Full textChronic Inflammation can play an important role in the development of the pathogenesis related with obesity. It has been demonstrated that some probiotics (Lactobacillus, Bifidobacterium) can prevent obesity and inflammation by reducing the liberation of LPS by intestinal epithelial cell. Probiotic have reduced adipose cells weight (size) by decrease the liberation of pro-inflammatory cytokine (IL-6, TNF-α). No dairy product containing anti-inflammatory and anti-obesity probiotics are currently available in North America. The viability of probiotic is important during the manufacture and the storage of dairy product since cheese (50 g) and yogurt (100 g) must contain at least 109 colony forming unity (cfu) of the specific probiotic strain with health claims. This study focuses on the viability and technological, anti-inflammatory and anti-obesity properties of new probiotic strains in low-fat yogurt and Cheddar cheese. To obtain a good viability, it is important to select the best combination of thermophilic strains to constitute a yogurt starter or Lactococcus strains to constitute a cheese starter to be compatible with probiotics. Bifidobacteria strains had more difficult to maintain a target population of 109 bacteria per serving cheese or yogurt than lactobacilli strains. Among five probiotic candidates, Bifidobacteria animalis ssp. lactis Bf141 and Lactobacillus rhamnosus Lb102 have demonstrated the best anti-obesity and technological properties in dairy products. The both probiotic strains survived to the gastrointestinal passage. The reduction of body weight gain and white adipose tissue of mice was more important with probiotics milks than milk without probiotic. Weight reduction was greater with Bf141 strain. The anti-obesity effect was greater with milks than with yogurts. Milk was therefore a better vector than yogurt for probiotic bacteria with anti-obesity effect.

Full textLes objectifs de cette thèse étaient d’évaluer les effets d’un supplément combiné d’acide folique et de vitamine B12 sur les performances zootechniques en fermes laitières (première étude) et sur la cinétique du glucose en début de lactation (deuxième étude). Les traitements suivants ont été donnés par injections intramusculaires hebdomadaires de trois semaines avant le vêlage jusqu’à huit ou neuf semaines postpartum : pour la première étude 1) saline ou 2) acide folique et vitamine B12 et pour la deuxième étude 1) saline; 2) acide folique; 3) vitamine B12; ou 4) acide folique et vitamine B12. Pour la première étude, 805 vaches dans 15 troupeaux ont été impliquées. L’incidence de dystocie a été plus basse et la première insémination postpartum a eu lieu plus tôt pour les vaches multipares recevant le supplément que pour les vaches multipares ne le recevant pas. Le supplément n’a pas eu d’effet sur la production laitière. Toutefois, la concentration en gras du lait a diminué et celle en protéines a augmenté pour les vaches recevant le supplément. De plus, ces vaches ont perdu moins de poids corporel en début de lactation suggérant un effet du supplément sur la répartition de l’énergie. L’analyse économique a indiqué que ce supplément a été rentable pour la moitié des fermes à l’étude. Le supplément a augmenté la concentration en vitamine B12 du lait dans tous les troupeaux. Pour la deuxième étude, 24 vaches multipares ont été utilisées. Les concentrations plasmatiques de folates et de vitamine B12 des animaux témoins étaient plus élevées que ce qui a été rapporté dans la littérature. Étonnamment, le supplément d’acide folique a diminué le taux d’apparition du glucose à la neuvième semaine postpartum. L’ingestion, la concentration en glycogène hépatique et le pourcentage de glucose synthétisé provenant du propionate étaient semblables entre les traitements. Les résultats de ces études indiquent que, sous certaines circonstances, les apports d’acide folique et de vitamine B12 par la microflore du rumen semblent adéquats pour optimiser les performances des vaches. Cependant, il n’existe actuellement aucun moyen de prédire les apports en ces vitamines pour l’animal selon la ration reçue.
