Importance: This follow-up study of extremely preterm (EPT) children (<27 weeks' gestational age [GA] at birth) revealed major eye and visual problems in 37.9% (147 of 388) of all EPT infants and in 55.4% (67 of 121) of the most immature subgroups at 6.5 years of age. These major eye and visual problems were strongly associated with treatment-requiring retinopathy of prematurity (ROP).Objectives:

The structural heterogeneity of tumor tissue can be probed by diffusion MRI (dMRI) in terms of the variance of apparent diffusivities within a voxel. However, the link between the diffusional variance and the tissue heterogeneity is not well-established. To investigate this link we test the hypothesis that diffusional variance, caused by microscopic anisotropy and isotropic heterogeneity, is assoc

IMPORTANCE Fluid overload occurring as a consequence of overly aggressive fluid resuscitation may adversely affect outcome in hemodynamically unstable critically ill patients. Therefore, following the initial fluid resuscitation, it is important to identify which patients will benefit from further fluid administration. OBJECTIVE To identify predictors of fluid responsiveness in hemodynamically uns

Retinitis pigmentosa is a group of inherited retinal degenerative diseases characterized by the loss of photoreceptors and vision for which no effective treatment is available. Several animal models of retinitis pigmentosa are used to elucidate its pathogenesis and to devise therapies. The retinal degeneration (rd1) mouse is one such animal model in which rod-specific phosphodiesterase (PDE) is in

Tillväxtverket har identifierat ett finansiellt gap för mindre och nystartade företag i Sverige. Orsaken till detta är att dessa företag har svårigheter med kapitalanskaffning, vilket ofta är essentiellt för företags överlevad. Problematiken med kapitalanskaffning beror delvis på att banker och traditionella kreditinstitut ser stora risker med att låna ut pengar till mindre och nystartade företag.The Swedish Agency for Economic and Regional Growth has identified a financial gap amongst startups and smaller companies in Sweden. The gap is a result of a difficulty for these companies to raise capital, which often is a necessity for companies in order to survive. The difficulty of raising capital is due to the fact that banks and traditional credit institutions are at high risk when lending m

How the IGHV upstream sequences look like? The antibody, also called immunoglobulin (lG), can identify and bind specifically to antigens such as bacteria, viruses, and other disease-causing organisms. Its high variety is achieved by the selection and recombination of genes from normal full-length genomic genes. The antibody contains two identical heavy chains and two identical light chains. What

Popular science summary: A growing body of evidence shows that tumors consist of rare cancer stem cells (CSCs), precursor cells and differentiated tumor cells. CSCs are today thought to be the main culprit in the tumor origin, progression, recurrence and resistance to therapy. The origin of CSC is enigmatic; however, it has been suggested that CSCs can arise from any type of cells and the underly

With an increasingly population and urbanization, the solid waste management have become a major challenge for local authorities in developing countries all over the world. The local authorities must improve their waste management in order to minimize the negative effects of solid waste and to avoid future land use conflicts. At the same time the economical resources are limited and solid waste ma

Dwarf galaxies are a key component in understanding the evolution of galaxies and provide tests on the standard cosmological $\Lambda$ Cold Dark Matter model. According to the formation hierarchy, dwarf galaxies are the pieces that create all galaxies. Our current understanding of dwarf galaxies faces discrepancies between theory and observations. These problems are mostly due to incompleteness in

The release of carbon dioxide (CO2) from inland waters plays an important role in the global carbon cycle. Yet, there are uncertainties related to estimating riverine CO2 evasion (FCO2), especially in data scarce regions such as the Tibetan Plateau. It is unclear how global change in the form of climate warming and anthropogenic disturbance affects emissions. This study reports annual CO2 fluxes a

Background: Magnetic resonance imaging (MRI) is recommended by guidelines to evaluate the severity of brain ischemia after cardiac arrest for functional outcome prediction. However, standardized assessment criteria are lacking. We have developed a semi-quantitative Cardiac Arrest Brain Ischemia (CABI) score to assess the extension of brain ischemia on MRI. Objectives: To evaluate the prognostic pe

Background: The routine use of sedation and analgesia during post-cardiac arrest care and its association with clinical outcomes remain unclear. This study aimed to describe the use of sedatives and analgesics in post-cardiac arrest care, and evaluate associations with good functional outcome, survival, clinical seizures, and late awakening. Methods: This was a post hoc analysis of the TTM2-trial,

Background: There has been a recent global movement toward certification of “green” buildings. The Sweden Green Building Council currently supports four sustainable building certification schemes: LEED, BREEAM, Miljöbyggnad, and GreenBuilding. These systems use widely disparate criteria to assess building sustainability and are adopted at differing rates within the nation. They are also constantly

Varje år diagnostiseras i Sverige ungefär 1100 personer med cancer i huvudhalsregionen. Typiska diagnoser är tungcancer, läppcancer och cancer i struphuvudet. I och runt om munhålan finns det stora skillnader i densitet mellan till exempel vävnad och tänder och vävnad och tandlagningar. I detta arbete så har effekterna av ett antal olika tandlagningsmaterial på dosberäkningarna undersökts. För a"Introduction: Around 1.000 people are diagnosed with head and neck cancer in Sweden every year. Radiotherapy is often used to treat these tumors. When irradiating patients in the head and neck area there are some problems. One of these problems is the large difference in density between the oral tissue and dental materials. Another problem is the image artifacts due to high-density materials

Monte Carlo-simuleringar har fått en ökad betydelse som forskningsverktyg inom nuklearmedicinsk bildgivning eftersom man på ett mycket kontrollerat sätt kan studera nästan vad man vill. I denna studie har datorsimuleringar av ett PET-system gjorts med ett program som heter GATE. PET (Positron Emission Tomography) är en nuklearmedicinsk bildgivningsteknik som används mer och mer inom sjukvården sIntroduction: Monte Carlo simulation is a powerful tool in research in the field of nuclear medicine imaging and there is a wide area of applications. The purpose of this work was (1) to understand the basics of the Monte Carlo simulation software Geant4 Application for Tomographic Emission (GATE); (2) to create a model of Philips Gemini TF PET/CT system; (3) to run a number of simulations to comp

In my paper I have emanated from the question when a refusal to deal by an undertaking in a dominant position constitutes an abuse according to article 82 EC Treaty. Article 82 of The Consolidated version of the Treaty establishing the European Community, signed in Rome 1957, incorporating the changes made by the Treaty of Amsterdam on 2 October 1997, OJ 1997 C340, pp. 173-308, hereafter referred

INTRODUCTION: Since the last two decades, there has been a dramatic rise in caesarean sections (CS) throughout the world. This increase has been seen even in Europe, where rates vary significantly from 17% in Northern Europe to 56% in the South. Although, CS can be a lifesaving intervention when medically necessary, non-essential CS are associated with short- and long-term complications for both t
