STUDY DESIGN: Retrospective study. OBJECTIVES: To optimize the radiation doses and image quality for the cone-beam O-arm surgical imaging system in spinal surgery. SUMMARY OF BACKGROUND: Neurovascular compromise has been reported after screw misplacement during thoracic pedicle screw insertion. The use of O-arm with or without navigation system during spinal surgery has been shown to lower the rat

Peri-urban development has in recent years been given increasing attention in different regions all over the world. Peri-urban areas are defined as zones of conflict or competition where new and traditional land uses collide with outer reaches demarcated by daily commuting distances based on common modes of transport into urban cores. In this article an effort to compare peri-urban development in

Abstract Objectives. Glucometabolic disturbances are associated with myocardial dysfunction. Brain natriuretic peptides (BNP) are used for detecting myocardial dysfunction in clinical practice. However, studies on elderly subjects and gender-specific analyses are sparse. Design. We examined cross-sectional associations between Nt-proBNP and 1) fasting plasma glucose (FPG), and 2) categories of glu

Background Patients with inflammatory bowel disease (IBD) often complain of fatigue. Aim To investigate the prevalence and characteristics of fatigue among IBD out-patients in Scandinavia and to provide normative values for fatigue in IBD patients. Methods A cross-sectional study was conducted on 425 IBD patients from six out-patient centres in Denmark, Norway and Sweden. Fatigue was measured usin

Mutations that cause X-linked agammaglobulinemia (XLA) appear throughout the Bruton tyrosine kinase (Btk) sequence, including the pleckstrin homology (PH) domain. To analyze the basis of this disease with respect to protein structure, we studied the relationships between PH domain sequences and structures by comparing sequence-based profiles of physicochemical properties and solvent accessibility

From Plato to Pinker there has been the common belief that the experience of a smell is impossible to put into words. Decades of studies have confirmed this observation. But the studies to date have focused on participants from urbanized Western societies. Cross-cultural research suggests that there may be other cultures where odors play a larger role. The Jahai of the Malay Peninsula are one such

Popular Abstract in Swedish Förmaksflimmer är den vanligaste rytmrubbningen i hjärtat som kräver behandling. Risken att drabbas ökar med åldern och 8% av alla åttioåringar lider av förmaksflimmer. Förmaksflimmer är i sig inte livshotande, men den förhöjda risken för proppbildning i förmaken kan leda till allvarliga komplikationer såsom stroke. Det finns olika behandlingsstrategier för förmaksflimmThis thesis deals with signal processing algorithms for analysis of the electrocardiogram (ECG) during atrial fibrillation (AF). Such analysis can be used for diagnosing patients, and for monitoring and predicting their response to various treatment. The thesis comprises an introduction and five papers describing methods for ECG-based modeling and characterization of AF. Paper I--IV deal with meth

Pathloss is typically modeled using a log-distance power law with a large-scale fading term that is log-normal. However, the received signal is affected by the dynamic range and noise floor of the measurement system used to sound the channel, which can cause measurement samples to be truncated or censored. If the information about the censored samples are not included in the estimation method, as

A straightforward attempt to estimate the influence of the first vertex correction for a homogeneous electron gas is made. The approximation scheme is also tested on a solvable model of a core electron coupled to an electron gas.(12 refs)

The Myc oncoprotein is tightly regulated at multiple levels including ubiquitin-mediated protein turnover. We recently demonstrated that inhibition of Cdk2-mediated phosphorylation of Myc at Ser-62 pharmacologically or through interferon (IFN)-γ-induced expression of p27Kip1 (p27) repressed Myc's activity to suppress cellular senescence and differentiation. In this study we identified an additiona

Golden altars, churches and source criticism: Survey of all known "golden altars" in Scandinavia and a critical analysis of their architctural context and preservation.

Insulin resistance and type 2 diabetes are associated with decreased expression of genes that regulate oxidative phosphorylation in skeletal muscle. To determine whether this defect might be inherited or acquired, we investigated the association of genetic, epigenetic, and nongenetic factors with expression of NDUFB6, a component of the respiratory chain that is decreased in muscle from diabetic p

A collection of 25 articles on medieval archaeology an also presentations of the teaching of medieval archaeology in Europe.

Soil hydraulic properties in field scale porous media are distributed with large spatial heterogeneity. Thus, detailed understanding of micro-physical properties leading to macro-scale heterogeneity is important for generalizing purposes in modeling. Hysteretic water retention properties greatly affect solute transport under unsaturated condition. In this study, laboratory infiltration experiments
