Entrepreneurship research has been built upon a historical foundation grounded in economic change. To understand the development of the field, it is useful to understand the motivations and interests of key scholars and to trace the linkages between these scholars and other authors, from the transient to the contributor. This has been done through a bibliometric analysis of research articles cited
Background: More than one-half of all pregnant women suffer from nausea and vomiting during pregnancy (NVP), primarily during the first trimester. Methods: Prospectively ascertained information on drug use during pregnancy was obtained from the Swedish Medical Birth Register during the period July 1, 1995 to 2002. Antiemetics (antiemetic antihistamines, dopamine modulators, and ondansetron) primar
A class of high-order reconstruction methods based on logarithmic functions is presented. Inspired by Marquina's hyperbolic method, we introduce a double logarithmic ansatz of fifth order of accuracy. Low variation is guaranteed by the ansatz and (slope-) limiting is avoided. The method can reconstruct smooth extrema without order reduction. Fifth order of convergence is verified in a numerical ex
Läkarstuderande bör få upplevelsebaserad utbildning i samtalsmetodik, och deras handledare bör utbildas på samma sätt. Utbildningen bör, för att få långsiktig effekt, integreras med klinisk praktik och betona problemdefinierande färdigheter. Kurser i konsultationsmetodik anordnades för att dels utveckla läkarnas egna konsultationer, dels utveckla en feedbackmodell att använda i handledning av läka
Analys av tematiska och stilistiska paralleller mellan filmen Sommarnattens leende och teateruppsättningen En vintersaga - båda i regi av Ingmar Bergman.
In this paper, two approaches to data mining of time series have been tested and compared. Both methods are based on the wavelet decomposition of data series and allow the localization of important characteristics of a time series in both the time and frequency domain. The first method is a common method based on the analysis of wavelet power spectra. The second approach is new to the applied fiel
Popular Abstract in Swedish Hematopoes är den process under vilken alla röda och vita blodceller i kroppen bildas. Denna process sker kontinuerligt i benmärgen och förser kroppen med blodceller under hela livet. I benmärgen finns en viss typ av omogna celler sk stamceller som alla olika typer av blodceller bildas ifrån. Genom att stamceller gradvis mognar så bildas mogna blodceller som transporterThe Wilms tumor gene 1 (WT1) encodes a zinc-finger containing transcription factor which is highly expressed in immature hematopoietic progenitor cells. A high expression of WT1 and the presence of somatic mutations in acute leukemia indicate a role for WT1 in the pathogenesis of leukemia. The ojective of this thesis was to investigate the role of WT1 during human hematopoiesis and leukemia. To ga
Glucagon- like peptide-1 ( GLP-1) plays a significant role in glucose homeostasis through its incretin effect on insulin secretion. However, GLP-1 also exhibits extrapancreatic actions, and in particular its possible influences on insulin sensitivity are controversial. To study the dynamic action of GLP-1 on insulin sensitivity, we applied advanced statistical modeling methods to study glucose dis
Between 20 and 30 per cent of all breast cancers show an overexpression of the growth factor HER2 and this implies a worse prognosis. Metastasising breast cancer that overexpress HER2 can effectively be treated with trastuzumab (Herceptin). In order to determine whether this treatment is indicated, HER2 expression must be quantified with immunohistochemical or molecular biological methods. Several
The ability to perceive and express prosodic qualities of speech was tested in 21 patients with a single focal ischaemic disturbance of the right hemisphere, 14 patients having an infarct and 7 transient ischaemic attacks, and in 21 age-matched normal controls. All patients were predominantly right-handed. None showed signs of aphasia. Pure tone audiometry showed acceptable hearing for speech. The
Background. Goodpasture's disease (GP) is a rare but severe disease characterized by anti-glomerular basement membrane antibodies, rapidly progressive glomerulonephritis and lung haemorrhage. The autoantibodies are restricted to a narrow epitope region on the NC1 domain of the alpha3 chain of type IV collagen. GP is strongly associated with major histocompatibility complex (MHC) allele HLA DRB1-15
Milk fat globule membrane (MFGM) lipids have been studied in the presence and absence of proteins -lactoglobulin and -casein. The aim of this study was to relate the self-assembly structure, e.g. vesicles, formed in aqueous dispersions of MFGM lipids to the lipid composition, electrolyte composition as well as the effect of added milk proteins, i.e. -lactoglobulin and -casein. For this purpose, ve
Background and Purpose - Stroke induced by middle cerebral artery occlusion (MCAO) causes long-term formation of new striatal neurons from stem/progenitor cells in the subventricular zone (SVZ). We explored whether MCAO leads to hypoxia, changes in vessel density, and angiogenesis in the ipsilateral SVZ and adjacent striatum, and determined the relation between the migrating neuroblasts and the va
