A Soft Robotic Model for Simulating Heart Valve Disease and Cardiac Interventions

open access: yesAdvanced Science, EarlyView.
This paper introduces a fully synthetic fabrication methodology for a soft robotic, in‐vitro model of the left‐heart, complete with a functioning mitral valve apparatus. With a view towards patient‐specific modeling, we demonstrate physiological flow and pressure waveforms, tunable mitral valve function with clinical imaging compatibility, and its use ...

A possible new approach in the prediction of late gestational hypertension: The role of the fetal aortic intima-media thickness [PDF]

open access: yes, 2017
The aim was to determine the predictive role of combined screening for late-onset gestational hypertension by fetal ultrasound measurements, third trimester uterine arteries (UtAs) Doppler imaging, and maternal history.

TrxR2 Lactylation Facilitates Mitochondrial Protection and Endothelial Ferroptosis Resistance in Diabetic Cardiomyopathy

open access: yesAdvanced Science, EarlyView.
TrxR2 deletion in diabetic mice suppresses TUFM‐AMPK‐FUNDC1‐dependent mitophagy in endothelial cells, resulting in SCP2 upregulation and mitochondrial translocation of ACSL4. Mitochondrial ACSL4 promotes mitochondrial eicosanoid biosynthesis and ferroptosis, thereby aggravating cardiac microvascular injury and diabetic cardiomyopathy.

Deep Learning Methods for Assessing Time‐Variant Nonlinear Signatures in Clutter Echoes

open access: yesAdvanced Intelligent Systems, EarlyView.
Motion classification from biosonar echoes in clutter presents a fundamental challenge: extracting structured information from stochastic interference. Deep learning successfully discriminates object speed and direction from bat‐inspired signals, achieving 97% accuracy with frequency‐modulated calls but only 48% with constant‐frequency tones.

Color Doppler ultrasound characteristics after subinguinal microscopic varicocelectomy

open access: yesMedical Ultrasonography, 2017
Aim: The present study evaluated the effect of differences in the peak systolic velocity (PSV) and resistive index (RI) in the testicular artery (TA), capsular artery (CA), and intratesticular artery (ITA) after microscopic subinguinal varicocelectomy (MSV) on postoperative pain and semen parameters.

Age and gender effects on echocardiographic and histopathological cardiac phenotypes in healthy adult mice

open access: yesAnimal Models and Experimental Medicine, EarlyView.
This study investigated the impact of age and sex on cardiac phenotypes in healthy adult C57BL/6J mice using echocardiography and histopathological analyses. Findings revealed that female mice demonstrated more pronounced global cardiac chamber dilation during aging.

The characteristics of collagen‐induced rheumatoid arthritis in macaques and the changes of heart

open access: yesAnimal Models and Experimental Medicine, EarlyView.
The disease progression in CIA macaques was categorized into three stages: IIR (days 14–34): The indicators related to rheumatoid arthritis and the levels of immunoglobulin were all elevated. There was a small amount of joint effusion, edema and mild synovial hyperplasia. No joint swelling was observed by naked eye.
