Popular Abstract in Swedish Ultraljud brukar oftast förknippas med diagnostiska metoder såsom fosterdiagnostik men kan även användas för terapeutisk behandling. Terapeutiskt ultraljud bygger på att ljudet absorberas i vävnaden och därigenom ger upphov till en ökad temperatur. Temperaturökningen är beroende av ultraljudets intensitet samt ultraljudsabsorptionen i den aktuella vävnaden. Genom att foThe purpose of this study was to study and try to optimise high intensity focused ultrasound treatment of the intervertebral disc. We demonstrated that it was possible to heat intervertebral discs with HIFU delivered by 50 or 5 mm diameter ultrasound transducers. Finite element studies indicated that it would be possible to heat the disc to a temperature of 65ºC or above through an extradiscal m

Since the fusions are intraspecies, and in many cases involve highly aneuploid lines, it is not possible to perform de- tailed cytogenetic analyses. However, comparisons of total chromosome counts of hybrid clones with those of the parental cell lines indicate varying de- grees of chromosome loss in the hybrids. The median chromosome number in the hybrids from the GM 639 x T98G and GM 639 x GM 639

Popular Abstract in Swedish Därför får man sockersjuka (Felix Mulder, 6 år): ”Det är inte bra att äta för mycket socker. Socker är vasst och skär sönder blodkropparna. Då kan man inte göra insulin och man blir sjuk.” Islet amyloid polypeptide (förkortat: IAPP) är ett medelstort äggviteämne - peptid - som upptäcktes 1986 av Per Westermark i Uppsala. Denna upptäckt har en intressant bakgrund. Det hIslet amyloid polypeptide (IAPP; also named ”amylin”) is a member of the calcitonin superfamily of peptides, displaying the closest structural relationship to the neuropeptide calcitonin gene-related peptide (CGRP). It is expressed in islet beta-cells and forms islet amyloid in type 2 diabetic patients. IAPP may restrain release and peripheral actions of insulin. Thus, IAPP has been implicated in

Closing implementation gaps through sustainable action nets This project deals with the principle formulated by the Swedish Environmental Protection Agency that sustainable waste policy should be oriented toward waste prevention and not only waste management. National authorities can steer through decisions and legislation, and introduce incitements and control mechanisms. But practical responsibi

In Paper I, 4703 subjects from the Malmö Cost Cancer cohort, with a mean follow-up of 16.5 years, were evaluated for future risk of ischemic stroke in relation to levels of s-LOX1. An increased risk was found for higher level of sLOX-1 OR 1.75 (1.28-2.39), p<0.001, increasing in presence of carotid plaque OR 2.42 (1.71-3.44), p<0.001. Endothelial cells were exposed to oxLDL, resulting in release o

Popular Abstract in Swedish Energianvändningen i världen måste minska drastiskt inom en snar framtid för att därmed minska utsläppen av växthusgaser och bromsa klimatförändringarna. Energi och handlande med energikällor har även blivit nationella säkerhetsfrågor. Inom Europeiska Unionen används ungefär 40% av den totala energianvändningen i byggnader, vilket innebär ungefär 36% av det totala koldiThe use of energy is a major global issue both according to climate changes but also in the aspect of national safety tied to the trade with energy sources. Of the total energy use in the member states of the European Union, about 40% is used in residential and commercial buildings. Passive houses are one way to reduce the energy use in buildings and at the same time keep a good indoor comfort. Th

Wood-based light-weight I-beams are today widely used in the construction industry. An important feature of these beams is that the user can make holes in the web where needed. Today there is no general method used to calculate the reduced strength of these beams with a hole in the web. The calculation methods vary between the manufacturers and are commonly based on empirical results. The aim of t

The focus in this thesis has been active power from small scale solar production and what possible impacts an increased proportion of small scale production can have, in a larger context, during short circuit (SC) faults in the grid. The main research question prompting this work was whether active power from small scale solar pro- duction can help support voltages during SC faults, and meet LVRT-

This study aimed to test and validate a dual-time-window (DTW) protocol for 6-(fluoro-18F)-3-(1H-pyrrolo[2,3-c]pyridin-1-yl)isoquinolin-5-amine ([18F]MK6240) dynamic PET imaging in experimental datasets acquired in human subjects. Methods: DTW protocols were tested and validated in datasets previously collected in 25 participants: 13 were cognitively normal, 10 had mild cognitive impairment, and 2

Popular Abstract in Swedish Knäartros är en mycket vanlig sjukdom som leder till successiv nedbrytning och förlust av brosket i leden, en process som oftast tar 10-20 år. Detta orsakar svår smärta och stelhet och i dag saknas botande behandling mot artros. Det är dock rimligt att anta att en behandling har bättre förutsättningar att lyckas ju tidigare den sätts in. Man vet att det tidigt under sjuDelayed gadolinium-enhanced MRI of cartilage (dGEMRIC) is a new technique to study cartilage glycosaminoglycan (GAG) content. The negatively charged contrast agent Gd-DTPA2-, injected intravenously, distributes in the cartilage inversely to the likewise negatively charged GAG. The GAG concentration is reflected by the MRI parameter T1 and the Gd-DTPA2- concentration by the MRI parameter R1 (R1=1/T

Nitric oxide (NO)/cyclic GMP (cGMP)-mediated mechanisms have a pivotal function in reducing the tone of the penile smooth musculature during normal erectile responses. The cyclic AMP ( cAMP) signaling pathway is also involved in the adjustment of smooth muscle contractility, and suggestions for interactions between cGMP- and cAMP-mediated mechanisms have been presented. Using activators of the cGM

Background: De novo lymphatic vessel formation has recently been observed in lungs of patients with moderate chronic obstructive pulmonary disease (COPD). However, the distribution of lymphatic vessel changes among the anatomical compartments of diseased lungs is unknown. Furthermore, information regarding the nature of lymphatic vessel alterations across different stages of COPD is missing. This

Popular Abstract in Swedish En cancerpatient kommer till sjukhuset för att genomgå en strålbehandlig. Sjukhusets personal tar bilder av patienten och identifierar tumörens placering och utbredning. Bilderna läggs in i ett datorprogram, som i sin tur simulerar en strålbehandling. Strålningsapparaten, dvs. linjäracceleratorn, har flera justerbara parametrar; strålfältets storlek, vinkeln på den infa

Hematopoiesis is a lifelong, dynamic process in which a small number of pluripotent hematopoietic stem cells (HSC) residing in the bone marrow (BM) give rise to billions of mature blood cells of both myeloid and lymphoid origin each day. This enormous capacity of HSC has been utilized in BM transplantations for 4 decades and is also very important for future gene therapy. Understanding what molecu

Breast cancer is the most common type of cancer worldwide with an estimate of 2.3 million new cases in 2020, and the number one cause of cancer-related deaths in women. While survival rates are high in many high-income countries, with a five year relative survival rate of 85% and more, the respective survival rates are poor in many middle- and low-income countries, with rates as low as 12% in Kyad

Achilles tendon rupture is becoming more prevalent with an increasing population of middle aged people participating in recreational sports. A torn Achilles tendon will likely not regain its original function, and it is unknown what treatment options are optimal. The Achilles tendon structure and how the tendon heals after a rupture varies between humans. A potentially useful tool in understanding

Background: Experimental analyses of the 3D strain field evolution during loading allows for better understanding of deformation and failure mechanisms at the meso- and microscale in different materials. In order to understand the auxetic behaviour and delamination process in paperboard materials during tensile deformation, it is essential to study the out-of-plane component of the strain tensor t
