Receptor tyrosine kinases are cell-surface receptors that respond to numerous hormones and growth factors, including insulin, insulin-like growth factors, epidermal growth factor, and nerve growth factor. They activate highly conserved intracellular signaling pathways that regulate cell proliferation, differentiation, and metabolism, playing essential roles in developing and adult animals. This book examines the nature of these receptors and their ligands, the molecular mechanisms that they regulate within cells, and the roles of the receptors in normal physiology and control of embryogenesis. It also discusses how dysfunction of these mechanisms can contribute to cancer and other diseases.

The book has an engaging and lucid style suitable for those entering the field. Students will find ample case studies, illustrations and examples helpful in understanding difficult concepts. Tables, timelines, and maps in every chapter include data summaries and key points. The book highlights peripheral points and background concepts in side boxes for easy reference and lists key ideas at the end of each chapter. This up-to-date and easy to read text is suitable for both classroom study and self-learning.

This book comprehensively covers the topic of COVID-19 and other pandemics and epidemics data analytics using computational modelling. Biomedical and Health Informatics is an emerging field of research at the intersection of information science, computer science, and health care. The new era of pandemics and epidemics bring tremendous opportunities and challenges due to the plentiful and easily available medical data allowing for further analysis. The aim of pandemics and epidemics research is to ensure high-quality, efficient healthcare, better treatment and quality of life by efficiently analyzing the abundant medical, and healthcare data including patient's data, electronic health records (EHRs) and lifestyle. In the past, it was a common requirement to have domain experts for developing models for biomedical or healthcare. However, recent advances in representation learning algorithms allow us to automatically learn the pattern and representation of the given data for the development of such models. Medical Image Mining, a novel research area (due to its large amount of medical images) are increasingly generated and stored digitally. These images are mainly in the form of: computed tomography (CT), X-ray, nuclear medicine imaging (PET, SPECT), magnetic resonance imaging (MRI) and ultrasound. Patients' biomedical images can be digitized using data mining techniques and may help in answering several important and critical questions related to health care. Image mining in medicine can help to uncover new relationships between data and reveal new and useful information that can be helpful for scientists and biomedical practitioners. Assessing COVID-19 and Other Pandemics and Epidemics using Computational Modelling and Data Analysis will play a vital role in improving human life in response to pandemics and epidemics. The state-of-the-art approaches for data mining-based medical and health related applications will be of great value to researchers and practitioners working in biomedical, health informatics, and artificial intelligence..

How do we understand and explain the apparent dichotomy between plasticity and robustness in the context of development? Can we identify these complex processes without resorting to 'either/or' solutions? Written by two leaders in the field, this is the first book to fully unravel the complexity of the subject, explaining that the epigenetic processes generating plasticity and robustness are in fact deeply intertwined. It identifies the different mechanisms that generate robustness and the various forms of plasticity, before considering the functional significance of the integrated mechanisms and how the component processes might have evolved. Finally, it highlights the ways in which epigenetic mechanisms could be instrumental in driving evolutionary change. Essential reading for biologists and psychologists interested in epigenetics and evolution, this book is also a valuable resource for biological anthropologists, sociobiologists, child psychologists and paediatricians.

Advances in our understanding of biological mechanisms have frequently been associated with the development of new techniques. In situ hybridization is a classic case of just such an advance. The technique effectively combines histochemistry with molecular biology and enables the rapid analysis of the distribution of RNA, or DNA, in the tissues. The information gained from this has caused something of a revolution in our understanding of developmental biology, since a fundamental aspect of development is the spatial and temporal expression of genes. In addition the technique has found application in the field of medicine, where it is giving new insights into the functioning of healthy tissues and the diagnosis and study of diseases. This book brings together contributions from leaders in the application of this technique and will help the reader review and be guided through the various options and variations of the technique.

Meristematic cells in plants become the many different types of cells found in a mature plant. This is achieved by a selective response to chemical signals both from neighbouring cells and distant tissues. It is these responses that shape the plant, its time of flowering, the sex of its flowers, its length of survival or progress to senescence and death. How do plants achieve this? This treatise addresses this question using well-chosen examples to illustrate the concept of target cells. The authors discuss how each cell has the ability to discriminate between different chemical signals, determining which it will respond to and which it will ignore. The regulation of gene expression through signal perception and signal transduction is at the core of this selectivity and the Target Cell concept. This volume will serve as a valuable reference for all researchers working in the field of plant developmental biology.

