Syfte: Syftet är att undersöka huruvida Sveriges officiella CO2-data från trans-portsektorn är internationellt rimliga åren 1990-2004. Sverige har uppvi-sat en internationellt lyckad reduktion av CO2-utsläpp samtidigt som Väg- och transportforskningsinstitutet visar att Sveriges CO2-utsläpp från vägtrafiken kan vara dubbelt så höga som rapporterat. Metod: Undersökningen sker genom en jämförelse me
Popular Abstract in Swedish I gruppen huvudhalscancer ingår tumörer i övre luftvägar och svalg. Riskfaktorer för huvudhalscancer är rökning och alkoholöverkonsumtion. Under de senaste 20-30 åren har det skett en påtaglig ökning av insjuknandet, 4-5% per år, i det som kallas orofaryngeal cancer. Orofaryngeal cancer utgår från mellansvalget; mandlar, tungbas och mjuka gommen. Ökningen sammanfaller mThe treatment for head and neck squamous cell carcinoma (HNSCC) is surgery or (chemo)radiotherapy +/- surgery. Side effects related to therapy are long lasting and adversely affects quality of life. The incidence of oropharyngeal cancer is increasing and patients commonly present an advanced tumour stage with neck metastases at the time of diagnosis. The treatment protocol previously comprised rad
Jämförelse mellan småfåglars revir i stad och i skog Sedan människan började bygga civilisationer med städer för tiotusen år sedan har andra organismer ställts inför ett val, att flytta på sig, att gå under eller att anpassa sig. Staden är ur ett biologiskt perspektiv en mycket ny miljö och det kan vara svårt att säga hur miljön påverkar de som väljer att bosätta sig här. Många djur har dock lyc
This study investigated the feasibility of targeting the free, unbound forms of prostate-specific antigen (fPSA) for in vivo imaging of prostate adenocarcinomas (PCa), as PSA is produced and secreted at abundance during every clinical stage and grade of PCa, including castration-resistant disease. We injected (125)I-labeled monoclonal antibody PSA30 (specific for an epitope uniquely accessible on
Popular Abstract in Swedish I högrisksystem såsom sjukvården är det frestande att härleda såväl framgång som motgång till enskilda individer. Vi prisar hjälten Dr. House för framgångssagor och vi drar syndabocken SOS-sköterskan inför domstol för att inte ha uppfattat allvaret i en specifik situation. Den enskildes professionalitet, erfarenhet och klokskap används som förklaringsmodeller för framgåThe main aim of the research is to explore different aspects of organisational resilience in escalating situations, with an investigation of both theoretical and practical implications. From the platform of an explorative approach, this study makes use of naturalistic research in the domain of health care and experimental simulation studies, in order to establish a broad theoretical framework vis-
Metal-assisted chemical etching (MACE) is a cheap and scalable method that is commonly used to obtain silicon nano- or microwires but lacks spatial control. Herein, we present a synthesis method for producing vertical and highly periodic silicon microwires, using displacement Talbot lithography before wet etching with MACE. The functionalized periodic silicon microwires show 65% higher PEC perform
Background and aims: Active aging is the process through which people strive to maintain wellbeing when growing old. Addressing the lack of research on active aging in the context of housing, the aim was to describe active aging among people aged 55 and older considering relocation and investigate whether perceived housing moderates the relationship between functional limitations and active aging.
Air pollution in urban environments exhibits large spatial and temporal variations due to high heterogeneous air flow and emissions. To address the complexity of local air pollutant dynamics, a comprehensive large-eddy simulation using the PALM model system v6.0 was conducted. The distribution of flow and vehicle emitted aerosol particles in a realistic urban environment in Malmö, Sweden, was stud
Identifying key molecular pathways and genes involved in the response to urban pollutants is an important step in furthering our understanding of the impact of urbanisation on wildlife. The expansion of urban habitats and the associated human-introduced environmental changes are considered a global threat to the health and persistence of humans and wildlife. The present study experimentally invest
Mesenteric duct chylomicrons labelled with [3H]arachidonic (20:4) and [14C]linoleic (18:2) acid were injected intravenously into essential fatty acid-deficient (EFAD) and control rats. The rats were killed after 5, 10, 20 and 240 min, and serum and different organs were analysed for radioactivity of different lipid classes. 3H and 14C in the triacylglycerol (TG) and phosphatidylethanolamine (PE) f
Background: It is unclear whether there are causal associations between blood lipids, statin use and cancer risks. Under certain assumptions, Mendelian randomization analysis of a genetic marker for an exposure eliminates reverse causation and confounding. Methods: We applied Mendelian randomization analysis to genetic scores, comprising 26–41 single-nucleotide polymorphisms (SNPs), as instrumenta
BackgroundPrevention of child obesity is an international public health priority and believed to be effective when started in early childhood. Caregivers often ask for an early and structured response from health professionals when their child is identified with overweight, yet cost-effective interventions for children aged 2–6 years and their caregivers in Child Health Services are lacking.Object
Dysregulation of cytokines in the bone marrow microenvironment promotes acute myeloid leukemia cell growth. Due to the complexity and low throughput of in vivo stem-cell based assays, studying the role of cytokines in the bone marrow niche in a screening setting is challenging. Herein, we developed an ex vivo cytokine screen using 11 arrayed molecular barcodes, allowing for a competitive in vivo r
Generating functional and perfusable micro-vascular networks is an important goal for the fabrication of large and three-dimensional tissues. Up to now, the fabrication of micro-vascular networks is a complicated multitask involving several different factors such as time consuming, cells survival, micro-diameter vasculature and strict alignment. Here, we propose a technique combining multi-materia
There have been previous studies comparing experimental methods for the purpose of capturing gaseous yields at a range of global equivalence ratios. However, no work has investigated the capability of the open controlled atmosphere cone calorimeter for collecting such data where its two modes of operation are directly compared. The aim of this study is to compare carbon monoxide yields collected u
Acoustophoresis has become a powerful tool to separate microparticles and cells, based on their material and biophysical properties, and is gaining popularity in clinical and biomedical research. One major application of acoustophoresis is to measure the compressibility of cells and small organisms, which is related to their contents. The cell compressibility can be extracted from the acoustic mob
Purpose: Although persistent offenders with histories of imprisonment and violence have disproportionate high rates of psychiatric disorders, little is known of their psychiatric healthcare utilization (HCU) and HCU-associated factors. This study aimed to explore psychiatric HCU, psychiatric morbidity, and psychotropic prescription drugs in violent offenders with a history of incarceration. Method
The Eurasian spruce bark beetle, Ips typographus, is a major pest, capable of killing spruce forests during large population outbreaks. Recorded dispersal distances of individual beetles are typically within hundreds of meters or a few kilometers. However, the connectivity between populations at larger distances and longer time spans and how this is affected by the habitat is less studied, despite
Aims: According to Braak's hypothesis, it is plausible that Parkinson's disease (PD) originates in the enteric nervous system (ENS) and spreads to the brain through the vagus nerve. In this work, we studied whether inflammatory bowel diseases (IBDs) in humans can progress with the emergence of pathogenic α-synuclein (α-syn) in the gastrointestinal tract and midbrain dopaminergic neurons.
