LLE: Revolutionizing Drug Delivery Technology: The Power of AI and Automation (Christine Allen, University of Toronto) @ WB116
Mar 6 @ 11:00 am – 12:00 pm

Christine Allen, University of Toronto

Host: Prof. Milica Radisic

 

The formulation of therapeutic agents in advanced drug delivery systems such as nanoparticles and microparticles can significantly improve their safety and efficacy. However, the design and development of advanced formulations remains expensive, labour-intensive and time consuming with a heavy reliance on the expertise of the formulation development team and composition of formulations that have been approved to date. In the design of these systems, there are a plethora of parameters that must be considered in relation to the drug, material(s) or excipient(s) as well as processing variables. Experimental evaluation of every combination is intractable and at this time it is not possible to predict the performance of specific formulations a priori. As a result, it is likely that some of the formulation candidates that have moved forward to clinical development are not optimal but rather the best that could be achieved with the time and resources available.

Machine learning (ML) has led to significant advances in various fields, such as drug discovery and materials science. In recent years, we have explored integration of ML to discern the relationships between composition, property and performance with a goal towards fast-tracking innovative drug formulation development.  In this work, we have identified a lack of robust datasets in the published literature to apply data-driven methods. This has led us to consider strategies such as experimental automation, and more recently to the concept of a materials acceleration platform (MAP), or self-driving laboratory (SDL), that combines automated experimentation with ML-guided experiment planning for the design of advanced drug delivery systems. The integration of such technological advancements in the pharmaceutical sciences has the potential to fast-track preclinical research, improve efficiency in drug development pipelines and thus improve patient access to effective medicines.

LLE: Efficient Assessment: Getting More Value With Less Effort (Peter Ostafichuk, University of British Columbia) @ WB116
Mar 20 @ 11:00 am – 12:00 pm

Peter Ostafichuk, University of British Columbia

Host: Prof. Jennifer Farmer

Assessment is widely viewed as an integral part of teaching and learning. More than a means to benchmark student performance, effective assessment is a powerful learning activity. In addition, well-constructed assessments allow students to monitor their learning progress and adapt; provide instructors with insights on student development and teaching effectiveness; and help units to evaluate program outcomes as part of continual improvement or accreditation. At the same time, trying to deliver effective assessments in large (and growing) classes with fixed (and often diminishing) resources can be challenging. This talk will explore assessment approaches that address the multiple aforementioned goals while reducing time and resources requirements and allowing scalability to classes of almost any size.  Grounded in fundamental principles of effective assessment, multiple evidence-based examples will be featured, including collaborative in-class testing techniques; comparative evaluation and multi-stage peer assessment; and meaningful auto-graded questions suitable for exams and online homework.

LLE: Next Generation Membranes through Polymer Self-Assembly (Ayse Asatekin, Tufts University) @ WB116
Apr 3 @ 11:00 am – 12:00 pm

Ayse Asatekin, Tufts University

Host: Prof. Jay Werber

Membranes offer a highly energy-efficient, simple to operate, scalable and portable separation method for many applications, from water treatment to oil and gas processing to pharmaceutical manufacturing. Yet, their broader use is often limited by insufficient selectivity and/or fouling with complex feeds. There are no commercial membranes that can separate small molecules of similar size in the liquid phase based on their chemical properties. We aim to develop new synthetic polymer membranes that accomplish this by self-assemble and create structures that mimic key features of biological pores like ion channels and porins: Constricted pores <5 nm in diameter that confine permeation, lined with functional groups that interact with the target during passage. Our first approach utilized the self-assembly of zwitterionic amphiphilic copolymers (ZACs), synthesized from a hydrophobic and a zwitterionic monomer. When ZACs are coated onto a support to form a thin film composite (TFC) membrane, self-assembled zwitterionic domains act as a network of nanochannels for water permeation. Our first ZAC-based thin film composite (TFC) membranes were size-selective with an effective pore size of ~1.3-1.5 nm. These membranes are exceptionally fouling resistant. We then developed cross-linkable ZACs (X-ZACs), which enabled us to access smaller effective pore sizes, down to ~0.9 nm, where ion separations are possible. Our membranes with the smallest pore sizes exhibited unprecedented selectivity between equally charged anions, including the highest Cl/F selectivity in the literature. This selectivity arises from zwitterion-ion interactions, which affect both ion partitioning and ion diffusivity, further emphasized through nanoconfinement. This opens the door to novel membranes with novel selectivity between molecules and ions of similar size and charge, mediated through channel-solute interactions. More recently, we have been exploring new avenues to prepare membranes the self-assembled nanopores and fouling resistance of ZAC-based membranes, but expand the range of separations accessible. We have developed amphiphilic polyampholytes (APAs), where hydrophobic, anionic, and cationic monomers form a random/statistical terpolymer that is insoluble in water. This approach allows access to a very broad array of functional groups lining the effective nanopores of these membranes, opening the door for complex separations. Alternatively, we have formed amphiphilic polyelectrolyte complex (APEC) membranes by coating consecutive layers of two amphiphilic polyelectrolytes (i.e. water-insoluble copolymers combining a hydrophobic monomer with either an anionic or a cationic monomer). Interestingly, these bilayer membranes exhibit very small effective pore sizes as well as higher permeances, implying selectivity arises from the formation of polyelectrolyte complexes at a thin interface between these layers. These approaches demonstrate a versatile and highly customizable approach for developing novel high-performance membranes.

