RESUMEN
Recent years have seen increasing recognition of the scientific, economic and ethical benefits of the use of non-animal models in advancing preclinical research, giving reason to rethink the application and framework of the Three Rs. However, to benefit from the economic advantages of shifting to such alternative methods, and to realise Australia's drug development potential, legislative reform is essential. Such reform should be responsive to international regulations that encourage the use of animal-free methods, and be coupled with a corresponding re-evaluation of current Three Rs frameworks and principles. If these supportive changes, and the recommendations from the 2023 Australian Commonwealth Scientific and Industrial Research Organisation (CSIRO) Futures Non-animal models report, are implemented concurrently - with government support paramount- then a new gold standard for scientific research in Australia could be created in which the use of non-animal models and animal-free methods is the default.

In Mexico, it is not known which institutions use animals for scientific purposes. This work reports, based on data requested from the National Institute of Transparency, Access to Information and Protection of Personal Data (INAI), the types of institutions that use animals for research and how many of these have an ethics committee. Research centres, colleges, hospitals, national institutes, technical colleges, and public universities are the types of institutions that report using animals for experimentation. Only 54% of institutions have ethics committees. Mexican institutions from 2015 to 2021 used a total of 2,112,786 animals. Mammals are the most widely used animal group. The scientific purposes for using animals depend on the type of institution that uses them. In Mexico, it is necessary to update the regulations in order to regulate the use, protection and the care of laboratory animals.
En México se desconoce cuáles son las instituciones que utilizan animales con fines científicos. Se reporta, a partir de datos solicitados al Instituto Nacional de Transparencia, Acceso a la Información y Protección de Datos Personales (INAI), los tipos de instituciones que usan animales y cuántas poseen un comité interno para el cuidado y uso de los animales de laboratorio. Los centros de investigación, colegios, hospitales, institutos nacionales, tecnológicos y universidades públicas son los tipos de instituciones que reportaron usar animales. El 54% de las instituciones poseen comités de ética. Un total de 2,112,786 animales fueron usados por instituciones del 2015 al 2021. Los mamíferos es el grupo animal más utilizado. El uso de los animales se encuentra en función del tipo de institución que los utiliza. En México, es necesario actualizar la normatividad, con el fin de regular el uso, la protección y el cuidado de los animales de laboratorio.

OBJECTIVE: In this study, we added laboratory animal ethics education into both didactic sessions and practical sessions the general surgery laboratory course, with the didactic sessions focus on teaching the fundamental principles of laboratory animal ethics, while the practical sessions emphasize the application of these principles in laboratory classes and have assessed the changes in medical students' perception of laboratory animal ethics following medical students exposure to such education. METHODS: One hundred and eighty-nine third-year medical students from Wuhan University's Second Clinical College completed a laboratory animal ethics awareness questionnaire and a laboratory animal ethics written examination before and after laboratory animal ethics education. RESULTS: After receiving laboratory animal ethics education, the percentage of students who supported euthanasia for the execution of animals and humane treatment of laboratory animals were 95.2% and 98.8%, respectively, which did not differ from the 94.9% and 96.4% observed before the education. Moreover, there was a notable increase in the proportion of students who knew about regulations related to laboratory animals (from 39.9% to 57.1%), welfare issues (from 31.9% to 50.0%), and the 3R principle (from 30.4% to 58.9%) post-education, all statistically significant at P < 0.05. Test scores also showed improvement, with students scoring (93.02 ± 11.65) after education compared to (67.83 ± 8.08) before, a statistically significant difference. CONCLUSIONS: This research helps to provide information for the good practices of laboratory animal ethics education. After receiving laboratory animal ethics education, students are better able to treat laboratory animals in a correct animal ethical manner. Laboratory animal ethics education helps improve students' knowledge of laboratory animal ethics. Students' perception towards how the laboratory animal ethics course should be delivered may vary. Still, new courses or better organized courses on laboratory animal ethics education are required in order to provide students an in-depth understanding.

Nonanimal biomedical research methods have advanced rapidly over the last decade making them the first-choice model for many researchers due to improved translatability and avoidance of ethical concerns. Yet confidence in novel nonanimal methods is still being established and they remain a small portion of nonclinical biomedical research, which can lead peer reviewers to evaluate animal-free studies or grant proposals in a biased manner. This "animal methods bias" is the preference for animal-based research methods where they are not necessary or where nonanimal-based methods are suitable. It affects the fair consideration of animal-free biomedical research, hampering the uptake and dissemination of these approaches by putting pressure on researchers to conduct animal experiments and potentially perpetuating the use of poorly translatable model systems. An international team of researchers and advocates called the Coalition to Illuminate and Address Animal Methods Bias (COLAAB) aims to provide concrete evidence of the existence and consequences of this bias and to develop and implement solutions towards overcoming it. The COLAAB recently developed the first of several mitigation tools: the Author Guide for Addressing Animal Methods Bias in Publishing, which is described herein along with broader implications and future directions of this work.

