Book excerpt: Excerpt from Problems and Methods of Research in Protozoölogy Certain protozoa are of great importance to medical men, espe cially those interested in tropical medicine, and to veterinarians since these organisms may be pathogenic parasites of man or domesticated animals. Hence we find that diseases in man and other animals due to these protozoa are being investigated in medi cal and veterinary schools. In, these investigations attention is directed primarily to the effects of the parasitic invasion on the host and the studies of the parasites themselves are undertaken with particular reference to their relations to the host.

Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from Protozoa in Biological Research Numerous textbooks of varying degrees of excellence for the study of Protozoa are now on the market and should be consulted for a general treatment of these unicellular forms. This volume will not fill such a need, but has been prepared as a result of a discussion by a group of specialists assembled during the summer of 1937 at the Marine Biological Laboratory at Woods Hole, Massachusetts, for the purpose of ascertaining the best means to stimulate further research on these unicellular animals. As a result of these discussions it was decided that one good way to attain our end would be to have a group of specialists in the field Of protozoology prepare a work on research in this field, each specialist to provide a chapter on the subject in which he is best known, and about which he can speak with authority. Our first real difficulty was to select a limited number of topics from a vast number of possibilities, and then to choose the biologists who, in our opinion, were the best men to write these chapters. As can be readily imagined, this opened up a long list of difficulties and led to many vexatious troubles, but the present work, finally, is the Outcome.

Book excerpt: Excerpt from The Protozoa The Protozoa not only claim the interest of the professional naturalist, but also that of a wider circle of nature students who, with the aid of the microscope, have always found here a fascinating field for observation and research. In writing the present volume, embodying a summary of the more recent discoveries concerning these minute animals, I have aimed to keep in mind the needs of the latter class of naturalists, as well as those who search more deeply in the unicellular organisms for the solution of many morphological problems which remain unsolved in the higher animals, or for vital processes which afford a transition from the manifestations of life in its simplest expression to life as seen in the lower forms of invertebrates. The subject-matter of the volume is treated from three points of view: (1) The historical, to which the first chapter is devoted. (2) The comparative, to which five chapters are given: one to the group of Protozoa as a whole, the other four to the main classes. (3) The general, to which three chapters are devoted. One of these is given to the phenomena of old age or senile degeneration in Protozoa and renewal of youth through the union of two individuals, and to the bearing of these phenomena upon sexual reproduction in general. Another is given to the special structures of nuclei and centrosomes of the Protozoa; this, the most technical chapter in the book, is introduced because of the growing importance which the Protozoa have in the problems of cellular biology, especially with those dealing with the origin of the division-centre and its accompanying structures in the cells of the Metazoa. The last chapter is devoted to a consideration of the physiology of the Protozoa, with especial reference to the Protozoa as organisms endowed with the powers of coordination and of adaptation, which up to the present time have eluded physical and chemical analysis.

Download or read book Protozo logy Classic Reprint written by Gary N. Calkins and published by Forgotten Books. This book was released on 2017-12-04 with total page 358 pages. Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from Protozoölogy There is need, furthermore, of caution in studying protozoa under such artificial conditions, for they are extremely sensitive to variations and are readily adapted to new conditions. The reactions, both morphological and physiological, of protozoa under such conditions of study require careful control. The study of protozoa, therefore, even when it is possible to apply bacteriological methods, is fundamentally different from the study of bacteria as at present carried on. The latter, dependent upon growth conditions, colony formation, reactions to media, etc., are essentially physiological and based upon the functions of the organisms. The study of protozoa, on the other hand, is essentially morphological, or based upon the structures of the protozoan cell, and involves the changes in cell structures which an individual undergoes during various phases of vitality. Hence it becomes necessary, first of all, to know the life history of the protozoon and the fundamental modifications which its protoplasm assumes. Modern protozoology, therefore, has demanded as a basis for genera and species of protozoa a knowledge of the complete life cycle, and as a basis for classification not the strue tures of the single cells, but the structures which the protoplasm may assume throughout its entire life history from fertilization to death or until the next fertilization. The present volume, finally, does not aim at being an exhaustive treatise on the protozoa; it aims, rather, to give an introduction to the study of modern protozoo'logy as seen from the author's point of view; and for numerous omissions, incomplete references, etc., he can only plead the excuse of a large subject crowded into a limited space.

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.

This book was released on 2012-09-05 with total page 232 pages. Available in PDF, EPUB and Kindle. Book excerpt: Originally published in German in 1935, this monograph anticipated solutions to problems of scientific progress, the truth of scientific fact and the role of error in science now associated with the work of Thomas Kuhn and others. Arguing that every scientific concept and theory—including his own—is culturally conditioned, Fleck was appreciably ahead of his time. And as Kuhn observes in his foreword, "Though much has occurred since its publication, it remains a brilliant and largely unexploited resource." "To many scientists just as to many historians and philosophers of science facts are things that simply are the case: they are discovered through properly passive observation of natural reality. To such views Fleck replies that facts are invented, not discovered. Moreover, the appearance of scientific facts as discovered things is itself a social construction, a made thing. A work of transparent brilliance, one of the most significant contributions toward a thoroughly sociological account of scientific knowledge."—Steven Shapin, Science
