Background: Heterogeneous findings have been reported in studies of basal ganglia volumes in schizophrenia patients as compared to healthy controls. The basal ganglia contain dopamine receptors that are known to be involved in schizophrenia pathology and to be vulnerable to pre- and perinatal hypoxic insults. Altered volumes of other brain structures (e.g. hippocampus and lateral ventricles) have
Collagen fibers expose distinct domains allowing for specific interactions with other extracellular matrix proteins and cells. To investigate putative collagen domains that govern integrin alpha(V)beta(3)-mediated cellular interactions with native collagen fibers we took advantage of the streptococcal protein CNE that bound native fibrillar collagens. CNE specifically inhibited alpha(V)beta(3)-dep
Identification of the molecule(s) that globally induce a robust regenerative state in sensory neurons following peripheral nerve injury remains elusive. A potential candidate is brain-derived neurotrophic factor (BDNF), the sole neurotrophin upregulated in sensory neurons after peripheral nerve injury. Here we tested the hypothesis that BDNF plays a critical role in the regenerative response of ma
Sample treatment is an essential element when using real-time PCR for quantification of pathogens directly on food samples. This study comparatively evaluated three different principles of sample treatment, i.e. immunomagnetic separation based on phage-derived cell wall binding molecules, matrix solubilization and flotation, in order to establish their suitability for quantifying low numbers of St
John Kingdon's Multiple Streams Framework (MSF) constitutes a powerful tool for understanding the policy process, and more specifically, agenda-setting, through three separate streams: problems, policies and politics. This article argues that the MSF would benefit from further development of the problem stream. It introduces a clearer conception of agency into the problem stream by suggesting the
Putative cellobiose dehydrogenase (CDH) genes are frequently discovered in various fungi by genome sequencing projects. The expression of CDH, an extracellular flavocytochrome, is well studied in white rot basidiomycetes and is attributed to extracellular lignocellulose degradation. CDH has also been reported for plant-pathogenic or saprotrophic ascomycetes, but the molecular and catalytic propert
Aerosol particle samples were collected, and the particle size distribution was measured during 1 year at the Zeppelin station (474 m asl) on Svalbard. The chemical constituents, hygroscopicity, and cloud forming properties of the aerosol were analyzed. The aerosol contained mostly sulfate and nitrate during the summer, whereas from September to February the main components were sodium and chlorid
Popular Abstract in Swedish Vad betyder ordet "hund"? Eller orden "ljudpinne", "måste", "gurka" och "röd"? Till skillnad från många tidigare forskare ser jag orden och våra språkliga uttryck som reaktioner på när saker och ting har blivit fel i våra vardagliga handlingar: anledningen till att jag måste ha ett ord för "röd" är att du kanske tog den blå skjortan i stället för den röda, och deWhat is the relation between the words in language and our everyday actions? Are linguistic structures dependent on our actions, or does language function on its own? This thesis deals with the pragmatic foundations of language and proposes a model of meaning in language that is based on our expectations about the world and about other people. On this view, language is seen as composed of three f
Popular Abstract in Swedish Den viktigaste uppgiften inom den kliniska cytologin är att påvisa cancerceller i olika typer av cellprover. Många olika cancertumörer sprider sig till lungsäcken och bukhålan och ger då ofta upphov till vätska (exsudat) som innehåller cancerceller. Ofta kan cancerdiagnosen ställas på grundval av cellernas utseende men detta är inte alltid möjligt, eftersom cancercellerClinical cytology is a rapid method to detect malignancy in effusions of the serous cavities, but the morphological characteristics of the cells do not always allow diagnosis and a specific marker for malignant cells would improve the diagnostic performance. Telomerase adds telomere repeats to the chromosome ends. It is the most promising universal indicator of malignancy and the project focuses o
The production of a W boson in association with a single charm quark is studied using 4.6 fb(-1) of pp collision data at root s = 7 TeV collected with the ATLAS detector at the Large Hadron Collider. In events in which a W boson decays to an electron or muon, the charm quark is tagged either by its semileptonic decay to a muon or by the presence of a charmed meson. The integrated and differential
This paper studies contextual effects on fertility at the onset of fertility decline in Sweden. We argue that the community exerts an influence on fertility when individuals belonging to a certain community are more similar to one another (within-area) in their reproductive behaviour than individuals living in another community (between-area). Our hypotheses are that community had a strong influen
This article focuses on patients’ participation in decision-making in meetings with healthcare professionals in a healthcare system, based on neoliberal regulations and ideas.Drawing on two constructed empirical cases, primarily from the perspective of patients, this article analyses and discusses the clinical practice around decision-making meetings within a Foucauldian perspective. Patients’ par
Background To assess the feasibility and psychosocial impact of a hospital-based home care (HBHC) program for children with cancer. Procedure A HBHC program was carried out with 51 children (018 years) with cancer to assess its feasibility in terms of satisfaction, care preferences, safety, and cost. A controlled trial was conducted to assess children's health-related quality of life (HRQOL) using
While negative effects of human disturbance on animals living above the ground have been widely reported, few studies have considered effects on animals occupying cavities or burrows underground. It is generally assumed that, in the absence of direct visual contact, such species are less vulnerable to disturbance. Seabird colonies can support large populations of burrow- and cavity-nesting species
In light of the many corporate scandals, social and ethical commitment of society has increased considerably, which puts pressure on companies to communicate information related to corporate social responsibility (CSR). The reasons underlying the decision by management teams to engage in ethical communication are scarcely focussed on. Thus, grounded on legitimacy and stakeholder theory, this study
Variation of PCO2 with concomitant changes in extracellular pH (pHo) may modulate cerebrovascular resistance, but the direct actions of carbon dioxide and pHo on human cerebral arteries are unknown. In this study, we have evaluated the effects of different carbon dioxide tensions (2.7, 4.2 and 7.2 kPa) with either fixed (pHo = 7.44) or concomitant changes in pHo, on contractions induced by depolar
Popular Abstract in Swedish Blodkärlen har till uppgift att distribuera syre och näring till kroppens alla celler, samt att borttransportera slaggprodukter som sedan bildas efter nyttjandet. Dessutom förmedlas en rad signalsubstanser till kroppens vävnader via blodcirkulationen. Eftersom mängden cirkulerande blod är begränsad är det viktigt att blodkärlen, bestående av artärer som för blodet från This thesis aims at characterizing the endothelin (ET) receptors in different vascular beds of man and rat. The ET-A receptor was shown to be the only contractile ET receptor present in all vascular regions, with the exception of the rat mesenteric vein where a weak ET-B receptor-mediated contraction was seen. Treatment with antisense oligodeoxynucleotides to the ET-A receptor mRNA during organ cu
Reduced urinary bladder capacity is a clinically significant problem. The surgical methods that have been available to treat this, such as urinary diversion or surgically augmenting the bladder by incorporation of intestinal segments, all have serious drawbacks. There is a need to understand how the smooth muscle of the intestine and bladder can interact when brought into close contact surgically,
PURPOSE: The aim of this study was to explore healthcare consumption in relation to more versus less knowledge concerning prescribed drugs among older people with functional dependency and repeated healthcare contacts, and to explore the determinants of more versus less knowledge METHODS: The sample comprised 63 persons (mean age 82.8 years). Data concerning use and knowledge about drugs, demograp
