Book Description
Hybridization Techniques for Electron Microscopy examines the use of in situ hybridization techniques, including an overview of current perspectives and future developments. The book features in situ methods for fluorescence probes and confocal scanning microscopes. Three in situ hybridization methods for electron microscopes are analyzed: the non-embedded tissue method using ultrathin frozen sections, pre-embedded method, and post-embedded method using material embedded in hydrophilic resin. Positive and negative features are discussed, and clear instructions regarding implementation of techniques are provided. Particular aspects of the techniques are examined in detail, such as preparation of tissue, pretreatment, hybridization procedures, revelation (autoradiography and immunocytology) and checking procedures, in addition to the illustration, interpretation, and discussion of methods and results. The main applications described include virus detection, chromosomal gene mapping, detection of ribosomic nucleic acid, and detection of messenger RNA in animals and plants. Hybridization Techniques for Electron Microscopy is an excellent reference for cytologists, cell biologists, histochemists, cytochemists, molecular endocrinologists, and neuroendocrinologists.

Book Description
This book presents a review of the principle approaches for visualizing DNA and RNA. Using scanning tunneling and atomic force microscopes, the three-dimensional image of the surface of nucleic acids can be seen at atomic-scale resolutions. Spreading methods provide useful details on structural features of isolated molecules, but the major constituent of living matter is water, and the cryomicroscope makes it possible to look at DNA in its aqueous environment. Genes can be detected simultaneously in situ in chromosomes using fluorescent probes, and also at the electron microscopic level. In cells, nucleic acids are localized and quantified by dyes; electron microscopy is used with cytochemical, immunocytological, nuclease, and in situ hybridization methods. The main potential applications for pathological studies are shown with particular aspects such as viral nucleic acids and in situ PCR.

Book Description
The goal of this fascinating new book is to review the diversity of methods available to apply in situ hybridization histochemistry (ISHH) to a variety of experimental questions. This work includes topics such as synthesis and use of nick-translated DNA probes for ISHH, synthesis and use of oligomeric DNA probes for ISHH, and synthesis and use of RNA probes for ISHH. These interesting chapters describe the preparation of different radiolabeled probes for ISHH. They also discuss their respective advantages and limitations, and describe current results based on the use of these various probes. Sections of the text highlight low and high resolution autoradiography for ISHH, the use of biotin-labeled probes for ISHH, as well as the use of ISHH in combination with established anatomical techniques. In Situ Hybridization Histochemistry answers all of your questions regarding the quantification of ISHH. It also provides a practical description of typical protocols, both from molecular biology and histology. Investigators will understand and value this useful, powerful tool-whatever their backgrounds might be.

Book Description
Successful transmission electron microscopy in all of its manifestations depends on the quality of the specimens examined. Biological specimen preparation protocols have usually been more rigorous and time consuming than those in the physical sciences. For this reason, there has been a wealth of scienti c literature detailing speci c preparation steps and numerous excellent books on the preparation of b- logical thin specimens. This does not mean to imply that physical science specimen preparation is trivial. For the most part, most physical science thin specimen pre- ration protocols can be executed in a matter of a few hours using straightforward steps. Over the years, there has been a steady stream of papers written on various aspects of preparing thin specimens from bulk materials. However, aside from s- eral seminal textbooks and a series of book compilations produced by the Material Research Society in the 1990s, no recent comprehensive books on thin specimen preparation have appeared until this present work, rst in French and now in English. Everyone knows that the data needed to solve a problem quickly are more imp- tant than ever. A modern TEM laboratory with supporting SEMs, light microscopes, analytical spectrometers, computers, and specimen preparation equipment is an investment of several million US dollars. Fifty years ago, electropolishing, chemical polishing, and replication methods were the principal specimen preparation me- ods.

Book Description
Plants interact with a large number of microoganisms which have a major impact on their growth either by establishing mutually beneficial symbiotic relationships or by developing as pathogens at the expense of the plant with deleterious effects. These microorganisms differ greatly not only in their nature (viruses, phytoplasmas, bacteria, fungi, nematodes, ... ) but also in the way they contact, penetrate and invade their host. Histology and cytology have brought an essential contribution to our knowledge of these phenomena. They have told us for instance, how specialized structures of the pathogen are often involved in the adhesion and penetration into the plant, how the interface between both organisms is finely arranged at the cellular level, or what structural alterations affect the infected tissues. They have thus set the stage for the investigations of the underlying molecular mechanisms could be undertaken. Such investigations have been remarkably successful in the recent years, expanding considerably our understanding of plant-microorganism interactions in terms of biochemical changes, rapid modifications of enzymatic activities, coordinated gene activation, signal reception and transduction. Biochemistry, molecular biology and cellular physiology have taken precedence in the phytopathologist's set of methods.

Book Description
The great strides made in the field of morphological methods during the past decades have perhaps found their most spectacular expression in the functional exploration of the nervous system. In comparison with other tissues, nerve tissue displays three kinds of specificity : structural, because of the unique organization of the neuronal networks ; chemical as shown, for example, by the informative molecules exchanged between the nerve cells, and of course functional, thanks to the particular metabolic and electrophysiological characteristics of the neurons. Although for a long time the structural properties of the nervous system were generally considered to constitute the only field to which morphological techniques could be applied, we are to-day justified in believing that they can also explore the nerve tissue through its specific chemical and functional aspects, thanks to the development of immunocytochemistry and in situ hybridization, to the elaboration of the deoxyglucose method, to the use of voltage or ion sensitive dyes, and to the progress made in the application of in vivo techniques like PET. These methods have evolved so fast, the technical and fundamental problems they raise are so numerous and stimulating, and the importance of the complementary data they provide is so obvious, that we thought it was a good time to organize a new meeting between distinguished specialists in the neurocytochemical field.

Book Description
Electron Microscopy of Plant Cells serves as manual or reference of major modern techniques used to prepare plant material for transmission and scanning electron microscopy. There have been other books that generally discuss electron microscope methodology. This book focuses on problem areas encountered through the presence of tough cell walls and large central vacuole. It details preparative techniques for botanical specimens. Each of the nine chapters of this book covers the basic principles, useful applications, and reliable procedures used on the method of electron microscopy. Other topics discussed in each chapter include the general preparation and straining of thin sections, quantitative morphological analysis, and enzyme cytochemistry. This book also explains the immunogold labelling, rapid-freezing methods, and ambient- and low-temperature scanning electron microscopy among others. This book will be invaluable to general scientists, biologists, botanists, and students specializing in plant anatomy.