It will be valuable to the novice and experienced worker alike.

This book reflects the state of the art of our understanding of the WNT signaling system, which comprises a network of signaling pathways initiated by the secreted WNT lipoglycoproteins, which are crucial for embryonal development, stem cell regulation, tissue homeostasis and repair. Dysfunction of this evolutionarily conserved signaling system leads to many diseases including developmental disorders, diverse forms of cancer, fibrosis, neurodegenerative disease and many more. The WNT signaling system is built upon 19 mammalian, secreted WNT lipoglycoproteins that interact with a plethora of distinct receptors, such as the G protein-coupled receptors called Frizzleds (FZD1-10), LDL receptor-like proteins (LRP5/6), receptor tyrosine kinases (ROR1, 2, RYK and PTK7). In addition, WNT pathways are tightly regulated by many secreted and cell-intrinsic negative regulators, such as soluble FZD-related proteins (SFRPs), Dickkopfs (DKKs), WNT-inhibitory proteins, TIKI, RNF43 and more. Understanding the basic mechanism in terms of receptor-ligand interaction, receptor selectivity, signal initiation and desensitization remain poorly understood, even though substantial advances have been made the recent years. Due to the involvement of the WNT signaling system in human disease, it appears obvious to target diverse branches pharmacologically and therapeutically. However, given the complexity of the system and its importance for stem cell regulation and tissue maintenance, therapy comes with obvious risks for severe side effects. The field is addressing the challenge to identify suitable targets and selective compounds for therapy allowing disease-selective therapeutic effects and balancing unwanted side effects. This book summarizes the current understanding of the basic and applied pharmacology in the WNT signaling system and bridges disciplines such as pharmacology, physiology, neurosciences, oncology and drug development.

Lastly, the book addresses stem cells from perinatal tissues and their immunoregulatory and differentiation potentials, and summarizes new strategies for targeting cancer stem cells to treat tumors.

The protein molecule is the basic building block of every living entity. Its deficiency leads to restricted growth and development of individuals. Globally, such malnutrition is on the rise due to various reasons such as rapid population growth, stagnation of productivity, and ever-rising costs. Millions of people, especially in developing and under-developed countries, suffer from protein malnutrition and the only possible solution is to encourage farmers to grow high-protein food legume crops in their fields for domestic consumption. This, however, could be possible if farmers are provided with new cultivars with high yield, and resistance to major insects, diseases, and key abiotic stresses. The major food legume crops are chickpea, cowpea, common bean, groundnut, lentil, pigeonpea, and soybean. Predominantly, the legume crops are grown under a subsistence level and, therefore, in comparison to cereals and horticultural crops their productivity is low and highly variable. The crop breeders around the globe are engaged in breeding suitable cultivars for harsh and changing environments but success has been limited and not up to needs. With the recent development of new technologies in plant sciences, efforts are being made to help under-privileged farmers through breeding new cultivars which will produce more protein per unit of land area. In this book, the contributors analyze the constraints, review new technologies, and propose a future course of crop breeding programs in seven cold and warm season legume crops.

'Developmental biology' is widely understood as processes, which mainly concern embryonic animal development and differentiation of cells and tissue. It is also often defined as the timeline for the evolutionary developmental biology of eukaryotic multicellular higher organisms, i.e., plants and animals. The development of prokaryotes and lower eukaryotes in contrary has been neglected for a long time, which was the motivation for publishing this book. This book highlights one of Darwin's most important findings: Evolution is a creative, but not a conscious process. It also illustrates that this concept does not only apply to multicellular higher organisms, but affects every form of life. The reader shall find complex biochemical and genetic pathways of bacteria, yeasts or protozoa, comparable to those exhibited by plants or animals. The molecular mechanisms of dramatic genome rearrangements, recombination and horizontal gene transfer that are responsible for evolutionary adaptations are discussed. Additionally, the book covers bacteria of the genera Myxobacteriales and Caulobacterales, which are able to develop tissue-like cellular organization. The morphogenesis of entomopathogenic fungi and the endosymbiont theory are also addressed. The book is a useful introduction to the field for junior scientists, interested in bacteriology, protistology and fungal development. It is also an interesting read for advanced scientists, giving them a broader view of the field beyond their area of specialization.

