Encapsulation of cells in a biocompatible hydrogel to relieve pain following intervertebral disc degeneration

Intravertebral disc degeneration is a common debilitating condition for which there is no cure and leads to back pain and disability. In order to provide sustained pain relief, research is investigating the use of local cell transplantation into the disc. However, many current cell delivery strategies suffer from low cell retention and survival following injection into the tissue. To address this, our lab has developed an injectable, biocompatible hydrogel (HAMC) that cells can be mixed into and then injected through a small-gauge needle. We have previously demonstrated efficacy of this system in models of spinal cord injury, stroke, and retinal degeneration. First, we will combine cells with HAMC on the benchtop and test the ability to load cells into the syringe and cell survival following injection, and the optimal HAMC formulation will be determined.

Design Optimization of Binary Phase Pupil Filters

Today, optical imaging technologies are used extensively for a wide range of advanced medical imaging, diagnostics, and therapeutics applications. While current state-of-the-art pupil engineering has examined diverse mask types to enhance these imaging capabilities, binary phase masks (BPMs) have been suggested as the superior filter for achieving enhanced axial and transverse beam properties, offering the best balance between depth-of-focus (DoF) and resolution. In collaboration with the Biomedical Optics and Instrumentation Laboratory at Yonsei University (Korea) and the Structural and Multidisciplinary Systems Design Lab at Queen’s University (Canada), this research will apply topology optimization for binary phase mask design, utilizing the unique expertise offered by both institutes to create novel filter concepts.

One Nation, One Face: A Critical Exploration of Sociality and Cultural Oppression in the South Korean Plastic Surgery Phenomenon

Combining semi-structured interviews of plastic surgery doctors and individuals interested in plastic surgery as well as content analyses of magazine and newspaper articles on plastic surgery, this research aims to inductively examine the intersubjective production of meaning among South Korean individuals in the context of the nation’s massive plastic surgery trend. To this end, this research will flesh out the values, norms, and logics invested in plastic surgery, the actors and processes that shape and maintain these standards, and their implications for social life. Expected results point to how powerful social norms and media representations dictate standards of beauty and worth in ways that oppress individuals. Furthermore, the growing commonness and capabilities of plastic surgery embody cultural logics that transform how the self, others, and relationships are interpreted altogether in broader social life. This ultimately reorganizes the social bases, structures, and contexts of interaction around materialistic pursuits and conforming one’s identity.

Apply Deep Neural Network to Detect Malignant Lung Nodules in CT Scans

Lung cancer has a poor prognosis and a high incidence in low resource settings. Early detection of malignant nodules can enable prompt intervention and improve treatment outcomes. Despite the recognized benefits of early nodule detection, it is clinically and computational challenging. Convolutional neural network (CNN) is a type of machine learning that has been applied to analyzing visual images, and has received increasing interest in facilitating image recognition in medical field. The study will apply CNN to pre-labeled low dosage computed tomography (CT) scans collected in Zhongshan Hospital (Shanghai) to differentiate malignant nodules from benign nodules. A training set will be used to train the model first, followed by fine-tuning the model to increase the diagnosis accuracy and sensitivity. A set number of CT scans will be used as the test set to examine the accuracy rate.

Physiological signal based interface for a robotic system to support play in children with physical disabilities

Through play children develop sensory, motor, cognitive, communication and social skills. Children with physical disabilities, who have a limited access to play, may experience negative impacts on these aspects of development. Using robots to manipulate play objects can contribute to the children’s independence, social and cognitive development. The interface with which the children control the robot needs improvement. Haptic interfaces can provide the sense of touch during interaction with objects and toys. The eyes can provide information about the toys that a child might want to manipulate. The goal of this project is to integrate a haptic interface with eye tracking technology and other physiological signals (e.g. muscle, brain, or face gestures) to support play in children with physical disabilities. Results will yield to a clearer understanding of children’s visual behavior when playing and future direction for the development of robots to support play in children with physical disabilities.

Temperature and dosage dependence of biological damage induced by ultraviolet germicidal irradiation on pathogens and comparison with conventional chemical wipes

Healthcare acquired infections (HAIs) represent a common complication for hospitalized patients and can produce significant financial implications for the health care system. Unfortunately, mobile and handheld devices are recognized as a hub for bacteria and viruses that can cause these infections. To aid in a remedy for this, ultraviolet light is an emerging technology that is becoming increasingly popular for germicidal surface disinfection in healthcare. It has the advantages of being chemical-free, more reliable and faster than existing sanitization protocol, which involves the use of germicidal wipes. Though UV has been used for decades for water disinfection, due to its recent development in the surface disinfection space, there is a lack of scientific data or papers that thoroughly study its effectiveness.

