Alcoholic beverages, obesity, physical activity and other nutritional factors, and cancer risk: A review of the evidence
2016
International audience; Purpose: Prevention is a priority in the fight against cancers, especially nutritional prevention. To update the levels of evidence of relationships between 10 nutritional factors and cancer risk, the scientific literature published from 2006 to 2014 was reviewed by an expert group.Methods: Data from 133 meta-analyses, pooled analyses or intervention trials were examined. Nearly 150 relationships between nutritional factors and cancer at various sites were evaluated.Results: According to the evidence graded as convincing or probable, these factors were divided in two groups. Factors which increase the risk of cancer are alcoholic beverages, overweight and obesity, re…
Postprandial adaptation of intestinal lipid metabolism : role of CD36 and PPAR beta
2011
Postprandial hypertriglyceridemia is an emerging risk factor for cardiovascular diseases and is associated with metabolic syndrome, obesity and insulin resistance. The small intestine participates in the postprandial triglyceridemia since both the size and number of secreted chylomicrons modulate lipoprotein lipase activity (LPL). Chylomicron synthesis is a complex mechanism in which the lipidation of Apolipoprotein B48 (ApoB48) by the Microsomal Triglyceride Transfer Protein (MTP) and the transfer between reticulum and Golgi in which the Liver Fatty Acid Binding Protein (L -FABP) is involved are limiting steps. An intestinal fat-mediated adaptation in postprandial period has been demonstra…

The plant resistance inducer β-aminobutyric acid (BABA) induces an iron deficiency response in A. thaliana
2012
β-aminobutyric acid (BABA) is a well-known plant resistance inducer. However, the molecular mechanisms underlying its effects are poorly understood. In the present study, we investigated whether BABA could act through the modification of iron homeostasis in Arabidopsis thaliana. Supporting this assumption, we obtained first evidences that BABA chelates iron with high affinity. We showed that pre-treatment of plants with BABA induced a drastic but transient iron deficiency response. Quantification of iron indicated that this response is related to the perturbation of iron distribution/availability rather than a reduction of iron assimilation. Finally, we provided evidence that the iron defic…
Spatial distribution of ammonia-oxidizing bacteria and archaea across a 44-hectare farm related to ecosystem functioning
2011
Characterization of spatial patterns of functional microbial communities could facilitate the understanding of the relationships between the ecology of microbial communities, the biogeochemical processes they perform and the corresponding ecosystem functions. Because of the important role the ammonia-oxidizing bacteria (AOB) and archaea (AOA) have in nitrogen cycling and nitrate leaching, we explored the spatial distribution of their activity, abundance and community composition across a 44-ha large farm divided into an organic and an integrated farming system. The spatial patterns were mapped by geostatistical modeling and correlations to soil properties and ecosystem functioning in terms …
