1为今天 为明天 更为千秋万代的教育——可持续发展教育论坛显示文摘发展,可持续发展的前提;人,可持续发展的中心体;可持续发展教育(ESD),是根据可持续发展需要而推行的教育。云南省社科联与瑞典国际项目办公室组织的'中瑞可持续发展教育比较合作研究培训'开启了ESD这一崭新教育理念的创新探索。在云南大学可持续发展教育研究的硕士生课程上,博士生、硕士生以及相关学者各抒己见。张建新 Kerstin Sonesson 廖鸿志 Per Sund 贺新宇 蒋亚兵 李红 Helen Hasslf 曹五军 杨四英 杨黎 张振碧 王晓艳 杨叶 邹源椋 张绵 杜升燕 2012学园(学者的精神家园)2012,,2:6
2Counter-regulatory phosphatases TNAP and NPP1 temporally regulate tooth root cementogenesis显示文摘Cementum is critical for anchoring the insertion of periodontal ligament fibers to the tooth root. Several aspects of cementogenesis remain unclear, including differences between acellular cementum and cellular cementum, and between cementum and bone.Biomineralization is regulated by the ratio of inorganic phosphate(Pi) to mineral inhibitor pyrophosphate(PPi), where local Piand PPi concentrations are controlled by phosphatases including tissue-nonspecific alkaline phosphatase(TNAP) and ectonucleotide pyrophosphatase/phosphodiesterase 1(NPP1). The focus of this study was to define the roles of these phosphatases in cementogenesis. TNAP was associated with earliest cementoblasts near forming acellular and cellular cementum. With loss of TNAP in the Alpl null mouse, acellular cementum was inhibited, while cellular cementum production increased, albeit as hypomineralized cementoid. In contrast, NPP1 was detected in cementoblasts after acellular cementum formation, and at low levels around cellular cementum. Loss of NPP1 in the Enpp1 null mouse increased acellular cementum, with little effect on cellular cementum.Developmental patterns were recapitulated in a mouse model for acellular cementum regeneration, with early TNAP expression and later NPP1 expression. In vitro, cementoblasts expressed Alpl gene/protein early, whereas Enpp1 gene/protein expression was significantly induced only under mineralization conditions. These patterns were confirmed in human teeth, including widespread TNAP, and NPP1 restricted to cementoblasts lining acellular cementum. These studies suggest that early TNAP expression creates a low PPienvironment promoting acellular cementum initiation, while later NPP1 expression increases PPi, restricting acellular cementum apposition. Alterations in PPihave little effect on cellular cementum formation, though matrix mineralization is affected.Laura E Zweifler Mudita K Patel Francisco H Nociti Jr Helen F Wimer Jose L Milln Martha J Somerman Brian L Foster 2015International Journal of Oral Science2015,7,1:5

4卫生政策分析:概念和方法的思考与挑战显示文摘许多专家学者就卫生政策分析开展了大量研究,但很少关注如何进行政策分析以及需要什么样的研究设计、理论和方法。本文着眼于卫生政策分析的环境以及面临的挑战,借鉴中低收入国家中一些卫生政策分析的框架、理论、方法和设计,列举了最近的研究案例,并探讨了案例研究的意义以及研究设计的必要性,发现卫生政策研究者的角色、反思和定位在研究过程中非常重要。最后从理论、方法学和研究人员的反思等角度提出了促进卫生政策分析的建议。Gill Walt Jeremy Shiffman Helen Schneider Susan F Murray Ruairi Brugha Lucy Gilson 2012中国卫生政策研究2012,5,12:3
