Incidents of young athletes collapsing during sports practice due to an undiagnosed heart condition are alarming, and have led some health care professionals to call for mandatory electrocardiogram (ECG) screenings before sport participation. Others, however, question the validity of such a mandate. A new study soon to be published in The Journal of Pediatrics examines the accuracy and effectiveness of pre-sport participation ECGs.Dr. Allison Hill and colleagues from Stanford University...

(Ivanhoe Newswire)--The sudden collapse of young athletes due to an undiagnosed heart condition is frightening and causing some to begin questioning professional mandates. Some health care professionals have begun calling for mandatory electrocardiogram (ECG) screenings for athletes prior to sports participation while others are challenging the validity of this mandate.Electrocardiogram screenings are a diagnostic tool that measures the electrical activity of the heart in detail....

Maxim Bazhenov and Giri Krishnan used computational model to study epileptic seizures at the molecular level; research could lead to novel therapeutics for seizure disorderResearchers at the University of California, Riverside have made a discovery in the lab that could help drug manufacturers develop new antiepileptic drugs and explore novel strategies for treating seizures associated with epilepsy "“ a disease affecting about two million Americans.Neurons, the basic building blocks of the...

Lost your keys? Your brain might be in a better state to recall where you put them at some times than at others, according to new research from UC Davis. A paper describing the work is published June 13 in the journal Proceedings of the National Academy of Sciences."It's been assumed that the process of retrieving a memory is cued by an external stimulus," said Charan Ranganath, professor at the UC Davis Center for Neuroscience and Department of Psychology. "But we found that...

Using a high-resolution single-molecule study technique, University of Illinois researchers have seen the very subtle differences between two branches of an important family of neurotransmitter-gated ion channels.Professor Claudio Grosman and research scientist Gisela Cymes published their work in the journal Nature.Nicotinic-type receptors are proteins embedded in the membranes of nerve and muscle cells that regulate activity. A neurotransmitter, such as acetylcholine, triggers a small...

(Ivanhoe Newswire) -- Through new technology scientists have a clearer understanding into the cellular mechanisms of neuronal networks. A new research has established a unique way of loading specific drugs onto a collection of electrodes and triggering its release into cultured neurons.Researchers at the University of Pittsburgh attempted to design an implant capable of detecting a number of neurological symptoms, including those associated with seizures, tiny electrodes are coated with a...

Tiny electrodes have been coated with a drug-loaded polymer in an attempt to design an implant capable of detecting a number of neurological symptoms, such as those associated with an epileptic seizure, and treating them simultaneously.In a study published today, 2 June 2011, in IOP Publishing's Journal of Neural Engineering, researchers have developed a novel technology to precisely modulate individual neurons in rats, allowing the molecular, neuronal, and circuit functions to be analysed...

According to new study in the American Journal of MedicineSudden cardiac death in young athletes who had not previously exhibited symptoms is a relatively rare yet tragic event. This occurs in around 60-80 young athletes annually in the United States. In the June 2011 issue of The American Journal of Medicine, researchers collected electrocardiograms and echocardiograms of 964 athletes at a single university and found that distinct ECG abnormalities were present in 10% and were more common in...

An essential component of animal nervous systems"”sodium channels"”evolved prior to the evolution of those systems, researchers from The University of Texas at Austin have discovered."The first nervous systems appeared in jellyfish-like animals six hundred million years ago or so," says Harold Zakon, professor of neurobiology, "and it was thought that sodium channels evolved around that time. We have now discovered that sodium channels were around well before nervous...
