The studies presented in Papers I to VI illustrate several different aspects of the impact of vascular plants on methane emissions from northern natural wetlands. The subject has been approached on different scales, ranging from the study of microbial substrates in the vicinity of a single plant root, to an attempt to extrapolate some of the results to the entire northern hemisphere north of 50°N.

Evolutionary theory predicts the existence of relatively stable sex differences in partner preferences with, for example, males being more concerned with traits predicting high fertility and females with traits predicting high resource availability. We tested three predictions using personal advertisements from both traditional newspapers and internet dating services. In accordance with prediction

Study the relationship between inhalation of airborne particles in a pulp and paper mill and markers of inflammation and coagulation in blood.

PURPOSE: We investigated the prevalence and types of lower urinary tract dysfunction in children with vesicoureteral reflux grades III and IV, and related improved dilating reflux, renal damage and recurrent urinary tract infection to dysfunction. MATERIALS AND METHODS: A total of 203 children between ages 1 to less than 2 years with reflux grades III and IV were recruited into this open, randomiz

Haemophilia B is caused by a heterogeneous spectrum of mutations. Mutation characterization is important in genetic counselling, prenatal diagnosis and to predict risk of inhibitor development.

Context: Blood hemoglobin (Hb) declines with age in healthy elderly men, in whom decreasing testosterone has been regarded as part of normal ageing. However, the association between Hb and serum estradiol is incompletely known. Objective: To determine whether estradiol is associated with anemia/Hb and established determinants of Hb in elderly men without prostate cancer. Design, Setting and Partic

Welding fume consists of metal fumes, e.g., manganese (Mn) and gases, e.g., ozone. Particles in the respirable dust (RD) size range dominate. Exposure to welding fume could cause short- and long-term respiratory effects. The prevalence of work-related symptoms among mild steel welders was studied, and the occupational exposure to welding fumes was quantified by repeated measurements of RD, respira

Twenty 10- to 18-year-old children and adolescents with varying degrees of hearing impairment (HI) and hearing aids (HA), ranging from mild-moderate to severe, produced picture-elicited narratives in a spoken and written version. Their performance was compared to that of 63 normally hearing (NH) peers within the same age span. The participants with HI and NH showed similar patterns regarding intra

The Scandinavian Total Ankle Replacement (STAR) has been used widely in Europe and more recently in the United States. We studied the results of the single-coated and the double-coated STAR with long-term follow-up.

The observed increased risks of gastric cancer among first-generation immigrants compared to those in Swedes suggest the role of childhood environmental exposure in the risk of this disease.

To study the annual direct and indirect costs in systemic lupus erythematosus (SLE) and how age, disease manifestations, disease activity, and organ damage influence total costs and predicted costs for SLE.
