A new techniques is presented in order to reconstruct 3D object surface from several closed, in general, non-planar curves, including contours that were outlined manually. A 2D distance map is used to reconstruct object of a different shapes. The branching problem is also discussed.
Among the large cells located in the posterior of Echinostoma caproni and E. paraensei miracidia are secretory cells, germinal cells (GC), and undifferentiated cells. Secretory cells do not give rise to progeny, whereas GC do. Undifferentiated cells develop into GC that can also divide to produce embryos. Cleavage of GC of E. caproni occurs only after the(More)
The somatic musculature in trematode hermaphroditic generation (cercariae, metacercariae and adult) is presumed to comprise uniform layers of circular, longitudinal and diagonal muscle fibers of the body wall, and internal dorsoventral muscle fibers. Meanwhile, specific data are few, and there has been no analysis taking the trunk axial differentiation and(More)
Experimental infections of the mollusc Biomphalaria pfeifferi by Echinostoma caproni miracidia (Mi) were carried out in order to analyze the migration and development of mother sporocysts (MS) at 26 C. Miracidia penetrated different parts of the host's body, such as the mantle collar, the foot and head covering (including velum and tentacles), the mantle(More)
