I ragni (Araneae Clerck, 1757) sono un ordine di Aracnidi, suddiviso in 120 famiglie che comprendono ben 48.349 specie. Sono artropodi terrestri provvisti di cheliceri e hanno il corpo suddiviso in due segmenti, cefalotorace e opistosoma, e otto zampe. I due segmenti sono congiunti da un piccolo pedicello di forma cilindrica. Come in tutti gli Artropodi, il celoma (cavità del mesoderma per il trasporto dei fluidi), pur essendo molto piccolo, consente il passaggio dell'emolinfa che ossigena e nutre i tessuti e rimuove i prodotti di scarto. L'intestino è così stretto che i ragni non possono mangiare alcun grumo di materiale solido, per quanto piccolo, e sono costretti a rendere liquido il loro cibo con vari enzimi digestivi e macinarlo finemente con l'apparato masticatorio. Ad eccezione del sottordine più primitivo, quello dei Mesothelae, i ragni hanno il sistema nervoso più centralizzato fra tutti gli Artropodi e, come questi, hanno i gangli cefalici fusi in una sola massa all'interno del cefalotorace. Diversamente dalla maggior parte degli artropodi, i ragni non hanno muscoli estensori nel loro corpo; i movimenti delle zampe e del corpo sono ottenuti attraverso variazioni di pressione del loro sistema idraulico. Nella parte terminale dell'addome sono presenti le filiere che estrudono la seta, usata per avvolgere le prede e costruire le ragnatele. La seta secreta dai ragni può essere considerata superiore a qualsiasi materiale sintetico finora elaborato per leggerezza, tenacia ed elasticità. I mini-ebook di Passerino Editore sono guide agili, essenziali e complete, per orientarsi nella storia del mondo. A cura di Antonio Ferraiuolo.

Nitric oxide (NO) has been discovered to play a fundamental role in a number of biological phenomena. This book describes various aspects of nitric oxide biology, physiology and pharmacology. It is divided into three sections. The first part deals with the basic chemistry and enzymology of NO, thus laying a molecular basis for what follows. The middle part surveys the physiological roles of NO under normal conditions. The concluding part explores the relevance of NO to disease, both as a pathogenic factor and a therapeutic target. The book thus provides detailed information on NO biology to the reader unfamiliar with the field and represents a reference work for scientists working in an NO-related field of biomedical research. Each chapter, written by experts in their fields, gives a broad introduction followed by a comprehensive review of the current knowledge and a detailed reference list.
