This book discusses the role of oxidative stress in the reproductive system. The book reviews endogenous sources, methods of determining its levels in body fluid/tissues, the physiological roles of ROS, as well as its negative effects on the human reproductive processes. Also discussed are multiple extrinsic factors that could induce oxidative stress in the reproductive system. This volume covers various clinical pathologies related to the reproductive system that arise from or produce oxidative stress, both in the male and female. The use of antioxidants as a therapeutic measure to keep ROS levels in check are highlighted, describing the outcome of various clinical studies involving antioxidant supplementation in infertile patients. Infertility is a global disease that affects 15-25% of all couples, and oxidative stress arising from a multitude of sources has been implicated as one of the major contributing factors to the decline in human fertility. As such, this book provides an up-to-date review on the significance of ROS in human reproduction.

In modern scholarship the Hebrew Bible represents a collection of books, perhaps even a library of books. Some think that it is a selection of ancient oral traditions that were eventually written down, edited and preserved. Others suggest that the biblical corpus resulted from a merging of regional libraries in ancient Palestine or was the outcome of the Hasmoneans' need to legitimize their rule by claiming ownership of a library of books originating in the Jerusalem temple. No matter how tantalizing these hypotheses are, the implications of a concrete understanding of the origins of the Bible as library or archive are not often fully appreciated by scholars. Textual Memory explores how various disciplines, including Assyriology, biblical studies, archival science and library history, have made sense of the thousands of collections of clay tablets and ancient written material discovered over the past two hundred years in the Middle East. And it raises the question whether the great libraries of Ashurbanipal and Alexandria, among others, are able to suggest models of how the Hebrew Bible came into being. Can the temple libraries in Mesopotamia or Egypt offer us any clues about who decided what should be preserved and why? What have ancient archival practices of careful selection, conservation, classification and dissemination of information to contribute to our understanding of the creation of the Hebrew Bible? Ultimately, this book is a historiographical synthesis of current scholarship on ancient Near Eastern archives and libraries from different disciplinary perspectives. Its purpose is to understand better how we should conceive of the Bible as religious tradition and literary heritage.

This text brings together in one volume two previous books that laid the groundwork for the construction of the entries in Diccionario Griego-Espanol del Nuevo Testamento (Greek-Spanish Dictionary of the New Testament), namely Metodo de Analisis semantico aplicado al griego del Nuevo Testamento (Method of Semantic Analysis applied to the Greek of the New Testament) and Metodologia del Diccionario Griego Espanol del Nuevo Testamento (Methodology of the Greek Spanish Dictionary of the New Testament), by Juan Mateos and Jesus Pelaez. In the introduction and first part of the text, the concepts of dictionary and meaning are defined and a critical analysis of the dictionaries of F. Zorell, W. Bauer (Bauer-Aland) and Louw-Nida is conducted. Their methodologies are examined with the purpose of then presenting a method of semantic analysis and the steps for establishing the semantic formula of the various classes of lexemes, which functions as the basis for determining lexical and contextual meaning. In the second part the necessary steps for composing the dictionary's entries are proposed. The text concludes with an analysis of related lexemes in order to demonstrate the accuracy of the suggested method. For the first time, a carefully developed method of semantic analysis and the corresponding methodology are presented before the construction of the dictionary's entries.

Written in an easy to follow, informal yet scientific style, "Male Infertility" offers invaluable clinical guidelines for physicians and infertility experts and new data and research of great interest to basic scientists, andrologists and embryologists.

In the early 1970's, due to serious epistemological flaws, the demise of traditional New Testament research paradigms became imminent. A new generation of scholars started the search for a fresh approach, based on scientifically sound principles. Working within the stimulating atmosphere of the New Testament Society of South Africa, the author was one of the pioneers in developing a new, multi-dimensional research approach for New Testament studies. The articles in the present volume, written over a period of 25 years, reflect part of this journey, as viewed from a Pauline perspective. Combining the positive aspects of the traditional biblical research paradigms with the important insights of modern linguistics, literary science, semantics and pragmatics, particularly rhetoric, the author investigates the convergence of various influences in Paul's pre-christian career. He proposes new possibilities of understanding Paul's language and style, such as hyperbolical contrasts, typical of his Semitic background. Various aspects of his strategies of persuasion are investigated, such as creating an ethos, vilification, alienation and re-identification. The majority of articles concentrate on central elements in Pauline theology: belief in the resurrection of Jesus, the centrality of grace, the in Christ and related formulae, faith and obedience, justification in Romans, Christian identity, ethics and ethos, as portrayed in Romans.

