A reversed-phased HPLC method that allows the separation and simultaneous determination of the preservatives benzoic (BA) and sorbic acids (SA), methyl- (MP) and propylparabens (PP) is described. The separations were effected by using an initial mobile phase of methanol-acetate buffer (pH 4.4) (35:65) to elute BA, SA and MP and changing the mobile phase composition to methanol-acetate buffer (p...

They reported that the date of the cloth's production lay between A.D. 1260 and 1390 with 95% confidence. This came as a surprise in view of the technology used to produce the cloth, its chemical composition, and the lack of vanillin in its lignin. The results prompted qu...

This paper presents unexpectedly early dates for a Tupiguarani settlement in Southeastern Brazil. One radiocarbon dating of 1740 +/- 90 yr BP (1820-1390 cal yr BP) was already available for the Morro Grande site (Araruama, southeastern coast of Rio de Janeiro State). Two new dates, obtained from charcoal samples, are reported here. An age of 2920 +/- 70 yr BP (3220-2790 cal yr BP) was obtained ...

Axelrod and Hamilton (Science 211:1390, 1981) suggested that trisomies may result from an end-game strategy between chromosomes competing to get on the gamete as the mother approaches menopause. We tested this hypothesis by reviewing studies of the parental origin of the extra chromosome in trisomy 21 births. These data show that there is no significant rise in trisomy 21 conceptions as the mot...
