Impact of a prolonged nationwide residents’ strike on acute ischemic stroke care in a metropolitan city

Abstract BackgroundAcute ischemic stroke (AIS) requires timely management in both prehospital and in-hospital phases to optimize outcomes. In 2024, South Korea experienced a prolonged nationwide residents’ strike that disrupted the healthcare system, potentially affecting AIS man...

Comparative evaluation of multicellular tumor spheroid fabrication platforms for reliable drug screening

Abstract Multicellular tumor spheroids (MTS) are widely used three-dimensional tumor models in various biomedical fields. Despite the increasing use of MTS, systematic comparisons providing practical information for selecting fabrication platforms according to experimental object...

Teachers’ mental health from the perspectives of moral injury and institutional betrayal, and on trauma-sensitive organizational environments: a narrative review

Teachers' mental health is a critical public health concern in South Korea. The current educational environment, characterized by intensifying parent-teacher conflicts, legal disputes, and increasing administrative burdens, demonstrates the limitations of interpreting these chall...

Growing carbapenem resistance in South Korea with long-term care facilities as reservoirs

Abstract South Korean CRE notifications more than doubled between 2020 and 2024, with no inflection in the trajectory. Imipenem resistance in long-term care facilities reached 52.3% for Klebsiella pneumoniae and a 12.93-fold higher risk ratio than small/medium hospitals for Esche...

Artificial intelligence anxiety: a narrative review of psychiatric conceptualization and clinical management

Artificial intelligence (AI) is gradually permeating every aspect of daily life. AI is now more than a mere tool; it significantly influences individual capabilities, professional values, social status, and our perspectives on the future. Amid these AI-driven changes, the concept...

TrivalentAl Insertion into Layered-Oxide-DerivedPerovskite Oxynitrides for Defect-Controlled Dielectric Response

Abstract Al-containing perovskite oxynitrides, SrAl0.2M0.8O2.4N0.6 (M = Nb, Ta), were synthesized by ammonolysis of layered Sr5M4O15 precursors with α-Al2O3. This reaction demonstrates that the cation-insertion chemistry of layered-perovskite-derived oxynitrides can be extended t...

Multivariate characterization of foliar morpho-anatomical traits supporting adaptive trends and taxonomic resolution in halophytic grasses

Leaf morphology and epidermal traits of 15 salt-tolerant grasses belonging to 10 genera from the Bahadur Khel Salt Range were examined using a microscopic technique for the first time. Eight qualitative characters (epidermal cell shape, anticlinal wall patterns, type of stomata a...

In-Situ anchoring of amorphous NixB nanoparticles onto Nb2CTx MXene nanosheets for high-performance asymmetric supercapacitors

An amorphous nickel boride/niobium carbide MXene (Ni x B/Nb 2 CT x ) composite was designed and synthesized via a combined HF-assisted etching and in-situ chemical reduction strategy. The uniform anchoring of 0D Ni x B nanoparticles within the multilayered Nb 2 CT x nanosheets le...

Rational Designof Pyrrole-Based Ionizable Lipidsfor mRNA Delivery

Abstract Ionizable lipids are key components of lipid nanoparticles for mRNA delivery. Inspired by the DLin-KC2-DMA ionizable lipid, we developed a series of pyrrole-based ionizable lipids to evaluate the feasibility of incorporating a rigid heterocyclic scaffold into ionizable l...

Dynamics, function, and regulation of mammary stem cells in development and disease

Understanding the heterogeneity of mammary epithelial cells and their contributions to postnatal development and regeneration is of great importance. Recent advances have defined the intrinsic complexity of the mammary epithelium, its stromal interactions, and the ontogeny of adu...
