Dear Editor,Protein import into chloroplasts is an essential process for plant survival. Numerous studies in recent years have revealed many facts about the components involved and mechanistic features, but have also turned up some controversies. Especially the composition and function of the Tic （translocon at the inner enve- lope of chloroplasts） complex（es） are vividly debated. Whereas the importance of one central Tic component,

本研究旨在调查法国和中国消费者的购买决策。研究重点是两个方面,一方面是天然化妆品,另一方面是这些产品的起源国。如今,越来越多的消费者对其化妆品的质量是敏感的。越来越多的公共卫生问题导致消费者更多地考虑他们正在购买什么以及他们在皮肤上的含量。消费者更倾向于购买天然化妆品,而不是购买含有源自石油化学品的物质的传统化妆品。为了回应消费者的不断变化的行为,制造公司特别重视开发包含有较少化学物质和更多的自然元素的化妆品。增加公众健康关注使消费者更多地考虑他们正在购买什么以及他们把什么物质放在皮肤上。代替购买含有源自石化产品的传统化妆品,消费者更倾向于购买天然化妆品。这项研究特别考察了一个具体因素,这是这些天然化妆品的起源国。原产国的重要性在消费者的购买决定中起着重要作用,但这一重要性尚待确定。法国消费者被选中是因为法国天然化妆品市场不断增长。如今,法国天然化妆品品牌在全球知名,在全球天然化妆品市场享有很高的声誉。此外,法国天然化妆品市场是发达的,并且强烈地存在于法国消费者的心中。中国消费者也因为中国化妆品市场不断上涨而得到分析。越来越多的品牌正在推出自已的天然化妆品,以吸引客户。这项研究的目的是阐明法国和中国消费者购买行为和原产地国家的形象之间的关系。研究工作强调了天然化妆品生产国的重要性,与其他四个主要标准相比。然后本文旨在比较影响法国和中国消费者购买决策的因素。为了测试该假设,在法国和中国消费者中进行了问卷调查。抽样调查人员来自居住在法国和中国的男性和女性客户。调查问卷包含了首先评估天然化妆品原产国重要性的答案,与其他四项主要标准进行比较,其次是比较法国和中国消费者眼中起源国的重要性。研究的结果在研究的第四部分进行了描述,其中分析了获得的数据并支持或拒绝了假设。

Background It is debatable whether treating multimorbid nursing home patients with antihypertensive drugs produces beneficial effects. Most cardiovascular guidelines promote treatment; few have advice on how to deprescribe when treatment may no longer be necessary. We investigated the effect of medication review on antihypertensive drug use and the association between cognition, blood pressure, and prescribing. Methods From August 2014 to December 2015, 765 patients from 72 units （clusters） in 32 Norwegian nursing homes were included in a 4-month, multicentre, cluster-randomized, controlled trial, with 9-month follow-up. Patients ≥ 65 years old with antihypertensive treatment （n = 295, 39%） were randomized to systematic medication review where the physician received support from peers （collegial mentoring） or were given care as usual （control condition）. Outcome measures were the number of antihypertensive drugs, systolic blood pressure, and pulse. We used hospitalizations and deaths as criteria to assess harm. Results At baseline, each patient used 9.2 ± 3.5 regular drugs, and 1.6 ± 0.7 antihypertensives. Mean blood pressure was 128/71 mmHg and 9% had a systolic pressure ≥ 160 mmHg. Between baseline and month four, antihypertensives were deprescribed to a significantly higher extent in the intervention group （n = 43, 32%） compared to control （n = 11, 10%）; Incidence Rate Ratio = 0.8, 95% CI = 0.7？0.9. In the intervention group, there was an immediate increase in systolic blood pressure when antihypertensives were reduced, from baseline 128 ± 19.5 mmHg to 143 ± 25.5 mmHg at month four. However, at month nine, the blood pressure had reverted to baseline values （mean 134 mmHg）. Deprescription did not affect pulse and systolic pressure. The number of hospitalizations was higher in control patients at month four （P = 0.031） and nine （P = 0.041）. Conclusion A systematic medication review supported by collegial mentoring significantly decreased the use of antihypertensive

Ni/SiO2-ZrO2 catalysts with Ni loadings of 1 to 13 wt-% were prepared, characterized by elemental analysis, X-ray diffraction, N2 sorption, temperature programmed oxidation, temperature programmed reduc- tion, and tested for their activity and stability in the dry reforming of methane with carbon dioxide at 850 ℃, gas hourly space velocity of 6000 and 1800 h^-1 and atmo- spheric pressure. The SiO2-ZrO2 support as obtained through a simple and efficient sol-gel synthesis is highly porous （ABET = 90 m^·g^-1, dp= 4.4 nm） with a homogeneously distributed Si-content of 3 wt-%. No loss of Si or formation ofmonoclinic ZrO2, even after steaming at 850 ℃ for 160 h, was detectable. The catalyst with 5 wt-% Ni loading in its fully reduced state is stable over 15 h on-stream in the dry reforming reaction. If the catalyst was not fully reduced, a reduction during the early stages of dry reforming is accompanied by the deposition of up to 44 mg· g^-1 carbon as shown by experiments in a magnetic suspension balance. Rapid coking occurs for increased residence times and times-on-stream starting at 50 h. The Ni loading of 5 wt-% on SiO2-ZrO2 was shown to provide an optimal balance between activity and coking tendency.
