Abstract: This document provides methods and materials for treating aging. For example, a mammal having, or at risk for developing, an age-related impairment (e.g., age-related cognitive decline) can be treated by increasing the level of one or more myokine polypeptides (e.g., one or more Klotho polypeptides) within cells within the mammal. This document also provides methods and materials for increasing the ability of muscle progenitor cells to regenerate muscle cells by increasing the level(s) of one or more myokine polypeptides (e.g., an ?-Klotho polypeptide) within a muscle progenitor cell.

Abstract: Methods and systems for detecting foreign material within a product stream in real-time, involve illuminating a portion of the agricultural product stream with light spanning a wavelength range including or within near-infrared and/or shortwave infrared wavelengths; scanning a line of the illuminated agricultural product stream to acquire a hyperspectral image of the line, the hyperspectral image of the line having a width of a single pixel; processing the hyperspectral image of the scanned line to obtain spectrum data for one or more pixels of the hyperspectral image of the scanned line; comparing the obtained spectrum data of the one or more pixels to predetermined spectrum data to determine whether the obtained spectrum data is indicative of foreign material within the scanned line of the agricultural product stream.

Abstract: A method of inspecting for micro-cracks in a coated piece that includes a substrate and a coating, the method comprising generating a responsive spectral response from an area of inspection of the coated piece by irradiating at least a portion of the coated piece, the area of inspection being less than a predetermined nominal dimension of a micro-crack, and analyzing the responsive spectral response to determine whether a micro-crack exists in the coating, including by comparing the responsive spectral response to one or more predetermined spectral values to determine whether the responsive spectral response corresponds to a response associated with a substrate such as the substrate in the coated piece.
