A quarter of a century has elapsed since the catastrophe at the nuclear power plant in Chernobyl. The radioactive fallout affected all the European countries and most severely the three countries of Belarus, Russia and Ukraine. In the aftermath of this devastating event, the scientific knowledge on the various radiological impacts of such a large scale accident and means to remediate these impacts

It is known that parasympathetic, sympathetic and sensory nerves innervate the islets and that these nerves harbor both classical neurotransmitters and neuropeptides. However, the neural influence on islet hormone release is complex and not yet fully understood A recently discovered pancreatic neuropeptide is pituitary adenylate cyclase-activating polypeptide (PACAP). The aim of this thesis was to

This dissertation investigated electrophysiological measures of individual differences in toddlers’ ability to learn novel object labels and process familiar object words and their referents. The studies measured both visual and auditory event-related potentials (ERPs) in response to pictures of objects and words in a longitudinal sample of 20- to 24-month-olds, an age of dynamic vocabulary develo

Although advances in neonatal care have resulted in increased survival rates among extremely preterm infants (born < 28 gestational weeks), they still face substantial morbidity risks during the neonatal period. The question of possible later outcomes is a key issue faced by health care professionals working with these infants. Objectives The objective of the present thesis was to explore develo

The work presented in this dissertation addresses two main topics: (i) graphene supported nanoparticles and their stability upon gas adsorption, and (ii) intercalation of different molecules under graphene and their reactions under graphene. From an interplay of X-ray photoelectron spectroscopy, scanning tunneling microscopy, low energy electron diffraction, and density functional theory an atomic

The aims of this thesis were to investigate factors of significance for the development of acute confusional state (ACS), the confusional episodes, the lived experiences of having been confused in elderly patients admitted for emergency or elective surgery in orthopaedic care. A further aim was to investigate the nurses’ view of the ACS and the encounter with patients who developed ACS. A case stu

There is a persisting controversy concerning the definition, etiology and pathogenesis of Barrett's esophagus. The dramatic and parallel increase in the incidence of esophageal and junctional adenocarcinoma over the past decades justifies an evaluation of the pathophysiology of premalignant metaplastic changes of the esophagus and the gastroesophageal junction. Patients were evaluated with upper G

Long-term studies of birds play an important role in the understanding of quantitative traits in natural populations. The relative ease by which individual birds can be monitored and caught in the wild enable us collect detailed information from individuals throughout their life time, sometimes from several generations in a population. In this thesis I describe the utilization of a great reed warb

The aim of this thesis was to assess quality of life in patients with varying degrees of lower limb ischaemia before and after revascularisation, to assess quality of life in relation to the degree of ischaemia and the respondents’ sense of coherence (SOC) and in comparison with a healthy control group, and to compare two different quality of life instruments regarding their usefulness as outcome

Triglycerides in the adipocyte are hydrolysed by means of three consecutive reactions through the combined action of two lipases: hormone-sensitive lipase (HSL) and monoglyceride lipase (MGL). HSL catalyses the first and rate-limiting step, i.e. the hydrolysis of triglycerides to diglycerides, and the subsequent hydrolysis of diglycerides and monoglycerides. However, MGL is needed to assure comple

Modules are independently folding protein domains defined on the gene level. The epidermal growth factor-like (EGF) modules are involved in protein-protein interactions and are found in numerous membrane proteins and extracellular proteins, including many proteins of the blood coagulation system. A subset of the EGF modules binds one Ca²⁺ with an affinity that is often influenced by the

The thesis deals with plasticity in terms of neurotransmitter expression and survival of neurons in the adult enteric nervous system (ENS). Several motility disorders have been suggested to originate in developmental defects, neurodegeneration, or insufficient innervation by the ENS. Normal distribution of the interstitial cells of Cajal (ICC), found in close relationship to enteric neurons, is al

The spectra of symbiotic stars are shown to frequently contain numerous fluorescence lines caused by Photo-excitation by Accidental Resonance (PAR). So far, most work involving fluorescence in stellar spectra has been assigned to the search of new PAR mechanisms, which can explain the presence of certain emission lines. This is taken a step further as the PAR pumped emission lines are analyzed to

The overall aim of this study was to develop and evaluate a measurement system for computed radiography (CR) and Picture Archiving and Communication Systems (PACS), permitting measurements of long distances and angles in and between related images. The developed measurement system, which was based on the QUESTOR Precision Radiography (QPR) system, was applied to the weight-bearing knee with specia

This study investigated psychosocial environment, needs, quality of life and social network for persons with severe mental illness in supported housing in the community. Eighty-three persons with severe mental illness living in three different types of housing setting accepted to participate in the interviews, which took place between December 1997 and April 2000. These settings were: inpatient se

Popular Abstract in English In an organism the DNA contains the entire biological information that is needed to be able to exist and function. Those segments, also known as DNA sequences are a genetic code, which is further packaged into units called genes. The entity of all genes is called genome. Today we know, that only a small proportion of genes encode for proteins, which are responsible for More than 90% of DNA does not code for proteins and for a long time these sequences were referred to as “junk DNA” due to their unknown purpose. With the advent of new technologies it is now known, that the non-coding part of the genome is of great importance for regulating gene expression and is therefore indispensable. Transposable elements comprise about 50% of the genome and co-exist as symbio

Human milk contains a vast array of bioactive molecules, with nutritional and protective functions. This thesis describes the effects of a human milk protein complex, MAL, on tumour cells and bacteria. During our studies on the anti-adhesive properties of human milk we observed that a milk fraction killed tumour cells. The morphology of the cells indicated apoptotic cell death and this was verifie
