Tachykinins by Peter Holzer
More than 70 years have elapsed since U. S. von Euler and I. H. Gaddum dis- covered an unidentified depressor substance in the brain and gut. The effects of the powdery extracts were marked as 'P' on the kymograph tracings, and the nondescript name of 'substance P' still carries the breath of this adventurous period. In the 1960s, substance P returned in another disguise, staging as a hypothalamic peptide that causes copious salivary secretion (see chapter by F. Lembeck and I. Donnerer). This time, though, the mysterious substance was tracked down by S. E. Leeman and her collaborators as an undecapeptide, after it had eluded its identification for some 40 years. Substance P turned out to be the mammalian counterpart of a family of peptides which had been extracted from amphibian and nonvertebrate species and which had been given the name 'tachykinins' by V. Erspamer. Soon novel members of this peptide family were discovered, and in mammals substance P was joined by neurokinin A and neu- rokinin B. The presence of tachykinins in frog skin as well as in venoms and toxins of microbes and arachnids raises the possibility that these peptides re- present an old system of biological weapons that have been transformed to a particular messenger system in mammals.| ISBN 13 | 9783540206903 |

"I was paying $11.99/month for Kindle Unlimited but realized I was renting books, not owning them. Bought this PDF and it's mine forever. Never going back to Kindle."
"Switched from Kindle to these PDFs. Same book, but I actually OWN it now. No monthly fees, no app required. Worth every penny."
"Kindle Unlimited kept raising prices. This is a one-time purchase and the file is permanently on my iPad. Best decision I've made for my reading habit."
"I compared Kindle vs this store. Kindle is cheaper monthly but you don't own anything. Here I paid once and the PDF is mine for life. Highly recommend."
"Left Kindle behind after they removed a book I was reading mid-series. With this PDF, nobody can take it away from me. True ownership feels good."
"Was skeptical about paying $18.95 when Kindle shows $3.99, but then I did the math โ Kindle Unlimited is $143/year! This is way better value long term."
"Love that I can read this on any device without installing the Kindle app. The PDF works on my laptop, phone, and tablet seamlessly. So much freedom."
"My Kindle subscription was getting expensive. Switched to buying PDFs here and I'm saving money while actually building a permanent digital library I control."
