Spatial oxygen heterogeneity in a Hediste diversicolor irrigated burrow [PDF]
The heterogeneity of oxygen distribution in a Hediste diversicolor burrow environment was investigated in a laboratory experiment using a 6-mm thick tank equipped with oxygen planar optodes. The twodimensional oxygen distribution in a complete burrow was

This review focuses on the role of autophagy and mitophagy in maintaining pancreatic β‐cell function and homeostasis. We discuss how genetic defects affecting these pathways contribute to the development of type 1, type 2, monogenic, and gestational diabetes. We further explore their potential as therapeutic targets. Created in BioRender.

Feedback control of oxygen uptake during treadmill exercise [PDF]
Regulation of exercise intensity is important for aerobic training and for exercise testing. Automatic control of oxygen uptake therefore has potential for use in exercise prescription and in tests to establish markers of cardiopulmonary status.

Obesity raises blood levels of PAI‐1, a protein linked to metabolic dysfunction‐associated steatotic liver disease in people with obesity. In female mice fed a high‐fat diet, partially lowering PAI‐1 led to smaller subcutaneous fat cells and lower liver cholesterol, without changing body weight or insulin sensitivity.

Can greater muscularity in larger individuals resolve the 3/4 power-law controversy when modelling maximum oxygen uptake? [PDF]
BACKGROUND: The power function relationship, MR = a.m(b), between metabolic rate (MR) and body mass m has been the source of much controversy amongst biologists for many years. Various studies have reported mass exponents (b) greater than the anticipated

The effects of temperature on oxygen uptake and nutrient flux in sediment inhabited by molluscs
Benthic invertebrates play important roles in oxygen uptake and nutrient cycling in the benthic boundary layer. Temperature is an important factor that influences both invertebrate activity and the effects of the bioturbation on biogeochemistry.

Encapsulins are protein nanocompartments that play an important role in iron storage. In the Myxococcus xanthus encapsulin system, two cargo proteins called EncB and EncC contribute to iron mineralization. Here, we show that EncB and EncC generate iron‐containing minerals with distinct chemical compositions, suggesting that the composition of stored ...

Use of the 6-minute walk/run test to predict peak oxygen uptake in adolescents
This study aimed to create an equation to predict peak oxygen uptake from data of the 6-minute walk/run test and demographic and anthropometric variables in adolescents. The results of the 6-minute walk/run (6WRT), peak oxygen uptake, height, body weight

Structural and biochemical analysis of a B12 superbinder
BtuG proteins are vitamin B12 scavengers in Bacteroides thetaiotaomicron, a dominant human gut bacterium. We present crystal structures of three BtuG homologs bound to cobalamin and its precursor cobinamide, revealing picomolar binding affinities, among the highest known for any natural protein.
