The Electrically Wired Molybdenum Domain of Human Sulfite Oxidase is Bioelectrocatalytically Active

We report electron transfer between the catalytic molybdenum cofactor (Moco) domain of human sulfite oxidase (hSO) and electrodes through a poly(vinylpyridine)-bound [osmium(N,N'-methyl-2,2'-biimidazole)(3)](2+/3+) complex as the electron-transfer mediator. The biocatalyst was immobilized in this low-potential redox polymer on a carbon electrode. Upon the addition of sulfite to the immobilized sep

Zircon U-Pb-Hf evidence for subduction related crustal growth and reworking of Archaean crust within the Palaeoproterozoic Birimian terrane, West African Craton, SE Ghana

Zircon Lu-Hf isotopic data from granites of southern and northwestern Ghana have been used to investigate the contribution of reworked Archaean bedrock to the Birimian crust of Ghana, West African Craton. Zircon from seven localities in southern Ghana and one locality in western Ghana were analysed. Combined U-Pb and Lu-Hf isotope data suggest juvenile crustal addition between 2.3–2.1 Ga, with a s

Bidirectional correction in social judgments: How a cue to the risk of bias causes more favorable ratings of some groups but less favorable of others.

Correction of judgments of people of different ethnicities and sexes was explored by exposing participants to cues to the risk of making biased judgments (from explicit warnings to subtle hints). In three experiments, a three-way interaction was revealed, where the effect of a cue to bias varied as a function of both the ethnicity and sex of the target person. Some targets (White males) were gener

The Postcolonial has Moved into Europe: Bordering, Security and Ethno-Cultural Belonging

The legacy of European colonialisms and nationalisms has conditioned immigration and citizenship policies that inform the postcolonial move into Europe. This article questions the assumptions that undergird conceptions of boundary, territory and ethno-cultural belonging in the constitution of Europe. In particular, it emphasizes how Europe and European integration must be read within the context o

Fibrinogen and FXIII dose response effects on albumin-induced coagulopathy.

Objectives. Natural colloid albumin induces a lesser degree of dilutional coagulopathy than synthetic colloids. Fibrinogen concentrate has emerged as a promising strategy to treat coagulopathy, and factor XIII (FXIII) works synergistically with fibrinogen to correct coagulopathy following haemodilution with crystalloids. Our objectives were to examine the ability of fibrinogen and FXIII concentrat

Comparison of neuropsychological and brain imaging data in pediatric brain tumor patients surviving more than 10 years

AIM: To explore the relationship between neuropsychological outcome and magnetic resonance imaging (MRI) findings in paediatric brain tumour patients surviving more than 10 years. BACKGROUND: Cognitive late sequelae after paediatric brain tumour have a multifactorial origin. Low age at diagnosis, cranial radiation therapy, intrathecal methotrexate treatment and increased intracranial pressure are

Controlling the microclimate of the skin though the application of occluding films

The skin barrier is a responding membrane that separates environments with profoundly different water contents. This implies a substantial water gradient across the skin membrane, which controls transepidermal water loss (TEWL) and skin hydration. We define the microclimate of the skin as the activity of water in the outermost layer of skin. By applying an occluding film composed of a pharmaceutic

Pollinator communities in strawberry crops - variation at multiple spatial scales.

Predicting potential pollination services of wild bees in crops requires knowledge of their spatial distribution within fields. Field margins can serve as nesting and foraging habitats for wild bees and can be a source of pollinators. Regional differences in pollinator community composition may affect this spill-over of bees. We studied how regional and local differences affect the spatial distrib

Genome-wide analysis associates familial colorectal cancer with increases in copy number variations and a rare structural variation at 12p12.3

Colorectal cancer (CRC) is one of the most common cancer worldwide. However, a large number of genetic risk factors involved in CRC have not been understood. Copy number variations (CNVs) might partly contribute to the missing heritability of CRC. An increased overall burden of CNV has been identified in several complex diseases, whereas the association between the overall CNV burden and CRC risk

Reduced insulin secretion correlates with decreased expression of exocytotic genes in pancreatic islets from patients with type 2 diabetes.

