Cerebrovascular pulsatility following long duration spaceflight is associated with changes in pulse pressure and carotid artery stiffness

open access: yesExperimental Physiology, EarlyView.
Abstract Central artery stiffening increases the haemodynamic pulsations transmitted downstream towards target organs, including the brain. While recent evidence suggests that long duration spaceflight is associated with reduced common carotid artery (CCA) distensibility, cerebrovascular pulsatility has not been extensively characterized in astronauts.

Wearable Hyperspectral Photoplethysmography Allows Continuous Monitoring of Exercise‐Induced Hypertension

open access: yesAdvanced Science, Volume 12, Issue 22, June 12, 2025.
A wearable hyperspectral photoplethysmography (HS‐PPG) is reported for continuous blood pressure (BP) monitoring. The HS‐PPG module integrates an ultrathin double‐folded solid immersion grating microspectrometer (DFSIG‐µSPEC), achieving a high spectral resolution of 3.4 nm.

Changes in intraocular pressure after intraocular eye surgery—the influence of measuring technique [PDF]

open access: yesInternational Journal of Ophthalmology, 2019
AIM: To investigate the changes in intraocular pressure (IOP) before and after intraocular surgery measured with Goldmann applanation tonometry (GAT) and pascal dynamic contour tonometry (PDCT), and assessed their agreement.

Effect of a reduction in glomerular filtration rate after nephrectomy on arterial stiffness and central hemodynamics: rationale and design of the EARNEST study [PDF]

open access: yes, 2014
Background: There is strong evidence of an association between chronic kidney disease (CKD) and cardiovascular disease. To date, however, proof that a reduction in glomerular filtration rate (GFR) is a causative factor in cardiovascular disease is ...

The Effect of Advancing Age and Intraocular Pressure Injury on Retinal Ganglion Cell Function and Synaptic Connectivity

open access: yesAging Cell, Volume 24, Issue 6, June 2025.
The effect of advancing age and intraocular pressure injury on retinal ganglion cell function and synaptic connectivity. While young mice modulate their synaptic input to recover retinal ganglion cell function following injury, older mice compensate by altering their action potential threshold and axon initial segment (AIS) length to increase intrinsic

Investigation of ocular surface parameters in dogs with different cephalic conformations using veterinary ocular surface analyzer (OSA‐VET)

open access: yesVeterinary Ophthalmology, Volume 28, Issue 3, Page 605-618, May 2025.
Abstract Objective To compare ocular surface parameters in dogs with different cephalic conformations and evaluate correlations among tests. Animals Studied Sixty‐eight privately owned dogs. Procedures The study categorized canine eyes into three groups based on the craniofacial ratio (CFR): brachycephaly (≤0.52), mesocephaly (>0.52 to <0.67), and ...
