Evolution of H5N1 Cross‐Species Transmission: Adaptive Mutations Driving Avian‐to‐Human Infection

Advanced Genetics, Volume 7, Issue 1, March 2026.
This review synthesizes current knowledge on the molecular mechanisms underpinning H5N1's host adaptation, focusing on key mutations in viral proteins. Critical mutations are discussed in detail, highlighting their roles in altering receptor specificity, promoting antiviral resistance, and expanding viral tropism. The review underscores the urgent need

Transplacental Chikungunya Virus Antibody Kinetics, Thailand

Emerging Infectious Diseases, 2006
Antibodies to chikungunya virus were detected by hemagglutination-inhibition assay in 33.6% of 2,000 infants' cord sera at delivery. Follow-up of 24 seropositive infants showed that the half-life of antibody persistence was 35.5 days.

c-di-GMP modulates type IV MSHA pilus retraction and surface attachment in Vibrio cholerae. [PDF]

, 2020
Biofilm formation by Vibrio cholerae facilitates environmental persistence, and hyperinfectivity within the host. Biofilm formation is regulated by 3',5'-cyclic diguanylate (c-di-GMP) and requires production of the type IV mannose-sensitive hemagglutinin

Cross-protection between antigenically distinct H1N1 swine influenza viruses from Europe and North America [PDF]

, 2011
Background An avian-like H1N1 swine influenza virus (SIV) is enzootic in swine populations of Western Europe. The virus is antigenically distinct from H1N1 SIVs in North America that have a classical swine virus-lineage H1 hemagglutinin, as does the ...

The Americanization of Nigerian English spelling and punctuation

World Englishes, Volume 45, Issue 1, Page 76-95, March 2026.
Abstract Spelling is the most standardized level of language, and prescriptive spelling norms in former British colonies often advocate adherence to British spelling norms which differs from the local linguistic reality. Hence, recent research on the evolution of postcolonial Englishes and the Americanization of Englishes worldwide has questioned the ...

In vitro anti-reovirus activity of kuraridin isolated from Sophora flavescens against viral replication and hemagglutination

Journal of Pharmacological Sciences, 2015
In this study, we evaluated the anti-reovirus activity of kuraridin isolated from the roots of Sophora flavescens. In particular, we focused on whether this property is attributable to direct inhibition of reovirus attachment and/or inhibition of viral ...

Benzylpenicilloyl specific serum antibodies to penicillin in man. I. Development of a sensitive hemagglutination assay method and haptenic specificities of antibodies.

Journal of Immunology, 1966
The molecular classes of benzylpenicilloylspecific (BPO) antibodies detected in human sera by the presently described passive hemagglutination method (HA) were studied by mercaptoethanol (ME) degradation, ultracentrifugal fractionation in sucrose, and ...

Next‐Generation Bio‐Reducible Lipids Enable Enhanced Vaccine Efficacy in Malaria and Primate Models

Advanced Functional Materials, Volume 36, Issue 11, 5 February 2026.
Structure–activity relationship (SAR) optimization of bio‐reducible ionizable lipids enables the development of highly effective lipid nanoparticle (LNP) mRNA vaccines. Lead LNPs show superior tolerability and antibody responses in rodents and primates, outperforming approved COVID‐19 vaccine lipids.

A Modified Novel Validated High-Throughput Hemagglutinin Inhibition Assay Using Recombinant Virus-like Particles and Human Red Blood Cells for the Objective Evaluation of Recombinant Hemagglutinin Nanoparticle Seasonal Influenza Vaccine

Microorganisms
Currently available seasonal influenza vaccines confer variable protection due to antigenic changes resulting from the accumulation of diverse mutations. The analysis of new seasonal influenza vaccines is challenging in part due to the limitations of the
