BackgroundIt remains unclear as to why some individuals at low risk of cardiovascular disease (CVD) develop severe coronary atherosclerosis, while those at high CVD risk may remain free from coronary atherosclerosis.PurposeUsing Coronary Computed Tomography Angiography (CCTA), we aimed to identify factors associated with absence and severe coronary atherosclerosis in subjects from the general popu

Fat-soluble vitamin D is an essential bioactive compound important for human health. Insufficient vitamin D levels can result not only in bone disease but also in other disorders, such as cancer, metabolic disorders, and diseases related to poor immune function. The current methods commonly used for vitamin D analysis are often applied to determine the levels of the most abundant metabolite in pla

BACKGROUND: Acute allergic reactions (AARs) occur shortly after exposure to an allergen, and the severity is on a continuum. Systemic corticosteroids (CS) are mainstay treatment of moderate to severe AARs, whereas those at risk of the most severe AARs (ie, anaphylaxis) are also recommended prescription of epinephrine autoinjectors. There is limited research on the impact of AARs not fulfilling the

Att förutsäga framtiden – modellering som ett verktyg för att förutsäga vattenkvantitet och vattenkvalitet Inom 100 år så kommer klimatet förändrats avsevärt om utsläpp av växthusgaser fortsätter i samma takt som idag. Detta kommer påverka temperatur, nederbörd vilka i sin tur påverkar flödet av vatten i Sverige. Ett avrinningsområde består av olika jordtyper, vegetation och topografi, vilka allClimate change will alter the hydrological cycle in the 21st century with implications for the water balance and water quality. As characteristics of the landscape may vary significantly between nearby locations, hydrological models need to be able to delineate responses attributed to specific landscape characteristics, to estimate their responses to altered climatic drivers. Small streams are the

Background The two main functional goals of postural control are postural stability (balance) and postural orientation. Postural orientation is the ability to maintain alignment between body segments and the environment during a static or dynamic activity. Nae et al. have evaluated the measurement properties of a clinical test battery for assessing postural orientation errors (POEs) in patients wi

Bakgrund: Obesitas och psykisk ohälsa tillhör de största globala hälsoutmaningarna i modern tid och har under de senaste decennierna varit ett växande problem. Människor har fått en mer stillasittande livsstil och större tillgång på kaloririk föda. Faktorerna som påverkar prevalensen är många men att det behöver ske en förändring är säkert. Syfte och frågeställningar: Syftet var att kartlägga BMI,

This thesis explores the implementation and acceptability of blanket (population-wide coverage of active case finding and prevention) Post-Exposure Prophylaxis (PEP) as a preventive measure for leprosy transmission in the Achham district of Sudurpaschim (Far-west) Province in Nepal. Leprosy remains a significant public health concern in Nepal, with persistent challenges in prevention and control e

Människans roll inom IS kan ofta falla till glömska inom organisationer som besitter en hög teknisk medvetenhet. Då utvecklingen av tekniska lösningar sker i explosionsartad takt blir möjligheten för användaren att hänga med mindre för varje ny funktion. Säkerhetsmedveten-het är därmed en fråga som bör diskuteras och göras mer aktuell inom organisationer idag då litteratur påvisar att det inte fin

Katalysatorer påskyndar en reaktion utan att själva förbrukas; denna mening känner nog många igen från sin skoltid. Andra har hört talas om katalysatorer som något de "har i bilen". Mycket riktigt är det främst i bilar där vi i våra vardagliga liv stöter på katalysatorer. Här används de för att omvandla de mycket giftiga gaserna kolmonoxid och kväveoxid till för människorna ofarligt kvävIn order to fully understand the underlying processes of catalysis, it is vital to combine measurements of the catalyst surface, where the reaction occurs, with measurements of the gas concentration close to the catalyst. We have developed a convenient setup, which uses a single laser system to visualise the gas surrounding a working catalyst in situ at realistic operating conditions. Planar Lase

