The DNA sequencing of a series of living organisms has elucidated many biological problems. But the internal atomic and electronic evolution of DNA remains to be mapped in detail. RNA and DNA now appear to be the prime determinants of biological evolution leading to the sudden appearance of novel organism structures and functions that emerge 'ready made' as a surprise to the organism. This has been demonstrated by the manipulation of genes that led to the sudden production of additional complete wings and legs in flies and birds. The study of this internal atomic construction of macromolecules is being investigated at the large electron accelerators such as the MAX IV Synchrotron Radiation Laboratory, Lund University, Sweden.The periodicity of the chemical elements is well known from its iconic Table. Significantly, this periodicity can now be seen to extend to the properties of living organisms. Biological properties as different as: flight, vision, luminescence and regeneration, as well as others, show unexpectedly periodic emergence. They resurface, without previous announcement, in most unrelated plant and animal families and they emerge irrespective of whether the organism is a simple invertebrate or a most complex mammal.Moreover, this periodicity does not necessarily start at the cell or DNA levels but appears initially in crystals and minerals, where it is shown to be a pure atomic and electronic process, e.g. in luminescence and regeneration.The assembled molecular evidence led to the construction of Periodic Tables of living organisms, placing them in a position comparable to the periodicity of the chemical elements. Surprisingly, there are striking resemblances between the periodicities of the chemical elements and those of living organisms. In addition, the two types of Tables increase our insight into the events directing atomic evolution since the periodic law established in chemical elements turns out to be applicable to the periodicity of living organisms. The new Periodic Tables introduce a predictive capacity in biological evolution that before was hardly contemplated.Eric Scerri, from the Department of Chemistry and Biochemistry, California University, Los Angeles, who is the Author of the book 'The Periodic Table. Its Story and its Significance', Oxford University Press, stated in an e-mail that 'Professor Lima-de-Faria's book is wonderful and a pioneering work'.
This book discusses why specific diseases are being targeted for cell-based retinal therapy, what evidence exists that justifies optimism for this approach, and what challenges must be managed in order to bring this technology from the laboratory into routine clinical practice. There are a number of unanswered questions (e.g., surgical approach to cell delivery, management of immune response, optimum cell type to transplant) that very likely are not going to be answered until human trials are undertaken, but there is a certain amount of "de-risking" that can be done with preclinical experimentation. This book is essential reading for scientists, clinicians, and advanced students in stem cell research, cell biology, and ophthalmology.

Educational environments interact with children's unique genetic profiles, leading to wide individual differences in learning ability, motivation, and achievement in different academic subjects - even when children study with the same teacher, attend the same school and follow the same curriculum. This book considers how education can benefit from the recent progress in genetically informative research. The book provides new insights into the origins of individual differences in education traits such as cognitive abilities and disabilities; motivation and personality; behavioural and emotional problems; social functioning; well-being, and academic achievement. Written and edited by international interdisciplinary experts, this book will be of interest to teachers, parents, educational and developmental psychologists, policy makers and researchers in different fields working on educationally-relevant issues.
Topology and Physics of Circular DNA presents comprehensive coverage of the physical properties of circular DNA. The author examines how topological constraints arising from cyclization of DNA lead to distinctive properties that make closed molecules radically different from linear DNA. The phenomenon of supercoiling, its geometric and topological analysis, and the formation of noncanonical structures in circular DNA under the influence of supercoiling are emphasized. The combination of consistent theoretical analysis and detailed treatment of major experimental approaches make Topology and Physics of Circular DNA an important reference volume for biophysicists, biochemists, molecular biologists, and researchers and students who want to expand their understanding of circular DNA.
Volume I of this book provides a comprehensive discussion of the factors involved in regulation of the cell cycle, the general biological properties of growth factors, and the receptor and postreceptor mechanisms of action of these signaling agents. It evaluates the possible role of growth factors in the regulation of proto-oncogene and tumor suppressor gene expression, and the development of neoplastic processes is discussed in detail.
