Evaluating Disease Biomarker Reliability
June 6, 2013 5:59 pm | by Arizona State University | News | CommentsThis year some 232,340 new cases of invasive breast cancer will be diagnosed in women. Some of these patients will succumb to the disease, while others survive. Part of the enormous disparity in outcome has to do with the differing ways diseases like cancer affect individuals based on various factors. According to new research, how we study an illness can also depend on a feature of the disease itself – one known as heterogeneity.
Anesthesia Effects Depend on Age of Neurons, Not Patient
June 6, 2013 11:07 am | News | CommentsAs pediatric specialists become increasingly aware that surgical anesthesia may have lasting effects on the developing brains of young children, new research suggests the threat may also apply to adult brains. Researchers recently reported that testing in laboratory mice shows anesthesia’s neurotoxic effects depend on the age of brain neurons– not the age of the animal undergoing anesthesia.
The Fight Against Genome Parasites
June 5, 2013 10:23 am | News | CommentsIn the gonads of animals, genome parasites, such as transposons, pose a serious threat to evolutionary fitness. To protect genomic integrity, animals evolved the so-called piRNA pathway to silence the deleterious transposons. Researchers have now identified almost 50 genes that play important roles in the piRNA pathway of the fruit fly Drosophila melanogaster.
Neuron Circuits Overexcited in Fragile X Brains
June 4, 2013 10:58 am | News | CommentsThe genetic malady known as Fragile X syndrome is the most common cause of inherited autism and intellectual disability. Brain scientists know the gene defect that causes the syndrome and understand the damage it does in misshaping the brain's synapses, but how this abnormal shaping of synapses translates into abnormal behavior is unclear. Now, researchers believe they know.
