Three instances of radiation necrosis were observed, which were all patients in the comparison groups.
Since mutations of DNA ligase IV account for some instances of radiation hypersensitivity, we are examining further radiosensitive individuals for abnormal DNA ligase IV protein expression.
Despite the widespread occurrence and attractive mechanistic simplicity of adaptive radiations, the evolutionary outcome of an instance of adaptive radiation cannot generally be predicted with any degree of confidence.
The evolutionary outcome of an instance of adaptive radiation cannot generally be predicted because chance (stochastic events) and necessity (deterministic events) contribute to the evolution of diversity.
The datasets allow researchers to make one-to-one comparisons of algorithms in order to solve various instances of the radiation therapy treatment planning problem in intensity modulated radiation therapy (IMRT), including beam angle optimization, volumetric modulated arc therapy and direct aperture optimization.
In Tokyo, for instance, the level of radiation has never reached a point at which it would affect human health.
For instance, the study of radiation use for bone metastasis in Africa suggests an opportunity to reduce the number of daily radiation treatments per patient.
For instance, the risks of radiation are often posed as a major concern, yet in the USA in 2002 there were no deaths from radiation, compared with 66 from lightning, 63 from cataclysmic storm, 31 from earthquake or other earth movements, and 9 from flood.
Different instances of adaptive radiation will yield different niche specialists and different ecological relationships among specialists, despite historical constraints or similarities among selective environments.
This is apparently due, in first instance, to the ability of radiation to interact with EGFR causing receptor activation even in absence of EGF, for instance by TGF α release and EGFR autophosphorylation increase.
