Cell cycle regulatory proteins and miRNAs in premalignant lesions and breast cancer

Early diagnosis and reliable prognosis and treatment prediction of breast cancer will ultimately lead to a decreased mortality rate. This can be achieved by identification of prognostic and treatment predictive biomarkers, and by understanding the mechanisms behind early changes in the breast. The cell cycle is a closely controlled process, involving multiple components with regulation on several

Island biogeography and population divergence in the Skyros wall lizard

Islands are cradles for new biodiversity and provide natural laboratories for the study of population divergence. In my thesis, I investigated the role of different evolutionary processes in the population divergence in the Skyros wall lizard (Podarcis gaigeae), a species where islet populations have strongly diverged morphologies. I used replicate islet populations and their respective most proxi

Behaviour of Pine Sawflies in Relation to Pheromone-Based Pest Management

Pine sawflies (Hymenoptera: Diprionidae) are severe pine defoliators. This thesis investigated sawfly behaviour related to the use of pheromones in integrated pest management, including monitoring with pheromone traps and mating disruption. Neodiprion sertiferr females were placed on pine twigs in the field and 11–30 % of the females that remained on their twig after the first mating re-mated. Onl

OXYTOCIN AND VASOPRESSIN IN UTERINE ACTIVITY. Receptor-mediated agonism and antagonism with special regard to the aetiology and treatment of preterm labour and primary dysmenorrhoea.

With a view to the aetiology and treatment of preterm labour and primary dysmenorrhoea we studied the influence of sexual steroids on the plasma levels of oxytocin and vasopressin, effect of these peptides on uterine contractility in vitro and in vivo, receptor concentrations and antagonists to oxytocin and vasopressin. In postmenopausal women oestrogen increased the concentrations in plasma of bo

Male moth behaviour and perception in pheromone plumes

Behaviour of male moths and electrophysiological responses of male pheromone-specific olfactory receptor neurones were studied in two model species, the oriental fruit moth Grapholita molesta and the turnip moth Agrotis segetum. The studies were aimed at elucidating the relative importance of different mating disruption mechanisms. In a wind tunnel study of G. molesta, behavioural response to a r

Intra-Aneurysm Sac Pressure and Clinical Results after Endovascular Repair of Abdominal Aortic Aneurysms

AIM: The aim was to evaluate the results of endovascular aneurysm repair (EVAR) of abdominal aortic aneurysms (AAA) in terms of intra-AAA pressure and clinical outcomes. METHODS AND RESULTS: 0.014-inch guide-wire-mounted tip-pressure sensors were used for direct intra-aneurysm sac pressure measurement (DISP) through translumbar puncture of the AAA. Mean Pressure Index was calculated (MPI) as the p

Minimal conization with carbon dioxide laser for treatment of cervical intra-epithelial neoplasia

3,100 non-pregnant women and 85 pregnants were miniconized during the 15-year period ending 1994 . The outpatient procedure of minimal conization using a freehand-guided, high power 60W carbon dioxide laser focused to 0.1 mm in spot-size, giving high power density 165,000 W/cm2, produces single-piece tissue specimens for histological examination. The procedure is performed under local anaesthesia

Lactic acid bacteria fermentations in oat-based suspensions

This thesis deals with the fermentation characteristics of lactic acid bacteria (LAB) in oat-based suspensions, with formulation work of fermented products based on oat and with nutritional studies of these products. Changes in structure in terms of viscosity and ropiness were studied when exopolysaccharide (EPS)-producing LAB strains, namely, Lactobacillus delbrueckii subsp. bulgaricus NCFB 2772,

The role of public policy in advancement of product service systems

This article discusses developments in the area of product service systems (PSS) and the need to facilitate the proliferation of the PSS approach through public policies. The article argues that policies that establish the framework conditions for environmental improvement are preferable to detailed legislation as they favour environmentally superior PSS. However, there is also a need for more spe

Hypertension, blood pressure, cognition and cerebral blood flow in the cohort of "Men born 1914"

"Men born 1914" is a population based cohort study of the epidemiology of cardiovascular disease. Five hundred men, born 1914, were examined at the age of 68 and 185 of them were re-examined at 81 years of age. Examination included a medical and a psychological investigation, ultrasonographic measurement of carotid arteries, 24-hour ambulatory blood pressure monitoring, regional cerebral blood flo

Osäkerheter i variabler vid riskanalyser och brandteknisk dimensionering

The aim of this report is to present some of the variable uncertainties associated with the dimensioning of fire protection in buildings and risk analysis in buildings (with respect to fire). A method for assessing the fire frequency in a building is presented along with examples of how the assessed fire frequency can be improved using fire data from a specific building. The probability of differe

Function of contractile and cytoskeletal proteins in smooth muscle: Effects of hypertrophy and age and desmin removal in a transgenic animal.

In man, the urinary bladder responds to an urinary outflow obstruction with a pronounced dilatation and growth of the bladder wall. This clinical situation can be mimicked in rat by creation of a partial urinary outflow obstruction and the papers included in the present thesis use this animal model to address questions regarding the adaptive changes in the smooth muscle of the growing bladder. In

Pro- and anticoagulant activities of factor V

Coagulation factor V (FV) is activated by thrombin through proteolytic cleavage at Arg-709, Arg-1018 and Arg-1545. Upon thrombin activation, the active form of factor V (FVa) is formed. FVa functions as a cofactor to factor Xa in the conversion of prothrombin to thrombin during coagulation. Recently, it was shown that in addition to being a precursor form of the procoagulant FVa, FV functions as a

Rheumatoid Arthritis in a 10-Year Perspective, Outcome for Patients Followed from Early Disease

Rheumatoid arthritis (RA) is characterized by persistent inflammation, progressive joint damage and disability. This thesis describes the outcome after 10 years in a cohort of 183 RA patients (116 women, 67 men) recruited 1985-89. The mean age was 51 years and symptom duration 11 months at inclusion. Standardized clinical, biochemical and radiographic assessments were performed annually. Health st
