INTRODUCTION Dietary protein amount and source, hypertrophy resistance training (RT) and anabolicandrogenic steroids (AAS) may affect body weight and plasma and hepatic lipid profile. MATERIAL AND METHODS 157 adult male Wistar rats were randomly distributed in 16 experimental groups resulting in: normal-protein (NP) or high-protein (HP) diets, whey or soy-protein diets, with or without RT and...

Due to the new radio architecture of Active Antenna System (AAS), the LTE BS equipped with AAS will have more flexible RF planning than that equipped with passive antenna. However, the new RF characteristic of AAS will have potential impacts on the existing BS RF requirements, which is imperative to be evaluated. In this paper, general antenna pattern and spatial Adjacent Channel Leakage Ratio ...

Anabolic androgenic steroid (AAS) use increased dramatically among adolescent males. This review focuses on studies using animal models of AAS exposure during adolescence which is a hormonally sensitive developmental period. AAS exposure during this critical period has wide-ranging consequences, including increased dendritic spine density, altered brain serotonin levels and escalated aggression...

Anabolic steroid-induced hypogonadism (ASIH) is the functional incompetence of the testes with subnormal or impaired production of testosterone and/or spermatozoa due to administration of androgens or anabolic steroids. Anabolic-androgenic steroid (AAS), both prescription and nonprescription, use is a cause of ASIH. Current AAS use includes prescribing for wasting associated conditions. Nonpres...

Background: Although illicit anabolic-androgenic steroid (AAS) use is widespread, the cardiac effects of long-term AAS use remain inadequately characterized. We compared cardiac parameters in weightlifters reporting long-term AAS use to those in otherwise similar weightlifters without prior AAS exposure. Methods and Results: We performed 2-dimensional, tissue-Doppler, and speckle-tracking echoc...

Anabolic androgenic steroids (AAS) are misused to a high extent in sports by athletes to improve their physical performance. Sports federations consider the use of these drugs in sports as doping. The misuse of AAS is controlled by detection of the parent AAS (when excreted into urine) and (or) their metabolites in urine of athletes. I present a review of the metabolism of AAS. Testosterone is ...

Effects of L-ascorbate 2-sulfate (AAS) on lipid metabolism and on pathological changes of aorta and visceral organs were investigated in cholesterol fed rabbits, with ascorbic acid (AA) and clofibrate (CPIB) as reference compounds. Administration of AAS (300 and 150 mg/kg) inhibited an increase in the levels of serum total cholesterol, free cholesterol, triglycerides and phospholipids caused by...

OBJECTIVE To examine levels of C reactive protein in users of anabolic androgenic steroids (AAS) compared with age matched control groups consisting of AAS using (but abstinent)/resistance trained and non-drug using/sedentary controls. METHOD Subjects included AAS using bodybuilders (n = 10); bodybuilders who denied AAS use (n = 10); sedentary controls (n = 8). Venous blood was sampled, from ...

Tumor cells have an increased nutritional demand for amino acids (AAs) to satisfy their rapid proliferation. Positron-emitting nuclide labeled AAs are interesting probes and are of great importance for imaging tumors using positron emission tomography (PET). Carbon-11 and fluorine-18 labeled AAs include the [1-11C] AAs, labeling alpha-C- AAs, the branched-chain of AAs and N-substituted carbon-1...

To determine the in vivo effect of amino acids (AAs) alone or in combination with insulin on splanchnic and muscle protein dynamics, we infused stable isotope tracers of AAs in 36 healthy subjects and sampled from femoral artery and vein and hepatic vein. The subjects were randomized into six groups and were studied at baseline and during infusions of saline (group 1), insulin (0.5 mU. kg(-1). ...
