摘要: A method of stably encapsulating a weak acid drug in liposomes, at a high concentration, is disclosed. The method employs a proton shuttle mechanism involving the salt of a weak acid to generate a higher inside/lower outside pH gradient. The weak acid compound accumulates in liposomes in response to this gradient, and may be retained in the liposomes by cation-promoted precipitation or low permeability across the liposome transmembrane barrier. Also disclosed is a reagent combination for practicing the method, and a liposome composition formed by the method.

摘要: Fixing system adapted to be fixed in a removable manner on a penetrable surface, said fixing system comprising a housing base part and a pair of pin blocks mounted in the housing. Each pin block comprises a rigid body portion and a plurality of pins inclined obliquely in relation to said body portion. The pins of one pin block are oriented in a direction opposed to the direction of the pins of the other pin block, whereby an actuator mechanism moves the pin blocks apart or together, from a disengaged position to an engaged and stable position.
