Evidence exists that butyrate inhibits apoptosis of colon crypt cells in vivo so that less tryptophan from cell debris is available for skatole formation by microbes in the pig colon. In this study, potato starch containing a high proportion of resistant starch was fed to test the hypothesis that increased butyrate formation will occur in the colon and(More)
One of each pair of female sister rats aging 1, 4, 7 or 10 months was exposed during 3 months to 31.5 mg/L Cd (as CdCl2) in its drinking water and sacrificed immediately after Cd exposure together with its untreated sister. Concentrations of Cd, Zn and Cu were measured in the kidneys (medulla and cortex), the liver, the duodenum and the uterus. Furthermore,(More)
Selenium (Se) as essential trace element is supplemented in various compounds to rations of food producing animals. In human nutrition the range between Se requirement and upper level is very small (1:3–5). Hence, food of animal origin may contribute to Se supply of humans, but can also offer high amounts of Se and exceed the Se upper level for humans.(More)
Genotypes of cereal grains, including winter barley (n = 21), maize (n = 27), oats (n = 14), winter rye (n = 22), winter triticale (n = 21) and winter wheat (n = 29), were assayed for their chemical composition and physical characteristics as part of the collaborative research project referred to as GrainUp. Genotypes of one grain species were grown on the(More)
Das stoffliche Geschehen wtthrend der Embryonalentwicklung war lange Zeit der Forschung nahezu unzug~inglieh, trotzdem bereits W. His und F. MIESCH~R die hier vorliegenden Probleme geahnt hatten, Erst die modernen Methoden der Entwicklungsmechanik, der Histochemie and der Zytochemie haben es in den letzten Jahrzehnten mehr und mehr erm6glicht, die chemische(More)
Energy content of feedstuffs has to be determined by animal experiments. For practical purposes energy content of feeds was predicted by data on in vivo digestibility of nutrients, in vitro digestibility and different chemical parameters. Especially chemical and in vitro parameters were used in different combinations as predictors. The accuracy of such(More)

For the aromatic molecules benzene, naphthalene, and anthracene a relation is found between dipole moment and dissociation constant of the hydroxy compounds and the carboxylic acids on the one hand and theπ-electron density at the respective carbon atom in the unsubstituted molecule on the other hand. The following statement can be made:—Theπ-electron(More)
