Manganese superoxide dismutases (MnSODs) are enzymes that convert two molecules of the poisonous superoxide radical into molecular oxygen and hydrogen peroxide. During the reaction, the manganese ion cycles between the Mn(2+) and Mn(3+) oxidation states and accomplishes its enzymatic action in two half-cycles (corresponding to the oxidation and reduction of O(2)(*-)). Despite many experimental and
Background: Pro-inflammatory cytokines can affect intracellular lipid metabolism. A variety of effects have been described for different cell types; hepatocyte lipid turnover pathways are inhibited during inflammation, whereas interleukin-1 beta (IL-1 beta) reduces intracellular cholesterol levels in fibroblasts. Levels of the pro-inflammatory cytokines IL-1 beta and tumour necrosis factor-alpha (
Biologically treated wastewater spiked with a mixture of 56 active pharmaceutical ingredients (APIs) was treated with 0-20 mg/L chlorine dioxide (ClO2) solution in laboratory-scale experiments. Wastewater effluents were collected from two wastewater treatment plants in Sweden, one with extended nitrogen removal (low COD) and one without (high COD). About one third of the tested APIs resisted degra
A dynamic mathematical model for simulating the coupled heat and moisture migration through multilayer porous building materials was proposed. Vapor content and temperature were chosen as the principal driving potentials. The discretization of the governing equations was done by the finite difference approach. A new experimental set-up was also developed in this study. The evolution of transient t
Laminar burning velocity of lean hydrogen + air flames at standard conditions is still a debated topic in combustion. The existing burning velocity measurements possess a large spread due to the use of different measurement techniques and data processing approaches. The biggest uncertainty factor in these measurements comes from the necessity to perform extrapolation to the flat flame conditions,
Converting elemental mercury into divalent compound is one of the most important steps for mercury abatement from coal fired flue gas. The oxidation of elemental mercury was investigated in this paper using dielectric barrier discharge (DBD) non-thermal plasma (NTP) technology at room temperature. Effects of different flue gas components like oxygen, moisture, HCl, NO and SO2 were investigated. Re
The Gaia-ESO survey is a large public spectroscopic survey aimed at investigating the origin and formation history of our Galaxy by collecting spectroscopy of representative samples (about 105 Milky Way stars) of all Galactic stellar populations, in the field and in clusters. The survey uses globular clusters as intra-and inter-survey calibrators, deriving stellar atmospheric parameters and abunda
Background: The purpose of the study was to evaluate time trends and effects of co-existing autism spectrum disorders (ASD) on outcome in an ongoing long-term follow-up study of anorexia nervosa (AN). Methods: The Morgan-Russell Outcome Assessment Schedule (MROAS) was used at 6-, 10- and 18-year follow-up of a representative sample of 51 individuals with teenage-onset AN and a matched group of 51
Aim We explored regional variations in the surgical management of patients with Dupuytren's contracture (DC) in 12 European countries using a surgeon survey and patient chart review. Methods Twelve countries participated: Denmark, Finland, Sweden (Nordic region); Czech Republic, Hungary, Poland (East); France, Germany, the Netherlands, UK (West); Italy, Spain (Mediterranean). For the survey, a ran
Probiotics are Live microorganisms that confer a health benefit on the host. The composition of the microflora in the gastrointestinal tract is rather constant in healthy subjects, but is easily disturbed by severe illness and the use of antibiotics. The intestinal barrier that separates the luminal contents, with a very high density of microorganisms, from an almost sterile milieu in the gut wall
Experimental measurements of the adiabatic burning velocity in methane + hydrogen + air flames using the Heat Flux method are presented. The hydrogen content in the fuel was varied from 0 to 20%. Non-stretched flames were stabilized on a perforated plate burner from 20 to 100 kPa. The equivalence ratio was varied from 0.8 to 1.4. Adiabatic burning velocities of CH4 + H-2 + air mixtures were found
X-ray and neutron reflection studies, the latter in conjunction with contrast variation, have been combined to study the interaction of calf thymus DNA (ctDNA) with monolayers of distearoylphosphatidylcholine (DSPC) in the presence of 20 mM Ca2+ ions, at the air–liquid interface as a function of surface pressure (10, 20, 30 and 40 mN m−1). Analysis of the X-ray and neutron reflection data showed t
Objective: to describe the experiences of immigrant parents of an ultrasound examination in the second trimester of pregnancy, highlighting information, communication, thoughts, feelings and well-being. Methods: An exploratory, qualitative study using in-depth interviews with parents separately. Content analysis was used. A total of nine Farsi-speaking couples, in all 18 persons, who now live in S
Tree phenology has been recognized as an important indicator of climate change, and a wide range of budburst models have been developed. The models differ in temperature sensitivity, and the choice of model can therefore influence the result of climate impact assessments. In this study we compared the ability of 15 models to simulate budburst of the main forest tree species in Sweden. Records on t
More and more people around the world are feeling stressed, and the consequences have become a global burden. At the same time, cities are growing both spatially and from within, creating competition for land which sometimes comes at the cost to our access to nature. Natural settings provide people with stress relief, and some of the feelings we perceive in nature are more efficient at this than o
Talade utrymningslarm installeras som en riskreducerande åtgärd i byggnader där det vistas personer som inte kan väntas ha god lokalkännedom. En grundförutsättning för att utrymningslarmet ska uppfylla sin riskreducerande effekt är att det är hörbart, därav är ett talöverföringsindex, STI, på 0,55 rekommenderat. STI är ett mått på taluppfattbarhet som inte tar hänsyn till den subjektiva upplevelseVoice evacuation alarms are installed as a risk mitigation measure in buildings where people reside who cannot be expected to have good local knowledge. Voice evacuation alarms have basic requirements that need to be meet such as auditability, where a speech transmission index, STI, of 0,55 is recommended. STI is a measure of speech intelligibility that does not include the subjective experience o
Projektet Intelligent Survey (IS) utvecklades för att predicera depression och ångest från naturligt språk genom att översätta individers kvalitativa svar från elva öppna frågor till kvantitativa värden som jämförs och prediceras mot skalorna; Patient Health Questionnaire (PHQ-9), Generalized Anxiety Disorder scale (GAD-7), Harmony in Life scale (HILS) och Satisfaction With Life Scale (SWLS). I saThe project Intelligent Survey (IS) was developed to predict depression and anxiety from natural language by translating individuals' qualitative answers from eleven open-ended questions to quantitative values, which are compared and predicted against the scales; Patient Health Questionnaire (PHQ-9), Generalized Anxiety Disorder scale (GAD -7), Harmony in Life scale (HILS) and Satisfaction Wit
