Studies on the Cell Toxin Produced by X-Ray Irradiation

Induction of radioresistant nasopharyngeal carcinoma cell line CNE-2R by repeated high-dose X-ray irradiation

Background: All To enhance the curative effect of radiotherapy, we established a radio-resistant cell line, CNE-2R from CNE-2, a radio-sensitive type of CNE, through repeated irradiation. The developed cell line provides a basis for further studies on the radio-resistance of CNE and the molecular mechanism of radiotherapy sensitization drugs. Materials and Methods: The CNE-2 cell line was selec...

Studies on combined x-ray irradiation and chemotherapy.

Studies on a toxin produced by the cyanobacterium Phormidium persicinum.

As part of an on-going project to detect extracellular algal compounds of potential medicinal value aqueous culture supernatants and methanolic cell extracts of randomly selected algae were screened for the presence of bioactive compounds using electrically stimulated guineapig ileum preparations[l] and a brine shrimp assay[2]. Bioactive compounds were detected in the methanolic extract of the ...

Strong x-ray emission from high-temperature plasmas produced by intense irradiation of clusters.

The interaction of an intense laser pulse with large s,100 Åd clusters present in pulsed gas jets is shown to produce novel plasmas with electron temperatures far in excess of that predicted by abovethreshold ionization theory. The enhanced absorption of the laser light by the dense clusters results in the production of high ion charge states via collisional ionization resulting in strong x-ray...
