2016年,我曾预言茶叶工业最大流行趋势将是'产品信息透明化'。2017年末,我又撰写了一篇关于茶叶工业可持续发展能力的文章,并预测'可持续'将是今年茶叶工业的发展大趋势。对于透明化和可持续发展的追求,不断推动直接贸易发展壮大,到2017年底,几乎所有新晋茶叶企业均打出了“直接贸易”名号。

世界上的河流管理需要一个整体的、生态系统的观点,不仅仅局部地集中于河岸带,而且还涉及渔业管理和河流的外在因素。河岸带作为河流与流域之间的缓冲带的重要意义由丹麦和荷兰的实例所证明,那里(流域)的农业利用威胁着地表水的质量。另外,来自牙买加、津布巴韦和美国的实例证明了河流的生态价值,同时也阐明了历史上河流的错误管理,并用瑞典农业土地的例子探讨了作为养分过滤器的河岸带的经济价值。整体研究的重要意义由西非河盲疾病所证明,那里疾病威胁着河岸带和在世界范围内引进的外生鱼种。

本文从制度的视角构建一个政府支持公私合营模式(Public Private Partnership,PPP)程度的指数——PPP政府支持指数(PPP Governmental Support Index,GSI)——以评估政府规定的制度体系对在交通基础设施和其他行业引入和推广PPP具有何种程度的促进或阻碍作用。首先,基于大量文献综述界定PPP政府支持指数的要素,包括关于PPP的政策和政治承诺、法律和监管框架,以及精心设计的PPP支持安排。其次,计算20个欧洲国家的PPP政府支持指数,将其分类并比较各国政府对基础设施领域PPP支持程度的异同。再次,探讨20个欧洲国家的制度指数得分与基础设施领域PPP行为的潜在联系。最后,讨论当前的PPP政府支持指数的潜力、实用性以及方法局限性,并详细阐述如何将该指数用于加强交通或其他领域PPP的比较研究中。

Objective: To study coronary artery bypass grafting (CABG) as a risk factor for dementia and Alzheimer disease (Ad) using a case-control design. Methods: The authors used the records-linkage system of the Rochester Epidemiology Project to ascertain incident cases of dementia in Rochester, MN, for the 5-year period 1990 to 1994. The authors defined dementia and Ad using the criteria of the diagnostic and Statistical Manual of Mental disorders, fourth edition (dSM-IV). Each case was individually matched by age (±1 year) and sex to a person drawn randomly from the same population, and free of dementia in the index year (year of onset of dementia in the matched case). Results: Among 557 dementia cases, 24 (4.3%) had undergone a CABG prior to the onset of dementia with a median lag time of 5.5 years (range = 0.1 to 15.9). Among 557 controls, 28 subjects (5.0%) had undergone a CABG prior to the index year with a median lag time 3.9 years (rang e = 0.1 to 12.3); OR = 0.85 (95%CI = 0.49 to 1.49; p = 0.57) for dementia and O R = 0.78 (95%CI = 0.39 to 1.56; p = 0.48) for Ad. The findings did not change a fter adjustment for education. The perioperative courses of cases and controls w ere comparable. Analyses including only the 481 cases of dementia with presumed neurodegenerative or cerebrovascular etiology were also negative. Conclusions: T his population-based case-control study suggests that coronary artery bypass g rafting is not a major risk factor for dementia overall, or for Alzheimer diseas e.

Here we present a docking model that ranks compounds according to their potential effectiveness as a potential substrate or inhibitor. We utilize xanthine oxidase (XO), a multi-cofactor oxido-reductase which converts hypoxanthine to xanthine and xanthine to uric acid. during the reductive half reaction, electrons flow from the molybdopterin, to each of two Fe/S centers, and finally to FAd. during the oxidative half reaction, electrons are passed from the FAd to O2. Under ideal physiological conditions, this reduction of oxygen generates H2O2 and, under multiple turnover conditions, superoxide in amounts which is regulated by catalase and superoxide dismutase. Utilizing computer modeling predictions of the docking orientations and energies of a group of purine based structures was selected. Correlating computer estimations with steady state kinetic data, a rapid screening process for inhibittor prediction was highlighted. This method allows educated selection of likely inhibitors, thereby decreasing the time and supplies required to complete a traditional kinetic analysis screening. Results demonstrate the functionality and reliability of this method and have proven particularly useful in understanding binding orienttations or poses of each compound.