Organizations that receive public money to conduct research using animals should be able to explain the importance of and need for that work. More generally, anyone who believes that properly conducted and regulated animal research either does or does not make the world a better place wants the public to understand why they hold their belief. In a world with divided support for animal research, honest communication about these issues is essential to develop sound public policy. Specifically, communication about animal research (or any type of research) needs to address the scientific, ethical, and regulatory considerations that underlie public policy decisions. This opinion article describes a 7-step communication strategy designed to address these issues. The 7 elements of this approach are 1) motivation, 2) the right mix of information, 3) a team approach, 4) respect for your audience, 5) determination and courage, 6) humility and honesty, and 7) persistence.

Due to the legal implantation of the 3R principle, the number of laboratory animals decreased significantly over the past 10 years. In this article, the historical development of animal experiments over the last decade will be presented in the context of the current regulations of the Animal Welfare Act. It points out bureaucratic obstacles to the approval of animal experiments, which jeopardize Germany as a research location for both academia and industry. The article presents constructive proposals for solutions. This should be done in accordance with the DFG recommendation to ensure efficient biomedical research while maintaining the highest animal welfare standards.

OBJECTIVES: The purpose of this systematic review was to examine how the scientific community in Europe that is involved with research with animals perceives and experiences the implementation of 3R (Replace, Reduce, Refine). METHODS: A systematic search of the literature published in the past ten years was performed in PubMed, Web of Science and Scopus. Publications were screened for eligibility using a priori inclusion criteria, and only empirical evidence (quantitative, qualitative, or mixed methodologies) was retained. Quantitative survey items were investigated by conducting a meta-analysis, and the qualitative data was summarized using an inductive meta-synthetic approach. Included publications were assessed using the Quality Assessment for Diverse Studies tool. RESULTS: 17 publications were included (eight quantitative, seven qualitative, two mixed-methods). The meta-analysis revealed that scientists are skeptical about achieving replacement, even if they believe that 3R improve the quality of experimental results. They are optimistic concerning the impact of 3R on research costs and innovation, and see education as highly valuable for the implementation of 3R. The meta-synthesis revealed four barriers (systemic dynamics, reification process, practical issues, insufficient knowledge) and four facilitators (efficient use of animals, caring for animals, regulatory uptake, supportive workplace environment). CONCLUSION: These findings show actionable levers at the local and systemic levels, and may inform regulators and institutions in their 3R policies. TRIAL REGISTRATION: The protocol was registered into the PROSPERO database under the number CRD42023395769.

Light is an environmental factor that is extrinsic to animals themselves and that exerts a profound influence on the regulation of circadian, neurohormonal, metabolic, and neurobehavioral systems of all animals, including research animals. These widespread biologic effects of light are mediated by distinct photoreceptors-rods and cones that comprise the conventional visual system and melanopsin-containing intrinsically photosensitive retinal ganglion cells (ipRGCs) of the nonvisual system that interact with the rods and cones. The rods and cones of the visual system, along with the ipRGCs of the nonvisual system, are species distinct in terms of opsins and opsin concentrations and interact with one another to provide vision and regulate circadian rhythms of neurohormonal and neurobehavioral responses to light. Here, we review a brief history of lighting technologies, the nature of light and circadian rhythms, our present understanding of mammalian photoreception, and current industry practices and standards. We also consider the implications of light for vivarium measurement, production, and technological application and provide simple recommendations on artificial lighting for use by regulatory authorities, lighting manufacturers, designers, engineers, researchers, and research animal care staff that ensure best practices for optimizing animal health and well-being and, ultimately, improving scientific outcomes.

What would it look like for researchers to take non-human animal rights seriously? Recent discussions foster the impression that scientific practice needs to be reformed to make animal research ethical: just as there is ethically rigorous human research, so there can be ethically rigorous animal research. We argue that practically little existing animal research would be ethical and that ethical animal research is not scalable. Since animal research is integral to the existing scientific paradigm, taking animal rights seriously requires a radical, wholesale reimagining of science.Trial registration: ClinicalTrials.gov identifier: NCT05340426.

