Liver abscesses in chronic granulomatous disease (CGD) are typically difficult to treat and often require surgery. We describe 9 X-linked CGD patients with staphylococcal liver abscesses refractory ...to conventional therapy successfully treated with corticosteroids and antibiotics. Corticosteroids may have a role in treatment of Staphylococcus aureus liver abscesses in CGD.

▪ Abstract This article reviews the standard-model prediction for the anomalous magnetic moment of the muon and describes recent updates of QED, electroweak, and hadronic contributions. Comparison ...of theory and experiment suggests a 2.4 σ difference if Formula: see text hadrons data are used to evaluate the main hadronic effects, but a smaller discrepancy if hadronic τ decay data are employed. Implications of a deviation for “new physics” contributions, along with an outlook for future improvements in theory and experiment, are briefly discussed.

In this paper we propose the operation of an all-optical logical gate based in a symmetric nonlinear directional coupler (NLDC) operating with a pulse position modulation (PPM). The performance of a ...symmetric NLDC realizing two-input AND/OR logical functions, which can be applied in transmission and processing of signals in all-optical form in TDM systems, is examined. This integrated symmetric NLDC logical gate operates with two ultrashort soliton light pulses (2ps), which are modulated in agreement with the technique of pulse position modulation (PPM). Initially, we evaluate the effect resulting of an increment in the PPM coding parameter offset (ε), for the temporal position of the output pulse, considering the anomalous group-velocity dispersion (GVD), nonlinear self phase modulation (SPM) and without loss propagation regime of input pulses, in the cores 1 and 2 of the NLDC. In this situation, we analyze the four possible situations for the two-input logical gate, modulating the 1 and 2 input pulses through temporal displacement and allowing a variation in the coding parameter offset. We can conclude that is possible to get AND/OR logical operations for the cores 1 or 2, without to insert PPM error, since a phase control (Δϕ) exists applied in agreement with the logical level of the input pulse in the core 1. Finally we define the truth table, considering the adequate phase difference and coding parameter offset for the stable operation of the AND/OR logical gate based in the symmetric NLDC.
