Partial exposure of single ventricular myocytes to membrane-permeant weak acids or bases, using a dual-microperfusion technique, generates large and stable intracellular pH (pHi) gradients. In this study, we have investigated the feasibility of using the technique to estimate junctional proton permeability. This was done by recording the pHi gradient developed across the junctional region of a ...

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...
