Coenurosis is an important zoonotic helminthic disease caused by the larval stage of the tapeworm Taenia multiceps. This parasite typically infects the brain of the intermediate hosts, including sheep, goat, cattle and even humans. We report a case of T.

Nonetheless, due to lack of multiple insertion sites in these plant viruses, it is still a big challenge to simultaneously express multiple foreign proteins in single cells. The genome of Beet necrotic yellow vein virus (BNYVV) offers an attractive system for expression of multiple foreign proteins owning to a multipartite genome composed of five positive-stranded RNAs.

The response mechanism to the Bacillus amyloliquefaciens volatiles in plant has not been well studied. We conducted global gene expression profiling in Arabidopsis after treatment with Bacillus amyloliquefaciens FZB42 volatiles by Illumina Digital Gene Expression (DGE) profiling of different growth stages (seedling and mature) and tissues (leaves and roots).

This study was designed to observe the role of FOS protein expression in the rat medullary visceral zone (MVZ) in multiple organ dysfunction syndrome (MODS) caused by subarachnoid hemorrhage (SAH), with and without severing the vagus nerve. We also investigated the regulatory and control mechanisms of the MVZ and the vagus nerve in MODS following SAH. A model of MODS following SAH was established by injecting arterial blood into the Willis' circle.

Perturbation of redox homeostasis coupled with the generation of reactive oxygen species (ROS) ensues.

Objective: To survey the prevalence of drug resistant HIV in Zhejiang province in 2009-2011.
Methods: WHO truncated sequential sampling technique was adopted annually by using 63, 62 and 57 samples of newly diagnosed as HIV positive and aged 16-25 years in Hangzhou, Ningbo and Wenzhou from 2009 to 2011, respectively. RNA was prepared and HIV pol region was amplified by RT-PCR and nested PCR.

Objective: To analyze the relationship between strain subtypes and transmission of HIV infection on marriage-based immigrant women, their spouses and children in rural area of Zhejiang province.
Methods: Marriage-based immigrant women with HIV infection, their HIV infected spouses and children in rural area in Zhejiang province, were selected as study objects. Analysis on genetic sequence and epidemiologic information was carried out.
Artemisinins rapidly oxidize leucomethylene blue (LMB) to methylene blue (MB); they also oxidize dihydroflavins such as the reduced conjugates RFH₂ of riboflavin (RF), and FADH₂ of the cofactor flavin adenine dinucleotide (FAD), to the corresponding flavins. Like the artemisinins, MB oxidizes FADH₂, but unlike artemisinins, it also oxidizes NAD(P)H. Like MB, artemisinins are implicated in the perturbation of redox balance in the malaria parasite by interfering with parasite flavoenzyme disulfide reductases.

Objective: To study the genotypic drug-resistant mutation among treat-naïve or treated patients infected with HIV-1 CRF01_AE in Zhejiang province during 2004-2007.
Methods: HIV-1 pol amplicons (PR + RT) from 13 treated and 43 treat-naïve patients were obtained by reverse transcription-polymerase chain reaction (RT-PCR). The sequences were analyzed for genotypic antiretroviral resistance through online tools (http://hivdb.
Nasopharyngeal carcinoma is a neoplasm with a high incidence in Southeast Asia, and it is strongly associated with Epstein-Barr virus (EBV) activation involving the expression of a weakly immunogenic protein, namely, latent membrane protein (LMP)-2. Previous immunological studies already identified the human leukocyte antigen (HLA)-A11 restricted peptide epitope (SSCSSCPLSK) in the LMP-2 antigen. In this work, we prepared gold nanoparticle (AuNP)-peptide conjugate 1 by treating the nanoparticles with the N-cysteinated LMP-2 epitope.

HCA661 is a cancer-testis (CT) antigen frequently expressed in human hepatocellular carcinoma (HCC). To search for immunogenic peptides of HCA661, bioinformatics analysis and CD8(+) T cell IFN-gamma ELISPOT assay were employed, and two HLA-A *0201 restricted peptides, H110 and H246, were identified. These two HCA661 peptides are naturally processed in dendritic cells (DCs) and when used for DCs loading, they are sufficient to prime autologous CD8(+) T cells to elicit cytotoxic response against HCA661(+) human cancer cells.

We employed online database analysis to compare the differences in the amino acid sequences of the homologous T epitopes of HCoV-229e and SARS-CoV. The identified T-cell epitope peptides were synthesized, and their binding affinities for HLA-A2 were validated and compared in the T2 cell system.