RNAi technology are used for large-scale screens that systematically shut down each gene in the cell, which can help identify the components necessary for a particular cellular process or an event such as cell division. Exploitation of the pathway is also a promising tool in biotechnology and medicine. This book reviews the selective and robust effect of RNAi on gene expression which makes it a valuable research tool, both in cell culture and in living organisms because synthetic dsRNA introduced into cells can induce suppression of specific genes of interest. This book will introduce new technology in the study of RNA interference in microorganisms, plants and animals.

Biology is often viewed today as a bipartisan field, with molecular level genetics guiding us into the future and natural history (including ecology, evolution, and conservation biology, ) chaining us to a descriptive scientific past. In Darwinian Detectives, Norman Johnson bridges this divide, revealing how the tried and true tools of natural history make sense of the newest genomic discoveries. Molecular scientists exploring newly sequenced genomes have stumbled upon quite a few surprises, including that only one to ten percent of the genetic material of animals actually codes for genes. What does the remaining 90-99% of the genome do? Why do some organisms have a much lower genome size than their close relatives? What were the genetic changes that were associated with us becoming human? As molecular biologists uncover these and other new mysteries, evolutionary geneticists are searching for answers to such questions. Norman Johnson captures the excitement of the hunt for our own genetic history. Through lively anecdotes, he explores how researchers detect natural selection acting on genes and what this genetic information tells us about human origins.
Technologies like CRISPR and gene drives are ushering in a new era of genetic engineering, wherein the technical means to modify DNA are cheaper, faster, more accurate, more widely accessible, and with more far-reaching effects than ever before. These cutting-edge technologies raise legal, ethical, cultural, and ecological questions that are so broad and consequential for both human and other-than-human life that they can be difficult to grasp. What is clear, however, is that the power to directly alter not just a singular form of life but also the genetics of entire species and thus the composition of ecosystems is currently both inadequately regulated and undertheorized. In Gene Editing, Law, and the Environment, distinguished scholars from law, the life sciences, philosophy, environmental studies, science and technology studies, animal health, and religious studies examine what is at stake with these new biotechnologies for life and law, both human and beyond.
This book relates how, between 1954 and 1961, the biologist Seymour
Benzer mapped the fine structure of the rII region of the genome of
the bacterial virus known as phage T4. Benzer's accomplishments are
widely recognized as a tipping point in mid-twentieth-century
molecular biology when the nature of the gene was recast in
molecular terms. More often than any other individual, he is
considered to have led geneticists from the classical gene into the
molecular age.

This book presents deliberations on molecular and genomic mechanisms underlying the interactions of crop plants to the abiotic stresses caused by heat, cold, drought, flooding, submergence, salinity, acidity, etc., important to develop resistant crop varieties. Knowledge on the advanced genetic and genomic crop improvement strategies including molecular breeding, transgenics, genomic-assisted breeding, and the recently emerging genome editing for developing resistant varieties in technical crops is imperative for addressing FHNEE (food, health, nutrition, energy, and environment) security. Whole genome sequencing in many of these crops followed by genotyping-by-sequencing has provided precise information regarding the genes conferring resistance useful for gene discovery, allele mining, and shuttle breeding which in turn opened up the scope for 'designing' crop genomes with resistance to abiotic stresses. The ten chapters each dedicated to a technical crop and one chapter devoted to a crop group in this volume elucidate different types of abiotic stresses and their effects on and interaction with the crops; enumerate the available genetic diversity with regard to abiotic stress resistance among available cultivars; illuminate the potential gene pools for utilization in interspecific gene transfer; present brief on classical genetics of stress resistance and traditional breeding for transferring them to their cultivated counterparts; depict the success stories of genetic engineering for developing abiotic stress-resistant crop varieties; discuss on molecular mapping of genes and QTLs underlying stress resistance and their marker-assisted introgression into elite varieties; enunciate different genomics-aided techniques including genomic selection, allele mining, gene discovery, and gene pyramiding for developing adaptive crop varieties with higher quantity and quality of yields, and also elaborate some case studies on genome editing focusing on specific genes for generating abiotic stress-resistant crops.

