This development can be considered as new in so far as it reverses the long-

The topic "Gene Expression and Its Regulation" was received enthusiastically, and, thanks to the vision of our Argentine colleagues, the program developed rapidly under the leadership of Dr. Gabriel Favelukes as General Secretary of the Symposium.

the ineluctable sequence of degenerative changes in muscle associated with that disease have thus far been frustrated. Nevertheless, because the characteristic weakness appears only late in infancy, and for other reasons as well, a defect in the genetic regulation of muscle cell development seems li
