A literature survey funded by the Foundation Animalfree Research was performed to obtain an overview on animal experiments in nanotechnology. Scientific articles from Germany, France, the United Kingdom, Italy, the Netherlands and Switzerland published between 2004 and 2007 were collected. A total of 164 articles was retrieved covering in vivo nanotechnological research. The majority of animal ...

Experiments on human and on animal excised specimens as well as in vivo animal preparations are so far the most realistic approaches to simulate the in vivo process of human phonation. These experiments do not have the disadvantage of limited space within the neck and enable studies of the actual organ necessary for phonation, i.e., the larynx. The studies additionally allow the analysis of flo...

Introduction levels, and one of their strengths is that they permit a more global, integrated view of the National (1) and European (2) legislation human brain. requires the replacement, reduction and refine­ However, replacing animal experiments ment of animal experiments wherever feasible, requires more than technology: it also needs placing a responsibility on scientists and others a commitm...

To advance our understanding of biological processes we often plan our experiments based on published data. This can be confusing though, as data from experiments performed in a laboratory environment are sometimes different from, or completely opposite to, findings from similar experiments performed in the "real world". In this mini-review, we discuss instances where results from laboratory ex...

Amphibian experiments on nerve-muscle preparation and heart are essential as per first year MBBS practical syllabus, for learning basic concepts in Physiology. Need was felt to design and develop computer based simulation software as an alternative to animal use, due to growing concern and stringent laws imposed by animal ethical bodies. Computer algorithms were developed for 13 amphibian exper...

The basic patterns of inheritance of learning ability in animals have been delineated. Summaries of strain differences in learning rate, responses to selective breeding for learning, heritabilities of learning phenotypes, and heterosis and overdominance are presented. In addition, the patterns of inheritance are shown to vary with the early environment. The causes of genetic differences have re...

Atherosclerotic heart diseases are universal problems in modern society. Oxidative damage to lipids is a primary cause of atherosclerosis. There are many choices for treatment, but no definite recommendations to prevent the occurrence of the disease. There is a relationship between atherosclerotic risk factors and increased vascular production of reactive oxygen species (ROS). Oxidized low-dens...
