The carbonic anhydrase II mutant His64Cys was prepared and applied to tethered alkyne/azide cycloaddition reactions. The azide component could be tethered to the enzyme surface through a disulfide bridge, while the alkyne component was reversibly coordinated through a sulfonamide anchor to the zinc ion in the original catalytic center of the enzyme. The(More)
In order to study mechanisms in ruminants responsible for glucocorticoid-induced hyperglycemia the effects of a single intravenous dose of a glucocorticoid on energy metabolism were investigated by measuring plasma levels of glucose, lactate, free fatty acids (FFA), 3-hydroxybutyrate (3-HOB) and acetoacetate (AcAc). Experiments were performed on four(More)
Following on from clinical observations which point to severe metabolic disturbances in association with acute Eperythrozoon (E.) suis infection, the parameters of acid-base balance (pO2, pCO2, pH, actual bicarbonate, standard bicarbonate, base excess) as well as the glucose-, lactate- and pyruvate levels, were measured in venous blood during the course of(More)
In the present study glucose kinetic parameters like pool size, distribution volume and rates of total entry and irreversible loss were determined in four castrated male African pygmy goats during hyperglycemia induced by an intravenous glucocorticoid injection (0.25 mg dexamethasone = DXM per kg body weight). Experiments were done at two different(More)
