Abstract

This book contains the proceedings of the International Symposium on the Mechanisms of Sexual Reproduction in Animals and Plants, where many plant and animal reproductive biologists gathered to discuss their recent progress in investigating the shared mechanisms and factors involved in sexual reproduction. This now is the first book that reviews recent progress in almost all fields of plant and animal fertilization. It was recently reported that the self-sterile mechanism of a hermaphroditic marine invertebrate (ascidian) is very similar to the self-incompatibility system in flowering plants. It was also found that a male factor expressed in the sperm cells of flowering plants is involved in gamete fusion not only of plants but also of animals and parasites. These discoveries have led to the consideration that the core mechanisms or factors involved in sexual reproduction may be shared by animals, plants and unicellular organisms. This valuable book is highly useful for reproductive biologists as well as for biological scientists outside this field in understanding the current progress of reproductive biology.

Abstract

Near-Infrared Spectroscopy (NIRS) is a novel and increasingly popular optical imaging technique that has revolutionarized brain research in the youngest developmental populations. After nearly a decade of technological development, NIRS has become a reliable, easy-to-use and efficient tool to explore the linguistic and cognitive abilities of neonates and young infants, opening new vistas for the investigation of language acquisition and cognitive development. This Research Topic covers the latest advances in these areas brought about by NIRS imaging. The main focus is to highlight innovative and foundational studies that go beyond methodological issues and advance our theoretical understanding of infant and child development. Contributions from the pioneers of this method are selected, illustrating how NIRS has allowed developmental researchers to ask theoretically relevant questions that more traditional methods couldn't address. These works further our understanding of language and cognitive development and bring us closer to bridging the gap between brain, mind and behavior at the very beginning of life.

Abstract

Over the past three decades mounting evidence has suggested that infants’ social perceptual and social cognitive abilities are considerably richer than was once thought. By the end of the second year of life, infants discriminate faces along various social dimensions, attend to and understand others’ goals and intentions, use the emotions of others to guide their learning and behavior, attribute dispositional characteristics to other agents, and make basic social evaluations. What has also become clear is that there is a great deal of variability in infants’ social perception and cognition. A critical, outstanding question concerns the nature and meaning of such variability. The proposed Research Topic welcomes papers addressing cutting-edge questions regarding variability and individual differences in early social perception and social cognition. The goal of these papers is to investigate overarching questions in this domain, which are necessary to move the field forward. Variability in early social perception and social cognition (among other domains) in infancy and early childhood is often attributed to noise, or overlooked in favor of focusing on age-related changes. Yet, recent work suggests that variability in social perceptual and social cognitive tasks reliably inter-relates, and predicts real-world social behaviors. For example, infants’ everyday experience with different face categories predicts individual differences in face processing, infants’ production of goal-directed actions predicts their simultaneous understanding of these actions, and variability in social attention during the second year of life is related to theory of mind during the preschool years. These findings suggest that variability in performance on social perception and social cognition tasks is not merely a nuisance variable, but, rather, may provide the key to addressing significant questions regarding the nature of infants’ social perception and social cognition, and the processes that underlie developmental change. Acknowledging and closely examining and investigating variability in early social perceptual and social cognitive abilities may represent a powerful approach for understanding development in (at least) two ways. First, variability can signal transitional points in the developmental onset of a given ability. Thus, such variability, and the extent to which variability relates to experience and/or other abilities, can be used to test hypotheses regarding mechanisms that underlie developmental changes. Second, variability can represent more enduring individual differences between infants. In this case, critical questions arise regarding the source of individual differences (that is, what factors shape the emergence of individual differences?) and whether such early individual differences contribute to the development of more advanced and sophisticated forms of social cognition and behavior. The goal of this Research Topic will be to encourage researchers to take variability in early social perception and cognition seriously. Papers that give variability center stage, and are aimed at addressing the value of variability for identifying developmental mechanisms, as well as investigating the existence, source, and antecedents of early individual differences in social perception and social cognition are welcomed. Taken together, the contributed papers will provide integral new information to the study of social perception and social cognition over the first three years of life.

Abstract

The dementia challenge is the largest health effort of the times we live in. The whole society has to move to a realization of the significance of prioritization to make an attempt in the direction of mental health promotion and dementia risk reduction. New priorities for research are needed to go far beyond the usual goal of constructing a disease course-modifying medication. Moreover, a full empowerment and engagement of men and women living with dementia and their caregivers, overcoming stigma and discrimination should be promoted. The common efforts and the final aim will have to be the progress of a ''dementia-constructive'' world, where people with dementia can take advantage of equal opportunities.

Abstract

Staphylococcus aureus (S. aureus) is a growing issue both within hospitals and community because of its virulence determinants and the continuing emergence of new strains resistant to antimicrobiotics. In this book, we present the state of the art of S. aureus virulence mechanisms and antibiotic-resistance profiles, providing an unprecedented and comprehensive collection of up-to-date research about the evolution, dissemination, and mechanisms of different staphylococcal antimicrobial resistance patterns alongside bacterial virulence determinants and their impact in the medical field. We include several review chapters to allow readers to better understand the mechanisms of methicillin resistance, glycopeptide resistance, and horizontal gene transfer and the effects of alterations in S. aureus membranes and cell walls on drug resistance. In addition, we include chapters dedicated to unveiling S. aureus pathogenicity with the most current research available on S. aureus exfoliative toxins, enterotoxins, surface proteins, biofilm, and defensive responses of S. aureus to antibiotic treatment.

Abstract

""Mechanisms of Neuroinflammation"" book explains how the neuronal cells become swollen at the moment of the blood-brain barrier disruption and how they lose their immunological isolation. A cascade of cytokines and immune cells from the bloodstream enters the nervous system, inflaming neurons and activating the glia. This produces a neuroinflammatory process that can generate different neurodegenerative diseases. Better understanding of mechanisms that are activated at the time when the damage to the brain occurs could lead to the development of suitable therapies that revert the neuronal inflammation and thus prevent further damage to the nervous system.

Abstract

In contemporary understanding, the working areas of children's psychology are expanding considerably. The mental health of the children ensures that they are able to use their developmental abilities, cope with difficulties in life, be productive and be creative, and demonstrate cognitive, emotional, and behavioral characteristics appropriate to their developmental turn. This research was conducted to be able to identify behavioral disorders that may be a sign of children's mental problems and to shed light on the resolution of possible problems by facilitating the follow-up of psychosocial developments during the period of growth. This book presents an overview of the contemporary approaches in the departments of child education and psychology, with the hope of them growing up as happy, peaceful, balanced, thoughtful confident and successful individuals.

Abstract

Among the components of the limbic system, the amygdala is a fascinating structure that is involved in the processes of liking and disliking and in the ways our emotions drive our actions and affect the strength of our memories. Combined with new conceptual breakthroughs, the very latest data obtained by leading world experts in amygdala function that are reviewed in this book have helped to understand how the amygdala contribute to these processes and also to a variety of neurological and neuropsychiatric pathologies. Of course, due to the rate of research advancement, all the chapters presented here correspond to precise questions addressed by experts using highly specific techniques. Therefore, each chapter should be viewed as pieces of a puzzle that represent all the different research areas that have to be taken into consideration in discussing the role of the amygdala in emotion and memory. Although the primary goal of this book is to inform experts and newcomers of some of the latest data in the field of brain structures involved in mechanisms underlying emotional learning and memory, we hope it will also help to stimulate discussion on the functional role of the amygdala and connected brain structures in these mechanisms.
