61. New Bioimaging Technique Diffuses Light Inside Living Tissue 1/8/2015

    Researchers at Washington University in St. Louis have found a way to focus light deep inside tissues, a technology that may enable real-time optogenetic studies. Using a time-reversed ultrasonic encoding method, the non-invasive technique is the first to diffuse light inside a scattering medium that contains living tissue.

62. Fingertip Blood Sensor Could Speed Trauma Triage 1/8/2015

    Using an instrument typically found in physician’s offices, trauma surgeons have found a way to save time when making medical decisions. After an evaluation, the researchers determined that a device called the Pronto-7 Pulse CO-oximeter produces results with similar accuracy to traditional laboratory tests in as little as 40 seconds.

63. Using Nanoparticles To Increase Orthopedic Biocompatibility 1/8/2015

    In an effort to improve the compatibility of metal structures with bone, a team from the Research Center for Advanced Materials (Cimav) in Mexico is turning to nanotechnology. An in-depth study of the chemical composition and nanostructure of bone tissue is being paired with novel material fabrication to help provide Mexico with a domestically manufactured, cutting-edge technology.

64. India's Medical Device Regulations May Change In 2015 1/7/2015

    India’s ministry of health has proposed amendments to the country’s medical device and pharmaceutical laws that will be submitted to parliament for approval in 2015. The draft changes have been publicly released for comments. The new legislation was developed to more closely align India’s regulations with the European Medical Device Directives.

65. Self-Reporting Tool Enables Improved Monitoring Of Dementia 1/6/2015

    Researchers from Indiana University have developed a way to effectively monitor the progression of dementia from the home environment. The new method tracks a patient’s self-reported changes in mental state and accurately gives insight into how dementia may be changing over time — something that was previously only possible in an office- or hospital-based setting.

66. Synthetic Grafts May Lead To Off-The-Shelf ACL Implants 1/6/2015

    To repair torn ACLs, Northwestern University researchers are turning to synthetic implants. In an attempt to replace bone-patellar tendon-bone autografts, which are the current standard of care, the team is using braided polymers combined with calcium nanoparticles. In vivo results are promising and show the implants bonding to bone in a way that may translate into human studies.

67. Roche Ebola Test Authorized By FDA For Emergency Use 1/5/2015

    Emergency use authorization has been granted to Roche by the FDA for its LightMix Ebola Zaire rRT-PCR Test. The test requires whole blood samples and is run on the manufacturer’s large LightCycler 480 or cobas z 480 laboratory-based instruments. Providing results in about three hours, LightMix is designed for patients exhibiting symptoms of Ebola Zaire that may have epidemiologic risk factors — like travel history in high-risk regions.

68. New MRI Approach Could Detect Alzheimer's Disease Early 1/5/2015

    Early detection of Alzheimer’s disease may now be possible based on research from a Northwestern University team. Their new magnetic resonance imaging (MRI) technique has been used to detect the earliest stages of the disease in a living animal, well before symptoms typically appear.

69. Leveraging Electronics Manufacturing To Build Living Tissue 1/5/2015

    A new device that incorporates concepts from electronics manufacturing has been used to build tissue-like constructs. From cell-laden, tissue-engineered subunits, larger living aggregates have been assembled in a manner that resembles the pick-and-place automation used in electronics. Current work has led to assemblies with cell densities similar to natural tissues, and making organs could be the next step.

70. Novel Imaging Technique Could Provide Better Diagnostics For Colon Cancer 1/5/2015

    Illness has often been tied to bacterial disturbances in the human body. Recently, a new bacterial imaging technique has been applied by Johns Hopkins researchers in the study of colon cancer. The researchers discovered a correlation between colon cancer and the presence of dense clumps of bacteria in the ascending colon.
