Advanced Functional Materials, EarlyView.Bio‐based and (semi‐)synthetic zwitterion‐modified novel materials and fully synthetic next‐generation alternatives show the importance of material design for different biomedical applications. The zwitterionic character affects the physiochemical behavior of the material and deepens the understanding of chemical interaction mechanisms within the ...

A heart in a heart: a case report of spontaneous flail of bicuspid aortic valve
Journal of Medical Case Reports, 2021 Background Aortic regurgitation is attributed to congenital and acquired abnormalities of the aortic valve or aortic valve supporting structures. The most common cause of aortic regurgitation is atherosclerotic degeneration of the valve, especially in ...

Cell Calcification Models and Their Implications for Medicine and Biomaterial Research
Advanced Healthcare Materials, EarlyView.Calcification, is the process by which the tissues containing minerals are formed, occurring during normal physiological processes, or in pathological conditions. Here, it is aimed to give a comprehensive overview of the range of cell models available, and the approaches taken by these models, highlighting when and how methodological divergences arise,

Bicuspid aortic valve associated with aortic thrombotic occlusion
The Egyptian Journal of Internal Medicine, 2016 The bicuspid aortic valve is associated with disorders of the aortic wall, including coarctation of the aorta and aortic dissection. The histologic abnormality underlying aortic complications in bicuspid aortic valve is cystic medial necrosis.

Osteoprotegerin inhibits aortic valve calcification and preserves valve function in hypercholesterolemic mice. [PDF]
PLoS ONE, 2013 There are no rigorously confirmed effective medical therapies for calcific aortic stenosis. Hypercholesterolemic Ldlr (-/-) Apob (100/100) mice develop calcific aortic stenosis and valvular cardiomyopathy in old age.

Advanced Healthcare Materials, EarlyView.Small‐diameter vascular grafts with compliance tunable by design are fabricated via melt electrowriting. By controlling the winding angle of intertwined helical fibers, grafts with compliances matching those of human vessels, from veins to arteries, are realized. This holds the potential of avoiding a compliance mismatch, which has been identified as a
