    In recent years, borderline epithelial tumors of the ovary have been investigated by morphometric techniques to allow for a differential diagnosis from benign and malignant neoplasms. In order to enhance this discriminant power, we have applied a new analytical procedure to the evaluation of the nuclear shape in epithelial ovarian tumors. Sixty nuclei of benign ovarian serous neoplasms, 60 nuclei of serous borderline tumors and 60 nuclei of serous carcinomas (18 cases in all) were examined using the software system SAM (Shape Analytical Morphometry). The morphometric procedure consisted of three different phases: (i) extraction of nuclear fundamental curve: this is a function curve giving the smoothing of the original contour by two parametric equations (separately for x and y values as dependent variables); (ii) evaluation of nuclear contour irregularities by Fourier analysis; (iii) evaluation of nuclear shape asymmetry by SAE (Shape Asymmetry Evaluator): this is the ratio between the length of a segment of a parabola interpolating the original curve points and a straight line joining its extremities for a 180° barycentric rotation according 10° steps. All the obtained independent parameters were submitted to statistical analysis. Nuclei of borderline tumors showed dimensional parameters which were intermediate between those of benign and malignant tumors. Both the asymmetry and the irregularities of nuclear contour were greatest in carcinomas.

    Abstract The circumstances of the discovery and the first morphological observations concerning an, archaic human skeleton found in Altamura (Bari), in the “Lamalunga” district are reported. The observations were made by anthropologists from Bari University, at the site of the discovery, in a cave (Le Solange cave), a few days after they were first spotted by speleologists from the Speleological Research Center of Altamura (C.A.R.S.) and from the “Vespertilio” group of the Italian Alpine Club (C.A.I.) of Bari. The human remains were found in a corner of a small cavity in close association with columnar stalagmitic formations. All the bones are partly covered with, or embedded in, calcareous concretion while others are visible but lined with a calcareous shell of varying thickness. It is possible to recognize the skull (lying on its back); part of the face is apparent including the orbits and all the frontal region. On the ground, very close to the skull, there are many postcranial bones, but not all immediately recognizable because of the concretions. Immediately in front of and below the frontal are the tworadii; between these and a femoral shaft is the complete, but inverted, mandible. Bothfemora, thetibiae and thefibulae are present. Furthermore, the righthumerus, the distal epiphysis of an ulna and some costal elements are recognizable. The elements furthest from thecranium appear to be the innominate bones, partly covered with calcitic crust. Inside the pelvis are heavily, concreted pieces of bone among which are a costal element and a vertebral body. From the general robusticity of the bones and the rather high and narrow iliac fossa, the skeleton can be judged that of an adult male. Considering the presence on thecranium at the same time of both progressive and ancient features the Altamura specimen can be placed in the group of fossils of the European mid-Pleistocene characterized by the presence of archaic morphological traits and by a progressive increase in Neanderthal traits.
