For many years reactive oxygen species (ROS) production in biological systems has been considered to be detrimental. However, a pleasant face of ROS has received recently tremendous attention. Indeed, it has been proven that ROS participate in cell signalling, transcription factors regulation and vitagene activation to maintain optimal cellular redox balance and to provide an effective stress adap ...

1. IntroductionRedox biology is a very quickly developing area of modern biological sciences, and roles of redox homeostasis in health and disease have recently received tremendous attention [1–6]. There are a range of redox pairs in cells/tissues responsible for redox homeostasis maintenance/regulation. They include, but are not limited to, NAD+/NADH, NADP+/NADPH, GSSH/GSH (glutathione syst ...

For the last three decades poultry production worldwide has made tremendous progress in terms of quantity and quality of meat and egg production, including improvement of growth rate and feed conversion rate. However, it has been proven that commercial poultry production is associated with a range of stresses including environmental, technological, nutritional, and internal/biological [1,2]. Indee ...

BackgroundRecently, a comprehensive review paper devoted to roles of nano-Se in livestock and fish nutrition has been published in the Nanoscale Research Letters [1]. The authors described in great detail an issue related to nano-Se production and its possible applications in animal industry and medicine. Indeed, it is well established that many molecules presented as nanoparticles have unusual be ...

1. IntroductionIn commercial dairy and beef production, a range of stresses are responsible for economic losses associated with the decreased productive and reproductive performance of cows. It has been shown that at the molecular level, nutritional, technological, environmental and internal stresses lead to the overproduction of free radicals, the disturbance of the redox balance, and oxidative s ...
