Abstract: Disclosed herein are panels related to the diagnosis of diseased tissue in a subject. The disclosed panels and related methods are used to predict or assess whether a subject has a neurodegenerative disorder taking into account the age of the subject. Some embodiments of the methods include applying a gene filter based on the age of the subject and generating an output of gene expression data which takes into account differences in gene profiles seen in tissues as they age.

Abstract: The subject invention provides colorimetric test strips and fast screening field test kits for differentiating between cannabinoids in cannabis samples, preferably, for differentiating marijuana from other cannabis plants, e.g., hemp. The fast screening field test kit can also be used for confirming the presence of marijuana in a complex cannabis sample. The colorimetric test strips use a solid substrate (e.g., capillary microextraction of volatiles (CMV) device) for the colorimetric reaction. The non-polar nature of the CMV sorbent does not allow the reaction of FBBB and THC to spread, producing an intense red color in the presence of a plant with high concentration of THC (e.g., marijuana) or an orange color in the presence of a plant with a high concentration of CBD (e.g., hemp).
