The management of human breast cancer frequently includes radiation therapy as an important intervention, and improvement in the clinical efficacy of radiation is desirable. Overexpression of the HER-2 growth factor receptor occurs in 25-30% of human breast cancers and correlates with poor clinical outcome, including earlier local relapse following conservative surgery accompanied by radiation ...

exposure to radiation from different types of television sets was measured to ascertain the levels of hazards posed to the human biological system. measurement of the annual radiation dose hazards was performed using a halogen-quenched gm tube with thin mica end window having a density of 1.5 mg/cm2, effective window diameter of 0.360 inch and side wall of 0.012 inch thick. the gm tube was plac...

The radiation damage behaviour in 43 datasets of 34 different proteins collected over a year was examined, in order to gauge the reliability of decay metrics in practical situations, and to assess how these datasets, optimized only empirically for decay, would have benefited from the precise and automatic prediction of decay now possible with the programs RADDOSE [Murray, Garman & Ravelli (2004...

introduction: a comparision of cytogenetic methods in the evaluation of occupationally received radiation dose by medical radiation workwrs and a study of adaptive response to subsequent higher radiation exposure in this group.the purpose of this research was to study the effects of two cryoprotectants on viability, motility, morphology and fertilization rate of mouse sperm after freezing-thawi...

We present a reconstruction of the dynamics radiation belts from solar cycles 17 to 24 which allows us study how belt activity has varied between different cycles. The simulations are produced using Versatile Electron Radiation Belt (VERB)-3D code. VERB-3D code incorporate radial, energy, and pitch angle diffusion reproduce belts. Our use historical measurements Kp (available since cycle 17, i....
