Popular Abstract in Swedish Cellerna I vårt immunförsvar hjälper oss att eliminera olika typer av infektioner orsakade av parasiter, bakterier och virus. Ibland klarar dessa celler även av att ta bort tumörceller, kroppsegna celler som börjat att dela på sig okontrollerbart. Det måste betyda att cellerna i immunförsvaret kan se skillnad på kroppsegna celler och främmande celler och strukturer (antThe present study deals with natural killer (NK) T cells restricted to the antigen presenting molecule CD1d. NKT cells have been suggested to play a role in many diverse immunological situations such as clearance of different pathogens, protection against certain tumors, regulation of autoimmune reactions and as a link between innate and adaptive immune responses. NKT cells are in many respects un

The conventional inversion of surface waves depends on modal identification of measured dispersion curves, which can be ambiguous. It is possible to avoid mode-number identification and extraction by inverting the complete phase-velocity spectrum obtained from a multichannel record. We use the fast simulated annealing (FSA) global search algorithm to minimize the difference between the measured ph

Popular Abstract in Swedish Bukspottkörteln, pancreas, är ett viktigt organ för ämnesomsättningen. Dess viktigaste funktioner är att tillverka enzymer och bikarbonat som utsöndras till tolvfingertarmen, duodenum samt hormoner som utsöndras till blodbanan. De viktigaste enzymerna är amylas som bryter ned olika sockerarter och stärkelse, lipas som bryter ned fett och trypsin som bryter ned proteinerThe pancreas is a central organ in the digestion of food as well as in glucose metabolism. Its two major functions are exocrine and endocrine secretion. These are meticulously regulated processes that depend on hormonal response to gastrointestinal contents and blood glucose levels through feedback mechanisms, but also to the status of pancreas in health and diseases. The present thesis aimed at f

Popular Abstract in Swedish Bröstcancer är den vanligaste cancerformen hos västerländska kvinnor. I Sverige kommer var tionde kvinna att drabbas av bröstcancer, vilket motsvarar drygt 5000 kvinnor om året. Dödligheten i bröstcancer är 30%. Detta innebär att en tredjedel av de som drabbas kommer att dö av sin sjukdom. Det är dock inte själva tumören i bröstet som dödar eftersom denna i princip alltBreast cancer is one of the most common cancer forms in the industrialized world. Only in Sweden, nearly 6000 women are diagnosed with breast cancer each year and 1/3 of them eventually succumb to the disease. Wnts are a family of genes that have been implicated in many human tumours, so far mainly studied in colorectal cancer where activated Wnt signalling occurs in a vast majority of tumours. Wh

Popular Abstract in Swedish Vi kommer dagligen i kontakt med läkemedel i olika former, antingen som den kräm som vi smörjer in vårt onda knä eller Treon somliga tar på söndagsmorgon. Många av dessa produkter kan se enkla ut men är ofta resultatet av mycket forskning och för att förstå hur arbetet som utgör den här avhandlingen är kopplat till en Treo, så tänkte jag att vi ska börja med att förklarAn important issue within the pharmaceutical world today is the increasing number of poorly soluble drugs. These often show a low bioavailability and a susceptibility to varying conditions in the intestine. Hydrophobically modified poly (acrylic acid) (HMPAA), commercially available as Pemulen TR2, has shown promising abilities to control the release of especially poorly soluble substances. In thi

Popular Abstract in Swedish Elakartade (maligna) blodsjukdomar uppstår i den blodbildande benmärgen, vilken är innesluten i hålrummen i de skelettdelar som kan sägas täckas av en badmössa och en gammaldags baddräkt. En av de celltyper som bildas i benmärgen är plasmacellen, en vit blodkropp som utgör mindre än 2% av benmärgscellerna och som tillverkar specifika antikroppar vid infektioner. Vid monAcquired genetic changes have proved to be of diagnostic and prognostic importance in different hematologic malignancies as well as in some solid tumor types. However, although multiple myeloma (MM), an incurable disease, and its proceeding stage monoclonal gammopathy of undetermined significance (MGUS) are quite common, little is known about the karyotypic features of these plasma cell dyscrasias

Popular Abstract in Swedish I denna avhandling presenteras fyra nya metoder för att automatiskt mäta hjärtats förmåga att pumpa ut blod i kroppen, mäta storleken på en hjärtinfarkt samt mäta hur stor del av hjärtmuskeln som riskerade att dö vid hjärtinfarkten. Dessa nya metoder kan användas för att minska skillnader mellan mätningar gjorda av olika läkare, på olika sjukhus och i olika forskargruppIn this thesis four new algorithms are presented for automatic segmentation in cardiovascular magnetic resonance (CMR); automatic segmentation of the left ventricle, myocardial infarction, and myocardium at risk in two different image types. All four algorithms were implemented in freely available software for image analysis and were validated against reference delineations with a low bias and hig

