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...

Chung, Y. H., Gulumian, M., Pleus, R. C. et al. 2022. Animal welfare considerations when conducting OECD test guideline inhalation and toxicokinetic studies for nanomaterials. Animals 12(23), 3305.

The OECD test guidelines for animal experiments play an important role in evaluating the chemical hazards. Animal tests performed using OECD guidelines, especially when the good laboratory practice (GLP) principle is applied, reduce the duplication...

Chrzanowska, A., Modlinska, K., Goncikowska, K. et al. 2022. Rat’s response to a novelty and increased complexity of the environment resulting from the introduction of movable vs. stationary objects in the free exploration test.

Most animals, including rats, show a preference for more complex environments. This is demonstrated particularly well when complexity increases due to the addition of new elements to the environment. The aim of the study was...

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...

Breuer, L., Mösch, L., Kunczik, J. et al. 2023. Camera-based respiration monitoring of unconstrained rodents. Animals 13(12), 1901.

Animal research has always been crucial for various medical and scientific breakthroughs, providing information on disease mechanisms, genetic predisposition to diseases, and pharmacological treatment. However, the use of animals in medical research is a source...

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...
