Texto completoPopulation’s aging represents one of the world's greatest economic, societal and public healthchallenges. By 2050, more than a billion people worldwide will be aged 60 or over, making it all the moreimportant to age well. In this context, age-related cognitive decline, characteristic of aging, is a criticalfactor to be considered in order to improve the quality of life of the elderly and prevent loss of autonomy.One promising approach is to propose nutritional strategies. Among existing bioactive nutrients,polyphenols from berries (grapes, blueberries), saffron compounds and n-3 polyunsaturated fatty acids(n-3 PUFAs) from fish are recognized for their beneficial properties on memory functions.The aim of this thesis was to evaluate the efficacy of a combination of these nutrients in preventingage-related cognitive decline, and to understand the neurobiological mechanisms involved. We targetedthe hippocampus, a key brain structure involved in memory processes and particularly impaired duringaging. Our main results showed that a combination of berry polyphenols, saffron compounds and n-3PUFA extracts in aged mice effectively prevented both short- and long-term memory impairment. Theseresults were associated with improved neuronal plasticity and neurogenesis, including an increase inDCX, a marker of immature neurons, and up-regulation of signalling pathways involved in synapticdevelopment and function. These beneficial effects can be explained by the modulation of several keybiological processes.Indeed, the nutrient combination showed a powerful anti-inflammatory effect by regulatinginflammatory lipid mediators, notably pro-resolving oxylipins (18-HEPE, 17-HDHA, 14-HDHA) in adultmice during of acute inflammation, and by inhibiting inflammation-related signaling pathways in agedmice during of chronic inflammation. In addition, it limited oxidation by increasing the expression ofantioxidant enzymes such as catalase, superoxide dismutase and glutathione peroxidase in adult mice inresponse to acute inflammation or treatment inducing accelerated aging, and by inhibiting oxidativestress-related signalling pathways in aged mice. We also demonstrated that the gut microbiota may playan important role in these effects via the gut-brain axis. In particular, we have demonstrated an increasein bacteria favorable to cognitive health, and a decrease in those associated with inflammation andmemory impairment. Finally, this work has enabled us to identify a pool of genes whose expression wasincreased during aging in the hippocampus and was negatively correlated with cognitive performance.These genes could serve as biomarkers of cognitive decline. Interestingly, their expression wasdiminished by the combination of nutrients. Thus, our study demonstrates that the combination of berry polyphenols, bioactive saffroncompounds and fish n-3 PUFAs prevents memory impairment by acting on various major neurobiologicalprocesses of aging. This multi-targeted nutritional approach has great potential for preventing agerelatedcognitive decline and promoting healthy aging. These results pave the way for new nutritionbasedpreventive strategies to combat the effects of cerebral aging

Texto completoThis phd manuscript presents an original and highly collaborative research work on norbadione a, a fungal pigment which was isolated from pisolithus arhizus. This study was undertaken in order to gain insight into complexation, exchange and accumulation of radionuclides (137cs) or heavy metals (cd(ii), ni(ii), pb(ii)). This subject required interdisciplinary expertise (mycology, natural products extraction and characterisation, organic traces analysis, physicochemistry) and was using the most recent developments of analytical methods (spectrophotometry, nmr, mass spectrometry, potentiometry, cyclic voltammetry). Our results were published in chemical communications, highlighted in nature and emphasised in different press articles (l'express, the guardian,. . . ). Our results revealed that in the p[h] range (between 6. 0 and 6. 5) which is typical for mushrooms, the major species of free norbadione a is the dienolate form. We showed that norbadione a was able to accumulate monovalent cations (cs+, k+, tl(i)) due to allosteric properties which favors the formation of bimetallic complexes. On the other hand, norbadione a forms mononuclear complexes with heavy metals like cd(ii), ni(ii) and pb(ii), the corresponding dinuclear analogs being less stable for electrostatic reasons. The natural dipotassic norbadione a complex exchanges its potassium cations with caesium or thallium(i), as shown by electrospray mass spectrometry. Finally, we determined for norbadione a an antiradicalar power comparable with that of the most abundant polyphenols present in fruits and vegetables and a moderate antioxidant activity

