Effect of hot isostatic pressing on microstructure and properties of cooled hot dip aluminum coating in magnetic field.

The effect of hot isostatic pressing (HIP) on the microstructure and properties of hot dip aluminum coating cooled in a magnetic field was investigated in this study. In order to improve the microstructure and properties of magnetic dip aluminum coating, hot isostatic pressing technology was used for post-treatment. Initially, a traditional aluminum-impregnated coating was prepared on the surface of titanium alloy TA15, an alternating electromagnetic field was applied during the forming and solidification process of the coating.

Complete Endovascular Reconstruction of the Canine Ascending Aorta, Aortic Arch, and Supra-Aortic Vessels by Implanting a New Unibody Outer Double-Branched Stent-Graft.

Purpose: We evaluated the feasibility and safety of using a new unibody outer double-branched stent-graft system to reconstruct the canine ascending aorta, aortic arch, and supra-aortic vessels.

Materials And Methods: The outer-branched stent-graft was a unibody design. The branched stent-graft consisted of a main stent-graft and 2 branches.

A canine model of aortic arch aneurysm created with autologous pericardium.

Background: To establish a canine model of aortic arch aneurysm that is suitable for research on new devices and techniques applied to the aortic arch.

Materials And Methods: Fifteen mongrel dogs underwent surgery. The autologous pericardial patch was sewn on the aortotomy site in the anterior wall of the aortic arch.

Inhibition of XIST attenuates abdominal aortic aneurysm in mice by regulating apoptosis of vascular smooth muscle cells through miR-762/MAP2K4 axis.

Abdominal aortic aneurysm (AAA) is a common chronic aortic degenerative disease. Long non-coding RNA X-inactive specific transcript (XIST) is associated with the progression of AAA, while the underlying mechanism is still unclear. We investigated the functional role of XIST in AAA.

Mechanism of neuronal activity and synaptic transmission in rostral ventrolateral medulla.

Rostral ventrolateral medulla (RVLM) plays an essential role in blood pressure homeostasis. This study was aimed to investigate the mechanism of neuronal activity and synaptic transmission in the RVLM. Medulla oblongata slices were carefully obtained from brainstem of rats.

Comparison of Pathogenic Mechanisms Underlying Single and Recurrent Venous Thromboembolism Based on Gene Expression Profiling.

Background: Unprovoked venous thromboembolism (VTE), generally divided into single and recurrent categories, is a common leading cause of morbidity and mortality in a real-world population. This study was aimed to explore the similarities and differences in the mechanisms of single and recurrent VTE.

Methods: Gene expression data (GSE19151) generated from 63 healthy controls, 32 single, and 38 recurrent VTE patients were analyzed.
