Research team identifies new Alzheimer's gene

... may eventually allow us to improve our ability to diagnose Alzheimer’s disease, even before it strikes” To date, the most significant gene found to predispose an individual to late onset Alzheimer’s (LOAD) has been APOE4. In this latest study, researchers from seven organizations contributed to the genome...

Brain holds clues to bipolar disorder

... illness and have the potential to help clinicians diagnose bipolar disorder earlier and more efficiently. Dr. Phillips also will present data illustrating how imaging can be used to identify biomarkers and how these markers can help clinicians determine which patients will respond best to certain treatments....

Catching cancer's spread by watching hemoglobin

...e technique convenient and powerful for helping to diagnose diseases such as melanoma, the deadliest form of skin cancer. The technique can image blood vessels up to a millimeter below the surface. Looking at blood vessels just below skin growths would be very useful for distinguishing between malignant and b...

Novel system developed to turn data into real-time, interactive 3-D images

...ns have become the primary tools physicians use to diagnose disease and make recommendations for effective treatment. New, innovative data display technology developed at Kent State University will provide doctors with a dramatically improved ability to evaluate medical images that are commonly used. This ...

Dinosaur hearing, listening to muscle noise, quieter cubicles

Sandia researchers take new approach to studying how cells respond to pathogens

...nding the early steps could lead to better ways to diagnose and stop disease before there are symptoms and development of more effective therapeutics. Most existing research into how immune cells respond has been done by looking at large cell populations. The Sandia researchers say information gathered fro...

Red flag for repetitive stress injuries identified for first time in humans

...rofessions. Currently, healthcare providers can diagnose repetitive motion injuries (RMI) based only on physical examination findings and the symptoms reported by the patient. Typically, RMI sufferers don't experience symptoms of pain until the damage has begun. So the researchers' main goal has been fi...

Gene tests and brain imaging reveal early dementia

...e years later. "It's surprisingly difficult to diagnose Alzheimer's with any certainty, but things are made easier if you know who runs the greatest risk," she says. "If genetic mapping, MRI and cognitive tests all suggest approaching Alzheimer's, it might be an idea to start a course of treatment." ...

Scientists create dual-modality microbeads to improve identification of disease biomarkers

...ve techniques that can find a specific molecule to diagnose this disease," explained Nie. "Our technique could also be used to monitor therapeutic response. For example, if the viral level decreases in samples taken at later dates, then we know the drug is probably working." This new technology allows the ...

Satellites shed light on global warming

...l variables which, when determined globally, helps diagnose the state of the Earth’s climate system. Professor David Llewellyn-Jones, Head of Earth Observation Science at the University of Leicester, UK, outlined the importance of SST data at the symposium. Tracking SST over a long period is arguably the ...

New study aims to stop sepsis in its tracks

... establish the first set of standard procedures to diagnose and treat sepsis in emergency departments. The National Institute of General Medical Sciences (NIGMS), part of the National Institutes of Health, launched the project this month with a grant totaling more than $8.4 million over five years. Derek C...

MRSA toxin acquitted: Study clears suspected key to severe bacterial illness

... of this toxin in disease, they could more quickly diagnose serious cases and develop effective treatments. In addition to observing the destruction of human white blood cells regardless of whether PVL was present, the researchers also used mouse models to learn that CA-MRSA strains are just as pathogenic ...

Protein 'fingerprint' in spinal fluid could spot Alzheimer's disease

...isease test that patients and doctors could use to diagnose illness and guide treatment is the ultimate goal. But the finding has important implications for current Alzheimer's research, as well. "You might have a promising treatment for the disease, but how can you know for sure that it's impacting on the...

Silver bullet: UGA researchers use laser, nanotechnology to rapidly detect viruses

...hat previous attempts to use Raman spectroscopy to diagnose viruses failed because the signal produced is inherently weak. But UGA physics professor Yiping Zhao and UGA chemistry professor Richard Dluhy experimented with several different metals and methods and found a way to significantly amplify the sig...
