Association of aortic and main left coronary aneurysms with severe aortic insufficiency in Takayasu’s arteritis

Clinics and Practice, 2011
Takayasu’s arteritis is a granulomatous vasculitis of unknown etiology that affects mainly the aorta and its branches. As a result of intimal fibroproliferation, segmental stenosis, occlusion, dilatation, and aneurysmal formation of the involved vessels ...

Flow Analysis in Pathological Microvascular Models by Ultrasound Localization Microscopy

Advanced Materials Technologies, EarlyView.
This study presents a new platform combining ultrasound localization microscopy with biomimetic gelatin phantoms to analyze flow dynamics in small vessels with narrowing or obstructions. Using microbubble tracking, the method enables high‐resolution velocity mapping in 100–500 µm channels, revealing flow changes in pathological microvascular conditions

One‐Step Covalent Biofunctionalization of Tubular Constructs Enabled by Surface‐Embedded Radicals

Advanced Materials Technologies, EarlyView.
Uniform covalent biofunctionalization of tubular constructs is achieved in one step using surface‐embedded radicals generated by a novel plasma immersion ion implantation (PIII) technology. This scalable, solvent‐free technology advances bioengineered tubes for tissue engineering and implant applications.

Immunohistochemical diagnosis of primary cardiac leiomyosarcoma in a Latin American patient

Rare Tumors, 2017
Primary cardiac malignancies are rare entities. Although sarcomas enclosed the main group of malignant heart neoplasms, primary cardiac leiomyosarcomas are extremely rare and constitutes less than 8% of cardiac tumors.
