OBJECTIVE To explore use and attitudes toward drugs and dietary supplements (DS) and knowledge concerning doping in cycling. DESIGN Retrospective cross-sectional study. SETTING Professional cycling. PARTICIPANTS Elite under-23 male cyclists. INTERVENTION Anonymous semistructured questionnaire administered during race periods. MAIN OUTCOME MEASURES Use and attitudes toward DS and drugs...
Background and Purpose: Due to the advertising of new technologies for the use of biochemical resources to enhance muscle mass, doping is interwoven with the development of the modernized organized sport. Different fields of study, such as history, sociology, and psychology investigate doping with their theoretical methods and frameworks. The present study aimed to investigate the psychological...
One of the most challenging topics of ethics in sport is the problem of "doping" by the usage of improper methods and materials of doping. In order to draw a valid conclusion, the paper attempts to evaluate and criticize the pros and conschr('39') evidences of doping taken from internet sites, different papers and Islamic resources. The derived conclusion indicates that despite of bringing abou...
Impact ionization in fully depleted (FD) Silicon On Insulator (SOI) n-Channel MOSFET is investigated as a function of the doping concentration. We have found that impact ionization increases with the decrease in the doping concentration and vice versa. Simulation results obtained from Sentaurus TCAD with the higher doping concentration can control the threshold voltage (Vth). Furthermore we hav...
BACKGROUND Despite the efforts of the World Anti-Doping Agency and national anti-doping agencies at the international level, a relatively low and steady rate of positive doping tests still persists all over the world. Evidence on adolescents using doping substances exists, and the proportion of adolescents engaging in doping practices is small but significant. In relation to the international r...
We review theoretical investigations of high-temperature superconductors which have been performed by density functional theory. The main subject of our study is the Hg-based family of the superconducting cuprates, which demonstrates unusual and still puzzling properties. We show that the first-principles approach is able to describe the effects of chemical doping and pressure on the structur...
BACKGROUND The use of performance enhancing drugs is still a major problem in competitive sports. Even though tennis is not affected by systematic doping, there is lack of scientific evidence on the effect of sanctions on players` career. The aim of this study was to analyze male tennis players' career after a doping sanction. METHODS All doping offences committed by male professional tennis ...
conclusions analysis of codeine to morphine metabolism rate is needed when we are using morphine/codeine ratio to rule out abuse of narcotics. wada should consider analysis for the cyp2d6 alleles (main metabolizer of codeine) in case of including morphine/codeine ratio in future prohibited list. the possibility of ultra-rapid cyp2d6 cannot be ruled out in certain results of morphine/codeine nea...
influence of aluminum, gallium, indium- doping on the boron-nitride nanotubes (bnnts) investigated with density functional theory (dft) and hartreefock (hf) methods. for this purpose, the chemical shift of difference atomic nucleus was studied using the gauge included atomic orbital (giao) approch. in the following, structural parameter values, electrostatic potential, thermodynamic parameters,...
Objective: Despite the prevalence of doping in sport and the need for doping prevention strategies, information about doping awareness among medical professionals is limited. The aim of this pilot study was to investigate the knowledge and attitude of South African pharmacists (Ps) and general practitioners (GPs) towards doping in sports. Methods: An online survey questionnaire was completed by...
