Oecd Guidelines For The Testing Of Chemicals Section 4 Test No 413 Subchronic Inhalation Toxicity 90 Day Study

This revised Test Guideline has been designed to fully characterize test article toxicity by the inhalation route for a subchronic duration (90 days), and to provide robust data for quantitative inhalation risk assessments. Groups of 10 male and 10 ...

This study relates to the analysis, via dermal application, of the health hazards of solid or liquid test substance. It may be carried out after initial information obtained by acute testing. This method is composed of the main test and the limit ...

The objective of these chronic toxicity studies is to characterize the profile of a substance in a mammalian species (primarily rodents) following prolonged and repeated exposure. The Test Guideline focuses on rodents and oral administration. Both ...

The objective of a long-term carcinogenicity study is to observe test animals for a major portion of their life span for the development of neoplastic lesions during or after exposure to various doses of a test substance by an appropriate route of ...

The objective of a combined chronic toxicity/carcinogenicity study is to identify carcinogenic and the majority of chronic effects, and to determine dose-response relationships following prolonged and repeated exposure. The rat is typically used for ...

Mycotoxins are increasingly attracting attention at thegovernmental, public and academic level worldwide, due to more frequent and serious contaminations of food and feedstuffs, which pose a serious threat to human health and animal production. This book reviews the latest research on mycotoxins that directly concern food safety, and especially focuses on detection technologies, risk assessment and control strategiescurrently being used in China. Gathering contributions from over 20 respected researchers, the book will benefit graduatestudents, researchers and management groups from various disciplines, including food science and technology, analytical chemistry, plant pathology, public health, etc.

This revised Test Guideline 412 (TG 412) has been designed to fully characterize test article toxicity by the inhalation route following repeated exposure for a limited period of time (28 days), and to provide data for quantitative inhalation risk ...

Nanotechnology has the potential to change every part of our lives. Today, nanotechnology-based products are used in many areas, and one of the most important areas is drug delivery. Nanoparticulate drug delivery systems not only provide controlled delivery of drugs and improved drug solubility but also improve drug efficiency and reduce side effects via targeting mechanisms. However, compared with conventional drug delivery systems, few nanoparticle-based products are on the market and almost all are nontargeted or only passively targeted systems. In addition, obtaining targeted nanoparticle systems is quite complex and requires several evaluation mechanisms. This book discusses the production, characterization, regulation, and currently marketed targeted nanoparticle systems in a broad framework. It provides an overview of targeted nanoparticles’ (i) in vitro characterization, such as particle size, stability, ligand density, and type; (ii) in vivo behavior for different targeting areas, such as tumor, brain, and vagina; and (iii) current advances in this field, including clinical trials and regulation processes.
