Adjibade, Moufidath. "Etude des déterminants nutritionnels de la santé mentale dans deux cohortes françaises : SU.VI.MAX et NutriNet-Santé." Thesis, Sorbonne Paris Cité, 2018. http://www.theses.fr/2018USPCD058.
Full textDepression is a common mental disorder and the leading cause of disability worldwide. It has been associated with poor quality of life, physical decline, and increased risk of premature death. In addition, depression leads to a considerable economic burden, making it a major global public health. Protective and risk factors are diverse and include modifiable lifestyle indicators. Several studies have suggested that diet may play an important role in the risk of depression, but few of these studies have investigated the relationship between « a priori » dietary scores and depression. This thesis thus aims to investigate the relationship between overall diet quality evaluated using various nutritional « a priori » scores and incident depressive symptoms, using the data from SU.VI.MAX and NutriNet-Santé cohorts.Our findings showed an inverse association between adherence to the Mediterranean diet or nutritional recommendations (French and international) and the risk of incident depressive symptoms. However, the study on adherence to the Mediterranean diet showed significant results in men only. Moreover, « pro-inflammatory » diet was positively associated with the risk of incident depressive symptoms, but in the SU.VI.MAX cohort, the associations were significant only in some subgroups of the population: men, smokers and participants with low physical activity. We also showed that an increasing number of « healthy » lifestyle indicators was inversely associated with incident depressive symptoms.All of these findings suggest that promoting « healthy » lifestyles (including « healthy » diet) could be an important strategy in primary prevention of depressive symptoms

Full textA 2-factorial experiment, involving 3 levels of phosphorus (0, 40, and 80 kg P.ha-I ) as main treatment and 4 cropping systems (mono crop, maize/cowpea inter-row, maize/cowpea intra-row, and maize/cowpea intra-hole cropping) as sub-treatment was conducted in the field for 2 consecutive years in 2003 and 2004 to assess i) the effects of exogenous P supply and cropping system on the concentrations of plant-available nutrients in the rhizosphere of cowpea and maize; ii) the effect of exogenous P supply on tissue concentrations of minerals in nodulated cowpea and maize in mixed plant cultures iii) the effects of exogenous P supply and cropping system on plant growth and N2 fixation, and iv) the effects of exogenous P supply and cropping system on phosphatase activity and microbial biomass in the rhizosphere of cowpea and maize. At harvest, it was found that applying 40 or 80 kg P.ha-I significantly increased cowpea grain yields by 59-65% in 2003 and 44-55% in 2004. With maize, the increases in grain yield were 2037% in 2003 and 48-55% in 2004 relative to zero-P control. In both cropping seasons, the number of pod-bearing peduncles per plant, the number of pods per plant, the number of seeds per pod, and seed yield per cowpea plant were significantly increased with the application of exogenous P. In contrast, these parameters were all significantly depressed by mixed culture relative to mono crop cowpea. Intercropping maize with cowpea produced higher total yields per unit land area than the sole crop counterpart.

Full textAnorexia nervosa (AN) is an eating disorder (ED) with female predominance, mainly characterised by a decrease of food intake leading to a severe body weight loss. Furthermore, psychiatric comorbidities are frequently observed in AN patients such as depression and anxiety. During the last decade, the role of microbiota-gut-brain axis in ED and anxiety-like behavior has emerged. Several studies reported gut microbiota dysbiosis in anorectic patients. Nevertheless, the pathophysiology of AN remains poorly understood. The aim of the present PhD thesis was to better understand the contribution of the gut microbiota in the regulation of gut-brain axis in the mouse model of anorexia "activity-based anorexia" (ABA). The ABA model combines spontaneous physical activity with a free running wheel access and a progressive limited food access. In a first study, we characterised the gut microbiota of C57Bl/6 male mice submitted to ABA model. We observed in ABA mice an increase of Lactobacillus and clostridium cocleatum belonging to genus of Clostridium, as well as a decrease of Burkholderiales. Interestingly, correlations between bacteria taxa and food intake, body weight and body composition have been observed. Then, we aimed to evaluate the response to ABA model of mice with gut microbial depletion. We thus compared in a second study different dosing and administration of large spectrum antibiotic treatments, either by oral gavages (once or twice a day) or by addition in drinking water. Although these three strategies led to a strong decrease of faecal bacteria, once day oral gavage induced proliferation of Gammaproteobacteria. Thus, antibiotics administration by oral gavage twice a day or in drinking water appear as the most appropriate modes to achieve gut microbiota depletion. In a third study, we then evaluated the response to ABA model of both male and female C57Bl/6 mice with antibiotic-induced microbiota depletion. Firstly, we observed that antibiotic administration led to an increase of fat mass and a decrease of lean mass. During the ABA model, gut microbiota-depleted mice exhibited a lower decrease of body weight compared to untreated ABA mice. In males, we also observed altered anxiety-like behavior in ABA mice with depleted gut microbiota. We thus showed that gut microbiota-depleted mice exhibited an altered response to ABA model in a sex-dependent manner. Finally, in order to decipher the underlying mechanisms, we focused on toll-like receptor 4 (TLR4), an endogenous receptor of lipopolysaccharides. Previous studies suggested TLR4 implication in the regulation of feeding and anxiety-like behaviors. To determine the involvement of intestinal TLR4, we submitted mice with intestinal epithelial TLR4 knockout to the ABA model. Again, we observed a sex-dependent response: a delayed and limited body weight loss in males and an increase of anxiety-like behavior in females. In conclusion, studies performed during this PhD thesis highlight the alterations and the role of gut microbiota in the activity-based anorexia model that appear to be sex-dependent

