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...

Xie, W., Lorenz, M., Poosch, F. et al. 2022. 3D-printed lightweight dorsal skin fold chambers from PEEK reduce chamber-related animal distress. Scientific Reports 12(1), 11599.

The dorsal skinfold chamber is one of the most important in vivo models for repetitive longitudinal assessment of microcirculation and inflammation. This study aimed to refine this model by introducing a new lightweight chamber made...

Novak, J., Jaric, I., Rosso, M. et al. 2022. Handling method affects measures of anxiety, but not chronic stress in mice. Scientific Reports 12(1), 20938.

Studies in mice have shown that less aversive handling methods (e.g. tunnel or cup handling) can reduce behavioural measures of anxiety in comparison to picking mice up by their tail. Despite such evidence, tail handling...

Kloefkorn H, Aiani, L. M., Lakhani, A. et al. 2020. Noninvasive three-state sleep-wake staging in mice using electric field sensors. Journal of Neuroscience Methods 344, 108834.

Study Objective: Validate a novel method for sleep-wake staging in mice using noninvasive electric field (EF) sensors. Methods: Mice were implanted with electroencephalogram (EEG) and electromyogram (EMG) electrodes and housed individually. Noninvasive EF sensors were...
