Summary: Reduction of the cerebral perfusion pressure caused by vessel occlusion or stenosis is a cause of neurological symptoms and border-zone infarctions. The aim of this article is to describe perfusion patterns in hemodynamic stroke, to give a practical approach for the assessment of colour encoded CT- and MR-perfusion maps and to demonstrate the clinical use of comprehensive imaging in the w
Permutational Grammar, PG, is a grammar inspired by the Free Word Order grammar, FOG, presented in Vladimir Pericliev & Alexander Grigorov 1992. Some languages, notably Latin, are said to have free word order, see e.g. Siewierska 1988. The name Permutational Grammar is derived from the use of permutations in order to generate order variation. The general problem to be solved by FOG and PG is t
The aim of this study was to assess the long-term effects of a high-energy dense diet, supplemented with Lactobacillus plantarum (Lp) or Escherichia coli (Ec) on weight gain, fattening and the gut microbiota in rats. Since the mother’s dietary habits can influence offspring physiology, the dietary regimes started with the dams at pregnancy and through lactation, and continued with the offspring fo
Salt-inducible kinase (SIK) 3 is a virtually unstudied, ubiquitously expressed serine/threonine kinase, belonging to the AMP-activated protein kinase (AMPK)-related family of kinases, all of which are regulated by LKB1 phosphorylation of a threonine residue in their activation (T)-loops. Findings in adrenal cells have revealed a role for cAMP in the regulation of SIK1, and recent findings suggest
CONTEXT: The prevalence of obesity among adolescents has increased and we lack effective treatments. OBJECTIVE: To determine if gastric bypass is safe and effective for an unselected cohort of adolescents with morbid obesity in specialized health care. DESIGN, SETTING AND PATIENTS: Intervention study for 81 adolescents (13-18 years) with a body mass index (BMI) range 36-69 kg m(-2) undergoing lapa
Popular Abstract in Swedish Ovan jord & under ytan Sandstäpp är en hotad växtmiljö eftersom arealen av sandstäpp minskat avsevärt sedan Linnés tid (1700-talet). Vi ställde oss frågan varför den har minskat. För att kunna besvara den måste vi förstå vad växtarterna behöver och förstå hur kemin i marken fungerar. Dessutom vill vi lära oss hur markens organismer påverkas av minskningen av sandstSandy, calcareous grasslands are species rich temperate semi-natural grasslands. The species composition in 136 plots was analysed in relation to soil chemistry parameters; extractable P and N, soil pH and lime content. We found that that acidification and decalcification decrease species diversity and the number of red-listed species in these sandy grasslands. The microbial community was investig

Wetlands are one of the most precious ecosystems in the world. They are important be-cause of their high biological diversity and unique properties, such as water purification and carbon sequestration. Yet, wetlands are also one of the most endangered ecosystems due to land draining. In Sweden, wetlands have been drained för centuries due to the lack of arable land. The draining can have been acco
The number of CT examinations giving a relatively high patient exposure is increasing. It is therefore important to optimize the imaging conditions at these investigations. Many steps have been taken to reduce the radiation doses in CT examinations. Currently much work is related to iterative image reconstruction methods as alternative to the filtered back projection method. The aim of this work w

Popular Abstract in Swedish Alla levande organismer har DNA, och eftersom DNA är livsnödvändigt måste det repareras om det blir skadat. Ultraviolett (UV) strålning från solen är en av de vanligaste orsakerna till att DNA skadas. De flesta skador på DNA som orsakas av UV-strålning utgörs av cyklobutan-pyrimidindimerer (CPD) eller (6-4)-fotoprodukter. Dessa skador består av två intilliggande baser sAll living organisms have DNA and since DNA is essential to life it must be repaired when damaged. UV radiation is one of the major DNA damaging agents, which photosynthetic organisms cannot avoid. The major UV-induced DNA lesions are cyclobutane pyrimidine dimers (CPDs) and (6-4) photoproducts (6-4PPs) and the main repair pathways of theses lesions involve photolyases and various excision repair
