Hardback. Condizione: New. The present book is an up-to-date account of the recent advances in the cellular and molecular changes during diverse ovarian functions in amphibians. The ovarian compartments like developing follicles at different stages of growth, atretic follicles, post-ovulatory follicles, corpora atretica, interstitial cells and stroma have been discussed in relation to their changed cellular and molecular attributes vis-a-vis reproductive phases encompassing environmental stress induced variations in the reproductive success and fecundity. Histochemical, ultrastructural, biochemical and molecular biology of oocyte growth, vitellogenesis, steroidogenesis, oocyte maturation, ovulation, post-ovulatory follicular modulation and their endocrine regulation, have been elaborately explained. It provides comprehensive comparative details of basic and applied aspects of amphibian ovary. This book will be of significance to the scientists and students of reproductive biology, biotechnology, conservation biology and environmental toxicology and system biology. This book is of prime importance for conservation of amphibians.…

Taschenbuch. Condizione: Neu. Druck auf Anfrage Neuware - Printed after ordering - The spermatogenesis and spermatozoa of mammals are of funda mental interest to a wide variety of academic and scientific disci plines; zoologists keep up interest in comparative biology of sper matogenesis and spermatozoa in different groups of mammals for determining their phylogenetic interrelationships. Therefore, during the past 15 years, a wealth of reviews and papers have been published on the morphology (including ultrastructure), histochemistry, auto radiography, biochemistry (including immunology), and cell physiol ogy of the seminiferous epithelium including Sertoli cells, spermato genesis and spermatozoa in mammals. Hormonal regulation of sper matogenesis also forms the subject to numerous studies. Research in this area of reproductive biology continues at a remarkable rate, and new and significant information appears daily in a wide range of journals, published symposia, and specialist reviews. The scattered nature of this information makes it difficult for a scientist, student or andrologist to go through even a small fraction of these publications on the biology of spermatogenesis and spermatozoa and so obtain a general oversight of current activity and new advances. Actually, very little attempt has been made previously to summarize and inte grate the vast information which has become available as a result of use of modern techniques of microscopy, surface topography, histo chemistry, autoradiography, biochemistry, biophysics, immunology, molecular biology, in vitro systems, etc. Much-needed interdisciplin ary approach in biology of seminiferous epithelium, spermatogenesis and spermatozoa is very difficult and thus lacking.…

Taschenbuch. Condizione: Neu. Druck auf Anfrage Neuware - Printed after ordering - Both functions of the mammalian ovary, the endocrine and (synthesis and secretion of steroid hormones) and exocrine (production of ova), depend upon the presence and cyclic growth of follicles, as the depletion of primordial follicles from the ovary leads to cessation of these f-unctions or female reproduction in mammals, or to postmenopausal period in humans. Actually, various fertility and sterility problems at the ovarian level are related to follicles. Therefore, a thorough understanding of the biology of ovarian follicles in mammals is of fundamental interest to a wide variety of academic and scientific disciplines. Study of their structure, function, and control involves mor phology, including ultrastructure, cell biology, physiology, endocrinology, biochemis try, immunology, neurobiology and pharmacology. Zoologists take interest in comparative and evolutionary aspects of biology of ovarian follicles in many different groups of mammals. Agricultural scientists and wildlife biologists need a thorough knowledge of the biology of follicles to control more effectively fecundity in domestic animals and endangered species of mammals. Finally, clinical scientists, toxicologists and physicians want to know the normal and pathological features of ovarian follicles in women, especially in relation to health and the regulation of fertility. Having in view the great importance of studying various aspects of biology of ovarian follicles, numerous papers and reviews on several aspects of ovarian follicles are published annually in a wide variety of scientific journals.…

Taschenbuch. Condizione: Neu. Neuware - In 1954, when I obtained my B. Sc. (Honours School) degree in Zoology, I was asked by my advisor, the late Professor Vishwa Nath, to make comparative cytological studies of oogenesis in birds for my M. Sc. (Honours School) thesis submitted to the Panjab University in 1956. Using the classical techniques of cytology, I studied the various aspects of follicle growth and atresia in five species of birds. Professor Vishwa Nath, who himself devoted most of his life to the study of the comparative cytology of gametogenesis in animals, was so much impressed by my findings on avian oogenesis that he asked me to continue my research work for the Ph. D. degree under his supervision. During my research work on avian oogenesis, I became very much interested in further comparative study of ovarian follicles in vertebrates and thus decided to make comparative, morphological and histochemical studies of ovarian follicles in reptiles, birds and mammals. Actually, very little information was available in this regard in 1957 when I started working for the Ph. D. degree. In subsequent years, I and my numerous dedicated and highly motivated M. Sc. and Ph. D. students con tinued to make comparative, morphological, histochemical, biochemical and physiological studies of ovarian follicles in all groups of vertebrates. In connection with the subject of this book, I would like to make special mention of my two brilliant students, namely Dr. S. K. Varma and Dr. R. K.…
