Three dose calibration curves for biodosimetry such as dicentric chromosome assay, fluorescence hybridization (FISH) assay for translocation, and micronuclei (MNs) in binucleated cell assay were established after exposure to ionizing radiation. Peripheral blood lymphocyte samples obtained from healthy donors were irradiated with Co source at a dose rate of 0.5 Gy/min to doses of 0.1-6 Gy. The results from three dose calibration curves for biodosimetry were analyzed to understand the relationship among biodosimetry assay techniques. Our comparison demonstrates that there is a very strong positive correlation among the dicentric assay, FISH, and MNs analysis, and these three biodosimetry assays strongly support the dose reconstruction and the emergency preparedness of public or occupational radiation overexposure.

Alzheimer's disease (AD) and non-AD tauopathies are dominant public health issues driven by several factors, especially in the aging population. The discovery of first-generation radiotracers, including [F]FDDNP, [C]PBB3, [F]flortaucipir, and the [F]THK series, for the in vivo detection of tauopathies has marked a significant breakthrough in the fields of neuroscience and radiopharmaceuticals, creating a robust new category of labeled compounds: tau positron emission tomography (PET) tracers. Subsequently, other tau PET tracers with improved binding properties have been developed using various chemical scaffolds to target the three-repeat/four-repeat (3R/4R) tau folds in AD.

Collaborative activities in a biological dosimetry network for radiation emergencies in South Korea.

Laboratory of Biological Dose Assessment, National Radiation Emergency Medicine, Korea Institute of Radiological & Medical Sciences, Seoul, Republic of Korea.

Purpose: Biological dosimetry is an essential analytic method to estimate the absorbed radiation dose in the human body by measuring changes in biomolecules after radiation exposure. Joint response in a network to mass-casualty radiation incidents is one way to overcome the limitations of biological dosimetry, sharing the workload among laboratories. This study aimed to investigate the current performance, collaborative activities and technical advances of the Korea biodosimetry network (K-BioDos), and suggest the future directions toward successful joint response.

Migratory birds are a natural reservoir for major respiratory viruses such as the avian influenza virus (AIV) and the avian coronavirus (AvCoV). Transmission of these viruses from migratory birds to domestic birds increases the prevalence of those diseases that cause severe economic and public health concerns in Bangladesh. The study focused on active surveillance of major respiratory viral pathogens in migratory birds, molecular identification of the viruses, and their phylogenetic origin.

Article Synopsis
  • Rapid detection of ionizing radiation exposure is essential for effective medical care during major radiological events.
  • Traditional biodosimetry assays take about 3 days for results, which delays treatment, but a new assay provides same-day results by enhancing cell yield and using a Deep Learning algorithm for dose assessment.
  • This method shows high accuracy in categorizing treatment groups and reliable dose estimation, making it a promising solution for timely interventions in large-scale radiation emergencies.
