Abstract: The invention provides a novel polymer platform to deliver a desired combination of therapeutic agents to a site in need thereof for the treatment of cancer. In certain embodiments the platform is a modular polymer platform that allows for customization based upon the tumor of the subject to be treated.

Abstract: A packing box of wet wipes, which includes a body and a cover connected to the body. The cover includes: a cover body having a press button mounted therein, a top lid having a fastening part mounted thereon and mated with the press button, and a resilient connection part having a first end secured to a side of the top lid opposite to the fastening part and a second end protruding through a through hole of the top lid and secured to the cover body. The packing box of wet wipes of present invention has a simple structure, and can be used repeatedly and easy to open.

Abstract: The present invention provides novel nitrones, their preparation and use. The novel compounds have the following formula: I The compounds of the present invention have strong antioxidative activity, and are thrombolytic. These compounds can be used to treat and/or prevent diseases caused by overproduction of free radicals and/or formation of thrombus.

Abstract: Distributed valve simulated moving beds are described in which junctions located between successive columns interrupt the flow of process fluid between columns, and either transmit the process fluid through a zone bypass to a succeeding column within the same zone or, if the junction is located between zones, direct the process fluid to an input/output line that is dedicated to the particular zone that immediately follows the junction. At each step of the SMB's operation, the distribution of flows in each junction is modulated to accomplish movement of ports consistent with the SMB's design. Further described are simulated moving beds that contain one or more decoupled on-line regeneration zones. The regeneration zone is decoupled from the separation zones in the sense that it observes a step time (a “regeneration interval”) that is different than the step time observed by the separation zones of the SMB.

Abstract: The present invention comprises the optimization of a four zone simulated moving bed system configured to separate a first component from a mixture containing the first component and a second component wherein the first component exhibits non-linear adsorption and non-negligible mass transfer resistances. In one example, the four zone simulated moving bed is optimized to separate Clarithromycin from a mixture containing Clarithromycin and 6,11-O-methyl erythromycin A. The present invention further comprises a four zone or a five zone apparatus having a first portion and a second portion and the optimization of the four zone or five zone apparatus to separate a first component from a mixture containing the first component and a second component and the method of using the same. In one example, the four zone and five zone simulated moving beds are optimized to separate Clarithromycin from a mixture containing Clarithromycin and 6,11-O-methyl erythromycin A.

Abstract: Simulated moving beds for the chromatographic purification of insulin are provided. The insulin can be resolved from one or more components, using one or more simulated moving bed rings. Methods for designing simulated moving beds for the purification of insulin, and optimizing the operating parameters of the simulated moving beds, are also provided based upon the standing wave design.

Abstract: Herbs are dried by applying microwave power to herbs in a chamber under reduced or negative pressure to reduce the moisture content of the herbs without significantly damaging the flavor of the dried herbs and produce a dried herb having a flavor more closely approaching the flavor of fresh herbs than dried herbs produced by conventional processes.
