Promoting Locomotor Learning with Spinal Direct Current Stimulation- Pilot Data (S28.005)
CONCLUSION: After interim analysis, we repowered the study and determined that 14 additional healthy volunteers per group will be needed, to achieve a statistical significance of 97.5 percent and a power of 0.80. Results gathered at this stage will allow us to further assess the effect of tDCS at different stages of locomotor learning, including online, offline, and total learning-- necessary for application in future neurorehabilitation trials involving patients with spinal cord injury and stroke.

Neural correlates of action recognition and object knowledge in neurodegenerative disease (P6.196)
CONCLUSIONS: Our results suggest that action recognition is supported by a distributed left lateralized functional network that exhibits dissociable roles. In particular, left mid-posterior temporal and inferior parietal areas seem critical for representation of the gestural component of action recognition while frontal inferior regions may support cognitive control requirements common to all 3 tests.Disclosure: Dr. santos has nothing to disclose.

Longer sleep linked to stroke
Conclusion This cohort study found that, overall, people who sleep for more than eight hours have a 46% increased risk of stroke. When analysed separately, there was no statistically significant association for men, but a much higher increased risk for women, of 80%. A major strength of the study is the number of potential confounding factors that the researchers tried to account for, including many cardiovascular risk factors. However, it did not account for other illnesses such as sleep apnoea or cancer, which may have had an effect on the amount of sleep and risk of stroke. In addition, the study is reliant on the i...

Inactivity 'twice as deadly' as obesity
Conclusion This study’s strengths included its large size and long follow-up period. Researchers also took into account a large number of factors (called confounders) that might have influenced the risk of death, such as diet, smoking history and alcohol intake, although it is still possible that both measured and unmeasured confounders influenced mortality rates. The study had one important limitation. It only measured people’s BMI (calculated by combining their weight and height) and their physical activity once, at the start of the study. It is quite possible that people’s BMI changed over time, and that this wou...

A Current Amplifier For Local Coil Pre-amplification Of NMR/MRI Signals
A Current Amplifier for Local Coil Pre-amplification of NMR/MRI SignalsDescription of Technology: The magnetic resonance imaging (MRI) systems are used for a variety of imaging application. The present invention discloses an improving MRI device and method by amplifying signals received by resonant NMR coils of MRI systems. It utilizes positive feedback from low-noise Field-Effect Transistor to amplify the signal current that can be coupled out to receiving loops positioned externally without loss in sensitivity. Therefore, the NMR coil can be flexibly positioned near internal tissues and used to develop high-resolution im...

Tomato extract's heart effects exaggerated
ConclusionThis study found that the blood vessels in people with cardiovascular disease who were taking statins dilated more after they were treated with a chemical called acetylcholine if they had been taking lycopene every day for two months, compared to those taking placebo pills.The lycopene tablet had no significant effect on any of the other outcomes the researchers looked at, and no effect in healthy volunteers, although it did increase lycopene levels in the blood.  Although impaired endothelial function is a known predictor of future heart disease, this is, at best, a surrogate outcome. It is no substitute for fo...

Tricks to Treatments: Sensory Tricks in Dystonia (P2.042)
CONCLUSIONS:We propose a new classification of ST,to include its variants, such as FT, MT, IT and rST. Wide range of prevalence and effectiveness of ST may reflect ambiguity of terminology and varying measures. More studies are needed to determine the interaction of deep brain stimulation and botulinum toxin with ST. Our research points to more benefit than harm for searching for, or even inducing, ST in patients with dystonia.Study Supported by:National Institutes of Health and the National Institute of Neurological Disorders and Stroke, and the the Dystonia Medical Research Foundation.Disclosure: Dr. Ramos has received p...

Tech titans gather to make winners of the 'Oscars of science' into instant millionaires
Silicon Valley hosts lavish ceremony for Breakthrough prize that aims to give scientists celebrity status and inspire interest in life's 'big questions'Silicon Valley has a tendency to tackle social ills with big ideas, its feisty startups revolutionising everything from healthcare to education. Now a handful of billionaire engineers have turned their attention to a social blight that affects their own kind: the lack of appreciation (and funding) for scientists.The second Breakthrough prize for life sciences is being awarded on Thursday at Nasa's Ames Research Centre in Mountain View, California, about a five-minute drive ...

ACE inhibitor use may be linked to kidney failure
Conclusion ACE inhibitors and ARAs are recognised as a potential risk factor for AKI in some patients. This particular study has tried to estimate the possible size of the problem, but its findings should be viewed with some caution. As the authors point out: some of the conditions these drugs are prescribed for are themselves a risk factor for AKI changes in hospital coding and better recognition of AKI could explain the rise in admissions an ageing population leads to both increased prescribing of these drugs and an increased risk for AKI increased use of these drugs may be a marker for increased use of other...
