Orientation can be difficult for nocturnal bird migrants at high northern latitudes because of the large changes of magnetic declinations, rapid longitudinal time-shifts experienced during a long-distance flight and the invisibility of stars during the polar summer. Both sunset cues as well as geomagnetic cues have been shown to be of great importance in the orientation system of Savannah sparrows

Using high-throughput technologies, abundances and other features of genes and proteins have been measured on a genome-wide scale in Saccharomyces cerevisiae. In contrast, secondary structure in 5'-untranslated regions ( UTRs) of mRNA has only been investigated for a limited number of genes. Here, the aim is to study genome-wide regulatory effects of mRNA 5'-UTR folding free energies. We performed

Background: Much effort has been made to study first-ever stroke patients. However, recurrent stroke has not been investigated as extensively. It is unclear which risk factors dominate, and whether adequate secondary prevention has been provided to patients who suffer from recurrent stroke. Also, the different types of recurrent stroke need further evaluation. Methods: The study included patients

Background: Local pain at the site of intravenous (iv) injection of propofol remains a considerable problem in clinical anaesthesiology, and particularly so in infants. The aim of the present study was to compare the influence of two different emulsions of propofol on local pain following iv administration. Methods: Eighty adult patients (ASA I-II) scheduled for ear-nose-throat or plastic surgery

OBJECTIVE - This study was designed to investigate the clinical characteristics of a large type 1 diabetic population and to evaluate the degree of fulfillment of recently updated treatment goals. RESEARCH DESIGN AND METHODS - The Swedish National Diabetes Register was initiated in 1996 as a tool for quality assurance in diabetes care. A1C levels, treatment, and risk factors were analyzed in two c

The treatment of prostatic carcinoma with estrogens is associated with an increased risk of cardiovascular as well as thromboembolic complications. In the present study, patients harboring highly or moderately differentiated prostatic carcinoma without signs of metastases were treated with either polyestradiolphosphate + etinylestradiol, estramustine phosphate or given no treatment. Subsequently,

Scand J Caring Sci; 2011 Individual placement and support - a model to get employed for people with mental illness - the first Swedish report of outcomes Lack of participation in the open labour market is highly prevalent for people with a mental illness across countries, and the proportion of people who get some kind of sickness benefit because of mental illness is steadily growing in Europe. Voc

Galiellalactone is a potent and specific inhibitor of STAT3 signaling which has been shown to possess growth inhibitory effects on prostate cancer cells expressing active STAT3. In this study we aimed to investigate the effect of galiellalactone on prostate cancer stem cell-like cells. We explored the expression of aldehyde dehydrogenase (ALDH) as a marker for cancer stem cell-like cells in differ

Trees growing at their altitudinal or latitudinal distribution in Fennoscandia have been widelyused to reconstruct warm season temperatures, and the region hosts some of the world’slongest tree-ring chronologies. These multi-millennial long chronologies have mainly beenbuilt from tree remains found in lakes (subfossil wood from lake-shore trees). We used aunique dataset of Scots pine tree-ring dat

Background: The knowledge about air pollution effects on birth weight, prematurity and small for gestational age [SGA] in low-exposure areas is insufficient. Objectives: The aim of this birth cohort study was to investigate if low-level exposure to air pollution was associated with prematurity and foetal growth and if there are gender specific effects. Method: We combined high quality registry inf

The aim of this study was to investigate if costimulation blockade could be used to modulate the immune response, to prevent rejection, and to stimulate regeneration into nerve allografts. Nerve allografts from Balb/C mice, and isogenic nerve grafts (isografts) from C57/BL6 mice, were used to bridge a 7-mm gap of the sciatic nerve in C57/BL6 mice. Allograft recipients were treated with either a tr

A cross-sectional study was conducted to assess the extent of unstructured HIV treatment interruptions (TIs) and investigate the effects of socioeconomic, socio-demographic, HIV treatment-related and clinical factors on the magnitude and rate of the same among adult patients at a Kenyan regional referral center. Four hundred and twenty-one adult patients actively receiving antiretroviral therapy a

INTRODUCTION: Hyperactivity of the hypothalamic-pituitary-adrenal (HPA)-axis is a common finding in major depressive disorder. Similar studies on suicide attempters are less abundant, and the results are divergent. The main aim of the present study was to investigate HPA-axis parameters by the time of a suicide attempt and at follow-up in search for associations between HPA-axis function and suici

BACKGROUND:: Epidemiological reports on risk and prognostic factors in patients with mesenteric venous thrombosis (MVT) are scarce. METHODS:: Patients with MVT were identified through the inpatient and autopsy registry between 2000 and 2006 at Malmö University Hospital. RESULTS:: Fifty-one patients had MVT, diagnosed at autopsy in six. The highest incidence (11.3 per 100 000 person-years) was in t

Single-nucleotide polymorphisms (SNPs) in the major histocompatibility complex class II transactivator (MHC2TA) gene encoding the class II transactivator have been associated with multiple sclerosis, rheumatoid arthritis, and myocardial infarction in the Swedish population. We used a case-control approach to investigate the prevalence of a relevant variant in Swedish systemic lupus erythematosus (

Chronic lymphocytic leukemia (CLL) is a clinically heterogeneous disease with no known single predisposing genetic factor shown in all cases. Recently, a single nucleotide polymorphism (SNP) T393C in the GNAS1 gene has been reported to have a clinical impact on CLL progression and overall survival. In order to further investigate the T393C SNP in CLL, we have genotyped 279 CLL cases and correlated

Heparin is widely used as an antithrombotic agent, but one reported complication is thrombocytopenia associated with platelet aggregation. The mechanism is not fully clear but heparin interference in the prostaglandin production has been proposed. To investigate if heparin interacts with the production of prostacyclin from the vessel wall, and if low-molecular-weight heparin differs from unfractio
