Multiple-Step Injection Molding for Fibrin-Based Tissue-Engineered Heart Valves

open access: yesTissue Engineering. Part C, Methods, 2015
Heart valves are elaborate and highly heterogeneous structures of the circulatory system. Despite the well accepted relationship between the structural and mechanical anisotropy and the optimal function of the valves, most approaches to create tissue ...

Bioinspired Bromination Enables Extensible, Strain‐Stiffening Resilin Peptide Scaffolds with Tunable Degradation

open access: yesAdvanced Functional Materials, EarlyView.
Bioinspired bromination of a resilin‐derived peptide enables the fabrication of electrospun nanofibrous scaffolds that uniquely combine strain‐stiffening elasticity, proteolytic stability, and antioxidant functionality. These brominated peptide–gelatin hybrids mimic the extensibility of natural elastomers, demonstrating tunable mechanical resilience ...

Relationship between Calcium, Phosphorous and Parathoromone with Calcification of Heart Valves In Dialyzed Patients In Qom, 1385-1386 [PDF]

open access: yesMajallah-i Dānishgāh-i ̒Ulūm-i Pizishkī-i Qum, 2008
Background and ObjectivesMetastatic calcification is usually found in patients with chronic renal failure and hemodialyzed patients. Heart calcification becomes worse in hemodialyzed patients due to several factors.

Tissue Heart Valve Replacement at BSMMU- Initial Experience with Two Cases

open access: yesBangabandhu Sheikh Mujib Medical University Journal, 2010
Research on prosthesis to replace diseased heart valves began almost simultaneously with mechanical valves which are durable but with inherent thromboembolic complication requiring life-long anticoagulant therapy and tissue valves which are more prone to

Chiral Nanohoops as an Efficient Spin Polarization System

open access: yesAdvanced Functional Materials, EarlyView.
Chiral conjugated nanohoops with a central dibenzopentalene unit exhibit 90% spin polarization at low voltage and high conductivity. These properties make them ideal components in molecular spintronics applications. Abstract A central challenge in molecular spintronics is to achieve a high spin polarization at low operating voltages and ambient ...

Recurrent infective endocarditis causing heart valve failure: A case report

open access: yesHuman Pathology: Case Reports, 2017
Infective endocarditis (IE) is an infection that does not usually respond rapidly to treatment, often because its early symptoms are non-specific. The diseased valves (native or bioprosthetic) may be calcified and the thrombotic vegetations on them ...
