Male Germline Chromatin
Spermatogenesis requires radical restructuring of germline chromatin at multiple stages, involving coordinated waves of DNA methylation/demethylation, histone modification, and the replacement and removal that occurs before, during, and after meiosis. This Special Issue will draw together papers that address all aspects of chromatin organization and dynamics in the male germ line, in humans, and in model organisms. In particular, we will invite authors to discuss novel methods for studying germline chromatin structure, the interplay between chromatin structure and susceptibility to DNA damage and mutation, chromatin modifications associated with epigenetic inheritance in the early embryo, and the impact this work has for understanding natural fertility and improving assisted reproduction techniques.

Natural Capital and Exploitation of the Deep Ocean
The deep ocean is by far the planet's largest biome and holds a wealth of potential natural assets. Human exploitation of the deep ocean is rapidly increasing whilst becoming more visible to many through the popular media, particularly film and television. The scientific literature of deep-sea exploitation and its effects has also rapidly expanded as a direct function of this increased national and global interest in exploitation of deep-sea resources, both biological (e.g. fisheries, genetic resources) and non-biological (e.g. minerals, oil, gas, methane hydrate). At the same time there is a growing interest in deep-sea contamination (including plastics), with many such studies featured in high profile scientific journals and covered by global media outlets. However, there is currently no comprehensive integration of this information in any form and these topics are only superficially covered in classic textbooks on deep-sea biology. This concise and accessible work provides an understanding of the relationships between biodiversity and ecosystem functioning, both at the seafloor and in the water column, and how these might be affected as a result of human interaction, exploitation and, ultimately, environmental change. It follows a logical progression from geological and physical processes, ecology, biology, and biogeography, to exploitation, management, and conservation. Natural Capital and Exploitation of the Deep Ocean is aimed at marine biologists and ecologists, oceanographers, fisheries scientists and managers, fish biologists, environmental scientists, and conservation biologists. It will also be of relevance and use to a multi-disciplinary audience of fish and wildlife agencies, NGOs, and government departments involved in deep-sea conservation and management.
Yeast Biotechnology 3.0
Yeasts are truly fascinating microorganisms. Due to their diverse and dynamic activities, they have been used for the production of many interesting products, such as beer, wine, bread, biofuels and biopharmaceuticals. Saccharomyces cerevisiae (bakers' yeast) is the yeast species that is surely the most exploited by man. Saccharomyces is a top choice organism for industrial applications, although its use for producing beer dates back to at least the 6th millennium BC. Bakers' yeast has been a cornerstone of modern biotechnology, enabling the development of efficient production processes for antibiotics, biopharmaceuticals, technical enzymes, and ethanol and biofuels. Today, diverse yeast species are explored for industrial applications, such as e.g. Saccharomyces species, Pichia pastoris and other Pichia species, Kluyveromyces marxianus, Hansenula polymorpha, Yarrowia lipolytica, Candida species, Phaffia rhodozyma, wild yeasts for beer brewing, etc. This Special Issue is focused on recent developments of yeast biotechnology with topics including recent techniques for characterizing yeast and their physiology (including omics and nanobiotechnology techniques), methods to adapt industrial strains (including metabolic, synthetic and evolutionary engineering) and the use of yeasts as microbial cell factories to produce biopharmaceuticals, enzymes, alcohols, organic acids, flavours and fine chemicals, and advances in yeast fermentation technology and industrial fermentation processes.

Women and Plants
This unique collection of in-depth case studies from Latin America, Asia, Africa, Europe and North America demonstrates the importance of women and gender relations in plant genetic resource management and conservation. It provides a state-of-the-art overview of the concepts, relationships and contexts explaining the relatively hidden gender dimensions of people-plant relations. The contributors come from a rich range of disciplines including ethnobotany, geography, agronomy, anthropology, plant breeding, nutrition and development economics. They demonstrate how crucial women are to plant biodiversity management and conservation at household, village, and community levels; and how gender relations have a strong influence on the ways in which local people understand, manage, and conserve biodiversity. Continued access to biological resources is crucial to rural women's status and welfare, and their motivations therefore are a principal driving force countering processes of biological erosion. The contributors highlight the gender biases evident in much contemporary scientific research, policy and development practice. And they seek to contribute to a number of important debates, including the determinants of genetic erosion, the significance of gender in indigenous ethno-botanical knowledge systems, indigenous intellectual property rights systems and women's entitlements therein, and ecofeminist and other debates about the nature of gender-environment relations.

