Specificity and functionality of microRNA inhibitors
Barbara Robertson, Andrew Dalby, Jon Karpilow, Anastasia Khvorova, Devin Leake and Annaleen Vermeulen

Our findings indicate that features important for natural miRNA target recognition also appear to be important for inhibitor specificity. Understanding the specificity of inhibitors allows for better interpretation of inhibitor activity in endogenous systems.

Alternative miRNA design for therapeutic RNAi applications
Anja van Brabant Smith, Barb Robertson, Annaleen Vermeulen, Christina Yamada, Angela Reynolds, Anastasia Khvorova, Devin Leake

For in vivo applications, the design of miRNA inhibitors and miRNA mimics must be optimized for stability and potency. However, stabilized miRNA mimic molecules can lose functionality compared to standard miRNA mimic molecules due, in part, to the activity of the stabilized passenger strand acting as a miRNA inhibitor. We discuss how mismatches affect the activity of the stabilized miRNA mimics, perhaps by generating a passenger strand that is less functional as an inhibitor molecule.

Integrating Fluorescent Carbon Nanodot Synthesis and Optical Detection of Methylmercury
Carlos Bendicho, Isabel Costas-Mora, Vanesa Romero, Isela Lavilla

In the last years, a great interest toward development of optical nanoprobes has arisen, so fluorescent nanomaterials have been implemented in analytical systems for the detection of several species. In this work, a novel assay that integrates the synthesis of fluorescent carbon dots (CDs) and sensing within one step, for the fast, sensitive and selective detection of methylmercury is presented.

Impact of Molecular Surface Charge on Electrical Impedance Spectroscopy Biosensing
Y. Ram, T. Yoetz-Kopelman, A. Freeman and Y. Shacham-Diamand

Molecular surface charge was found to be the dominant parameter when monitoring protein binding events by Electrical Impedance Spectroscopy with a charged redox couple. A biosensing device was fabricated, and a physical model was derived to explain the results.

Investigating the Effects of Commercial Antimicrobial Agents on Human Corneal Epithelial Cell Membranes
Ian J. Horner, Jerod J. Hurst, Nadine D. Kraut, Alyssa A. Rook, Crystal M. Collado, G Ekin-Atilla Gokcumen, and Frank V. Bright

Several commercial multi-purpose solutions (MPS) products contain polyhexamethylene biguanide (PHMB) and/or polyquaternium-1 (PQ-1) as antimicrobial agents. In this poster we report the effects of PHMB and PQ-1 on small unilamellar vesicles (SUV) that we have designed to mimic the average human corneal epithelial cell membrane.

A multiplexed amplicon sequencing technology for FFPE and circulating, cell-free DNA
Laurie Kurihara, Catherine Couture, Julie Laliberte, Sukhinder Sandhu, Jonathan Irish, Tim Harkins and Vladimir Makarov

A novel amplicon approach allowing for hundreds of amplicons to be multiplexed in a single tube with a two workflow from sample to sequencer.

Stable Chloroplast: Myth or Reality?
Shailesh Joshi and Dyfed Evans

Chloroplasts principally encode the photosynthetic machinery in Viridiplantae. It has long been accepted that in photosynthetic plants chloroplast genomic structure is uniquely stable as it is maternally and clonally inherited. The first chloroplast genomes sequenced supported this view. The current study was undertaken to address the potential issue of global chloroplast(in)stability.

Validation of Collection and Extraction Methods of Saliva for Use in Biomarker Research
Sarah E. Hurst and Brandon T. Hall

This poster investigates the collection and extraction methods of saliva for use in biomarker research.

Rapid Detection of Somatic Mutations in Cancer Genes
Michael J. Powell et. al.,

Rapid higly sensitive detection of tumor gene mutations in DNA derived from FFPE or plasma samples can be achieved with QClamp PCR technology.

Genetic Variant May Help Explain Why Labradors Are Prone To Obesity
A genetic variation associated with obesity and appetite in Labrador retrievers – the UK and US’s favourite dog breed – has been identified by scientists at the University of Cambridge. The finding may explain why Labrador retrievers are more likely to become obese than dogs of other breeds.
How Scientists Use DNA to Track Disease Outbreaks
They’re the top questions on everyone’s mind when a new disease outbreak happens: where did the virus come from? When did this happen? How long has it been spreading in a particular country or group of people?
