Abstract: A communication device has memory for storing a client application module, a server application module, and an operating system module which are executable by one or more processors. The client application module submits a request and, in response, the server application module causes the request to be processed with use of the operating system module. An interface module causes one or more client process handles of a client stack of the client application module to be provided in a current process base of the operating system module. Thus, for the request, the operating system module checks one or more permission settings associated with the one or more client process handles as well as one or more permission settings associated with the one or more server process handles.

Abstract: The invention provides pharmaceutical compositions comprising short single stranded oligonucleotides, of length of between 8 and 26 nucleobases which are complementary to human microRNAs selected from the group consisting of miR19b, miR21, miR122a, miR155 and miR375. The short oligonucleotides are particularly effective at alleviating miRNA repression in vivo. It is found that the incorporation of high affinity nucleotide analogues into the oligonucleotides results in highly effective anti-microRNA molecules which appear to function via the formation of almost irreversible duplexes with the miRNA target, rather than RNA cleavage based mechanisms, such as mechanisms associated with RNaseH or RISC.

Abstract: A system (20) and method for assembling a prosthetic heart valve, including a procedure for sewing fabric (30) around a heart valve support stent (26). The system includes a support stent handling component that works in conjunction with a sewing machine component. The sewing machine has a bobbin (80), and the system includes a non-contact sensor (100) to monitor the passage of a needle thread loop (84) over the bobbin. The sensor may be a monitoring laser, and a controlling processor receives information therefrom for 100% real-time inspection of each stitch. The occurrence of an unsuccessful stitch may prompt the processor to repeat the stitch at a slower speed. The automation of the fabric sewing procedure greatly enhances manufacturing throughput and reduces ergonomic strain on workers.
