Impact of Heart Rate Fragmentation on the Assessment of Heart Rate Variability
Applied Sciences, 2020 Heart rate fragmentation (HRF) is a type of sinoatrial instability characterized by frequent (often every beat) appearance of inflection in the R-R interval time series, despite the electrocardiograms appearing to be sinus rhythm.

Decreased Heart Rate Variability in COVID-19
Intensive Care Research, 2022 Purpose Coronavirus disease 2019 (COVID-19) is caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), which primarily infects the lower airways and binds to angiotensin-converting enzyme 2 (ACE2) on alveolar epithelial cells.

Influence of a 100-mile ultramarathon on heart rate and heart rate variability
BMJ Open Sport & Exercise Medicine, 2021 Aims This study aimed to investigate the impact of an ultramarathon (UM) with a distance of 100 miles on heart rate (HR) and heart rate variability (HRV).Methods 28 runners (25 men and 3 women) underwent 24-hour Holter ECG monitoring 1 week before the UM,

Molecular Oncology, Volume 20, Issue 6, Page 1513-1534, June 2026.Nanosecond infrared laser (NIRL) low‐volume sampling combined with shotgun lipidomics uncovers distinct lipidome alterations in oropharyngeal squamous cell carcinoma (OPSCC) of the palatine tonsil. Several lipid species consistently differentiate tumor from healthy tissue, highlighting their potential as diagnostic markers.

Influence of a neck compression collar on cerebrovascular and autonomic function in men and women [PDF]
, 2019 Objective Neck compression collars have been proposed to reduce injury to the brain caused by head impacts. Our objective was to test if compression of the carotid artery affected the baroreflex and influenced blood pressure control.

Molecular Oncology, Volume 20, Issue 6, Page 1473-1493, June 2026.This work identified serum proteins associated with pancreatic epithelial neoplasms (PanINs) and early‐stage PDAC. Proteomics screens assessed genetically engineered mice with abundant PanINs, KPC mice (Lox‐STOP‐Lox‐KrasG12D/+ Lox‐STOP‐Lox‐Trp53R172H/+ Pdx1‐Cre) before PDAC development and also early‐stage PDAC patients (n = 31), compared to benign ...

Cardiovascular Consequences of Unfair Pay [PDF]
This paper investigates physiological responses to perceptions of unfair pay. In a simple principal agent experiment agents produce revenue by working on a tedious task. Principals decide how this revenue is allocated between themselves and their agents.

Heart rate recovery after exercise: relations to heart rate variability and complexity
Brazilian Journal of Medical and Biological Research, 2002 Physical exercise is associated with parasympathetic withdrawal and increased sympathetic activity resulting in heart rate increase. The rate of post-exercise cardiodeceleration is used as an index of cardiac vagal reactivation.