This master thesis project was performed in collaboration with Johnson Matthey. Johnson Matthey is a worldwide company working with sustainable technologies. The site in Perstorp, where this work was performed, focus on formaldehyde production. In order to continuously improve chemical processes, simulation and modeling are advantageous tools. They can give a better understanding of the processes

Background: The aim of this study was to examine in elderly men a relationship between depressive symptoms, peripheral vascular disease and cerebral blood flow (CBF). Methods: Population-based cohort study started with an examination of 809 men at age 55, followed by the first (age 68ys) and second follow up (age 82ys). 128 survivors were examined at age 82 with Tc-99m-HMPAO-SPECT to estimate CBF,

Intermittent Parathyroid Hormone (PTH)((1-34)) has an established place in osteoporosis treatment, but also shows promising results in models of bone repair. Previous studies have been dominated by closed fracture models, where union is certain. One of the major clinical needs for anabolic therapies is the treatment of open and high energy fractures at risk of non-union. In the present study we th

Popular Abstract in Swedish Under det senaste decenniet har risker med och alternativ till allogent blod (blod från främmande givare) debatterats mycket pga. risken för smitta, allergiska reaktioner, samt starka indicier som talar för att blod från främmande givare kan påverka immunförsvaret hos mottagaren. Därför vill man gärna begränsa mängden tillfört givarblod under kirurgiska ingrepp på barn,In children, it is often desirable to minimize allogenic blood transfusion, and this thesis explores the physiology of an alternative method of managing perioperative blood loss: hemodilution with Ringer´s dextran. Methods Clinical studies: Arterial pressure, superior caval venous oxygen saturation (ScvO2) and blood lactate concentration (L) were studied during bone marrow harvesting (BMH) on 23

We assessed hepatocellular carcinoma (HCC) risk associated with smoking and alcohol consumption and their interactions, using both questionnaire data and objective serum biomarkers. Information on smoking and alcohol consumption was collected at baseline from 450,112 participants of the EPIC cohort, among whom 255 developed HCC after a median follow-up of 14 years. In a nested case–control subset

This paper examines if competition between internet service providers using city networks leads to lower prices. The research tests the theory of the circular city that in which the price depends on the marginal cost as well as the number of competitors in the market. Based on this theory the cost of a 100 Mbits connection should move towards marginal cost if there are more internet service provid

Aircraft observations of precipitating clouds with cloud top temperatures higher than -38°C have revealed that Secondary Ice Production (SIP) is responsible for presence of majority of ice particles. One such SIP mechanism is fragmentation via collisions between ice particles. The central theme of this study is to understand the dependencies of this SIP mechanism and improve its existing numerical

Titel: Validering av en handledsburen aktivitetsmätare och en självskattningskala för beräkning av VO2max. Bakgrund: Fysisk aktivitet och god aerob kapacitet är kopplat till god hälsa och lägre risk för livsstilsrelaterade sjukdomar. I dagsläget anses maximalt arbetsprov med ergospirometri och gasanalys för bestämning av VO2max (VO2max-test) vara det mest exakta sättet att mäta aerob kapacitet. Su

Forests form the backbone of the European terrestrial carbon sink (State Forest Service & Ministry of Environment, 2018). As the European Union (EU) strives to become climate neutral by 2050, forests are accounted for the natural carbon absorption mechanism (European Commission, n.d.). Currently, the European net land carbon sink is decreasing largely due to forest ageing (Pilli et al., 2022),

The transition from animal-based to plant-based proteins is rapidly increasing because of different concerns about meat consumption, some being the nutritional and environmental effects of meat consumption. During this transition, there needs to be a holistic approach to assessing plant-based food. This master thesis is focused on investigating the nutritional and environmental impact of three pla

Context: Secondary hypogonadism is common in aging men; its natural history and predisposing factors are unclear. Objectives: The objectives were 1) to identify factors that predispose eugonadal men (T >= 10.5 nmol/L) to develop biochemical secondary hypogonadism (T < 10.5 nmol/L; LH <= 9.4 U/L) and secondary hypogonadal men to recover to eugonadism; and 2) to characterize clinical features associ