Texto completoWe isolated, identified the epicatechin, the catechin, dimers B2 and B5 of the cocoa, in order to study their properties on the cancerous cells T47D. These compounds are potential agonists of membrane androgen receptors and could be used as testosterone-protein conjugates for the management of tumors, in which, application of testosterone-BSA induces regression. We determined the presence in chocolate of chiral compounds as: (+)-catechin, (-)-catechin, (-)-epicatechin, dimers B2 and B5. The hemi synthesis of monomers from cocoa gave the following enantiomers: (+)-epicatechin and (-)-catechin. The rearrangement of the dimer B2 give: epicatechin, (-)-catechin and the 8,9- cis-9-14-trans-3,4,9,1O-tetrahydro-2H,8H-pyrano[2,3-h]chromene, of which results on the cancerous cells U266, K562, THP1 and Rajis, are very near of those of the resveratrol. We can say that it could have a biologic interest of the industrial treatments of the chocolate for the consumer

Texto completoLa nourriture issue de la chasse ou de la pêche comporte plusieurs nutriments essentiels à une bonne santé. Toutefois ces aliments peuvent aussi contenir des concentrations importantes en contaminants tel que le mercure et le plomb, qui posent un risque pour la santé. Pour guider les communautés qui basent leur alimentation sur la chasse ou la pêche, l’objectif global du projet est de développer une plateforme analytique permettant le suivi de la qualité alimentaire dans les environnements nordiques. Pour ce faire, une stratégie analytique de dissolution de la chair animale pouvant être employée à l’extérieur d’un laboratoire par des non scientifiques a été mise en place. Cette stratégie comporte l’échantillonnage, la mise en solution de la chair et la séparation des analytes pour effectuer leur analyse ainsi que le changement de matrice, en plus de la détection et de la quantification des analytes par fluorimétrie. Toutefois, puisque les systèmes de détection visés pour la plateforme sont en développement, une méthode de quantification du plomb et du mercure par ICP-MS/MS a aussi été développée. Cette stratégie analytique a été élaborée pour l’analyse de l’omble chevalier, un poisson consommé à l’année dans certaines communautés nordiques dans lequel les concentrations en contaminants sont très variables. Le processus analytique, de l’échantillonnage à l’obtention d’une solution mono élémentaire en passant par l’analyse ICP-MS/MS et la dissolution de la chair d’omble chevalier, sera décrit dans ce mémoire.
Fish and game meat contain different essential nutriments for a good health. However, it can also contain contaminants, such as mercury and lead, that pose a health risk. To guide the communities that base their diet on hunting or fishing, the main objective of the project is to develop a portable analytical platform that allows the monitoring of contamination by heavy metals of country food on the field. To this end, an analytical strategy for the dissolution of food flesh that can be deployed outside of the laboratory and used by non-scientists has been established. This strategy includes sampling, flesh dissolution, analyte separation and matrix exchange for the analysis in addition to fluorimetric detection and quantitation of the analytes. Since the quantification system for this platform is still under development, we therefore developed an ICP-MS/MS method to quantify lead and mercury in our food extracts. This method was developed to analyze arctic char, a fish consumed all year long in some northern communities and in which the contamination level can vary significantly. The analytical process from sampling to monoelemental analysis by ICP-MS/MS will be discussed in this document.

Texto completoThe present study is the first in Lebanon to evaluate, by the market basket approach, the contamination of foods by radionuclides and heavy metals and the dietary exposure of the Lebanese population to the heavy metals Pb, Cd and Hg. An individual dietary survey has been realized on 444 adult individuals living in Beirut. Food consumption data were collected using a quantitative food frequency questionnaire. The market basket was identified by selecting those foods with a mean daily intake exceeding 1g/day. The contamination levels of the selected foods with heavy metals and radionuclides were assessed. The results show that the level of radioactivity of the analyzed food does not present any concern for public health. The average dietary exposure of the average individual to Pb, Cd, and Hg corresponds to 7,17 and 6 % of the respective PTWIs. This permits to conclude that, for the average individual, there is no risk of exceeding the PTWIs
