Mesenchymal stem cells (MSCs) reside in almost all of the body tissues, where they undergo self-renewal and multi-lineage differentiation. MSCs derived from different tissues share many similarities but also show some differences in term of biological properties. We aim to search for significant differences among various sources of MSCs and to explore their(More)
BACKGROUND Mesenchymal stem cells (MSC) play important roles in modulating the activities of T lymphocytes, dendritic cells and natural killer cells. These immunoregulatory properties of MSC suggest their therapeutic potential in autoimmune diseases. However, the effects of MSC on B cells are still poorly understood. The present study was designed to(More)
Two recombinant fowlpox viruses (rFPV-P1 and rFPV-IL18-2AP12A) containing foot-and-mouth disease virus (FMDV) capsid polypeptide, 3C coding regions of O/NY00 were evaluated to determine their abilities to induce humoral and cellular responses in the presence or absence of swine IL-18 as genetic adjuvant. The ability to protect swine against homologous virus(More)
The assessment of binding affinity between ligands and the target proteins plays an essential role in drug discovery and design process. As an alternative to widely used scoring approaches, machine learning methods have also been proposed for fast prediction of the binding affinity with promising results, but most of them were developed as all-purpose(More)
BACKGROUND The generation of antibodies (anti-HBe) against hepatitis B virus (HBV) e antigen (HBeAg) often coincides with clinical remission in chronic HBV patients. We aimed to examine the effect of maternal anti-HBe in protection against HBV mother-to-child transmission (MTCT). METHODS A total of 140 chronic HBV-infected pregnant women participated in(More)
BACKGROUND/AIMS Human umbilical cord mesenchymal stem cells (hUC-MSCs) possess immunosuppressive activities but the mechanisms of such activities are not fully understood. Here, we investigated the role of IL-6, one of the characteristic factors of MSCs, in the immunoregulating effect of hUC-MSCs on CD4(+) T lymphocytes. METHODS The condition media from(More)
DNA-based vaccination is an attractive alternative for overcoming the disadvantages of inactivated virus vaccines; however, DNA vaccines alone often generate only weak immune responses. In this study, the efficacy of LMS as a chemical adjuvant on a DNA vaccine (pVIR-P12A-IL18-3C) encoding the P1-2A and 3C genes of the FMDV and swine IL-18, which provides(More)
Over the past decades, more and more online resources are provided as the primary teaching medium, or as a forum for knowledge networking and discussion, or information exchange with peers or experts. In the field of music education, online education offers much convenience to learners, and satisfies them with difference demands, which inevitably attracts(More)
With the development of network technology, more and more data are transmitted over the network and privacy issues have become a research focus. In this paper, we study the privacy in health data collection of preschool children and present a new identity-based encryption protocol for privacy protection. The background of the protocol is as follows. A(More)
OBJECTIVE To prepare a new Wubei fast-release tablet and study the pharmacokinetics and bioequivalence of self-prepared Wubei fast-release tablet and Wubei powder in Beagle dogs. METHOD Wubei fast-release tablet was prepared with direct powder compression. Six Beagle dogs were randomly devided into two groups. They were orally administered with Wubei(More)
