A Complex Interaction between Rickettsia conorii and Dickkopf-1 - Potential Role in Immune Evasion Mechanisms in Endothelial Cells
(Journal article; Peer reviewed, 2012)The pathophysiological hallmark of spotted fever group rickettsioses comprises vascular inflammation. Based on the emerging importance of the wingless (Wnt) pathways in inflammation and vascular biology, we hypothesized ... -
A spatio-temporally explicit random encounter model for large-scale population surveys
(Journal article; Peer reviewed, 2016)Random encounter models can be used to estimate population abundance from indirect data collected by non-invasive sampling methods, such as track counts or camera-trap data. The classical Formozov–Malyshev–Pereleshin (FMP) ... -
An integrated analysis of molecular acclimation to high light in the marine diatom Phaeodactylum tricornutum
(Journal article; Peer reviewed, 2009-11-03)Photosynthetic diatoms are exposed to rapid and unpredictable changes in irradiance and spectral quality, and must be able to acclimate their light harvesting systems to varying light conditions. Molecular mechanisms behind ... -
An oil containing EPA and DHA from transgenic Camelina sativa to replace marine fish oil in feeds for Atlantic salmon (Salmo salar L.): Effects on intestinal transcriptome, histology, tissue fatty acid profiles and plasma biochemistry
(Journal article; Peer reviewed, 2017)New de novo sources of omega 3 (n-3) long chain polyunsaturated fatty acids (LC-PUFA) are required as alternatives to fish oil in aquafeeds in order to maintain adequate levels of the beneficial fatty acids, eicosapentaenoic ... -
Anchoring plant metallothioneins to the inner face of the plasma membrane of Saccharomyces cerevisiae cells leads to heavy metal accumulation
(Journal article; Peer reviewed, 2017)In this study we engineered yeast cells armed for heavy metal accumulation by targeting plant metallothioneins to the inner face of the yeast plasma membrane. Metallothioneins (MTs) are cysteine-rich proteins involved in ... -
Arabidopsis thaliana MIRO1 and MIRO2 GTPases Are Unequally Redundant in Pollen Tube Growth and Fusion of Polar Nuclei during Female Gametogenesis
(Journal article; Peer reviewed, 2011)MIRO GTPases have evolved to regulate mitochondrial trafficking and morphology in eukaryotic organisms. A previous study showed that T-DNA insertion in the Arabidopsis MIRO1 gene is lethal during embryogenesis and affects ... -
Are cuckoos maximizing egg mimicry by selecting host individuals with better matching egg phenotypes?
(Journal article; Peer reviewed, 2012)Background: Avian brood parasites and their hosts are involved in complex offence-defense coevolutionary arms races. The most common pair of reciprocal adaptations in these systems is egg discrimination by hosts and egg ... -
Biotransformation and Oxidative Stress Responses in Captive Nile Crocodile (Crocodylus niloticus) Exposed to Organic Contaminants from the Natural Environment in South Africa
(Journal article; Peer reviewed, 2015)In the present study, the biotransformation and oxidative stress responses in relation to chemical burden in the liver of male and female Nile crocodiles—Crocodylus niloticus— from a commercial crocodile farm passively ... -
Coevolution in Action: Disruptive Selection on Egg Colour in an Avian Brood Parasite and its Host
(Journal article; Peer reviewed, 2010)Background: Trait polymorphism can evolve as a consequence of frequency-dependent selection. Coevolutionary interactions between hosts and parasites may lead to selection on both to evolve extreme phenotypes deviating ... -
Computational Visual Stress Level Analysis of Calcareous Algae Exposed to Sedimentation
(Journal article; Peer reviewed, 2016)This paper presents a machine learning based approach for analyses of photos collected from laboratory experiments conducted to assess the potential impact of water-based drill cuttings on deep-water rhodolith-forming ... -
Context Consistency and Seasonal Variation in Boldness of Male Two-Spotted Gobies
(Journal article; Peer reviewed, 2014)In order to attribute the behaviour of an animal to its personality it is important to study whether certain behavioural traits show up consistently across a variety of contexts. The aim of this study was to investigate ... -
Contrasting Patterns of Genetic Structuring in Natural Populations of Arabidopsis lyrata Subsp. petraea across Different Regions in Northern Europe
(Journal article; Peer reviewed, 2014-09-16)Level and partitioning of genetic diversity is expected to vary between contrasting habitats, reflecting differences in strength of ecological and evolutionary processes. Therefore, it is necessary to consider processes ... -
Cytosolic phospholipase A2 modulates TLR2 signaling in synoviocytes
(Journal article; Peer reviewed, 2015)Rheumatoid arthritis (RA) is an autoimmune disease characterized by chronic synovitis leading to destruction of cartilage and bone. PLA2 enzymes are key players in inflammation regulating the release of unsaturated fatty ... -
Cytosolic phospholipase A2 regulates TNF-induced production of joint destructive effectors in synoviocytes
(Journal article; Peer reviewed, 2013)Introduction: Rheumatoid arthritis (RA) is an inflammatory disease of the joint characterized by chronic synovitis causing pain, swelling and loss of function due to destruction of cartilage and bone. The complex series ... -
Diversity, Loss, and Gain of Malaria Parasites in a Globally Invasive Bird
(Journal article; Peer reviewed, 2011)Invasive species can displace natives, and thus identifying the traits that make aliens successful is crucial for predicting and preventing biodiversity loss. Pathogens may play an important role in the invasive process, ... -
Effects of an Offshore Eind Farm (OFW) on the Common Shore Crab Carcinus maenas: Tagging Pilot Experiments in the Lillegrund Offshore Wind Farm (Sweden).
(Journal article; Peer reviewed, 2016)Worldwide growth of offshore renewable energy production will provide marine organisms with new hard substrate for colonization in terms of artificial reefs. The artificial reef effect is important when planning offshore ... -
Endoparasite infection has both short- and long-term negative effects on reproductive success of female house sparrows, as revealed by faecal parasitic egg counts
(Journal article; Peer reviewed, 2015)Parasites have the potential to severely reduce host reproductive success. However, the effects of endoparasites on reproductive success have not received the same amount of attention as the effects of parasites on host ... -
First-time Migration in Juvenile Common Cuckoos Documented by Satellite Tracking
(Journal article; Peer reviewed, 2016)Being an obligate parasite, juvenile common cuckoos Cuculus canorus are thought to reach their African wintering grounds from Palearctic breeding grounds without guidance from experienced conspecifics but this has not been ... -
