Comparison of Two Methods of Fatigue Testing Bone Cement.

Two different methods have been used to fatigue test four bone cements. Each method has been used previously, but the results have not been compared. The ISO 527 based method tests a minimum of 10 samples over a single stress range in tension only and uses Weibull analysis to calculate the median number of cycles to failure and the Weibull modulus. The ASTM F2118 test regime uses fewer specimens a

Recurrent mutations refine prognosis in chronic lymphocytic leukemia.

Through the European Research Initiative in CLL (ERIC), we screened 3490 patients with chronic lymphocytic leukemia (CLL) for mutations within the NOTCH1 (n=3334), SF3B1 (n=2322), TP53 (n=2309), MYD88 (n=1080) and BIRC3 (n=919) genes, mainly at diagnosis (75%) and prior to treatment (>90%). BIRC3 mutations (2.5%) were associated with unmutated IGHV genes (U-CLL), del(11q) and trisomy 12, whereas M

The CO2 release and Oxygen uptake from Fossil Fuel Emission Estimate (COFFEE) dataset: Effects from varying oxidative ratios

We present a global dataset of CO2 emissions and O2 uptake associated with the combustion of different fossil fuel types. To derive spatial and temporal patterns of oxygen uptake, we combined high-resolution CO2 emissions from the EDGAR (Emission Database for Global Atmospheric Research) inventory with country level information on oxidative ratios, based on fossil fuel consumption data from the UN

Trophic Factor Gene Therapy for Parkinson's Disease

Parkinson's disease (PD) is a chronic and progressive neurodegenerative movement disorder for which there is presently no cure. Pharmacological remedies targeting the dopaminergic network are relatively effective at ameliorating motor deficits, especially in the early stages of the disease, but none of these therapies are curative and many generate their own problems. Recent advances in PD researc

Challenges for Children and Adolescents With Cancer in Europe: The SIOP-Europe Agenda

In Europe, 6,000 young people die of cancer yearly, the commonest disease causing death beyond the age of 1 year. In addition, 300,000-500,000 European citizens are survivors of a childhood cancer and up to 30% of them have severe long-term sequelae of their treatment. Increasing both cure and quality of cure are the two goals of the European paediatric haematology/oncology community. SIOPE coordi

Radiofrequency Ablation as Initial Therapy in Paroxysmal Atrial Fibrillation

Background There are limited data comparing radiofrequency catheter ablation with antiarrhythmic drug therapy as first-line treatment in patients with paroxysmal atrial fibrillation. Methods We randomly assigned 294 patients with paroxysmal atrial fibrillation and no history of antiarrhythmic drug use to an initial treatment strategy of either radiofrequency catheter ablation (146 patients) or the

Against the Small Clause Hypothesis : Evidence from Swedish relative clause extractions

On the basis of data from Swedish, this paper examines the Small Clause Hypothesis (Kush & Lindahl 2011, Kush, Omaki & Hornstein 2013) proposed to account for relative clause (RC) extractions in Mainland Scandinavian. The hypothesis predicts that extraction possibilities differ for relative clauses in the complement of verbs which select and verbs which do not select a small clause (SC), a

Enhancer hijacking activates GFI1 family oncogenes in medulloblastoma.

Medulloblastoma is a highly malignant paediatric brain tumour currently treated with a combination of surgery, radiation and chemotherapy, posing a considerable burden of toxicity to the developing child. Genomics has illuminated the extensive intertumoral heterogeneity of medulloblastoma, identifying four distinct molecular subgroups. Group 3 and group 4 subgroup medulloblastomas account for most

Inventory Control in Divergent Supply Chains with Time-Based Dispatching and Shipment Consolidation

This article analyses a divergent supply chain consisting of a central warehouse and N nonidentical retailers. The focus is on joint evaluation of inventory replenishment and shipment consolidation effects. A time-based dispatching and shipment consolidation policy is used at the warehouse in conjunction with real-time point-of-sale data and centralized inventory information. This represents a com

The Antimicrobial Peptide LL-37 Alters Human Osteoblast Ca Handling and Induces Ca(2+)-Independent Apoptosis.

