Tracheal regeneration in long-term survivors with silicone prosthesis

Dogs that achieved long-term survival (15 to 36 months) following insertion of a silicone tracheal prosthesis exhibited tracheal wall and ring formation around the loosened prosthesis. The new trachea was observed in 6 dogs and fulfilled all the criteria of an ideal tracheal substitute except inner epithelialization.     

A gastroplasty for short esophagus and reflux esophagitis: experimental and clinical studies.

A safe, simple, effective gastroplasty for short esophagus with reflux esophagitis is described. It has been evaluated in dogs for up to three years with flexible fiberesophagoscopy, esophagrams and intraluminal pressure studies. Successful clinical experience has been encouraging.     

Advances in Optical Spectroscopy and Imaging of Breast Lesions

A review is presented of recent advances in optical imaging and spectroscopy and the use of light for addressing breast cancer issues. Spectroscopic techniques offer the means to characterize tissue components and obtain functional information in real time. Three-dimensional optical imaging of the breast using various illumination and signal collection schemes in combination with image reconstruction algorithms may provide a new tool for cancer detection and treatment monitoring.
