Mycotoxin Protocols by Mary W. Trucksess,Albert E. Pohland Pdf

Mycotoxins produced by molds are common contaminants of many important crops, including wheat, corn, rice, and peanuts. Some mycotoxins are found in fruits and vegetables. These contaminants have a broad range of toxic effects, including carcinogenicity, neurotoxicity, and reproductive and developmental toxicity. The occurrence of mycotoxins in foods is an unavoidable worldwide problem. About 80 countries have imposed regulatory limits to minimize human and animal exposure to mycotoxins. Regulatory limits, including international standards, have tremendous economic impact and must be developed using science-based risk assessments. The purpose of Mycotoxin Protocols is to provide the scientific and technological basis for analytical methods for use in obtaining the exposure data needed for risk assessments. Mycotoxin Protocols is divided into four sections, which are interc- nected. The first section: Chapters 1–5 describe the general techniques for mycotoxin analysis with emphasis on the importance of method validation based on statistical parameters; sampling procedures for collecting a sample as representative as possible of a bulk lot; the isolation of mycotoxins for use as analytical standards or for toxicological studies; the evaluation of purity and preparation of standards; and the detection and identification of impu- ties in isolated mycotoxins. Sections 2–4: Chapters 6–19 describe the most current chromatographic and immunochemical methods for studies on the major mycotoxins.

Mycotoxins and Food Safety by Jonathan W. DeVries,Mary W. Trucksess,Lauren S. Jackson Pdf

Mycotoxins, from the Greek "mukes" referring to fungi or slime molds and toxin from the Latin "toxicum" referencing a poison for arrows, have earned their reputation for being potentially deleterious to the health and well being of a consuming organism, whether it be animal or human. Unfortunately, mycotoxins are a ubiquitous factor in the natural life cycle of food producing plants. As such, control of the potential impact of mycotoxins on food safety relies heavily upon accurate analysis and surveys followed by commodity segregation and restricted use or decontamination through processing. The purpose of this book is to provide the most comprehensive and current information on the topic of mycotoxins and assuring food safety. Chapters represented in the book reflect such diverse topics ranging from occurrence and impact, analysis, reduction through processing and plant breeding, toxicology and safety assessments to regulatory perspectives. Authors represent a range of international perspectives.

Mycotoxins in Food and Beverages by Didier Montet,Catherine Brabet,Ramesh C. Ray,Sabine Galindo Pdf

Mycotoxins are secondary metabolites produced by fungi in a wide range of foods (cereals, peanut, tree nuts, dried fruits, coffee, cocoa, grapes, spices...) both in the field and after harvest, particularly during storage. They can also be found in processed foods of plant origin, or by transfer, in food products of animal (milk, eggs, meat and offal). Mycotoxins are of major concern since they can cause acute or chronic intoxications in both humans and animals which are sometimes fatal. Many countries, particularly in Europe, have set maximum acceptable levels for mycotoxins in food and feed. The book reviews the latest literature and innovations on important aspects of mycotoxins, e.g. mycotoxin producing fungi and the related ecosystems, mycotoxin occurrence, toxicity, analysis and management. Quantitative estimations of impacts of climate change on mycotoxin occurrence have been made recently, using predictive modelling. There is also a growing interest in the occurrence and toxicity of multiple mycotoxins in food and feed, including emerging or modified forms of mycotoxins. Innovative tools were also developed to detect and quantify toxinogenic fungi and their toxins. In order to reduce the use of chemicals that are harmful to the environment and health of consumers, alternative methods of prevention and decontamination of mycotoxins were tested in pre- and post-harvest, using microorganisms, natural substances or radiation treatments.

Genomics Protocols by Michael P. Starkey,Ramnath Elaswarapu Pdf

We must unashamedly admit that a large part of the motivation for editing Genomics Protocols was selfish. The possibility of assembling in a single volume a unique and comprehensive collection of complete protocols, relevant to our work and the work of our colleagues, was too good an opportunity to miss. We are pleased to report, however, that the outcome is something of use not only to those who are experienced practitioners in the genomics field, but is also valuable to the larger community of researchers who have recognized the potential of genomics research and may themselves be beginning to explore the technologies involved. Some of the techniques described in Genomics Protocols are clearly not restricted to the genomics field; indeed, a prerequisite for many procedures in this discipline is that they require an extremely high throughput, beyond the scope of the average investigator. However, what we have endeavored here to achieve is both to compile a collection of procedures concerned with geno- scale investigations and to incorporate the key components of “bottom-up” and “top-down” approaches to gene finding. The technologies described extend from those traditionally recognized as coming under the genomics umbrella, touch on proteomics (the study of the expressed protein complement of the genome), through to early therapeutic approaches utilizing the potential of genome programs via gene therapy (Chapters 27–30).

