Recent Advances in Ionizing Radiation as a Nonequilibrium Chemical Field for Catalysis

open access: yesCarbon and Hydrogen, EarlyView.
Ionizing radiation acts as a nonequilibrium chemical field that generates reactive species and structural perturbations. These radiation‐induced effects bridge catalytic material construction, including metal loading, framework evolution, defect engineering, and carbon‐network reorganization, with selective transformations such as oxidation, reduction,

Current Evidence on Best Practice Dental Survivorship Care for People With Head and Neck Cancer: An Overview of Systematic Reviews and Emerging Evidence

open access: yesHead &Neck, EarlyView.
ABSTRACT Introduction Head and neck cancer (HNC) survival is improving, increasing the need to address long‐term survivorship issues. Dental survivorship—care before, during, and after treatment—remains inconsistent across services. We conducted a review of systematic reviews and emerging evidence to inform contemporary dental survivorship care for HNC

Dose‐Dependent Efficacy of Radioiodine Therapy in Pediatric Graves’ Disease: A Retrospective Study of Hypothyroidism Risk and the Predictive Role of Thyroid Hormone Parameters

open access: yesiRADIOLOGY, EarlyView.
RAI therapy demonstrated time‐dependent efficacy in pediatric Graves' disease, with gradually increasing treatment success and hypothyroidism incidence during follow‐up. Higher planned activity (≥ 0.15 mCi/g) was associated with a higher successful rate than lower planned activity (< 0.15 mCi/g), and LASSO analysis identified FT3 and TSH as candidate ...

Determination of metals concentration in sedimentary profiles from lagoons affected by the tailings from the collapse of the Fundão dam

open access: yesBrazilian Journal of Radiation Sciences
The collapse of the Fundão dam in Mariana released more than 59 million m³ of tailings, which flowed almost 700 kilometers along the Doce river, through the states of Minas Gerais and Espírito Santo, reaching the estuary and into the Atlantic Ocean.

The Impact of Genetic Polymorphisms on Genotoxicity (DNA Damage) Among Children Exposed to Environmental Mutagens: A Systematic Review

open access: yesJournal of Applied Toxicology, EarlyView.
ABSTRACT Children, as a particularly vulnerable group, are more susceptible to these mutagens due to their developing immune systems, higher physiological vulnerability, and increased exposure through behaviors like outdoor play and hand‐to‐mouth activities. This review aims to investigate the relationship between these environmental exposures, genetic
