Adriamycin resistance and radiation response
International Journal of Radiation Oncology*Biology*Physics, 1979Abstract Mammalian cells (V79) in culture developed resistance to Adriamycin during continuous exposure to low levels of drug. This resistance was accompanied by change in X-ray survival properties which, in turn depended upon the isolation of subpopulations from resistant sub lines.

Radiation-Resisted Shock Waves
The Physics of Fluids, 1962Using a gray-gas quasi-equilibrium theory to describe the radiation effects, the basic integro-differential equation for the one-dimensional flow of a radiating gas is reduced to a nonlinear differential equation by approximating to the radiation absorption functions.

Radiation Resistant Microorganisms
2023 Starting from its formation as a cosmic particle, the earth is exposed to various types of radiation. With gradual cooling and environmental modifications, it started supporting life, first in the form of viruses and bacteria. So, radiation-resistant microorganisms are thought to be among the Earth’s ancient life forms.

Oncogenic Basis of Radiation Resistance
1993Publisher Summary Oncogenes play an important role in the regulation of cellular resistance to ionizing radiation. This chapter reviews some of that evidence and attempt to formulate the themes underlying the oncogenic basis of radiation resistance.

Mechanisms of Resistance to Radiation
2012Radiotherapy is a very effective treatment for achieving local tumor control in breast cancer. However, intrinsic tumor cell radioresistance is a significant clinical problem that limits the results of the treatment. Chemotherapeutics that could specifically sensitize tumors to radiation would greatly increase the ability to deliver higher doses while ...

Positive radiation resists are required for submicrometer lithography using high-energy (10–200 keV) X-ray, ion, and electron beams. Since the resolution of an exposure process is limited by the wavelength of forward and, moreover, backscat-tered radiation, high-energy rays of atom-size wavelengths are capable of resolution to 50 A (Fig.

Radiation-resistant optical glasses
SPIE Proceedings, 1991Hostile environments created by short wavelength electromagnetic radiation (UV, X-ray and gamma-radiation) or from particle fluxes (alpha-particles, beta-particles, protons, and neutrons), can produce discoloration within optical glasses. The associated loss in transmission is detrimental to the performance of any optical system and must be eliminated ...

[Overcoming of radiation resistances].
Nuklearmedizin. Nuclear medicine, 2011Despite good achievements in prevention and control, cancer is still a leading cause of death worldwide. The development of resistances against conventional treatment modalities is one of the main causes of failure in the treatment of cancer. Radio- and chemotherapies fail frequently due to intrinsic or acquired resistances in apoptotic signalling ...

Radiation Resistant MNOS Memories
IEEE Transactions on Nuclear Science, 1972Three types of memory transistor structures were subjected to gamma, neutron and electron radiation. The survival of stored information as a function of total dose and dose rate was recorded, and in addition, the effect of radiation on the overall writing and storage characteristics of the devices was studied.
