Cervical epidural steroid injection
Consider one molecule of an anabolic/androgenic steroid (AAS) in the bloodstream, bound to a molecule of testosterone binding globulin (TeBG). cervical epidural steroid injection Physical-side-effects-of-steroids. A receptor on the outside of the muscle cell will bring the TeBG/AAS into the cell. This process itself stimulates the metabolism of the cell by increasing cyclic AMP, but that is not the major effect of AAS use. Alternatively, the AAS molecule may be free in the bloodstream, not bound to anything. cervical epidural steroid injection Steroid affects. If so, it can easily diffuse into the cell through the cell membrane, rather like water soaking through paper. Next, inside the cell, the molecule of AAS binds to a molecule of androgen receptor (AR), which is inside the cell, not in the cell membrane. The androgen receptor is a very large molecule and is made of about a thousand amino acids. cervical epidural steroid injection How to use steroids. Thus, it is far larger than the molecule of AAS. The AR has a "hinge" region, and can be folded into either of two shapes. When it binds a molecule of AAS, the AR folds at the hinge, and is activated. Think of the AR as being a machine that does nothing unless it is turned on. The AR either has an AAS bound to it, and is thereby switched on; or it does not, and is switched off. There is no intermediate condition that might cause an AAS to give a weak effect - there is no being "halfway folded" at the hinge. The only question is, How long does the AR stay activated before the AAS leaves? The answer, generally, is in the range of a couple of hours. After the AAS leaves, the AR returns to its original state, and is ready to be used again. Since the AR can only be either activated or not activated, it is just as much activated by say a bound molecule of methenolone (from Primobolan) as it is by a bound molecule from any other AAS. This is not to say that differing AAS may give differing results for other reasons. Once a molecule of AAS is bound to the AR, the receptor now travels to the nucleus of the cell, and forms a dimer (pair) with another activated AR. The dimer then binds to certain parts of the DNA, and certain genes then start producing more mRNA.
