  Idiopathic facial aseptic granuloma is a chronic, benign, and painless facial nodule occurring exclusively in childhood. Its pathogenesis is unclear, although some interesting hypotheses have been advanced. On the basis of the relationship existing between this disease and recurrent chalazions and conjunctivitis, we hypothesize that it could be considered ...

Over the last few years, the coordination of phosphine-boranes and related Frustrated Lewis Pairs to transition metals has attracted considerable interest. These polyfunctional, ambiphilic ligands are very versatile. In particular, the Lewis acid site may participate in different ways to coordination, directly at the metal or in near periphery. These ...

Ion beam sputtering is a widely used technique to obtain patterned surfaces. Despite the wide use of this approach on different materials to create surface nanostructures, the theoretical model to explain the time evolution of the erosion process is still debated. We show, with the help of simulations, that two-time ...

Monomethylarginine, asymmetric dimethylarginine and symmetric dimethylarginine were separated on a Wakopak Combi ODS with an acetonitrile-100 mm potassium phosphate buffer (pH 7.0; 1:1, v/v). Dimethylarginines were derived from o-phthalaldehyde for the fluorescence detector and from 6-ferrocenyl-1-hexanethiol for the electrochemical detector. The detection limits of the dimethylarginines in spiked plasma were 0.3-0.5 ...

Central nervous system (CNS) HIV infection is a nearly universal facet of systemic infection. Although antiretroviral therapy is generally effective in suppressing this infection and reducing its severe complications, reports of continued neurological abnormalities have questioned whether treatment developed for systemic efficacy is optimized for CNS infection. Shikuma et al. ...

The terminal rhenium(I) phosphaethynolate complex [Re(PCO)(CO)(2) (triphos)] has been prepared in a salt metathesis reaction from Na(OCP) and [Re(OTf)(CO)(2) (triphos)]. The analogous isocyanato complex [Re(NCO)(CO)(2) (triphos)] has been likewise prepared for comparison. The structure of both complexes was elucidated by X-ray diffraction studies. While the isocyanato complex is linear, the ...

New theoretical ideas and empirical research show that very young children's learning and thinking are strikingly similar to much learning and thinking in science. Preschoolers test hypotheses against data and make causal inferences; they learn from statistics and informal experimentation, and from watching and listening to others. The mathematical framework ...

We previously described restrictive allograft syndrome as a form of chronic lung allograft dysfunction, demonstrating restrictive pulmonary function decline. However, the histopathological correlates of restrictive allograft syndrome have yet to be satisfactorily described. We hypothesized that pulmonary pleuroparenchymal fibroelastosis, as has recently been described in bone marrow transplant recipients, may ...
