Robotic surgical platforms were first developed with telesurgery in mind. Conceptualized by NASA and the military to provide
surgical expertise to remote locations, some telesurgical success has been documented, but progress has been held back by
communication bandwidth limitations. Telepresence surgery, where the surgeon is in proximity to the patient but is provided
with an ergonomic console equipped with three-dimensional vision and autonomous control of wristed laparoscopic surgical instruments
and energy sources, has shown efficacy first in cardiac and then urologic cancer surgery. Interest is currently focused on
the application of this technology in the field of gynecology, with techniques being described to perform simple hysterectomy,
myomectomy, tubal anastomosis, and pelvic reconstruction procedures. This article will review the application of robotic-
and computer-assisted surgery in the specialty of gynecologic oncology. 相似文献

Corneal disease is the most common cause of bilateral blindness in the world. Visual loss in this condition is often due to changes in morphology and function of the corneal epithelial surface. Corneal disease-1 (corn1) and corn1(2J) are spontaneous mouse mutants that develop irregular thickening of the corneal epithelium, similar to that observed in human corneal surface disease. These autosomal-recessive mutations cause an increase in the rate of proliferation of the corneal epithelial cells. Here, we report that the phenotypes in both mutants are caused by mutations within the destrin gene (also known as actin-depolymerizing factor). By positional cloning, we identified a deletion encompassing the entire coding sequence of the destrin gene in corn1 mice, and a point mutation (Pro106Ser) in the coding sequence of destrin in corn1(2J) mice. In situ analysis showed that destrin is highly expressed in the corneal epithelium. Consistent with the cellular roles for destrin, an essential regulator of actin filament turnover that acts by severing and enhancing depolymerization of actin filament, we observed that the corn1 mutations increased the content of filamentous actin in corneal epithelial cells. Our results suggest an in vivo connection between remodeling of the actin cytoskeleton and the control of cell proliferation, and a new pathway through which an aberrant actin cytoskeleton can cause epithelial hyperproliferation. 相似文献
