Chromosome 17 and 21 aneuploidy in buccal cells is increased with ageing and in Alzheimer's disease.

Philip Thomas et al.

Mutagenesis, 23(1), 57-65 (2007-12-01)

Alzheimer's disease (AD) is a premature ageing syndrome characterized by cognitive impairment arising from neuropathological changes occurring within specific areas of the brain. We report a 1.5-fold increase in trisomy 21 (P < 0.001) and a 1.2-fold increase in trisomy

Rates of formation and thermal stabilities of RNA:DNA and DNA:DNA duplexes at high concentrations of formamide.

J Casey et al.

Nucleic acids research, 4(5), 1539-1552 (1977-01-01)

The thermal stabilities of RNA:DNA hybrids are substantially greater than those of DNA:DNA duplexes in aqueous electrolyte solutions containing high concentrations of formamide. Association rates to form DNA:DNA duplexes and DNA:RNA hybrids have been measured in these solvents. There is
