What are the risk factors associated with damage from CMV? That is, what is the cause that will cause damage during or after pregnancy?
Discuss: a. What is ionizing radiation? b. Three possible effects of exposure of ionizing radiation on living cells. c. Two factors that determine the severity of ionizing radiation.
4. What factors are required to estimate the genetically significant dose of an ionizing electromagnetic radiation such as X-rays or gamma rays? 5. What is the difference between the direct versus the indirect effects of radiation damage to biological target molecules? What is the most important biologic target molecule? 6. Using the calculation examples given in your chapter reading, estimate thc cntrance skin exposure for a PA chest X-ray image conducted at 120 kVp/2 mAs. 7. What four (4) factors...
. Describe the differences between ionizing and non-ionizing radiation. What are the uses of each? What factors influence the effectiveness of antimicrobial treatments:
Much of the biological damage caused by ionizing radiation results from interactions with water. Upon striking water radiation will remove an electron from water, forming H2O+. Reaction of H2O+ with a molecule of water would produce what two species, one of which is highly reactive and damaging to tissue? Draw the reactants, and think how they could react to guide you in answering this question. hydroxide ion and hydronium ion H2(g) and hydroxide ion H2(g) and hydroxyl radical hydronium ion...
Discuss the mechanisms of DNA damage induced by sparsely (low LET) ionizing radiation (e.g., x-rays and -rays) via indirect damage by OH radicals.
discuss the risk and benefits to society associated with the use of devices that produce radiation ionizing and nonionzing radiation, including examples and how each is measured.
What are risk factors associated with adolescent and advanced-age pregnancy?
Ionizing radiation and oxidative damage can cause DNA double-strand breaks. A. True. B False Nucleotide Excision Repair involves recognition of distortions in the DNA double helix rather than specific base changes. A. True. B False Homologous recombination does not occur in prokaryotic cells. A. True. B False Many chemotherapeutic agents are paradoxically DNA damaging agents A. True. B False Meiot.c recombination starts with, double-strand break caused by errors In DNA replication A. True. B False ONA replication origins are typically...
7. Within the cell the most important critical target molecule for producing radiation damage that is lethal or mutagenic to cells is 8 & 9.For any type of imaging using ionizing forms of radiation, in general as the speed of image reception and diagnostic quality of the image necessitating a balance be maintained between exposure and diagnostic quality increases the amount of radiation exposure requirements. Act of 1990 requires the reporting of accidents due to malfunction from 10. The FDA...
