Shining light on pancreatic cancer
...ue that otherwise are undetectable by conventional microscopic examination," said Northwestern engineer Vadim Backman, an NSF CAREER awardee who led the development of the new technologies and is a co-author on the research. By studying tissue extracted from an area adjacent to the pancreas, the researchers we...Brightening prospects of using fluorescent nanotubes in medical applications
... Nanotubes should work as well as gold clusters as microscopic blow torches while their fluorescence should make them easy to locate. At least that is the hypothesis the researchers hope to test....Aluminum foil lamps outshine incandescent lights
...er, microcavity plasma lamps produce the plasma in microscopic pockets and require no ballast, reflector or heavy metal housing. The panels are lighter, brighter and more efficient than incandescent lights and are expected, with further engineering, to approach or surpass the efficiency of fluorescent lighting. ...High pretreatment PSA velocity predicts worse outcome
...oped various algorithms, using such factors as the microscopic features of the tumor (i.e., Gleason score), size, spread of the disease, and location of disease, to determine prognosis. However, recent trends suggest that these factors are not effective and that better indicators are needed. Calculating PSA velo...Mid Sweden University leads development of digital color x-rays

The readout electronics for each pixel in the cameras picture sensor must be squeezed into an area of 55 x 55 m, and whats more be x-ray safe. The Mid Sweden University researchers have solved these design problems. Furthermore, they have...Gel derived from a patient's own blood may help promote wound healing

However, when the count of platelets in the gel was more than six times the count of platelets in the individuals blood vessels, new tissue appeared three ...Veterans exposed to Agent Orange have higher rates of prostate cancer recurrence
...ave disease recurrence, Dr. Terris points out that microscopic cancer cells can migrate out of the area before surgery, becoming detectable later when they start pushing PSA levels back up. In fact, following any type of prostate cancer treatment, men routinely get PSA levels checked for the rest of their live...UC Irvine researchers reveal first images of brain changes associated with memory

"Our next step is to do electron microscopic analysis of clogged standard and anti-reflux stents to evaluate the role of reflux of intestinal contents in stent clogging," Dua says. "We also hope to look at other uses for this type of stent."...NeuroArm: Navigating the future of surgery
