BACKGROUND: An early age at menarche, a short menstrual cycle length, and a high age at first full term pregnancy or nulliparity are known risk factors for breast cancer. These risk factors have previously been reported to differ between breast cancer patients with and without a family history of breast cancer and also between breast cancer patients and controls. METHODS: Self-administered questio
BACKGROUND: The electrocortical background contains prognostic information in full-term asphyxiated newborn infants already during the first postnatal hours. In preterm infants with intra-ventricular hemorrhages (IVH) the background activity in EEG and amplitude-integrated EEG (aEEG) is depressed during the first days of life, and the extent of the depression correlates with the degree of IVH. How
AIMS: Lipoprotein lipase (LPL) is a major regulator of triglyceride clearance. A genetic variant of the LPL gene on chromosome 8p22, Asn291Ser, has previously been associated with dyslipidaemia and an increased frequency of cardiovascular disease as well as familial disorders of lipoprotein metabolism. The aim of this study was to test whether the phenotypic expression of the LPL Asn291Ser variant

In the present study, our objective was to quantify the daily duration of vibration exposure from ultrasonic scaling in dental hygienists and to compare different methods of self-estimates to time-recorded measurements. The exposure time was self-estimated by use of diary and interview methods in 10 subjects. We found that the measured total daily exposure time was limited, only on average 12 min,
The objective of this thesis is to propose a way to introduce social and cultural aspects of environmental degradation to the sustainable development debate. This is done by a reflexive and critical examination of environmental research as it has been applied to different spatial levels (and thus levels of social complexity). The spatial categories discussed are the city, the household and the lan

Recent empirical evidence strongly supports Jacobs's (1969) externality hypothesis that urban diversity provides a more favorable environment for economic development than urban specialization. In order to correctly gauge Jacobs's hypothesis, economic development should be understood as a result of innovations. Furthermore, a relevant diversity measure should take into account the degree of divers
Supermacroporous dextran gels (SDGs), having pores tens of micrometers in size and highly interconnected, were prepared from dextran macromonomer through radical polymerization at subzero temperatures and compared with dextran gels prepared at ambient temperature. Dextran macromonomer was synthesized via glycidyl methacrylate derivatization of dextran T500 in DMSO medium. The derivatization of dex
Persistent organic pollutants (POPs) can interfere with hormone activities and are suspected as endocrine disrupters involved in disorders, e.g. reproductive disorders. We investigated the possible relation between the actual integrated serum xenoestrogenic, xenoandrogenic and aryl hydrocarbon receptor (AhR) activities, and the sperm DNA damage and sperm apoptotic markers of 262 adult males (54 In
This thesis consists of five papers (Papers A-E) treating problems in non-parametric statistics, especially methods of kernel smoothing applied to density estimation for stochastic processes (Papers A-D) and regression analysis (Paper E). A recurrent theme is to, instead of treating highly positively correlated data as ``asymptotically independent'', take advantage of local dependence structures b
Dissolved Air Flotation (DAF) is a separation process in water and wastewater treatment. The removal function is based on reducing the density of the particle by producing aggregates of the particles and added micro-bubbles of air, thus lifting the aggregates to the water surface, where they can be removed as sludge. One parameter that is believed to be of crucial importance is fluid dynamics. The
OBJECTIVE: To improve identification of gravidas at risk for thrombosis. Venous thromboembolic complications are a major cause of maternal mortality during pregnancy. Factor V Leiden, which causes activated protein C resistance, is the most prevalent thrombophilia in white populations. However, selective screening for factor V Leiden has not been evaluated previously for identifying women who migh
We study the Dirichlet problem for p-harmonic functions (and p-energy minimizers) in bounded domains in proper, pathconnected metric measure spaces equipped with a doubling measure and supporting a Poincare inequality. The Dirichlet problem has previously been solved for Sobolev type boundary data, and we extend this result and solve the problem for all continuous boundary data. We study the regul
To investigate the cause of anomalously bright resonance lines of helium in the Sun, we have studied the magnitude of the enhancements and some proposals made to explain them. Calculations in new semiempirical solar models indicate that the resonance lines of helium are enhanced by factors of 2-5 for He I and between 2 and 9 for He II, depending on the elemental abundances assumed. These enhanceme
BACKGROUND: Glutathione transferases (GST) are a group of multifunctional enzymes important in the detoxification of many electrophiles and, in addition, fatty acid hydroperoxides, thus limiting tissue damage from oxidative free radical attack. Of the four classes of GST (alpha, mu, pi, and theta), a class mu isoenzyme, GST mu, is dominantly inherited and is expressed in approximately half of the
