The invention provides hops extracts or derivatives thereof for use in treating a patient prophylactically andor therapeutically for ulcerogenic-type disorders of the stomach andor intestines. Method, device, and computer-readable medium embodiments generate a user interface image, separate the user interface image into a plurality of sub-images, convey the plurality of sub-images to remote terminals, and configured to receive input data from the remote terminals. At least a portion of the second ends of the non-transparent cables emit light from the light emitting diodes. The dosage form may be used to treat gastrointestinal disorders, such as irritable bowel syndrome. The injection of current by the offset cancellation circuit can reduce or eliminate an offset voltage, while the cascode stage can prevent parasitic capacitance associated with the offset cancellation circuit from creating further mismatch.
