This book discusses the various antioxidants that are in use to overcome oxidative stress in an assisted reproduction setting. Antioxidant therapies may range from enzymatic and non-enzymatic antioxidants, either alone or in combination. While no one antioxidant regime has been identified as effective in improving fertilization and pregnancy rates, antioxidant supplementation has been shown to defend sperm cells from lipid peroxidation and oxidative damage to DNA, and thus improve pregnancy rates. The prevention of oxidative stress and its consequent damage is imperative to ensure a successful outcome of the in vitro fertilization procedure and embryo transfer. Strategies that could be employed to minimize or prevent the detrimental effects of OS during assisted reproduction include supplementation with various types of antioxidants.

This book highlights representatives of emerging new principles in the developmental biology field, such as cell competition, tissue asymmetry, a farewell to classical germ layer theory, and various new insights into tissue morphogenesis and specification based on the most modern experimental approaches. A large-scale paradigm shift occurred in the last decade owing to innovations in powerful live imaging technologies, gene manipulation techniques in developing embryos, and in-depth understanding of signaling systems, among other advances. Comparison between different animal species also highlighted commonalities of underlying principles, which had not been previously recognized. This book represents important elements that caused that paradigm shift, showing typical examples of phenomena or experimental evidence. It has as its mission the highlighting of important problems that currently are being solved, that are yet to be solved, and that are even still emerging. In other words, this book looks to the future based on the most up-to-date knowledge. The authors take an energetic, fresh approach to opening up new horizons, and their work here represents the leading edge of contemporary developmental studies of international repute. Readers—both students and established scientists in the biomedical field—will learn where we are, where the problems are, and which way to go in their understanding of the developmental processes. Stem cell sciences need a solid grounding in real developmental processes. The new principles presented in this book provide important suggestions for designing three-dimensional functional organs in vitro and in other forms, and thus will contribute significantly to the future of stem cell sciences and regenerative medicine.

This authored monograph introduces a genuinely theoretical approach to biology. Starting point is the investigation of empirical biological scaling including their variability, which is found in the literature, e.g. allometric relationships, fractals, etc. The book then analyzes two different aspects of biological time: first, a supplementary temporal dimension to accommodate proper biological rhythms; secondly, the concepts of protension and retention as a means of local organization of time in living organisms. Moreover, the book investigates the role of symmetry in biology, in view of its ubiquitous importance in physics. In relation with the notion of extended critical transitions, the book proposes that organisms and their evolution can be characterized by continued symmetry changes, which accounts for the irreducibility of their historicity and variability. The authors also introduce the concept of anti-entropy as a measure for the potential of variability, being equally understood as alterations in symmetry. By this, the book provides a mathematical account of Gould's analysis of phenotypic complexity with respect to biological evolution. The target audience primarily comprises researchers interested in new theoretical approaches to biology, from physical, biological or philosophical backgrounds, but the book may also be beneficial for graduate students who want to enter this field.
