Grammatik i traditionens eller framtidens tjänst?

Studiens syfte var att ta reda på hur grammatikmomentet tar sig uttryck i läroböcker för gymnasiet i kurserna svenska 1, 2 och 3. Syftet skulle uppnås genom att undersöka läromedlen med hjälp av en kvalitativ innehållsanalys, där fokus för analysen låg på att identifiera två olika grammatiska teorier: traditionell grammatik och systemisk-funktionell grammatik. Undersökningen visade att den traditi

Smoking and Breast Cancer

Ex-smokers are exposed to a higher breast cancer risk than are never smokers. This conclusion is based on a follow-up of the 10 902 women in the Malmö Preventive Project. The 31% higher incidence in ex-smokers remained statistically significant when other risk factors were taken into account in the analysis. In both smokers and ex-smokers there was an increased incidence of oestrogen receptor nega

Immuno Gene Therapy of Rat Brain Tumors with interferon-gamma transfected glioma cells

Immunotherapy is a new promising approach in cancer treatment. In the future, it will hopefully offer an alternative to existing brain tumors treatments, which are unable to cure. We have established an experimental, low immunogenic, brain tumor model in the rat. We have increased tumor cell immunogenicity with mutagen treatment or transfection of IFN-g. Mutagen treated glioma cells (tum-) could c

Effects of dopamine and excitotoxicity in experimental models of Huntington's disease

Huntington's disease (HD) is a hereditary neurodegenerative disorder caused by an expansion of a CAG repeat in the HD gene, that leads to dysfunction and death of striatal neurons. The pathogenetic mechanisms underlying HD are not known, but excitotoxicity and dopamine (DA) have been suggested to play a role. In this thesis, the effects of excitotoxicity and DA have been studied in striatal in vit

Mechanisms and time course of cell death in embryonic nigral tissue and intrastriatal transplants.

Parkinson’s disease (PD) is the second most common neurodegenerative disorder and severely affects about one in a hundred persons over the age of fifty years. In PD, there is a reduced striatal concentration of the neurotransmittor dopamine, mainly caused by a degeneration of the dopaminergic neurons in the substantia nigra. Transplantation of embryonic dopamine neurons has been developed as an al

Molecular studies of genetic changes in myxoid and round cell liposarcoma

Chromosomal translocations commonly result in the production of fusion genes and the fusion genes are often tumor-type specific. In myxoid and round cell liposarcomas (MLS/RCLS), almost 95% of the cases carry a t(12;16)(q13;p11). In the remaining 5% of the MLS/RCLS tumors, another translocation and fusion gene can be found, i.e. the t(12;22)(q13;q12). These translocations fuse CHOP on chromosome 1

Treatment process and outcome for long-term mentally ill patients in a comprehensive treatment program based on cognitive therapy

All patients admitted during a four-year period to a comprehensive, cognitive therapy based inpatient rehabilitation program for long-term mentally ill were invited to participate in the present study. A total of 28 patients were included. The patients were at admission and discharge assessed with regard to quality of life, symptoms, global functioning and target complaints. Every five weeks throu

Food selection and fitness optimisation in insects

To optimise fitness is a continuous process which assists species survival in changing environments. Choosing an optimal diet is an essential part of the optimisation process and a key element of optimal foraging theory. The relationship between food choice and fitness optimisation has been tested on three ground beetles and several collembolan species by using food items naturally occurring in th

Suicide in Severe Depression: A Longitudinal Case-Control Study

Suicide in Severe Depression. A Longitudinal Case-Control Study. The present thesis is based on a case-control study of suicide victims with a severe depression/ melancholia. All patients admitted to the Department of Psychiatry 1956-1969 who received this diagnosis on a multiaxial schedule (1206 patients) were followed up in two sessions to 1984 and to 1998 concerning suicide and general mortali

Neurohormonal Modulators in the Parathyroid Gland. Localization and regulation.

The occurrence and distribution of neurohormonal peptides, neuroendocrine markers and receptors in parathyroid nerve fibers and endocrine cells are described, using immunocytochemistry, in situ hybridization, image analysis and reverse transcriptase polymerase chain reaction. Immunocytochemical studies revealed that parathyroid glands of chicken, rat, guinea-pig, cat, dog and sheep contained adren

Clinical - cytogenetic correlations in malignant hematologic disorders

In the present thesis, clinicogenetic correlations are investigated in a large population-based series of acute myeloid leukemia (AML), myelodysplastic syndromes (MDS), acute lymphoblastic leukemia, and chronic myeloid leukemia, for which the karyotypes were analyzed at the same center. The karyotypic pattern, i.e. normal karyotype or 1, 2 or ³3 anomalies, does not differ between males and female

Ischemic Cell Death in the CNS - applications of a new in vitro model

Ischemic brain damage is a common cause of death and disability. A global ischemic insult is usually the result of a transient cardiac arrest while occlusion of cerebral blood vessels leads to focal ischemic lesions, commonly termed stroke. During the last decades our knowledge about the metabolic and cellular events leading to cell death following ischemia has expanded mainly due to experimental

Fungal Lectins. Molecular structure and function of a member of a novel lectin family.

Lectins defined as non-enzyme, non-immunoglobulin carbohydrate binding proteins, have been found in a wide variety of viruses, bacteria, fungi, plants and animals. Although lectins have been purified from more than 60 different species of fungi, the structure and biological functions of these proteins are not well known. I examined the molecular structure of a lectin (designated AOL) isolated from

Role of adhesion molecules and chemokines in TNF-alpha-induced leukocyte recruitment

Migration of leukocytes from the circulating blood into the extravascular tissue is a key component in inflammatory reactions. Leukocyte extravasation (rolling-activation-adhesion-transmigration) is strictly coordinated by adhesion molecules and chemokines expressed on cell surfaces and in tissues. Tumor necrosis factor-alpha (TNF-alpha) is pleiotrophic cytokine, which plays an important role in t

Ultrasound Examination in Infant Clubfoot with Special Emphasis on the Talonavicular and the Calcaneocuboid Joints

The purpose of the study was to develop an ultrasound (US) protocol for evaluating congenital clubfoot pathoanatomy before and during early treatment. By using 3 easily defined and reproducible US projections the talonavicular and the calcaneocuboid joints were assessed. Normal configurations of the relationships at these joints were obtained by investigating 54 healthy babies at the ages of 0, 4
