STUDY OF DOSE FORMATION FOR THE POPULATION IN RADIOACTIVELY CONTAMINATED AREAS OF ZHYTOMYR REGION BASED ON COMPREHENSIVE RADIATION-HYGIENIC MONITORING.
Probl Radiac Med Radiobiol
December 2024
WHO Country Office in Ukraine, 9B Mykhaila Hrushevskoho Str., Kyiv, 01021, Ukraine.
Objective: the research is to determine the main radiation-hygienic factors influencing the formation of radiation doses among the population of radioactively contaminated territories (RCT) in Zhytomyr region in 2024 and to analyze the dynamics of internal radiation doses based on original experimental studies conducted in reference settlements from 2012 to 2024.
Materials And Methods: In 2024, a comprehensive radiation-hygienic monitoring program was conducted in 11 settlements of Narodychi Territorial Community (TC): the Narodychi and the villages of Selets, Bazar, Rudnya Bazarska, Khrystynivka (Zone 2), Motiyki, Zalissya, Davydky, Radcha, Nova Radcha, and Grezlya (Zone 3). The comprehensive radiation-hygienic monitoring included the following activities: mobile WBC monitoring: 817 measurements (562 adults and 255 children); collection and analysis of food samples: 39 milk samples, 61 potato samples, and 57 samples of wild foods, analyzed for radionuclide content, including 137Cs and 90Sr; assessment of external radiation exposure in these settlements; surveys: 194 individuals were surveyed regarding the consumption volumes of locally produced foods from their own households and purchased foods from commercial networks.
Gadopiclenol: A q = 2 Gadolinium-Based MRI Contrast Agent Combining High Stability and Efficacy.

From the Research and Innovation Department, Guerbet, Roissy, France (I.M., M.-C.D.G., J.-F.M., A.D., Y.B., N.D., I.S., G.B., C.M., C.F., O.R., S.C.); General, Organic, and Biomedical Chemistry Unit, NMR and Molecular Imaging Laboratory, University of Mons, Mons, Belgium (C.H., S.L.); and Institute of Inorganic and Analytical Chemistry, University of Münster, Münster, Germany (C.K., T.J.M., U.K.).
Objectives: Gadopiclenol is a q = 2 pyclen gadolinium-based contrast agent (GBCA) recently approved by the Food and Drug Administration, European Medicines Agency, and other European countries. The aim of this report is to demonstrate its stability in multiple stressed in vitro conditions and in vivo, in rat kidney, while maintaining its higher relaxivity compared with conventional GBCAs on the market.
Materials And Methods: Both gadopiclenol and its chemical precursor Pi828-Gd were characterized and compared with q = 1 gadolinium (Gd) complexes.
Enhancing Clinical Trial Efficiency: The Impact of a Dual Digital Alert System on Quantitative Imaging Report Turnaround Time.
J Comput Assist Tomogr
December 2024
From the Department of Diagnostic Radiology, Abdominal Imaging, The University of Texas MD Anderson Cancer Center, Houston, TX.
Objective: This study aimed to assess the effectiveness of a dual digital alert system and automatic radiologist reassignment in improving the efficiency of quantitative imaging report delivery for clinical trials.
Materials And Methods: Assessing tumor metrics is critical to oncologic disease management, informed treatment planning, and for monitoring therapeutic response and even more so in cancer clinical research trials. A collaborative effort with the Institutional Research Information Systems division led to developing a web-based system with a Java backend, tested using Agile methodology to improve patient care with improved turnaround time (TAT) of quantitative reports.
Optimization of CZTSe Thin Films Using Sequential Annealing in Selenium and Tin-Selenium Environments.
Inorg Chem
December 2024
Laboratory of Complex Heterostructures and Multifunctional Materials, National Institute of Materials Physics, Atomistilor 405A, Magurele 077125, Romania.
CuZnSnSe (CZTSe) is a promising material for thin-film solar cells due to its suitable band gap, high absorption coefficient, and composition of earth-abundant and nontoxic elements. In this study, we prepared CZTSe thin films from Cu/SnSe and ZnSe stacks using a two-step annealing process. Initially, Cu-Sn-Se (CTSe) films were synthesized by sequential deposition and annealing of Cu and SnSe precursors in either a selenium (Se) or tin-selenium (Sn+Se) atmosphere.

December 2024
Department of Pedodontics, Faculty of Dentistry, Izmir Katip Celebi University, Izmir, Turkey.
Objectives: This study aims to comparatively assess the preventive and protective effects of the self-assembling peptide P-4 on enamel erosion and evaluate the potential for enamel surface recovery when professional products are combined with home-use dental-care products during the erosive process.
Materials And Methods: Ninety-nine bovine incisors were divided into nine groups: a control group, four groups with the application of professional-products [P-4 peptide (Curodont-Repair), stannous/Sn containing solution (8% Sn), casein-phosphopeptide-amorphous-calcium-phosphate fluoride/CPP-ACPF (MI Varnish), sodium fluoride/NaF (Profluorid)] and four groups with the combination of professional products and home-use daily dental care products [P-4 peptide (Curodont Repair + Curodont Protect), stannous ions containing agents (8% Sn+Emofluor Gel Intensive-Care), CPP-ACPF (MI Varnish + MI Paste Plus), NaF (Profluorid + ReminPro)]. Professional products were applied once before a five-day erosive cycle, involving six 2-minute citric-acid exposures per day.