Visual Perception, Signal Processing, & Associated Eye Diseases
The book describes the mechanism of vision initiated by photo-transduction, through a biochemical cascade that regulates the activity of ion channels in the membrane of the photoreceptor's outer segment, and thereby the number of neurotransmitters the photoreceptor releases. The signal sent to the visual centers in the brain is highly processed when it leaves the retina, emphasizing those aspects of the visual scene that convey the most significant information. Adaptation to light & dark is discussed. The most common Human Eye Diseases are mentioned with emphasize on the major alterations of the retinal tissue.

Threats
"It's a rare author who can combine literary erudition and an easy fluency of style together with expert knowledge of psychology and evolutionary biology. David Barash adds to all this a far-seeing wisdom and a humane decency that shines through on every page. The concluding section on the senseless and dangerous futility of nuclear deterrence theory is an irrefutable tour de force which should be read by every politician and senior military officer. If only!" -- Richard Dawkins From hurricanes and avalanches to diseases and car crashes, threats are everywhere. Beyond objective threats like these, there are also subjective ones: situations in which individuals threaten each other or feel threatened by society. Animals, too, make substantial use of threats. Evolution manipulates threats like these in surprising ways, leading us to question the ethics of honest versus dishonest communication. Rarely acknowledged--and yet crucially important--is the fact that humans, animals, and even plants don't only employ threats, they often respond with counter-threats that ultimately make things worse. By exploring the dynamic of threat and counter-threat, this book expands on many fraught human situations, including the fear of death, of strangers, and of "the other." Each of these leads to unique challenges, such as the specter of eternal damnation, the murderous culture of guns and capital punishment, and the emergence of right-wing nationalist populism. Most worrisome is the illusory security of deterrence, the idea that we can use the threat of nuclear war to prevent nuclear war! Threats are so widespread that we often don't realize how deeply they are ingrained in our minds or how profoundly and counter-productively they operate. Animals, humans, societies, and even countries internalize threats, behind which lie a myriad of intriguing questions: How do we know when to take a threat seriously? When do threats make things worse? Can they make things better? What can we do to use them wisely rather than destructively? In a comprehensive exploration into questions like these, noted scientist David P. Barash explains some of the most important characteristics of life as we know it.
Bin Ich Etwas Besonderes?
Vor etwa 45.000 Jahren haben wir Menschen uns mit der Schaffung von Kultur, Werkzeugen, Symbolik und Kunst von unseren Vorfahren und Urspr羹ngen entfernt. Diese "kognitive Revolution" gab uns das Gef羹hl, dass wir etwas Besonderes sind. Schriftsteller, Wissenschaftler, Philosophen und Religionen staunen seit Jahrtausenden 羹ber unsere Brillanz. Dennoch sind wir mit dem Rest der Natur durch Gene, Anatomie und Physiologie verbunden und in einer gemeinsamen Evolution verwurzelt. Alle Arten sind einzigartig, aber sind wir einzigartiger als andere Tiere? Diese Frage geht an die Wurzel dessen, was wir sind. Doch viele wissenschaftliche Erkenntnisse haben im Laufe der Zeit Zweifel an der Sonderstellung des Menschen aufkommen lassen. Dinge, die wir einst als einzigartig menschlich betrachtet haben, sind es nicht. Wir sind nicht die einzige Spezies, die z.B. Pl瓣ne f羹r die Zukunft schmiedet, vergangene Entscheidungen bereut, um verlorene Leben trauert und Sex aus anderen Gr羹nden als derZeugung von Nachkommen hat.
