Genetically modified natural killer immune cells attack, kill leukemia cells
...eukemia. "We look forward to seeing this strategy being added to the management of children with ALL," said Chihaya Imai, M.D., the postdoctoral student who did most of the work on this project. ...Probing The Promise And Perils Of Nanoparticles
...nanoparticles called polycationic polymers—already being used to deliver drugs and genes—to see if they behaved like dendrimers. "It turns out that they cause the same permeability and, in general, they cause membrane destruction as well," said Banaszak Holl. Neutral polymers, however, did not damage membr...Introduced foxes transformed vegetation on Aleutian Islands from lush grasslands to tundra
...nd animal samples. "The terrestrial ecosystem was being subsidized by marine-derived nutrients, and the foxes basically cut off the subsidies by interrupting the flow of nutrients coming from offshore," Croll said. "It transformed the plant community from one that does well in nutrient-rich conditions to ...Gene Therapy For Parkinson's Disease Moves Forward In Animals

...athing pattern. The chamber, which housed the moth being studied, was filled first with air that had been freed of carbon dioxide. Next, a device measured when and how much carbon dioxide originated from the insect. Bradley explained that insects typically maintain 4-5 kilopascals of oxygen in their respi...NYC's First Rapid HIV Drug-resistant AIDS Case Prompts Call to Step Up HIV Prevention
