This study focuses on the interaction of the three components of the Bacillus cereus Nhe enterotoxin with particular emphasis on the functional roles of NheB and NheC. The results demonstrated that both NheB and NheC were able to bind to Vero cells directly while NheA lacked this ability. It was also shown that Nhe-induced cytotoxicity required a specific(More)
CONTEXT Imaging with [¹²³I]iodometomidate ([¹²³I]IMTO) has been shown to diagnose adrenocortical lesions with high sensitivity and specificity. OBJECTIVE Our objective was to evaluate the clinical utility of [¹²³I]IMTO imaging in adrenocortical carcinoma (ACC). DESIGN We conducted a prospective monocentric diagnostic study and a prospective case series(More)
BACKGROUND Laparoscopic donor nephrectomy decreases disincentives to donation frequently associated with the disadvantages of open surgery. However, concerns have been raised regarding graft quality, since the incidence of delayed graft function is higher when compared with open procedures. This may be caused by amelioration of kidney perfusion due to the(More)
The Human Immunodeficiency Virus type 1 (HIV-1) subtype C is currently the predominant subtype worldwide. Cell culture studies of Sub-Saharan African subtype C proviral plasmids are hampered by the low replication capacity of the resulting viruses, although viral loads in subtype C infected patients are as high as those from patients with subtype B. Here,(More)
CONTEXT Adrenal tumors are highly prevalent and represent a wide range of different pathological entities. Conventional imaging often provides only limited information on the origin of these lesions. Novel specific imaging methods are, therefore, of great clinical interest. OBJECTIVE We evaluated [(123)I]iodometomidate ([(123)I]IMTO) imaging for(More)
A comparative analysis on the relevance of the Bacillus cereus enterotoxins Nhe (nonhemolytic enterotoxin), HBL (haemolysin BL) and CytK (cytotoxin K) was accomplished, concerning their toxic activity towards different target cell lines. Overall, among the components secreted by the reference strains for Nhe and HBL, the enterotoxin complexes accounted for(More)
Dengue fever is a severe, widespread, and neglected disease with more than 2 million diagnosed infections per year. The dengue virus NS2B/NS3 protease (PR) represents a prime target for rational drug design. At the moment, there are no clinical PR inhibitors (PIs) available. We have identified diaryl (thio)ethers as candidates for a novel class of PIs.(More)
The Nhe enterotoxin from Bacillus cereus is known to induce cytotoxicity on Vero and CaCo-2 cells by ordered binding of its single components NheA, NheB, and NheC. This study aimed to elucidate functional sites on NheB by identifying the epitopes of the neutralizing monoclonal antibodies 1E11 and 2B11. The binding regions of both antibodies were determined(More)
