Living Embryos: An Introduction to the Study of Animal Development, Revised Second Edition presents the processes of development as seen throughout the animal kingdom. This book discusses the development of the organ systems of vertebrates. Comprised of 41 chapters, this edition starts with an overview of the history of the study of embryology, which is concerned with the process by which the adult arises from the fertilized egg. This text then discusses the role of the sperm in the determination of bilateral symmetry. Other chapters consider the development of the frog in order to give a basis for comparison with other species. This book discusses as well the structure of the hen''s egg and illustrates the various stages of the development of the chick. The final chapter deals with animal evolution, which produces a wide variety of animal forms. Embryologists, zoologists, medical students, graduate students, university lecturers, and teachers will find this book extremely useful.

Living Tissues: An Introduction to Functional Histology discusses the fundamental concepts that are essential in studying organic tissues. The text first deals with the microscopic study of tissues, and then proceeds to talking about the components of tissues. Next, the book details the organization of tissues, along with the differentiation of cells and tissues. The text will be of great use to students of biology related degrees, such as biochemistry, biological engineering, and medicine.

Techniques in Endocrine Research covers the proceedings of the NATO Advanced Study Institute held at Stratford-upon-Avon, England, under the Auspices of the University of Birmingham. The book focuses on the techniques in endocrinology, as well as x-ray crystallography, electron microscopy, and autoradiography. The selection first offers information on x-ray crystallography in hormone research and the separation and significance of hormone containing subcellular particles, including formation of granules, specificity of granule storing capacity, chromaffin cell granules, and adrenergic nerve granules. The book also takes a look at the possibilities for the use of antibody staining techniques in electron microscopy and in the study of neurosecretion. The publication examines problems in the ultrastructure of endocrine glands, with special reference to the mammalian pituitary, autoradiography in endocrine research, and chromatographic methods of separations. The text also ponders on the state, transport, and regulation of hormones in blood; immunochemical methods in hormone research; and interpretation of biochemical techniques. Discussions focus on the state of insulin in human blood, state of pituitary hormones in blood, and transport of thyroxin in blood. The selection is a vital source of information for readers interested in the techniques in endocrinology.

The Foundations of Genetics describes the historical development of genetics with emphasis on the contributions to advancing genetical knowledge and the various applications of genetics. The book reviews the work of Gregor Mendel, his Law of Segregation, and of Ernst Haeckel who suggested that the nucleus is that part of the cell that is responsible for heredity. The text also describes the studies of W. Johannsen on "pure lines," and his introduction of the terms gene, genotype, and phenotype. The book explains the theory of the gene and the notion that hereditary particles are borne by the chromosomes (Sutton-Boveri hypothesis). Of the constituent parts of the nucleus only the chromatin material divides at mitosis and segregates during maturation. Following studies confirm that the chromatin material, present in the form of chromosomes with a constant and characteristic number and appearance for each species, is indeed the hereditary material. The book describes how Muller in 1927, showed that high precision energy radiation is the external cause to mutation in the gene itself if one allele can mutate without affecting its partner. The superstructure of genetics built upon the foundations of Mendelism has many applications including cytogenetics, polyploidy, human genetics, eugenics, plant breeding, radiation genetics, and the evolution theory. The book can be useful to academicians and investigators in the fields of genetics such as biochemical, biometrical, microbial, and pharmacogenetics. Students in agriculture, anthropology, botany, medicine, sociology, veterinary medicine, and zoology should add this text to their list of primary reading materials.
