Dentate granule cells (DGCs) are the principal cell population of the hippocampal dentate gyrus, and granule cells provide the main excitation to the hippocampus proper via their mossy fibers axons. Although it is well established that granule cells express various growth factors and growth factor receptors, the functional effects of growth factors on the(More)
A transgenic mouse containing 70 copies (ND4) of the transgene encoding DM20, a myelin proteolipid protein, appeared clinically normal up to 3 months of age. By 8-10 months, it showed tremors, unsteady gait, and died shortly thereafter. We concluded that the clinical symptoms correlated with demyelination based on the following criteria: 1) at 10 months of(More)
The molecular mechanisms that underlie dentate granule cell axon (i.e., mossy fiber) growth during development and following seizure-induced hippocampal injury remain unknown. Part of this process may involve specific factors that support dentate granule cells during differentiation, and molecular cues that allow the appropriate growth of mossy fiber axons(More)
Many studies have demonstrated that constraint induced movement therapy (CIMT) improves upper limb motor impairment following stroke. This rehabilitation method combines constraint of the less-affected upperlimb with intensive training of the paretic limb. The aim of the present study was to evaluate, in a single case study, the respective effects of each(More)
INTRODUCTION Patients suffering Dopa-Responsive Dystonia present dystonia, abnormal postural balance and gait impairment. Treatment with levodopa typically improves these three symptoms. The present study provides an extensive analysis of gait and posture in a patient with Dopa-Responsive Dystonia, prior to and during levodopa therapy. METHOD The patient(More)
Using vanadyl sulphate, sodium orthovanadate or bis(maltolato)oxovanadium (BMOV), Cruz TF, Morgan A, Min W (1995, Mol Cell Biochem 153: 161-166) have recently demonstrated the antineoplastic effects of vanadium in mice. In this study, the antineoplastic effects of BMOV against human tumour cell lines was confirmed, and this effect was shown to depend on the(More)
Knee recurvatum (KR) during gait is common in hemiplegic patients. Quadriceps spasticity has been postulated as a cause of KR in this population. The aim of this study was to assess the role of rectus femoris spasticity in KR by using selective motor nerve blocks of the rectus femoris nerve in hemiparetic stroke patients. The data from six adult,(More)
Selected postoperative complications following a craniotomy are discussed in relation to assessment and nursing care. Clinical differentiation between structural and metabolic postoperative complications is emphasized. The signs, symptoms, diagnostic aids and nursing implications related to each of these two major classifications of complications are(More)
