Regeneration After Spinal Cord Injury

... injured patients. The result would be a return of functional activity. John Houle, Ph.D., is Professor of Neurobiology and Anatomy at Drexel University College of Medicine in Philadelphia. Dr. Houle, who is the senior communicating author in the co-authored study, has demonstrated in a lab animal how a nerve...

New Technique Identifies Unknown Genetic Mutations That Can Cause Cancer

...mics, the study of proteins. "We decided this more functional assay would get us to the disease-causing genes more rapidly," said Druker, who has been studying a group of cell-signalling proteins called tyrosine kinases for 20 years. Tyrosine kinases play a key role in many cancers. In healthy cells, they hel...

Decline in Concentration, Decision-Making and Problem-Solving

...re worsening," he says. Awareness of a patient's functional decline informs neurologists what areas of the brain are being affected as mild cognitive impairment progresses to Alzheimer's: the medial temporal lobe is affected as memory declines, and then the frontal regions of the brain are affected as executi...

Adam Godzik, Ph.D., is Professor and Director of the Bioinformatics and Systems Biology Program at the Burnham Institute for Medical Research. Yuzhen Ye, Ph.D., and Piotr Cieplak, Ph.D., are Research Assistant Pro...

Treatment of Spinal Cord Injury with Embryonic Stem Cells

...importantly, while the treatment did not help with functional recovery, it also did not impair it. Upon further examination, the scientists found no damage to the tissues surrounding the spinal cord indicating that the transplantation had not caused any damage to the animals. "Our biggest safety concern was t...

Men's Health - Prevention is the Key

... "Perhaps one reason for this is that men have a functional view of their bodies - many won't get help unless something actually goes wrong," said Dr Haikerwal. Young men in particular are reluctant to see their family doctor, but Dr Haikerwal said it is just as important for them to have regular check-ups....

Obsessive-Compulsive Disorder Is Familial

..., but also because of previous studies that show a functional link between glutamate and OCD. Brain imaging and spinal fluid studies have shown differences in the glutamate system between OCD patients and healthy volunteers, including in areas of the brain where the EAAC1 protein is most common. "Taken togeth...

Smoking Increases The Risk Of Rheumatoid Arthritis In Women

...t has the potential to cause joint destruction and functional disability. The authors base their findings on a comparison of 115 postmenopausal women with the disease and 466 women without. All the women were taking part in the Iowa Women's Health Study, a long term research project tracking participants' l...

Triple-Monitoring System To Monitor Heart Viability During Surgery

...ers together reveal early and small changes in the functional state of the heart tissue, and their exact location. This gives vital information to the surgeon on the extent of tissue damage and the time he has available to complete the procedure. A Lithuanian-led project, VIACORTIS brought together the Biom...

Understanding the Effects of Sleep Deprivation on Decision-Making

...ze lists of nouns. Drummond and his team also used functional magnetic resonance imaging in the morning and evening to map the brain's reaction. The imaging technique looks at oxygen use in the brain, so whatever part of the brain is being used, it needs more oxygen. "The brain is a system, a network of area...

Appearance Of Facial Scars Improved By Botulinum Toxin

...ssner. "In general, we know that scars can cause functional problems -- they can interfere with eye closure, talking and eating," he says. "They also can have a deep psychological impact. For patients who have accidents that produce significant scarring, their lives can be profoundly changed. They can become ...

Cellular System Causing Destruction Of Faulty Proteins In Cystic Fibrosis Identified

...roteins and thereby enables some of it to assume a functional shape. The trash collectors newly identified by the Cyr group are two different ubiquitin ligases, proteins that specifically recognize misshaped regions of CFTR and tag them with a degradation signal known as ubiquitin. The ubiquitin tag tells th...
