The present study investigated the effects of glycyrrhizin (GRZ) on neuroinflammation and memory deficit in systemic lipopolysaccharide (LPS)-treated C57BL/6 mice. Varying doses of GRZ was orally administered (10, 30, or 50 mg/kg) once a day for 3 days before the LPS (3 mg/kg) injection. At 24 h after the LPS injection, GRZ significantly reduced TNF-α and(More)
Biomedical signals such as ECG, EMG, and EEG are extremely important in the diagnosis of patients. It is difficult to filter noise from these signals, and errors resulting from filtering can distort a biomedical signal. Existing systems have shown poor performance when complicated noise appears. Adaptive filtering is selected to contend with these defects.(More)
We investigated the associations of periventricular white matter hyperintensities (PWMHs) and deep white matter hyperintensities (DWMHs) with cognition, activities of daily living (ADLs), and neuropsychiatric symptoms in dementia. This was a hospital-based MRI300 study. We recruited patients newly diagnosed with mild-to-moderate dementia caused either by(More)
Commercial lower limb prostheses or orthotics help patients achieve a normal life. However, patients who use such aids need prolonged training to achieve a normal gait, and their fatigability increases. To improve patient comfort, this study proposed a method of predicting gait angle using neural networks and EMG signals. Experimental results using our(More)
BACKGROUND Static wrist splinting after stroke was not effective in facilitating distal movement. However, the purpose of this study is to evaluate the efficacy of training using kinematic parameters after a SaeboFlex orthosis training on chronic stroke patients. CASE DESCRIPTION AND METHODS Five stroke patients participated in 4 weeks of training using a(More)
