For treatment of systemic malignancies, when external radiation therapy is not applicable, radionuclide therapy can be an alternative. In this form of therapy, radionuclides are administered to the patient, often in a form where the radionuclide is labelled to a molecule that plays the active part in the localization of the tumor. Since the aim is to impart lethal damage to tumor cells while maint
Studded tyres wear surfaces of winter roads, generating inhalable airborne particles. In this study, four concrete road materials and two stud geometries were investigated in terms of wear, road material hardness and airborne particle concentration. The sliding contact between studded tyres and road materials was studied using a pin-on-disc machine in a clean chamber. The results show that the nor
AbstractModern radiotherapy aims to treat the decease while minimizing the radiation dose to the adjacent normal tissue, to minimize acute and late effects of the treatment.

The objective of this study is to explore the relationship between sleep disruption and increasing nightly temperatures. This has been done by comparing a normal year (2024) with a year characterized by extreme heat events (2018). The study intends to tell the difference in nights of insufficient sleep between the reference years. In Sweden, the relationship has been acknowledged by affected autho
Denna uppsats har haft som syfte att undersöka vad som sker när makars ekonomiska enhet plötsligt upphör genom att en av makarna avlider. Det är många praktiska åtgärder rörande bouppteckning, bodelning och arvskifte som kan försvåras genom gällande lagstiftning. Efterlevande make ärver med försteg framför gemensamma bröstarvingar enligt 3 kap 1 § ÄB. I de fall där det finns särkullbarn eller univThe main purpose of this thesis is to describe what happens when the economic unit of spouses ceases due to death. There are many practical actions regarding estate inventory, division of property and distribution of the estate that are complicated. The surviving spouse inherit his or her spouse’s estates before direct heirs, regulated in ÄB 3rd chapter 1 §, the Swedish inheritance code. Children
A method for calculating the wave load induced fatigue damage accumulated by a vessel sailing along the North Atlantic route (NAr) is presented. This method is based on the Palmgren-Miner additive rule and the rainflow cycle (RFC) count. For simplicity, the load the vessel experiences is assumed to be proportional to the encountered significant wave height process, H-s. The asymptotically normal c
Repeated ribs are frequently employed to promote turbulence and to enhance heat transfer in various ducts. In the present study, liquid crystal thermography was applied to the study of heat transfer from a square channel having one surface heated at uniform heat flux and roughened by repeated ribs. The continuous and truncated ribs, having square sections, with height-to-hydraulic diameter ratio o
Two-photon excited fluorescence spectroscopy has been performed at a microscopic scale in combination with normal, white-light microscopy. This gave simultaneously a spectral resolution of 20 nm and a temporal resolution of 20 ps, from a volume element less than 5 mu m in all three dimensions. The sample was excited with the light from a continuously mode-locked Ti:sapphire laser that was focused
Popular Abstract in Swedish Potatis är ett av våra viktigaste baslivsmedel, men erbjuder trots det stor variation. Traditionella recept varvas med nya innovationer i hushåll och restauranger, och inom livsmedelsindustrin processas potatisen till en rad olika produkter. Från traditionell kokt potatis med sås inom husmanskosten har våra matvanor förändrats radikalt. Ökade krav på snabb och enkel tilThe potato is one of our most important food crops, being sold in its natural state or processed into a wide range of products. Starch, by far the most abundant component in the tuber, is greatly affected by heat processing. Therefore it is logical to study starch thermal properties within the tuber tissue, although most previous studies have focused on starch-water model systems. One of the main
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
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
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
A systematic assessment of radiotherapy for cancer was conducted by The Swedish Council on Technology Assessment in Health Care (SBU) in 2001. The assessment included a review of future developments in radiotherapy and an estimate of the potential benefits of improved radiotherapy in Sweden. The conclusions reached from this review can be summarized as: Successively better knowledge is available o
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
PURPOSE. To examine in rodent models of retinitis pigmentosa (RP) the expression of the neuroprotectants metallothionein-I and -II and of megalin, an endocytic receptor that mediates their transport into neurons. METHODS. Gene and protein expression were analyzed in retinas of rd1 and rds mice and in those of RCS (Royal College of Surgeons) rats of various ages. Glial cell markers (cellular retina
Background: Previous studies in the rat have shown that the spatial organisation of the receptive fields of nociceptive withdrawal reflex (NWR) system are functionally adapted through experience dependent mechanisms, termed somatosensory imprinting, during postnatal development. Here we wanted to clarify 1) if mice exhibit a similar spatial encoding of sensory input to NWR as previously found in t
Trisomy 7 is a common finding in benign and malignant solid tumors, in several non-neoplastic lesions (for example, osteoarthritis and rheumatoid arthritis), and in apparently normal tissues as well, suggesting that the occurrence of +7 might be associated with factors other than the disease process itself. To find out whether the frequency of +7 varies with a patient's age, we cytogenetically ana
INTRODUCTION: Biomarkers play a crucial role in understanding Alzheimer's disease (AD) pathogenesis and treatment effects. However, comparing biomarker measures without standardization and appreciating their magnitude relative to the disease can be challenging. METHODS: To address this issue, we propose the CentiMarker approach, similar to Centiloid, which provides a standardized scale between nor
