Genetically modified rodents such as mice and rats, and methods and compositions for making and using the same, are provided. The rodents comprise a humanization of at least one endogenous rodent Tmprss gene, such as an endogenous rodent Tmprss2, Tmprss4, or Tmprss11d gene.

Methods of producing non-human animal models of corneal angiogenesis and corneal ectatic diseases, such as corneal keratoconus, by applying an aromatic compound to the eye of a non-human animal are described. Also described are non-human animal models of corneal angiogenesis and corneal ectatic diseases, and methods of using the non-human animal models to screen compounds that modulate corneal angiogenesis and corneal ectatic diseases.

An animal-based chemical detectors that can be customized to detect a wide variety of chemicals under real-world conditions. Methods and systems for brain/machine interface devices using electrodes to read odor-signatures from the patterns of activated glomeruli, for example in the rodent olfactory bulb.

A genetically modified canine has at least one edited chromosomal sequence. The edited chromosomal sequence is insulin-like growth factor 1 gene (IGF-1). The IGF-1 gene contains intronic splicing efficiency regions. The individual intronic splicing efficiency regions are altered individually or as a set order to change the IGF-1 gene.

The protective boots are wrap style boots that cover and protective the canine's paws and upper legs and include thin internal stiffeners that prevent the boot from sagging down the dog's leg. The stiffeners are a thin narrow strip of polymeric plastic. Each boot has a central stay stiffener and a pair of side stiffeners. The central stay stiffener covers the sole of the boot and extends up the length of the boot's back stay reinforcing the boot's sole and back stay. The side stiffeners sandwich and reinforce the boot's upper around the canine's leg. The protective boot is secured about the canine leg by laces and a pair of straps, which also helps prevent the boot from sliding or sagging over the canine wrist.

The present invention relates to expression cassettes and vectors comprising Alzheimer's disease-related genes and a cell line transformed by the disclosed expression cassettes and vectors, and more specifically, the expression cassettes according to the present invention comprise amyloid precursor protein (APP), Tau protein, and presenilin-1 (PS1) genes associated with Alzheimer's disease so that mutant genes thereof can be simultaneously expressed. Additionally, the present invention relates to a cell line transformed by the disclosed expression cassettes or vectors comprising APP, Tau protein, and PS1 genes, and further, to an animal model transformed by the vectors or cell line.

Detection and prediction of laminitis risk in equine may be provided by receiving, from a user, input features related to an equine subject at a laminitis risk detection model; responsive to receiving the input features, calculating a laminitis risk score for the subject; determining a laminitis prediction and a treatment suggestion for the equine subject based on the input features and the laminitis risk score; and outputting the laminitis risk score, laminitis prediction and treatment suggestion to the user.

The present invention relates to compositions and methods of reducing fertility and/or preventing puberty in prepubescent non-human subjects (e.g., kittens and puppies) by administering a composition comprising a vector comprising a nucleic acid encoding a Mullerian Inhibiting Substance (MIS) operatively linked to one or more regulatory elements. In some embodiments, administration is via a single or multiple injection. Other aspects relate to method and compositions for delaying puberty in a human female subject by administering a recombinant human MIS variant protein.

Genetically modified non-human animals and methods and compositions for making and using the same are provided, wherein the genetic modification comprises a humanization of an endogenous signal-regulatory protein gene, in particular a humanization of a SIRP? gene. Genetically modified mice are described, including mice that express a human or humanized SIRP? protein from an endogenous SIRP? locus.

The invention provides methods for isolating cell-type specific mRNAs by selectively isolating ribosomes or proteins that bind mRNA in a cell type specific manner, and, thereby, the mRNA hound to the ribosomes or proteins that bind mRNA. Ribosomes, which are riboprotein complexes, bind mRNA that is being actively translated in cells. According to the methods of the invention, cells are engineered to express a molecularly tagged ribosomal protein or protein that binds mRNA by introducing into the cell a nucleic acid comprising a nucleotide sequence encoding a ribosomal protein or protein that binds mRNA fused to a nucleotide sequence encoding a peptide tag. The tagged ribosome or mRNA binding protein can then be isolated, along with the mRNA bound to the tagged ribosome or mRNA binding protein, and the mRNA isolated and further used for gene expression analysis. The methods of the invention facilitate the analysis and quantification of gene expression in the selected cell type present within a heterogeneous cell mixture, without the need to isolate the cells of that cell type as a preliminary step.
