Singleton, S., Nefla, M., Dennison, N. et al. 2020. Assessing pain in models of rheumatoid arthritis. Animal Technology and Welfare 19(2), 149-152.

A hallmark symptom of rheumatoid arthritis in humans is painful swollen joints. Pain can manifest before any inflammation is noticeable as well as persist long after inflammation has resolved. In rodent models of arthritis, ankle...

Stevens, C., Finnegan, E., Clarkson, J. et al. 2020. Report of the 2019 RSPCA/UFAW Rodent Welfare meeting. Animal Technology and Welfare 19(2), 101-111.

The RSPCA/UFAW Rodent Welfare Group has held a one-day meeting every autumn for the last 26 years, so that its members can discuss current welfare research, exchange views on welfare issues, and share experiences of...

Reinhardt, V. (ed.) 2020. It’s Okay to Cry - Discussions by the Laboratory Animal Refinement & Enrichment Forum [LAREF], Volume V. Animal Welfare Institute, Washington, DC.

This is the 5th volume of selected discussions that took place on the electronic Laboratory Animal Refinement & Enrichment Forum between February 2016 and December 2019. The forum was created in October 2002; it allows...

Bengtsson, C., Eriksson, M. 2020. Handling and training of mice and rats results in calmer animals during experimental procedures. AWI Quarterly 69(2) Summer, 6-8.

This article describes the handling and training protocols for mice and rats in preparation for their use in toxicology studies at the Research Institutes of Sweden (RISE).

Tang, W., Zillmann, U., Sprengel, R. 2020. Alternative anesthesia of neonatal mice for global rAAV delivery in the brain with non-detectable behavioral interference in adults. Frontiers in Behavioral Neuroscience 14, 115.

Viral-transduced gene expression is the current standard for cell-type-specific labeling and cell tacking in experimental neuroscience. To achieve widespread gene expression, a viral delivery method to neonatal rodents was introduced more than two decades ago...

Feige-Diller, J., Krakenberg, V., Bierbaum, L. et al. 2020. The effects of different feeding routines on welfare in laboratory mice. Frontiers in Veterinary Science 6, 479.

The accepted norm in most laboratories around the globe is feeding laboratory mice an ad libitum diet, although several health impairments are well-established. In contrast, reducing the animals' body weight by feeding them less food...

Turner, P. V., Hickman, D. L., van Luijk, J. et al. 2020. Welfare impact of carbon dioxide euthanasia on laboratory mice and rats: A systematic review. Frontiers in Veterinary Science 7, 411.

Background: There has been increased concern about the suitability of CO2 as a method for euthanasia of laboratory mice and rats, including the potential discomfort, pain or distress that animals may experience prior to loss...

Blok, J., Black, D. A., Petersen, J. et al. 2020. Environmental enrichment rescues visually-mediated behavior in Ten-m3 knockout mice during an early critical period. Frontiers in Behavioral Neuroscience 14, 22.

Environmental enrichment (EE) has been shown to promote neural plasticity. Its capacity to induce functional repair in models which exhibit profound sensory deficits due to aberrant axonal guidance has not been well-characterized. Ten-m3 knockout (KO)...

Zhang, X., Kumstel, S., Tang, G. et al. 2020. A rational approach of early humane endpoint determination in a murine model for cholestasis. ALTEX 37(2), 197-207.

Reduction of animal suffering during in vivo experiments is usually ensured by continuously monitoring the health status using a score sheet and by applying humane endpoints. However, most studies do not evaluate the plausibility of...
