Volumetric 3D Printing and Melt‐Electrowriting to Fabricate Implantable Reinforced Cardiac Tissue Patches

Advanced Materials, EarlyView.
This study presents an implantable reinforced cardiac patch (RCPatch) combining volumetrically 3D‐printed metamaterials with melt‐electrowritten (MEW) meshes. The design integrates tunable stiff polymer structures with soft, cell‐laden hydrogels. The RCPatch withstands suturing, intraventricular pressure, and cardiac contraction in a large animal ...

Modeling to close of interatrium septum defects of the heart

Pediatrician (St. Petersburg), 2015
Atrial septal defect (ASD) of the secundum type are the most common lesions. More than half of the century a surgeons are operating second defect of ASD of the heart. But a choice to close this defect have the empirical character. In this work the method of the modeling on computer was used.

Carbon Quantum Dots Assisted Virus Tracking: From Skin to Brain

Advanced Materials, EarlyView.
A novel carbon quantum dots‐dissolvable microneedle, CQDs‐dMN system, enables painless delivery and real‐time tracking of HSV‐1. The HSV‐1 is labeled with fluorescent CQDs and delivered to the skin dermis, minimizing damage compared to traditional methods.

Echocardiographic analysis of dogs before and after surgical treatment of brachycephalic obstructive airway syndrome

Frontiers in Veterinary Science, 2023
Brachycephalic dogs with brachycephalic obstructive airway syndrome (BOAS) are a valuable animal model for obstructive sleep apnea (OSA) in humans. Clinical signs of upper airway obstruction improve after surgical treatment of BOAS, but the impact of ...

Copper Stress Response of Antibiotic‐Resistant and Copper‐Tolerant Enterococcus faecium and the Antibacterial Efficacy of Functionalized Copper Surfaces

Advanced Materials Interfaces, EarlyView.
This study examines how different laser‐patterned copper and brass surfaces, including copper coatings, affect the survival of vancomycin‐resistant Enterococcus faecium. Using microscopy and genome analysis, the results show that copper tolerance varies between strains and can increase after vancomycin exposure.

Chronic Psychological Stress Induces Cardiomyocyte Hypertrophy Through Corticosterone‐Glucocorticoid Receptor‐LAMA5 Axis

Advanced Science, EarlyView.
In vivo experiments suggest that cardiomyocyte hypertrophy is an early manifestation of cardiac pathological changes induced by chronic psychological stress. In vivo and in vitro experiments suggest that the corticosterone‐glucocorticoid receptor‐LAMA5 axis mediates cardiomyocyte hypertrophy induced by chronic psychological stress. The clinical results
