Antioxidants in Animal Tissue.

Oxidative stress, antioxidants, and animal function.

Reactive oxygen metabolites generated during normal metabolism and metabolism stimulated by xenobiotics can enter into reactions that, when uncontrolled, can impair performance of dairy cows. Direct effects include peroxidative changes in membranes and other cellular components. Indirectly, competitive consumption of reducing equivalents can interfere with important metabolic functions and dive...

European Animal Tissue Directive.

In less than nine months, manufacturers of medical devices containing certain types of tissues of animal origin will need to ensure that their products comply with newly mandated specifications. They should not wait until the last minute to begin this work. This article discusses the important issues that will need to be addressed to ensure effective compliance with the requirements.

Animal Tissue Techniques

Clearly, the possibility that Van Peenen's statements are correct exists, but no molecular geneticist would contend that these assertions have been established, in any but a very few cases, which appear at present to be atypical. The educated lavman, for whom this book is intended, will find the author's leaps from the level of the quoted material into sophisticated physical chemistry and back ...

SYMPOSIA AND ORAL PRESENTATIONS Animal Health: Probiotics, Performance and Antioxidants

Thiamine deficiency causes a decrease in transketolase activity and an increase in thiamine pyrophosphate (TPP) effect on the erythrocytes. The objective of this experiment was to determine if ruminal acidosis alters erythrocytic transketolase enzyme activity as an indicator of thiamine level in feedlot cattle. A total of 65 feedlot cattle (1–2 years old) were fed either high concentrate diet (...
