OBJECTIVE To establish a telerobotic surgical service between a teaching hospital and a rural hospital for provision of telerobotic surgery and assistance to aid rural surgeons in providing a variety of advanced laparoscopic surgery to their community patients. SUMMARY BACKGROUND DATA The above service was established between St. Joseph's Hospital in(More)
OBJECTIVE It has been suggested that robotic-assisted remote telepresence surgery with a signal transmission latency of greater than 300 ms may not be possible. METHODS We evaluated the impact of four different latencies of up to 500 ms on task completion and error rate in five surgeons after completion of three different surgical tasks. RESULTS The(More)
BACKGROUND Anterior resection with total mesorectal excision (TME) is the standard method of rectal cancer resection. However, this procedure remains technically difficult. A robotic transanal approach could overcome some of these limitations. An initial laboratory experience with robotic transanal TME using a new designed port on human cadavers is(More)
MRP8, MRP14 and their heterodimer MRP8/14 (27E10 antigen) are myeloic related proteins which have been shown to have a major role in inflammatory and immunological responses. In the present study monospecific antibodies against MRPs were used to investigate immunohistochemically the distribution of these proteins in routinely processed bowel tissues from 23(More)
Robotically enhanced telemanipulation for totally endoscopic coronary artery bypass does not provide adequate tactile feedback, traction, or countertraction. The exposition of coronary target sites is difficult, the visual field is limited, and the epicardial stabilization may be troublesome. A fourth robotic arm for endothoracic instrumentation has been(More)
Robotically enhanced telemanipulation for totally endoscopic coronary artery bypass does not provide adequate tactile feedback, traction, or counter-traction. The exposition of coronary target sites is difficult, the visual field is limited, and the epicardial stabilization may be troublesome.

The USP bioassay for insulin currently used by industry and government requires a sc injection of insulin to rabbits and multiple assays of blood glucose. One hundred and forty-four rabbits are usually assayed, each assay taking at least 2 weeks. A bioassay for insulin is described. The new assay is based on a continuous monitoring of blood glucose and(More)
