Calcium requirement of growing rabbits.
T HE minimum calcium requirement of growing rabbits has not been determined. In practice dietary calcium levels have been based largely on information gained from other animals. Commercial rabbit diets commonly contain 0.8 to 1.0% calcium. Since the domestic rabbit is extensively used as an experimental animal and is increasingly used as a source of edible meat, particularly in the Los Angeles ...
متن کاملCalcium Requirement for Ethylene-Dependent Responses.
Ethylene, a gaseous plant hormone, plays a role in plant development, defense, and climacteric fruit ripening. Both genetic and biochemical evidence suggest that the response of plants to ethylene is mediated by a specific ethylene receptor. The signal emanating from the receptor-effector complex is then presumably transduced via an unknown cascade pathway. We have used the plant pathogenesis r...
متن کاملCalcium Requirement of Maintenance in Man,*
The demonstration upon laboratory animals by Osborne and Mendel,’ that calcium necessarily occupies a prominent place in the inorganic food supply, and that of McCollum, Simmonds, and Parsons,2 that calcium is one of the limiting fact’ors in a very large proportion of our staple foods, lends added interest to the measurement of the calcium requirement in man and the comparison of the amount of ...
متن کاملOptimum calcium concentration of dialysis fluid for maintenance haemodialysis.
To define the minimum and maximum levels for calcium concentration of dialysis fluid a combination of acute and long-term observations was carried outIn acute experiments the external calcium balance during dialysis was dependent on the gradient between plasma ultrafilterable calcium and dialysis fluid calcium concentration. Changes in plasma calcium during dialysis did not correlate with measu...
متن کاملRequirement for nuclear calcium signaling in Drosophila long-term memory.
Calcium is used throughout evolution as an intracellular signal transducer. In the mammalian central nervous system, calcium mediates the dialogue between the synapse and the nucleus that is required for transcription-dependent persistent neuronal adaptations. A role for nuclear calcium signaling in similar processes in the invertebrate brain has yet to be investigated. Here, we show by in vivo...
