Advanced Robotics Research, EarlyView.A flexible, skin‐integrated electromagnetic actuator is developed for wearable virtual/augmented reality (VR/AR) haptic systems. A tunable design model enables control over displacement and resonance frequency. The system is validated through a custom VR application with a 6 × 4 actuator array, demonstrating real‐time, spatially targeted tactile ...

Colour Doppler imaging in Takayasu's arteritis [PDF]
British Journal of Ophthalmology, 1998 Editor,—Takayasu’s arteritis (TA) is a systemic necrotising vasculitis of unknown aetiology whose characteristic ocular manifestations relate to ocular ischaemia. Orbital colour Doppler imaging (CDI) is useful to evaluate haemodynamics of the orbital circulation and its abnormalities.1 We report the ophthalmic artery blood flow in two patients with TA ...

A Soft Robotic Model for Simulating Heart Valve Disease and Cardiac Interventions
Advanced Science, EarlyView.This paper introduces a fully synthetic fabrication methodology for a soft robotic, in‐vitro model of the left‐heart, complete with a functioning mitral valve apparatus. With a view towards patient‐specific modeling, we demonstrate physiological flow and pressure waveforms, tunable mitral valve function with clinical imaging compatibility, and its use ...

G3BP1 Succinylation at K413 is Critical for Cardiac Function by Modulating PI3K‐AKT‐mTOR Signal Axis
Advanced Science, EarlyView.Schematic illustrating the impact of G3BP1 succinylation at K413 on cardiac function. In the healthy human heart, G3BP1 succinylation maintains homeostatic mTOR signaling. In patients with dilated cardiomyopathy (DCM) and heart failure (HF), G3BP1 de‐succinylation induces RagA expression and disrupts the binding of the TSC1/2 complex, leading to the ...

Three-dimensional echocardiography of colour Doppler flow
Archives of Cardiovascular Diseases, 2010 Three-dimensional echocardiography of colour Doppler flow developed quickly with the advent of three-dimensional echocardiography. An increasing amount of research has shown that three-dimensional echocardiography of colour Doppler flow is feasible and facilitates measurement of stroke volume and cardiac output, and assessment of heart valve and ...

Advanced Science, EarlyView.Endothelial GPR68 is identified as a critical regulator of collateral artery growth in peripheral artery disease. Genetic and pharmacological evidence demonstrates that GPR68 integrates hemodynamic cues to drive monocyte recruitment and inflammatory remodeling, thereby promoting collateral arteriogenesis and tissue perfusion after ischemia ...

Characterisation of the Colour Doppler “Twinkle” Artefact
Physica Medica, 2012 This investigation involved the development of a range of Colour Doppler Twinkle Artefact phantoms to characterise and quantify the “Twinkle” artefact which is often present when an irregular structure is encountered in the imaged field of view. The artefact occurs in both colour and power Doppler ultrasound imaging and manifests as a false depiction ...

Advanced Science, EarlyView.This study reveals that Alzheimer's disease–linked APP expression in bone‐forming cells drives skull bone marrow remodeling and alters its vascular connections to the brain. These changes disrupt immune cell trafficking, cerebral blood flow, and cognition. Targeting bone marrow macrophages restores brain function, highlighting a previously unrecognized
