[作者:Smith, SY; Collinson, ME; Rudall, PJ,期刊:American Journal of Botany, 页码:688-699 , 文章类型: Article,,卷期:2008年95-6]
- The first known fossil fruits and seeds of Cyclanthaceae are described here. Cyclanthus messelensis sp. nov., from the Middle Eocene of Messel, Germany, has discoidal fruiting cycles up to 6 cm in diameter, with a centra...
- Thiasugars: Potential Glycosidase Inhibitors
[作者:Yuasa, H; Izumi, M; Hashimoto, H,期刊:Current Topics in Medicinal Chemistry, 页码:76-86 , 文章类型: Review,,卷期:2009年9-1]
- The inhibitory activities against glycosidases of synthetic thiasugars, the ring sulfur analogs of carbohydrate, were surveyed with a special emphasis on our own studies. 5-Thio-L-fucose, the ring sulfur analog of L-fuco...
- Hybridization between invasive Spartina densiflora (Poaceae) and native S-foliosa in San Francisco Bay, California, USA

- Rapid evolution in contemporary time can result when related species, brought together through human-aided introduction, hybridize. The significant evolutionary consequences of post-introduction hybridization range from ...
- Origin and evolution of the northern hemisphere disjunction in the moss genus Homalothecium (Brachytheciaceae)
[作者:Huttunen, S; Hedenas, L; Ignatov, MS; Devos, N; Vanderpoorten, A,期刊:American Journal of Botany, 页码:720-730 , 文章类型: Article,,卷期:2008年95-6]
- Competing hypotheses that rely either on a stepping-stone dispersal via the North Atlantic or the Bering land bridges, or more recent transoceanic dispersal, have been proposed to explain the disjunct distribution of Med...
- Implications of the Dominant Role of Transporters in Drug Uptake by Cells
[作者:Dobson, PD; Lanthaler, K; Oliver, SG; Kell, DB,期刊:Current Topics in Medicinal Chemistry, 页码:163-181 , 文章类型: Review,,卷期:2009年9-2]
- Drug entry into cells was previously believed to be via diffusion through the lipid bilayer of the cell membrane, with the contribution to uptake by transporter proteins being of only marginal importance. Now, however, d...
