The widespread use of carbon nanotubes (CNTs) has raised concerns about the human health and ecological effects CNTs released into environment. Bacteria play an important role in bioremediation waste treatment, their enzymes are mostly responsible for degradation contaminants. However, there still only a few reports bacterial CNTs, evidence showing involvement CNT with mechanisms never been rep...

The purpose of the present investigation was to determine if the horseradish peroxidase (HRP) technique could be used as a method for labeling sensory nerve fibers (specifically, tooth pulp afferents) for detailed ultrastructural analyses. HRP injected into the trigeminal ganglion of adult rats was taken up by ganglion cell bodies and transported anterogradely to their peripheral endings in the...

Sorption-desorption behavior of phenol and o-cresol was studied on two soils belonging to the Haynie series (very fine sandy loams) collected from field and forested sites. Experimental investigations focused on the effect of HRP addition on sorption and desorption of target chemicals when present in solution alone, and when present as a mixture. Addition of HRP resulted in a dramatic increase ...

Radioresistant cells have been shown to correlate with poor outcome after radiotherapy. Here, we found that human telomerase reverse transcriptase promoter (hTERTp) had lower activity in laryngeal squamous carcinomas cells than in radioresistant variant cells. Combining radiotherapy with plasmid phTERTp-HRP, in which expression of enzyme horseradish peroxidase (HRP) controlled by hTERTp, result...

This paper introduces a simple new approach to object recognition from silhouettes. This new approach utilizes features extracted using an adaptive approximation technique called high-resolution pursuit (HRP). In this work, a comparatively small set of HRP features and a simple recognition scheme are used. We demonstrate the strengths of the HRP-based recognition scheme by discriminating among ...

A decade ago, the American Board of Radiology established a research pathway for residency training designed for individuals to simultaneously train in diagnostic radiology or radiation oncology and in basic science, clinical, or transitional investigation. This new pathway was called the ABR Holman Research Pathway, named for B. Leonard Holman, M.D., who first proposed this initiative to foste...

A sensitive and noble amperometric horseradish peroxidase (HRP) biosensor is fabricated via the deposition of gold nanoparticles (AuNPs) onto a three-dimensional (3D) porous carbonized chicken eggshell membrane (CESM). Due to the synergistic effects of the unique porous carbon architecture and well-distributed AuNPs, the enzyme-modified electrode shows an excellent electrochemical redox behavio...

In order to identify cerebellar terminals in the cat inferior olive which contain gamma-aminobutyricacid (GABA), a technique was developed combining anterograde transport of wheatgerm agglutinine-conjugated horseradish peroxidase (WGA-HRP) with gold-immunocytochemistry. With this technique both the HRP reaction product and the immunogold labeling can be visualized in a single ultrathin section....

Ultraviolet resonance Raman (UVRR) spectroscopy has been used to characterize the structure and hydrogen bonding state of the distal histidine (His42) in horseradish peroxidase (HRP) complexed with carbon monoxide (HRP-CO). The HRP-CO - HRP UVRR difference spectrum in D(2)O solution at pD 7.0 shows two positive peaks at 1408 and 1388 cm(-)(1), which are ascribable to medium-to-weak and strong h...

The interaction of a series of derivatives of tyrosine with horseradish peroxidase (HRP) and lactoperoxidase (LPO) was studied by using optical difference spectroscopy, c.d. and proton n.m.r. spectroscopy in order to reveal differences in the mode of binding of L-tyrosine and D-tyrosine, which are substrates of but react at different rates with the two peroxidases, to HRP and LPO. All the donor...
