Extracellular Vesicle cystatin c is associated with unstable angina in troponin negative patients with acute chest pain.

open access: yesPLoS ONE, 2020
BackgroundDespite the use of high-sensitive cardiac troponin there remains a group of high-sensitive cardiac troponin negative patients with unstable angina with a non-neglectable risk for future adverse cardiovascular events, emphasising the need for ...

Incidence and prognosis associated with troponin elevation after cardiac surgery: a prospective cohort study

open access: yesBMJ Open, 2022
Objective Cardiac troponin is used as a prognostic biomarker after cardiac surgery. However, numerous confounding elements, such as inflammation, liver and renal function biomarkers, have been associated with troponin variations.

Ca2(+)-dependent interactions between the C-helix of troponin-C and troponin-I. Photocross-linking and fluorescence studies using a recombinant troponin-C. [PDF]

open access: yesJournal of Biological Chemistry, 1990
We have used in vitro mutagenesis to synthesize in Escherichia coli a recombinant rabbit skeletal troponin-C (designated as TnC57) in which Cys-98 was replaced with leucine, and Ala-57 in the C-helix of the N-terminal domain was replaced with cysteine.

A Dilated Cardiomyopathy Troponin C Mutation Lowers Contractile Force by Reducing Strong Myosin-Actin Binding*

open access: yesJournal of Biological Chemistry, 2010
In this study we explore the mechanisms by which a double mutation (E59D/D75Y) in cardiac troponin C (CTnC) associated with dilated cardiomyopathy reduces the Ca2+-activated maximal tension of cardiac muscle. Studying the single mutants (i.e.

Volumetric 3D Printing and Melt‐Electrowriting to Fabricate Implantable Reinforced Cardiac Tissue Patches

open access: yesAdvanced Materials, EarlyView.
This study presents an implantable reinforced cardiac patch (RCPatch) combining volumetrically 3D‐printed metamaterials with melt‐electrowritten (MEW) meshes. The design integrates tunable stiff polymer structures with soft, cell‐laden hydrogels. The RCPatch withstands suturing, intraventricular pressure, and cardiac contraction in a large animal ...

Sacrificial Biofabrication for Vascularization: Concept, Materials, Technologies, and Applications

open access: yesAdvanced Materials, EarlyView.
Vasculature is indispensable for tissue viability in regenerative medicine. The sacrificial biofabrication enables precise fabrication of vascular channels by using temporary templates that are subsequently removed. This review defines the concept and delves into sacrificial materials, surrounding materials, fabrication technologies, and biomedical ...

Molecular dynamics simulations of the cardiac troponin complex performed with FRET distances as restraints. [PDF]

open access: yesPLoS ONE, 2014
Cardiac troponin (cTn) is the Ca(2+)-sensitive molecular switch that controls cardiac muscle activation and relaxation. However, the molecular detail of the switching mechanism and how the Ca(2+) signal received at cardiac troponin C (cTnC) is ...

Cats with thermal burn injuries from California wildfires show echocardiographic evidence of myocardial thickening and intracardiac thrombi. [PDF]

open access: yes, 2020
Recent increases in the prevalence and severity of wildfires in some regions have resulted in an increased frequency of veterinary burn patients. Few studies exist regarding diagnostics and management of burn wounds in veterinary patients and current ...

Utility of B-type natriuretic peptide in predicting medium-term mortality in patients undergoing major non-cardiac surgery [PDF]

open access: yes, 2007
We assessed the ability of pre-operative B-type natriuretic peptide (BNP) levels to predict medium-term mortality in patients undergoing major noncardiac surgery.

The Bionic Interface: Considering the Material Mediated Electrical Stimulation of Stem Cells

open access: yesAdvanced Materials, EarlyView.
Electrical stimulation directs stem cell fate in tissue engineering. Cellular responses are influenced by membrane properties, intrinsic cell state, material charge‐transport characteristics, and the applied electrical signal. Additionally, a material’s ability to inject, store, and redistribute charge further modulates these responses.
