This study reports on the first example, to our knowledge, of the usefulness of an ultrasound (US)-irradiation during an enzyme adsorption step, for enhancing the performance of a redox-enzyme-based amperometric biosensor. Horseradish peroxidase (HRP) and thionine (Th) were coadsorbed from a mixed aqueous solution of HRP and Th onto a carbon-felt (CF) under US-irradiation for 5 min with an ultr...

Purpose: Relative dispersion analysis (RDA), a new high pass resolution perimetry (HRP) index, appears to capture a novel aspect of visual field abnormality. The aim of this study was to evaluate the correlation of RDA and other HRP indices with the Humphrey perimeter parameters. Methods: Fifty-six eyes were randomly recruited from among patients at the authors’ clinic. Twenty-nine eyes were cl...

Scanning electrochemical microscopy (SECM) was used to study horseradish peroxidase (HRP) immobilized with copolymer on insulating substrates (glass slide or polycarbonate membrane filter). Two methods were used to immobilize HRP: In the first, HRP was coimmobilized by cross-linking on a glass slide with a copolymer swelled in water to form a hydrogel; in the second, the same copolymer and avid...

This paper presents an advanced leg module developed for, HRP-2, a new humanoid robotics platform, which has been developed in the phase two of the Humanoid Robotics Project(HRP), a five year program sponsored by the Ministry of Economy, Trade and Industry of Japan (METI) from 1998FY to 2002FY. The biped locomotion ability of HRP-1, the humanoid robotics platform developed in the phase 1 of HRP...

A carbon nanotube (CNT)-based multiple cycle signal amplification strategy has been demonstrated for detection of single-digit foodborne pathogens with the naked eye. In the present design, CNTs are used as carriers for loading numerous horseradish peroxidase (HRP) and concanavalin A (ConA) tags, and multiple cycle signal amplification is achieved through the biotinylated anti-HRP antibody and ...

We have coupled gold nanoparticles with horseradish peroxidase (HRP) to assemble catalytic nanoconjugates (HRP-AuNPs) for glucose detection. We found that a proper mixing ratio of HRP/AuNPs can significantly improve catalytic activity for the cascade reaction, an effect arising from increased spatial coupling between enzymes. Such gold nanoparticle-based nanoconjugates are shown to be promising...

When an HRP or WGA-HRP solution was injected into the rostral midbrain including the oculomotor visceral nuclei, densely distributed HRP/WGA-HRP-positive granules were observed around the ganglion neurons in the accessory ciliary ganglion (ACG) and ectopic neurons in the communicating branch from the long ciliary nerve to the ACG. The same injections labeled fibers within the communicating bran...

Recently, adaptive approximation techniques have become popular for obtaining parsimonious representations of large classes of signals. These methods include method of frames, matching pursuit, and, most recently, basis pursuit. In this work, high resolution pursuit (HRP) is developed as an alternative to existing function approximation techniques. Existing techniques do not always efficiently ...

Previously reported rates of reaction between six mutant strains of the enzyme horseradish peroxidase (HRP) and a test substrate, 2-methoxyphenol, were found to correlate with characteristic binding distances computed using molecular simulation. The correlation (R(2) = 0.86) bears out a working hypothesis that, based on a quantitative structure-activity relationship (QSAR) we had previously dev...

Recent studies have defined several cell surface glycoproteins expressed in the developing nervous system of insect embryos that may be involved in axon outgrowth and guidance processes. These glycoproteins include the fasciclins and a group of receptor-linked protein tyrosine phosphatases (R-PTPs). In embryos, the fasciclins are localized to axonal subsets, while the R-PTPs appear to be expres...
