Reducing Respiratory Artifacts in Heart Rate Variability during Functional Food Intake Using ECG‐Derived Respiration

IEEJ Transactions on Electrical and Electronic Engineering, EarlyView.
Heart rate variability (HRV) has been analyzed to assess the effects of food on autonomic nervous activity, but HRV is reportedly influenced by respiration. Reducing respiratory artifacts in HRV analysis requires respiratory signals. In this study, we estimated respiratory signals from electrocardiogram (ECG), compared these signals with actual ...

Effect of Social Rank on Gut Microbes and Their Metabolites of Greater Long‐Tailed Hamsters (Tscherskia triton)

Integrative Zoology, EarlyView.
Social rank in greater long‐tailed hamsters (Tscherskia triton) shapes gut microbiota composition and metabolite profiles. Dominant males exhibit a “high‐vigilance, metabolically activated” phenotype, with elevated aggression and specific gut microbiota enriched in energy‐harvesting taxa and fecal queuine.
