OBJECTIVE: In symptomatic unruptured intracranial aneurysms (UIA), data on long-term functional outcome are sparse in the literature, even in the light of modern interdisciplinary treatment decisions. We therefore analysed our in-house database for prognostic factors and long-term outcome of neurological symptoms after microsurgical/endovascular treatment. METHODS: Patients treated between 2000 and 2016 after interdisciplinary vascular board decision were included...

The objective of the study is to investigate the clinical features of Behçet's disease (BD) complicated with cerebral venous sinus thrombosis (CVST). We retrospectively analyzed the clinical features of age- and gender-matched BD patients with and without CVST. Of the 840 BD patients enrolled, 21 (2.5%, 11 female, mean age 30.3 ± 9.5) were diagnosed as CVST. Eighteen patients (85.7%) developed neurologic manifestations after BD onset, with an average interval of 47.6 months (SD 36.1). Onset of neurologic symptoms was mostly progressive (89...

Post-stimulus undershoots, negative responses following cessation of stimulation, are widely observed in functional magnetic resonance (fMRI) blood oxygenation level dependent (BOLD) data. However, the debate surrounding whether the origin of this response phase is neuronal or vascular, and whether it provides functionally relevant information, that is additional to what is contained in primary response, means that undershoots are widely overlooked. We simultaneously recorded electroencephalography (EEG), BOLD and cerebral blood-flow (CBF) [obtained from arterial spin labelled (ASL) fMRI] fMRI responses to hemifield checkerboard stimulation to test the potential neural origin of the fMRI post-stimulus undershoot...

BACKGROUND: The phenolic substance resveratrol (RES) is a plant metabolite known to modulate numerous physiological functions and to exert beneficial effects as a cancer-chemopreventing agent and on neurological, hepatic, and cardiovascular systems. Since the compound affects the lifespan of yeast and flies it might be an anti-aging substance. Mechanistically, RES is involved in down regulating the inflammatory response. The pleiotropic effects of RES in cells of the immune and endothelial system were examined in this study...

Cerebral malaria (CM) is a severe neurological complication of malaria infection in both adults and children. In pursuit of effective treatment of CM, clinical studies, postmortem analysis and animal models have been employed to understand the pathology and identify effective interventions. In this study, a shotgun proteomics analysis was conducted to profile the proteomic signature of the brain tissue of mice with experimental cerebral malaria (ECM) in order to further understand the underlying pathology. To identify CM-associated response, proteomic signatures of the brains of C57/Bl6N mice infected with P...
