Refinement Database

Database on Refinement of Housing, Husbandry, Care, and Use of Animals in Research

This database, created in 2000, is updated every three months with newly published scientific articles, books, and other publications related to improving or safeguarding the welfare of animals used in research.

Links to the full text for publications that appear in open access journals or are published on the AWI website are provided under the abstract.

Tips for using the database:

  • This landing page displays all of the publications in the database.
  • Use the drop-down menus to filter these publications by Animal Type and/or Topic.
  • Clicking on a parent category (e.g., Rodent) will include publications relating to all the items in that category (e.g., Chinchilla, Gerbil, Guinea pig, etc.).
  • You may also add a keyword to further narrow your search.
  • Please note that at this time, only publications dated 2010 or later (with some exceptions) can be filtered by Animal Type and Topic. Most publications older than 2010 can only be searched by keyword. 
Navarro-Castilla, A., Garrido, M., Hawlena, H. et al. 2021. Non-invasive monitoring of adrenocortical activity in three sympatric desert gerbil species. Animals 11(1), 75.

The study of the endocrine status can be useful to understand wildlife responses to the changing environment. Here, we validated an enzyme immunoassay (EIA) to non-invasively monitor adrenocortical activity by measuring fecal corticosterone metabolites (FCM)...

Nøgaard, S. A., Sand, F. W., Sørensen, D. B. et al. 2020. Four- and six-hour urinary albumin excretion is a valuable alternative to 24-h urinary albumin excretion in male db/db mice. Animal Welfare 29(2), 143-149.

In mouse (Mus musculus) models of diabetic nephropathy (DN), one of the most important read-outs is the 24-h urinary albumin excretion (UAE). The 24-h urine collection is usually performed by single housing mice in metabolic...

van der Vinne, V., Pothecary, C. A., Wilcox, S. L. et al. 2020. Continuous and non-invasive thermography of mouse skin accurately describes core body temperature patterns, but not absolute core temperature. Scientific Reports 10(1), 20680.

Body temperature is an important physiological parameter in many studies of laboratory mice. Continuous assessment of body temperature has traditionally required surgical implantation of a telemeter, but this invasive procedure adversely impacts animal welfare. Near-infrared...

Elmi, A., Galligioni, V., Govoni, N. et al. 2020. Quantification of hair corticosterone, DHEA and testosterone as a potential tool for welfare assessment in male laboratory mice. Animals 10(12), 2408.

Steroids, providing information regarding several biological patterns including stress and sexual behavior, have been investigated in different matrices in laboratory mice. Data regarding hair quantification, indicative of longer timespans when compared to blood and saliva...

Franco, N. H., Gerós, A., Oliveira, L. et al. 2019. ThermoLabAnimal – A high-throughput analysis software for non-invasive thermal assessment of laboratory mice. Physiology & Behavior, 207, 113-121.

Body temperature changes in laboratory mice are often assessed by invasive and stressful methods, which may confound the measurement. Infrared thermography is a possible non-invasive alternative, but the cost of standard thermal cameras, lack of...

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...

Rowland, N. E., Toth, L. A. 2019. Analytic and interpretational pitfalls to measuring fecal corticosterone metabolites in laboratory rats and mice. Comparative Medicine 69(5), 337–349.

Minimization and alleviation of stress are generally viewed as desirable aspects of laboratory animal management and use. However, achieving that goal requires an unambiguous and valid measure of stress. Glucocorticoid concentrations are commonly used as...

Skinner, M., Ceuppens, P., White, P. et al. 2019. Social-housing and use of double-decker cages in rat telemetry studies. Journal of Pharmacological and Toxicological Methods 96, 87-94.

Rat telemetry is widely used for biomedical research purposes and is used routinely in early pre-clinical drug development to screen for the potential cardiovascular risk of candidate drugs. Historically, these studies have been conducted in...

Mei, J., Riedel, N., Grittner, U. et al. 2018. Body temperature measurement in mice during acute illness: implantable temperature transponder versus surface infrared thermometry. Scientific Reports 8, 3526.

Body temperature is a valuable parameter in determining the wellbeing of laboratory animals. However, using body temperature to refine humane endpoints during acute illness generally lacks comprehensiveness and exposes to inter-observer bias. Here we compared...

Lipták, B., Kaprinay, B., Gáspárová, Z. 2017. A rat-friendly modification of the non-invasive tail-cuff to record blood pressure. Lab Animal 46(6), 251-253.

In animal models, blood pressure measurement methods can be either invasive (direct) or non-invasive (indirect). The non-invasive alternative involves applying a tail-cuff for blood pressure measurement. Current standardized restraint methods involve confining the laboratory animal...

Grant, C., Marks, L., Prior, H. 2017. Provision of food and water in rodent whole body plethysmography safety pharmacology respiratory studies – Impact on animal welfare and data quality. Journal of Pharmacological and Toxicological Methods 88(Part 1), 79-84.

Introduction: We evaluated the feasibility of providing food and water to rodents during whole body plethysmography (WBP) studies as a welfare improvement to standard conditions. Methods: Male Han Wistar rats or CD1 mice (n=8) were...