Researchers and students in the fields of human genetics, human physiology, developmental biology and biomedical engineering, as well as professionals and scientists in Orthopedics, will particularly find this book helpful.

The mechanisms that control region-specific and axial patterning of cell differentiation during embryogenesis have fascinated experimental biologists for over 100 years. This book describes recent advances in our knowledge of the cellular and molecular mechanisms of pattern formation. The contributors, all active experimentalists, describe research within the two main conceptual frameworks currently employed for analyzing patterning: positional information and induction. The developmental time frame covered extends from the oocyte to developing organ systems, and a wide range of research organisms, from hydrozoans to birds is represented.

For humankind, the most irreducible idea is the concept of life itself. In order to understand that life is essentially an infinite process, transmitted from generation to generation, this book takes the reader on a fascinating journey that unravels one of our greatest mysteries. It begins with the premise that life is a fact-that it is everywhere; that it takes infinite forms; and, most importantly, that it is intrinsically self-perpetuating. Rather than exploring how the first living forms emerged in our universe, the book begins with our first primordial ancestor cell and tells the story of life-how it began, when that first cell diversified into many other cell types and organisms, and how it has continued until the present day. On this journey, the author covers the fundaments of biology such as cell division, diversity, regeneration, repair and death. The rather fictional epilogue even goes one step further and discusses ways how to literally escape the problem of limited recourse and distribution on our planet by looking at life outside the solar system. This book is designed to explain complex ideas in biology simply, but not simplistically, with a special emphasis on plain and accessible language as well as a wealth of hand-drawn illustrations. Thus, it is suitable not only for students seeking for an introduction into biological concepts and terminology, but for everyone with an interest in the fundamentals of life at the crossroad of evolutionary and cell biology.

Global climate change is bound to create a number of abiotic and biotic stresses in the environment, which would affect the overall growth and productivity of plants. Like other living beings, plants have the ability to protect themselves by evolving various mechanisms against stresses, despite being sessile in nature. They manage to withstand extremes of temperature, drought, flooding, salinity, heavy metals, atmospheric pollution, toxic chemicals and a variety of living organisms, especially viruses, bacteria, fungi, nematodes, insects and arachnids and weeds. Incidence of abiotic stresses may alter the plant-pest interactions by enhancing susceptibility of plants to pathogenic organisms. These interactions often change plant response to abiotic stresses. Plant growth regulators modulate plant responses to biotic and abiotic stresses, and regulate their growth and developmental cascades. A number of physiological and molecular processes that act together in a complex regulatory network, further manage these responses. Crosstalk between autophagy and hormones also occurs to develop tolerance in plants towards multiple abiotic stresses. Similarly, biostimulants, in combination with correct agronomic practices, have shown beneficial effects on plant metabolism due to the hormonal activity that stimulates different metabolic pathways. At the same time, they reduce the use of agrochemicals and impart tolerance to biotic and abiotic stress. Further, the use of bio- and nano-fertilizers seem to hold promise to improve the nutrient use efficiency and hence the plant yield under stressful environments. It has also been shown that the seed priming agents impart stress tolerance. Additionally, tolerance or resistance to stress may also be induced by using specific chemical compounds such as polyamines, proline, glycine betaine, hydrogen sulfide, silicon, -aminobutyric acid, -aminobutyric acid and so on. This book discusses the advances in plant performance under stressful conditions. It should be very useful to graduate students, researchers, and scientists in the fields of botanical science, crop science, agriculture, horticulture, ecological and environmental science.

Is it possible that fully differential cells, cells that have acquired specialized functions and perhaps have lost some general properties, can change their nature, becoming cells of another type? Professor Okada has studied this problem extensively and introduced the term "transdifferentiation" to describe the phenomenon. Transdifferentiation is extremely controversial, since it challenges a number of biological orthodoxies. If transdifferentiation really does occur, the process of development and differentiation must be much more flexible than biologists have generally believed. In this book, the author brings together a vast amount of experimental evidence and examines it critically. This discussion clearly establishes that there is a real phenomenon to be explained and that the explanation forces us to change our understanding of a number of basic biological processes. Much of the evidence examined is derived from studies of cell biology but increasingly it has become possible to examine the process at the molecular level. Studies of gene expression provide several promising perspectives on the process of transdifferentiation. Although this monograph focuses on some rather specialized experiments and discusses questions of definition, the phenomenon is so compelling and is of such fundamental importance that postgraduates and researchers in developmental and cell biology, as well as scientists in basic cancer and eye research, will find it equally interesting.

