Demyelinating pseudotumor is a rare inflammatory demyelinating disease of the central nervous system (CNS) that has a similar clinical presentation and computed tomography (CT) and magnetic resonance imaging (MRI) imaging findings as brain tumors or abscesses. Unlike brain tumors, demyelinating pseudotumors respond well to steroid hormones. There are only a(More)
PURPOSE Drug resistance has been recognized to be a major obstacle to the chemotherapy for osteosarcoma. And the potential importance of hypoxia as a target to reverse drug resistance in osteosarcoma has been indicated, though the mechanism underlining such role is not clarified. The present study aims to investigate the role of hypoxia in the drug(More)
Tensile stress and tensile strain directly affect the quality of nerve regeneration after bridging nerve defects by poly(lactic-co-glycolic acid) conduit transplantation and autogenous nerve grafting for sciatic nerve injury. This study collected the sciatic nerve from the gluteus maximus muscle from fresh human cadaver, and established 10-mm-long sciatic(More)
The paper presents a novel method to sketch in 3D for automotive styling based on a computer-aided styling system — AutoSketch, which has been prototyped by using ThinkDesign API. Differing from the traditional CAS/CAD systems, AutoSketch uses a digital pen to draw/sketch in a natural way on digital tablet/screen to create 3D surface models. The(More)
