Background: Prostate-specific membrane antigen (PSMA) radiotracers such as [18F]PSMA-1007 used with positron emission tomography-computed tomography (PET-CT) is promising for initial staging and detection of recurrent disease in prostate cancer patients. The block-sequential regularization expectation maximization algorithm (BSREM) is a new PET reconstruction algorithm, which provides higher image

A deeper knowledge of the architecture of the peripheral nerve with three-dimensional (3D) imaging of the nerve tissue at the sub-cellular scale may contribute to unravel the pathophysiology of neuropathy. Here we demonstrate the feasibility of X-ray phase contrast holographic nanotomography to enable 3D imaging of nerves at high resolution, while covering a relatively large tissue volume. We show

The task of assessing the extent of a gas release during pipeline emergency situations is challenging. Traditional methodologies for risk analysis require significant computer capabilities and time; factors that have traditionally made emergency response teams unable to use gas dispersion modelling during real incidents.

The Norwegian Offshore Regulator requires top executives to confirm the safety of their installations with particular focus on established barriers towards large scale accidents. StatoilHydro has implemented a structured approach for assessing the technical safety condition of its key barriers. Performance Standards (PS's) are defined for each barrier and each PS defines a set of Performance Requi

Statoil has implemented a structured approach for assessing the condition of the safety barriers on their processing facilities as a key measure to control and reduce major accident risk. The TTS (Teknisk Tilstand Sikkerhet, Norwegian for technical condition safety) methodology is developed with a strong focus on assessing the actual conditions of the technical safety barriers in place to manage m

Chills and vomiting have traditionally been associated with severe bacterial infections and bacteremia. However, few modern studies have in a prospective way evaluated the association of these signs with bacteremia, which is the aim of this prospective, multicenter study. Patients presenting to the emergency department with at least one affected vital sign (increased respiratory rate, increased he

Cell replacement is a long-standing and realistic goal for the treatment of Parkinsonʼs disease (PD). Cells for transplantation can be obtained from fetal brain tissue or from stem cells. However, after transplantation, dopamine (DA) neurons are seen to be a minor component of grafts, and it has remained difficult to determine the identity of other cell types. Here, we report analysis by single-ce

I denna rapport redovisas delresultat från ett treårigt forskningsprojekt somfinansieras av AFA-försäkringar. Projektet heter ”Skolledares arbetsmiljö: Ettprojekt om organisatoriska förutsättningar, stressrelaterad psykisk ohälsa,personalrörlighet och förbättringspotential”. Projektet är ett tvärvetenskapligtsamarbete mellan Avdelningen för arbets- och miljömedicin (AMM) ochInstitutionen för psyko

Patients with chronic pancreatitis have an impaired quality of life and are at risk for several long-term complications. It is important to diagnose and treat these patients to minimize the effects of the disease. Clinical manifestations of chronic pancreatitis include a wide range of symptoms and patients are managed differenth between medical centers. In recent years, there have been improvement

OBJECTIVES: Chronic lung allograft dysfunction including Bronchiolitis obliterans syndrome (BOS) is common after lung transplantation. Histologically, BOS is recognized as fibrotic lesions with accumulated extracellular matrix (ECM) in small airways. Lung fibroblasts are major producers of ECM and vascular endothelial growth factor (VEGF). In this study we hypothesize that VEGF is involved in BOS

Organisms in the wild are faced with multiple threats and a common response is a change in behaviour. To disentangle responses to several threats, we exposed two differently sized species of the freshwater invertebrate Daphnia to solar ultraviolet radiation (UVR) and predation from either moving pelagic or benthic ambush predators. Using an advanced nanotechnology-based method, we tracked the thre

Introducing biobased polymers from renewable sources for use as high-performance thermoplastics with high demands on mechanical rigidity, transparency, thermal stability, as well as good processability, is a significant challenge. In the present work we have designed and prepared a rigid biobased bis-spirocylic diol by di-cycloketalization of a bicyclic diketone (cis-bicyclo[3.3.0]octane-3,7-dione

Large-scale science research facilities, such as those for investigation into the smallest components of physical matter, often consist of buildings with quite extraordinary features as regards shape and scale. These architectures are semiotically interesting in several ways: they have extraordinary outer forms that reflect the their inner activities; they require forms of mediation and planning t

The Compex detector is an electrically cooled, composite germanium detector that uses four coaxial, cubic-shaped, single-encapsulated germanium crystals. This novel detector allows for new heights in photon detection efficiency in decay spectroscopy setups using box-shaped vacuum chambers. Its spectroscopic performance and detection efficiency is evaluated by means of source measurements. Motivate

A first performance test of the Coulomb excitation multipolarimetry (Coulex-multipolarimetry) method is presented. It is based on a 85Br πp3/2 → πp1/2 spin-flip experiment performed as part of the PreSPEC-AGATA campaign at the GSI Helmholtzzentrum für Schwerionenforschung (GSI). Via determination of background levels around the expected 85Br excitations as well as measured 197Au excitations, an up

New physics opportunities are opening up by the Advanced Gamma Tracking Array, AGATA, as it evolves to the full 4π instrument. AGATA is a high-resolution γ-ray spectrometer, solely built from highly segmented high-purity Ge detectors, capable of measuring γ rays from a few tens of keV to beyond 10 MeV, with unprecedented efficiency, excellent position resolution for individual γ-ray interactions,
