A Cr₂0₃, and cellulose fibre mixture was used with cattle, in
three grazing and two semi-restricted experiments, to study the mode
of its excretion, the possibility of using it in a once-daily dosing and
grab-sample regime to estimate fecal output and in a field experiment
to test a hypothesis involving...
Dendrimers are well-defined, polymeric nanomaterials currently being investigated for their biomedical applications. Initially, higher generation (size) dendrimers were of interest because of their drug carrying capacity. However, increased generation was associated with increased toxicity. The objective of the present study was to investigate the role of surface charge and generation...
Dendrimers are well-defined, polymeric nanomaterials currently being investigated for biomedical applications such as medical imaging, gene therapy, and tissue targeted therapy. Initially, higher generation (size) dendrimers were of interest because of their drug carrying capacity. However, increased generation was associated with increased toxicity. The majority of studies exploring dendrimer toxicity...
Inherent nanomaterial characteristics, composition,
surface chemistry, and primary particle size,
are known to impact particle stability, uptake, and
toxicity. Nanocomposites challenge our ability to predict
nanoparticle reactivity in biological systems if they
are composed of materials with contrasting relative
toxicities. We hypothesized that toxicity would be
dominated by the nanoparticle...

Home-based counseling (HBC) occurs when counselors provide therapy services to individuals and families within the clients’ home environment. Since its inception in the 1980s, HBC has become a common practice within the counseling field. In 2014, the U.S. Bureau of Labor Statistics (2014) named HBC one of the fastest-growing divisions...
This investigation attempts to demonstrate that the development
of the early 20th century biological enterprise involved a striving for a
unifying theoretical perspective. A skeletal substantiation of this is
given by an overview of early 20th century biology in which some
biologists began recognizing a multiplicity of different orders of...