Redesigning Life
Since the birth of civilisation, human beings have manipulated other life-forms. We have selectively bred plants and animals for thousands of years to maximise agricultural production and cater to our taste in pets. The observation of the creation of artificial animal and plant variants was a key stimulant for Charles Darwin's theory of evolution. The ability to directly engineer the genomes of organisms first became possible in the 1970s, when the gene for human insulin was introduced into bacteria to produce this protein for diabetics. At the same time, mice were modified to produce human growth hormone, and grew huge as a result. But these were only our first tottering steps into the possibilities of genetic engineering. In the past few years, the pace of progress has accelerated enormously. We can now cut and paste genes using molecular scissors with astonishing ease, and the new technology of genome editing can be applied to practically any species of plants or animals. 'Mutation chain reaction' can be used to alter the genes of a population of pests, such as flies; as the modified creatures breed, the mutation is spread through the population, so that within a few generations the organism is almost completely altered. At the same time, scientists are also beginning to synthesize new organisms from scratch. These new technologies hold much promise for improving lives. Genome editing has already been used clinically to treat AIDS patients, by genetically modifying their white blood cells to be resistant to HIV. In agriculture, genome editing could be used to engineer species with increased food output, and the ability to thrive in challenging climates. New bacterial forms may be used to generate energy. But these powerful new techniques also raise important ethical dilemmas and potential dangers, pressing issues that are already upon us given the speed of scientific developments. To what extent should parents be able to manipulate the genetics of their offspring -- and would designer babies be limited to the rich? Can we effectively weigh up the risks from introducing synthetic lifeforms into complex ecosystems? In this extensively revised paperback edition, John Parrington explains the nature and possibilities of these new scientific developments, which could usher in a brave, new world. We must rapidly come to understand its implications if we are to direct its huge potential to the good of humanity and the planet.
Steps in Plant Physiology
Steps in Plant Physiology Basic Concepts is a eighth project of the plant sciences. Botanical knowledge enhances our understanding and appreciation of our world and improves the quality of many people's lives. The basic knowledge of plant physiology, that is necessary for experts in agriculture. Most common processes of plant physiology such as Photosynthesis, Respiration, Nitrogen Fixation, Bio-Fertilizer, Plant Hormones and Enzymes are highlighted. The basic concepts of plant stress is complemented with the presentation of physiological mechanisms against different environmental stresses.Plant growth and development is introduced with the characterization and commercial use of plant growth regulators (PGRS, plant hormones). The present reference book will fulfill the basic needs of students, researchers and academicians.
Reactive Oxygen Species and Male Fertility
Reactive oxygen species (ROS) are inevitable by-products of aerobic cells. A delicate balance between ROS production and antioxidant defences is essential to assure cell function. This requirement is also true for the spermatozoon, the male gamete, with the unique goal of carrying and delivering the paternal genome into the oocyte. Oxidative stress promotes damage in lipids, proteins and DNA of spermatozoa, and this oxidative damage is associated with infertility. The ROS-dependent damage could occur at different stages of the production and maturation of the sperm. On the other hand, low and controlled levels of ROS are necessary to trigger and regulate sperm function. When ejaculated, spermatozoa are incapable of fertilizing the egg. They must reside in the oviduct of the female genital tract to undergo a yet to be understood the biochemical process called capacitation. Once capacitated, the spermatozoon undergoes the exocytotic event called acrosome reaction and fertilize the oocyte. ROS regulate the different molecular mechanisms such as sperm motility, capacitation and acrosome reaction to assure fertilization. This Special Issue includes original research and reviews of literature concerning the role of reactive oxygen species in male reproduction, particularly the role of antioxidants in the regulation of male fertility as well as basic and clinical studies using antioxidant-based strategies for the treatment of male infertility.

This book brings together in one place the methods used to estimate the abundance of individuals in nature. Code and examples for use with the R programming language are included.
