Abstract: A porous structure sealed at both ends for use in a gas separation module; and a method for separating components of a gas stream.

Abstract: A method and system are provided for entering input into a computing system. The method involves detecting one or multiple input movements using a sensing panel associated with the computing system and classifying each detected input movement as being of a particular type. Each detected input movement is translated to an instruction signal by consulting a knowledge database. The instruction signals are transmitted to the computing system for execution. Translation of a detected input movement to an instruction signal involves a main process and one or more sub-processes, wherein each sub process is invoked by the main process in response to a particular type of detected input movement.

Abstract: Three pairs of C-2 epimeric xanthones isolated from Garcinia hanburyi and method for efficiently separating the xanthone compounds into individual epimers, each of which possesses varying biological effects. The compounds are useful for their anticancer effects, particularly because they are shown to be non-substrates of the multidrug-resistance transporter. Some of the epimers have significant inhibitory effects on cytochrome P450 systems. The xanthone compounds of the present invention are gambogic acid, epigambogic acid, isogambogic acid, isoepigambogic acid, 30-hydroxygambogic acid and 30-hydroxyepigambogic acid.

Abstract: Two novel benzofuran glycosides, named psoralenoide and isopsoralenoide, isolated and purified from the seeds of Psoralea corylifolia. The compounds are useful as therapeutic agents for diseases defined under TCM and as a more accurately means of quality control and assessment for Psoralea corylifolia, an important herbs used in TCM.
