The main argument of this book is that cell signalling via nerves, hormones, local mediators and growth factors are not distinct phenomena, but branches of one general mechanism and should therefore be studied in an integrated manner. This volume is designed to act as a bridge between general texts and is aimed at biologists coming to the topic from a variety of backgrounds. The first two chapters introduce the general concepts of intracellular signalling and also cover the topic of direct cell-to-cell communication by cytoplasmic bridges (gap junctions). The remaining chapters cover the first and second messengers, starting with their structure, synthesis and release, progressing to the target cell and then working from the membrane inwards towards the nucleus. There is also a section on the mechanism of nervous conduction and the regulation of the ionic balace of cells. The final chapters discuss the regulation of cell growth and division and the special case of messengers acting via nuclear receptors.

"In the age of fake news, understanding who we trust and why is essential in explaining everything from leadership to power to our daily relationships." -Sinan Aral We live in a world where proven facts and verifiable data are freely and widely available. Why, then, are self-confident ignoramuses so often believed over thoughtful experts? And why do seemingly irrelevant details such as a person's appearance or financial status influence whether or not we trust what they are saying, regardless of their wisdom or foolishness? Stephen Martin and Joseph Marks compellingly explain how in our uncertain and ambiguous world, the messenger is increasingly the message. We frequently fail, they argue, to separate the idea being communicated from the person conveying it, explaining why the status or connectedness of the messenger has become more important than the message itself. Messengers influence business, politics, local communities, and our broader society. And Martin and Marks reveal the forces behind the most infuriating phenomena of our modern era, such as belief in fake news and how presidents can hawk misinformation and flagrant lies yet remain

During my many searches for knowledge and information, I have not discovered anything anywhere to contradict my findings in respect to the fact that ignorance, and all of its sources, are the main culprits for the propagation of ignorance, without which, the world would be a far better place. Imagine having at your disposal, the ability to correct many of the wrongs within society. This actually is the case if you are capable of recognising such facts. I regret deeply the fact that it is necessary to omit many pieces of information.

Scientists in lipid biochemistry research have increasingly recognized the role of lipids as signaling molecules, aside from their importance in forming cellular membranes and storing energy. This book provides the latest findings on a wide variety of complex lipids in cells that function either as intracellular or intercellular messengers. International investigators present current data on the most extensively studied examples of both intracellular and intercellular messengers generated from lipids, and describe their basic mechanisms, which also utilize receptors in the G-protein-coupled family. The in-depth discussions address such topics as lipid signaling for protein kinase C activation, phosphatidic acid and lyso-phosphatidic acid, ceramide as a messenger, bioactive properties of Sphingosine and structurally related compounds, platelet-activating factor and PAF-like mimetics, and prostaglandins and related compounds. Lipid Second Messengers is an up-to-date reference on developments in the expanding field of lipid-derived signals and will be of interest to biochemists, physiologists, pharmacologists, geneticists, and biologists.

This important new reference work offers an outstanding collection of articles devoted to the discussion of "intracellular messengers". Extracellular stimuli ("first messengers") bind to receptors on the plasma membrane of cells to trigger changes in the concentration of intracellular messengers ("second messengers") which leads, in turn, to changes in cellular activity. However, the intracellular activities of so called "third messengers" may also be involved complicating the concept of a rigid sequence of events between receptor and response. The preference for the term "intracellular messengers", and, hence, the title of this volume, recognizes that a complex web of interactions between intercellular messengers determines the concentrations and ultimate effects of each.

This book provides a scientific explanation of drug abuse and addiction for the general public. It clarifies the meaning of concepts such as intoxication, physical dependence, and addiction, and describes the changes in the brain that underlie these states. Indeed, this volume is unique because it presents a comprehensive picture of what actually happens to people and their brains when they chronically self-administer opiates, stimulants or alcohol. Complex mechanisms of drug action in the brain are made simple and comprehensible to the layman through use of informative analogies and salient graphics. Accounts of the effects of drug use and abuse on normal people create meaningful, easy-to-relate-to examples from everyday life.
