NADPH is a key reductant carrier that maintains internal redox and antioxidant status, and that links biosynthetic, catabolic and signalling pathways. Plants have a mitochondrial external NADPH oxidation pathway, which depends on Ca2+ and pH in vitro, but concentrations of Ca2+ needed are not known. We have determined the K0.5(Ca2+) of the external NADPH dehydrogenase from Solanum tuberosum mitoch

Popular Abstract in Swedish Personer som arbetar med joniserande strålning inom t.ex. sjukvård, kärnteknik och forskning använder så kallade dosimetrar för att registrera hur mycket joniserande strålning (vilken stråldos) personen blivit utsatt för under ett arbetspass eller en arbetsmånad. Den stråldos som en dosimeter mäter ger ett mått på risken för eventuella sena hälsoeffekter i form av en ökIn the event of a radiation accident, it is crucial to make rapid estimates of the absorbed dose received by both emergency workers, so-called first responders, and members of the public. Today, only personnel in rescue teams responding to nuclear emergencies have access to individual dosemeters. To make accurate assessments of the radiological consequences of an emergency situation, methods of re

Both ammonia-oxidizing archaea (AOA) and ammonia-oxidizing bacteria (AOB) play an important role in nitrification in terrestrial environments. Most often AOA outnumber AOB, but the relative contribution of AOA and AOB to nitrification rates remains unclear. The aim of this experiment was to test the hypotheses that high nitrogen availability would favor AOB and result in high gross nitrification r

The aim of this thesis was to elucidate developments in epidemiology, clinical manifestations and complications in Chlamydia trachomatis (C.trachomatis) and Mycoplasma genitalium (M.genitalium) infection. In study I the frequencies of non-gonococcal salpingitis, gonococcal salpingitis and ectopic pregnancy (EP) were observed over a period of 28 years and correlated to the prevalence of Neisseria g

Thrombin generation is a key process that determines the extent of a hemostatic plug or a thrombotic process. The ensuing thrombin burst is crucial for the formation of a stable fibrin clot. During its active life, thrombin exerts a multitude of highly regulated actions on the blood and the vessel wall, among which is the clotting of fibrinogen. The inappropriate generation of thrombin may lead to

Family history of first and second-degree relatives is known to increase the risk for breast cancer. Less data are available on the risks between defined multiple affected close and distant relatives for which the reliability of data may be an issue. Data on affected males are sparse. These questions and the probable genetic models were addressed in this study by means of a nationwide Swedish Fami

The glaciotectonic architecture and structural evolution of a fine-grained end moraine formed by the 1890 glacier surge of Bruarjokull is described from four excavated cross-sections. The end moraine ridge is a morphological expression of a marginal sedimentary wedge formed during the last days of the surge. The actual end-moraine ridge was formed on the last day of the 1890 surge when the glacier

Background: Drug therapy in primary care is a challenge for general practitioners (GPs) and the prescribing decision is influenced by several factors. GPs obtain drug information in different ways, from evidence-based sources, their own or others? experiences, or interactions with opinion makers, patients or colleagues. The need for objective drug information sources instead of drug industry-provi

The topic of cognitive foresight in non-human animals has received considerable attention in the last decade. The main questions concern whether the animals can prepare for upcoming situations which are, to various degrees, contextually or sensorially detached from the situation in which the preparations are made. Studies on great apes have focused on tool-related tasks, e.g., the ability to selec

It is well known that spectroscopic measurements suffer from an interference known as stray light, causing spectral distortion that reduces measurement accuracy. In severe situations, stray light may even obscure the existence of spectral lines. Here a novel general method is presented, named Periodic Shadowing, that enables effective stray light elimination in spectroscopy and experimental result

Strömsrum in SE Sweden is one of the most important areas for threatened insects in northern Europe. This is a review of the red-listed and formerly red-listed species of wood-living beetles collected at Strömsrum with notes of their habitats. In an area of a few hundred hectares over 1000 old hollow oaks and almost as many hollow trees of other deciduous trees occur. From the current red list (Gä

This contribution questions the influential interpretation that strong unions and centralized wage bargaining facilitate wage restraint and that during the postwar period wage restraint was an important cause of strong economic growth performance. This view is contrasted with a power-oriented perspective that sees strong unions as conducive to redistribution from capital to labour, rather than wag

Popular Abstract in Swedish Under sin livstid kommer var tredje svensk i personlig kontakt med någon tumörform. För att effektivare kunna behandla cancer behöver vi bättre förstå de bakomliggande mekanismerna. Varför växer en cancer och hur sker spridningen till andra organ? En cancervävnad består av ett stort antal olika celler som ständigt kommunicerar med varandra. I en frisk vävnad finns regleCell behavior such as migration and proliferation, especially during cancer development, are balanced by the surrounding environment. Complex polysaccharides called glycosaminoglycans (GAGs) are part of this environment and they are known to modulate tumor development. One of these GAGs, dermatan/chondroitin sulfate (CS/DS), is attached to proteins either bound to the cell surface or secreted in t
