Cell studies of the DNA bis-intercalator Delta-Delta [micro-C4(cpdppz)2-(phen)4Ru2]4+: toxic effects and properties as a light emitting DNA probe in V79 Chinese hamster cells

DNA probe in V79 Chinese hamster cells

Coordination complexes of type [Ru(L)3] , where L is a nitrogen-containing aromatic bidentate ligand, can often be photolytically reduced, making them useful in studies of DNAor protein-mediated electron transfer and in artifical photosynthesis model systems. Upon binding to DNA some Ru(L) complexes have been found to display strongly increased fluorescence compared with when free in solution, ...

The p53 status of Chinese hamster V79 cells frequently used for studies on DNA damage and DNA repair.

Chinese hamster lung fibroblast V79 cells have been widely used in studies of DNA damage and DNA repair. Since the p53 gene is involved in normal responses to DNA damage, we have analyzed the molecular genetics and functional status of p53 in V79 cells and primary Chinese hamster embryonic fibroblast (CHEF) cells. The coding product of the p53 gene in CHEF cells was 76 and 75% homologous to hum...

protective effect of boric acid on oxidative dna damage in chinese hamster lung fibroblast v79 cell lines

background: many studies have been published on the antioxidative effects of boric acid (ba) and sodium borates in in vitro studies. however, the boron (b) concentrations tested in these in vitro studies have not been selected by taking into account the realistic blood b concentrations in humans due to the lack of comprehensive epidemiological studies. the recently published epidemiological stu...

critical period effects in foreign language learning:the influence of maturational state on the acquisition of reading,writing, and grammar in english as a foreign language

since the 1960s the age effects on learning both first and second language have been explored by many linguists and applied linguists (e.g lennerberg, 1967; schachter, 1996; long, 1990) and the existence of critical period for language acquisition was found to be a common ground of all these studies. in spite of some common findings, some issues about the impacts of age on acquiring a second or...
