Adsorption of molecular layers on hydrophilic SiOxNy probed by DPI technique
The AnaLight Quantum with a new vapour deposition setup and improved protocol has been used to study the self-organization of 5CB molecules deposited from their vapour phase onto a hydrophilic silicon oxynitride surface. Although slightly less accurate, the results are in good agreement with the …

Computational Modelling and Optimization of Dry Powder Inhalers
Dry powder inhalers (DPIs) are a common therapeutic modality for lung diseases such as asthma, but they are also used to treat systemic diseases such as diabetes. Advantages of DPIs include their portable design and low manufacturing costs. Another advantage of DPIs is their breath activation, …

The Ligand and Membrane-binding Behaviour of the Phosphatidylinositol Transfer Proteins (PITPa & PITPb)
… proteins using dual polarization interferometry (DPI). DPI is a technique that measures protein binding affinity to a flat immobilized lipid bilayer. In addition, we also measured how quickly these proteins transfer their ligands to lipid vesicles using a fluorescence resonance energy transfer …

Fate of Salmonella and Listeria monocytogenes in different frozen produce commodities
… 6, 10, 15, 30, 60 and 90 days post inoculation (dpi), after storage at -18±2°C. Listeria monocytogenes monitoring followed the same structure, with an additional timepoint at 180 dpi. For objective 2, ten-gram samples of cut-cantaloupe were inoculated with a five-strain Salmonella cocktail at ~ 4 …

Characterization of Atypical Hemolytic Ornithobacterium rhinotracheale Isolates and Comparison with the Normal Non-Hemolytic Phenotype
… with the NH isolate at 7 days post-inoculation (dpi). NH inoculates also had significantly higher antibody levels on ELISA at 14 and 21 dpi and histopathological lesion scores for lung at 7, 14, and 21 dpi. The NH isolate could be re-isolated from NH-inoculated poults through 21 dpi; whereas the …

Evaluating the Cross-Contamination Risks of Salmonella and Generic Escherichia coli on Agricultural Ground Covers in Produce Pre-Harvest Production
… 5, 7, 30, 60, 90, and 140 days post-inoculation (dpi), coupons were enumerated for Salmonella. Coupons of plastic mulch were also spot inoculated with a green-fluorescent protein-tagged generic Escherichia coli and held in a growth chamber, greenhouse, and field environment for enumeration at 0, …
