Abstract: A NLRP3-inhibitory compound 7 (NIC7) and a potent derivative NIC7w are disclosed. NLRP3-inhibitory compound 7 (NIC7) and a potent derivative NIC7w are a novel small-molecule inhibitor for inhibiting NLRP3 inflammasomes are identified. These compounds inhibit main elements of the NLRP3 signaling pathway, primarily IL-1? and caspase 1, and improve cognitive behaviors of mice in Alzheimer disease mouse models. Compositions of NIC7 and NIC7w are suitable as a therapeutic agent in treating, preventing, or improving the conditions of Alzheimer's disease.

Abstract: A video decoding apparatus decodes a sequence of one or more pictures in the unit of blocks which are split from each picture. The apparatus comprising a decoder configured to reconstruct, from a bitstream, a current motion vector difference of the current block among the blocks which belong to the sequence of one or more pictures, and an image decoder configured to predict and decode the current block using the motion vector of the current block. When the current motion vector difference of the current block is zero, the resolution of the current motion vector difference of the current block is set to the ¼ pixel precision without the information on the motion vector resolution extracted.
