Post Activation Potentiation Is Greater in Human Triceps Brachii Versus Triceps Surae Muscles

Muscle &Nerve, EarlyView.
ABSTRACT Introduction/Aims Voluntary muscle contractions result in a temporary increase in twitch force, a phenomenon termed post activation potentiation (PAP). In rodents and other species, PAP is observed predominantly or exclusively in fast twitch muscles. However, it has been suggested that in humans, PAP occurs more or less independently of muscle

Theoretical Modeling and Experimental Detection of the Extracellular Phasic Impedance Modulation in Rabbit Hearts

Frontiers in Physiology, 2019
Theoretical cardiac electrophysiology focuses on the dynamics of the membrane and sarcoplasmic reticulum ion currents; however, passive (e.g., membrane capacitance) and quasi-active (response to small signals) properties of the cardiac sarcolemma, which ...

Dorsomorphin, a Selective Small Molecule Inhibitor of BMP Signaling, Promotes Cardiomyogenesis in Embryonic Stem Cells [PDF]

, 2011
Background: Pluripotent embryonic stem (ES) cells, which have the capacity to give rise to all tissue types in the body, show great promise as a versatile source of cells for regenerative therapy. However, the basic mechanisms of lineage specification of

Lithospermic Acid Improves Doxorubicin‐Induced Cardiomyopathy Through Sirtuin‐3‐Mediated Deacetylation of p53

Phytotherapy Research, EarlyView.
Lithospermic acid (LA) inactivates the p53 signaling pathway via directly targeting SIRT3, thereby alleviating oxidative stress and abnormal apoptosis in the progression of doxorubicin (Dox)‐induced cardiomyocytes. ABSTRACT Doxorubicin (Dox)‐induced cardiomyopathy (DIC) is characterized by significant myocardial damage that can progress to dilated ...

Heart‐On‐a‐Chip with Integrated Ultrasoft Mechanosensors for Continuous Measurement of Cell‐ and Tissue‐Scale Contractile Stresses

Small, EarlyView.
We present a heart‐on‐a‐chip platform embedded with ultrasoft mechanosensors for real‐time, multi‐scale stress mapping in engineered cardiac tissues. The system enables simultaneous quantification of local cell‐generated stresses and global tissue contractile forces.

Effects of eugenol on resting tension of rat atria

Brazilian Journal of Medical and Biological Research, 2014
In cardiac and skeletal muscle, eugenol (μM range) blocks excitation-contraction coupling. In skeletal muscle, however, larger doses of eugenol (mM range) induce calcium release from the sarcoplasmic reticulum.

Vasoreactivity as a Measure of Kidney Viability During Ex Vivo Normothermic Machine Perfusion

Artificial Organs, EarlyView.
This study aimed to investigate the influence of warm ischemic injury on renal vascular responsiveness to vasoactive drugs during normothermic machine perfusion (NMP). We found that the vascular responses to dopamine and norepinephrine could be used as objective indicators to assess kidney viability during NMP.
