Self-assembled nano-sized probes allow Penn researchers to see tumors through flesh and skin

...ble than MRI-based methods and free of the harmful side effects associated with radioactivity. In this imaging system, the flourophores can also be tuned to respond to different wavelengths of near-infrared light. This sets the stage for using emissive polymersomes to target multiple cancer cell-surface m...

Rats infected as newborns grew up vulnerable to memory problems during an immune challenge

...stem works on its own, without the complication of side effects. The team found that E. coli-infected pups later injected with LPS had significantly lower concentrations of cytokines called interleukins than control pups (they tested 32 PUPS in all). Immune cells release these cytokines, or certain prote...

Discovery Promises Simpler Therapy for Sickle Cell Disease

It points the way to using gene therapy to cure and/or treat a host of other disease that occur because of the lack of genes in this ar...

Researchers identify protein crucial for survival of Lyme-disease bacterium

...nds to get ignored, Dr. Norgard said, is the other side of the coin. "This organism has to live half of its life cycle in a tick," he said. "There must be subsets of genes important to its survival there. If it can't exist in ticks, it can't maintain itself in nature and hence can't infect animals or hum...

Nanoparticles offer new hope for detection and treatment
