The purpose of this was to determine the prevalence of using the anabolic androgenic steroid (AAS) included knowledge, attitude, frequency of session training a week, side-effect, level of education relative to the AAS.370 body builder who had exercise program at least once a week regularly over the two month period in Hamadan city, participated voluntarily in this study. 71 (19/2%) of 370 su...
In hamsters, adolescent anabolic-androgenic steroid (AAS) exposure facilitates offensive aggression, in part by altering the development and activity of anterior hypothalamic arginine vasopressin (AH-AVP). This study assessed whether these effects were lasting by examining aggression and AH-AVP during AAS withdrawal. Adolescent hamsters administered AAS were tested as adults for aggression at 1...

BACKGROUND Anabolic-androgenic steroids (AAS) abuse by the athletes has dramatically increased during the recent decades. These substances might increase the skin lipids and enhance the cutaneous microbial proliferation. OBJECTIVES The current study aimed to investigate the potential side effects of AAS on the bacterial microflora colonization of the bodybuilders` skin. PATIENTS AND METHODS...
Laboratory red blood cell (RBC) measurements are clinically important, heritable and differ among ethnic groups. To identify genetic variants that contribute to RBC phenotypes in African Americans (AAs), we conducted a genome-wide association study in up to ~16 500 AAs. The alpha-globin locus on chromosome 16pter [lead SNP rs13335629 in ITFG3 gene; P < 1E-13 for hemoglobin (Hgb), RBC count, mea...
BACKGROUND Anabolic androgenic steroids (AAS) are testosterone derivatives used by athletes and recreational users to improve athletic performance and/or enhance appearance. Anabolic androgenic steroids use may have serious and potentially irreversible adverse effects on different organs and systems, including the reproductive system. OBJECTIVE This systematic review and meta-analysis aimed t...
OBJECTIVES To find the relationship between anabolic androgenic steroids (AAS) using and QT interval in athletes. METHODS Between January 1, 2005 and May 31, 2007, we examined QTc interval duration in 165 consecutive male professional bodybuilders [age: 32.1 +/- 4.6 years]. Of these, 79 were AAS users. The control group included 90 sedentary age and gender matched subjects [none of them were ...
In silico functional profiling of human disease-associated and polymorphic amino acid substitutions.
An important challenge in translational bioinformatics is to understand how genetic variation gives rise to molecular changes at the protein level that can precipitate both monogenic and complex disease. To this end, we compiled datasets of human disease-associated amino acid substitutions (AAS) in the contexts of inherited monogenic disease, complex disease, functional polymorphisms with no kn...
BACKGROUND To our knowledge, there has never been a systematic review and synthesis of the qualitative literature on the trajectory and aetiology of nonmedical anabolic-androgenic steroid (AAS) use. METHODS We systematically reviewed and synthesized qualitative literature gathered from searches in PsycINFO, PubMed, ISI Web of Science, Google Scholar, and reference lists of relevant literature...
For a long time D-enantiomers of proteinogenic L-amino acids were assumed to be physiologically irrelevant for plants. But there is growing evidence that D-amino acids (D-AAs) also fulfil important physiological functions in these organisms. However, the knowledge about the metabolic fate of D-AAs in plants is still scarce and more information about it is needed. To close this gap we establishe...
