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.

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.

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.

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).

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.

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.

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.
