Non-contact transmittance photoplethysmographic imaging (PPGI) for long-distance cardiovascular monitoring [PDF]

open access: yesarXiv, 2015
Photoplethysmography (PPG) devices are widely used for monitoring cardiovascular function. However, these devices require skin contact, which restrict their use to at-rest short-term monitoring using single-point measurements. Photoplethysmographic imaging (PPGI) has been recently proposed as a non-contact monitoring alternative by measuring blood ...

Physician-modified aortic cuff to “stabilize” paravisceral aortic thrombus and minimize risk of distal embolization during pararenal aneurysm repair with fenestrated stent graft

open access: yesJournal of Vascular Surgery Cases and Innovative Techniques, 2022
As technology and surgeon experience evolve, endovascular repair of complex abdominal aortic aneurysms is often preferred in appropriately selected patients. However, the presence of pedunculated aortic thrombus represents a relative contraindication for

Ischemic Myocardium Targeting Peptide‐Guided Nanobubbles for Multimodal Imaging and Treatment of Coronary Microvascular Dysfunction

open access: yesAdvanced Healthcare Materials, EarlyView.
Nanobubbles functionalized with indocyanine green and ischemic myocardium‐targeting peptide effectively target cardiomyocytes and enable the multimodal (fluorescence, ultrasonic, and photoacoustic) imaging of ischemic myocardium in mice with coronary microvascular dysfunction (CMD).

Timely Management of Obstructive Prosthetic Valve Thrombosis

open access: yesJACC: Case Reports, 2019
Obstructive bioprosthetic valve thrombosis is associated with hemodynamic compromise, and evidence on management with fibrinolysis is limited. Echocardiography is required to assess thrombus size and its effects on valve gradients, area, and leaflet ...

Lycium‐Barbarum Polysaccharide‐Loaded Dual‐Crosslinked Rigid Hydrogel Enhances Bone Healing in Diabetic Bone Defects by Scavenging Reactive Oxygen Species

open access: yesAdvanced Healthcare Materials, EarlyView.
A novel hydrogel (HLBP) incorporating natural polysaccharides from goji berries is developed to enhance diabetic bone defect healing. The hydrogel efficiently scavenges ROS, improves osteogenic differentiation, and promotes in vivo bone regeneration. This strategy offers a biocompatible and localized approach, overcoming the challenges of traditional ...
