New research indicates that firms combining the science-based STI (Science, Technology, Innovation) and the experience-based DUI (Doing, Using, Interacting) modes of innovation are more efficient when it comes to improving innovation capacity and competitiveness. With regard to innovation policy, the STI mode calls for a supply-driven policy, typically aimed to commercialize research results. The

Venous thromboembolism is common in the general population with increasing age as one of the most important risk factors. The care of hemophilia and von Willebrand disease has improved in recent decades, resulting in the expectation of a growing population of aging people with these disorders. Thrombosis seems rare in hemorrhagic disorders but studies documenting the true epidemiology are virtuall

A series of nine donor-acceptor polymers, including three new and six polymers from previous work, have been investigated experimentally and theoretically. The investigation focuses on narrow band gaps and strong absorptions of the polymers, where experimentally determined first peak absorption energies range from 1.8 to 2.3 eV, and peak absorption coefficients vary between 19-67 L g(-1) cm(-1). A

The islets of Langerhans are key regulators of glucose homeostasis and have been known as a structure for almost one and a half centurys now. During the twentieth century several different cell types were described in the islets of different species and at different developmental stages. Six cell types with identified hormonal product have been described so far by the use of histochemical staining

The site-directed generation of a heterodinuclear FeIIICuII complex by using a new asymmetric dinucleating ligand FloH is reported. The iron(III) ion is introduced first on the preferential metal-binding site of the ligand that leads to the formation of the thermodynamically favored five-membered chelate rings upon metal-binding. Copper(II) is introduced in the next step. The stepwise metalation s

The European Landscape Convention indicates that assessment of different dimensions that exist in landscapes should be taken into account in planning. In this study, we first investigated ecological, cultural and social values as perceived by the local people in a highway-planning process in Sweden. Next, we explored which factors influenced the local people's participation in the road-planning pr

A study was undertaken to test the affect of chronic exposure to elevated dissolved carbon dioxide on juvenile Atlantic cod. The CO2 treatment concentrations were designated as low (1-2 mg L-1, 1000 mu atm), medium (8 mg L-1, 3500 mu atm) and high (18 mg L-1, 8500 mu atm), and the fish were reared at 10 C and 20% salinity. A marked observation at the end of the 55 day trial was that an increase in

Bats evolved the ability of powered flight more than 50 million years ago. The modern bat is an efficient flyer and recent research on bat flight has revealed many intriguing facts. By using particle image velocimetry to visualize wake vortices, both the magnitude and time-history of aerodynamic forces can be estimated. At most speeds the downstroke generates both lift and thrust, whereas the func

Exhaust gas recirculation (EGR) sweeps were performed on ethanol partially premixed combustion (PPC) to show different emission and efficiency trends as compared with diesel PPC. The sweeps showed that when the EGR rate is increased, the efficiency does not diminish, HC trace is flat, and CO is low even with 45% of EGR. NOx exponentially decreases by increasing EGR while soot levels are nearly zer

Despite a century of research into visual word recognition, basic questions remain unresolved about the functional architecture of the process that maps visual inputs from orthographic analysis onto lexical form and meaning and about the units of analysis in terms of which these processes are conducted. Here we use magnetoencephalography, supported by a masked priming behavioral study, to address

Cerebral arteries subjected to different types of experimental stroke upregulate their expression of certain G-protein-coupled vasoconstrictor receptors, a phenomenon that worsens the ischemic brain damage. Upregulation of contractile endothelin B (ETB) and 5-hydroxytryptamine 1B (5-HT1B) receptors has been demonstrated after subarachnoid hemorrhage and global ischemic stroke, but the situation is

We present preliminary evidence for a novel evolutionary hypothesis, i.e., that animals living on plants high in antimicrobial secondary metabolites could, via drift or selection, evolve weakened immune defenses and an immunological dependence on the antimicrobial properties of their plant substrate and/or the volatile mix in the air surrounding their plant. Animals experience immunological stress

In the field of developmental biology, there is compelling evidence for a network of activity of pluripotency and stem-associated genes comprising of Oct4, Nanog and nestin. During neurogenesis, the choice between enhancement versus suppression of transcriptional modulation of these identified genes determines the balance between self-renewal neural stem cells (NSC) and immature neuronal phenotype

With the expanding armamentarium of noninsulin therapies for type 2 diabetes mellitus, the use of insulin with various oral agents is becoming more common. In this study, we assessed the efficacy and cardiovascular (CV) safety of the dipeptidyl peptidase-4 inhibitor linagliptin as add-on to insulin in patients with type 2 diabetes.

Using a newly developed in vivo model measuring glucagon-like peptide-1 (GLP-1) in gut lymphatics in mice, we quantified GLP-1 secretion in vivo after glucose versus fat ingestion with and without concomitant DPP-4 inhibition. The mesenteric lymphatic duct was cannulated in anesthetized C57BL6/J mice and lymph was collected in 30min intervals. Glucose or fat emulsion (Intralipid(R)) (0.03, 0.1 or

In this paper, we report on measurements of bremsstrahlung in laser ion acceleration experiments from ultra-thin, polymer-based target foils. The influence of laser polarization on the generated radiation, the maximum achievable proton energy and the total proton number is investigated. A clear benefit in terms of radiation reduction by the use of circular polarized light can be observed. At the s

PURPOSE: preeclampsia (PE) is a severe, multi-system pregnancy disorder of yet unknown cause, missing means of treatment, and our fundamental understanding of the disease is still impaired. The purpose of this discovery study was to define candidate placenta tissue protein biomarker signatures to further decipher the molecular features of PE.EXPERIMENTAL DESIGN: we used recombinant antibody microa
