HIV escape in the central nervous system (CNS) despite undetectable viral load in the plasma has been observed and may contribute to HIV-associated neurocognitive disorders. Favouring the use of HIV drugs with a good penetration into the CNS has been advocated, leading to the establishment of the CNS penetration-effectiveness (CPE) score. However, the relevance of this score is not fully establ...

We evaluated the performance characteristics of chromID CARBA and HardyCHROM Carbapenemase for the detection of carbapenemase-producing Enterobacteriaceae (CPE). A CPE prevalence study was conducted using chromID CARBA; this demonstrated that in low-prevalence settings, CPE screening agars may lack specificity, and confirmation of putative isolates is necessary.

Carboxypeptidase E (CPE) has recently been described as a neuroprotective protein, and in mice devoid of CPE, a complete loss of the hippocampal CA3 neurons is observed. The pattern of loss is characteristic of that caused by status epilepticus. We therefore set out to determine when this loss occurred, what might induce it and if it could be prevented. We found that the hippocampus was intact ...

12.8% in Greece and 7% in Israel; 27% acquired colonization during ICU stay occurred in the hospital in Israel. A low prevalence of CPE enteric carriage upon ICU admission was observed in this study, but important individual hospital variations in the incidence of ICU-acquired CPE were observed. Four hospitals (36%) had an incidence rate higher than 3%; in three of them nosocomial dissemination...

Carboxypeptidase E (CPE) is initially synthesized as a larger precursor containing an additional 14-residue propeptide that is highly conserved between human and rat. Previous studies have established that the proenzyme is enzymically active and that deletion of the pro region does not affect the expression of the active enzyme. In the present study the function of the pro region was examined b...

The mRNA for Rvp.1 (rat ventral prostate) increases in abundance before gland involution after androgen deprivation. Rvp.1 is homologous to CPE-R, the high-affinity intestinal epithelial receptor for Clostridium perfringens enterotoxin (CPE), and is sufficient to mediate CPE binding and trigger subsequent toxin-mediated cytolysis. Rvp.1 (claudin-3) and CPE-R (claudin-4) are members of a larger ...

The choroid plexus epithelium (CPE) secretes the major fraction of the cerebrospinal fluid (CSF). The Na(+)-HCO(3)(-) transporter Ncbe/Nbcn2 in the basolateral membrane of CPE cells is important for Na(+)-dependent pH(i) increases and probably for CSF secretion. In the current study, the anion transport inhibitor DIDS had no effect on the residual pH(i) recovery in acidified CPE from Ncbe/Nbcn2...

Tumor metastasis of epithelium-derived tumors is the major cause of death from malignant tumors. Overexpression of claudin is observed frequently in malignant tumors. However, claudin-targeting antimetastasis therapy has never been investigated. We previously prepared a claudin-4-targeting antitumor molecule that consisted of the C-terminal fragment of Clostridium perfringens enterotoxin (C-CPE...

34 35 Coupling parameter-estimation (CPE) that uses observations in a medium to 36 estimate the parameters in other media may increase the coherence and consistence of 37 estimated parameters in a coupled system, through the uses of co-varying relationship 38 between variables residing in different media. However, accurately evaluating the 39 strength of co-varying of different media is usually...

It has been shown that Clostridium perfringens isolates associated with food poisoning carry a chromosomal cpe gene, whereas nonfood-borne human gastrointestinal disease isolates carry a plasmid cpe gene. In addition, the chromosomal cpe gene isolates exhibit greater heat resistance as compared with the plasmid cpe strains. Therefore, the current study conducted ultrastructural measurements of ...
