| 1 | Nat Biotechnol:将人星形胶质细胞重编程为多巴胺能神经元,有助治疗帕金森病显示文摘帕金森病是一种主要影响运动系统的神经退行性疾病。它的特征在于大脑中的多巴胺能神经元(dopaminergic neuron)渐进性丧失。尽管当前的疗法旨在补充多巴胺水平,但是没有一种疗法能够恢复这些丢失的细胞。如今。在一项新的研究中,来自瑞典、奥地利、西班牙和美国的研究人员开发出一种方法:将神经胶质细胞(glialcell)转化为活性的多巴胺能神经元,并且所产生的多巴胺能神经元能够部分恢复帕金森病模式小鼠的运动功能。这项概念验证研究可能为开发出一种治疗这种疾病的新方法铺平道路。 | Pia Rivetti di Val Cervo, Elisa Martín-Montañez, Enrique M Toledo, Gioele La Manno, Sara Padrell Sánchez, Sten Linnarsson Ernest Arenas Roman A Romanov, Christian Pifl Tibor Harkany Roman A Romanov, Giada Spigolon, Débora Masini, Michael Feyder, Tibor Harkany Gilberto Fisone Elisa Martín-Montañez Yi-Han Ng Marius Wernig | 2017 | 现代生物医学进展2017,17,17: | 11 |
| 2 | Attenuation of dextran sodium sulphate induced colitis in matrix metalloproteinase-9 deficient mice显示文摘AIM: To study whether matrix metalloproteinase-9 (MMP-9) is a key factor in epithelial damage in the dextran sodium sulphate (DSS) model of colitis in mice.METHODS: MMP-9-deficient and wild-type (wt) mice were given 5% DSS in drinking water for 5 d followed by recovery up to 7 d. On d 5 and 12 after induction of colitis, gelatinases, MMP-2 and MMP-9, were measured in homogenates of colonic tissue by zymography and Western blot, whereas tissue inhibitor of metalloproteinases (TIMPs) were measured by reverse zymography. The gelatinolytic activity was also determined in supernatants of polymorphonuclear leukocytes (PMN) isolated from mice blood. Moreover, intestinal epithelial cells were stimulated with TNF-α to study whether these cells were able to produce MMPs. Finally, colonic mucosal lesions were measured by microscopic examination. RESULTS: On d 5 of colitis, the activity of MMP-9 was increased in homogenates of colonic tissues (0.24 ± 0.1 vs 21.3 ± 6.4, P < 0.05) and PMN from peripheral blood in wt (0.5 ± 0.1 vs 10.4 ± 0.7, P < 0.05), but not in MMP-9-deficient animals. The MMP-9 activity was also up-regulated by TNF-α in epithelial intestinal cells (2.5 ± 0.5 vs 14.7 ± 3.0, P < 0.05). Although colitis also led to increase of TIMP-1 activity, the MMP-9/TIMP-1 balance remained elevated. Finally, in the MMP-9-deficient colitic mice both the extent and severity of intestinal epithelialinjury were significantly attenuated when compared with wt mice. CONCLUSION: We conclude that DSS induced colitis is markedly attenuated in animals lacking MMP-9. This suggests that intestinal injury induced by DSS is modu-lated by MMP-9 and that inhibition of this gelatinase may reduce inflammation. | Alfredo Santana Carlos Medina Maria Cristina Paz-Cabrera Federico Díaz-Gonzalez Esther Farré Antonio Salas Marek W Radomski Enrique Quintero | 2006 | World Journal of Gastroenterology2006,12,40: | 9 |
| 3 | Endoscopic submucosal dissection training with pig models in a Western country显示文摘AIM:To test a strategy for endoscopic submucosal dissection(ESD) training in animal models designed to overcome the initial learning curve.METHODS:ESD was attempted in ex vivo and in vivo pig models.Thirty ESD procedures were attempted in the esophagus(n=9) or the stomach(n=21).The ex vivo model was used until initial competence was achieved.In the in vivo model,several ESD procedures were performed in up to 3 sessions.The following variables were analyzed:specimen size,complete and en bloc resection rate,time for circumferential incision,time for submucosal dissection,total ESD duration,and complications.RESULTS:Complete resection was achieved in 28 cases(en bloc 27);2 could not be completed(one perforation,one technical diff iculty).The mean ± SD time for circumferential incision was 36.2±16.8 min(range:8-87 min),and the mean±SD time for submucosal dissection was 45.1±35.7 min(range:9-196 min).The mean±SD size of the resected specimens was 45.2±17.8 mm.The mean±SD total resection time was signif icantly increased for the gastric cases performed in the f irst half of the study(n=13) than in the second half(n=8)(98.9±62.4 min vs 61.7±17.6 min,P=0.04),although the specimen size did not differ.CONCLUSION:Training in animal models could help endoscopists overcome the learning curve before starting ESD in humans. | Adolfo Parra-Blanco María Rosa Arnau David Nicolás-Pérez Antonio Z Gimeno-García Nicolás González Juan A Díaz-Acosta Alejandro Jiménez Enrique Quintero | 2010 | World Journal of Gastroenterology2010,16,23: | 9 |
| 4 | Therapeutic options for HER-2 positive breast cancer: Perspectives and future directions显示文摘During the last 15 years we have witnessed an unprecedented expansion in the drugs developed to target human epidermal growth factor receptor-2(HER-2) positive breast cancer. Trastuzumab, pertuzumab, adotrastuzumab emtansine and lapatinib are currently food and drug administration(FDA)-approved for the treatment of breast cancer patients with HER-2 overexpressed. However, given the amount of information gathered from years of uninterrupted clinical research, it is essential to have periodic updates that succinctly recapitulate what we have learnt over these last years and help us to apply that information in our daily practice. This review will pursue that objective. We will summarize the most relevant and updated informationrelated to the state of the art management of HER-2 positive breast cancer in all the clinical scenarios including the adjuvant, neoadjuvant and metastatic settings. But we will also critically appraise that literature in order to highlight some key clinical concepts that should not be overlooked. Lastly, this review will also point out some of the most promising strategies that are currently being tested and may soon become available. | Gonzalo Recondo Jr Enrique Dìaz Canton Màximo de la Vega Martin Greco Gonzalo Recondo Sr Matias E Valsecchi | 2014 | World Journal of Clinical Oncology2014,5,3: | 7 |