Physiological assessment of thyroid hormones and obesity
Obesity is prevalent in our community. In general, approximately, 71.9% of Palestinians of the age group between 25 to 65 years suffer from overweight. This percentage increases the probability of chronic diseases such as hypertension, diabetes and thus further enhance of heart attack and stroke. In Gaza strip, approximately, 43.4% in the same age category suffers from obesity, of which 53.6% females. Therefore, thyroid hormones disorder has been recently linked to obesity. Examination of T4, T3 and TSH is required in obese subjects in an attempt to understand the association of these hormones with obesity. This study brought into focus this risk health problem. The results of this research may draw the attention of the entire spectrum of Palestinian society to consider these results.

Measuring Abundance
Measuring the abundance of individuals and the diversity of species are core components of most ecological research projects and conservation monitoring. This book brings together in one place, for the first time, the methods used to estimate the abundance of individuals in nature. The statistical basis of each method is detailed along with practical considerations for survey design and data collection. Methods are illustrated using data ranging from Alaskan shrubs to Yellowstone grizzly bears, not forgetting Costa Rican ants and Prince Edward Island lobsters. Where necessary, example code for use with the open source software R is supplied. When appropriate, reference is made to other widely used programs. After opening with a brief synopsis of relevant statistical methods, the first section deals with the abundance of stationary items such as trees, shrubs, coral, etc. Following a discussion of the use of quadrats and transects in the contexts of forestry sampling and the assessment of plant cover, there are chapters addressing line-intercept sampling, the use of nearest-neighbour distances, and variable sized plots. The second section deals with individuals that move, such as birds, mammals, reptiles, fish, etc. Approaches discussed include double-observer sampling, removal sampling, capture-recapture methods and distance sampling. The final section deals with the measurement of species richness; species diversity; species-abundance distributions; and other aspects of diversity such as evenness, similarity, turnover and rarity. This is an essential reference for anyone involved in advanced undergraduate or postgraduate ecological research and teaching, or those planning and carrying out data analysis as part of conservation survey and monitoring programmes.
Antitumoral Properties of Natural Products
Cancer is one of the major causes of death worldwide. It is a multifactorial heterogeneous disease characterized by the transformation of normal cells into malignant cells, which acquire an uncontrolled growth, immortality, invasiveness, and ability to form distant metastasis. Natural bioactive molecules may interfere with these processes and inhibit the carcinogenesis process. In this book, new molecules and extracts, mainly derived from plants, have been described as being able to alter tumor cell behavior and target several abnormal molecular pathways in cancer cells. Among different cancer cells, the more studied include those derived from glioblastoma, osteosarcoma, lung, breast and gastric cancer. These natural products could be an attractive source for the development of new preventative and therapeutic agents against cancer. They may be more selective and have weaker adverse effects compared to conventional chemotherapy drugs that are actually used for cancer treatment. Clinical trials are necessary to demonstrate whether the in vitro and in vivo animal data are reproduced in humans before the application of natural products in cancer prevention and treatment.

The Alveolar Epithelium
Alveolar epithelial cells (AECs) of the lung are important contributors to pulmonary immune functions and to pulmonary development and alveolar repair mechanisms following lung injury. AECI, together with the capillary endothelium, form the extremely thin barrier between alveolar air and blood. AECII produce and metabolize the surface-tension lowering and immune-modulating surfactant and are the progentiors of AECI. A great variety of processes rely on their normal functioning, including maintenance of the alveolar barrier; innate immune defense; and processes of differentiation, senescence, apoptosis, and autophagy. The wide range of AEC functions is nicely reflected by the diversity of topics addressed by the four review and eight original articles contained in this Special Issue of the International Journal of Molecular Sciences. Beyond the broad spectrum of topics, the authors of this issue also made use of an impressive variety of analytical methods, thus further illustrating the fascinating diversity of aspects related to AEC biology.
