In vitro irradiation system for radiobiological experiments
BACKGROUND Although two-dimensional (2-D) monolayer cell cultures provide important information on basic tumor biology and radiobiology, they are not representative of the complexity of three-dimensional (3-D) solid tumors. In particular, new models reproducing clinical conditions as closely as possible are needed for radiobiological studies to provide information that can be translated from be...
متن کاملAn irradiation facility with a horizontal beam for radiobiological studies.
A facility with a horizontal beam for radiobiological experiments with heavy ions has been designed and constructed at the Heavy Ion Laboratory in Warsaw University. The facility is optimal to investigate the radiobiological effects of charged heavy particles on a cellular or molecular level as in the region of the Bragg peak.
متن کاملRadiobiological principles in intravascular irradiation.
BACKGROUND There is wide interest in the use of intravascular irradiation to control restenosis following balloon angioplasty. Part of the mechanism of restenosis appears to be the proliferation of smooth muscle cells (SMCs), triggered to divide by the damage caused by the angioplasty, and this proliferation can be inhibited by irradiation with y-rays or beta-rays. METHODS In vitro data for t...
متن کاملAlpha-particle fluence in radiobiological experiments
Two methods were proposed for determining alpha-particle fluence for radiobiological experiments. The first involved calculating the probabilities of hitting the target for alpha particles emitted from a source through Monte Carlo simulations, which when multiplied by the activity of the source gave the fluence at the target. The second relied on the number of chemically etched alpha-particle t...
متن کاملEnhanced radiobiological effects at the distal end of a clinical proton beam: in vitro study
In the clinic, the relative biological effectiveness (RBE) value of 1.1 has usually been used in relation to the whole depth of the spread-out Bragg-peak (SOBP) of proton beams. The aim of this study was to confirm the actual biological effect in the SOBP at the very distal end of clinical proton beams using an in vitro cell system. A human salivary gland tumor cell line, HSG, was irradiated wi...
