Abstract: A system and method to control the cleaning and emptying of a wastewater holding tank on a Recreational Vehicle. The system has the ability to autonomously open the drain valve allowing the tank to be emptied while connected to a suitable drain hose. It also has the ability to automatically rinse the tank from an external water source—should the system be so equipped. Further, the system and method can operate a wastewater system with two or more tanks each tank having its own gate valve used to empty the tank. In, this configuration the system will only open one gate valve at a time.

Abstract: The present invention concerns nanoparticle formulations suitable for the delivery of one or more therapeutic agents, the formulations comprising: a cationic cholesterol derivative; a neutral phospholipid; cholesterol or a neutral cholesterol derivative; and a saturated fatty acid, PEGylated neutral derivative of phosphatidylethanolamine or phosphatidylcholine.

Abstract: The present invention provides novel liposomes comprising Gd.DOTA.DSA (gadolinium (III) 2-{4,7-bis-carboxymethyl-10-[(N,N-distearylamidomethyl-N?-amido-methyl]-1,4,7,10-tetra-azacyclododec-1-yl}-acetic acid), characterised in that said liposome further comprises a neutral, fully saturated phospholipid component (e.g. DSPC (1,2-distearoyl-sn-glycero-3-phospocholine]), which are of particular use in the preparation of magnetic resonance contrast agents for enhancing a magnetic resonance image of tumours in a mammal.
