Backgrounds: Subclinical ketosis can cause greater economic loss due to a lack of clinical symptoms. Objectives: The present study was aimed to design a chemical method for measuring serum ketone bodies in the affected subclinical cows. Methods: Acetoacetate concentrations were measured using a nitroprusside reaction and b-hydroxy butyric acid (BHBA) which was oxidized to acetoacetate using nan...
fluorescence chemical sensors for the highly sensitive and selective determination of pb2+ , hg2+, co2+ and fe3+ ions in aqueous solutions are described. the ion sensing system was prepared by incorporating lipophilic ligand (l) as a neutral ion-selective fluoroionophore in the plasticized pvc membrane containing sodium tetraphenylborate or potasium tetrakis (p-chlorophenyl) borate as a liphoph...
