Design of a symmetry controller for cycling induced by electrical stimulation: preliminary results on post-acute stroke patients.

abstract：:The feasibility of extracorporeal adsorption of 1.5-3 L plasma on protein A-Sepharose was investigated in six patients with advanced cancer. Anticoagulation with heparin was associated with respiratory distress syndrome in two patients, most likely caused by complement activation as indicated by a transient leukopenia...