Providing a comprehensive review of the interactions between exercise and human reproduction, this unique text focuses on both the positive and negative consequences of sport and physical activity on male and female fertility and infertility and the biological mechanisms and processes behind them. Beginning with a review of the structure and function of the male and female reproductive systems as well as fertilization and gestation, the discussion then turns to the physiology and endocrinology of sport and exercise, which is further elaborated in subsequent chapters on the impact of physical activity, hormonal changes, pathologies, and consequences of drug use for active men and women. Additional chapters address related topics, such as the impact of sport on young athletes and developing reproductive potential, physical activity and pregnancy, the use of oral contraceptives in athletes, oxidative stress, and the impact of nutritional deficiencies on athletes' fertility, with a final chapter providing recommendations and therapeutic guidelines for exercise-related reproductive disorders. Covering everything from the fundamental principles of sports physiology and human reproductive potential to the interaction between physical exercise and the endocrinology of the reproductive system, Exercise and Human Reproduction is an authoritative resource for helping clinicians understand how the reproductive system adapts to activity and exercise and offers strategies to avoid potential harm to human reproduction.

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.

The struggle for democratic education had already begun in the early part of the 20th century with people like Z.K. Matthews, long before 1976 or the school boycotts in the early 1980s. In his early teens, Z.K. Matthews questioned many imbalances in education. He also disagreed with many teachers of his time who believed that whites were naturally more clever than blacks. As a young teacher, he had a dream that improved African education would better equip black people to fight for their political rights, and throughout his life as an educator, he worked to fulfil this dream. In fact, many of his students went on to become influential political leaders. Z.K. himself became a respected leader in the ANC, and gave the organisation the idea of the Freedom Charter. Z.K. Matthews' story will serve as inspiration to many young people who have come to realise the value of education. They Fought for Freedom tells the life stories of southern African leaders who struggled for freedom and justice. In spite of the important roles they played in the history of southern Africa, most of these leaders have been largely ignored by the history books. The series tells their stories in an entertaining manner, in clear language and aims to restore them to their rightful place in history.

Das biblische Danielbuch selbst formuliert die Erwartung: "viele werden es durchforschen ..." (Dan 12,4 Lutherubersetzung). Die Geschichte der Danielauslegung in Judentum, Christentum und Islam war im August 2006 in Berlin Gegenstand eines wissenschaftlichen Symposiums, dessen Tagungsbeitrage hier vorgelegt werden. Das Themenspektrum beginnt bei dem biblischen Danielbuch selbst und reicht dann uber die Danielrezeption im hellenistischen Judentum, im Markusevangelium und in der Alten Kirche (Hippolyt, Ephraem der Syrer, Hieronymus, Theodoret) uber Vertreter des Mittelalters (mittelalterliche islamische Literatur, Abravanel, Nikolaus von Lyra) und der Reformationszeit (Luther, Muntzer, Melanchthon, Calvin) bis hin zu Isaac Newton. Texte und Kunstwerke aus allen drei monotheistischen Weltreligionen werden eroertert. Die Aufsatze bilden Einzelstudien, denen in der Regel eine Quelle zugrunde liegt, die entweder aufgrund ihrer Exemplarizitat fur eine Epoche oder aufgrund ihrer Bedeutung als einer wichtigen Station oder eines Wendepunktes in der Rezeptionsgeschichte ausgewahlt wurde. Da bei den meisten behandelten Autoren ihre Danielrezeption zu einem fortlaufenden Kommentar gerinnt, liegt ein besonderes Augenmerk auf der Gattungsgeschichte des biblischen Kommentars.
