The athlete's biological passport and indirect markers of blood doping.
Forensic techniques for the evaluation of the evidence, and more particularly Bayesian networks, allow antidoping authorities to take into account firstly the natural variations of indirect markers - through a mathematical formalism based on probabilities - and secondly the complexity due to the multiplicity of causes and confounding effects through a distributed and flexible graphical representation.
Effect on Root Growth of Endogenous and Applied IAA and ABA: A Critical Reexamination.
IAA has a more powerful effect on root elongation than ABA for identical concentrations, according to previous data related to the role of IAA and ABA in the growth and gravireaction of maize roots.

The main effects of exercise on hGH production and the use and effects of rhGH in athletes are discussed, and the most promising method appears to be the direct approach utilising immunoassays.

An overview of the use of anabolic-androgenic steroids in sport and methods used in anti-doping laboratories for their detection in urine, with special emphasis on doping with testosterone, is given.
The athlete biological passport.
The Athlete Biological Passport can also serve as a platform for a Rule of Sport, with the presentation before competition of the ABP to objectively demonstrate that the athlete will participate in a healthy physiological condition that is unaltered by performance-enhancing drugs.
Bayesian detection of abnormal values in longitudinal biomarkers with an application to T/E ratio.
The heightened sensitivity/specificity relation obtained on a large data set shows that longitudinal monitoring of an athlete's steroid profile may be used efficiently to detect the abuse of testosterone and its precursors in sports.
From population- to subject-based limits of T/E ratio to detect testosterone abuse in elite sports.

The findings of the analysis of 75 different nutritional supplements bought through the internet found that seven products contained other hormone substances than indicated on the labels, and two further products contained ephedrine and caffeine without a clear indication on the label.
Monitoring of biological markers indicative of doping: the athlete biological passport
The athlete biological passport (ABP) was recently implemented in anti-doping work and is based on the individual and longitudinal monitoring of haematological or urine markers. These may be…
