采用白藜芦醇(Res)和富勒烯(C60)结合制备Res/C60纳米组装体并验证其安全性和抗炎性。通过扫描电子显微镜(SEM)、拉曼光谱和X射线衍射研究了纳米组装体形貌、粒径大小及波谱峰值特征。其次,通过紫外分光光度法研究了Res的药物缓释行为。最后,通过MTT法在人脐静脉内皮细胞(HUVECs)层面验证了Res/C60纳米组装体的安全性以及体外的抗炎性。研究发现,Res/C60纳米组装体呈短棒状,横截面平均直径为(379.74±33.47)nm。拉曼光谱和X射线衍射特征峰显示Res/C60纳米组装体被成功制备。Res/C60纳米组装体的聚氨酯(PU)涂层中Res药物在30 d内累积释放量可达60%左右。胆管支架涂层对HUVECs细胞毒性较低,且通过释放Res可显著抑制炎症因子的释放。 相似文献

Students with disabilities often struggle with writing tasks. In order to improve the written expression performance of high school students with deficits in written expression, a Direct Instruction writing program was implemented. The participants were six high school students in programs for individuals with learning disabilities. Three of the six students were served in programs for students who are English Language Learners. Using a multiple‐probe across‐participants design, the effect of the writing program was examined. The intervention was implemented over a 5‐week period with maintenance checks conducted 2 and 4 weeks after the termination of instruction. Results were variable, but there appeared to be a positive trend in student writing performance as measured by correct word sequence, length of text, and the TOWL‐3. Implications for practice and future directions are also provided. 相似文献

This is a pilot study on the readjustment problems of Brazilians returned from graduate study in the United States. Subjects were 31 former LASPAU scholars who were interviewed by the senior author after they were back in Brazil. The family and professional problems they experienced as they tried to readjust to life in their country were investigated, as well as the intensity of these problems and the adequacy of coping, as perceived by the respondent. Taped interviews were coded independently twice, over a 16-month interval. High reliability levels were obtained. Results indicated that returnees had little difficulty adjusting to life with their families except for experiencing some value conflict with them and some lack of privacy. Most of their problems were related to their professional life. In that category they reported that they found some difficulty adjusting to the system as a whole and to their role as professors. Lack of intellectual stimulation, lack of facilities and materials, excessive red tape, lack of opportunity and time to do research was fairly common for most, and they felt these were moderately serious problems. In most cases returnees felt they were coping adequately. 相似文献
