Katz, E. M., Huss, M. K., Jampachaisri, K. et al. 2021. Buprenorphine, but not lidocaine, effectively attenuates post-operative thermal hypersensitivity in an incisional model in neonatal rats (Rattus norvegicus). Scandinavian Journal of

There is limited information on safe and effective neonatal rodent analgesia. The aim of this study was to evaluate the efficacy and duration of analgesia provided by buprenorphine (Bup) and lidocaine (Lid) in an incisional...

Descovich, K. A., Richmond, S. E., Leach, M. C. et al. 2019. Opportunities for refinement in neuroscience: Indicators of wellness and post-operative pain in laboratory macaques. Alternatives to Animal Experimentation 36(4), 535-554.

Being able to assess pain in nonhuman primates undergoing biomedical procedures is important for preventing and alleviating pain, and for developing better guidelines to minimize the impacts of research on welfare in line with the...

Owen, J. P., Kelsh, R. N. 2021. A suitable anaesthetic protocol for metamorphic zebrafish. PLOS ONE 16(3), e0246504.

Zebrafish are frequently used as a means to investigate development. These studies increasingly require repeated anaesthesia of zebrafish during juvenile (i.e. metamorphic) stages. The effects of anaesthesia during this time remain poorly studied. The aim...

Blaney, A., Jampachaisri, K., Huss, M. K. et al. 2021. Sustained release buprenorphine effectively attenuates postoperative hypersensitivity in an incisional pain model in neonatal rats (Rattus norvegicus). PLOS ONE 16(2), e0246213.

Despite the need for safe and effective postoperative analgesia in neonates, research regarding pain management in neonatal rodents is relatively limited. Here, we investigate whether sustained release buprenorphine (Bup SR) effectively attenuates thermal hypersensitivity in...

Guisnet, A., Maitra, M., Pradhan, S. et al. 2021. A three-dimensional habitat for C. elegans environmental enrichment. PLOS ONE 16(1), e0245139.

As we learn more about the importance of gene-environment interactions and the effects of environmental enrichment, it becomes evident that minimalistic laboratory conditions can affect gene expression patterns and behaviors of model organisms. In the...

Smith, B. L., Lyons, C. E., Correa, F. G. et al. 2017. Behavioral and physiological consequences of enrichment loss in rats. Psychoneuroendocrinology 77, 37-46.

Significant loss produces the highest degree of stress and compromised well-being in humans. Current rodent models of stress involve the application of physically or psychologically aversive stimuli, but do not address the concept of loss...

Morano, R., Hoskins, O., Smith, B. L. et al. 2019. Loss of environmental enrichment elicits behavioral and physiological dysregulation in female rats. Frontiers in Behavioral Neuroscience 12, 287.

Chronic stress drives behavioral and physiological changes associated with numerous psychiatric disease states. In rodents, the vast majority of chronic stress models involve imposition of external stressors, whereas in humans stress is often driven by...

Slavík, O., Horký, P., Velíšek, J., et al. 2020. Pupil size variation as a response to stress in European catfish and its application for social stress detection in albino conspecifics. PLOS ONE, 15(12), e0244017.

Hormonal changes such as increased cortisol level in blood plasma in response to stress and social environmental stimuli are common among vertebrates including humans and typically accompanied by other physiological processes, such as changes in...

Williams, W. R. 2021. Edible nail polish as a novel enrichment strategy for single-housed nonhuman primates. Laboratory Animal Science Professional 9(2) (March/April), 50-51.

At the University of Oklahoma Health Sciences Center, NHPs may need to be singly housed for research purposes or veterinary care, and it can be challenging to keep them optimally enriched. This sometimes results in...
