The title compound, C(32)H(50)O(10), prepared from a mixture of α- and β-dihydro-artemisinin, has two β-arteether moieties linked via an -OCH(2)CH(2)O- bridge, so that the mol-ecule is symmetric about the bridge. Each asymmetric unit contains a β-arteether moiety and an -OCH(2) group, which is only one-half of the mol-ecule. The endo-peroxide bridges of the parent compounds have been retained i...

2015 Ungefär 100 kilo ATP syntetiseras i kroppen varje dag av ATP-syntas, ett sammansatt proteinkomplex med tre aktiva centra. Komplexet sitter förankrat i ett biologiskt membran med hjälp av hydrofob attraktion och består av en roterande och en statisk del. En ATP-molekyl syntetiseras per tredjedels varv. Trots att varje aktivt centrum skulle kunna fungera oberoende av de andra, sparas mycket ...

In the world of CAD and GIS there is a growing need for storing spatial information in neutral contexts. Storing the information in a database rather than in files gives rise to greater options concerning what can be done with the information. Being able to perform analyses on spatial information is an area of interest for many companies. In particular since analyses provide foundations for pla...

Patients with bicuspid aortic valve (BAV) have an increased risk of developing ascending aortic aneurysm compared with individuals with a tricuspid aortic valve (TAV). A crucial factor involved in vascular remodeling during aneurysm development is transforming growth factor-β (TGF-β) and impaired signaling of this pathway can alter important extracellular matrix (ECM) protein such us fibronecti...

It is a well-known fact that the books of Hebrew Bible are, to great extent, anonymous and individuals long identified as their authors (Moses, Isaiah, David, Solomon, so on) are not ones who have penned them. How, then, should few paratexts do, in fact, relate texts explicitly named be understood? In this article, I argue such question essentially related historical contingency author concepts...
