Popular Abstract in Swedish Vad är analytisk kemi? Den grundläggande frågeställningen för en analytisk kemist är att finna vad för slags ämnen det finns i ett prov och hur mycket det finns av varje ämne. Detta är inte på långa vägar någon lätt uppgift. Det innebär i många fall att alla ämnen måste separeras från varandra för att sedan kunna identifieras. Som tur är så är de flesta ämnen olika varaThis thesis deals with the combination of electrochromatography and molecular imprinting technology. Electrochromatography is characterised by high separation efficiency, simple instrumentation, and minute consumption of sample. As a novel approach to obtain unique selectivity in capillary electrochromatographic systems molecularly imprinted matrices were used. Molecular imprinting technology repr

The composition of the colonic microflora is essential for the health of the human host. To be able to survive, the microflora is dependent of a continuous supply of substrate. In this respect dietary fibre and other indigestible carbohydrates, of which the consumption in affluent societies is generally low, are of great importance. Numerous of studies have demonstrated beneficial effects of dieta

Popular Abstract in Swedish Den medicinska termen sepsis, "blodförgiftning" orsakas av bakterier i blodet. Symptombilden kan variera från tämligen lindriga förlopp till septisk shock, som har en hög dödlighet. Vid sepsis och septisk shock aktiveras olika kroppsegna system såsom koagulations- och komplementsystemet. Många mekanismer medieras av så kallade cytokiner. Dessa budbärarmolekyler byggs upPurified bacterial cell wall components peptidoglycan and teichoic acid were isolated from staphylococcal species S. aureus and/or S. epidermidis and tested for their ability to induce cytokine release from plastic-adherent human monocytes. Both cell wall components dose-dependently induced TNF-alpha, interleukin-1beta, and interleukin-6 release, peptidoglycan being more potent than teichoic acid.

Background: Vascular-targeted photodynamic therapy, a novel tissue-preserving treatment for low-risk prostate cancer, has shown favourable safety and efficacy results in single-arm phase 1 and 2 studies. We compared this treatment with the standard of care, active surveillance, in men with low-risk prostate cancer in a phase 3 trial. Methods: This randomised controlled trial was done in 47 Europea

En delägare som innehar kvalificerade andelar i ett fåmansföretag omfattas av de s.k. 3:12-reglerna som innebär att utdelning och kapitalvinst till viss del ska beskattas i inkomstslaget tjänst i stället för i inkomstslaget kapital. Om delägaren ska överlåta företaget kan han eller hon inom lagens gränser vidta en rad åtgärder för minska och senarelägga skatten som ska betalas för kapitalvinsten. A shareholder who holds qualified shares in a closely held company is subject to a special set of tax rules named the 3:12 rules. These rules lead to shareholders’ dividends and capital gains to some degree being taxed as labor income instead of capital income. If the shareholder should transfer the company, it is possible – within the boundaries of the law – to make some arrangements to reduce an

Radiotherapy (RT) after mastectomy has been part of the treatment for early breast cancer since the 1940s. The treatment reduces the risk of loco-regional recurrences, but implies risk of late side effects that can begin decades after RT. Aims of the thesis were: - To analyse the long term effects of postmastectomy radiotherapy and systemic treatment for 1100 stage II breast cancer patients in t

The Iron Closet has always been deep, and although never leading to Narnia it has on occasions had the potential to be a one-way ticket to a forced labour camp. After the decline of the Soviet Union, however, the Western world rejoiced; the second parenthesis had been set out and we now lived in the main narrative again where everything ought to make sense. Countries in the post-Soviet space would

Purpose: In 2019 Varian EthosTM linear accelerator (Varian Medical Systems, CA, USA) with integrated artificial intelligence (AI) was installed at Herlev Hospital, Copenhagen, Denmark, enabling online adaptive radiotherapy (oART) e.g for bladder cancer patients with a large margin reduction. The AI utilizes so called influencers for initial delineation of the targets and organs at risks (OAR) usin

