Talbot, S. R., Struve, B., Wassermann, L. et al. 2022. RELSA—A multidimensional procedure for the comparative assessment of well-being and the quantitative determination of severity in experimental procedures. Frontiers in Veterinary Science 9, 93771

Good science in translational research requires good animal welfare according to the principles of 3Rs. In many countries, determining animal welfare is a mandatory legal requirement, implying a categorization of animal suffering, traditionally dominated by...

Swan, J., Boyer, S., Westlund, K. et al. 2023. Decreased levels of discomfort in repeatedly handled mice during experimental procedures, assessed by facial expressions. Frontiers in Behavioral Neuroscience 17, 1109886.

Mice are the most commonly used laboratory animal, yet there are limited studies which investigate the effects of repeated handling on their welfare and scientific outcomes. Furthermore, simple methods to evaluate distress in mice are...

Burbidge, C., Beresford, Z., Serrano-Galleg, V. 2023. Validating in-cage mouse enrichment. Animal Technology and Welfare 22(1), 63–67.

There is a wide variety of different types of mouse enrichment currently available, some items of which are more practical than others. Validating items used for providing enrichment can be time consuming and costly, nevertheless...

Quante, S. M., Siewert, V., Palme, R. et al. 2023. The power of a touch: Regular touchscreen training but not its termination affects hormones and behavior in mice. Frontiers in Behavioral Neuroscience 17, 1112780.

Touchscreen-based procedures are increasingly used in experimental animal research. They not only represent a promising approach for translational research, but have also been highlighted as a powerful tool to reduce potential experimenter effects in animal...

Palumbo, G., Kunze, L. H., Oos, R. et al. 2023. Longitudinal studies on Alzheimer disease mouse models with multiple tracer PET/CT: Application of reduction and refinement principles in daily practice to safeguard animal welfare during progressive ag

Longitudinal studies on mouse models related to Alzheimer disease (AD) pathology play an important role in the investigation of therapeutic targets to help pharmaceutical research in the development of new drugs and in the attempt...

Orosz, G. 2022. Mouse food hopper dividers for a refined feeding method. Animal Technology and Welfare 21(3), 160–176.

This project aimed to establish whether a different method of presenting diet “ad-libitum” to laboratory mice could lower the negative consequences of exceess food, such as decreased quality, palatability and increased cost. The main aim...

Nuber, M., Gonzalez-Uarquin, F., Neufurth, M. et al. 2022. Development of a 3D simulator for training the mouse in utero electroporation. PLOS ONE 17(12), e0279004.

In utero electroporation (IUE) requires high-level training in microinjection through the mouse uterine wall into the lateral ventricle of the mouse brain. Training for IUE is currently being performed in live mice as no artificial...

Müller, K., Lengheimer, T., Kral-Pointner, J. B. et al. 2022. Exposure to soiled bedding reduces abnormal repetitive behaviors in mice. Frontiers in Behavioral Neuroscience 16, 1062864.

Hygiene management protocols in laboratory mouse husbandries worldwide most commonly employ soiled bedding-exposed sentinel mice to monitor the occurrence of infections in mouse colonies. Using this approach, sentinel mice repeatedly receive a mixture of used...

Mieske, P., Hobbiesiefken, U., Fischer-Tenhagen, C. et al. 2022. Bored at home?—A systematic review on the effect of environmental enrichment on the welfare of laboratory rats and mice. Frontiers in Veterinary Science 9, 899219.

Boredom is an emotional state that occurs when an individual has nothing to do, is not interested in the surrounding, and feels dreary and in a monotony. While this condition is usually defined for humans...

Malik, A., Zavadil, J. A., Geusz, M. E. 2023. Using bioluminescence to image gene expression and spontaneous behavior in freely moving mice. PLOS ONE 18(1), e0279875.

Bioluminescence imaging (BLI) of gene expression in live animals is a powerful method for monitoring development, tumor growth, infections, healing, and other progressive, long-term biological processes. BLI remains an effective approach for reducing the number...
