Disclosed herein are methods for reducing or arresting an increase in a Neuropathy Impairment Score (NIS) or a modified NIS (mNIS+7) in a human subject by administering an effective amount of a transthyretin (TTR)-inhibiting composition.

The present invention provides a cell-based assay for identifying and/or quantifying anti-CD3 homodimers in a composition comprising a T cell-dependent Bispecific antibody (TDB). In some aspects, the invention T cells comprising a T cell activation responsive reporter are contacted with the TDB to detect the presence of anti-CD3 homodimers. Compositions of reporter T cells and kits are also contemplated.

Disclosed are devices and methods for preparing pre-metabolized compound libraries and for screening compound metabolites in a high throughput format. The devices and methods disclosed herein increase the chemical diversity of a chemical library prior to screening, and thereby enhance the number and value of hits identified in such chemical screening efforts.

The invention generally relates to methods for the diagnosis and treatment of neurological and neurodegenerative diseases, disorders, and associated processes. Specifically, the present invention is directed toward methods to determine prognosis, diagnosis or efficacy of a therapeutic regimen by using a detectable label to measure levels of alpha-synuclein.

A method of preparing a bone graft. An osteoconductive matrix is placed in a receptacle. Bone marrow aspirate is provided that includes plasma, progenitor cells, hematopoietic cells, endothelial cells, red blood cells, white blood cells, platelets, bone, cartilage, thrombus or combinations thereof. The bone marrow aspirate is passed through the receptacle. At least a portion of bone marrow aspirate is retained in the receptacle. The portion of the bone marrow aspirate retained in the receptacle becomes associated with the osteoconductive matrix to form the bone graft.

A transgenic knockout non-human animal is described whose genome includes a heterozygous disruption of the expression of at least one endogenous gene encoding zinc-finger, CCHC domain-containing protein 6 (ZCCHC6). The transgenic animal model can be used to study bone disease or development by determining differences in bone characteristics, protein expression, or cytokine expression in the animal model in comparison to a corresponding wild-type non-human animal.

In various embodiments methods are provided for identifying and/or quantifying one or more antigens of interest (biomarkers) on the surface of cell- or tissue-specific exosomes. In an illustrative embodiments the methods comprise: i) incubating a population of exosomes with one or more tissue-specific antibodies that bind an antigen specific to a tissue or cell type of interest that produces exosomes, where the tissue specific antibodies are attached to acceptor bead or magnetic beads so the antibodies bind exosomes displaying the antigen; ii) obtaining a purified population of exosomes bound by the tissue specific antibodies with and/or without photo-cleavable linker based technology; iii) incubating a test subset of the isolated tissue-specific exosomes with acceptor beads attached to test antibodies that bind an antigen of interest thereby binding exosomes that display the antigen of interest and a control subset with negative control acceptor beads; v) incubating the test subset of isolated exosomes and the control subset of exosomes with a donor-bearing antibody that binds an exosome specific antigen; and vi) detecting a signal produced upon illumination of the control subset and/or the test; and vii) detecting the antigen(s) of interest.
