  • Patent number: 9926589
    Abstract: A complex mixture is analyzed for multiple nucleic acid sequences (e.g., DNA or RNA sequences) simultaneously by target specific multiplex amplification followed by single molecule detection of amplicons by Atomic Force Microscopy (AFM). The presence or absence of target nucleic acids can be determined from the presence or absence of specific amplicons for those nucleic acids. In addition, quantification of target nucleic acids in the complex mixture is achieved by determination of the numbers of amplicons.

  • Patent number: 9906431
    Abstract: Time-critical Location Based Service (LBS) applications in mobile ad hoc networks (MANETs) require fast localization. An On-Demand Fast Localization (ODFL) start from multi-coordinate systems, and the position transformation is integrated with LBS application information transmissions. The framework of ODFL turns two pipe-lined procedures into two semi-concurrent procedures by employing coordinate system transformation on a per hop basis, which consists of three components: (1) Local Coordinate System (LCS) construction; (2) embedded information selection; and (3) position transformation.

  • Patent number: 9884836
    Abstract: A family of compounds which function as selective ligands for the serotonin receptor 2B (5-HT2B) is identified. Some of the compounds are synthetic non-natural ligands which have a relatively strong interaction with 5-HT2B compared to naturally occurring compounds (some of which are identified for the first time herein as ligands for 5-HT2B). Because the compounds, both naturally occurring and synthetically produced, function as ligands for 5-HT2B they will have application in, for example, the treatment and/or prevention of nervous system disorders such as Alzheimer's disease.

  • Publication number: 20170326086
    Abstract: Methods which increase the bioavailability of beneficial gases in the circulatory system are provided. The methods involve administering agents that changes the binding affinity of a medicinal gas such as NO, CO, H2S, N2O, SO, SO2 and O2 for IIb and/or hemoglobin based oxygen carriers (HBOCs). The change results in increased release of gases carried by Hb and HBOCs. As a result, the concentration of the gases in circulation is raised, and they are more available to exert their beneficial effects, e.g. in the treatment of disease or conditions caused by low levels of the gases. The methods are optionally used together with administration of medicinal gases and/or administration of HBOCs and/or other non-HBOC gas carriers such as PFC, and as (or in conjunction with) diagnostic methods.
