Abstract
10542 Background: Multimodal approach had improved outcomes of non-metastatic osteosarcoma. This study was to compare outcomes between doublet (AP; doxorubicin and cisplatin) and triplet (IAP; AP and ifosfamide) neoadjuvant chemotherapy for non-meteastatic osteosarcoma of extremity in a single institute. Methods: A total of 124 osteosarcoma patients were enrolled. In AP group, doublet regimen was given to 77 patients from 1991 to 1999, who received intra-arterial cisplatin(120mg/m2) at day 1 and intravenous doxorubicin (25mg/m2) for 3 days. In IAP group, triplet regimen was given to 49 patients from 2000 to 2007, who received ifosfamide additionally at a dose of 2.5g/m2/day for 3 days. After completion of 3 cycles of chemotherapy, patients underwent limb-salvage surgery. We assessed tumor response according to pathologic tumor necrosis, and treated further adjuvant chemotherapy. In AP group, responder received 3 more cycles of AP, while non-responders received 6 cycles of ifosfamide-contaning regimens. In IAP group, all patients had 3 more cycles of IAP chemotherapy. Results: The median follow-up duration was 5.2 years (0.4–16.7). The most frequent site and histology were distal femur and osteoblastic type. Overall pathologic response was more than 90% tumor necrosis in 74.8% of patients. Total necrosis of tumor was also found in 46 patients (37.4%). There was no difference between two groups in pathologic response (76.3% vs. 72.3%; p=0.62) or other clinico-pathologic parameters. Tumor recurrence was occurred in 31.5% of patients with the most common site of lung (84.6%). There was no difference between two groups in recurrence (p=0.17) or lung metastasis (p=0.53). There were no statistical differences in disease free survival (p=0.75) and overall survival (p=0.07) between two groups. In toxicity profiles, there were more hematologic toxicity in IAP group (febrile neutropenia,p<0.001; thrombocytopenia,p<0.05), while there were no statistical differences in treatment related death. Conclusions: The addition of ifosfamide to doxorubicin and cisplatin in neoadjuvant chemotherapy did not show improved outcomes in this study. Further trials are required to elucidate optimal neoadjuvant chemotherapy and effective salvage regimens. No significant financial relationships to disclose.

Abstract
We have studied the mass renormalization in Ca2-xSrxRuO4 (x=0.2) using high-resolution angle-resolved photoemission spectroscopy. We observed precise band dispersions near the Fermi level (E_{F}) and the corresponding Fermi surfaces. A characteristic flat band with approximately 4 meV dispersion accompanying sharp quasiparticle (QP) peaks shows up in a limited momentum region around (pi, 0). The QP peak rapidly evolves below the crossover temperature T;{*} approximately 20 K, which agrees well with the mass enhancement behavior indicated by thermal, magnetic, and transport properties. We discuss the origin of the mass renormalization in relation to the local flat band at (pi, 0) possibly derived from the gamma (d_{xy}) band.

Abstract
We have developed an ultrahigh-vacuum instrument for resonant diffraction experiments using polarized soft x rays in the energy range of hnu=300-2000 eV at beamline BL17SU of SPring-8. The diffractometer consists of modified differentially pumped rotary feedthroughs for theta-2theta stages, a sample manipulator with motor-controlled x-y-z-, tilt (chi)-, and azimuth (phi)-axes, and a liquid helium flow-type cryostat for temperature dependent measurements between 30 and 300 K. Test results indicate that the diffractometer exhibits high reproducibility (better than 0.001 degrees ) for a Bragg reflection of alpha-quartz 100 at a photon energy of hnu=1950 eV. Typical off- and on-resonance Bragg reflections in the energy range of 530-1950 eV could be measured using the apparatus. The results show that x-ray diffraction experiments with energy-, azimuth-, and incident photon polarization-dependence can be reliably measured using soft x rays in the energy range of approximately 300-2000 eV. The facility can be used for resonant diffraction experiments across the L-edge of transition metals, M-edge of lanthanides, and up to the Si K-edge of materials.

Abstract
We study the electronic structure of the filled skutterudite CeOs4Sb12 using photoemission spectroscopy (PES). Soft x-ray excited Ce 3d-4f resonant PES confirms the existence of Ce 4f states at the Fermi level (EF). Temperature dependent high-resolution laser-PES spectra reveal a pseudogap formation around EF, which can be explained in terms of the hybridization gap. Simultaneously, a sharp feature is formed just above EF with decreasing temperature. The heavy-fermion-like specific heat is attributed to the occupation of this feature. The results identify the origin of the anomalous coexistence of heavy-fermion and pseudogap behavior in terms of a symmetry dependent hybridization.

Abstract
High energy resolution photoelectron spectroscopy of conduction electrons in the vicinity of the Fermi edge in Al and Au at excitation energies of 880 and 7940 eV was carried out using synchrotron radiation. For the excitation energy of 7940 eV, the observed Fermi energy of Al shows a remarkable shift to higher binding energy as compared with that of Au, with accompanying broadening. This is due to the recoil effect of the emitted photoelectrons. The observed spectra are well reproduced by a simple model of Bloch electrons based on the isotropic Debye model.

Abstract
BACKGROUND Performance characteristics of novel rapid drug susceptibility tests (DST) for Mycobacterium tuberculosis may change when moving from research to implementation in actual public health practice. We describe the performance characteristics of a direct, rapid DST when implemented in Lima, Peru. METHODS A district laboratory validated conventional proportions and nitrate reductase methods. We collected data on samples submitted for DST from January 2005 to June 2007 and calculated frequency of testing and results, and median time to test results. RESULTS A total of 4102 DSTs were performed by conventional DST and 895 by nitrate reductase. Results were obtained from 72.8% of samples by conventional DST and from 70.2% of those processed by Griess; respectively 26.4% and 31.5% were multidrug-resistant tuberculosis. The median time from sample collection to test result was 31 days for Griess vs. 99 days for conventional DST. CONCLUSIONS Preliminary experience with the Griess method demonstrates favorable performance under program conditions.

Abstract
We have reexamined the valence-band (VB) and core-level electronic structure of NiO by means of hard and soft x-ray photoemission spectroscopies. The spectral weight of the lowest energy state was found to be enhanced in the bulk sensitive Ni 2p core-level spectrum. A configuration-interaction model including a bound state screening has shown agreement with the core-level spectrum and off- and on-resonance VB spectra. These results identify the lowest energy states in the core-level and VB spectra as the Zhang-Rice (ZR) doublet bound states, consistent with the spin-fermion model and recent ab initio calculations within dynamical mean-field theory. The results indicate that the ZR character first ionization (the lowest hole-addition) states are responsible for transport properties in NiO and doped NiO.

Abstract
Laser-excited photoemission spectroscopy is used to show that the doped carriers in metallic or superconducting diamond couple strongly to the lattice via high-energy (approximately 150 meV) optical phonons, with direct observations of localized Franck-Condon multiphonon sidebands appearing as Fermi-edge replicas. It exhibits a temperature-dependent spectral weight transfer from higher to lower energy sidebands and zero-phonon Fermi-edge states. The quantified coupling strength shows a systematic increase on lowering temperature, implicating its relation to the normal state transport and superconductivity.
