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.

Aptamer-Based Electrochemical Biosensing Platform for Detection of Hormonal Pollutants in Water
Contreras Jimenez, G.; Eissa, S.; Ng, A.; Zourob, M.; Siaj, M.

A novel detection mechanism based on aptamers has been developed to detect small molecules as hormones, antibiotics, toxins, drugs, etc. For first time, an aptasensor to detect progesterone has been developed.

An investigation into the effects of aging on automotive bumper samples by xylene soluble flow injection polymer analysis (XS-FIPA)
Bassem Sabagh, Wei Sen Wong, Bernd Tartsch

This poster describes the use of flow injection polymer analysis (FIPA) as an analytical tool for xylene soluble (XS) determination with quick and easy simultaneous measurements of molecular weight (MW), intrinsic viscosity (IV) and XS%. The technique was applied to automotive bumper samples which had undergone an aging test. The results from the XS-FIPA technique highlight the differences caused by the aging process.

The role of AHPCO Technology in reducing allergic rhinitis cases as Air Purifier, Surface Sterilizer and Ice Maker sterilizer
Dr. Nabarun K. Ghosh, PhD1, Dr. Constantine K. Saadeh, MD FAAAAI2, Dr. Jeff Bennert, PhD CTN3 and Ms. Griselda Estrada, BS1

Dirty ice makers can cause potential health hazards. To prevent any potential contamination, the interior surfaces of the ice machine must be cleaned and sanitized regularly. This report justifies the demand and use of novel equipment that will sanitize the surface of an ice machine continuously. We evaluated the Bi-Polar® unit built by Air Oasis (1.2) in sanitizing the ice machine surface.

Tolerance to Allergenic Foods Following Food Oral Immunotherapy (FOIT)
AR Hague1, RL Wasserman1,2, SK Silvers1,2, RW Sugerman1,2, M Herbert3

We report on 21 patients who completed FOIT (food oral immunotherapy) escalation followed by a period of maintenance dosing and later underwent a tolerance FC (food challenge). 90% of tested FOIT patients and 94% of patients who met our pre-defined criteria for tolerance FC achieved tolerance to their allergenic food.

Single Practice Six-Year Experience Treating Food Allergy With Oral Immunotherapy
DM Pence1, AR Hague1, RL Wasserman1,2, SK Silvers1,2, RW Sugerman1,2, M Herbert3

We report a more-than-six-year experience with food oral immunotherapy (FOIT) in a private allergy practice setting. Most patients can be desensitized to one or more allergenic foods. Ongoing evaluation and modification of the FOIT procedures improves outcomes and acceptability. FOIT can be successfully performed in an allergy office.

When Single Dimension GC Separations Fail: Exploring Real World Applications for Comprehensive Two=Dimensional GC (GCxGC)
Joe Binkley, Elizabeth Humston-Fulmer, David E. Alonso, and Lorne Fell

Examples will be highlighted for food/flavor/fragrance, metabolomic, and petrochemical application markets. The advantage in number of compounds detected and overall quality of their mass spectral library similarity scores, as compared to one-dimensional methods will be clearly demonstrated.

Ichthyophonus vs. Proteins: Should we be eating these fish?
Alisa Aist

The project, Ichthyophonus vs. Proteins, analyzes the effect of Ichthyophonus on the protein content of Halibut from Homer. This experiment found that Ichthyophonus does not have a significant effect on the protein content of the tested Halibut. The findings confirm the belief that Ichthyophonus is not harmful to humans and the Halibut are still safe to eat.

Uncertainty estimation of an analytical method for analysis of fumonisin B1 in four types of rice intended for consumption human
Petrarca, M.H.; Rossi, E.A.; Sylos, C.M.

The expanded measurement uncertainty of a sample preparation method based on QuEChERS procedure for the determination of fumonisin B1 in four types of rice, using HPLC-FLD after precolumn derivatisation with ortho-phthaldialdehyde, was estimated from in-house validation data.
