Induction of tumor cell apoptosis has been recognized as a valid anticancer strategy. However, therapeutic selectivity between tumor and normal cells has always been a challenge. Here, we report a novel anti-cancer compound methyl 3-(4-nitrophenyl) propiolate (NPP) preferentially induces apoptosis in tumor cells through P450-catalyzed reactive oxygen(More)
Constitutive activation of the Janus kinase (JAK)/signal transducer and activator of transcription (STAT) pathway occurs frequently in cancer cells and contributes to oncogenesis. Among the members of STAT family, STAT3 plays a pivotal role in the development and progression of human tumors. The STAT3-mediated signaling pathway has been recognized as a(More)
Trichinella spiralis paramyosin (Ts-Pmy) is a protective antigen that induces partial immunity against T. spiralis infection in mice. To identify protective epitope of Ts-Pmy, a monoclonal antibody (mAb) 7E2 against the recombinant protein was generated, which partially protected against T. spiralis infection following passive transfer. The mAb was used to(More)
A cDNA encoding heat shock protein 70 of Trichinella spiralis (Ts-Hsp70) was identified by immunoscreening the adult T. spiralis cDNA library with rabbit antisera against T. spiralis adult extracts. The open reading frame of Ts-Hsp70 cDNA encoded a 623-amino acid peptide with a predicted molecular weight of 68.7kDa, which shares a high degree of sequence(More)
A full-length cDNA encoding Trichinella spiralis paramyosin (Ts-Pmy) was cloned by immunoscreening a cDNA library of the adult T. spiralis worm. Ts-Pmy cDNA consists of 2655bp that encode 885 amino acids. The recombinant protein (rTs-Pmy) was expressed and purified by Ni-affinity chromatography. Western blot analysis showed that rTs-Pmy could be recognized(More)
Our previous studies showed that immunization with recombinant paramyosin from Trichinella spiralis (rTs-Pmy) formulated with Freund's adjuvant significantly reduced larval burden in mice after T. spiralis larval challenge. Since Freund's adjuvant is toxic and not a suitable adjuvant for clinical vaccine trials, we evaluated the ability of the adjuvants(More)
Although the task of data record extraction from Web pages has been studied extensively, yet it fails to handle many pages due to their complexity in format or layout. In this paper, we propose a unified method to tackle this task by addressing several key issues in a uniform manner. A new search structure, named as Record Segmentation Tree (RST), is(More)
Selectively eradicating cancer cells with minimum adverse effects on normal cells is a major challenge in the development of anticancer therapy. We hypothesize that nutrient-limiting conditions frequently encountered by cancer cells in poorly vascularized solid tumors might provide an opportunity for developing selective therapy. In this study, we(More)
Trichinellosis is a global zoonosis mainly caused by Trichinella spiralis. We have previously reported that a novel Ts87 gene from the cDNA library of adult T. spiralis was cloned and expressed in a prokaryotic expression system. Vaccination with recombinant Ts87 protein (rTs87) induced a muscle larvae burden reduction in BALB/c mice by 29% in response to(More)
In this study, a simple and sensitive LC/MS/MS method was developed and validated for the determination of arctigenin in rat plasma. The MS detection was performed using multiple reaction monitoring at the transitions of m/z 373.2 → 137.3 for arctigenin and m/z 187.1 → 131.0 for psoralen (internal standard) with a Turbo IonSpray electrospray in positive(More)
