Microsurgery Made More Accurate With Virtual Measuring Tool
...hrough wide openings, and operates with the aid of specially designed manipulators and viewing devices, to achieve minimal tissue destruction. Since inception of the concept, MIS techniques have revolutionized a broad range of surgical procedures and have had a major impact on patient safety and health care co...Genetic "Short Circuit" Leads To Cleft Palate
...h of their work has revolved around two strains of specially bred mice-one strain sensitive to steroid-induced clefting, the other strain resistant. Using these mice they have now pieced together a molecular explanation for cleft palate. The genetic circuit that they describe is similar to an old-fashione...Jefferson Scientists Find Potential Deadly Effects Of Two Missing Cancer-Suppressor Genes
...as Jefferson University, Philadelphia, studying specially bred "knockout" mice, have found that two genes that normally protect against cancer may play a greater role than previously suspected in female development. In the September issue of Nature Genetics , Richard Fishel, Ph.D., and pos...UW Smogmobile Offers Cleaner, Safer Alternative To Gas Or Electric Cars
...tank through a series of aluminum tubing coils and specially designed pipes. Engine exhaust and outside air are circulated around the coils and pipes to gradually warm up the nitrogen from a minus-320 F liquid to an ambient-temperature gas. The conversion from liquid to gas expands the volume of the nitrogen 7...Herpes-Based Gene Therapy Is Key To Promising Liver Tumor Vaccine
... great numbers of immune cells that have developed specially in response to the tell-tale proteins found on the surface of cancer cells. In theory, the sheer numbers of these cells should wipe out any stray cancer cells that escaped the surgeon's knife.

According to the researchers, the ability to work with these independent membranes that are uniform in size...
