Effect of obstructive sleep apnea on the response to hypertension therapy

open access: yesClinical and Experimental Hypertension, 2017
Obstructive sleep apnea (OSA) often precedes cardiovascular disease, partly due to treatment resistant hypertension. The nocturnal apneas of OSA trigger increased sympathetic nervous discharge during both sleep and wakefulness.

The Infrared Astronomical Characteristics of Roque de los Muchachos Observatory: precipitable water vapor statistics [PDF]

open access: yes, 2010
The atmospheric water vapor content above the Roque de los Muchachos Observatory (ORM) obtained from Global Positioning Systems (GPS) is presented. GPS measurements have been evaluated by comparison with 940nm-radiometer observations.

Silicon photonics-based laser Doppler vibrometer array for carotid-femoral pulse wave velocity (PWV) measurement.

open access: yesBiomedical Optics Express, 2020
Pulse wave velocity (PWV) is a reference measure for aortic stiffness, itself an important biomarker of cardiovascular risk. To enable low-cost and easy-to-use PWV measurement devices that can be used in routine clinical practice, we have designed ...

Alterations in vascular function in primary aldosteronism - a cardiovascular magnetic resonance imaging study [PDF]

open access: yes, 2014
Introduction: Excess aldosterone is associated with increased cardiovascular risk. Aldosterone has a permissive effect on vascular fibrosis. Cardiovascular magnetic resonance imaging (CMR) allows study of vascular function by measuring aortic ...

An Empirical Grid Model for Precipitable Water Vapor

open access: yesRemote Sensing, 2022
Atmospheric precipitable water vapor (PWV) is a key variable for weather forecast and climate research. Various techniques (e.g., radiosondes, global navigation satellite system, satellite remote sensing and reanalysis products by data assimilation) can ...

A prospective study on pulse wave velocity (PWV) and response to anti-hypertensive treatments: PWV determines BP control.

open access: yesInternational journal of cardiology, 2015
Recent data indicate that hypertension is not well controlled in many populations throughout the world. The factors that influence individual response to anti-hypertensive treatment need to be clarified. Pulse wave velocity (PWV), as a marker of arterial stiffness, has been demonstrated to have important relationships with BP progression; however ...

Directly Observing Momentum Transfer in Twin-Slit "Which-Way" Experiments [PDF]

open access: yes, 2003
Is the destruction of interference by a which-way measurement due to a random momentum transfer $\wp\agt\hbar/s$, with $s$ the slit separation? The weak-valued probability distribution $P_{\rm wv}(\wp)$, which is {\em directly observable}, provides a ...

Comparison of Carotid‐Femoral and Brachial‐Ankle Pulse‐Wave Velocity in Association With Target Organ Damage in the Community‐Dwelling Elderly Chinese: The Northern Shanghai Study

open access: yesJournal of the American Heart Association: Cardiovascular and Cerebrovascular Disease, 2017
BackgroundCarotid‐femoral pulse‐wave velocity (cf‐PWV) and brachial‐ankle PWV (ba‐PWV) are the 2 most frequently applied PWV measurements. However, little is known about the comparison of hypertensive target organ damage (TOD) with cf‐PWV and ba‐PWV ...
