    摘要: Methods, systems and computer-accessible medium for imaging a living cell or a living organism with bond-edited compounds using stimulated Raman scattering are disclosed. The method comprises the steps of introducing one or more bond-edited compounds into a live cell or a living organism, and detecting a vibrational tag in the cell or organism with stimulated Raman scattering. Also disclosed are methods for detecting a disease condition in a subject, methods for monitoring treatment for a disease condition, methods for screening an agent, methods for tracing a cellular process in a live cell using bond-edited compounds in combination with stimulated Raman scattering. Also disclosed are a composition for labeling a target cell with at least one bond-edited compound and devices for imaging bond-edited compounds by stimulated Raman scattering.

    摘要: The present invention provides methods of detecting ultraviolet radiation (UVR)-induced skin damage in a subject. The method includes the steps of: a) obtaining a skin sample from the subject; b) analyzing expression levels in the skin sample of UVR-induced differentially expressed genes (DEGs) listed in Table 8 or a subset thereof; and c) comparing the expression levels of the UVR-induced DEGs to a control skin sample; wherein, when the expression levels of the UVR-induced DEGs in the skin sample is above or below the level of each of the UVR-induced DEGs in the control sample, the subject is identified as likely being afflicted with UVR-induced skin damage. Also provided are methods for measuring the effectiveness of a test agent in reducing ultraviolet radiation (UVR)-induced damage.
