A new video resource for introductory training on the 3Rs
The NC3R published a new educational video on the 3Rs (replacement, refinement and replacement) on their web page. It is a great resource, you might want to check it out!

Example of how to perform randomization
The Lambeth Conventions (II): Guidelines for the study of animal and human ventricular and supraventricular arrhythmias
A convenient way to ensure adequate randomisation that allows for easy rejection plus replacement of excluded subjects is the procedure of randomisation to lines. This may be achieved by coding the test groups and assigning a subject to a group within a line, with the identity and order of each group varied from one line to the next.
