ECVAM's Activities on Biologicals
Alternatives to Laboratory Animals, 2002This paper summarises key activities initiated and the progress achieved between April 1993 and June 2002 in implementing the Three Rs in one of ECVAM's priority areas — the production and quality control of biologicals. These have included: organising nine key workshops; financially supporting and/or participating in a number of prevalidation and/or ...

Biologically active quinazolones
1994Quinazolinones form a large group among the pharmacologically active chemical moieties and are generally of little toxicity without serious side effects to the human body. Quinazolinones are versatile nitrogen heterocyclic compounds, displaying a broad spectrum of biological and pharmacological activities in animal as well as in human systems.

Biological activity of sterigmatocystin
Mycopathologia et Mycologia Applicata, 1968The biological activity of sterigmatocystin towards mice, ducklings, and some microorganisms was determined. The LD50 of sterigmatocystin for mice was in excess of 800 mg/kg. Aflatoxin B1 was 125 times more toxic in the ducklings tests than was sterigmatocystin.

1996
The addition of organic manure not only maintains but even improves soil fertility and, from earliest times, humus has been recognized as one of the major natural resources for agricultural purpose. In the absence of animal dung the value of green manure was recognized by the ancient Chinese (Jiao, 1983), while the Romans systematically used animal ...

The Biological Activity of Retinotaurine
The Journal of Nutrition, 1982The ability of the biliary metabolite retinotaurine to reverse the cornification of vaginal epithelial cells induced by vitamin A deficiency was assessed using a vaginal smear assay. Retinotaurine activity was examined following the intravaginal administration of 10(-12) mol to 10(-8) mol of this compound per vagina.

Biological Activities of Carrageenan
2014Red seaweeds are popular and economically important worldwide and also well known for their medicinal effects due to the presence of phycocolloids. Carrageenans, the major phycocolloid group of red algae, have been extensively investigated for their vast array of bioactivities such as anticoagulant, antiviral, cholesterol-lowering effects ...
