MRI-based cancer detection technique could replace biopsies

By - March 30, 2015 2 Pictures
While non-invasive imaging technologies, such as mammograms or CT scans, are capable of detecting tumors, identifying whether they are malignant or benign usually involves getting out the scalpel and conducting a biopsy. Now researchers at Johns Hopkins University have developed a technique that uses magnetic resonance imaging (MRI) to noninvasively detect cancerous cells, offering the potential of supplementing biopsies or maybe one day replacing them altogether.

Nanoparticles help wounds to heal 50 percent faster

By - March 30, 2015 2 Pictures
An experimental nanoparticle therapy cuts in half the time wounds take to heal compared to natural healing. The therapy has already been tested successfully in mice and will soon be tried on pigs, whose skin is similar to that of humans. If it reaches clinical use in humans, this sort of nanoparticle therapy could be used to speed healing of surgical incisions, chronic skin ulcers, and everyday cuts and burns and other wounds.

Magnetic nanoparticles open blood-brain barrier for delivery of therapeutic molecules

By - March 26, 2015 1 Picture
The blood-brain barrier is a highly selective semipermeable barrier running inside almost all vessels in the brain that lets through water, some gases and a few other select molecules, while preventing potentially toxic elements in the blood from entering the brain. Researchers from the University of Montreal, Polytechnique Montréal, and CHU Sainte-Justine say that currently 98 percent of therapeutic molecules are also blocked by the barrier, but they have developed a technique using magnetic nanoparticles that opens the door for such molecules, thereby also opening the door to new treatments for brain diseases.

Scientists create functioning "mini-lungs" to study cystic fibrosis

By - March 25, 2015 2 Pictures
Researchers at the University of Cambridge have grown functional "mini-lungs" using stems cells derived from the skin cells of patients with a debilitating lung disease. Not only can the development help them in coming up with effective treatments for specific lung diseases like cystic fibrosis, but the process has the potential to be scaled up to screen thousands of new compounds to identify potential new drugs.

Saccharin could sweeten the deal for cancer-fighting drugs

By - March 23, 2015 1 Picture
Whether it be advice from a dentist or preparing their body for beach season, there's a host of reasons people might reach for an artificial sweetener rather than sugar – though its cancer-fighting properties are unlikely to be one of them. But new research shows that the common sugar substitute known as saccharin could hamper the growth of particular cancers, with scientists claiming it could form the basis for new kinds of drug treatments.
