摘要： A target-specific image-enhancing agent for medical imaging comprises an extended poly(amino acid), wherein at least 90 percent of the amino acid residues are conjugated to signal-generating moieties attached to signal-controlling moieties via bonds that are cleavable by a physiological substance produced by the target. The image-enhancing agent becomes activated when the bonds is cleaved by the physiological substance. The image-enhancing agent is used in detecting and/or diagnosing a disease that is characterized by an overproduction of the substance.

摘要： This invention pertains to a method of production of 4-hydroxybenzoic acid, with purification and recovery of 4-hydroxybenzoic acid directly from the fermentation medium of a cultured organism, in the presence of other chemical species. Ion exchange resin is used during the fermentation process to recover the chemical product without the necessity of separating the biomass from the fermentation supernatant by filtration after fermentation is complete and then treating the filtrate to recover the product. This reduces or eliminates the need for filtration steps and eliminates the need for energy-intensive water removal processes. Furthermore, the removal of the product during the fermentation dramatically increases the production of the product during the fermentation process. This method therefore can both increase the amount of product produced in a single fermentation run and reduce the per unit cost of its biocatalytic production.
摘要翻译： 本发明涉及一种生产4-羟基苯甲酸的方法，在其它化学物质存在下，直接从培养的生物体的发酵培养基中纯化和回收4-羟基苯甲酸。 在发酵过程中使用离子交换树脂来回收化学产品，而不需要在发酵完成后通过过滤从发酵上清液分离生物质，然后处理滤液以回收产物。 这减少或消除了对过滤步骤的需要，并且消除了对能量密集型除水过程的需要。 此外，在发酵期间除去产物显着增加了发酵过程中产物的产生。 因此，该方法可以增加在单次发酵运行中产生的产物的量并降低其生物催化生产的单位成本。
