Study sheds new light on Lyme disease transmission
...lled vlsE, they found a large number of variations generated during tick feeding, compared to only one or two when the tick was not feeding. "We are excited by the findings because this once again supports the concept that arthropod vectors are not just flying or crawling syringes that go around inoculating b...Gene therapy for muscular dystrophy

Skeletal muscle (which is affected by MD) is very bad at presenting weve never seen an immune response, as long as the expressed protein is restricted to the skeletal muscle.

In 1996, the Condon-Payne team was awarded state grants from the Maryland Industrial Partnership (MIPS) program to develop a crab chum-to-chitosan process and to perform a preliminary economic analysis.

It would shed light, for example, on where people might have obtained certain genes and what role they played in their source animal ancestors.

Introducing a fluorescent calcium marker into the cells, which were kept alive in culture dishes, the scientists were able to record with a camera attached to a microscope the rapid calcium burs...Researchers find new clues to nerve cell development