Optimisation de la qualité des images et visualisation des tissus mous : mise au point de nouvelles approches en CBCT

L’imagerie cone beam CT (CBCT) prend une place de plus en plus importante dans l’exploration des structures osseuses du complexe dento-maxillo-facial. Cette modalité d’imagerie, moins irradiante que l’imagerie par tomodensitométrie conventionnelle (TDM), procure des images de qualité similaire, voire supérieure, à celle des images TDM. Toutefois, les rapports Signal/Bruit ne sont pas assez élevés, et les doses, bien qu’inférieures à celles en TDM, pourraient encore être diminuées. Un des objectifs de ce projet est donc d’optimiser la qualité des images tout en cherchant à réduire davantage la dose de radiation ionisante. Pour atteindre ce double objectif, nous proposons de mettre en oeuvre de nouveaux algorithmes de reconstruction/rétroprojection, notamment en faisant appel à des méthodes de reconstruction itératives.

Impact des changements climatiques sur l’écophysiologie et la biogéographie du nerprun bourdaine dans l’est du Canada

Une espèce est dite ‘envahissante’ lorsqu’elle est capable de s’établir de façon remarquable dans un nouveau milieu, hors de son aire d’occurrence naturelle. Le nerprun bourdaine (Rhmanus frangula) est une plante envahissante au Canada et aux États-Unis. Originaire de l’Europe et de l’Asie, cet arbuste occupé les forêts et les plantations du Québec et empêche la régénération et succession végétale. Ce projet de recherche vise identifier quelles sont les facteurs environnementaux et physiologique que facilitent l’envahissement et quelles sont les dommages que le nerprun cause chez les forêts québécoises. Le projet envisage aussi connaître les stratégies de reproduction de la plante, le processus de germination de ses graines et de compétition avec nos espèces indigènes. Ouranos est un consortium de recherche qui s’intéresse aux changements climatiques et ses impacts. TO BE CONT’D

Brazil’s Female Voice in International Relations: Bertha Lutz and the Founding of the United Nations in 1945

This project examines the work of Bertha Lutz, the only female delegate from Brazil and one of the four women to sign the United Nations Charter in 1945 at the San Francisco Conference. Eight women were present at San Francisco as official delegates from seven different countries, making significant contributions to the UN Charter. But these contributions still remain unexamined. Lutz was a key figure in the Pan-American feminist movement, spending twenty years as the leader of the Brazilian Federation for Women’s Progress, and representing Brazil in the international stage. Much of the work about Lutz is focused on her contributions to the feminist movement and not her role in politics. This project aims to highlight Lutz’s work in international diplomacy and discuss her role in the UN, with the objective of bringing to light the importance of female contributions to the UN.

Catalytic effect of nano-NiO particles in Pyrolysing of Biomass materials

Biomass materials have been a source of energy for years to now and their effective conversion into usable energy form is always under research to get improved results. Various techniques and systems have been developed to exploit different biomass materials so far and this research aims to study the effect of nano NiO particles as catalyst in pyrolysing of agro residues such as rice husk, saw dust, and groundnut shell, etc. The catalyst will be prepared and employed in different size to observe the effect of particle size in pyrolysis and the operating conditions of the test will also be varied to know their effect. Different approaches such as TGA, FTIR, and XRD will be used to characterize the precursors and nano-NiO particles. The experimental results will be correlated with theoretical and kinetic modeling to find the activation energy and conclude the results.

Sustainable production of cellulosic ethanol from pretreated sugarcane bagasse using ruminal fluids extracted from ruminating animals

Increase in global temperatures, over dependence and depletion of fossil fuels to fulfill the human needs have forced the mankind to produce sustainable bioenergy. Plant biomass which contains lignocellulose polymers constitutes the most abundant components on the earth’s surface. Naturally, enormous amounts of cellulose are digested by the cattle and this process of digestion is solely supported by microorganisms residing in its rumen. In our current project, we have considered sugarcane bagasse to produce cellulosic ethanol using ruminal fluids. Sugarcane bagasse is the waste obtained after sugar production which is currently being burned for energy or dumped in landfills. Initially, we have pretreated sugarcane bagasse using specific pretreatment methods. Pretreated sugarcane bagasse is further subjected to enzyme hydrolysis under standard and optimized fermentation methods using the ruminal fluid samples obtained from Brazilian cows. This ecofriendly and economically beneficial method of cellulosic ethanol production would reduce our dependence on fossil fuels.
