The BME Seminar Series features presentations surrounding the field of Biomedical Engineering.
Next Upcoming Seminar:
Date: 2018 November 28
Time: Noon - 1PM
Location: 1-075 RTF
Presentation Topic: Targeting the Senescence-Associated Secretory Phenotype: The profound effects of natural molecules on inflammation produced by senescent cells
Presenter: Kevin Perrott, PhD Student, Dept. of Biomedical Engineering
Natural compounds from fruits and vegetables such apigenin (4',5,7,-trihydroxyflavone) have been shown to have pleotropic effects able to attenuate the inflammation associated with many chronic diseases of aging. Senescent cells-stressed cells that accumulate with age in mammals-display a pro-inflammatory senescence-associated secretory phenotype (SASP) that can drive or exacerbate several age-related pathologies, including cancer. This work examines the effects and mechanisms of apigenin and other natural compounds on senescence and the SASP looking at the role these natural compounds could play in reducing tumorigenesis.
All are welcome!
The BME Seminar Series features presentations by current graduate students as part of the BME 600A/B courses (Fall/Winter terms). Each of the seminars offers a glimpse into biomedical research taking place at our university.
Details about the next series will be posted soon!
Title: Improving Globus Pallidus segmentation using MPRAGE phase
Speaker: Nashwan Naji
Date: Wednesday, Mar 20, 2019
Time: Noon to 1:00 PM
Venue: ECHA L1-220
Segmentation of brain structures facilitates many neuroscience studies and is commonly performed on three-dimensional volumes obtained using Magnetic Resonance Imaging (MRI). Magnetization-Prepared Rapid Gradient-Echo (MPRAGE) is an MRI technique that provides sufficient contrast between different tissues, making segmentation relatively hassle free. However, some structures in the Deep Grey Matter (DGM) of the brain have weak contrast relative to surrounding tissues, which can make segmenting them challenging. A particularly problematic structure is the Globus Pallidus (GP): a crucial nucleus in the basal ganglia that is poorly segmented based on MPRAGE contrast alone. Recently, several studies have shown that the DGM segmentation, including GP, can be improved by jointly processing contrasts of MPRAGE and Quantitative Susceptibility Mapping (QSM): an iron-sensitive imaging technique. This method however generates QSM contrast from an additional Gradient-Echo (GRE) acquisition. In this talk, I will present one possible way to improve GP segmentation using MPRAGE phase itself without the need for additional data. QSM can be produced from the phase part of the MPRAGE data and then employed to improve GP segmentation. This way, the need for additional GRE scan is avoided, which saves time and minimizes possible motion and registration related errors.
All are welcome!

RTF Table Tennis Tourney April 2018!
Want to play table tennis (ping-pong)?
Want to meet other people from RTF/Imaging Research?
Why not kill 2 birds with 1 stone?
If you're interested, e-mail Prayash and Kevin (or let them know in person)
Update 4 April 2018:
The paddles are here, the table is set, and the nets are waiting!
Tentatively, we are planning the tournament day during the week of April 23-27, but please use our Table Tennis Tourney Doodle Poll to indicate which day works best for you. The tourney bracket will include everyone who signs up.
We will also have a practice session some time prior to the tournament. We will use this to go over the rules, wipe some of the rust off, and make sure everyone is on the same page! Everyone who is interested can fill out the Practice Day Doodle Poll.
Keep a look out for an e-mail next Friday (April 13) confirming the date and time!
Please feel free to forward this to anyone in BME who may not have received it.
