P1.095. International Collaborative Study on the Relationship Between ALDH2 Gene Polymorphism and Changes in Salivary Acetaldehyde Concentration by L8020 Lactobacillus

Abstract Topic Esophageal Cancer: Esophageal Carcinogenesis Background Seventy-five percent of the world's esophageal cancer cases occur in Asia. The primary cause is the presence of the flasher (ALDH2 non-inactivating type). The ALDH2 gene polymorphism (rs671 G>A) is believed to...

De-escalation of perioperative systemic therapy for early breast cancer.

Breast cancer is the most common malignancy among women worldwide, and the number of survivors continues to increase owing to earlier detection and advances in treatment. As long-term survivorship becomes increasingly important, minimizing treatment-related toxicity without compr...

Revisiting low-voltage interpretation: Chamber-specific relationships between myocardial wall thickness and omnipolar voltage

Electrogram voltage reflects multiple factors, including viable myocardial mass, structural integrity, electrode configuration, catheter orientation, and activation sequence. How local myocardial wall thickness (WT) contributes to voltage amplitude in structurally intact myocardi...

Pleistocene Basaltic Volcanism on the Fly Platform in Papua New Guinea

Papua New Guinea (PNG) remains one of the least studied regions in the Southwest Pacific, and the tectono-magmatic evolution of extensive areas such as the Fly Platform remains poorly constrained. This study presents the first investigation of basaltic volcanism on the Fly Platfo...

De novo epilepsy after the occipital transtentorial approach: association with occipital lobe injury and persistent FLAIR lesions

The occipital transtentorial approach (OTA) is a useful surgical corridor for deep-seated lesions involving the pineal region, thalamus, ventral temporal structures, and posterior fossa. Although occipital lobe injury is a recognized complication of OTA, its relationship with pos...

Detection of Weld Root Crack in Metal Plates with Convolutional Neural Network

The detection of weld root cracks in metal plates using nonlinear ultrasonics and a convolutional neural network (CNN) was investigated. Lamb waves with a fundamental frequency of 0.5 MHz were transmitted into a carbon steel plate specimen, and the waveforms were recorded using a...

Bone-preserving ankle arthrodesis after infected pilon fracture nonunion: lessons from tapered distal docking and fibular-supported reconstruction

Infected nonunion after severe pilon fracture remains a major challenge in limb reconstruction, particularly when chronic infection and repeated debridement result in severe metaphyseal bone loss and compromised distal tibial morphology. In such cases, conventional resection to c...
