Application Of Innovative Laser Research Could Lead To Earlier Bone Disorder Diagnosis
A new laser technique that could lead to bone disorders being diagnosed earlier is to be tested in a hospital for the first time. The study, which it"s hoped will pave the way for future clinical trials, will apply a revolutionary approach known as SORS (Spatially Offset Raman Spectroscopy), to examine specific substances in non see-through surfaces deeper than has previously been possible, without damaging the surface. The research team hope ultimately that the method can be used both to detect and screen for early signs of diseases such as osteoarthritis and osteoporosis.

Stroke Patients Less Likely To Meet Treatment Goals Than Heart Disease Patients
A majority of high-risk stroke patients are less likely to meet clinical treatment targets to prevent repeat stroke or heart attacks compared to those with heart disease, suggesting the need to examine new therapeutic strategies, according to a study led by St. Michael"s Hospital neurologist Dr. Gustavo Saposnik. What"s more, medical procedures or ongoing specialty care may improve patients" awareness and consequent treatment success.

People With Intellectual Or Developmental Disabilities Particularly Vulnerable To Effects Of Tobacco Use And Dependence
While tobacco use is an ongoing health hazard for the entire population, its consequences for people with developmental or intellectual disabilities can be especially severe. And the medical community often tends to overlook the tobacco-related burdens these people face. An extensive review of published research on this topic appears in the June edition of the journal Intellectual and Developmental Disabilities.

Erythropoietin Boosts Brainpower

Healthy young mice treated with erythropoietin show lasting improved performance in learning and other higher brain functions. Researchers writing in the open access journal BMC Biology tested the cognitive effects of the growth factor, finding that it improved the sequential learning and memory components of a complex long-term cognitive task. Hannelore Ehrenreich led a team of researchers from the Max Planck Institute of Experimental Medicine in Gç¶ttingen, Germany, who studied the mice. She said, "Erythropoietin has been in clinical use for over 20 years to treat patients with anemic conditions, ranging from renal failure to cancer. It has recently received attention for its apparent ability to improve cognitive function in people with schizophrenia and multiple sclerosis. Here, we sought to investigate erythropoietin"s effects in healthy mice". Ehrenreich and her colleagues tested the effects of erythropoietin on the ability of the mice to learn how to exploit an experimental set-up to receive sugared water. Over a series of learning stages, the mice were trained to get their treat by poking their noses into holes lit by LEDs, rather than into unlit holes, within a time limit. The mice that had been treated with recombinant human erythropoietin were significantly more likely to master the task than those that had not. According to Ehrenreich, "Treated mice showed superior performance in associative, operant and discriminant learning as well as in the initial training phases. Moreover, erythropoietin-treated mice demonstrated better task adaptation and higher performance stability". The researchers conclude, "Further untangling of molecular mechanisms of erythropoietin action on higher cognitive functions may ultimately open new avenues for prevention strategies and therapeutic interventions in neuropsychiatric diseases".
