Book Description
The present Key Event based Test Guideline (TG) addresses the human health hazard endpoint skin sensitisation, following exposure to a test chemical. Skin sensitisation refers to an allergic response following skin contact with the tested chemical, as defined by the United Nations Globally Harmonized System of Classification and Labelling of Chemicals (UN GHS). This TG is proposed to address the activation of dendritic cells, which is one Key Event on the Adverse Outcome Pathway (AOP) for Skin Sensitisation. It provides four in vitro test methods addressing the same Key Event on the AOP: (i) the human cell Line Activation Test or h-CLAT method, (ii) the U937 Cell Line Activation Test or U-SENS, (iii) the Interleukin-8 Reporter Gene Assay or IL-8 Luc assay and (iv) the Genomic Allergen Rapid Detection for assessment of skin sensitisers (GARDTMskin). All of them are used for supporting the discrimination between skin sensitisers and non-sensitisers in accordance with the UN GHS. The test methods described in this TG either quantify the change in the expression of cell surface marker(s) CD54 and CD86, the cytokine IL-8, or a series of genes (genomic biomarker signature) that are associated with the process of activation of monocytes and DC following exposure to sensitisers.

Book Description
Human Organs-on-Chip: Novel Organ-on-a-Chip Techniques in Medicine paves the way for novel approaches that push forward in-vitro and in-vivo studies and fills a gap between laboratory and clinical use. These experienced authors share the knowledge they've developed with over a decade of experience and research with organ-on-chips and multi-organ-on-chips. This book collects all of the developments in the field and sheds new light on possibilities to develop human on-chip measurement methods with the utilization of currently available measurement techniques including both invasive and non-invasive tests. Human Organs-on-Chip: Novel Organ-on-a-Chip Techniques in Medicine serves as a starting point for young researchers who are beginning their scientific journeys. - Provides an overview of the progress suborgan-on-chips development has made in recent years - Introduces the fundamentals needed to understand lab-on-chip ideas with references and in-depth explanations - Presents commercial achievements obtained and future perspectives

Book Description
Practical Handbook on the 3Rs in the Context of the Directive 2010/63/EU provides updated information on the EU Directive 2010/63/EU, which is the European Union legislation that protects animals being used in research. EU Directive 2010/63/EU is the European Union (EU) legislation 'on the protection of animals used for scientific purposes' and is one of the most stringent ethical and welfare standards worldwide. - Closes a gap in scientific literature by addressing the need for clear guidance in walking through the multifaced universe of 3Rs - Offers a useful starting point for readers and scientist who approach the 3Rs for the first-time - Gives insights into the harmonization of the animal research legislation across countries

Book Description
This book provides latest findings in organotypic models in drug development and provides the scientific resonance needed in an emerging field of research in disciplines, such as molecular medicine, physiology, and pathophysiology. Today the research on human-based test systems has gained major interest and funding in the EU and the US has increased over the last years. Moreover, so-called 3R (reduce, replace, refine animal experiments) centres have been established worldwide.

Book Description
This Test Guideline describes in vitro assays, which use Androgen Receptor TransActivation (ARTA) to detect Androgen Receptor Agonists and Antagonists. The ARTA assay methods are mechanistically and functionally similar test methods that provide information on the transcription and translation of a reporter gene following the binding of a chemical to the androgen receptor and subsequent transactivation.

Book Description
The book about Non-bacterial toxins will cover those toxins that affect food safety and are produced by fungi (mycotoxins), cyanobacteria (cyanotoxins) and marine microalgae (phycotoxins). These three group of toxins affect food safety and drinking water quality at a global scale, and they pose three main challenges for scientists: 1) Climate change is causing a slow but steady change on the chemical profile of each of these groups, causing intoxications in areas that are geographically new to the intoxications map. For this reason, emerging toxins are a new topic that requires an important reallocation of resources to understand the new toxins trends, their toxicology, their analytical control and how to deal with them from a regulatory standpoint. 2) Toxicological science needs to be updated to determine the impact of the toxins in all kind of vectors (more and more are being discovered) and how they disseminate on the food chain. Also, the mode of action of many of this toxins is not understood or even known, and this affects also to the impact of the coexistence of several toxins in the same matrix. 3) Detection and regulation, as this requires the use of advance technology (mass spectrometry, biosensors, multitask screening etc) that is in many cases underdevelopped or not available, especially for many of the new toxins. Climate change, toxicology and detection affect so many areas of science that this book will try to keep the readers updated about the current state of the art.

Book Description
The Vitrigel-Eye Irritancy Test (EIT) method is an in vitro test method that allows the identification of test chemicals not requiring classification and labelling for eye irritation or serious eye damage. This test measures the eye irritation potential of a test chemical based on its ability to induce damage to the barrier function of the human corneal epithelium (hCE) models used in the Vitrigel-EIT method. It is known that chemicals that are irritating to the eye first destroy tear film and epithelial barrier function of the eye, subsequently induce epithelial cell death, and finally produce stromal degeneration and endothelial cell death, resulting in corneal opacity. Therefore, the change of the epithelial barrier function is a relevant endpoint for detecting eye irritation. In the Vitrigel Eye Irritancy test method , time-dependent changes in the Transepithelial Electrical Resistance (TEER) values are indicative of damage to the barrier function of the corneal epithelium following exposure to a test chemical; this situation is similar to the observed damage of the rabbit cornea following exposure to a test chemical, which is an important mode of action leading to damage of the corneal epithelium and eye irritation. The Vitrigel-Eye Irritancy Test (EIT) method can be used within the limited applicability domain of test chemicals having pH > 5.0 (based on 2.5% weight/volume (w/v) preparation).
