Through theoretical derivation, researchers have concluded that a simple linear relationship exists between the reactivity of molten salt reactors and the reciprocal of uranium concentration in the fuel salt. This relationship has been validated through numerical simulations, demonstrating its general applicability, which is expected to have a far-reaching impact on the theoretical development of reactor physics.
This study in neonatal rats revealed that the common inhaled pediatric anesthetic, sevoflurane, impairs neurogenesis and causes cognitive deficits by suppressing fatty acid β-oxidation (FAO) within neural stem/progenitor cells. The research pinpointed that enhancing FAO activity can significantly mitigate the neuronal damage induced by sevoflurane. This discovery provides a novel perspective on anesthetic-related neurodevelopmental toxicity and establishes a foundational theory for future strategies aimed at protecting brain function in infants and children undergoing anesthesia.
China’s Free Teacher Education (FTE) scholarship program, launched in 2007, aims to attract top students into teaching and address teacher shortages in underdeveloped regions. A new study finds that FTE scholarships draw high-performing students who are more likely to end up as teachers. Despite experiencing slightly higher burnout, these scholarship recipients demonstrate superior teaching effectiveness.
This study analyzed polypharmacy in Côte d'Ivoire using insurance data (2014−2018). It found a high prevalence of multiple medication use, especially among children under 15. While overall rates decreased over time, significant geographic disparities persisted, with some regions having up to 9 times higher odds of persistent polypharmacy. The findings highlight a critical public health issue and the need for interventions to promote rational medicine use across all regions.
This empirical study demonstrates that a multi-criteria decision analysis (MCDA) framework is a feasible and consistent supplementary tool for evaluating the value of orphan medicinal products (OMPs) in China. Applying the framework to three OMPs, laronidase, emicizumab, and dimethyl fumarate (DMF), yielded consistent quantitative scores between independent assessor groups, establishing a clear value priority order.
Integrated writing (IW) requires learners to synthesize multiple sources of information for a written response. It has become a key component of language education and assessment globally. A new integrative review synthesizing two decades of research reveals that Chinese IW is a complex construct influenced by individual psychological factors and shows strong associations between the first- and second-language skills, offering valuable insights for teaching and assessment.
This forecasting study analyzes the impact of the Inflation Reduction Act (IRA) on diabetes drug costs for Medicare in Louisiana, USA. It finds that price negotiations for three non-insulin drugs are projected to save approximately $400 million over five years (2026−2030). A key driver of savings is a shift in medication use, as patients are expected to switch from non-negotiated to negotiated drugs due to lower costs.
