Early Detection of Preterm Intraventricular Hemorrhage From Clinical Electroencephalography.

Intraventricular hemorrhage is a common neurologic complication of extremely preterm birth and leads to lifelong neurodevelopmental disabilities. Early bedside detection of intraventricular hemorrhage is crucial to enabling timely interventions. We sought to detect early markers of brain activity that preempt the occurrence of intraventricular hemorrhage in extremely preterm infants during the fir

Homozygosity for a null allele of SMIM1 defines the Vel-negative blood group phenotype.

The Vel antigen is present on red blood cells (RBCs) from all humans except rare Vel-negative individuals who can form antibodies to Vel in response to transfusion or pregnancy. These antibodies may cause severe hemolytic reactions in blood recipients. We combined SNP profiling and transcriptional network modeling to link the Vel-negative phenotype to SMIM1, located in a 97-kb haplotype block on c

Modelling the response of yields and tissue C:N to changes in atmospheric CO2 and N management in the main wheat regions of western Europe

Nitrogen (N) is a key element in terrestrial ecosystems as it influences both plant growth and plant interactions with the atmosphere. Accounting for carbon–nitrogen interactions has been found to alter future projections of the terrestrial carbon (C) cycle substantially. Dynamic vegetation models (DVMs) aim to accurately represent both natural vegetation and managed land, not only from a carbon c

Contingency planning for crisis management: Recipe for success or political fantasy?

Contingency planning is widely considered to be an essential role of public authorities. Anticipation of what may happen, coupled with the prior allocation of resources, personnel, equipment, crisis control rooms, tasks, responsibilities and decision guidance/rules, is assumed to maximise the chances of a successful response in the event of a crisis. However, this paper proposes that the relations

A Factor Analytical Approach to the Efficient Futures Market Hypothesis

Most empirical evidence suggests that the efficient futures market hypothesis, henceforth referred to as EFMH, stating that spot and futures prices should cointegrate with a unit slope on futures prices, does not hold, a finding at odds with many theoretical models. This paper argues that these results can be attributed in part to the low power of univariate tests, and that the use of panel data c

Chronology and styles of glaciation in an inter-fjord setting, northwestern Svalbard

A 30-m-thick sedimentary succession at Leinstranda on the southwestern coast of Br circle divide ggerhalv circle divide ya, northwestern Svalbard, spans the two last glacial-interglacial cycles and reveals information on glacial dynamics, sea-level changes and the timing of these events. We investigated the deposits using standard stratigraphical and sedimentological techniques, together with grou

A functional screen for recovery of 4'-phosphopantetheinyl transferase and associated natural product biosynthesis genes from metagenome libraries.

The single-module non-ribosomal peptide synthetase BpsA from Streptomyces lavendulae has the unique ability to autonomously synthesize a coloured product (indigoidine) from a single substrate (l-glutamine), conditional upon activation by a 4'-phosphopantetheinyl transferase (PPTase) partner. We show that bpsA can be expressed in an entD PPTase gene deleted mutant of Escherichia coli to yield a sen

Substrate complexation and aggregation influence the cyclodextrin glycosyltransferase (CGTase) catalyzed synthesis of alkyl glycosides.

Bacillus macerans cyclodextrin glycosyltransferase (CGTase) was used to convert dodecyl-β-maltoside (DDM) to dodecyl-β-maltooctaoside (DDMO) using α-cyclodextrin (α-CD) or starch as glycosyl donors. At 300mM α-CD, varied DDM concentration and 60°C, the reaction obeyed Michaelis-Menten kinetics with a K(m) value of 18mM and a V(max) value of 100U/mg enzyme. However, at 25mM α-CD the reaction

Fatigue Fracture in Dual Modular Revision Total Hip Arthroplasty Stems: Failure Analysis and Computed Tomography Diagnostics in Two Cases.

We report on two patients with fracture of a modular, tapered and distally fixed, uncemented titanium revision hip stem, not previously described. A failure analysis revealed that the cause of the fractures was the development of fatigue cracks in the mid-stem cobalt-chromium modular junction ending in corrosion-fatigue failure. No material defects or stress risers were found in any of the implant

Interaction of the islet nitric oxide system with L-arginine-induced secretion of insulin and glucagon in mice

1. Several recent in vitro studies have suggested that production of nitric oxide (NO) from the islet NO system may have an important regulatory influence on the secretion of insulin and glucagon. In the present paper we have investigated, mainly with an in vivo approach, the influence and specificity of the NO synthase (NOS) blocker NG-nitro-L-arginine methyl ester (L-NAME) on L-arginine-induced

Coupled-Cluster Interaction Energies for 200-Atom Host-Guest Systems

We have developed a method to calculate interaction energies of large systems (such as host-guest or even protein-ligand systems) at the local coupled-cluster with singles, doubles, and perturbative triples level, and with extrapolation to the limit of a complete basis set. The method is based on the polarizable multipole interactions with supermolecular pairs molecular fractionation approach, whi

The importance of work organization on workload and musculoskeletal health - Grocery store work as a model.

We have evaluated the consequences of work organization on musculoskeletal health. Using a postal questionnaire, answered by 1600 female grocery store workers, their main work tasks were identified and four work groups were defined (cashier, picking, and delicatessen work, and a mixed group, who performed a mix of these tasks). The crude odds ratios (ORs) for neck/shoulder complaints were 1.5 (95%

Identification of fibroblast growth factor-8b target genes associated with early and late cell cycle events in breast cancer cells.

Fibroblast growth factor-8 (FGF-8) is implicated in the development and progression of breast cancer and its levels are frequently elevated in breast tumors. The mechanisms driving FGF-8-mediated tumorigenesis are not well understood. Herein we aimed to identify target genes associated with FGF-8b-mediated breast cancer cell proliferation by carrying out a cDNA microarray analysis of genes express

Kontroversen om arbetstidsförkortning : en sociologisk studie av tre försök med arbetstidsförkortning inom Malmö kommun

I denna rapport redovisas dels en övergripande bild över arbetstidsförkortningsdebatten och dels tre försöksprojekt med arbetstidsförkortning som bedrevs under ett och ett halvt år i Malmö kommun. Det hävdas att debatten har utvecklats till en kontrovers i vilken olika grupperingar av debattaktörer kan urskiljas utifrån sina ställningstaganden till reformen, och att det kunskapsunderlag som finns
