Drosophila melanogaster (fruit fly) is a highly versatile model with a genetic legacy of more than a century. It provides powerful genetic, cellular, biochemical and molecular biology tools to address many questions extending from basic biology to human diseases. One of the most important questions in biology is how a multi-cellular organism develops from a single-celled embryo. The discovery of the genes responsible for pattern formation has helped refine this question and has led to other questions, such as the role of various genetic and cell biological pathways in regulating the process of pattern formation and growth during organogenesis. The Drosophila eye model has been extensively used to study molecular genetic mechanisms involved in patterning and growth. Since the genetic machinery involved in the Drosophila eye is similar to humans, it has been used to model human diseases and homology to eyes in other taxa. This updated second edition covers current progress in the study of molecular genetic mechanisms of pattern formation, mutations in axial patterning, genetic regulation of growth, and more using the Drosophila eye as a model.

This book provides essential insights into microbial pathogenesis, host-pathogen interactions, and the anti-microbial drug resistance of various human pathogens on the basis of various model organisms. The initial sections of the book introduce readers to the mechanisms of microbial pathogenesis, host-pathogen interactions, anti-microbial drug resistance, and the dynamics of biofilm formation. Due to the emergence of various microbial resistant strains, it is especially important to understand the prognosis for microbial infections, disease progression profiles, and mechanisms of resistance to antibiotic therapy in order to develop novel therapeutic strategies. In turn, the second part of the book presents a comparative analysis of various animal models to help readers understand microbial pathogenesis, host-pathogen interactions, anti-microbial drug discovery, anti-biofilm therapeutics, and treatment regimes. Given its scope, the book represents a valuable asset for microbiologists, biotechnologists, medical professionals, drug development researchers, and pharmacologists alike.

Fungal growths affect both human and animal well-being. Many natural pathogens of laboratory animals alter host physiology, rendering the host unsuitable for experimental uses. While the number and prevalence of few pathogens have declined considerably, many still turn up in laboratory animals and represent unwanted variables in research. Investigators using laboratory animals in biomedical experimentation should be aware of the profound effects that many of these agents can have on research. What does the future hold regarding the natural pathogens of laboratory animals? The selection of an animal model must carefully address issues of the type of human disease to mimic, the parameters to follow, and the collection of the appropriate data to answer those questions being asked. Overall, animal models of fungal infection will continue to deepen our understanding of how these infections occur. This book provides a valuable source of information to biological and biomedical scientists and to clinical and doctoral researchers working in the area of fungal infections and diseases of laboratory animal species.

The content of this book is intended to provide the toxicologist in drug development in the pharmaceutical and biotechnology industries with a broad understanding of bone and its interactions with other organ systems in safety assessments. The book is divided into three parts. The first part describes our current understanding of bone biology and its primary regulatory pathways. Additional chapters address regulatory and study design considerations for incorporating bone end points in toxicology studies, with special consideration being given to juvenile toxicology studies. This is intended to address recent regulatory requirements to evaluate skeletal development for drugs in development for pediatric populations. The second part of the book describes the principal techniques and methods used in bone research; understanding how these end-points are derived is fundamental to their appropriate application. These first two parts of the book provide the background and the means to develop the concepts in part three which describes bone and its interaction with other organ systems. The unique series of chapters in part three, contributed to by key leaders in their respective fields and in bone research, provides a comprehensive collective work. Although constantly evolving, the crosstalk and interaction of the skeleton with several organ systems is now recognized and well documented, such as for the reproductive system, muscle and kidney, while our understanding of the interaction with other organ systems, such as the immune system and CNS, is in its infancy. Recent work highlights the key role of the skeleton in the regulation of energy metabolism and the impact this has on research in metabolic diseases such as obesity and diabetes. The hope is that this book will enlighten many and encourage more to explore the impact of new compounds on the skeleton in the development of effective and safe drugs.

