The cocaine- and amphetamine-regulated transcript (CART) is a known factor in appetite and feeding behaviour.
However, the secret of success of this book may probably be found in Professor Kiernan’s words, in the book Preface: singles over 50 dating site The purpose of this book is to teach the chemical, physical and biological principles of fixation, staining and histochemistry.
I urge the reader always to determine the reason for every step in a method before doing it [….].
This is the reason: an intelligent approach, with attention to the rationale of each method!The final Chapter 20 collects a miscellanea of useful recipes for buffers and physiological solutions, and a list of mammalian tissues to be used as positive controls for histochemical and enzyme histochemical reactions.A table of contents precedes the main text of each chapter, and the volume ends with a very rich bibliography (about fifty pages), which allows the reader to go deeper into the theory and application of specific methods, referring to the articles where these have originally been proposed.After 3 and 42 days following the procedure, statistically significantly higher numbers of CART-positive cells were identified in comparison with the control animals.The differences between the hypertensive rats and the control animals concerned not only the number density of CART-immunoreactive cells but also their localization.Chapters 7 to 12 deal with the methods for staining cells in suspension, and with the histochemical techniques for identifying nucleic acids, different functional groups of proteins, carbohydrates and lipids.Chapter 13 concerns the methods for detecting inorganic ions or pigments, such as melanin, lipofoscins or bile pigments.CART was detected in the endocrine cells, especially numerous in the submucosa and muscularis layers, with a few found in the transitional epithelium and only occasionally in serosa.Hypertension significantly increased the number of CART-positive cells in the rat UBs.Enzyme histochemistry is the subject of chapters 14 to 16, where special emphasis on hydrolases and oxidoreductases is given.In Chapter 17, the methods for localizing soluble organic compounds of low molecular weight (especially amines) in bright-filed or fluorescence microscopy are described, while Chapter 18 illustrates staining methods which produce deposits of metals or dark final reaction products: these are used to demonstrate the presence of chemical compounds which cannot be stained with come incontrare solo ragazze su chatroulette conventional dyes, and may be applied for a variety of purposes, from general histology, to microbiology or neurobiology, or to induce amplification of the final reaction products of histochemical or immunohistochemical reactions.
