It is now generally accepted for a variety of reasons - morphological as well as physiologica- that the visual systems of arthropods provide a suitable model for the study of information proces- sing in neuronal networks.
Prominent progress in molecular biology was only made when it became possible to separate functionally distinct molecules by taking advantage of their biophysical properties.
Although this is basically a translation of the second German edition published in 1970, more recent experimental findings have, in several instances, been incorporated into the text.
This volume is dedicated to the memory of the late Professor WERNER BRAUN, one of the most devoted and active members of the Editorial Board of the Current Topics in Microbiology and Immunology, who passed away, after suffering a heart attack, in November 1972.
General aspects of nucleic acid uptake by mammalian cells have been the subject of several reviews during the last few years (PAGANO, 1970; BHARGAVA and SHANMUGAM, 1971; DUBES, 1971; RYSER, 1967).
This volume represents the proceedings of the 24th Mos- bach Colloquium on "e;Regulation of Transcription and Trans- lation in Eukaryotes"e; which was held April 26-28, 1973, in Mosbach, Germany, under the auspices of the Gesellschaft fiir Biologische Chemie.
When Richard Goldschmidt' coined the term "e;intersexuality"e; in 1915, he intended it to apply to normally dioecious species which exhibit some kind of mixture between male and female characters.
When Budge in the eighth decade of the nineteenth centlll'Y, started his investigations into the origin and development of the lymphatic system, he probably did not expect that these would be the starting-point for disputes that would continue well into our time.
The purpose of this monograph is to bring together in one volume some of the more recent knowledge of the cellular and biochemical constit- uents of sheep's blood.
When WILHELM RUHLAND developed his plan for an Encyclopedia of Plant Physiol- ogy more than three decades ago, biology could still be conveniently subdivided into classical areas.
As plant physiology increased steadily in the latter half of the 19th century, problems of absorption and transport of water and of mineral nutrients and problems of the passage of metabolites from one cell to another were investigated, especially in Germany.
The discovery of the reversible red far-red control of plant growth and development and the subsequent in vivo identification and isolation of the photoreceptor pigment, phyto- chrome, constitutes one of the great achievements in modern biology.
At the 6th International Conference on Plant Growth Substances, held in Carleton University, Ottawa in 1968, it was decided that the 7th should be held in Czecho- slovakia, following an invitation by Dr.
This book summarizes the papers presented at the International Symposium on vascular smooth muscle, organized in combination with the XXV Interna- tional Congress of Physiological Sciences by the German Society of Angiology e.
The Meyerhof Symposium on "e;Molecular Bioenergetics and Macromolecular Biochemistry"e; took place in Heidelberg from the 5th to the 8th of July, 1970.
HERBERT FISCHER Max-Planck-Institut fur Immunbiologie, Freiburg-Zahringen With 3 Figures Ladies and Gentlemen: On behalf of the organizers of the 22nd Mosbach Colloquium, Msrs.
Phenomena as diverse as tuberculin sensitivity, delayed sensitivity to soluble proteins other than tuberculin, contact allergy, homograft rejection, experimental autoallergies, and the response to many microorganisms, have been classified as members of the class of immune reactions known as delayed or cellular hypersensitivity.
Why should there be a handbook of sensory physiology, and if so, why now' The editors have asked this question, marshalled all of the arguments that seemed to speak against their project, and then discovered that most of these arguments really spoke in favor of it: there seemed to be no doubt that the attempt should be made and that it should be made now.
