Comprehensive Approach to Cytomorphology in Liquid-Based Bile Duct Brush Cytology: Integrating Cell Blocks and Histology.

Bile duct brush cytology is a widely used and essential method for evaluating biliary tract lesions, although it remains challenging for pathologists. Liquid-based preparations provide a better vision of morphology and enable the preparation of cell blocks, thereby enhancing reliability. However, the establishment of reproducible interpretation criteria and utilization of cell blocks remain limited.

A Prospective Randomized Trial Comparing 2 Different Paclitaxel-Coated Balloons in De Novo Coronary Artery Disease.

Background: The Genoss paclitaxel-coated balloon (PCB) is a novel PCB with shellac and vitamin E as excipients, enhancing drug delivery to the target lesion and minimizing restenosis.

Objectives: This study aimed to compare quantitative coronary angiographic outcomes at 6 months after treatment of de novo coronary artery disease (CAD) with 2 different types of PCBs.

Methods: This prospective, multicenter, noninferiority trial randomized 204 patients with chronic coronary syndrome or stabilized acute coronary syndrome to treatment with the shellac and vitamin E-based PCB or the reference PCB (SeQuent Please NEO) in a 1:1 ratio.

Enhancing neural stem cell integration in the injured spinal cord through targeted PTEN modulation.

Spinal cord injury results in permanent loss of neurological functions due to severance of neural networks. Transplantation of neural stem cells holds promise to repair disrupted connections. Yet, ensuring the survival and integration of neural stem cells into the host neural circuit remains a formidable challenge.
