Mitochondrial DNA Copy Number as a Potential Biomarker for the Severity of Motor Symptoms and Prognosis in Parkinson's Disease.

Background: Mitochondrial function influences Parkinson's disease (PD) through the accumulation of pathogenic alpha-synuclein, oxidative stress, impaired autophagy, and neuroinflammation. The mitochondrial DNA copy number (mtDNA-CN), representing the number of mitochondrial DNA copies within a cell, serves as an easily assessable proxy for mitochondrial function.

Objective: This study aimed to assess the diagnostic and prognostic capabilities of mtDNA-CN in PD.

hsa-mir-483-3p modulates delayed breast cancer recurrence.

Patients with estrogen receptor-positive breast cancer undergoing continuous adjuvant hormone therapy often experience delayed recurrence with tamoxifen use, potentially causing adverse effects. However, the lack of biomarkers hampers patient selection for extended endocrine therapy. This study aimed to elucidate the molecular mechanisms underlying delayed recurrence and identify biomarkers.

Clinical features of FOSMN syndrome in Korea: A comparative analysis with bulbar-onset amyotrophic lateral sclerosis.

Facial onset sensory and motor neuronopathy (FOSMN) syndrome is a rare neurodegenerative disorder initially characterized by facial sensory deficits, which later progress to motor deficits in a rostral-caudal distribution. This study investigated the prevalence, clinical features, and prognosis of FOSMN syndrome and compared these aspects with those of bulbar-onset amyotrophic lateral sclerosis (ALS) within a single institutional cohort of motor neuron diseases. We identified four patients with FOSMN syndrome who had been misclassified as having bulbar-onset ALS, representing approximately 2 % of such ALS cases.

Butterfly Cartilage Inlay Technique for Repairing Medium-to-Large-Sized Tympanic Membrane Perforations.

Objective: The butterfly cartilage inlay technique was originally developed for repairing small tympanic membrane (TM) perforations but is now increasingly used for repairing large TM perforations. Although studies have evaluated the effectiveness of butterfly tympanoplasty for repairing medium-to-large-sized TM perforations, no study has compared its effectiveness with that of the conventional underlay cartilage technique. Therefore, we aimed to evaluate the effectiveness of butterfly tympanoplasty for repairing medium-to-large-sized TM perforations compared with that of the conventional underlay cartilage.

Prospective validation and revision of predictive models for post-ERCP pancreatitis: focus on procedure-related factors and a novel risk stratification approach.

Introduction: Post-endoscopic retrograde cholangiopancreatography pancreatitis (PEP) is the most common serious adverse event after endoscopic retrograde cholangiopancreatography (ERCP). Although retrospective models to predict PEP have shown promise, their real-world applicability remains uncertain. Thus, we used prospectively derived cohort data to validate current prediction models.
