Background: Early hospital arrival and rapid intervention for acute myocardial infarction is essential for a successful outcome. Several studies have been unable to identify explanatory factors that slowed decision time. The present study examines whether personality, psychosocial factors, and coping strategies might explain differences in time delay from onset of symptoms of acute myocardial infa

Tree phenology has been recognized as an important indicator of climate change, and a wide range of budburst models have been developed. The models differ in temperature sensitivity, and the choice of model can therefore influence the result of climate impact assessments. In this study we compared the ability of 15 models to simulate budburst of the main forest tree species in Sweden. Records on t

Protein S deficiency is a dominantly inherited disorder that results from mutations in the PROS] gene. Previous sequencing of the gene failed to detect mutations in eight out of 18 investigated Swedish families, whereas segregation analyses detected large deletions in three out of the eight families. The present study investigates more thoroughly for the presence of deletions but also for other ty

This article introduces a continuous, gas-phase method for depositing thin metallic coatings onto (nano)particles using a type of physical vapor deposition (PVD) at ambient pressure and temperature. An aerosol of core particles is mixed with a metal vapor cloud formed by spark ablation by passing the aerosol through the spark zone using a hollow electrode configuration. The mixing process rapidly

Because population size is sensitive to changes in adult survival, adult survival may be buffered against environmental variability. Philopatry may be adaptive in changing environments, but it could also constrain breeding habitat selection under changing conditions such as shifting predation regimes. Habitat preference and quality could become decoupled in long-lived philopatric species that evol

Moths generally rely on pheromone communication for mate finding. The pheromone components of most moths are produced by a common pathway of fatty-acid biosynthesis coupled with species-specific modifications of the final products. Some genes involved in moth pheromone production have previously been described, whereas others remain to be characterized and thus the molecular mechanisms accounting

Deoxyribonucleoside kinases catalyze the rate limiting step during the salvage of deoxyribonucleosides and convert them into the corresponding monophosphate compounds. We have identified and characterized a unique multisubstrate deoxyribonucleoside kinase from plants. The phylogenetic relationship and biochemical properties suggest that this deoxyribonucleoside kinase represents a living fossil re

We herein report the reversible formation of a planar lamellar phase as an intermediate structure in a vesicle-micelle transition induced by temperature, for a salt-free catanionic surfactant-water system. Turbidity, small-angle neutron scattering, dynamic light scattering and microscopy data altogether demonstrate that the vesicles formed by hexadecyltrimethylammonium octylsulfonate (TA(16)So(8))

High-density lipoprotein (HDL) has anti-atherogenic properties and the plasma level of HDL cholesterol correlates inversely with the risk of coronary artery disease. The atheroprotective functions of HDL can be explained by its function in the reverse cholesterol transport. Blood coagulation is activated in response to tissue damage and involves a series of enzymatic protein complexes that assembl

We evaluated the relation between serum FGF23 and bone mineral density (BMD) in a community-based cohort of elderly men. There was a weak correlation between FGF23 and BMD, which was primarily dependent on body weight. FGF23 is a hormonal factor produced in bone and regulates serum levels of phosphate (Pi) and vitamin D. FGF23 over-expression is associated with skeletal abnormalities, including ri
