A Closed-loop Brain-computer Interface for Stroke
It may be hard to acquire stable sensorimotor rhythm from the affected motor cortex for patient without a response of paretic hand. A few studies suggest two ways to approaching closed-loop therapy: peripherally extracting the residual signals, for example electromyogram (EMG) at proximal muscles (deltoids) and centrally extracting the activity …

Systematic Assessment of SARS-CoV-2 Neurotropic Capacity in Modestly and Critically Ill Patients and Patients Who Died From COVID-19
This study is to analyze the microglia reaction or direct neurotropic effects of CNS COVID-19 in pathogenesis and brain stem dysfunction in critically ill patients. A microglia-focused, brain-specific 50+ marker CODEX panel is used to assess the neuroinflammatory microenvironment in specific brain regions of deceased COVID-19 patients. The peripheral (cerebrospinal …

Qualitative and Quantitative Evaluation of Vascular Flows of Radial Ulnar and Interdigital Arterial Trees Under Normal and Pathological Conditions by 3 Tesla MRI
Between 2015 and 2017, several acquisitions were made in 3 patients who received facial allotransplantation, and the team recently developed a flow MRI protocol dedicated to the study of arterial trees in the hand. The main objective is to measure vascular flows of radial, ulnar and interdigital arterial trees in …

Assessment of Paravalvular Leak After TAVI by Hemodynamic Measurements and Cardiac MRI
Echocardiography and angiography systematically underestimate paravalvular leakage (PVL) as compared to cardiac MRI. Hemodynamic measurements are used to aid decision making directly after TAVI implantation. Prospective data comparing hemodynamic measurements with cardiac MRI are needed to design an optimal strategy to grade paravalvular leakage peri-operatively in order to optimize TAVI …
