An original strategy is presented, combining stereological sampling methods based on test grids and data reduction methods based on diffusion maps, in order to build a knowledge image database with no bias introduced by a subjective choice of exploration areas. The practical application of the exposed methodology concerns virtual slides of breast tumors.

The principle that formed the basis of the most popular "assumption based" stereological methods for counting cells that were available prior to the advent of the more recently developed "design based" methods will be described in general terms. The major weaknesses inherent in the older methods will be described, along with how they have been eliminated by the design based methods.

BACKGROUND In this study we examined the effects of two different repeated Extracorporeal Shock Waves (ESW) on the consolidation period of the distraction osteogenesis (DO) of the rabbit mandible using stereological, radiological and immunohistochemical methods. MATERIAL AND METHODS DO was performed unilaterally in the mandible of 18 New Zealand rabbits (six months old, weighing between 2.5-3...

Vasectomy reversal by vasovasostomy after long-term vasectomy in men results in lower sperm counts and pregnancy rates compared with controls, and severe damage to spermatogenesis has been observed in some animal models such as mice. The primary aim of this study was to evaluate, using sophisticated stereological methods, whether vasectomy of 6 and 12 months in a non-human primate would lead to...

The present study was carried out to investigate the effect of Aeromonas Hydrophila endotoxins on the lung structure and the possible protective effect of inositol hexaphosphate (phytic acid) as a safe natural product using stereological analysis as well as histopathological and ultrastructural studies. 24 albino rats were used. The rats were divided into 3 groups: first control group injected ...

With a stationary random process of convex particles, we associate a density with values in the space of symmetric tensors of rank two, as a means of describing and measuring the anisotropy and mean orientation of the particles. The main result is a stereological formula allowing us to estimate this tensor from measurements in planar sections. MSC 2000: 60D05, 52A22.
