Abstract: An electronic device is provided, including a housing, a circuit board, an infrared generator, and a light guide member. The housing is provided with a light-transmitting hole and an accommodating cavity for accommodating the circuit board, the infrared generator, and the light guide member. The infrared generator is mounted on the circuit board. The light guide member includes a light incident surface and a light exit surface. The light guide member is at least partially arranged in the light-transmitting hole. The light incident surface and the light exit surface are arranged in a staggered manner. The light incident surface is arranged corresponding to the infrared generator, and the light incident surface is an aspherical curved surface. Infrared light emitted by the infrared generator emits outward through the light guide member.

Abstract: Compounds which inhibit Wza-mcdiated polysaccharide transport are useful in the prevention or treatment of bacterial infection, in particular of E. coli infection. The compounds are typically cyclic oligosaccharides such as cyclodextrins, which bear positively charged functional groups at the primary carbon position.
