Sex-Specific Patterns of Aging in Sexual Ornaments and Gametes

Sex differences in age-dependent mortality and reproductive success are predicted to drive the evolution of sexually dimorphic patterns of reproductive investment over life. However, this prediction has not been fully explored because it is difficult to measure primary and secondary sexual traits over the life spans of males and females. Here we studied a population of fowl, Gallus gallus, to gain

Cyclooxygenase-2 inhibition and thromboxane A (2) receptor antagonism attenuate hypoxic pulmonary vasoconstriction in a porcine model.

AIM: Hypoxic pulmonary vasoconstriction (HPV) causes pulmonary hypertension that may lead to right heart failure. We hypothesized that the COX-2 inhibitor nimesulide and the thromboxane A (2) receptor antagonist daltroban would attenuate HPV. METHODS: Haemodynamic measurements and blood sampling were performed in 18 anaesthetized, mechanically ventilated pigs, with mean ± SEM weights of 31.3 ±

Working conditions, health and productivity among dentists in Swedish public dental care - a prospective study during a 5-year period of rationalisation

In recent decades, comprehensive rationalisations have been implemented in public dentistry in Sweden. How rationalisations affect working conditions, health and production from a long-term perspective has been poorly investigated. This study aims to analyse changes and associations in dentists' working conditions, health and productivity during a 5-year period. In 2003 and 2008, 65 dentists respo

Layered Reconstruction for Defocus and Motion Blur

Light field reconstruction algorithms can substantially decrease the noise in stochastically rendered images. Recent algorithms for defocus blur alone are both fast and accurate. However, motion blur is a considerably more complex type of camera effect, and as a consequence, current algorithms are either slow or too imprecise to use in high quality rendering. We extend previous work on real-time l

Large Eddy Simulation of flame stabilisation dynamics and vortex control in a lifted H2/N2 jet flame

Flame stabilisation in (highly) preheated mixture is common in several industrial applications. When the reactants are injected separately in the device (usually at high-speed), the flame is lifted so that the fuel and oxidant first mix to give an ignitable mixture. If the temperature of the mixture is adequate, it auto-ignites stabilizing the flame. Here we focus on an academic lifted jet flame a

In Search of Heimat: A Note on Franz Kafka's Concept of Law

Are Fran T Kafka's representations of law and legality figments of his imagination, or do they go beyond his obsessive probing of his neurosis to reflect issues that also engaged the social and legal theorists of his time? Does Kafka's conception of law offer anything new in respect to law, justice, and bureaucracy that was not explored by his contemporaries or by later legal scholars? This paper

Appendicitis in children from a gender perspective.

The incidence in appendicitis and the appendectomy rate are different between boys and girls. This study aimed to further evaluate appendicitis in children from a gender perspective. Gender differences in presentation, perioperative care, and outcome after appendectomy were examined.

Staphylococcal Proteases Aid in Evasion of the Human Complement System.

Staphylococcus aureus is an opportunistic pathogen that presents severe health care concerns due to the prevalence of multiple antibiotic-resistant strains. New treatment strategies are urgently needed, which requires an understanding of disease causation mechanisms. Complement is one of the first lines of defense against bacterial pathogens, and S. aureus expresses several specific complement inh

The next-generation ARC middleware

The Advanced Resource Connector (ARC) is a light-weight, non-intrusive, simple yet powerful Grid middleware capable of connecting highly heterogeneous computing and storage resources. ARC aims at providing general purpose, flexible, collaborative computing environments suitable for a range of uses, both in science and business. The server side offers the fundamental job execution management, infor

The Power of EU Masculinities: A Feminist Contribution to European Integration Theory

This article advances feminist analysis in the study of European integration through a focus on gender power in relation to masculinity constructs. It takes issue with the fact that gender studies tend to equate gender with women. It sketches a feminist contribution to integration theory, where the EU is perceived as gender regimes at multiple levels. Gender identity constructs-masculinities and f

Familial Risk of Small Intestinal Carcinoid and Adenocarcinoma

BACKGROUND & AIMS: Small intestinal cancer (SIC) is rare, and its etiology is poorly understood. We compared clusters of families with SICs of different histologic subtypes. METHODS: By using the nationwide family cancer data sets of Sweden and Finland, we identified a cohort of 9964 first-degree relatives of 1799 patients with SIC, diagnosed from 1961 through 2009. Data were collected from ti

Natural Resource Management: Challenges and Policy Options

Much of the improvement in living standards in developed and developing countries is attributable to the exploitation of nonrenewable and renewable resources. The problem is to know when the exploitation occurs at rates and with technologies that are sustainable. If the technologies used are not sustainable, resource exploitation presents a serious problem for the future because welfare will decre

Measurement of the production of a W boson in association with a charm quark in pp collisions at root s=7 TeV with the ATLAS detector

The production of a W boson in association with a single charm quark is studied using 4.6 fb(-1) of pp collision data at root s = 7 TeV collected with the ATLAS detector at the Large Hadron Collider. In events in which a W boson decays to an electron or muon, the charm quark is tagged either by its semileptonic decay to a muon or by the presence of a charmed meson. The integrated and differential

Development of an Electrochemical Meta-Ion Biosensor Using Self-Assembled Peptide Nanofibrils

This article describes the combination of self-assembled peptide nanofibrils with metal electrodes for the development of an electrochemical metal-ion biosensor. The biological nanofibrils were immobilized on gold electrodes and used as biorecognition elements for the complexation with copper ions. These nanofibrils were obtained under aqueous conditions, at room temperature and outside the clean

From BASIS to MIRACLES: Benchmarking and perspectives for high-resolution neutron spectroscopy at the ESS

Results based on virtual instrument models for the first high-flux, high-resolution, spallation based, backscattering spectrometer, BASIS are presented in this paper. These were verified using the Monte Carlo instrument simulation packages McStas and VITESS. Excellent agreement of the neutron count rate at the sample position between the virtual instrument simulation and experiments was found, in

Subtypes of fruit and vegetables, variety in consumption and risk of colon and rectal cancer in the European Prospective Investigation into Cancer and Nutrition.

Previously, a lower risk of colorectal cancer was observed with fruit and vegetable consumption in the European Prospective Investigation into Cancer and Nutrition within a follow-up period of nine years which was not fully supported by a recent meta-analysis. Therefore, we were interested in the relation with extended follow-up, also focusing on single subtypes and variety of intake of fruit and

Clickable molecularly imprinted nanoparticles.

Terminal alkynyl and azide groups are introduced on the surface of molecularly imprinted core-shell nanoparticles using precipitation polymerization. These clickable groups enable simple nanoparticle conjugation and surface modification under mild reaction conditions, opening new opportunities for nanoparticle-based assays and chemical sensing.

Completing the European Union Customs Union: The Effects of Trade Procedure Harmonization

In this article, it is pointed out that the European Union does not have a harmonized practice when it comes to trade procedures, implying that countries in the rest of the world face different trade barriers depending on which EU country they ship their goods to. Estimating the impact of trade procedures on exports from non-EU countries, a highly statistically significant and negative effect is f
