Diabetes and peripheral arterial disease affect hundreds of millions of people worldwide. Patients with these conditions frequently develop chronic wounds on the lower limbs that lead to amputation, with a 5-year mortality rate as high as 77%. Macrophages, the primary cell of the innate immune system, are critical regulators of angiogenesis and wound healing. Their dysfunction is strongly implicated in arterial dysfunction, limb ischemia, and poorly healing chronic wounds. The goal of the Biomaterials and Regenerative Medicine Laboratory at Drexel University is to understand the mechanisms by which macrophages orchestrate successful angiogenesis and tissue regeneration and to develop novel biomaterial strategies that apply these principles to pathological situations, in order to ultimately prevent limb amputation. This talk will focus on the effects of temporal changes in macrophage phenotype on angiogenesis, the design of biomaterials and drug delivery systems to modulate macrophage phenotype for enhanced angiogenesis, and the development of macrophage phenotype-related biomarkers to assist in clinical decision making for a personalized medicine approach to wound care.

Professor. Matthias HeinemannThe principles governing cellular metabolic operation are poorly understood. Because diverse organisms show similar metabolic flux patterns, we hypothesized that a fundamental thermodynamic constraint might shape cellular metabolism. Here, we develop a constraint-based model for Saccharomyces cerevisiae with a comprehensive description of biochemical thermodynamics including a Gibbs energy balance. Non-linear regression analyses of quantitative metabolome and physiology data reveal the existence of an upper rate limit for cellular Gibbs energy dissipation. By applying this limit in flux balance analyses with growth maximization as the objective function, our model correctly predicts the physiology and intracellular metabolic fluxes for different glucose uptake rates as well as the maximal growth rate. We find that cells arrange their intracellular metabolic fluxes in such a way that, with increasing glucose uptake rates, they can accomplish optimal growth rates but stay below the critical rate limit on Gibbs energy dissipation. Once all possibilities for intracellular flux redistribution are exhausted, cells reach their maximal growth rate. This principle also holds for Escherichia coli and different carbon sources. Our work proposes that metabolic reaction stoichiometry, a limit on the cellular Gibbs energy dissipation rate, and the objective of growth maximization shape metabolism across organisms and conditions.

Associate Professor Vikramaditya Yadav
The Biofoundry, Department of Chemical and Biological Engineering
University of British Columbia
Associate Professor Vikramaditya YadavHosted by Prof. Krishna Mahadevan
The principal theme of Prof. Yadav’s research is the utilization of metabolic & enzyme engineering to investigate and customize novel biosynthetic enzymes that can convert biomass-derived feedstocks into value-added chemicals. His group also extends the principles of metabolic engineering to the design and development of unique bioremediation strategies to rehabilitate the water quality in and around industrial zones and develop new mining biotechnologies. In addition to green engineering, his research group also pursues medical biotechnology research, and focuses on bioengineering for assay development, lead generation and product development.
The seminar will provide a broad overview of the research and commercialization efforts that are afoot in his laboratory at UBC. In particular, the talk will cover some of his group’s recent successes in elucidating and using a novel plant metabolic pathway for the synthesis of value-added chemicals, the development of a biosensor for screening insect repellants, bioremediation of oil sands tailings ponds and the fabrication of biohybrid materials for harvesting solar energy.

Mining biotechnology provides sustainable alternatives to traditional mining methods for extracting value from low grade ores and wastes. Moreover, biotechnology can be harnessed to treat (bio)hydrometallurgical and mine waters and decrease the environmental footprint of mining operations. This presentation will give an overview of CSIRO activities in bioleaching and bio-oxidation of low-grade ores, mine wastes and post-consumer wastes such as batteries and electronic wastes. Moreover, studies on removing inorganic and organic contaminants and recovering value from metallurgical effluents will be discussed.

There has been a race to build active learning spaces, and particularly spaces that are heavily technology enabled. At the University of Toronto there are several major projects of this nature underway or recently completed, including the new Myhal building and the Transforming the Instructional Landscape (TIL) project. There is a general sense that classroom environments of this nature support active learning pedagogies, but to what degree is this supported by the literature and what aspects of the design are important? In this talk Prof. McCahan will explore the literature that exists on active learning spaces and the design concepts that underpin this trend in classroom construction. She will also discuss her current research in this area and the gaps in our understanding that need to be investigated to ensure that classrooms enable, rather than hinder, faculty who are implementing high impact teaching practices.

The seminar will focus on leading edge research in China on ventilation and energy conservation for industrial processing plants. Team members and research platforms of national key laboratories will be discussed. An outline will be presented of the major research work at Xi’an University in the industrial ventilation field and how the research has been applied to engineering applications for specific industrial applications. An extensive compilation of Chinese standards as they apply to industrial ventilation and energy efficiencies will be discussed. A scientific review will include research projects currently underway at Xi’an University which includes the scope of independent research projects, domestic collaboration, and also a new thrust in international collaboration with the global scientific research community. Two examples of innovative research in the industrial ventilation field will be presented. The first example will be the use of scale model experiments to optimize the design of local ventilation systems. Air pollution and energy consumption in industrial plants are serious challenges to sustainable development in China’s economy.

In the past three decades, there has been a concerted effort in the chemical, specialty chemical, agrochemical, pharmaceutical, and petroleum industry to design cost-advantaged, inherently safer, sustainable, and environmentally-friendly processes. Catalysis plays a crucial role in improving process efficiencies and process intensification leading to increased atom utilization, reduced by-product formation, cheaper process, and lower capital investment. Also, there is an increasing interest in using renewably-sourced feedstocks for the production of fuels, chemicals, and advanced materials due to rising petroleum prices, limited availability of petroleum resources, and increasing consumer consciousness about sustainable processes.
Although catalysis is a major tour-de-force in driving this efficacious and green chemistry revolution, the role of reaction engineering, reactor design, process design, and operating conditions cannot be underestimated. Some of the fundamental concepts of catalysis will be discussed and linked to a number of chemical processes of industrial relevance. The role of science and engineering in industrial catalysis will be illustrated with particular emphasis on catalyst attributes and catalyst development associated with industrial processes. Case studies will include hydrogenation reactions using supported base metal and precious metal catalysts and solid acid catalyzed dehydration reaction.
