Targeting selected amyloid-beta dimers in early stages of Alzheimer's disease
Date: Feb-21-2014Researchers studying peptides using the Gordon supercomputer at the San Diego Supercomputer Center (SDSC) at the University of California, San Diego have found new ways to elucidate the creation of the toxic oligomers associated with Alzheimer's disease.Igor Tsigelny, a research scientist with SDSC, the UCSD Moores Cancer Center, and the Department of Neurosciences, focused on the small peptide called amyloid-beta, which pairs up with itself to form dimers and oligomers.
Help for college-age women in abusive relationships - Smartphone App
Date: Feb-21-2014Women between the ages of 18 and 24 are at the highest risk for dating violence, according to the Centers for Disease Control and Prevention. However, these women are less likely than older adults to seek formal safety resources and instead look to peers or technology for help and advice.
How cognition works in the brain
Date: Feb-21-2014Keep this in mind: Scientists say they've learned how your brain plucks information out of working memory when you decide to act.Say you're a busy mom trying to wrap up a work call now that you've arrived home. While you converse on your Bluetooth headset, one kid begs for an unspecified snack, another asks where his homework project has gone, and just then an urgent e-mail from your boss buzzes the phone in your purse. During the call's last few minutes these urgent requests - snack, homework, boss - wait in your working memory. When you hang up, you'll pick one and act.
Genetically modified T cells induced complete remissions in 88 percent of advanced leukemia patients treated
Date: Feb-21-2014Investigators from Memorial Sloan Kettering Cancer Center have reported more encouraging news about one of the most exciting methods of cancer treatment. The largest clinical study ever conducted to date of patients with advanced leukemia found that 88 percent achieved complete remissions after being treated with genetically modified versions of their own immune cells. The results were published in Science Translational Medicine.

Switch identified that says it's time to sleep
Date: Feb-21-2014The switch in the brain that sends us off to sleep has been identified by researchers at Oxford University's Centre for Neural Circuits and Behaviour in a study in fruit flies.The switch works by regulating the activity of a handful of sleep-promoting nerve cells, or neurons, in the brain. The neurons fire when we're tired and need sleep, and dampen down when we're fully rested.'When you're tired, these neurons in the brain shout loud and they send you to sleep,' says Professor Gero Miesenböck of Oxford University, in whose laboratory the new research was performed.
Metabolism may play a role in epilepsy
Date: Feb-21-2014Researchers from the Franciscan University of Steubenville, Ohio are exploring a possible link between metabolic defects and seizures. They determined that diet could influence susceptibility to seizures, and they have identified a common diabetes drug that could be useful in treating disorders such as epilepsy.Dr. Daniel Kuebler, the principal investigator behind the experiment, and his lab made the connection by measuring fruit fly movement with inexpensive web-cams.
New smartphone apps 'detect epilepsy and improve stroke care'
Date: Feb-21-2014In these modern times, there is practically a smartphone app for all aspects of life. Now, new research has detailed two new apps that could help people detect epileptic seizures and receive better treatment for stroke.The two new studies will be presented at the American Academy of Neurology's 66th Annual Meeting in Philadelphia, PA, in April.For the first study that looks at the creation of the epilepsy app, the research team analyzed 67 people with the condition.

Genetic screening could identify risk of advanced prostate cancer
Date: Feb-21-2014New research from the Institute of Cancer Research in the UK suggests that screening men with a family history of prostate cancer for certain gene mutations could identify those who are at increased risk of aggressive forms of the disease and need lifelong monitoring.To reach their findings, recently published in The British Journal of Cancer, the investigators analyzed blood samples from 191 men with prostate cancer.Using "second-generation" DNA sequencing technologies, the researchers assessed 22 different known cancer genes at the same time.
