For further morphological and physiological research, it is vital to establish precise three-dimensional models of the whole inner ear including the details of the membranous components. With the system of a projector and a high-resolution digital camera, 2 complete serial unstained celloidin sections of fresh human temporal bones were digitized as(More)
To investigate the interaction between stereocilia and the links of inner hair cells during the motion of the organ of Corti and local stress distribution, two 3D finite-element models were built. Static and dynamic simulation results showed that the top of stereocilia at the intermediate row might be a key location for activating gated ion channels.
AIMS Sildenafil, a phosphodiesterase type 5 inhibitor, has been found to produce functional recovery in ischemic rats by increasing the cGMP level and triggering neurogenesis. The aim of this study was to investigate further sildenafil mechanisms. METHODS Male Sprague-Dawley rats underwent middle cerebral artery occlusion and reperfusion, followed by(More)
Four Stachybotrys strains were isolated from soil in China. One was identified as a novel species by morphological characters of phialides and conidia. It produced cylindrical conidia with irregular striations and smooth, hyaline conidiophores. Phylogenetic analysis of three DNA markers, the internal transcribed spacer region of rDNA (ITS1–5.8S–ITS2), the(More)
It is very important to predict displacements and deformations of the vessels near tumor before actinotheraphy or surgery. To simulate the influence to blood vessel induced by tumor growth, cellular automata is employed to simulate the tumor growth, and the tumor geometrical model is meshed to construct the finite element model with tetrahedron cells.

This article presents a method for developing anatomic contour maps that quantitatively display the vestibular apparatus's 3D spatial configurations. Contour maps are useful tools for determining the appropriate position of the drill and the safe depth and orientation of the installed piston in stapedotomy procedures
The purpose of this study was to determine the quantitative relationships between the positions of the sigmoid sinus (SS) and jugular bulb (JB) and the influence of mastoid pneumatization upon these structures. The investigations were carried out on 116 healthy adult ears based on the axial images of computed tomography (CT). The reference system locating(More)
