In addition to individual education, Brunton assists educate her nurse co-workers. She is a normal loudspeaker at ASTRO nurse meetings and also local Oncology Nursing Culture events. For her presentation, ‘Mucositis – Patient Pain or Nurse’s Bain,’ at ASTRO’s Annual Meeting in 2005, Brunton received the best evaluation ratings within ASTRO for that calendar year. ‘Nursing can be an integral area of the radiation oncology treatment group, ensuring that patients receive the best, safest & most compassionate care because they cope with tumor. Elizabeth Brunton is a wonderful example of radiation oncology nursing,’ Anthony Zietman, M.D., ASTRO president, said.Like the plastic material aglets at the ends of shoe strings, telomeres are regions of the chromosome that keep carefully the DNA from fraying at the ends. Steadily, telomeres erode, a trait which has developed to enforce a cell’s mortality: a cell can only grow and divide therefore often before its DNA becomes as well unstable. This instability happens when telomeres shorten below a crucial threshold. In cancers, the telomere structures are managed but they require capping proteins such as A1 and A2 to be able to permit cell immortality. In lots of cancers, the genes that encode A1 and A2 are over-expressed, leading to an overabundance of the proteins and, as a result, longer-lasting telomeres.
