Innovative approach to lymphadenectomy in breast sarcoma.

Unlabelled: Lymphatic dissemination is thought to be a rare event in breast sarcomas. The decision to perform axillary clearance is challenging. In our prospective cohort, we aimed to evaluate the frequency and factors determining lymph node (LN) involvement in breast sarcomas, with the aim of proposing a decision tree/algorithm for the realization of LN clearance in breast sarcomas.

The effect of hospital biocide sodium dichloroisocyanurate on the viability and properties of Clostridium difficile spores.

Unlabelled: Clostridium difficile is the primary cause of healthcare-associated diarrhoea globally and produces spores which are resistant to commonly used biocides and are able persist on contaminated surfaces for months. This study examined the effect of sublethal concentrations of the biocide sodium dichloroisocyanurate (NaDCC) on the viability of spores produced by 21 clinical isolates of C. difficile representing a range of PCR ribotypes.

Lithium conductivity in glasses of the Li2O-Al2O3-SiO2 system.

To improve the understanding of Li-dynamics in oxide glasses, i.e. the effect of [AlO4](-) tetrahedra and non-bridging oxygens on the potential landscape, electrical conductivity of seven fully polymerized and partly depolymerized lithium aluminosilicate glasses was investigated using impedance spectroscopy (IS).

Li diffusion and the effect of local structure on Li mobility in Li2O-SiO2 glasses.

Aimed to improve the understanding of lithium migration mechanisms in ion conductors, this study focuses on Li dynamics in binary Li silicate glasses. Isotope exchange experiments and conductivity measurements were carried out to determine self-diffusion coefficients and activation energies for Li migration in Li2Si3O7 and Li2Si6O13 glasses. Samples of identical composition but different isotope content were combined for diffusion experiments in couples or triples.

Effects of Eu3+ concentration on structural, optical and vibrational properties of multifunctional Ce(1-x)Eu(x)O2-delta) nanoparticles synthesized by thermolysis of 2,4-pentanedione complexes.

The 5-10 nm Ce(1-x)Eu(x)O(2-delta) (0 < or = x < or = 0.30) nanoparticles with fluorite structure were synthesized by thermal decomposition of Eu- and Ce-2,4-pentanedione complexes mixtures. X-ray line broadening analysis of mixed samples Ce(1-x)Eu(x)O(2-delta) (0.
