Abstract: Proteins that are differentially expressed or elevated in tissue and biofluids after central nervous system injuries are described. Elevated or reduced levels of the proteins, alone or in various combinations or ratios, can be used to assess severity of central nervous system injury (CNS injury) including traumatic brain injury (TBI), traumatic spinal cord injury (SCI) and chronic traumatic encephalopathy (CTE). Time course measurements post CNS-injury of these proteins can be used to monitor progress or recovery over periods up to several months. Differentiation of acute, subacute and chronic injury can be diagnosed by comparing the protein levels in CNS-injury patients at days 1-3, day 4-10 with levels at day 30-180 in comparison with normal controls.

Abstract: System and method for analyzing a sample for the presence of an analyte in a sample, the system comprising a sample holder for containing the sample; an excitation source in optical communication with the sample, wherein radiation from the excitation source is directed to the sample, and wherein the radiation induces a fluorescence signal; and at least one linear array comprising a proximal end disposed in proximity to the sample holder and an end port distal from the proximal end; a plurality of optical fibers extending from the proximal end to the end port and having a first end and a second end, wherein the first ends of the individual optical fibers are substantially coplanar and adjacent to one another, and wherein the second ends of the optical fibers form a non-linearly arranged bundle, and wherein the plurality of optical fibers transmits the fluorescent signal from the proximal end to the end port; and an end port assembly optically coupled to the end port, the end port assembly comprising a single p

Abstract: A system for analyzing a sample for the presence of an analyte in a sample. The system includes a sample holder for containing the sample; an excitation source, such as a laser, and at least one linear array radially disposed about the sample holder. Radiation from the excitation source is directed to the sample, and the radiation induces fluorescent light in the sample. Each linear array includes a plurality of fused silica optical fibers that receive the fluorescent light and transmits a fluorescent light signal from the first end to an optical end port of the linear array. An end port assembly having a photo-detector is optically coupled to the optical end port. The photo-detector detects the fluorescent light signal and converts the fluorescent light signal into an electrical signal.

Abstract: Methods for detection of the presence or absence of PrPSc in a biological sample suspected of having them comprising the steps of concentrating the PrPSc as may be present in the sample by substantially separating the PrPSc from the sample matrix; labeling the concentrated PrPSc with at least one molecular label to produce labeled PrPSc; and detecting the labeled PrPSc on an instrument capable of detecting an attomole quantity of labeled PrPSc, and wherein the duration of time between concentrating the PrPSc and analyzing the labeled PrPSc is about 48 hours or less.
