The present invention is directed generally to eukaryotic cells comprising single-celled organisms that are introduced into the eukaryotic cell through human intervention and which transfer to daughter cells of the eukaryotic cell, and methods of introducing such single-celled organisms into eukaryotic cells. The invention provides single-celled organisms that introduce a phenotype to eukaryotic cells that is maintained in daughter cells. The invention additionally provides eukaryotic cells containing magnetic bacteria. The invention further provides eukaryotic cells engineered with single-celled organisms to allow for multimodal observation of the eukaryotic cells. Each imaging method (or modality) allows the visualization of different aspects of anatomy and physiology, and combining these allows the imager to learn more about the subject being imaged.

Disclosed are multimeric compounds of K1 domains from the Hepatocyte Growth Factor/Scatter Factor (HGF/SF) being able to induce activation of the tyrosine kinase receptor MET and their uses.

The present invention provides polypeptides and their variants and derivatives which modulate GABA.sub.A receptor function at nanomolar quantities by binding to the α+/β− subunit interface, as well as methods of making and using the same. The inventive peptides are useful for the study of neurological disease and function and can have therapeutic applications.

Conformationally restricted cyanine fluorophores, as well as methods of making and using the compounds, are described. The conformationally restricted cyanine fluorophores have a chemical structure according to Formula I, or a stereoisomer or pharmaceutically acceptable salt thereof: ##STR00001##
wherein A is ##STR00002##
and wherein each “*” designates an attachment point of A.

The tumor stroma, which accounts for a large part of the tumor mass, represents an attractive target for the delivery of diagnostic and therapeutic compounds. Here, the focus is notably on a subpopulation of stromal cells, known as cancer-associated fibroblasts, which are present in more than 90% of epithelial carcinomas, including pancreatic, colon, and breast cancer. Cancer-associated fibroblasts feature high expression of FAP, which is not detectable in adult normal tissue but is associated with a poor prognosis in cancer patients. The present invention provides small-molecule radiopharmaceutical and imaging agents based on a FAP-specific inhibitor.

A chemigenetic calcium indicator and a method of measuring calcium are provided. The chemigenetic calcium indicator includes a calcium-binding protein domain attached to a ligand binding protein domain. The method of measuring calcium includes administering a chemigenetic calcium indicator to a subject and determining changes in fluorescence, the chemigenetic calcium indicator including a ligand binding protein domain having a calcium-binding protein domain and a dye-ligand conjugate attached thereto.

Compositions and methods for visualizing tissue under illumination with near-infrared radiation, including compounds comprising near-infrared, closed chain, sulfo-cyanine dyes and prostate specific membrane antigen ligands are disclosed.

Disclosed herein are methods relating to manufacturing an embolizing agent precursor. Manufacture of the embolizing agent precursor may involve mixing a first component contained within a first container with a second component contained within a second container, the first component including a plurality of negatively charged gaseous components and a first stabilizer, the second component comprising a plurality of positively charged oil components, a second stabilizer, and a cationic surfactant. Further steps may include mixing the first component with the second component such that the first and second component are held together as a single agglomerated entity.

Antibodies that include a sulfatase motif-containing tag in a constant region of an immunoglobulin (Ig) heavy chain polypeptide are disclosed. The sulfatase motif can be converted by a formylglycine-generating enzyme (FGE) to produce a formylglycine (fGly)-modified Ig heavy chain polypeptide. An fGly-modified Ig heavy chain polypeptide of the antibody can be covalently and site-specifically bound to a moiety of interest to provide an antibody conjugate. The disclosure also encompasses methods of production of such tagged Ig heavy chain polypeptides, fGly-modified Ig heavy chain polypeptides, and antibody conjugates, as well as methods of use of same.

Provided here are therapeutically effective pharmaceutical compositions containing one or more TREX2 inhibitors, and more specifically methods of administering TREX2 inhibitors to increase the effectiveness of a chemotherapeutic agent. Also provided here are methods of identifying agents that inhibit the exonuclease activity of TREX2.
