Visually Induced Kinaesthetic Illusion Combined with Therapeutic Exercise for Patients with Chronic Stroke: A Pilot Study.

Objective: Kinaesthetic perceptional illusion by visual stimulation (KINVIS) combined with neuromuscular electrical stimulation (NMES) and conventional therapeutic exercise (TherEX) has been shown previously to enhance motor function in stroke patients with chronic hemiparesis. The aim of this preliminary study is to assess the effects of a repetitive KINVIS intervention combined with TherEX, but without NMES, on upper limb motor function of patients with stroke-induced hemiparesis.

Design: A quasi-experimental study, with pretest-posttest for 1 group Patients: Ten patients with stroke-induced, chronic, severe upper limb hemiparesis.

Adult classical glioblastoma with a BRAF V600E mutation.

The B-Raf proto-oncogene serine/threonine kinase (B-Raf) is a member of the Raf kinase family. The BRAF V600E mutation occurs frequently in certain brain tumors such as pleomorphic xanthoastrocytoma, ganglioglioma, and pilocytic astrocytoma, and less frequently in epithelioid and giant cell glioblastoma. BRAF V600E mutation in these cases has been canonically detected using Sanger sequencing or immunohistochemistry but not with next-generation sequencing (NGS).

Correlation between positron emission tomography findings and glucose transporter 1, 3 and L-type amino acid transporter 1 mRNA expression in primary central nervous system lymphomas.

Primary central nervous system lymphoma (PCNSL) is an aggressive form of non-Hodgkin lymphoma with a poor prognosis. [F] 2-fluoro-2-deoxy-D-glucose (FDG) and L-(methyl-C)-methionine (MET) are the most widely used tracers in oncological positron emission tomography studies for PCNSL and commonly identify hypermetabolic lesions through increased uptake of FDG and MET. However, the mechanisms underlying the uptake of FDG and MET in PCNSL have not been clearly determined.

Disturbed resting functional inter-hemispherical connectivity of the ventral attentional network in alpha band is associated with unilateral spatial neglect.

Unilateral spatial neglect (USN) is one of the most common symptoms of right hemisphere damage; its classical symptom is that patients fail to respond to information on their left side. It has been postulated that disturbance of 2 separate attentional networks relates to the occurrence of USN. However, little is known about the underlying mechanism and neuronal substrates.

Reversible splenial lesion in postpartum cerebral angiopathy: a case report.

Reversible lesions on magnetic resonance imaging that transiently restrict diffusion in the splenium of the corpus callosum (SCC) without any other accompanying lesions have been reported in various clinical conditions. We offer the first report of postpartum cerebral angiopathy with reversible SCC lesions.

Quantitative imaging of spontaneous neuromagnetic activity for assessing cerebral ischemia using sLORETA-qm.

To image cerebral neural activity in ischemic areas, we proposed a novel technique to analyze spontaneous neuromagnetic fields based on standardized low-resolution brain electromagnetic tomography modified for a quantifiable method (sLORETA-qm). Using a 160-channel whole-head-type magnetoencephalographic system, cerebral magnetic fields were obtained pre- and postoperatively from 5 patients with unilateral internal carotid artery occlusive disease and 16 age-matched healthy volunteers. For quantitative imaging, voxel-based time-averaged intensities of slow waves in 4 frequency bands (0.

Recovery of spontaneous neuromagnetic activity after extracranial-intracranial bypass in a patient with middle cerebral artery occlusion.

Patient And Methods: Cerebral blood flow and neuromagnetic activity were measured using (123)I-iodoamphetamine-single photon emission computed tomography (IMP-SPECT) and magnetoencephalography (MEG), before and after extracranial-intracranial (EC-IC) bypass surgery in a 55-year-old woman with unilateral middle cerebral artery occlusion that occurred with intraventricular haemorrhage. Frequency analysis of slow waves measured on MEG was performed using an adaptive beam-former method.

Results And Discussion: Distribution of delta waves was observed pre-operatively corresponding to areas of cerebral hypo-perfusion as confirmed by IMP-SPECT but disappeared post-operatively with improvements in cerebral blood flow.

Prediction of seizure outcome following epilepsy surgery: asymmetry of thalamic glucose metabolism and cerebral neural activity in temporal lobe epilepsy.

Objective: The objective of this retrospective study is to analyze whether preoperative functional imaging studies using FDG-PET and MEG enable prediction of postoperative seizure outcomes.

Methods: Thirty-six patients with intractable temporal lobe epilepsy were studied. Asymmetry index of tCMRgluc (PET-AI) and the equivalent current dipole intensity of first response of SEF (SEF-AI) were determined preoperatively using (18)F-fluorodeoxyglucose-positron emission tomography (FDG-PET) and magnetoencephalography (MEG), respectively.

Histone deacetylase inhibitor, FK228, induces apoptosis and suppresses cell proliferation of human glioblastoma cells in vitro and in vivo.

We investigated the effects of FK228 on cell proliferation and apoptosis against human glioblastoma (GM) T98G, U251MG, and U87MG cells. Upon exposure to FK228, cell proliferation was inhibited, and apoptosis detected by the cleavage of CPP32 was induced. FK228 increased the expression levels of p21 (WAF-1) and of pro-apoptotic Bad protein in all GM cells.

Histone deacetylase inhibitors such as sodium butyrate and trichostatin A inhibit vascular endothelial growth factor (VEGF) secretion from human glioblastoma cells.

We investigated the effects of histone deacetylase (HDAC) inhibitors such as sodium butyrate (SB) and trichostatin A (TSA) on the expression of vascular endothelial growth factor (VEGF) by human glioblastoma T98G, U251MG, and U87MG cells. The glioblastoma cells secreted three VEGF isoforms, VEGF (189), (165), and (121), although the expression levels of VEGF differed between the cell types. Treatment with either 5mM SB or 100 ng/ml TSA reduced VEGF secretion in conditioned media and reduced VEGF mRNA expression.
