Intra cerebral tumours were inoculated into the brain of Fischer-344 syngeneic rats. After one week they were treated with either 5 or 15 Gy of Co-60-gamma radiation. The first immunization was given 1 hour before the radiation treatment and then two more times with 14-day intervals. Immunization was performed with 3 x 10(6) radiation sterilized IFN-gamma secreting tumour cells (N29) injected intr
By pulse-modulating a cw dye-laser beam and employing the delayed-coincidence technique, we have determined the natural radiative lifetimes of a number of atomic states in rare-earth atoms Eu, Dy, and Yb. In the measurements, which were performed on an atomic beam, exponential decay curves with good statistics were obtained using short measuring times. The general features of the technique are dis
Pathogenic microbes have evolved sophisticated molecular strategies to subvert host defenses. Here we show that virulent bacteria interfere directly with Toll-like receptor (TLR) function by secreting inhibitory homologs of the Toll/interleukin-1 receptor (TIR) domain. Genes encoding TIR domain containing–proteins (Tcps) were identified in Escherichia coli CFT073 (TcpC) and Brucella melitensis (Tc
Popular Abstract in Swedish Hur börjar en infektion och vad avgör vem som drabbas? Hur ser den sjukdomsframkallande bakterien ut, och hur försvarar vi oss mot dess angrepp? Vi studerar dessa frågor med urinvägsinfektioner som modell. De flesta urinvägsinfektioner orsakas av E. coli bakterier med speciella ytstrukturer som de använder för att angripa slemhinnan i urinvägarna. Genom sin starka förmUrinary tract infections (UTI) are among the most common infections in man. Despite their prevalence, information on the molecular mechanisms defects that explain the increased susceptibility to disease are lacking. This study focused on mucosal inflammation and the molecular mechanisms by which uropathogenic Escherichia coli activate this response. P fimbriae are expressed by most E. coli strain
Aims: Chronic left atrial enlargement (LAE) increases the risk of atrial fibrillation. Electrocardiogram (ECG) criteria might provide a means to diagnose LAE and identify patients at risk; however, current criteria perform poorly. We seek to characterize the potentially differential effects of atrial dilation vs. hypertrophy on the ECG P-wave. Methods and results: We predict effects on the P-wave
Rap lyrics in Sweden have become increasingly multilingual in the past twenty years. In this chapter, Karin Nykvist provides insights into contemporary Swedish hip-hop and its use of multilingualism. In her analysis of Swedish rap poetics, Nykvist shows how hip-hop lyrics turn to multilingual aesthetics in order to destabilize and question ideas of national identity and to deconstruct the monoling
Objective: Slipped capital femoral epiphysis (SCFE) in adolescence is associated with increased risk of future osteoarthritis (OA). The purpose of this study was to study clinical and radiographic risk factors for early cartilage degeneration after SCFE. Design: 22 patients (44 hips) (mean age 24 years, range 18-27) treated with in situ fixation (The Hansson hook-pin) for stable SCFE on average 11
The linearly polarized photon beam for photonuclear researches has been produced at MAX-lab facility on the base of coherent bremsstrahlung process of electrons in a diamond crystal. Test experiments have been performed at electron energies 143.9 and 192.7 MeV with a diamond crystal 0.1 mm thick. The measured coherent bremsstrahlung spectra demonstrate typical features to be observed at higher ele
Community currencies have emerged as a tool for building more inclusive local economic development and governance. Grassroots organisations in Nairobi and Mombasa (Kenya) have been experimenting with this form of local monies. Communities in informal settlements in Kisumu have shown interest in introducing their own community currency. Challenges remain concerning the best diffusion strategy of su
More than 20 years ago, an oxytocin/vasopressin-like peptide, CLITNCPRGamide, was isolated from the locust, Locusta migratoria [Proux JP, et al. (1987) Identification of an arginine vasopressin-like diuretic hormone from Locusta migratoria. Biochem Biophys Res Commun 149:180-186]. However, no similar peptide could be identified in other insects, nor could its prohormone be cloned, or its physiolog
For business and environmental reasons, increased understanding of green consumer behavior is essential. This paper addresses consumer adoption and non-adoption of a high involvement eco-innovation (the alternative fuel vehicle, AFV). The purpose is to integrate two research streams to explore factors driving and hindering adoption. The factors are rooted in environmental psychology research and t
Around the globe more than 350,000 citizens live with a sophisticated hearing aid device called Cochlear Implant. In many countries CI is an institutionalized medical procedure for restoring deafened with a technological sense of hearing but the social challenges for users is a largely unexplored issue. Addressing this social dimension, the article explores how Cochlear Implant works as a boundary
I den här artikeln diskuteras kustpolicyförändringar i Sverige och deras dynamik, med stranderosion ochstrandfodring som exempel. Analysen baseras på Multiple Stream – modellen, som är en teoretisk modell förpolicyutveckling och agendasättning, utvecklad av samhällsvetaren John Kingdon (1984, 2003). Kustskydd ärinte ett separat policyområde i Sverige; åtgärder för att skydda allmän kust är ofta en
Peder Winstrup – Historier kring en 1600-talsmumie är en populärvetenskaplig bok om en biskop i Lund med många strängar på sin lyra; professor i fysik, kunglig hovpredikant, fornforskare, arkitekt, författare, teolog, boktryckare, initiativtagare till Lunds universitet och turistguide – en sann renässansmänniska! Här beskrivs uppväxt och utbildning, hans residens och rättstvister. Läsaren får ta d
Within the project LATERES COCTILES early fired bricks have been the objectof a multifaceted investigation. One aim has been to elucidate the mechanisms behind the diffusion of this innovation. An inventory of Hellenistic and early Roman fired bricks around the Mediterranean resulted in an archaeological database comprising 276 brick contexts. Network analysis was applied to these data using a two
