Popular Abstract in Swedish Tänk dig ett system som kan bestämma hur olika typer av luftpartiklar skadar oss när dom hamnar i våra lungor. Ett system som dessutom kan skapa luftpartiklar för dessa studier vid behov och med väl uppmätta egenskaper. Denna avhandling handlar om just ett sådant system och experiment som är viktiga för att förstå om och hur det fungerar. Systemet kallas i denna avhandlExposure to nano-sized and nanostructured aerosol particles with tailored properties are likely to increase in society. Occupational exposure to various kinds of nanostructured aerosol particles such as soot and metal aggregates already exists. To understand the adverse human health effects of these particles, there is a need for systems that can Generate a stable output of aerosol particles, Char

Bone mass in adolescents and young adults was studied with regard to its age-related change and its determinants. Methodological aspects of bone mass measurements and their ability to predict future fractures were investigated. Bone mineral content (BMC) and bone mineral density (BMD) were assessed by the Single Photon Absorptiometry (SPA) and Dual Energy X-ray Absorptiometry (DXA) techniques. We

Optical spectroscopy has been used as a supplement to conventional techniques for analyzing and diagnosing cancer in many human organs. Because ocular tumors may be characterized by their different melanin content, we investigated the feasibility of using transscleral visible/near-infrared spectroscopy (Vis/NIRS) to estimate the quantity of melanin in a novel uveal melanoma phantom of ex vivo porc

Context Inpatients with nonvalvular atrial fibrillation, warfarin prevents ischemic stroke, but dose adjustment, coagulation monitoring, and bleeding limit its use. Objective To compare the efficacy of the oral direct thrombin inhibitor ximelagatran with warfarin for prevention of stroke and systemic embolism. Design, Setting, and Participants Double-blind, randomized, multicenter trial (20002001)

Introduction Metabolic dysfunction is one of the hallmarks of sepsis yet little is known about local changes in key organs such as the heart. The aim of this study was to compare myocardial metabolic changes by direct measurements of substrates, such as glucose, lactate and pyruvate, using microdialysis (MD) in in-vivo porcine endotoxemic and hemorrhagic shock. To assess whether these changes were

1. To investigate further the release, localization and identity of a non-nitrergic mediator of smooth muscle relaxation in the female pig urethra, we studied the effects of drugs acting at alpha 2-adrenoceptors or K+ channels, the effects of capsaicin and chemical sympathectomy, and the actions of several transmitter candidates. 2. Electrical field stimulation (EFS; frequencies above 12 Hz) of sp

Popular science summary Are drugs only drugs for human being? An experiment to see if some of the anthropogenic pharmaceuticals are toxic contaminants for the aquatic environment. All kinds of pharmaceuticals have been using widely and the amount has been increased significantly during the last few decades. Concerns about the occurrence of pharmaceuticals releasing into different matrixes of th

Det huvudsakliga syftet med denna uppsats är att undersöka om ett fullgott juridiskt ramverk i syfte att skydda den arktiska regionen redan är etablerat, eller om ytterligare juridiska instrument behöver tillkomma för att så ska vara fallet. Frågan diskuteras med bakgrund av det faktum att den arktiska isen smälter i en hög takt, och att framtiden för regionen sannolikt kommer att se väldigt annorThe main purpose of this thesis is to examine whether or not the legal framework to govern the Arctic can be said to be in place already, or if additional judicial measures need to be taken, given the future that awaits the region as a result of the ongoing rapid ice melt. For many decades, or even centuries, it was the common perception that the Arctic would remain permanently ice-covered, and be

Sammanfattning Instansordningsprincipen är en förvaltningsrättslig princip som huvudsakligen medför att parterna i ett förvaltningsmål är förhindrade att tillföra nytt processmaterial i högre instanser. Principen är, emellertid, inte uttryckligen lagstadgad i Förvaltningsprocesslagen (1971:291), FPL. Istället är det upp till förvaltningsdomstolarna att tolka de uttalande som finns i förarbetena tiSummary The principle of the court hierachy is a principle within administrative law whose intention is to prevent the parties to add new case material in the higher instances. The principle, however, is not explicitly stated in the Administrative Court Procedure Act (1971: 291), FPL. Instead, the administrative courts are given the task to interpret various statements contained in the legislative

When the United Nations was created in 1945, states were the only significant decision-makers. Even with the construction of the human rights regime in the aftermath of the Second World War, states were designated as the only duty-bearers who could violate international human rights law. States alone were held responsible for implementing human rights principles by enforcing treaty-based obligatio

When a child is diagnosed with diabetes, the symptoms may be in its most severe form with ketoacidosis, to mild symptoms of diabetes, detected incidentally. Moderate and severe symptoms of diabetes presentation require infusion therapy and thereby necessitate hospitalisation for the first few days. The initial management is largely a preparation for family members to help them gain the practical u

Atmospheric aerosol samples from a boreal forest (Hyytiala, April 2007), a rural site in Hungary (K-puszta, summer 2008), a polluted rural area in Italy (San Pietro Capofiume, Po Valley, April 2008), a moderately polluted rural site in Germany located on a meadow (Melpitz, May 2008), a natural park in Spain (Montseny, March 2009) and two urban background locations (Zurich, December 2008, and Barce

BACKGROUND: Following the economic crisis in Greece in 2010, the country's ongoing austerity measures include a substantial contraction of health-care expenditure, with reports of subsequent negative health consequences. A comprehensive evaluation of mortality and morbidity is required to understand the current challenges of public health in Greece.METHODS: We used the results of the Global Burden

BACKGROUND: Niemann-Pick disease type C (NP-C) is a rare neurovisceral disease characterised by progressive neurological degeneration, where the rate of neurological disease progression varies depending on age at neurological onset. We report longitudinal data on functional disease progression and safety observations in patients in the international NPC Registry who received continuous treatment w

Background: Dietary risks today constitute the largest proportion of disability-adjusted life years (DALYs) globally and in Sweden. An increasing number of people today consume highly processed foods high in saturated fat, refined sugar and salt and low in dietary fiber, vitamins and minerals. It is important that dietary trends over time are monitored to predict changes in disease risk. Methods:

BACKGROUND: The risk of spinal haematoma in patients receiving epidural catheters is estimated using routine coagulation tests, but guidelines are inconsistent in their recommendations on what to do when results indicate slight hypocoagulation. Postoperative patients are prone to thrombosis, and thromboelastometry has previously shown hypercoagulation in this setting. We aimed to better understand

Importance: Aortic stiffness, as assessed by carotid-femoral pulse wave velocity, is an independent predictor of future events in individuals with hypertension. Recent data suggest a predictive role of estimated pulse wave velocity (ePWV) calculated by previously published equations using age and blood pressure in future events in individuals with hypertension. Objective: To investigate whether eP

The global methane (CH4) budget is becoming an increasingly important component for managing realistic pathways to mitigate climate change. This relevance, due to a shorter atmospheric lifetime and a stronger warming potential than carbon dioxide, is challenged by the still unexplained changes of atmospheric CH4 over the past decade. Emissions and concentrations of CH4 are continuing to increase,

Reliable quantification of the sources and sinks of atmospheric carbon dioxide (CO2), including that of their trends and uncertainties, is essential to monitoring the progress in mitigating anthropogenic emissions under the Kyoto Protocol and the Paris Agreement. This study provides a consolidated synthesis of estimates for all anthropogenic and natural sources and sinks of CO2 for the European Un