Natural resources and associated biological diversity provide the basis of livelihood for human population, particularly in the rural areas and mountain regions across the globe. Asia is home to the world's highest mountain regions including the Himalayas, Karakorum and Hindukush. These regions are renowned around the globe because of their unique beauty, climate, and biocultural diversity. Because of geoclimatic conditions, the mountains of Asia are medicinal and food plant diversity hot spots. The indigenous communities residing in the valleys of these mountains have their own culture and traditions, and have a long history of interaction with the surrounding plant diversity. Local inhabitants of these mountains areas possess significant traditional knowledge of plant species used as food, medicine, and for cultural purposes. So far, many workers have reported traditional uses of plant species from different regions of Asia including some mountain areas; however, there is not one inclusive document on the ethnobotany of mountains in Asia. This book provides a comprehensive overview on ethno-ecological knowledge and cross cultural variation in the application of plant species among various communities residing in the mountains of Asia; cross cultural variation in traditional uses of plant species by the mountain communities; high value medicinal and food plant species; and threats and conservation status of plant species and traditional knowledge. This book should be useful to researchers of biodiversity and conservation, ethnobiologists, ethnoecologists, naturalists, phytochemists, pharmacists, policy makers, and all who have a devotion to nature.

This book provides a state-of-the-art compendium on the role of proteoglycans and glycosaminoglycans during development and in cancer. It also suggests directions for novel therapeutic and biotechnological applications in stem cell biology. Proteoglycans and glycosaminoglycans, as part of the extracellular matrix, are multifunctional modulators of growth factor, cytokine, integrin and morphogen signaling, which determine both self-renewal, senescence and/or differentiation of stem cells during development. Since proteoglycans modulate cell adhesion and migration they are important organizers of the extracellular matrix within the proper stem cell niche. A malfunctioning of proteoglycans and glycosaminoglycans contributes to the cancer stem cell phenotype, which is linked to therapeutic resistance and recurrence in malignant disease. This book is essential reading for anyone interested in the extracellular matrix and its role in development. The series Biology of Extracellular Matrix is published in collaboration with the American Society for Matrix Biology.

The maximum life span of multicellular organisms varies greatly: for a fruitfly it is about 30 days, for a dog about 20 years, and for a human about 100 years. Despite these differences, all animals show a similar pattern of their life spans - growth, adulthood, and aging, followed by death. The basic cause of aging in multicellular organisms (eukaryotes) lies at the level of the genes, although nutrition and various types of stresses do influence the rate and pattern of aging. This book reviews the molecular biology of the gene in relation to aging. Until about a decade ago it was not possible to probe into the types of changes that occur in eukaryotic genes, due to their enormous complexity. The use of genetic engineering techniques, however, is beginning to unravel the changes that occur in the genes as an organism ages: such as the changing expression of specific genes under normal conditions and under various types of stress, the changes in the regulatory roles of the sequences in the promotor regions of genes, conformational changes that may occur in genes during aging, and the protein factors that are involved in the aging process. The author presents basic information on eukaryotic genes and follows this with details of the changes that occur in their structure and function during aging. He reviews the latest studies being carried out in various laboratories, outlines the gaps and deficiencies in our present knowledge and suggests the most profitable future areas of research. Genes and Aging is for all students and researchers interested in the molecular biology of aging.

Important breakthroughs have recently been made in our understanding of the cognitive and sensory abilities of pollinators: how pollinators perceive, memorise and react to floral signals and rewards; how they work flowers, move among inflorescences and transport pollen. These new findings have obvious implications for the evolution of floral display and diversity, but most existing publications are scattered across a wide range of journals in very different research traditions. This book brings together for the first time outstanding scholars from many different fields of pollination biology, integrating the work of neuroethologists and evolutionary ecologists to present a multi-disciplinary approach. Aimed at graduates and researchers of behavioural and pollination ecology, plant evolutionary biology and neuroethology, it will also be a useful source of information for anyone interested in a modern view of cognitive and sensory ecology, pollination and floral evolution.
