P65 GENDER DIFFERENCES OF AORTIC WAVE REFLECTION AND INFLUENCE OF MENOPAUSE ON CENTRAL BLOOD PRESSURE IN PATIENTS WITH ARTERIAL HYPERTENSION

Artery Research, 2017
Background: Evidences suggest that central hemodynamics indexes are independent predictors of future cardiovascular events and all-cause mortality. Multiple factors have been pointed to have potential influence on central aortic function: height, heart ...

P86 Can Central Blood Pressure be Accurately Estimated in Individuals with and Without Systolic Blood Pressure Amplification?

Artery Research, 2020
Introduction: Systolic blood pressure (SBP) does not always amplify from central to peripheral arteries. Individuals without SBP amplification (SBPamp) have higher aortic blood pressure (BP) despite similar brachial cuff SBP.

Topically Delivered Treg‐Attracting Microparticle‐Hydrogel Composites Recruit Regulatory T Cells and Limit Cardiac Injury After Severe Ischemia

Advanced Healthcare Materials, EarlyView.
CCL22‐releasing PLGA microparticles (MP) suspended in topically applied hydrogels (HEART) establish a sustained chemokine gradient at the injured myocardium. HEART recruits CCR4+ regulatory T cells, reduces infarct size and graft fibrosis, and improves cardiac function.

VASCULAR WALL RIGIDITY IN PATIENTS WITH DEGENERATIVE AORTIC STENOSIS BEFORE AND AFTER AORTIC VALVE SURGICAL PROSTHESIS

Байкальский медицинский журнал, 2023
Introduction. The most common cause of aortic valve surgery is aortic stenosis. So far, the focus has been on evaluating the valve itself, while increasing aortic stiffness increases the load on the left ventricle, contributing to greater impairment of ...

Atom‐Efficient Cerium‐Based Molecular Cages as Biocompatible Reactive Oxygen Scavengers

Advanced Healthcare Materials, EarlyView.
Discrete mixed‐valent cerium molecular cages organize accessible redox centers within confined coordination environments and scavenge superoxide, hydrogen peroxide, and hydroxyl radicals. Encapsulation of the lead cage in an ROS‐responsive DTP nanoplatform enables lesion‐associated delivery, attenuates macrophage oxidative stress and inflammation, and ...

3.6 LONGITUDINAL CHANGES IN AORTIC RESERVOIR FUNCTION INDEPENDENTLY PREDICT DECLINING RENAL FUNCTION AMONG HEALTHY INDIVIDUALS

Artery Research, 2016
Objectives: Aortic reservoir function independently predicts end organ damage in cross sectional analyses. However, longitudinal associations are more important regarding causation, but this has never been examined and was the goal of this study ...

Pressure‐Assisted Drug Delivery Using High‐Pressure Balloon Platform Improves Vascular Drug Penetration and Anti‐Restenotic Effects

Advanced Healthcare Materials, EarlyView.
A dual‐layer high‐pressure drug‐coated balloon (HP@DCB) increased balloon‐wall contact and promoted deeper paclitaxel (PTX) penetration than a conventional noncompliant DCB. In in vivo study, HP@DCB treatment improved luminal patency and reduced neointimal hyperplasia, supporting pressure‐assisted drug delivery as a promising strategy for enhancing the
