The structures of cofactor-free haloperoxidases from Streptomyces aureofaciens, Streptomyces lividans, and Pseudomonas fluorescens have been determined at resolutions between 1.9 A and 1.5 A. The structures of two enzymes complexed with benzoate or propionate identify the binding site for the organic acids which are required for the haloperoxidase activity.(More)
2,3-Dihydroxybiphenyl 1,2-dioxygenase, an enzyme of the biphenyl biodegradation pathway that cleaves the first of the aromatic rings, was purified to apparent homogeneity from Pseudomonas sp. strain LB400 that had been engineered to hyperexpress the bphC gene. The enzyme had a subunit molecular mass of 33.2 kDa as determined by SDS-polyacrylamide(More)
Fibroblast growth factors (FGFs) constitute a family of at least 20 structurally related heparin-binding polypeptides active in regulating cell growth, survival, differentiation and migration. FGF9, originally discovered as a glia-activating factor, shares 30% sequence identity with other FGFs and has a unique spectrum of target-cell specificity. FGF9(More)
Demographical changes in high income counties will increase the need of health care services but reduce the number of people to provide them. Welfare technology is launched as an important measure to meet this challenge. As with all types of technologies we must explore its ethical challenges. A literature review reveals that welfare technology is a generic(More)
The emerging concept of systems medicine (or 'P4 medicine'-predictive, preventive, personalized and participatory) is at the vanguard of the post-genomic movement towards 'precision medicine'. It is the medical application of systems biology, the biological study of wholes. Of particular interest, P4 systems medicine is currently promised as a revolutionary(More)
The Scandinavian welfare states have public health care systems which have universal coverage and traditionally low influence of private insurance and private provision. Due to raises in costs, elaborate public control of health care, and a significant technological development in health care, priority setting came on the public agenda comparatively early(More)
Tryparedoxins (TXNs) catalyse the reduction of peroxiredoxin-type peroxidases by the bis-glutathionyl derivative of spermidine, trypanothione, and are relevant to hydroperoxide detoxification and virulence of trypanosomes. The 3D-structures of the following tryparedoxins are presented: authentic tryparedoxin1 of Crithidia fasciculata, CfTXN1; the his-tagged(More)
A procedure for the purification of a very hydrophobic lipase from Pseudomonas sp. strain ATCC 21808 was elaborated by avoiding the use of long-chain detergents in view of subsequent crystallization of the enzyme. The purification procedure included chromatography on Q-Sepharose in the presence of n-octyl-beta-D-glucopyranoside, Ca2+ precipitation of fatty(More)
Biobank research is potentially fruitful. It is argued that broad consent is acceptable for future research on biological material because a) the benefit is high, b) it pays respect to people's autonomy, c) it is consistent with current practices and d) because the risk is low. Furthermore, broad consent should be allowed if information is handled safely,(More)

OBJECTIVES Although ethics has been on the agenda in health technology assessment (HTA) since its inception, the integration of moral issues is still not standard and is performed in a vast variety of ways. Therefore, there is a need for a procedure for integrating moral issues in HTA. METHODS Literature review of existing approaches together with(More)
