Abstract: Abstract of the thesis entitled EFFECTS OF PERINATAL MALNUTRITION ON BRAIN DEVELOPMENT IN RATS submitted by Wang Ling for the degree of Doctor of Philosophy at The University of Hong Kong in August 2006 The perinatal period, the period around the time of birth, is critical for brain development in most mammalian species. Numerous studies reported in the literature have shown that nutritional insults during this period can cause life-long impairment in various brain functions, including learning and memory function. How perinatal malnutrition leads to impairment in brain learning and memory function is still unclear. An emerging theory suggests that nutritional factors may modulate critical gene expression and subsequently lead to the functional alteration. More resent studies have shown that brain-derived neurotrophic factor (BDNF) plays a crucial role in brain learning and memory function. The objective of the present study was to investigate the effects of perinatal malnutrition on BDNF gene expression in the brain and the effects on spatial learning and memory function. Laboratory rats (Wistar and Sprague-Dawley strains) were used as an animal model. Pregnant or lactating rats were subjected to various types of nutritional insults, including calorie restriction, protein malnutrition or n-3 fatty acid deficiency, and their offspring were evaluated for the spatial learning and memory performance using the Morris water maze test. The concentrations of BDNF and BDNF mRNA in various regions of the brain were determined using enzyme-linked immunosorbent assay (ELISA) and real-time reverse transcription polymerase chain reaction (RT-PCR) respectively. It was found that prenatal 50% calorie restriction significantly reduced the levels of BDNF and its mRNA in hippocampus. Calorie restriction also caused significant impairment in spatial learning ability in the rats. The effects appeared to be proportionate to the duration of prenatal calorie restriction. The effects of perinatal protein malnutrition on spatial learning and memory performance and BDNF gene expression varied in rats depending on the time and duration of the dietary insults. Rats fed with a low protein diet (6% vs. 20% in control) during the four weeks period after birth showed poor spatial learning and memory performance at ten weeks of age accompanied with significant decrease in BDNF and its mRNA concentrations in hippocampus. Rats subjected to the low protein diet two weeks before and four weeks after birth also showed a significantly poor learning and memory performance at four but not ten weeks of age. Moderate decrease in BDNF concentration was observed in the cerebral cortex and hippocampus. Dietary n-3 fatty acid deficiency for three generations led to significant depletion of decosahexaenoic acid (DHA) in the brain tissue. Rats with depleted brain DHA showed dramatic impairment in learning and memory ability at four and ten weeks of age. BDNF mRNA concentration was also significantly reduced in the cerebral cortex and hippocampus in DHA depleted rat pups at four weeks of age. In conclusion, results of the present study indicate that perinatal malnutrition generally reduces BDNF gene expression in the brain and causes impairment in spatial learning and memory performance. Severity of the effect increases with an increased duration of the nu

Available in PDF, EPUB and Kindle. Book excerpt: How we raise young children is one of today's most highly personalized and sharply politicized issues, in part because each of us can claim some level of "expertise." The debate has intensified as discoveries about our development-in the womb and in the first months and years-have reached the popular media. How can we use our burgeoning knowledge to assure the well-being of all young children, for their own sake as well as for the sake of our nation? Drawing from new findings, this book presents important conclusions about nature-versus-nurture, the impact of being born into a working family, the effect of politics on programs for children, the costs and benefits of intervention, and other issues. The committee issues a series of challenges to decision makers regarding the quality of child care, issues of racial and ethnic diversity, the integration of children's cognitive and emotional development, and more. Authoritative yet accessible, From Neurons to Neighborhoods presents the evidence about "brain wiring" and how kids learn to speak, think, and regulate their behavior. It examines the effect of the climate-family, child care, community-within which the child grows.

