The DyDOC model simulates the C dynamics of forest soils, including the production and transport of dissolved organic matter (DOM), on the basis of soil hydrology, metabolic processes, and sorption reactions. The model recognizes three main pools of soil C: litter, substrate (an intermediate transformation product), and humic substances. The model was used to simulate the behavior of C in the 0 ho
Juvenile bird migrants are generally believed to use a clock-and-compass migratory orientation strategy. According to such a strategy migrants accomplish their migration by flying a number of successive flight steps with direction and number of steps controlled by an endogenous programme. One powerful way of testing this is by comparing predictions from a model of such a strategy with observed pat
Background Complement factor C3 and C4 have been associated with atherosclerosis and cardiovascular risk factors. This study explored whether plasma levels of C3 and C4 are risk factors for the incidence of cardiovascular disease (CVD). Design A population-based prospective study of 5850 initially healthy men, 28-61 years old at baseline. Methods Plasma levels of C3 and C4 were analysed at the bas
OBJECTIVES: Animal studies have shown that persistent organochlorine compounds (POC) impair normal bone metabolism and result in increased bone fragility. These findings may have health implications for POC-exposed human populations. The aim of the present study was to assess the impact of POC-contaminated fish on the self-reported fracture incidence of Swedish fishermen and their wives. METHODS:
Contemporary English as a foreign language (EFL) classrooms in upper secondary schools in Sweden make frequent use of receptive media such as movies and television to facilitate language learning. The more interactive medium of video games is seldom used for the same purpose, despite previous research indicating that the added layer of interactivity can bring benefits such as improvements to vocab
Background Subclinical cobalamin deficiency is common in the elderly, but the sensitivity and specificity of serum total cobalamin for this diagnosis is poor. Serum holotranscobalamin (holoTC), a measure of biologically available cobalamin, is considered a better marker for early cobalamin depletion than total cobalamin. However, in elderly populations, health-related reference intervals for holoT
BackgroundObesity is commonly diagnosed using BMI, which does not capture total adiposity or fat distribution, as highlighted by the recent Lancet D&E Commission report. We assessed the prognostic value of an adiposity-based classification combining body fat percentage (BF%) and waist circumference (WC) in relation to cardiometabolic and kidney outcomes and evaluated its concordance with BMI.M
Background: Expression of CD25, the IL-2 receptor alpha chain, on human mast cells is primarily associated with aberrant mast cells in clonal mast cell disorders. However, the regulation of CD25 expression in normal, mature tissue-resident mast cells remains poorly understood. Objective: IL-33 is a key modulator of immune responses, including in lung inflammatory conditions. Because mast cells are
Chronic pancreatitis is a progressive inflammatory disease associated with substantial nutritional and metabolic consequences. Beyond classical malnutrition, patients frequently develop alterations in body composition, particularly sarcopenia, which are increasingly recognised as clinically relevant but remain inconsistently assessed. The reported prevalence of sarcopenia ranges from 20% to 70%, i

