The ability of nanoparticles (NPs) to induce oxidative stress on organisms has been linked to NP cytotoxicity and genotoxicity for a variety of organisms. One proposed mechanism of this increased oxidative stress is the ability of NPs to generate reactive oxygen species (ROS). Due to the dynamic nature and small...
Nanoparticles (NPs), defined by their size (1-100 nm), are increasingly incorporated into commercial and industrial products due to their high surface area and unique properties. They can be designed for specific applications by manipulating composition, size, shape, and surface functionalization. As NP production and complexity increases, there is a need...
Zero valent iron nanoparticles effectively remediate groundwater contaminants due to their catalytic properties and enhanced surface area. However, these properties contribute to particle agglomeration, decreasing their effectiveness. In this study, we examined the effect of two stabilizing agents (gum arabic (GA) and sodium carboxymethyl cellulose (CMC)) on particle stability, toxicity,...
Within the past two decades, the rise of nanotechnology has provided various technological and industrial sectors with avenues for significant growth and improvements to existing practices. With the inherent qualities which make materials on the nanoscale unique in behavior and function, there are limitless applications of nanotechnology. One of the...
The level of reactive oxygen species (ROS) is tightly regulated in biological systems as overproduction can lead to oxidative stress and result in a number of diseases. Due to its negative effects, antioxidants are studied and used against ROS in medicine, pharmaceuticals and therapeutics. Because of issues with the uptake...
Characterizing the hydrophobicity of nanoparticles can help us understand their fate and transport in the environment, as well as how nanoparticles may interact with biological systems. However, contact angle and partition coefficient have limitations in measuring the hydrophobicity of nanoparticles, thus promising methods to measuring the hydrophobicity of nanoparticles are...
BACKGROUND: Predictive modeling of the biological effects of nanomaterials is critical for industry and policymakers to assess the potential hazards resulting from the application of engineered nanomaterials.
METHODS: We generated an experimental dataset on the toxic effects experienced by embryonic zebrafish due to exposure to nanomaterials. Several nanomaterials were studied,...
The alien abduction phenomenon has garnered considerable media attention in the last fifteen years, including many representations in books, film, and television. An overview of significant abduction literature is presented. Contrasts and comparisons are noted between popular written accounts and both the visual representations they engender and reports outside the...
A pest management program for variegated cutworm (VC), Peridroma
saucia (Hubner), in Oregon peppermint was developed based on studies
of pheromone trapping, sampling methods, and economic thresholds.
Pheromone traps effectively trapped VC males and were used to
reflect development and oviposition trends. Trap height was linearly
correlated to moth catch...
The relationships of serum T₄
(thyroxine) levels and liver
nicotinamide nucleotide coenzyme (NAD and NADP) levels with production
of traits of beef cattle were investigated at both weaning (182
kg) and following performance testing (363 kg). In addition, the value
of these parameters as selection criteria for improved performance
was...
