Lake Geneva pollution by micropollutants – a review of 40 years of study. – Lake Geneva drains a watershed of about 8000 km2, subject to anthropogenic pressures due to a large population, agriculture, and industries. Contaminants released by these activiti ...
Aging is characterized by a general decline in cellular function, which ultimately will affect whole body homeostasis. Although DNA damage and oxidative stress all contribute to aging, metabolic dysfunction is a common hallmark of aging at least in inverte ...
Oxylipins are metabolites which are derived from the oxidative fragmentation of polyunsaturated fatty acids. These metabolites play central roles in plant hormonal regulation and defense. Here we survey the production of volatile oxylipins in bryophytes an ...
We set up a survey involving comprehensive chemical analyses of phytoplankton and the simultaneous monitoring of the reproductive response of Calanus helgolandicus. Hatching success and larvae development of C helgolandicus were monitored weekly with femal ...
After wounding, the moss Physcomitrella patens emits fatty acid derived volatiles like octenal, octenols and (2E)-nonenal. Flowering plants produce nonenal from C18-fatty acids via lipoxygenase and hydroperoxide lyase reactions, but the moss exploits the C ...
The consequence of activating the nuclear hormone receptor, peroxisome proliferator-activated receptor gamma (PPARgamma), which coordinates adipocyte differentiation, validates the concept, 'you are what you eat'. Excessive caloric intake leads to fat form ...
Institut fur Pflanzengenetik und Kulturpflanzenforschung (IPK), Corrensstr. 3, D-06466 Gatersleben, Germany. A complex mixture of fatty acid-derived aldehydes, ketones, and alcohols is released upon wounding of the moss Physcomitrella patens. To investigat ...
The nutritional value of diatoms for grazers has been frequently addressed in experiments. However, little is known about the effects of culture conditions on the quality of algae as food for higher trophic levels. We examined the fatty acid composition of ...
The low-density lipoprotein receptor-related protein LRP1 is a cell surface receptor with functions in diverse physiological pathways, including lipid metabolism. Here we show that LRP1-deficient fibroblasts accumulate high levels of intracellular choleste ...
A rapid transformation of eicosapentaenoic acid is initiated upon disintegration of cells of the marine diatom Stephanopyxis turris. In contrast to any other fatty acid cleaving activity known, this diatom releases a blend of chlorinated C8-hydrocarbons in ...
