Schuster, C. J., Pang, D. S. J. 2018. Forced-air pre-warming prevents peri-anaesthetic hypothermia and shortens recovery in adult rats. Laboratory Animals 52(2), 142-151.

General anaesthesia disrupts thermoregulation in mammals, which can cause hypothermia. Decreases in core body temperature of 1℃ cause significant postoperative complications in humans, and peri-anaesthetic hypothermia in mice increases data variability, which can potentially increase...

ter Horst, E. N., Krijnen, P. A. J., Flecknell, P. et al. 2018. Sufentanil–medetomidine anaesthesia compared with fentanyl/fluanisone–midazolam is associated with fewer ventricular arrhythmias and deathmyocardial infarction in rats

To improve infarct healing following myocardial infarction in humans, therapeutic interventions can be applied during the inflammatory response. Animal models are widely used to study this process. However, induction of MI in rodents is associated...

Harikrishnan, V. S., Hansen, A. K., Abelson, K. S. P. et al. 2018. A comparison of various methods of blood sampling in mice and rats: Effects on animal welfare. Laboratory Animals 52(3), 253-264.

This study was conducted to investigate the effects of blood sampling on animal welfare in a total of 60 NTac:SD rats and 72 C57BL/6NTac mice of both sexes. Blood was sampled either by sublingual vein...

Hoffmann, M., Schwertassek, U., Seydel, A. et al. 2018. A refined and translationally relevant model of chronic DSS colitis in BALB/c mice. Laboratory Animals 52(3), 240-252.

Inflammatory bowel diseases (IBD) are chronic relapsing disorders of the gastrointestinal tract. Several mouse models for IBD are available, but the acute dextran sulfate sodium (DSS)-induced colitis model is mostly used for preclinical studies. However...

Tallent, B. R., Law, L. M., Rowe, R. K. et al. 2018. Partial cage division significantly reduces aggressive behavior in male laboratory mice. Laboratory Animals 52(4), 384 - 393.

Aggression in mice often results in injury leading to unplanned euthanasia or the initiation of protocols to isolate animals, thereby increasing research costs and straining resources. Here, we tested if adding a partial cage divider...

Nørgaard, S. A., Sand, F. B., Sørensen, D. B. et al. 2018. Softened food reduces weight loss in the streptozotocin-induced male mouse model of diabetic nephropathy. Laboratory Animals 52(4), 373-383.

The streptozotocin (STZ)-induced diabetic mouse is a widely used model of diabetes and diabetic nephropathy (DN). However, it is a well-known issue that this model is challenged by high weight loss, which despite supportive measures...

Lofgren, J., Miller, A. L., Shan Lee, C. C. et al. 2018. Analgesics promote welfare and sustain tumour growth in orthotopic 4T1 and B16 mouse cancer models. Laboratory Animals 52(4), 351-364.

Murine orthotopic cancer models often require surgery, potentially causing pain or distress. However, analgesics are often withheld because they may alter tumour development. Two orthotopically implanted cancers were investigated in mice pre-treated with meloxicam (10...

Abou-Ismail, U. A., Darwish, R. A., Ramadan, S. G. A. 2014. Should cages of laboratory rats be enriched physically or socially? Global Veterinaria 13(4), 570-582.

Experiments of environmental enrichment usually compare between group-housed rats in enriched and unenriched cages or between group-housed rats in enriched cages and single-housed rats in unenriched cages. This bias is mainly to maximize the chance...

Gjendal, K., Sørensen, D. B., Kiersgaard, M. K. et al. 2017. Hang on: An evaluation of the hemp rope as environmental enrichment in C57BL/6 mice. Animal Welfare 26(4), 437-447.

When introducing environmental enrichment in laboratory animals, positive and/or negative effects on behavioural and physiological parameters should be evaluated. This three-step randomised controlled trial in male C57BL/6 mice investigated the effect of supplementing the environment...

Kells, N. J., Beausoleil, N. J., Sutherland, M. A. et al. 2018. Electroencephalographic responses of anaesthetised rats to carbon dioxide inhalation. Animal Welfare 27(3), 215-223.

Exposure to high concentrations of CO2 is a common means of stunning and killing laboratory rodents. However, there is concern regarding the potential for animals to have aversive experiences, such as pain or breathlessness, prior...
