Astrocytic ET‐1 System Determines Microglia Phenotype Following Spinal Cord Injury

Advanced Science, EarlyView.
The study reveals that astrocytic ET‐1 system is solely activated by thrombin following SCI via RhoA/NF‐κB and MAPKs/NF‐κB signal pathway. The release of astrocytic ET‐1 drives microglia polarization toward M1 phenotype through YAP signaling via ETA and ETB receptors.

Osteopenic occult vertebral fracture is associated with poor oncological outcome in patients with hepatocellular carcinoma after hepatic resection

Annals of Gastroenterological Surgery, EarlyView.
Osteopenic occult vertebral fracture (OVF) was associated with poor long‐term outcomes in patients with HCC after hepatic resection. Osteopenic OVF had a poorer prognosis than that of patients with either osteopenia or OVF. Abstract Background Although osteopenia has been associated with poor outcomes in patients with hepatocellular carcinoma (HCC ...

Automated Segmentation of Vertebrae on Lateral Chest Radiography Using Deep Learning [PDF]

arXiv, 2020
The purpose of this study is to develop an automated algorithm for thoracic vertebral segmentation on chest radiography using deep learning. 124 de-identified lateral chest radiographs on unique patients were obtained. Segmentations of visible vertebrae were manually performed by a medical student and verified by a board-certified radiologist.

VertXNet: Automatic Segmentation and Identification of Lumbar and Cervical Vertebrae from Spinal X-ray Images [PDF]

arXiv, 2022
Manual annotation of vertebrae on spinal X-ray imaging is costly and time-consuming due to bone shape complexity and image quality variations. In this study, we address this challenge by proposing an ensemble method called VertXNet, to automatically segment and label vertebrae in X-ray spinal images.

Salvage esophagectomy for unresectable locally advanced esophageal squamous cell carcinoma: Significant or not?

Annals of Gastroenterological Surgery, EarlyView.
Abstract We reviewed the current status and perspectives on salvage esophagectomy for initially unresectable locally advanced esophageal squamous cell carcinoma (ESCC) in the era of minimally invasive surgery and immunotherapy. Although the standard treatment for these patients is definitive chemoradiotherapy (CRT), the complete response rate to CRT ...
