Nanomaterials for Cardiac Myocyte Tissue Engineering [PDF]

open access: yesNanomaterials, 2016
Since their synthesizing introduction to the research community, nanomaterials have infiltrated almost every corner of science and engineering. Over the last decade, one such field has begun to look at using nanomaterials for beneficial applications in tissue engineering, specifically, cardiac tissue engineering. During a myocardial infarction, part of

Bioprinted Excitable Tissues with Multistimulation Systems for Promoting Function and Maturation

open access: yesAdvanced NanoBiomed Research, EarlyView.
This review provides an overview of stimulation strategies used to enhance the functional maturation of bioprinted excitable tissues. It addresses key limitations in physiological performance of bioprinted excitable tissues, outlines major stimulation modalities—including electrical, mechanical, optical, magnetic, ultrasound, and hybrid—and examines ...

Confocal laser scanning microscope, raman microscopy and western blotting to evaluate inflammatory response after myocardial infarction [PDF]

open access: yes, 2015
Cardiac muscle necrosis is associated with inflammatory cascade that clears the infarct from dead cells and matrix debris, and then replaces the damaged tissue with scar, through three overlapping phases: the inflammatory phase, the proliferative phase

Integrating ER and Mitochondrial Proteostasis in the Healthy and Diseased Heart

open access: yesFrontiers in Cardiovascular Medicine, 2020
The integrity of the proteome in cardiac myocytes is critical for robust heart function. Proteome integrity in all cells is managed by protein homeostasis or proteostasis, which encompasses processes that maintain the balance of protein synthesis ...

Electron-conformational transformations in nanoscopic RyR channels govern both the heart's contraction and beating [PDF]

open access: yes, 2011
We show that a simple biophysically based electron-conformational model of RyR channel is able to explain and describe on equal footing the oscillatory regime of the heart's cell release unit both in sinoatrial node (pacemaker) cells under normal ...

The role of inhibitory G proteins and regulators of G protein signaling in the in vivo control of heart rate and predisposition to cardiac arrhythmias [PDF]

open access: yes, 2012
Inhibitory heterotrimeric G proteins and the control of heart rate. The activation of cell signaling pathways involving inhibitory heterotrimeric G proteins acts to slow the heart rate via modulation of ion channels.

Imaging Calcium Sparks in Cardiac Myocytes [PDF]

open access: yes, 2010
Calcium ions play fundamental roles in many cellular processes in virtually all type of cells. The use of Ca(2+) sensitive fluorescent indicators has proven to be an indispensable tool for studying the spatio-temporal dynamics of intracellular calcium ([Ca(2+)](i)).

Optimizing biophysical properties of cellular niches to enhance stem cell‐derived extracellular vesicle function in musculoskeletal regeneration

open access: yesBMEMat, EarlyView.
Extracellular vesicles (EVs) derived from stem cells show promise for applications in regenerative medicine, but their scalability and yield remain challenges. This review explores the approaches for biophysical modulations within cell niches on EV properties, discusses the current clinical application of EVs, and provides an outlook on the existing ...

Sex‐specific activation of SK current by isoproterenol facilitates action potential triangulation and arrhythmogenesis in rabbit ventricles [PDF]

open access: yes, 2018
Sex has a large influence on cardiac electrophysiological properties. Whether sex differences exist in apamin‐sensitive small conductance Ca2+‐activated K+ (SK) current (IKAS) remains unknown.
