Peterman, J.L., White, J.D., Calcagno, A. et al. 2020. Prolonged isolation stress accelerates the onset of Alzheimer’s disease-related pathology in 5xFAD mice despite running wheels and environmental enrichment. Behavioural Brain Researc

Research has demonstrated that stress can exacerbate AD pathology in transgenic mouse models of AD. The purpose of the present studies was to extend this work by determining whether a social stressor, isolation stress, would...

Mertens, S., Gass, P., Palme, R. et al. 2020. Effect of a partial cage dividing enrichment on aggression-associated parameters in group-housed male C57BL/6NCrl mice. Applied Animal Behaviour Science 224, 104939.

Group-housing is highly important for social animals. Group-housing of male mice in captivity though often leads to aggression with partially disastrous consequences for the animals as well as for the quality of experimental data. In...

Zidar, J., Weber, E. M., Ewaldsson, B. et al. 2019. Group and single housing of male mice: Collected experiences from research facilities in Sweden. Animals 9(12), 1010.

The mouse is the most commonly used mammal in scientific research, and housed in research facilities around the world. Mice are a social species, but when housing male mice together in a confined environment in...

Nøgaard, S. A., Sand, F. W., Sørensen, D. B. et al. 2020. Four- and six-hour urinary albumin excretion is a valuable alternative to 24-h urinary albumin excretion in male db/db mice. Animal Welfare 29(2), 143-149.

In mouse (Mus musculus) models of diabetic nephropathy (DN), one of the most important read-outs is the 24-h urinary albumin excretion (UAE). The 24-h urine collection is usually performed by single housing mice in metabolic...

In our facility, we use several hormone dependent tumour models with supplementation delivered via slow release subcutaneously implanted pellets, implanted via trochar. For example, breast tumours which rely on 17-β-Estradiol. Administration of E2 supplementation can...

Kaye, N. 2019. A technologist-led approach to altering the culture of care regarding blood sampling. Animal Technology and Welfare 18(3), 213-216.

This poster will describe the implementation by Animal Technologists and Named Persons of a well published refined bleeding technique. Establishing The Francis Crick Institute from legacy institutes required a standardised approach for many techniques, including...

Morgunowicz, A., Cavanagh, C., Nikitochkina, S. et al. 2019. Increased incidence of spontaneous seizures in laboratory mice in an IVC environment. Animal Technology and Welfare 18(3), 159-166.

Over the past decade, there has been an enormous shift away from the use of open top rodent cages to the use of individually ventilated cages (IVCs). This has brought with it many benefits, including...

Abdelrahman, A., Kumstel, S., Zhang, X. et al. 2019. A novel multi-parametric analysis of non-invasive methods to assess animal distress during chronic pancreatitis. Scientific Reports 9, 14084.

Ethical responsibility, legal requirements and the need to improve the quality of research create a growing interest in the welfare of laboratory animals. Judging the welfare of animals requires readout parameters, which are valid and...

Barabas, A. J., Aryal, U. K., Gaskill, B. N. 2019. Proteome characterization of used nesting material and potential protein sources from group housed male mice, Mus musculus. Scientific Reports 9, 17524.

Laboratory mice (Mus musculus) communicate a variety of social messages through olfactory cues and it is often speculated that these cues are preserved in nesting material. Based on these speculations, a growing number of husbandry...

Lidster, K., Owen, K., Browne, W. J. et al. 2019. Cage aggression in group-housed laboratory male mice: An international data crowdsourcing project. Scientific Reports 9, 15211.

Aggression in group-housed laboratory mice is a serious animal welfare concern. Further understanding of the causes of mouse aggression could have a significant impact on a large number of laboratory animals. The NC3Rs led a...
