Bromure de zincZinc bromide (ZnBr2) is an inorganic compound with the chemical formula ZnBr2. It is a colourless salt that shares many properties with zinc chloride (ZnCl2), namely a high solubility in water forming acidic solutions, and good solubility in organic solvents. It is hygroscopic and forms a dihydrate ZnBr2·2H2O. ZnBr2 · 2H2O is prepared by treating zinc oxide or zinc metal with hydrobromic acid. ZnO + 2 HBr + H2O → ZnBr2·2H2O Zn + 2 HBr → ZnBr2 + H2 The anhydrous material can be produced by dehydration of the dihydrate with hot CO2 or by reaction of zinc metal and bromine.
Major prion protein'Major prion protein' (PrP) is encoded in the human body by the PRNP gene also known as CD230 (cluster of differentiation 230). Expression of the protein is most predominant in the nervous system but occurs in many other tissues throughout the body. The protein can exist in multiple isoforms: the normal PrPC form, and the protease-resistant form designated PrPRes such as the disease-causing PrPSc(scrapie) and an isoform located in mitochondria.
GlycémieLa glycémie est la concentration (par extension, le taux) de glucose dans le sang, ou le plus souvent dans le plasma sanguin. Elle est mesurée en général en millimoles de glucose par litre de sang, rarement en milligrammes de glucose par décilitre de sang, ou encore en grammes de glucose par litre de sang. La régulation de la glycémie est un système de régulation complexe, mettant en œuvre des hormones (dont les deux principaux antagonistes insuline, hypoglycémiante, et glucagon, hyperglycémiant) ainsi que divers organes (pancréas, foie, rein).
Biomarker (medicine)In medicine, a biomarker is a measurable indicator of the severity or presence of some disease state. It may be defined as a "cellular, biochemical or molecular alteration in cells, tissues or fluids that can be measured and evaluated to indicate normal biological processes, pathogenic processes, or pharmacological responses to a therapeutic intervention." More generally a biomarker is anything that can be used as an indicator of a particular disease state or some other physiological state of an organism.
