The roles of endogenous opioid peptides in the brain in the modulation of nocifensive responses to formalin in ICR mice were studied. Mice were pretreated intracerebroventricularly (i.c.v.) with rabbit antiserum against beta-endorphin, [Leu5]enkephalin, [Met5]enkephalin or dynorphin A-(1-17) 1 h prior to intraplantar injection of formalin (0.5%, 25 microl)(More)
Development of tolerance in mice pretreated intracerebroventricularly with mu-opioid receptor agonist endomorphin-1, endomorphin-2, or [D-Ala(2),N-Me-Phe(4),Gly-ol(5)]-enkephalin (DAMGO) was compared between endomorphin-1- and endomorphin-2-induced antinociception with the tail-flick test. A 2-h pretreatment with endomorphin-1 (30 nmol) produced a 3-fold(More)
This paper introduces a new design to allow interactive, direct manipulation of volume data on volumetrically rendered images. We present an adaptive volume proxy mesh which serves not to define surfaces, but to encode the geometry and physical state of the volume. This system performs a modeling-free form of direct volume deformation by adaptively(More)
PURPOSE Patient-specific surgical simulation imposes both practical and technical challenges. We propose a segmentation-free, modeling-free framework that creates medical volumetric models for intuitive volume deformation and manipulation in patient-specific surgical simulation. METHODS The proposed framework creates a volumetric model based upon a new(More)
— This thesis is to present a new approach for license-plate recognition using 2D Haar Discrete Wavelet Transform (HDWT) and Artificial neural Network. This thesis consists of three main parts. The first part is to locate and extract the license-plate in an image. The second part is to train of the license-plate. The third part is to real time scan(More)
Patient-specific, interactive surgical simulation has become a major research direction in the biomedical side of computer graphics. While performing deformation on patients' medical volume data provides a realistic venue to define the most suitable operative strategy, the current simulators rely heavily on human efforts for data preprocessing. Such manual(More)
—The nondestructive detection of defects in multilayer ceramic capacitors (MLC's) in surface mount printed circuit board assemblies has been demonstrated by using an improved digital speckle correlation method (DSCM). The internal cracks in MLC's that contribute to the thermal displacements on the MLC surface after dc electrical loading may be uniquely(More)
