A luminol-H2O2-HRP chemiluminescence system with high relative luminescent intensity (RLU) and long stabilization time was investigated. First, the comparative study on the enhancement effect of ten compounds as enhancers to the luminol-H2O2-HRP chemiluminescence system was carried out, and the results showed that 4-(imidazol-1-yl)phenol (4-IMP), 4-iodophenol (4-IOP), 4-bromophenol (4-BOP) and ...

BACKGROUND Carotid atherosclerotic plaque rupture is an important source of ischemic stroke. However, the prevalence of high-risk plaque (HRP) defined as plaques with luminal surface disruption, a lipid-rich necrotic core occupying >40% of the wall, or intraplaque hemorrhage in Chinese population remains unclear. This study uses carotid magnetic resonance imaging (CMRI) to investigate HRP preva...

Human synovial tissue cells in monolayer can be shown to take up and digest a soluble protein, horseradish peroxidase (HRP). Uptake of HRP was linear with increasing concentrations of substrate and cell protein and with time for up to 4 h. Low temperature (4 degrees C), and sodium fluoride, an inhibitor of glycolysis were the most effective metabolic inhibitors of endocytosis. In addition, colc...

BACKGROUND Zoonotic cutaneous leishmaniasis (ZCL) is an increasing public health problem in some endemic regions. Horseradish peroxidase (HRP) conjugated rabbit anti-Rhombomys opimus (R. opimus) Ig is needed for immunoblotting and ELISA tests used to explore the immune response of the rodents against the sand fly saliva. In this study, the production of HRP conjugated rabbit anti-R. opimus Ig w...

Cells of the 16-cell mouse embryo endocytose horseradish peroxidase (HRP) which becomes localized in most cases to a juxtanuclear position. Cells that have ingested HRP in intact embryos, and cells dissociated from embryos prior to culture in HRP, showed similar patterns of cytoplasmic distribution of the ingested enzyme. Cells in the embryo in situ were incubated in HRP, and then labelled with...

Ultrawideband (UWB) wireless communication technology, which appeared 20 years ago, is becoming popular in various fields because the ability to measure precise distance between UWB devices beyond being re-examined. The currently commercialized technology high-rate pulse repetition frequency (HRP) uses high-speed pulses of several tens megahertz, and direction measurements are made by using cha...

background: in this study, we evaluated the protective effects of water hyacinth root powder (hrp) on arsenic-mediated toxic effects in mice. methods: swiss albino mice, used in this study, were divided into four different groups (for each group n=5). the control group was supplied with normal feed and water, arsenic group (as-group) was supplied with normal feed plus arsenic (sodium arsenite)-...

In the definition of a crossed module $(T,G,rho)$, the actions of the group $T$ and $G$ on themselves are given by conjugation. In this paper, we consider these actions to be arbitrary and thus generalize the concept of ordinary crossed module. Therefore, we get the category ${bf GCM}$, of all generalized crossed modules and generalized crossed module morphisms between them, and investigate som...

In parotid acinar cells, horseradish peroxidase (HRP) administered via the main excretory duct is endocytosed from the apical cell surface in smooth C- or ring-shaped vesicles (Oliver, C. and A. R. Hand. 1979. J. Cell Biol. 76:207). These vesicles ultimately fuse with lysosomes adjacent to the Golgi apparatus. The present investigation extends these findings and examines the uptake and fate of ...

The ability of Pseudomonas syringae pv. tomato DC3000 to be pathogenic on plants depends on the Hrp (hypersensitive response and pathogenicity) type III protein secretion system and the effector proteins it translocates into plant cells. Through iterative application of experimental and computational techniques, the DC3000 effector inventory has been substantially enlarged. Five homologs of kno...
