Abstract: The invention relates to a device and a method for quantifying a variation of oxygenation in a tissue by using a magnetic resonance imaging technique. The variation of oxygenation in a tissue can be quantified from a measured variation of a proton longitudinal relaxation rate ?R1 and from calibration data. The method of the invention is characterized in that the variation of proton longitudinal relaxation rate ?R1 that is used is a variation of proton longitudinal relaxation rate of lipids rather than a variation of proton longitudinal relaxation rate of water molecules.

Abstract: Provided are compositions comprising (a) a propylene-alpha-olefin copolymer comprising at least about 50%, by weight of the propylene-alpha-olefin copolymer, of propylene-derived units and about 5% to about 35%, by weight of the propylene-alpha-olefin copolymer, of units derived from at least one of ethylene or a C4-10 alpha-olefin, wherein the polypropylene-alpha-olefin copolymer has a heat of fusion of about 75 J/g or less, melting point of about 100° C. or less, and crystallinity of about 2% to about 65% of isotactic polypropylene; and (b) a pesticide, preferably a pyrethroid; films, filaments, fibers, sheets, molded objects, extruded articles, woven or non-woven materials, yarns, or mosquito nets made therefrom; and methods of their manufacture.
