Objectives: Carbon dioxide (CO2) angiography for endovascular aortic repair (CO2-EVAR) is used to treat abdominal aortic aneurysms (AAAs), especially in patients with chronic kidney disease or allergy to iodinated contrast medium (ICM). However, some technical issues regarding the visualization of the lowest renal artery (LoRA) and the best quality image through angiographies performed from pigtai

BACKGROUND: Mean diffusivity (MD) and fractional anisotropy (FA) from diffusion MRI (dMRI) have been associated with cell density and tissue anisotropy across tumors, but it is unknown whether these associations persist at the microscopic level.PURPOSE: To quantify the degree to which cell density and anisotropy, as determined from histology, account for the intra-tumor variability of MD and FA in

The thesis concerns glycosyl transfer with use of b-glycosidases, most of them from hyperthermophilic organisms. Both optimisation of the reaction conditions and protein engineering in terms of site-directed mutagenesis were used to improve b-glycosidase-catalysed reactions. The first part of the work deals with conversion of lactose into valuable products such as galacto-oligosaccharides (GOS) an

Popular Abstract in Swedish I denna avhandling studeras ledningsförmågan hos nanometer-stora kvantprickar tillverkade i halvledarmaterial. Halvledare är material vars ledningsförmåga ligger någonstans mellan ledare (metaller) och isolatorer. I halvledare kan ledningsförmågan ändras med elektriska fält, vilket har möjliggjort utvecklandet av halvledartransistorn. Utvecklandet av halvledartransistorThis thesis focuses on electron transport in single and double quantum dots defined in low-dimensional, narrow-band-gap III-V semiconductor materials. Fabrication schemes are presented for defining single and double quantum dots in lateral InGaAs/InP heterostructures, either by a combination of etching and local gating or solely by local top gating. The quantum dots are here electrostatically conf

The European spruce bark beetle is considered as one of the most destructive forest insects to Norway spruce trees in Europe. Climate change may increase the frequency and intensity of bark beetle outbreaks. It is therefore of vital importance to detect the bark beetle outbreaks and take it under control to prevent further damages. Remote sensing techniques may provide a cost-efficient solution to

There is increasing evidence that short-chain fatty acids (SCFA) formed by colonic fermentation of indigestible carbohydrates have beneficial physiological effects. Butyric acid is the main energy substrate for the colonic mucosa and has been implicated as important in the prevention and treatment of diseases of the colonic mucosa, such as distal ulcerative colitis and cancer. Propionic acid, on t

Does perfluorooctane sulfonate (PFOS) and perfluorooctanate (PFOA) exposure disrupt the menstrual cyclicity? The female reproductive system may be sensitive to PFOA exposure, with longer menstrual cycle length at higher exposure. PFOS and PFOA are persistent man-made chemicals. Experimental animal studies suggest they are reproductive toxicants but epidemiological findings are inconsistent. A cros

Strålbehandling är en viktig behandling av cancer och det är avgörande att ge de föreskrivna stråldoserna exakt på rätt plats för att lyckas. Innan en patient behandlas verifieras strålbehandlingen genom kontrollmätningar. Dessa kontrollmätningar utförs med små detektorer som är placerade i ett fantom. Dessa mäter dosen endast i de punkter där de placeras. Stråldosen som ligger mellan dessa punkteBackground & Purpose: Radiation therapy is an essential treatment for cancer patients with the ultimate goal to deliver radiation doses to the tumour with precision while minimizing exposure to surrounding healthy tissues. Treatment verification is crucial to ensure the accuracy of radiation delivery, for instance by measuring the radiation dose distribution. Among various dosimetry techniques

Background: One of the polymer gel dosimeters available today is the N-isopropylamide (NIPAM) polymer gel dosimeter which has a less toxic monomer compared to other polymer gels and the advantage of being able to be manufactured under normal oxygen levels. Polymer gel dosimeters in general are advantageous independent dosimeters to use for verification of new radiation treatment techniques due to

Salinisation is a global issue which leads to desertification and soil degradation and exposure to salt is also known to inhibit microbial activity and plant growth. This study was conducted to determine the influence of salinity on microbial activity of a non- saline soil. By using Salt Induced Community Tolerance (SICT) concept I found that microbial community tolerance to salt can be induced in

Vid en diskussion om nivån på den svenska bolagsskatten är det av stor vikt att avgöra huruvida diskussionen rör den nominella eller den effektiva skattesatsen. Den nominella skattesatsen uppgår till 28 procent och återfinns i 65 kap. 14 § IL. Den effektiva skattesatsen är däremot inte given utan kan i viss utsträckning påverkas, eftersom den bestäms genom att dividera skatt på årets resultat med

Popular Abstract in English Mobile communication systems are now evolving towards the fifth generation (5G). In the near future, we expect an explosive increase in the number of connected devices, such as phones, tablets, wearable accessories, sensors, connected vehicles and so on. We can imagine that much higher data rates than in today's 4G systems are required. Sounds like the future of communiMobile communications are now evolving towards the fifth generation (5G). In the near future, we expect an explosive increase in the number of connected devices, such as phones, tablets, sensors, connected vehicles and so on. Much higher data rates than in today's 4G systems are required. In the 5G visions, better coverage in remote regions is also included, aiming for bringing the current "4 bill

Objectives: Occupational exposure to diesel exhaust is common due the widespread use of dieselpowered combustion engines. Diesel exhaust is chemically complex and consists of thousands of compounds present as gases and particulate matter. Both nitrogen dioxide (NO2) and elemental carbon(EC) have been used as markers for diesel exhaust exposure. Currently EC is regarded as the best surrogate of die

Background: Several aggregate data meta-analyses have provided estimates of the effectiveness of influenza vaccination in community-dwelling elderly people. However, these studies ignored the effects of patient-level confounders such as sex, age, and chronic diseases that could bias effectiveness estimates. We aimed to assess the confounder-adjusted effectiveness of influenza vaccines on laborator

BACKGROUND: Alzheimer's disease is characterized by an abnormal increase of phosphorylated tau (pTau) species in the CSF. It has been suggested that emergence of different pTau forms may parallel disease progression. Therefore, targeting multiple specific pTau forms may allow for a deeper understanding of disease evolution and underlying pathophysiology. Current immunoassays measure pTau epitopes