Full textThe larval nutritional mode of marine invertebrates is an important life history trait that has strong effects on their ecology and evolution. Increases in egg size and transitions from feeding to nonfeeding larvae have happened repeatedly. In Spiralia, a change in cytoplasm allocated to macromeres at the 8-cell stage (that could delay the development of a functional gut) may accompany these transitions. The first part of this thesis describes the development of the gastropod Crepidula williamsi and compares it to the closely related C. fornicata, with a focus on changes in allocation to macromeres and the development of a functional gut. The second part is a phylogenetic comparison of egg size and allocation to macromeres in 44 species of spiralians, which revealed a significant correlation between the two. A phylogenetic comparison like this one has not previously been done on the development of such diverse marine invertebrate taxa.

Full textSHAW, JU-JEAN. Bioavailability of Oil-Based and ß-Lactoglobulin Complexed Vitamin A in a Rat Model. (Chair: Jonathan C. Allen and Co-chair: Harold E. Swaisgood)The goal of this research was to determine the bioavailability of a retinyl palmitate-ß-lactoglobulin complex in fortified skim milk and non-milk liquids using a rat model. Vitamin A plays a crucial role in many biological functions such as vision, cell differentiation, gene expression, central nervous system development, bone development and immune system function. Fluid milk products have been fortified with vitamin A (along with Vitamin D) since the 1930s to reduce the incidence of disorders caused by fat-soluble vitamin deficiency in the USA. Low-fat and non-fat fluid milk products are fortified with vitamin A and other nutrients to restore that which is removed with the lipid phase. Vitamin A preparations for milk fortification have either oil-based carriers or water-based carriers. Although it was suggested that the oil-in-water emulsions are preferred rather than oil-based preparation, vitamin A- fortified milk is often unable to comply with nutrition labeling requirements. Because retinyl palmitate, a vitamin A form most used in food products, can bind with ß-lactoglobulin, a major component of bovine whey, in a molar ratio of 2:1, we propose ß-lactoglobulin could be a carrier to fortify skim milk with retinyl palmitate. The bioavailability of this vitamin A-ß-lactoglobulin complex has not been tested yet so we designed and conducted experiments to test the bioavailability of this complex in the skim milk and water-based liquids.

Full textProanthocyanidins have been shown to exert advantageous actions on several metabolic disorders that are risk factors of cardiovascular diseases. Lipoprotein metabolism plays an important role in altered lipid states. Therefore, the aims of this Thesis were: To assess the contribution of the liver and the intestine in the hypolipidemic response triggered by proanthocyanidins and to evaluate the short-term effect of an oral intake of proanthocyanidins in dyslipidemic nutritional models. For these purposes, three experimental models have been used: Rats, mice and human Caco2 cells. The obtained results are: In a fat tolerance test, both chylomicrons and VLDL contribute to the hypotriglyceridemic action of proanthocyanidins but their influence depends on time. Moreover, proanthocyanidins repress TG secretion by the liver in vivo and by the intestine in vitro. Furthermore, ACSL manifests as their target gene in intestinal cells. Finally, proanthocyanidins correct dyslipidemia but not the weight gain induced by diet though these have a bimodal effect on energy retention in vivo.

