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.

The application of stereology in hepatobiliary conditions is essential liver volume estimation. Computerized topographic scan with contrast a reliable method scanning for precise boundaries demarcation. Liver volumetry varies relation to different factors. Reports showed correlation sex and body mass index. Steady between age ethnicity not established. This study aimed design protocol measureme...

background and aims: this study examined sub-chronic effects of methamphetamine (meth) on the stereological parameters in the cornu ammonis (ca) of the hippocampus in adult mice. materials and methods: fifteen adult male mice, eight weeks old, were randomly divided into three groups: receive saline (controls), or low-dose (ld) 2.5 mg/kg meth, or high-dose (hd) 25 mg/kg meth, via daily intraperi...

Systematic sampling is widely used in stereology. Practical stereology is commonly based on measurements on serial sections and grids of quadrats, cycloids or points superimposed on sections. The precision of estimators based on systematic measurements can be assessed, using the so-called transitive methods due to [9]. The use of the transitive methods in stereology has been discussed in a seri...

The present article reviews the relevant stereological estimators for obtaining reliable quantitative structural data from the lungs. Stereological sampling achieves reliable, quantitative information either about the whole lung or complete lobes, whilst minimising the workload. Studies have used systematic random sampling, which has fixed and constant sampling probabilities on all blocks, sect...

objective(s):the hippocampus has been implicated in pathophysiology of schizophrenia. prenatal stress is a contributing risk factor for a wide variety of neuropsychiatric diseases including schizophrenia. this study examined long-term effects of prenatal restraint stress on the stereological parameters in the cornu ammonis (ca) of adult male rats as an animal model of schizophrenia. materials a...

objective(s) in recent years concerns have been raised regarding the incidence of male reproductive disorders from exposure to endocrine disruptors. so, chronic effects of di(2-ethylhexyl)phthalate were studied on histological and stereological structure of testis in adult wistar rats. materials and methods thirty two adult wistar rats were randomly divided in four equal experiment groups; oil ...
