Gut microbiota and lipids: impact on human health The human intestine harbours a complex and diverse bacterial community called the gut microbiota. This microbiota, stable during the lifetime, is specific of each individual despite the existence of a phylogenetic core shared by the majority of adults. The influence of the gut microbiota on host's physiology has been largely studied using germfree animals and recently it has been proposed that the gut microbiota affects nutrient acquisition, energy regulation and fat storage. Indeed, germfree animals are resistant to diet induced obesity and display low levels of blood and liver lipids. In humans, several grams of lipids reach the colon each day. These lipids have an impact on the gut microbiota composition characterized by an increase of the Firmicutes/ Bacteroides ratio. Concurrently, the gut microbiota is able to convert lipids, including fatty acids or cholesterol, leading to the production of metabolites with potential health effects.
肠道菌群和脂质:对人体健康的影响人体肠道内有一个复杂而多样的细菌群落,称为肠道菌群。尽管存在大多数成年人共有的系统发育核心,但这种微生物群在一生中都是稳定的,对每个个体都是特定的。肠道菌群对宿主生理的影响已经在无菌动物实验中得到了大量的研究,最近有人提出肠道菌群影响营养获取、能量调节和脂肪储存。事实上,无菌动物对饮食引起的肥胖有抵抗力,并表现出低水平的血液和肝脏脂质。在人类中,每天有几克脂质到达结肠。这些脂质对肠道菌群组成有影响,其特征是厚壁菌门/拟杆菌门比例增加。同时,肠道微生物群能够转化脂质,包括脂肪酸或胆固醇,导致产生具有潜在健康影响的代谢物。

The content of docosahexaenoic acid (DHA) in brain membranes is of crucial importance for the optimum development of brain functions. A lack of DHA accretion in the brain is accompanied by deficits in learning behavior linked to impairments in neurotransmission processes, which might result from alteration of brain fuel supply and hence energy metabolism. Experimental data we published support the hypothesis that n-3 fatty acids may modulate brain glucose utilization and metabolism. Indeed rats made deficient in DHA by severe depletion of total n-3 fatty acid intake have 1) a lower brain glucose utilization, 2) a decrease of the glucose transporter protein content GLUT1 both in endothelial cells and in astrocytes, 3) a repression of GLUT1 gene expression in basal state as well as upon neuronal activation. This could be due to the specific action of DHA on the regulation of GLUT1 expression since rat brain endothelial cells cultured with physiological doses of DHA had an increased GLUT1 protein content and glucose transport when compared to non-supplemented cells. These experimental data highlight the impact of n-3 fatty acids on the use of brain glucose, thereby constituting a key factor in the control of synaptic activity. This emerging role suggests that dietary intake of n-3 fatty acids can help to reduce the cognitive deficits in the elderly and possibly symptomatic cerebral metabolic alterations in Alzheimer disease by promoting brain glucose metabolism.
脑膜中二十二碳六烯酸(DHA)的含量对脑功能的最佳发育至关重要。大脑中DHA的缺乏伴随着与神经传递过程损伤相关的学习行为缺陷,这可能是由于大脑燃料供应和能量代谢的改变造成的。我们发表的实验数据支持n-3脂肪酸可能调节脑葡萄糖利用和代谢的假设。事实上,由于严重消耗总n-3脂肪酸摄入而导致DHA缺乏的大鼠存在以下现象:1)脑葡萄糖利用率降低;2)内皮细胞和星形胶质细胞中葡萄糖转运蛋白GLUT1含量降低;3)GLUT1基因在基础状态和神经元激活时表达受到抑制。这可能是由于DHA对GLUT1表达调控的特异性作用,因为与未补充DHA的细胞相比,经生理剂量DHA培养的大鼠脑内皮细胞的GLUT1蛋白含量和葡萄糖转运增加。这些实验数据强调了n-3脂肪酸对脑葡萄糖使用的影响,从而构成了控制突触活动的关键因素。这一新的作用表明,饮食摄入n-3脂肪酸可以通过促进脑葡萄糖代谢来帮助减少老年人的认知缺陷,并可能减少阿尔茨海默病的症状性脑代谢改变。

Familial hypocholesterolemia, namely abetalipoproteinemia, hypobetalipoproteinemia and chylomicron retention disease (CRD), are rare genetic diseases that cause intestinal lipid malabsorption. They provide a model to study the consequences of chronic hypocholesterolemia: protection against cardiovascular disease, increase of fatty liver disease and neurovascular complications. The understanding of their physiopathology provided new approaches to treat hypercholesterolemia.

