The cyanogenic glycosides, here defined as glycosidic derivatives of iX-hydroxynitriles, represent a rather limited class of natural products, which are widely distributed in the plant kingdom and, to a small ex- tent, even in animals. A characteristic feature of these glycosides is their ability to release hydrocyanic acid on treatment with dilute acids or appropriate enzymes. The term "cyanogenic" is used to designate this property, regardless of whether pure substances, plants, or animals, are serving as the source. In the latter cases the term "cyanophoric" is occasionally employed synonymously. Cyanogenesis in plants was probably first discovered by SCHRADER in 1803 (Io3) working with bitter almonds. In 1830, ROBIQUET and BOUTRON-CHARLARD (IOO) succeeded in isolating the parent glycoside, namely amygdalin. Over the years, a total of 18 cyanogenic glycosides have been isolated and characterized more or less completely (Table I, p. 76). It will be noted that the majority of these compounds has been isolated in the era of classical organic chemistry and that progress in .discovering new compounds, not to mention new structural types, has been surprisingly slow. It is worth remembering here that the mechanism *of cyanogenesis has been established only in the minority of known cyanogenic species. The cyanogenic glycosides have last been reviewed in 1958 by DILLE- MANN (36). Since then, no complete reviews in this field have appeared. It is the purpose of the present article to survey the more recent ad- vances and, hopefully, to stimulate continued interest in these interesting .compounds.

Eine grosse Anzahl heterocyclischer Naturstoffe leitet sich vom Ring- system des Piperidins (1) ab. Als Substituenten einfach oder mehrfach substituierter Piperidinbasen finden sich Methyl-, Carboxyl-, Hydroxyl- und Aminogruppen sowie aliphatische Seitenketten unterschiedlicher Lange. Die Substitution erfolgt bevorzugt an den C-Atomen 2, 3 und 6 sowie am Heteroatom. In zahlreichen Fallen ist der Piperidinring in a- oder ss-Stellung direkt oder uber eine C-Brucke mit einem weiteren Heterocyclus verbunden, z. B. einem Piperidin-, Piperidein-, Pyridin-, Indol-, Chinolizidin- oder Furanrest. Daruber hinaus kann der Piperidin- ring zum 2,6-Dioxopiperidin (Glutarimid) oxydiert oder zum Pipendein dehydriert sein. Wahrend Naturstoffe mit Pyridinstruktur im Tier- und Pflanzenreich weit verbreitet sind und einzelnen von ihnen wie NAD oder Pyridoxal- phosphat als Coenzymen des Primarstoffwechsels besondere Bedeutung zukommt, handelt es sich bei den naturlichen Piperidinverbindungen im allgemeinen um sekundare Pflanzenstoffe (vgl. I8, I9I). Dabei sind einige wie z. B. die Pipecolinsaure (7) sporadisch auf verschiedene Pflanzen- familien verteilt. Andere Piperidinbasen wie die Conium- oder Piper- Alkaloide weisen dagegen eine ausgesprochene Artspezifitat auf. Im Gegensatz zu den meisten Pyridinalkaloiden finden sich die Piperidin- basen oft mit strukturell andersartig gebauten Alkaloiden vom Chino- lizidin- oder Trepantyp vergesellschaftet, was in den meisten Fallen durch eine enge biogenetische Verwandtschaft bedingt sein durfte.

Praise for the Third Edition "This is one of the best books available. Its excellent organizational structure allows quick reference to specific models and its clear presentation ...solidifies the understanding of the concepts being presented." - IIE Transactions on Operations Engineering Thoroughly revised and expanded to reflect the latest developments in the field, Fundamentals of Queueing Theory , Fourth Edition continues to present the basic statistical principles that are necessary to analyze the probabilistic nature of queues. Rather than presenting a narrow focus on the subject, this update illustrates the wide-reaching, fundamental concepts in queueing theory and its applications to diverse areas such as computer science, engineering, business, and operations research. This update takes a numerical approach to understanding and making probable estimations relating to queues, with a comprehensive outline of simple and more advanced queueing models. Newly featured topics of the Fourth Edition include: Retrial queues Approximations for queueing networks Numerical inversion of transforms Determining the appropriate number of servers to balance quality and cost of service Each chapter provides a self-contained presentation of key concepts and formulae, allowing readers to work with each section independently, while a summary table at the end of the book outlines the types of queues that have been discussed and their results. In addition, two new appendices have been added, discussing transforms and generating functions as well as the fundamentals of differential and difference equations. New examples are now included along with problems that incorporate QtsPlus software, which is freely available via the book's related Web site. With its accessible style and wealth of real-world examples, Fundamentals of Queueing Theory , Fourth Edition is an ideal book for courses on queueing theory at the upper-undergraduate and graduate levels. It is also a valuable resource for researchers and practitioners who analyze congestion in the fields of telecommunications, transportation, aviation, and management science.

