Comparing the teaching interaction procedure to social stories for people with autism.

This study compared social stories and the teaching interaction procedure to teach social skills to 6 children and adolescents with an autism spectrum disorder. Researchers taught 18 social skills with social stories and 18 social skills with the teaching interaction procedure within a parallel treatment design. The teaching interaction procedure resulted in mastery of all 18 skills across the 6 participants.

Nitric oxide synthase activity in genetic hypertension.

A porphyrinic sensor was used to monitor nitric oxide released from cultured endothelial and vascular smooth muscle cells obtained from genetically hypertensive rats and from a normotensive reference strain of rats. Endothelial cell nitric oxide synthase (the constitutive enzyme) was stimulated with bradykinin, and vascular smooth muscle cell nitric oxide synthase (the inducible enzyme) was induced with interleukin-1 beta. Both types of cells from hypertensive rats released less nitric oxide than did cells from normotensive rats.
