UNLABELLED The aim of this study was to investigate if sequential analysis of BOLD signal changes induced by seizures is useful for preoperative identification of the site of seizure onset in patients with pharmaco-resistant focal epilepsy. METHOD We analyzed BOLD raw data from 5 patients with focal medically refractory epilepsy who experienced partial(More)
We present one patient with Parry Romberg syndrome and another with linear scleroderma in coup de sabre, with focal neurologic deficits and intractable seizures arising from the hemisphere ipsilateral to the cutaneous lesion. Brain MRI showed progressive hemispheric atrophy. Pathology after functional hemispherectomy showed chronic inflammatory features(More)
INTRODUCTION Functional hemispherectomy is a surgical technique used to treat refractory epilepsies in the setting of extensive unilateral hemispheric lesions. Most series of hemispherectomies include mainly pediatric patients. METHODS We report our series of four adult patients that have undergone functional hemispherectomy for their refractory epilepsy.(More)
Following the recently developed approach to the solution structure of paramagnetic high-potential iron-sulfur proteins, the three-dimensional structure in solution of the oxidized Clostridium pasteurianum ferredoxin has been solved by 1H-NMR. The X-ray structure is not available. The protein contains 55 amino acids and two [4Fe-4S] clusters. In the(More)
We investigated the clinical features and surgical outcome of 17 patients with refractory epilepsy secondary to CNS infection who were referred to a tertiary center for presurgical evaluation. Six patients had a history of meningitis and 11 patients had a history of encephalitis. Median age at infection was three years (40 days-40 years). Time to seizure(More)
Haloferax mediterranei is a halophilic archaeon that can grow in aerobic conditions with nitrate as sole nitrogen source. The electron donor in the aerobic nitrate reduction to ammonium was a ferredoxin. This ferredoxin has been purified and characterised. Air-oxidized H. mediterranei ferredoxin has a UV-visible absorption spectra typical of 2Fe-type(More)
The blue copper proteins (BCPs), pseudoazurin from Achromobacter cycloclastes and rusticyanin from Thiobacillus ferrooxidans, have been investigated by (1)H NMR at a magnetic field of 18.8 T. Hyperfine shifts of the protons belonging to the coordinated ligands have been identified by exchange spectroscopy, including the indirect detection for those(More)
Substitution of copper by cobalt in blue copper proteins gives a paramagnetic metalloderivative suitable for paramagnetic NMR studies. A thorough analysis of the 1H-NMR spectrum of Pseudomonas aeruginosa Co(II)-azurin is presented here. All the observable contact-shifted signals as well as many other paramagnetic signals from protons placed up to about 1.0(More)
The orientation and the axial, Deltachiax, and rhombic, Deltachirh, components of the magnetic susceptibility tensor anisotropy for the cobalt(II) and nickel(II) derivatives of azurin from Pseudomonas aeruginosa have been determined from 1H NMR data. For both derivatives, the axial geometry of the system determines the orientation of the chi-tensor, whose(More)