Initial practices involving experimentation with animals can be found in ancient Greece, but animal experimentation as understood in the modern world first emerged in the Renaissance. In the 19th century, the French scientist Claude Bernard analysed the basis for animal experimentation using the Cartesian philosophical concept of animals being equivalent to machines. Yet as Claude Bernard's work on biology developed, it showed that animals, in particular the so-called sentient animals, did have forms of sensitivity and consciousness similar to humans. This led to the present-day moral concern with animal experimentation. The moral argument is expressed in philosophical terms in the Universal Declaration of Animal Rights and the law known as the "Three Rs", while the practical measures for implementation are set out in the European Directive 2010/63/EU on the protection of animals used for scientific purposes, and then as transposed and enforced in the different European Union Member States. This has led to improvements in the treatment of animals used for experimentation, and also allows scope for further improvements to be added in the future, particularly with alternative methods.
Title: Enjeux historiques et philosophiques de l'expérimentation animale. Abstract: Les ébauches de l'expérimentation animale peuvent être trouvées dans l'Antiquité, mais sa pratique moderne s'amorce à partir de la Renaissance. C'est Claude Bernard qui en analyse au XIXe siècle les bases, fondées sur le concept philosophique cartésien de l'animal-machine. Mais le développement même de la biologie bernardienne a révélé que les animaux, notamment les animaux dits « sentients ¼, disposent de processus de sensibilité et de conscience proches de ceux des êtres humains. D'où un souci moral qui se glisse, de nos jours, dans l'expérimentation animale et qui conduit à diverses améliorations du traitement des animaux d'expérience.

One response to calls for increased openness in animal research is to make protocols publicly accessible, but it is unclear what type of input the public would provide if given this opportunity. In this study we invited public responses to five different research projects, using non-technical summaries intended for lay audiences. Our aim was to assess the potential for this type of public consultation in protocol review, and a secondary aim was to better understand what types of animal research people are willing to accept and why. US participants (n = 1521) were asked (via an online survey) "Do you support the use of these (insert species) for this research", and responded using a seven-point scale (1 = "No", 4 = "Neutral", and 7 = "Yes"). Participants were asked to explain the reasons for their choice; open-ended text responses were subjected to thematic analysis. Most participants (89.7%) provided clear comments, showing the potential of an online forum to elicit feedback. Four themes were prevalent in participant reasoning regarding their support for the proposed research: 1) impact on animals, 2) impact on humans, 3) scientific merit, and 4) availability of alternatives. Participant support for the proposed research varied but on average was close to neutral (mean ± SD: 4.5 ± 2.19) suggesting some ambivalence to this animal use. The protocol describing Parkinson's research (on monkeys) was least supported (3.9 ± 2.17) and the transplant research (on pigs) was most supported (4.9 ± 2.02). These results indicate that public participants are sensitive to specifics of a protocol. We conclude that an online forum can provide meaningful public input on proposed animal research, offering research institutions the opportunity for improved transparency and the chance to reduce the risk that they engage in studies that are out of step with community values.

RESUMEN: El aspecto emocional del dolor no solo es controvertido en aves, peces y roedores, sino también en los seres humanos autoconscientes. Cuando el dolor emocional, o la insatisfacción, es vista como un mal intrínseco, evitarla o, al menos, minimizarla es un deber moral directo. El objetivo de este artículo es mostrar que no solo los modelos animales mamíferos que se utilizan en experimentación -rata (Rattus norvegicus) y ratón (Mus musculus)- sienten dolor, como reconocen universalmente las instituciones que se ocupan del bienestar animal, sino también los peces de laboratorio (Danio rerio) y los de producción (Salmo salar), y que este hecho es moralmente relevante desde el punto de vista de todas las concepciones de la moral que suelen enfrentarse en los debates morales públicos y académicos. En consecuencia, también en el caso de los peces habría que tener en cuenta indicadores de bienestar animal.
SUMMARY: The emotional aspect of pain is not only controversial in fish and rodents, but also in self-conscious humans. When pain or dissatisfaction is seen as an intrinsic evil, avoiding it or at least minimizing it is a moral duty direct. The objective of this article is to refer to pain, stress and the most widely used indices of animal welfare both in laboratory fish (Danio rerio) and production fish (Salmo salar) as well as in rat experimental animal models (Rattus norvegicus) and mouse (Mus musculus).

In the last century, progress in the knowledge of human diseases, their diagnosis and treatment have grown exponentially, due in large part to the introduction and use of laboratory animals. Along with this important progress, the need to provide training and guidance to the scientific community in all aspects related to the proper use of experimental animals has been indispensable. Animal research committees play a primary role in evaluating experimental research protocols, from their feasibility to the rational use of animals, but above all in seeking animal welfare. The Institutional Committee for the Care and Use of Animals (IACUC) has endeavored to share several relevant aspects in conducting research with laboratory animals. Here, we present and discuss the topics that we consider of utmost importance to take in the account during the design of any experimental research protocol, so we invite researchers, technicians, and undergraduate and graduate students to dive into the fascinating subject of proper animal care and use for experimentation. The main intention of these contributions is to sensitize users of laboratory animals for the proper and rational use of them in experimental research, as well as to disseminate the permitted and unpermitted procedures in laboratory animals. In the first part, the significance of experimental research, the main functions of IACUC, and the principle of the three R's (replacement, reduction, and refinement) are addressed.
