Atkinson, J., Boden, T., Mocho J.-P. et al. 2021. Refining the unilateral ureteral obstruction mouse model: No sham, no shame. Laboratory Animals 55(1), 21-29.

Fibrosis, as a common final pathway in many renal diseases, contributes significantly to the decline of organ function and to progression to end-stage renal disease. To establish therapeutic interventions that target fibrosis, animal models are...

Schalbetter, S. M., Mueller, F. S., Scarborough, J. et al. 2021. Oral application of clozapine-N-oxide using the micropipette-guided drug administration (MDA) method in mouse DREADD systems. Lab Animal 50(3), 69-75.

The designer receptor exclusively activated by designer drugs (DREADD) system is one of the most widely used chemogenetic techniques to modulate the activity of cell populations in the brains of behaving animals. DREADDs are activated...

Preece, C., Alghadban, S., Bouchareb, A. et al. 2021. Replacement of surgical vasectomy through the use of wild-type sterile hybrids. Lab Animal 50(2), 49-52.

For the production and rederivation of mouse strains, pseudopregnant female mice are used for embryo transfer and serve as surrogate mothers to support embryo development to term. Vasectomized males are commonly used to render pseudopregnancy...

Kendall, L. V., Singh, B., Bailey, A. L. et al. 2021. Pharmacokinetics and efficacy of a long-lasting, highly concentrated buprenorphine solution in mice. JAALAS 60(1), 64-71.

Buprenorphine is a commonly used opioid for mitigating pain in laboratory mice after surgical procedures; however, the dosing interval necessary for standard buprenorphine may require treatment every 4 to 6 h to maintain an adequate...

Hickman, D. L. 2021. Wellbeing of mice euthanized with carbon dioxide in their home cage as compared with an induction chamber. JAALAS 60(1), 72-76.

The AVMA Guidelines on Euthanasia state that, to decrease potential distress of animals, the home cage should be used for the euthanasia of mice. The current study evaluated this recommendation by comparing behavioral and physiologic...

Oatess, T. L., Harrison, F. E., Himmel, L. E. et al. 2021. Effects of acrylic tunnel enrichment on anxiety-like behavior, neurogenesis, and physiology of C57BL/6J mice. JAALAS 60(1), 44-53.

Environmental enrichment for mice lags behind the standard enrichment offered to other laboratory rodents due to concerns about environmental variability and, in specific contexts, aggression. Our objective in this study was to evaluate concerns that...

Tataryn, N. M., Buckmaster, C. A., Schwiebert, R. et al. 2021. Comparison of four beddings for ammonia control in individually ventilated mouse cages. JAALAS 60(1), 37-43.

Ammonia control is an important characteristic of rodent bedding materials. Among natural bedding materials, corncob bedding provides excellent ammonia control but contains estrogenic compounds and is ingested by mice. By comparison, processed cellulose bedding products...

Allen, P. S., Lawrence, J., Stasula, U. et al. 2021. Effects of compressed paper bedding on mouse breeding performance and recognition of animal health concerns. JAALAS 60(1), 28-36.

The combination of bedding substrate and nesting material within the microenvironment of mice is an important consideration for animal care programs in regard to optimizing animal wellbeing. We used 3 general or breeding mouse colonies...

Burlingame, L. A., Gaskill, B. N., Lofgren, J. L. S. 2021. Identification of sick or dead mice (Mus musculus) housed with 6 grams of crinkle paper nesting material. JAALAS 60(1), 18-27.

Although nesting material is beneficial to the welfare of laboratory mice, provision of appropriate amounts may impair visualization of the mice. In anticipation of our academic research institution transitioning to providing 6 grams of nesting...

Cantara, S. I., Blas-Machado, U., Zhao, X. et al. 2020. Comparative effects of 1/4-inch and 1/8-inch corncob bedding on cage ammonia levels, behavior, and respiratory pathology of male C57BL/6 and 129S1/Svlm mice. JAALAS 59(6), 695-702.

Corncob is a common bedding material used in laboratory rodents, but little is known about differences in the effects of the 2 available sizes on rodent models and health. This study compared the effects of...
