Gu Ralstonia UXSlike UDP-4ketoxylose synthase paper

We have identified an operon and characterized the functions of two genes from the severe food poisoning bacterium, Bacillus cereus subsp. cytotoxis NVH 391-98 that are involved in the synthesis of a unique UDPsugar, UDP-2-Acetamido-2-deoxy-xylose (UDPN-acetyl-xylosamine, UDP-XylNAc). UGlcNAcDH encodes a UDP-N-acetylglucosamine 6-dehydrogenase converting UDPN-acetyl-glucosamine (UDP-GlcNAc) to ...

David Oliver: Values statements aren't worth the paper.

In A Sceptic’s Medical Dictionary, the great Michael O’Donnell mademischievous fun of mission statements in the NHS, calling them “pious utterances trusts print below their expensively commissioned logo.”Values statements are close siblings; both are ubiquitous in health and social care. There’s nothing wrong with publicising your guiding values. But I suspect that most patients and families wo...

Angiogenesis is a compensatory mechanism that enables malignant tumors to survive in an oxygen-deficient environment. To test our hypothesis that hypoxia stimulates the production of angiopoietin-2 (Ang-2) in colorectal cancer (CRC), we investigated the expression of Ang-2 in three cultured CRC cell lines, and in specimens from 11 CRC metastatic liver tumors. Hypoxia-induced Ang-2 mRNA expressi...

Seek and Ye Shall Find

This chapter proposes that search engines apply a verticalizing pressure on the WWW many-to-many information distribution model, forcing this to revert to a distributive model similar to that of the mass media. The argument for this starts with a critical descriptive examination of the history of search mechanisms for the Internet. Parallel to this there is a discussion of the increasing ties b...