Reduced insulin release has been linked to defect exocytosis in β-cells. However, whether expression of genes suggested to be involved in the exocytotic process (exocytotic genes) is altered in pancreatic islets from patients with type 2 diabetes (T2D), and correlate to insulin secretion, needs to be further investigated. Analysing expression levels of 23 exocytotic genes using microarray revealed

Diameter Limitation in Growth of III-Sb-Containing Nanowire Heterostructures.

The nanowire geometry offers significant advantages for exploiting the potential of III-Sb materials. Strain due to lattice mismatch is efficiently accommodated, and carrier confinement effects can be utilized in tunneling and quantum devices for which the III-Sb materials are of particular interest. It has however proven difficult to grow thin (below a few tens of nanometers), epitaxial III-Sb na

Search for Magnetic Monopoles in root s=7 TeV pp Collisions with the ATLAS Detector

This Letter presents a search for magnetic monopoles with the ATLAS detector at the CERN Large Hadron Collider using an integrated luminosity of 2.0 fb(-1) of pp collisions recorded at a center-of-mass energy root s = 7 TeV. No event is found in the signal region, leading to an upper limit on the production cross section at 95% confidence level of 1.6/epsilon fb for Dirac magnetic monopoles with t

Multiple legitimacy narratives and planned organizational change

This article explores the cultural narratives through which members of organizations define legitimacy during prolonged periods of change. We view legitimacy work as a cultural practice and interpretive process that takes the form of organizational narratives. We show how the shifting configurations of internal power relations shape both the choice and the meaning attached to the varied legitimacy

Oxidative stress and information content of black and yellow plumage coloration: An experiment with greenfinches

Carotenoid and melanin pigments in the plumage of birds are hypothesized to be sensitive to oxidative stress. We manipulated oxidative status of captive greenfinches (Carduelis chloris L.) by the administration of buthionine sulfoximine (BSO), a selective inhibitor of the synthesis of glutathione (GSH), an intracellular antioxidant. Half of the birds in the treated group, as well as in the control

Invasion rate and population characteristics of the round goby Neogobius melanostomus: effects of density and invasion history

Round goby Neogobius melanostomus is currently one of the most wide-ranging invasive fish species in Europe and North America. The present study demonstrates how the distribution of round goby has expanded from 2008 to 2013 at a rate of about 30 km yr(-1) along the Danish coastline in the western Baltic Sea. Further analyses showed that fish from an established high-density round goby population w

Mitochondrial proteome analysis reveals altered expression of voltage dependent anion channels in pancreatic beta-cells exposed to high glucose

Chronic hyperglycemia leads to deterioration of insulin release from pancreatic beta-cells as well as insulin action on peripheral tissues. However, the mechanism underlying beta-cell dysfunction resulting from glucose toxicity has not been fully elucidated. The aim of the present study was to define a set of alterations in mitochondrial protein profiles of pancreatic beta-cell line in response to

Analytical Gradients of the Second-Order Moller-Plesset Energy Using Cholesky Decompositions

An algorithm for computing analytical gradients of the second-order MOller-Plesset (MP2) energy using density fitting (DF) is presented. The algorithm assumes that the underlying canonical Hartree-Fock reference is obtained with the same auxiliary basis set, which we obtain by Cholesky decomposition (CD) of atomic electron repulsion integrals. CD is also used for the negative semidefinite MP2 ampl

Apolipoprotein M binds oxidized phospholipids and increases the antioxidant effect of HDL

Objective: Oxidation of LDL plays a key role in the development of atherosclerosis. HDL may, in part, protect against atherosclerosis by inhibiting LDL oxidation. Overexpression of HDL-associated apolipoprotein M (apoM) protects mice against atherosclerosis through a not yet clarified mechanism. Being a lipocalin, apoM contains a binding pocket for small lipophilic molecules. Here, we report that

Grants to Needy Countries? A Study of Aid Composition between 1975 and 2005

This article discusses whether the poorest and most indebted countries receive aid in the form of grants rather than loans, by studying bilateral aid flows to low- and middle-income countries between 1975 and 2005. The empirical analysis finds no evidence that more indebted countries receive a higher grant component, but it does show that poorer countries receive a significantly higher grant compo
