Christopher Dydula (Carleton University)14/06/2016, 19:00Physics in Medicine and Biology / Physique en médecine et en biologie (DPMB-DPMB)Poster (Student, In Competition) / Affiche (Étudiant(e), inscrit à la compétition)In medical x-ray imaging a major challenge is to obtain adequate soft tissue contrast. The goal of our research is to develop a high soft-tissue contrast x-ray technique based on the detection of low-angle scattered photons. Scattered photons comprise up to 90% of the radiation downstream of the patient and can provide information in addition to that of the transmitted primary x rays. In...Go to contribution page

Mr Deok Hyun Jang (Department of Physics, Ryerson University, Toronto, Ontario, Canada)14/06/2016, 19:02Physics in Medicine and Biology / Physique en médecine et en biologie (DPMB-DPMB)Poster (Student, In Competition) / Affiche (Étudiant(e), inscrit à la compétition)Dual-energy X-ray Absorptiometry (DXA) is currently the “gold standard” for measuring bone mineral density (BMD). Due to dependency of DXA on the atomic composition of bone, deposition of bone seeking elements that differ in atomic numbers from calcium (Ca, Z=20) can cause inaccurate estimation of BMD. One of the most notable elements of concern is strontium (Sr, Z=38), which is used to...Go to contribution page

Michaël Smith (Cégep de Rivière-du-Loup)14/06/2016, 19:04Physics in Medicine and Biology / Physique en médecine et en biologie (DPMB-DPMB)Poster (Student, Not in Competition) / Affiche (Étudiant(e), pas dans la compétition)Selon l'équation de la friction visqueuse, la force de friction entre deux surfaces séparées par une couche de fluide newtonien augmente proportionnellement avec la viscosité, l'aire de la surface de contact et la vitesse de déplacement relatif. La force de friction décroit avec l'épaisseur de la couche de fluide. L'expérience présentée vise à vérifier facilement (et avec un matériel...Go to contribution page

Frédéric Lirette (Cégep de Rivière-du-Loup)14/06/2016, 19:06Physics in Medicine and Biology / Physique en médecine et en biologie (DPMB-DPMB)Poster (Student, Not in Competition) / Affiche (Étudiant(e), pas dans la compétition)Selon la loi de Poiseuille, le débit d'écoulement d'un fluide dans une conduite cylindrique est proportionnel au gradient de pression et au rayon de la conduite élevé à la puissance quatre. Il est aussi inversement proportionnel à la viscosité du fluide. La loi de Poiseuille fut d'abord établie en lien avec l'étude de l'écoulement du sang dans les veines et les artères. L'expérience...Go to contribution page

Dylan Malenfant (University of Windsor)14/06/2016, 19:08Physics in Medicine and Biology / Physique en médecine et en biologie (DPMB-DPMB)Poster (Student, In Competition) / Affiche (Étudiant(e), inscrit à la compétition)There is an urgent demand from many sectors (health, environmental safety, security, and food-processing) for a diagnostic test to rapidly and accurately identify bacterial pathogens. In recent years, it has been shown that laser-induced breakdown spectroscopy (LIBS) can provide a real-time bacterial cell elemental assay. On the basis of this assay, sensitive and specific discrimination...Go to contribution page

Austin Nehring14/06/2016, 19:10Physics in Medicine and Biology / Physique en médecine et en biologie (DPMB-DPMB)Poster (Student, Not in Competition) / Affiche (Étudiant(e), pas dans la compétition)The aggregation of red blood cells into coin-like stacks called rouleaux is associated with a number of underlying causes including infections and diseases such as cancer. Rouleaux formation occurs when the protein concentration in blood plasma is high. Hence, one possible cause for rouleaux formation is red blood cells clumping together due to depletion forces. In the case of several large...Go to contribution page

Benjamin MacPherson Barlow (University of Ottawa)14/06/2016, 19:12Physics in Medicine and Biology / Physique en médecine et en biologie (DPMB-DPMB)Poster (Student, In Competition) / Affiche (Étudiant(e), inscrit à la compétition)The Atomic Force Microscope (AFM) lets us reach out and touch cells, on force and length scales native to them. But what *physically* happens when the AFM's tip touches a cell? The membrane is a first point of contact, and that is why we begin by studying vesicles —cell membranes laid bare. Using Coarse-Grained Molecular Dynamics simulations, we study the relaxation of uniaxially compressed...Go to contribution page

Sean Wolfe (Plasmionique Inc.)14/06/2016, 19:14Physics in Medicine and Biology / Physique en médecine et en biologie (DPMB-DPMB)Poster (Non-Student) / affiche (non-étudiant)Plasma-based processes are increasingly finding applications in a variety of fields, including biomaterial engineering and medicine. This proliferation, in part, is due to the fact that the plasma state of matter not only allows surface modifications with monoatomic layer precision, but also offers the opportunity of synthesizing new materials and nanostructures that could influence the cell...Go to contribution page

Prof. Tigran Galstian (University Laval)14/06/2016, 19:18Physics in Medicine and Biology / Physique en médecine et en biologie (DPMB-DPMB)Poster (Non-Student) / affiche (non-étudiant)With the continued miniaturization of endoscopic imaging tools, the use of mechanical adaptation (focusing, etc.) becomes difficult. This is particularly true for the "mobile" or portable implants, including the freely behaving animals. In the current presentation we shall describe the concept of a motion less adaptive imaging on the example of a stationary (still large) system using liquid...Go to contribution page

Despite considerable technical progress in recent years, DNA sequencing is still a time and resource consuming procedure. Finding inexpensive, easy, and reliable alternative DNA sequencing strategies is a tall task. As recently demonstrated on biological pores, a promising approach to this challenge is the use of nanopores to characterize single strands of DNA. The advantages of nanopore...

The last decade has seen significant advancements in nanofluidic devices to study transport processes at the single-molecule level. In particular, exciting results have been obtained through the study of passage of nucleic acids through solid-state nanopores (ssNP). ssNP are nanometer-sized holes in thin dielectric membranes, which have emerged as a versatile tool to investigate a wide range...

Nanopores have proven to be useful single-molecule sensing tools in the past two decades. One of the many promising applications of these electrical nano-sensors is to act as molecular counting devices with single-molecule sensitivity, essentially determining concentrations of specific molecular species. To achieve this, it is essential to develop a better understanding of the nanopore capture...

Patients who receive targeted radionuclide therapy (TRT) for cancer treatment suffer from damaging unwanted healthy body tissues and may receive unexpected dose to healthy organs as an inadvertent consequence of their treatment. In particular, they risk significant dose to critical and secondary organs, e.g. bone marrow, gonads, uterus etc., which may cause long- or short- term damage for...
