Prevalence of extended-spectrum beta-lactamase-producing bacteria in food.

Extended-spectrum β-lactamase (ESBL)-producing Enterobacteriaceae with Cefotaximase-München (CTX-M) enzymes are rapidly increasing worldwide and pose a threat to health care. ESBLs with CTX-M enzymes have been isolated from animals and different food products, but it is unknown if food imported from the Mediterranean area may be a possible reservoir of these bacteria. During 2007-2008, swab sample

Long term effects on human plasma lipoproteins of a formulation enriched in butter milk polar lipid.

BACKGROUND: Sphingolipids (SL), in particular sphingomyelin (SM) are important components of milk fat polar lipids. Dietary SM inhibits cholesterol absorption in rats (Nyberg et al. J Nutr Biochem. 2000) and SLs decrease both cholesterol and TG concentrations in lipid- and cholesterol fed APOE*3Leiden mice (Duivenvoorden et al. Am J Clin Nutr. 2006). This human study examines effects of a butter m

Funktionshinder, säkerhet, osäkerhet och katastrofer

Denna rapport är resultatet av ett uppdrag från Räddningsverket till Certec att göra en dokumentation som tar upp specifika perspektiv på säkerhet, osäkerhet och katastrofer för människor med funktionshinder, äldre och barn. Den har en initierande och öve

Kit regulates maintenance of quiescent hematopoietic stem cells.

Hematopoietic stem cell (HSC) numbers are tightly regulated and maintained in postnatal hematopoiesis. Extensive studies have supported a role of the cytokine tyrosine kinase receptor Kit in sustaining cycling HSCs when competing with wild-type HSCs posttransplantation, but not in maintenance of quiescent HSCs in steady state adult bone marrow. In this study, we investigated HSC regulation in Whit

Modeling of Spark to Ignition Transition in Gas Mixtures

Popular Abstract in Swedish Den här avhandlingen behandlar modeller för studier av gnist-urladdningar i kemiskt icke-reagerande gaser. Modellerna är härledda från grundläggande principer inom ramen för kontinuums mekanik. De processer som sker under övergången från en gnista till en flamma kan delas upp i fysikaliska och kemiska processer. Denna studie är inriktad på de fysikaliska processerna. PlThis thesis pertains to the models for studying sparking in chemically inert gases. The models are derived from the basic principles and framework in continuum mechanics. The processes taking place in a spark to flame transition can be segregated into physical and chemical processes. This study is focused on physical processes. The plasma is regarded as a single-substance material. One and two-dim

Lightwave Analogue Links For LHC Detector Front-ends

The requirements on optical links for transferring analog and digital signals from the detector front-ends to the readout electronics at future high-luminosity colliders are reviewed. The advantages of external modulation techniques are discussed. An outline is given of the the R&D programme recently started at CERN by a collaboration involving high-energy physics institutes, optoelectronics r

Undisplaced femoral neck fractures-no problems? A consecutive study of 224 patients treated with internal fixation.

224 patients with undisplaced femoral neck fractures treated with two parallel Hansson hook pins were studied. After a mean follow-up time of 32 months (S.D. 5.2), 15% had a reoperation. 11% were considered failures, mostly avascular necrosis, and 9% had a secondary arthroplasty. Possible risk factors for poor outcome were analysed. Neither high age nor surgical delay was associated with increased

A tour to sustainability?: A discussion on the potential for tour operators to promote sustainable tourism

Aiming to start a constructive debate,“A tour to sustainability?” examines the preparedness of the tour operating sector to undertake the challenges of sustainable tourism. Drivers and barriers for acknowledging operators’ share of impacts and consequently their responsibilities for actions are presented and analysed further. The influential potential of tour operators in tourism industry is defin