New Findings Revolutionize Concepts of Gene Function Endogenous small RNAs have been found in various organisms, including humans, mice, flies, worms, fungi, and bacteria. Furthermore, it's been shown that microRNAs acting as cellular rheostats have the ability to modulate gene expression. In higher eukaryotes, microRNAs may regulate as much as 50 percent of gene expression. Regulation of Gene Expression by Small RNAs brings together the pioneering work of researchers who discuss their work involving a wide variety of small RNA regulatory pathways in organisms ranging from bacteria to humans. In addition to exploring the biogenesis and processing of these regulatory RNAs, they also consider the functional importance of these pathways in host organisms. Assisting current and future researchers, this unique groundbreaking work - Provides a suite of cutting-edge resources for the study of microRNA ontology and function Includes a technology guide for those seeking to assay microRNA expression Explores the mechanisms by which microRNAs regulate gene expression in animal cells, including the regulation of gene expression by RNA-mediated transcriptional gene silencing Discusses a fast and low-cost approach for reversing genetic influences in mammals Looks at breakthroughs in the use of microRNA-based therapy for HIV and cancer This volume captures the essence of the breadth and excitement surrounding the newly discovered regulatory roles of small RNAs. The powerful new approach in the study of gene function described in this text is leading to some remarkable findings that have the potential to revolutionize our understanding of genetic function and the treatment of diseases otherwise considered intractable.
Cancer threatens the lives of people around the world. Women, in particular, are at risk of certain cancers with a genetic cause. Certain mutations in the BRCA1 and BRCA2 genes put mothers and daughters at risk of breast and ovarian cancers. Unlike many cancers that most commonly occur after age 60, these inheritable cancers threaten women's lives, health and fertility even when they are young, before most would even begin to go for annual mammogram screenings to check for breast cancer. Three Daughters, Three Journeys takes on the biggest health issue of our time from a global perspective with three heroines fighting for their lives against cancer. Marzena, a Polish oncology nurse, has spent her life treating child patients with cancer. Then, she confronts it in her own family and her own body. Kamola, a rural Indian girl, knows she has symptoms of the same disease that took her mother, but feels afraid to discuss it with her father and brothers, knowing her family cannot afford medical treatment. Kamola confides in Dr Rini Mishra, a doctor testing a new treatment called Neelazin, using a bacterial anticancer protein in food, to destroy cancer cells. Selena, a wealthy woman of color in Chicago, finds out about her genetic risks of breast and ovarian cancer. She has a choice of preventative surgery that will save her life but remove any chance of having children. As she meets women who struggle to afford cancer treatment, Selena dedicates her life to providing affordable homes and counseling to families affected by the disease. Although the drug Neelazin is fictional, the possibility of new cancer treatments using bacterial anticancer proteins is being researched now. A problem with the current chemotherapy for cancer treatment is the high toxicity of most of these drugs, as these drugs can enter both normal and cancer cells, though preferably cancer cells, causing the death of normal cells as well that are important in maintaining health. Another problem is that current chemotherapeutic drugs mostly target a single or few key steps that are important for cancer growth and proliferation and inhibit the growth of cancer cells. The cancer cells respond by quickly changing these single targets, thereby becoming resistant to the drugs, as is reflected in stage IV cancer patients. An alternative to chemotherapy would be to exploit the bacterial evolutionary wisdom and use certain proteins that can have preferential entry to cancer cells in order to minimize normal cell toxicity and multiple targets in cancer cells through protein-protein complex formation, thus reducing resistance development in cancer cells. An interesting advantage of protein drugs is to express them as part of food, and some recent research seems to suggest that oral consumption of such foods may allow the therapeutic protein to reach the blood stream to target the cancer. Women with the genetic risk factors could soon have the choice of taking a pill or such anticancer protein-expressing food to treat or prevent cancer, rather than removing the healthy tissue of the breasts and ovaries. Hopefully, they would not have to choose between fertility and survival, as is the implied message in this book, fictional as it is at this time.

This book, first published in 1938, is based on the Muirhead Lectures given at Birmingham University in February and March of 1937. The first half of this book is mainly devoted to an exposition of the principles of genetics, whilst the second half deals with more controversial topics, with the text providing an insight into the ideology of the time. This title will be of interest to students of politics and history.
