System and method includes a body having a central microchannel separated by one or more porous membranes. The membranes are configured to divide the central microchannel into a two or more parallel central microchannels, wherein one or more first fluids are applied through the first central microchannel and one or more second fluids are applied through the second or more central microchannels. The surfaces of each porous membrane can be coated with cell adhesive molecules to support the attachment of cells and promote their organization into tissues on the upper and lower surface of the membrane. The pores may be large enough to only permit exchange of gases and small chemicals, or to permit migration and transchannel passage of large proteins and whole living cells. Fluid pressure, flow and channel geometry also may be varied to apply a desired mechanical force to one or both tissue layers.

A method for treating, remedying, or preventing inflammatory skin disorders by administering a therapeutically effective dose of at least one an antagonist of a calcitonin gene-related peptide receptor in a pharmaceutically acceptable formulation. The method for treating, remedying, or preventing an inflammatory skin disorder by administering topically and to the prepsoriatic rim a therapeutically effective dose of at least one an antagonist of a calcitonin gene-related peptide receptor in a pharmaceutically acceptable formulation.

Methods for identifying animals that are genetically superior, drugs, nutritional strategies, or physiological manipulations that improve feed efficiency or productivity of animals, e.g., selecting animals that are genetically superior for feed efficiency or productivity based on metabolic rates of particular tissues, wherein metabolic rates of certain tissues such as skeletal muscle are inversely proportional to feed efficiency, while metabolic rates of other tissues such as mammary gland are directly proportional to milk production. Thus, animals with low skeletal muscle metabolic rates are generally more feed efficient, e.g., gain more weight per unit of food. The methods herein may be used to improve the genetics, nutrition, and handling or animals more efficiently produced animal products, e.g., meat production, milk, production, egg production, wool production, etc. The methods herein may also be used to determine estimated breeding values of animals for feed efficiency, growth, or production.

The present disclosure provides methods of determining A-beta in a mammal before and after treatment of an amyloid disorder, comprising obtaining a first blood sample from the mammal; administering to the mammal a treatment for an amyloid disorder; obtaining a second blood sample from the mammal; quantifying a level of A-beta in the first blood sample and in the second blood sample; and determining the level of A-beta in the mammal before and after treatment of the amyloid disorder.

The invention relates to a method of identifying stereodefined phosphorothioate oligonucleotide variants with reduced toxicity by creating and screening libraries of stereodefined chiral phosphorothioate variants for compounds with reduced toxicity, either in vitro or in vivo.

A transgenic animal model that is suitable for the cell or tissue specific assessing of thyroid hormone (TH) action in vivo is described. The recombinant DNA construct and methods suitable to generate such an animal are also provided. The assessment of TH action is based on a reporter that is dependent on an endogenously expressed thyroid hormone receptor (TR) and coregulators of said receptor.

Tools for characterizing uptake of therapeutic compounds by target tissue are disclosed along with methods for determining dosing regimen from the uptake parameters. Uptake parameters considered include partition coefficient, diffusivity, and equilibrium uptake ratio. Systems for determining partition coefficient and diffusivity in rapid uptake combinations of compounds and tissue are also reported.

The present disclosure provides a substrate for cell culture. Systems comprising the substrate, and methods for using and manufacturing the substrate are also disclosed herein.

The use of Slfn11 as a biomarker for detecting the occurrence of epithlial-to-mesenchymal transition (EMT) in a subject, and the use of Slfn11 modulators to treat cancer is disclosed herein. Also disclosed are various methods for detecting the occurrence of epithelial-to-mesenchymal transition (EMT) in a subject by measuring Slfn11 expression and/or activity.

System, method and computer readable medium that assess characteristics of an embryo by processing video image data of the embryo. Video is obtained, typically from third parties, of a target embryo. The video has frame speed of two frames per second, or faster and includes image data representing morphokinetic movement of the embryo. The image data is processed using a trained machine learning model that assesses embryo characteristics. The video has a duration of ten minutes or less. The assessment can be a prediction of a likelihood the embryo is viable and/or will produce a pregnancy upon transfer into a recipient. Further, the assessment can predict a likelihood the embryo will: (1) produce offspring having a specific sex; (2) embody a genetic anomaly; (3) perpetuate desired traits in produced offspring and/or (4) produce undesired characteristics in produced offspring.
