López-Salesansky, N., Mazlan, N. H., Whitfield, L. E. et al. 2016. Olfaction variation in mouse husbandry and its implications for refinement and standardization: UK survey of animal scents. Laboratory Animals 50(5), 362-369.

Olfaction plays a crucial role in mouse communication, providing information about genetic identity, physiological status of conspecifics and alerting mice to potential predators. Scents of animal origin can trigger physiological and behavioural responses that could...

Norton, W. B., Scavizzi, F., Smith, C. D. et al. 2016. Refinements for embryo implantation surgery in the mouse: Comparison of injectable and inhalant anesthesias – tribromoethanol, ketamine and isoflurane – on pregnancy and pup survival.

An essential aspect of genetically-engineered mice (GEM) is the ability to produce live animals after the appropriate injection procedure. Animals are produced by implantation of manipulated embryos into pseudopregnant females for gestation, parturition, and growth...

Lang, A., Schulz, A., Ellinghaus, A. et al. 2016. Osteotomy models – the current status on pain scoring and management in small rodents. Laboratory Animals 50(6), 433-441.

Fracture healing is a complex regeneration process which produces new bone tissue without scar formation. However, fracture healing disorders occur in approximately 10% of human patients and cause severe pain and reduced quality of life...

Jeger, V., Hauffe, T., Nicholls-Vuille, F. et al. 2016. Analgesia in clinically relevant rodent models of sepsis. Laboratory Animals 50(6), 418-426.

Postoperative analgesia in rodent sepsis models has been considerably neglected in the past. However, intentions to model clinical practice, increasing awareness of animal ethics, efforts to apply the 3Rs (replacement, reduction, refinement), and stricter legislation...

Tavera-Mendoza, L. E., Brown, M. 2017. A less invasive method for orthotopic injection of breast cancer cells into the mouse mammary gland. Laboratory Animals 51(1), 85-88.

Breast cancer is the most common type of cancer diagnosed in women, and the second most common cause of cancer-related deaths in women in North America. The use of laboratory mice in research is an...

Miranda, A., Pego, J. M., Correia-Pinto, J. 2017. Animal facility videoendoscopic intubation station: Tips and tricks from mice to rabbits. Laboratory Animals 51(2), 204-207.

Endotracheal intubation of laboratory animals is a common procedure shared by several research fields for different purposes, such as mechanical ventilation of anaesthetized animals, instillation of cytotoxic nanoparticles, infectious agents or tumour cells for induction...

Robinson-Junker, A., Morin, A., Pritchett-Corning, K. et al. 2017. Sorting it out: Bedding particle size and nesting material processing method affect nest complexity. Laboratory Animals 51(2), 170-180.

As part of routine husbandry, an increasing number of laboratory mice receive nesting material in addition to standard bedding material in their cages. Nesting material improves health outcomes and physiological performance in mice that receive...

Otano-Rivera, V., Boakye, A., Grobe, N. et al. 2017. A highly efficient strategy to determine genotypes of genetically-engineered mice using genomic DNA purified from hair roots. Laboratory Animals 51(2), 138-146.

Genotyping of genetically-engineered mice is necessary for the effective design of breeding strategies and identification of mutant mice. This process relies on the identification of DNA markers introduced into genomic sequences of mice, a task...

Freymann, J., Tsai, P.-P., Stelzer, H. D. et al. 2017. Impact of bedding volume on physiological and behavioural parameters in laboratory mice. Laboratory Animals 51(6), 601-612.

The standard housing temperature in animal facilities is substantially below the lower critical temperature of mice. This does not only endanger animal welfare, it can also jeopardize scientific research as cold stress has a major...
