Lee, G.-H., Kim, K., Jo, W. 2023. Stress evaluation of mouse husbandry environments for improving laboratory animal welfare. Animals 13(2), 249.

Animal welfare is recognized as essential for the coexistence of humans and animals. Considering the increased demand and interest in animal welfare, many methods for improving animal welfare are being devised, but which method reduces...

Hobbiesiefken, U., Urmersbach, B., Jaap, A. et al. 2023. Rating enrichment items by female group-housed laboratory mice in multiple binary choice tests using an RFID-based tracking system. PLOS ONE 18(1), e0278709.

Laboratory mice spend most of their lives in cages, not experiments, so improving housing conditions is a first-choice approach to improving their welfare. Despite the increasing popularity of enrichment, little is known about the benefits...

Dickmann, J., Gonzalez-Uarquin, F., Reichel, S. et al. 2022. Clicker training mice for improved compliance in the catwalk test. Animals 12(24), 3545.

The CatWalk test relies on the run of mice across the platform to measure a constant speed with low variation. Mice usually require a stimulus to walk to the end of the catwalk. However, such...

Cohen, S., Ho, C. 2023. Review of rat (Rattus norvegicus), Mouse (mus musculus), Guinea pig (Cavia procellus), and rabbit (Oryctolagus cuniculus) indicators for welfare assessment. Animals 13(13), 2167.

The monitoring and assessment of animals is important for their health and welfare. The appropriate selection of multiple, validated, and feasible welfare assessment indicators is required to effectively identify compromises or improvements to animal welfare...

Chen, T., Zhou, Z.-Y., Liu, J.-Y. et al. 2022. Impact of partial bile duct ligation with or without repeated magnetic resonance imaging examinations in mice. Scientific Reports 12(1), 21014.

Partial bile duct ligation (pBDL) is considered a well-tolerated cholestatic model. Magnetic resonance imaging (MRI) is one of the most widely used tools in noninvasive imaging. However, no systematic studies have reported the possible effects...

Chen, J., Xu, X., Dalhaimer, P. et al. 2022. Tetra-primer amplification-refractory mutationsystem (ARMS)—PCR for genotyping mouse leptin gene mutation. Animals 12(19), 2680.

Due to spontaneous deficiency in leptin, ob/ob mice are one of the most commonly used experimental animal models in diabetes research. In this study, we reported a quick and easy-to-conduct genotyping method using tetra-primer amplification...

Bains, R. S., Forrest, H., Sillito, R. R. et al. 2023. Longitudinal home-cage automated assessment of climbing behavior shows sexual dimorphism and aging-related decrease in C57BL/6J healthy mice and allows early detection of motor impairment in the

Monitoring the activity of mice within their home cage is proving to be a powerful tool for revealing subtle and early-onset phenotypes in mouse models. Video-tracking, in particular, lends itself to automated machine-learning technologies that...

Assenmacher, C.-A., Lanza, M., Tarrant, J. C. et al. 2022. Post mortem study on the effects of routine handling and manipulation of laboratory mice. Animals 12(23), 3234.

Routine handling and manipulation of laboratory mice are integral components of most preclinical studies. Any type of handling and manipulation may cause stress and result in physical harm to mice, potentially leading to unintended consequences...

Ueno, H., Takahashi, Y., Murakami, S. et al. 2022. The prevention of home-cage grid climbing affects muscle strength in mice. Scientific Reports 12(1), 15263.

Experimenters and treatment methods are the major contributors to data variability in behavioral neuroscience. However, home cage characteristics are likely associated with data variability. Mice housed in breeding cages spontaneously exhibit behavioral patterns such as...