The objectives of this thesis were to evaluate the effects of a combined supplement of folic acid and vitamin B12 on performance in commercial dairy herds (first study) and on glucose kinetic in early lactation (second study). The following treatments were given by weekly intramuscular injections from three weeks before calving until eight or nine weeks postpartum: for the first study 1) saline or 2) folic acid and vitamin B12 and for the second study 1) saline; 2) folic acid; 3) vitamin B12 or; 4) folic acid and vitamin B12. For the first study, 805 cows in 15 herds were involved. The incidence of dystocia was lower and the first breeding postpartum occurred at an earlier time for multiparous cows receiving the vitamin supplement than for multiparous cows that did not. Vitamin supplement did not affect milk production. However, milk fat concentration decreased and milk protein concentration increased for dairy cows receiving the supplement. Moreover, these cows lost less body weight in early lactation suggesting an effect of the vitamin supplement on energy partitioning. The economic analysis showed that this supplement was profitable for half of the studied herds. The vitamin supplement increased vitamin B12 concentration in milk within each herd. For the second study, 24 multiparous cows were involved. Plasma concentrations of folates and vitamin B12 from controls were higher than previously reported in the literature. Surprisingly, the folic acid supplement decreased whole-body glucose rate of appearance at week nine postpartum. However, dry matter intake, liver glycogen concentration, and percentage of glucose synthesized from propionate were similar among treatments. Results from these two studies highlighted that, under some circumstances, supplies of folic acid and vitamin B12 from ruminal microflora seem to be adequate to optimize cow performance. However, it is not possible under the actual state of knowledge to predict supplies of these vitamins for the animal according to the diet.

Full textAs the increase of photo induced skin cancers is a Public Health issue, it seemed important to review the efficacy of the different available photoprotective systems. Clothes constitute the simplest and the oldest mean of sun protection. However, the question of the photoprotection level arises. What is the photoprotective level of an adult wardrobe? Of a child one? How is a child protected during holidays, when he/she plays an outdoor sport, knowing that the solar exposure time will be several hours? We would Iike to answer these questions by measuring the photoprotective efficacy of clothes, using an in vitro method. , The in vivo process currently employed seems for us unethical. The method consists in irradiating the samples, then determining the percentage of transmitted radiation. It allows calculating an indicator of efficacy: the UV -Protection Factor (or UV-PF). UPF values obtained vary according to the type, color and thickness of the fabric. The inter est of superposition has been clearly demonstrated. The influence of washing on the level of photoprotection was assessed. The addition of UV filters in washing Iiquids does not seem relevant, meaning that the increase of the photoprotection measured with more UV filters is not higher than the data obtained when a cotton T-shirt is shrinked by washing. The environ mental impact of a massive use of those actives in detergents would be certainly considerable, but would not be associated with any additional benefits to humans. The study of glasses has also demonstrated that a broad photoprotective effect requires the association of different factors: an appropriate glass type, color and adequate thickness. The con cern of dermatologists is to recommend to their patients, particularly to young people, the best sunscreen, so we have sought to define what an "appropriate" sunscreen is. First of aIl, this is a cream where the value of determined SPF (Sun Protection Factor) is in adequacy with the value of claimed SPF. It turns out that ail branded creams do not meet this condition. Lndeed, we have demonstrated that bio-creams, containing only inorganic filters (Ti02 and/or ZnO), cannot achieve high levels of protection. Thus, an appropriate cream will be formulated with a mixture of organic and inorganic filters, covering the widest range of UV spectrum, and it will not contain ingredients such as alcohol. This work enabled us to quantify the efficacy of different photoprotective systems, which are complementary and must be used, as often as possible, together

