The impacts of specifically experienced external and internal environments upon phylogenetically established pathways of ontogenetic development seem to be responsible for the intra-species variation of organisms.
Much of the recent spectacular progress in the biological sciences can be at- tributed ot the ability to isolate, analyze, and structurally characterize proteins and peptides which are present in cells and cellular organelles in only very small amounts.
This book the second volume in the "e;Springer Series in Biophysics"e; col- lects together contributions to the conference on "e;Biophysics and Syn- chrotron Radiation"e; held in July 86 at Frascati.
Arachidonic acid metabolites are known to playa regulatory role in a number of biological systems, in which they function as microenviron- mental hormones and intracellular signal mediators.
This book is based on the NATO Advanced Research Workshop on "e;Mesenchymal-Epithelial Interactions in Neural Development"e; which was held in Berlin during March 1986.
New methods in immunocytochemistry and hybridization techniques enable the pathologist active in diagnosis to clarify more effectively problems in the classification and prognosis of tumors.
Oral birth in the Australian gastric brooding frog Rheobatrachus sUus 2 Preface I have deliberately chosen the title picture to the preface, which shows the oral birth of a young gastric brooding frog (Rheobatrachus situs), to draw the reader's attention to the preface since I wish to explain why the book was written and illustrated in the way it now appears.
Biotechnology has come to a stage where, by replacing some of the age- old practices of breeding, it can produce novel and improved plants and animals that can better serve human beings and their purposes.
This book should be regarded as the continuation to my previous book Developmental Biology of the Sea Urchin Embryo, edited by the Academic Press in 1973, rather than as a new edition.
normal and pathological mineralization in vertebrates but also with the interesting problems involved in the formation of in- tracellular deposits of calcium oxalate in plants.
need for an interdisciplinary approach to research, although scientifically desirable and laudable, is not easily met by the individual investigator, a statement which I must now qualify lest it be taken as a faint-hearted view of the problems which confront us in this or any other field of disease-orientated re- search.
If, ten years ago, one had been asked to comment on the prospects of peering into the fmest details of biomolecular organization, most electron microscopists would, I suppose at least, have been quite en- thusiastic.
This volume contains the proceedings of the FEBS Sym- posium on the Biochemistry of Membrane Transport, which was held at the Swiss Institute of Technology, Zlirich, July 18-23, 1976.
The early development of the mammalian embryo belongs to a period which, for the student, provides the particularly deep fascination connected with the processes of germination of the fIrst tender buds of life.
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.
