Ultrasound phonocardiography for detecting thrombotic formations on bileaflet mechanical heart valves

open access: yes, 2013
The main disadvantage of mechanical heart valves is due to thrombosis, which is a serious complication associated with high morbidity and mortality. The early detection of thrombotic formations is crucial for a prompt diagnosis and proper therapy before ...

Evaluation of cardiac histology and cell death markers during the progression of diabetes in a streptozotocin‐induced diabetes rat model

open access: yesAnimal Models and Experimental Medicine, EarlyView.
Daily insulin administration in streptozotocin‐induced diabetic rats prevented cardiac damage associated with diabetic cardiomyopathy, including hypertrophy, fibrosis, and expression of cell death markers, at 12 weeks. However, cyclophilin D, a marker of mitochondrial permeability transition pore‐opening‐associated cell death (necrosis), was observed ...

Chrysin alleviates pressure overload–induced myocardial remodeling through regulating the PI3K/AKT/NRF2 pathway–mediated oxidative stress response

open access: yesAnimal Models and Experimental Medicine, EarlyView.
In this study, we primarily simulated pathological myocardial remodeling induced by transverse aortic constriction surgery and found significant cardiac hypertrophy and fibrosis, characterized by deteriorated cardiac function. Oxidative stress response is considered as a pivotal pathological process, which contributes to inflammation and apoptosis of ...

Research on Diaphragm Pump Fault Diagnosis Method Based on Res‐DCB‐Net

open access: yesAsia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT Nonstationary pressure pulsation signals of diaphragm pumps contain strong background noise and coupled characteristics. This makes it challenging to extract incipient fault features and to decouple faults with similar physical mechanisms. To address these limitations, this paper proposes a spatiotemporal fault diagnosis model named Res‐DCB ...

Hydrogen Permeability of Tubular Polymer Membranes for Biological Methanation Membrane Reactors

open access: yesJournal of Applied Polymer Science, EarlyView.
A reproducible method for permeability measurements of tubular polymer membranes is developed and combined with a comprehensive review of hydrogen permeability data. Based on this analysis, a suitable tubular polymer membrane is identified for application in biological methanation within membrane reactors.

Morphological and morphometric aspects of the equine aortic valve: New insights for comparative studies in mammals

open access: yesThe Anatomical Record, EarlyView.
Abstract New data on the equine aortic valve obtained using advanced techniques is especially important given the greater availability of animal models for translational research. Here we characterized the morphological and morphometric aspects of the equine aortic valve from 60 healthy hearts collected at equine abattoirs.