Full textLes bactéries productrices d’exopolysaccharides (EPS) sont utilisées dans la fabrication du yogourt pour améliorer la viscosité, la texture et la rétention d’eau. Ces améliorations sont plutôt reliées aux propriétés intrinsèques des EPS et à leurs interactions avec les protéines qu'à leurs quantités. Dans plusieurs pays, les polysaccharides commerciaux (PS) sont autorisés comme agents stabilisants dans le yogourt. Les interactions EPS-PS peuvent aussi influencer positivement ou négativement les propriétés finales des yogourts. Malgré plusieurs études réalisées, la relation structure-fonction des EPS particulièrement dans les systèmes avec stabilisants a été peu étudiée et n’est pas entièrement comprise. Même les études portant sur le rôle de certaines propriétés intrinsèques des EPS ont été effectuées dans un système ne contenant que l'EPS. Les effets des EPS dans un système contenant des PS commerciaux sont encore non étudiés et donc inconnus. Ainsi, cette étude a été menée dans le but de mieux comprendre les effets de certaines propriétés intrinsèques des EPS produits in situ seuls ou en présence des PS commerciaux sur les propriétés rhéologiques, physiques et microstructurales du yogourt. Les résultats de cette étude ont montré que la charge négative de l'EPS ou PS contribue à l'amélioration de la fermeté et de la viscosité du yogourt mais augmente la synérèse. La rigidité, la linéarité et le poids moléculaire d'un EPS ou PS ont augmenté nettement la viscosité. Concernant la synérèse, les EPS ou PS neutres et rigides ont permis une très bonne amélioration de la capacité de rétention d'eau du yogourt par rapport au contrôle. Les résultats des PS utilisés avec la souche produisant un EPS anionique, rigide et linéaire n'ont pas montré d'effets majeurs sur la fermeté et la viscosité tandis qu’une diminution de la synérèse a été observée avec la pectine seulement. Une amélioration de la fermeté et de la viscosité a été observée lorsque les PS ont été utilisés avec les souches produisant des EPS neutres. L'amélioration de la viscosité était notamment plus importante avec les PS rigides. Les résultats de cette thèse ont rapporté, pour la première fois, des effets intéressants de certaines propriétés intrinsèques des EPS et/ou PS aussi bien dans la formation du gel laitier que sur les propriétés finales du yogourt. Ces résultats offrent aussi aux industriels et chercheurs laitiers des prémisses permettant de choisir les souches EPS+ et/ou PS afin de corriger ou améliorer une ou plusieurs propriétés spécifiques du yogourt.
Lactic acid bacteria (LAB) producing exopolysaccharides (EPS) are widely used in yogurt to improve viscosity, texture and water retention capacity. These improvements were shown to be related to the intrinsic properties of EPS and their interactions with proteins rather than to their concentration. Additionally, in many countries, commercial PS are used as stabilizers in yogurt. The co-presence of in situ-produced EPS and PS could also positively or negatively influence the properties of yogurt. Up to now, the structure-function relationship of EPS has not been widely studied and is still poorly understood. This context is more challenging since all studies on the role of some intrinsic properties of EPS have been carried out in systems containing only EPS. The effects of EPS in a system containing commercial PS are still unknown. In this context this study was performed to understand the effects of some intrinsic properties of EPS produced in situ by lactic acid bacteria used alone or in the presence of commercial PS on the rheological (gel formation, firmness and viscosity), physical (syneresis) and microstructural properties of yogurt. The results obtained in this study showed that the negative charge of the PS or EPS contributed to both yogurt firmness and viscosity improvements but increased syneresis. The backbone stiffness and linearity as well as the molecular weight of PS or EPS increased yogurt viscosity. Moreover, the neutral and stiff EPS or PS were able to improve yogurt water retention capacity as compared to control. The use of PS with an anionic, rigid and linear EPS producing strain, did not show major effects on both yogurt firmness and viscosity. However, only pectin was able to improve water retention capacity. The addition of PS to yogurt fermented by neutral EPS-producing strains improved viscosity and firmness. The highest viscosity values were obtained with stiff PS. Results of this thesis reported for the first time interesting effects of some EPS and/or PS intrinsic properties in both gel formation and final yogurt properties. Such results would also help dairy manufacturers and researchers to choose the suitable EPS+ strain/PS combination to correct or improve specific properties of yogurt.
