Bacterial infections spread from one person to another person by means of a simple touch of contaminated surfaces in healthcare units. These infections have become untreatable to most existing antibiotics, thereby accounts for significant mortality rate. Polyamyna Nanotech is developing new antimicrobial coatings that prevent spreading dangerous bacterial infections in hospitals and health care units. Mitacs sponsored intern will evaluate our products by testing them against pathogenic bacteria. This would eventually boost the product development.
The mammalian liver is known for its regenerative property, capable of fully restoring mass and function after injury. However, when this process is in disarray, chronic liver diseases occur, for which the current solution is liver transplantation. Transplantation remains an imperfect solution as the supply is limited and rejection can happen. Today, 25% of patients waiting for transplantation die before a liver becomes available. This study aims to describe a regenerating liver at the cellular level to explore the alternatives to liver transplantation.
Heavy pesticide and antibiotic use are prevalent in modern agriculture and is an essential requirement to feed the ever-increasing human population. Their increased use, however, has also resulted in a loss of ecological biodiversity, environmental contamination, emerging pesticide/antibiotic resistance and is an economic burden to farmers, especially in low income nations. The research proposed aims to develop novel alternative agricultural bio-control technology centered around Bakers yeast, a common and non-toxic organism used in baking and brewing.
Wetlands provide critical habitat and valuable ecosystem services. Land use conversion in Ontario, however, has led to substantial wetland loss. The restoration of wetlands on agricultural properties has the potential to offset wetland loss, yet these wetlands are also susceptible to contamination by pesticides.
Grasslands are one of the most endangered habitat in North America. In Manitoba, over 90% has been lost in the last 100 years and with it a suite of prairie adapted species. The Poweshiek skipperling is one such species which in recent years has plummeted in abundance for unknown reasons. Less than 500 individuals remain in the wild and the grasslands of southeastern Manitoba represent one of the species last strongholds.
Agricultural practises in the North American prairies have intensified in the last several decades to increase food production, resulting in the drainage of up to 70% of prairie wetlands in some areas. Not surprisingly agricultural intensification is associated with the loss of biodiversity. Our research aims to assess whether retaining wetlands in agro-ecosystems can mitigate the effects of agricultural intensification on biodiversity, by monitoring wetland-derived insects and the breeding success of birds that depend on wetland-derived insects as prey.
The project will quantify spatial variation in food web quality associated with round goby / dreissenid mussel invasion and terrestrial dissolved organic carbon to understand how it may mediate the nutritional state (fatty acid content), body size, and Hg contaminant load of sportfish. We will work across existing spatial aquatic gradients in historical inorganic Hg sediment contamination, abundance of exotic round gobies and dreissenid mussels, and terrestrial DOC in the Upper St. Lawrence River. The Upper St.
Salt marshes are important coastal ecosystems because they provide many services to surrounding areas. Due to the high fertility of salt marsh soil, they have a long history of being converted to farmland in Maritime Canada. In recent years, there has been growing interest in restoring salt marshes to protect against coastal erosion, mitigate sea level rise, and provide increased habitat for birds, fish, etc.
