there are extensive evidences that show axonal processes of the nervous system (peripheral and/or central) may be degenerated after nerve injuries. wallerian degeneration and chromatolysis are the most conspicuous phenomena that occur in response to injuries. in this research, the effects of post-operative time following sciatic nerve crush on the number of spinal motoneurons were investigated....
background: phthalate esters have been shown to cause reproductive toxicity in both developing and adult animals. objective: this study was designed to assess long-term effects of maternal exposure to di (2-ethylhexyl) phthalate (dehp) on reproductive ability of both neonatal and adult male offspring. materials and methods: 60 female rats randomly divided in four equal groups; vehicle control a...
Automated stereological methods are presented for approximating the 3D size distribution of unimodal or bimodal precipitate dispersions considering 2D and 1D measurements taken from polydisperse spherical non-penetrating particle dispersions. A method to quantify uncertainty approximation as a function number sampled particles is demonstrated experimental data. The derivation verification analy...
OBJECTIVES To investigate the use of whole brain voxel based morphometry (VBM) and stereological analysis to study brain morphology in patients with medically intractable temporal lobe epilepsy; and to determine the relation between side, duration, and age of onset of temporal lobe epilepsy, history of childhood febrile convulsions, and grey matter structure. METHODS Three dimensional magneti...
Dear Editor, We are thankful to our colleagues for their interest in our paper and comments that they have provided. We could not agree more with the part of the letter regarding the method of sampling. On the basis of our 16-year-long experience in research on rat placentas, we underline sampling as one of the most important concepts in stereology, especially in the light of biological variabi...
Workshops are an important part of the IFPA annual meeting. At the IFPA meeting 2008 diverse topics were discussed in 12 themed workshops. Topics covered included: immunology of placentation; galectins and trophoblast invasion; signaling in implantation and invasion; markers to identify trophoblast subpopulations; placental pathology; placental toxicology; stereology; placental transport of fat...
