The surgical instrument technician sterilizes and prepares instruments for use in surgeries. Surgical instrument techs are often responsible for sterilization and preparation of instruments and other areas of an operating room.A surgical instrument technician may be considered part of the surgical team.he required education for surgical instrument technicians in most facilities is a minimum of a two-year degree in an allied health program specializing in surgical or biomedical procedures.
DNA Damage: Causes and Effects. The most significant consequence of oxidative stress in the body is thought to be damage to DNA. DNA may be modified in a variety of ways, which can ultimately lead to mutations and genomic instability.This could result in the development of a variety of cancers including colon, breast, and prostate.Here we discuss the various types of damage to DNA, including oxidative damage, hydrolytic damage, DNA strand breaks, and others. Oxidative DNA damage refers to the oxidation of specific bases.8-hydroxydeoxyguanosine (8-OHdG) is the most common marker for oxidative DNA damage and can be measured in virtually any species. It is formed and enhanced most often by chemical carcinogens.A similar oxidative damage can occur in RNA with the formation of 8-OHG (8-hydroxyguanosine) , which has been implicated in various neurological disorders. Hydrolytic DNA damage involves deamination or the total removal of individual bases.t is formed and enhanced most often by chemical carcinogens.

This cause of mutation occurs when a piece of one chromosome is transferred to a non-homologous chromosome. The two chromosomes, that are often reciprocal, swap segments with each other. This genetic mutation is often responsible for chronic myelogenous leukemia.his cause of mutation occurs when a piece of one chromosome is transferred to a non-homologous chromosome.