| 5 | Need for infliximab dose intensification in Crohn's disease and ulcerative colitis显示文摘AIM: To compare the need for infliximab dose intensification in two cohorts of patients with Crohn's disease(CD) or ulcerative colitis(UC).METHODS: Single centre, uncontrolled, observational study. Consecutive patients with CD and UC who responded to infliximab induction doses were included. Data collected in a prospectively maintained database were retrospectively analysed. Differences in the rates of dose intensification per patient-month and the intensification-free survival time were compared. We also evaluated the interval between the first infliximab induction dose and the first infliximab escalated dose. The weight-adjusted infliximab administration costs were also calculated.RESULTS: Fifty nine patients with CD and 38 patients with UC were enrolled. The rate of intensification per patient-month was 3.9% for UC and 1.4% for CD(P = 0.005). The median time from baseline to intensification was significantly shorter in UC compared to CD [6.6 mo(IQR: 4.2-9.5 mo) vs 10.7 mo(IQR: 8.9-11.7 mo), P = 0.005]. In the survival analysis, the cumulative probability of avoiding infliximab dose intensification was significantly higher in CD(P = 0.002). In the multivariate analysis, disease(UC vs CD) was the only factor significantly associated with dose intensification. The infiximab administration costs during the first year were significantly higher for UC compared to CD(mean ± SD 234.9 ± 53.3 Euros/kg vs 212.3 ± 15.1 Euros/kg, P = 0.03).CONCLUSION: The rate of infliximab dose intensification per patient-month is significantly higher in UC patients. The infliximab administration costs are also significantly higher in patients with UC. | Carlos Taxonera David Olivares Juan L Mendoza Manuel Díaz-Rubio Enrique Rey | 2014 | World Journal of Gastroenterology2014,20,27: | 2 |
| 6 | Coronary physiology assessment in the catheterization laboratory显示文摘Physicians cannot rely solely on the angiographic appearance of epicardial coronary artery stenosis when evaluating patients with myocardial ischemia. Instead, sound knowledge of coronary vascular physiology and of the methods currently available for its characterization can improve the diagnostic and prognostic accuracy of invasive assessment of the coronary circulation, and help improve clinical decision-making. In this article we summarize the current methods available for a thorough assessment of coronary physiology. | Felipe Díez-delhoyo Enrique Gutiérrez-Ibanes Gerard Loughlin Ricardo Sanz-Ruiz María Eugenia Vázquez-álvarez Fernando Sarnago-Cebada Rocío Angulo-Llanos Ana Casado-Plasencia Jaime Elízaga Francisco Fernández Avilés Diáz | 2015 | World Journal of Cardiology2015,7,9: | 2 |
| 7 | Advances and new perspectives in the treatment of metastatic colon cancer显示文摘During the last decade we have witnessed an unprec-edented outburst of new treatment approaches for the management of metastatic colon cancer.Anti-angio-genic drugs,epidermal growth factor receptor blockers and multi-kinase inhibitors have all resulted in small but consistent improvement in clinical outcomes.However,this progress has paradoxically leaded us into new chal-lenges.In many cases the clinical development was done in parallel and the lack of head-to-head compari-son evolved into circumstances where several valid new'standards of care'are available.Even though desir-able in essence,the availability of many options as well as different possible combinations frequently leaves the busy clinician in the difficult situation of having to choose between one or the other,sometimes without solid evidence to support each decision.In addition,progress never stops and new agents are continuously tested.For these reason this review will try to summa-rize all the clinical trials that constitute the theoretical framework that support our daily practice but will also procure the reader with rational answers to common clinical dilemmas by critically appraising the current literature.Lastly,we will provide with a compilation of promising new agents that may soon become our next line of defense against this deadly disease. | Gonzalo Recondo Jr Enrique Díaz-Cantón Máximo de la Vega Martin Greco Gonzalo Recondo Sr Matias E Valsecchi | 2014 | World Journal of Gastrointestinal Oncology2014,6,7: | 2 |
