Background Considering the expected increase in the elderly population and the growing emphasis on aging-related biomedical research, the demand for aged laboratory animals has surged, challenging established husbandry practices. Our objective was to establish a...

Eliav, A., Ofri, R., Brust, K. et al. 2024. Improving rat welfare through the development of a peribulbar anaesthesia technique for ophthalmic procedures: A preliminary study. Laboratory Animals 58(2), 116–126.

Rats are a commonly used animal model for the study of the pathogenesis and novel treatments of glaucoma, which is induced experimentally using invasive, painful procedures. Peribulbar anaesthesia (PBA) is frequently used in people and...

Walczak-Gillies, Matthews, O., Fyfe, A. et al. 2023. Refining the welfare of immunocompromised mice receiving carbon tetrachloride (CCI4) to induce liver fibrosis. Animal Technology and Welfare 22(3), 237–239.

Our method provides evidence that we can alter CCI4 dosing and implement recovery techniques to enhance Animal Welfare, whilst maintaining sufficient levels of fibrosis in the liver.

Rashbrook, V. S., Denti, L., Ruhrberg, C. 2023. Tamoxifen exacerbates morbidity and mortality in male mice receiving medetomidine anaesthesia. Animal Welfare 32, e78.

Tamoxifen-induced CreER-LoxP recombination is often used to induce spatiotemporally controlled gene deletion in genetically modified mice. Prior work has shown that tamoxifen and tamoxifen-induced CreER activation can have off-target effects that should be controlled. However...

Spalinger, M., Schwarzfischer, M., Niechcial, A. et al. 2023. Evaluation of the effect of tramadol, paracetamol and metamizole on the severity of experimental colitis. Laboratory Animals 57(5), 529–540.

Application of dextran sodium sulfate (DSS) is often used to induce experimental colitis. Current state of the art is to refrain from the use of analgesics due to their possible interaction with the model. However...

Schelde, K., Rosenjack, J., Sonneborn, C. et al. 2023. A minimally invasive bronchoscopic approach for direct delivery to murine airways and application to models of pulmonary infection. Laboratory Animals 57(6), 611–622.

The laboratory mouse is used extensively for human disease modeling and preclinical therapeutic testing for efficacy, biodistribution, and toxicity. The variety of murine models available, and the ability to create new ones, eclipses all other...

Lopez-Echeverria, G., Alamaw, E., Gorman, G. et al. 2023. Comparing three formulations of buprenorphine in an incisional pain model in mice. JAALAS 62(6), 531–537.

This study compared the therapeutic effects in mice of 3 different formulations of buprenorphine. These formulations were standard buprenorphine hydrochloride (Bup-HCL) and 2 different extended-release buprenorphine formulations (Bup-ER and Ethiqa-XR [Bup-XR]). Drugs were evaluated based...

Ferguson, L. T., Rashied, A. A., Liang, Z. et al. 2023. A novel scoring system for humane endpoints in mice with cecal ligation and puncture-induced sepsis. Comparative Medicine 73(6), 446–460.

Animal-based research is essential to the study of sepsis pathophysiology, diagnostics, and therapeutics. However, animal models of sepsis are often associated with high mortality because of the difficulty in predicting imminent death based on premortem...

Caires, C. R. S., Bossolani-Martins, A. L. 2023. Which form of environmental enrichment is most effective in rodent models of autism? Behavioural Processes 211, 104915.

Environmental enrichment (EE) is known to produce experience-dependent changes in the brains and behaviors of rodents, and it has therefore been widely used to study neurodevelopmental disorders, including autism. Current studies show significant protocol variation...

Brake, M. E., Russ, B. P., Gansebom, S. et al. 2023. Effects of extended-release buprenorphine on mouse models of influenza. Comparative Medicine 73(6), 466–473.

Mice are widely used as small animal models for influenza infection and immunization studies because of their susceptibility to many strains of influenza, obvious clinical signs of infection, and ease of handling. Analgesia is rarely...
