Abstract: The present invention provides methods for producing recombinant peptides in a bacterial host utilizing a mannitol, arabitol, glucitol, or glycerol-inducible promoter, wherein the host bacterial cell that produces the peptide has been rendered incapable of degrading or metabolizing mannitol, arabitol, or glucitol, or derivatives or analogues thereof. The present invention provides bacterial cells that have been genetically altered to inhibit the metabolism or degradation of mannitol, glucitol, or arabitol, or derivatives or analogues thereof. The present invention utilizes mannitol, arabitol, glucitol, or glycerol to induce expression of a target polypeptide from an inducible promoter, allowing for the use of an inexpensive and stable carbon source inducer in the fermentation processes for the production of recombinant peptides.

Abstract: A medical apparatus (10) for detecting a predetermined component of breath and producing a breath-component signal over a measurement time. Such breath-component signal may be related to a fat metabolism indicator.

Abstract: A device useful for oral drug delivery device consisting of: (a) a capsule, tablet or pill designed to disperse in the gastrointestinal system; (b) an RFID tag positioned in the capsule, tablet or pill, the RFID tag comprising an antenna; (c) an object selected from the group consisting of a magnet, a ferromagnetic object, a ferrite object and an electromagnetic shielding object positioned within, over or adjacent the antenna of the RFID tag to alter the antenna characteristics of the RFID tag so that if the RFID tag is interrogated before the capsule, tablet or pill disperses in the gastrointestinal system, the response of the RFID tag is sufficiently altered or attenuated to determine that the capsule, tablet or pill has not dispersed in the gastrointestinal system and so that if the RFID tag is interrogated after the capsule, tablet or pill has dispersed in the gastrointestinal system, the object separates from the RFID tag so that the response of the RFID tag is sufficiently detectable to determine that t

Abstract: Described are enzyme systems specific for acetone and methods of using these enzyme systems to detect acetone in biological or environmental samples. Biosensors containing these enzyme systems are disclosed, in which detection of acetone may be achieved by linking electrochemical, photometric, or other detection means to one or more acetone-specific enzyme reactions or pathways. Methods of using such acetone-specific biosensors include subject management of weight loss, disease detection, and bioavailability monitoring of therapeutics.
