About Anabolic Steroids
Microvesicles - tiny membrane-covered sacs - released from glioblastoma cells contain molecules that may provide data that can guide treatment of the deadly brain tumor. In their report in the December 2008 Nature Cell Biology, which is receiving early online release, Massachusetts General Hospital (MGH) researchers describe finding tumor-associated RNA and proteins in membrane microvesicles called exosomes

Anabolic steroids are chemicals that resemble naturally produced hormones produced in the body. These steroids are widely used by athletes who want to build strong muscles. The anabolic steroids are generally used for certain hormone imbalances, muscle wasting diseases, cancer and endocrine disorders.
Anabolic steroids also have virilizing and androgenic properties, which are related to masculine characteristics. Anabolic steroids resemble sex hormone testosterone, which is found in the body. Anabolic steroids are known to have an impact on the testosterone, which helps in enhancing male characteristics and increase of muscle mass. Once the testosterone level in the blood is increased because of anabolic steroid, it stimulates muscle tissues.
Anabolic steroids are also administered in children who do not have proper growth. These steroids can promote bone growth and increase appetite. Anabolic steroids are also used to treat cancer. It helps in building the damaged muscles or tissues caused by cancer. It treats anemia by building up red blood cells.
Anabolic Steroids are illegal and can be bought only by prescription. If Anabolic steroids are used for a longer period, it can cause more damage to the health. Moreover, these damages may take years to appear.
It has been seen that anabolic steroids can affect the reproductive system. Men who continuously use anabolic steroid may have impotence problems, sperm reduction, and reduced size of testicle. In women, the anabolic steroid can lead to changes in menstrual cycles.
Anabolic steroids also lower the level of high-density lipoproteins or good cholesterol, which results in the increase of low-density lipoproteins or bad cholesterol. This shows that there is an increased risk of cardiovascular disease.
When using anabolic steroids, there is also a possibility of liver tumors.
DHEA is a natural circulating hormone and the body’s production of it decreases with age. Men take DHEA as an over-the-counter supplement because it has been suggested that DHEA can reverse aging or have anabolic effects since it can be metabolized in the body to androgens. Increased consumption of dietary isoflavones is associated with a

Researchers at The Ohio State University Comprehensive Cancer Center have discovered that a molecule implicated in leukemia and lung cancer is also important in muscle repair and in a muscle cancer that strikes mainly children. The study shows that immature muscle cells require the molecule, called miR-29, to become mature, and that the molecule is

The U.S. Food and Drug Administration recently approved the injectable drug degarelix, the first new drug in several years for prostate cancer. Degarelix is intended to treat patients with advanced prostate cancer. It belongs to a class of agents called gonadotropin releasing hormone (GnRH) receptor inhibitors. These agents slow the growth and progression of

There is no cure for spinal muscular atrophy (SMA), a genetic disorder that causes the weakening of muscles and is the leading genetic cause of infant death, but University of Missouri researchers have discovered a new therapeutic target that improves deteriorating skeletal muscle tissue caused by SMA. The new therapy enhanced muscle strength, improved gross

During pregnancy, the muscles of the uterus are relatively inactive. A switch to an activated state capable of strong contractions is therefore essential prior to the onset of labor. Kathleen Martin and colleagues, at Dartmouth Medical School, Lebanon, have now provided new insight into the events that prime the uterine muscles for contraction, something that