Full textThe reduced folate carrier I (RFC1) is responsible for the cellular uptake and intestinal absorption of folate, primarily the 5-methyltetrahydrofolate (5-methylTHF) derivative. Methionine synthase (MTR) uses 5-methylTHF to remethylate homocysteine to methionine, which may be activated and used to methylate substrates such as DNA. 5-MethylTHF is also the product of the methylenetetrahydrofolate reductase (MTHFR)-catalysed reduction of 5,10-methyleneTHF, which is also used to convert dUMP to dTMP.
Adenoma number and load were reduced in Rfc1+/-Apc min/+ mice, compared with Rfc1+/+Apc min/+ mice, but were similar in Mtr+/-Apc min/+ and Mtr+/+ Apcmin/+ mice. Neither Rfc1 nor Mtr genotype affected global DNA methylation, apoptosis or plasma homocysteine (tHcy) levels. In the experiments involving Mtr mice, dietary folate deficiency increased adenoma number, plasma tHcy, and apoptosis, and decreased global DNA methylation. Neither Mtr nor Rfc1 genotype affected the dUTP/dTTP ratio in the intestine of mice not predisposed to adenoma formation.
Adenoma number was decreased in Mthfr+/-Apc min/+ mice (compared with Mthfr+/+Apc min/+ mice) and in Mthfr+/+Apc min/+ offspring of Mthfr+/- mothers (compared with Mthfr+/+Apcmin/+ offspring of Mthfr+/+ mothers). A folate-deficient diet, when initiated prior to conception, significantly decreased adenoma number and decreased global DNA methylation. Overall, adenoma number was inversely correlated with plasma tHcy, dUTP/dTTP ratio and apoptosis. When initiated at three weeks of age, a folate-enriched diet significantly increased adenoma number in Apcmin/+ mice. In the intestines of mice not predisposed to adenoma formation, Mthfr deficiency decreased, and folic acid deficiency increased, the dUTP/dTTP ratio.
These results support the evidence that MTHFR polymorphisms are protective in CRC tumourigenesis and that depending on stage or predisposition, folate may inhibit or enhance tumour growth.

Full textLe glutathion est l'un des principaux antioxydants de l'organisme. Il est produit de façon endogène à partir de glutamate, de cystéine et de glycine. La maladie inflammatoire de l'intestin est une condition débilitante associée au stress oxydatif et à la malnutrition protéique et énergétique (MPE), surtout chez les enfants. La présente étude avait pour but d'examiner l'effet de la nutrition et de l'inflammation intestinale sur l'état du glutathion dans les érythrocytes et les tissus en utilisant un modèle de colite induit par dextrane sulfate de sodium (DSS) chez des porcelets. Cette étude est la première à combiner l'utilisation d'isotopes stables pour déterminer la synthèse du glutathion et la spectrométrie de masse pour analyser la concentration du glutathion et de ses métabolites dans divers modèles de malnutrition et de colite pédiatrique. Nos résultats ont démontré que glutathion est uniquement régulé dans les tissus des porcelets sains, la majorité du glutathion étant produit dans le foie. La concentration de glutathion était inférieure d'environ 20% dans le côlon distal de porcelets bien nourris souffrant de colite par rapport aux porcelets sains et inférieure d'environ 60% chez les porcelets avec MPE par rapport aux porcelets bien nourris. Seulement un déficit sévère en protéines a compromis le métabolisme du foie et la concentration de glutathion dans les érythrocytes, la muqueuse iléale et le côlon spiralé. Aucun effet sur la régulation du glutathion n'a été démontré chez les porcelets recevant des protéines de différentes qualités, chez des porcelets avec MPE recevant une supplémentation probiotique ou une hormone anabolisante. En conclusion, nous avons démontré que la malnutrition protéique, une conséquence fréquente de l'inflammation intestinale, exacerbe les effets délétères de l'inflammation sévère en affectant la régulation du glutathion. La consommation adéquate de protéines peut jouer un rôle plus bénéfique que l'augmentation des macronutriments sur la régulation du glutathion. Ceci souligne le rôle de l'intervention nutritionnelle, spécifiquement l'augmentation de la cystéine, comme une approche thérapeutique à la réhabilitation des patients avec la maladie inflammatoire de l'intestin.

