Physics lecture is Nov. 16 Berislav Momcilovic from the Institute for Medical Research and Occupational Health in Zagreb, Croatia, will discuss "Idiorrhythmic Dose Rate Feeding of Non-Energetic Nutrients" Friday, Nov. 16, in 211 Witmer Hall. The current dose-response experimental model was introduced into nutrition from the physical sciences. However, that model does not take into account that we are fed neither continuously nor that the diet is not always the same. Since we are taking our food as meals, and the content of such diet varies from meal to meal, the new idiorrhythmic experimental model offers the study of the dose-rate in nutrition. The physiological response to such idiorrhythmic dose-rate feeding with non-energetic nutrient (zinc) was different from when animals were fed a constant diet. Indeed, the efficiency of the absorption is not a constant, but depends upon the availability of a particular non-energetic nutrient like vitamins and trace elements. Moreover, idiorrhythmic dose rate feeding may act like a natural synchronizer to the cell activity of the body, and hence offers new possibilities in therapeutic pharmacology. -- Connie Cicha, Secretary, Physics, connie_cicha@und.nodak.edu, 701-777-2911
