Heartbeat Vibrations Power Pacemakers
Though pacemakers require only small amounts of energy (about 1 millionth of a Watt), their batteries have to be replaced periodically, which means multiple surgeries for patients...

Brain Blood Flow And Oxygen Monitored By First-Of-Its-Kind Head Patch
A research team led by investigators at Mayo Clinic in Florida has found that a small device worn on a patient's brow can be useful in monitoring stroke patients in the hospital. The device measures blood oxygen, similar to a pulse oximeter, which is clipped onto a finger...

Device Provides A Platform For Viewing Cancer Cells And Other Macromolecules In Dynamic, Life-Sustaining Liquid Environments
A photograph of a polar bear in captivity, no matter how sharp the resolution, can never reveal as much about behavior as footage of that polar bear in its natural habitat. The behavior of cells and molecules can prove even more elusive...

Protein Structures Offer Clues To Breast Cancer, Alzheimer's Treatment, Prevention
Using some of the most powerful nuclear magnetic resonance equipment available, researchers at the University of California, Davis, are making discoveries about the shape and structure of biological molecules - potentially leading to new ways to treat or prevent diseases such as breast cancer and Alzheimer's disease...

Portable Recording Of Vital Signs Via "Life And Activity Monitor"
Researchers have developed a type of wearable, non-invasive electronic device that can monitor vital signs such as heart rate and respiration at the same time it records a person's activity level, opening new opportunities for biomedical research, diagnostics and patient care...

Alzheimer's-Related Protein In Brains Of Healthy Adults May Shed Light On Earliest Signs Of Disease
Researchers from the Center for Vital Longevity at the University of Texas at Dallas and UT Southwestern Medical Center have completed a large-scale neuroimaging study of healthy adults from age 30 to 90 that measured beta-amyloid protein - a substance whose toxic buildup in the brain is a diagnostic marker for Alzheimer's disease...

Are CT Scans For Dizziness In ER Cost-Effective?
Henry Ford Hospital researchers have found that conducting CT scans in the emergency department (ED) for individuals experiencing dizziness may not be cost effective. The researchers discovered that less than 1% of CT scans carried out in the ED showed a more serious underlying cause for dizziness (stroke or intracranial bleeding), which required intervention...

Medical Device Industry And FDA Reach Provisional Fees Agreement
An agreement, in principle, regarding proposed recommendations for the new reauthorization of a medical device user fee program, has been agreed by the FDA and the Medical Device Industry. If the recommendations go through, the FDA would be authorized to collect $595 million from the medical device industry in user fees for a five-year period, with adjustments according to annual inflation rates...

Researchers Develop Novel Drug Delivery System
Long duration, controllable drug delivery is of wide interest to medical researchers and clinicians, particularly those seeking to improve treatment for patients with chronic pain or to prevent cancer recurrence after surgery...

Liquid Lasers May Better Detect Genes Linked To Cancer
Using a liquid laser, University of Michigan researchers have developed a better way to detect the slight genetic mutations that might predispose a person to a particular type of cancer or other diseases. Their results are published in the current edition of the German journal Angewandte Chemie. This work could advance understanding of the genetic basis of diseases...

Brain Activity Can Show Scientists Words We Are "Thinking"
A study conducted by researchers at the University of California, Berkley, and published in PLoS Biology reveals neuroscientists' new breakthrough research on how they will be able to understand the thoughts of patients without actually hearing them speak. This will be incredibly helpful when treating patients who are unable to speak after strokes, paralysis, or even possibly during comas...

Decoding Brain Waves Could Lead To Communication With Patients Unable To Speak
Neuroscientists may one day be able to eavesdrop on the constant, internal monologs that run through our minds, or hear the imagined speech of a stroke or a locked-in patient with inability to speak, according to researchers at the University of California, Berkeley...

Improved Detection Of Colorectal Cancer By Flexible Sigmoidoscopy
Repeated screening by flexible sigmoidoscopy (FSG) increased the detection of colorectal cancer or advanced adenoma in women by one-fourth and in men by one-third, according to a study published Jan. 31 in the Journal of the National Cancer Institute...

Research At Rice University Leads To Nanotube-Based Device For Communication, Security, Sensing
Researchers at Rice University are using carbon nanotubes as the critical component of a robust terahertz polarizer that could accelerate the development of new security and communication devices, sensors and non-invasive medical imaging systems as well as fundamental studies of low-dimensional condensed matter systems...

Cyberknife Radiation Successful For Treating Tigeminal Neuralgia
A small study published online in the Journal of NeuroInterventional Surgery shows that a technique in which highly concentrated beams of radiation are used, known as Cyberknife, can relieve the stabbing pain of the facial nerve condition trigeminal neuralgia...
