Oil is a complex mixture of numerous compounds. Therefore, oil spills near shore can cause various adverse effects on coastal ecosystems. However, most toxicological assessments conducted on oil spill sites have focused on limited modes of toxic actions. In the present study, we utilized the Escherichia coli (E. coli) live cell array system (LCA) to identify novel modes of toxicities of the oil spill-affected sediments. For this purpose, sediment samples were collected from an area heavily polluted by Hebei Spirit oil spill (HSOS) incident of 2007...

Infiltration of heavy metal (HM) polluted wastewater can seriously compromise soil and groundwater quality. Interactions between mineral soil components (e.g. clay minerals) and dissolved organic matter (DOM) play a crucial role in determining HM mobility in soils. In this study, the influence of the timing of addition of DOM, i.e. concurrent with or prior to HMs, on HM mobility was explored in a set of continuous flow column experiments using well defined natural soil samples amended with goethite, birnessite and/or smectite...

Catheter-associated urinary tract infections (CAUTIs) represent one of the most common hospital acquired infections with significant economic consequences and increased patient morbidity. CAUTIs often start with pathogen adhesion and colonization on the catheter surface followed by biofilm formation. Current strategies to prevent CAUTIs are insufficiently effective and antimicrobial coatings based on antimicrobial peptides (AMPs) hold promise in curbing CAUTIs. Here we report an effective surface tethering strategy to prepare AMP coatings on polyurethane (PU), a common biomedical plastic used for catheter manufacture, by using an anti-adhesive hydrophilic polymer coating...

Plant-growth promoting rhizobacteria (PGPR) are studied as complements/alternatives to chemical fertilization in agriculture. Poor information however, exists on the potential of PGPR from undisturbed ecosystems. Here, we evaluated the plant growth-promoting (PGP) effect of rhizobacterial consortia from undisturbed Chilean arid-ecosystems (Consortium C1) and agro-ecosystems (Consortium C2) on plant biomass production. The PGP effects of C1 and C2 were assayed in wheat seedlings (Triticum aestivum L.) grown in pots under growth chamber conditions and in pots placed in an open greenhouse under natural conditions, using two different Chilean Andisols (Piedras Negras and Freire series) kept either at 30% or 60% of their maximum water holding capacity (MWHC)...

Sepsis-associated encephalopathy (SAE) is a common complication associated with poor prognosis in septic patients, but the underlying mechanism remains unclear. We hypothesized that disturbed neuregulin 1 (NRG1)-ErbB4 signaling in the parvalbumin interneurons was involved in sepsis-induced cognitive impairment in a mouse model of SAE. The SAE model was induced by cecal ligation/perforation (CLP). Animals were randomly divided into the following six groups: sham + vehicle group, sham + NRG1 group, CLP + vehicle group, CLP + NRG1 group, CLP + NRG1 + AG1478 (ErbB4 inhibitor) group, and CLP + minocycline group...

Fingertips wrinkle due to long exposure to water. The biological reason for this morphological change is unclear and still not fully understood. There are two main hypotheses for the underlying mechanism of fingertip wrinkling: the 'shrink' model (in which the wrinkling is driven by the contraction of the lower layers of skin, associated with the shrinking of the underlying vasculature), and the 'swell' model (in which the wrinkling is driven by the swelling of the upper layers of the skin, associated with osmosis)...

PURPOSE: Fatigue is a prevalent and burdensome effect of breast cancer. Fatigue has been linked to chronic inflammation, and diets high in antioxidant nutrients have been associated with lesser prevalence and severity of fatigue. Studies are needed, however, to test if antioxidant-rich diets could improve fatigue. METHODS: Pilot, randomized, trial conducted between January 2014 and April 2015, to investigate if a 3-month diet rich in fruit, vegetables, whole grains, and omega-3 fatty acid-rich foods, named the fatigue reduction diet (FRD), improved fatigue and sleep compared to an attention control, named the general health curriculum (GHC)...
