Obesity and sarcopenia affect the metabolite profiles of pet dogs

ABSTRACT Overweight and reduced muscle mass significantly affect canine health, yet their metabolic implications in dogs require further investigation. This study aimed to characterize metabolic alterations associated with overweight, obesity, and reduced muscle mass in dogs. An...

Curve fitting algorithm for multimodal particle size distributions – a theoretical basis

Abstract. Here we detail an open-source curve fitting algorithm for multimodal particle size distributions (MPSDs) and evaluate it against a ten-year dataset of ambient particle size distribution (PSD) measurements collected at Storm Peak Laboratory, a remote mountainous research...

Engineering structured solid amine sorbents from industrial slag-derived nanocomposites for CO2 capture

The demand for shaped/structured sorbents that utilize inorganic support is steadily increasing, as many startups heavily use primary amine-functionalized ion exchange resins. Meanwhile, the cost of sorbents for direct CO2 capture from air is high, and the use of virgin raw mater...

Exploring the hydrogen abstraction pathway in HOM formation from α -pinene photooxidation systems under varying NO conditions

Abstract. Highly oxygenated organic molecules (HOM) are formed via autoxidation during ⚫OH-initiated oxidation of α-pinene. We investigated the relative contributions of OH-addition and hydrogen (H)-abstraction to HOM formation from α-pinene photooxidation under varying nitrogen...

Sexual dimorphism in root exudation mediates belowground neighbor recognition and shapes rhizosphere soil microbial assembly

Summary Sexual dimorphism in physiological traits is a hallmark of dioecious plants, yet whether these differences extend belowground to mediate neighbor recognition and rhizosphere microbiome assembly remains largely unexplored. Using split‐root experiments, 13 C‐pulse labeling,...
