[Social and geographical determinants of cancer care management in France - colorectal cancer incidence in Calvados from 1997 to 2004].

Background: Numerous studies have underlined an important deprivation gap in survival in all industrialized countries, prognosis being constantly poorer for the most deprived patients. Beside clinical factors, the explanation of this gap in survival could be partly explained by the influence of socio-geographical environment on cancer care management. The aim of this retrospective population-based study was to investigate the influence of socio-geographical determinants on access to a reference care centre.

Electrochemical response of a carbon paste electrode containing an adsorbed species on incorporated alumina.

The electrochemical response of carbon paste electrode was investigated containing an inorganic and a non-electroactive compound on which an electro- active organic molecule was adsorbed. Alizarin S was chosen as the test molecule adsorbed on 150 m(2)/g of alumina, because this molecule is either easily reduced or oxidized on carbon. The electrode response was found to be linear for low amounts of alumina containing a known amount of Alizarin S.
