Experimental Design and Analysis of Data from Animal Experiments
The Center for Education and Lifelong Learning of the Aristotle University of Thessaloniki welcomes you to the, “Experimental Design and Analysis of Data from Animal Experiments” seminar, a 21,25 -hour f2f course which will take place at the “Professor V. Katsougiannopoulos” Room at the Laboratory of Hygiene, Social and Preventive Medicine and Medical Statistics, School of Medicine, Faculty of Health Sciences, Aristotle University of Thessaloniki, Thessaloniki, Greece.
The Director of the Programme is Dr. Anastasia Tsingotjidou, DVM, PhD, Associate Professor at the Laboratory of Anatomy, Histology and Embryology, School of Veterinary Medicine, Faculty of Health Sciences, Aristotle University of Thessaloniki, Thessaloniki, Greece with longstanding experience in experimental protocols using animal models.
Start Date: 13/12/2022
End of the course: 15/12/2022
Duration: 21,25 educational hours
Applications are submitted online here from 12/9/2022 to 1/12/2022
The use of animals in research is regulated by the principle of 3Rs (= Replacement, Reduction, Refinement), according to which in every research experiment that uses animals, replacement (= there is no other way than the use of animals to achieve the purpose of the study), reduction (= all measures have been taken to use as small a number of animals as possible for the correct outcome of the research problem), and refinement (= that all efforts have been made for the welfare of the animals used in the research) must be considered. According to the above, the aim of the program is to train everyone involved in animal experimentation in the proper way of experimental design and subsequent data analysis. Knowing the necessary number of animals in research is the only way that the use of animals is done correctly with the scientifically sound result.
The mandatory fields in the European Legislation on animals used for research purposes are listed at the official EU website: https://ec.europa.eu/environment/chemicals/lab_animals/index_en.htm. In that respect, every researcher needs to know, before writing a research protocol, basic principles for its design, as well as the ways of correct data analysis, which are two interconnected conditions. There are several websites on the internet that refer to this process: https://eda.nc3rs.org.uk/experimental-design, as well as guidelines: https://journals.sagepub.com/doi/full/10.1177/ 0023677217724823, which should be followed for a proper experimentation. All these online aids cannot replace the f2f teaching of the subject, which is based on multiple questions with answers from the participants. For this reason, the seminar comes to fill a gap in the Greek scientific community. The lecturers are from the field of medical sciences or have special knowledge of statistical processing.
Upon completion of the course, participants will learn:
1. design for research reproducibility2. basic principles of animal experimentation3. basic principles of quantitative comparison4. the basic mistakes in experimental design5. practices for quantitative comparison6. defining the 3Rs in experimental design7. the 3Rs in the experimental program8. the size of the experimental unit9. the statistical tools for quantitative comparison
Participant selection & Requirements
The seminar is aimed at those who intend to use animals in their research, as PhD candidates, postgraduate students, and postdoctoral researchers. They may belong to the health sciences: doctors, veterinarians, dentists, and pharmacists, as well as to the biological sciences, or from the field of psychology and engineering, who need animal experiments for their research. In addition, it also concerns scientists who have already used animals, who would be well informed about the new data on experimental design and data analysis.
A laptop will be necessary to participate in the course, in order to run the statistics software, along with a personal email account. The free software InVivoStat wil be used for exemplification of data analysis, and should be downloaded from this page. Examples on how to perform the analyses with SPSS will also be provided, for those using this software.
Participants will be selected based on their CV and their relationship to experimental design using animals. In the event that more people are interested in participating in the seminar, they will be selected by a priority order.
The seminar, a 21,25 -hour f2f course which will take place at the “Professor V. Katsougiannopoulos” Room at the Laboratory of Hygiene, Social and Preventive Medicine and Medical Statistics, School of Medicine, Faculty of Health Sciences, Aristotle University of Thessaloniki, Thessaloniki, Greece.
At the end of each session the participants will form 3-4 persons working groups and they will be invited to solve problems and various hypothetical exercises. Subsequently, an exchange between the views of the different groups will be issued.
The course provides participants with:
- ppt presentations of the lectures
- printed material for the working groups
- bibliography from the lecturers (tentative): https://uk.sagepub.com/en-gb/eur/the-design-of-animal-experiments/book252408,
