Chronic cerebral hypoperfusion (CCH) increases the risk of Alzheimer disease (AD) through several biologically plausible pathways, but the relationship between CCH and the development of AD remains uncertain. To investigate expression of APP, BACE1 and Aβ in the hippocampus of BCCAO rats and study pathophysiological mechanism of AD from CCH. CCH rat model(More)
A large amount of organophosphate pesticides (OPs) is used throughout China. Animal studies have suggested that even moderate doses are toxic to neurodevelopment, but there are a few studies in humans. We investigated both the urinary levels of OP metabolites in children and their relationship with child neurodevelopment. Participating 301 young children(More)
PURPOSE Cyst excision with hepaticojejunostomy has been the classic procedure for treating choledochal cysts. Recently, laparoscopic treatment of the disease has gained popularity worldwide. The aim of this study is to evaluate whether laparoscopic management of choledochal cysts is as feasible and safe as conventional open surgery in children with this(More)
AIM The present study investigated the processes of macrogametogenesis and oocyst formation of Eimeria tenella (Xiamen strain), including the formation of wall-forming body1 (WFB1) and wall-forming body 2 (WFB2), the club-shape body and the origin of the residual body during the transformation from a macrogamete to an oocyst. METHOD Transmission electron(More)
OBJECTIVE The aim of this study was to compare the epidemiological results of children with burns among different decades from 1970 to 2008. METHODS The clinical data of all children with burns younger than 14 years admitted between 1970 and 2008 were compared among different decades using Statistical Package for Social Sciences (SPSS). RESULTS Of all(More)
Filter bank is the most common feature being employed in the research of the marginalisation approaches for robust speech recognition due to its simplicity in detecting the unreliable data in the frequency domain. In this paper, we propose a hybrid approach based on the marginalisation and the soft decision techniques that make use of the Mel-frequency(More)
To improve the performance of route overhead and packet dropped rate of routing algorithms in mobile ad hoc networks, a location-based grid routing (LBGR) algorithm is presented. By node position information, the LBGR algorithm employs a grid-constructed trajectory instead of node ID in forwarding packets. Based on the position relationship of nodes and(More)
Currently, the Civil Aviation Administration of China (CAAC) is developing a promising new surveillance technology Automatic Dependent Surveillance-Broadcast (ADS-B) in western China, with the aim of resolving the lack of surveillance methods there caused by the complex terrain and costly maintenance. By virtue of ADS-B technology, more timely, accuracy and(More)
OBJECTIVE The purpose of this study was to characterize the magnetic resonance imaging (MRI), and computed tomographic (CT) findings in a series of 8 patients with papillary glioneuronal tumor (PGNT). METHODS The routine MRI (n = 8), DWI (n = 7), and CT (n = 4) of 8 PGNTs verified by pathologic examination were reviewed. The location, internal(More)
BACKGROUND/PURPOSES Laparoscopy has been widely accepted as a technique for the excision of choledochal cyst, but there has been little experience using it as a therapeutic modality for hepatic duct stenosis. The aim of this study is to present our experiences in laparoscopic excision of biliary stenosis and Roux-en-Y reconstruction for patients with(More)
