Bioinspired Adaptive Artificial Cilia With Tunable Sensitivity and Dynamic Range for Airflow Monitoring in the Central Airway

Advanced Materials Technologies, EarlyView.
A magnetically reconfigurable airflow sensor integrated with an airway stent enables tunable sensitivity and dynamic sensing range. Airflow‐induced cantilever deformation generates resistance changes, while an external magnetic field modulates sensor stiffness, enhancing sensitivity at low airflow velocities and extending the sensing range at higher ...

Video-assisted Thoracic Surgery Lobectomy

The Korean Journal of Thoracic and Cardiovascular Surgery, 2011
Video-assisted thoracoscopic surgery (VATS) has been established as the surgical approach of choice for lobectomy in patients with early-stage non-small cell lung cancer (NSCLC). Patients with clinical stage I NSCLC with no lymph node metastasis are considered candidates for VATS lobectomy.

Video‐Assisted Intralesional Curettage for Invasive Nonmalignant Giant Cell Tumors [PDF]

Arthrosc Tech
Abstract Giant cell tumor of bone is a locally aggressive benign neoplasm with a strong tendency for local recurrence after surgical treatment. Intralesional excision and curettage is preferred in most cases to maximize tumor removal while preserving the affected joint.
