Microscopic description of acid–base equilibrium [PDF]

Proceedings of the National Academy of Sciences of the United States of America, 2019
Significance Acid–base reactions are among the most important chemical processes. Yet we lack a simple way of describing this class of reactions as a function of the atomic coordinates. In fact, once dissolved in water,

Temporal inversion of the acid-base equilibrium in newborns: an observational study [PDF]

PeerJ, 2021
Background A considerable fraction of newborn infants experience hypoxia-ischaemia and metabolic acidosis at birth. However, little is known regarding the biological response of newborn infants to the pH drift from the physiological equilibrium.

The Acid-Base/Deprotonation Equilibrium Can Be Studied with a MicroScale Thermophoresis (MST)

Molecules, 2022
MicroScale thermophoresis (MST) is a rapidly developing bioanalytical technique used routinely for the examination of ligand-target affinity. It has never been used so far for the analysis of acid-base dissociation and the determination of pKa constant ...

Acid-base abnormalities and liver dysfunction

Annals of Hepatology, 2022
In addition to the kidneys and lungs, the liver also plays an important role in the regulation of the Acid-Base Equilibrium (ABE). The involvement of the liver in the regulation of ABE is crucial because of its role in lactic acid metabolism, urea ...

Physiological variables of the “metabolic component” of acid-base balance and mortality in intensive care patients

Revista de la Facultad de Medicina, 2022
Introduction: Metabolic acidosis is a frequent pathophysiological condition in critically ill patients. It can be assessed using different physiological variables, but their prognostic value has not yet been well established.
