  • Chromatographie Liquide Haute Pression: Techniques de chromatographie liquide basée sur des pressions d'injection élevées, une sensibilité élevée, et une grande vitesse.
  • Acide Nitreux: Acide nitreux (HNO2). C'est un acide faible qui existe seulement en solution. Il peut former des nitrites hydrosolubles et des esters stables. (de l'index de Merck, du 11ème ED)
  • Cellules Caco-2: Human colonic ADENOCARCINOMA cells that are able to express differentiation features characteristic of mature intestinal cells, such as ENTEROCYTES. These cells are valuable in vitro tools for studies related to intestinal cell function and differentiation.
  • Biodisponibilité: Vitesse et intensité auxquelles le principe actif d'une forme galénique devient disponible sur le site d'action du médicament ou dans un milieu biologique pouvant être perçu comme reflétant l'accessibilité à un site d'action..
  • Hétérosides: Any compound that contains a constituent sugar, in which the hydroxyl group attached to the first carbon is substituted by an alcoholic, phenolic, or other group. They are named specifically for the sugar contained, such as glucoside (glucose), pentoside (pentose), fructoside (fructose), etc. Upon hydrolysis, a sugar and nonsugar component (aglycone) are formed. (From Dorland, 28th ed; From Miall's Dictionary of Chemistry, 5th ed)

  • Structure Moléculaire: The location of the atoms, groups or ions relative to one another in a molecule, as well as the number, type and location of covalent bonds.
  • Loranthaceae: The showy mistletoe plant family of the order Santalales, subclass Rosidae, class Magnoliopsida. This includes parasitic tropical plants with haustoria connecting to the hosts. The leaves are opposite and thick. The flowers (4-7) have both calyx and corolla. The fruit is a berry with one seed.
  • Flavanones: A group of FLAVONOIDS characterized with a 4-ketone.
  • Vaccinium Myrtillus: A plant species of the family VACCINIUM.
  • Ginkgo Biloba: Unique espèce du genre Ginkgo, de la famille des Ginkgoacées. C'est la source d'extraits d'intérêt médicinal, particulièrement l'Egb 761. Le terme Ginkgo peut référer au genre ou à l'espèce.
  • Oxydoréduction: Réaction chimique au cours de laquelle un électron est transféré d'une molécule à une autre. La molécule ayant donné l'électron est appelée l'agent réducteur ou réducteur, alors que la molécule ayant capté l'électron est appelée agent oxydant ou oxydant. Agents réducteurs et agents oxydants fonctionnent par couples (oxydant/réducteur ou couple rédox).
  • Phytothérapie: Utilisation de plantes ou d'herbes pour soigner des maladies ou pour atténuer la douleur.
  • Feuilles Plante: Structures étendues, d
  • Vitis: A plant genus in the family VITACEAE, order Rhamnales, subclass Rosidae. It is a woody vine cultivated worldwide. It is best known for grapes, the edible fruit and used to make WINE and raisins.
  • Absorption Intestinale: Uptake of substances through the lining of the INTESTINES.
  • Cellules Cancéreuses En Culture: Cells grown in vitro from neoplastic tissue. If they can be established as a TUMOR CELL LINE, they can be propagated in cell culture indefinitely.
  • Fruits: The fleshy or dry ripened ovary of a plant, enclosing the seed or seeds.
  • Rats: The common name for the genus Rattus.
  • Adulte: A person having attained full growth or maturity. Adults are of 19 through 44 years of age.
  • Lignée Cellulaire: Established cell cultures that have the potential to propagate indefinitely.
  • Microscopie : Microscopy using an electron beam, instead of light, to visualize the sample, thereby allowing much greater magnification. The interactions of ELECTRONS with specimens are used to provide information about the fine structure of that specimen. In TRANSMISSION ELECTRON MICROSCOPY the reactions of the electrons that are transmitted through the specimen are imaged. In SCANNING ELECTRON MICROSCOPY an electron beam falls at a non-normal angle on the specimen and the image is derived from the reactions occurring above the plane of the specimen.
  • Test Comète: A genotoxicological technique for measuring DNA damage in an individual cell using single-cell gel electrophoresis. Cell DNA fragments assume a "comet with tail" formation on electrophoresis and are detected with an image analysis system. Alkaline assay conditions facilitate sensitive detection of single-strand damage.
