The genomic landscape of core-binding factor acute myeloid leukemias

Acute myeloid leukemia (AML) comprises a heterogeneous group of leukemias frequently defined by recurrent cytogenetic abnormalities, including rearrangements involving the core-binding factor (CBF) transcriptional complex. To better understand the genomic landscape of CBF-AMLs, we analyzed both pediatric (n = 87) and adult (n = 78) samples, including cases with RUNX1-RUNX1T1 (n = 85) or CBFB-MYH11

Helicobacter pylori infection, chronic corpus atrophic gastritis and pancreatic cancer risk in the European Prospective Investigation into Cancer and Nutrition (EPIC) cohort : A nested case-control study

The association between H. pylori infection and pancreatic cancer risk remains controversial. We conducted a nested case-control study with 448 pancreatic cancer cases and their individually matched control subjects, based on the European Prospective Investigation into Cancer and Nutrition (EPIC) cohort, to determine whether there was an altered pancreatic cancer risk associated with H. pylori inf

The Role of Smoking and Diet in Explaining Educational Inequalities in Lung Cancer Incidence.

Background Studies in many countries have reported higher lung cancer incidence and mortality in individuals with lower socioeconomic status. Methods To investigate the role of smoking in these inequalities, we used data from 391 251 participants in the European Prospective Investigation into Cancer and Nutrition study, a cohort of individuals in 10 European countries. We collected information on

Impact of Human Papillomavirus (HPV)-6/11/16/18 Vaccine on All HPV-Associated Genital Diseases in Young Women.

Background The impact of the prophylactic vaccine against human papillomavirus (HPV) types 6, 11, 16, and 18 (HPV6/11/16/18) on all HPV-associated genital disease was investigated in a population that approximates sexually naive women in that they were "negative to 14 HPV types" and in a mixed population of HPV-exposed and -unexposed women (intention-to-treat group). Methods This analysis studied

Transcriptional regulation in neuroblastoma cells under normoxic and hypoxic conditions

Popular Abstract in Swedish Neuroblastom, när utvecklingen går fel Neuroblastom är en tumörsjukdom som drabbar små barn och i Sverige diagnosticeras ungefär 14 barn med neuroblastom varje år. Neuroblastomtumörerna utvecklas under anläggningen av det sympatiska nervsystemet, som är en del av det icke-viljestyrda nervsystemet och har till uppgift att anpassa kroppens svar på stress och fara genom atThe childhood malignancy neuroblastoma develops from early cells of the sympathetic nervous system (SNS), and the tumors often produce catecholamines. Neuroblastoma cells retain several characteristics of immature sympathetic cells including the expression of a number of transcription factors normally expressed during embryogenesis. The genesis of the SNS requires the correct expression pattern of

Thermodynamics and Structure of Plate-Like Particle Dispersions

Popular Abstract in English Most people see chemistry as an abstract and complicated subject because it deals with species that can not be seen with bare eyes. But if one think about it, chemistry is everywhere! Chemical processes happen all around you and inside you everyday : there is chemistry in the human body where proteins play a great role, in shampoo bottles, the toothpaste, in the cement A considerable amount of mineral particles are found to have a plate-like shape. The work in this thesis concerns theoretical investigations, using Monte Carlo method, of the properties of such particles in aqueous solutions. The objectives were first to create a model that could capture the essential physics of clay suspensions and also to understand the role of thermodynamics in certain chemical

Role of TLR4 in Escherichia coli urinary tract infection

Popular Abstract in Swedish Urinvägsinfektioner är en av våra vanligaste infektionssjukdommar. De orsakas främst av den Gramnegativa bakterien Escherishia coli. Normalt hålls urinvägarna sterila av ett effektivt försvar med utsöndring av antimikrobiella faktorer i urinen, men även urinflödet i sig är en viktig faktor i försvaret mot infektioner. Vissa bakterier klarar dock att etablera sig trots dIn this thesis we have used P fimbriated E. coli as a model to investigate the mechanisms of bacterial recognition and cell activation by the urinary tract (UT) epithelium. We show that Toll like receptor 4 (TLR4) is crucial for the recognition and host response to P fimbriated E. coli. This response was independent of LPS and did not require CD14. TLR4 was abundant on epithelial cells throughout

Effects of Past and Current Land Use on Biodiversity: from a semi-natural grassland on Öland (Sweden) to a European perspective