The human antimicrobial peptide cathelicidin LL-37 has, besides its antimicrobial properties, also been shown to regulate apoptosis in a cell type-specific manner. Mechanisms involved in LL-37-regulated apoptotic signaling are not identified. Here, we show that LL-37 reduces the human osteoblast-like MG63 cell number and cell viability in the micromolar concentration range with an IC(50) value of

U0126 attenuates cerebral vasoconstriction and improves long-term neurologic outcome after stroke in female rats.

Sex differences are well known in cerebral ischemia and may impact the effect of stroke treatments. In male rats, the MEK1/2 inhibitor U0126 reduces ischemia-induced endothelin type B (ETB) receptor upregulation, infarct size and improves acute neurologic function after experimental stroke. However, responses to this treatment in females and long-term effects on outcome are not known. Initial expe

On mechanisms and models of multi-component gas diffusion in porous structures of fuel cell electrodes

Small scale particles/pores from micrometers and down to nanometers often occur in multi-functional porous electrodes in fuel cells, to enhance the catalytic reaction activities and accordingly the cell performance. Multi-component and -phase mass transport phenomena of reactants and products are strongly coupled with other transport processes as well as various reactions. All these processes form

Cardiac output and cardiac index measured with cardiovascular magnetic resonance in healthy subjects, elite athletes and patients with congestive heart failure

Background: Cardiovascular Magnetic Resonance (CMR) enables non-invasive quantification of cardiac output (CO) and thereby cardiac index (CI, CO indexed to body surface area). The aim of this study was to establish if CI decreases with age and compare the values to CI for athletes and for patients with congestive heart failure (CHF). Methods: CI was measured in 144 healthy volunteers (39 +/- 16 ye

Energy selective neutron radiography in material research

Energy selective neutron radiography was performed to describe a complex structure in polycrystalline materials. Experiments were performed with currently the highest energy and spatial resolutions achieved simultaneously, by employing a double crystal monochromator for selecting narrow energy bands from the initially polychromatic neutron beam and the neutron absorbing scintillator screen coupled

Complicated, complex and compliant: Best practice in obstetrics

Abstract in Undetermined In this study the distinction between complicated and complex is used to shed some light on compliance with best-practice guidelines. Data was gathered related to obstetric practice in labor wards and operating theatres at two Scandinavian hospitals, one of them being a university hospital, and in a training facility. The complexity of obstetrical intervention is analyzed

Swedish National Register for Retinopathy of Prematurity (SWEDROP) and the Evaluation of Screening in Sweden

Objectives: To evaluate screening for retinopathy of prematurity (ROP) in Sweden and to investigate possible modifications of the present screening guidelines. Methods: Infants in Sweden with a gestational age (GA) of 31 weeks + 6 days or less are screened for ROP. Data from the Swedish national register for ROP (SWEDROP) during 2008 and 2009 were extracted and compared with a national perinatal q

Urban environment and well-being: cross-cultural studies on Perceived Residential Environment Quality Indicators (PREQIs)

Architectural and environmental psychology literature has shown the importance of urban design in provoking stress feelings or enhancing well-being and quality of life. The aim of this contribution is to show the main results of a set of cross-cultural survey studies concerning the perceived quality of urban features at the neighbourhood level. A questionnaire was used including the extended or th

Epigenetic regulation of glucose-stimulated osteopontin (OPN) expression in diabetic kidney.

Diabetes nephropathy (DN) is the leading cause of end stage renal disease and it affects up to 40% of diabetic patients. In addition to hyperglycemia, genetic factors are thought to contribute to the development of DN, but few if any genetic factors have been convincingly linked to DN. Other possible mechanisms may involve epigenetic regulation of glucose-stimulated gene activity which was suggest