Full textThe thesis addresses two major issues. Firstly: The study the effects of polyphenol-rich peanut extract and bioactive compounds (alpha-tocopherol) in cellular models of inflammation (monocytic cells; THP-1) and on endothelial dysfunction (human aortic endothelial cells; HAEC), respectively. Secondly: The optimisation of blood sampling for human studies to characterise the profile of aqueous and lipid metabolites, fatty acid composition, lipoprotein subclasses, and polyphenol content of plasma and red blood cells. Peanut extract exerts anti-inflammatory effects by inhibiting extracellular TNF-α protein via the inhibition of c-Jun transcription factor activation. Alpha-tocopherol improves endothelial function by inhibiting VCAM-1 and, to a lesser extent, E-selectin and ICAM-1. Analyses of metabolites in plasma and red blood cells generate complementary information. The measurements may need to be performed in either, or both, matrices, depending on the objectives of the study.

Full textUn modèle de colite expérimentale provoquée par le dextran sulphate de sodium (DSS) chez le porcelet a été employé pour étudier sur les effets d'une déficience modérée (DM) ou sévère (DS) en protéines sur la sévérité de la maladie dans le colon distal et spiral, la croissance, la composition corporelle, l'équilibre azoté et les taux de synthèse fractionnelle des protéines plasmatiques, du foie et tissus. DM n'a pas affecté la croissance linéaire ni la circonférence de la poitrine. En revanche, DS a sévèrement affecté le gain de masse corporelle, la croissance et la composition corporelle des porcelets. L'histopathologie du colon distal n'a révélé aucun effet du statut protéinique, alors que DS a sévèrement compromis l'intégrité du colon spiral. Les porcelets MD ont pu maintenir les taux de synthèse de protéines hépatiques et de la majorité des tissus. Par contre, la synthèse de protéines des tissus viscéraux, mesurée par infusion constante du tracer isotopique L-[ring-2H5]phenylalanine, a été remarquablement diminuée par DS de 50 a 70% chez les porcelets DSS comparés aux porcelets WN. DS, et non DM, a sévèrement retardé la croissance et a aggravé la sévérité de l'inflammation du colon spiral dans ce modèle animal de colite.