This book was released on 2013-11-11 with total page 425 pages. Available in PDF, EPUB and Kindle. Book excerpt: Psychologists have long been interested in the problems of children, but in the last 20 years this interest has increased dramatically. The in tensified focus on clinical child psychology reflects an increased belief that many adult problems have their origin in childhood and that early treatment is often more effective than treatment at later ages, but it also seems to reflect an increased feeling that children are inherently important in their own right. As a result of this shift in emphasis, the number of publications on this topic has multiplied to the extent that even full-time specialists have not been able to keep abreast of all new developments. Researchers in the more basic fields of child psychol ogy have a variety of annual publications and journals to integrate research in their areas, but there is a marked need for such an integra tive publication in the applied segment of child and developmental psychology. Advances in Clinical Child Psychology is a serial publication designed to bring together original summaries of the most important developments each year in the field. Each chapter is written by a key figure in an innovative area of research or practice or by an individual who is particularly well qualified to comment on a topic of major contemporary importance. Each author has followed the stan dard format in which his or her area of research was reviewed and the clinical implications of the studies were made explicit.

This book was released on 2020-05-28 with total page 1019 pages. Available in PDF, EPUB and Kindle. Book excerpt: Decades of research have demonstrated that normal aging is accompanied by cognitive change. Much of this change has been conceptualized as a decline in function. However, age-related changes are not universal, and decrements in older adult performance may be moderated by experience, genetics, and environmental factors. Cognitive aging research to date has also largely emphasized biological changes in the brain, with less evaluation of the range of external contributors to behavioral manifestations of age-related decrements in performance. This handbook provides a comprehensive overview of cutting-edge cognitive aging research through the lens of a life course perspective that takes into account both behavioral and neural changes. Focusing on the fundamental principles that characterize a life course approach - genetics, early life experiences, motivation, emotion, social contexts, and lifestyle interventions - this handbook is an essential resource for researchers in cognition, aging, and gerontology.

Available in PDF, EPUB and Kindle. Book excerpt: This book examines the complex impact of prenatal stress and the mechanism of its transmission on children’s development and well-being, including prenatal programming, epigenetics, infl ammatory processes, and the brain-gut microbiome. It analyzes current findings on prenatal stressors affecting pregnancy, including preconception stress, prenatal maternal depression, anxiety, and pregnancy-specific anxieties. Chapters explore how prenatal stress affects cognitive, affective, behavioral, and neurobiological development in children while pinpointing core processes of adaptation, resilience, and interventions that may reduce negative behaviors and promote optimal outcomes in children. Th is complex perspective on mechanisms by which early environmental influences interact with prenatal programming of susceptibility aims to inform clinical strategies and future research targeting prenatal stress and its cyclical impact on subsequent generations. Key areas of coverage include: The developmental effects of prenatal maternal stress on children. Epigenetic effects of prenatal stress. Intergenerational transmission of parental early life stress. The microbiome-gut-brain axis and the effects of prenatal stress on early neurodevelopment. The effect of prenatal stress on parenting. Gestational stress and resilience. Prenatal stress and children’s sleeping behavior. Prenatal, perinatal, and population-based interventions to prevent psychopathology. Prenatal Stress and Child Development is an essential resource for researchers, professors and graduate students as well as clinicians, therapists, and related professionals in infancy and early childhood development, maternal and child health, developmental psychology, pediatrics, social work, child and adolescent psychiatry, developmental neuroscience, and related behavioral and social sciences and medical disciplines. Excerpt from the foreword: “I would make the plea that in addition to anyone with an interest in child development, this book should be essential reading for researchers pursuing “pre-clinical, basic science models of neurodevelopment and brain health”.... This book provides what in my mind is the most advanced compilation of existing knowledge and state-of-the-art science in the field of prenatal psychiatry/psychology (and perhaps in the entire field of prenatal medicine). This volume can brilliantly serve to focus future directions in our understanding of the perinatal determinants of brain health.” Michael J Meaney James McGill Professor of Medicine Translational Neuroscience Programme Adjunct Professor of Paediatrics
