MESENCHYMAL STEM- AND STROMAL CELLS IN BONE MARROW AND OSTEOSARCOMA

Popular Abstract in Swedish Mesenkymala stamceller (MSC) kan isoleras från en rad olika vävnader i kroppen, bland annat från benmärg. De kan differentiera till ben, brosk, fett- och bindvävnad men deras exakt roll i kroppen är inte väl känd. Den senaste forskningen tyder dock på att en av deras huvuduppgifter är att stödja blodbildningen som sker av blod- eller hematopoetiska stamceller. Man Primary mesenchymal stem cells (MSC) play a central role in bone marrow (BM) and during haematopoiesis. Yet, the exact phenotype and spatial distribution of primary MSC in the human BM are unknown. Their cultured progeny are promising candidates for clinical applications. MSC cultures however, are heterogeneous and, while critical for clinical applications, their exact composition is not known. W

Pooled Panel Unit Root Tests and the Effect of Past Initialization

This paper analyzes the role of initialization when testing for a unit root in panel data, an issue that has received surprisingly little attention in the literature. In fact, most studies assume that the initial value is either zero or bounded. As a response to this, the current paper considers a model in which the initialization is in the past, which is shown to have several distinctive features

Laser absorption spectroscopy of water vapor confined in nanoporous alumina: wall collision line broadening and gas diffusion dynamics.

We demonstrate high-resolution tunable diode laser absorption spectroscopy (TDLAS) of water vapor confined in nanoporous alumina. Strong multiple light scattering results in long photon pathlengths (1 m through a 6 mm sample). We report on strong line broadening due to frequent wall collisions (gas-surface interactions). For the water vapor line at 935.685 nm, the HWHM of confined molecules are ab

Bio-based 3-hydroxypropionic- and acrylic acid production from biodiesel glycerol via integrated microbial and chemical catalysis

Background 3-Hydroxypropionic acid (3HP) and acrylic acid (AA) are industrially important platform- and secondary chemical, respectively. Their production from renewable resources by environment-friendly processes is desirable. In the present study, both chemicals were almost quantitatively produced from biodiesel-derived glycerol by an integrated process involving microbial and chemical catalysis

Catenarina (Teloschistaceae, Ascomycota), a new Southern Hemisphere genus with 7-chlorocatenarin

A new genus, Catenarina (Teloschistaceae, Ascomycota), with three species is described from the Southern Hemisphere, supported by molecular data. All species contain the secondary metabolite 7-chlorocatenarin, previously unknown in lichens. Catenarinadesolata is a non-littoral, lichenicolous species found on volcanic and soft sedimentary rock at 190-300 m in and near steppes in southernmost Chile

Analytical prediction of package collapse - consideration of windows in the package

Windows in a package is a common way to promote the product. The possibility to predict the collapse load for these types of cartonboard packages is considered. It is shown that reliable estimates of the collapse loads can be obtained by a very simple approach. This approach is a straightforward generalization of the proposal by Ristinmaa et al. (2012): for a side that contains a window, one simpl

Missiological developments from Edinburgh 1910 to Today

Critical evaluation of the World Missionary Conference, Edinburgh 1910, from the perspective of later 20th century developments in Christian mission and ecumenism, with special attention to the global South and postcolonial analysis.

Time Scales of Conformational Gating in a Lipid-Binding Protein

Lipid-binding proteins Sequester amphiphilic molecules in a large internal : cavity occupied by similar to 30 water molecules, some of which are displaced by the ligand. The role; of these internal water molecules in lipid binding and release is not understood. We use magnetic relaxation dispersion (MRD) to directly monitor internal-water dynamics in apo and palmitate-bound rat intestinal fatty ac

Mothers' representations of caregiving and their adult children's representations of attachment: Intergenerational concordance and relations to beliefs about mothering.

Mothers (N= 35) and their adult children completed questionnaires and were interviewed in order to examine relationships between mothers' caregiving representations and their adult children's attachment representations, and relationships between attachment/caregiving representations and beliefs about mothering. Mothers' and their children's accounts of and present thinking about their past relatio

Investigation on elemental mercury oxidation mechanism by non-thermal plasma treatment

Converting elemental mercury into divalent compound is one of the most important steps for mercury abatement from coal fired flue gas. The oxidation of elemental mercury was investigated in this paper using dielectric barrier discharge (DBD) non-thermal plasma (NTP) technology at room temperature. Effects of different flue gas components like oxygen, moisture, HCl, NO and SO2 were investigated. Re

Utilization of prey-rich patches leads to reproductive advantages for clustered individuals of a web-building spider

The ideal free distribution (IFD) model predicts that consumers match the distribution of resources across habitat patches and that this association should lead to equal individual fitness among individuals in a population. Here we studied to what extent predators utilize different prey groups and if the resulting spatial patterns relate to the reproductive success of individuals in a population o

On the reliability of powder diffraction Line Profile Analysis of plastically deformed nanocrystalline systems.

An iron-molybdenum alloy powder was extensively deformed by high energy milling, so to refine the bcc iron domain size to nanometer scale (~10 nm) and introduce a strong inhomogeneous strain. Both features contribute to comparable degree to the diffraction peak profile broadening, so that size and strain contributions can be easily separated by exploiting their different dependence on the diffract

Towards Quantitative Optical Cross Sections in Entomological Laser Radar - Potential of Temporal and Spherical Parameterizations for Identifying Atmospheric Fauna.

In recent years, the field of remote sensing of birds and insects in the atmosphere (the aerial fauna) has advanced considerably, and modern electro-optic methods now allow the assessment of the abundance and fluxes of pests and beneficials on a landscape scale. These techniques have the potential to significantly increase our understanding of, and ability to quantify and manage, the ecological en

A Correlation Analysis of the Roles of Soot Formation and Oxidation in a Heavy-Duty Diesel Engine

Emissions and in-cylinder pressure traces are used to compare the relative importance of soot formation and soot oxidation in a heavy-duty diesel engine. The equivalence ratio at the lift-off length is estimated with an empirical correlation and an idealized model of diesel spray. No correlation is found between the equivalence ratio at lift-off and the soot emissions. This confirms that trends in
