  • dose
  • First is that the stem cell dose, measured in nucleated cells/kg body weight, is considerably lower due to the size of the recipient. (knowcancer.com)
  • A single irradiation dose also caused synchronization of thymopoiesis, with a periodic thymocyte differentiation profile persisting for at least 12 mo postirradiation. (jimmunol.org)
  • antigens
  • Immune effector cells such as lymphocytes, macrophages, dendritic cells, natural killer cells (NK Cell), cytotoxic T lymphocytes (CTL), etc., work together to defend the body against cancer by targeting abnormal antigens expressed on the surface of tumor cells. (wikipedia.org)
  • Local irradiation of a tumor nodule may lead to immunogenic forms of tumor cell death and liberation of tumor cell-derived antigens. (wikipedia.org)
  • tumor cells
  • In contrast to the local effect of irradiation on the tumor cells, these cytotoxic T cells circulate through the blood stream and are thus able to destroy remaining tumor cells in distant parts of the body which were not irradiated. (wikipedia.org)
  • involves
  • The process involves sucking out the nucleus of a somatic (body) cell and injecting it into an oocyte that has had its nucleus removed Using an approach based on the protocol outlined by Tachibana et al. (wikipedia.org)
  • primarily
  • Taken together, these data suggest that long-term suppression of thymopoiesis after sublethal irradiation was primarily due to fewer progenitors in the BM combined with reduced potential for T lineage commitment. (jimmunol.org)
  • cells
  • TBI is very effective in killing diseased cells anywhere in the body. (cancernet.co.uk)
  • It is also useful in killing any cancerous cells that have spread to other parts of the body. (wikipedia.org)
  • This process allows the body to replace cells not suitable to new conditions with more suitable new cells. (wikipedia.org)
  • donor
  • This study is being done to learn whether a new method to prevent rejection between the donor immune system and the patient's body is effective. (bioportfolio.com)
  • View
  • One of the units at the Cleveland Clinic was used to construct an image of the body that today would be called a "Scout View", essentially a digital x-ray that was produced by moving the body through the gantry with the x-ray tube stationary. (wikipedia.org)
  • Made
  • In that technique a series of X-ray exposures made from different angles around the body are combined by computer to present a cross-sectional picture on the screen of a cathode-ray tube. (wikipedia.org)
  • fission
  • Three mechanisms for each type of catastrophe were considered: direct irradiation from the fission product cloud, inhalation of the air in the cloud, and rainout from the cloud followed by irradiation from the ground. (unt.edu)
  • Large scale impact events or even the destruction of the parent body can be dated using the 39Ar/40Ar method and the 244Pu fission track method. (wikipedia.org)
  • neutron
  • Its production follows the reaction: 124Xe (n,γ)→ 125mXe(57s)→125I (59,4 d) 124Xe (n,γ)→ 125gXe(19,9h)→125I (59,4 d) The irradiation target is natural xenon gas containing 0.0965% 124Xe, which is the target isotope for making I-125 by neutron capture. (wikipedia.org)
  • Iodine-125 itself has a neutron capture cross section of 900 barns, and consequently during a long irradiation, part of the 125I formed will be converted to 126I, a beta-emitter and positron-emitter with a half-life of 13.1 days, which is not medically useful. (wikipedia.org)
  • high
  • Daxx is uniformly expressed throughout the body, except in the testes and thymus, which have especially high expression of the protein. (wikipedia.org)
  • It was shown that Daxx associates with Pml only when exposed to high oxidative stress or UV-irradiation. (wikipedia.org)
  • Impacts on the parent body are recorded by impact-breccias and high-pressure mineral phases (e.g. coesite, akimotoite, majorite, ringwoodite, stishovite, wadsleyite). (wikipedia.org)
  • generally
  • Gemstones that have been subjected to artificial irradiation generally show no visible evidence of the process, although some diamonds irradiated in an electron beam may show color concentrations around the culet or along the keel line. (wikipedia.org)
  • time
  • On average, sitting in the sun during this time of day for 10 minutes will stimulate the body to make 10,000 units of vitamin D. If you are going to be in the sun longer, it is recommended you use a natural sunscreen to protect yourself from the harmful effects of UV rays (2). (riordanclinic.org)
  • In practice, the most useful irradiation time in the reactor amounts to a few days. (wikipedia.org)
  • sources
  • In topaz, some irradiation sources may produce mixtures of blue and yellow-to-brown colors, so heating is required as an additional procedure to remove the yellowish color. (wikipedia.org)
  • cell
  • The researchers used EL4 cells - a mouse lymphoma cell line - to see if cell proliferation was affected by X-ray irradiation when the cells had been treated by one of the three monoterpenes. (prweb.com)
  • ASK1 will be transported to the nucleus when UV-irradiation is used to treat the cell. (wikipedia.org)
  • surgery
  • The main classes of antimicrobial agents are disinfectants ("nonselective antimicrobials" such as bleach), which kill a wide range of microbes on non-living surfaces to prevent the spread of illness, antiseptics (which are applied to living tissue and help reduce infection during surgery), and antibiotics (which destroy microorganisms within the body). (wikipedia.org)
  • areas
  • Reduced susceptibility to other surgical outcomes obtained after elective irradiation of supradiaphragmatic lymph nodes and distal with proximal areas are also conducted. (bvbdallas.org)
  • function
  • The "Atomic Energy Regulatory and Liability Act of 1968" established the regulatory function and mandate of the PAEC whereas on December 13, 1974, Presidential Decree No. 606 established the PAEC as an independent and autonomous body. (wikipedia.org)
  • point
  • Ion and plasma thrusters commonly used to propel spacecraft can be employed to produce a collimated plasma/ion beam and point it towards the body. (wikipedia.org)
