Cytoreductive nephrectomy has been the standard of care in metastatic renal-cell carcinoma for 20 years, supported by randomized trials and large, retrospective studies. However, efficacy targeted therapies challenged this standard. We assessed role patients with who were receiving therapies.
Germanium dioxide (GeO2) is a chemical analogue of SiO2. Furthermore, it also to some extent structural analogue, as the low- and high-pressure short-range order (tetrahedral octahedral) same. However, number differences exist. For example, GeO2 phase diagram exhibits smaller polymorphs, all three phases (crystalline, glass, liquid) have an increased sensitivity pressure, undergoing pressure-induced changes at much lower pressures than their equivalent SiO2 analogues. In addition, exist in...
The structure and properties of glasses melts in the MgO-Al2O3-SiO2 (MAS) CaO-MgOAl2O3- SiO2 (CMAS) systems play an important role Earth material sciences. Aluminum has a crucial influence these systems, its environment is still questioned. In this paper, we present new results using Raman spectroscopy 27Al nuclear magnetic resonance on MAS CMAS glasses. We propose Al/Si tetrahedral distribution glass network different Qn species for silicon essentially Q4 VAl aluminum. For glasses, increase...
ID21 beamline (ESRF) offers combination of μXRF, μXANES (2.0–9.1 keV), μXRD and μFTIR, increasingly used to analyse artistic ancient materials.
We investigate the structural and vibrational properties of glassy B2O3 using first-principles molecular dynamics simulations. In particular, we determine boroxol rings fraction f for which there is still no consensus in literature. Two numerical models containing either a low or high level are tested against gamut experimental probes (static structure factor, Raman, 11B 17O NMR data). show that only boroxol-rich model (f=75%) can reproduce full set observables. Total-energy calculations at...
We show for the first time that it is possible to acquire high-resolution heteronuclear NMR correlation experiments in solid state between second-order-broadened half integer quadrupolar nuclei (i.e., 27Al and 17O) using scalar J-coupling. The sensitivity of experiment dramatically improved at high fields (gain proportional fourth power principal field) with a combination signal enhancement techniques. This turns challenging into real tool. apply this characterize calcium aluminate glass...
4508 Background: Carmena was a randomized phase III trial, testing the benefit of CN followed by sunitinib (arm A) vs alone B), with stratification MSKCC risk groups in 450 mRCC patients. Based on this is not anymore recommended (NEJM, Mejean et al, 2018). However there are questions about which patients could still from CN, especially intermediate group. In present study, we investigated different subgroups trial to answer these questions. Methods: initially stratified according groups. For...
Multivalent elements are often incorporated into silicate glasses to enhance specific properties of the final product. However, for some them, these strongly depend on redox state multivalent elements. While behavior containing a single element is well studied, research in situ interaction between multiple scarce. In this study, XANES spectroscopy was used investigate high-temperature both Ce and Fe an aluminosilicate melt. The results were compared room temperature measurements. Our...
The association between common functional polymorphisms from the CYP17, CYP19, CYP1B1, and COMT genes involved in estrogen metabolism risk of prostate carcinoma was evaluated.The study investigated 1,983 white French men (1,101 patients with cancer 882 healthy controls) aged 40 98 years. different alleles genotypes were analyzed according to case-control status, aggressiveness pattern tumors, age at onset, family history cancers.The VV (high activity) genotype V432L polymorphism CYP1B1 (odds...
Structural data on silicate, aluminate, and aluminosilicate melts are difficult to measure understand at high temperature. X-ray absorption spectroscopy (XAS) performed in situ temperature has been used probe the local environment of low-Z elements (Al, Si, Ca). For fully tetrahedral network glasses, CaAl2Si2O8 (anorthite) CaAl2O4, modifications Al K-edge spectra with increasing can be attributed a structural rearrangement or an increase fivefold-coordinated Al. Ca3Al2O6 composition, where...
Calcium aluminate glasses are important materials where AlO-4/2 is the only network former. Aluminum in crystals or between CaO and Al2O3 can have different environments as a function of CaO/Al2O3 ratio. Using X-ray absorption at Al K- L-edges, Raman 27Al NMR spectroscopies, we determined structural surroundings glasses, crystals, melts this binary system. octahedral coordination high-Al2O3 content (>80 mol%) essentially fourfold with 4 bridging O atoms (BOs) contents 30 75 mol%. At around...
We evaluated the efficacy and outcomes of transcatheter arterial embolization for intractable bladder or prostate bleeding after failed conservative treatment.We retrospectively studied records 2 women 18 men with a mean +/- SD age 73 17.2 years referred between 1999 2008 selective pelvic angiography conventional therapy. Embolization was feasible in patients, including bilateral unilateral 13 5, respectively. It consisted superselective distal particulate glue vesical prostatic arteries 11...
