This invention relates to a pharmaceutical composition for parenteral or oral administration containing a radioactive compound which can be used diagnostically or therapeutically. The composition comprises a micro-emulsion constituted by a dispersion of vesicles or microsponges of a fatty acid based component in an aqueous or other pharmacologically acceptable carrier in which nitrous oxide is dissolved, the fatty acid based component comprising at least one long chain fatty acid based substance selected from the group consisting of free fatty acids and derivatives of free fatty acids, and the radioactive compound.

Pharmaceutical composition

A plant supporting formulation which is also suitable for use as a delivery vehicle, or a component of a delivery vehicle, for the delivery of one or more phytologically beneficial substances to a plant, and for enhancing the translocation of such delivered substance(s) in or on the plant, the formulation comprising a micro-emulsion constituted by a dispersion of vesicles or microsponges of a fatty acid based component in an aqueous carrier, the fatty acid based component comprising at least one long chain fatty acid based substance selected from the group consisting of free fatty acids and derivatives of free fatty acids. The dispersion is preferably characterized in that at least 50% of the vesicles or microsponges are of a diametrical size of between 50 nm and 5 micrometer. The dispersion is further also characterized in that the micro-emulsion has a zeta potential of between &#x2212;25 mV and &#x2212;60 mV.

Plant support formulation, vehicle for the delivery and translocation of phytologically beneficial substances and compositions containing same

This invention pertains to a method of preparing biological material from a biological sample selected from the group consisting of blood and sputum samples. The method includes the step of altering at least one constitutive characteristic of the biological sample in the presence of a capturing scaffold by adding a lysis buffer containing a solubilising agent and a detergent to the biological sample, for simultaneously inhibiting coagulation of the biological sample; lysing the biological sample to release the biological material from the biological sample, thus making the biological material available; and capturing at least one fraction of the biological material on the capturing scaffold.

Method of preparing biological material

The invention provides for a method of enhancing immunological responses to an antigen in a vaccine formulation, and for a vaccine formulation that provides for an enhanced immunological response to an antigen. In the method and formulation the antigen is administered with an adjuvant which adjuvant comprises a solution of nitrous oxide gas in a pharmaceutically acceptable carrier solvent for the gas and which adjuvant includes at least one fatty acid or ester or other suitable derivative thereof selected from the group consisting of oleic acid, linoleic acid, alpha-linolenic acid, gamma-linolenic acid, arachidonic acid, eicosapentaenoic acid [C20: 5&#x3c9;3], decosahexaenoic acid [C22: 6&#x3c9;3], ricinoleic acid and derivatives thereof selected from the group consisting of the C1 to C6 alkyl esters thereof, the glycerol-polyethylene glycol esters thereof and the reaction product of hydrogenated natural oils composed largely of ricinoleic acid based oils, such as castor oil with ethylene oxide.
