Human beta-globin was synthesized in Escherichia coli as a cleavable fusion protein, using the expression vector pLcIIFX beta-globin [Nagai, K. & Thøgersen, H. C. (1984) Nature (London) 309, 810-812]. The fusion protein cIIFX beta-globin was purified to homogeneity and cleaved at the junction by blood coagulation factor Xa; the authentic beta-globin was liberated. Beta-globin was folded in vitr...

Widely distributed species are normally subjected to spatial heterogeneity in environmental conditions. In sessile organisms like plants, adaptive evolution and phenotypic plasticity of key functional traits are the main mechanisms through which species can respond to environmental heterogeneity and climate change. While extended research has been carried out in temperate species in this regard...

We review the status of rare kaon decays, concentrating on modes with sensitivity to short-distance flavour physics. Invited Talk presented at the 3rd Workshop on Physics and Detectors for Daphne (DAΦNE 99), Frascati, 16-19 Nov. 1999

A phytochemical study of an ethanol-soluble extract from the root barks of Daphne tangutica Maxim., a traditional Tibetan herb medicine, led to the isolation of 30 compounds, including eight daphnane diterpenes, nine coumarines, six lignans, five phenylpropanoid derivatives, beta-sitosterol and p-hydroxy benzonate. Two compounds out of these isolates are new daphne diterpene analogs, and their ...

Phytotoxicity of Daphne gnidium L. was evaluated through the effect of incorporating leaves, stems and roots biomass into soil (at 12.5, 25, 50g/Kg) and irrigation by their aqueous extracts (50g/L), on the growth of two crops (Lactuca sativa L. and Raphanus sativus L.) and two weeds (Peaganum harmala L. and Scolymus maculatus L.). Results revealed a perceptible phytotoxic effect which increased...
