Abstract: Non-invasive methods permitting accurate detection of innate immune dysfunction are critical to enhance the understanding, diagnosis, and treatment of inflammatory disorders. Identifying specific biomarkers of innate immune cells and their functional phenotypes, paired with subsequent PET tracer development, is thus an area of great interest with important implications for a broad range of diseases. However, existing targets lack cell specificity and/or fail to provide functionally relevant information regarding immune cell status. To overcome these limitations, a PET tracer was developed targeting TREM1 a highly specific biomarker of pro-inflammatory myeloid-driven immune responses.

Abstract: The present disclosure provides for methods and compositions useful for imaging inflammation and inflammatory disease markers with an affinity for TREM-1 antibodies. The methods and compositions can include a labeled probe having a TREM-1 antibody and a radiolabel.

Abstract: The present disclosure provides a positron emission tomography (PET)-detectable 1-((2-fluoro-6-[18F]fluorophenyl)sulfonyl)-4-((4-methoxyphenyl)sulfonyl)piperazine ([18F]DASA-23) probe that can selectively bind to the pyruvate kinase variant M2 (PKM2) found in cancer cells, such as of human glioma. Given the importance of PKM2 in the regulation of tumor metabolism, there is an on-going need to non-invasively measure its expression through the development of PKM2-specific radiopharmaceuticals. Precursors useful for the synthesis of the radiolabeled [18F]DASA-23-PKM2-specific probe and related compounds, and their methods of synthesis, are provided. Since the half-life of the 18F isotope is approximately 110 min, it is advantageous for a practitioner to attach the radionuclide to the precursor shortly before administration. Therefore, a precursor compound suitable for receiving the radionuclide and capable of specifically binding to the PKM2 variant can be provided.

Abstract: A novel pyruvate kinase M2 (PKM2)-specific activator, [11C]DASA-23 and derivatives thereof, and methods for their rapid synthesis are provided. The probes are particularly useful in methods for the non-invasive positron emission tomography (PET) detection and imaging of PKM2 expression in subcutaneous and orthotopic tumors. [11C]DASA-23 cell uptake correlates with PKM2 protein expression in cultured tumor cells and orthotopic tumors are delineated from the surrounding normal brain tissue in vivo.

Abstract: A method for localizing and quantifying S1R role in nociceptive processing; for providing a guide to providing an analgesic therapy; of using an S1R selective ligand as a biomarker for pathphysiological study of memory deficits and cognitive disorders; or of detecting increased S1R density at the site of nerve injury arising from neuropathic pain comprising using as a probe at least one SR1 selective compound or radioligand of the general formula III?, or IV?:

Abstract: Compounds having the general formula III?, or IV? wherein R1 can be a radical of an optionally substituted C-4 to C-7 N-containing heterocycle or a radical of an optionally substituted cyclic or acyclic tertiary amine or isoindoline-1,3-dione: R2,4,5,6 can each independently be any one or combinations of the following moieties, cyano, nitro, acyl, alkyl, amido, azido, isothiocyanate, isocyanate, optionally substituted anilino, halogens, ethers, sulfonamides, thioacyl, nitro, aromatic, heterocyclic, olefinic, acetylene, deuterium, or tritium; Y is S; Z can be either H, O, S, S—R or NR where R groups can be either H, aryls, alkyls, or cycloalkyls; “n” can be 1 to 5 carbons in length and stereoisomers, functional analogs, and pharmaceutically acceptable salts thereof and wherein the moiety bridging R1 and N can be a substituted alkylene, optionally substituted alkenylene or optionally substituted alkynylene and where the alkylene group can include an inserted C3-C5 cycloalkyl group, aromatic, and heterocycli

Abstract: This is a camera strap which encircles the user's wrist in the manner of a cinching-style mechanism which is user adjustable and/or adjusted by the hanging weight of the attached camera. The strap utilizes the two connecting points on either side of the camera body. The cinching wrist strap will attach to those two connecting points via a loop of webbing and retention clips. Quick release buckles allow the user to disconnect and/or interchange straps in a quick manner. This method of attaching the camera to the user's wrist allows ease of use and offers additional security.
