Book Description
Male urogenital glands (also named male accessory sex glands) have received relatively little attention from electron microscopists, with the possible exception of the prostate gland. Moreover, even though comparative studies have clearly shown that these glands exhibit species-dependent features, very few studies, scattered over various publications, are available on the urogenital glands of man. This volume, the 11th of the series on Electron Microscopy in Biology and Medicine, presents an unprecedented collection of information on the functional microanatomy and cytoarchitecture of these organs in humans. Through the integration of transmission and scanning electron microscopy with a variety of modern techniques, it documents the most important aspects of the histophysiology of these glands from their development to some pathological alterations. In order to cover some key mechanisms of their cell biology, such as the action of sex hormones, the epithelio-mesenchymal interactions, and the dynamic of the secretory process, reports on human organs have been supplemented by some studies on experimental animals. The outstanding level of the contributions and the quality of the illustrations make this book, which has been compiled by some of the world authorities on the topic, a work of reference for students, scientists, and professionals interested in biomedical foundations of andrology, as well as a stimulus for future research in this exciting and relatively neglected chapter of human reproduction.

Book Description
Cell biology is moving at breakneck speed, and many of the results from studies on insects have helped in understanding some of the central problems of biology. The time is therefore ripe to provide the scientific community with a series of up-to-date, well illustrated reviews of selected aspects of the sub microscopic cytology of insects. The topics we have included fall into four general groups: seven chapters deal with gametogenesis, four concern develop ing somatic cells, seventeen chapters describe specialized tissues and organs, and three chapters cover cells in pathological states. These accounts are illustrated with over 600 electron micrographs. The more than 1100 pages in the two volumes of Insect Ultrastructure combined labors of 49 dedicated contributors from II countries. represent the These authors have digested and critically summarized a very large body of information, and some measure of this effort can be gained from consulting the bibliographies that close each of the 31 chapters. These contain 2400 publica tions authored by 1500 different scientists. However, before we congratulate ourselves on the advanced state of our knowledge, it is worth remembering that representatives of less than 0.01 % of the known species of insects have been examined with the electron microscope.

Book Description
When STIEVE published his work on male reproductive organs in this handbook in 1930, a definitive treatment of the morphology of the accessory sex glands seemed accomplished. Nevertheless, the increasing bulk of scientific literature published in the last years on this topic has demonstrated that new methods, e. g. , developments in the fields of electron microscopy, cytochemistry and auto radiography, pose new questions. These principally morphological techniques have yielded new insights into the fine structure and functional organization of these glands. The stress, however, lay on biochemical questions concerning the mechanism of hormone action, since the accessory sex glands were considered to be primary target organs of hormone action, i. e. , their cells bind specific hormones. Besides the basic interest of endocrinologists, morphologists, and biochemists, several unanswered questions arose from the practitioners, e. g. , urologists, andrologists, and other clinicians, especially as regards the prostate gland, one of the organs most affected in elderly men. Thus, the epidemiologic investigations of the last years proved this very organ to be one of the most frequent causes of death in elderly men (HANSEN, 1977). The view of the practi tioner established a special field of investigation and effected a shift from morphologic analysis to biochemical or endocrine aspects. Nevertheless, mor phology, if tempered by experimental or concomitant biochemical studies, pro vides a solid base for tracing the pathologic events occurring in these organs.

Book Description
This book has been designed to help medical students succeed with their histology classes, while using less time on studying the curriculum. The book can both be used on its own or as a supplement to the classical full-curriculum textbooks normally used by the students for their histology classes. Covering the same curriculum as the classical textbooks, from basic tissue histology to the histology of specific organs, this book is formatted and organized in a much simpler and intuitive way. Almost all text is formatted in bullets or put into structured tables. This makes it quick and easy to digest, helping the student get a good overview of the curriculum. It is easy to locate specific information in the text, such as the size of cellular structures etc. Additionally, each chapter includes simplified illustrations of various histological features. The aim of the book is to be used to quickly brush up on the curriculum, e.g. before a class or an exam. Additionally, the book includes guides to distinguish between the different histological tissues and organs that can be presented to students microscopically, e.g. during a histology spot test. This guide lists the specific characteristics of the different histological specimens and also describes how to distinguish a specimen from other similar specimens. For each histological specimen, a simplified drawing and a photomicrograph of the specimen, is presented to help the student recognize the important characteristics in the microscope. Lastly, the book contains multiple “memo boxes” in which parts of the curriculum are presented as easy-to-remember mnemonics.

Book Description
The Reproductive Biology of Bats presents the first comprehensive, in-depth review of the current knowledge and supporting literature concerning the behavior, anatomy, physiology and reproductive strategies of bats. These mammals, which occur world-wide and comprise a vast assemblage of species, have evolved unique and successful reproductive strategies through varied anatomical and physiological specialization. These are accompanied by individual and/or group behavioral interactions, usually in response to environmental mechanisms essential to their reproductive success. - Is the first book devoted to the reproductive biology of bats - Contains in-depth reviews of the literature concerned with bat reproduction - Contributors are widely recognized specialists - Provides a powerful database for future research

Book Description
The Physiology of Insect Reproduction provides a comprehensive coverage of insect reproductive system. The title details basic phenomena governing reproductive processes in insects, with the whole spectrum of an insect reproductive cycle. The text first covers insect genitalia, and proceeds to discussing sex determination. Next, the selection talks about the development of unfertilized eggs in insects. The text also deals with gonadal development, along with insect mating behavior. Chapter 7 details the factors that affect egg production and fecundity, while Chapter 8 tackles hormonal control ...
