  • Publication number: 20080160987
    Abstract: Methods, systems, and computer program products for silence insertion descriptor (SID) conversion are disclosed. According to one aspect, the subject matter described herein includes a method for silence insertion descriptor (SID) conversion. The method includes receiving a wireless frame, the frame identifying a first node as a frame source and a second node as a frame destination; determining whether tandem-free operation (TFO) is applicable; responsive to a determination that TFO is applicable, determining whether the frame is a SID frame; responsive to a determination that the frame is a SID frame, determining whether the SID format used by the first node is incompatible with the SID format used by the second node; and responsive to a determination that the SID format used by the first node is incompatible with the SID format used by the second node, converting the SID frame from the SID format used by the first node to the SID format used by the second node.

  • Publication number: 20080153870
    Abstract: A class of binding ligands for cocaine receptors and other receptors in the brain. Specifically, a novel family of compounds shows high binding specificity and activity, and, in a radiolabeled form, can be used to bind to these receptors, for biochemical assays and imaging techniques. Such imaging is useful for determining effective doses of new drug candidates in human populations. In addition, the high specificity, slow onset and long duration of the action of these compounds at the receptors makes them particularly well suited for therapeutic uses, for example as substitute medication for psychostimulant abuse. Some of these compounds may be useful in treating Parkinson's Disease or depression, by virtue of their inhibitory properties at monoamine transporters.

  • Patent number: 7202348
    Abstract: The present invention provides synthetic immunochemical haptens for the generation of antibodies that are designed to recognize the common molecular features of d-methamphetamine-like abused stimulants with insignificant cross-reactivity to endogenous substrates (e.g. dopamine) or over-the-counter medications (e.g. 1-methamphetamine, pseudoephedrine, phenylpropanolamine and ephedrine). These monoclonal antibodies and their antigen binding fragments are useful in treatment plans for recovering addicts, in emergency room settings for rapidly reversing a drug overdose, in protection of fetuses from drug-abusing pregnant mothers or in a psychiatric setting to reduce the exacerbation of psychotic disorders caused by stimulant drugs.

  • Publication number: 20060193309
    Abstract: The subject matter described herein includes methods, systems, and computer program products for providing TDM terminating services in a packet network. According to one method, a combined set including a plurality of TDM channels is received over a packet network. The combined set of TDM channels is terminated in the packet network as a combined TDM facility. Terminating the TDM channels as a combined TDM facility may include providing at least one terminating TDM service for the TDM channels, such as performing CAS signaling or providing a PRI interface for the TDM channels.

  • Patent number: 6358492
    Abstract: The 3&agr; isomer of RTI-55, RTI-352, is an effective in vivo binding ligand that reflects greater selectivity for the dopamine transporter than is observed with RTI-55. In addition, there is also a more rapid achievement of apparent equilibrium in the striatal-to-cerebellar ratio (compared to RTI-55) as the ratio peaks at about 30 min and is maintained for about 20 min thereafter. Such apparent equilibrium is useful in developing an approach to measuring the number of dopamine transporters present in tissues. Moreover, these results indicate that the utilization of 3&agr; isomers of a variety of 3&bgr;-(substituted phenyl)tropanes will result in greater selectivity for dopamine transporters and a more rapid of achievement of apparent equilibrium.
