Abstract: Both purinergic signaling through nucleotides such as ATP and noradrenergic signaling through molecules such as norepinephrine regulate vascular tone and blood pressure. Pannexin1 (Panx1), which forms large-pore, ATP-releasing channels, is present in vascular smooth muscle cells in peripheral blood vessels and participates in noradrenergic responses. Using pharmacological approaches and mice conditionally lacking Panx1 in smooth muscle cells, we found that Panx1 contributed to vasoconstriction mediated by the ?1 adrenoreceptor (?1AR), whereas vasoconstriction in response to serotonin or endothelin-1 was independent of Panx1. Analysis of the Panx1-deficient mice showed that Panx1 contributed to blood pressure regulation especially during the night cycle when sympathetic nervous activity is highest. Using mimetic peptides and site-directed mutagenesis, we identified a specific amino acid sequence in the Panx1 intracellular loop that is essential for activation by ?1AR signaling.

Abstract: An in-wall amplifier assembly includes a wireless communication device and an amplifier located inside a first housing configured for in-wall installation, with the amplifier configured to amplify the audio output from the wireless communication device and supply it to external speakers. An AC/DC adapter located in a second housing can be connected thereto to supply DC power to the amplifier and wireless communication device. The wireless communication device can be removably accommodated in a faceplate of the first housing and held in place by a wall plate installed thereover. The amplifier can accept an external audio input from another source and automatically switch the amplified audio output between the output of the wireless communication device and the external audio input.

Abstract: The invention is directed to a method of preserving accuracy in dual-ended frame loss measurement system between a first node and a second node in a packet switching network, especially by Ethernet routers, switches and bridges supporting ITU-T Y.1731 dual-ended LM functionality by enhancing the behavior of dual-ended frame loss measurement to permit enabling and disabling the loss measurement at each node separately without incurring erroneous errors.

Abstract: A suture anchor is described which in one form may be easily fabricated from extruded material by angular cuts and bore holes which provide an offset pulling force to the suture. In an alternate and preferred embodiment the suture anchor is injection molded having an annular displaced corner and abutment wall which act to seat the suture anchor firmly within a bore hole. Novel application means are also disclosed which hold the suture anchor on a frangible shaft for insertion and upon completion of the insertion permit fracture of the frangible portion and removal of the instrument.
