Acclimation of Chlamydomonas reinhardtii cells to low levels of singlet oxygen, produced either by photoreactive chemicals or high light treatment, induces a specific genetic response that strongly increases the tolerance of the algae to subsequent exposure to normally lethal singlet oxygen-producing conditions. The genetic response includes the increased(More)
By means of the official meat inspection of domestic pigs, exceptionally high proportions of livers affected by encapsulated nodules containing whitish to light yellow, viscous to pasty material (“microabscesses”) were detected. The swine had been raised on four different farms, being located in distinct regions of Germany (Brandenburg, Thuringia, Upper(More)
The ketogenic diet (KD), a high-fat low-carbohydrate diet, has shown some efficacy in the treatment of certain types of tumors such as brain tumors and neuroblastoma. These tumors are characterized by the Warburg effect. Because renal cell carcinoma (RCC) presents similar energetic features as neuroblastoma, KD might also be effective in the treatment of(More)
Many community portals allow users to search for events, such as concerts, festivals or other things of interest and to rate them. Especially in the culture domain the users’ impressions of events is based on many factors, such as quality, personal interests, etc. Such factors can be represented using an ontology. The ratings provided by the users of(More)
Galanin and its receptors (GAL1, GAL2, GAL3) modulate a range of neuronal, immune and vascular activities. In vivo administration of SNAP 37889 (1-phenyl-3-[[3-(trifluoromethyl)phenyl]imino]-1H-indol-2-one), a potent small non-peptidergic antagonist of GAL3, was reported to reduce anxiety- and depression-related behavior, ethanol consumption, and(More)
The use of autonomous systems with local planning intelligence permits the optimization of task-processing in flexible production environments. Integration of local planning intelligence into the general task-planning process is necessary if the overall planning process is to be handled productively. For this purpose the coordinating instance distributes(More)
