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.

Microscopic description of acid-base equilibrium. [PDF]

Proc Natl Acad Sci U S A, 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, H

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.

Biochemical Approach of Acid-Base Disturbances

Revista Colombiana de Nefrología, 2023
Background: The current paradigms in arterial blood gas analysis are based on mathematical or physicochemical models that require complex algorithms for interpretation. This leads to avoidance or dislike from health care professionals.

Thermodynamic modelling of mixtures of water, carbon dioxide and hydrogen at high pressure and temperature for hydrothermal CO2 reduction processes

Frontiers in Physics, 2023
In the context of the increasing CO2 emissions and the corresponding environmental problems, CO2 utilization processes that transform CO2 into valuable compounds rather than just capturing and storing it can contribute to the transition to a carbon-free ...
