SFB 299: Project B3.1 - Spatially explicit modelling of phytodiversity in cultural landscapes: model application, adaptation and extension (Project)
...Trade-offs between various landscape functions (e.g., economic and ecological measures) are of special interest in agricultural landscape research. ...In this context, we consider the spatio-temporal patterns of different land-use systems (cultivation, grassland, fallow) as well as abiotic site conditions and socio-economic variables; i.e. the most important driving forces of phytodiversity. The emphasis is laid on compositional aspects of phytodiversity and their measures (e.g. plant species richness, composition and abundance), but we consider structural and functional components of diversity as well....

Flavour compounds in e-liquids - toxicological assessment with relevant in vitro lung models (air-liquid interface) (Project)
...The aim of this in vitro study was the toxicity assessment of three commonly used flavour compounds in e-liquids. Therefore, relevant lung models (16hbe14o and A549) were exposed at the air-liquid interface. The e-liquids were freshly prepared in the lab, containing only one flavour compound in order to being able to assess the toxic properties of the specific flavour compounds and to compair to each other. The e-liquids were aerosolized using an extended automated exposure station and the freshly generated aersosol was guided over the cells. ...

The role of endocrine active substances and hormone receptors for centrosome amplification-induced chromosomal instability in colorectal cancer (Project)
...Thereby, the identification and characterization of the mode-of-action of EAS regarding cell proliferation, does not only provide important implications for human health risks(e.g. EAS-induced colorectal cancer), but does also allow the derivation of endpoints important for the development of in vitro alternative methods with respect to EAS-identification (e.g. an EAS-induced centrosome amplification). ...Our preliminary work indicates an important role for GPER1/GPR30 in EAS-mediated centrosome amplification. Therefore, the next step is to investigate whether other EAS-dependent lesions, such as chromosome maldistribution and centrosomal aberrations (structural and expression levels), depend on GPER1/GPR30. Last but not least, we want to investigate whether natural and xenoestrogens induce cancer-associated adverse effects, such as increased cellular migration and invasion or cancer-like tumor growth, and whether this depends on GPER1/GPR30 and the downstream signaling cascade....

Improve animal welfare at slaughter pigs drifted through redesign of the CO2 anesthesia (Project)
...So far, the swine slaughter of animals before the separation unit input in the gondolas of the CO2-stunning equipment was necessary because the pod opening was on the short side. Meanwhile, CO2 systems are available, where a group of pigs at the same time spent by a drive gear next to the plant on the wide side of the gondola. As an alternative to moving the road to drive to be rebuilt in the way of this plan: an old plant that is placed instead of the new CO2 stunning gondola built by 90 °. These will include a functional solution for the conversion of slaughterhouses with the spatial and structural conditions for CO2-old plants on wildlife-friendly plants with CO2 gruppenweisem unit input into the anesthesia system will be tested in practice. ...

Continuation of the method development for detection of Alaria alata mesocercariae (Project)
...In the course of investigations of the current to 31 August 2010 Research Project 2808HS012 - Studies on the prevalence of Duncker'schen muscle leech in wild animal populations showed that the currently available official parasitological methods (for trichinosis) are not suitable for reliable detection of Duncker '. between leech muscle in wild boar is against this background is now a need to clarify the following: a) Development and validation of a reliable detection method for the Duncker'schen muscle ule. Depending on c) the detection method is to check its suitability as a rapid method for the official investigation into large-scale field tests. b) to clarify the frequency of occurrence of the virus in wild animal populations, especially the wild pig population, use a reliable detection method. For this purpose the collection of information is necessary, especially in regions where the first cases have already occurred. c) evaluating the relevance of the pathogen for human health because of the prevalence data compiled. ...

Actual and potential recreation value of forests in Germany (Project)
...This provides for determining an upper limit of the potential WTP for forest visits (and thus, of the recreation value of the forests), which might be attainable e.g. by specific recreation facilities or by more nature oriented forest management. ...Data were collected by 1.011 personal interviews from a representative population sample. Additionally 1.049 answers from an internet panel survey were available....

Reduced tillage and green manures for sustainable organic cropping systems (TILMAN-ORG). Subproject: Improved Nutrient Management in Reduced Tillage Systems by Use of Green Manures and Appropriate Off-Farm Inputs (Project)
...The major task of WIZ will be to examine the response of soil C and N to both leguminous and non-leguminous green manures incorporated with different intensity and timing of soil tillage. ...WIZ will share its experiences in from one long-term trial and one mid-term trial on reduced tillage and thereby contribute to the state-of-the-art analysis of WP2. Furthermore, WIZ will contribute to the refinement of methods for soil and plant analyses by supplying data from samplings using well-defined methods for the cross validation done within WP3....

Identification of molecular markers of effect of toxicologically relevant compounds to support human biomonitoring (Project)
...These are frequently consumed together, e.g. with grilled meat. Genotoxic compounds of different classes are formed as process contaminants during food preparation, e.g. nitrosamines, heterocyclic aromatic amines, or polycyclic aromatic hydrocarbons. ...Pyrrolizidine alkaloids are also liver toxic. Aflatoxin B1 is a well-known liver tumor-inducing mycotoxin produced by Aspergillus flavus, a fungus preferentially found on nuts. ...

Role of fungal denitrification for N2O fluxes from soils (Project)
...A variety of soil fungi has been proven to produce N2O via denitrification. However, the importance of soil fungi for denitrification and N2O emission from soils is not clear. ...Recently, 15N site preference (SP = difference in 15N abundance of the central and peripheral N positions in the linear N2O molecule) has been proposed to estimate the fraction of fungal N2O using an isotope endmember mixing approach (IEM). This method assumes that SP of emitted N2O results from the fraction of fungal N2O and from the SP endmember signatures of fungal denitrification and of other N2O sources. ...
