Identification of microRNA targets using microRNA modulation techniques and gene expression arrays
Emily M. Anderson, Maren Mayer, Kevin Sullivan, Barbara Robertson, Žaklina Strezoska, Annaleen Vermeulen, and Devin Leake

By examining the overlap of messages down-regulated by miRNA mimics and up-regulated by miRNA inhibitors, we robustly identify miRNA-regulated messages, many of which have canonical seed matches and some which are not identied by standard target prediction programs.

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.

Accurate Normalization of Grain Samples Using Pressure-Based Volume Measurement Technology
Bill Gigante, John Thomas Bradshaw, Tanya Knaide

A common challenge experienced by sample screening facilities is identifying individual sample quantity prior to DNA extraction. Accurately identifying sample quantity allows the user to pipette exact amounts of extraction buffer into each well.

Britain Needs 'Super-Sub Bees'
Rare bees and insects must be protected to give British farmers a strong ‘reserve squad’ of pollinating species and prevent potential food shortages in the future, scientists say.
Massive Genome Shift in one Generation
A team of biologists has discovered that an agricultural pest that began plaguing U.S. apple growers in the 1850s likely did so after undergoing extensive and genome-wide changes in a single generation.