About LIT: Life Ignition Tools

In the age of convenience, information overload, and endless exposure to stimuli, it’s easy to trudge through the motions of life, pressured, distracted, and seeking instant gratification. When this way of living becomes the norm, it can immobilize us, making it feel impossible to reclaim control of our lives with intention and enthusiasm.

In LIT (William Morrow; April 9, 2024), Harvard Medical School professor, Mass General Brigham and MIT researcher, and renowned bioinspirationalist Jeff Karp, PhD, teaches us to harness the vital wisdom and power of nature to place us into a lit state. Lit is a life magnifier, a heightened state of awareness that drives curiosity, connection, and energy. In short: being lit takes us off autopilot and helps us stay alert, present, and fully engaged.

Diagnosed with learning differences and ADHD at a young age, Karp persisted through nearly insurmountable struggles. After discovering that he could think about thinking at age seven, he became his own science experiment, tapping into the lit state through trial and error to achieve hyper-awareness and explore his curiosity, creativity, and connection to nature. Decades later, as a biotech innovator, husband, and father, lit continues to encourage opportunities for innovation in his professional and personal lives.

He has honed those methods into a diverse toolkit that he calls Life Ignition Tools (LIT), which help us:

  • Break out of habitual thinking to discover our own imaginative power.
  • Stimulate creativity and excitement at work.
  • Integrate our spiritual and personal lives to repair and deepen our relationships.
  • Navigate multiple streams of sensory input and manage information overload.

Lit has inspired Dr. Karp’s innovative medical discoveries such as surgical glue inspired by slugs, a diagnostic for cancer based on the tentacles of jellyfish, and surgical staples based on the quills of a porcupine – but you don’t have to be a scientist to live lit. Anyone can use these principles to redirect their lives with energy, focus, creativity, and motivation to create the lives they truly want to lead.

Research Seminar: Navigating Sustainability through Energy, Water, and Medical Innovations @ WB215; Teams
May 3 @ 10:00 am – 11:00 am

Abstract

Sustainability has many facets and, in this presentation, I will share my recent research endeavors aimed at advancing sustainability in the realms of energy, water, and medicine. The first part of my talk delves into electrochemical transport phenomena in energy storage systems, with a focus on Li plating and dendritic growth on graphite/Li-metal anode, which are the leading causes of degradation and catastrophic failure for batteries under fast charging conditions. Deep understanding of these phenomena would facilitate the design of strategies to reduce, or completely suppress, the onset of lithium plating on the graphite anode, and the instabilities characterizing electrodeposition on the lithium metal anode.

In the second part of my talk, I will present my recent work on the efficient estimation of evapotranspiration for smart agriculture. This includes advancements that accelerate computational time by two orders of magnitude compared to the current standard approach. Finally, I will discuss two biomedical applications: blood transfusion and hypertonic treatment of acute respiratory distress syndrome (ARDS). These efforts contribute to sustainable energy conversion and storage, sustainable agricultural practices, and sustainable blood management, steering us towards a more sustainable future.

Seminar: “Use of Big Data in Search of Novel Treatments for Pulmonary Fibrosis” (Dr. Gregory Downey, University of Colorado) @ Red Seminar Room, Donnelly Centre
May 27 @ 2:00 pm – 3:00 pm

Idiopathic Pulmonary Fibrosis (IPF) is a chronic, progressive, and often fatal disorder for which there are two FDA-approved anti-fibrotic drugs, nintedanib, and pirfenidone. While these drugs slow the rate of decline in lung function, responses are variable and side effects are common. Using an in-silico data-driven approach, we identified a strong inverse connection between the transcriptomic perturbations in IPF disease and those induced by saracatinib, a selective Src kinase inhibitor, originally developed for oncological indications. Accordingly, we investigated the anti-fibrotic efficacy of saracatinib relative to nintedanib and pirfenidone in three preclinical models: (i) in vitro in normal human lung fibroblasts (NHLFs); (ii) in vivo in bleomycin and recombinant adenovirus transforming growth factor-beta (Ad-TGF-β) murine models of pulmonary fibrosis; and (iii) ex vivo in mice and human precision cut lung slices from these two murine models as well as from patients with IPF and healthy donors. In each model, the effectiveness of saracatinib in blocking fibrogenic responses was equal or superior to nintedanib and pirfenidone. Transcriptomic analyses of TGF-β-stimulated NHLFs identified specific gene sets associated with fibrosis including epithelial mesenchymal transition (EMT), TGF-β, and WNT signaling that was uniquely altered by saracatinib. Transcriptomic analysis of whole lung extracts from the two animal models of pulmonary fibrosis revealed that saracatinib reverted many fibrogenic pathways including EMT, immune responses, and extracellular matrix organization. Amelioration of fibrosis and inflammatory cascades in human precision cut lung slices confirmed the potential therapeutic efficacy of saracatinib in human lung fibrosis. These studies identify novel Src-dependent fibrogenic pathways and support the study of the therapeutic effectiveness of saracatinib in IPF treatment.

