Super‐Resolution Ultrasound Based Cell Tracking With Polymeric Nanobubbles

Advanced Materials, EarlyView.
This study presents a super‐resolution ultrasound platform for tracking cells in vivo. Biocompatible polymeric nanobubbles are used as highly echogenic intracellular labels. Following the injection of cells and microbubbles, ultrasound localization microscopy (ULM) can dynamically match the microvascular architecture and individual cell trajectories ...

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 ...

Method for noninvasive measurement of central aortic systolic pressure

Clinical Cardiology, 1987
AbstractA method for noninvasive generation of central aortic systolic pressure curves is presented. The method is based on plotting the occlusive pressure values applied at the brachial artery level against the time intervals needed for the aortic pressure wave to equalize and break through the occlusive pressure at the brachial artery level.

Large‐Scale and Cost‐Effective Fabrication of Ultra‐Thin, Biodegradable Microelectrode Arrays and Pressure Sensors Using Laser Micromachining

Advanced Materials Technologies, EarlyView.
A mask‐free and cost‐effective UV‐pico‐second laser‐based microfabrication method is proposed to fabricate large‐area biodegradable microelectrode arrays and pressure sensors. These devices demonstrate low impedance, good conformability, excellent biocompatibility, and rapid degradation, providing a new route for next‐generation transient electronics ...

Arterial elastic properties and central aortic pressure in patients with ankylosing spondylitis

Научно-практическая ревматология, 2019
In recent years, arterial stiffness has been shown to be increased in ankylosing spondylitis (AS). However, this issue has not been sufficiently studied today.Objective: to investigate central aortic pressure values and pulse wave velocity (PWV) in ...

Additive Manufacturing of Patient‐Specific Intracranial Aneurysm Cell Culture Models

Advanced Materials Technologies, EarlyView.
Patient‐specific intracranial aneurysm models were fabricated using chocolate moulding, 3D printed water‐soluble cores, and direct resin 3D printing. Moulding PDMS around sacrificial cores made of chocolate or 3D printed water‐soluble resin yielded accurate, expandable, and endothelializable models that outperformed resin‐based approaches.

P5.31 CENTRAL PRESSURES ARE HIGHER IN PATIENTS WITH TRANSIENT ISCHAEMIC ATTACK (TIA) THAN HEALTHY ADULTS

Artery Research, 2013
Introduction: The increased risk of stroke following a Transient Ischaemic Attack (TIA) is well established. Central aortic pressure, a marker of arterial stiffness, is emerging as a predictor of cardiovascular events including stroke.

Augmentation index and central aortic blood pressure in patients with abdominal aortic aneurysms

Journal of Hypertension, 2010
Abdominal aortic aneurysm (AAA) is a life-threatening disease as rupture of the aneurysm is associated with high mortality. The likelihood that an AAA will rupture is particularly influenced by the diameter of the aneurysm and the rate of expansion; the reasons for fast expansion are largely unknown.

Central aortic pressure augmentation in stable renal transplant recipients [PDF]

Kidney International, 2002
Premature cardiovascular disease is the leading cause of death in renal transplant recipients and classical risk factors significantly underestimate the risk. The increased effect of arterial wave reflections on central arteries has recently been shown to be an important independent predictor of cardiovascular mortality in chronic hemodialysis patients.
