Treatment of cultured bovine adrenal chromaffin cells with the catecholamine transport blocker reserpine was shown previously to increase enkephalin levels severalfold. To explore the biochemical mechanism of this effect, we examined the effect of reserpine treatment on the activities of three different peptide precursor processing enzymes: carboxypeptidase E (CPE) and the prohormone convertase...
BACKGROUND The moderately homologous (approx. 60%) proteins Ara h 2 and Ara h 6 are the most potent peanut allergens. This study was designed to define the relative individual contributions of Ara h 2 and Ara h 6 to the overall allergenic activity of a crude peanut extract (CPE). METHODS Ara h 2 and Ara h 6 were removed from CPE by gel filtration chromatography. Ara h 2.01, Ara h 2.02 and Ara...
A new method was developed for simultaneous determination of copper, lead, and cadmium, based on their voltammetric response at a carbon paste electrode modified with hexagonal mesoporous silica (HMS) immobilized quercetin (HMS-Qu/CPE). Compared with quercetin modified carbon paste electrode (Qu/CPE) and quercetin ionic liquid modified carbon paste electrode (Qu-IL/CPE), the HMS-Qu/CPE exhibite...
To learn users’ preference, their feedback information is commonly modeled as scalars and integrated into matrix factorization (MF) based algorithms. Based on MF techniques, the preference degree is computed by the product of user and item vectors, which is also represented by scalars. On the contrary, in this paper, we express users’ feedback as constrained vectors, and call the idea constrain...
Four methods for the assay of human interferon in Vero cells were compared based on the inhibition of viral cytopathic effect (CPE) in tubes, the inhibition of CPE in microplates, the reduction of plaques, and the inhibition of quantitative hemadsorption. For inhibition of CPE, Sindbis virus, vesicular stomatitis virus, poliovirus type 2, and vaccinia virus were used for challenge. In the plaqu...
An active film was prepared by incorporating cortex Phellodendron extract (CPE, an active agent) into a soybean protein isolate (SPI). Different concentrations of CPE (0%, 10%, 12.5%, 15%, 17.5%, 20%, or 22.5%, w/w, based on SPI) were mixed into the films characterized by Fourier transform infrared spectroscopy, X-ray diffraction, scanning electron microscopy, thermogravimetry, tensile tests, a...
Hypoxanthine is the main product of purine metabolic degradation and previous studies have revealed that it is present in the sheep CSF and plasma in micromolar concentrations. The aim of this study was to elucidate the transport of this molecule across the sheep choroid plexus epithelium (CPE) as a monolayer in primary culture, to explore the mechanism of uptake by the apical side of the CPE a...
Efficient vaccine delivery to mucosal tissues including mucosa-associated lymphoid tissues is essential for the development of mucosal vaccine. We previously reported that claudin-4 was highly expressed on the epithelium of nasopharynx-associated lymphoid tissue (NALT) and thus claudin-4-targeting using C-terminal fragment of Clostridium perfringens enterotoxin (C-CPE) effectively delivered fus...
Clostridium perfringens enterotoxin (CPE) was found to possess interferon (IFN)-producing and mitogenic activities to human peripheral blood mononuclear cells. Both activities were demonstrated only in the T lymphocyte-rich fraction from healthy volunteers. The IFN produced appeared to be gamma-type since the activity of the IFN was neutralized by antiserum against human IFN-gamma. With formali...
colonized with CPE. Prospective studies using innovative laboratory techniques are needed on patients with CPE during outbreaks and in endemic settings over periods of time, while in the hospital and after discharge. These studies will help us further understand the natural history of CPE colonization and determine the host/patient, environmental, and microbial factors that may help us predict ...
