CONFENIS Special Session on the International Symposium on Electronic Marketplace Integration & Interoperability (EM2I'07)
EM2I'07 is a new venue for presenting state-of-the-art research and development achievements in the design, introduction, and use of integration technology for electronic marketplaces that affect business interoperability between firms and within supply chains. Although traditional forms of e-marketplaces such as intermediaries, supplier portals, and content hubs are an important area of focus,...
متن کاملURINARY 6b-HYDROXYCORTISOL EXCRETION IN RHEUMATOID ARTHRITIS
The objective was to analyse whether the activity of the cytochrome P450 isoenzyme CYP3A4 is altered by disease activity of rheumatoid arthritis (RA). Urinary 6b-hydroxycortisol excretion, expressed as a fraction of the urinary creatinine output, was measured in 21 patients with RA treated with three different disease-modifying anti-rheumatic drugs (DMARDs) over 24 weeks. There were no correlat...

The title compound, C32H48O4, which was extracted from the bark of Rhododendron arboreum, consists of five fused rings to which an acetate and seven methyl groups are attached. The A, D and E rings adopt chair conformations, the B ring is in a distorted chair and the C ring is in a half-chair conformation. The five-membered ring formed by the lactone group, which bridges from the A/B to the B/C...
متن کامل5b,6b-Epoxy-17-oxoandrostan-3b-yl acetate and 5b,6b-epoxy-20-oxo- pregnan-3b-yl acetate
In the title compounds, C21H30O4, (I), and C23H34O4, (II), respectively, which are valuable intermediates in the synthesis of important steroid derivatives, rings A and B are cis(5 ,10 )-fused. The two molecules have similar conformations of rings A, B and C. The presence of the 5 ,6 -epoxide group induces a significant twist of the steroid nucleus and a strong flattening of the B ring. The dif...