Popular science summary: Healing: what we can learn from white mice Stem cells are a cell type responsible for building the body. They are the ancestor cells from which all the cells making up the body’s tissues are created. Stem cells play an important role in maintaining the body in shape by repairing damages as they occur during life. We believe that if we had a better understanding of how t

Abstract Toxic cyanobacterial blooms can form in both freshwater and marine environments, which could threaten the health of human beings and animals. The genera that are known for causing the scums in freshwater are Anabaena, Microcystis, Cylindrospermopsis and Planktothrix. In order to control lake water quality and minimize the potential health risk associated with the cyanobacterial blooms, th

Abstract Agricultural intensification is causing a worldwide loss in biodiversity, and organic farming has been proposed as a valid method for preserving it. Studies have shown that organic farming increases species abundances, however the taxonomic breadth of communities may be an additional important biodiversity measure which is not affected by study intensity or sample size. The aim of this s

In Sweden, the tramway was introduced in the late 19th century as horse tramways. Entrepreneurs around the country saw advantages of the new mean of transport which, due to low frictional resistance could transport a large amount of passengers with low traction force. In the beginning of the 20th century the horses were replaced by electric motors and the tramway spread to more cities. The entry o

Rising organic matter concentrations in surface waters in many Nordic countries require current drinking water treatment processes to be adapted. Accordingly, the use of a novel nanofiltration (NF) membrane was studied during a nine month period in pilot scale at a large drinking water treatment plant in Stockholm, Sweden. A chemically resistant hollow-fibre NF membrane was fed with full scale pro

The eminent dilemma around the relationship between the increasing world population, the need of new fuel sources and environment issues has raised great awareness in the last decades. The European Parliament has set common goals such as the reduction of the greenhouse gases by 20 % by the year of 2020, followed by the requirement of at least 10 % of the fuel has to be biofuel.

Popular Abstract in Swedish Stroke hos unga vuxna råttor och möss utlöser neurogenes i den skadade regionen striatum samt i den intakta hippocampus, men eftersom stroke framförallt drabbar äldre individer, är det av största vikt att utröna åldrandets effekt på hjärnans mekanismer för återhämtning. Gamla och unga vuxna råttor inducerades med stroke genom transient ocklusion av mellersta hjärnartäreStroke in young adult rodents triggers neurogenesis in the damaged striatum and intact hippocampus. as stroke happens frequently in aged individuals it is of great importance to know whether aging affects brain recovery mechanisms. Aged and young adult rats were subjected to stroke by transient occlusion of the middle cerebral artery and proliferating cells were labeled by intraperitoneal administ

Silk fibers offer untapped internal structures to template the formation of nano-objects and active coatings. So far, access to all or part of the internal and organized structures has been a significant challenge. The aim of the thesis is, therefore, to identify and exploit silk templating ability to create value-added multifunctional hybrid materials with enhanced conductive and catalytic proper

Ongoing consumption of fossil-based fuels generates a massive amount of greenhouse gases. This may lead to global warming that is currently threatening human society and wild animal habitats. Hydrogen is an energy carrier with the highest energy content per weight compared to other all fuels and no carbon dioxide is released when combusted. Thermophilic bacteria belonging to the genus of Caldicell

Background: Haematopoietic stem cells expressing the CD34 surface marker have been posited as a niche for Mycobacterium tuberculosis complex bacilli during latent tuberculosis infection. Our aim was to determine whether M tuberculosis complex DNA is detectable in CD34-positive peripheral blood mononuclear cells (PBMCs) isolated from asymptomatic adults living in a setting with a high tuberculosis

I denna rapport redovisas populationstrender för 178 svenska fågelarter för åren 1975–2013. Fåglarna har räknats på vintern och på sommaren enligt strikt standardiserade metoder. Sommar- respektive vinterpunktrutter har räknats sedan 1975, i huvudsak i södra Sverige. Standardrutterna räknas också på sommaren (sedan 1996) men täcker hela Sverige. Vintern 2012/2013 räknades 130 000 fåglar av 128 artWe present the results of the Swedish Bird Survey, run by the Department of Biology, Lund University, as a part of the National Monitoring Programme of the Swedish Environmental Protection Agency.
