Abstract: A method of diagnosing and prognosticating an acquired central nervous system injury (ACNSI) in a subject that includes: (a) obtaining a test sample from the subject (b) comparing levels a biomarker in the test sample with known normal or abnormal reference levels of the biomarker. A change (increase or decrease) in the levels of the biomarker in the test sample relative to the known reference levels of the biomarker is indicative of ACNSI diagnosis in the subject, the biomarker being one or a combination of two or more of the proteins listed in Table 2. ACNSI includes concussion and primary blast in blast-induced traumatic brain injury.

Abstract: Systems and methods for providing navigational marks on a fingerboard of a stringed instrument are provided. An example system may allow enhanced navigating of a player on the fingerboard of the stringed instrument. The system may comprise the fingerboard of the stringed instrument. Strings may be attached to the instrument over the fingerboard. A note may be produced by stimulating a part of a string associated with the note. The part of the string may be called a note location on the fingerboard. The navigational marks may be disposed on the fingerboard in association with the strings to mark note locations on the fingerboard and thus facilitate finding the note location. The navigational marks may include a plurality of types, with each type associated with a note of an octave and having a specific shape.
