NK cell development and function - Plasticity and redundancy unleashed.

Bone marrow-derived natural killer (NK) cells constitute the major subset of cytotoxic lymphocytes in peripheral blood. They provide innate defense against intracellular infection or malignancy and contribute to immune homeostasis. Large numbers of NK cells are also present in tissues, including the liver and uterus, where they can mediate immunosurveillance but also play important roles in tissue

Plasma S100A8/A9 Correlates With Blood Neutrophil Counts, Traditional Risk Factors, and Cardiovascular Disease in Middle-Aged Healthy Individuals.

The S100 alarmins A8, A9, and A8/A9, secreted by activated neutrophils and monocytes/macrophages, are involved in the pathogenesis of various inflammatory diseases. S100A8/A9 has previously been linked to atherogenesis and cardiovascular (CV) disease. We investigated whether S100A8, A9, and A8/A9 correlate with carotid artery disease and CV risk in apparently healthy individuals.

Experimental study of pressure drop and heat transfer in a U bend channel with various guide vanes and ribs

An experimental study was conducted to investigate pressure drop and heat transfer in a U-bend section with various configurations of guide vanes and two kinds of rib shapes on the outer wall. Ten guide vane types were tested. Results highlight that the use of special guide vanes can reduce the pressure drop penalty up to a maximum of 31%. However, guide vanes are usually associated with heat tran

Communication of Corporate Social Responsibility: A Study of the Views of Management Teams in Large Companies

In light of the many corporate scandals, social and ethical commitment of society has increased considerably, which puts pressure on companies to communicate information related to corporate social responsibility (CSR). The reasons underlying the decision by management teams to engage in ethical communication are scarcely focussed on. Thus, grounded on legitimacy and stakeholder theory, this study

Development and characterization of a multiple-coincidence ion-momentum imaging spectrometer.

The design and performance of a high-resolution momentum-imaging spectrometer for ions which is optimized for experiments using synchrotron radiation is presented. High collection efficiency is achieved by a focusing electrostatic lens; a long drift tube improves mass resolution and a position-sensitive detector enables measurement of the transverse momentum of ions. The optimisation of the lens f

Genomewide Association Study Using a High-Density Single Nucleotide Polymorphism Array and Case-Control Design Identifies a Novel Essential Hypertension Susceptibility Locus in the Promoter Region of Endothelial NO Synthase.

Essential hypertension is a multifactorial disorder and is the main risk factor for renal and cardiovascular complications. The research on the genetics of hypertension has been frustrated by the small predictive value of the discovered genetic variants. The HYPERGENES Project investigated associations between genetic variants and essential hypertension pursuing a 2-stage study by recruiting cases

Strategies for inhibitor treatment and costs in the short and long term: a critical evaluation of recent clinical studies

One important complication of patients with severe haemophilia A is the formation of inhibitory antibodies to factor VIII (FVIII). Immune tolerance induction (ITI) is the treatment of choice for patients with inhibitors, but this approach is successful in about 60% of patients. Treatment of acute bleeding in patients with inhibitors is one of the greatest challenges in haemophilia management and i

Editorial

This special section of Genes and Nutrition presents a baseline analysis of ethical and legal issues undertaken within the EU FP7 research project Food4Me, which investigates the feasibility today of the vision for delivering personalized nutrition. Four major topics are addressed: Do we know enough for offering personalized nutritional advice? How can personal, cultural, and scientific perspectiv

Designing pi-stacked molecular structures to control heat transport through molecular junctions

We propose and analyze a way of using pi stacking to design molecular junctions that either enhance or suppress a phononic heat current, but at the same time remain conductors for an electric current. Such functionality is highly desirable in thermoelectric energy converters, as well as in other electronic components where heat dissipation should be minimized or maximized. We suggest a molecular d

Chemical Evolution of the Inner 2 Degrees of the Milky Way Bulge: [α/Fe] Trends and Metallicity Gradients

The structure, formation, and evolution of the Milky Way bulge is a matter of debate. Important diagnostics for discriminating between models of bulge formation and evolution include alpha-abundance trends with metallicity, and spatial abundance and metallicity gradients. Due to the severe optical extinction in the inner Bulge region, only a few detailed investigations of this region have been per

Fibroblast growth factor 10 represses premature cell differentiation during establishment of the intestinal progenitor niche

Spatio-temporal regulation of the balance between cell renewal and cell differentiation is of vital importance for embryonic development and adult homeostasis. Fibroblast growth factor signaling relayed from the mesenchyme to the epithelium is necessary for progenitor maintenance during organogenesis of most endoderm-derived organs, but it is still ambiguous whether the signal is exclusively mitog

Group Formation, Relatedness, and the Evolution of Multicellularity

The evolution of multicellular organisms represents one of approximately eight major evolutionary transitions that have occurred on earth [1-4]. The major challenge raised by this transition is to explain why single cells should join together and become mutually dependent, in a way that leads to a more complex multicellular life form that can only replicate as a whole. It has been argued that a hi

GIRK2 Expression in Dopamine Neurons of the Substantia Nigra and Ventral Tegmental Area

G-protein-regulated inward-rectifier potassium channel 2 (GIRK2) is reported to be expressed only within certain dopamine neurons of the substantia nigra (SN), although very limited data are available in humans. We examined the localization of GIRK2 in the SN and adjacent ventral tegmental area (VTA) of humans and mice by using either neuromelanin pigment or immunolabeling with tyrosine hydroxylas

An ecosystem-scale perspective of the net land methanol flux : synthesis of micrometeorological flux measurements

Methanol is the second most abundant volatile organic compound in the troposphere and plays a significant role in atmospheric chemistry. While there is consensus about the dominant role of living plants as the major source and the reaction with OH as the major sink of methanol, global methanol budgets diverge considerably in terms of source/sink estimates, reflecting uncertainties in the approache

That's not my Robert! Identity maintainance and other warrants in family members' claims about mistreatment in old-age care

This study has explored how family members of care recipients define and sustain claims of mistreatment in old-age care. Twenty-one informants were recruited from an association of relatives of care recipients in Sweden. Using argumentation analysis, four warrants about mistreatment Were identified from the qualitative interview data: they referred to physical harm, psychological harm, social-care
