Magnetic resonance imaging (MRI) is an imaging technique which physicians use for the diagnosis and treatment of medical conditions.

Lack of grey matter linked to schizophrenia and bipolar disorder

A research study led by scientists from the Gregorio Marañón University Hospital in Madrid and the Network of Centres for Biomedical Research in Mental Health Networks (CIBERSAM) shows that adolescents experiencing a first outbreak of psychosis have lower levels of grey matter in their brains than healthy teenagers. Strangely, this change was seen in patients suffering from various psychoses, including bipolar illness and schizophrenia.

Artificial antibody delivers nanoparticles to tumors

Antibodies that target epidermal growth factor receptor (EGFR) have proven themselves as potent anticancer drugs. Now, a team of investigators led by Shuming Nie, Ph.D., and Lily Yang, Ph.D., both at the Emory University School of Medicine and members of the Emory-Georgia Tech Nanotechnology Center for Personalized and Predictive Oncology, is aiming to capitalize on this targeting ability, using a modified anti-EGFR antibody to delivery nanoparticles into tumor cells.

Toxin-nanoparticle combo inhibits brain cancer invasion while imaging tumors

Working with a nanoparticle designed to target and image glioblastoma, a form of brain cancer, investigators at the University of Washington in Seattle have found that these same nanoparticles inhibit tumor cell invasion, one of the key events that leads to the metastatic spread of cancer. The investigators have also determined how the nanoparticles exert this potentially beneficial effect.

Biodegradable nanoprobe images new blood vessel growth

Angiogenesis, the growth of new blood vessels, plays a critical role in several chronic human diseases, including metastatic cancer. In fact, several new anticancer therapies are designed to starve tumors by shutting down angiogenesis, but the lack of a good assay for quantifying angiogenesis in the body has hampered the development of effective antiangiogenesis therapies.

Frontostriatal brain circuits play role in bulimia nervosa in women

Women with bulimia nervosa appear to respond more impulsively during psychological testing than those without eating disorders, and brain scans show differences in areas responsible for regulating behavior, according to a report in the January issue of Archives of General Psychiatry , one of the JAMA/Archives journals.

Alcohol consumption during pregnancy damages offspring's white matter - brain's connective network

One part of the prenatal brain that may be particularly sensitive to alcohol's effects is white matter, nerve fibers through which information is exchanged between different areas of the central nervous system.
