We study the information included in sandfly wings in order to test this organ as a source for the specific discrimination. The cartesian coordinates of the vein intersections are collected using a microscope and a graphic table. From these data a specifically developed software searches for discriminant characters. The present study on 32 New World species(More)
INTRODUCTION The cerebral venous system is poorly known and is best appreciated based on macroscopic anatomical considerations. We present an anatomical and immunohistochemical study to better define the morphological characteristics of the junction between the inferior cortical veins and the transversal sinuses.

The diagnosis of hereditary retinal syndromes may be difficult for a physician because of their number and variability. A computer assisted diagnosis of these syndromes can be useful in such cases. We used an identification software (XPER) for this purpose. The data base contains more than 67,000 elementary data that enable us to define 115 hereditary(More)
