CAMP: Closed‐Loop Acoustic‐Magnetic Propulsion of Microrobots for Precision Cell Manipulation

Advanced Intelligent Systems, EarlyView.
This work demonstrates, for the first time, closed‐loop control of acoustically driven, magnetically steerable microrobots with automated speed modulation. Closed‐loop navigation allows guided motion and speed control, allowing highly accurate trajectory following. pen‐loop control enables mammalian cell manipulation via microrobots, highlighting their

Transanal Endoscopic Microsurgery [PDF]

Seminars in Colon and Rectal Surgery, 1997
Traditional methods of excising adenomas and selected carcinomas of the distal rectum provide adequate exposure and acceptable cure rates. Recurrence rates after locally excising adenomas, however, are 12% to 25%, possibly because the limited exposure has led to less than adequate resection margins.

The DAHANCA 27 Phase II Study: Transoral Laser Microsurgery for T1aN0M0 Glottic Squamous Cell Carcinoma, a Comparison to Accelerated Radiotherapy

Head &Neck, EarlyView.
ABSTRACT Introduction Endoscopic surgery of T1a glottic squamous cell carcinoma (SCC) is believed to have advantages compared to radiotherapy (RT), including short duration, cost‐effectiveness, repeatability, and RT reserved for second tumors/failures. The equality of tumor control probability after treatments is unresolved.
