Abstract: An improved method is described for making single isomers of synthetic benzoprostacyclin analogue compounds, in particular the pharmacologically active 314-d isomer of beraprost. In contrast to the prior art, the method is stereoselective and requires fewer steps than the known methods for making these compounds.

Abstract: Probes which target diffuse and fibrillar forms of amyloid beta (A?) are described. These probes demonstrate high initial brain penetration and facile clearance from non-targeted regions. The agents can be used to image amyloid quantitatively for monitoring efficacy of A?-modifying therapeutics and assist in premortem diagnosis of Alzheimer's disease (AD). Disclosed probes can bind A? aggregates of preformed A?1-42 fibrils in vitro and can be used to image fibrillar and diffuse plaques ex vivo in brain sections. Disclosed probes can be used to determine A? burden in early stages of AD. These probes can be used for multimodality imaging of A?. F-AI-187(1 ?M) can detect A? plaques in brain sections of APP/PS1 mice. F-AI-187(10 ?M) can detect A? plaques in the frontal lobe in a brain section of a patient with confirmed AD. Some probes can be used for fluorescence imaging of plaque.

Abstract: A computer system includes a first on-chip controller and a second on-chip controller, both connected to a control element. In normal operation, the first and second on-chip controllers operate in different clock domains. During testing, the control element causes each on-chip controller to generate a substantially similar clock signal. The substantially similar clock signals are used to test substantially similar test circuitry connected to each on-chip controller, thereby reducing overhead associated with testing. A delay may be incorporated into the path of the clock signal of one of the on-chip controllers to reduce instantaneous power draw during testing.

Abstract: A SCAN chain architecture for each path in a circuit having combinational paths includes a control mechanism to control one or more flip flops and multiplexers to direct operational or test signals. Operational signals are sent along at least one combinational path to a pull-up/pull-down for at least one input/output pad and an operational voltage is recorded. Test signals are sent along at least one alternative path to an alternative input/output and a test voltage is recorded. The operational voltage is compared to the test voltage to identify a combinational path fault.
