Following allegations and graphic evidence of animal cruelty and neglect documented by ex-employee whistleblowers of Marineland Canada to the Toronto Star newspaper in late 2012, the ethics surrounding animal captivity have been increasingly contested in regional public discourse. Animal advocates in the Niagara region and beyond have been compelled to demand change at the infamous local captive animal park— whether it be welfare-oriented reform, or radical animal liberation. With this as a backdrop, this research explores the ideologies, experiences, and strategic tactics of anti-Marineland animal advocates; the sociopolitical issues surrounding the largely unexamined but serious issue of imprisoned animals as entertainers; and the ensuing governmental and corporatist attempts to squash dissent of anti-Marineland critics. Situated within a Critical Animal Studies theoretical paradigm as well as a flourishing global anti-captivity critique inspired by the film Blackfish, this project employs semi-structured interviews and participant observation methodologies to analyze advocates' views on captivity under capitalism and the effectiveness of their praxes. Finally, this research illuminates the nuances of the conventionally-upheld dualistic theoretical debate of animal welfare versus animal rights within zoo and aquaria entertainment contexts through an exploratory examination of advocates' complex ideological views.

The article focuses on three results of the study: "(1)Communicate your results outside the research. Write articles in popular and industry magazines. Speak at producer meetings and develop websites that can be used to transfer research results into practice. (2) Choose places (e.g. farms or plants) that have managers who believe in your research, and be prepared to spend a lot of time with the first place that uses your findings. (3) to fail. (4) Do not allow your technology to get tied up in patent disputes."

The articles discusses "processes which require the manipulation of genetic material to produce a substance which is administered to a farm animal or manipulation of the animal's own genetic material". The last section focuses on the ethical questions "from the viewpoint of the author who has had years of experience...".

This article examines the current legal regime applicable to animal-human combinations under the Assisted Human Reproduction Act (Canada). The Act prohibits as criminal offences the use of non-human reproductive material in humans, the use in humans of human reproductive material previously transplanted into a non-human life form, the creation of chimeras made from human embryos, and the creation for reproductive purposes of human/non-human hybrids. Additional animal-human combinations, such as transgenic life forms, may be regulated pursuant to section 11 of the Act in the future. The underlying concerns of the Act in establishing this regime appear to be the protection of human health and safety, human dignity and individuality, and the human genome. The Act seems calibrated to prohibit the creation of animal-human combinations that are currently unsafe and scientifically and ethically problematic, while leaving open the possibility of regulating other such combinations with more immediate scientific potential, although these also raise ethical questions. Currently, certain differences subsist in Canada between what is permissible for researchers and institutions funded by federal agencies and those in privately funded research. The development of the regulatory framework under the Act will reveal how freedom of research will be balanced against the need for scientifically valid and ethically justifiable research, and whether these differences will continue to apply.

La maladie de Wilson est une maladie héréditaire due à un déficit du transporteur du cuivre, l’ATP7B. Cette maladie se présente sous forme d’insuffisance hépatique aiguë ou chronique, pour lesquels le traitement médical actuel consiste en l’administration d’agents chélateurs, ce qui ne résulte cependant pas en une guérison complète de la maladie. La transplantation orthotopique du foie est le seul traitement définitif actuellement, avec tous les désavantages qu’elle comporte. Un traitement alternatif à cette option est donc souhaitable. Cette étude porte sur la faisabilité de la transplantation d’hépatocytes chez le modèle animal de la maladie de Wilson, le rat Long Evans Cinnamon (LEC), avec pour buts d’en déterminer la sécurité et l’efficacité tant sur le plan clinique (amélioration de la survie, prévention de l’hépatite) que pathologique. Douze rats LEC ont reçu une injection intrasplénique de 2,6 x 105 – 3,6 x 107 hépatocytes prélevés chez des rats donneurs de souche LE. Ils ont été suivis durant 6 mois puis sacrifiés. Ils ont ensuite été comparés à un groupe contrôle de douze autres rats LEC. Aucune différence significative n’a été notée au niveau du poids, du bilan hépatique et des concentrations de cuivre biliaire et hépatique. Cependant, une amélioration de l’activité oxydase de la céruloplasmine post-transplantation a été démontrée chez le groupe de rats transplantés (49,6 ± 31,5 versus 8,9 ± 11,7). Les rats transplantés ont aussi eu une amélioration sur tous les critères histologiques étudiés. Enfin, l’ARNm de l’atp7b a été retrouvé chez 58% des rats transplantés avec un taux d’expression de 11,9% ± 13,6 par rapport à un rat LE normal. L’immunohistochimie a quant à elle démontré la présence de l’atp7b chez tous les rats transplantés. Les résultats obtenus sont considérés favorables à ce traitement alternatif, et indiquent que la transplantation d’hépatocytes est une technique sécuritaire qui peut contribuer à renverser le processus pathologique en cours dans la maladie de Wilson.
