Inter-vehicle communication (IVC) systems (i.e., systems not relying on road-side infrastructure) have the potential to radically improve the safety, efficiency and comfort of every day road-travel. Their main advantage is that they bypass the need for expensive infrastructure; their major drawback is the comparatively complex network- ing protocols and the need for a significant penetration befor
Background: Prostate-specific antigen (PSA) has modest specificity for prostate cancer. A panel of four kallikrein markers (total PSA, free PSA, intact PSA, and kallikrein-related peptidase 2) is a highly accurate predictor of biopsy outcome. The clinical significance of biopsy-detectable cancers in men classified as low-risk by this panel remains unclear. Methods: The Malmo Diet and Cancer study
This study attempts to develop a method for the simulation of surface flow paths on a digital elevation model (DEM). The objective is to use a facet-based algorithm to estimate the surface flow paths on a raster DEM. A grid DEM was used to create a triangular facet network (TFN) over which the surface flow paths were determined. Since each facet in the network has a constant slope and aspect, the
Resonant in situ photoemission from Mn 3d states in Ga1-xMnxAs is reported for Mn concentrations down to the very dilute level of 0.1%. Concentration-dependent spectral features are analyzed on the basis of first-principles calculations for systems with selected impurity positions as well as for random alloys. Effects of direct Mn-Mn interaction are found for concentrations as low as 2.5%, and are
Background: For many years there has been a debate as to which is the method of choice in treating patients with esophageal perforation. The literature consists mainly of small case series. Strategies for aiding patients struck with this disease is changing as new and less traumatic treatment options are developing. We studied a relatively large consecutive material of esophageal perforations in a
Background: Animal experimental studies and previous randomized trials suggest an improvement in mortality and neurological function with temperature regulation to hypothermia after cardiac arrest. According to a systematic review, previous trials were small, had a risk of bias, evaluated select populations, and did not treat hyperthermia in the control groups. The optimal target temperature manag
Venous thromboembolism (VTE) clusters in families, but the familial risk of VTE has only been determined in first-degree relatives. This nationwide study aimed to determine the familial risk of VTE in first-, second- and third-degree relatives of affected individuals. The Swedish Multi-Generation Register was linked to Hospital Discharge Register data for the period 1987-2009. This was a case-coho
Aim: To investigate health-related quality of life (HRQoL) in young persons with limb reduction deficiency (LRD). Methods: One hundred and forty children with LRD aged 8-16 answered the DISABKIDS questionnaire for children with chronic health conditions. Of their parents, 137 answered a corresponding questionnaire concerning their child. Results: Compared to reference data from children with other
Recension av Kazimiera Ingdahl: Icke helt och hållet skall jag dö. Den ”judiska frågan” i Polen.
Dynamic chromatin structure is a fundamental property of gene transcriptional regulation, and has emerged as a critical modulator of physiological processes during cellular differentiation and development. Analysis of chromatin structure using molecular biology and biochemical assays in rare somatic stem and progenitor cells is key for understanding these processes but poses a great challenge beca
Popular Abstract in Swedish Östrogen är ett av de viktigaste/ mest studerade kvinnliga könshormonerna som styr utvecklingen av våra fortplantningsorgan och deras reproduktionsförmåga. Östrogen påverkar dessutom många av kroppens andra organ, bland annat hjärnan, skelettet, och hjärt-kärlsystemet. Mängden östrogen som finns i kroppen varierar vanligtvis under menstruationscykeln och med kvinnans ålEstrogen effects are mediated either through genomic action involving the classical estrogen receptors, estrogen receptor alpha (ERα) and beta (ERß), which function as transcription factors in the nucleus, or through rapid non-genomic action via receptors associated with plasma membrane. Recently, a member of the G protein-coupled receptor family was ascribed estrogen receptor properties and propo
At the end of the eighteenth century, Edward Gibbon described the antiquarian scholars of previous generations as men of “profound learning and easy faith.” His exemplar was the Swedish polymath Olof Rudbeck, who in a series of frantic and combative tomes sought to portray Sweden as the model for Plato’s Atlantis and the seething cultural cauldron from which Western civilization had emerged. A Pil
We consider steady symmetric gravity water waves on finite depth with constant vorticity and a monotone surface profile between crests and troughs. The problem is transformed into one concerning the vertical velocity. A representation formula for the stream function in terms of the surface and the vorticity is presented, and we show that the surface can be determined from the vertical velocity.
The aim of this study is to present diagnostic patterns, diagnostics used and antibiotic treatment in relation to guidelines in 3 repeated diagnosis-prescription studies conducted simultaneously in general practice in 5 Swedish counties, during 1 week in November 2000, 2002 and 2005. General practitioners (GPs) at the participating health centres were asked to complete a form for all patients with
The double sided silicon strip detector (DSSSD) is a segmented silicon detector commonly used in the fields of high energy physics and nuclear physics. This type of detector is used for analysis of reactions produced by charged particles. This makes it well suited for a number of analytical methods commonly used in ion beam analysis (IBA), such as Rutherford Backscattering (RBS) and elastic recoil
Popular Abstract in Swedish Allt liv på jorden är beroende av energi. Växter och vissa bakterier kan fånga och utnyttja solens energi för att bygga upp sina celler och dess delkomponenter som fetter, sockerarter och proteiner. Den energi som på så sätt blir bunden i dessa molekyler kan användas av djur och människor genom att vi konsumerar dem. För att energin skall kunna utnyttjas av kroppen måstSepsis is a devastating disease that is caused by the host’s response to an overwhelming infectious process. As sepsis progresses, organs distant from the site of infection become affected and sepsis-induced multiple organ failure ensues. An impaired immunologic response, including dysfunctional peripheral blood immune cells has been described as part of the septic syndrome. Mitochondrial dysfunct
