La phase minérale de l'os est assimilable à une apatite carbonatée mal cristallisée. Le vieillissement de la population conduit les praticiens à avoir recours à des substituts osseux de synthèse. Parmi ces biomatériaux, on peut distinguer les phosphates de calcium biphasés (BCP) en hydroxyapatite (HA) et en phosphate tricalcique (β-TCP). Dans un premier temps, nous avons mis en évidence, à l'aide de la RMN du solide du 31P et de la DRX, l'incorporation du sodium au sein de la maille du β-TCP, sa localisation ainsi que son influence sur les paramètres de maille.

Abstract:
The cyclic nature of the beef industry is dependent on the supply and demand transaction initiated by consumers’ acceptability of quality meat products. When purchasing beef at the grocery store, consumers are dependent on USDA grades and visual appraisal; consumers expect consistency in products. Upon this appraisal, quality is determined by the color, marbling content, and texture of a particular retail cut, as well as cooked characteristics of tenderness, flavor, and juiciness. Variability in meat tenderness is a major quality defect of beef (Morgan et al., 1991b; Smith et al., 1992). A com

The thesis investigates pipeline plugging mechanisms that have occurred during interim stabilization transfers at Hanford. A laboratory-scale saltwell pumping test loop was designed to evaluate a surrogate of Hanford Tank 241-SX-104 supernate. The effect of surrogate flow rate, cooling water flow rate and phosphate concentrations on plugging mechanisms was investigated. Critical parameters like particle and agglomerate size, velocity and bed growth rate were determined. Theoretical models were used to compare the experimental pressure rise and temperature drop of the surrogate in the channel.

Abstract:
Phosphate plays a critical role in the body as a constituent of bone and tooth for body development, and as a urinary buffer for pH in body acid-base balance regulation. The phosphorus level in blood in human is between 3.0 to 4.5 mg/dl. When the blood phosphate concentration is lower than 2.5 mg/dl, the person develops hypophosphatemia. When the blood phosphate concentration is higher than 4.5 mg/dl, the person develops hyperphosphatemia.

Inorganic phosphate (Pi) homeostasis is mainly regulated by absorption of dietary Pi in the small intestine and reabsorption of filtered Pi in the kidney. I have characterized the 5 '-flanking region and overall gene structure of the murine type IIb sodium-phosphate cotransporter (Na/Pi-IIb), a major apical Pi transporter. The Na/Pi-IIb cotransporter gene spans more than 18 kb and consists of 12 introns and 13 exons. Three promoter/reporter gene constructs, -159/+73, -429/+73 and -954/+73, showed significant luciferase activity when transfected into in rat intestinal epithelial (RIE-1) cells.

The combined actions of various inorganic phosphate ion (Pi) regulators in bone, intestine and kidney are crucial for overall Pi homeostasis. Regulation of Pi levels is mediated by the activity of various sodium-phosphate (Na-Pi) co-transporters. Among the three families of Na-Pi co-transporters, Type-III transporters (PiT1 and PiT2) are ubiquitously expressed, but these are the sole functional Pi-transporters in osteoblasts, thus implicating them in the regulation of bone mineralization where very high Pi levels are required for apatitic (calcium-phosphate) mineral deposition in the extrace

Abstract:
T cell protein tyrosine phosphatase (TC-PTP / PTPN2) is an enzyme that is essential for the proper functioning of the immune system and that participates in the control of cell proliferation, and inflammation. We previously observed that TC-PTP-/- mice display various immunodeficiencies, hypersensitivity to lipopolysaccharide (LPS) and die within three weeks of birth due to anemia and widespread inflammation. A recent analysis of the Wellcome Trust Case Control Consortium (WTCC) genome wide scan data, reported in 2007, indicated a potential role for TC-PTP in inflammatory bowel disease (IBD).

Abstract:
In Asia skin lightening products have grown to be the best selling skin care products, whereas in the Western hemisphere, including Europe and North America, the main demand is for the treatment of age spots and skin even toning. For African and Asian women, skin lightening is part of their culture, as lighter skin signifies increased wealth and social status. It is believed that blending vitamin C, or its derivates, with kojic acid, or its esters, could synergistically inhibit melanin synthesis. Kojic acid dipalmitate was chosen over kojic acid, as better product stability is ensured without

Les resultats presentes dans ce travail interessent les mecanismes de la regulation intrinseque, endocrine et autocrine ou paracrine du cotransport na/pi. La premiere partie des resultats a ete obtenue dans des cellules tubulaires proximales de lapin en culture primaire: la sphingomyelinase diminue le contenu membranaire en sphingomyeline et en cholesterol et inhibe les cotransports na-glucose et na-pi ; la repletion des cellules en cholesterol obtenue par des liposomes ne corrige que la baisse d'activite du na-glucose. La sphingosine exogene inhibe l'effet de la pkc sur les cotransports mais

Abstract:
La patuline constitue un contaminant chimique toxique fréquemment rencontré dans les produits issus de la transformation des fruits, notamment des pommes. Cette toxine essentiellement produite par Penicillium expansum et Byssochlamys nivea fait l'objet d'une réglementation européenne récente (N°1425/2003). Contrairement à certaines mycotoxines règlementées telles que les aflatoxines, les trichothécènes ou les fumonisines, la génétique de la voie de biosynthèse de la patuline est fort mal connue, bien que cette voie ait été relativement bien caractérisée du point de vue chimique.

Ce travail s’inscrit dans le cadre d’une étude systématique des propriétés physico-chimiques de polyphosphates à l’argent permettant d’avancer sur de nouvelles voies pour les dispositifs tels que l’éclairage, les lasers accordables dans le visible, la radiophotoluminescence. L'objectif de ce travail vise la compréhension des mécanismes de luminescence de l’ion Ag+ dans les composés Na1-xAgxLn(PO3)4 (Ln = La et Y) dont la structure a été parfaitement déterminée. La luminescence des monocristaux provient des ions Ag+, dans des sites isolés et proches de lacunes positives (Ag2+) résultant de la p
