ABSTRACT As breath‐hold divers, marine mammals must coordinate their use of both aerobic and anaerobic metabolism to maximize their time at depth. One indication of the relative reliance between these two energy‐producing systems is the aerobic dive limit (ADL), defined as the dive duration where post‐dive blood lactate concentrations surpass resting ...

Open-flow respirometry under field conditions: How does the airflow through the nest influence our results? [PDF]
Open-flow respirometry is a common method to measure oxygen-uptake as a proxy of energy expenditure of organisms in real-time. Although most often used in the laboratory it has seen increasing application under field conditions.

Passage‐Dependent Size Distributions of Human‐Derived Cells: Implications for Metabolic Assays
Cell size changes with passage. This propagates into size‐dependent functional readouts, such as metabolic assays. ABSTRACT Biological noise is ubiquitous in living systems; yet, it is often neglected in cell‐based experiments, potentially biasing data interpretation.

The pyruvate generator, which causes activation of respiration by extra‐mitochondrial Ca2+, is also present and functional in rat brainstem mitochondria, as it is in other brain regions. This finding is confirmed by experiments with a fully reconstituted malate–aspartate shuttle (MAS).

Sex differences in brain glucose metabolism and Alzheimer's disease risk and progression
Abstract Sex differences are increasingly recognized as central to the biology of Alzheimer's disease (AD), yet the mechanisms through which they shape brain metabolism and disease vulnerability remain incompletely understood. Brain glucose hypometabolism is a core hallmark of AD and emerges decades before clinical decline, but accumulating evidence ...

Novel Approaches for the Application of Mitochondrial Respirometry in Human Studies
Though mitochondrial research has become more prominent in the last forty years, most methodologies to study mitochondria have been focused on cell and animal models.

ABSTRACT Basal and standard metabolic rate (BMR and SMR) are cornerstones of physiological ecology and are assumed to be relatively fixed intrinsic properties of organisms that represent the minimum energy required to sustain life. However, this assumption is conceptually flawed. Many core maintenance processes underlying SMR are temporally partitioned

Abstract The waste activated sludge high‐rate (WASHR) process, developed in our previous study, is used for septic wastewater treatment. This high‐rate contact stabilization pre‐treatment uses typical waste streams found in wastewater treatment plants to reduce a portion of the loadings on the main treatment trains.

We demonstrated that Awaous tajasica performs facultative air breathing under experimental conditions of dissolved oxygen limitation, retaining air bubbles in the buccal cavity during gill ventilation. Morpho‐functional evidence indicates the use of atmospheric oxygen as a respiratory support under conditions of low water oxygenation.

Multimodal Assessment of Kidney Quality During 24‐h of Normothermic Machine Perfusion
Normothermic machine perfusion (NMP) has emerged as a promising tool for assessing kidney quality prior to transplantation; however, reliable biomarkers remain to be established. In this study, thirteen porcine kidneys were perfused for 24 h using an autologous leukocyte‐filtered whole blood‐based perfusate applying urine recirculation.
