Available in PDF, EPUB and Kindle. Book excerpt: This book was not written for contemporary scientists with a major interest in cell biology. Rather, it was prepared for the serious and inquiring student who mayor may not have had an extensive background in the sciences but who is interested in exploring or reviewing in depth the current body of knowledge about cellular structure and function. We have tried to convey a sense of the expectant excitement that characterizes the modem-day cellular biologist and we regret any scientific jargon that may have crept into the text as a result of this effort. We have selected and assimilated experiments done by numerous scien tists and have used them to explain how cells work. In doing this, we have concentrated on animal cells because we know more about them. We have come to a deeper appreciation, while preparing this book, of the limitations in understanding the inner workings of the cell and have come to realize more than ever that we are, in these matters, still "looking through a glass darkly. " An explosively increasing body of knowledge about the cell and its organelles has become available through the diligent work of numerous biologists. Thus it is impractical to attempt to credit each of these scientists for all of their important contributions: The listed references are neither exhaustive nor are they necessarily the first report of a finding.

Book excerpt: 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 excerpt: The purpose of this volume is to provide a synopsis of present knowledge of the structure, organisation, and function of cellular organelles with an emphasis on the examination of important but unsolved problems, and the directions in which molecular and cell biology are moving. Though designed primarily to meet the needs of the first-year medical student, particularly in schools where the traditional curriculum has been partly or wholly replaced by a multi-disciplinary core curriculum, the mass of information made available here should prove useful to students of biochemistry, physiology, biology, bioengineering, dentistry, and nursing. It is not yet possible to give a complete account of the relations between the organelles of two compartments and of the mechanisms by which some degree of order is maintained in the cell as a whole. However, a new breed of scientists, known as molecular cell biologists, have already contributed in some measure to our understanding of several biological phenomena notably interorganelle communication. Take, for example, intracellular membrane transport: it can now be expressed in terms of the sorting, targeting, and transport of protein from the endoplasmic reticulum to another compartment. This volume contains the first ten chapters on the subject of organelles. The remaining four are in Volume 3, to which sections on organelle disorders and the extracellular matrix have been added.

Book excerpt: Apart from the short-range interactions mediated by diffusion, long-scale interactions are indispensable for giant plant cells including internodal cells of Characeae because the inefficiency of diffusion for millimeter- and centimeter-scale distances should be counterbalanced by other mechanisms to ensure the integrity of cell metabolism. In this collection, the authors begin by presenting one approach for studying the cyclosis-mediated transmission of regulatory signals along the characean internode by illuminating a cell part with a narrow light beam and to observe the changes of modulated chlorophyll fluorescence occurring in response to this photostimulus at a fixed distance on the downstream side of the light spot.Following this, the features and characters of various chloroplast genomes that could be retrieved solely from the analysis of triplet composition were studied. Two types of triplet dictionaries were developed: the former lists all the triplets (with overlapping), so that each nucleotide yields a start for a triplet, and the latter is the entity where triplets do not overlap but also have no gaps between them.The authors go on to describe the effects of cytoplasm on the expression of cytoplasmic male sterility and other agronomically valuable traits in the grain sorghum and sorghum × Sudan grass hybrids, as well as on the combining ability for these traits. It is hypothesized that the cytoplasm, being a buffer between the external environment and the nuclear genome, processes environmental signals and thus has a significant effect on the manifestation of nuclear-encoded traits.A nonlocal strain gradient beam model is developed including the both hardening-stiffness and softening-stiffness size effects in conjunction with the geometrical nonlinearity in the concluding study. Via the variational approach, the governing differential equations are constructed corresponding to each nonlinear mechanical behavior of the lipid micro/nano-tubule surrounded by the cytoplasm biomedium.

Available in PDF, EPUB and Kindle. Book excerpt: The compartmentation of genetic information is a fundamental feature of the eukaryotic cell. The metabolic capacity of a eukaryotic (plant) cell and the steps leading to it are overwhelmingly an endeavour of a joint genetic cooperation between nucleus/cytosol, plastids, and mitochondria. Alter ation of the genetic material in anyone of these compartments or exchange of organelles between species can seriously affect harmoniously balanced growth of an organism. Although the biological significance of this genetic design has been vividly evident since the discovery of non-Mendelian inheritance by Baur and Correns at the beginning of this century, and became indisputable in principle after Renner's work on interspecific nuclear/plastid hybrids (summarized in his classical article in 1934), studies on the genetics of organelles have long suffered from the lack of respectabil ity. Non-Mendelian inheritance was considered a research sideline~ifnot a freak~by most geneticists, which becomes evident when one consults common textbooks. For instance, these have usually impeccable accounts of photosynthetic and respiratory energy conversion in chloroplasts and mitochondria, of metabolism and global circulation of the biological key elements C, N, and S, as well as of the organization, maintenance, and function of nuclear genetic information. In contrast, the heredity and molecular biology of organelles are generally treated as an adjunct, and neither goes as far as to describe the impact of the integrated genetic system.

Book excerpt: Concepts of Biology is designed for the single-semester introduction to biology course for non-science majors, which for many students is their only college-level science course. As such, this course represents an important opportunity for students to develop the necessary knowledge, tools, and skills to make informed decisions as they continue with their lives. Rather than being mired down with facts and vocabulary, the typical non-science major student needs information presented in a way that is easy to read and understand. Even more importantly, the content should be meaningful. Students do much better when they understand why biology is relevant to their everyday lives. For these reasons, Concepts of Biology is grounded on an evolutionary basis and includes exciting features that highlight careers in the biological sciences and everyday applications of the concepts at hand.We also strive to show the interconnectedness of topics within this extremely broad discipline. In order to meet the needs of today's instructors and students, we maintain the overall organization and coverage found in most syllabi for this course. A strength of Concepts of Biology is that instructors can customize the book, adapting it to the approach that works best in their classroom. Concepts of Biology also includes an innovative art program that incorporates critical thinking and clicker questions to help students understand--and apply--key concepts.
