Estrogen And Aging Affect Synaptic Distribution Of Phosphorylated Lim Kinase (Plimk) In Ca1 Region Of Female Rat Hippocampus
(Pergamon-Elsevier Science Ltd, 2008)
17 beta-Estradiol (E) increases axospinous synapse density in the hippocampal CA1 region of young female rats, but not in aged rats. This may be linked to age-related alterations in signaling pathways activated by synaptic ...
Postpubertal Decrease in Hippocampal Dendritic Spines of Female Rats
(Academic Press Inc Elsevier Science, 2008)
Hippocampal dendritic spine and synapse numbers in female rats vary across the estrous cycle and following experimental manipulation of hormone levels in adulthood. Based on behavioral studies demonstrating that learning ...
Early Time-Locked Gamma Response And Gender Specificity
(Elsevier Science Bv, 2006)
The aim was to investigate whether gender is a causative factor in the gamma status according to which some individuals respond with time-locked, early gamma response, G+, while the others do not show this response, G-. ...
Early Gamma Response of Sleep is Sensory/Perceptual in Origin
(Elsevier Science Bv, 2006)
The goal of the study was to investigate the gamma response of the brain and its functional correlates in rapid eye movements (REM) sleep and the three stages of non-REM sleep. Data on overnight sleep were acquired from ...
Time-Frequency Component Analyser And Its Application To Brain Oscillatory Activity
(Elsevier Science Bv, 2005)
Currently, event-related potential (ERP) signals are analysed in the time domain (ERP technique) or in the frequency domain (Fourier analysis and variants). In techniques of time-domain and frequency-domain analysis ...
Generalised Periodic Epileptiform Discharges: Clinical Features, Neuroradiological Evaluation And Prognosis In 37 Adult Patients
(W B Saunders Co Ltd, 2003)
Generalised periodic epileptiform discharges (GPEDs) are very rare patterns and are classified as periodic short-interval diffuse discharges (PSIDDs), periodic long-interval diffuse discharges (PLIDDs) and suppression-burst ...
Epileptic Nystagmus In A Patient With Nonconvulsive Status Epilepticus
(W B Saunders Co Ltd, 2004)
Epileptic nystagmus (EN) is a rare form of rhythmic eye oscillations Occurring during seizure activity. Not only convulsive states, but also nonconvulsive status may represent with EN and this phenomenon may be the only ...
Familial Adult Onset Myoclonic Epilepsy Associated With Migraine
(W B Saunders Co Ltd, 2000)
We report a new type of migraine associated epileptic syndrome in a family. adult onset myoclonic epilepsy with benign course and migraine. Affected members of the family had myoclonic and rare generalised tonic-clonic ...
Predictive Factors for Postoperative Outcome in Temporal Lobe Epilepsy According to Two Different Classifications
(W B Saunders Co Ltd, 2008)
Purpose: The determination of prognostic factors is important for predicting outcome after epilepsy surgery. We investigated the factors related to surgical outcome within a homogeneous group of patients suffering from ...
Spectrum Of Brain Changes In Patients With Congenital Muscular Dystrophy And Fkrp Gene Mutations
(Amer Medical Assoc, 2006)
Objectives: To report the spectrum of brain magnetic resonance imaging findings in 13 patients with congenital muscular dystrophy and FKRP gene mutations and to explore possible geno type-phenotype correlations. Design: ...
The Role Of Patient Companions In Long-Term Video-Eeg Monitoring
(W B Saunders Co Ltd, 2000)
In developing countries it is difficult to have full-time dedicated nurses in Epilepsy Monitoring Units (EMU). Our one-bed EMU is within the Neurology Service and is adequately staffed during daytime working hours only. ...
The Tendency To Have Psychogenic Non-Epileptic Attacks Out Of Camera View During Long-Term Video-Eeg Monitoring
(W B Saunders Co Ltd, 2002)
The aim of this study was to compare out of camera view seizure occurrence rates between psychogenic non-epileptic and epileptic seizures during long-term video-EEG monitoring. From 1996 to 2001, 208 adult patients were ...
A Nanomedicine Transports A Peptide Caspase-3 Inhibitor Across The Blood-Brain Barrier And Provides Neuroprotection
(Soc Neuroscience, 2009)
Caspases play an important role as mediators of cell death in acute and chronic neurological disorders. Although peptide inhibitors of caspases provide neuroprotection, they have to be administered intracerebroventricularly ...
Assessment of Citrullinated Myelin By H-1-Mr Spectroscopy in Early-Onset Multiple Sclerosis
(Amer Soc Neuroradiology, 2009)
BACKGROUND AND PURPOSE: Myelin instability and citrullinated myelin basic protein have been demonstrated in the brains of patients with chronic and fulminating forms of multiple sclerosis (MS). Our aim was to trace citrulline ...
Endothelial Nitric Oxide Synthase-Dependent Cerebral Blood Flow Augmentation By L-Arginine After Chronic Statin Treatment
(Sage Publications Inc, 2000)
Nitric oxide, a product of nitric oxide synthase activity, relaxes vascular smooth muscle and elevates brain blood flow. We evaluated the importance of eNOS to cerebral blood flow augmentation after L-arginine infusion and ...
Blockade of Gaba Synthesis Only Affects Neural Excitability Under Activated Conditions in Rat Hippocampal Slices
(Pergamon-Elsevier Science Ltd, 2008)
The primary goal of this study was to establish whether inhibition of GABA synthesis was sufficient to induce network hyperexcitability in a rat hippocampal slice model comparable to that seen with GABA receptor blockade. ...
Creatine Kinase-Mb Elevation After Stroke Is Not Cardiac In Origin - Comparison With Troponin T Levels
(Lippincott Williams & Wilkins, 2002)
Background and Purpose-Creatine kinase-MB (CK-MB) increases in some patients with stroke, with no clear evidence of an acute coronary syndrome. Its elevations have been suggested to represent a biological marker for ...
Role of Endothelial Nitric Oxide Generation and Peroxynitrite Formation in Reperfusion Injury After Focal Cerebral Ischemia
