background: in vitro fertilization and embryo transfer (ivf-et) is the best option for patients with hydrosalpinx. however, if hydrosalpinges is not pre-treated, the therapeutic outcomes of ivf-et would be compromised. objective: this study aims to investigate the safety and effects of operative hysteroscopy in the treatment of patients with hydrosalpinx prior to ivf-et, who were not indicated ...

The stability of mandibular complete dentures may be improved by reducing the transverse forces on the denture base through linear (noninterceptive) occlusion, selecting an occlusal plane that reduces horizontal vectors of force at occlusal contact, and utilizing a central bearing intraoral gothic arch tracing to record jaw relations. This article is intended to acquaint the reader with one tec...

We present several techniques for user-centric viewing of the virtual objects or datasets under haptic exploration and manipulation. Depending on the type of tasks performed by the user, our algorithms compute automatic placement of the user viewpoint to navigate through the scene, to display the near-optimal views, and to reposition the viewpoint for haptic visualization. This is accomplished ...
