Electropermanent Magnetic Muscles: Power‐Efficient, Low‐Voltage, Compact Magnetic Actuators to Power Wearables and Untethered Robots

Advanced Intelligent Systems, EarlyView.
This work presents compact, low‐voltage actuators based on electropermanent magnetic interactions. The actuators show good overall performance across key metrics and are implemented in wearable devices and untethered robots. Their ability to operate in different configurations and hold positions without energy input highlights their potential for ...

The use of transgenic animals for xenotransplantation: An update

Animal Models and Experimental Medicine, EarlyView.
One way to produce genetically modified pigs is to use somatic cell nuclear transfer (SCNT). This procedure involves removing the metaphase plate from a mature oocyte using micromanipulation and then transferring the modified nucleus from the donor somatic cell to the oocyte.

Bridging aortic valve surgery to 21st century. what can a surgeon do [PDF]

, 2019
Aortic valve stenosis is the most clinically relevant valvular heart disease in the elderlies. Surgical aortic valve replacement (SAVR) represented, for decades, the standard of care for the treatment of severe aortic stenosis.

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

The 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.

Replacement of pulmonary artery trunk in sheep using tubular valved heterograft in non-aldehydic preservation [PDF]

, 2012
INTRODUCTION: The cardiac bioprostheses are related to thromboembolic events, infectious and degenerative diseases. Wear is mainly attributed to the denaturation of collagen. Glutaraldehyde, the predominant method of preservation of bioprostheses, favors

A Streamline Strategy for Indication and Length of Telemetry Monitoring After TAVR

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Background Both indication and length of ECG telemetry monitoring (TM) after transcatheter aortic valve replacement (TAVR) are not well defined. Aims We hypothesize that a targeted strategy for monitoring conductive disorders (CD) post‐TAVR can reduce the need and duration of in‐hospital TM without compromising safety. Methods We prospectively
