Research team led by YCU professor successfully develops a rapid diagnostic test for COVID-19 that can detect antiviral antibodies in patient serum

A research group led by Professor Akihide Ryo of Yokohama City University Graduate School of Medicine’s Department of Microbiology has successfully developed Enzyme-Linked Immunosorbent Assay (ELISA) and a rapid immunochromatographic test which can specifically detect the IgG SARS-CoV-2 antibodies.

Visualization of AMPA receptors in living human brain with positron emission tomography

Although aberrations in the number and function of glutamate AMPA (α-amino-3-hydroxy-5-methyl-4-isoxazole propionic acid) receptors are thought to underlie neuropsychiatric disorders, no methods are currently available for visualizing AMPA receptors in the living human brain. Here we developed a positron emission tomography (PET) tracer for AMPA receptors. A derivative of 4-[2-(phenylsulfonylamino)ethylthio]-2,6-difluoro-phenoxyacetamide radiolabeled with 11C ([11C]K-2) showed specific binding to AMPA receptors.

Accurate identification of dimers from α‐pinene oxidation using high‐resolution collision‐induced dissociation mass spectrometry

Interest in mass spectrometry of highly oxidized dimers from α‐pinene oxidation has increased in the atmospheric chemistry field. Here, we apply high‐resolution collision‐induced dissociation mass spectrometry (HR‐CID‐MS) with an atmospheric pressure ionization source to investigate in detail how α‐pinene‐derived dimers are detected and identified by MS.
