Despite the fact that the 3T system looks identical to the 1.5 the similarity does not mean equal site considerations. Frequent injuries in the MRI suite and equipment damage are caused by the introduction of magnetic metals into the magnet room. The active shielding on most new 3T systems does a great job of restraining the magnetic field.
Autophagy is a normal process in which a cell destroys proteins and other substances in its cytoplasm (the fluid inside the cell membrane but outside the nucleus), which may lead to cell death.utophagy is a normal process in which a cell destroys proteins and other substances in its cytoplasm (the fluid inside the cell membrane but outside the nucleus), which may lead to cell death.
In the context of disease, autophagy has been seen as an adaptive response to stress which promotes survival, whereas in other cases it appears to promote cell death and morbidity. In the extreme case of starvation, the breakdown of cellular components promotes cellular survival by maintaining cellular energy levels.utophagy is constantly activated in normal cartilage but it is compromised with age and precedes cartilage cell death and structural damage. These results suggest autophagy is a normal protective process (chondroprotection) in the joint.
