Stripe (yellow) rust, caused by Puccinia striiformis f. sp. tritici (Pst), is one of the most devastating wheat diseases worldwide. Triticum aestivum-Haynaldia villosa 6VS/6AL translocation lines carrying the Yr26 gene on chromosome 1B, are resistant to most races of Pst used in virulence tests. In order to better utilize Yr26 for wheat improvement, we(More)
Nineteen common wheat cultivars and advanced lines carrying a 6VS.6AL translocation and five parents were sown at two locations in Jiangsu in 2004–05 season to assess the effects of the translocation on grain yield and dough properties. In general, there were no significant differences between 6VS.6AL lines and their recurrent parents in agronomic,(More)
BACKGROUND Human cord blood (CB) is a superior source of regulatory T cells (Tregs) compared with peripheral blood. Initial studies have shown that CB-derived Tregs can be effectively expanded ex vivo. However, in vitro suppressor activity of expanded CB-Tregs and their efficacy in the prevention of acute graft-versus-host disease (aGVHD) in vivo are poorly(More)
OBJECTIVE To probe the significance of specific IgG4 in sera of patients with cerebral cysticercosis for diagnosis and therapeutic evaluation. METHODS Specific IgG4 in sera of patients with cerebral cysticercosis was assessed using colloidal gold-labeled mouse-anti-human IgG4 McAb as probe. The results were compared with the CT image manifestation. (More)
In this study, we expanded regulatory T cells (Tregs) ex vivo from CD4(+) CD25(+) T cells from cord blood (CB) and CD4(+) CD25(+) CD127(-) T cells from adult peripheral blood (APB) and compared the suppressive functions of the newly generated Tregs. The Tregs from CB and APB were expanded either in two cycles with a polyclonal stimulus or in two cycles with(More)
Phosphoenolpyruvate carboxykinase (PEPCK) catalyzes guanosine or adenosine mononucleotide-dependent reversible conversion of oxaloacetate (OAA) and phosphoenolpyruvate (PEP). Mycobacterium (M) tuberculosis possesses a putative GTP-dependent PEPCK. To analyze the immune responses caused by PEPCK, the effects of PEPCK on the induction of CD4+ T cells and(More)
AIM To analyze the biological role of the surface antigen of Toxoplasma gondii (T gondii) in development of vaccine. METHODS The surface antigen of T gondii (SAG1) was expressed in vitro. The immune response of the host to the antigen was investigated by detection of specific antibody reaction to SAG1 and production of cytokines. Mice were immunized with(More)
The therapeutic efficacy of radioimmunotherapy (RIT) of 188Re-labeled herceptin, which is a humanized anti-p185-HER2/neu monoclonal antibody (mAb), was studied. The nude mice bearing nasopharyngeal carcinoma (NPC) expressing HER2/neu protooncogene were injected with 188Re-herceptin intratumorally and intravenously. The biodistribution was observed on day 2(More)
AIM To evaluate the multi-step pretargeting radioimmunoimaging (RII) and radioimmunotherapy (RIT) in nude mice bearing human colon carcinoma with avidin-biotin system labeled with (153)Sm. METHODS Two- and three-step strategies for avidin-biotin system pretargeting techniques were established. In a three-step procedure, human colon carcinoma bearing nude(More)
OBJECTIVE To investigate the morbidities of low vision and blindness and the leading cause of blindness in residents aged >or= 60 years in Beixinjing blocks, Shanghai. METHODS The vision archives were first established for total old residents. The pinhole visual acuity was recorded and classified under WHO grading system. Assigned ophthalmologic doctors(More)