Pancreatic islets make up the endocrine pancreas and they contain the only source of insulin in the body, beta cells. Hence, access to high quality preparations of pancreatic islets is fundamental for in vitro studies and to test pre-clinical applications in animal models in vivo. Access to healthy human islets is also crucial to improve transplantation procedures for diabetes. Given the susceptibility of pancreatic islets to the enzymatic digestion and mechanical stress required to obtain them, the isolation of islets is often considered as the delicate "work of a craftsman". This book, which is aimed at beginners and experts alike, is a survey of the current state-of-the-art in this field and it centres on the challenges, pitfalls and peculiarities of pancreatic islet isolation in the different species used in pre-clinical and clinical applications. It explores the similarities and differences between human islets and those from other relevant species (rodents, pigs and non-human primates), and how these influence islet isolation. The ultimate goal of this book is to improve the outcome of islet isolation and transplantation in pre-clinical and clinical applications.

This book highlights the potential advantages of using marine invertebrates like tunicates, echinoderms, sponges and cephalopods as models in both biological and medical research. Bioactive compounds found in marine organisms possess antibacterial, antifungal, anti-diabetic and anti-inflammatory properties, and can affect the immune and nervous systems. Despite substantial research on the medicinal attributes of various marine invertebrates, they are still very much underrepresented in scientific literature: the majority of cell, developmental and evolutionary scientific journals only publish research conducted on a few well-known model systems like Drosophila melanogaster or Xenopus laevis. Addressing that gap, this book introduces readers to new model organisms like starfish or nemertera. By showing their benefits with regard to regeneration, stem cell research and Evo-Devo, the authors provide a cross-sectional view encompassing various disciplines of biological research. As such, this book will not only appeal to scientists currently working on marine organisms, but will also inspire future generations to pursue research of their own.

Mechanisms controlling aggressive behavior started to be identified from late 20's of the 20th century and subsequent research described such mechanisms in great detail. While the findings are of great relevance for the understanding of aggression per se, they provide limited insights into the mechanisms of abnormal aggression i.e. those mechanisms that underlie aggression-related psychopathologies. While basic phenomena and mechanism of aggression are presented, this book is the first that comprehensively describes ultimate and proximate mechanisms that transform normal (laboratory animals) or tolerable (humans) manifestations of aggressiveness into abnormal patterns in laboratory animals and aggression-related psychopathologies in humans. This book is written for behavioral neurobiologists and neuroscientists, interested in emotional control in general and aggression research in particular. The book will also offer important information to neurologists and psychiatrists dealing with aggressive behavior in the clinic and ultimately, may provide means to understand and on the long run to discover novel approaches to the treatment of abnormal human aggression.

This volume provides a transdisciplinary and translational review of many of the leading murine models used to study the mechanisms, mediators and biomarkers linking energy balance to cancer. It provides a review of murine models that should be of interest to basic, clinical and applied research investigators as well as nutrition scientists and students that work in cancer prevention, cancer control and treatment. The worldwide obesity pandemic has been extensively studied by epidemiologic and observational studies and even, in some cases, by randomized controlled trials. However, the development and control of obesity, its comorbidities and its impact on cancer usually occurs over such long periods that it is difficult, if not impossible to conduct randomized controlled trials in humans to investigate environmental contributions to obesity, energy balance and their impact on cancer. In contrast, model organisms, especially mice and rats, provide valuable assets for performing these studies under rigorously controlled conditions and in sufficient numbers to provide statistically significant results. In this volume, many of the leading and new murine models used to study the mechanisms and mediators linking cancer with obesity, sleep, exercise, their modification by environment and how they may continue to be used to further elucidate these relations as well as to explore preclinical aspects of prevention and/or therapeutic intervention are considered. This volume provides an important compilation and analysis of major experimental systems and principles for further preclinical research with translational impact on energy balance and cancer.

The data presented in the book may be helpful for cancer researchers and oncologists.

