We investigated whether IL1RN alleles separately or in combination with MHC class II variants, contribute to susceptibility to SLE and to analysed if IL1RN alleles are markers of disease severity. We investigated 81 patients from a defined area in southern Sweden diagnosed between 1981-1992 and 10 consecutive Caucasian families with multiple cases of SLE. As control group 189 healthy blood donors
Background The aim of this study was to investigate the influence of contextual (social capital and administrative/neo-materialist) and individual factors on lack of access to a regular doctor. Methods The 2000 public health survey in Scania is a cross-sectional study. A total of 13,715 persons answered a postal questionnaire, which is 59% of the random sample. A multilevel logistic regression
Objective. To investigate the relative importance of shared etiologies for rheumatoid arthritis (RA) and ischemic heart disease (IHD) in terms of the well-known increased risk of HID in patients with RA, by assessing the occurrence of IHD up until the time of the onset of the first symptoms of RA. Methods. We assessed the prevalence of a history of IHD, myocardial infarction (MI), and angina pecto
Colour vision models require measurement of receptor noise and the absorbance of visual pigments, oil droplets, and ocular media. We have studied how variation in these parameters influences colour matching, spectral sensitivity, and colour discrimination predictions in four bird species. While colour match predictions are sensitive to variation in visual pigment and oil droplet absorbance data, d
Background Bronchial hyperresponsiveness (BHR) is common in bakery workers. The relation between bronchial responsiveness measured with a tidal breathing method and smoking, airway symptoms, IgE-sensitization, nasal indices of inflammation and flour dust exposure have been studied with bronchial responsiveness expressed as a continuous outcome. Material and methods Bakery workers (n = 197) were su
Brent geese were tracked by satellite telemetry from spring staging areas in Denmark to Arctic breeding areas in Svalbard and Greenland in 1997 and 2001. From estimated departure masses and carcass analysis we used flight mechnical theory to estimate maximum flight ranges of both sexes, and remaining stores of fat and protein upon arrival in females. Model predictions suggested that all birds but
Radio-controlled model planes are useful when carrying out photography, especially from low altitudes, and meteorological soundings (air temperatures in boundary layers). Soundings were carried out with a system which stored the measured data on board the plane pending evaluation after the flight. The payload of the plane was a camera and equipment for measuring temperature and air pressure (altit
BACKGROUND: Ion channel transient receptor potential A1 (TRPA1) and cannabinoid (CB) receptors are involved in mechanoafferent signaling from the bladder and the urethra. OBJECTIVE: To characterize TRPA1-, CB1-, and CB2-receptor activities in the human prostate. DESIGN, SETTING, AND PARTICIPANTS: Prostate specimens were obtained from 12 patients undergoing radical prostatectomy. We studied express
Global environmental change and increasing human population emphasize the urgent need for higher yielding and better adapted crop plants. One strategy to achieve this aim is to exploit the wealth of so called landraces of crop species, representing diverse traditional domesticated populations of locally adapted genotypes. In this study, we investigated a comprehensive set of 1485 spring barley lan
