  • SensiVida Medical Technologies to conduct clinical trials of minimally invasive allergy test system
    JULY 3, 2009--SensiVida Medical Technologies, Inc. (Henrietta, NY) says it has received clearance from the Western Institutional Review Board (WIRB; Olympia, WA), to begin clinical trials of its minimally invasive allergy test system. The microsystems-based optical technology promises to automate bio-sensing and data acquisition while minimizing patient discomfort. The platform targets other applications too, including glucose and cholesterol monitoring, and blood coagulation and TB testing....
  • Optical trap for on-chip virus and bacteria manipulation promising for cell sorting
    JULY 2, 2009--A new type of optical trap (optical tweezers) that enables on-chip manipulation of bacteria, viruses and other particles has the potential to create smaller, cheaper versions of the sophisticated equipment used to perform fluorescence-activated cell sorting (FACS). The trap is part of an integrated optofluidic platform; researchers at the University of California, Santa Cruz (UCSC) created it while working to devise new sensor technology for biomedical analysis....
  • Zeiss to intro SIM/PALM combination hi-res microscopy systems by year end
    JULY 1, 2009--Carl Zeiss MicroImaging GmbH (Jena, Germany) plans to launch a new high-resolution microscopy product line by the end of this year, to enable biomedical scientists to examine objects at maximum resolution. The new systems will combine high resolution structured illumination microscopy (HR-SIM) and photoactivated localization microscopy (PALM) to enable "new approaches and experiments in all disciplines of biomedical research," according to president and CEO Ulrich Simon....
  • Laser-generated "lenses" could enable recording of molecular dynamics
    JUNE 30, 2009--A research team at the University of Nebraska-Lincoln has figured out a possible way to observe and record the behavior of matter at the molecular level. Working with Nobel laureate Ahmed Zewail of the California Institute of Technology (Pasadena, CA), they developed mathematical models to show that laser beams create ultra-high-speed "temporal lenses" that would be capable of making "movies" of molecular processes for biomedical research and other applications....
  • UV-based handheld commercial device proves able to detect anthrax accurately, reliably
    JUNE 29, 2009--Veritide Ltd. (Christchurch, New Zealand) says that new independent data confirm the accuracy of its Ceeker portable bacterial detection device in discriminating between anthrax and similar-looking hoax substances. The data show that in over two weeks of testing Ceeker accurately identified 100% of the anthrax samples used and was correct in 95% of tests involving hoaxes. The system aims to help front-line decision makers quickly and confidently validate bioterrorism threats....
  • Low level light therapy proves promising for Parkinson's treatment
    JUNE 26, 2009--Low level light therapy (LLLT) holds potential for improving neuronal cell function in patients with Parkinson's disease (PD), according to a new study from the University of Virginia Health System. The study showed that a brief treatment with a 810 nm low level, NIR laser increased for two hours the velocity of mitochondrial movement in cells taken from patients with sporadic PD, speeding it to levels comparable to cells from a disease-free, age-matched control group....
  • Fujimoto outlines OCT progress, opportunity during Hounsfield memorial prize ceremony
    JUNE 25, 2009--MIT professor and optical coherence tomography (OCT) pioneer James Fujimoto became the fifth annual Hounsfield memorial lecturer at the UK's Imperial College London Imaging Sciences Centre earlier this month. The annual event, designed to recognize the contribution of Sir Godfrey Hounsfield to medical imaging, is meant to showcase a world-leading researcher and review developments in imaging science. As part of the event, Fujimoto was presented with the 2009 Hounsfield medal....
  • UK-based OCT developer Michelson opens US office
    JUNE 24, 2009--Michelson Diagnostics Ltd. (MDL; Orpington, UK) has opened a U.S. sales and support office in Fuquay-Varina, NC, in the Research Triangle vicinity of Raleigh-Durham. The office is headed by Kevin C. Oakley, Business Development Manager (US) for Michelson Diagnostics; it will act as a hub for growth of MDL's business in the field of optical coherence tomography (OCT) imaging....
  • Spectroscopy method shows potential for early detection, better treatment of Alzheimer's disease
    JUNE 23, 2009--Using minimally invasive biospectroscopy, Canadian scientists have been able to identify changes in oxidative stress (OS) levels in blood plasma, which may prove to be a useful biomarker in the early diagnosis of Alzheimer's disease. There is currently no accepted laboratory test for diagnosing Alzheimer's disease. The technology has been licensed to Molecular Biometrics, Inc. (Montreal, Canada)....
  • Studies report laser treatment reduces bruising, facilitates healing following cosmetic surgery
    JUNE 22, 2009--Candela Corp. (Wayland, MA) says that two studies have reported superior results on patients who benefited from the Candela Vbeam laser treatments for bruising resulting from cosmetic procedures. The studies concluded that the Vbeam pulsed-dye laser significantly expedited the healing process, improved outcomes, and provided greater overall patient satisfaction....
