NIGEL VAN LOAN La femme de Nigel Van Loan, Patricia, est décédée de la SLA en 2007, une maladie neurodégénérative mortelle, qui a aussi entraîné le décès de sa mère et de ses trois sœurs. Bien qu’elle fût soulagée d’enfin savoir de quoi elle souffrait, elle était envahie par la peur et éprouvait un profond sentiment d’appréhension et de panique — « Je ne savais vraiment pas comment je pourrais vivre avec la SLA sans devenir folle », avait-elle écrit sur le site Web de SLA Canada. Patricia a pu vivre à la maison jusqu’à sa mort grâce au progrès réalisé dans la recherche sur la SLA et à l’équipement prêté par la Société, qui lui a permis de se déplacer, d’être transportée dans les escaliers, de prendre une douche ou un bain et de sortir du lit. Après le décès de Patricia, Nigel s’est engagé auprès de SLA Canada et il est toujours membre de son comité de services à la clientèle, exerçant des pressions sur le gouvernement afin d’obtenir du financement pour la recherche et amassant des fonds pour la Société, dans le but de perpétuer la mémoire de sa femme — et parce que la SLA est une affaire de famille (ses deux fils et ses petits-enfants pourraient être porteurs du gène).

  • Maud Menten, a Physician and Biochemist
    Maud Menten Canadian medical researcher Maud Menten (1879-1960) has been called the "grandmother of biochemistry," a "radical feminist 1920s flapper," and a "petite dynamo." Not only was she an author of Michaelis-Menten equation for enzyme kinetics (like the plot in indigo in my portrait), she invented the azo-dye coupling for alkaline phosphatase, the first example of enzyme histochemistry, still used in histochemistry imaging of tissues today (which inspired the histology background of the portrait), and she also performed the first electrophoretic separation of blood haemoglobin in 1944! Born in Port Lambton, Ontario, she studied at the University of Toronto, earning her bachelor's in 1904, and then graduated from medical school (M.B., bachelor's of medicine) in 1907. She published her first paper with Archibald Macallum, the Professor of Physiology at U of T (who went on to set up the National Research Council of Canada), on the distribution of chloride ions in nerve cells in 1906. She worked a year at the Rockefeller Institute in New York, where along with Simon Flexner, first director of the Institute, she co-authored a book on radium bromide and cancer, the first publication produced by the Institute - barely 10 years after Marie Curie had discovered radium. She completed the first of two fellowships at Western Reserve University (now Case Western Reserve University), then she earned a doctorate in medical research in 1911 at U of T. She was one of the first Canadian women to earn such an advanced medical degree. She then moved to Berlin (travelling by boat, unfazed by the recent sinking of the Titanic) to work with Leonor Michaelis.

  • Stem Cell Strategy by Establishing the Till & Mcculloch Medicines of Tomorrow Innovation Fund
    A Pre-Budget Submission to the House of Commons Standing Committee on Finance To Implement the Canadian Stem Cell Strategy By Establishing The Till & McCulloch Medicines of Tomorrow Innovation Fund James Price President & CEO Canadian Stem Cell Foundation February 9, 2016 EXECUTIVE SUMMARY Stem cells represent the biggest innovation in medicine of the last half century. These cells have the power to cure many diseases for which current medical practice can only provide symptomatic relief and chronic care – a reality that is straining health care systems in Canada and in countries around the globe. Stem cells are a hallmark of Canadian innovation. They were first discovered in Canada and Canada is one of the top three countries in stem cell R&D, with our scientists ranking among the best in the world. Recent investments, such as the Government’s $20-million commitment to establish a cell-manufacturing facility in Toronto and the $114-million Medicine By Design grant for the University of Toronto, will help Canada move forward. However, major commitments by competitor jurisdictions – most notably California, with its investment of $3 billion, and Japan, with an investment of $1 billion in stem cells and regenerative medicine -- challenge Canada’s leadership in this sector of the knowledge economy. Moreover, Canada lacks a national plan to succeed in the coming cell therapy and regenerative medicine boom. The Canadian Stem Cell Strategy -- created in consultation with 150 scientists, medical doctors, leaders from major health charities, industry experts, investors and philanthropists – will: • deliver up to 10 new curative therapies within 10 years; • transform health care and ease the strain on the health system; and • attract private investment and generate 12,000 jobs for Canadians.

  • A Comparative Study of Canada and Mexico.” Studies in History and Philosophy of Biological and Biomedical Sciences (71), 8-16
    William Leeming and Ana Baharona. 2018. “Synthesis, Convergence and the Early Adoption of Cytogenetics in Medicine: A Comparative Study of Canada and Mexico.” Studies in History and Philosophy of Biological and Biomedical Sciences (71), 8-16. (Accepted Author Version) Authors: William Leeming and Ana Baharona Title: Synthesis, Convergence and Differences in the Entangled Histories of Cytogenetics in Medicine: A Comparative Study of Canada and Mexico Abstract: It is now commonplace for historians to say medical genetics began around sixty years ago with the synthesis and convergence of human genetics and cytological techniques in European centres which, in turn, were disseminated to centres in the United States in a more or less straightforward manner to become a new field of expertise in medicine and clinical research, i.e., cytogenetics. In this article, we show how the early histories of cytogenetics in Canada and Mexico unfolded against strikingly different backgrounds in clinical research and the delivery of health care. A key argument follows that the field of cytogenetics did not necessarily come together and develop the same way in all countries. The article begins with a brief background to the history of human cytogenetics. There follows two sections outlining the early adoption of cytogenetics in Canada and Mexico. Conclusions are then drawn using comparisons of the different ways local determinants affected adoption. This leads, in a final step, to suggestions for directions for future study concerning the ways circuits of practices, collaborative research, and transfers of knowledge have shaped the ways that cytogenetics has been organised in medicine around the world. Keywords: Medical Genetics, Cytogenetics, Karyotyping, Transnational perspective on history, Entangled histories 1 1.
