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

33Background: PSMA PET has been shown to detect more metastasis and alter management at biochemical recurrence (BCR), but it remains to be determined that it changes oncologic outcome. We assessed the quantitative parameters on 18F-DCFPyL PET at BCR and evaluated their association with tumor volume, metastatic locations with the subsequent biochemical progression free survival (bPFS). Methods: Thi

Heart failure (HF) is a major contributor to global morbidity and mortality. While distinct clinical subtypes, defined by etiology and left ventricular ejection fraction, are well recognized, their genetic determinants remain inadequately understood. In this study, we report a genome-wide association study of HF and its subtypes in a sample of 1.9 million individuals. A total of 153,174 individual

Climate change is increasingly recognized as a major security concern, with drought–migration–conflict linkages attracting significant attention in both policy and research. While some narratives portray drought as a direct driver of migration and conflict, evidence shows a far more complex relationship: climate stress can lead to more migration in some contexts and less in others, with internal m

Background: Mammography screening programmes have been widely implemented across European countries over the past 40 years with the main aim to detect breast cancer earlier and thereby reduce breast cancer mortality. This study aimed to analyse and compare changes over time in breast cancer incidence, by stage at diagnosis, and breast cancer mortality across countries in relation to the timing of

1996 infördes miljöersättning för skötsel av landskapselement som ligger i eller i anslutning till åkermark i Sverige. Landskapselement i jordbrukslandskapet såsom öppna diken, stenmurar, åkerrenar och åkerholmar är viktiga småbiotoper för många djur- och växtarter. Idag (2013) kan miljöersättning för kultur- och naturmiljöer i odlingslandskapet (även kallat kulturmiljöstöd) sökas av lantbrukare sIn 1996, an agri-environmental support scheme was introduced in Sweden to compensate farmers for the maintenance of landscape elements located in or adjacent to cropland. Landscape elements in the agricultural landscape, for example ditches, stone walls, field margins and field islets, are important small biotopes for many animal and plant species. Today, farmers who remove bushes and trees (with

The urbanization of landscapes and the increase in impervious land cover materials is known to cause significant changes in the landscape's thermal properties, typically leading to urban heat island (UHI). Although previous studies have investigated the impacts of land cover land use (LULC) and other factors on the urban land surface temperature (LST), the results of such studies are mixed. For in

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

Background: Combination lipid-lowering therapy (LLT) after myocardial infarction (MI) achieves lower low-density lipoprotein cholesterol (LDL-C) levels and better cardiovascular outcomes vs statin monotherapy. As a result, global guidelines recommend lower LDL-C but, paradoxically, advise treatment through a stepwise approach. Yet the need for combination therapy is inevitable as <20% of patients

Introduction: The rate of vaginal hysterectomies is declining globally. We investigated surgical techniques, outcomes, and costs in a large national cohort of benign hysterectomies with prerequisites for vaginal surgery. Material and Methods: A retrospective register-based cohort study with benign hysterectomies in the Swedish GynOp registry 2014–2023 (n = 17 804). Inclusion criteria were non-prol

MAX-lab is a national synchrotron radiation facility in Lund. Nowadays, the MAX project consist of three facilities (three storage rings). A new storage ring is needed to improve material science, such as nanotechnology. MAX IV, also in Lund, will be 100 times more efficient than already existing synchrotron radiation facilities. The storage ring is controlled by a large number of magnets that are

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

Dealing with water diffuse pollution is a major problem for watershed managers. This problem raises many complicated questions, which are important to answer in order to reach water environment protection goals. This study suggested some possible answers for the country of Lithuania. Among them were the identification of critical source areas, the identification of sensitive areas and the applicat

Associate senior lecturer My recent research has focused on the structure and photoluminescence of assemblies (superlattices) of lead halide perovskite nanocrystals. In Lund, I aim to understand and control the cooperative properties of nanocrystals with the help of materials engineering, laser spectroscopy, and theory.

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

Objective To compare, in young active adults with an acute anterior cruciate ligament (ACL) tear, the mid-term (five year) patient reported and radiographic outcomes between those treated with rehabilitation plus early ACL reconstruction and those treated with rehabilitation and optional delayed ACL reconstruction. Design Extended follow-up of prospective randomised controlled trial. Setting Ortho

Sex hormone-binding globulin (SHBG) is a glycoprotein responsible for the transport and biologic availability of sex steroid hormones, primarily testosterone and estradiol. SHBG has been associated with chronic diseases including type 2 diabetes (T2D) and with hormone-sensitive cancers such as breast and prostate cancer. We performed a genome-wide association study (GWAS) meta-analysis of 21,791 i

Introduction Many kinds of footwear are used for various purposes in the workplace in Japan. Careful selection of footwear is needed to protect workers from coldness and to keep the performance of workers in cold workplace where employees have to work under -20℃. On the other hand, safety boots with high heat conductivity from foot to outside are needed for the workers in hot environments. But the
