the stereochemistry of the actinide elements has recently undergone considerable development and a wide variety of coordination numbers and geometries have been observed. this structural versatility arises from the lack of strong crystal field effects for the 5f-electronic configurations as well as from the large ionic radii of these metal ions, which change markedly with oxidation number, or a...

BACKGROUND The transesophageal echocardiograhpy (TEE) has been studied worldwide. However, identifying additional factors on top of operator's experience and patient's cooperation which could influence the success of the procedure in unsedated patients with heart disease  is not well documented. METHODS Under the cross-sectional descriptive design, 85 target patients were fulfilling the crite...

BACKGROUND & OBJECTIVES Intraosseous (IO) access is an alternative to difficult intravenous (iv) access during emergency clinical situations. Existing IO solutions are expensive, require power supply and trained manpower; limiting their use in resource constrained settings. To address these limitations, a novel IO device has been developed. The objectives of this study were to evaluate function...

PURPOSE This study compared a subtotal colectomy to self-expandable metallic stent (SEMS) insertion as a bridge to surgery for patients with left colon-cancer obstruction. METHODS Ninety-four consecutive patients with left colon-cancer obstruction underwent an emergency subtotal colectomy or elective SEMS insertion between January 2007 and August 2014. Using prospectively collected data, we p...

Abstract Dendropsophini is a highly diverse clade with controversial phylogenetic and taxonomic history. Different generic arrangements have been proposed the monophyly of several clades supported or rejected. Previous evidence suggested that larval morphology could play an important role in our understanding evolution diversification Dendropsophini, although data are missing for most lineages,...

Abstract Catalytic ester-interchange reactions, analogous to mutation and recombination, allow new sequence information be written statistically into poly(ester-imide) chains based on NDI (1,4,5,8-naphthalenetetracarboxylic diimide) units. Thus, both the insertion of cyclic ester cyclopentadecanolide (“exaltolide”) an NDI-based homopolymer quantitative exchange between two different homopoly(es...
