Book Description
The primates represent a diverse group with the phylogenetic relationships of the var ious species reflected in their early embryonic development. The members of the Tupaiidae, Lemuridae and Lorisidae show great similarities to the lower mammals and even birds. The Tarsiidae represent an intermediate step and the Platyrrhini and Catarrhini exhibit the greatest similarities to man. During the period of embryogenesis, the dimensions of an embryo are insufficient guide to its age and much more reliable information can be derived from a study of its external form and internal structure. Examination of embryological specimens from a variety of simian species dates back to the early 1900's but much of this material was collected in a haphazard way from animals shot in the wild. Heuser and Streeter (1941) depicted a series of embryos of the rhesus monkey (Macaca mulatta) and correlated their gestational age with external form and size. Streeter (1951) arranged human em bryos, between 24. ± 1 and 47. ± 1 days of post-ovulation age, into age groups or devel opmental horizons based on their external form and internal structure. Each horizon was two days apart and numbered XI to XXIII. The transition from embryo to fetus occurred at the end of horizon XXIII and was arbitrarily dermed as the point where bone marrow invaded the cartilaginous precursor in the humerus. The earlier stages I-X have been dermed subsequently, (Heuser and Corner, 1957; O'Rahilly, 1973).

Reproduction in New World Primates
Author: J.P. Hearn
Publisher: Springer Science & Business Media
ISBN: 9400973225
Category : Medical
Languages : en
Pages : 219
Book Description
The New World primates are becoming widely used in scientific and medical work in fields from anthropology to zoology, behaviour to urology. They have unique attributes for studies in cancer, infectious diseases, genetics, virology and reproduction. However, it is only now that their reproductive physiology is being clarified in any depth and this book is a first synthesis of that knowledge. The nine authors involved in this project have presented an up to date account of the major New World species used in biological and medical science. In addition to their distribution and conservation in the wild, essential biological data from laboratory studies are presented on reproductive cycles, gestation length, seasonal breeding, puberty and other factors. The major applications of these species in research are explored. Whenever possible, research workers should steer away from using endangered species in their studies. The New World monkeys used in research in any numbers are still fairly common ~n the wild, yet their greatest advantages are ~n their smalle size and high fecundity. This makes possible the establishment of self sustaining captive breeding colonies at a fraction of the time and cost necessary for the more conventional Old World laboratory primates. Consequently the drain on wild stocks need not be extensive as only breeding nuclei should be necessary.

The Common Marmoset in Captivity and Biomedical Research
Author: Robert P. Marini
Publisher: Academic Press
ISBN: 012811830X
Category : Science
Languages : en
Pages : 572
Book Description
The Common Marmoset in Captivity and Biomedical Research is the first text dedicated exclusively to this species,filling an urgent need for an encyclopedic compilation of the existing information. Sponsored by the AmericanCollege of Laboratory Animal Medicine as part of its authoritative Blue Book series, the book covers the biology,management, diseases, and clinical and research applications of this important species. The common marmoset(Callithrix jacchus) has come of age in the scientific community as a behaviorally complex, cognitively advanced,small, prolific, and easily maintained nonhuman primate with many of the advantages of larger animals, such asmacaques, but without the attendant physical and zoonotic risks. Marmosets are currently being used in diverse areas of inquiry, including vision and auditory research, infectious disease, cognitive neuroscience, behavior, reproductive biology, toxicology and drug development, and aging. Themarmoset genome has been sequenced and there is currently an intensive effort to apply gene editing technologies to the species. The creation of transgenic marmosets will provide researchers with a small nonhuman primatemodel to study a number of poorly understood disorders, like autism. - Presents a complete view of the marmoset, covering their biology and management, diseases and clinical applications, and research applications - Includes contributions from renowned and international authors and editors - Provides the first authoritative and comprehensive treatment of marmosets in biomedical research as part of the ACLAM Series

Genetics of Human Infertility
Author: P.H. Vogt
Publisher: Karger Medical and Scientific Publishers
ISBN: 3318060984
Category : Medical
Languages : en
Pages : 190
Book Description
Infertility affects more than one in ten couples worldwide and is related to highly heterogeneous pathologies sometimes only discernible in the germ line. Its complex etiology often, but not always, includes genetic factors besides anatomical defects, immunological interference, and environmental aspects. Nearly 30% of infertility cases are probably caused only by genetic defects. Thereby experimental animal knockout models convincingly show that infertility can be caused by single or multiple gene defects. Translating those basic research findings into clinical studies is challenging, leaving genetic causes for the vast majority of infertility patients unexplained. Nevertheless, a large number of candidate genes have been revealed by sophisticated molecular methods. This book provides a comprehensive overview on the subject of infertility written by the leading authorities in this field. It covers topics including basic biological, cytological, and molecular studies, as well as common and uncommon syndromes. It is a must-read for human geneticists, endocrinologists, epidemiologists, zoologists, and counsellors in human genetics, infertility, and assisted reproduction.

Mammalian Sexuality
Author: Alan F. Dixson
Publisher: Cambridge University Press
ISBN: 1108699499
Category : Medical
Languages : en
Pages : 405
Book Description
There are more than 6000 species belonging to twenty-seven orders in the Class Mammalia. Comparative studies of this diverse and magnificent array of extant species provide valuable opportunities to formulate and test hypotheses concerning the evolution of reproduction. This is the first book to explore, in depth and breadth, the complex interrelationships that exist between patterns of mating behaviour and the evolution of mammalian reproductive anatomy and physiology. It focuses upon the role that copulatory and post-copulatory sexual selection have played during the evolution of the monotremes, marsupials and placental mammals, and examines the effects of sperm competition and cryptic female choice upon coevolution of the genitalia in the two sexes. In addition, due weight is also given to discussions of the modes of life of mammals, and to the roles played by natural selection and phylogeny in determining their reproductive traits.