Stem Cells Heterogeneity in Different Organs
This book presents a comprehensive discussion on the heterogeneity existing between different types of stem cells within the same tissue. As the functions of these stem cells vary, this is very important for the application of stem cells in cell therapy. This book describes the many recent developments that have revealed completely different roles of distinct stem cells within the same organ.Stem Cells Heterogeneity in Different Organs provides a timely update on the current information on stem cells heterogeneity in various tissues. It also provides a solid foundation of the history of stem cells from specific tissues and the current applications of this knowledge in regenerative medicine. Taken with its companion volumes, Stem Cells Heterogeneity: Novel Concepts and Stem Cells Heterogeneity in Cancer, this book is essential reading for advanced cell biology students as well as researchers and clinicians working with stem cells.
Biocatalysis
This book introduces readers to industrially important enzymes and discusses in detail their structures and functions, as well as their manifold applications. Due to their selective biocatalytic capabilities, enzymes are used in a broad range of industries and processes. The book highlights selected enzymes and their applications in agriculture, food processing and discoloration, as well as their role in biomedicine. In turn, it discusses biochemical engineering strategies such as enzyme immobilization, metabolic engineering, and cross-linkage of enzyme aggregates, and critically weighs their pros and cons. Offering a wealth of information, and stimulating further research by presenting new concepts on enzymatic catalytic functions in basic and applied contexts, the book represents a valuable asset for researchers from academia and industry who are engaged in biochemical engineering, microbiology and biotechnology.
The Pangenome
This open access book offers the first comprehensive account of the pan-genome concept and its manifold implications. The realization that the genetic repertoire of a biological species always encompasses more than the genome of each individual is one of the earliest examples of big data in biology that opened biology to the unbounded. The study of genetic variation observed within a species challenges existing views and has profound consequences for our understanding of the fundamental mechanisms underpinning bacterial biology and evolution. The underlying rationale extends well beyond the initial prokaryotic focus to all kingdoms of life and evolves into similar concepts for metagenomes, phenomes and epigenomes. The book's respective chapters address a range of topics, from the serendipitous emergence of the pan-genome concept and its impacts on the fields of microbiology, vaccinology and antimicrobial resistance, to the study of microbial communities, bioinformatic applications and mathematical models that tie in with complex systems and economic theory. Given its scope, the book will appeal to a broad readership interested in population dynamics, evolutionary biology and genomics.
Introduction to environmental toxicology
Our mother environment faces copious problems due to rapid urbanization and growing human population. It is necessary for each individual to protect the environmental resources from any toxicants. Rapid urbanization resulted in the construction of numerous industries which majorly affected the natural air, water and soil resources by exposing it to toxic chemicals. It has not only affected the environment alone but also affected many lives of land and aquatic organisms. The book on environmental toxicology deals with topics like significant issues with chemicals, types of toxic substances, carcinogens, mutagens, teratogen, factors influencing toxicity, factors related to the substance, receptor mediated toxicity, transport of toxicants by air and water, bioaccumulation and biomagnifications of toxic materials in food chain, movement of toxins, pesticides, metabolism and biotransformation of pesticides, combined effect of xenobiotics, toxicity testing, estimation of LC50 and adverse and non-adverse effects.
Tetrodotoxin from Marine Puffer Fish and their Biomedical Application
Tetrodotoxin (TTX) is the best known marine toxin because of its frequent involvement in fatal food poisoning, unique chemical structure and specific action of blocking sodium channels of excitable membranes. Tetrodotoxin is a powerful neurotoxin that can cause death early in 60 % of the humans. Human only has to ingest a few milligrams for a fatal reaction to the toxin to occur. Once consumed the toxin blocks the sodium channels in the nerve tissues, ultimately paralyzing the muscle tissue. Curiously, the toxin seems to be synthesised by the fish itself, but by bacteria associated with the fish. The fish has a mutation in its own sodium channels, which makes it resistant to the effect of the toxin.

