Aim of the study
Rheumatoid arthritis synovial fibroblasts (RASFs) are known to produce matrix metalloproteinases (MMPs) and cause joint destruction. The purpose of this study is to develop a potential medicine for rheumatoid arthritis (RA).Materials and methods
To this end, first, the MMPs inhibition factor was purified from an alkali-solubilized fraction of RJ (Apis mellifera) by C18 reverse-phase column chromatography and identified as 10-hydroxy-2-decenoic acid (10H2DA) by LTQ XL analysis. Next, Experimental test 10H2DA how to inhibited the activities of MMPs: with RASFs isolated from rheumatoid tissues by enzymatic digestion, cultures in monolayers were treated with 10H2DA (0.5 mM, 1 mM, and 2 mM) or PBS for 2 h followed by stimulation with TNF-α (10 ng/ml) for 2 h, mRNA. Protein levels of MMP-1 and MMP-3 were measured by real-time PCR and enzyme-linked immunosorbent assay (ELISA), the DNA-binding activity of activator protein-1 (AP-1) and nuclear factor κB (NF-κB) by electrophoretic mobility shift assay (EMSA), and the protein kinase activity of p38, ERK and JNK by kinase assay.Results
The molecular investigation revealed that the 10H2DA-mediated suppression was likely to occur through blocking p38 kinase and c-Jun N-terminal kinase–AP-1 signaling pathways. In contrast, 10H2DA had no effect on extracellular signal-regulated kinase activity, NF-κB DNA-binding activity and IκBα degradation.Conclusion
These results suggest that 10H2DA may be of potential therapeutic value in inhibiting joint destruction in RA. 相似文献62.
自然语言中数字的语义模糊性表达及其特殊的修辞功能无处不在。翻译不是字当句对,而是保留语言的总风格和力量,按分量而不是数量译词。模糊数字的翻译不能拘泥于数字本身的数值,而必须依托具体语境,悉心推敲原文的修辞特色,着重从文采上考虑,精心选择适当词语译出意境。 相似文献

OBJECTIVE: The deficit in transplantable organs is making it necessary to find alternative sources. One possibility is xenotransplantation. However, the use of animal organs may be rejected by society and among health professionals. Primary Care is fundamental for promoting matters of health; in Spain it has access to nearly 100% of the population. Our objective was to analyze the acceptance of this therapy, although it is experimental, among Primary Care professionals, given that they are the ones most involved in spreading information about this therapy if it was confirmed to be useful. MATERIALS AND METHODS: A random sample was stratified by sex, job category, and geographical location among Primary Care personnel, including 428 professionals in 32 health centers among population of 2851 professionals. Attitudes toward xenotransplantation were evaluated using a questionnaire on psychosocial attitudes validated in our geographical area. Contact was made in each center with the Doctor Coordinator for doctors, the Nursing Coordinator for nurses, and an Administrative Officer for ancillary personnel. The chi-square test and Student t test were applied to evaluate categorical and continuous data, respectively. RESULTS: Attitudes toward xenotransplantation were similar to those obtained in human organs: favorable in 79% (n = 325), whereas 19% (n = 78) had doubts and 2% (n = 10) were against. The attitude was more favorable in men (89% vs 72%; P < .000), those who had cared for transplant patients (84% vs 71%; P = .009), those with previous experience in organ donation and transplantation (84% vs 75%; P = .033), those with an attitude in favor of cadaveric organ donation (83% vs 66%; P < .0001), and those in favor of living donation of the kidney (P < .000) or the liver (P < .000), as well as those who believed that they may need a transplant at some time in the future (84% vs 74%; P = .045). There was a clear difference in attitude according to job category (P = .018): approval rates were 89% for doctors, 76% for nurses, and 70% for ancillary personnel. CONCLUSIONS: Attitudes toward future application of xenotransplantation were quite positive among doctors. However, the attitudes of nursing and ancillary personnel were similar to those of the general population. The main factors related to such an attitude depended mainly on the previous relationship and attitude of the respondent toward human organ donation and transplantation. 相似文献

—We report the case of a 37-year-old woman who had a characteristic hair with dark bands of normal hair and bright thicker bands with slight cuticular changes. There was no known family history.X-ray microanalysis demonstrated a sulphur decrease in the bright bands with respect to the dark ones. We considerer this case either sporadic or with a mild genetic penetrance. Clinical, morphological and ultrastructural findings were minimal. 相似文献

皮尔斯把类象符号分为意象象似性、拟象象似性和隐喻象似性三种,这个分类与Lakoff &Johnson的概念隐喻理论结合起来可以很好地揭示隐喻手势的表征方式。皮尔斯符号“三位一体”的整体性使符号成为真正的“说明项”,在具体语境中具备元话语功能。通过分析,口语诗《广岛》中的隐喻手势具备突出对照、否定评价和谋篇布局的元话语功能。本研究不仅揭示了言语隐喻中无法体现的思维层面的内容,而且有助于对口语交际中隐喻手势的理解。 相似文献
