The Applicability of Nonlinear Systems Dynamics Chaos Measures to Cardiovascular Physiology Variables [PDF]
, 1991 Three measures of nonlinear chaos (fractal dimension, Approximate Entropy (ApEn), and Lyapunov exponents) were studied as potential measures of cardiovascular condition.

The Clinical Respiratory Journal, Volume 20, Issue 11, November 2026.In this prospective pilot, 21 days of continuous wearable ECG monitoring after hospitalisation for COPD exacerbation detected previously unrecognised, clinically actionable arrhythmias in nine of 18 participants (50%). These findings highlight a potentially important postdischarge surveillance gap and support further evaluation of targeted rhythm ...

Experimental Physiology, Volume 111, Issue 11, Page 5032-5040, 1 November 2026.Abstract Advanced age is the strongest risk factor for Alzheimer's disease and related dementias (ADRDs). Traumatic brain injury (TBI) has also been recognized as a risk factor for ADRD, potentially contributing to an earlier onset of the disease. Thus, elucidating the mechanisms underlying brain ageing and TBI is critical for developing strategies to ...

Does long-term experimental antiorthostasis lead to cardiovascular deconditioning in the rat?
Physiological Research, 2009 Microgravity or simulated microgravity induces acute and chronic cardiovascular responses, whose mechanism is pivotal for understanding of physiological adaptation and pathophysiological consequences. We investigated hemodynamic responses of conscious Wistar rats to 45º head-down tilt (HDT) for 7 days.

DNA DOUBLE STRAND BREAK REPAIR DURING HEAD-DOWN-TILT BEDREST: AGBRESA MEETS RADIATION [PDF]
, 2021 BACKGROUND Radiation and reduced gravity impose a major burden on health and performance during human spaceflight. While radiation increases cancer risk and limits tissue regeneration, reduced gravity predisposes to musculoskeletal and cardiovascular ...
