1. FPL 67156 (6-N,N-diethyl-beta, gamma-dibromomethylene-D-ATP), is a newly synthesized analogue of ATP. 2. In a rabbit isolated tracheal epithelium preparation, measuring P2U-purinoceptor-dependent chloride secretion, FPL 67156 was discovered to potentiate the responses to UTP but not those to ATP-gamma-S. UTP agonist-concentration effect (E/[A]) curves(More)
In the current practice of finite element analysis of concrete structures, as well as rocks, cracks are considered to be densely distributed (smeared) throughout the finite area of the element (4,17.22,24). The assumption of continuous crack distribution seems reasonable in view of material inhomogeneity and the stabilizing effect of reinforcement, although(More)
