Understanding extracellular vesicles in antiaging

open access: yesPeriodontology 2000, EarlyView.
Abstract Background Aging is a multifactorial process marked by gradual cellular dysregulation, regulated by hallmarks, including genomic instability, mitochondrial dysregulation, and chronic inflammation. Extracellular vesicles (EVs), especially exosomes, have emerged as pivotal mediators of cell‐to‐cell communication with potential roles in both ...

Multistatic micro-Doppler radar signatures of personnel targets

open access: yes, 2016
This study extends the theory of the micro-Doppler effect into the multistatic domain, and considers how the multistatic micro-Doppler signature (μ-DS) will affect radar automatic target recognition (ATR).

Quantifying microvascular responses to local heating using optical coherence tomography: Comparison between skin sites and sex differences

open access: yesExperimental Physiology, EarlyView.
Summary of the study design, metholodgy, results and conclusions. Abstract Due to a lack of technical capacity to directly visualise and quantify microvessels in the skin, little is known regarding regional and/or sex differences. We compared diameter, velocity, flow and density at four regional sites using a novel optical coherence tomography (OCT ...

Pseudo-Zernike moments based radar micro-Doppler classification

open access: yes, 2014
Reliable micro-Doppler signature classification requires the use of robust features describing uniquely the micromotion. Moreover, future applications of micro-Doppler classification will require meaningful representation of the observed target by using ...

Scaling temporal resolution from mice to humans: Challenges and innovations in preclinical imaging of translational models

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend Temporal scaling physiology differs significantly between mice and humans. Mice have higher metabolism, heart and respiratory rate, as well as faster blood flow rates, brain activity and physiological dynamics over time. These differences influence the temporal resolution needed in preclinical imaging of mouse models to ...

Multiscale four‐dimensional imaging of cardiac remodelling after myocardial infarction

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend Multiscale 4D imaging framework for integrated phenotyping of post‐infarction remodelling. Myocardial infarction triggers dynamic changes across mechanical, haemodynamic and biological axes, progressing from acute injury and inflammation to extracellular matrix remodelling and scar maturation.

SRCNN: Stacked-Residual Convolutional Neural Network for Improving Human Activity Classification Based on Micro-Doppler Signatures of FMCW Radar [PDF]

open access: yesJournal of Electromagnetic Engineering and Science
Current methods for daily human activity classification primarily rely on optical images from cameras or wearable sensors. Despite their high detection reliability, camera-based approaches suffer from several drawbacks, such as low-light conditions ...

Tendinopathy: Types, Epidemiology, Molecular Mechanisms, and Future Precision‐Oriented Therapeutic Strategies

open access: yesMedComm, Volume 7, Issue 11, November 2026.
This review presents tendinopathy as a heterogeneous disorder driven by dynamic interactions among mechanical sensing, inflammation, angiogenesis and innervation, and extracellular matrix remodeling. Integrating clinical phenotypes with imaging, biomarkers, and multi‐omics may enable molecular subtyping and mechanism‐guided interventions, advancing ...
