Publication number: 20240131062Abstract: The spray dried plasma by the nature of its characteristics and the process by which it is made allows for a dried plasma with reduced pathogens. It has at least three aspects of pathogen reduction that results in a plasma product with reduced or no pathogens. The first aspect relates to a spray drying disposable and machine that eliminates or minimizes the introduction of pathogens into the spray drying process and is referred to as the anti-contamination process. The second aspect of pathogen reduction relates to the spray drying process and parameters that reduces pathogens that may be present in the donor plasma, and/or inhibit pathogen growth and/or pathogen proliferation introduced by the donor plasma. The third aspect results in reduced pathogens occurring during storage of the dried plasma wherein the manufacturing and storage conditions are such that pathogens are reduced, and/or pathogen growth and/or pathogen proliferation are inhibited.Type: ApplicationFiled: September 14, 2023Publication date: April 25, 2024Applicant: Velico Medical, Inc.Inventors: Mark A.

Publication number: 20220213298Abstract: Porous cellulose microparticles and their use in, inter alias, cosmetic and pharmaceutic preparations are provided. These microparticles comprise cellulose I nanocrystals aggregated together, thus forming the microparticles, and arranged around cavities in the microparticles, thus defining pores in the microparticles. A method of for producing these microparticles is also provided. It involves mixing a suspension of cellulose I nanocrystals with an emulsion of a porogen to produce a mixture comprising a continuous liquid phase in which droplets of the porogen are dispersed and in which the nanocrystals of cellulose I are suspended; spray-drying the mixture to produce microparticles; and if the porogen has not sufficiently evaporated during spray-drying to form pores in the microparticles, evaporating the porogen or leaching the porogen out of the microparticles to form pores in the microparticles.Type: ApplicationFiled: May 6, 2020Publication date: July 7, 2022Inventors: Mark P.

Patent number: 6054253Abstract: The process for fabricating a ridge waveguide on a substrate uses a photosensitive sol-gel glass material prepared, according to a first embodiment, by mixing methacryloxypropyltrimethoxysilane (H.sub.2 C.dbd.C(CH.sub.3)CO.sub.2 (CH.sub.2).sub.3 Si(OCH.sub.3).sub.3) and methacrylic acid (H.sub.2 C.dbd.C(CH.sub.3)COOH) or, according to a second embodiment, by mixing methacryloxypropyltrimethoxysilane (H.sub.2 C.dbd.C(CH.sub.3)CO.sub.2 (CH.sub.2).sub.3 Si(OCH.sub.3).sub.3) with bis(s-butoxy)aluminoxytriethoxysilane. A thick film of photosensitive sol-gel glass material is first dip coated on at least a portion of the substrate. A photomask is applied to the film of photosensitive sol-gel glass material, and this sol-gel material is exposed to ultraviolet radiation through the opening(s) of the photomask to render a portion of the film insoluble to a given solvent and thereby imprint the ridge waveguide in that film.Type: GrantFiled: October 10, 1997Date of Patent: April 25, 2000Assignee: McGill University-The Royal Institute for the Advancement of LearningInventors: M.

Patent number: 4569924Abstract: Carbon-metal catalysts having a substantial amount of catalytically active metal, e.g. silver, deposited thereon in zero-valent, small cluster form, are prepared by vaporizing the metal under low vapor pressure conditions in the vicinity of an organic liquid solvent e.g. tetrahydrofuran, such that the metal dissolves in the solvent as a labile solvated zero-valent metal complex. This complex is contacted with the carbon so that the complex diffuses onto the surface of the carbon and also into the pores thereof.Type: GrantFiled: November 30, 1983Date of Patent: February 11, 1986Inventors: Geoffrey A.
