A brain mechanism involved in mediated learning is identified

Researchers from INRA and INSERM have just identified the brain mechanism involved in the mediated learning process. Their results, published online on 30 August 2018 in Neuron, show that cannabinoid receptors in the hippocampus play a key role in establishing these types of associations.

The influence of genetics on nutritional requirements

Approximately 0.1%: that is the average genetic difference between two individuals. This small percentage is responsible for the variations of certain physical traits, such as eyes, hair, and height, but also for differences in our susceptibility to certain diseases and our capacity to absorb vitamins and phytomicronutrients (carotenoids, polyphenols, etc.), involved in the prevention of chronic disease. Based on the study of genetic interindividual variability, researchers from INRA and Aix-Marseille University have published a review on current knowledge of nutrigenetics in the Annual Review of Nutrition on 21 August 2018. The objective of this emerging science is to personalize nutritional recommendations in order to optimize nutrient, micronutrient, and phytomicronutrient allowances by taking into account genetic differences between individuals and groups of individuals.

The effect of a cocktail of low-dose pesticides via the diet: initial findings in animals have demonstrated metabolic disturbances

INRA scientists, working with their colleagues from INSERM, have studied in mice the effects of chronic oral exposure to a low-dose pesticide cocktail. Their results have demonstrated metabolic disturbances in vivo that differ as a function of sex. Indeed, males exposed to the pesticides gained weight and became diabetic, while females were protected from these effects but displayed other disturbances. These results have just been published in the journal Environmental Health Perspectives.
