The acrotretide Acrotreta socialis von Seebach, 1865 has suffered a long and tumultuous history since its original description from the middle Cambrian (Guzhangian Stage) Andrarum Limestone of Bornholm, Denmark. Uncertainties regarding key morphological characters have resulted in numerous revisions and redescriptions of the species with much of the taxonomic shuffling occurring before the mid-20(
The mechanism behind the adjuvant effect of aluminum salts is poorly understood notwithstanding that aluminum salts have been used for decades in clinical vaccines. In an aqueous environment and at a nearly neutral pH, the aluminum salts form particulate aggregates, and one plausible explanation of the lack of information regarding the mechanisms could be the absence of an efficient method of trac
Background: This study was performed to explore whether or not a neural reflex linking the esophagus and the nasal airway exists, as a pathogenic mechanism accounting for the association between gastroesophageal reflux (GER) disease and chronic rhinosinusitis (CRS). A prospective trial of healthy human volunteers was performed. Methods: Ten healthy volunteers without GER or sinonasal disease were
Associative aqueous mixtures over a range of concentrations of double- (ds) or single- (ss) stranded DNA with dilute or semidilute solutions of two cationic derivatives of hydroxyethyl cellulose (cat-HEC and cat-HMHEC,(1) the latter carrying grafted hydrophobic groups), were studied. The phase behavior showed an interesting asymmetry: Phase separation occurred immediately when small (sub-stoichiom
Abstract Aims: The Satisfaction with Daily Occupations (SDO) scale assesses satisfaction within the domains of work, leisure, domestic tasks, and self-care. The aim was to investigate the psychometric properties of the Danish version of the SDO when used with asylum seekers. Methods: The participants were 93 Danes without known ill health and 43 asylum seekers. They completed the SDO and rated the
Abstract In plasma-assisted combustion, electric energy is added to the flame where the electric energy will be transferred to kinetic energy of the free electrons that, in turn, will modify the combustion chemical kinetics. In order to increase the understanding of this complex process, the influence of one of the products of the altered chemical kinetics, ozone (O3), has been isolated and studie
Phenological changes are well documented biological effects of current climate change but their adaptive value and demographic consequences are poorly known. Game theoretical models have shown that deviating from the fitness-maximising phenology can be evolutionary stable under frequency-dependent selection. We study eco-evolutionary responses to climate change when the historical phenology is mis
Arterial stiffness has been hypothesized to contribute to cognitive decline. However, previous studies have reported inconsistent results. The aim of this cross-sectional study was to investigate the association between carotid-femoral pulse wave velocity (cfPWV), a marker of arterial stiffness, and cognitive function.
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
AIMS: To investigate the associations between economic stress in childhood and adulthood, and tobacco smoking, with reference to the accumulation, critical period and social mobility hypotheses from life-course epidemiology. DESIGN/SETTING/PARTICIPANTS/MEASUREMENTS: The 2008 public health survey in Skåne, Sweden is a cross-sectional postal questionnaire study based on a random sample which yielded
Diabetes mellitus is a lifelong, incapacitating disease affecting multiple organs. Presently, type 2 diabetes (T2D) can neither be prevented nor cured and the disease is associated with devastating chronic complications. These complications impose an immense burden on the quality of life of patients and account for about 12% of direct health care costs in Europe. Genetic analysis will increase our
The ability of particles to activate and form cloud droplets influences the functioning of the Earth's hydrological cycle. This work links the particle water uptake at subsaturation to the critical supersaturation ratio needed for particles to become cloud condensation nuclei (CCN). Five models using the particle hygroscopic growth at subsaturation for predicting the critical supersaturation neede
In order to investigate molecular events involved in the regulation of lymphoid lineage commitment, we crossed lambda5 reporter transgenic mice to Rag1-GFP knock in mice. This allowed us to sub-fractionate common lymphoid progenitors (CLPs) and pre-pro-B (Fraction A) cells into lambda5(-)Rag1(low), lambda5(-)Rag1(high) and lambda5(+)Rag1(high) cells. Clonal in vitro differentiation analysis demons
Background: Gene-virus targeted therapy is a promising new method of treating pancreatic cancer. To increase the efficacy and decrease the side-effect, we constructed a conditionally replicative adenovirus (CRAd) expressing human endostatin, with a human Telomoerase Reverse Transcriptase (hTERT) promoter for the regulation of the early stage of adenovirus expression of gene E1a and a Hypoxia Respo
Postoperative pain may lead to delayed mobilization, persisting pain, and psychosocial distress. There are no simple and reliable techniques for prediction of postoperative pain. This study was designed to evaluate if pain induced by venous cannulation or propofol injection can be used to predict postoperative pain.
Aim Our aim was to define the dynamics in collagen concentrations in the large bowel wall following decompression of experimental obstruction. Method Colonic obstruction was created in 28 male rats by the placement of a silicone ring around the distal colon. The ring was removed after 4 days to mimic endoscopical decompression by stent deployment. Colon circumference and collagen concentration wer
Twin studies have shown that criminal behavior (CB) is influenced by both genetic and shared environmental factors. Could these results be replicated using full-siblings and half-siblings?
