Multi-level characterization of host and pathogen in Helicobacter pylori-associated gastric carcinogenesis
(2014-11-06)Today, more than half of the world’s population is infected with Helicobacter pylori, and two to three per cent of these will develop gastric cancer associated with this infection. Gastric cancer is today the third largest ... -
Cytomegalovirus Infection in Heart and Lung Transplant Patients with focus on long-term outcome
(2014-11-06)Cytomegalovirus (CMV) infection is a common opportunistic infection after heart and lung transplantation. The aims of this thesis were to relate the incidence and severity of CMV infection and disease to different forms ... -
Profiling of Small Intestine Neuroendocrine Tumors
(2014-11-04)Small intestine neuroendocrine tumors (SI-NETs) are malignant neoplasms usually presenting with disseminated disease and symptoms of hormone overproduction. Radical surgery is curative but can only be performed for localized ... -
Consequences of meticillin-resistant Staphylococcus aureus (MRSA) acquisition. Patient experiences and interactions in health care and daily life.
(2014-11-04)Aims. The overall purpose of this thesis was to follow up the consequences of guidelines installed to prevent transmission of MRSA in healthcare from the patients’ point of view and subsequent consequences for everyday ... -
Biolubrication: Structural investigation of lubricin and its glycosylation
(2014-11-04)The sliding articular cartilage surfaces of the human diarthrodial joints are surrounded by biolubricating synovial fluid (SF), creating a perfect low friction biological biobearing structure with excellent lubrication ... -
Pathophysiological impact of targeting the ROS-p53 axis
(2014-10-21)The goal of this PhD thesis was to define the importance of the interplay between reactive oxygen species (ROS) and their activation of the tumor suppressor p53 in development and disease. We addressed this question using ... -
Development of novel vaccine strains of Vibrio cholerae and studies on the role of serotype in epidemic spread of cholera
(2014-09-26)Cholera, caused by bacterium Vibrio cholerae O1, is a severe diarrheal disease with an estimated 3-5 million cases and more than 140 000 deaths every year particularly affecting children under 5 years of age. It can be ... -
Microbiota of the alimentary tract of children - implications for allergy and inflammatory bowel disease
(2014-09-19)Allergy, which is the most common chronic disease in Swedish children and adolescents, is associated with a high standard of living and Western lifestyle. According to the hygiene hypothesis, allergy is due to inadequate ... -
Neural stam cells, TLX, and Neuroblastoma
(2014-09-19)Neuroblastoma (NB) is one of the most commonly diagnosed extracranial tumors in children below five years of age. Moreover, NB accounts for almost 12-15% of all childhood cancer related fatalities. To date, the origin of ... -
Molecular factors influencing epithelial-mesenchymal transition in breast cancer
(2014-08-22)Epithelial-mesenchymal transition (EMT) is a developmental process defined by loss of epithelial characteristics and acquisition of mesenchymal phenotype. EMT or similar processes are also implicated in carcinoma cell ... -
Studies on interactions of norovirus capsid protein with fucosylated glycans and galactosylceramide as soluble and membrane bound ligands
(2014-05-19)Noroviruses (NVs) are among the most common viral pathogens which target the gastrointestinal (GI) tract and cause severe diarrhea, vomiting and episodes of abdominal cramps with fever. Millions of people around the world ... -
Mediator and its role in non-coding RNA and chromatin regualtion
(2014-05-15)Mediator is a multiprotein complex required for the regulation of RNA Polymerase II (Pol II) transcription. Mediator transmits regulatory signals from activators and repressors to the Pol II machinery at the promoter, but ... -

Fluoroquinolone resistance in the environment and the human gut – Analysis of bacterial DNA sequences to explore the underlying genetic mechanisms
(2014-04-04)Fluoroquinolones (FQs) are synthetic, broad-spectrum antibiotics that target type II topoisomerases. High-level resistance is often caused by mutations in the target genes of FQs, especially in gyrA and parC. In contrast, ... -
Initiation of Mammalian Mitochondrial DNA Replication
(2014-04-04)Mitochondria produce most of the adenosine triphosphate required in a eukaryotic cell and they contain their own genome. The mitochondrial DNA (mtDNA) is a double stranded circular molecule that codes for proteins required ... -
