UNLABELLED Urethane is widely used as an anesthetic for animal studies because of its minimal effects on cardiovascular and respiratory systems and maintenance of spinal reflexes. Despite its usefulness in animal research, there are no reports concerning its molecular actions. We designed this study to determine whether urethane affects(More)
The effects of neurotrophic factors on translational activation were investigated in cortical neurons. Brain-derived neurotrophic factor (BDNF) increased protein synthesis within 30 min, whereas insulin produced a weaker enhancement of protein synthesis. BDNF-triggered protein synthesis was inhibited by LY294002, PD98059, and rapamycin, whereas the effect(More)
The evolution of EEG, visual and auditory evoked responses (VER and AER) and sleep is described in three cases of semilobar holoprosencephaly. During the neonatal period, the waking EEG was characterized by almost continuous high amplitude rhythmic alpha-theta activity in case 1 and 2, which became discontinuous during quiet sleep. Moderate amplitude(More)
The classification of the background EEG was performed in 132 fullterm neonates who had suffered perinatal hypoxia by visual inspection of whole polygraphic records of 2--3 h duration, i.e., maximally depressed, markedly depressed, moderately depressed, mildly depressed, minimally depressed, normal and other, according to the distribution of 7 EEG patterns.(More)
BACKGROUND Some of the effects of ethanol in the central nervous system are due to changes in function of ligand-gated ion channels. Production of detectable amounts of acetaldehyde, a primary metabolite of ethanol, has been demonstrated in brain homogenates. The aim of this study was to determine whether central actions that are often attributed to ethanol(More)
The electroencephalographic features and their evolutional changes with age were described in three cases of lissencephaly syndrome diagnosed by CT scan. The case with more severe lissencephaly displayed very similar EEG findings. In early or middle infancy when infantile spasms began, EEG showed very high amplitude (more than 400 microV) slow waves mixed(More)
We recently demonstrated that blood-brain barrier permeabilization using mannitol enhances the therapeutic efficacy of systemically administered human umbilical cord blood (HUCB) by facilitating the entry of neurotrophic factors from the periphery into the adult stroke brain. Here, we examined whether the same blood-brain barrier manipulation approach(More)
Five children who had apneic attacks as a manifestation of epileptic seizures are reported. In three children, the apneic attacks were the sole symptom of epileptic fits. The other two children had additional types of seizures. The apneic seizures usually lasted one to two minutes and were characterized by respiratory embarrassment rather than complete(More)
Electroclinical features of convulsive apnea and its relation to the behavioral state were described on the basis of polygraphic recordings from 21 newborns with various underlying disorders, including perinatal anoxia, purulent meningitis, and intracranial bleeding. The most frequent ictal discharges were rhythmic alpha waves, but other types of(More)
