This book was released on 2015-06-17 with total page 156 pages. Available in PDF, EPUB and Kindle. Book excerpt: Schistosomes are human parasites distributed worldwide in tropical and sub-tropical latitudes, especially in developing countries and impoverished regions. These neglected tropical disease (NTD) pathogens causes debilitating illnesses, which include hepatosplenomegaly, hepatic fibrosis, haemorrhagic necrotic ulcerations in the intestinal mucosa, urogenital tract diseases, in addition to cardiopulmonary, renal and neurologic lesions due to egg accumulation in the liver, intestines, uro-genital tissues and other sites. Urogenital schistosomiasis is a risk factor for bladder cancer and increases the risk of transmission of HIV infection. Despite extensive effort to control this NTD over the years, deployment on a considerable scale of commercially available drugs in endemic populations has induced the emergence of resistant isolates and raised the need to identify new targets for alternative therapies. Because of the availability of genomes of the three major species of human schistosomiasis, and through advances in functional genomics and live imaging, studies on schistosomes have now come into focus as models to investigate adaptations to parasitism and developmental biology of trematodes and cestodes, and indeed flatworms and Lophotrochozoans, at large. This Research Topic aims at gathering state-of-art essays on schistosome genetics, genetics, pathobiology and immunobiology. It also aims to highlight advances in understanding of the host-parasite relationship, in paradigms that address this NTD, and to discuss new perspectives and advances in chemotherapy and immunoprophylaxis.

Download or read book The Biology and Evolution of Trematodes written by K. V. Galaktionov and published by Springer Science & Business Media. This book was released on 2013-12-01 with total page 605 pages. Available in PDF, EPUB and Kindle. Book excerpt: The book by K. V. Galaktionov and A. A. Dobrovolskij maintains the tra- tion of monographs devoted to detailed coverage of digenetic tr matodes in the tradition of B. Dawes (1946) and T. A. Ginetsinskaya (1968). In this - spect, the book is traditional in both its form and content. In the beginning (Chapter 1), the authors provide a consistent analysis of the morphological features of all life cycle stages. Importantly, they present a detailed char- terization of sporocysts and rediae whose morphological-functional orga- zation has never been comprehensively described in modern literature. The authors not only list morphological characteristics, but also analyze the functional significance of different morphological structures and hypothesize about their evolution. Special attention is given to specific features of m- phogenesis in all stages of the trematode life cycle. On this basis, the authors provide several original suggestions about the possible origins of morp- logical evolution of the parthenogenetic (asexual) and the hermaphroditic generations. This is followed by a detailed consideration of the various m- phological-biological adaptations that ensure the successful completion of the complex life cycles of these parasites (Chapter 2). Life cycles inherent in different trematodes are subject to a special analysis (Chapter 3). The authors distinguish several basic types of life cycles and suggest an original interpretation of their evolutionary origin. Chapter 4 features the analysis of structure and the dynamics of trematode populations and is unusual for a monograph of this type.
Download or read book Reproduction and Development in Platyhelminthes written by T. J. Pandian and published by CRC Press. This book was released on 2020-01-28 with total page 320 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is a comprehensive elucidation on aspects of reproduction and development in platyhelminthes covering from acoelids to taeniids. With the unique presence of neoblasts, turbellarians serve as a model for studies on cancer and senescence. Of ~ 27,000 species, ~ 77% are parasites; they are harmful to man and his food basket from livestock and fish. The stress hormone, cortisol level is responsible for susceptibility and resistance of the host. In digeneans, the propagatory multiplication potency is retained by all the larval forms and in either direction in sporocyst. The higher clonal diversity, mixing and selection in Second Intermediate Host (SIH) may purge inbreeding depression suffered by the fluke on propagatory multiplication in First Intermediate Host (FIH). Of 12,012 digeneans, 88% may engage 33,014 potential SIH species. They have the choice to select one among the available/awaiting 3.5 host species. The motility of vertebrate host and euryxenic flexibility/scope for selection of SIH species has increased lineage diversification in digeneans. The life cycle of cestodes is divided into aquatic and terrestrial patterns. The former includes (i) oncosphere and (ii) coracidium types and the latter (iii) hexacanth-cysticercoid, (iv) hexacanth-tetrathyridium and (v) hexacanth-cysticercus types. The share for the oncosphere, coracidium and hexacanth types is 17.0, 29.5 and 46.5%, respectively. The staggering fecundity and adoption of the intermediate host in the herbivorous/insectivorous food chain have enriched Taenioidea as the most (2,264) speciose order. Sex specific genes Smed-dmd 1 and macbol have been identified, and neuropeptides and dipeptides are involved in sexualization. Trematodes are unable to parasitize elasmobranchs, as they cannot suck body fluid/blood containing a high level of urea. Relatively higher fecundity supplemented with propagatory multiplication, incorporation of SIH in 88% species, clonal selection in SIH, and euryxenic flexibility and the widest choice for selection of SIH have led to the highest lineage diversification to render digeneans as the most speciose order in Platyhelminthes.