Popular Abstract in Swedish Hos människan lever en rad mikroorganismer som tillsammans utgör normalfloran. Normalfloran återfinns på alla kroppsytor, det vill säga huden och slemhinnorna i munnen, svalget, magsäcken, tunn- och tjocktarmen, vagina och urinrörsmynningen. Samspelet mellan människokroppen och mikroorganismerna utsätts dagligen för påfrestningar. En sådan naturlig påfrestning är de sjuThis thesis is concerned with a family of bacterial surface proteins expressed by different strains of the anaerobic Gram-positive, commensal and human pathogen Peptostreptococcus magnus. These proteins have been studied with respect to their role in virulence, function, structure, and evolution. Strains isolated from patients with vaginosis have previously been shown to be associated with express

Transplantation of embryonic dopaminergic neurones can ameliorate symptoms in Parkinson’s disease, but a major obstacle for clinical transplantations to overcome is the low survival (typically 5-10%) of implanted nigral neurones. If cell death in nigral grafts can be prevented, less embryonic tissue would be needed per transplantation session and hence more patients could receive intracerebral gra

Hjärntumör inklusive glioblastom.Glioblastom är den vanligaste sortens hjärntumör bland vuxna och samtidigt den mest elakartade. Glioblastom drabbar cirka 550 personer årligen i Sverige. När tumören upptäcks är behandlingen först operation för exakt diagnos och med syfte att avlägsna så mycket som det går av tumören, utan att orsaka skada för patienten, annars görs en diagnostisk biopsi. StandardbAbstractBackground: Glioblastoma is the most common malignant brain tumor. Operation with maximal resection, if feasible, otherwise biopsy followed by radiotherapy and chemotherapy with temozolomide is standard therapy. The prognosis remains poor, with median overall survival being 15 months despite therapy. Improved monitoring and treatment response assessment will be important when seeking to im

Sedan 1970-talet har antalet rapporterade cancerfall dubblerats, dels på grund av förändrade levnadsvanor och dels på grund av bättre screeningmetoder som upptäcker cancern i tidigt skede. Tidig upptäckt av cancern i kombination med utvecklad cancerbehandling har bidragit till att risken för att avlida av cancer har minskat. Cancerbehandling sker huvudsakligen genom operation, strålbehandling elleAim: The tomotherapy system offers two radiation techniques, TomoHelical (TH) and TomoDirect (TD). The aim of this master thesis was to evaluate TD as a treatment alternative mainly by comparing TD treatment plans with 3DCRT plans and comparing TD plans with TH plans, separately, in the thoracic and abdominal regions. An additional aim was to examine if the current patient specific quality control

This study has examined Liberian disabled women’s participation in peace and security processes through the lens of the United Nations Security Council Resolution (UNSCR) 1325. The aim was to gain new insights into Liberian disabled women’s experience in peace and security processes, since the overarching research problem is the lack of insight into the disabled women’s experiences as participants

Antikroppar har ett brett användningsområde med stor potential men det är svårt att skapa stabila lösningar. Den strukturella stabiliteten är en viktig faktor när man väljer läkemedelskandidater, och i de tidiga utvecklingsstadierna görs prediktiva undersökningar för att ta reda på varje kandidats stabilitet och utvecklings-potential. Därmed är det av största intresse att utvärdera hur antikropparA great challenge during early development of medicinal antibodies is to determine the stability of the candidates. This is required to be able to select the candidates with the greatest developability. The stability of the candidates can be estimated using different orthogonal techniques and the aim of this investigation was thus to use orthogonal techniques for the investigation of conformationa

Over the last decade the music festival sector grew enormously: in 2008 over a million festivalgoers gathered in the UK to share music and companionship. However in doing so musicfestivals generate large volumes of waste streams and consume large quantities of resources. Amusic festival of more than 40 000 people will produce in the order of 2000 tons of CO2e –with audience transportation and on s

Oilseed rape fields are a very common crop in the agricultural landscape of southern Sweden, and they can harbour surprisingly many insect species. Some of them are herbivores that feed on various parts of the oilseed rape plant, others are natural enemies of the herbivores, and even more species are tourists from the surrounding landscape.
