The action of dopamine and other monoamine neurotransmitters at synapses is terminated predominantly by high-affinity reuptake into presynaptic terminals by specific sodium-dependent neurotransmitter transport proteins. A complementary DNA encoding a rat dopamine transporter has been isolated that exhibits high sequence similarity with the previously cloned(More)
We show that a bilinear estimate for biharmonic functions in a Lipschitz domain Ω is equivalent to the solvability of the Dirichlet problem for the biharmonic equation in Ω. As a result, we prove that for any given bounded Lipschitz domain Ω in R d and 1 < q < ∞, the solvability of the L q Dirichlet problem for ∆ 2 u = 0 in Ω with boundary data in WA 1,q(More)
This paper contains two results on the L p regularity problem on Lipschitz domains. For second order elliptic systems and 1 < p < ∞, we prove that the solvability of the L p regularity problem is equivalent to that of the L p ′ Dirichlet problem. For higher order elliptic equations and systems, we show that if p > 2, the solvability of the L p regularity(More)
Surgically constructed compound eyes have been widely used to examine the development of retinotectal projections in amphibians. Such studies have been limited, however, by the lack of an adequate cellular marker with which to assess the contributions of grafted and host tissues to the later larval and adult retina. We have followed the growth of graft- and(More)
