Six radical surgeries for metachronous multiple primary lung cancer: A case report.

Introduction And Importance: Comprehensive reports on surgery for metachronous multiple primary lung cancers after the third or subsequent surgeries are lacking. Herein, we report a case in which six radical surgeries were performed for metachronous primary lung cancer.

Case Presentation: The patient was a 62-year-old man when he underwent his first surgery, a right lower lobectomy, and the pathological diagnosis was adenocarcinoma.

Investigating the Impact of Carbon Fiber as a Wheelchair Frame Material on Its Ability to Dissipate Kinetic Energy and Reduce Vibrations.

Using a wheelchair over uneven terrain generates vibrations of the human body. These vibrations result from mechanical energy impulses transferred from the ground through the wheelchair components to the user's body, which may negatively affect the quality of the wheelchair use and the user's health. This energy can be dissipated through the structure of the wheelchair frame, such as polymer and carbon fiber composites.

The impact of vascular division sequence and epithelial-mesenchymal transition status on postoperative recurrence in lung adenocarcinoma.

Background: The vascular division sequence in video-assisted thoracic surgery (VATS) lung resection is usually determined by the handling difficulty due to the limited surgical view through the scope. However, upfront pulmonary vein division is theoretically desirable to avoid tumor cells spreading by surgical manipulation. Epithelial-mesenchymal transition (EMT) is associated with poor prognosis and an increased number of circulating tumor cells.

Life-saving emergency surgery due to delayed massive hemothorax 7 days after fall injury: a case report.

Background: Delayed hemothorax after thoracic trauma complicates approximately 7.4-36% of blunt traumas. Cases of delayed hemothorax that suddenly increase and require surgery are rare.

Nanotechnology in Fire Protection-Application and Requirements.

Nanotechnology is used, to an increasing extent, in practically every aspect of the economy and society. One area where nanotechnology is constantly advancing is fire protection. Nanostructures are found in elements used in direct protection, such as in protective clothing, filters, and helmets.
