Objective: Peri-infarct Depolarizations (PIDs) are a type of spreading Depolarization (SD) that has been linked to infarct volume expansion following an ischemic stroke. Therapeutic hypothermia has been found to provide a neuroprotective effect after an ischemic stroke and may improve outcomes. Therefore, [for full text, please go to the a.m. URL]

Objective: Since the first description by Nevin and Kiloh the compression syndrome of anterior interosseous nerve has been the subject of controversial discussion. Recently, the use of MR-neurography (MRN) and high-resolution neurosonography (HRNS) spawned the idea of neuritis as only agent causing [for full text, please go to the a.m. URL], 72.

Objective: Spreading Depolarization (SD) occurs frequently after malignant hemispheric stroke (MHS) and may promote lesion growth. In the experimental setting, several physiologic parameters were shown to influence SD and its features. In this study we analyzed the impact of temperature (T°), intracranial[for full text, please go to the a.m. URL], 71. Jahrestagung der Deutschen Gesellschaft für Neurochirurgie (DGNC), 9.

Objective: Over the last years, endothelial cells (ECs) have come into scientific focus in peripheral nerve research, as they were shown to be a major constituent of the blood-nerve-barrier (BNB) and provide axonal guidance in peripheral nerve regeneration. However, mainly animal models and commercially[for full text, please go to the a.m. URL], 71. Jahrestagung der Deutschen Gesellschaft für Neurochirurgie (DGNC), 9.

Objective: Navigated pedicle screw placement can be performed using intraoperative computerized tomography (CT) or digital volume tomography (DVT). An additional benefit of using high-resolution intraoperative imaging, such as DVT, is the possibility to immediately assess screw placement with the chance[for full text, please go to the a.m. URL], 71.

Objective: Spreading depolarization (SD) occurs in high frequency in patients with malignant hemispheric stroke (MHS) and is coupled to different hyperaemic or hypoaemic blood flow responses. Body temperature is a major trigger for SDs and influences the accompanied flow coupling. Here, we investigated[for full text, please go to the a.m. URL], 69.

Objective: Formerly we characterized the process of spontaneous collateral remodeling (arteriogenesis) in a model of chronic cerebral hypoperfusion. Recent evidence in the field of peripheral artery and coronary heart disease research suggests that this process is accompanied by upregulation of the [for full text, please go to the a.m. URL], 69.

Objective: Recently, we characterized cerebral arteriogenesis in a mouse model of chronic cerebral ischemia. However, proximal vessel occlusion in cerebral hemodynamic compromise is usually caused by atherosclerotic cerebrovascular disease.

Objective: Spreading depolarization (SD) occurs in high frequency in patients with malignant hemispheric stroke (MHS) and is coupled either to hyperaemic or hypoaemic blood flow responses. After experimental focal ischaemia SD is a significant cause for secondary stroke progression during the initial[for full text, please go to the a.m. URL], 68.

Objective: The primary objective of this study was to compare the results of two different sacropelvic fixation techniques to conventional stabilization to the sacrum. Our focus were patients with multilevel degenerative spine disease and the need for a multilevel correction and stabilization with a[for full text, please go to the a.m. URL], 65.

Objective: Current intraoperative monitoring techniques lack adequate surveillance of cerebral blood flow (CBF). Laser Speckle Imaging (LSI) can be used for non-invasive and direct assessment of cortical perfusion.
