Laser to help in root canal treatment
...t a direct laser, the but alternatively furnishes optical
energy to water, and the water particles themselves provide the cutting of dental hard tissue. Use of the Waterlase may reduce the need for anesthesia and fewer instruments can be used for treatment, according to Biolase. Postoperatively, it may red...
Airbags lessens oppressive eye injuries
..., while Level 4 described serious injuries such as optical
nerve damage and retinal detachment. The researchers found that 3.5 per cent of those involved in an accident where an airbag was deployed had an eye injury, compared to two per cent where an airbag was not involved. In fact, 25 per cent of all eye...
Testing for blood sugar levels made easier
...xas have discovered a new non-invasive test, using optical
coherence tomography, which will end the pain of pricking for diabetes patients. Optical Coherence Tomography uses advanced photonics and fiber optics to obtain images of tissues. It uses infrared light waves that reflect off the internal structures...
Gene-Nanoparticle Gene Transfer Is Better Than Viral Vector Transfer System
...ble to a viral vector," Bharali said. Using a new optical
fiber in vivo imaging technique (CellviZio developed by Mauna Kea Technologies of Paris), the UB researchers were able to observe the brain cells expressing genes without having to sacrifice the animal. Using this technique it is also possible to man...
Diabetes and heart attack diagnosis now made simple with twin magic
...tein markers released during a heart attack, using optical
measurements. What makes it extra special is that the needles play a dual role and complement each other. The tiny medical gadgets are expected to be constructed of cheap throw-away plastic which would not only make glucose testing simple and painl...
A Mirror Miracle!
... The team heads Roger and Leigh say," getting the optical
properties of mirror rights is crucial, light only passes easily through the skin over a tight range of infrared wavelengths but slicon surfaces dont reflect well at these wavelengths. And if the mirror was highly polished it would quickly loose its ...
