Abstract: The disclosure provides a rapidly deployable nanoscale biodegradable system using hydroxypropyl beta cyclodextrin based combination product. Cyclodextrin is an amphiphilic polymer suitable to develop an agnostic barrier blocking pathogenic mi-crobes that has localized on the mucocutaneous lining of the conjunctiva, mouth and nose, lung, or gastrointestinal tract. The cyclodex-trin may bind the viral particles and/or disrupt viral entry mechanisms by removing cholesterol from viral particles to reduce infectivity. Cyclodextrins also may facilitate removal of the viral cholesterol molecules, thus rendering them less viable. Cyclodextrin activity may be further enhanced when used in combination with certain minerals and/or antioxidant compounds.

Abstract: A method of identifying subjects with colorectal cancer (CRC) is provided. The method includes obtaining a sample from a subject, determining a level of one or more folate one carbon metabolism (FOCM) metabolites in the sample of the subject, and comparing the level of the FOCM metabolites in the sample of the subject to a level in a non CRC control.
