    Abstract: Provided is a configuration capable of executing a detection test for a comfort level including the quality of sleep, which is measurable at home without requiring the measurement of brain waves or electrocardiogram. The respiratory waveform of a subject during sleep is continuously measured and recorded from the respiratory gas flow, etc., and is window-Fourier transformed at each measurement time to generate a frequency spectrum, and a bandwidth including a respiratory frequency is extracted. The index indicating the regularity of the respiratory period of the subject is also calculated at each time point during the sleep, and the time-dependency of this index during the sleep is represented as a graph. A medical device includes a sleep evaluation system equipped with a control means for performing control so that a sleep cycle repeated at a cycle of about 90 minutes is clearly observed if the comfort level including the quality of sleep of the subject is favorable.

    Abstract: Provided herein are methods, systems, and compositions for Lp-PLA2 detection assays that employ amounts of detergent to liberate all or nearly all of the Lp-PLA2 molecules from associated lipoprotein particles. In this regard, the true Lp-PLA2 concentration can be detected in a sample, which correlates better with known Lp-PLA2 activity assays.

    Abstract: Provided herein are methods, systems, and compositions for detecting one or more HDL-associated proteins (e.g., ApoC3; ApoC3 and ApoA1; ApoC3 and SAA1/2; or proteins in Biomarker Panels 1-30) in a sample from a subject with, or suspected of having, cardiovascular disease (CVD) or other HDL related disease. In certain embodiments, such methods, systems, and compositions are used to determine the approximate risk of CVD (or other disease) for a subject, and/or the approximate cholesterol efflux capacity (CEC) of a sample.

    Abstract: Provided herein are compositions, systems, and methods for extracting and detecting at least one HDL-associated protein (e.g., ApoA1) from a sample (e.g., plasma or serum sample). In certain embodiments, a strong organic acid and hydrophilic organic solvent are mixed with the sample; after centrifugation, the supernatant is transferred to a second container where it is mixed with a non-polar organic solvent; after centrifugation, the lower aqueous layer is transferred to a third container; and then at least a portion of the transferred aqueous layer is subjected to a detection assay such that at least one HDL-associated protein is detected.

    Abstract: The present invention provides methods, kits, and compositions for purifying HDL molecules from a sample (e.g., blood sample) using HDL tagging molecules comprising an HDL lipophilic core binding peptide (e.g., portion of ApoA1) and an affinity tag. The present invention also provides methods, kits, and compositions for detecting non-fragmented ApoA1 with mass spectrometry. The present invention further provides methods, kits, and compositions for tagging HDL molecules in a sample with detectably labeled ApoA1 molecules such that the ratio of detectably labeled ApoA1 molecules to native ApoA1 proteins may be determined.
