A technique that can detect malarial parasite's waste in infected blood cells has been developed by researchers. "There is real potential to make this into a field-deployable system, especially since you don't need any kind of labels or dye. It's based on a naturally occurring biomarker that does not require any biochemical processing of samples" says one of the senior authors of a paper.

A laser-based method has been used to produce the first-ever set of images clearly and directly detailing how cocaine shuts down blood flow in the brain. This could help doctors and researchers better understand how drug abuse affects the brain, which may aid in improving brain-cancer surgery and tissue engineering, and lead to better treatment for recovering drug addicts.

Using functional near infrared spectroscopy, researchers showed differential brain activation patterns between people with multiple sclerosis (MS) and healthy controls. This is first MS study to examine brain activation using fNIRS during a cognitive task.

Xenon gas, used in humans for anesthesia and diagnostic imaging, has the potential to be a treatment for post-traumatic stress disorder and other memory-related disorders, researchers report. "We know from previous research that each time an emotional memory is recalled, the brain actually restores it as if it were a new memory. With this knowledge, we decided to see whether we could alter the process by introducing xenon gas immediately after a fear memory was reactivated," explained an author.

Premature babies are far more at risk than infants born at term of developing brain damage resulting in neurodevelopmental delay that may persist throughout their lives. A team of specialists in infant brain imaging has demonstrated that administering three doses of erythropoietin may help.

Algorithms to identify weak spots in tendons, muscles and bones prone to tearing or breaking have been developed by researchers. The technology, which needs to be refined before it is used in patients, one day may help pinpoint minor strains and tiny injuries in the body’s tissues long before bigger problems occur.

Dynamic nanoparticles (NPs) have been developed that could provide an arsenal of applications to diagnose and treat cancer. Built on an easy-to-make polymer, these particles can be used as contrast agents to light up tumors for MRI and PET scans or deliver chemo and other therapies to destroy tumors. In addition, the particles are biocompatible and have shown no toxicity.

A balance board accessory for a popular video game console can help people with multiple sclerosis (MS) reduce their risk of accidental falls, according to new research. Magnetic resonance imaging scans showed that use of the Nintendo Wii Balance Board system appears to induce favorable changes in brain connections associated with balance and movement.

Current X-ray examinations capture only 20 percent of cases of lung cancer, researcher say. With modern ultralow-dose CT, the radiologists hit the bull’s eye 90 per cent of the time.

A new device could soon be available to treat stroke more effectively. The ClotBust ER® fits on the head like a halo and delivers therapy to quickly bust clots that cause stroke. The ClotBust ER® has 16 transducers scattered around the inside -- designed to line up with the thin points in the skull: the temples and the foramen magnum in the base of the skull.
