Soybean proteins: The Good, The Bad, The Healthy

Steve Gleddie, Ph.D. Agriculture and Agri-Food Canada

Soybeans are an excellent source of protein for humans and farm animals. However, they pose a problem to a small percentage of the population who suffer from soybean allergies. Since we can identify and manipulate the protein content and composition of seeds like soybean, it is possible to find lines of soybean that are hypoallergenic. We are attempting to do this by breeding out the proteins responsible for allergic reactions among the population. The beneficial properties of soybeans (a diet rich in soy helps to lower blood cholesterol levels) are also due to certain proteins in the seeds. We are attempting to boost the natural content of these beneficial proteins in soybeans to produce a food with improved nutritional properties.

 


De la double hélice à la GRC : évolution des techniques de typage d'ADN pour l'identification humaine au fil des ans

Chantal Frégeau, Ph.D. Services nationaux et recherche, Gendarmerie royale du Canada

Tout comme les empreintes digitales, les empreintes génétiques utilisées à des fins d'identification humaine ont révolutionné les procédés d'enquête judiciaire. Les nouvelles stratégies de typage d'ADN permettent de réduire de façon significative le temps requis pour établir des liens entre criminels suspects et le matériel biologique retrouvé sur la scène d'un crime. Ces mêmes procédés facilitent l'identification de victimes de désastres majeurs. L'évolution rapide des techniques de typage d'ADN sera présentée ainsi que l'impact de ces virages technologiques sur le système judiciaire.

 


Playing with Eggs and Sperm: Wisdom or Folly?

Barbara Vanderhyden, Ph.D. University of Ottawa, Ottawa Hospital Research Institute

On July 25, 1978 Louise Brown, the first baby to be conceived outside its mother's body, was born. The existence of Louise is possible because of a technique called in-vitro fertilization, one of a growing number of assisted reproductive technologies developed to help infertile people have children who are genetically their own. After more than 30 years, questions about these techniques continue to create ethical controversy, and are the subject of much legal and moral debate. Dr. Vanderhyden will provide an overview of these technologies, as well as explore some of the ethical issues associated with these techniques.

 


 

L'histoire de la chimie médicinale

Louis Barriault, Ph.D. Département de chimie, Université d'Ottawa

De nos jours, le chimiste médicinale conçoit et produit des médicaments qui vont être bénéfiques pour l'humanité. Avant le développement de la chimie médicinale, plusieurs pseudo-scientifiques ou guérisseurs ont élaboré toutes sortes de concoctions dont la plupart étaient peu efficaces et voir même mortelles. Le pouvoir guérisseur de ces composés était basé simplement sur des croyances et des observations. Avec ses découvertes, Lavoisier allait jeter les bases de la chimie moderne et un siècle plus tard Wolher et Perkins développèrent la chimie organique. Dans cette exposée, l'évolution de chimie médicinale au cours des 200 ans dernières années de même que la conception de médicaments seront présentées.

 


 

Agricultural Biotechnology: Sustainable Solutions for the 21st Century

Maria Trainer, Ph.D. New Substances Assessment and Control Bureau, Health Canada

Biotechnology already plays a significant role in all of our lives. We rely on it to bake bread, brew beer, treat diabetes; and catch criminals. It has revolutionized the way we live and will continue to do so for generations to come. In the coming years, climate change and population growth will place tremendous pressure on our global food supply. For example, food production will need to double in order to feed 9.5 billion people in 2050. Although there is no one-size-fits-all solution to this problem, the biotechnology industry will be a critical player in the development of innovative and sustainable solutions.

 


 

La bioéthique, au cœur du progrès médical

Karine Morin, Directrice, Programme GE3LS national, Génome Canada

Devrait-on tester un nouveau né pour une maladie génétique s'il n'existe aucun traitement? Comment les médecins doivent-ils discuter d'options de traitement médical avec des patients dont le profil génétique suggère qu'ils ne retireront aucun bénéfice? Voici certains dilemmes que pourraient présenter la « médicine personnalisée » qui se fonde sur le profil génétique des patients. Et c'est à la bioéthique que revient la tâche de proposer des réponses acceptables, autant au niveau des individus qu'au niveau de la société.

