Microfabricated Anisotropic Myobundles for the Scalable Production of Cardiac Tissue Grafts
Advanced Functional Materials, EarlyView.Controlling the anisotropy of cardiac tissue remains an outstanding challenge in the field of cardiac tissue engineering. Here, we introduce an approach to generate anisotropic cardiac myobundles using cell‐adhesive, synthetic, electrospun fibers and stem cell‐derived cardiac fibroblasts.

Enhancing Maturation of Human Neuromuscular Organoids via Electrical Stimulation
Advanced Science, EarlyView.A framework for on‐demand and non‐invasive exposure of human neuromuscular organoids (NMOs) to electrical stimuli is established to promote their maturation. The robustness and effectiveness of different stimulation regimes are evaluated via thorough characterization of organoid tissue structure and contraction capacity. Chronic electrical stimulation,

Gaining new understanding of sarcomere length non-uniformities in skeletal muscles
Frontiers in PhysiologySarcomere lengths are non-uniform on all structural levels of mammalian skeletal muscle. These non-uniformities have been associated with a variety of mechanical properties, including residual force enhancement and depression, creep, increased force ...

EFFECT OF PROTEIN OXIDATION ON PARTICLE SIZE OF MYOFIBRILS [PDF]
, 2016 In order to study the effect of protein oxidation on the structure of myofibrils, extracted myofibrils from porcine longissimus dorsi muscle were incubated with different concentrations of the oxidant NaClO (0, 5, 10, 20 and 40 mM) at 5 ºC for 16 h ...

Degradation of α-actinin during Ca2+-sensitive proteolysis of myofibrils
, 1985 The noted loss of α-actinin from the Z-line of myofibrils during post-mortem autolysis, probably following the action of calcium-activated protease, has previously been attributed to its release without degradation.

Measurement of Calcium Dissociation Rates from Troponin C in Rigor Skeletal Myofibrils
Frontiers in Physiology, 2011 Ca2+ dissociation from the regulatory domain of troponin C may influence the rate of striated muscle relaxation. However, Ca2+ dissociation from troponin C has not been measured within the geometric and stoichiometric constraints of the muscle fiber ...

Cardiac morphological and morphometric analysis of Ardea alba
The Anatomical Record, EarlyView.Abstract Ardea alba (Linnaeus, 1758) is a widely distributed heron species whose cardiovascular morphology remains poorly described. This study aimed to characterize the cardiac morphology and morphometry of adult A. alba. Ten specimens were analyzed using radiographic, morphometric, histological, scanning electron microscopy, and three‐dimensional ...
