Fast IRMS screening of pseudoendogenous steroids in doping analyses

Biochemistry and physiology of anabolic androgenic steroids doping.

Anabolic Androgenic Steroids (AASs) are chemical and pharmacological derivatives of the male hormone testosterone which are widely used for increasing burst and sprinting activities in sports. Although AASs are thought to be transversal to the plurality of sports disciplines, they are principally misused by bodybuilders, weightlifters, shot, hammer, discus or javelin throwers, rugby and America...

The application of carbon isotope ratio mass spectrometry to doping control.

The administration of synthetic steroid copies is one of the most important issues facing sports. Doping control laboratories accredited by the World Anti-Doping Agency (WADA) require methods of analysis that allow endogenous steroids to be distinguished from their synthetic analogs in urine. The ability to measure isotope distribution at natural abundance with high accuracy and precision has i...

A fast screening method for the detection of the abuse of hemoglobin-based oxygen carriers (HBOCs) in doping control.

Artificial oxygen carriers (AOCs) can be abused by the athletes to improve their aerobic capacity. The AOCs produce a performance enhancing effect, especially in endurance sports. This article presents a method for the rapid screening of hemoglobin-based oxygen carriers (HBOCs) in blood samples. Common screening tests to reveal HBOC misuse by athletes are based on colorimetric detection since H...

Seroflocculating Steroids. X. the Screening Method.

I N A PREVIOUS REPORT (1), a postulate based on chemical concepts was described which forms the basis of a study of certain steroids possessing seroflocculating properties. The primary objective of the research is the uncovering of a reagent to assist in the diagnosis of disease, perhaps for types of cancer. Secondarily, if that goal is not reached, a reagent suitable for use in a health cleara...
