Medical Issues Associated with Anabolic Steroid Use: Are They
Other adverse events generally associated with anabolic steroid use include acne, male pattern baldness, gynecomastia, decreased sperm count, testicular atrophy, impotence, and transient infertility. Acne is one of the more common side effects associated with anabolic steroid administration.
Steroids: Pharmacology, Complications, and Practice Delivery Issues
Background Since their identification nearly 80 years ago, steroids have played a prominent role in the treatment of many disease states. Many of the clinical roles of steroids are related to their potent antiinflammatory and immune-modulating properties. Methods This review summarizes the basic pharmacology, complications, and practice delivery issues regarding steroids. Results Clinically ...
Steroids
STEROIDS is an international research journal devoted to studies on all chemical and biological aspects of steroidal moieties. The journal focuses on both experimental and theoretical studies on the biology, chemistry, biosynthesis, metabolism, molecular biology, physiology and pharmacology of …. View full aims & scope.
Anabolic-androgenic steroids: How do they work and what are the risks?
Anabolic-androgenic steroids (AAS) are a class of natural and synthetic hormones that owe their name to their chemical structure (the steroid nucleus, see Figure 1 ) and the biological effects (anabolic and androgenic) they induce. Anabolic refers to the skeletal muscle-building properties of AAS, whereas androgenic refers to the induction ...
Anabolic-Androgenic Steroid Use in Sports, Health, and Society
Anabolic-androgenic steroid use is advantageous in athletic performance predominantly through enhancements in strength, power, increases in muscle mass, reduced recovery time, and other factors.
The science of steroids
Steroids are complex lipophilic molecules that have many actions in the body to regulate cellular, tissue and organ functions across the life-span. Steroid hormones such as cortisol, aldosterone, estradiol and testosterone are synthesised from cholesterol in specialised endocrine cells in the adrena ….
Revisiting steroidogenesis and its role in immune regulation with the
Historically tools and technologies facilitated scientific discoveries. Steroid hormone research is not an exception. Unfortunately, the dramatic advancement of the field faded this research area ...
The Journal of Steroid Biochemistry and Molecular Biology
The Journal of Steroid Biochemistry and Molecular Biology is devoted to new experimental and theoretical developments in areas related to steroids including vitamin D and lipids. The Journal is interested in functional analyses of signal transduction pathways, impact on molecular …. View full aims & scope.
Anabolic-androgenic steroid use is associated with ...
Previous research has uncovered medical and psychological effects of anabolic-androgenic steroid (AAS) use, but the specific relationship between AAS use and risk-taking behaviors as well as ...
Ecdysteroids as non-conventional anabolic agent: performance ...
Recent studies suggest that the anabolic effect of ecdysterone, a naturally occurring steroid hormone claimed to enhance physical performance, is mediated by estrogen receptor (ER) binding. In comparison with the prohibited anabolic agents (e.g., metandienone and others), ecdysterone revealed to be …
The Effects of Supraphysiologic Doses of Testosterone on Muscle Size
Athletes often take androgenic steroids in an attempt to increase their strength. The efficacy of these substances for this purpose is unsubstantiated, however. We randomly assigned 43 normal men t...
Adverse Effects of Anabolic-Androgenic Steroids: A Literature Review
Anabolic-androgenic steroids (AASs) are a large group of molecules including endogenously produced androgens, such as testosterone, as well as synthetically manufactured derivatives. AAS use is widespread due to their ability to improve muscle growth for aesthetic purposes and athletes' performance, minimizing androgenic effects.
Anabolic Steroid use in Sports and in Physical Activity ...
Anabolic steroids,commonly referred to as anabolic androgenic steroids (AAS), are a family of hormones that comprises testosterone. Exposure to these substances can result in damage to human ...
Steroid use and human performance: Lessons for integrative biologists
Abstract While recent studies have begun to address how hormones mediate whole-animal performance traits, the field conspicuously lags behind research conducted on humans. Recent studies of human steroid use have revealed that steroid use increases muscle cross-sectional area and mass, largely due to increases in protein synthesis, and muscle fiber hypertrophy attributable to an increased ...
Anabolic-androgenic steroids: How do they work and what ...
Anabolic-androgenic steroids (AAS) are a class of hormones that are widely abused for their muscle-building and strength-increasing properties in high, nontherapeutic, dosages. This review ...
Generating evidence on the use of Image and performance enhancing drugs
Background The use of anabolic androgenic steroids (AAS) and associated image and performance enhancing drugs (IPEDs) is now a global phenomenon. There is a need to develop evidence to support the development of interventions to prevent the commencement of use, to minimise the potential harms or to support those in their cessation of use. While the United Kingdom (UK) is no exception to this ...
Full article: Anabolic androgenic steroid use population size
Harms associated with anabolic androgenic steroids (AAS) use are well-established and a public health concern. Robust estimates of the numbers using AAS are needed to inform responses, however, in ...
Research Paper Anabolic-androgenic steroid use among women
Background Female users of anabolic-androgenic steroids (AAS) are at risk of developing masculinizing side effects. This study explores how the development of masculinizing effects has been experienced and processed by women with current or previous AAS use.
Systemic steroids and bronchopulmonary dysplasia: a systematic ...
It is unclear if systemic steroids decrease the risk of Bronchopulmonary Dysplasia (BPD) while increasing the risk of neurodevelopmental impairment (NDI). Conduct a systematic review of randomized ...
Steroid Hormones and Receptors in Health and Disease
Steroid hormone effects have been reported for almost 140 years 1 - 3. Research over the past 50 years has led to the discovery of steroid hormone receptors that act via both genomic and nongenomic ("rapid") mechanisms. Steroids are involved in physiology and disease, mediating endocrine, cardiovascular, and reproductive functions and ...
Anabolic steroids
The term "anabolic steroids" refers to testosterone derivatives that are used either clinically or by athletes for their anabolic properties. However, scientists have questioned the anabolic effects of testosterone and its derivatives in normal men for decades. Most scientists concluded that anabolic steroids do not increase muscle size or ...
Contextualization of a Shifting Perspective Regarding the Steroid Era
Recommended future research on these and similar topics should include tracing of the changes in sentiment regarding the steroid era, continued review of the perils and pitfalls of steroid use, as well as the consistent review of rules, regulations, policies, and procedures regarding steroids and performance enhancing drugs.
Steroid and the brain: 50 years of research, conceptual shifts and the
A colossal amount of progress has been made since these seminal discoveries of steroids. The study of hormone action has become an entire field of fundamental and applied research called Endocrinology (covering of course also actions of non-steroid hormones that are not covered here).
Long-Term Use of Oral Corticosteroids and Safety Outcomes for Patients
