I?ve attached an abstract below. Please do attend and should you like to meet with Pierre after the talk (e.g. on Thursday or Friday this week) let me know and I will arrange a suitable time. Best Regards, Kaleem ------------------------------------------- Date/Time/Location: Wednesday, December 2nd, 4pm to 5pm, McConnell Engineering 437 Speaker: Dr. Pierre Jordaan Cardiovascular Safety Expert, Novartis Pharma, Switzerland. -------------------------------------------- Challenges in measuring Cardiac Function and dysfunction: A clinical perspective Nature has provided man with robust physiological systems to sustain life and ensure survival under adverse conditions. The cardiovascular system is such a system, with considerable redundancy to ensure a continuous blood circulation to the vital organs. Therefore, despite significant advances in medical research, the early identification of cardiotoxicity, which would allow early intervention, remains challenging. Echocardiography and magnetic imaging are the two cornerstones of measuring cardiac function directly. Neither is optimal ? technical issues including operator dependency causes considerable variability with echo?s (up to 12%), and accessibility, exposure to radiation and cost limit the routine use of MRI. Cardiotoxicity can be either reversible or transient (Type I), or permanent (Type 2). Often dysfunction starts as functional changes and as the disease progresses, structural damage follows. However, non-specific cytotoxic agents may cause permanent damage to the heart and other organs that may only manifest and be diagnosed late. Routine assessment for the early identification of cardiotoxicity in clinical research include circulatory biomarkers. Typically this includes the cardiac troponins (or CK/CK-MB) that measures myocardial cellular toxicity, and the natriuretic peptides, that reflect cardiac overload. More recently, disease-specific miRNA is being assessed, although it is still not clear if the miRNA elevation is pathology- or compound-specific or compound-agnostic, and whether they are epiphenomena or are actively involved in the pathologic process. What is clear that these circulatory biomarkers may occur transiently, and too early or too late blood sampling may not be diagnostic, despite the presence of structural disease. Cardiotoxicity is especially relevant in oncology: As patients with cancer survive longer, cardiotoxicity may manifest after a long time. Secondly, targeted cancer therapy may alter the very core of life-sustaining pathways both in cancer cells and in healthy tissue, including the heart. Earlier identification of cardiac dysfunction would potentially guide drug selection, trigger dose reduction, or alert the clinician to the need for preventative treatment, which has been effective in breast cancer, for example. -------------- next part -------------- An HTML attachment was scrubbed...

The talk is targeted for a general audience Changing magnetic fields in MRI: challenges and opportunities Magnetic fields are clearly necessary in Magnetic Resonance Imaging - it is right there in the name! The main magnetic field is very strong, the radio-frequency magnetic fields are very fast, and the gradient magnetic fields are somewhere in between. In this talk, we will talk about the effects, good and bad, of changing (in time) these magnetic fields. On the one hand, the presence of changing magnetic fields represents a particular challenge for implanted medical devices (think pacemaker). We will review the status of medical devices within the MR system environment, and look ahead to what is on the horizon. On the other hand, the ability to change the main magnetic field (say from 1.5 T to 1.7 T, then back again) during imaging allows some exciting opportunities. We will review a new method of MR called delta relaxation enhanced MRI ("dreMR") and the potential benefits associated with the technique. -------------- next part -------------- An HTML attachment was scrubbed...

She holds a Canada Research Chair in Early Detection of Alzheimer?s Disease. Her team uses multimodal neuroimaging (PET and MRI) to investigate brain changes associated with neurodegeneratives diseases. Dr. Villeneuve received a PhD in Neuropsychology from the Universit? de Montr?al in 2011. She did a first postdoctoral fellowship at the University of California, Berkeley, assessing the interplay between beta-amyloid deposition, vascular diseases and cognition in the preclinical phase of Alzheimer?s disease. She did a second postdoctoral fellowship at Northwestern University where she assessed the predictive value of neurovascular insults, such as deterioration of the blood-brain barrier or reduced cerebral vascular reactivity, to detect early changes associated with amyloid pathology. She just joined in August 2015 the PREVENT-Alzheimer Program at the Douglas (http://www.douglas.qc.ca/page/prevent-alzheimer-home).

He works in the new field of computational psychiatry, whose goal is to model the dysfunctional neural processes that lead to psychiatric symptoms. Title: Integrating decision systems: how the brain solves difficult problems Abstract: Humans often face decision-making problems too complex to solve exactly, forcing them to deploy a variety of approximations and heuristics. Here, we use reinforcement-learning modelling to examine performance on a planning task in detail, revealing multiple interacting strategies. First, subjects use both the topology of the task and the rewards to establish sub-goals that nearly optimally reduce computational cost. Second, instead of recomputing solutions to difficult problems they re-use previous results, providing one path towards the establishment of macro-actions or options. Third, they reflexively prune decision-trees when encountering salient losses in their mental search. Fourth, an alternative framing of the decision problem in terms of meta-reasoning suggests an important role for model-free, Pavlovian values in guiding the allocation of resources. These results highlight how humans are able deploy a vast panoply of strategies to achieve good choice performance. -------------- next part -------------- An HTML attachment was scrubbed...

Based on our understanding of the various steps, we have built a full pipeline that predicts Autism from rest-fMRI on unseen scanning site in the ABIDE dataset.
