Hankenson, F. C., Marx, J. O., Gordon, C. J. et al. 2018. Effects of rodent thermoregulation on animal models in the research environment. Comparative Medicine 68(6), 425–438.

To best promote animal wellbeing and the efficacy of biomedical models, scientific, husbandry, and veterinary professionals must consider the mechanisms, influences, and outcomes of rodent thermoregulation in contemporary research environments. Over the last 2 decades...

Rytlewski, J. D., Childress, P. J., Scofield, D. C. et al. 2018. Cohousing male mice with and without segmental bone defects. Comparative Medicine 68(2), 131–138.

Spaceflight results in bone loss like that associated with osteoporosis or decreased weight-bearing (for example, high-energy trauma such as explosive injuries and automobile accidents). Thus, the unique spaceflight laboratory on the International Space Station presents...

Collymore, C., Kent, L., Ahn, S. K. et al. 2018. Humane endpoints for guinea pigs used for Mycobacterium tuberculosis vaccine research. Comparative Medicine 68(1), 41–47.

Guinea pigs are a commonly used model for tuberculosis vaccine research. Loss of body weight is the most frequently described humane endpoint for animals used in these studies. During a chronic study, we noted labored...

Herndon, N. L., Bandyopadhyay, S., Hod, E. A. et al. 2016. Sustained-release buprenorphine improves postsurgical clinical condition but does not alter survival or cytokine levels in a murine model of polymicrobial sepsis. Comparative Medicin

Cecal ligation and perforation (CLP) is a common technique for studying sepsis in mice. Because of the invasiveness of the procedure and its effects on clinical condition, many animal care and use committees require the...

Wang, H., Li, Q, Tang, H. et al. 2019. The activated newborn neurons participate in enriched environment induced improvement of locomotor function in APP/PS1 mice. Brain and Behavior 9(7), e01316.

Alzheimer's disease (AD) is an age‐related neurodegenerative disorder. One of the pathological features of AD is neuronal loss in brain regions associated with cognition, particularly the hippocampus. An enriched environment (EE) can facilitate neuronal plasticity...

Taniuchi, T., Ohgi, A., Nishikawa, M. 2019. Returning to home cage serves as an effective reward for maze learning in rats. Behavioural Processes 164, 175-177.

This study examined the effectiveness in rats of ‘returning to home cage’ as a reward for learning a Lashley III maze. Rats could return to their home cage directly (Direct HC group) or they could...

Blizard, D. A., Weinheimer, V. K, Klein, L. C. et al. 2006. 'Return to home cage' as a reward for maze learning in young and old genetically heterogeneous mice. Comparative Medicine 56(3), 196-201.

Recent studies have shown that 'return to home cage' can serve as a reward for maze learning in adult male mice. The present study examined whether the same reward is an effective motivator of learning...

Modlinska, K., Chrzanowska, A., Pisula, W. 2019. The impact of changeability of enriched environment on exploration in rats. Behavioural Processes 164, 78-85.

Although the positive effect of environmental enrichment on animals’ cognitive capacities is well-known, it remains unclear what role changeability plays in this context. Our study aims to analyse the impact of environmental changeability on the...

Mora-Gallegos, A., Fornaguera, J. 2019. The effects of environmental enrichment and social isolation and their reversion on anxiety and fear conditioning. Behavioural Processes 158, 59-69.

Animal models of fear and anxiety provide important insight into anxiety-related symptoms in humans. Environmental physical conditions and social contact influence behavior and brain plasticity particularly at early developmental stages and have long lasting effects...
