Keeping It Steady. Older Adults Perform More Consistently on Cognitive Tasks Than Younger Adults

People often attribute poor performance to having bad days. Given that cognitive aging leads to lower average levels of performance and more moment-to-moment variability, one might expect that older adults should show greater day-to-day variability and be more likely to experience bad days than younger adults. However, both researchers and ordinary people typically sample only one performance per

Variants at chromosome 20 (ASIP locus) and melanoma risk

Agouti signaling protein (ASIP) locus on chromosome 20q11 is implicated, as shown by genome-wide association studies, in phenotype variation and melanoma risk. We genotyped 837 melanoma cases and 1,154 controls for 21 single nucleotide polymorphisms (SNPs) informative for 495 polymorphisms at the locus. Our data showed an increased risk of melanoma (odds ratio [OR] 1.27, 95% confidence interval [9

Everolimus combined with gefitinib in patients with metastatic castration-resistant prostate cancer: Phase 1/2 results and signaling pathway implications.

The effects of mammalian target of rapamycin (mTOR) inhibition are limited by feedback reactivation of receptor tyrosine kinase signaling in phosphatase and tensin homolog-null tumors. Thus, this study tested the combination of mTOR inhibition (everolimus) and epidermal growth factor receptor inhibition (gefitinib) in castration-resistant prostate cancer (CRPC).

A serious bleeding complication with injury of the corona mortis with the TVT-Secur procedure

We report a serious complication following a TVT-Secur procedure due to injury of the corona mortis requiring a surgical intervention for removal of 1 l of clotted blood from the space of Retzius. The corona mortis is an anomaly of the vessel combining the obturator and epigastric arteries passing over the superior pubic ramus, well known to hernia and orthopedic surgeons but probably less well kn

Consolidation and development roadmap of the EMI middleware

Scientific research communities have benefited recently from the increasing availability of computing and data infrastructures with unprecedented capabilities for large scale distributed initiatives. These infrastructures are largely defined and enabled by the middleware they deploy. One of the major issues in the current usage of research infrastructures is the need to use similar but often incom

Urinary diversion: how experts divert.

To determine the rates of the available urinary diversion options for patients treated with radical cystectomy for bladder cancer in different settings (pioneering institutions, leading urologic oncology centers, and population based).

Momentary Contentment: A Modern Version of an Old Survival Culture

This is a classic grounded theory based in longitudinal data from everyday life in an environment in Northern Norway characterized by long distances, a harsh climate and people living close to nature and each other. The place has a history of poverty and isolation. Yet, old survival strategies prevail despite modernisation. The theory reveals a culture of momentary contentment with three dimension

Fleeing the Flowing Commons: Robert Thom, Water Reservoir Schemes, and the Shift to Steam Power in Early Nineteenth-Century Britain

In the 1820s and 1830s, British industry faced a choice between two energy sources to fuel its expansion: water and coal. A series of water reservoir schemes were proposed to scale up the power capacity of rivers in the central manufacturing districts, but the schemes with the largest potentials were never realized. Instead, the industry veered toward steam power, fatefully linking self-sustaining

Public Faith and the Common Good : A Radical Messianic Proposal

The article inquires into the implications of Christianity not being a religious perspective among others in the contemporary Western debate on religious pluralism. A quick glance at a recent debate in Sweden serves to demonstrate how Christianity, although marginalized in its traditional forms, remains a dominating cultural interpretative scheme that continues to influence the majority’s view on

Making marketswith active labor market policies: the influence of political parties, welfare state regimes, and economic change on spending on different types of policies

Active labor market policies consist of a diverse set of policy tools with which to address joblessness and the degree to which governments invest in various policies as a response to rising unemployment varies widely. Fleshing out the determinants by policy type holds the promise of illuminating more clearly contestation over activation. To this end, this study analyzes the role of partisanship a

Animal Orientation Strategies for Movement in Flows

For organisms that fly or swim, movement results from the combined effects of the moving medium - air or water - and the organism's own locomotion. For larger organisms, propulsion contributes significantly to progress but the flow usually still provides significant opposition or assistance, or produces lateral displacement ('drift'). Animals show a range of responses to flows, depending on the di

Diagnostic properties of metabolic perturbations in rheumatoid arthritis

Introduction: The aim of this study was to assess the feasibility of diagnosing early rheumatoid arthritis (RA) by measuring selected metabolic biomarkers. Methods: We compared the metabolic profile of patients with RA with that of healthy controls and patients with psoriatic arthritis (PsoA). The metabolites were measured using two different chromatography-mass spectrometry platforms, thereby giv

Sales Maximization or Profit Maximization? How State Shareholders Discipline their CEOs in China*

This study examines the determinants of Chief Executive Officer (CEO) turnover in Chinese state-owned firms. Based on a sample of 1 555 turnover cases among listed firms in China during the period 19992003, we obtain three main results. First, CEO turnover is negatively related to the sales performance but not the profitability of the core business. Second, the negative relationship between CEO tu

Evidence for SMAD3 as a modifier of breast cancer risk in BRCA2 mutation carriers

Introduction: Current attempts to identify genetic modifiers of BRCA1 and BRCA2 associated risk have focused on a candidate gene approach, based on knowledge of gene functions, or the development of large genome-wide association studies. In this study, we evaluated 24 SNPs tagged to 14 candidate genes derived through a novel approach that analysed gene expression differences to prioritise candidat

tmRNA to the rescue Structural motives for the salvage of stalled ribosomes

During translation, mRNA molecules are incidentally damaged, leaving the ribosome unable to reach or recognize the stop codon and thus stalled with mRNA and a potentially harmful polypeptide product attached to tRNA in the ribosomal P-site. In bacteria, a process called trans-translation has evolved, where a protein-RNA complex (smpB-tmRNA) mimicks the role of aminoacyl charged tRNA in the ribosom

The Role of the ECG in Diagnosis, Risk Estimation, and Catheterization Laboratory Activation in Patients with Acute Coronary Syndromes: A Consensus Document

The electrocardiogram (ECG) is the most widely used imaging tool helping in diagnosis and initial management of patients presenting with symptoms compatible with acute coronary syndrome. Acute ischemia affects the configuration of the QRS complexes, the ST segments and the T waves. The ECG should be read along with the clinical assessment of the patient. ST segment elevation (and ST depression in

Comparison of standardised dietary folate intake across ten countries participating in the European Prospective Investigation into Cancer and Nutrition

Folate plays an important role in the synthesis and methylation of DNA as a cofactor in one-carbon metabolism. Inadequate folate intake has been linked to adverse health events. However, comparable information on dietary folate intake across European countries has never been reported. The objective of the present study was to describe the dietary folate intake and its food sources in ten countries

Understanding and influencing teaching and learning cultures at university - A network approach

Academic cultures might be perceived as conservative, at least in terms of development of teaching and learning. Through a lens of network theory this conceptual article analyses the pattern of pathways in which culture is constructed through negotiation of meaning. The perspective contributes to an understanding of culture construction and maintenance with a potential to aid academic developers a
