We have developed a personal procedure for the radioimmunoassay of gastrin (lower detection limit 3 pg/ml). Using 5-fold concentrated lyophilized salivary samples, we are able to detect the basal content of gastrin immunoreactivity in saliva of normal fasting people (mean +/- SD: 1.38 +/- 0.61 pg/ml) compared to plasma gastrin (mean +/- SD: 28.88 +/- 11.00(More)
In this paper we prove some existence and regularity results for weak solutions to a class of nonlinear parabolic equations whose prototype is  ∂u ∂t −∆pu = f(x, t) in Q, u(x, 0) = 0 in Ω, u(x, t) = 0 on Γ, where Ω is a bounded open subset of IR , N ≥ 2, Q is the cylinder Ω×]0, T [, T > 0, Γ the lateral surface ∂Ω×]0, T [, 4p is the so called p−Laplace(More)
we extend the results. of [I-5] on the uniqueness of solutions of parabolic equations. Our results give also some regularity results which complete the existence results made in [6-81. @ 2001 Elsevier Science Ltd. All rights reserved.

Nonlinear elliptic Neumann problems, possibly in irregular domains and with data affected by low integrability properties, are taken into account. Existence, uniqueness and continuous dependence on the data of generalized solutions are established under a suitable balance between the integrability of the datum and the (ir)regularity of the domain.

− div ( |∇up|p−2∇up ) = f in Ω up = 0 on ∂Ω, where p > 1 and Ω is a bounded open set of R (N ≥ 2) with Lipschitz boundary. We analyze the case where Ω is a ball and the datum f is a non-negative radially decreasing function belonging to the Lorentz space LN,∞(Ω) and the case where the datum f belongs to the dual space W−1,∞(Ω). We are interested in finding(More)
