    Abstract: Compositions having a texaphyrin-lipophilic molecule conjugate loaded into a biological vesicle and methods for imaging, diagnosis and treatment using the loaded vesicle are provided. For example, liposomes or red blood cells loaded with a paramagnetic texaphyrin-lipophilic molecule conjugate have utility as a blood pool contrast agent, facilitating the enhancement of normal tissues, magnetic resonance angiography, and marking areas of damaged endothelium by their egress through fenestrations or damaged portions of the blood vascular system. Liposomes or cells loaded with a photosensitive texaphyrin-lipophilic molecule conjugate can be photolysed, allowing for a photodynamic therapy effect at the site of lysis. Availability of red blood cells loaded with a photosensitive texaphyrin-lipophilic molecule conjugate provides a method for delivering a photodynamic therapeutic agent to a desired site with a high concentration of oxygen. By presenting the agent in this way, it is expected that a patient will experience less toxicity.

    Abstract: This invention relates to a process for the production of cyclohexanone oxime by reacting cyclohexanone with excess aqueous hydroxylamine in the presence of excess ammonia. More specifically, the invention relates to improving yields of the oxime while reducing undesirable by-product formation by use of two or more stages of reaction with correlated adjustment of reaction conditions in each stage. The invention also involves improved recovery of the unreacted hydroxylamine reactant for recycle in the process.
