The main tenet of immunoecology is that individual variation in immune responsiveness is caused by the costs of immune responses to the hosts. Oxidative damage resulting from the excessive production of reactive oxygen species during immune response is hypothesized to form one of such costs. We tested this hypothesis in experimental coccidian infection model in greenfinches Carduelis chloris. Admi

Changes to the carbon cycle in tropical forests could affect global climate, but predicting such changes has been previously limited by lack of field-based data. Here we show seasonal cycles of the complete carbon cycle for 14, 1ha intensive carbon cycling plots which we separate into three regions: humid lowland, highlands, and dry lowlands. Our data highlight three trends: (1) there is differing

Singing and playing instruments in Swedish secondary schools follow a long tradition, where playing in orchestras or singing in choirs are common historical examples of ensemble activities. In the last decades ensemble playing and teaching have undergone different changes, both in relation to musical practices at large, and with regard to repertoire, use of instruments, technical equipment and not

We report on methods capable of measuring a rms vertical electron beam size of 3 pm with a runs error of less than 10% at a diagnostic beamline at the Swiss Light Source (SLS). This corresponds to a vertical emittance 01 06 pm rad with a 20% rms error. We showed this capability by presenting the theoretical basis for, and the data from, a series of measurements on a stable beam at 1.6 pm rad verti

Humanity has become a major player within the Earth system, particularly by transforming large parts of the land surface and by altering the gaseous composition of the atmosphere. Deforestation for agricultural purposes started thousands of years ago and might have resulted in a detectable human influence on climate much earlier than the industrial revolution. This study presents a first attempt t

Background: The Epidermal Growth Factor Receptor (EGFR) activated Extracellular-signal Regulated Kinase (ERK) pathway is a critical cell signalling pathway that relays the signal for a cell to proliferate from the plasma membrane to the nucleus. Deregulation of the EGFR/ERK pathway due to alterations affecting the expression or function of a number of pathway components has long been associated wi

The galectins are known to be able to recognize and cross-link beta-D-galactopyranoside-containing glycoconjugates as a result of presenting multiple binding sites. This review summarizes efforts in our group for the last ten years towards low-molecular weight chemically modified carbohydrate derivatives. In addition to providing an avenue for improved affinity and galectin-selectivity, we have fo

Cardiopulmonary bypass (CPB) has been shown to be associated with systemic inflammatory response leading to postoperative organ dysfunction. Elucidating the underlying mechanisms and developing protective strategies for the pathophysiological consequences of CPB have been hampered due to the absence of a satisfactory recovery animal model. The purpose of this study was to establish a novel, minima

Emergency and crisis management research is tightly coupled to practical problems. Yet, within that research tradition, surprisingly little has been done in terms of developing a practice of design research. The present report presents literature surveys aimed at investigating how, and to what extent, such research has been conducted. Although the focus is on command and control problems the mater

A combination of the inclusive diffractive cross section measurements made by the H1 and ZEUS Collaborations at HERA is presented. The analysis uses samples of diffractive deep inelastic ep scattering data at a centre-of-mass energy root s = 318 GeV where leading protons are detected by dedicated spectrometers. Correlations of systematic uncertainties are taken into account, resulting in an improv

Indium-tin oxide (ITO) ceramic sputtering targets are widely used in formation of electrically conductive transparent thin films for electrodes in flat panel displays, solar cells, antistatic films and others, and which are commonly produced by a conventional dc magnetron sputtering process. The ceramic targets should be of high purity with a uniform microcrystalline structure and should possess h

Gaucher disease (GD) patients cannot metabolize glycosphingolipids properly due to deficiency of the enzyme glucosylceramidase (GCase). The lack of animal model for GD has hindered comprehensive investigation of disease mechanisms and also the development of curative treatment strategies such as hematopoietic stem cell (HSC) targeted gene therapy. Previous GCase deficient mice have either been let

Purpose – The purpose of this paper is to explore how students construct narratives of themselves as information seekers in a school context where their descriptions of their information activities are assessed and graded. Design/methodology/approach – Blog posts on credibility judgements written by 28 students at a Swedish upper secondary school were analysed through a bottom-up coding process b

Quantitative and fast analysis of gas mixtures is an important task in the field of chemical, security and environmental analysis. In this paper we present a diagnostic approach based on laser-induced breakdown spectroscopy (LIBS). A polarization filter in the signal collection system enables sufficient suppression of elastically scattered light which otherwise reduces the dynamic range of the mea

Objective: The purpose was to describe and characterize what women with rheumatoid arthritis (RA) and juvenile idiopathic arthritis (JIA) perceive as important in considering the performance of daily occupations to perceive good health. Methods: By using a phenomenographic research approach with semi-structured interviews with nine women between the ages of 42 and 65 the core category "Being able
