Raman Imaging and Polarization Spectroscopy of Draw-Induced Order in Poly-L-lactic Acid
Lakshmi Balaraman, Venkata N K Rao Bobba, and John. F. Turner II

The work in the poster is based on Raman Imaging and Raman Polarization spectroscopy . The sample used is Poly-L-lactide(PLLA).

Improved Small RNA Library Preparation Workflow for Next-Generation Sequencing
Sabrina Shore, Jordana Henderson, Anton McCaffrey, Gerald Zon, Richard Hogrefe

We describe an optimized small RNA NGS library prep workflow using chemically modified adapters which suppresses adapter dimers, allows for RNA inputs down to 1 ng and eliminates the need for a gel purification step, thus allowing full automation not previously possible.

Combined Use of Rheometry and GPC/SEC for Characterising Ionic Polysaccharides
John Duffy, Bernd Schaefer, Bert Postma

This poster shows how Rheometry and GPC can be complementary tools for characterising the behaviour of polysaccharides in solution

Electrical Fusion Machine - New electrical fusion system for x-ray fluorescence analysis
Dr. Rainer Schramm, FLUXANA GmbH & Co. KG; Prof. Marie-Louise Klotz, Hochschule Rhein-Waal, Dr. Myint Myint Sein, Hochschule Rhein-Waal

This poster describes sample preparation in x-ray fluorescence analysis using the Electrical Fusion Machine by FLUXANA.

Rate and Mechanistic Investigation of Eu(OTf)2-Mediated Reduction of Graphene Oxide at Room Temperature
Tufan Ghosh, Sandeepan Maity and Edamana Prasad

Eu(OTf)2 has been introduced as an efficient reagent for the reduction of graphene oxide. Details kinetic studies have been performed which suggests that, the method is more efficient compared to that of other commonly used reduction methods.

Specificity of highly potent miRNA inhibitors
Barbara Robertson, Andrew Dalby, Yuriy Fedorov, Jon Karpilow, Anastasia Khvorova1, Devin Leake, Annaleen Vermeulen

miRNA inhibitors are invaluable tools for elucidating the roles of miRNAs. However, potent inhibitors may also affect other miRNAs. To understand the potential cross-reactivity of miRNA inhibitors, various miRNA inhibitor designs were systematically tested. We demonstrate that mismatches both within and outside the seed region of the miRNA interfere with inhibition. Our findings indicate that features important for natural miRNA target recognition are also important for inhibitor specificity.

Targeting Cancer Stem Cell-Related miRNAs for Prostate Cancer Therapy
ANSHIKA NIKITA SINGH, MEGHNA BARUAH, NEETI SHARMA

The poster focuses on the pivotal function of miRNAs in tumorigenesis by regulation of self renewal and apoptosis via cancer stem cell signalling pathways with special focus on their regulation of Epithelial to Mesenchymal transition in metastatic prostate cancer.

siRNA Screening: Development of Hit Stratification Strategies
Žaklina Strezoska, Annaleen Vermeulen, Emily M. Anderson, Anja Smith, Devin Leake

This poster compares different approaches to hit stratification and validation after an initial screen. Standard siRNA reagents deconvoluted from a pooled set of four were compared to a pooled set of four specificity enhanced reagents. High confidence hits were similar. To explore the validity of low confidence hits, a chimeric approach was used whereby a gene-specific seed sequence was introduced into a non-targeting siRNA scaffold. This work resulted in new hit stratification strategies.

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.

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.
