A second strain of enterococcus (PA) producing beta-lactamase (Bla+ phenotype) was compared with the previously reported Bla+ enterococcus, strain HH22. As with the original strain, there was a marked inoculum effect when PA was tested with penicillin, ampicillin, and piperacillin; no difference was noted with methicillin, cephalothin, imipenem, or vancomycin; the difference with ticarcillin wa...

The objective of this study was to evaluate the pharmacokinetics of atazanavir (ATV), saquinavir (SQV), and ritonavir (RTV) in a boosted double-protease inhibitor (PI) therapy regimen without reverse transcriptase inhibitors (RTIs). The study design was as follows. Patients with limited RTI options received a PI combination of 300/100 mg ATV/RTV once daily and 1,000 mg SQV twice daily (group 1;...

The granulocyte-macrophage colony-stimulating factor (GM-CSF) receptor is expressed on normal and malignant hematopoietic cells as well as on cells from other organs in which it transduces a variety of functions. Despite the widespread expression and pleiotropic nature of the GM-CSF receptor, little is known about its assembly and activation mechanism. Using a combination of biochemical and fun...

The receptor for granulocyte/macrophage colony-stimulating factor (GM-CSF) is composed of two chains, alpha and betac. Both chains belong to the superfamily of cytokine receptors characterized by a common structural feature, i.e., the presence of at least two fibronectin-like folds in the extracellular domain, which was first identified in the growth hormone receptor. The GM-CSF receptor (GMR)-...

This work presents a first approach in high fidelity current measurement using GMR (giant magneto resistance) sensors combined along with an air coil to obtain a wide bandwidth current probe. The proposed probe is a prototype of a clamping version capable to capture currents of +/400 amperes from DC up to 10 MHz. This paper presents an argument for this equipment as well as the implementation o...

This contribution reports on comparative studies on giant magnetoresistance (GMR) in carbon nanotubes (CNTs) and graphene nanoribbons of similar aspect ratios (i.e perimeter/length and width/length ratios, for the former and the latter, respectively). The problem is solved at zero temperature in the ballistic transport regime, by means of the Green’s functions technique within the tight-binding...

In this paper, we review the contributions which MBE (molecular beam epitaxy) has made to the field of GMR (giant magnetoresistance) and interlayer exchange coupling in magnetic multilayers and sandwiches. A historical overview is given and a key advantage of MBE over alternative preparation techniques is emphasized: the ability to probe in situ the growth and structure of these materials. Rece...

All materials exhibit magnetoresistance ~MR!, that is, a change in resistance when a magnetic field is applied. This property is stronger in magnetic than in nonmagnetic materials. Magnetoresistance is a phenomenon of great interest due to its technological applications. Among the different types of MR observed in magnetic materials, the following three should be remarked: anisotropic magnetore...
