Nitric Oxide Donors: Biomedical Applications and Perspectives presents the current state of art, challenges and innovations in the design of therapeutics nitric oxide donors with great impact in several aspects of human physiology and pathophysiology. Although considerable innovative progress has been achieved using Nitric Oxide donors in biomedical applications, certain drawbacks still need to be overcome to successfully translate these research innovations into clinical applications. This book encompasses several topics on nitric oxide such as its sources and biological properties; its performance in the cardiovascular and neurologic systems, in the human skin and its application in the treatment of neglected diseases, neurodegenerative disorders, and cancer. Additionally, it covers its role in inflammation and immunity, penile erection function, photodynamic therapy, antimicrobial activities. It also discusses the future of nitric oxide donors in combination with other therapeutic drugs, in implantable sensors, and nitric oxide releasing hydrogels and medical devices for topical applications. The book is a valuable source for researchers on different areas of biomedical field who are interested in the improvements that these molecules can make in the treatment of several conditions.

Several in vitro studies have pointed to the importance of nitric oxide (NO) in the female and male reproductive system in mammals. Its functions vary from preventing oocyte aging, improving the integrity of the microtubular spindle apparatus in aged oocytes, modulating the contraction of the oviduct, to regulating sperm physiology by affecting the motility, inducing chemotaxis in spermatozoa, regulating tyrosine phosphorylation, enhancing the sperm-zona pellucida binding ability, and modulating the acrosomal reaction. In spermatozoa, NO exerts its functions in different ways, which involve key elements such as the soluble isoform of guanylate cyclase, cyclic guanosine monophosphate (cGMP), cyclic adenosine monophosphate (cAMP), protein kinase A (PKA), adenylate cyclase, and the extracellular signal-regulated kinase (ERK) pathway. Furthermore, NO leads to the S-nitrosylation of several sperm proteins, among them a substantial group associated with energy generation and cell movement, but also with signal transduction, suggesting a role for S-nitrosylation in sperm motility and in modulating the sperm function, respectively. In this chapter, an overview of how NO modulates the sperm physiology is presented, based on the knowledge acquired to this day.

Over the last decades, nitric oxide (NO) has emerged as an essential player in redox signalling. Reactive oxygen species (ROS) also act as signals throughout all stages of plant life. Because they are potentially harmful for cellular integrity, ROS and NO levels must be tightly controlled, especially by the classical antioxidant system and additional redox-active metabolites and proteins. Recent work provided evidence that NO and ROS influence each other’s biosynthesis and removal. Moreover, novel signalling molecules resulting from the chemical reaction between NO, ROS and plant metabolites have been highlighted, including N2O3, ONOO-, NO2, S-nitrosoglutathione and 8-NO2 cGMP. They are involved in diverse plant physiological processes, the best characterized being stomata regulation and stress defense. Taken together, these new data demonstrate the complex interactions between NO, ROS signalling and the antioxidant system. This Frontiers in Plant Science Research Topic aims to provide an updated and complete overview of this important and rapidly expanding area through original article and detailed reviews.
