Superparamagnetic iron oxide nanoparticles (SPIONs) as a multimodality imaging probe for sentinel nodes : Design and Preclinical Evaluation

Bröst- och hudcancerceller sprider sig via lymfatiska systemet och fastnar i en eller två regionala sentinel lymfnoder (SLN) där de med stor sannolikhet växer till metastaser. Därför är SLN-biopsier och relaterade histopatologiska undersökningar viktiga vid cancerdiagnostiken för att bestämma sjukdomsstatus och att från denna kunna bestämma rätt behandling. Patienter vars lymfnoder innehåller spriBreast cancer and malignant melanoma disseminate through the lymphatic system and the first metastases arise in one or two regional, sentinel lymph nodes (SLNs) draining the primary tumour site. Therefore, identification and characterization of the SLNs is of major importance for cancer staging and for choice of therapy in patients. The standard clinical procedure relies on lymphoscintigraphy afte

Unrelated diversification in latecomer contexts—The emergence of the Chinese solar photovoltaics industry

New industries emerge in increasingly complex spatial patterns that challenge existing explanations of industrial path creation. In particular, the case of latecomer regions building up industries in fields that are unrelated to their previous industrial capabilities is not well understood in the literature. This paper aims to address this gap by expanding on an analytical framework that draws on

The art of strategic improvisation: A professional concept for contemporary communication managers

The purpose of this paper is to describe strategic improvisation, a contemporary concept and approach based on the creative arts and organizational crisis theory, as a valuable approach for communication professionals. Strategic improvisation combines the need for planning and structure with creative action, and is a normative idea of how to work in an efficient way.Design/methodology/approach: Th

Large uncertainty in carbon uptake potential of land-based climate-change mitigation efforts

Most climate mitigation scenarios involve negative emissions, especially those that aim to limit global temperature increase to 2°C or less. However, the carbon uptake potential in land-based climate change mitigation efforts is highly uncertain. Here, we address this uncertainty by using two land-based mitigation scenarios from two land-use models (IMAGE and MAgPIE) as input to four dynamic globa

Matrix-assisted laser desorption/ionization time-of-flight mass spectrometry analysis of 36 blood group alleles among 396 Thai samples reveals region-specific variants

BACKGROUND: Blood group phenotype variation has been attributed to potential resistance to pathogen invasion. Variation was mapped in blood donors from Lampang (northern region) and Saraburi (central region), Thailand, where malaria is endemic. The previously unknown blood group allele profiles were characterized and the data were correlated with phenotypes. The high incidence of the Vel-negative

Förstärkning av murade väggar genom ytarmering av stålnät : Resultat från experimentella studier och beräkningar

Rapporten sammanfattar resultaten från en experimentell undersökning där murade väggar belastade med samtidigt verkande normallast och moment har förstärkts genom ytarmering. En metod för beräkning av väggars bärförmåga i den aktuella lastsituationen presenteras. Förstärkningstekniken kan användas såväl i samband med renovering och energieffektivisering av fullmurade ytterväggar med omfattande fro

Essays on Matching

This thesis makes a contribution to matching theory and mechanism design. It consists of four self-contained papers focusing on kidney exchange, object allocation and partnership formation. The first paper, Pairwise Kidney Exchange over the Blood Group Barrier, investigates how the use of immunosuppressive drugs can be implemented within kidney exchange programs. Thanks to advances in medicine, im

Public talk on personal troubles : A study on interaction in radio counselling

Denna doktorsavhandling undersöker samtal om personliga problem i mötet med en specialist i radio. I synnerhet handlar studien om den dynamiska process då förståelse skapas – när upplevelser av personliga bekymmer förklaras och definieras som problem av särskilda slag. Denna meningsskapande process undersöks i detalj så som den utspelar sig i dialoger i radio och mellan programdeltagare och radiolThe dissertation examines how personal troubles are talked about in an encounter with a professional on the public arena of radio broadcasting, where the professional has to meet the challenge of making professional advice not only useful for the person seeking help, but also relevant or interesting for the radio audience. The study explores the dynamic process of shaping an understanding of probl

Epidemiology of kidney failure and glomerulonephritis in Sweden. Hereditary and non-hereditary factors.

Background: Kidney disease is recognised as an important worldwide health burden. Kidney failure is the result of acute and chronic kidney disease and is associated with morbidity and mortality. Chronic kidney failure is associated with high-costs for society and low quality of life. Kidney failure may progress to end-stage renal disease (ESRD) that requires dialysis or kidney transplantation with

Toward Inclusive Pharmaceutical Packaging : An Innovation and Design Process Perspective

Pharmaceutical packaging has an increasing importance in aging societies, wherepeople depend on medicines for their own care and well-being. Previous research shows that pharmaceutical packaging is a source of uncertainties, confusion, and daily struggles. The challenges experienced by users are extensive; the pharmaceutical industry needs to respond with packaging innovation. To address these com

Religion och coping - om religionens roll i hanterandet av kriser

I den psykologiska forskningen om coping har religionens betydelse för människans hanterande av stressfyllda situationer alltmer uppmärksammats under de senaste decennierna. I den religionspsykologiska copingforskningen ses religionen som mångdimensionell; religionen ses som känsla, tanke, handling och som ett socialt fenomen. I sökandet efter signifikans kan religionen en process som relaterar ti

Light-dependent magnetoreception in zebra finches : - from behaviour to receptor

Fåglarnas förmåga att flyga över extremt långa sträckor utan att hamna vilse harförvånat människor i århundraden. Det är känt att djur kan använda solens ellerstjärnornas läge, landmärken och jordens magnetfält som informationskälla förorientering, det vill säga de kan använda källan för att få kompassinformation.Eftersom magnetfältet är närvarande överallt på planeten kan magnetiskkompassinformatIt is well known that animals can use a wide variety of information sources to help them orient and navigate asthey move over short or long distances. Birds can rely on information from the sun, the skylight polarizationpattern, the stars, landmarks and the Earth’s magnetic field for orientation and navigation. However, despite thebehavioural evidence supporting the use of the magnetic field as an

Multiconfiguration dirac-hartree-fock calculations with spectroscopic accuracy : Applications to astrophysics

Atomic data, such as wavelengths, spectroscopic labels, broadening parameters and transition rates, are necessary for many applications, especially in plasma diagnostics, and for interpreting the spectra of distant astrophysical objects. The experiment with its limited resources is unlikely to ever be able to provide a complete dataset on any atomic system. Instead, the bulk of the data must be ca