Only 15% to 30% of product development projects require the development of new product concepts. This means that the majority of design projects are carried out within the embodiment design and detail design phases. However, the majority of the research studies on the mechanical engineering design process, or design process for short, have been focusing on the conceptual design phase. The embodime
Popular Abstract in Swedish Prostatacancer är idag den vanligaste sjukdomen hos män, och är den cancer form som leder till flest dödsfall bland män i Sverige (av de män som får diagnosen avlider 35% på grund av sjukdomen). Det har visats att risken att utveckla prostatacancer påverkas av ålder, etnicitet och diet (bla asiatisk mat och tomater verkar ha skyddande effekt), men också av genetiska fakProstate-specific antigen (PSA) is a worldwide used tool for the diagnosis and monitoring of prostate cancer. It is a serine protease and belongs to the family of glandular kallikreins. Humans have three classical glandular kallikreins, but it has been reported that rodents have many more. Lately, the family has been expanded to contain 12 new genes, KLK4–KLK15, that are situated at the same locus
Popular Abstract in Swedish Denna avhandling handlar om hjälpande och framförallt om givande till välgörenhet. De två centrala frågorna som ställs handlar om när vi hjälper (i vilka situationer hjälper vi mer eller mindre?) och om varför vi hjälper i dessa situationer (vilka sorters känslor och tankar gör oss mer motiverade att hjälpa?) Hjälpeffekter: När hjälper vi? Frågan om när vi hjälper hanThe overarching purpose of this thesis was to investigate if different helping effects can be specifically linked to different psychological mechanisms. Helping effects (i.e. the when of helping) refer to situational differences that can increase or decrease the probability of helping. The three helping effects in focus in this thesis, were (1) the identifiable victim effect (the tendency to be
In this paper we show that several metals, elements and energy resources are about to run into scarcity within the next decades, and most elements within some centuries. A new global systems model was assembled to analyse this scarcity as a continuation of the model used in the Limits-to-Growth World3 model. We show that this scarcity will lead to “peak wealth”, “peak population”, “peak costs”, “p
Numerical simulations are performed for multiphase jets in crossflow. The flow solver uses an Eulerian/Lagrangian approach. Turbulence in the gas phase is modeled in the framework of large eddy simulation. The dispersed phase is handled using Lagrangian particle tracking. The model assumptions of solvers for Lagrangian particle tracking are critically assessed for typical flow conditions of spray
Popular Abstract in Swedish Ett högt fiberintag från grönsaker, frukt och sädesslag som havre och korn minskar risken för hjärt- och kärlsjukdomar och typ 2 diabetes. Havre och korn har en hög halt av lösliga kostfiber, så kallade beta-glukaner (beta-glukaner) och studier har visat att beta-glukaner har intressanta hälsoeffekter. Ett dagligt intag av beta-glukaner från havre eller korn kan sänka kSince soluble fibre in the form of the cereal beta-glucans found in oats and barley has been shown to have a positive effect on lipid and glucose metabolism, people at risk of developing cardiovascular diseases or diabetes might benefit from that a variety of palatable food products containing beta-glucans being available to them. The aim of the papers presented in the thesis was to evaluate the m
Bacteria and fungi are the main agents in decomposition of soil organic matter. Their activity is determined by the availability and quality of substrate, especially its content of carbon, but also nitrogen and phosphorus. Other environmental factors, which affect the activity of the microbial community in soil, are temperature, moisture and pH. In this thesis the focus was on how temperature and
Salvage hypospadias surgery is performed after failed primary reconstruction. Several treatment strategies have been suggested, all with pros and cons. The aim of this study was to evaluate our treatment algorithm for primary hypospadias repair applied to secondary cases in which a salvage procedure is indicated and, most importantly, local tissue is present. The algorithm was applied to 36 consec
