Cupiennius salei (Ctenidae) has been extensively studied for many years and is probably the only spider that presently can be considered a model organism for neuro-ethology. The night-active spiders have been shown to predominantly rely on their excellent mechano-sensory systems for courtship and prey capture, whereas vision was assumed to play a minor(More)
For investigations of CO2-stunning of feeder- and slaughter-pigs parameters of behaviour, blood-gas-analyses and electroencephalograms were chosen. The following results were obtained: 1. Blood-gas-analyses proved that the CO2-stunning does not produce unconsciousness due to a lack of oxygen. 2. The criterias of general anaesthesia: unconsciousness,(More)
The aim of this study was to produce in vitro oxidation products of lycopene, which could be possible in vivo metabolites. An oxidation of lycopene with potassium permanganate gave a range of lycopene degradation compounds resulting from the oxidative cleavage of one or two carbon-carbon double bonds. Eleven apo-lycopenals/ones and six apo-carotendials were(More)
Previous studies have shown that an intravenous infusion of dextran sulfate (DXS) causes arterial hypotension via release of bradykinin (BK) and stimulation of bradykinin B2 receptors in pigs. The bradykinin B1 receptor is not physiologically present but its expression can be induced by bacterial lipopolysaccharide (LPS). This study was designed to assess(More)
Five geometrical isomers of lycopene were isolated from a photoisomerized mixture on a semi-preparative C30 column and characterized by UV-vis spectroscopy, mass spectroscopy, and nuclear magnetic resonance (NMR) spectroscopy. 1H NMR and 2D NMR measurements were used to unambiguously assign the double bond configuration of five isomers: (5Z,9'Z)-, (9Z)-,(More)
In this paper preventive liver protective agents for the prophylaxis of hepatopathies due to functional stress, and curative protective agents for therapy of existing liver damage are distinguished. Preventive liver protective agents are key substances in the metabolism of proteins, carbohydrates, lipids, and sulfur. For curative liver protective agents,(More)
