The COVID-19 global pandemic is still affecting the world, even considering vaccine applications in most countries, especially due to new variant outbreaks and possibility that they may present immunological escape. Therefore, mass testing relevant infection monitoring restriction policy evaluations, making low-cost easy-to-use tests essential. Serological might also be useful immune response a...

fast enzyme linked immunosorbent assay (fast-elisa) was compared with the standard elisa for the diagnosis of human hydatidosis. seventy serum samples including 30 from hydatidosis patients (surgically confirmed), healthy control individuals not infected with any parasitic diseases (n=/20) and from others with different parasitic infections including, toxocariosis (n=5), fasciolosis (n=5), tric...

BACKGROUND Despite their ease of use, lateral flow immunoassays (LFIAs) often suffer from poor quantitative discrimination and low analytical sensitivity. We explored the use of a novel class of europium chelate-loaded silica nanoparticles as labels to overcome these limitations. METHODS Antibodies were covalently conjugated onto europium chelate-loaded silica nanoparticles with dextran as a ...

Background: Multiple sclerosis (MS) is a chronic, demyelinating disease of the CNS in which autoimmunity to myelin plays a role in pathogenesis. Infection with common viruses, particularly EpsteinBarr virus (EBV), is postulated to contribute to the pathobiology of MS. Epidemiological studies suggest an association between infection with EBV and risk of MS. To characterize the IgG antibody to th...