Recent debate about the ethical and regulatory dimensions of developments in genetics has sidelined societal and cultural aspects, which arguably are indispensable for a nuanced understanding of the complexities of the topic. Regulatory and ethical debates benefit from taking seriously this 'third dimension' of culture, which often determines the configurations and limits of the space within which scientific, ethical and legal debate can take place. To fill this gap, this volume brings together contributions exploring the mutual relationships between genetics, markets, societies and identities in genetics and genomics. It draws upon the recent transdisciplinary debate on how socio-cultural factors influence understandings of 'genetics2.0' and shows how individual and collective identities are challenged or reinforced by cultural meanings and practices of genetics. This book will become a standard reference for everyone seeking to make sense of the controversies and shifts in the field of genetics in the second decade of the twenty-first century.
Colleagues and former students of the late Professor Pritchard (aka Bob), an eminent UK geneticist, have gathered memories about his scientific and personal life. Bob's early, crucial contributions to decipher gene structure and mechanism of recombination in fungi, and those in bacterial physiology and the cell cycle, are briefly summarized. Bob was appointed as a young professor (34 years old) to open a new Department of Genetics at the University of Leicester, a department that thrived under his leadership to become internationally recognized for the quality of its scientific research and teaching. Pritchard's research studies on Microbial Genetics and Physiology and his intellectual leadership were pioneering and instrumental in the development of Molecular Biology and Bacterial Cell Biology.Recollections from the contributors about their interactions with Bob will be enjoyed by anyone interested in the history of Genetics in the UK, during the 1960s and 1970s. To future generations of investigators, they provide insights into how unbiased honesty, humbleness, incisiveness, generosity and friendship are cornerstones for the advancement of human knowledge.The book has been compiled from articles by 26 colleagues, former students and friends of Bob Pritchard, and of his surviving daughter, each from his/her personal viewpoint. They include 17 Professors, 2 Readers, 4 Doctors (all PhD's), 2 politicians and an Attorney, and are citizens of 6 countries (UK-14, USA-5, FR-3, ES-2, IL-1, AU-1). Each chapter has been written independently of the others hence marked differences in length (between 1-10 pp) and style. The 44 photographs were gathered from their personal collections.

Resident Stem Cells and Regenerative Therapy: Sources and Clinical Applications, Second Edition presents the main findings to date and the important factors to be considered when contemplating resident stem cells in regenerative therapies. Chapters on cardiac, brain, neural, liver, kidney, skeletal muscle, bone, pancreatic, skin and lung resident stem cells will assist in defining the level of success that has been achieved and the direction for the road ahead. With contributions from leading laboratories, open questions related to resident stem cells and regenerative therapies will also be presented for debate. In the last several decades, stem cells have greatly impacted the scientific and lay communities, providing huge advances in the treatment of devastating human diseases, including myocardial infarction, diabetes, muscular dystrophy, cystic fibrosis, cirrhosis, and osteoporosis. Alongside debates of induced pluripotent stem cells and embryonic stem cells has been the discovery of adult stem cells in many different tissues. While these organ resident or progenitor stem cells offer prospects to contribute to tissue regeneration, they also present challenges because of the complexity of organ structures.
This is the first detailed assessment of the development and implementation of social policy to deal with the problem of the `mentally deficient' in Britain between 1870 and 1959. Mathew Thomson analyses all the factors involved in the policy-making process, beginning with the politics of the legislature and showing how the demands of central government were interpreted by local authorities, resulting in a wide and varied distribution of medical, institutional, and community care in different parts of the country. The efforts of health professionals, voluntary organizations and the families themselves are considered, alongside questions about the influence of changing concepts of class, gender, and citizenship. The author queries the belief that the policy of segregation was largely unsuccessful, and reveals a hitherto unrecognized system of care in the community. He reframes our understanding of the campaign for sterilization and examines why British policy-makers avoided extremist measures such as the compulsory sterilization introduced in Germany and parts of the US during this period. Thomson shows that the problem of mental deficiency cannot be understood simply in terms of eugenics but must also be considered as part of the process of adjusting to democracy in the twentieth century. |