Gene Knockout Protocols by Martin J. Tymms,Ismail Kola Pdf

As the major task of sequencing the human genome is near completion and full complement of human genes are catalogued, attention will be focused on the ultimate goal: to understand the normal biological functions of these genes, and how alterations lead to disease states. In this task there is a severe limitation in working with human material, but the mouse has been adopted as the favored animal model because of the available genetic resources and the highly conserved gene conservation linkage organization. In just of ten years since the first gene-targeting experiments were p- formed in embryonic stem (ES) cells and mutations transmitted through the mouse germline, more than a thousand mouse strains have been created. These achievements have been made possible by pioneering work that showed that ES cells derived from preimplantation mouse embryos could be cultured for prolonged periods without differentiation in culture, and that homologous rec- bination between targeting constructs and endogenous DNA occurred at a f- quency sufficient for recombinants to be isolated. In the next few years the mouse genome will be systematically altered, and the techniques for achi- ing manipulations are constantly being streamlined and improved.

Cytoskeleton Methods and Protocols by Ray H. Gavin Pdf

Over the past two decades experimental studies have solidified the int- pretation of the cytoskeleton as a highly dynamic network of microtubules, actin microfilaments, intermediate filaments, and myosin filaments. Rather than a network of disparate fibers, these polymers are often interconnected and display synergy, which is the combined action of two or more cytoskeletal polymers to achieve a specific cellular structure or function. Cross-commu- cation among cytoskeletal polymers is thought to be achieved through cytoskeletal polymer accessory proteins and molecular motors that bind two or more cytoskeletal polymers. Development of the modern concept of the cytoskeleton is a direct o- growth of advances in experimental tools and reagents that are available to cell and molecular biologists. Technological advances and refinements in cell imaging have made it possible to selectively image a single cytoskeletal po- mer and monitor its dynamics through the use of fluorescence probes in vitro and in vivo. Two decades ago, cytoskeletal research was limited to a few perturbation reagents that included colchicine and cytochalasin. Today, the perturbation arsenal has expanded to a highly selective group of reagents that includes Taxol, nocodazole, benomyl, latrunculin, jasplakinolide, and such endogenous proteins as gelsolin. These reagents enable the investigator to selectively perturb or destroy a cytoskeletal polymer while leaving other cytoskeletal polymers intact. Site-specific monoclonal antibodies that target a specific cytoskeletal polymer have proven to be highly selective affinity tools for cytoskeletal research.

Sampling Procedures to Detect Mycotoxins in Agricultural Commodities by Thomas B. Whitaker,Andrew B. Slate,M. Bruno Doko,Britt M. Maestroni,Andrew Cannavan Pdf

Adherence to regulatory limits for mycotoxins in agricultural commodities is important to safeguard consumers and to permit trade in affected commodities across international borders. Reliable estimates of mycotoxin concentrations are required to implement regulatory decisions on the suitability of lots of produce for consumption or trade. Effective schemes to test for mycotoxins depend not only upon sound analytical methods, but also on well designed and implemented sampling plans. This manual provides information to food analysts and regulatory officials on effective sampling plans to detect mycotoxins in food. The concepts of uncertainty and variability in mycotoxin test procedures are discussed as well as the importance of ensuring that samples are representative of the lot being sampled, and the consequences of a poorly designed sampling plan on the reliability of the measured levels of mycotoxins, possibly resulting in legal disputes and barriers to trade.

Extracellular Matrix Protocols by Charles Streuli,Michael Grant Pdf

It is now widely accepted that much of the dynamic function of cells and tissues is regulated from outside the cell by the extracellular matrix. In ad- tion to its conventional role in providing a scaffold for building tissues, the extracellular matrix acts as a directional highway for cellular movement and provides instructional information for promoting survival, proliferation, and differentiation. Indeed, the extracellular matrix is beginning to take a starring role in the choreography of cell and tissue function. The diverse roles of the extracellular matrix are reflected in its highly complicated structure, consisting of an ever increasing number of components. Yet the mechanisms of extracellular matrix assembly and how they influences cell behavior are only just beginning to be understood. In order to solve these problems new methodologies are, of necessity, being developed. Many of these technologies are highly sophisticated and are currently available only in a ha- ful of laboratories. However, we believe that they can readily be transported and established by other researchers. Thus, the purpose of Extracellular Matrix Protocols is to present some of these complicated techniques in a style that is relatively easy to reproduce.
