Résumé L'action adrénocorticotrope d'un polypeptide à 25 acides aminés, comprenant 3 modifications de structure par rapport à la séquence 1–25 de l'ACTH naturelle est étudiée et démontrée. La destruction enzymatique de ce pentacosapeptide paraît être plus lente dans le sang que dans les tissus musculaire et sous-cutané. L'augmentation de la dose injectée produit un allongement de la durée de stimulation de la cortico-surrénale.  相似文献

In this article we discuss how an interdisciplinary research team partnered with a variety of stakeholders concerned with and/or affected by the impacts of climate change in the Red River Delta of Vietnam. The research, undertaken from 2016 to 2018, drew upon a wide range of methods to investigate systemically these impacts – with a view to the research inputting into the development of (more) sustainable ways of living. The research solicited various accounts of the experience of climate change in the community, set up learning processes in community meetings, and created an interface with government officials positioned at commune, district, provincial, and national levels. The intention was to offer support towards developing a learning process (broadly defined as including learnings/systemic inquiry across organizational levels of the society) to pursue options for sustainable living. The article offers our post-facto reflections which render more explicit (to ourselves and for the benefit of audiences) how the research team, with Hoang as lead researcher, facilitated the inquiry process towards developing a synthesis which underscored the assets for resilience to climate change and supported interventions to strengthen such (defined) assets.

As the avian influenza virus H5N1 swept from Asia across Russia to Europe, Nigeria was the first country in Africa to report the emergence of this highly pathogenic virus. Here we analyse H5N1 sequences in poultry from two different farms in Lagos state and find that three H5N1 lineages were independently introduced through routes that coincide with the flight paths of migratory birds, although independent trade imports cannot be excluded.  相似文献

Organic light-emitting diodes (OLEDs) represent a promising technology for large, flexible, lightweight, flat-panel displays. Such devices consist of one or several semiconducting organic layer(s) sandwiched between two electrodes. When an electric field is applied, electrons are injected by the cathode into the lowest unoccupied molecular orbital of the adjacent molecules (simultaneously, holes are injected by the anode into the highest occupied molecular orbital). The two types of carriers migrate towards each other and a fraction of them recombine to form excitons, some of which decay radiatively to the ground state by spontaneous emission. Doped pi-conjugated polymer layers improve the injection of holes in OLED devices; this is thought to result from the more favourable work function of these injection layers compared with the more commonly used layer material (indium tin oxide). Here we demonstrate that by increasing the doping level of such polymers, the barrier to hole injection can be continuously reduced. The use of combinatorial devices allows us to quickly screen for the optimum doping level. We apply this concept in OLED devices with hole-limited electroluminescence (such as polyfluorene-based systems), finding that it is possible to significantly reduce the operating voltage while improving the light output and efficiency.  相似文献

本文将针灸穴名意译成英、德、法三种外文、列表。在翻译过程中发现所发表的第一部分尚有不少不当或错误之处,在翻译具体名词时修正。经络名称采用中国针灸学会所建议的拉丁译名;保留了英德所用的编号;提供了缩写。为了译名在不同的语种中有共同或类似的拼音以便通用并对其缩写较易记忆与运用,有些英译未用最常见的词,有的语种少数词意略有差别(但仍相关),有些则用医学常见的拉丁代替。文中阐述了一些穴名翻译中存在的特殊问题以助了解。热忱欢迎批评指教。  相似文献
