The effect of mandibular advancement device on pharyngeal airway dimension in patients with congestive heart failure treated for sleep apnoea.

Continues positive airway pressure (CPAP) is recommended for treatment of sleep apnoea (SA) in patients with congestive heart failure (CHF) but is not easily tolerated resulting in poor patient compliance. Mandibular advancement device (MAD) is designed to inhibit pharyngeal airway (PAW) obstruction and may be a valuable alternative. It has been proposed that MAD exerts its effect by increasing PA

On the role of the fusion protein DEK-NUP214 in leukemogenesis

The t(6;9) translocation is found in a subset of patients with acute myeloid leukemia (AML) and is associated with a poor prognosis. The translocation results in the formation of the DEK-NUP214 fusion protein containing almost the entire nuclear protein DEK and two thirds of the nucleoporin NUP214. The molecular mechanisms behind the leukemic conversion of cells expressing the fusion protein DEK-N

Pathophysiology and treatment of defective insulin secretion in diabetes

Defective insulin secretion is a central feature in diabetes mellitus and results from reduced pancreatic beta-cell mass as well as aberrant beta-cell function. The pathophysiology of diabetes is incompletely known, but a strong hereditary component is suggested. This thesis investigates the genetic and cellular basis for impaired insulin release by employing a number of cell-physiological and bio

Characterisation of the leukaemia-associated ETO homologues

Acute myeloid leukemia (AML) is commonly associated with balanced chromosomal translocations. Characteristically, these translocations lead to the fusion of two unrelated genes, resulting in the expression of an aberrant fusion protein. t(8;21) is one of the most common translocations found in patients with AML. It results in the expression of the chimeric protein AML1-ETO. AML1 is a transcription

Acute Otitis Media. Aspects of diagnosis and prophylaxis

Acute otitis media (AOM) is one of the most common childhood diseases and the most common causes of antibiotic treatment in small children. Most children will experience one or two episodes of AOM during preschool age but some will suffer from repeated attacks, they will become otitis-prone. Complications with severe, sometimes fatal infections such as acute mastoiditis and meningitis are nowadays

Dizziness and fear of falling: A behavioural and physiological approach to Phobic Postural Vertigo

Dizziness is a common problem and it often co-exists with anxiety. Level of anxiety is the best predictor of handicap for dizzy patients. There is diagnostic controversy and few treatment programs for such patients. These patients can be labeled as panic disorder with agoraphobia or by the concept of Phobic Postural Vertigo which is characterized by dizziness or imbalance in standing or walking de

Drug-related problems in the elderly - Interventions to improve the quality of pharmacotherapy

Introduction: Elderly people, in particular those residing in nursing homes, often use many drugs. In general elderly patients are at greater risk of experiencing drug-related problems (DRP), as they have multiple diseases, are using many drugs and have changed physiological status. Objectives: To describe the frequency of potential drug-related problems in the elderly and to evaluate different k

Computer Visualization in Participatory and Cognitive Engineering

This thesis tells the initiation story of a computer visualization methodology and a participatory engineering methodology. The two methodologies are tightly coupled and for the purpose of this thesis, as a unit, named Computer Visualization in Par-ticipatory Engineering (VIPE). VIPE aims at a concurrent focus on technical and economical as well as ergonomic demands, by means of advancing communic

Communication in Games and Decision Making under Risk

This thesis is divided into two distinct parts. The first part studies communication in games and the second part investigates individual decision making under risk. Chapters 2 – 4, co-authored with Ola Andersson, investigate communication and renegotiation in dynamic games. In Chapter 2, Bertrand supergames with non-binding communication are used to study price formation and stability of collus

Laser Diagnostics Applied to Lean Premixed Swirling Flames - Simultaneous Flow Field and Scalar Measurements

The work reported here includes experimental studies of lean premixed swirling flames. Various laser-based optical diagnostic techniques were used to collect information under different operational conditions. Combined flow- and scalar field measurements were performed at high repetition rates for detailed studies of the turbulent flames. A large part of the work presented concerns experimental

EFFECTOR T CELL HOMING TO THE SMALL INTESTINAL MUCOSA

The intestinal mucosa, including the intestinal epithelium and underlying lamina propria (LP), contains a large number of effector/memory T cells that are thought to play a central role in the generation and maintenance of mucosal immune responses and in maintaining mucosal integrity. The work in this thesis investigates the mechanisms regulating effector T cell recruitment to the small intestinal

Body Protein and its Change in Patients During Anti-Tumor Treatment

The purpose of this study was to investigate how total body protein and its fraction of body weight (body protein fraction) change in cancer patients during different anti-tumor treatments, and to see if these changes have any clinical significance in the form of prognostic value or correlation with disease course and tumor response. In 84 patients, 28 with lung cancer, 24 with gastrointestinal t

Arkitekturens kroppslighet. Staden som terräng

Beginning with the notion that spatial and material qualities of architecture set limits and create conditions for how we make use of it, the overall aim and ambition of this thesis is to develop this notion and to contribute to a deeper understanding of the relationships that are produced between the materiality of architecture and a bodily appropriation of it. To investigate this the thesis esta

The telomere binding proteins in yeast and their role in telomere maintenance

Telomeres are the end-structures of linear chromosome which are crucial for maintaining genome integrity. The telomeres prevent the DNA-repair machinery from recognizing the chromosome ends as double-strand breaks and from end-to-end fusions. The telomeres are composed by short repetitive units of TG-rich DNA and associated specialized telomere-binding proteins. Due to that replication only can

Vasodilator actions of EDHF and anandamide

Vasodilator responses to endothelium-derived hyperpolarizing factor (EDHF) and anandamide in isolated arteries were investigated. A combination of the potassium channel blockers charybdotoxin and apamin inhibits EDHF-mediated relaxations. Experiments in which charybdotoxin or apamin was substituted with other potassium channel inhibitors indicated that small- and intermediate-conductance calcium-a

Respiratory Sinus Arrhythmia and Emotion : Effects of pictorial stimuli and state anxiety

Respiratory sinus arrhythmia (RSA) refers to heart rate variations due to respiration, which results from parasympathetic nervous system activity mediated via the tenth cranial nerve, the vagus. Thus, the magnitude of RSA is considered as an index of cardiac vagal tone. This thesis explored RSA during emotional responding in healthy women and men. In the first two studies fear-relevant pictorial s

Synergistic interactions involving amphiphilic polymers in solution

The properties of hydrophobically modified cellulose derivatives in aqueous mixtures with various other molecules have been investigated. Mixtures of a hydrophobically modified polymer and alkali-sensitive, degradable surfactants gave rise to time-dependent viscosities. With time, the viscosity decreased continuously or went through a maximum, depending on the initial surfactant concentration. Th

On lumbar spine stabilization

71 consecutive posterolateral lumbar fusions without decompression or internal fixation were evaluated with a mean follow-up time of 3.5 (2-7) years. The diagnoses were spondylolysis-olisthesis in 43 cases, degenerative disc disease and/or facet joint arthrosis in 16 cases and pain post laminectomy/ decompression in 12 cases. 54/70 patients had a solid fusion. In the group with spondylolysis-olist
