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.

With this cause of mutation, a decrease in the number of genes occurs due to the deletion of a large section of a chromosome. Deletion can result in a variety of genetic disorders, such as Prader-Willi syndrome, Cri d Chat syndrome, and Angelman's syndrome.ach of these mutations can cause a variety of different diseases and conditions. Read on to learn what these mutations are and what disorders they can cause. slide 1 of 8. The causes of chromosomes mutation occur when there is any change in the arrangement or structure of the chromosomes.