Popular Abstract in Swedish Förlossnings- och barnläkare har i många år sökt efter ett instrument för utvärdering av det nyfödda barnets hälsotillstånd. Virginia Apgar introducerade 1953 ett poängsystem som bygger på en subjektiv bedömning av barnets hudfärg, hjärtfrekvens,reflexer/retbarhet, muskeltonus och andning. Koncentrationen i blodet av olika gaser, syror och baser speglar också det nyföddAcid-base status in umbilical cord blood is an objective measure of the fetus’ exposure to and ability to handle hypoxia. The objective of this thesis was to clarify some of the methodological pitfalls in interpreting umbilical cord blood gases and lactate values at birth. Study I pinpoints the methodological confounding in calculating base deficit (BD) with algorithms used in different brands of
Soil mineral weathering is one of the major sources of base cations (BC), which play a dual role in forest ecosystems: they function as plant nutrients and buffer against the acidification of catchment runoff. On a long-term basis, soil weathering rates determine the highest sustainable forest productivity that does not cause acidification. It is believed that the hydrologic residence time plays a
Popular Abstract in Swedish Parkinsons sjukdom beror på att de dopamin-producerande cellerna i hjärnan dör. Detta leder till minskad rörlighet, svårigheter i att påbörja och avsluta en rörelse, balanssvårigheter och darrningar (tremor) hos de drabbade patienterna. Varför dopamincellerna dör är oklart och i nulägat kan man inte bota Parkinsons sjukdom, men man kan lindra symptomen med mediciner. PaParkinson's disease (PD) is a neurodegenerative disorder where the midbrain dopaminergic neurons are lost. Presently there is no cure for PD, and the most common treatment is to replace the lost dopamine pharmacologically by administration of the dopamine precursor L-DOPA. This works very well during the initial treatment period, but unfortunately a majority of the patients develop abnormal involu
Popular Abstract in Swedish Sotpartiklar i atmosfären är en del av klimatfrågan som är i särskilt stort behov av utredning. Dessutom har det visat sig, att samma partiklar orsakar mycket stora hälsoproblem; globalt, på Europeisk nivå, och till och med i förhållandevis förskonade länder som Sverige. Vi vet nu nästintill helt säkert att mänsklig påverkan leder oss in i ett varmare klimat. Vi behöveAerosol particles contribute significantly to the global burden of disease, and remain the main source of uncertainty in assessments of human-induced climate change. The microphysical characterization of particles is necessary to understand the roles they play in the detrimental effects of air pollution on human health, and in the energy budget of our planet. Soot particles are especially relevant
Popular Abstract in Swedish Autoimmuna sjukdomar, såsom typ 1 diabetes, uppstår till följd av en obalans i immunsystemet där immunceller ser kroppens egna vävnader som ett hot och angriper dem. Vid typ 1 diabetes är det de insulin-producerande β-cellerna i bukspottskörteln som förstörs, vilket leder till att man resten av livet får tillföra kroppen insulin genom injektioner. Anledningen till varföAutoimmunity, such as type 1 diabetes (T1D), arises as a result of tolerance breakdown against host tissues, i.e. the β-cells. Central tolerance is established during thymic T cell development and defects in key events during this process could contribute to the pathogenesis of autoimmune diseases. The work presented in this thesis was aiming at unravelling some of those aspects. We have investi

Vattenmolekyler är i ständig slumpmässig rörelse som beror på systemets termisk energi, dvs temperaturen. Diffusionsrörelsen kallas även Brownsk rörelse efter den engelske botanikerns Brown, som upptäckte fenomenet på 1800 talet. Människokroppen består till 70 % av vatten, vilket gör det lämpligt att använda MRT för att studera diffusionsegenskaper i biologisk vävnad och för klinisk diagnostik av Magnetic resonance imaging (MRI) is still a fast growing area of research and is an important part of the clinical tools used for diagnosis of various diseases. The diagnostic values of diffusion imaging are well known especially for ischemic stroke in the acute phase. This work concerns whether the apparent diffusion coefficient (ADC) and the full width at half maximum (FWHM) changes when the ima

Popular Abstract in Swedish Konceptet fjärrvärme inbegriper central värmeproduktion från vilken värme distribueras ut till de enskilda förbrukarna via ett rörsystem. Ett grundläggande krav, med hänsyn till fjärrvärmens konkurrenskraft, är att vinsten som görs i den storskaliga värmeproduktionen, jämfört med lokal värmeproduktion, överstiger kostnaderna för värmedistributionen. DistributionskostnadThe concept of district heating (DH) involves centralised heat production where heat is distributed to consumers via a piping network. It is essential that benefits achieved from concentrated, large-scale production instead of local production in each building exceed the costs associated with heat distribution. Since the distribution cost per delivered kWh increases as the heat density of an area
