Label-free Identification of Microorganisms using a Contact-less Dielectric Microsensor
Microfabricated biochips are developed to continuously monitor cell population dynamics in a non-invasive manner. In the presented work we describe the novel combination of contact-less dielectric microsensors and microfluidics to promote biofilm formation for quantitative cell analysis.

Development of a Lab-on-a-Chip for the Characterization of Human Cells
Cell chips are developed to continuously monitor mammalian cell population dynamics in a non-invasive manner. In the presented work we describe the design, fabrication and characterization of a lab-on-a-chip for quantitative cell analysis.

High Throughput Screening with Infectious Agents: Equipment Choices and Strategies
At Southern Research Institute we routinely conduct HTS campaigns using infectious agents at the BSL-2 (Biosafety Level) and BSL-3 level. Here we discuss how we have successfully screened over one million compounds in anti-viral (Severe Acute Respiratory Syndrome, Influenza, Highly Pathogenic Avian Influenza) and anti-microbial (Staphylococcus aureus, Escherichia coli, Mycobacterium tuberculosis) screens in BSL-2 and BSL-3 containment.

The Impact of the PCK1 Gene and PPCK1 Promoter Polymorphism 232C→G on the Incidence of TIIDM in Oji-Cree Natives of Ontario
The reported incidence of Type II Diabetes Mellitus (TIIDM) in Oji-Cree Natives is the highest in the world. This poster presents the impact of the PCK1 gene on TIIDM incidence in Oji-Cree Natives with particular attention to the role of SNP 232C→G on the transcription rate of phosphoenolpyruvate carboxykinease (PPCK1).

EasyBeacons™ - new Probes Ideal for Realtime PCR Detection of Methylation Status of Single CpG Duplets and SNPs
The EasyBeacons™ presented here are based on the novel technology Intercalating Nucleic Acid, INA®, linked to a fluorophore and a quencher. INA® is composed of normal DNA nucleotides and Intercalating Pseudo Nucleotides (IPNs). The fact that the EasyBeacons™ are mostly composed of normal DNA nucleotides means that in many respects EasyBeacons™ behave like DNA based probes, allowing use of standard buffers, primers and enzymes and hence reduces the optimisation efforts.

Novel Fluidics Microbead Trap/Flow Cell Enhances Speed/Sensitivity of Bead-Based Bioassays Up to 5-Fold
Pacific Northwest National Laboratory (PNNL) has developed a micro/nano particle trap that allows surface-functionalized magnetic or non-magnetic particles to be trapped with subsequent perfusion of sample, reagents and wash solutions, yielding significant (up to 5-fold) improvements in assay speed and sensitivity, while significantly reducing sample matrix effects.

Utilizing High Speed Photography to Optimize Low Volume Dispensing Conditions
In this study we use high-speed photography as a feedback mechanism for adjusting the Nanodrop instrument dispense settings to improve the positional dispense accuracy of low volume (nanoliter) drops. These same parameters can be investigated, with various fluid classes, to reduce deleterious effects on dispensing performance such as deflected streams, satellite formation, secondary pulses and drop deformation.

Combined Immune Parameters and X-ray data in Early Prediction of Anti-Tuberculosis Chemotherapy Response
20 tuberculosis (12 slow-responders and 8 fast responders) patients were treated with directly observed short course anti-tuberculosis chemotherapy. Chest X-ray was performed. sICAM-1 and suPAR were measured in serum by ELISA, TNFRs using the luminex technology. General discrimination analysis on selected analytes gave, 91.66% and 87,50% correctly classify fast responders and slow responder respectively. The support vector machine analysis gave 100% correct classification.
