    Abstract: Methods and formulations for improving efficacy of chemotherapeutic treatment. The formulation includes at least one chemotherapeutic agent and at least one phospholipid or a material comprising the same. The phospholipid facilitates entry of the at least one chemotherapeutic agent into cells of an afflicted individual. A sufficient dosage of a blood-thinning agent is optionally included to mitigate risk of developing blood clots attributable to administration of the chemotherapeutic agent(s). The chemotherapeutic agent(s) and the phospholipid(s), or the material containing the phospholipid(s), are administered in any order but in sufficient time proximity to one another such that the effect of the phospholipid(s) of facilitating entry of the chemotherapeutic agent(s) into the cells at least partially overlaps with the therapeutic effect of the chemotherapeutic agent(s).

  • Patent number: 7847033
    Abstract: An emulsifier for use in forming a film for a suspended particle device (SPD) wherein the film is comprised of a cross-linked matrix polymer having a plurality of droplets of a liquid light valve suspension distributed therein.

A first one of the segments is soluble in an uncured liquid matrix polymer used in forming the film, but insoluble in a liquid suspension medium of which the droplets are dispersed. A second segment is soluble in the liquid suspending medium in the droplets and insoluble in the uncured liquid matrix polymer. The first and second segments have substantially the same index of refraction and the index of refraction of the segments is within 0.010 of that of each phase of an emulsion formed with the emulsifier.
