CONCLUSION: These two successful interventions extended the findings of previously published data for the successful treatment of behavioral challenges using a flexible support-oriented intervention that combines behavioral, cognitive, and executive function components.”
“We demonstrate that the NC stretching band of 2,6-dimethylphenylisocyanide (2,6-DMPI) adsorbed on poly(ethylenimine)-capped Au film is very susceptible to the kind of biogenic volatile organic compounds (VOCs) exposed, suggesting that the isocyanide-adsorbed noble metal nanostructures
can be used as a platform for a biogenic VOC sensor operating via surface-enhanced Raman scattering Stattic chemical structure (SERS). Specifically, first we demonstrate
find more that highly SERS-active Au films can easily be fabricated onto the inner surfaces of glass capillaries, being able to measure the SERS spectra of 2,6-DMPI facilely and thus to monitor the shift of its NC stretching band rapidly in response to a variety of biogenic VOCs including isoprene, farnesol, and (+)-alpha-pinene. Secondly, we are able to deduce from the NC stretching peak shifts that farnesol must act as an electron acceptor so as to increase the surface potential of Au nanoparticles, while isoprene and (+)-alpha-pinene are electron donors, resulting in the decrease in the surface potential of Au nanoparticles. To our knowledge, this is the first report, informing the applicability of SERS, though indirect, in the detection of biogenic VOCs. (C) 2012 Elsevier B.V. All rights reserved.”
“Objective and background data: This work is dedicated to investigation of influence of different values of pH on mechanisms of binding of human Vorinostat inhibitor serum albumin (HSA) with markers of fluorescent family – eosin, erythrosin and fluorescein. For this purpose were detected changes in markers fluorescence, in markers molecular association, in the effective constants of binding of markers to HSA and also in changes in related chemical bonds in HSA-marker association. Such analysis of changes in binding of biomolecules (such as proteins) with different
ligands (such as markers) is extremely interesting from the point of view of a biomedicine and pharmaceuticals, so from the point of view of bionanotechnology: for example, at creation of new drugs.\n\nMethods: The investigations of steady-state fluorescence, polarized fluorescence, molecular association of markers of fluorescein family in HSA solutions are presented in this work, also the analysis of changes in related chemical bonds in HSA-marker association by Raman spectroscopy is done, and also the effective constants of binding of markers to HSA are calculated.\n\nResults and conclusion: All investigations show the leading role of chemical and electrostatic interactions between markers and HSA.
