The Ce is almost exclusively concentrated in the fluoritelike nanoprecipitates, while the Ho incorporates into both the planar arrays of nanoprecipitates and the superconducting matrix, where it substitutes for Y in the YBCO lattice. The present findings for Ce and Ho doping are in interesting contrast with our prior findings for Zr-doped
MOCVD films due to the fact that the Zr-doped films exhibit columnar precipitate arrays that produce a substantial improvement in J(c) for magnetic field orientations parallel to the YBCO c-axis, while no appreciable change is observed in either self-field or applied-field J(c) performance for field orientations parallel to the ab planes. These results suggest that improvement of the in-field J(c) of YBCO Combretastatin A4 films over an extended range of field angles could be achieved by doping strategies that simultaneously produce both ab-plane aligned and c-axis aligned precipitate arrays.

“The
management of residuals after completion of chemotherapy in advanced seminoma is controversial. It has been proposed that fluorodeoxyglucose-positron emission tomography (FDG-PET) can be used as a follow-up. In this study we investigated FDG-PET as a follow-up tool in advanced seminoma patients treated previously with chemotherapy or radiotherapy. Thirty-seven patients assigned to an advanced seminoma group based on CT and/or FDG-PET/CT and then treated with chemotherapy were included in the study. All these find more patients underwent FDG-PET/CT examination as a part of the follow-up scheme. Patients underwent retroperitoneal lymph node dissection (RPLND), radiotherapy, or were followed clinically by CT and/or 3-MA inhibitor PET/CT every 6 months. In 8 cases FDG-PET was positive: 5 of them underwent RPLND and 3 radiotherapy. Two patients with negative FDG-PET but positive CT also underwent RPLND. The remaining patients with negative FDG-PET results were followed up. FDG-PET/CT was false positive in one case >3 cm and one <3 cm, in 6 cases >3 cm it was true negative. While FDG-PET can find a viable tumor, there
also is an important question of false positive results. It was clinically proven that a negative FDG-PET was correlated with stable disease, but we were unable to examine specimens in these cases. Copyright (C) 2012 S. Karger AG, Basel”
“The frequency of epileptiform abnormalities (EAs) and correlates of EAs in children with attention deficit/hyperactivity disorder (ADHD) was investigated in a retrospective study. The total sample consisted of 607 children with ADHD from the only center diagnosing and treating ADHD in the region. EEGs were obtained in 517 cases, and EAs were found in 39(7.5%) children. Of these, 21(53.9%) showed generalized EAs, 16(41%) had focal EAs, and 2 (5.1%) had both. Rolandic spikes were observed in 9 cases (1.7% of the total group).
