Autor: Jonas Bergquist, A. Wayne Meikle, Julius Hreinsson, Kjell Wånggren, Alan L. Rockwood, Tord Naessen, Mark M. Kushnir

Publikováno v: The Journal of Steroid Biochemistry and Molecular Biology. 162:126-133

Steroid concentrations in stimulated follicular fluid (sFF) samples have been linked to the quality of oocytes used in IVF treatments. Most of the published studies focused on evaluating the association of the IVF outcomes with only a few of the ster

Performance enhancement in the measurement of 5 endogenous steroids by LC–MS/MS combined with differential ion mobility spectrometry

Autor: Mark M. Kushnir, A. Wayne Meikle, Julie A. Ray, Alan L. Rockwood, Richard A. Yost

Publikováno v: Clinica Chimica Acta. 438:330-336

Challenges for steroid analysis by LC-MS/MS include low ionization efficiency, endogenous isobars with similar fragmentation patterns and chromatographic retention. Differential ion mobility spectrometry (DMS) provides an additional degree of separat

Measurement of Thyroglobulin by Liquid Chromatography–Tandem Mass Spectrometry in Serum and Plasma in the Presence of Antithyroglobulin Autoantibodies

Autor: Alan L. Rockwood, A. Wayne Meikle, William L. Roberts, Andrew N. Hoofnagle, Dev Abraham, Mark M. Kushnir

Publikováno v: Clinical Chemistry. 59:982-990

BACKGROUND Measurement of serum thyroglobulin (Tg) is used to monitor patients after treatment for differentiated thyroid carcinoma (TC). Difficulty in using Tg as a biomarker of the recurrence of TC in many patients stems from the presence of endoge

An exploratory study Evaluating the impact of opioid and non-opioid pain medications on serum/plasma free testosterone and free estradiol concentrations

Autor: Julie A, Ray, Mark M, Kushnir, A Wayne, Meikle, Jill E, Sindt, Frederick G, Strathmann

Publikováno v: Drug testing and analysis. 9(10)

Chronic use of opioid medications has been reported to cause altered sexual function. It is not known if non-opioid pain medications have similar effects. Assessment of this effect through the measurement of concentrations of free hormones is limited

High Sensitivity Measurement of Pancreatic Polypeptide and Its Variant in Serum and Plasma by LC-MS/MS

Autor: Hernando Escobar, Mark M. Kushnir, Alan L. Rockwood, A. Wayne Meikle

Publikováno v: Clinical Applications of Mass Spectrometry in Biomolecular Analysis ISBN: 9781493931811

Aliquots of serum or plasma samples are combined with stable isotope labeled internal standard. Pancreatic polypeptide (PP) and its truncated variant PP3-36 are enriched by incubation with anti-PP antibody conjugated to magnetic beads. Peptides are e

Direct Measurement of Free Estradiol in Human Serum and Plasma by Equilibrium Dialysis-Liquid Chromatography-Tandem Mass Spectrometry

Autor: Mark M. Kushnir, Alan L. Rockwood, Julie A. Ray, A. Wayne Meikle

Publikováno v: Clinical Applications of Mass Spectrometry in Biomolecular Analysis ISBN: 9781493931811

We describe a direct method of measurement of free estradiol using equilibrium dialysis followed by liquid chromatography-tandem mass spectrometry (LC-MS/MS). Serum aliquots and internal standards are extracted by liquid-liquid extraction using methy

Obesity and Male Infertility: A Practical Approach

Autor: Mark Gibson, C. Matthew Peterson, Ahmad O. Hammoud, Douglas T. Carrell, A. Wayne Meikle, Leonardo Oliveira Reis

Publikováno v: Seminars in Reproductive Medicine. 30:486-495

Obesity in men is associated with infertility in numerous studies, and the temporal trend for a decline in semen parameters parallels the increasing prevalence of obesity in the developed world. In addition to impaired semen quality, fertility among

Association of 25-hydroxy-vitamin D levels with semen and hormonal parameters

Autor: C. Matthew Peterson, A. Wayne Meikle, Joseph B. Stanford, Douglas T. Carrell, Ahmad O. Hammoud, Mark Gibson

Publikováno v: Asian Journal of Andrology

Vitamin D levels have been linked to various health outcomes including reproductive disorders. The purpose of this study was to explore the association between serum vitamin D level (25-hydroxy-vitamin D, or 25OHD) and semen and hormonal parameters.
