Abstract: A system and method for artificial intelligence (AI)-assisted medical diagnostics. A real-time endoscopic ultrasound (EUS) video stream of a patient's organ, such as the pancreas, is received at a computing device. The EUS video stream comprises a plurality of imaging modalities, including at least grey-scale data and elastography data representing tissue stiffness. One or more processors execute an AI model, which processes the video stream to identify, segment, and characterize a region of interest. A visual output is generated for display on a user interface in real-time, the output comprising the EUS video stream with a graphical overlay that includes a visual indicator delineating the segmented region and a classification label corresponding to the characterization, thereby providing real-time clinical decision support.

Abstract: A polyurethane polymer includes at least one buffer selected to adjust pH to a pH within a desired range. The buffer compound is immobilized within the polymer, and the polymer has a buffer capacity in excess of 3 micromoles of acid or base per gram polymer. A polymer includes at least one enzyme that is selected to catalyze a reaction of a substance. The enzyme is immobilized within the polymer. The polymer also includes at least one buffer selected to adjust the pH in the vicinity of the enzyme to a pH within a desired range. The buffer compound is also immobilized within the polymer. The polymer preferably has enzyme activity and a buffer capacity in excess of 3 micromoles acid or base per gram polymer. In one embodiment, each of the enzyme(s) and the buffer(s) are covalently bonded to the polymer.
