Temperature and rainfall anomalies in Africa predict timing of spring migration in trans-Saharan migratory birds

The long-term advance in the timing of bird spring migration in the Northern Hemisphere is associated with global climate change. The extent to which changes in bird phenology reflect responses to weather conditions in the wintering or breeding areas, or during migration, however, remains to be elucidated. We analyse the relationships between the timing of spring migration of 9 species of trans-Sa

Kissing stents in the common femoral artery bifurcation for critical limb ischemia: Technical description and report of three cases

The purpose of this article is to describe three cases of kissing stent placement in the common femoral artery bifurcation in patients unsuitable for open endarterectomy and patch plasty. In three patients with critical limb ischemia, caused by primary atherosclerotic disease or dissection-related injury when performing a lower extremity intervention, a technique of kissing stents was used to trea

Comparative study of the short-term effects of a novel selective estrogen receptor modulator, ospemifene, and raloxifene and tamoxifen on rat uterus

To investigate the differential short-term effects of selective estrogen receptor (ER) modulators (SERMs) on uterus, we treated adult ovariectomized rats with a novel SERM, ospemifene (Osp), two previously established SERMs (tamoxifen and raloxifene (Ral)) and estradiol. The expression of two estrogen-regulated early response genes c-fos and vascular endothelial growth factor (VEGF), and DNA synth

OBJECTIVE: To evaluate the long-term impact on quality of life (QoL) in women referred for colposcopy after an abnormal cervical smear. STUDY DESIGN: One hundred consecutive women referred for colposcopy for the first time subsequent to receiving notification of an abnormal cervical smear. Women in the study group completed the Swedish Health Survey Short Form-36 (SF-36), the State/Trait Anxiety I

Density functional studies of solvation forces in hard sphere polymer solutions confined between adsorbing walls. I. Solvent effects and dependence on surface potential range.

Solvation forces between large surfaces in athermal polymer solutions, in which both solvent particles and polymers are adsorbed at the surfaces, are studied with density functional theory. We investigate how the range of the surface potential affects the net interaction between the surfaces. Predictions from treatments in which the solvent is explicitly induced are compared with those obtained wi

Good urodynamic practices: uroflowmetry, filling cystometry, and pressure-flow studies

This is the first report of the International Continence Society (ICS) on the development of comprehensive guidelines for Good Urodynamic Practice for the measurement, quality control, and documentation of urodynamic investigations in both clinical and research environments. This report focuses on the most common urodynamics examinations; uroflowmetry, pressure recording during filling cystometry,

Copper reduced mating behaviour in male shore crabs (Carcinus maenas (L.))

Many crustaceans use pheromones to find mates and induce mating behaviours. If pollutants impair the ability to detect chemosensory cues and respond to pheromone signals, they could profoundly affect mating. In a series of laboratory experiments, the effect of copper (0, 0.1 or 0.5 mg Cu(II) per litre for 5 days) on specific components of the mating behaviour of male shore crab Carcinus maenas was

Nödvärnsrätten - En granskning av vapenanvändning i nödvärn för enskilda och polis

Denna uppsats beskriver nödvärnsrätten och möjligheten till att använda vapen i motvåld. Genom en rättsdogmatisk metod undersöker jag nödvärnsrätten, polisers vålds- och vapenanvändning och slutligen avgöranden där enskilda och polismän agerat i nödvärn med vapen. En medborgare i en rättsstat får inte ta rätten i sina egna händer. Vid ett brottsligt angrepp har dock enskilda och polismän rätt tilThis essay describes the right to self-defense in society and the use of weapons in counter-violence in situations of self-defense. Using a legal dogmatic methodology, I investigate the right to self-defense and then study the police´s right to practice violence and use of firearms. After this I analyze different law cases where policemen and civilians acted in self-defense with a weapon. In a st

THE ROLE OF BMP SIGNALING AND ENDOGLIN IN REGULATION OF HEMATOPOIESIS

Hematopoiesis, the formation of blood cells, ultimately depends on a rare population of hematopoietic stem cells (HSCs), which can both self-renew to maintain the HSC pool, and differentiate into all mature blood lineages. HSC fate decisions are governed by a complex combination of numerous signals, although the molecular mechanisms are not fully understood. This thesis describes the role of two i

Complications to peptic ulcer and peptic ulcer surgery

Long term effects after peptic ulcer surgery still exert an influence on some patient groups. Partial gastrectomy increases the risk of gastric carcinoma more than 20 years after surgery and enterogastric reflux is regarded as the main ethiological factor. Partial gastrectomy also gives increased risk of other malignancies as well as smoking related disease. Parietal cell vagotomy (PCV) is conside

Comparing retinal function and structure in diabetic maculopathy and retinal detachment with ff-ERG and a combination of mfERG and OCT

Diabetic maculopathy and retinal detachment, especially involving macula, are potentially sight-threatening conditions. Previous evaluations of retinal function, and treatment of these conditions have been subjective methods depending on the examiner or the collaboration with the examined patient. Retinal structure has been based on the subjective evaluation of the ophthalmologist. Development of

In Vivo Reprogramming of Striatal NG2 Glia into Functional Neurons that Integrate into Local Host Circuitry.

