  • On September 25, 1958, Saenger sent a grant proposal entitled "Metabolic Changes in Human following Total Body Radiation" to the Department of Defense, requesting $25,085 to analyze the amino-aciduria levels in the urine of total body irradiated patients. (wikipedia.org)
  • Although they were all cancerous, Dr. Saenger sought patients that were in good nutritional health, and who had not been exposed to previous radiation treatment. (wikipedia.org)
  • citation needed] Unfortunately for some patients, as time passes, people who received radiation therapy may begin experiencing deficits in their learning, memory, and spatial information processing abilities. (wikipedia.org)
  • Therefore, if radiation therapy inhibits neurogenesis in the hippocampus it would lead to the cognitive decline observed in patients who have received this radiation therapy. (wikipedia.org)
  • irradiation
  • X-ray exposure area product, primary and scatter radiation to patient and interventionist and procedure and irradiation time for interventions performed without and with region-of-interest imaging (control and experimental arms, respectively). (clinicaltrials.gov)
  • However, the Advisory Committee on Human Radiation Experiments held that without the DOD funds, Dr. Saenger could not have begun the irradiation tests. (wikipedia.org)
  • David Egilman, a doctor practicing in Massachusetts at the time, criticized the patient selection and irradiation processes in a statement to the Advisory Committee on Human Radiation Experiments, writing that many of the cancers were radio-resistant and could not have been treated effectively without killing the patient.

  • radon
  • Even with collective evidence, it was not until the 1950s, thanks in part to W.F. Bale, that it was accepted by researchers that radon was the major cause of radiation damage to lung tissue in mine workers. (wikipedia.org)

  • exposure to radiation
  • RESULT: A comparison of the recommended borders to the actual boundaries of the radiographs taken show an additional exposure to radiation in all three procedures: 85% of chest radiographs also included the whole abdomen, 64% of abdomen radiographs included both thigh and upper chest and 62% of chest and abdomen radiograph included the thigh.

  • beam
  • NASA considered connecting a Bigelow expandable craft to the ISS for safety, life support, radiation shielding, thermal control and communications verification testing for the next three years," and in December 2012, signed a $17.8 million contract with Bigelow to develop the Bigelow Expandable Activity Module (BEAM), then projected to fly in 2015. (wikipedia.org)
  • proven
  • In animal studies discussed by Monje and Palmer in "Radiation Injury and Neurogenesis", it has been proven that radiation does indeed decrease or arrest neurogenesis altogether in the hippocampus. (wikipedia.org)
  • However it has not been proven whether the apoptosis is a direct result of the radiation itself or if there are other factors that cause neuronal apoptosis, namely changes in the hippocampus micro-environment or damage to the precursor pool. (wikipedia.org)
  • therapy
  • The goal is to be able to develop patient-specific treatment, and kidneys were chosen for prototyping as they're one of the highest-risk organs in radiation therapy and imaging. (odbornecasopisy.cz)
  • citation needed] Dysgeusia, or an alteration in taste perception, is common, especially for those who are receiving concomitant radiation therapy to the neck and mouth area. (wikipedia.org)
  • Radiation therapy can be used to cure care or shrink tumors that are interfering with quality of life. (wikipedia.org)
  • However, the question remains whether radiation therapy results in a complete ablation of the stem cell pool in the hippocampus or whether some stem cells survive. (wikipedia.org)
  • probe
  • In the case of projectional radiography, the probe uses X-ray radiation, which is absorbed at different rates by different tissue types such as bone, muscle and fat. (wikipedia.org)
  • greatly
  • The truth is that the problem of deadly radiation in the atmosphere and in the Pacific Ocean has been greatly exacerbated since March of 2011 because radiation has been accumulating, and continues to accumulate since that day. (blogspot.com)