What Democrats Talk about When They Talk about God is a collection of essays on the religious communication of members of the Democratic Party, past and present-in office, while campaigning, and in their public and private writing. While many books on the market address issues at the intersection of church and state, none to date have focused exclusively on Democrats as important participants in the dialogue about religion and politics.

This edition of Otolaryngologic Clinics focuses on all aspects of robotic-assisted surgery in Otolaryngology including current, well-accepted techniques as well as emerging applications of the technology. Interest in TORS has increased dramatically as other applications of robotic surgery are explored including robotic-assisted approaches to the thyroid, anterior skull base, and neck. Each article in this edition of Oto Clinics highlights a specific application of robotic surgery in Otolaryngology and includes a detailed step-by-step approach with associated online videos. In depth discussion of indications, complications, and technical pearls accompany each article. TORS for Tonsil cancer; Base of tongue Cancer; Larynx cancer; Sleep apnea; Parapharyngeal spcae; and Benign lesions of the pharynx is presented along with Robotic approaches to anterior skull base and thyroid, Transaxillary robotic thyroidectomy; Transfacial robotic thyroidectomy; and Robotic approaches to the neck.

Der vorliegende fiinfte Band aus der Weiterbildungsreihe HNO-Almanach ist, wie schon der neue Titel zeigt, noch mehr als seine Vorganger auf die BedUrfnisse des niedergelassenen Facharztes ausgerichtet. Neben Themen aus der Otologie und Rhinologie werden auch drei allgemeine Beitrage vorgeste11t. Die topodiagnostische Audiometrie, bisher vielerorts noch ein Stiefkind der Praxis, erlangt zunehmende Bedeutung durch die haufig verlangten Beurteilungen Larmschwerhoriger, sie ist neuerdings auch fUr die Horge- ratverordnung zur Pflicht gemacht worden. Die allergischen Erkrankungen von Nase und Nasennebenhohlen sind eine therapeutische crux fUr den Oto-Rhinologen. Der entsprechende Beitrag soll zumindest Verstandnis fUr Zusammenhange wecken und einige Behandlungsmoglichkeiten auf- zeigen. - In der operativen Tatigkeit des HNO-Arztes werden die Ton- sillektomien, frillier Hauptkontingent an Eingriffen, immer seltener. Die radikalen Nebenhohlenoperationen scheinen durch ambulant mogliche konservativ-endoskopische Verfahren, wie ausfiihrlich beschrieben, ersetzt zu werden. Eine allgemeine Umorientierung bahnt sich an. Deshalb muf, sich der niedergelassene Kollege tiberlegen, ob er nicht sein operatives Rtistzeug voll ausnutzen und - neben rhinologischen und plastischen Ein- griffen - auch wieder Ohroperationen ausflihren will, sollen seine Betten nicht leer stehen. - Labordaten spielen in der HNO-Heilkunde eine unter- geordnete Rolle, auch ist dieses Gebiet wegen der Honorarkiirzungen neu- erdings unbeliebt. Trotzdem sollte der Ohrenarzt urn die Vorteile eines verhaltnismaflig leicht realisierbaren eigenen mittleren Labors wissen. Der Beitrag tiber die Antibiotikatherapie solI helfen, das fUr den jeweiligen Erkrankungsfall wirksamste Chemotherapeutikum zu finden, das nicht im- mer ein "Billigpraparat" sein kann (Pyocyaneusinfektion).

Viele Arzte hofften, daB mit der Reindarstellung des Morphins und der EinfUhrung des Athers und des Chloroforms im neunzehnten Jahrhundert, dem "Jahrhundert der Chirurgen," das Schmerzpro blem gel6st sei. Heute wissen wir, daB wir erst am Anfang der L6sung stehen und trotz wunderbarer Fortschritte in der Herstellung syn thetischer Analgetica, Lokalanaesthetica und Narkotica tausende von bisher unheilbaren Schmerzpatienten auch heute noch von Arzt zu Arzt und von Klinik zu Klinik wandern, ohne das ihnen wirkliche dauerhafte Hilfe zuteil wird. Nur wenn wir dieses qualvolle Leiden der Armsten der Armen in den Griff bekommen, wird das zwanzigste Jahrhundert als "Jahrhundert der Anaesthesisten" in die Geschichte der Medizin eingehen. Der Pionier der Schmerztherapie und Grunder der ersten Schmerz klinik der Welt, Professor JOHN BONICA von der University of Washing ton in Seattle, seine Schuler und seine Freunde haben in dem vor liegenden Band ihre Auffassungen und Erfahrungen bei der Behand lung chronisch schmerzkranker Patienten niedergelegt. Ich hoffe, daB dadurch der erste Schritt getan wird zur Grundung von Schmerz kliniken auch an deutschen UniversiHiten entsprechend dem Vorbild der Vereinigten Staaten, Japans, Skandinaviens und anderer Kultur lander.
