Another local UCSD researcher, nanoengineering professor Joseph Wang, said he envisions a system where the body’s glucose levels would automatically trigger nanodevices capable of administering insulin.
Toxicity still presents challenges, he said, although he envisions “many exciting opportunities and applications which are limited only by our imagination.”
Trey Ideker, who holds posts in the schools of medicine and engineering at the University of California at San Diego, has found in laboratory tests that some limited exposure to oxidants may equip cells to better withstand larger exposures. His work, if borne out in humans, could have all kinds of implications for our understanding of aging and disease.Read the original press release, by Debra Kain, here.
Surgeons at UC San Diego Medical Center are pioneering non-invasive surgical procedures that eliminate the need to open a patient’s abdominal wall—innovations that speed recovery time and significantly reduce pain for abdominal surgeries, such as gall bladder removal. Instead of cutting through the abdominal wall, surgeons deliver the camera, lights and surgical instruments by way of the natural openings in the patient’s body—the mouth, vagina or rectum. The surgery is called NOTES or Natural Orifice Translumenal Endoscopic Surgery.
The UC San Diego surgeons want a better camera for NOTES, and for that they turned to engineers from the Jacobs School and Calit2.The team just completed the first prototype, called SurgiCam. The new camera boasts auto-focus and optical zoom—a big improvement over the digital zoom in today’s surgical cameras. Optical zoom will give surgeons the ability to change the field of view and obtain some peripheral vision, explains electrical engineering professor Yuhwa Lo. Lo invented the fluid-filled lens that is at the heart of SurgiCam—a lens that incorporates elements of both fish eyes and eagle eyes. The camera also doubles as a microscope, which could improve surgeons’ ability to remove cancer tissue.
