The strategy of mesenchymal stem cells (MSCs) transplantation is limited by the inability to deliver a large number of grafted cells that resist peri-transplantation apoptosis in ischemic tissues, and this led us to investigate methods of improving the viability of these cells. We demonstrate the presence of voltage-gated potassium channels in rat MSCs that(More)
AIMS To determine the HIV-1 seroprevalence, risk behaviors and demographic characteristics associated with HIV-1 infection among injection drug users (IDU) in rural Guangxi, China. DESIGN AND SETTING Between July and November 2002, 702 IDU were screened for HIV-1 antibody through community outreach in rural Guangxi, China for enrollment in an HIV(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)
A novel image recognition system is constructed by combining Wavelet invariant moments with Wavelet neural networks in this paper. Firstly, global and local features of the image can be obtained by using Wavelet invariant moments. Secondly, the invariant features are fed into Wavelet neural networks. Finally, supervised invariant pattern recognition can be(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)
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)
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)
