a population comprising numerous local populations with weak gene flow among them, tests based on Ewens' theory can be applied separately to samples from each local ...

The methods for removal of direct oral anticoagulants and heparins to improve the monitoring of hemostasis: a narrative literature review

open access: yesThrombosis Journal, 2023
The assessment of hemostasis is necessary to make suitable decisions on the management of patients with thrombotic disorders. In some clinical situations, for example, during thrombophilia screening, the presence of anticoagulants in sample makes ...

Molecular Classification of Enteroviruses Not Identified by Neutralization Tests

open access: yesEmerging Infectious Diseases, 2002
We isolated six viruses from patients diagnosed with aseptic meningitis or hand, foot, and mouth disease. The cytopathic effect of these viruses on cultured cells was like that of enteroviruses.

Kinetics of Neutralizing Antibodies of COVID-19 Patients Tested Using Clinical D614G, B.1.1.7, and B 1.351 Isolates in Microneutralization Assays

open access: yesViruses, 2021
Increasing evidence suggests that some newly emerged SARS-CoV-2 variants of concern (VoCs) resist neutralization by antibodies elicited by the early-pandemic wild-type virus.

Vero microcultures for adenovirus neutralization tests [PDF]

open access: yesJournal of Clinical Microbiology, 1978
A microculture neutralization test is described for measuring specific antibody levels to the 35 human adenovirus serotypes in Vero cells. The test is read at 5 days by macroscopic observation after staining the uninfected cells with crystal violet.

Sensitive neutralization test for rubella antibody [PDF]

open access: yesJournal of Clinical Microbiology, 1979
A modified rubella virus plaque neutralization test for measuring rubella antibody was developed based on the potentiation of the virus-antibody complex by heterologous anti-immunoglobulin. The test is highly sensitive, yielding titers on the average 50 to 100 times higher than the haemagglutination inhibition test or the conventional plaque ...

International proficiency trial for bovine viral diarrhea virus (BVDV) antibody detection: limitations of milk serology

open access: yesBMC Veterinary Research, 2022
Background Control programs were implemented in several countries against bovine viral diarrhea (BVD), one of the most significant cattle diseases worldwide. Most of the programs rely on serological diagnostics in any phase of the program.
