Smart Particles to Prevent COVID-19 Infection & Complications

The COVID-19 pandemic has had an unprecedented global effect. While social distancing and proper PPE can minimize the spread of the virus, at risk populations have remained vulnerable. With additional waves of infection are likely to occur, there is an urgent need for an innovative protective solution. In the current project, we will repurpose a patented platform technology from the Sheardown lab as a nasal spray in order to minimize the risk of COVID-19 infection. We will examine the antiviral, hydroxychoroquine, overcoming its side effects by delivering low doses directly to the site of action. We will also deliver Mannin Research’s proprietary Tie-2 inhibitor, which has the potential to decrease ARDS, an often deadly complication of COVID-19 infection. This novel delivery system will provide options in the absence of a vaccine, mitigating the effect of the potentially deadly but expected second wave of the virus.

Develop a web based geospatial artificial intelligence framework to track, visualize, analyze, model, and predict infectious disease spread in real-time.

As location is an integral part of both population and individual health, there is an emerging role for geospatial artificial intelligence (GeoAI) technology in health and healthcare. Novel infectious diseases such as COVID-19 are associated with population density, environmental factors, and interactions between humans and wildlife. GeoAI technology can be used to collect and analyze large amounts of spatial data, such as individual-level epidemiological data, social media, human mobility, transportation, mobile phone data, and vulnerable populations. We will develop a Web based GeoAI framework to track, visualize, analyze, model, and predict infectious disease spread in real-time. The framework will analyze and simulate the transmission dynamics of the COVID-19 outbreak to predict trends in the demographic characteristics and the dynamics of the viral spread. Our Web based GeoAI framework will help Canadians understand how epidemics such as COVID-19 spread, what activities put people at risk, and where the next coronavirus hotspots are likely to be in Canada.

A decision support tool for promoting new business models of cultural organisations in the context of COVID-19 crisis

The COVID-19 crisis has stimulated the need for digital transformation among organizations in order to adapt their business models and practices to survive from the pandemic. Data-driven solutions would emerge as the key of success by supporting cultural organizations to launch new products / services, developing marketing strategies, and improving customer experience.

Our research project aims at proposing an approach for the design and implementation of a decision support tool for cultural organizations with the focus on dashboards supporting data-driven visualization and decisions. The proposed decision support tool is strongly believed to catch up with trends in customers’ preferences and behaviors. As the dashboards and interactive reports are integrated and analyzed from the diverse sources, cultural organizations can rely on the proposed decision support tool to develop new product or service offerings, improve marketing strategies, and gain competitive advantages.

Mechanism of CoVID-19 induced hyperinflammation

This Mitacs-NSERC COVID-19 joint initiative is to investigate the mechanism of COVID-19 inducing hyperinflammation and cytokine storm. COVID-19 infected cells cause injury that triggers immune cells to release inflammatory cytokines. The partnership with Encyt Technologies Inc. and PI will use established immune macrophage cell lines to identify the molecular mechanism of hyperinflammation induced by COVID-19 ACE2/Ang-(1-7)/Mas GPCR platform in triggering the processes associated with this cytokine storm. We have also identified that the prodrug, oseltamivir phosphate (OP), is active against mammalian neuraminidase-1 (Neu-1), which we think may have relevance as a potential anti-COVID-19 drug. Neu-1 has been reported by us to control the receptors on immune cells involved in this cytokine production. The potential outcomes will provide valuable knowledge and scientific evidence to treat patients infected with the COVID-19 virus in exhibiting signs and symptoms of impending respiratory failure.

Assessing the environmental impact of a novel solid-wall containment salmon aquaculture project

The intern will conduct a bio-physical audit of Agrimarines new salmon farming technology in China
and British Columbia. By collecting data about the farming operations, he will be able to account for
all the materials and energy used to build and run the farms. This includes things like building
materials, feed and amount of energy needed to run the farm day-to-day. This inventory will then be
used to build a model, called life cycle assessment, which can assess the average environmental
impacts associated with producing one tonne of salmon. The model will also be able to identify those
parts of the farming operation which contribute the most to environmental impact so that the
owner/operators can take steps to improve those parts of the system. By reducing these impacts, the
system can be made more sustainable. In addition parts of the system that are running inefficiently can…

