PURPOSES Morphine can induce tolerance and hyperalgesia after long-term administration. Glial activation is believed to cause and maintain a state of morphine-induced pain hypersensitivity. The present study examines the effect of melatonin on tolerance, hyperalgesia, and reactive gliosis induced by morphine in rats. METHODS The study examines the effect(More)
Transportation management and planning has played an important role in urban planning. The paper discusses the success of using virtual reality (VR) technique in traffic simulation to communicate design alternatives to decision makers and public audiences and thus to support the decision making process. The study documents the application of VISSIM, a(More)
The agriculture machinery guidance technology is one of precision agricultural important technologies. Based on GPS and GIS, it can raise working efficiency and improve the quality, reduce production costs, reduce driver working difficulty. This research's general goals realize the aided guidance function for agriculture machinery driving on road and(More)
To investigate the protecting effects of dexamethasone (DXM), baicalin and octreotide on brain injury of rats with severe acute pancreatitis (SAP) and explore their underlying mechanism. This experiment was divided into two different parts: (1) In the first part, 90 SAP rats were randomly divided into a model control group and a DXM treated group (n = 45,(More)
Introduction: SuperBots represent a departure from the paradigm of single purpose robots for single missions to a more mature and evolved philosophy that emphasizes multifunctionality, modularity, and reconfigurability [1]. The SuperBot system consists of a set of interlocking autonomous robotic modules that can self-reconfigure into different systems for(More)
Introduction: Robotic systems are essential for space and lunar exploration. They perform tasks that range from inspection, maintenance, and assembly in space, to scientific exploration, transportation, habitat construction, resource utilization, and astronaut assistant on planetary surface. However, the traditional approach of building special robots for(More)
Introduction: SuperBots are modular, multifunctional, and reconfigurable robots [1]. They are an elegant example of "design for reuse" that can reduce cost and payload mass while enhancing mission performance, reliability, and safety through their ability to change shape and function as needed. Constructed of autonomous, intelligent, and self-reconfigurable(More)
MicroRNAs (MiRNAs) are a class of small non-coding regulatory RNAs that repress protein expression at the posttranscriptional level and play important roles in hematopoiesis processes. MiR-146a is a miRNA that is thought to regulate physiological and pathophysiological pathways in hematopoietic cells. In this review, we focus on recent progress in analyzing(More)
The purpose of this study is to investigate the efficacy and safety of recombinant erythropoietin-beta in the treatment of anemic patients with multiple myeloma (MM), low-grade non-Hodgkin's lymphoma (NHL), and chronic lymphocytic leukemia (CLL). From December 2005 to November 2006, the patients with MM, low-grade NHL, and CLL were enrolled in this study,(More)
