The answer to the age-old mystery of the evolutionary origins of vertebrate eyes may lie in hagfish, according to a new study by biologists at the University of Alberta. Hagfish eyes can help us understand the origins of human vision by expanding our understanding of the early steps in vertebrate eye evolution, explained lead author Emily Dong, who conducted the research during her graduate studies with Ted Allison, a professor in the Faculty of Science and member of the U of A s Neuroscience and Mental Health Institute. Our findings solidify the hagfish s place among vertebrates and open the door to further research to uncover the finer details of their visual system.
Preventing seizures after head injury could slow or prevent the onset of dementia
Blocking seizures after a head injury could slow or prevent the onset of dementia, according to new research by University of Alberta biologists.
Traumatic brain injury is a major risk factor for dementia, but the reason this is the case has remained mysterious. Through this research, we have discovered one important way they are linked namely, post-injury seizures.
Ted Allison, Co-Author and Professor, Department of Biological Sciences, Faculty of Science, University of Alberta There is currently no treatment for the long-term effects of traumatic brain injury, which includes developing dementia, added lead author Hadeel Alyenbaawi, who recently completed her PhD dissertation on this topic in the Department of Medical Genetics in the Faculty of Medicine & Dentistry.
EDMONTON People who have suffered a traumatic brain injury are at a higher risk of developing dementia, but new research from the University of Alberta shows a way to delay the disease. A team of U of A biologists say that preventing seizures is the key and can improve people s quality of life in the short and long term. “Dementia is devastating for patients and families, and it is growing in prevalence in our aging demographics,” professor and co-author Ted Allison said in a written release. “These findings open the exciting possibility of refining the anti-epileptic treatments to be a prevention not only of seizures, but also dementia.”
authorized. secondly? this goes to the supreme court, ted aolson has the experience t argue before the supreme court. digenova is the yin to the yang. they ll try to lit zbigate this fox news and breitbart. if you remember, when jim comey confronted the bush administration at the bedside of then attorney john ashcroft over nsa warrantless wiretapping, who did jim comey call to be his witness in his conversation with the president in the oval office? had ted olson, solicitor general of the united states at the time. what great memory you have, jeremy bash! that s a great detail. ted allison s former wife was killed on 9/11, i should point out. she was in one of the planes that took off from dulles airport so the plane that went into the pentagon, i believe. so there is a whole mix of feelings about ted olson but a lot of us know him very, very well. certainly the supreme court justices know him very well and personal relationships matter in this town as will, of course,
