The presence of hypoxic tumor cells is known to be an important cause of radiation treatment resistance in vivo. The ability to predict the presence and extent of hypoxic cells in individual tumors would allow the addition of specific "antihypoxia"-based treatment regimes. Hypoxia can be monitored by measuring the binding of 2-nitroimidazoles. We have tested the hypothesis that binding of EF5, ...

We cloned the gene (c1) which encodes the repressor of vegetative function of Pseudomonas aeruginosa bacteriophage D3. The cloned gene was shown to inhibit plating of D3 and the induction of D3 lysogens by UV irradiation. The efficiency of plating and prophage induction of the heteroimmune P. aeruginosa phage F116L were not affected by the presence of the cloned c1 gene of D3. When the D3 DNA f...

The ultraviolet sensitivity gene of Escherichia coli B was introduced into a K-12 recipient by transduction with phage P1. The uvs gene of E. coli B is cotransducible with the proC locus of K-12, is closely linked to tsx, is not linked to lacZ, and only rarely to purE. The transductants are mucoid, filamentous on irradiation, and show plating-medium response. The order of markers is lacZ proC t...

introduction it has long been known that ionizing radiation can lead to detrimental effects in normal cells. in this light, radioprotective chemicals have been used to decrease morbidity or mortality caused by ionizing irradiation. this study aimed to evaluate the radio-protective effect of n-acetylcysteineagainst radiation-induced mortality in male mice. materials and methods 52 healthy male m...

In this work a novel colour-difference measurement method for the quality evaluation of copper deposited on a polymer is proposed. Laser-induced selective activation (LISA) was performed onto the surface of the polycarbonate/acrylonitrile butadiene styrene (PC/ABS) polymer by using nanosecond laser irradiation. The laser activated PC/ABS polymer was copper plated by using the electroless copper...

We determined the frequencies of dicentric chromosomes per cell in non-dividing confluent normal human fibroblasts (MRC-5) irradiated with a single 1 Gy dose or a fractionated 1 Gy dose (10X0.1 Gy, 5X0.2 Gy, and 2X0.5 Gy). The interval between fractions was between 1 min to 1440 min. After the completion of X-irradiation, the cells were incubated for 24 hours before re-plating at a low density....

Due to the high uniformity demands, nickel deposition processes for producing reflector coatings often make use of dedicated plating cell configurations. Computer simulations can drastically speed up the trial and error stage for optimizing the plating cell design. In this paper, the nickel deposition distribution for a reflector application is simulated using the Elsyca PlatingMaster software ...
