Hypoxia Tolerance in Teleosts: Implications of Cardiac Nitrosative Signals
Frontiers in Physiology, 2018 Changes in environmental oxygen (O2) are naturally occurring phenomena which ectotherms have to face on. Many species exhibit a striking capacity to survive and remain active for long periods under hypoxia, even tolerating anoxia.

Kardiologia polska, 2012 We discuss the foundations of the theory of homeostasis within the framework of modern physics. We analyse the paradigm of homeostasis, which is based on the physical assumption that the internal environment undergoes random fluctuations around a steady state equilibrium. We show how the notion of homeodynamics extends the concept of homeostasis.

Adaptive 4D‐Printed Vascular Stents With Low‐Temperature‐Activated and Intelligent Deployment
Advanced Functional Materials, EarlyView.Microarchitected coronary artery stents were fabricated using a polycaprolactone (PCL)‐based shape memory polymer (SMP) composite via projection micro‐stereolithography (PµSL) 4D printing. By incorporating diethyl phthalate (DEP) as a plasticizer, the thermal transition temperature (Ttran) was modulated to about 37°C, enabling rapid and autonomous ...

Effects of Tetrodotoxin on the Mammalian Cardiovascular System
Marine Drugs, 2010 The human genome encodes nine functional voltage-gated Na+ channels. Three of them, namely Nav1.5, Nav1.8, and Nav1.9, are resistant to nanomolar concentrations of tetrodotoxin (TTX; IC50 ≥ 1 μM).
