  • It's coming: a breathalyzer for anabolic steroids




    Doping hunters from the German Sport University Cologne are developing a completely new type of doping test. The new test does not require sweat, blood, urine, hair or mouth swabs, but will enable doping hunters to detect the use of anabolic steroids and other banned substances by analyzing the breath of athletes. O my.



    Study
    The German biochemist and doping hunter Mario Thevis published a human study in Rapid Communications in Mass Spectrometry, which delivered proof of principle and showed that the detection of banned substances by analyzing breath is possible. In the publication Thevis tells, among other things, that he collected a group of test subjects who used doping substances, and then analyzed their breath with LC/MS/MS.



    The subjects were "either [...] patients using the drugs in question in regular therapeutic settings or [...] individuals participating in elimination studies investigating the same substance classified as doping agents." Thevis needed the subjects to exhale 20 liters or air for his measurements. When a adult exhales, he produces about half a liter or air.



    Results
    Thevis and his colleagues were able to detect meldonium, DMAA, oral-turinabol and pseudoephedrine in the breath of their subjects.











    Conclusion
    "The results of this pilot study and literature data from the field of therapeutic drug monitoring and forensic analyses indicate that drugs of rather different physico-chemical nature are traceable in exhaled breath", the Germans summarize.



    "Consequently, a considerable number of compounds relevant for doping controls could be monitored via exhaled breath sampling in potential future sports drug testing programs that could utilize the non-invasive sample collection approach of exhaled breath."



    "To date, information on analyteconcentrations in exhaled breath, detection times, etc., are still limited to a small number of relevant compounds. Hence, follow-up studies are required to assess the full potential of exhaled breath as an alternative matrix in doping controls, and a considerable expansion of the spectrum of compounds that can be monitored from exhaled breath is needed."



    "This necessitates utmost analytical sensitivity considering the minute amounts of target analytes expected to be eliminated via an athletes' breath."

      Test for doping with YK11



      About five years ago YK11 came on the market: a steroid-like substance developed by Japanese scientists with an anabolic effect. YK11 is a SARM, but also a myostatin inhibitor. It became popular as a research chemical and 'rogue supplement'. German doping hunters from the German Sport University Cologne have developed a doping test for this curious substance.

      Abstract

      Concern has arisen regarding the presence and persistence of trenbolone in the environment. Trenbolone acetate is an anabolic steroid used to promote growth in beef cattle. It is hydrolyzed to the active compound, 17beta-trenbolone (TB), which is also one of the metabolites...

    • Plasma steroid-binding proteins: primary gatekeepers of steroid hormone action.
      by WesleyInman



      Abstract

      Biologically active steroids are transported in the blood by albumin, sex hormone-binding globulin (SHBG), and corticosteroid-binding globulin (CBG). These plasma proteins also regulate the non-protein-bound or 'free' fractions of circulating steroid hormones that are considered to be biologically active; as such, they can be viewed as the 'primary gatekeepers of steroid action'. Albumin binds steroids with limited specificity and low affinity, but its high concentration...

      Transgender Boxer (Female to Male) Patricio Manuel Makes History with First Pro Win


      Los Angeles (AFP) – Transgender boxer Patricio Manuel made history Saturday with a unanimous decision victory over Mexican super-featherweight Hugo Aguilar in Indio, California.

      Manuel, 33, became the first transgender male to fight professionally in the United States.

      “I wouldn’t trade any of it. It was worth everything I went through to get to this point,” Manuel said,