Popular Abstract in French L'inquiétude grandit quant à la perte de la biodiversité liée aux changements d'utilisation des terres, l’effet de cette perte sur les services écosystémiques fournis par les communautés naturelles et semi-naturelles et, finalement, la menace que cela pourrait entraîner sur le bien-être de l’Homme. Ce travail de thèse examine l'impact de l'utilisation des terres présenteConcerns are increasing about the loss of biodiversity under land use change and how this will affect the ecosystem services provided by natural and semi-natural communities and consequently how this will threaten human well-being. The thesis examines the impact of present and past land use on different aspects of biodiversity; namely species diversity, traits and functional diversity and on ecos

Neuroblastoma Cell Differentiation: The Role of Neurotrophin Receptor Signaling and N-myc Expression

Popular Abstract in Swedish Neuoroblastom är en av de tumörformer som oftast drabbar små barn. Eftersom tumörer lyckligtvis är relativt ovanliga hos barn drabbas inte fler än i genomsnitt 14 barn årligen av neuroblastom i Sverige. Tyvärr finns dock, trots den effektiva behandling som kunnat arbetas fram för många andra barncancerformer, idag ingen verksam behandling att tillgå för så många som hälNeuroblastoma is a tumor of sympathetic nervous system derivation, mostly afflicting young children. This thesis is focused on a group of receptor proteins for neurotrophic factors, the Trk family, and on N-Myc, a transcription factor, all important in the formation of the sympathetic nervous system as well as in determining neuroblastoma patient outcome. Expression of trkA and trkC is linked to f

Coffee and tea intake and risk of brain tumors in the European Prospective Investigation into Cancer and Nutrition cohort study.

BACKGROUND: In a recent US cohort study, total coffee and tea consumption was inversely associated with risk of glioma, and experimental studies showed that caffeine can slow the invasive growth of glioblastoma. OBJECTIVE: The objective was to examine the relation between coffee and tea intake and the risk of glioma and meningioma in a large European cohort study, the European Prospective Investig

Ränteavdragsbegränsningar - reglernas bakgrund, tillämpning och framtid

Den 1 januari 2009 trädde en ny lag ikraft som begränsar avdragsrätten för ränta i vissa fall. Lagen kom som en reaktion på ett av Skatteverket uppmärksammat skatteupplägg som beräknades minska den svenska skattebasen med miljardbelopp. Skatteverket tog initiativet till lagstiftningen då man ansåg det nödvändigt att förhindra skatteplanering inom koncerner där ränteavdrag utnyttjas för att överfJanuary 1, 2009 a new legislation entered into force which limits the deductibility of interest in some cases. The law came in response to an observed tax evasion structure which expected to decrease the Swedish tax base by billions. The Swedish Tax Agency initiated the legislation since they deemed it necessary to prevent tax avoidance within company groups where interest deductibility was used

The aim of this study was to create models for describing the pharmacokinetics of monoclonal antibodies used for radioimmunotherapy.Method: Two models, based on very different modeling approaches, are presented in this

Consensus guidelines for lumbar puncture in patients with neurological diseases

Introduction Cerebrospinal fluid collection by lumbar puncture (LP) is performed in the diagnostic workup of several neurological brain diseases. Reluctance to perform the procedure is among others due to a lack of standards and guidelines to minimize the risk of complications, such as post-LP headache or back pain. Methods We provide consensus guidelines for the LP procedure to minimize the risk

Exposure to bacterial products lipopolysaccharide and flagellin and hepatocellular carcinoma : A nested case-control study

Background: Leakage of bacterial products across the gut barrier may play a role in liver diseases which often precede the development of liver cancer. However, human studies, particularly from prospective settings, are lacking. Methods: We used a case-control study design nested within a large prospective cohort to assess the association between circulating levels of anti-lipopolysaccharide (LPS)

Somatic mutations reveal asymmetric cellular dynamics in the early human embryo

Somatic cells acquire mutations throughout the course of an individual's life. Mutations occurring early in embryogenesis are often present in a substantial proportion of, but not all, cells in postnatal humans and thus have particular characteristics and effects. Depending on their location in the genome and the proportion of cells they are present in, these mosaic mutations can cause a wide rang

Cartilage oligomeric matrix protein contributes to the development and metastasis of breast cancer

Cartilage oligomeric matrix protein (COMP) is a soluble pentameric protein expressed in cartilage and involved in collagen organization. Tissue microarrays derived from two cohorts of patients with breast cancer (n=122 and n=498) were immunostained, revealing varying expression of COMP, both in the tumor cells and surrounding stroma. High levels of COMP in tumor cells correlated, independently of