Mitigation of greenhouse gas emissions in the French winter oilseed rape in order to produce sustainable biodiesel 减少法国冬季油菜的温室气体排放,以生产可持续的生物柴油
Pub Date : 2012-05-01 DOI: 10.1051/OCL.2012.0453

The objectives of the study were (1) to evaluate the possibility for the French winter oilseed rape to achieve the 50% greenhouse gas (GHG) saving criteria of the European Directive on the promotion of renewable energy (2009/28/EC), and (2) to investigate mitigation options. The agricultural GHG emissions were calculated with the actual seed yields and cultural operations of more than 5000 winter oilseed rape fields producing seeds collected by 27 grain storage companies (GSC), while the same values of GHG emissions for transport and biodiesel processing were used for all GSC. The study clearly showed that the 50% GHG saving criteria could not be achieved each year, by each of the grain storage company, without improvements of crop management. The possibility to reduce the GHG emissions by improving the efficiency of mineral N fertilization was demonstrated. Improving seed yields without increasing the amount of N application on the fields would also decrease GHG emissions. On the contrary, the application of organic matter appeared to be largely ineffective because of the way N2O emissions were calculated in the study (tier 1 method of International Panel on Climate Change).
该研究的目的是(1)评估法国冬季油菜达到欧洲促进可再生能源指令(2009/28/EC)中50%温室气体(GHG)减排标准的可能性,以及(2)调查缓解方案。农业温室气体排放量是根据27家粮食储存公司(GSC)收集的5000多块冬季油菜田的实际种子产量和栽培作业来计算的,而所有GSC的运输和生物柴油加工温室气体排放量是相同的。该研究清楚地表明,如果不改进作物管理,每家粮食储存公司每年都不可能达到50%的温室气体减排标准。通过提高氮肥的施用效率,可以减少温室气体的排放。在不增加田间施氮量的情况下提高种子产量也会减少温室气体排放。相反,由于研究中计算N2O排放量的方式(国际气候变化专门委员会的第一级方法),有机物的应用似乎在很大程度上是无效的。

Continuous increases in the use of synthetic fertilisers and pesticides in agro-ecosystems have led to an increase in crop production, but also to a simplification of landscape and a decline in biodiversity at the field, cropping system level. Changes at landscape level, such as regional farm specialisation, increases in field size and the removal of hedgerows and woodlots suppression, have strengthened this tendency towards decline. The loss of biodiversity in agro-ecosystems has increased the need for external inputs, as important functions are no longer provided by beneficial species. This has led to an apparently inevitable reliance on petrochemicals in production systems. However, many scientists are arguing that this reliance on pesticides could be considerably reduced by making better use of biotic interactions. This review explores, in the light of recent studies, possible ways to increase beneficial biotic interactions in agro-ecosystems, and to improve bio control pest management at field and landscape scales. This review also points out the possible integrated cropping system on oilseed rape and concludes on the future research that has to be engaged to achieve the goal of improvement the natural bio-control of pests. For example at field scale, it has been shown that the choice of cultivar, the sowing date and nitrogen fertilisation practices can be manipulated to prevent interactions between pests and crop, in either time or space . We have also highlighted that beneficial biotic interactions may result from appropriate changes to the habitats of beneficial species, mediated by soil management and cover or mixing species utilisation. Finally, changes achieved at landscape scale appear promising. However, these approaches frequently also present drawbacks that may not necessarily be outweighed by the beneficial effects. Endly, we propose the approaches to design integrated crop management systems to reduce the damage of pests. However, major research efforts are required to quantify and to use the effects of management practices and to improve our understanding of the interactions between the different levels.
在农业生态系统中,合成肥料和农药的使用不断增加,导致了作物产量的增加,但也导致了农田种植系统层面的景观简化和生物多样性的下降。在景观水平上的变化,如区域农业专门化、农田面积的增加以及清除树篱和林地的压制,都加强了这种下降的趋势。农业生态系统生物多样性的丧失增加了对外部投入的需求,因为有益物种不再提供重要功能。这显然不可避免地导致了生产系统对石化产品的依赖。然而,许多科学家认为,通过更好地利用生物相互作用,这种对杀虫剂的依赖可以大大减少。本文根据最近的研究,探讨了在农业生态系统中增加有益生物相互作用的可能方法,以及在田间和景观尺度上改善生物防治病虫害的管理。本文还对油菜综合种植制度的可行性进行了展望,并对今后需要进行的研究进行了总结,以达到提高油菜自然生物防治害虫的目的。例如,在田间规模上,已经证明可以操纵品种的选择、播种日期和氮肥的施用,以防止害虫与作物在时间或空间上的相互作用。我们还强调,有益的生物相互作用可能源于有益物种栖息地的适当变化,由土壤管理和覆盖或混合物种利用介导。最后,在景观尺度上取得的变化似乎是有希望的。然而,这些方法也经常存在缺点,这些缺点不一定会被有益的影响所抵消。最后,提出了设计作物综合管理系统以减少有害生物危害的方法。然而,主要的研究工作需要量化和利用管理实践的影响,并提高我们对不同层次之间相互作用的理解。

