Drosophila pyruvate kinase links metabolic state with circadian output via TARANIS and PDF

Abstract The circadian clock generates ∼24-hour rhythms that anticipate daily environmental changes. Circadian clock and glucose metabolism are tightly interconnected, and both are disrupted in aging and disease. To examine how glucose hypometabolism impacts circadian rhythm, we...

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...

Stereotactic body radiation therapy for hepatocellular carcinoma: 2026 expert consensus-based practical recommendation of the Korean Liver Cancer Association

Stereotactic body radiation therapy (SBRT) is a noninvasive, high-precision radiation technique that delivers a high dose to the tumor in a limited number of fractions, typically five or fewer, and is increasingly used as a curative-intent option for hepatocellular carcinoma (HCC...

Korean Clinical Practice Guidelines for Rehabilitation in Critically Ill Patients and Post-Intensive Care Syndrome

Background: Survivors of critical illness commonly experience persistent physical, cognitive, and psychological impairments, collectively known as post–intensive care syndrome. Although intensive care unit (ICU) rehabilitation is now recognized as an important part of recovery af...

Milvexian with Antiplatelet Therapy after Acute Coronary Syndrome Event

BackgroundPatients are at increased risk for recurrent ischemic events after an acute coronary syndrome event. Milvexian, an oral factor XIa inhibitor, may reduce the risk of major adverse clinical events with minimal bleeding risk. MethodsIn this phase 3, randomized, placebo-con...

Asian Neurogastroenterology and Motility Association and Asia-Pacific Association of Gastroenterology Chronic Constipation Consensus 2026.

Background/Aims: : Chronic constipation is a common gastrointestinal (GI) disorder in Asia, characterized by heterogeneous symptom presentation, frequent overlap with other GI symptoms, and limited access to specialized diagnostic tests in many settings. These factors contribute...

GRP78/BiP as a novel midbody component induces mitotic exit failure via PLK1 stabilization in hepatocellular carcinoma

Hepatocellular carcinoma (HCC) is the third leading cause of cancer-related mortality worldwide and is associated with a poor prognosis, even when diagnosed in its early stages. Therefore, identifying novel HCC targets for therapeutic drug development is critically needed. Our pr...

Per Protocol Analysis and Long‐Term Outcomes of Laparoscopic Radical Resection for Gallbladder Cancer Compared With Open Method

BACKGROUND: Although laparoscopic radical resection for gallbladder (GB) cancer has been attempted, only a limited number of studies have evaluated its outcomes using a per-protocol analytical approach. METHODS: Between January 2010 and December 2019, 213 patients underwent surge...

Safety and Effectiveness of Intramuscular Dexmedetomidine Versus Per-Rectal Thiopental for Pediatric Brain Computed Tomography Sedation: A Retrospective Cohort Study.

OBJECTIVES: Following per-rectal thiopental (PR-THP) supply discontinuation, a tertiary pediatric emergency department in Korea transitioned to intramuscular dexmedetomidine (IM-DEX) for brain computed tomography (CT) sedation. We evaluated the safety and effectiveness of this pr...

Long-term follow-up results of topical imiquimod for high-grade cervical intraepithelial neoplasia in young women: an original research

<title>Abstract</title> Background As cervical excisional treatment is associated with adverse pregnancy outcomes, imiquimod has been explored in several studies—such as the TOPIC-3—as an alternative but without success. Therefore, we designed a study focusing on patients aged &l...

Polynucleotides Attenuate Atopic Dermatitis-like Inflammatory Signaling in Keratinocytes and Macrophages

Background: Atopic dermatitis (AD) is a persistent and recurring skin disease characterized by epidermal barrier dysfunction, immune dysregulation, and elevated expression of proinflammatory mediators. We investigated the anti-inflammatory potential of polynucleotides (PN), highl...

Clinical Characteristics and Outcomes of Pediatric Patients With Long QT Syndrome: A Korean Multicenter Cohort Study

This multicenter nationwide cohort study comprehensively analyzed the clinical features, genetic architecture, and outcomes of Korean pediatric patients with long QT syndrome (LQTS).Prolonged QT intervals, fetal arrhythmia, and LQT2/3 genotypes compared to LQT1 were independent r...

Prenatal PM2.5 exposure drives epigenetic reprogramming of fetal macrophages linked to atopic dermatitis

Abstract Prenatal environmental exposures are increasingly recognized as contributors to atopic dermatitis (AD), yet the underlying mechanisms remain unclear. Fine particulate matter (PM 2.5 ), a complex mixture of airborne pollutants, has been associated with elevated risk of al...

Repositioning of cis-flupentixol for the suppression of ovarian cancer cell migration and invasion through ERK5 inhibition

Ovarian cancer (OC) remains the most lethal gynecological malignancy, largely because of its late-stage diagnosis and limited effective screening modalities. Despite therapeutic advances, high relapse rates and therapeutic resistance—particularly in metastatic disease—underscore...

Integrative Genomic Analysis Reveals Molecular and Clinical Disparities between Bladder and Upper Tract Urothelial Carcinoma in K-MASTER Program

Purpose: The clinical outcome of urothelial carcinoma presents significant variability, reflecting its molecular composition, epidemiologic attributes, and primary site of origin. Despite histological similarities, upper tract urothelial carcinoma (UTUC) and bladder urothelial ca...

Phenotyping Sepsis at Emergency Department Presentation Using Early Clinical Data: A Multicenter Cohort Study

Background: Sepsis is heterogeneous, and early emergency department (ED) management is constrained by limited information and dynamic clinical trajectories. Methods: Using the nationwide Korean Sepsis Alliance (KSA) registry, we applied k-means clustering to nine routine ED varia...

Blood viscosity is associated with smoking status rather than the presence of chronic obstructive pulmonary disease: findings from the Korea COPD Subgroup Study (KOCOSS)

Abstract Background The relationship between smoking and blood viscosity is well established. However, the role of blood viscosity in the development of chronic obstructive pulmonary disease (COPD) and its impact on lung function decline remains unclear. Therefore, we aimed to in...

Selective Neurectomy and Masseteric-to-Zygomatic Nerve Transfer With Processed Nerve Allograft for Postparalytic Ocular Sequelae: Preliminary Results

Oro-ocular synkinesis is a debilitating sequela of facial nerve injury. While selective neurectomy (SN) offers a surgical alternative to botulinum toxin, its efficacy is often limited by recurrence. This study evaluates the feasibility and preliminary results of combining targete...