Pushing, Poking and Stretching Living Cells

Andrew Pelling, Ph.D. Department of Physics, University of Ottawa

We often think about cells as the basic units of life; small microcosms of biochemical reactions and complex physiological pathways. In textbooks cells are often represented as cartoons - static and unmoving. However, cells are incredibly dynamic! Moving and changing shape, they literally feel their environment by pulling and pushing on it. They even respond to physical touch. These physical cues affect cell biology at the most fundamental levels – affecting mitosis, stem cell differentiation and even the way they die. I will discuss our work pushing, poking and stretching living cells to understand how they interpret the physical factors that have profound effects on their physiology.

 


 

Overcoming the Current Limitations of Cryopreservation

Robert Ben, Ph.D. Department of Chemistry, University of Ottawa

The damage to cells and tissues during cryopreservation is extensive and results in dramatically decreased cell viability after thawing. This is the ultimate reason that the cryopreservation of many "precious" cell types and organs is not an effective strategy for biopreservation of such samples, even with the use of conventional cryoprotectants. Many organisms such as deep sea Teleost fish have evolved clever strategies to survive sub-zero environments. Through the diligent study of these naturally occurring compounds, our laboratory has successfully designed novel cryoprotectants that can overcome many of the current limitations associated with cryopreservation.

 


 

Stem Cell Based Treatment Helping Patients Now

Harry Atkins, M.D. Ottawa Hospital Research Institute; A Multiple Sclerosis patient

Join a physician and a patient who received a stem cell therapy for a presentation and discussion on the promises offered by stem cell research, and making them into a reality. Dr. Harry Atkins, Ottawa Hospital physician and scientist, will describe some of the new ways that stem cells can be used to treat patients with different illnesses. A patient, who has had his Multiple Sclerosis treated with a novel stem cell therapy, will provide their perspective on stem cell science and hopes for the future. This presentation promises to open minds and spark the interest of anyone who is interested in this new and exciting frontier of medical research.

 


Big Impact of Small Science: Nanotechnology and Bionanotechnology

Maria De Rosa, Ph.D. Department of Chemistry and Institute of Biochemistry, Carleton University

Nanotechnology seeks to make, measure, and manipulate useful devices and materials on an extremely small length scale, on the order of billionths of a metre. As nature has been very successful working at this length, it makes sense to look to biological building blocks, like DNA, for use in nanotech. In this presentation, we'll learn about nanotechnology and then look at some of the latest advances in DNA nanotechnology. Come learn how "DNA origami" might revolutionize electronics. How far away are we from useful DNA nanomachines? What concerns about DNA nanotechnology are real and what is just fear-mongering?

 


Forensic Science - Past and Present

Ron Fourney, Ph.D. Director, National Services and Research, Forensic Science and Identification Services

Be sure not to miss Dr. Fourney's fascinating presentation on DNA typing research. In the same manner that conventional fingerprinting analysis changed the course of human identification more than 100 years ago, "DNA Typing" has revolutionized forensic science and our quest for human identification. Learn about the history of this technology from the past to the present and how it has played a key role in the administration of justice

 


Environmental Biotechnology: Bioremediation and Biotransformation of Crude Oil

Kathlyn Kirkwood, Ph.D. Department of Chemical and Biological Engineering, University of Ottawa

Contamination of the environment with crude oil is unfortunately a common occurrence. Spills can occur during production, processing and transportation of oil, for example the recent devastating explosion and spill in the Gulf of Mexico. One of the most important technologies we have for cleaning up these sites is bioremediation, or the use of bacteria and fungi to consume the crude oil and transform it to non-toxic products. This talk will introduce the remarkable abilities of bacteria to break down chemicals we would consider wastes or pollutants, and discuss how we can apply this activity not only for clean-up but also to develop new industrial processes.
