IEEE Winnipeg Young Professionals

In this joint event hosted by IEEE YP Winnipeg and UMIEEE, recent graduates will be invited to participate in a panel discussion to learn about their industrial experiences and anything else that the audience would like to ask! This will be available both in-person on the University of Manitoba campus, as well as virtually via Zoom- please register to secure your attendance for either mode. Date: 27 Sep 2023 Time: 04:00 PM to 05:00 PM All times are (UTC-06:00) Central Time (US & Canada) The in-person portion will be hosted on the University of Manitoba campus in EITC room E2-165. The virtual portion will be hosted on Zoom as follows: Link: https://lakeheadu.zoom.us/j/93208535669?pwd=cjVweHpaa21xS0dYTnNGMG8vTXZBdz09 Meeting ID: 932 0853 5669 Passcode: 498086 Event recording is available on this link

Monochromatic light scattering can be used as a label-free, non-invasive biological cell detection and analysis method. Scattered light diffraction images can be used to extract information about the density, size, shape, as well as internal organelles of the cell. One cell death pathway is apoptosis and its study in a cell’s response to stress or disease such as cancer is important. Mitochondria play a key role in activating apoptosis and the phenomena of aggregation of mitochondria has been linked to apoptosis (X. Su, Y. Qiu, L. Marquez-Curtis, M. Gupta, C. E. Capjack, W. Rozmus, A. Janowska-Wieczorek, and Y. Y. Tsui, “Label-free and noninvasive optical detection of the distribution of nanometer-size mitochondria in single cells,” Journal of biomedical optics, 16(6), 2011). In this paper we show that forward angle scattered light patterns can be used to infer changes in interior cell components like mitochondria and nucleus, as well as cell size. We employ a Multi-shell MIE theory approach, which provides an analytical solution for light scattering from a heterogeneous shelled sphere interacting with a planar electromagnetic wave. We use this to model a biological cell, where changes in the cell's properties, such as changes to cytoplasm or nucleoplasm density, the size of the cell or its nucleus, or the distribution of internal organelles, are reflected in changes in the refractive index of the shells. The developed model is used to simulate the effect of these variations on a Chinese hamster ovary (CHO) cell. The results are related to light scattering measurements obtained using a lens-less microfluidics-based cytometry device (A. Fazelkhah, S. Afshar, N. Durham, M. Butler, E. Salimi, G. Bridges, and D. Thomson, “Parallel single-cell optical transit dielectrophoresis cytometer.” Electrophoresis, 41, 720-728, 2020). In the simulations, we consider scenarios where the mitochondria are concentrated within various regions of the cytoplasm and demonstrate it is possible to discern these changes using the forward scattering patterns.

Hello Winnipeg IEEE members and Capstone award candidates, Join us for Networking and a BBQ as we hand out IEEE awards to Capstone teams. This event was hosted by Winnipeg YP in St. Vital Park- more details on the exact location will be shared closer to the date. The event is free for IEEE members and Capstone award candidates, or $5 for everyone else to cover food costs. Date: 03 Aug 2023 Time: 06:00 PM to 09:00 PM All times are (UTC-06:00) Central Time (US & Canada) Registration is required. Post Event Thanks to all people who participated in the event.
