Anesthesia was induced with sevoflurane via facemask, intravenous access times two was established and the trachea was intubated. A radial arterial line was placed for hemodynamic monitoring and serial arterial blood gas analysis. Anesthetic maintenance proceeded with propofol and remifentanil infusions and half MAC desflurane to facilitate neuromonitoring. Baseline SSEP and MEP signals were ob...

Image classification is a well known of the significant tools used to recognize and examine most sharp information in satellite images. In any remote sensing research, the decision-making way mainly rely on the efficiency of the classification process. There are disparate classification algorithms on the large satellite imagery: Multilayer perceptron back propagation neural network (MLP BPNN), ...

STUDY DESIGN Systematic review and meta-analysis. OBJECTIVE The aim of this study was to systematically evaluate the diagnostic utility of intraoperative neurophysiological monitoring (IONM) for detecting postoperative injury in resection of intramedullary spinal cord tumors (IMSCT). SUMMARY OF BACKGROUND DATA Surgical management of IMSCT can involve key neurological and vascular structures...

The large deviation (LD) statistics of dynamical observables is encoded in the spectral properties deformed Markov generators. Recent works have shown that tensor network methods are well suited to compute relevant leading eigenvalues and eigenvectors accurately. However, efficient generation corresponding rare trajectories a harder task. Here we show how exploit MPS approximation dominant eige...

We have studied the ability of nonionic detergents and hydrophilic polymers to seal permeabilized membranes of damaged cells, rescuing them from progressive dissolution, degeneration, and death. We report that a single subcutaneous injection of the tri-block copolymer, Poloxamer 188 (P188) 6 hr after a severe compression of the adult guinea pig spinal cord is able to: (1). preserve the anatomic...

Abstract Background There is growing evidence of the valuable role multimodal intraoperative neurophysiological monitoring (IONM) during spine and spinal cord surgeries, as it provides an opportunity to recognize functional changes neural elements, usually in reversible stage, complex surgical manipulations. Therefore, may reduce risk postoperative neurological dysfunction improve outcomes. The...

BACKGROUND/AIM Diagnostic protocol for patients with degenerative diseases of the cervical spine demands, in parallel with neuroimaging methods, functional evaluation through neurophysiological methods (somatosensitive and motor evoked potentials and electromyoneurography) aiming to evaluate possible subclinical affection of spinal medula resulting in neurological signs of long tract abnormalit...

BACKGROUND Somatosensory (SSEP) and brainstem auditory (BAEP) evoked potentials are neurophysiological tools which, respectively, explore the intracranial conduction time (ICCT) and the intrapontine conduction time (IPCT). The prognostic values of prolonged cerebral conduction times in deeply sedated patients have never been assessed. Sedated patients are at risk of developing new neurological ...

Objectives—To verify the applicability and validity of time-frequency analysis (TFA) of evoked potential (EP) signals in detecting the integrity of spinal cord function and preventing spinal cord injury. Methods—The spinal cord was simulated during surgery in 20 mature rats by mechanically damaging the spinal cord. Cortical somatosensory evoked potential (CSEP), spinal somatosensory evoked pote...