Artificial Intelligence-based COVID-19 Radiology Image Analytics and Beyond

The excessive daily requirement for COVID-19 tests has put the healthcare providers in an overwhelming circumstance, especially in rural communities, with a limited number of resources. Moreover, the existing COVID-19 screening technique is time-consuming and expensive, which can be a luxury for many communities. Thus, in this research project, in collaboration with the TBRHRI, we press the necessity of an automated AI-aided solution for efficient and faster COVID-19 diagnostic. The main challenges during this pandemic time undertaken by this project are 1) facilitate the COVID-19 screening process by employing AI-based automated techniques, and 2) deploy the AI module in a web or mobile application by ensuring data privacy. This research project can benefit the TBRHRI to deal with uncertainties and excessive time-delay in terms of the COVID-19 screening process by utilizing artificial intelligence with automatic radiology image analysis to detect COVID-19.

Autonomous Stair-Climbing Domestic Service Robot

The main goal of this project is to develop a more advanced version of the Robotic Stairclimbing Assistant (ROSA), a stair-climbing domestic service robot developed by Quantum Robotic Systems. ROSA can carry heavier household items (e.g., laundry baskets, bins, etc.) between rooms and up stairs. ROSA is meant to help seniors, people with compromised mobility, and isolated individuals cut off from caregivers during the COVID-19 crisis. The research conducted in this project will enable ROSA to use sensors and control software to navigate automatically along paths in your home that may include staircases. For example, starting point “A” could be a main-floor laundry room while ending point “B” could be an upstairs bedroom. The result will be a highly capable product that is unlike any other household robot currently available.

Maximizing Intrinsic Learning in an App-Based Approach to Language Learning

This research is focused on optimizing the language learning that occurs when students are allowed to practice English by conversing with native English speakers via a smartphone app, specifically Goji. Learning is best when the student maximizes the density of their practice, returning to practice often. This research will focus on the characteristics of the native English speaking “mentors” such as their personality, intelligence, and even physical appearance. We will assess the extent to which various characteristics predict how often a student chooses to practice and, through practice, the success level they achieve.
Our findings will be useful in terms of informing the mentor characteristics most relevant to student success. This will allow a more informed hiring process and, ultimately, a better learning experience for students.

3-D Nanoscale Imaging of Coronavirus Analogues at Various Stages of Cell Infection

In the project, we will use an advanced microscope instrument, called a focused ion beam, to capture 3-D datasets of a coronavirus analogue and SARS-CoV-2 infecting cells to understand its biomechanical relationship at the cellular level. The intern will work on sample preparation, imaging of infection and turning those images into a computerized model to gain insights into the infection mechanism.

High yield micro-algal cultures

Micro-algae, which are being used to derive biofuels from, are typically grown in large volumes of water in systems which either expose the algae to, or protect it from, the natural environment. There are two key problems associated with large-scale commercial biofuel production: the identification of high yield and high lipid producing algal species, and maintaining the optimal growing conditions at a commercial scale. The goal of this research is to identify algal cultures which can attain both high yield and lipid production, as well as an increased resistance to invasion and fouling.

The project will deliver an instrument to perfor m SARS CoV 2 vaccine and viral therapy development at McMaster.

Next-Generation Precision Medicine Solutions – Diagnostics

As personalized medicine approaches aim to tailor treatments to individuals, improvements are needed in the detection of existing biomarkers and genomic, epigenomic, and proteomic changes that occur during disease development. This would have potential impact on medication selection and targeted therapy, reduce adverse effects, improve cost effectiveness, and shift the goal of medicine from reactive to preventative clinical decision making1. Liquid biopsies for cancer, in particular, have recently provided the advantage of early and easy screening but their use in replacing traditional methods of diagnosis needs to be validated before widespread adoption. The development of microfluidic approaches has greatly improved the sensitivity and specificity of single cell detection for many disease diagnoses. However, standardization and quality assurance need to be implemented to assure that assay performance is reproducible and robust. Within this proposal we are partnering with Cellular Analytics, a Toronto-based start-up company with a proprietary microfluidic platform (CytoFindTM) that detects protein expression on single cells. This technology will be used to develop and validate CytoFind as a diagnostic for two types of cancer and malignant pleural mesothelioma with the aim of improving clinical decision making and patient outcomes.
