  Phantoms for Cross-Calibration of Dual Energy X-ray Absorptiometry Measurements in Infants

  摘要：

  Objective: To test the suitability of phantoms to cross-calibrate body composition measurements in small subjects among different dual energy X-ray absorptiometry (DXA) instruments.Methods: A set of four phantoms with total weights 1520g, 3140g, 4650g and 7490g were made with low cost and easily available materials. Each phantom was made from assembling polyethylene bottles (100 to 1000 mL) filled with either pure olive oil or electrolyte solution in different combinations, and borosilicate tubes (3 and 5 mL) and flexible polypropylene tubing filled with calcium carbonate. Triplicate measurements of each of the four phantoms were performed with three pencil beam densitometers made by the same manufacturer (Hologic Inc., Waltham, MA): two QDR 2000 (University of Liege, Liege, Belgium, and Wayne State University, Detroit, Michigan) and a QDR1500 (University Children's Hospital, Greifswald, Germany) using infant whole body-scanning mode and analyzed with software V5.73P.Results: DXA measured total weight, or bone, lean and fat masses, from one center were highly predictive of DXA measurements from the other centers with an adjusted r(2) of 0.94 to 1.00, p < 0.001. This was the case whether the measurements from single scan or from average of triplicate scans were used in the analysis.Conclusions: Systematic corrections, in the form of linear transformations, are possible to allow comparison of clinical data generated from different centers. Different size phantoms can be made to accommodate the varying range of weights and body composition of study subjects.

  preferentially as the dianion ([M – 2H]2–) with a small contribution of the monoanion ([M – H]−). Product ion spectra generated from the [M – 2H]2– precursor ions were dominated by the loss of HSO4– to generate two product ions, that is, the ion at m/z 97 (HSO4–) and the ion corresponding to the remaining monosulfate fragment. Other product ions were found to be specific for some structures. As an example, the

  II期代谢物的非靶向检测是研究生物系统中药物代谢的关键问题。灵敏且选择性的质谱（MS）技术与超高效液相色谱（UHPLC）系统相结合是最有效的方法。在这项研究中，我们使用三重四极杆仪器评估了针对双硫酸盐代谢物的非目标检测的不同质谱方法。合成了23种甾体代谢物的双硫酸盐，并对其MS行为进行了全面研究。双硫酸盐优先离子化为二价阴离子（[M – 2H] 2–），而单阴离子（[M – H] -）的贡献很小。从[M – 2H] 2 –前体离子产生的产物离子光谱主要由HSO的损失决定4 –生成两个产物离子，即m / z 97处的离子（HSO 4 –）和对应于其余单硫酸盐片段的离子。发现其他产物离子对某些结构具有特异性。例如，发现[CH 3 + SO 3 ] -的损失对于与硫酸盐相邻的几种不饱和化合物很重要。根据双硫酸盐代谢物的常见行为，对两种选择方案进行了非靶向检测双硫酸盐代谢物的评估（i）使用m /

  These metabolites have not been studied in depth for steroids and could be interesting markers for doping control. The aim of the present work was to study the ionization and collision-induced dissociation of steroid bisglucuronides to be able to develop mass spectrometric analytical strategies for their detection in urine samples after AAS administration. Because steroid bisglucuronides are not commercially

  对类固醇代谢的研究对于提高在运动药物测试中滥用的合成代谢雄激素类固醇（AASs）的检测能力至关重要。在人体中，葡萄糖醛酸偶联物是AAS中最丰富的II期代谢产物。双葡糖醛酸化是在同一分子上两个分离的官能团与葡糖醛酸共轭的反应。这些代谢物尚未深入研究类固醇，可能是兴奋剂控制的有趣标志。本工作的目的是研究类固醇双葡糖醛酸苷的离子化和碰撞诱导的解离，以便能够开发质谱分析策略，以便在使用AAS后在尿液样品中检测它们。由于类固醇bisglucuronides不可商购，定性合成了其中的19种化合物，以研究其质谱行为。Bisglucuronides在正离子模式下离子化为[M + NH4] +，在负离子模式下离子化为[MH]-和[M-2H] 2-。正离子模式下甾体双葡糖醛酸苷的最特异产物离子是由387和405 Da的中性损失引起的（对应于[M + NH4 -NH3 -2gluc-H2 O] +和[M + NH4
