OBJECTIVE Receptor-associated protein (RAP) was initially described as a regulator of low density lipoprotein receptor-related protein 1 (LRP1), but is now known to regulate many proteins. Since the direct effects of RAP on vascular pathologies have not been studied, this study determined whether RAP deficiency influenced angiotensin II (AngII)-induced(More)
BACKGROUND It is unclear whether selective infarct-related artery (sIRA) administration of glycoprotein IIb/IIIa receptor inhibitors (GPI) may further improve myocardial reperfusion without increasing bleeding in patients with ST-elevation myocardial infarction (STEMI). The aim of this study was to compare the impacts of sIRA infusion with conventional(More)
BACKGROUND A prospective observational study of HIV seroincidence among high-risk injection drug users (IDU) was carried out in Guangxi, China. The primary objectives of this study were (1) to estimate HIV seroincidence (2) to estimate participant retention rate and (3) to evaluate changes in drug use and sexual behavior over a one year period. METHODS(More)
Besides the hardware/software failure of switched Ethernet, the capability of data transmission affects its performance and reliability. After summarizing the influence factors of Ethernet service capability, this paper focuses on the time delay oriented reliability model and analysis method. Based on the operational mechanism analysis of Avionics Full(More)
This is the second part of a series papers on modeling and path planning of the City-Climber robot. This paper presents a path planning method for the City-Climber robot using mixed integer linear programming (MILP) in 3D building environments that consist of objects with primitive geometrical shapes. In order to use MILP to solve obstacle avoidance(More)
