Background:Computed tomographic angiography (CTA) may require a non-contrast enhanced dataset for the diagnostic workup. By using dual-energy acquisition, it is possible to obtain a virtual non-contrast-enhanced (VNC) dataset, thereby possibly eliminating the non-contrast acquisition and reducing the radiation dose.Purpose:To compare image quality of VNC images reconstructed from arterial phase du
BACKGROUND: Long QT syndrome (LQTS) is caused by the abnormal function of ion channels, which may also affect atrial electrophysiology and be associated with the risk of atrial fibrillation (AF). However, large-scale studies of AF risk among patients with LQTS and its relation to LQTS manifestations are lacking. We aimed to assess the risk of AF and its relationship to the LQTS genotype and the lo
Background: Widespread implementation of Alzheimer's disease biomarkers in routine clinical practice requires the establishment of standard operating procedures for pre-analytical handling of cerebrospinal fluid (CSF). Methods: Here, CSF collection and storage protocols were optimized for measurements of β-amyloid (Aβ). We investigated the effects of (1) storage temperature, (2) storage time, (3)
Reason(s) for writing and research problem(s): This article analyzes the experiences retold by former concentration camp detainees who were placed in concentration camps like civilians at the beginning of the Bosnian war in the 1990s. Aims of the paper (scientific and/or social): The article aims to describe the recounted social interaction rituals after time spent in a concentration camp as well
A new global atmospheric carbon dioxide (CO2) real-time forecast is now available as part of the pre- operational Monitoring of Atmospheric Composition and Climate – Interim Implementation (MACC-II) service us- ing the infrastructure of the European Centre for Medium- Range Weather Forecasts (ECMWF) Integrated Forecast- ing System (IFS). One of the strengths of the CO2 fore- casting system is that
Purpose: Muda is a Japanese term literally meaning futility, uselessness, idleness, superfluity, waste, wastage or wastefulness. The term was introduced by the Japanese engineer Taiichi Ohno of Toyota Motor Corporation in the 1960s. Therefore, reducing and minimizing Muda is an effective way to increase the operational efficiency and productivity of an organization’s processes. In turn, the techni
Abstract Background: Cardiac resynchronization therapy (CRT) is effective, but only 60-70% of patients benefit from the therapy. Despite numerous implantations, identification of predictive factors for response is still a challenge. We sought to assess the correlation of echocardiographic and clinical response to baseline demographics in relation to change in NT-proBNP levels at 6 months. Methods:
Denna avhandling undersöker vetenskapens roll i den politiska processens tidiga stadier. Detta görs genom att studera hur "geoengineering" kommer upp på den politiska agendan. Begreppet ”geoengineering” används även på svenska och beskriver en uppsättning idéer om hur man stabiliserar den globala temperaturen genom att ingripa i jordens miljösystem. Begreppet mötte stark skepsis i det vetenskapligThis thesis examines the role of science in the earliest stages of the political process. It does this by studying the emergence of ‘geoengineering’ on the political agenda. The term describes a set of ideas on how to stabilize global temperature by intervening into the Earth’s natural systems, and was subject to a strong taboo in the scientific community until the mid-2000s. Yet within a decade,
The acceleration of DNA sequencing in samples from patients and population studies has resulted in extensive catalogues of human genetic variation, but the interpretation of rare genetic variants remains problematic. A notable example of this challenge is the existence of disruptive variants in dosage-sensitive disease genes, even in apparently healthy individuals. Here, by manual curation of puta
Specific alterations (mutations, deletions, insertions) of virus genomes are crucial for the functional characterization of their regulatory elements and their expression products, as well as a prerequisite for the creation of attenuated viruses that could serve as vaccine candidates. Virus genome tailoring can be performed either by using traditionally cloned genomes as starting materials, follow
The idea for nature based research design emerged in preparation of a workshop and subsequent exhibition regarding minimal surfaces, supervised by Andreas Hopf, Senior Lecturer at Lund University School of Industrial Design, and supported by Prof. Dr. Konrad Polthier (Chair Mathematical Geometry Processing, FU Berlin) at the DESIGNMAI digital crafts event in Berlin in 2007, for which Swedish desig
The thesis deals with ritual remembrance ceremonies enacted in the three towns of Mostar, Jajce and Višegrad in BiH. The Old Bridge in Mostar, the Bridge over the Drina in Višegrad and the AVNOJ Museum in Jajce all carry a material presence that influences everyday life in these localities. Through ethnographic fieldwork, insights into local practices in relation to those World Heritage Sites are
This thesis is about self-knowledge, self-regulation and self-control. All three of these terms are easily understandable, and apply to situations in our daily lives (like misjudging one’s own competence at retiling the bathroom floor, or feeling the anxiety and thrill of doing unsupervised work, or guiltily hitting the snooze-button for the fifth time, and missing half a day of school). The five
Popular Abstract in Swedish Okontrollerad proliferation och invasion är två viktiga egenskaper i tumörutveckling och tumörprogression. Tidigare studier har visat att invaderande tumörceller i kolorektalcancer har låg proliferation parallellt med en uppreglering av tumörsuppressorn p16. Vi undersökte p16-uttrycket och proliferation i basalcellscancer och skivepitelcancer i huden, tumörer som är lokUncontrolled proliferation and invasion are two characteristics in tumour development and progression. Previous studies have shown that invading tumour cells in colorectal cancer have low proliferation in parallel to upregulation of the tumour suppressor p16. We set out to detail the p16 expression and proliferation in basal cell carcinoma and squamous cell carcinoma of the skin, tumours that are
