Using organic metal nanohybrid structures to simultaneously identify multiple food poisoning bacteria

Osaka Metropolitan University scientists have developed a simple, rapid method to simultaneously identify multiple food poisoning bacteria, based on color differences in the scattered light by nanometer-scaled organic metal nanohybrid structures (NHs) that bind via antibodies to those bacteria.

SARS-CoV-2 antigen levels associated with COVID-19 severity and other clinical outcomes

The amount of SARS-CoV-2 antigen measured in the blood of patients hospitalized with COVID-19 is associated with illness severity and other clinical outcomes, according to a new study published in the Annals of Internal Medicine.

Microscopy technique enables visualization of unseen nanostructures within cells and tissues

Inside a living cell, proteins and other molecules are often tightly packed together. These dense clusters can be difficult to image because the fluorescent labels used to make them visible can't wedge themselves in between the molecules.

Study identifies two potential serological biomarkers of monkeypox infection

In a new study, researchers pursued two monkeypox virus (MPXV) immune targets, A35R and H3L, that could be deployed in a serological assay to identify recent MPXV cases.

What are the effects of e-cigarettes and their constituents on SARS-CoV-2 infection?

In a new study, researchers evaluated whether e-cigarette (EC) aerosols promoted severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection.

How does the maternal immune response balance SARS-CoV-2 antiviral responses with transplacental transfer of protection to the fetus?

Researchers found that in SARS-CoV-2 maternal infection, the balance between antiviral response and transplacental transfer of humoral and cellular protection relies on maternal IL-6 and IL10.

Study shows SARS-CoV-2 infection provides strong protection from reinfection

Researchers assess the durability and effectiveness of immune responses against SARS-CoV-2 in terms of spike-binding antibody titers.

New study provides comparison of replicating and non-replicating vaccines against SARS-CoV-2

A new study reported a single-cell adenovirus (SC-Ad) which replicates the antigen genes substantially without producing infectious progeny.

New universal flu vaccine protects mice against diverse variants of influenza A and B viruses

A new universal flu vaccine protects against diverse variants of both influenza A and B viruses in mice, according to a new study by researchers in the Institute for Biomedical Sciences at Georgia State University.

What is the link between influenza vaccination and the severity of COVID-19 infection?

Researchers performed a systematic review and meta-analysis to investigate whether influenza vaccinations could reduce COVID-19 severity outcomes.
