摘要:
Disclosed and claimed are: a composition including at least one glycosaminoglycan, e.g., CIS, at least one perfluorinated substance and at least one alginate, e.g., sodium alginate, wherein: the at least one glycosaminoglycan and/or the perfluorinated substance and/or the alginate are cross-linked or polymerized, e.g., the alginate is cross-linked or polymerized, for instance by addition of an inorganic salt, such as a calcium salt; or the at least one glycosaminoglycan, the perfluorinated substance and the alginate are covalently bound, e.g., by means of a coupling reaction involving a linker molecule such as DVS; or the at least one glycosaminoglycan and/or the perfluorinated substance and/or the alginate are cross-linked or polymerized, e.g., the alginate is cross-linked or polymerized, for instance by addition of an inorganic salt, such as a calcium salt, and the at least one glycosaminoglycan and the alginate are covalently bound, e.g., by means of a coupling reaction involving a linker molecule such as DVS, and the covalent binding can have been performed prior to cross-linking or polymerizing or vice versa; and, gels comprising the composition; mixtures of such gels or of at least one such gel and at least one such composition; and, methods for making and using such compositions and gels, including products therefrom such as “paints”, sprays, matrices, beads, microcapsules.
摘要:
A stable liquid nanoemulsion of a volatile gas anesthetic, such as, isoflurane or sevoflurane, is disclosed which is effective in inducing and maintaining a state of anesthesia and/or general anesthesia in a patent. A method of preparation of stable liquid formulations of volatile gas anesthetics is presented, as well as a method for directly testing the concentration of a volatile gas anesthetic in a stable liquid formulation. A kit comprising an amount of a stable liquid formulation of a volatile gas anesthetic, and the non-specialized equipment for administration of the same to a patient, either in an operating room environment or in the field, is also described herein.
摘要:
Provided is a cell culture apparatus for culturing cells, that provides enhanced oxygen delivery and supply to cells without the need for stirring or sparging. Oxygen diffusion occurs on both sides of the culture vessel, top and bottom. A gas-permeable membrane that includes perfluorocarbons in its composition allows for the rapid, enhanced and uniform transfer of oxygen between the environment of cells or tissues contained in the cell culture container apparatus and the atmosphere of the incubator in which the cell culture apparatus is incubated.