Download or read book Interrelationships of the Platyhelminthes written by D T J Littlewood and published by CRC Press. This book was released on 2014-04-21 with total page 373 pages. Available in PDF, EPUB and Kindle. Book excerpt: Interrelationships of the Platyhelminthes elucidates the role of the flatworms in the animal kingdom. It brings together results from an international group of experts, spanning many disciplines, who give evidence for the phylogeny of flatworms and constituent major taxa. A combined approach, using traditional comparative techniques along with the modern techniques of molecular phylogeny, is utilized to show that the monophyly of the phylum is not fully established, and that the phylum may in fact consist of two groups: the acoels and their relatives, which are basal metazoans, and the Rhabditophora, which is a more derived group.

Book excerpt: Following the completion of the mouse and human genome sequences, a major challengeisthefunctionalcharacterizationofeverymammaliangeneandthedeciph- ing of their molecular interaction network. The mouse offers many advantages for the use of genetics to study human biology and disease, unmatched among other m- mals. Its development, body plan, physiology, behavior, and diseases have much in common, based on the fact that 99% of the human genes have a mouse ortholog. The investigation of gene function using mouse models is based on many years of tech- logical development. In the two decades since gene targeting in murine embryonic stem (ES) cells was first described by Mario Capecchi and colleagues, more than 3000 predesigned mouse mutants have been developed. To date, a variety of mouse mutagenesis techniques, either gene- or phenotype-driven, are used as systematic approaches. The availability of the genome sequence supports gene-driven approaches such as gene-trap and targeted mutagenesis in ES cells, allowing efficient and precise gene disruption. In combination with the use of site-specific DNA recombinases, in particular the Cre/loxP system, gene disruptioncan be directed to specific cell types in conditionalmousemutants. Furthermore,chemicalandtransposonmutagenesisofthe mouse genome enables us to perform phenotype-driven screens for the unbiased identification of phenotype–genotype correlations involved in models of human d- ease. Over the next several years, the mouse genome will be systematically altered, and the techniques for achieving predesigned manipulations will be constantly developed further and improved. The second edition of Gene Knockout Protocols brings together distinguished c- tributorswithextensiveexperienceinthegenetargetingandmousegeneticsfields.

