Frequency and stability of populations of CD4+ and CD4+CD25+Foxp3+CD127lo Treg in healthy adults defined by cytometry using monoclonal antibodies to T cell associated molecules

open access: yesCytometry Part B: Clinical Cytometry, EarlyView.
Abstract Monitoring subpopulations of CD4+ T cells in blood, especially regulatory CD4+CD25+Foxp3+CD127loT cells, has the potential to identify tolerance to transplants and defects that cause autoimmunity. CD45RA is expressed by naïve/resting CD4+, not by activated cells.

β‐Hydroxy β‐Methyl Butyric Acid (HMB) and Its Potential Doping Relevance: A Pilot Study on Its Urinary Excretion Profile

open access: yesDrug Testing and Analysis, EarlyView.
β‐hydroxy β‐methyl butyric acid (HMB), either as the free acid or in the form of its calcium salt, is a component of several dietary supplements marketed to enhance sports performance. We investigated the urinary excretion profile of HMB, also assessing the endogenous reference ranges of HMB in human urine samples from healthy volunteers (n = 20). Data

Trends in the Detection of Erythropoietin Receptor Agonists (ERAs) in Anti‐Doping: An Analysis of Recent Adverse Analytical Findings (AAFs)

open access: yesDrug Testing and Analysis, EarlyView.
Trends in adverse analytical findings (AAFs) for erythropoietin Receptor Agonist (ERAs) we examined to assess the impact of ERA testing and detection on athlete behavior. It was observed that the largest fraction of ERA AAFs occurs on the first sample ever taken from an athlete (43.2%), and that the ERA AAFs rates decline steadily as athletes continue ...
