The associations of maternal exposure to black carbon and foetal growth risks in Southern SwedenNARA Subscribed
Black carbon (BC) is an air pollutant of emerging concern, and further evidence is needed to understand its health effects. This study investigates the association between gestational BC exposure and birth outcomes, and whether these effects are independent of particulate matter with an aerodynamic diameter of ≤ 2.5 μm (PM 2.5 ) exposure. We used data from the population-based birth cohort, Maternal Air Pollution in Southern S...
Whether the magnitude of individual cytokine, cellular, and clinical responses to the intravenous lipopolysaccharide (LPS) challenge is constant in individuals over extended time periods is unknown. Nine healthy volunteers received an intravenous LPS injection of 2 ng/kg bodyweight twice at intervals of at least one year. Circulating cytokines and leukocyte subsets were quantified using a multiplex immunoassay and cytometry by...
Trait‐based approaches have been increasingly used to relate plants to soil microbial communities. Using the recently described root economics space as an approach to explain the structure of soil‐borne fungal communities, our study in a grassland diversity experiment reveals distinct root trait strategies at the plant community level. In addition to significant effects of plant species richness, we show that the collaboration...
Purification and concentration of infectious koi herpesvirus using steric exclusion chromatographyNARA Subscribed
Koi herpesvirus (KHV) is the causative agent of a koi herpesvirus disease (KHVD) inducing high mortality rates in common carp and koi ( Cyprinus carpio ). No widespread effective vaccination strategy has been implemented yet, which is partly due to side effects of the immunized fish. In this study, we present an evaluation of the purification of infectious KHV from host cell protein and DNA, using the steric exclusion chromato...
Plastic debris is ubiquitous in all ecosystems and has even reached locations that humans will hardly reach such as the deep ocean floor and the atmosphere. Research has highlighted that plastic debris is now pervasive even in remote Arctic regions. While modeling projections indicated local sources and long-distance transport as causes, empirical data about its origin and sources are scarce. Data collected by citizen scientis...
Rainbow trout ( Oncorhynchus mykiss ) and common carp ( Cyprinus carpio ) are the two most common species in traditional fish farming in Germany. Their aquaculture is threatened upon others by viruses that can cause a high mortality. Therefore, this work focuses on three viruses—viral haemorrhagic septicaemia virus, infectious hematopoietic necrosis virus and cyprinid herpesvirus 3 (CyHV‐3)—that endanger these species. To prev...
Virucidal effects of various agents—including protease—against koi herpesvirus and viral haemorrhagic septicaemia virusNARA Subscribed
In a search for alternative, environmentally friendly and effective disinfecting agents, a commercially available protease—Neutrase ® —was tested in this work for inactivation of koi herpesvirus (KHV) and of viral haemorrhagic septicaemia virus (VHSV). For comparison, the stability of these viral pathogens in similar configurations at various pH values and concentrations of peracetic acid or quicklime, typically used for disin...
TRY plant trait database – enhanced coverage and open accessNARA Subscribed
Plant traits—the morphological, anatomical, physiological, biochemical and phenological characteristics of plants—determine how plants respond to environmental factors, affect other trophic levels, and influence ecosystem properties and their benefits and detriments to people. Plant trait data thus represent the basis for a vast area of research spanning from evolutionary biology, community and functional ecology, to biodivers...
Summary In this work we identified the gene for the tetrathionate‐forming thiosulfate dehydrogenase (TsdA) from the purple sulfur bacterium Allochromatium vinosum by sequence analysis and reverse genetics. The recombinant protein produced in Escherichia coli is a periplasmic, monomeric 25.8 kDa dihaem cytochrome c with an enzyme activity optimum at pH 4. UV‐visible and electron paramagnetic resonance spectroscopy indicate meth...
