Metamorphic or Igneous Zircon? Classification Through Rare Earth Elements, Machine Learning and Logistic Regression

open access: yesJournal of Metamorphic Geology, EarlyView.
ABSTRACT Zircon is a common, highly refractory accessory mineral found in sedimentary, igneous and metamorphic rocks that forms through various processes (e.g., magmatic, hydrothermal, metamorphic growth and recrystallization). Trace element compositions of detrital zircon have been widely applied to understanding tectonic processes and continental ...

Body Composition, Physical Activity and Energy Requirements Estimated Using Two Isotopic Methods in Old and Adult Beagle Dogs

open access: yesJournal of Animal Physiology and Animal Nutrition, EarlyView.
ABSTRACT Energy requirements (ER) are known to decline as dogs age into the senior stage. However, the implications of body composition and physical activity (PA) on this parameter remain poorly investigated. The aim of this study was to evaluate ER, body composition, water turnover rate (WTR), and voluntary PA by triaxial accelerometers in adults (5.2

Metabolic Adaptations to Weight Loss in Obese Senior Dogs: Effects on Energy Expenditure, Protein Turnover, and Voluntary Physical Activity

open access: yesJournal of Animal Physiology and Animal Nutrition, EarlyView.
ABSTRACT Implications of obesity and weight loss (WL) for energy and protein metabolism are not fully understood, particularly in senior dogs. This study evaluated changes in body composition, energy expenditure (EE), protein turnover (PT), and voluntary physical activity (VPA) in senior dogs in maintenance and after 10% and 20% WL.

Systemic, Lifestyle and Environmental Modifying Factors in the Pathogenesis of Periodontitis

open access: yesJournal of Periodontal Research, EarlyView.
A variety of impacting factors in the pathogenesis of periodontitis exist, including systemic, lifestyle, and environmental factors. This review highlights the manifold mechanistic aspects of the link between the pathogenesis of periodontitis, addressing these numerous factors to supplement the long‐standing knowledge of the progression of the disease.

Characterisation of sleep apneas and respiratory circuitry in mice lacking CDKL5

open access: yesJournal of Sleep Research, Volume 34, Issue 2, April 2025.
Summary CDKL5 deficiency disorder is a rare genetic disease caused by mutations in the CDKL5 gene. Central apneas during wakefulness have been reported in patients with CDKL5 deficiency disorder. Studies on CDKL5‐knockout mice, a CDKL5 deficiency disorder model, reported sleep apneas, but it is still unclear whether these events are central (central ...
