Evolutionary molecular studies of island radiations may lead to insights in the role of vicariance, founder events, population size and drift in the processes of population differentiation. We evaluate the degree of population genetic differentiation and fixation of the Canary Islands blue tit subspecies complex using microsatellite markers and aim to get insights in the population history using c

We report whole-rock elemental and Sm-Nd isotope geochemical data from mafic-ultramafic supracrustal rocks from the Nunatak 1390 area in southern West Greenland. Additionally, we report the metamorphic temperature history for these rocks as derived from tourmaline thermometry on a tourmalinite inlier, as well as in situ U-Pb, Hf and O isotopic data from zircons extracted from tonalite-trondhjemite

Bark beetle population dynamics is thought to be primarily driven by bottom-up forces affecting insect performance and host tree resistance. Although there are theoretical predictions and empirical evidences that predation and parasitism may play an important role in driving bark beetle population fluctuations, long-term studies testing the role of both biotic and abiotic controls on population dy

The COX2 rs5277 (306G>C) polymorphism has been associated with inflammation-associated cancers. In breast cancer, tumor COX-2 expression has been associated with increased estrogen levels in estrogen receptor (ER)-positive and activated Akt-pathway in ER-negative tumors. Our study investigated the impact of COX2 genotypes on early breast cancer events and treatment response in relation to tumor ER

The natural history and physiological determinants of glucose intolerance in subjects living in Europe have not been investigated. The aim of this study was to increase our understanding of this area. We analysed the data from a population-based cohort of 1,048 non-diabetic, normotensive men and women (aged 30-60 years) in whom insulin sensitivity was measured by the glucose clamp technique (M/I i

Recently a considerable amount of effort has been put into quantifying how interactions of the carbon and nitrogen cycle affect future terrestrial carbon sinks. Dynamic vegetation models, representing the nitrogen cycle with varying degree of complexity, have shown diverging constraints of nitrogen dynamics on future carbon sequestration. In this study, we use LPJ-GUESS, a dynamic vegetation model

Environmental conditions and human activities play a significant role in structuring novel assemblages of native and non-native species. Ongoing and future climatic change may alter the performance of native and non-native species and their biotic interactions. In the northern hemisphere, expected climate changes include warmer temperatures and higher precipitation, the latter of which may increas

OBJECTIVE: The Swedish Early Psoriatic Arthritis Register describes the course of early psoriatic arthritis (PsA) in a real life clinical setting in Sweden. The aim of this study was to obtain information on predictors of clinical outcomes over a 5-year period with special focus on effects of gender, joint patterns, diagnostic delay and initial disease activity. METHODS: In six centres, patients w

Surgery is essential for global cancer care in all resource settings. Of the 15.2 million new cases of cancer in 2015, over 80% of cases will need surgery, some several times. By 2030, we estimate that annually 45 million surgical procedures will be needed worldwide. Yet, less than 25% of patients with cancer worldwide actually get safe, aff ordable, or timely surgery. This Commission on global ca

Magnetotactic bacteria (MTB) are known to biosynthesise single-domain magnetite (Fe3O4) for geomagnetic navigation and their relict magnetosomes (called magnetofossils) can control the magnetic properties of lake and marine sediments. Magnetotactic bacteria also produce greigite (Fe3S4) magnetosomes but, compared to those made of magnetite, relatively little is known about the sedimentary environm

Soil temperature (Ts) change is a key indicator of the dynamics of permafrost. On seasonal and interannual timescales, the variability of Ts determines the active-layer depth, which regulates hydrological soil properties and biogeochemical processes. On the multi-decadal scale, increasing Ts not only drives permafrost thaw/retreat but can also trigger and accelerate the decomposition of soil organ

BACKGROUND: Patients with inflammatory joint diseases tend due to new treatments to be more physically active; something not taken into account by currently used outcome measures. The Rheumatoid and Arthritis Outcome Score (RAOS) is an adaptation of the Knee injury and Osteoarthritis Outcome Score (KOOS) and evaluates functional limitations of importance to physically active people with inflammato

The work presented in this thesis aims at improving spectroscopic techniques for analysis of pharmaceutical solids. This improvement is achieved by the combining and development of instrumentations and data evaluation tools from two research fields: the fields of near infrared spectroscopy and biomedical optics. The thesis include the construction and evaluation of different variable selection te

In the 1990s a contraction in state welfare in Sweden has been on its way and still seems to be so by joining forces. With focus on understanding the dynamics involved in the contractionprocess this paper aims to discuss the transition of welfare state commitment in Sweden. On the general level it should be seen as an attempt to adress the enigmatic and puzzeling questions of: How to explain chang

Anthropogenic radionuclide concentrations have been determined in seawater and sediment samples collected in 1991, 1994 and 1996 in the Eurasian Arctic shelf and interior. Global fallout, releases from European reprocessing plants and the Chernobyl accident are identified as the three main sources. From measurements in the Eurasian shelf seas it is concluded that the total input of Cs-134, Cs-137

Partial lesions of the nigrostriatal dopamine system have been investigated with respect to their ability to induce consistent long-lasting deficits in movement initiation and skilled forelimb use. In eight different lesion groups 6-hydroxydopamine (6-OHDA) was injected at one, two, three, or four sites into the lateral sector of the right striatum, in a total dose of 20-30 microgram. Impairments

Background: Among patients with ST-elevation acute myocardial infarction, those with terminal QRS distortion (grade 3 ischemia) have higher mortality and larger infarct size (IS) than patients without QRS distortion (grade 2 ischemia). Methods: We assessed the relation of baseline electrocardiographic ischemia grades to area at risk (AR) and myocardial salvage [100 (AR - IS)/AR] in 79 patients who

The success of the IEEE 802.11 standard has prompted research into efficiency of the different medium access methods and their support for different traffic types. A modified version of the point coordination function (PCF) called modified PCF has been introduced as a way to improve the efficiency over the standard method. It has been shown through a simulation study and a mathematical analysis th

This thesis is an exploratory, descriptive and comparative study of teachers’ focus and teaching methods in Spanish as a third language (L3) in Sweden. The curriculum of Modern Languages emphasizes communicative competence and the purpose of the study is to examine how this is applied in the teaching of the course Spanish 4 and how the students progress during the course. Five teachers at four Sen
