W e describe a patient with chorea-acanthocytosis who showed dist ributed nemalin e rods in biopsied muscle. It has been suggested that in chorea-acanthocytosis, the muscle membranous structures are disordered, and our finding may be attribu table to this underlying myopathic condition.展开更多

The present bubble model is based on the so-called Rayleigh-Plesset equation that calculates a temporal bubble radius with the surrounding liquid pressure and is considered to be valid in an area below a certain void fraction. The solution algorithm is modified so that the Rayleigh-Plesset equation is no more solved once the bubble radius （or void fraction） reaches at a certain value till the liquid pressure recovers above the vapor pressure in order to overcome this problem. This procedure is expected to stabilize the numerical calculation. The results of simple two-dimensional flow field are presented compared with the existing bubble model.展开更多
