Ketone body kinetics in humans: the effects of insulin-dependent diabetes, obesity, and starvation.

Journal of Lipid Research, 1984
The kinetics of acetoacetate (A) and beta-hydroxybutyrate (B) have been studied following the injection as a pulse or continued infusion of [3-14C]acetoacetate (A*) or [14C]beta-hydroxybutyrate (B*) into six newly diagnosed, untreated, ketotic diabetic ...

The NADPH oxidase NOX4 regulates redox and metabolic homeostasis preventing HCC progression

Hepatology, EarlyView., 2022
Loss of NOX4 in HCC tumor cells induces metabolic reprogramming in a Nrf2/MYC‐dependent manner to promote HCC progression. Abstract Background and Aims The NADPH oxidase NOX4 plays a tumor‐suppressor function in HCC. Silencing NOX4 confers higher proliferative and migratory capacity to HCC cells and increases their in vivo tumorigenic potential in ...

Method comparison of beta‐hydroxybutyrate point‐of‐care testing to serum in healthy children

JIMD Reports, 2021
Ketone production is a physiological phenomenon that occurs to avoid irreversible neurological damage from hypoglycemia, thereby serving as a marker of metabolic stress.

Estudo das propriedades e biodegradabilidade de blendas de poliéster/amido submetidas ao ataque microbiano Study of the properties and biodegradability of polyester/starch blends submitted to microbial attack

Química Nova, 2007
This work deals with the biodegradation of blends of poly(beta-hydroxybutyrate)/starch and poly(beta-hydroxybutyrate-co-hydroxyvalerate)/starch. The blends were obtained by evaporation of the solvent in the mixture of the polymers in chloroform.

Ingestion of an exogenous ketone monoester improves the glycemic response during oral glucose tolerance test in individuals with impaired glucose tolerance: A cross‐over randomized trial

Journal of Diabetes Investigation, 2021
Aims/Introduction As a low‐carbohydrate diet and the use of sodium–glucose transporter‐2 inhibitors are both known to increase D‐beta‐hydroxybutyrate levels, the effect of these levels on glucose metabolism has attracted attention.

Ketone Body Metabolism in the Ischemic Heart

Frontiers in Cardiovascular Medicine, 2021
Ketone bodies have been identified as an important, alternative fuel source in heart failure. In addition, the use of ketone bodies as a fuel source has been suggested to be a potential ergogenic aid for endurance exercise performance.

Nile blue A as a fluorescent stain for poly-beta-hydroxybutyrate [PDF]

Applied and Environmental Microbiology, 1982
Poly-beta-hydroxybutyrate granules exhibited a strong orange fluorescence when stained with Nile blue A. Heat-fixed cells were treated with 1% Nile blue A for 10 min and were observed at an excitation wavelength of 460 nm. Glycogen and polyphosphate did not stain.

Determination of 14C radioactivity in ketone bodies: a new, simplified method and its validation.

Journal of Lipid Research, 1980
A rapid and reproducible method for the assay of 14C radioactivity in ketone bodies is described, based on the heat lability of acetoacetate and the ability of beta-hydroxybutyrate to quantitatively bind to and elute from an ion exchange resin. Potential

An open-label, acute clinical trial in adults to assess ketone levels, gastrointestinal tolerability, and sleepiness following consumption of (R)-1,3-butanediol (Avela™)

Frontiers in Physiology, 2023
Introduction: A study was undertaken to determine the acute effects of a beverage made with Avela™ (R)-1,3-butanediol, on blood beta-hydroxybutyrate (BHB) levels (using the Keto-Mojo monitor), gastrointestinal (GI) tolerability (using the modified visual

Functional and Network PHAs via Stereoselective Polymerization and Tailored Post‐Transformation

Angewandte Chemie, EarlyView.
Catalyst‐controlled stereoselective (co)polymerization of functionalized lactones produces vinyl‐, allyl‐, and propargyl‐functionalized PHAs with high syndiotacticity and a broad applicable temperature window, which can be further transformed into crosslinked PHA thermosets, elastic supramolecular networks, and functional grafts.
