Fragile X syndrome [fra (X)] is currently accepted as the second most frequent chromosomal disorder associated with developmental disability. Although next to Down syndrome in frequency, no postmortem studies of confirmed adult cases had been reported. The autopsy examination of a 62-year-old, moderately retarded man with the fra (X) syndrome confirmed the(More)
Our material presents two patterns of white matter lesions in the brain of newborns dying with the clinical diagnosis of intrauterine or perinatal pathology: (1) classical periventricular ischemic infarction resulting in coagulative necrosis and (2) diffuse periventricular colliquative necrosis, in some cases involving the center of the cerebral(More)
RAGE (receptor for advanced glycation end-products) participates in the influx transport of glycated Aβ (amyloid beta) from the blood to the brain. Because little is known of the RAGE operating in brain barriers such as those in the choroid plexus and ependyma, the aim of the present study was to examine the immunodistributions of RAGE and Aβ peptides in(More)
In this study a comparison of the myelination rate in humans in normal and pathologic conditions was made. The progress of myelination was examined on slides stained by the Klüver-Barrera method and evaluated as to four degrees. The prenatal myelination in the brain stem in a group of newborns who died of pregnancy pathology was correlated with normal brain(More)
The pineal gland is an organ involved in regulation of homeostasis and body rhythms. It plays an important role in the growth foetuses and adaptation of newborns to new environmental conditions. The requirements of foetuses and newborns progressively change during development. The purpose of the study was to evaluate morphological changes of pineal glands(More)
There are relatively few studies on microglia of human developing brain thus function and location of these cells at this period of life are unknown. Moreover, all of them concentrated on the cells in very early period of fetal life. To achieve further insight into the participation of microglial cells in the development of the central nervous system the(More)
The aim of our neuropathologic study was to evaluate the changes in the CNS of children occurring in course of neoplastic diseases. First of all we looked for those which correspond to paraneoplastic syndromes and others which could be considered as secondary toxic lesions after prolonged chemotherapy. Twenty seven brains of children aged 0-11 years, 20(More)
The blood-brain barrier prevents infiltration of peripheral immunocompetent cells into the CNS under physiological conditions. Following brain trauma there is reported a rapid and massive immunological response. Our earlier data indicated that surgical brain injury causes breaking of brain parenchyma integrity and results in cell changes and death,(More)
