Summary: 18F-labeled fluorothiophosphate (FTP) synthons with high radiochemical yields can be rapidly generated in reaction solutions using wet [18F]F- without the need for substrate pre-modification or lengthy radiosynthesis procedures. This simplified one-pot 18F-labeling method allows for the visualization and translation of a variety of biomolecules, making it valuable for modern positron emission tomography techniques.

Summary: Oceans cover 97% of the Earth's water and are home to microscopic plankton that play a crucial role in global biogeochemical cycles. However, assessing marine plankton has been challenging due to the vastness of the oceans and the logistical and economic constraints of sampling. In this study, researchers present a modular open-source strategy called PlanktoScope, which allows for versatile and reconfigurable imaging of plankton samples. The PlanktoScope is small, affordable, and can be controlled from any WiFi-enabled device, making it suitable for both laboratory and field use.

Summary: This study synthesized two PET probes and evaluated their permeability through the blood-brain barrier and affinity towards GSK-3 alpha/beta. The results showed that [F-18]F-CNPIFE had higher brain uptake compared to [F-18]F-CNBI, making it a promising PET probe for imaging GSK-3 alpha/beta.

Summary: The on-site microfluidic serological assay proposed in the study allows for timely decisions to be made regarding patient status and population-wide screening for controlling the COVID-19 pandemic. The developed assay showed enhanced sensitivity and specificity for clinical samples of SARS CoV-2 patients, enabling daily monitoring of IgM/IgG titers and patterns to provide important insight into the immune response to the virus. Monitoring these titers promotes rapid on-site detection and comprehensive understanding of the immune response in COVID-19 patients.

Summary: The possibility of (AlF)-F-18-radiolabeling using the N,N'-bis [2-hydroxy-5-(2-carboxyethyl)benzyl] ethylenediamine-N, N'-diacetic acid motif in protic alkanolammonium ionic liquids is reported for the first time. Ionic liquids containing triethanolammonium or triisopropanolammonium cations were found to be the most promising, achieving high radiochemical conversion with minimal precursor amounts.

Summary: Focused ultrasound in combination with microbubbles enhances therapeutics delivery to the brain by increasing blood-brain barrier permeability. PET imaging using [F-18]FDS is evaluated as a marker for BBB integrity, showing significantly increased distribution in the brain after FUS. These findings demonstrate the potential of [F-18]FDS PET as a sensitive and reproducible marker for noninvasive monitoring of BBB disruption induced by FUS in vivo.

Summary: Low bone mineral density (BMD) was found to be common in oncologic patients undergoing F-18-FDG PET/CT. Decreased F-18-FDG avidity of bone marrow correlated with decreased BMD, validating the link between osteoporosis and bone marrow fat. CT attenuation value of L1 vertebrae could serve as a simple and accurate approach for detecting patients at risk for osteoporosis-related fractures using PET/CT data.

Summary: In this study, the role of [18F]FDG-PET/CT in identifying and managing cancer of unknown primary site (CUP syndrome) was assessed. Results showed a relatively good effectiveness of [18F]FDG-PET/CT in detecting primary tumors, especially in non-SCC type patients. However, the detection rate was lower in SCC patients. Additionally, [18F]FDG-PET/CT had a positive impact on the clinical management of patients with discovered primary tumors.
