Regan, D., Garcia, K., Thamm, D. 2018. Clinical, pathological, and ethical considerations for the conduct of clinical trials in dogs with naturally occurring cancer: A comparative approach to accelerate translational drug development.

The role of comparative oncology in translational research is receiving increasing attention from drug developers and the greater biomedical research community. Pet dogs with spontaneous cancer are important and underutilized translational models, owing to dogs’...

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...

Koski, S. K., Leino, S., Rannanpää, S. et al. 2019. Implementation of improved postoperative care decreases the mortality rate of operated mice after an abundant 6-hydroxydopamine lesion of nigrostriatal dopaminergic neurons. Scandinavian

A mouse model of Parkinson’s disease with an abundant lesion of nigrostriatal dopaminergic neurons can be achieved by stereotactic injection of 6-hydroxydopamine into the medial forebrain bundle. However, postoperative mortality can be excessively high without...

Redaelli, V., Papa, S., Marsella, G. et al. 2019. A refinement approach in a mouse model of rehabilitation research. Analgesia strategy, reduction approach and infrared thermography in spinal cord injury. PLOS ONE 14(10), e0224337.

The principles of Refinement, Replacement and Reduction (3R’s) should be taken into account when animals must be used for scientific purpose. Here, a Reduction / Refinement approach was applied to the procedure of spinal cord...

Harikrishnan, V. S., Krishnan, L. K., Abelson, K. S. P. 2019. A novel technique to develop thoracic spinal laminectomy and a methodology to assess the functionality and welfare of the contusion spinal

This study reports the advantage of a novel technique employing a motorised dental burr to assist laminectomy over the conventional manual technique at T10-T11 vertebra level in a rat model of spinal cord injury. Twenty-four...

Jarvi, J., Tewodros, M., Wang, M. et al. 2016. Refining the PDX mouse model: Development of a less invasive and disposable tumor engraftment process. Laboratory Animal Science Professional 4(1) (March), 47-51.

Patient-derived xenograft (PDX) models are created using fragments of human tumors subcutaneously implanted into immunodeficient mice. Solid tumor engraftment of mice is commonly performed with a 10-13 gauge trocar needle under general anesthesia. In this...

Gabriel, S. M., Riley, K. M., Spinks, W. A. et al. 2017. Husbandry, care and enrichment of diabetic Sinclair swine in the laboratory environment. Laboratory Animal Science Professional 5(3) (September), 53-57.

Health monitoring, enrichment, training procedures and techniques, as well as instructions for the care of vascular access ports, are outlined in this paper. The procedures described herein helped maintain a successful, long-term research population of...

Heyworth, C. 2019. Inventive enrichment to facilitate weight gain in the common marmoset (Callithrix jacchus) during invasive studies. Laboratory Animal Science Professional 7(4) (December), 38-41.

To provide the highest standard of care to marmosets during invasive surgical studies, studies that often lead to weight loss, it is paramount to call upon inherent species-specific enrichment tactics to mitigate weight loss. Weight...

Jensen, T. L., Kiersgaard, M. K., Mikkelsen, L. F. et al. 2019. Fasting of male mice – Effects of time point of initiation and duration on clinical chemistry parameters and animal welfare. Laboratory Animals 53(6), 587–597.

Fasting of mice is a common procedure, which can affect the outcome of the study as well as animal welfare. In this study, we assess the effects of fasting, fasting duration and fasting initiation time...

Resasco, A., Carranza Martin, A. C., Ayala, M. A. et al. 2019. Non-aversive photographic measurement method for subcutaneous tumours in nude mice. Laboratory Animals 53(4), 352–361.

We have developed a new method for the measurement of subcutaneous tumour volume which consists in taking photographs of mice in their home cages, to refine the standard method of measurement with calipers. We consider...