Download or read book Conference Research Topic 16th International Symposium on Schistosomiasis written by Roberta Lima Caldeira and published by Frontiers Media SA. This book was released on 2024-08-28 with total page 188 pages. Available in PDF, EPUB and Kindle. Book excerpt: Schistosomiasis is a major health problem in many tropical areas in the world. This neglected tropical disease is endemic in 78 countries and affects over 250 million worldwide. In 2021 the World Health Organization published the document “Ending the neglect to attain the Sustainable Development Goals: a road map for neglected tropical diseases 2021−2030”, which established as goals for schistosomiasis (i) elimination of the disease as a public health problem in 78 affected countries by 2030, and (ii) elimination of transmission in 25 endemic countries by 2030. However, to achieve these goals, it is necessary to better understand the disease and its dynamics, the parasite's immunobiology, and its relationship with the definitive and intermediate hosts. This will allow for the development of vaccines, more effective/alternative drugs, precise diagnostic methods, and improved strategies to prevent, control, and eventually even eliminate this devastating disease. Since 1987 the Oswaldo Cruz Foundation (Fiocruz, Brazilian Ministry of Health) has organized the International Symposium on Schistosomiasis on a biennial basis. Historically, this symposium brings together approximately 350 people, accounting for world-renowned scientists, public health managers, students, and policymakers, to translate the knowledge generated in research institutions into actions and tools to improve the quality of life of the population affected by schistosomiasis. Unfortunately, due to the COVID-19 pandemic, the symposium had to be postponed. In order to continue the discussion on schistosomiasis in these difficult times, the organizing committee of the event launched a Pre-conference Research topic (Pre-Conference Research Topic: 16th International Symposium on Schistosomiasis) where scientists could share their latest discoveries with the community. With the advent of vaccines and other public health strategies implemented across the globe, we are pleased to announce that The 16th edition of the International Symposium on Schistosomiasis will be held in person between 21 and 23 November 2022, in Ouro Preto, Minas Gerais, Brazil. We would like to invite our colleagues that intend to attend the Symposium to submit their contributions. In addition, submissions from scientists that would not be able to join us in Ouro Preto in November are also welcome.
Download or read book Gene Drives on the Horizon written by National Academies of Sciences, Engineering, and Medicine and published by National Academies Press. This book was released on 2016-08-28 with total page 231 pages. Available in PDF, EPUB and Kindle. Book excerpt: Research on gene drive systems is rapidly advancing. Many proposed applications of gene drive research aim to solve environmental and public health challenges, including the reduction of poverty and the burden of vector-borne diseases, such as malaria and dengue, which disproportionately impact low and middle income countries. However, due to their intrinsic qualities of rapid spread and irreversibility, gene drive systems raise many questions with respect to their safety relative to public and environmental health. Because gene drive systems are designed to alter the environments we share in ways that will be hard to anticipate and impossible to completely roll back, questions about the ethics surrounding use of this research are complex and will require very careful exploration. Gene Drives on the Horizon outlines the state of knowledge relative to the science, ethics, public engagement, and risk assessment as they pertain to research directions of gene drive systems and governance of the research process. This report offers principles for responsible practices of gene drive research and related applications for use by investigators, their institutions, the research funders, and regulators.
Download or read book Human Schistosomiasis written by Peter Jordan and published by Oxford University Press, USA. This book was released on 1993 with total page 486 pages. Available in PDF, EPUB and Kindle. Book excerpt: Human schistosomes (blood flukes) are digenetic trematodes that spend the adult part of their life cycle in humans and a further part in aquatic snails. Despite advances in chemotherapy, schistosomiasis is still a significant infection in the populations of several countries in the tropics. This book replaces a previous volume Schistosomiasis: Epidemiology, Treatment and Control (Heinemann, 1982) by Jordan and Webbe. All chapters have been rewritten by internationally renowned workers. Ultrasound, expected to aid identification of early disease in the field and increase our understanding of its evolution, is discussed in a new chapter. Others, each with an extensive bibliography, review the parasites and their snail intermediate hosts, epidemiology, clinical manifestations and pathology, diagnosis, immunology, drugs and patient management and control. Limitations of the role of chemotherapy in morbidity control are discussed and the need for flexibility in control interventions in the varied epidemiological situations is stressed. An interdisciplinary approach may be necessary to reduce transmission by appropriate measures against the snail intermediate host, and to implement public health measures, including the provision of safe water (with many other medical and social benefits) and health education. This comprehensive volume is for public health workers involved in the prevention and control of the disease, for physicians, and for students and teachers of many disciplines. It also provides a reference book for health planners, social anthropologists, health educators, water and sanitary engineers and others engaged in improving health in the tropics. Physicians in temperate countries will also find it a useful reference book as schistosomiasis, often acute, is being diagnosed more frequently in those returning from holidays in endemic areas.
