Reconstruction of Evolutionary History of Pleurostomatid Ciliates (Ciliophora, Litostomatea, Haptoria): Interplay of Morphology and Molecules

Vďačný, Peter, Rajter, Ľubomír, Shazib, Shahed Uddin Ahmed, Jang, Seok Won, Kim, Ji Hye, Shin, Mann Kyoon (2015): Reconstruction of Evolutionary History of Pleurostomatid Ciliates (Ciliophora, Litostomatea, Haptoria): Interplay of Morphology and Molecules. Acta Protozoologica 54...

Contrasting Prognostic Value of Discordance Between Resting Distal-to-Aortic Coronary Pressure Ratio and Fractional Flow Reserve in Coronary Artery Disease

BACKGROUND: Discordance between nonhyperemic pressure ratios and fractional flow reserve (FFR), observed in up to 20% of cases, complicates clinical decision-making for coronary revascularization and warrants further investigation of its clinical implications. This study aimed to...

Comparison of Uncovered and Covered Biliary SEMS for the Salvage of Obstructed SEMS: A Multicenter Retrospective Propensity Score–Weighted Study

BACKGROUND AND AIMS: Recurrent biliary obstruction (RBO) is common after uncovered self-expandable metal stent (UCSEMS) placement in unresectable distal malignant biliary obstruction. We compared stent patency, clinical outcomes, and RBO patterns between fully covered (FCSEMSs) a...

Ultrahigh Detectivity Colloidal Quantum dot Avalanche Photodetectors Driven by Electron Mobility of the n‐Type Layer

ABSTRACT Colloidal quantum dots (CQDs) are pragmatic candidates for infrared photodetectors due to their high absorption coefficient in the infrared region and solution processability. In addition, an incorporation of avalanche multiplication within the CQD region offers a route...

Vascular Imaging Features and Time-Specific Recurrence Risk After Craniocervical Artery Dissection

Background and ObjectivesCraniocervical artery dissection (CCAD) is a major cause of stroke in young adults, yet its recurrence risk remains poorly defined because of delayed enrollment in prior research. We aimed to determine the temporal distribution of recurrent ischemic strok...

Metabolic health, obesity, and prognosis in chronic obstructive pulmonary disease

Metabolic syndrome is a common comorbidity in chronic obstructive pulmonary disease (COPD), yet its long-term impact on survival and exacerbations remains controversial. We investigated whether metabolic health status and body mass index (BMI) influence mortality and the rate of...

Explainable machine learning on repeated screening data for risk-stratified diabetes care: a dual-level interpretability approach

In South Korea, national health screening intervals are determined by occupational category: typically, annual screening for non-office workers and biennial screening for office workers. To enable proactive prevention, it is critical to understand how these screening intervals an...

Extended treatment duration and recurrence in successfully treated drug-susceptible pulmonary tuberculosis with cavity on chest radiograph

Background Cavity on chest radiograph is recognized as an independent risk factor for recurrence in pulmonary tuberculosis (TB), but evidence supporting extended treatment in these patients remains limited, particularly in real-world data from Korea. Methods We performed a retros...

Discordant Antitumor Efficacy with Compromised Survival in High-Risk Unresectable Hepatocellular Carcinoma

Background/Objectives: Real-world data in high-risk patients remain limited; this study evaluated survival, safety, and prognostic factors in this patient group. Methods: This multicenter study retrospectively reviewed 783 patients who received Ate/Bev from 2022–2024 across South...

Nonreciprocal Vortex Pinning and Re-entrant Superconductivity through Niobium Interface Design

Abrikosov vortex motion in type-II superconductors generates finite resistance under applied current, limiting practical use. Traditional suppression via defect engineering is complex and hard to reproduce. Here, we show that interfacial engineering-specifically, tuning the penet...

Changing Clinical Characteristics, Diagnostic Patterns, and Outcomes of Tuberculosis in South Korea: The Korean Tuberculosis Cohort, 2019-2024

BACKGROUND: Tuberculosis (TB) remains a public health concern in South Korea despite declining national notifications. We evaluated temporal changes in clinical characteristics, diagnostic patterns, and treatment outcomes in the Korean Tuberculosis Cohort (KTBC) from 2019 to 2024...

Danburstotug, an anti‐ PD ‐ L1 antibody, in relapsed/refractory extra‐nodal natural killer/T‐cell lymphoma: The phase 2 DISTINKT study

Summary Relapsed/refractory extra‐nodal natural killer/T‐cell lymphoma (R/R ENKTL) has limited treatment options. Danburstotug, an antibody targeting programmed death‐ligand 1 (PD‐L1), was evaluated in adults with R/R ENKTL in a phase 2, open‐label study (NCT04414163). Danburstot...

Maternal diabetes and childhood cancer risks in offspring: a nationwide cohort study

Maternal diabetes is associated with several adverse childhood outcomes, but its link to childhood cancer remains inconclusive. We investigated this in a nationwide birth cohort using the Korean National Health Insurance database. We analyzed women who delivered singletons betwee...
