Abstract: The present invention provides compounds and compositions, e.g., a series of compounds wherein a 1,5-biarylpyrazole group is conjugated to a urea group by a non-cleavable covalent chain, that are useful as dual COX-2/sEH inhibitors. The compounds disclosed herein have activity associated with the arachidonate cascade. The activity of these compounds was demonstrated using a lipopolysaccharide (LPS) induced model of pain in the rat. The compounds of the present invention demonstrated superior anti-allodynic activity as compared to the same dose of celecoxib, i.e., a COX-2 inhibitor, also as compared to the same dose of t-AUCB, i.e., a sEH inhibitor, and also as compared to the co-administered same dose of both celecoxib and t-AUCB. The dual inhibitors of the present invention demonstrate enhanced in vivo anti-allodynic activity in a nociceptive behavioral assay.

Abstract: Methods and apparatus are provided for supporting a variable-length transport packet in an Audio/Video (AV) communication system. Data to be transmitted is determined. It is determined whether a transport packet is the variable-length transport packet. A header having information indicating whether the transport packet is the variable-length transport packet is generated. When the transport packet is the variable-length transport packet, an optional header having length information of the transport packet is generated, and the data and the transport packet having the header and the optional header, are transmitted. When the transport packet is not the variable-length transport packet, the determined data and the transport packet having the header are transmitted.
