Characterizing induced gene expression in Shigella flexneri following bile salt exposure
… utilizes host physiology, specifically bile salts as signals for invasion and virulence gene expression. This study aimed to build upon previous research analyzing the bile salts transcriptional profile of Shigella flexneri 2457T, in which an induction of the uncharacterized gene was …

SALT EXPOSURE AND NITROGEN METABOLISM IN TOMATO (SOLANUM LYCOPERSICUM L.): IMPROVEMENT OF THE RESILIENCE TO ABIOTIC STRESS
Salt stress is a critical challenge to plant growth and global food security, necessitating an in-depth understanding of the mechanisms plants employ to adapt to saline environments. Nitrogen (N) metabolism plays a pivotal role in regulating plant responses to salinity, with complex interactions …

Aging Assessment of High Voltage Single Component Room Temperature Vulcanized Silicone Rubber (RTV-1) Subjected to Aqueous Salt
… aging conditions such as UV, acid, and salt exposure from ocean mist. Loss of hydrophobicity due to damage of the hydrophobic methyl groups, as well as loss of mechanical strength due to depolymerization via hydrolysis as a result of aqueous salt exposure were the two main factors of …

Evaluation of the Impacts of De-Icing Salts on the Performance of Bioretention Media in Retaining Phosphorus From Urban Stormwater
… due to factors such as inputs of road de-icing salts. This study evaluates the impact of prolonged and periodic salt inputs on P retention by conducting column experiments using three different bioretention media with and without an amendment added. Non-amended columns showed net P release, …

Characterization of cDNA and Genomic Clones for a Palmitoyl-acyl Carrier Protein Thioesterase and an Osmotin-Like PR5 Protein in Gossypium Hirsutum.
… stress or osmotic stress (water deprivation or salt exposure). Osmotins may actually form pores in fungal membranes, leading to osmotic rupture and destruction of the fungal cells. A cotton osmotin-like PR5 cDNA insert of 1,052 base-pairs was isolated and shown to encode a preprotein of 242 …

The Effect of Salt Splash on Nylon 6,6
One of the most common environmental exposures that nylon undergoes, when used for automotive applications, is that of salt splash, which commonly occurs during winter driving. This study looks at the effect of various salts (NaCl, KCl, CaCl2) on the thermal and mechanical properties of nylon when …

BEYOND ARABIDOPSIS: UNRAVELLING THE HIDDEN WORLD OF CA2+ SIGNALLING ACROSS SPECIES VIA MULTISCALE IMAGING TECHNOLOGIES
… such as wounding, burning, flooding, and salt exposure. In conclusion, these integrated approaches establish a foundation for dissecting systemic signal propagation at the whole-plant level, across multiple species, and under a broad range of stress conditions.

Repair of damaged end regions of prestressed concrete girders using fiber reinforced polymer composite materials
… deterioration of the girder ends due to deicing salt exposure, thus reducing their shear strength. This thesis presents the results of the beginning stages of an Illinois Department of Transportation (IDOT) sponsored study to use FRP materials to repair and retrofit the damaged ends of …

The phenotypic and molecular responses of Listeria monocytogenes to stressors
… the phenotypic and molecular responses that such exposures have on resistance and virulence potential.<br/><br/>Using adaptation and repeated exposure assays L. monocytogenes cells were assessed for their ability to develop resistance and to adaptively respond to stressors. Using qRT-PCR and …

Toward improved assessment of freshwater salinization as a benthic macroinvertebrate stressor
… human activities is of growing concern globally. Salt pollution can cause adverse effects to aquatic biodiversity, ecosystem function, ecosystem services, and human health. In many regions of the world, and in coal-mining-influenced streams of the temperate forests of Appalachia USA, specific …
