Investments in cyberinfrastructure and e-Science initiatives are motivated by the desire to accelerate scientific discovery. Always viewed as a foundation of science, data sharing is appropriately seen as critical to the success of such initiatives, but new technologies supporting increasingly data-intensive and collaborative science raise significant(More)
The psoriasis-associated antigen, pso p27, can be isolated from psoriasis scale and is present in complement-activating immune complexes in psoriatic scale, and in serum from patients with psoriasis. The antigen is produced by tryptase-positive cells in the skin lesions and is shown to be a major antigen in the immune reactions in psoriasis. The synthesis(More)
BACKGROUND Pseudomonas aeruginosa is an opportunistic bacterium that can cause severe infection in susceptible patients. During the winter of 2001-2002, we investigated an outbreak of P. aeruginosa infection among patients in several hospitals across Norway. METHODS A nationwide outbreak investigation was performed with case finding, questionnaires, and(More)
Although much digital divide research focuses on access to technology, another cause of the divide is the lack of information awareness that we call information asymmetry. Information asymmetry often stems from inadequate information sharing and can result in negative consequences for both the information poor and the information rich. Information asymmetry(More)
Until recently, infections with methicillin-resistant Staphylococcus aureus (MRSA) have mainly been associated with hospital outbreaks in Norway. However, increasingly cases are contracted outside hospitals. This paper reports the first two outbreaks of MRSA in two nursing homes in central Norway, affecting 23 residents and five staff members. Pulsed-field(More)
Sarcoidosis is a multisystem granulomatous disorder of unknown etiology, predominantly affecting the lung. The increased concentration of pulmonary lymphocytes with specific receptors in subgroups of sarcoidosis patients suggests a local specific immune response. pso p27, a psoriatic scale antigen linked to the pathogenesis of psoriasis, was previously(More)
Two follow-up studies of a positive methicillin-resistant Staphylococcus aureus (MRSA) finding in the 2008 European Union baseline survey on MRSA in pig herds were performed to gain more knowledge about the epidemiology of the particular MRSA type, a known human type (ST8/t008), among pigs. Two persons on a Norwegian farm in the study were found to be MRSA(More)
In 2002 we investigated an outbreak comprising 231 patients in Norway, caused by Pseudomonas aeruginosa and linked to the use of contaminated mouth swabs called Dent-O-Sept. Here we describe the extent of contamination of the swabs, and identify critical points in the production process that made the contamination possible, in order to prevent future(More)
