The paratesticular region is a relatively small anatomical compartment containing a disproportionately large number of anatomic structures. In addition to the testicular collecting system there are mesothelial and mesenchymal components representing extensions of the abdominal cavity and retroperitoneum. The epithelial, mesothelial, and connective tissue elements give rise to a wide variety of ...

This is the first volume in a series designed to provide a continuing overview of new experimental procedures and concepts in the field of endocrinology. The editors have gathered a distinguished group of contributors, and some topics, such as "Basic Concepts of Saturation Analysis Techniques" by R. P. Ekins and "Endocrinological Implications of Prostaglandins" by J. D. Flack, P. Ramwell, and J...

Embryology texts are most frequently organized in one of two ways depending on their intended purpose. Undergraduate texts are usually structured such that their sequence mimics the stages of embryolog-ical development. This, of course, makes sense, as it follows the method used by most instructors and allows one to rapidly locate information about a specific event of development. Unless, that ...

Introduction Gastroschisis is a congenital anterior abdominal wall defect, adjacent and usually to the right of the umbilical cord insertion. It occurs as a small, full-thickness periumbilical cleft either immediately adjacent to the umbilicus or separated from it by a strip of skin. This results in herniation of the abdominal contents into the amniotic sac, usually just the small intestine, bu...

this book presents a well-balanced description of the psychiatric team at work.

In a humble, critical manner Dr. Lippman distills his many years of clinical experience into principles and attitudes that are practical lessons f...

Afin d’appréhender les mécanismes qui sous-tendent la physiologie de la vision, la connaissance des bases embryologiques du développement de l’œil et de ses annexes est un prérequis indispensable. La morphogénèse oculaire débute au cours de la quatrième semaine de vie embryonnaire, alors que l’ébauche oculaire s’individualise des diverticules latéraux du cerveau antérieur par des mouvements mor...

of the scientist in the service of the state" we gain but a scant impression of the qualities of the Park we knew, for however true such an epigrammatic statement may be it fails to reveal the genial humanitarian spirit which was the essence of the man. Fortunately, Wade Oliver has made this facet of Park's life a dominant note throughout the pages of the book. The important fact is not that Pa...

The new study has been prompted by indications from researchers at Australia's Casey Station which suggest the subglacial basins could make the East Antarctic ice sheet more vulnerable in a warming world. Satellite data suggest that the Totten Glacier, which dominates the ice of the Aurora subglacial basin, appears to be losing ice at its downstream edge. " We are getting more science done with...

even science whose origins and motives are tainted by sociopolitical influences can be considered "good" or "normal." (This premise is, of course, essential to accept before we are even confronted with the ethical dilemma of whether or not we should use the Nazis' data today.) The problem arises, however, not so much in the theories that are produced by such science as in the application of tho...