This manuscript discusses the potentials of the approaches as mentioned below to monitor the AIVs in WMW. Molecular diagnostic platforms enable for accurate detection of the AIVs in the feces of infected birds. Similar technologies can be used to determine the bird species through DNA barcoding, enabling non-invasive research on the epidemiology of the disease. Wild migratory waterfowl (WMW) play significant role in the transmission of avian influenza viruses (AIVs) on large distances. Understanding bird migrations may therefore significantly contribute towards understanding of the disease epidemiology, however most conventional approaches to trace WMW migrations are based on capturing, tagging (mostly ringing or GPS devices) and their re-capturing to link the departure and arrival places. Stable isotope ratios in metabolically inert tissues (feathers, beaks, claws) reflect the ratios present at the point of intake (drinking or feeding), thus enabling for tracing bird origins at stopover places. Molecular diagnostic platforms such as the polymerase chain reaction (PCR) enable for accurate detection of the AIVs in the feces of infected birds. Similar technologies (genetic sequencing) can be used to determine the bird species through DNA barcoding. Simple and easy collection of feather and fecal samples at the stopover places may generate a full information package on which species of WMW carries the AIVs (PCR+DNA barcoding on the feces), as well as the origin of these species (SI+DNA barcoding on the feathers). Therefore, such approaches enable for research on the epidemiology and the ecology of the AIVs in WMW using a non-invasive platform, which does not require capturing of WMW. This manuscript discusses the potentials of these approaches to monitor the AIVs in WMW. p>

This book presents results obtained from the whole mount preparations, radiological, and histological studies of 60 pu/pu and pu/+ mice from late embryo until 3 months of age. Most mice were in the embryo to 6 week age group where vertebral developmental changes are most marked. Although vertebral abnormalities have been identified as due to mutations in the delta-like 3 (Dll3) gene, it is evident that each mouse has differing structural abnormalities. The disorder is analogous to human congenital scoliosis, a common variant of which is spondylocostal dysplasia. The histological studies presented in this book include plastic embedded sections which allow for high level resolution not only of vertebrae, intervertebral discs, and ribs but also of associated spinal cord, nerve roots and ganglia. In addition an overview of embryo and neonatal development in mouse, chick and human vertebrae is provided to better assess how and where deviant pathoanatomy occurs. The book discusses the possible variables involved in creating final deformity beyond the gene abnormality itself.

The information given in this book tries to capture the essence of the sheer dynamicity of the cell along with useful tips on how to address critical rate limiting steps in the process of exploration and investigation of its capacity to regenerate, rebuild and replenish from within. The definitions of stem cells, stemness, and the niche concept continue to undergo revisions. In adult vertebrates, hematopoietic and some non-hematopoietic progenitors are synthesized within specialized niches of bone marrow. They migrate to designated tissues, and are either trans-differentiated or become quiescent and settle down. These form the stem cell niche reservoir in all tissues. Not only the primary hematopoietic tissue but all organs and tissues are also capable of generating progenitors which are either synthesized from these migrants or are direct recruits from other tissues. In the niches, the cells settle down and await their turn to either make more clones like themselves or differentiate and mobilize in an exigency. Thus progenitors are important reserves, to be multiplied and deployed or travel as important message bearing molecules via blood as circulating progenitors which can home to their allocated destinations. Upon reaching, specific integrins and selectins help them “dock” and “port” and they may be reprogrammed to induce further differentiation and help repopulate the denuded tissue. In pulmonary fibrosis and asthma, progenitors from both systemic circulation and local stem cell niches have been found to participate in the myriad ramifications of repair, replacement and regeneration of lost or diseased tissue. Whether they are lung specific or global in origin and role remain to be explored. Research tools, fundamental concepts, techniques, methodologies and standard operating protocols and animal models and human extrapolations, have been discussed in a concise way along with detailed description and discussion on the appropriate rationale to introduce the subject to the casual reader and provide valuable tactical information to the specialist in Regenerative Medicine. I sincerely hope you enjoy the work and appreciate the hard work that has gone into designing and executing elegant experiments by many researchers in the field. The branch is multi-disciplinary and I hope that the readers will not be limited to biologists alone.