Ph.D Candidate Seminar: An Investigation of SC05: a Chloroform and Dichloromethane Degrading Microbial Community for Bioremediation (Olivia Bulka) @ WB215; Teams
Jul 5 @ 9:00 am – 10:00 am

Abstract

Bioaugmentation has emerged as an effective way to remediate groundwater of anthropogenic contaminants, such as chloroform (CF) and dichloromethane (DCM). The Dehalobacter genus can anaerobically respire many of these chlorinated compounds using reductive dehalogenases, often as part of a heterogenous microbial community. One such community is SC05, which dechlorinates CF completely to carbon dioxide and hydrogen. Despite its effective use at contaminated sites, prior to this work SC05 remained unstudied in terms of taxonomy and broader metabolism, without identification of the active DCM degrader(s?). This thesis seeks to ascertain key microbes in the culture and their metabolic mechanisms using experimental, metagenomic, and metabolic modelling approaches.

A unique characteristic of “self-feeding” is first established in SC05, wherein electron equivalents produced from DCM mineralization are harnessed for CF dechlorination. An SC05 subculture continually dechlorinated CF for over 1400 days with no exogenous electron donor. Dehalobacter was the only bacterial genus that grew in either the CF dechlorination or DCM mineralization phase, implicating it as a key mediator of both CF and DCM degradation. Dehalobacter expressed a single reductive dehalogenase that dechlorinates CF to DCM but has no activity on DCM, as well as the mec cassette—core proteins for DCM degradation. These two modules were within 10 kb in a single genomic neighbourhood.

Two unique Dehalobacter genomes were ultimately assembled, each of which encoded the acd- mec neighbourhood. When assessed pangenomically, this region was designated as a mobile genetic element resulting from horizontal gene transfer between Dehalobacter strains. Each strain could employ this shared genetic cargo to dechlorinate CF and mineralize DCM, with differing dynamics dependant on culture conditions. Genome-scale metabolic models of each strain were curated to predict and compare metabolism during each remediation step.

Overall, this work elucidates some of the former mysteries of SC05, informing considerations for field application such as electron donor demand. It also highlights the importance of hydrogen cycling and microbial syntrophy in anaerobic DCM degradation. Fundamentally, it expands the typical assumptions of the metabolic rigidity of Dehalobacter genus and posits mechanisms of evolution and horizontal gene transfer as it pertains to adaptation of microbial communities to anthropogenic chemicals.

Seminar: “Multiple Micronutrient Fortification of Foods – An Update” – Professor Marthi Venkatesh-Mannar @ WB407; Teams
Jul 9 @ 2:00 pm – 3:30 pm

Abstract: Food fortification programs aim to provide meaningful amounts of micronutrients (e.g., 30%-50% of the daily adult requirements) at the average consumption level of one or more food vehicles. Foods that can be fortified include wheat and wheat products, maize, rice, milk and milk products, cooking oils, salt, sugar, and condiments. New vehicles widely and regularly consumed in certain regions, like bouillon cubes, flavouring sauces, or tea, are also gaining new attention. Micronutrient premixes for home fortification are also being promoted. Depending on the food processing methods, adding the micronutrients can be facilitated using different approaches to maximize nutrient retention. These include dry mixing, dissolution in water/oil, micronization, spraying, adhesion, coating, extrusion, micro-encapsulation, and dry mixing.

Cost, bioavailability, sensory acceptability, and stability (during storage and cooking) are the critical criteria for determining the best match between the nutrient and food vehicle. When added to food or beverage carriers, specific vitamins and minerals could interact with each other and the food, reducing their bioavailability and organoleptic quality. The development of appropriate technology to optimize the effectiveness of fortification needs special attention.

Better refining procedures and packaging have significantly improved the stability of iodine compounds in salt and vitamin A in cooking oils. The structure of the compounds can also be modified to improve absorption. In the case of iron, stabilizers, chelating agents, and absorption enhancers could be added along with the fortificant to retain it in an absorbable form or improve absorption. The extrusion and micro-encapsulation of micronutrients can ensure nutrient stability while ensuring breakdown and absorption in the gut. Technological improvements in the analytical methods for testing fortified foods have been developed specifically to monitor nutrient retention from production to consumption.
