Abstract: A method of treating a subject having Alzheimer's disease can include assaying a biological medium obtained from the subject for a biomarker selected from the group consisting of Biomarker 1, Biomarker 2, Biomarker 3, Biomarker 4, Biomarker 5, Biomarker 6, Biomarker 7, Biomarker 8, Biomarker 9, Biomarker 10, Biomarker 11, and combinations thereof, where Biomarker 1 has a mass-to-charge ratio (m/z) of 229.13, Biomarker 2 has a m/z of 514.38, Biomarker 3 has a m/z of 602.44, Biomarker 4 has a m/z of 620.42, Biomarker 5 has a m/z of 630.47, Biomarker 6 has a m/z of 703.56, Biomarker 7 has a m/z of 724.52, Biomarker 8 has a m/z of 778.54, Biomarker 9 has a m/z of 799.66, Biomarker 10 has a m/z of 824.60, and Biomarker 11 has a m/z of 842.61. The method can also include relating a characteristic of the biomarker to a presence of Alzheimer's disease in the subject and treating the subject for Alzheimer's disease.

Abstract: Described herein are methods for evaluating the risk of preterm birth in pregnant subjects. The methods involve detecting and quantifying one or more biomarkers associated with preterm birth in a biological sample from the subject. Also described herein are isolated biomarkers and kits useful in predicting the risk of preterm birth.

Abstract: A panel of lipid biomarkers of preeclampsia in pregnant women, useful prior to onset of symptoms to identify women at risk of preeclampsia as early as 12-14 weeks gestation is disclosed. Methods of diagnosing a pregnant subject at risk of developing preeclampsia, and methods of reducing symptoms or preventing the onset of preeclampsia in a pregnant subject, employing the disclosed lipid biomarkers are also disclosed.

Abstract: Lipid biomarkers for early detection of production-related metabolic disease in cattle are disclosed. The biomarkers are obtained from colostrum or milk. Methods for using and analyzing such lipid biomarkers, and methods for managing and treating dairy cattle are disclosed.

Abstract: Methods for proteomic analysis are provided. For example, in one aspect a method for identifying and sequencing a peptide may include fractionating a biological sample containing a peptide of interest to at least partially isolate the peptide, obtaining mass spectra of the peptide, and accelerating the peptide into a collision chamber at a plurality of discrete collision energies for a discrete period of time to form a plurality of peptide fragments for each of the plurality of discrete collision energies.
