The accumulation of calcium ions (Ca) was examined in the rat brain by means of 45Ca autoradiography following the application of a weak anodal direct current to the surface of the sensorimotor cortex. Repetition of the anodal polarization with 3.0 microA for 30 min caused more Ca to accumulate in the cerebral cortex. The degree and extent of accumulation(More)
An anodal direct current of 0.3 microA or 30.0 microA was unilaterally applied for 30 min or 3 hr to the surface of the sensorimotor cortex of rats, and the effects of anodal polarization on protein kinase C (PKCgamma) activity were examined. The brains were processed by means of immunocytochemistry using the monoclonal antibody 36G9 raised against purified(More)
c-Fos protein-like immunoreactivity (IR) was investigated in the rat brain following an application of weak anodal direct current to the surface of the unilateral sensorimotor cortex in an attempt to elucidate the cellular and molecular bases of central plasticity. Anodal polarization resulted in a massive increase in c-Fos protein-like IR in neurons of the(More)
Protein kinase C gamma (PKC gamma)-like immunoreactivity was examined in the rat brain, employing the monoclonal antibody 36G9 raised against purified PKC gamma, after an application of weak anodal direct current to the surface of the sensorimotor cortex. Anodal polarization with 3.0 microA for 30 min resulted in a pronounced increase in the number of PKC(More)
The expression of protein kinase c gamma (PKC gamma) and c-fos protein was examined by means of double labeling in the rat brain in relation to the molecular mechanism of central plastic changes associated with anodal polarization. Under normal, non-polarized condition, approximately 75% of all fos positive neurons in the neocortex were immunopositive for(More)
An anodal direct current of 3.0 microA or 30.0 microA was unilaterally applied for 30 min or 3 h to the surface of the sensorimotor cortex of rats, and the effects of polarization on the morphology of brain cells were examined by light microscopy. After five repeated anodal polarization trials, dark neurons appeared mainly in the polarized neocortex(More)
To clarify the pathogenesis and molecular basis of ischemia-related nerve cell death, we examined the occurrence of DNA fragmentation as a hallmark of apoptotic cell death following incomplete ischemia in the rat brain by means of in situ end labeling of fragmented DNA. Incomplete ischemia was produced by permanently occluding one carotid artery, while(More)
Expression of c-fos immunoreactivity was investigated in rat brain after unilateral application of a weak anodal direct current (anodal polarization) to the sensorimotor cortex of rats. Increases in Fosimmunopositive neurons were observed transiently in the neocortex, cingulate cortex, piriform cortex, and hippocampal formation, which were ipsilateral to(More)
Using EUROMOD, we cross-validate two types of micro-data presently available in the Grand-Duchy of Luxembourg, administrative data on one hand and survey data on the other hand. While administrative data, extracted from the recently implemented Social Security Data Warehouse, contain information of the whole population of Luxembourg (449,000 observations)(More)
The expression of c-fos protein was examined by means of immunocytochemistry in the rat brain following incomplete ischaemia, to elucidate the molecular mechanisms of post-ischaemic neuronal death and of the modulated neurotransmission of surviving neurons. Incomplete ischaemia was produced by permanent unilateral or bilateral common carotid artery (CCA)(More)
