The study was to understand the Angiostrongylus cantonensis infectious situation of rodent definitive host, snail intermediate host, and local residents in the west-central region of Guangdong Province in China. The snails Achatina fulica and Pomacea canaliculata collected from the survey place were digested with artificial gastric juice, and the(More)
The immune responses of Angiostrongylus cantonensis infection are closely relevant to the host’s self-protection and the nematode’s pathogenesis. In the present study, BALB/c mice were randomly divided into uninfected control group, infection group 1, and infection group 2. The infection group 1 and infection group 2 were infected with 20 and 40 third-stage(More)
BACKGROUND In our previous studies, it was evident that the dichloromethane-methanol (1:1 v/v) stem barks extract of Polyscias fulva and fractions (ethyl acetate, n-butanol and residue) demonstrated interesting antidermatophytic activities. So, as a continuity of that, this work aimed at identifying active principles with antifungal properties from P. fulva(More)
The vascular effect and immunity effect of SPEF on Wistar mice were studied, and the possible treatment mechanisms and clinical trial methods of SPEF were discussed. We tested lymphocyte proliferation ratio and activity of NK cell, and the contents of IFN-alpha and IL-4 in the serum lymphocyte were inspected with ELISA method. Moreover, macrophage were(More)
A new thermal system for tumor treatment was designed to enhance the curative effects while minimizing invasion to the surrounding healthy tissue. This system includes LN<inf>2</inf>cryosurgery and RF ablation, which can be used separately or simultaneously. A heat transfer model describing the thermal field during treatments was established. The SAR(More)
Traditional Chinese medicines (TCMs) are generally considered complementary or alternative remedies in most Western countries. The constituents of TCMs are hard to define, and their efficacy is difficult to appraise. Thus, the development of suitable methods for evaluating the relationship between bioactivity and the chemical makeup of complex TCM mixtures(More)
Although chromatographic fingerprinting combined with chemometrics, is a rational method for the quality control of traditional Chinese medicine (TCM), chemometrics cannot fully explore the relationship between chemical information and the efficacy of the potential activity. In the present work, a cell-based β₂ adrenergic receptor (β₂AR) agonist functional(More)
Early biomarker-based diagnosis of focal cortical dysplasia (FCD) represents a major clinical challenge. The aim of this study was to identify novel brain microRNAs (miRNAs) in patients with refractory epilepsy and FCD as potential biomarkers. We evaluated serum hsa-miR-4521 as a promising novel biomarker in patients with FCD. Tissue for microarray was(More)
A new guaiane-type diterpenoid, (1alpha,5beta,7alpha)-3,10(18),11-dictytriene-19-acid, was obtained from the roots of Euphorbia wallichii. This is the first isolation of guaiane diterpene from this genus of Euphorbia. The structure was elucidated by spectral methods. And the compound was tested for the cytotoxicities on the cancer cell line P-388 and A-549(More)
With the economy and transport development, License Plate Recognition (LPR) System is a very important direction of Intelligent Transportation Systems (ITS). In this paper, we designed and realized a real time Embedded LPR System based on Digital Signal Processor (DSP). In our system, we fully use arithmetic capability and the rich peripheral interfaces of(More)
