Nogo is a potent inhibitor of regeneration following spinal cord injury. To develop a better understanding of the mechanisms responsible for regenerative failure we used a yeast two-hybrid approach to try and identify proteins that interact with Nogo. We identified a novel mitochondrial protein designated Nogo-interacting mitochondrial protein (NIMP) in a(More)
The effect of 17beta-estradiol on the secondary damage following spinal cord injury (SCI) was examined in male rats subjected to moderate compression. Two doses of 17beta-estradiol (0.1 or 4 mg/kg) were injected i.p. immediately after spinal cord compression. Functional outcome was observed during 4 weeks following injury with two different tests.

Traumatic spinal cord injury (SCI) disrupts the blood-spinal cord barrier and reduces the blood supply caused by microvascular changes. Vessel regression and neovascularization have been observed in the course of secondary injury contributing to microvascular remodeling after trauma. Spatio-temporal distribution of blood vessels and modulation of gene(More)
Symptomatic anterior or anterolateral dural herniation of the spinal cord is rare, and not uncommonly misdiagnosed, both clinically and radiologically. We present four patients with a radiological diagnosis of herniation of the thoracic spinal cord, and review the current literature. All affected patients have been adults, typically presenting with(More)
Disruption of the blood-spinal cord barrier (BSCB) and microvascular changes leading to reduction of blood supply represent hallmarks of spinal cord secondary injury causing further deterioration of the traumatized patient. Injury to the blood vessels starts with prominent hemorrhage and generation of inflammation. Furthermore, spinal cord ischemia and(More)
The influence of the blood-brain barrier (BBB) on tracer uptake was investigated in 21 patients with gliomas and meningiomas using PET, [18F]fluorodeoxyglucose (FDG), [18C]methionine (MET) and the K+ analog rubidium-82 (RUB) whose uptake into brain is largely prevented if the BBB is intact. Tracer uptake was quantitated by (1) multiple time graphical(More)
As proinflammatory cytokines seem to play a role in discogenic back pain, substances exhibiting anti-inflammatory effects on intervertebral disc cells may be used as minimal-invasive therapeutics for intradiscal/epidural injection. The purpose of this study was to investigate the anti-inflammatory and anti-catabolic potential of curcuma, which has been used(More)
RGS proteins regulate G protein-mediated signalling pathways through direct interaction with the Galpha subunits and facilitation of GTP hydrolysis. An RGS subfamily consisting of RGS 6, 7, 9, and 11 also interacts with the G protein beta subunit Gbeta5 via a characteristic Ggamma-like domain. Thus far, these complexes were found only in neurons, with RGS7(More)
Vertebrobasilar ectasia is a rare cause of typical trigeminal neualgia. In a recently published large series only thirty-one (2%) of 1404 consecutive patients with vascularly determined neuralgia were found to have vertebrobasilar compression. We present three patients with trigeminal neuralgia caused by vertebrobasilar ectasia, who were evaluated with high(More)
