tantalum/hypoxia

We anesthetized dogs, ventilated their lungs via the lower trachea, and exposed the epithelial surface of the upper trachea and coated it with powdered tantalum. Secretions from submucosal gland ducts formed elevations (hillocks) in the tantalum layer; we counted the number of hillocks that appeared

Radiotherapy (RT) is one of the most widely used cancer treatments in clinics, while hypoxia-associated resistance often occurs. Herein, a PEGylated TaOx-based oxygen-carrying nanoplatform were constructed for triple sensitizing tumor radiotherapy. The high-Z element based hollow mesoporous TaOx

BACKGROUND Endoscopic bronchoplastic procedures, such as metal stent implantation, are for safety reasons and mainly performed using rigid bronchoscopy. Major complications, such as bleeding and accidental airway occlusion, are thought to be better managed with the rigid device. An increasing number

Improving tumor oxygenation and concentrating X-ray radiation energy inside the tumor have received considerable attention in cancer radiotherapy. Herein, core-shell tantalum oxide@manganese dioxide (TaOx@MnO₂) nanostructures are prepared as an efficient radiosensitizer for enhancing