Les biocarburants en Argentine : facteurs et enjeux de la production de biodiesel de soja 阿根廷的生物燃料:大豆生物柴油生产的因素和挑战
Pub Date : 2012-05-01 DOI: 10.1051/OCL.2012.0451
M. Guibert, S. Carrizo
In 2006, Argentina has sanctioned a national law to regulate biofuel production and consumption. Since 2007, soybean actors started producing biodiesel for international market -especially to Europe- and the country quickly became the major biodiesel exporter. In 2010, around twenty processing units started supplying the domestic market. Diesel sold in Argentina contained 5% of biodiesel. The obligation to add 5% of biodiesel to diesel has passed to 7% and the goal is to increase this percentage. The State support and soybean biodiesel competitiveness have been important for biodiesel chain development but some doubts could appear about the kind of actors that could have the benefits.
2006年,阿根廷批准了一项国家法律来规范生物燃料的生产和消费。自2007年以来,大豆生产商开始为国际市场(尤其是欧洲市场)生产生物柴油,该国迅速成为主要的生物柴油出口国。2010年,大约20家加工厂开始供应国内市场。在阿根廷销售的柴油含有5%的生物柴油。在柴油中添加5%生物柴油的义务已经超过了7%,目标是提高这一比例。国家的支持和大豆生物柴油的竞争力对生物柴油链的发展非常重要,但对于哪些行为者可以从中受益,可能会出现一些疑问。

Sustainable rapeseed production between science and politics 科学与政治之间的可持续油菜籽生产
Pub Date : 2012-05-01 DOI: 10.1051/OCL.2012.0445
O. Christen
The concept of sustainability, first developed in forestry, includes ecologic, economic and social aspects. In a number of international agreements almost all countries of the world have committed themselves to a sustainable development. The assessment of sustainability is normally done by using indicators. In the case of rapeseed special attention has to be placed on nitrogen balances and green house gas emission compared with other crops, however, a number of very positive effects of rapeseed occur if the scale of the crop rotation is considered. In recent years politics and administration have also used the term sustainability in the context of agricultural production, but only focussed on very few aspects and thus did not consider the complex system. This led to misconceptions and might cause disadvantages for rapeseed in the future. Based on the example of forestry, such a strong political influence might be avoided if the agricultural sector itself is able to establish assessment and certification systems.
可持续性的概念首先在林业中发展起来,包括生态、经济和社会方面。在一些国际协定中,世界上几乎所有国家都对可持续发展作出了承诺。可持续性的评估通常是通过使用指标来完成的。就油菜籽而言,与其他作物相比,必须特别注意氮平衡和温室气体排放,然而,如果考虑到作物轮作的规模,油菜籽会产生一些非常积极的影响。近年来,政治和行政部门也在农业生产的背景下使用可持续性一词,但只关注很少的方面,因此没有考虑到复杂的系统。这导致了误解,并可能在未来对油菜籽造成不利影响。根据林业的例子,如果农业部门本身能够建立评估和核证制度,就可以避免这种强烈的政治影响。
