Genetics, Evolution, and Conservation of Neotropical Fishes
Fish represent the most ancestral and specious group of vertebrates, and occupy more diverse aquatic environments around the world. Ichthyofauna is extremely diverse, especially in megadiverse countries occupying biogeographical regions such as the Neotropical Region, which covers an extensive area between North and South America. Much of this biodiversity will be extinct, even before science knows any aspect of its biology. Like this, Neotropical fish genetics started in the end of the 70’s with papers studying the chromosomes of Hoplias malabaricus (Family Erythrinidae) and the karyotype variation among three genera of the family Anostomidae. The topic at that time was concentrated in tw...
Application of Fishes as Biological Models in Genetic Studies
Although Gregor Mendel is considered the father of genetics, he has never taken the credit for his principles on heredity. Mendel's treatises, though they were part of the collection of the largest European libraries in the 19th century, were only rediscovered in 1900, 16 years after his death. Mendel's revolutionary ideas would have given greater strength to the formulation of Charles Darwin's ideas about common descent and gradual evolution through natural selection presented in 1859 in "The Origin of Species." However, Darwin was not totally ignorant of the possibility of genetic heredity. He even described “invisible characters” emerging in atavistic situations and named his hypothet...
Chromosome Biology as a Key to Understand Disease Mechanisms, Genome Architecture and Evolution
This topic has been realized, and is in collaboration with Dr. Constanze Pentzold, Post Doctoral Researcher at the Institute of Human Genetics, University Hospital Jena.
Biotecnologia aplicada à saúde - vol. 1
Nesta coleção a intenção foi reunir, em uma obra didática, sucinta e objetiva os fatos mais recentes na literatura com os conhecimentos clássicos dos temas disponíveis em obras separadas. Para se ter todo o escopo de Biotecnologia Aplicada à Saúde e Biotecnologia Aplicada à Agro&indústria, dividimos o primeiro tema em três volumes e o segundo em um, totalizando 4 volumes, sendo que todos os tópicos são abordados nos cursos de pós-graduação em Biociências e Biotecnologia, dentre outros. Seguindo essa direção e no sentido de produção de um livro que seja para o uso de, tanto alunos de graduação quanto os de pós-graduação e para aqueles profissionais que queiram se in...
Judicial institutionalization of integration processes
The focus of this book is the judicial institutionalization of integration processes through the development of dispute settlement mechanisms, more especifically in the Common Market of the South (MERCOSUR), to date, the most important regional bloc in Latin America. The bloc has been in existence since 1991 and has positioned itself as one of the potential regional blocs for trade and investment, while becoming one of the important actors in the international community. However, its achievements have been tainted by the gaps and problems attached to the core foundation of the regional bloc. MERCOSUR has been suffering or experiencing internal disputes and disunity due to its complex and low...
Vascular Surgery
Vascular surgery has experienced remarkable growth and diversification in the last decade, especially with its embracing the disruptive endovascular technological revolution. Vascular surgeons remain the only group of specialists capable of total treatment of patients with vascular disease, providing medical, minimally invasive, and surgical therapy. Although vascular surgeons practice in all areas of the world, practice patterns in different areas naturally have both similarities and differences that reflect both regional patterns of disease, genetic characteristics of local peoples, cultural preferences for treatment, local political and economic situations, different access to resources a...
Evolution, Composition and Regulation of Supernumerary B Chromosomes
Supernumerary B chromosomes (Bs) are dispensable genetic elements found in thousands of species of plants and animals, and some fungi. Since their discovery more than a century ago, they have been a source of puzzlement, as they only occur in some members of a population and are absent from others. When they do occur, they are often harmful, and in the absence of “selfishness”, based on mechanisms of mitotic and meiotic drive, there appears to be no obvious reason for their existence. Cytogeneticists have long wrestled with questions about the biological existence of these enigmatic elements, including their lack of any adaptive properties, apparent absence of functional genes, their origin, sequence organization, and co-evolution as nuclear parasites. Emerging new technologies are now enabling researchers to step up a gear, to look enthusiastically beyond the previous limits of the horizon, and to uncover the secrets of these “silent” chromosomes. This book provides a comprehensive guide to theoretical advancements in the field of B chromosome research in both animal and plant systems.
Repetitive DNA
The experimental data that have been generated using new molecular techniques associated with the completion of genome projects have changed our perception of the structural features, functional implications and evolutionary dynamics of repetitive DNA sequences. This volume of Genome Dynamics provides a valuable update on recent developments in research into multigene families, centromeres, telomeres, microsatellite DNA, satellite DNA, and transposable elements. Each chapter presents a review by distinguished experts and analyzes repetitive DNA diversity and abundance, as well as the impact on genome structure, function and evolution. This publication is targeted at scientists and scholars at every level, from students to faculty members, and, indeed, anyone involved or interested in genetics, molecular evolution, molecular biology as well as genomics will find it a valuable source of up-to-date information.
