[Library search of UV spectra of organic environmental pollutants by artificial neural network].

In this paper, the artificial neural network (ANN) was applied to the library search of UV spectra of organic environmental pollutants. The optimization of network parameters was discussed and the effects of noise and impurity were investigated in detail. The use of derivative spectra for ANN library search was proposed to enhance the resolution of the UV spectra. This method could speed up the convergence of the network and could enhance the tolerance of impurity level, but was subject to noise comparing with the ANN using conventional UV spectra. Results show that the ANN is superior to the correlation coefficient method in resistance to noise and impurity.

A hybrid artificial vascular graft based upon an organ reconstruction model. Significance and design criteria of an artificial basement membrane.

The design of an artificial basement membrane is one of the central concerns in a hybrid artificial vascular graft. The design criteria defined here include 1) structural matrix, 2) enhanced adhesion and growth of endothelial cells, and 3) ensured antithrombogenicity. The designed artificial basement membrane is a complex gel of type I collagen with dermatan sulfate that drastically alters the cellular responses for both endothelial cells and platelets. The incorporation of a very small amount of dermatan sulfate was sufficient to enhance adhesion and growth of endothelial cells and to suppress platelet adhesion and activation.
