Download or read book The Biology of Twinning in Man written by M. G. Bulmer and published by Clarendon Press. This book was released on 1970 with total page 224 pages. Available in PDF, EPUB and Kindle. Book excerpt: Twins are probably by no means unknown to most people - for instance in the sporting world of my Australian homeland there are quite a number of cases of note - yet very few people understand the biology behind twins. Although this book suffers a good deal from its age - people like Tim Flannery, Tom McMahon, John Rushton, and Michael Laker clearly give evidence that there is something much more "designed" than randomness involved in dizygotic twin frequencies around the world - if you want a basic introduction to the facts about twinning in humans you will get it here without any doubt. Bulmer deals with every aspects of twinning from the frequency of twinning in humans to the liabilities mothers of twins face vis-à-vis those of single children. He also goes into less common detail about the extreme difficulties of higher order multiple births - and provides little-known but easily understandable details about their frequency. Bulmer shows that for most of human history mothers of twins were at huge disadvantages both in terms of their much greater health risks and the low birth mass and short gestation of their children. For this reason, Bulmer shows that only when major health improvements were made could twins compete with singleton children, and he shows this had and has major consequences culturally. Another very interesting sidelight is Bulmer's look at how single birthing evolved as the most productive strategy in humans and other primates (except for the primitive tree shrews). Bulmer compares this with the situation in animals that typically give birth to multiple young. He should, however, have looked at the environmental conditions that encourage singleton births and compare with those animals that give birth to multiple, highly precocial offspring. All in all, though it is certainly dated, "Biology of Twinning in Man" is a simple and useful overview of what most people should know about multiple births in humans.
Download or read book The Physiology of Twinning Classic Reprint written by Horatio Hackett Newman and published by . This book was released on 2015-07-21 with total page 250 pages. Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from The Physiology of Twinning This book deals primarily with the causes and consequences of twinning. In 1917 was published a volume belonging to this series and written by the present author, entitled The Biology of Twins. That volume was limited to twinning in mammals and was largely morphological in character. The word "twins" was viewed broadly so as to include one-egg (monozygotic) as well as two-egg (dizygotic) twins. We now realize that true twinning is essentially a matter of the division of a single egg at various stages of development and that dizygotic twinning is only a case of plural offspring born simultaneously. The present volume is confined to one-egg twinning and, instead of being limited to mammals, includes all known types of complete or partial one-egg twinning in the animal kingdom. In The Biology of Twins very little attention was paid to theories as to the causes of twins or to the interinfluences of twins upon each other. One definite theory, however, was advanced by the writer to account for the curiously unique process of twin-formation in the armadillos. This theory was the first real causal theory of twinning based on facts. Inasmuch as this theory is now supported by a great body of evidence from many sources, the writer, at the risk of appearing too solicitous about matters of priority, feels impelled to lay definite claim to its authorship. This theory is the center and substance of the present book. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.

Download or read book Deliberately Divided written by Nancy L. Segal and published by Rowman & Littlefield. This book was released on 2021-11-08 with total page 521 pages. Available in PDF, EPUB and Kindle. Book excerpt: A 2022 Choice Reviews Outstanding Academic Title Takes the first in-depth look at the New York City adoption agency that separated twins and triplets in the 1960s, and the controversial and disturbing study that tracked the children’s development while never telling their adoptive parents that they were raising a “singleton twin.” In the early 1960s, the head of a prominent New York City Child Development Center and a psychiatrist from Columbia University launched a study designed to track the development of twins and triplets given up for adoption and raised by different families. The controversial and disturbing catch? None of the adoptive parents had been told that they were raising a twin—the study’s investigators insisted that the separation be kept secret. Here, Nancy Segal reveals the inside stories of the agency that separated the twins, and the collaborating psychiatrists who, along with their cadre of colleagues, observed the twins until they turned twelve. This study, far outside the mainstream of scientific twin research, was not widely known to scholars or the general public until it caught the attention of documentary filmmakers whose recent films, Three Identical Strangers and The Twinning Reaction,left viewers shocked, angered, saddened and wanting to know more. Interviews with colleagues, friends and family members of the agency’s psychiatric consultant and the study’s principal investigator, as well as a former agency administrator, research assistants, journalists, ethicists, attorneys, and—most importantly--the twins and their families who were unwitting participants in this controversial study, are riveting. Through records, letters and other documents, Segal further discloses the investigators’ attempts to engage other agencies in separating twins, their efforts to avoid media exposure, their worries over informed consent issues in the 1970s and the steps taken toward avoiding lawsuits while hoping to enjoy the fruits of publication. Segal's spellbinding stories of the twins’ separation, loss and reunion offers readers the behind-the-scenes details that, until now, have been lost to the archives of history.

Download or read book Culture Media Solutions and Systems in Human ART written by Patrick Quinn and published by Cambridge University Press. This book was released on 2014-03-27 with total page 307 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume describes culture media and solutions used in human ART; how they have been developed for in vitro human pre-implantation embryo development, the function and importance of the various components in media and solutions and how they interact, and how the systems in which these are used can influence outcomes. Chapters discuss inorganic solutes, energy substrates, amino acids, macromolecules, cytokines, growth factors, buffers, pH, osmolality, and the interaction of these parameters. The role of incubators and other physical factors are reviewed, along with the relevance and prospects of emerging technologies: morphokinetic analysis using time-lapse imaging and dynamic fluid incubation systems. Results of prospective randomized trials are emphasized to ascertain the added value of these techniques for selecting viable embryos. This comprehensive guide will be invaluable for embryologists, physicians and all personnel involved in the fluid products used in human ART seeking to optimize their successful use of these components.