Full textL'objectif de cette thèse est d'étudier les réponses biologiques musculo-squelettiques de l'acide linoléique conjugué (ALC). Méthodologie: Étude 1: Des rats Sprague-Dawley ont été randomisés pour recevoir le régime de contrôle AIN-93 ou le même régime supplémenté avec 0,5% c9, t11 + 0,5% t10, c12 d'ALC en forme d'AGL ou de TG. Les profils d'acides gras du foie ont été évalués pour l'incorporation de l'ALC dans les tissus. Les biomarqueurs osseux ainsi que la densité osseuse et la composition corporelle ont été mesurés après 4, 8, 16 semaines. Étude 2: Des rats Sprague-Dawley ont été randomisés au sevrage pour recevoir le régime de contrôle AIN-93 ou le même régime supplémenté avec 0,5% c9, t11 + 0,5% t10, c12 d'ALC en AGL pendant 16 semaines. Du sang a été recueilli à la fois dans un état nourri et à jeun. La PTH a été évaluée à l'aide de test de la PTH de deuxième et de troisième génération. Étude 3: Des hommes âgés de 19 à 53 ans (n = 31) ont été randomisés en double aveugle, lors d'un essai clinique contrôlé pour recevoir: 1,5 g / j ou 3,0 g / j de c9, t11 (4:1 c9, t11 à t10, c12 rapport d'isoforme) ou un placebo (huile d'olive 3 g / j) pendant 16 semaines. L'absorptiométrie biphotonique à rayons X (DXA) a été réalisée pour évaluer la composition corporelle. Des échantillons de sang ont été obtenus mensuellement pour évaluer les changements dans la concentration de la PTH, la 25-hydroxy-vitamine D (25(OH)D), l'iCa, le phosphate et le profil lipidique. Étude 4: En tant que modèle de vieillissement avancé, des cochons d'inde pigmentés (n = 40) on été randomizés à 70 semaines d'âge à 4 groupes: 1) chirurgie fictive (SHAM) + Régime de contrôle (CTRL), 2) SHAM + régime d'ALC (ALC) (1,0% 4:1 c9, t11 à t10, c12 rapport d'isoforme), 3) orchidectomie (ORX) + CTRL, 4) ORX +ALC. L'analyse de la densité osseuse et la composition corporelle (par DXA) ainsi que des échantillons sanguins recueillis pour mesurer la testostérone, l'estrogène, l'interleukin-6 (IL-6), ont été. À 16 semaines, l'iCa et la 25(OH)D ont été évaluées ainsi que, la microarchitecture osseuse utilisant la microtomodensitométrie, la force des os ainsi que le taux de synthèse protéique fractionnaire dans les muscles squelettiques en utilisant une dose d'inondation de 40% en moles de L-[ring-2H5]-phénylalanine (1,5 mmol / kg ip). Résultats: Étude 1: Il n'existe aucune différence entre les groupes pour les biomarqueurs et la masse osseuse, ni l'équilibre minéral. L'enrichissement du foie en c9, t11 sous forme AGL était plus grand que sous forme de TG et AIN-93. Étude 2. Chez les mâles et les femelles, il n'y avait pas de différence entre les rats nourris et à jeun lorsque la PTH était évaluée en utilisant le test PTH INT. Cependant, chez les femelles seulement, la PTH mesurée à l'aide de la PTH Bioactive, était significativement plus faible dans le groupe nourri par rapport au groupe à jeun. Étude 3: Les hommes avec un statut d'ALC c9, t11 dans les globules rouges au dessus de la médiane avait une densité minérale osseuse (DMO) du corps et un pourcentage de masse maigre du corps plus élevé, alors que l'indice de masse corporelle (IMC) et le pourcentage de masse grasse corporelle étaient plus bas. Dans l'analyse de régression, le statut d'ALC c9, t11 dans les globules rouges représentait une proportion significative (r2 = 0,10) de la variation de la DMO du corps entier (P = 0,03). Il n'y avait pas de différence temporel et de traitement pour n'importe quel autre mesure d'os ou de biomarqueurs du métabolisme osseux, y compris la PTH. Étude 4: L'ALC a empêché la perte de la densité osseuse et du volume osseux métaphysaire ainsi que l'augmentation de la porosité diaphysaires observés après l'orchidectomie. Également, aucunes différences dans les taux de synthèse fractionnaire des protéines myofibrillaires et sarcoplasmiques n'ont été détectées. Signification: Dans l'ensemble, des petits avantages de l'ALC sur la perte d'os et de muscles ont été observés.

Full textObjectifs La bonne nutrition et les probiotiques ont prouvé réduire la sévérité de la colite. Cependant, leur impact sur le métabolisme des protéines gastro-intestinales et hépatiques n’a pas encore été étudié. Notre objectif premier était de comparer l’effet indépendant des probiotiques à celui d’un régime alimentaire adéquat, sur la synthèse des protéines, chez le porcelet présentant une colite, recevant une diète restreinte en macronutriments. Le but secondaire de cette étude était de déterminer les contrastes histologiques ainsi que les variations au niveau des marqueurs du stress oxydatif, résultant de l’effet des probiotiques dans les deux cas de malnutrition et de nutrition adéquate. Nous avons aussi mesuré l’équilibre et les concentrations de cuivre, fer et zinc dans le plasma durant les 5 jours de colite, dans le but de déterminer comment les probiotiques et la colite affectent tous deux la balance des oligo-éléments. Méthodes et analyses Vingt-quatre porcelets, recevant 1g/kg/jour de sulphate de dextran (DS), ont été randomisés en quatre groupes : deux groupes recevant une diète appauvrie en macronutriment à 50%, avec (MR+PRO) ou sans (MR) probiotiques, et un groupe recevant une diète contenant 100% des besoins nutritionnels pour porcelets, suivant les standards NRC (WN). Un quatrième groupe comprenant huit porcelets recevant une diète adéquate et ne présentant pas de colite (REF) a été inclus à des fins de comparaisons histologiques ainsi qu’au niveau des oligo-éléments. Une infusion constante du traceur L-[ring-2H5]phenylalanine a été effectuée pour déterminer la synthèse des protéines de la muqueuse de l’intestin grêle, colon, foie et plasma. Les techniques de « staining » standard, in situ et immunohistologiques ont été utilisées pour les déterminations histologiques, et des analyses du pouvoir antioxydant, ELISA F2-isoprostane assay, ainsi que le ratio cuivre:zinc ont été$
