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

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
