Striatal injection of 6-hydroxydopamine induces retrograde degeneration and glial activation in the nigrostriatal pathway [PDF]

open access: yesActa Cirúrgica Brasileira, 2003
PURPOSE: The effect of a highly selective 6-hydroxydopamine (6-OHDA)-induced lesion of the nigrostriatal system on the astroglial and microglial activation was analysed in adult Wistar rats after an unilateral striatal injection of the neurotoxin ...

INDIRECT MEASURES OF NEUROPROTECTION ARE PARAMETERS TO AVOID: EXAMPLES FROM RESEARCH ON NEONATAL RAT HYPOXIA-ISCHEMIA

open access: yesImage Analysis and Stereology, 2011
The use of indirect measures of neuronal injury or neuroprotection, such as brain weight or the neuronal density of neurons, can lead to misinterpretations of biological processes.

Structural plasticity in the entorhinal and perirhinal cortices following hippocampal lesions in rhesus monkeys

open access: yesHippocampus, Volume 33, Issue 10, Page 1094-1112, October 2023., 2023
Abstract Immature neurons expressing the Bcl2 protein are present in various regions of the mammalian brain, including the amygdala and the entorhinal and perirhinal cortices. Their functional role is unknown but we have previously shown that neonatal and adult hippocampal lesions increase their differentiation in the monkey amygdala. Here, we assessed

STEREOLOGICAL ESTIMATION OF ITO CELLS FROM RAT LIVER USING THE OPTICAL FRACTIONATOR - A PRELIMINARY REPORT

open access: yesImage Analysis and Stereology, 2011
In the last two decades, much light has been shed on hepatic fibrosis, and the activation / proliferation of Ito cells (IC) emerged to play a central role.

Loss of neurons from laminas I-III of the spinal dorsal horn is not required for development of tactile allodynia in the spared nerve injury model of neuropathic pain [PDF]

open access: yes, 2005
It has been proposed that death of inhibitory interneurons in the dorsal horn contributes to the neuropathic pain that follows partial nerve injury. In this study, we have used two approaches to test whether there is neuronal death in the dorsal horn in ...

THE APPLICATION OF STEREOLOGICAL METHODS FOR THE QUANTITATIVE ANALYSIS OF THE ATHEROSCLEROTIC LESIONS IN RABBITS

open access: yesImage Analysis and Stereology, 2011
Atherosclerosis is a chronic metabolic and inflammatory disease of vascular arteries. Insome cases, it comes the accumulation of the inflammatory cells and extracellular matrix in vessel intima, which lead to the narrowing of the vessel lumen. The aim of

Stereological estimation of ovarian oocyte volume, surface area and number: application on mice treated with nandrolone decanoate

open access: yesFolia Histochemica et Cytobiologica, 2012
Changes in the number and size of oocytes can lead to fertilization problems. The present study aimed to evaluate the number, volume, and surface area of oocytes in healthy as well as nandrolone decanoate-treated (ND) mice using stereological methods ...

The optical fractionator sampling scheme.

open access: yes, 2013
A hemisphere was randomly selected and sectioned into 100 µm-thick coronal sections, from which a predetermined fraction, the section sampling fraction (ssf), was systematically (sampled sections were separated by an equal distance) and randomly (the ...
