Density-dependent reproductive output in relation to a drastically varying food supply: getting the density measure right
When a limiting resource (e.g. food) varies drastically between years, and population density is measured in the conventional way as individuals per area, demographic processes such as productivity and survival may erroneously be considered density-independent. We tested the hypothesis that if the variation in a limiting resource is not taken into account in the density measure, this may lead to e
Prevalence of self reported hip symptoms, relations to age, gender, pain, stiffness, weakness and other joint disorders
Incidence and risk of venous thromboembolism in patients with verified arterial thrombosis: a population study based on 23 796 consecutive autopsies

Seasonality of month of birth differs between type 1 diabetes patients with pronounced beta-cell autoimmunity and individuals with lesser or no beta-cell autoimmunity
Objective: To establish whether children with type 1 diabetes mellitus (T1D) with signs of pronounced beta-cell-specific autoimmunity as reflected by high autoantibody titers or positivity for several beta-cell-specific autoantibodies show a different pattern of month of birth (MOB) compared with children with T1D and low beta-cell autoimmunity and that of the general population. Research design a
Effects of ozone depletion and increased ultraviolet-B radiation on northern vegetation
The stratospheric ozone layer has been depleted at high and mid-latitudes as a consequence of man's pollution of the atmosphere, and this results in increasing ultraviolet-B radiation at ground level. We investigate the effects of further radiation increases on plants and ecosystems by irradiating natural sub-Arctic and Arctic vegetation with artificial W-B radiation in field experiments extending
Deceased, disabled or depressed - a population-based 6-year follow-up study of elderly people with depression
The prognosis of depression in elderly people is reported as poor, with high mortality and high rate of non-recovery. The aim of this study was to investigate the outcome after 6 years in a broader perspective. In addition to the risk of dying, we also estimated the risk of moving to long-term care, and having a depression in a re-screening event after 6 years. In 1993, a screening event for depre
Sentinel node biopsy for breast cancer larger than 3 cm in diameter
Background: Sentinel node biopsy (SNB) is a standard staging procedure in early breast cancer. Its suitability for larger tumours has been questioned. This study evaluated the reliability of SNB in women with invasive breast cancer larger than 3 cm in diameter who were clinically axillary node negative. Methods: Some 109 women with a turnout larger than 3 cm on pathological analysis were identifie
Reinstitutionalisation in mental-health care: comparison of data on service provision from six European countries
Objective To establish whether reinstitutionalisation is occurring in mental health care mid, if so, with What variations between Western European countries. Design Comparison of data on changes in service provision. Setting Six European countries with different traditions of mental health care that have all experienced deinstitutionalisation since the 1970s - England, Germany, Italy, the Netherla

Morphological variation in Scandinavian populations of the diploid-tetraploid species pair Anthericum ramosum and Anthericum liliago (Anthericaceae)
Both members of the diploid-tetraploid species pair Anthericum ramosum L. and Anthericum liliago L. occur as geographically disjunct isolates on the margins of their northern range in Scandinavia. Variation in floral morphology was studied in 33 populations of A. ramosum from four geographic regions and 25 populations of A. liliago from seven regions in Scandinavia. Tepal shape was characterized w
Effects of grassland abandonment, restoration and management on butterflies and vascular plants
When semi-natural pastures are abandoned, specialized grassland species are lost as a consequence of succession. As a counter-measure, previously abandoned grasslands may be restored by clearing shrubs and trees and re-introducing grazing livestock. In order to examine the effects of this type of habitat restoration, we compared species richness of plants and of specialized plants thought to be de

Diet in the aetiology of ulcerative colitis: A European prospective cohort study
Background/Aims: The causes of ulcerative colitis are unknown, although it is plausible that dietary factors are involved. Case-control studies of diet and ulcerative colitis are subject to recall biases. The aim of this study was to examine the prospective relationship between the intake of nutrients and the development of ulcerative colitis in a cohort study. Methods: The study population was 26
Mate choice, male condition-dependent ornamentation and MHC in the pheasant
The Hamilton and Zuk model predicts that genes for resistance to various pathogens may be continuously heritable due to selection disequilibria caused by coadaptional cycles of hosts and pathogens. The model further suggests that the expression of male secondary ornaments is condition-dependent and that only individuals with superior genetic disease resistance and vigour can fully express exaggera
Effects of ongoing smoking on the development of radiation-induced pneumonitis in breast cancer and oesophagus cancer patients
Copper allergy from dental copper amalgam?
A 65-year-old female was investigated due to a gradually increasing greenish colour change of her plastic dental splint, which she used to prevent teeth grinding when sleeping. Furthermore, she had noted a greenish/bluish colour change on the back of her black gloves, which she used to wipe her tears away while walking outdoors. The investigation revealed that the patient had a contact allergy to
