Wereadwith interest the article byRubino et al. (1). The authors suggest treatment withmetabolic surgery after conservative therapy does not reach individual diabetes targets in patients with BMI .30 kg/m. They recommend sodium–glucose cotransporter 2 (SGLT2) inhibitors as suitable drugs, among others, for early postoperative diabetes management due to their low risk of inducing hypoglycemia. T...

Inhibition of gluconeogenesis with 3-mercaptopicolinate in suckling newborn rats caused a fall in blood [glucose], but no change in their high plasma [free fatty acid] and blood [ketone bodies]. Active gluconeogenesis seems to be more important than sparing of glucose by high concentrations of fat-derived substrates for the maintenance of normal blood [glucose] in suckling newborn rats.

Inhibition of fatty acid oxidation with pent-4-enoate in suckling newborn rats caused a fall in blood [glucose] and blood [ketone bodies] and inhibition of gluconeogenesis from lactate. Glucose utilization was not increased in newborn rats injected with pent-4-enoate. Active fatty acid oxidation appears to be essential to support gluconeogenesis and to maintain normal blood [glucose] in sucklin...

Vesicular glutamate transporters (VGLUTs) load glutamate into synaptic vesicles. In this issue of Neuron, Juge et al. report that ketone bodies compete with chloride-dependent activation of VGLUTs, leading to suppression of glutamate release and seizures. These findings provide a surprising explanation for the efficacy of the ketogenic diet in controlling epilepsy.

Subclinical ketosis is a metabolic disorder in high-producing dairy cattle that can be detected by ketone bodies in milk: acetone (Ac), acetoacetate (AcAc), and beta-hydroxybutyrate (BHBA). Fourier transform infrared (FTIR) spectrometry is to a growing extent used for determination of milk constituents in milk recording, but as yet there is no calibration for ketone bodies available. The object...

The effects of vasopressin on the metabolism of starved rats were investigated by using a constant-infusion regimen (50 pmol/kg body wt. per min, after an initial loading dose of 150 pmol/kg body wt.). 2. Blood ketone bodies decreased by 50% in 10 min, and this was accompanied by a 60% decrease in the plasma non-esterified fatty acids. 3. Blood glucose increased by 0.9 mM within 5 min and decre...
