This article examines the nature and geography of knowledge linkages in the Vienna software cluster. Empirical studies on the software sector have provided contradictory evidence of the relative importance of different sources of knowledge, the spatial dimension of exchanges of knowledge, and the relevance of different channels for the transmission of knowledge. Recent conceptual work on the geogr
Intraductal papillary mucinous neoplasms (IPMNs), characterized by intraductal papillary growth and thick mucin secretion, have increasingly been recognized. Despite modern preoperative evaluation, major difficulties still remain in distinguishing malignant invasive types from benign IPMNs. Following a PubMed database search, all relevant abstracts and articles on IPMN published in English and Chi
The purpose of this study was to evaluate an abdominal CT protocol in which radiation dose was reduced and IV contrast dose increased for young patients and radiation dose was increased and IV medium dose decreased for elderly patients. The hypothesis was that these adjustments would result in constant image quality and a reduction in age-specific risk.
SUMMARY: RankViaContact is a web service for calculation of residue-residue contact energies in proteins based on a coarse-grained model, and for visualization of interactions. The service provides information about ranked contact energies of residues, coordination numbers and the relative solvent accessibility of selected residues, as well as sequence and structure information. The program can be
To overview banks, repositories and registries of stem cell lines in Europe excluding bone marrow and cord blood banks; to concisely discuss the most important scientific, regulatory and ethical aspects of stem cell banking in a manner understandable to a layperson, but remain detailed enough not to compromise thoroughness of information. Review of scientific publications, laws and ethical guideli
Invasive procedures can be performed safely in children with haemophilia due to the availability of factor VIII/IX for patients without inhibitors. Most guidelines are based on the experiences in adults, but still there is no established consensus on the optimal factor levels or duration of replacement therapy for adults undergoing surgery. Few publications have focused on surgery in children with
There is a class of oligodendrocyte progenitors, called O-2A progenitors, that is characterized by expression of platelet-derived growth factor &agr;-receptors (PDGFR(&agr;)). It is not known whether all oligodendrocytes are derived from these PDGFRalpha-progenitors or whether a subset(s) of oligodendrocytes develops from a different, PDGFR alpha-negative lineage(s). We investigated the re
The focus of education in nursing has changed over time with a decreased focus on biomedicine and an increased focus on nursing science. It is therefore important to investigate whether these changes are also reflected in the students' conceptions and expectations of the programme over time.
Right ventricular rupture, resulting in serious bleeding, is a life-threatening complication associated with negative-pressure wound therapy (NPWT) in cardiac surgery. The use of a rigid barrier between the heart and the sharp sternal edges has been successfully tested on pigs. In the present article, we demonstrate increased safety in NPWT through the use of the HeartShield device.
The role of the newly discovered estrogen receptor GPR30 in islet physiology and pathophysiology is unclear. We examined GPR30 expression in relation to hormone secretion and possible anti-apoptotic effects in isolated mouse islets using the synthetic GPR30 ligand G-1. The mRNA and protein expression of GPR30 was analyzed by qPCR, Western blot and confocal microscopy. Hormone secretion and cAMP co
Background: Smoking prevalence across high-income countries such as the United Kingdom has significantly decreased over the past few decades; this decrease, however, has not occurred uniformly across social strata. The highest concentrations of smokers are currently found in lower-income groups. Lack of access to material resources and differing social norms have been cited as possible causes of t
Experiences of relocation in dementia care from the perspective of six care workers. International Journal of Older People Nursing6, 93-101 doi: 10.1111/j.1748-3743.2010.00246.x Background. Relocation of persons with dementia might be considered when quality of care cannot be sustained due to increasing needs. Relocation has been studied from the aspects of mortality and morbidity. Aim. To explore
Galectin-3 (Gal-3) has been suggested to have both pro- and anti-atherogenic properties. High plasma Gal-3 levels are associated with increased risk for cardiovascular (CV) death. However, it has so far not been investigated if plasma Gal-3 levels can predict the risk for future stroke in patients suffering from carotid atherosclerosis. The aim of this study was to investigate whether Gal-3 could
BACKGROUND Relatively few studies published to date have investigated IVF and cancer risk. In this study we compared the occurrence of cancer in women who gave birth after IVF with all other women who gave birth in the study period. METHODS All women who were treated with IVF and gave birth during the years 1982-2006 in Sweden were identified from all IVF clinics, and the occurrence of cancer in t
The history of spinal cord injuries starts with the ancient Egyptian medical papyrus known as the Edwin Smith Surgical Papyrus. The papyrus written about 2500 B.C.by the physician and architect of the Sakkara pyramids Imhotep, describes "crushed vertebra in his neck" as well as symptoms of neurological deterioration. An ailment not to be treated was the massage to the patients at that time. This f
Little is known about the secular trends in age at spermarche among boys, and the association between body mass index (BMI) and male puberty is controversial.
We aimed to investigate the etiology and clinical management of vaginal bleeding in girls aged 0-9 years and to compare our results with previous publications.
Questions concerning the human–nature relationship have received attention both within contemporary Christianity and Buddhism. Since the twentieth century an interesting and fruitful dialogue has been going on between the two religions. This article describes and discusses possible themes for a Buddhist–Christian dialogue on issues of environmental philosophy. The theoretical starting-point is the
