Next Event

Monday, July 14: The University of Minnesota Visible Heart® Laboratory

Abstract:

 

The Visible Heart® Laboratory was established at the University of Minnesota in collaboration with Medtronic as a design tool for engineers and researchers. 

 

In his presentation, Dr. Paul Iaizzo will present the methodologies of the Visible Heart® Laboratory:

 

An isolated heart preparation in which essentially normal pumping activity of all four chambers of the heart is preserved, allowing for the use of the preparation in conjunction with investigations of electrode leads, catheters, cardiac implants and other medical devices intended to be used in or on a beating heart. The preparation may also be employed to investigate heart functions, in the presence or absence of such medical devices. In order to allow for visualization of heart structures and devices located within the chambers of the heart, a clear perfusate such as a modified Krebs buffer solution with oxygenation is circulated through all four chambers of the heart and the coronary vasculature. The preparation and recordings of the preparation may be used in conjunction with the design, development and evaluation of devices for use in or on the heart, as well as for use as an investigational and teaching aid to assist physicians and students in understanding the operation of the heart.

About the speaker:

NOVEMBER 15, 2007: Extracting Behavior Patterns from Videos by Dr. Chih Lai        

Automatically extracting previously unknown behavior patterns from videos that track animals with various physical conditions can accelerate our understanding of animal behaviors and their influential factors, resulting in major medical and economic benefits. Unfortunately, extracting behavior patterns from videos recordings remains as a very challenging task due to their extensive duration and the unstructured natures. This task is further complicated in a completely darken animal cage with inconsistent infrared lighting, moving reflections, or other cage debris such as the cage bedding. In this research, we propose a new motion model that enables us to measure the similarities among different animal movements in high precision so a clustering method can correctly separate recurring movements from infrequent random movements. More specifically, our model first transforms the spatial and temporal features of animal movements into a sequence of color images, referred to as color motion maps (CMMs). The task of mining recurring behavior patterns is then reduced to clustering similar color images in a database. We will use a real infrared video to demonstrate the capability of our model in capturing distinguished but brief animal movements that are embedded within a sequence of other animal movements.

September 6, 2007:  Short-Range Wireless Communications for Medical Devices by Dr. Harjani

 

The desire for pervasive and untethered connectivity has increased the interest in short-range wireless radios. There are a number of bio-related applications for such radios including wireless hearing aids and body area networks. The performance limit of wireless communication systems is usually set by the RF front-ends. In particular, portable wireless medical devices require high performance compact designs that consume minimum power. In this talk we will first provide an overview of some of the system level design constraints and discuss their impact on circuit design. We then describe some new designs developed at the University of Minnesota. In particular, we describe some recent developments in circuits for power efficient UWB communications. The talk will provide an overview of both recent and ongoing research results.

July 10, 2007:  DNA Sequencing: Which Kind of Sequencing We Need by Tarmo Puurand

 

DNA sequencing is the method for getting the blueprint information for living organism genetic makeup. There are several methods for sequencing. The most known of them are based on the Sangers method. From a biologist perspective a question remains: does the existing sequencing technology fulfill researchers today’s needs?

 

In the seminar, the presenter will describe today’s instruments of whole genome analysis of human genomic data including sequencing methods, human sequence variations and corresponding markers, association studies, trace data, and Hapmap data. Due to the complexity of the questions biologists are asking of DNA data, there is a need for better method. 

 

Tarmo Puurand is a PhD student in University of Tartu, Estonia. His PhD thesis focuses on human variations that are findable in silico. In 1993, he received a BA in molecular biology from University of Tartu, Estonia. In 2004, he received a MS in bioinformatics from the University of Tartu. He was also employed in the Estonian pharmaceutical and biotechnology industry.

June 20, 2007: MEMS-based Magnetic Devices for Biosensor Applications by Dr. Mark Tondra

 

Micro-scale magnetic sensors and actuators, generically called “magnetic MEMS”, can be applied to many biosensing applications.  Magnetic nanoparticles are commonly attached to biomolecules through a specifically designed linkage in order to make the analyte of interest “magnetic”.  Then, magnetic sensors can detect the presence and quantity of the magnetic labels.  Also, magnetic forces can be applied, on a micrometer scale, to separate, direct, and concentrate the analytes. 

 

This presentation will start with examples of magnetic tagging and detection using magnetoresistive sensor chips for DNA and immunoassays.  A magnetically based hand-held flow cytometer, whose development is in progress, will be described.  And then some of the practical manufacturing challenges in combining microfluidic sample handling cartridges with microelectronic sensors will be presented. 

 

The ultimate goal of much of this development work is to have high performance biosensors in a cheap and easy-to-use format.

 

Mark Tondra is the founder and Chief Scientist at Diagnostic Biosensors, LLC (Minneapolis, MN).  The company was started in 2005 in order to focus on development of magnetic biosensors for rapid and disposable diagnostic applications.  Prior to that, he worked at NVE Corp. (Eden Prairie, MN) from 1996 through 2005.  At NVE, he collaborated on many projects to develop Giant Magnetoresistive (GMR) and magnetic tunnel junction (MTJ) sensors for uses in biological, industrial, and military applications.  In 1996, he received the PhD degree from the Univ. of Minnesota, Twin Cities, in Solid State Physics, specializing in magnetism and statistical mechanics.  In 1989, he received the BS degree from the Univ. of Wisconsin-Madison in Physics and Mathematics.  He grew up in Ames, IA, graduating from Ames HS in 1985.