Biodegradation of Crude Oil
Microorganisms capable of degrading/detoxifying crude oil were isolated from soil compost. The physicochemical parameters of the soil samples that harbor the growth of hydrocarbon utilizing organisms were also determined using standard procedures. The microorganisms isolated in this course of study showed an appreciable degree of degradation of crude oil used. The hydrocarbon utilizing capabilities by the Micrococcus sp., and Bacillus subtilis isolated from soil composts were analyzed. In biodegradation experiment, utilization of substrates by bacterial isolates resulted in increased population densities with simultaneous increase in emulsification index (EI24) value and decrease in residual crude oil concentration. The Fourier transform infrared spectrometry (FTIR) analyses of the residual hydrocarbons in the liquid minimal salt medium at the end of 15 days incubation showed that Micrococcus sp., had the highest degradation rate of 93.7%, while the Bacillus subtilis had biodegradation rate of 87.5% respectively. Oil pollution is worldwide thread to the environment and the remediation of oil contaminated soil, sediments and water is a major challenge for environmental research.

Human Physiology & Pathobiology
Welcome to the exciting and fascinating world of physiology and pathobiology. As an extension to the general health science studies, this book introduces you to the various abnormalities that can occur in humans.The primary motivation for writing this book, "Human Physiology & Pathobiology - A contemporary guide to disease processes" is the lack of a standardized uniformity in the study of pathophysiology to health science students. It is, therefore, my hope, that this book would alleviate the milieu of challenges faced in this discipline. In writing this book, I have also tried to make it vivid, but brief as possible. Since too much brevity may also compromise understanding, the writing has been a bit "liberal" in some sections including some details which are deemed vital for your understanding, and not memorization.Lastly, while this book is intended to be a textbook of general pathobiology and physiology for health science students, medical students and those in other advanced levels of their medical training can use this book for review.
Oxidative Stress in Plant
Plants are continuously exposed to different environmental stress conditions that have a huge impact on agriculture worldwide, consequently leading to massive economic losses. These adverse conditions alter the metabolism of reactive oxygen and nitrogen species (ROS and RNS). High concentrations of these reactive species-that exceed the capacity of antioxidant defense enzymes-disturb redox homeostasis, which can trigger damage to such macromolecules as membrane lipids, proteins, and nucleic acids, ultimately resulting in nitro-oxidative stress and plant cell death. Significant progress has been made to understand how plants persist in these stressful environments which could be vital to improving plant crop yield. This Special Issue "Oxidative Stress in Plants" includes both original research articles and detailed reviews that aim to better understand the nitro-oxidative stress networks in higher plants, and the addressed topics provide updated and new knowledge about ROS and RNS metabolism in plant responses to abiotic stress as well as the modulation of antioxidant systems in the control of ROS production and accumulation.
Consumer Preferences and Acceptance of Meat Products
This Special Issue "Consumer Preferences and Acceptance of Meat Products" demonstrates that the value of different palatability traits has evolved over time. Moreover, consumer acceptance and preference are not solely determined by the inputs of the meat itself, but can also be influenced by various demographic factors. In addition, consumers' views of meat products vary regionally and by species.

Bioactivities of Lentinus Edodes (Berkeley) Pegler Polysaccharides
Lentinus edodes (L. edodes) is the first cultivated edible mushroom in the world and the second most widely used Traditional Chinese Medicine (TCM) mushroom in global market. Its importance is attributed to both its nutritional value and medical application. Some bioactive compounds of L. edodes including phenolic compounds, ergosterol, selenium, eritadenine, vitamins, as well as calcium and minerals have been isolated and characterized. Recently, polysaccharides extracted from fruiting bodies, mycelia and sclerotia of L. edodes have been shown to have numerous activities including antitumor, antioxidant, anti-inflammatory, antiviral, immunomodulatory, hepatoprotective, hypoglycemic, hypocholesterolemia, etc. The present research study aim is an investigation of chemical structures, biological activity and structure-activity relationship of polysaccharides, other than those reported, extracted from the fruiting bodies of L. edodes.Thus, the analysis and evaluation of L. edodes polysaccharides provides a potential opportunity for the discovery of novel therapeutic agents that exhibit beneficial antitumor and immunomodulatory properties.
