A grid model for vertical correction of precipitable water vapor over the Chinese mainland and surrounding areas using random forest [PDF]

open access: yesGeoscientific Model Development
Various ground-based observing techniques provide precipitable water vapor (PWV) products with different spatial resolutions. To effectively integrate these products, especially in terms of vertical orientation, spatial interpolation is essential.

Identification of the individual cardiac contraction threshold during high‐frame‐rate stress echocardiography

open access: yesExperimental Physiology, EarlyView.
Abstract The clinical assessment of cardiovascular function during exercise using stress echocardiography is essential for accurate cardiac diagnosis. However, normal limitations of cardiac deformation responses to increasing physical exertion remain poorly understood.

ZNF384‐Driven Fibulin‐1 Exacerbates Vascular Stiffness via TGF‐β/Smad3‐Mediated Senescence and Fibrosis

open access: yesThe FASEB Journal, Volume 40, Issue 6, 31 March 2026.
This article elucidates the regulatory molecular mechanisms of Fibulin‐1 (Fbln1) in vascular stiffness and explores potential therapeutic interventions. Zinc Finger Protein 384 (ZNF384) binds to the Fbln1 promoter, driving its expression. Fbln1 activates the TGF‐β/Smad3 axis, promoting vascular smooth muscle cell (VSMC) senescence and collagen ...

Associations Between the Severity of Obstructive Sleep Apnea and Arterial Stiffness Estimated by Pulse Wave Velocity Assessment: A Cross‐Sectional Study

open access: yesHealth Science Reports, Volume 9, Issue 3, March 2026.
ABSTRACT Background and Aims Obstructive sleep apnea (OSA) is a prevalent sleep disorder linked to cardiovascular diseases and is highly prevalent, especially in the elderly population. This study aimed to investigate the association between OSA severity and arterial stiffness, as measured by pulse wave velocity (PWV), in patients with moderate to ...

3.5 HEART RATE DEPENDENCE OF REGIONAL AND LOCAL AORTIC PULSE WAVE VELOCITY IN RATS AS A FUNCTION OF BLOOD PRESSURE

open access: yesArtery Research, 2017
Background: Pulse wave velocity (PWV) is quantified by time difference of arrival of the blood pressure (BP) wave at two sites along the arterial bed (transit time; TT-PWV), or by combining measured arterial pressure and diameter using the Bramwell-Hill ...

Modifiable risk factors for increased arterial stiffness in outpatient nephrology. [PDF]

open access: yesPLoS ONE, 2015
Arterial stiffness, as measured by pulse wave velocity (PWV), is an independent predictor of cardiovascular events and mortality. Arterial stiffness increases with age.

2.5 AORTIC-BRACHIAL STIFFNESS MISMATCH AND MORTALITY IN DIALYSIS PATIENTS

open access: yesArtery Research, 2013
Objective. We have shown that regression of brachial stiffness is inversely related to aortic stiffness in dialysis patients. In this study, we sequentially examine the impact of aortic stiffness, brachial stiffness and aortic-brachial stiffness mismatch
