Envelope for an Artificial Cell

By combining a nanoparticle that is readily visible in X-ray computed tomography (CT) scans with a molecule that targets tumor lymph vessels and other tumor tissues, a research team from the University of California, San Diego (UCSD) and the Sanford-Burnham Medical Research Institute has developed a new imaging agent that provides high-fidelity CT images of tumors and their edges. This work, led by Michael Sailor of UCSD and Erkki…

New Test Spots Early Signs of Inherited Metabolic Disorders

A team of scientists, led by researchers at the University of California, San Diego School of Medicine and Zacharon Pharmaceuticals, have developed a simple, reliable test for identifying biomarkers for mucopolysaccharidoses (MPS), a group of inherited metabolic disorders that are currently diagnosed in patients only after symptoms have become serious and the damage possibly irreversible.

The findings will be published online January 8 in the…

New Approach to Management of Overeating in Children

Overeating, whether in children or adults, often takes place even in the absence of hunger, resulting in weight gain and obesity.  Current methods to treat such overeating in youth focus on therapies that restrict what kids may eat, requiring them to track their food intake and engage in intensive exercise.

But for most children, such behavioral therapy techniques don’t work long term, according to Kerri Boutelle, PhD, associate professor of…

Hybrid GPS-Seismic System Aims to Accelerate Earthquake Hazard Response

Scripps Institution of Oceanography / University of California, San Diego

Japanese seismologists required approximately 20 minutes to accurately determine the full magnitude of last March's massive earthquake off Japan, precious moments for disaster response activation. Now scientists at Scripps Institution of Oceanography at UC San Diego are developing a next-generation detection system they believe could drastically shrink that assessment time down to two to three…

Old Drugs Find New Target For Treating Brain Tumor

Scientists at the University of California, San Diego School of Medicine and UC San Diego Moores Cancer Center, in collaboration with colleagues in Boston and South Korea, say they have identified a novel gene mutation that causes at least one form of glioblastoma (GBM), the most common type of malignant brain tumor. 

The findings are reported in the online edition of the journal Cancer Research.

Perhaps more importantly, the…

New Drug Combo Targets Multiple Cancers

Researchers at the University of California, San Diego School of Medicine and Kyushu University Medical School say a novel combination of a specific sugar molecule with a pair of cell-killing drugs prompts a wide variety of cancer cell types to kill themselves, a process called apoptosis or programmed cell death.

The findings are reported online in the journal Cancer Research.

“The goal of targeted therapy is to stop the growth…
