A major impediment to CNS repair is the glial scar, which forms following damage and is composed mainly of ramified, 'reactive' astrocytes that inhibit neuronal regrowth. The transition of astrocytes into this reactive phenotype (reactive gliosis) is a potential therapeutic target, but glial scar formation has proved difficult to study in monolayer cultures because they induce constitutive astr...
We report the radiologic and pathologic findings of an intracerebral schwannoma. MR imaging studies showed a superficially located cystic mass with an enhancing nodule and evidence of peritumoral edema or gliosis.
The PDAPP transgenic mouse overexpresses human amyloid precursor protein V717F (PDAPP minigene) and develops age-related cerebral amyloid-beta protein (Abeta) deposits similar to senile plaques in Alzheimer's disease. We find age-related cortical and limbic Abeta deposition that begins at 8 months and progresses to cover 20-50% of the neuropil in cingulate cortex, entorhinal cortex, and hippoca...
Basic fibroblast growth factor (bFGF) was injected with dissociated substantia nigral cells into the striatum of rats prepared by unilateral lesion of the nigrostriatal pathway with 6-hydroxydopamine. The transplanted cells with 5 and 50 ng bFGF reduced the apomorphine-induced rotations by 40 and 30%, respectively, while the decrement of rotations was only 15% in the grafted control without bFG...
Stroke is the second leading cause of death. Experimental animal models of cerebral ischemia are widely used for researching mechanisms of ischemic damage and developing new drugs for the prevention and treatment of stroke. The present study aimed to comparatively investigate neuroprotective effects of aspirin (ASA), decursinol (DA) and new synthetic aspirin-decursinol adduct (ASA-DA) against t...
Blindness attributed to vitamin A deficiency afflicted 47 out of 197, and 15 out of 29 new-born dairy calves on 2 farms. Other clinical signs included doming of the forehead, thickening of the carpal joints, incoordination and weakness. Gross lesions in 8 of the calves examined consisted in hydrocephalus and thickened occipital and sphenoid bones. In 4 of these calves the optic nerves were cons...
Magnetic resonance spectroscopy allows in vivo neurochemical exploration of multiple sclerosis (MS) lesions and normal appearing white matter on MRI. It gives insights into pathophysiology: inflammation (increase of choline), recent demyelination (increase in lipids and choline), axonal dysfunction (decrease of NAA), gliosis (increase of myoinositol). The spectroscopic profile of lesions is not...
