Pregnancy toxemia was induced in nine pregnant goat does with twins by the stress of fasting with access to water in late pregnancy to investigate the effect of pregnancy toxemia on immunoglobulins (IgA, IgM, and IgG), cortisol, insulin, thyroid, and growth hormones and their correlations with the plasma levels of glucose and beta-Hydroxybutyrate. Plasma samples were collected at 0, 12, 24, 36,...

Using R-beta-[1-(11)C]hydroxybutyrate and positron emission tomography, we studied the effect of acute hyperketonemia (range 0.7-1.7 micromol/ml) on cerebral ketone body utilization in six nondiabetic subjects and six insulin-dependent diabetes mellitus (IDDM) patients with average metabolic control (HbA(1c) = 8.1 +/- 1.7%). An infusion of unlabeled R-beta-hydroxybutyrate was started 1 h before...

D-beta-hydroxybutyrate, the principal "ketone" body in starving man, displaces glucose as the predominating fuel for brain, decreasing the need for glucose synthesis in liver (and kidney) and accordingly spares its precursor, muscle-derived amino acids. Thus normal 70 kg. man survives 2-3 months of starvation instead of several weeks, and obese man many months to over a year. Without this metab...

The metabolic effects of a phlorizin-induced drainage of glucose were studied in six lactating ewes with or without peroral alanine drenches in a study of crossover design. Phlorizin gave rise to a small, but significant, elevation of plasma beta-hydroxybutyrate. The plasma level of alanine decreased by about 30% due to the phlorizin injections and alanine was negatively correlated to beta-hydr...

Abstract Background and Aims A dysregulated energy metabolism is a key feature of Autosomal Dominant Polycystic Kidney Disease (ADPKD), characterized by cystic cells being dependent on glucose poorly able to use other sources such as ketone bodies. Besides providing energy, bodies, especially beta-hydroxybutyrate, can act signaling metabolites reduce inflammation oxidative stress. In experiment...

beta-hydroxybutyrate and acetoacetate as well as lactate and pyruvate are intermediary metabolites normally present in blood. The beta-hydroxybutyrate/acetoacetate ratio is an expression of the mitochondrial oxido-reduction state. This ketone body ratio can provide a clue to diagnosis and metabolic status in congenital errors of the electron transport chain and pyruvate metabolism. The standard...

Methyloligella halotolerans С2T is a moderate halophilic obligate methylotroph, accumulating ultra-high-molecular-weight poly-3-hydroxybutyrate (up to 8 to 10 MDa) from methanol. Here we report a draft genome and annotation of Methyloligella halotolerans C2T (VKM B-2706T = CCUG 61687T = DSM 25045T).
