Popular Abstract in Swedish Tjocktarmcancer är en av de vanligaste cancerformerna i västvärlden. I Sverige drabbas årligen ca 5000 människor. Ungefär 10% av fallen går att härleda till ärftliga faktorer medan den övervägande delen orsakas av miljöfaktorer. Kända riskfaktorer är fysisk inaktivitet, fetma och rökning. Risken för cancer påverkas dock mest av den kost vi äter. Allmänt kan sägas att enSphingomyelin (SM) is present both in eucaryotic cells and the diet. Sphingomyelinase (SMase) hydrolyses SM and generates ceramide that has been implicated in the regulation of cell growth, differentiation and apoptosis. Previously a SMase with alkaline pH optimum was identified in the intestinal tract. The thesis studied the distribution pattern, the species difference and the clinical implicatio

Popular Abstract in Swedish Det är välkänt att utflödesobstruktion kan leda till förstoring av blåsan med åtföljande minskning av kontraktionskraften, något som kan påvisas både in vivo och in vitro. I arbete I undersöktes därför om det fanns regionala skillnader i blåsmuskelfunktion hos kaniner med experimentell utflödesobstruktion. Efter 2 veckors obstruktion utfördes cystometri och därefter undThe consequences of bladder outlet obstruction (BOO) with respect to detrusor hypertrophy, structural and functional changes, and obstruction-induced detrusor overactivity were investigated in vivo and in vitro utilizing various animal models. Possible pathophysiological pathways and therapeutic approaches were tested by drug treatment and the use of knockout models. Furthermore the role of estrog

Available safe egress time is an important criterion to determine occupant safety in performance-based fire protection design of buildings. There are many factors affecting the calculation of available safe egress time, such as heat release rate, smoke toxicity and the geometry of the building. Heat release rate is the most critical factor. Due to the variation of fuel layout, initial ignition loc

Popular Abstract in Swedish Information om vår omvärld förmedlas med hjälp av elektriska och kemiska signaler i kroppens olika nervbanor till hjärnan där vi tolkar signalerna. Dessa s.k. sensoriska signaler förmedlar information om så skilda saker som hur maten smakar till hur varmt det är, hur ett föremål ser ut, känns osv, till smärtinformation som hjälper oss att undvika farliga situationer. I Neuropeptide expression in the nervous system is abundant and plastic, and an altered expression after injury is an example of a functional response, helping the neuron to cope with adverse changes, and involves effects on differentiation, synthesis, repair/regeneration, survival, and modulation of signal transmission. I have investigated the distribution/expression of the neuropeptides, orphanin

Smad5 is known to transduce intracellular signals from bone morphogenetic proteins (BMPs), which belong to the transforming growth factor-beta (TGF-beta) superfamily and are involved in the regulation of hematopoiesis. Recent findings suggest that BMP4 stimulates proliferation of human primitive hematopoietic progenitors in vitro, while early progenitors from mice deficient in Smad5 display increa

Purpose: The purpose is to investigate which of the selected models that forecasts the out-of-sample data most accurate and whether the model based estimators make better forecasts than the implied volatility. Methodology: Trough in-sample data from a Swedish stock index return series and a exchange rate return series, different forecasting models are evaluated to see which one that predicts the

Aims: The Atrophodermas include a large group of disorders appearing as localized or widespread depressed skin areas and characterized by underlying dermal atrophy. The present study aims to report a peculiar form of previously unreported focal dermal atrophy. Methods: We studied over a period of 5 years a boy who manifested, since birth, multiple hypopigmented cutaneous atrophic lesions of the at

Kvaliteten på kliniska bilder har stor betydelse för korrekt medicinsk diagnostik. I konventionella morfologiska MR-bilder är signalen normalt relativt hög i förhållande till bruset. Vissa nya MR-metoder för s.k. funktionsdiagnostik bygger emellertid på en avsiktlig degradering av signalen för att vissa kvantitativa parametrar skall kunna beräknas. I sådana studier kan följaktligen signal-till-bruNoise is a well-known problem in many imaging modalities. In magnitude magnetic resonance images, obtained by quadrature detection, the associated Rician distribution of noise constitutes a further complication. This type of noise is especially problematic at low signal-to-noise ratio (SNR) regions. The Rician noise distribution causes a non-zero minimum signal in the image, often referred to as t

Cancer är en otrevlig sjukdom, som drabbar många människor. Man söker ständigt nya och bättre sätt att bota patienter eller åtminstone lindra sjukdomens framfart. Ett vanligt sätt att behandla cancer är med strålning. Strålningen kan bestå av sk fotoner. Fotoner är samma slags partiklar som t.ex. vanligt ljus. Skillnaden är att de fotoner som används vid strålbehandling av cancer har högre energi "Purpose: The aim of this study was to investigate whether inversely planned intensity modulated radiation therapy (IMRT), using the clinical radiotherapy equipment at hand in our department, renders any advantages regarding dose distribution over conventional radiotherapy for head and neck cancer patients in the ARTSCAN (Accelerated RadioTherapy of Squamous cell Carcinoma in the head And Nec

Popular Abstract in Swedish Behandling med radionuklidterapi baseras på radioaktiva läkemedel, d.v.s. läkemedel som i sig består av ett radioaktivt ämne, eller som kopplats till en radionuklid. Den strålningsenergi som avges vid de radioaktiva sönderfallen absorberas i vävnad och ger en lokalt absorberad stråldos där läkemedlet tas upp. Viktigt är härvid att upptaget är högre i patologisk vävnad äIndividual-based determinations of the absorbed dose in radionuclide therapy largely rely on absolute measurement of the activity distribution and its redistribution over time. Scintillation-camera imaging is the most commonly employed measuring technique, applied in planar or SPECT mode, sometimes in combination with structural images from CT. In this thesis, methods for processing and analysis o

This thesis is focused on electronic cigarettes and the formulations (also known as e-juices) associated with these. The reason is that there have been countless studies on the health effects and nicotine delivery of normal cigarettes, but not as much on electronic cigarettes. This work aims to provide some insights into how electronic cigarettes behaves as nicotine delivery system. The overall re

Genome-wide association studies (GWAS) for biomarkers important for clinical phenotypes can lead to clinically relevant discoveries. Conventional GWAS for quantitative traits are based on simplified regression models modeling the conditional mean of a phenotype as a linear function of genotype. We draw attention here to an alternative, lesser known approach, namely quantile regression that natural

Context. The Gaia-ESO Survey (GES) is a large public spectroscopic survey at the European Southern Observatory Very Large Telescope. Aims. A key aim is to provide precise radial velocities (RVs) and projected equatorial velocities (v sin i) for representative samples of Galactic stars, which will complement information obtained by the Gaia astrometry satellite. Methods. We present an analysis to e

Atypical femoral fractures are insufficiency fractures in the lateral femoral diaphysis or subtrochanteric region that mainly affect older patients on bisphosphonate therapy. Delayed healing is often seen in patients with incomplete fractures (cracks), and histology of bone biopsies shows mainly necrotic material inside the crack. We hypothesized that the magnitude of the strains produced in the s
