Background and purpose: 2,4 dichlorophenol is one of the most important components of organochlorine. High resistance against degradation, creating odor and taste in water, high toxicity and being carcinogen have made this pollutant a great concern. Current study batch was done to investigate the adsorption of 2,4 dichlorophenol onto Magnetic Graphene Oxide Particles (MGO NPs). Materials and...
MicroRNAs (miRNAs) are known to have complicated functions in aquatic species, but little is about the role of miRNAs mollusk species under environmental stress. In this study, we performed small RNA sequencing characterize differentially expressed different tissues (whole tissues, digestive glands, gills, and gonads) blue mussels ( Mytilus galloprovincialis ) exposed cadmium (Cd). summary, 107 ...
Abstract Polycyclic aromatic hydrocarbons (PAHs) in atmospheric particulate matter have adverse effects on human health, yet total PAH concentrations should overestimate the toxicity compared to bioavailable amount of PAHs. To explore this hypothesis, we measured PAHs oral bioavailability vitro with aerodynamic diameter lower than 10 µm (PM ) using a test that mimics digestive system. This assa...
OBJECTIVE To assess the efficacy, as well as the long term duration, of a new procedure for the rehabilitation of visuospatial neglect in patients with right hemisphere stroke. METHODS Patients with right unilateral hemispheric damage identified with neglect were assigned to a treatment (T+) or a control (T-) group. The treatment consisted in abolishing all visual inputs from the right hemisp...
BACKGROUND It is generally accepted that antibacterial properties of Ag nanoparticles (AgNPs) are dictated by their dissolved fraction. However, dissolution-based concept alone does not fully explain the toxic potency of nanoparticulate silver compared to silver ions. METHODOLOGY/PRINCIPAL FINDINGS Herein, we demonstrated that the direct contact between bacterial cell and AgNPs' surface enhan...
PURPOSE Contact lens-associated solution toxicity manifests as generalized, mild punctate epithelial fluorescein staining and usually is widely reported as asymptomatic, with no substantial clinical sequelae. This study examined the relationship between solution toxicity and corneal infiltrative events (CIEs) in soft contact lens daily wear. METHODS Several nonrandomized interventional clinic...
Background and purpose: 2, 4 dinitrophenol is the most important nitrophenol compound that is widely used in paints, adhesives, wood preservatives, solvents, pesticides, and explosive materials. Because of the high toxicity and non-biodegradability of 2, 4 DNP, must be prevented from entering the water body. The aim of this study was to evaluate the performance of ordered mesoporous carbon CMK-...
Lectins are sugar-binding proteins widely distributed in nature with many biological functions. Although many lectins have a remarkable biotechnological potential, some of them can be cytotoxic. Thus, the aim of this study was to assess the toxicity of five lectins, purified from seeds of different species of Canavalia genus. In order to determine the toxicity, assays with Artemia nauplii were ...
The aim of this study is to identify the biochemical mechanism of phosphine toxicity and resistance, using Caenorhabditis elegans as a model organism. To date, the precise mode of phosphine action is unclear. In this report, we demonstrate the following dose-dependent actions of phosphine, in vitro: (1) reduction of ferric iron (Fe3+) to ferrous iron (Fe2+), (2) release of iron from horse ferri...
