Life stressors trigger neurological disorders, researchers find

Life stressors trigger neurological disorders, researchers find

When mothers are exposed to trauma, illness, alcohol or other drug abuse, these stressors may activate a single molecular trigger in brain cells that can go awry and activate conditions such as schizophrenia, post-traumatic stress disorder and some forms of autism. Until now, it has been unclear how much these stressors have impacted the cells of a developing brain. Past studies have shown that when an expectant mother exposes herself to alcohol or drug abuse or she experiences some trauma or illness, her baby may later develop a psychiatric disorder, including some forms of autism or post-traumatic stress disorder, later in life.

Researchers rethink ‘natural’ habitat for wildlife

Protecting wildlife while feeding a world population predicted to reach 9 billion by 2050 will require a holistic approach to conservation that considers human-altered landscapes such as farmland, according to Stanford researchers. Continue reading

Multitarget TB drug could treat other diseases, evade resistance

Multitarget TB drug could treat other diseases, evade resistance

A drug under clinical trials to treat tuberculosis could be the basis for a class of broad-spectrum drugs that act against various bacteria, fungal infections and parasites, yet evade resistance, according to a study by University of Illinois chemists and collaborators. Led by U. Continue reading

Eavesdropping on brain cell chatter

Eavesdropping on brain cell chatter

Everything we do — all of our movements, thoughts and feelings — are the result of neurons talking with one another, and recent studies have suggested that some of the conversations might not be all that private. Brain cells known as astrocytes may be listening in on, or even participating in, some of those discussions. Continue reading

Synapses: stability in transformation

Synapses: stability in transformation

Synapses are the points of contact at which information is transmitted between neurons. Without them, we would not be able to form thoughts or remember things. Continue reading

Fighting neuroblastomas by blocking DNA replication, repair

Fighting neuroblastomas by blocking DNA replication, repair

Neuroblastoma is one of the deadliest childhood cancers, accounting for 15 percent of pediatric cancer deaths. For patients with high-risk neuroblastomas, the five-year survival rate is 40 to 50 percent even with the most rigorous treatments available today Continue reading

MRI pinpoints region of brain injury in some concussion patients

MRI pinpoints region of brain injury in some concussion patients

Researchers using information provided by a magnetic resonance imaging (MRI) technique have identified regional white matter damage in the brains of people who experience chronic dizziness and other symptoms after concussion. The findings suggest that information provided by MRI can speed the onset of effective treatments for concussion patients. The results of this research are published online in the journal Radiology Continue reading

Experimental blood test spots recurrent breast cancers, monitors response to treatment

Experimental blood test spots recurrent breast cancers, monitors response to treatment

Johns Hopkins Kimmel Cancer Center investigators report they have designed a blood test that accurately detects the presence of advanced breast cancer and also holds promise for precisely monitoring response to cancer treatment. Continue reading