The possibility of directly converting non-neuronal cells into neurons in situ in the brain would open therapeutic avenues aimed at repairing the brain after injury or degenerative disease. We have developed an adeno-associated virus (AAV)-based reporter system that allows selective GFP labeling of reprogrammed neurons. In this system, GFP is turned on only in reprogrammed neurons where it is stab

Assessing ozone exposure for epidemiological studies in Malmo and Umea, Sweden

Ground level ozone [ozone] is considered a harmful air pollutant but there is a knowledge gap regarding its long term health effects. The main aim of this study is to develop local Land Use Regression [LUR] models that can be used to study long term health effects of ozone. The specific aim is to develop spatial LUR models for two Swedish cities, Umea and Malmo, as well as a temporal model for Mal

Controlling Structure and Water Miscibility of Polyion - Surfactant Ion Complex Salts

Popular Abstract in Swedish Interaktionen mellan laddade polyjoner och motsatt laddade tensid joner har undersökts. Detta har gjorts genom att syntetisera det komplexa saltet (polyjon-tensid jon) och använda detta som utgångspunkt. Olika parametrar för det komplexa saltet har varierats systematiskt och effekten på struktur och vattenupptag har undersökts. Komplexa salt (CxTAPAy) bestående av alkylThe interaction between poylions and oppositely charged surfactant ions has been investigated. This has been done by using the pure complex salt (polyion + surfactant ion) as a point of departure. Different parameters of the complex salt have been varied in a systematic way and the effect on structure and water miscibility has been investigated. Complex salts (CxTAPAy) consisting of alkyl trimethy

Future stratospheric ozone depletion will affect a subarctic dwarf shrub ecosystem

Popular Abstract in Swedish Det stratosfäriska ozonlagret håller på att förtunnas och detta kommer att leda till att mer skadlig ultraviolett-B (UV-B) strålning når ner till biosfären. För att undersöka hur detta påverkar ett subarktiskt hedekosystem har vi bestrålat ett sådant med extra UV-B strålning motsvarande 15 % ozonförtunning. Studierna har utförts på en dvärgbuskhed vid Abisko NaturvetensThe stratospheric ozone depletion and the concomitant increase in ultraviolet-B (UV-B, 280-320 nm) radiation is of global concern due to the effects of UV-B on living organisms. To investigate the effects of increased levels of UV-B, a field irradiation system was established at a subarctic dwarf shrub heath in Northern Sweden (68 °N). An ozone depletion of 15 % under clear sky conditions was simu

Starting-Condition Dependence of Order Parameters Derived from Molecular Dynamics Simulations

We have studied how backbone N-H S-2 order parameters calculated from molecular dynamics simulations depend on the method used to calculate them, the starting conditions, and the length of the simulations. Using the carbohydrate binding domain of galectin-3 in the free and lactose-bound states as a test case, we compared the calculated order parameters with experimental data from NMR relaxation. T

Interannual Coupling between Summertime Surface Temperature and Precipitation over Land: Processes and Implications for Climate Change

Widespread negative correlations between summertime-mean temperatures and precipitation over land regions are a well-known feature of terrestrial climate. This behavior has generally been interpreted in the context of soil moisture atmosphere coupling, with soil moisture deficits associated with reduced rainfall leading to enhanced surface sensible heating and higher surface temperature. The prese

Analysis of carbonyl compounds in sea buckthorn for the evaluation of triglyceride oxidation, by enzymatic hydrolysis and derivatisation methodology

Carbonyl compounds formed in sea buckthorn berry (Hippophae rhamnoides) and oil samples as a result of lipid oxidation were determined by enzymatic hydrolysis followed by derivatisation with 2,4-dinitrophenylhydrazine and analysed by LC-UV and electrospray ionisation (ESI) tandem mass spectrometry (MS/MS). Several classes of carbonyl compounds such as saturated, unsaturated, linear and branched al

Education, training and skills in innovation policy

The main question that guides this paper is how governments are focusing (and must focus) on competence building (education, training and skills) when designing and implementing innovation policies. After a brief literature review, this paper suggests a typology of internal/external and individual/organizational sources of competences that are related to innovation activities. This serves to exami
