Information System for Doping Control
Proceedings of the 9th International Joint Conference on Biomedical Engineering Systems and Technologies, 2016It is apparent that regulators, sponsors, athletes and sports organizations have become more and more concerned about doping control. Despite the investments made in the past few years, recent studies show that Brazil´s sports federations have not systematized the doping control process nor have they yet dealt satisfactorily with problems to do with ...

Controllable N-Doping of Graphene
Nano Letters, 2010Opening and tuning an energy gap in graphene are central to many electronic applications of graphene. Here we report N-doped graphene obtained by NH3 annealing after N(+)-ion irradiation of graphene samples. First, the evolution of the graphene microstructure was investigated following N(+)-ion irradiation at different fluences using Raman spectroscopy,

Doping Control of Ranitidine in Horses
Drug Testing and AnalysisABSTRACT Ranitidine is a histamine H 2 ‐receptor antagonist commonly used to treat gastric ulceration in horses. The author's laboratory conducted a study some years ago in the early 2000s on its metabolism as well as its urinary elimination profile in two geldings. With the

History of Doping and Doping Control
2009Although attempts to enhance athletic performance are probably much older, the word “doping” was first mentioned in 1889 in an English dictionary. It described originally a mixed remedy containing opium, which was used to “dope” horses. “Dope” was a spirit prepared from the residues of grapes, which Zulu warriors used as a “stimulant” at fights and ...

Doping Control in Sports Medicine
Therapeutic Drug Monitoring, 1996Doping control has become one of the strongest measures to reduce the impact of doping in sports. The rationale for doping control is based on the need to maintain both ethical and medical principles. Among the banned pharmacological substances, the most relevant to sports medicine are anabolic agents, stimulants, narcotic, peptide hormones, diuretics,

Effect of Doping Control on Weightlifting Performance
International Journal of Sports Medicine, 1987The results of participants in Junior World Championships of weight lifting were compared between the years 1978 and 1981 and also between 1981 and 1984. In contrast to a significant improvement of athletic performance which occurred between 1978 and 1981, no significant change was seen between 1981 and 1984.

Detection of the misuse of steroids in doping control
The Journal of Steroid Biochemistry and Molecular Biology, 2010The list of prohibited substances of the World Anti-Doping Agency (WADA) classifies the administration of several steroids in sports as doping. Their analysis is generally performed using urine specimen as matrix. Lots of the steroids are extensively metabolised in the human body.

Controlled cobalt doping of magnetosomes in vivo
Nature Nanotechnology, 2008Magnetotactic bacteria biomineralize iron into magnetite (Fe3O4) nanoparticles that are surrounded by lipid vesicles. These 'magnetosomes' have considerable potential for use in bio- and nanotechnological applications because of their narrow size and shape distribution and inherent biocompatibility.

Control of the Weak Phosphorus Doping in Polysilicon
Materials Science Forum, 2005The optical and electrical properties of undoped and low doped polycrystalline silicon films deposited by LPCVD technique are analysed. Photothermal deflexion spectroscopy, and electrical conductivity in the temperature range 50- 475 K are used. The effect of low phosphorus doping on the density of defects, electrical parameters and hopping conduction ...
