Cardiovascular effects of lactate in healthy adults.

Background: Low-volume hypertonic solutions, such as half-molar lactate (LAC), may be a potential treatment used for fluid resuscitation. This study aimed to evaluate the underlying cardiovascular effects and mechanisms of LAC infusion compared to sodium-matched hypertonic sodium chloride (SAL).

Methods: Eight healthy male participants were randomized in a controlled, single-blinded, crossover study.

Cerebral and myocardial kinetics of [C]acetoacetate and [C]β-hydroxybutyrate: A comparative crossover study in healthy rats.

Background: Ketone metabolism has been studied using positron emission tomography (PET) with the radiotracers [C]acetoacetate and [C]β-hydroxybutyrate. However, whether these two radiotracers actually yield equivalent estimates of cerebral and myocardial ketone metabolism has not yet been investigated. This study aimed to investigate and compare the kinetics of both tracers in the brain and heart of healthy rats under varying levels of circulating ketones at baseline and after a single-dose exogenous ketone ester (KE) supplement.

Improving the integration of care for trans adults: ICTA a mixed-methods study.

Background: This research concerns improving the National Health Service health services trans adults need. These include the national specialist Gender Identity Clinics that support people making a medical transition. Not all trans people need to make a medical transition, and transition can take many different paths.

Preparation and Preclinical Characterization of a Simple Ester for Dual Exogenous Supply of Lactate and Beta-hydroxybutyrate.

Elevation of the plasma levels of ()-lactate (Lac) and/or ()-beta-hydroxybutyrate (BHB) occurs naturally in response to strenuous exercise and prolonged fasting, respectively, resulting in millimolar concentrations of these two metabolites. It is increasingly appreciated that Lac and BHB have wide-ranging beneficial physiological effects, suggesting that novel nutritional solutions, compatible with high-level and/or sustained consumption, which allow direct control of plasma levels of Lac and BHB, are of strong interest. In this study, we present a molecular hybrid between ()-lactate and the BHB-precursor ()-1,3-butanediol in the form of a simple ester referred to as .
