    • Methods for quantifying biospecimen sample integrity using markers of oxidation (FIG. 1). Under conditions of incomplete blood plasma/serum (P IS) sample freezing (including storage at −20 ?C), two different forms of oxidation occur spontaneously at protein sulfur atoms—namely S-cysteinylation of free cysteine residues (in which the oxidative event is disulfide bond formation) and sulfoxidation of methionine. Oxidized forms of albumin and apoA-1, SCA and MOA1 are useful markers of biospecimen integrity. The oxidative chemistries of SCA and MOAI are operational in other proteins and polypeptides. Thus, for rare cases in which the use of SCA or MOA1 may be contraindicated, custom designed surrogate peptide probes based on SCA and MOA1 oxidation chemistry may be fortified into samples at collection to serve as exogenous markers of P/S sample integrity.
    • 使用氧化标记物定量生物样本样品完整性的方法(图1)。 在不完全血浆/血清(P IS)样品冷冻(包括-20℃下保存)的条件下,两种不同形式的氧化在蛋白质硫原子上自发发生,即游离半胱氨酸残基的S-半胱氨酰化(其中氧化事件 是二硫键形成)和甲硫氨酸的亚磺氧化。 白蛋白和apoA-1,SCA和MOA1的氧化形式是生物样本完整性的有用标记。 SCA和MOAI的氧化化学物质在其他蛋白质和多肽中是可操作的。 因此,对于可能禁忌使用SCA或MOA1的罕见情况,可以采集基于SCA和MOA1氧化化学的定制设计的替代肽探针,以收集样品,以充当P / S样品完整性的外源标记。

    • The present invention relates to improved ion mobility analysis (IMA) methods that can accurately quantify particle concentration in a sample solution. Specifically, reference particles of known solution-phase concentration are used for calibration. In addition, by exploiting spectral deconvolution techniques, the concentrations of subpopulations within the particles can also be accurately quantified. The improved IMA methods permit, for the first time, the quantification of absolute concentrations of HDL particles and subpopulations thereof in a biological sample. The correlations of HDL particle concentrations and conditions such as LCAT deficiency and cardiovascular diseases have been established. Accordingly, the present invention also provide methods to determine whether a subject is at risk to develop or is suffering from these conditions by using HDL particle concentration as a clinical metric.
    • 本发明涉及可以准确量化样品溶液中的颗粒浓度的改进的离子迁移率分析(IMA)方法。 具体地,使用已知溶液相浓度的参比颗粒进行校准。 此外,通过利用光谱去卷积技术,也可以精确量化颗粒内亚群的浓度。 改进的IMA方法首次允许定量生物样品中HDL颗粒及其亚群的绝对浓度。 已经建立了HDL颗粒浓度与LCAT缺陷和心血管疾病等相关因素。 因此,本发明还提供了通过使用HDL颗粒浓度作为临床量度来确定受试者是否处于发展风险或正在遭受这些病症的方法。

    • The invention provides improved methods for analyzing cardiovascular disease risk. According to the invention, an algorithm that considers LDL and HDL subfractions, along with Lp(a) provides significant improvement in predicting CVD versus standard assays that include standard risk factors. Methods of the invention comprise measuring LDL and HDL subfractions in addition to Lp(a) without reference to standard risk factor measurements, such as CRP, total cholesterol, body mass index, weight, triglycerides, and the like. It is unexpected that an algorithm focusing only on LDL and HDL subfractions and Lp(a) would be more informative as to CVD risk than measurements that are much more comprehensive in terms of the markers that are reviewed. In particular, the sdLDL-C subfraction of LDL and the ApoA-1 in large alpha-1 HDL are most informative in conjunction with Lp(a).
    • 本发明提供了用于分析心血管疾病风险的改进方法。 根据本发明,考虑LDL和HDL亚组分以及Lp(a)的算法在预测CVD与包括标准危险因素的标准测定相比提供了显着的改进。 本发明的方法包括除了Lp(a)之外还测量LDL和HDL亚组分,而不参考诸如CRP,总胆固醇,体重指数,体重,甘油三酸酯等的标准危险因素测量。 令人意想的是,仅针对LDL和HDL亚分数和Lp(a)的算法对于CVD风险来说将比对所审查标记方面更为全面的测量更具信息。 特别地,LDL和ApoA-1在大α-1 HDL中的sdLDL-C亚分类与Lp(a)结合是最有说服力的。
