Animal shorts

Other iboga alkaloids besides ibogaine (tabernanthine, R- and S-coronaridine, R- and S-ibogamine, and desethylcoronaridine) decrease morphine and cocaine intake in animals shortly after administration, and in some cases one day after administration (Click et al. 1994). R-ibogamine was the most consistent in this effect, reducing intake for several days after a single injection. 

In the absence of definitive human data, risk assessment may have to depend on the results of cancer bioassays in laboratory animals, short-term tests, or other experimental methods. Hence the following issues must be addressed under such circumstances the ability of the test system to predict risks for man (quantitatively as well as qualitatively) the reproducibility of test results the influence of species differences in pharmacokinetics, metabolism, homeostasis, repair rates, life span, organ sensitivity, and baseline cancer rates extrapolation across dose and dose rates, and routes of exposure the significance of benign tumors fitting models to the data in order to characterize dose-incidence relationships and the significance of negative results. 

Alternative models (transgenic animals) short term ass ays /supportive models (activity often limited to one or a few tissues)... 

The second IPCS study on in vivo assay systems utilized the two test chemical pairs BP/P and 2AAF/4AAF to evaluate a wide range of whole animal short-term tests for genotoxicity and carcinogenicity. 

This androstenone-stimulated process is completely reversible. Washing out the olfactory epithelium with the soluble form of alkaline phosphatase returned all kinetic characteristics of proteins with alkaline phosphatase activity to the initial level found in the control group of animals. Short-term exposures to androstenone also caused a reversible activation of immobilized alkaline phosphatase. For longer exposures we noted a different type of response to androstenone stimulation. 

Video Meirketing videos come in many forms. Think 60-90-second demo videos, animated shorts, live action commercials, webincir recordings, and presentation recordings, to name a few.
