Pericytes secrete pro-regenerative molecules in response to platelet-derived growth factor-BB
Brain pericytes not only maintain the anatomical, biochemical and immune blood-brain barrier, but display features of mesenchymal stem cells (MSCs) in vitro. MSCs have pro-regenerative properties attributed to their secretome. However, whether also brain pericytes possess such pro-regenerative capacities is largely unknown. Here we characterize the secretome and microvesicle (MV) release of human

Exploring health navigating design: momentary contentment in a cancer context
Purpose: The technocratic and medicalized model of healthcare is rarely optimal for patients. By connecting two different studies we explore the possibilities of increasing quality of life in cancer care.Methods: The first study captures survival strategies in a historically isolated Arctic village in Norway resulting in Momentary contentment theory, which emerged from analysing four years of part

Recalcitrant carbon components in glomalin-related soil protein facilitate soil organic carbon preservation in tropical forests
Glomalin-related soil protein (GRSP) is known as an important microbial by-product which is crucial for preserving or accumulating soil organic carbon (SOC). However, the underlying mechanisms are not well understood. In this study, we investigated the chemical structures of GRSP and its relationship with SOC using 13C nuclear magnetic resonance (NMR) in three tropical forests. The three forests,

Robust Stochastic Performance Optimization
The problem of finding the controller that optimizes the expected H2-norm of an uncertain system is solved in closed form for a class of problems including such signal processing applications as feedforward design, channel equalization, noise cancellation etc. The method uses covariance information on model uncertainty and does therefore match information obtainable from standard system identifica
Nanoscale X-ray investigation of magnetic metallofullerene peapods
Endohedral lanthanide ions packed inside carbon nanotubes (CNTs) in a one-dimensional assembly have been studied with a combination of high resolution transmission electron microscopy (HRTEM), scanning transmission X-ray microscopy (STXM), and X-ray magnetic circular dichroism (XMCD). By correlating HRTEM and STXM images we show that structures down to 30 nm are resolved with chemical contrast and
Preparation of Decellularized Lung Matrices for Cell Culture and Protein Analysis
The limited available treatment options for patients with chronic lung diseases, such as fibrosis, lead to poor prognosis after diagnosis and short survival rates. An exciting new bioengineering approach utilizes de- and recellularization of lung tissue to potentially overcome donor organ shortage and immune reactions toward the received transplant. The goal of decellularization is to create a sca
Identification of a novel DNase of Streptococcus suis (EndAsuis) important for neutrophil extracellular trap degradation during exponential growth
The porcine and human pathogen Streptococcus suis induces and degrades neutrophil extracellular traps (NETs) in vitro. In this study, we investigated the working hypothesis that NET degradation is mediated not only by the known secreted S. suis nuclease A (SsnA) but also by a so-far undescribed putative endonuclease A of S. suis (designated EndAsuis) homologous to the pneumococcal endonuclease A (
Managing Project complexity - a managerial view
In this paper we are investigating how project complexity is affecting the management of single projects in a multi-project environment. The project manager’s perspective is applied. A conceptual framework is developed in order to summarize how project complexity effect project management. The framework is applied to two cases and conclusions are drawn.
Location, location &size : Defects close to surfaces dominate fatigue crack initiation
Metallic cast components inevitably contain defects such as shrinkage cavities which are inherent to the solidification process. Those defects are known to significantly alter the fatigue life of components. Yet very little is known, quantitatively, on the dangerosity of internal casting defects compared to surface ones. In this study, fatigue specimens containing controlled internal defects (shri

Deformation behavior of sintered nanocrystalline silver layers
Abstract The microstructure of porous silver layers produced under different low temperature pressure-assisted sintering conditions is characterized and linked with the mechanical behavior studied insitu during X-ray diffraction. Peak profile analysis reveals important strain recovery and hardening mechanism during cyclic deformation. The competition between both mechanisms is discussed in terms o
Halo suppression in full-field x-ray Zernike phase contrast microscopy
Visible light Zernike phase contrast (ZPC) microscopy is a well established method for imaging weakly absorbing samples. The method is also used with hard x-ray photon energies for structural evaluation of material science and biological applications. However, the method suffers from artifacts that are inherent for the Zernike image formation. In this Letter, we investigate their origin and experi
Knowledge for Synchronized Dual-Arm Robot Programming
We present our successful efforts to improve intuitive programming of synchronized dual-arm operations in industrialrobotic assembly tasks. To this end we extend an earlier proposed skill representation (based on our work with ontologies for industrial robots) and our respective programminginterface to integrate options for the specification, adaptationand refinement of synchronization points, syn
Bank secrecy in offshore centres and capital flows : Does blacklisting matter?
This study analyses cross-border capital flows in order to verify the existence and direction of the effect of the soft regulation promoted by international organizations against banking secrecy which characterized the so called tax and financial heavens. This effect is called in the literature Stigma Effect, but both the existence and the direction of the stigma effect are far from being obvious.
Self-esteem discrepancies and identity-expressive consumption : Evidence from Norwegian adolescents
Prior research established that simultaneously holding discrepant explicit (deliberate, controlled) and implicit (automatic, uncontrolled) self-esteem gives rise to self-enhancing behaviours. Given that individuals tend to enhance their self-concepts with brands that are associated with positive identities, this study examined whether self-esteem discrepancy was related to the extent to which indi
