Bell's palsy (BP), a unilateral and idiopathic palsy of the facial nerve, is a common disorder generally followed by a good natural recovery. The aim of this study was to investigate the relationship between the functional connectivity of the anterior cingulate cortex (ACC) and the recovery process of BP. Thirty-seven healthy volunteers and 67 patients were(More)
Bell's palsy is the most common cause of acute facial nerve paralysis. In China, Bell's palsy is frequently treated with acupuncture. However, its efficacy and underlying mechanism are still controversial. In this study, we used functional MRI to investigate the effect of acupuncture on the functional connectivity of the brain in Bell's palsy patients and(More)
Acupuncture is widely used in the treatment of Bell's palsy (BP) in many countries, but its underlying physiological mechanism remained controversial. In order to explore the potential mechanism, changes of functional connectivity (FC) of anterior cingulate gyrus (ACC) were investigated. We collected 20 healthy (control group) participants and 28 BP(More)
We use electrospinning to fabricate sperm-shaped magnetic microrobots with a range of diameters from 50 μm to 500 μm. The variables of the electrospinning operation (voltage, concentration of the solution, dynamic viscosity, and distance between the syringe needle and collector) to achieve beading effect are determined. This beading effect(More)
Motor imagery (MI) has attracted increased interest for motor rehabilitation as many studies have shown that MI shares the same neural networks as motor execution (ME). Nevertheless, MI in terms of facial movement has not been studied extensively; thus, in the present study, we investigated shared neural networks between facial motor imagery (FMI) and(More)
An experimental investigation was conducted to study supersonic jets from convergent divergent nozzles with rectangular cross section. The flow regimes and shock structure in the plume was characterized for jets in quiescent atmosphere at over-expanded conditions. Schlieren pictures of the jets are presented to show the shock structure and jet spread rate(More)
