Article Abstract

The UAB Nathan Shock Center focuses on comparative energetics and aging. Energetics, as defined for this purpose, encompasses the causes, mechanisms, and consequences of the acquisition, storage, and use of metabolizable energy. Comparative energetics is the study of metabolic processes at multiple scales and across multiple species as it relates to health and aging. The link between energetics and aging is increasingly understood in terms of dysregulated mitochondrial function, altered metabolic signaling, and aberrant nutrient responsiveness with increasing age. The center offers world-class expertise in comprehensive, integrated energetic assessment and analysis from the level of the organelle to the organism and across species from the size of worms to rats as well as state-of-the-art data analytics. The range of services offered by our three research cores, (1) The Organismal Energetics Core, (2) Mitometabolism Core, and (3) Data Analytics Core, is described herein.

Accurately modeling volume-dependent properties of water remains a challenge for density functional theory (DFT), with widely used functionals failing to reproduce key features of the water density isobar, including its shape, density, and temperature of the density maximum. Here, we compare the performance of the RPBE-D3 and vdW-DF-cx functionals using replica exchange molecular dynamics (MD) driven by machine-learned force fields. Our simulations reveal that vdW-DF-cx predicts the water density more accurately than RPBE-D3 and reproduces the isobar closely between 307 and 340 K.

Background: Imeglimin (Ime), the first in a novel class of antidiabetic agents, has potential therapeutic effects on diabetic peripheral neuropathy (DPN). This study aimed to evaluate and compare the effects on cellular metabolic function and reactive oxygen species (ROS) levels in high glucose-treated mouse Schwann cells (SCs), an DPN model, with those of metformin (Met), a conventional antidiabetic agent known for its beneficial effects on DPN. The roles of PPARα and fatty acid-binding proteins 5 and 7 (FABP5 and FABP7), both of which have been implicated in the pathogenesis of DPN, were also investigated.

Optimum Push-off for Uneven Walking Based on the Just-in-Time Strategy: Walking with Interrupted Push-Off is Mechanically Costly.

Department of Biomedical Engineering, Schulich School of engineering, University of Calgary, AB, Canada; Cumming School of Medicine, University of Calgary, AB, Canada.

Using a powered simple walking model (point mass with rigid massless legs), the optimal analytical push-off was derived based on walking speed and step elevation changes. It was observed that higher speeds increased the available push-off to attain greater step-up e.g.

Comparative radiation dose analysis in pediatric high-pitch cardiac CTA using photon-counting versus energy-integrating detector CT.

Pediatr Radiol

September 2025

Department of Radiology, University of Colorado School of Medicine/Department of Pediatric Radiology, Children's Hospital Colorado, 13123 East 16th Avenue, Box 125, Aurora, 80045, Colorado, USA.

Background: Previous studies have shown improved image quality in pediatric cardiac imaging using photon-counting detector CT (PCDCT). However, these studies did not evaluate image quality and radiation dose when utilizing the full spectral capabilities of PCDCT scanners. The full spectral capability of PCDCT scanners allows the generation of the entire array of mono-energetic reconstructions, virtual non-contrast (VNC) images, and iodine maps, which have potential advantages in evaluating complex congenital heart disease.

Metabolic responses to energetic stimuli in female athletes using or not hormonal contraceptives during a high training load period.

J Sports Med Phys Fitness

September 2025

UPR 3533, Laboratory of the Metabolic Adaptations to Exercise under Physiological and Pathological Conditions (AME2P), Clermont Auvergne University, CRNH Auvergne, Clermont-Ferrand, France -

Background: Despite growing interest in women's physiology in exercise sciences, the understanding of female athletes' energy metabolism remains limited. This study aimed to analyze substrate oxidation in response to energetic stimuli in female athletes using or not hormonal contraceptives, and to determine the influence of the estradiol-to-progesterone ratio fluctuations on energy metabolism.

Methods: Body composition (dual-energy X-ray absorptiometry), energy expenditure and substrate oxidation rates (resting, low-intensity walking exercise (4 km/h), and postprandial conditions; indirect calorimetry) were assessed among 32 athletes (23±3 years) during a high-training load period, in athletes using or not hormonal contraceptives (nine and 23, respectively).
