The ability to continually gain customer loyalty in the midst of increasing competition, bargaining power and trust through appropriate business level strategies is a consistent challenge for service firms. This necessary order firms remain competitive increase growth. study therefore examined selected Nigeria. Quantitative method survey research design was employed study. primary population tw...

inflammatory process improves, FDG uptake should be diminished, at least in the affected vessels. This was confirmed in the two patients for whom we have a follow-up F18-FDG-PET. Nevertheless, this pathophysiological basis can cause some false-positive results, as FDG uptake can occur in atherosclerotic lesions with an accumulation of inflammatory cells. Usually these images are less clearly po...

We analyzed LTβR mRNA expression in piglets from birth to weaning and compared the differential expression between Escherichia coli F18-resistant and sensitive populations to determine whether this gene could be used as a genetic marker for E. coli F18 resistance. Sutai piglets of different age groups (8, 18, 30, and 35 days; N = 4 each) and piglets demonstrating resistance/sensitivity to E. co...

Post-weaning diarrhea and edema disease caused by F18 fimbriated E. coli are important diseases in newly weaned piglets and lead to severe production losses in farming industry. Protective treatments against these infections have thus far limited efficacy. In this study we generated nanobodies directed against the lectin domain of the F18 fimbrial adhesin FedF and showed in an in vitro adherenc...

Context. Among optical stellar interferometers, the CHARA Array located at Mt Wilson in California offers the potential of very long baselines (up to 330 m) and the prospect of coupling multiple beam combiners. This paper presents the principle and the measured performance of VEGA, Visible spEctroGraph and polArimeter installed in September 2007 at the coherent focus of the array. Aims. With 0....

as a nuclear approach, positron emission tomography (pet) is a functional imaging technique which is based on the detection of gamma ray pairs emitted by a positron-emitting radionuclide. there are certain limitations to this technique such as normal tissue uptake. therefore, it has been recommended that patients prepare before scanning. fasting for a short while before pet imaging is an exampl...

Background: Bacteriophages are viruses that infect bacteria and therefore are widespread in nature. Those that lyse the pathogen Salmonella enterica serovar Enteritidis (SE) should be expected in niches in which this bacterium thrives, among others the avian egg. Furthermore, bacteriophages could remain viable in this milieu. Results: Upon artificially infecting hen eggs with the SE bacteriopha...

Non-nucleoside reverse-transcriptase inhibitors (NNRTIs) are one of the key components of antiretroviral drug regimens against human immunodeficiency virus type 1 (HIV-1) replication. (+)-calanolide A, which is purified from the rainforest plant Calophyllum, is an anti-HIV-1/ tuberculosis drug. In our previous study, a library of (+)-calanolide A was constructed and one novel compound 10-chloro...

Adherence of F18 fimbrial Escherichia coli to porcine intestinal epithelial cells is mediated by the adhesin (FedF) of F18 fimbriae. In a previous study, we demonstrated the specificity of the amino acid residues between 60 and 109 as the receptor binding domain of FedF. In this study, different expression, secretion, and anchoring systems for the receptor binding domain of the FedF adhesin in ...
