Researchers pioneer new gene therapy technique using natural repair process

...herapy attempts for SCID have been only moderately successful because of technical difficulties in the delivery method. In one instance, the correct IL-2R gene was delivered to mutant cells of SCID children by a disabled virus, but some subsequently developed leukemia because the virus inadvertently turned on a...

Sponges as drugs

...ar 9 of the 151 species of sponge observed but was successful with only 3 species. Although the survival rates of these species were generally very high, the growth rates were very slow and unpredictable. Moreover, the reared sponges produced less of the biologically-active substances than their natural counter...

Census of Marine Life explorers surprised by diversity, density of Arctic creatures

Stem cell treatment improves mobility after spinal cord injury

...nic stem cell-derived treatment they developed was successful in restoring the insulation tissue for neurons in rats treated seven days after the initial injury, which led to a recovery of motor skills. But the same treatment did not work on rats that had been injured for 10 months. The findings point to the po...
