Cancer-associated fibroblasts (CAFs) participate actively in tumor development and affect treatment responses, by among other mechanisms, promoting an immunosuppressive tumor microenvironment. In contrast to normal fibroblasts, reactive CAFs secrete a myriad of immunomodulatory soluble factors at high levels, i.e. growth factors, cytokines, and chemokines, which directly influence tumor immunity and ...

miR-126 has been identified both as a tumor suppressor and an oncogene in different types of cancer. The aim of this study was to investigate the prognostic impact of miR-126-expression in colon cancer patients. Tumor tissue from 452 patients operated for stage I–III colon cancer was retrospectively collected and tissue microarrays were constructed. miR-126 expression was evaluated by in situ ...

The adenosine A_2A receptor (A_2AR) has emerged as a potential non-dopaminergic target for the treatment of Parkinson’s disease and, thus, the non-invasive imaging with positron emission tomography (PET) is of utmost importance to monitor the receptor expression and occupancy during an A_2AR-tailored therapy. Aiming at the development of a PET radiotracer, we herein ...

Background - Fractures in children under 2 years of age are rare, and little has been published on their mechanisms. We aimed at examining the incidence, mechanisms, pattern and fracture characteristics in a large, population-based cohort of otherwise healthy children.<p> <p>Methods - This retrospective, cross-sectional study includes all children aged 0–2 years, attending the Accident and Emergency ...

Background - For young Indigenous people, suicide is one of the leading causes of death, and high rates in Arctic areas indicate serious health- and societal concerns. More knowledge is needed, as suicidal behaviour predictslater death by suicide.<p> <p>Objectives - The objective was to study associations between suicidal thoughts and suicide attempts and socio-demographic, psychosocial, and ...

<p>Aims: The objectives of this study are to identify the proportion and characteristics of people with type 1 and 2 diabetes treated in primary, specialist and shared care and to identify the proportion of persons with type 2 diabetes reaching HbA_1c treatment targets and the clinical risk factors and general practitioner and practice characteristics associated with treatment in specialist ...

<p>Cerebral blood flow (CBF) can be measured with dynamic positron emission tomography (PET) of ¹⁵O-labeled water by using tracer kinetic modelling. However, for quantification of regional CBF, an arterial input function (AIF), obtained from arterial blood sampling, is required. In this work we evaluated a novel, non-invasive approach for input function prediction based on machine learning ...

<i>Background</i> - Population mean GFR is lower in older age, but it is unknown whether healthy aging is associated with preserved rather than lower GFR in some individuals.<br><br> <i>Methods</i> - We investigated the cross-sectional association between measured GFR, age, and health in persons aged 50–97 years in the general population through a meta-analysis of iohexol clearance measurements ...

Growth hormone (GH) deficiency is associated with cognitive decline which occur both in normal aging and in endocrine disorders. Several brain areas express receptors for GH although their functional role is unclear. To determine how GH affects the capacity for learning and memory by specific actions in one of the key areas, the hippocampus, we injected recombinant adeno-associated viruses (rAAVs) ...

<i>Purpose</i>: Lipopolysaccharides (LPS) are presumed to contribute to the inflammatory response in sepsis. We investigated if extracorporeal Alteco LPS Adsorber for LPS removal in early gram-negative septic shock was feasible and safe. Also, effects on endotoxin level, inflammatory response, and organ function were assessed.<br><br> <i>Methods</i>: A pilot, double-blinded, randomized, Phase ...
