INTRODUCTION It is well established that childhood maltreatment has a detrimental impact on the brain, particularly the hippocampus. However, the hippocampus is a functionally and structurally heterogeneous region, and little is known about how maltreatment might affect hippocampal subregion development throughout important periods of plasticity. This study investigated whether childhood maltre...
Proechimys (Rodentia: Echimyidae) is a neotropical rodent of the Amazon region that has been successfully colonized in the laboratory and used for experimental medicine. Preliminary studies indicated that Proechimys (casiragua) rodents express an atypical resistance to developing a chronic epileptic condition in common models of temporal lobe epilepsy. Moreover, previous investigation of our la...
BACKGROUND Greater hippocampal volume is observed in healthy older adults after short-term structured exercise. Whether long-term exposure to real-world physical activity (PA) programs has similar effects for sedentary older adults with impaired mobility and comorbid conditions is not known. HYPOTHESIS A long-term moderate intensity regimen of PA is related to larger volume of the hippocampus...
Corpora amylacea (CA) are globular bodies usually 10 – 50 μm in diameter mainly made up of glucose polymers (polyglucosans), which stain strongly with periodic acid-Schiff (PAS) staining. They are commonly seen in different subependymal and subpial regions, fornix, olfactory tract, posterior column of the spinal cord, and velum medullare anterius [1]. Large amounts of CA have been reported in a...
Increased melatonin 1a-receptor immunoreactivity in the hippocampus of Alzheimer's disease patients.
The pineal secretory product melatonin has, in addition to regulating retinal, circadian and vascular functions, neuroprotective effects. Blood melatonin levels are often decreased in Alzheimer's disease (AD), a progressively disabling neurodegenerative disorder. In this study we provide the first immunohistochemical evidence for the localization of melatonin 1a-receptor (MT(1)) in aged human h...
