Temperature-sensitive liposomal formulation |
April 27, 2004 |
| A liposome contains an active agent and has a gel-phase lipid bilayer membrane comprising phospholipid and a surface active agent. The phospholipids are the primary lipid source for the lipid bilayer membrane and the surface active agent is contained in the bilayer membrane in an amo |

Liposomes containing active agents |
October 2, 2001 |
| Liposomes formulations are designed to maximize the amount of poorly water-soluble active agent that can be carried by the liposome. Liposomes containing active agent in the lipid bilayer of the liposome, and/or entrapped within the liposome interior space in a micellar preparation are |

Methods for producing gas microbubbles having lipid-containing shells formed thereon |
April 3, 2001 |
| A method for producing a gas microbubble comprises subjecting the gas microbubble to isothermal conditions or cooling conditions such that the lipid-containing shell cools at a rate ranging from about 10.sup.0.degree. C./min. to about 10.sup.3.degree. C./min., and wherein said subjecting |

Temperature-sensitive liposomal formulation |
March 13, 2001 |
| Temperature sensitive liposomes containing active agents are described. The liposomes comprise phospholipids and a surface active agent, such as a lysolipid, that increases the amount of active agent released by the liposome at the phase transition temperature of the liposome. Such l |

Liposomes containing active agents |
November 7, 2000 |
| Liposomes formulations are designed to maximize the amount of poorly water-soluble active agent that can be carried by the liposome. Liposomes containing active agent in the lipid bilayer of the liposome, and/or entrapped within the liposome interior space in a micellar preparation are |

Liposomes containing active agents aggregated with lipid surfactants |
March 16, 1999 |
| Liposomes contain active agents which are aggregated with a lipid surfactant. The composition of the liposome membrane stabilizes the membrane against the disruptive effects of the active agent-surfactant aggregate contained therein. |

Liposomes containing active agents aggregated with lipid surfactants |
October 27, 1998 |
| Liposomes contain active agents which are aggregated with a lipid surfactant. The composition of the liposome membrane stabilizes the membrane against the disruptive effects of the active agent-surfactant aggregate contained therein. |
