In this respect, recent research has shown the excitability of cardiac muscle tissue when irradiated with infrared laser light. Likewise, intrinsic muscle function should give place to local thermal gradients, either because of Ca2+-ATPase thermoregulatory mechanisms or, specifically in the skeletal muscle, after intense exercise. Alongside internal thermal gradients, muscle fatigue characterizes by stressful cellular conditions. Similar to stress-like conditions has been documented in myocytes from rats, the emergence of oscillations of important biochemical species 1. We show how a thermal gradient or a thermal pulse influences the dynamics of biochemical oscillations in a simplified biochemical model of muscle fiber and discuss the consequences in a living muscle. For this purpose, each simplified sarcomere behavior is governed according to a modified Sal'nikov model, as proposed in a previous paper 2. 2022 artículo científico 0012-7353 https://www.redalyc.org/articulo.oa?id=49677393012 https://www.redalyc.org/journal/496/49677393012/ https://www.redalyc.org/journal/496/49677393012/html/ https://www.redalyc.org/journal/496/49677393012/49677393012.epub https://www.redalyc.org/journal/496/49677393012/movil 10.15446/dyna.v89n224.101393 en http://www.redalyc.org/revista.oa?id=496 Dyna application/pdf Universidad Nacional de Colombia Dyna (Colombia) Num.224 Vol.89 |
