Bioingegneria

The purpose of the book is to bring together in one place the different facets of regenerative biology and medicine while providing the reader with an overview of the basic and clinically-oriented research that is being done. Not only does the content cover a plethora tissues and systems, it also includes information about the developmental plasticity of adult stem cells and the regeneration of appendages. As part of its balanced presentation, "Regenerative Biology and Medicine" does address the biological/bioethical issues and challenges involved in the new and exciting field of regenerative biology and medicine. The tissues covered include skin, hair, teeth, cornea, and central neural types. The systems presented are digestive, respiratory, urogenital, musculoskeletal, and cardiovascular. It includes amphibians as powerful research models. It also discusses appendage regeneration in amphibians and mammals.

This abridged version of the bestselling reference "Handbook of Stem Cells, Two-Volume Set" attempts to incorporate all the essential subject matter of the original two-volume edition in a single volume. The material has been reworked in an accessible format suitable for students and general readers interested in following the latest advances in stem cells, including full color presentation throughout. Although some extra language and chapters have been deleted, rigorous effort has been made to retain from the original two-volume set the material pertinent to the understanding of this exciting area of biology. The organization of the book remains largely unchanged, combining the prerequisites for a general understanding of adult and embryonic stem cells; the tools, methods, and experimental protocols needed to study and characterize stem cells and progenitor populations; as well as a presentation by the world's experts of what is currently known about each specific organ system. The key features include: full-color presentation throughout; each chapter begins with 3-5 defined glossary terms, and all of the terms are collected in a comprehensive list within the book; and, references have been eliminated - now there are about 10 bibliographic entries per chapter.

Viviamo nella era del DNA e tutto intorno a noi oggi è riconducibile a questa molecola: l'economia, il sapere, le nanotecnologie, le riflessioni filosofiche, la giurisprudenza, la medicina. Oggi con la conoscenza dettagliata della sequenza del genoma umano, tutti questi aspetti del nostro vivere, anche come ci percepiamo, sono legati in qualche modo alla molecola del DNA. Persino la rappresentazione artistica oggi attinge alle informazioni legate a questa molecola; anche l'architettura. È dunque imperativo conoscere le opportunità offerte oggi dagli studi sul DNA: cellule staminali, cibi OGM, farmacogenomica, biobanche, solo per citare alcuni degli aspetti di maggiore rilevanza.

"Molecular Diagnostics" covers current molecular biological techniques used to identify the underlying molecular defects in inherited disease. Although an increasing number of laboratories, both academic and private are moving in that direction, there are only a few books in the existing literature, and they deal only partly with diagnosis at the molecular level. Each chapter includes the principle and a brief description of the technique, followed by examples from the authors' own expertise. Contributors are well-known experts in their field, and derive from a variety of disciplines, to ensure breadth and depth of coverage. This book: examines widely used molecular biology techniques to screen for genetic defects causing inherited disorders; includes state-of-the-art techniques for the detection of the underlying genetic heterogeneity leading to inherited disorders; identification of genetically modified organisms (GMO's); forensic analysis and every-day issues in a diagnostic laboratory; and discusses ethics, genetic counselling and quality management.

This is a comprehensive survey of the current state-of-the-art in hematopoietic stem cell transplantation for malignant disease. The authors focus on the indications and results of transplantation for acute leukemia, chronic myelogenous leukemia, lymphoma, multiple myeloma, and breast cancer. Special attention is given to transplant-related complications, including the pathophysiology and clinical consequences of acute and chronic GVHD, delayed immune reconstitution leading to infectious complications, and organ damage to the lung and liver. Additional chapters address the sources of stem cells and the effects of graft manipulation used to eliminate residual contaminating tumor cells in autologous transplantation, or to reduce the number of T lymphocytes causing GVHD in allogenic transplantation.

Tratto dalle lezioni tenute nell'a.a. 2003-2004 al corso di Analisi dei segnali biomedici della laurea triennale in Ingegneria Biomedica a Pisa, uno dei principali obiettivi del libro è quello di introdurre gli studenti a concetti di base e a strumenti metodologici necessari per affrontare corsi avanzati di elaborazione di segnali e immagini biomediche. Nel libro sono frequenti i richiami a problematiche di bioingegneria, per dimostrare praticamente l'importanza degli argomenti trattati nel percorso dell'ingegnere biomedico. Il testo fornisce una trattazione matematica sufficientemente approfondita dell'analisi di segnali deterministici e aleatori, della risposta impulsiva e funzione di trasferimento di sistemi lineari, e include alcuni richiami di calcolo combinatorio e calcolo delle probabilità. Inoltre sono trattati alcuni aspetti dell'analisi statistica di dati, in particolare la statistica descrittiva e inferenziale e l'impiego della tecnica delle componenti principali per risolvere problemi di analisi multivariata di dati medici. Non mancano importanti momenti progettuali riguardanti le metodologie di analisi e sintesi di filtri numerici e di analisi statistica multivariata.

Ricerca scientifica, sperimentazione, biotecnologie umane, ambiente, ogm, scelte economiche, allocazione delle risorse: tematiche che pongono politica, diritto e società di fronte a scelte dall'esito non scientificamente ed eticamente certo. Diventa allora fondamentale conoscere i termini scientifici delle questioni e gli esiti delle sperimentazioni per operare su queste basi un sano confronto che rifugga da presunte sicurezze facili proibizionismi, lassismo o inerzie. Pietro Greco, giornalista scientifico e scrittore, lavora per l'agenzia Zadig Roma. È direttore del "Master in comunicazione della scienza" presso la Scuola Internazionale Superiore di Studi Avanzati di Trieste. Collabora con il quotidiano L'Unità, con Rocca e altre riviste.

This volume is a new edition of the most authoritative book on Prion Biology, first published in 1999 and edited by the Nobel Prize-winning founder of the field. This expanded edition has been completely updated, and includes chapters on therapeutics, and diagnostic methods and approaches.

Superantigen Protocols assembles experimental protocols that have proved useful for the study of superantigens. These techniques will allow researchers from various areas of cell biology, microbiology, immunology, biochemistry, and molecular biology to assess the physical characteristics and biological effects of well-known superantigens as well as of putative substances that might have superantigenic activities, and to explore therapies for superantig- induced effects. Microbial exotoxins have been studied for decades as virulence factors because of their pathogenic effects. The term "superantigen" was coined by Marrack and Kappler a decade ago for some of these molecules because of their potent T-cell stimulatory activities. In recent years, advances in mole- lar biology provide recombinant as well as natural superantigens in highly purified form for physical characterization. Superantigens are now used extensively as tools to study interactions between receptors on cells of the immune system as they bind to major histocompatibility complex class II m- ecules on antigen-presenting cells and V regions of T-cell receptors. The b- ? logical effects that result from these interactions are studied both in vitro and in vivo. The intent of this book is, therefore, to bring together up-to-date te- niques developed by experts in the field of biochemistry, immunology, and molecular biology for the study of superantigens. Superantigen Protocols begins with an overview of the field to provide background information on the various classes of superantigens and their str- ture.
