The sensitivity of pollen as an indicator of elevation inneotropical lowlandandAndean forestswasmeasured usingmodern pollen samples collected frommoss-polsters along a transect between 340 mand 3530 m elevation and from surface sediments in lowland swamps (240 m) of Madre de Dios, Peru. A blind study, using samples collected from the same transect in the following year, provided a test of repro...

ETHNOPHARMACOLOGICAL RELEVANCE Extracts of plant species, used traditionally to treat malaria, have been extensively investigated for their activity against Plasmodium intraerythrocytic asexual parasites in search of new antimalarial drugs. However, less effort has been directed towards examining their efficacy in blocking transmission. Here, we report the results of the in vitro screening of e...

DNA fingerprint analysis of genetic relatedness between rose genotypes, using humanderived minisatellite probes, correctly reflected relationships within and between categories of rose plants. Nearly identical DNA fingerprint patterns were observed for cultivars 'Dick Koster' and its two sports. A high level of similarity was detected between genotypes of the hybrid tea category while a low lev...

BACKGROUND Glycosylation is one of the most common post-translational modifications of eukaryotic proteins and is known to undergo dynamic changes in a wide range of biological processes. To date, however, the glycan expression profiles in endometriosis are largely unknown. The objective of the study was to identify the panel of glycans that were aberrantly expressed in endometriosis, a hormone...

Four novel anthraquinone-benzisochromanquinone dimers, named floribundiquinones A, B, C, and D (1-4), along with six known anthraquinones, 10-(chrysophanol-7'-yl)-10-hydroxychrysophanol-9-anthrane (5), physcion (6), chrysophanol (7), 1,5,8-trihydroxy-3-methyl-anthraquinone (8), aloe-emodin (9), and xanthorin (10), were isolated from the roots of Berchemia floribunda. Their structures including ...
