Odor identification tests may help scientists track the evolution of the disease in persons at risk By the time you start losing your memory, it`s almost too late. That`s because the damage to your brain associated with Alzheimer’s disease (AD) may already have been going on for as long as twenty years. Which is why...

New terahertz imaging approach could speed up skin cancer detection
Researchers have developed a new terahertz imaging approach that, for the first time, can acquire micron-scale resolution images while retaining computational approaches designed to speed up image acquisition. This combination could allow terahertz imaging to be useful for detecting early-stage skin cancer without requiring a tissue biopsy from the patient. Terahertz wavelengths fall between microwaves...

Data Mined Insurance Records Point to Interesting Disease Relationships
Data about who has what disease holds a lot of clues about the diseases themselves and their causes. Researchers at the University of Chicago undertook a data mining effort to figure out what genetic and environmental patterns that a few dozen common diseases share with each other. The team gathered data from insurance claims related...

New malaria analysis method reveals disease severity in minutes
Red blood cells become less deformable as they undergo heme-induced oxidative stress caused by malaria parasites. Left untreated, malaria can progress from being mild to severe — and potentially fatal — in 24 hours. So researchers at the University of British Columbia developed a method to quickly and sensitively assess the progression of the mosquito-borne...

System creates 3-D images of tissue samples without conventional lenses
Hologram technology developed at UCLA could lead to improved diagnoses of chronic diseases in remote areas Ozcan Research Group/UCLARendering of a lens-free holographic microscope that uses a silicon chip and computer algorithms to create 3-D images of tissue samples. Anew system developed by UCLA researchers could make it easier and less expensive to diagnose chronic...

Cancer detection with sugar molecules
Like a spaceship, the complex sugar molecule (coloured) lands exactly on the tumor protein galectin-1, which here looks like a meteorite and is shown in black and white. Galectins are a family of proteins that have become a promising source of cancer research in recent years. A representative thereof is galectin-1. It sits on...

Blood test uncovers hidden diseases
Sufferers of rare mitochondrial disease have new hope with a new method developed at the University of Sydney. The method provides a diagnosis within weeks instead of months or years through a simple blood sample. Mitochondrial diseases are rare and hard to diagnose. They can affect any organ, at any age and are often ‘hidden’...

New blood test may transform the way cancer is monitored and treated
Stanford University scientists have described a new type of test that can detect genetic mutations in minute amounts of DNA released from cancer cells into the blood. The test, which is called single color digital PCR, requires only a fraction of a tube of blood and can detect as few as three mutation-bearing molecules in...

Automated measure of nighttime oxygen levels could speed diagnosis of sleep apnea
Simple, inexpensive test could help identify sleep apnea in children who snore. Computer analysis of oxygen levels in the blood during sleep could — by itself – provide an easy, relatively inexpensive and sufficiently reliable way to determine which children who snore habitually could benefit from a diagnosis and treatment for obstructive sleep apnea. This approach...

Fast, Noninvasive Technique For Probing Cells May Reveal Disease
The stiffness or elasticity of a cell can reveal much about whether the cell is healthy or diseased. Cancer cells, for instance, are known to be softer than normal, while asthma-affected cells can be rather stiff. Determining the mechanical properties of cells may thus help doctors diagnose and track the progression of certain diseases. Current...
