Acoustic methods are often used for fisheries resource surveys to investigate fish stocks in a wide area. Commercial fisheries echo sounders, which are installed on most small fishing vessels, are used to record a large amount of data during fishing trips. Therefore, it can be used to collect the basic information necessary for stock assessment for a wide area and frequently.

- - This study explores the effectiveness of antibody testing for assessing immunity and diagnosing conditions like multisystem inflammatory syndrome related to COVID-19, focusing on antibodies targeting the SARS-CoV-2 spike protein.
- - Researchers measured the neutralizing activity of immunoglobulin-G (IgG) in COVID-19 convalescent patients, finding a strong correlation between serum neutralizing activity (IgG-EC) and specific antibodies (S-IgG).
- - The findings suggest that quantitative S-IgG tests can reliably estimate neutralizing antibody activity, provided the cut-off values for interpreting results are carefully established for accuracy.
Article Synopsis
- The study aimed to analyze changes in participant characteristics over time to improve convalescent plasma donation methods for COVID-19 patients.
- Data from April 2020 to November 2021 showed a decrease in sample eligibility, initially below 20% after a year, with a shift toward enrolling more participants beyond 120 days post-infection.
- The research concluded that monitoring eligibility rates and factors like vaccination and infection rates is crucial for effective plasma donation recruitment as pandemics evolve.
Article Synopsis
- A study was conducted to evaluate the effectiveness of convalescent plasma therapy for COVID-19 in high-risk patients who showed symptoms within five days.
- The trial involved 25 patients, with no significant difference in viral load changes between those receiving convalescent plasma and those receiving standard care over the first five days.
- The results suggest that early convalescent plasma treatment does not reduce SARS-CoV-2 viral load compared to standard care alone within that timeframe.
Introduction: Among patients with coronavirus disease 2019 (COVID-19), the factors that affect anti-severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) antibody production remain unclear. This study aimed to identify such factors among patients convalescing from COVID-19.
Methods: This study comprised patients who had been diagnosed with COVID-19 between January 1 and June 30, 2020 and gave consent for anti-SARS-CoV-2 spike protein antibody measurement using enzyme-linked immunosorbent assay during their acute and/or convalescent phases.
