Abstract: Various embodiments are described herein for a device and method for an ingestible medical device with a rotatable element. In some described embodiments, the ingestible medical device includes a storage sub-unit with multiple chambers each having an opening for collecting or dispensing substances from the GI tract. The device further comprises a chamber enclosure with an access port. One of the chamber enclosure and the storage sub-unit are rotatable to allow for aligning the access port with a chamber opening. The ingestible medical device includes a sensor for positioning the access port of the chamber enclosure or the storage sub-unit as one of these elements rotates.

Abstract: The invention relates to immobilized or encapsulated enzyme and/or cells to lower bile acids and cholesterol. The invention also relates to methods of quantitatively measuring bile acids. The invention provides a composition for decreasing the amount of a target compound in the gastrointestinal tract of an animal, comprising: a) a biologically active agent which decreases the amount of the target compound; b) a retainer for retaining the biologically active agent by contacting the agent to limit movement of the agent; and c) a carrier.

Abstract: The present disclosure provides a device having a casing with a barrier surface and a contact surface and a composition in the casing having a nitric oxide precursor and an isolated enzyme or live cell expressing an endogenous enzyme, for converting the nitric oxide gas precursor to nitric oxide gas or having activity on a substrate that produces a catalyst that causes the conversion of the nitric oxide gas precursor to nitric oxide gas. The present disclosure also provides compositions, methods and uses for skin cosmesis.
