Micro-patterned Ni thin films with well-defined 2D-structures are useful to examine electrochemical reaction kinetics of SOFC anodes. In this work, an electrode preparation method is developed yielding stable Ni pattern electrodes on YSZ, which facilitate long term measurements. Moreover, these stable electrodes allowed investigating the effect of the YSZ substrate orientation on the polarizati...

UNLABELLED Planning hepatic (90)Y radioembolization activity requires balancing toxicity with efficacy. We developed a dual-tracer SPECT fusion imaging protocol that merges data on radioactivity distribution with physiologic liver mapping. METHODS Twenty-five patients with colorectal carcinoma and bilobar liver metastases received whole-liver radioembolization with resin microspheres prescrib...

Several bioreactor systems are used for biological treatment of hydrogen sulfide. Among these, airlift bioreactors are promising for the bioconversion of hydrogen sulfide into elemental sulfur. The performance of airlift bioreactors is not adequately understood, particularly when directly fed with hydrogen sulfide gas. The objective of this paper is to investigate the performance of an airlift ...

which oxidizes H 2 S to persulfide. SQRs were initially identified in invertebrates, and their mammalian counterpart SQRs were later discovered (Theissen et al., 2003; Theissen and Martin, 2008). In the presence of O 2 and water, sulfur dioxygenase oxidizes persulfide to sulfite, which is combined with another persulfide molecule by sulfur transferase rhodanese in order to producing thiosulfate...

Palladium-catalyzed carbothiolation of terminal alkynes with azolyl sulfides affords various 2-(azolyl)alkenyl sulfides with perfect regio- and stereoselectivities. The present addition reaction proceeded through a direct cleavage of carbon-sulfur bonds in azolyl sulfides. The resulting adducts that are useful intermediates in organic synthesis are further transformed to multisubstituted olefin...

Twenty patients with blunt abdominal trauma were diagnosed as having splenic rupture by Tc-99m sulfur colloid scintigraphy. Because of the increased risk of infection in children following splenectomy, surgery was not performed and scintigraphic followup of the injured spleens was carried out. Thirteen patients were scanned at least 2 mo after trauma and the longest followup was 1 yr. Only thre...

Abstract Pre-operative lymphatic mapping for sentinel node identification is essential accurate staging in patients with several solid cancers and important prognostic implications. 99m Tc-labelled colloid lymphoscintigraphy intraoperative lymph detection using a gamma probe represent well-established nuclear medicine technique detailed imaging method thanks to the advent of hybrid multi-modali...

Jet nebulizers show an unreasonable variation in drug output and nebulization rates that leads to clinical and regulatory problems. Current evaluation methods appear inadequate for the purpose. Our objective was to evaluate Technetium-99m radiometry to study nebulizer parameters and the factors influencing it quantitatively. Drug output, output rate and residual mass and the effect of excipient...
