Prostate-specific antigen (PSA) is a widely used marker for prostate cancer. In the literature, there are reports of nonprostatic expression of PSA that potentially can affect early diagnosis. However, the results are scattered and inconclusive, which motivated us to conduct a more comprehensive study of the tissue distribution of PSA and the closely related protein human glandular kallikrein 2 (h
Baddeleyit är en zirkoniumoxid som normalt sett inte är stabil i kiselmättade miljöer, utan då omvandlas till zirkon. Mitt arbete kommer att handla om ett extremfall då baddeleyit har påträffats i en kvartsit i södra Ghana. Zirkoner med baddeleyitomvandlingar hittas precis vid kontakten till en deformerad granit. Efter att ha undersökt både bergarten och de enskilda zirkonkornen i ljusmikroskop ocBaddeleyit is a zirconium oxide that normally is not found in silica rich environments, because it’s not stabile. It will rather react and form zircon. My paper will deal with an extreme case where the baddeleyit was found in a quartzite I the southernmost part of Ghana. Zircons with baddeleyit inclusions were found right above a contact with a deformed granite. After some studies on the rock and
This study explores the potential of thermophoresis as a method of translating silicon nanowires in a liquid. Thermophoresis, the movement of particles against a temperature gradient, provides a scalable method of manipulating the particles. Simulations conducted in COMSOL examined both spherical and cylindrical approximations of nanowires, focusing on their translation under varying temperature g
Hyperalphalipoproteinemia, as observed in patients who are either homozygous or heterozygous for cholesteryl ester transfer protein (CETP) deficiency, has been shown to be associated with striking changes in apolipoprotein size distribution, namely, of high-density lipoprotein (HDL) and HDL-like particles. We compared the effect of varying degrees of CETP activity on the HDL apolipoprotein profile
BACKGROUND : Recruitment and activation of eosinophils have been studied intensely in asthma and other allergic diseases. Less is known about the infiltration and behaviour of eosinophils during gastric ulcer healing. AIM : To examine the tissue infiltration and activation of eosinophils in the ulcer margin at different time points after ulcer induction (days 1-15). METHODS : Eosinophil peroxidase
Terrestrial ecosystem models (TEMs) contain the coupling of many biogeochemical processes with a large number of parameters involved. In many cases those parameters are highly uncertain. In order to reduce those uncertainties, parameter estimation methods can be applied, which allow the model to be constrained against observations. We compare the performance and results of two such parameter estim
The reconstruction of an object’s shape or surface from a set of 3D points plays an important role in medical image analysis, e.g. in anatomy reconstruction from tomographic measurements or in the process of aligning intra-operative navigation and preoperative planning data. In such scenarios, one usually has to deal with sparse data, which significantly aggravates the problem of reconstruction. H
Popular Abstract in Swedish Smärta kan betraktas som en varningssignal för annalkande eller redan inträffad vävnadsskada och har därigenom en uppenbar skyddsfunktion. Förmågan att genom snabba förändringar av pågående motorik avvärja en skadlig stimulering återfinns både hos människa och hos mer enkelt uppbyggda organismer långt ned på den fylogenetiska stegen. Den snabba bortdragning av handen soThe adult organization and postnatal development of the nociceptive withdrawal reflexes (NWR) of single hindlimb muscles were examined in decerebrate spinal rats using electromyography. In adult rats, NWR were found to perform highly organized sensorimotor transformations, with single muscles receiving excitatory cutaneous input from specific receptive fields (RF) whose distribution of sensitivity
Popular Abstract in Swedish Målet med avhandlingen är en ökad kostnadseffektivitet i förebyggande behandling av blödarsjuka. Allmän bakgrund om blödarsjuka och förebyggande behandling Blödarsjuka är en ärftlig sjukdom som endast uppträder hos män, även om anlaget överförs av kvinnliga bärare. I Sverige finns ungefär 700 blödarsjuka. Sjukdomen tar sig uttryck i en abnorm blödningsbenägenhet med fThe aim of the thesis was to increase cost-effectiveness in prophylactic treatment of haemophilia. Prophylaxis is effective to prevent bleedings and arthropathy, but the high cost limits its use. First, a new distribution system for clotting factor concentrates was implemented in Sweden to improve availability and reduce risks and costs. Next, optimization of dosing in prophylactic treatment was e
Patienter med misstänkt hjärtinfarkt genomgår ofta hjärtscintigrafi för att undersöka den regionala förändringen av blodets passage genom hjärtmuskeln. Orsaken till de sjukliga förändringarna kan antingen vara ischemi (nedsatt blodflöde pga förkalkningar i blodkärl) eller infarkt (celldöd i muskulaturen). För att utföra en hjärtscintigrafiundersökning används ett radioaktivt läkemedel (99Tcm-Sesta"The purpose of this study was to evaluate the benefit of commercial quantification software in perfusion SPECT imaging by simulating a group of patients and their corresponding SPECT acquisitions using a computer phantom and a Monte Carlo program. Based on decisions from experienced physicians and their visual interpretation of the simulated patient images, without and with addition of the i
The Swedish sound string /at/ (graphically: att) is associated with two grammatical functions: a) (part of) a subordinate conjunction and b) as an infinitive marker. Previous studies connect final lengthening and pauses with prosodic and syntactic boundaries in spoken discourse. Following these findings, this pilot study, with 5 short spontaneous discourses from 3 male speakers shows a correlation

This thesis is based on five papers (A-E) treating estimation methods for unbounded densities, random fields generated by Lévy processes, behavior of Lévy processes at level crossings, and a Markov random field mixtures of multivariate Gaussian fields. In Paper A we propose an estimator of the location parameter for a density that is unbounded at the mode. The estimator maximizes a modified lik
IgA deficiency developed in a 2-year-old boy with aplastic anaemia who received a bone-marrow graft from his HLA-identical, 6-year-old, IgA-deficient sister. Southern blot analysis revealed the presence of alpha-genes in both children, thus suggesting a defect of lymphocyte stem-cell differentiation as a cause of IgA deficiency. Tissue typing showed homozygosity of HLA A1, B8, DR3, the haplotype a
The appearence of quantum chaos in the excited rapidly rotating nucleus is studied in a simple nuclear model, consisting of the cranked Nilsson model with a schematic two-body interaction added. Chaos is found to smoothly set in at a much lower excitation energy in normal-deformed 168Yb than in superdeformed 152Dy. A dynamical sign of chaos is a saturation of the standard deviation of the E2-stren
Pulsating flow through bifurcations are of general interest. In the human body such flows are also very common; for example in blood vessels and the respiratory tract. The characteristics of the flow in arteries have been related to the process of atherogenesis, based on the observation that the initial manifestation of the process is observed at certain common locations, i.e., near bifurcations i

Limited-slip differentials (LSDs) are commonly used in high performance vehicles to im- prove handling by reducing differential speed and balancing torque between the driving wheels. BorgWarner develops electronically activated LSDs and Electric Cross Differen- tials (eXD), which dynamically control torque distribution to improve traction and vehicle performance. However, current electrically acti
Crocodilians are among the most vocal non-avian reptiles. Adults of both sexes produce loud vocalizations known as ‘bellows’ year round, with the highest rate during the mating season. Although the specific function of these vocalizations remains unclear, they may advertise the caller's body size, because relative size differences strongly affect courtship and territorial behaviour in crocodilians
